RISK FACTOR SUMMARY

Our business is subject to a number of risks that if realized could materially affect our business, financial condition, results of operations, cash

flows and access to liquidity. These risks are discussed more fully in the “Risk Factors” section of this Annual Report on Form 10-K. Our principal risks
include the following:

• We have incurred significant losses since inception, expect to incur significant and increasing losses for at least the next several years, and may
never achieve or maintain profitability. Our net losses were $344.9 million, $304.7 million and $127.5 million for the years ended December 31,
2020, 2019 and 2018, respectively.

• We have not yet successfully obtained marketing approvals nor commercialized any pharmaceutical products, which may make it difficult to
evaluate our future prospects. We will need to transition from a company with a development focus to a company capable of supporting
commercial activities.

• We will need substantial additional funding, to allow us to support both the systemic and ophthalmological pegcetacoplan programs through
commercial launch, and if we are unable to raise capital when needed, we could be forced to delay, reduce or eliminate certain product
development programs or commercialization efforts. We believe that our existing cash, cash equivalents and marketable securities will enable us
to fund our operating expenses and capital expenditure requirements at least into the second half of 2022.

•

If we receive regulatory approval for the use of pegcetacoplan as a treatment for PNH or if our agreement with SFJ Pharmaceuticals Group, or
SFJ, is terminated prior to receiving such approval in specified circumstances, we will be required to make substantial payments to SFJ pursuant
to our development funding agreement. If we do not have sufficient funding or cash flow from our business to meet our payment obligations
under the development funding agreement, SFJ could exercise its remedies as a holder of a first priority security interest in our assets and our
business could be materially harmed.

• We  are  dependent  on  the  successful  development  and  commercialization  of  pegcetacoplan.  If  we  are  unable  to  develop,  obtain  marketing
approval for or successfully commercialize pegcetacoplan or if we experience significant delays in doing so, our business could be harmed.

•

•

•

•

The regulatory approval process is expensive, time consuming and uncertain and may prevent us or our collaborators such as Swedish Orphan
Biovitrum AB (Publ), or Sobi, from obtaining approvals for the commercialization of pegcetacoplan or any of our product candidates that we
develop. As a result, we cannot predict when or if, and in which territories, we, or our collaborators, will obtain marketing approval to
commercialize pegcetacoplan or any other product candidate that we develop.

The COVID-19 pandemic may affect our ability to conduct our ongoing clinical trials, delay the initiation of planned and future clinical trials,
disrupt regulatory activities, or have other adverse effects on our business and operations. In addition, the COVID-19 pandemic may adversely
impact economies worldwide, which could result in adverse effects on our business and operations and ability to raise capital.

There are no approved therapies that act by inhibiting C3 and only two approved therapies in our target indications that act by inhibiting the
complement system. We may not be able to successfully develop and commercialize pegcetacoplan or other product candidates.

If clinical trials of our product candidates fail to satisfactorily demonstrate safety and efficacy to the U.S. Food and Drug Administration, or
FDA, the European Medicines Agency, or EMA, and other regulators, we may incur additional costs or experience delays in completing, or
ultimately be able to complete, the development and commercialization of these product candidates.

• We rely on third parties to conduct our clinical trials and to manufacture and distribute our product candidates for our clinical trials. We contract
with third parties for the manufacture, storage and distribution of our product candidates for clinical trials as well as in connection with our
commercialization efforts. This reliance on third parties increases the risk that we will not have sufficient quantities of our product candidates or
such quantities at an acceptable cost, which could delay, prevent or impair our development or commercialization efforts. If these third parties do
not perform satisfactorily, our development or commercialization efforts could be delayed or impaired.

•

•

Our prospects for the development and commercialization of our product candidates will depend in significant part on the success of our
collaboration with Sobi for the global co-development and commercialization of systemic pegcetacoplan outside of the United States.  Our ability
to generate revenues from this collaboration will depend on Sobi.

If we fail to comply with our obligations under our existing and any future intellectual property licenses with third parties, we could lose license
rights that are important to our business, including our patent license agreements with the University of Pennsylvania under which we license
patents with claim that recite a class of compounds generically covering our lead product candidates, pegcetacoplan and APL-9, and that
specifically recite the active component.

Item 1. Business.

PART I

We are a clinical-stage biopharmaceutical company focused on the development of novel therapeutic compounds to treat disease through the

inhibition of the complement system, which is an integral component of the immune system, at the level of C3, the central protein in the complement
cascade. We believe that this approach can result in broad inhibition of the principal pathways of the complement system and has the potential to effectively
control a broad array of complement-dependent autoimmune and inflammatory diseases.

We have the most advanced clinical programs targeting C3 with Phase 3 clinical trials of our lead product candidate, pegcetacoplan, in multiple

indications. We believe that pegcetacoplan has the potential to be a best-in-class treatment that may address the limitations of existing treatment options or
provide a treatment option where there currently is none. Pegcetacoplan has already shown activity that we believe is clinically meaningful in clinical trials
for several distinct medical conditions, including geographic atrophy in age-related macular degeneration, or GA; paroxysmal nocturnal hemoglobinuria, or
PNH; cold agglutinin disease, or CAD; and C3 glomerulopathy, or C3G. We are developing pegcetacoplan and other product candidates, including APL-9,
targeting C3 through various routes of administration and plan to conduct clinical trials of these compounds in additional complement-dependent
indications.

In October 2020, we entered into a collaboration and license agreement, or the collaboration agreement, with Sobi.  Under the collaboration
agreement, we agreed to co-develop pegcetacoplan for systemic indications, including PNH, CAD and hematopoietic stem cell transplantation-associated
thrombotic microangiopathy, or HSCT-TMA, in hematology; C3G and immune complex membranoproliferative glomerulonephritis, or IC-MPGN, in
nephrology; and amyotrophic lateral sclerosis, or ALS, in neurology.  Sobi has exclusive ex-U.S. commercialization rights for systemic pegcetacoplan.  We
retain commercialization rights for systemic pegcetacoplan in the United States and worldwide commercial rights for ophthalmological pegcetacoplan,
which includes our GA program in addition to worldwide commercialization rights for APL-9 and other product candidates targeting C3.

Ophthalmological pegcetacoplan

GA. We initiated a Phase 3 clinical program consisting of two Phase 3 clinical trials evaluating ophthalmological administration of pegcetacoplan in
patients with GA in September 2018. We refer to these trials as the DERBY and OAKS trials. Both trials are fully enrolled and we expect to announce top-
line data from these trials in the third quarter of 2021. 

In our Phase 2 clinical trial of pegcetacoplan in patients with GA, treatment with pegcetacoplan resulted in a significant reduction in the rate of GA

lesion growth over 12 months.

Additionally, data released in October 2020 from a post hoc analysis of seven patients in our Phase 1b trial of pegcetacoplan in patients with
advanced GA and low vision demonstrated a trend in reduced lesion growth in eyes treated with pegcetacoplan versus untreated fellow eyes after 18
months of treatment.

Systemic pegcetacoplan

We are developing pegcetacoplan with Sobi for systemic administration in several indications, including PNH, C3G, IC-MPGN, ALS, CAD and

HSCT-TMA.

PNH. In June 2018, we initiated a Phase 3 clinical trial evaluating pegcetacoplan in 80 patients with PNH who exhibited signs of moderate to severe

anemia, specifically with an inclusion criterion of hemoglobin level of less than 10.5 g/dL, while being treated with eculizumab, an approved therapy for
PNH that is marketed as Soliris. We refer to this trial as the PEGASUS trial.

In January 2020, we announced top-line data from the PEGASUS trial that showed that pegcetacoplan met the trial’s primary efficacy endpoint,
demonstrating superiority to eculizumab, with a statistically significant improvement in adjusted means of 3.8 g/dL of hemoglobin at week 16 (p < 0.0001),
and promising results in key secondary endpoints. Additional data from the PEGASUS trial presented in June 2020 and December 2020 demonstrated
increased hemoglobin levels, reduced transfusion requirements and improved key markers of hemolysis across the patient population, both in patients with
high transfusion requirements and in patients with low or no transfusion requirements, which improvements were sustained through 48 weeks of
treatment.  In the PEGASUS trial, the safety profile of pegcetacoplan was comparable to that of eculizumab.  

In September 2019, we initiated a second Phase 3 clinical trial in patients with PNH who have not been treated with eculizumab within three months

before entering the trial. We refer to this trial as the PRINCE trial. The PRINCE trial is fully enrolled and we intend to present top-line data in the second
quarter of 2021.

4

 
 
 
 
We submitted a new drug application, or NDA, to the FDA and a marketing authorization application, or MAA, to the EMA for pegcetacoplan for
the treatment of PNH in September 2020. The FDA accepted the NDA and set the Prescription Drug User Fee Act, or PDUFA, target action date for May
14, 2021.  The EMA validated the MAA in October 2020, with the potential for a European Commission decision on the MAA in the second half of 2021.  

C3G/IC-MPGN. We have initiated and will continue to lead our registrational program in C3G / IC-MPGN.  In October 2020, we reported data from

the Phase 2 DISCOVERY trial in five C3G patients treated with pegcetacoplan for 48 weeks.  We initiated a Phase 2 randomized, controlled trial in up to
12 patients with post-kidney transplant recurrence of C3G or IC-MPGN, in October 2020 and we expect to dose the first patient in this trial in the first half
of 2021. We refer to this trial as the NOBLE trial. We also plan to begin a Phase 3 clinical trial in patients with native kidney or post-transplant recurrence
of C3G or IC-MPGN, having reduction of proteinuria as its primary endpoint, in the second half of 2021.

ALS.  We have initiated a randomized, placebo-controlled Phase 2 clinical trial of pegcetacoplan in approximately 200 adults with sporadic
ALS.  We refer to this trial as the MERIDIAN trial. We treated the first patient in the MERIDIAN trial in November 2020 and expect to complete
enrollment for the MERIDIAN trial in the second half of 2021.

CAD and HSCT-TMA. Under our collaboration, Sobi will lead development activities for CAD and HSCT-TMA with a Phase 3 clinical trial in CAD

and a Phase 2 clinical trial in HSCT-TMA, both planned to begin in 2021.  In our Phase 2 clinical trial of pegcetacoplan in patients with CAD, patients
achieved increased hemoglobin levels, reduced reticulocytes and bilirubin levels, and reduced LDH levels compared to baseline.

Pipeline

We are developing pegcetacoplan and other product candidates, including APL-9, targeting C3 through various routes of administration.  We plan to

conduct clinical trials of these compounds in additional complement-dependent indications.

APL-9 is a C3 modulator designed to be intravenously administered for acute use.  In May 2020 we initiated a Phase 1/2 randomized, placebo-

controlled clinical trial of APL-9 in 66 patients with respiratory failure including acute respiratory distress syndrome, or ARDS, secondary to COVID-19.
We expect to report results from this trial in the second quarter of 2021.

We are also developing APL-9 for the prevention of complement immune system activation coincident with adeno-associated virus, or AAV, vector

administration for gene therapies and other indications.

We plan to advance three new product candidates into clinical development by the end of 2022.

Our Approach

The complement system plays a pivotal role in both innate and adaptive immune systems. Complement proteins are produced primarily by the liver

and circulate in the blood and through the body’s tissues. The complement system may be activated through three principal pathways, known as the
classical, lectin and alternative pathways, each of which requires the C3 protein to enable three principal immune responses: opsonization, inflammation
and formation of the membrane attack complex, or MAC. When C3 is activated, C3 fragments, such as C3b, tag cell surfaces in a process called
opsonization, which marks the cells for removal from tissues or the bloodstream. Two other fragments, C3a and C5a, are released, contributing to
inflammation in the surrounding tissues. Further complement activation causes membrane attack complex formation on cell surfaces, piercing holes and
causing cells to lyse, or rupture, and others to depolarize or lose membrane potential.

5

 
 
The following figure depicts the complement system, its three principal activation pathways and its principal effects:

Under conditions of excessive or uncontrolled activation, the complement system is believed to play a key role in the incidence and progression of
several autoimmune and inflammatory diseases. In these diseases, the complement system acts directly through tissue destruction by the membrane attack
complex and indirectly by signaling other elements of the immune system to inappropriately target otherwise healthy tissues. Because the contribution of
complement activation to the development and progression of these diseases is not fully understood, it has been difficult to develop therapeutics that
ameliorate the conditions contributing to these diseases by targeting only one of the complement activation pathways.

Complement activation and its effects can be inhibited in multiple ways. By targeting complement proteins upstream of C3, one of the three
principal activation pathways can be inhibited. For example, inhibition of factor B or factor D results in inhibition of the alternative pathway, but not the
classical or lectin pathways. The complement system can also be inhibited by targeting complement proteins downstream of C3, which results in limited
inhibition of complement effects. For example, inhibition of C5 leads to inhibition of the formation of the membrane attack complex and C5a-mediated
inflammation but does not affect opsonization or C3a-mediated inflammation.

We have designed pegcetacoplan to target complement proteins centrally at the level of C3. We believe that this approach can result in broad
inhibition of the complement pathways and has the potential to effectively control complement-dependent diseases. We believe that pegcetacoplan has the
potential to be a best-in-class treatment and may address the limitations of existing treatment options or provide a treatment option where there is none.

Our Strategy

We aim to become a leading biopharmaceutical company focused on the discovery, development and commercialization of therapeutics to treat

autoimmune and inflammatory diseases through complement inhibition. We hold commercialization rights for systemic pegcetacoplan in the United States
and worldwide commercialization rights to ophthalmological pegcetacoplan, which includes our GA program, in addition to worldwide commercialization
rights for APL-9 and other novel compounds targeting C3. To achieve our goals, we are pursuing the following strategies:  

•

•

Complete Phase 3 clinical development and prepare for regulatory submission of pegcetacoplan in GA. We are developing pegcetacoplan
as monotherapy for GA, administered by intravitreal injections. We expect to announce data from the DERBY and OAKS trials in the third
quarter of 2021 and to prepare submissions to regulatory authorities for marketing approval of pegcetacoplan as a treatment of geographic
atrophy.  

Prepare for commercialization of pegcetacoplan in PNH. We are developing pegcetacoplan as monotherapy for patients with PNH,
administered by subcutaneous injection, and are preparing to commercialize systemic pegcetacoplan in the United States and to support
Sobi’s commercialization efforts in the rest of the world. We submitted a new drug

6

 
 
 
 
application, or NDA, to the FDA and a marketing authorization application, or MAA, to the EMA for pegcetacoplan for the treatment of PNH
in September 2020. The FDA accepted the NDA and set the Prescription Drug User Fee Act, or PDUFA, target action date for May 14,
2021.  

•

•

Continue clinical development of systemic pegcetacoplan in other indications, including ALS and C3G/IC-MPGN. We are developing
pegcetacoplan for patients with C3G and C3G/IC-MPGN, administered by subcutaneous injection. Sobi has primary responsibility for the
clinical development pegcetacoplan for patients with CAD and HSCT-TMA.

Continue development and expansion of our pipeline. We plan to continue development of treatments for a broad range of complement-
dependent autoimmune and inflammatory diseases with pegcetacoplan and additional new product candidates.

Our Programs

Our lead product candidate, pegcetacoplan, is a C3 inhibitor. Pegcetacoplan is a conjugate of a compstatin analogue, formulated both for
ophthalmological administration by injections directly into the eye, and systemic administration by subcutaneous injection, which is an injection into the
tissue under the skin. We are developing pegcetacoplan and other product candidates, including APL-9, targeting C3 through various routes of
administration.

We are developing pegcetacoplan to be injected intravitreally as a monotherapy for patients with ophthalmological indications, including geographic

atrophy, or GA.  

Geographic Atrophy

Background

GA is a type of advanced age-related macular degeneration, or AMD. According to the Brightfocus Foundation, over ten million people in the

United States have some form of AMD. AMD is a disorder of the central portion of the retina in the eye, known as the macula, which is responsible for
central vision and color perception. AMD affects vision in one or both eyes and results in progressive and chronic degeneration of the macula, often
resulting in irreversible vision loss. AMD is a disease of aging, typically occurring after

the age of 50. In the early stage of the disease, yellow deposits, or drusen, appear under the retina. Over time, the disease can progress to an intermediate
stage where drusen deposits grow larger and other changes reflective of disease progression appear and then to an advanced stage associated with
progressive and often severe vision loss which may be characterized as either GA or wet AMD. GA is characterized by a degenerative process resulting in
the progressive loss of retinal cells, which over the course of several years results in blindness. Based on published studies, we believe that at least five
million people worldwide, including at least one million people in the United States, including have GA.

At the American Academy of Ophthalmology, or AAO, in November 2020, a retrospective study of 69,000 patients diagnosed with GA was

presented that analyzed changes in visual acuity and disease progression over two years.  The analysis was presented by Verana Health, a data analysis
group in retinal diseases under a collaboration with us, and the AAO’s IRIS® (Intelligent Research in Sight) Registry, the nation’s first comprehensive
clinical registry for eye disease. Key findings from the real-world clinical data showed: 

•

•

•

At the first study visit, patients presented with relatively preserved vision, especially in eyes with extrafoveal GA lesions (lesions outside the
fovea, which is the central portion of the retina). However, patients with extrafoveal and foveal GA lesions progressively lost vision over time at
a rate of approximately five letters on a vision chart per year. 
Progression from GA to new onset wet AMD was observed in 4.7% of patients with bilateral GA (GA in both eyes) and 13.3% of patients with
wet AMD in the contralateral eye (AMD in the non-treatment eye) during the first 12 months. The rate at 24 months was 8.2% and 21.6% in
bilateral GA and wet AMD in the contralateral eye, respectively. 
A large proportion of GA patients did not return for a follow-up visit after two years. Of the GA patients potentially eligible for inclusion in the
analysis, only 40% had a follow-up visit after two years and were ultimately included in the study. 

The mechanism by which complement activation is upregulated and can damage the retina is poorly understood. However, we believe that the

upregulation of complement activation due to immune dysregulation damages retinal cells in two ways. First, retinal cells are damaged by inflammation
caused by increased levels of C3a and C5a. Second, the increased deposition of C3b on the cell surface of retinal cells caused by complement activation,
combined with the limited ability of cells to remove C3 activated fragments such as C3b, leads to the accumulation of C3 fragments on the retinal cells.
The presence of C3a and C5a, as well as C3 fragment deposition on retinal cells, activates macrophages and microglia. Macrophages are large white blood
cells that form part of the immune system that engulf and digest cells, debris and foreign substances. Macrophages also play an important role in
modulating other parts of the immune system. Microglia are a type of tissue-residing macrophage located in the brain, spinal cord and retina.

Because pegcetacoplan both blocks the production of C3a and C5a and prevents the accumulation of C3 fragments on retinal cells through the

inhibition of C3, we believe that pegcetacoplan may control complement activation in the retinal environment to return it to its quiescent state. We do not
believe that selective inhibitors of the alternative pathway, which would only partially block the formation of C3b on the retinal cell surface, or C5
inhibitors, which cannot prevent C3b deposition on retinal cells, can cause the retinal environment to return to its quiescent state.

Current Therapies and Their Limitations

There are no therapies approved to treat GA. There are, however, therapies in development for GA including a number of product candidates in late

stages of clinical development.

Benefits of Our Approach

We believe pegcetacoplan, with its inhibition of complement activation at the level of C3 in the retinal environment, may provide the following

benefits:

•

•

Prevention or reduction of the rate of retinal cell death progression. We believe pegcetacoplan may mitigate or prevent retinal cell death in
GA. In our Phase 2 trial of pegcetacoplan in patients with GA, treatment with pegcetacoplan resulted in a significant reduction in the rate of
GA lesion growth over 12 months.

Potential application to all patients with GA independent of complement pathway causing disease progression. Pegcetacoplan, by targeting
C3, has been designed to inhibit all three principal complement activation pathways and may therefore be effective in a broad patient
population. We believe, based on the genetic marker and other data from our analysis of our Phase 2 trial, that the activity of pegcetacoplan
does not depend upon the activation of any particular complement pathway.

Clinical Development

We initiated the DERBY and OAKS Phase 3 clinical trials of pegcetacoplan in patients with GA following completion of our Phase 2 clinical trial in
patients with GA, which we refer to as the FILLY trial. In August 2017, we completed the primary endpoint analysis for the 12-month treatment period for
the Phase 2 FILLY trial and in February 2018 we completed the analysis of data from the six-month monitoring period from that trial. Prior to the FILLY
trial, we completed a Phase 1 clinical trial of pegcetacoplan in patients with wet AMD in 2016. In July 2018, we received fast track designation from the
FDA for pegcetacoplan in GA.

Phase 3 Clinical Trials

Our ongoing Phase 3 clinical program in GA consists of two 600-patient prospective, multicenter, randomized, double-masked, sham-injection

controlled trials (DERBY and OAKS) being conducted at 200 sites worldwide to assess the efficacy and safety of multiple intravitreal injections of
pegcetacoplan in patients with GA.  Both trials are fully enrolled and we expect to announce top-line data from these trials in the third quarter of 2021.

Patients in each Phase 3 trial receive a dose of 15 mg of pegcetacoplan injected intravitreally in a 0.1 cc volume, monthly or every other month for
24 months. In the sham-injection cohorts, patients receive a simulated injection. As with our Phase 2 clinical trial, the primary endpoint of each trial is the
change in total area of GA lesions in the study eye from baseline to month 12 compared to sham. The measurements of change in lesion size will be
analyzed at 12 months (primary endpoint, monthly group) and 24 months. We set statistical significance as a p-value of 0.05 or less, meaning that there is a
1 in 20 or less probability that the observed results occurred by chance. Patients who develop new onset exudation in the study eye will continue to be
treated with pegcetacoplan along with anti-VEGF injections, the current standard of care for wet AMD.  

The observation intervals in pivotal studies in AMD are typically 24 months in total duration to meet regulatory requirements for long-term safety
and to demonstrate durability of the treatment effect on anatomical and functional endpoints. However, based on our experience in the Phase 2 FILLY trial,
we believe that pegcetacoplan can show treatment effect at 12 months and we therefore plan to analyze the data after all patients have completed 12 months
of treatment in the trial in addition to a second assessment after 24 months of treatment. This design is in line with the recommendations of the FDA and
the EMA.

We are using a liquid formulation of pegcetacoplan in our Phase 3 trials instead of the freeze-dried formulation that we used in the Phase 2 FILLY

trial, which we believe may reduce the incidence of endophthalmitis.

In October 2018, we announced that we voluntarily implemented a pause in dosing in our Phase 3 clinical trials in patients with GA due to observed
cases of non-infectious inflammation in patients treated from a single manufacturing lot of pegcetacoplan intravitreal drug product. Four patients in the
Phase 3 GA program were treated with pegcetacoplan from this manufacturing lot and each patient developed non-infectious inflammation. Inflammation
in all patients completely resolved. We reviewed these events with the data safety monitoring board for our GA trials, conducted a series of non-human
studies  and  introduced  improvements  to  the  manufacturing  process.  Based  on  these  efforts,  we  believe  that  the  source  of  inflammation  resided  in
a contaminant or impurity in the active pharmaceutical ingredient. We resumed the trials in March 2019.

Phase 2 Clinical Trial

In the third quarter of 2015, we initiated a Phase 2 multicenter, randomized, single-masked, sham-controlled clinical trial of pegcetacoplan in
patients with GA, which we refer to as the FILLY trial, at more than 40 clinical sites, primarily located in the United States. We enrolled 246 patients in the
trial. Patients were randomized in a 2:2:1:1 manner to receive pegcetacoplan monthly, pegcetacoplan every other month, sham injection monthly or sham
injection every other month. Patients in the pegcetacoplan arms received a dose of 15 mg of pegcetacoplan injected intravitreally in a 0.1 cc volume,
monthly or every other month for 12 months followed by six months of monitoring without treatment. In the sham-injection cohorts, patients receive a
simulated injection. Study eyes received up to 13 injections in the monthly arm, and up to seven injections in the every other month arm. Eyes were
evaluated for GA at the end of months two, six, 12 and 18.

We conducted this trial to assess the safety, tolerability, pharmacokinetics, or PK, and evidence of activity of multiple intravitreal injections of
pegcetacoplan in patients with GA in at least one eye. The primary efficacy endpoint was change in the square root of GA lesion size from baseline to
month 12 in each treatment arm when compared to sham in the modified intent to treat population, which included 84 patients receiving administration of
pegcetacoplan every month, 78 patients receiving administration of pegcetacoplan every other month and 80 patients in the group receiving sham
injections. The primary safety endpoint was the number and severity of local and systemic treatment emergent adverse events. The trial was monitored by a
safety monitoring committee.

We announced 12-month results of the Phase 2 trial in August 2017. After 12 months, patients treated monthly with pegcetacoplan showed a 29%

reduction in the rate of GA lesion growth compared to sham, with a p-value of 0.008, and patients treated every other month showed a 20% reduction
compared to sham, with a p-value of 0.067. The rate of GA lesion growth in the

9

sham was consistent with the rate of lesion growth in patients with GA in third-party historical studies. These data are shown in the figure below.

EOM = Every other month

We set statistical significance as a p-value of 0.1 or less, meaning that there is a 1-in-10 or less statistical probability that the observed results

occurred by chance rather than as a result of a treatment effect. Because the p-value of these results was less than 0.1, they are statistically significant.

After the 12-month treatment period, patients were monitored for a further six months without treatment. During the monitoring period, the GA

lesions in the previously treated groups grew at a rate similar to sham but the treatment effect was maintained for the full 18 months. Patients who received
monthly pegcetacoplan, and for whom images were available at 12 and 18 months showed a 12% reduction in the growth rate of lesions over the six-month
monitoring period compared to sham, while patients who received every other month administration of pegcetacoplan showed a 9% reduction in the growth
rate of lesions over the six-month monitoring period compared to sham. These differences are not considered to be statistically significant. In the modified
intent to treat population over the full 18-month period, patients who received monthly pegcetacoplan showed a 20% reduction in the growth rate of lesions
over the full 18-month period compared to sham, while patients who received every other month administration of pegcetacoplan showed a 16% reduction
in the growth rate of lesions over the full 18-month period compared to sham.

The most frequently reported adverse events in the trial were associated with the injection procedure in the study eye. These adverse events included
two cases of confirmed endophthalmitis and one case of presumed endophthalmitis where the culture tested negative for bacterial growth. In the latter case,
the patient fully recovered visual acuity. In our Phase 2 trial, we observed an incidence rate of endophthalmitis of 0.21% per injection.

In addition, during the 12-month treatment period and the six-month monitoring period, we observed a higher incidence of new onset exudation in
the study eyes treated with pegcetacoplan as compared to sham, predominantly in patients with a history of wet AMD in the fellow eye. Specifically, we
observed that, after the 12-month treatment period and the six-month monitoring period, 18 patients (21%) receiving administration of pegcetacoplan every
month and seven patients (9%) receiving administration of pegcetacoplan every other month showed new onset exudation in the study eye, as compared to
one patient (1%) in the sham group.

Patients who experienced new onset exudation in the study eye were discontinued from treatment with pegcetacoplan and, in all but one case,

treated with standard of care anti-VEGF injections under supervision. There was no meaningful negative impact on visual acuity resulting from the new
onset exudations.

Phase 1b Clinical Trial in Low Vision Geography Atrophy

We are conducting a Phase 1b clinical trial to evaluate the safety of monthly intravitreal treatments with pegcetacoplan in 12 patients with bilateral
GA secondary to AMD and with low vision, which we initiated in September 2018.  Patients are dosed monthly with pegcetacoplan in one eye using the
fellow eye as an untreated control. In April 2020, we reported results in patients demonstrating a trend in reduced GA lesion growth in treated eyes versus
the lesion growth in untreated fellow eyes. In October 2020, we reported data from an 18-month post hoc analysis based on the seven study patients for
whom data were available for at least 18 months. In this population, the growth rate of GA lesions in the treated eye was on average 52% (mean square
root) slower than the untreated fellow eye (p=0.01). It has been shown in third-party studies that lesions in both eyes tend to grow at the same rate in

10

 
patients with bilateral GA.  Of the 12 enrolled patients, there were no reported cases of inflammation and one patient (8%) developed new-onset exudation
at month 12.

Phase 1b/2 Clinical Trial in Wet AMD

We conducted a Phase 1b/2, multi-center, open label clinical trial to evaluate the safety of intravitreal pegcetacoplan therapy when administered in

parallel with anti-VEGF treatments in patients with wet AMD in the study eye in the second quarter of 2018.  As with our Phase 3 program in GA, we
voluntarily implemented a pause in our Phase 1b/2 trial of pegcetacoplan in patients with wet AMD in October 2018. We discontinued the Phase 1b/2 trial
of pegcetacoplan in patients with wet AMD.

Phase 1 Clinical Trial

We conducted a Phase 1 open label, ascending single-dose clinical trial of pegcetacoplan administered by intravitreal injection in patients with wet

AMD who were receiving anti-VEGF therapy. We conducted the trial at multiple clinical sites both within and outside the United States to assess safety,
tolerability and PK of pegcetacoplan. In this trial, patients received a single dose of pegcetacoplan by intravitreal injection followed by 113 days of
monitoring. We enrolled eighteen patients in the trial, in three cohorts, at doses of 5 mg (3 patients), 10 mg (3 patients) and 20 mg (12 patients) of
pegcetacoplan. Pegcetacoplan was well tolerated, and no serious adverse events were reported. Based on the results, we determined to evaluate a dose of 15
mg in our Phase 2 trial.

Preclinical Studies

We have conducted preclinical studies in monkeys to assess the safety of pegcetacoplan injected intravitreally. A full toxicological review, including

histopathological examinations of both eyes and of multiple additional tissues from each monkey revealed no evidence of pegcetacoplan -related toxicity
changes at any of the doses tested.

Systemic Pegcetacoplan

We and Sobi plan to jointly advance the clinical development of systemic pegcetacoplan in five parallel registrational programs across
hematology, nephrology, and neurology. These include new registrational programs in CAD and HSCT-TMA. We will lead clinical development for
PNH, C3G/IC-MPGN and ALS, and Sobi will lead development activities for a Phase 3 trial in CAD and a Phase 2 trial in HSCT-TMA, both planned to
start in 2021.

Paroxysmal Nocturnal Hemoglobinuria

Background

PNH is a rare, chronic, debilitating blood disorder that is most frequently acquired in early adulthood and usually continues throughout the life of

the patient. Some of the prominent symptoms of PNH include severe anemia, a condition that results from having too few red blood cells, severe abdominal
pain, severe headaches, back pain, excessive weakness, fatigue and recurrent infections. If not treated, PNH results in the death of approximately 35% of
affected individuals within five years of diagnosis and 50% of affected individuals within ten years of diagnosis, primarily due to the formation of life-
threatening blood clots inside the blood vessels, or thrombosis. Based on prevalence data published in an abstract in a peer-reviewed journal, we estimate
that there are approximately 4,700 patients with PNH in the United States and approximately15,000 patients with PNH worldwide.

PNH is caused by the presence of mutant stem cells in the bone marrow that lack important proteins on their surface that protect against activation

of the complement system. In patients with PNH, an autoimmune response targets and eliminates normal stem cells, enabling mutant cells to become
dominant in the bone marrow. These mutant stem cells lead to mutant platelets and red blood cells that, unlike normal cells, are overly susceptible to
activation or destruction by the complement system. Mutant platelets, activated by the membrane attack complex, increase the risk of thrombosis, which is
the leading cause of mortality in patients with PNH. Mutant red blood cells are susceptible to destruction by intravascular and extravascular hemolysis.
Intravascular hemolysis, which involves the destruction of blood cells within the blood vessels, is caused by the formation of the membrane attack complex
on the surface of red blood cells causing them to rupture. Intravascular hemolysis causes severe anemia and contributes to the risk of thrombosis.
Extravascular hemolysis, which involves the destruction of blood cells outside the blood vessels, is caused by C3-related opsonization on red blood cells
leading to removal of the cells from the blood stream by the liver and the spleen. Extravascular hemolysis further contributes to severe anemia and
transfusion dependency in patients with PNH.

Current Therapies and Their Limitations

Eculizumab, marketed as Soliris, and ravulizumab, marketed as Ultomiris, both by Alexion Pharmaceuticals, Inc., or Alexion are the only therapies

that have been approved for the treatment of PNH. Eculizumab, which is administered every two weeks

11

intravenously, or directly into the veins, is designed to treat PNH by targeting C5 and preventing the formation of the membrane attack complex and
intravascular hemolysis. Many patients with PNH on treatment with eculizumab continue to be anemic. Ravulizumab is administered intravenously every
week and subcutaneously once per week and is designed to have a longer half-life and greater inhibition of C5 than eculizumab. Ravulizumab was tested in
two Phase 3 non-inferiority trials with eculizumab and was found to be non-inferior to eculizumab.

Retrospective third-party studies have reported that up to 70% of patients with PNH who are on treatment with eculizumab remained anemic and up
to 36% of patients on eculizumab continued to require at least one transfusion per year. In these studies, 100% of patients with PNH on eculizumab showed
evidence of C3-related opsonization on their red blood cells. We believe that uncontrolled extravascular hemolysis is responsible in part for these
continuing complications.

Benefits of Our Approach

We believe that, because pegcetacoplan inhibits complement activation at the level of C3, pegcetacoplan may provide the following benefits in

controlling PNH:

•

•

•

Prevention of intravascular hemolysis and its consequences. Pegcetacoplan may prevent the formation of the membrane attack complex on
blood cells and may thereby prevent the activation of mutant platelets and intravascular hemolysis, thus reducing the risk of thrombosis, the
leading cause of mortality in PNH, as well as reducing anemia.

Prevention of extravascular hemolysis and its consequences. Pegcetacoplan may prevent C3b opsonization, on blood cells, and may thereby
prevent extravascular hemolysis, further reducing anemia and transfusion dependency in patients with PNH.

Ease and convenience of use. We believe that the ability to self-administer pegcetacoplan by subcutaneous injection on a regular basis could
improve the quality of life for patients with PNH by eliminating the need to travel to a health care facility for intravenous treatment.

Regulatory Matters

We submitted an NDA to the FDA and an MAA to the EMA for pegcetacoplan for the treatment of PNH in September 2020. The FDA accepted the

NDA and set the PDUFA target action date for May 14, 2021.  The EMA validated the MAA in October 2020, with the potential for a European
Commission decision on the MAA in the second half of 2021.  

In April 2014, we received orphan drug designation from the FDA for pegcetacoplan for PNH. In February 2019 we received fast track designation
from the FDA for pegcetacoplan for patients with PNH, which superseded the fast track designation we received in December 2016 for pegcetacoplan for
the subset of patients with PNH who continue to require transfusions despite receiving therapy with eculizumab.

Clinical Development

If we are able to obtain marketing approval for pegcetacoplan for PNH, we plan to allow PNH patients on treatment with eculizumab to assess the

benefit of pegcetacoplan in co-treatment with eculizumab for a limited time, before deciding to switch to pegcetacoplan monotherapy or to revert to
eculizumab monotherapy.

If pegcetacoplan is approved for the treatment of patients with PNH, we believe that pegcetacoplan could be a best-in-class therapy for PNH,
differentiated by mechanism, and that pegcetacoplan has the potential to significantly increase the quality of life of patients with PNH as compared to the
current standard of care.

Phase 3 Clinical Trial - PEGASUS

We initiated the Phase 3 PEGASUS trial in patients in June 2018. The PEGASUS trial was an 80-patient randomized head-to-head trial comparing

pegcetacoplan monotherapy to eculizumab monotherapy in patients with PNH currently on treatment with eculizumab who have a hemoglobin level of less
than 10.5 g/dL, regarding of eculizumab dose or transfusion history. The primary efficacy endpoint of the trial was the change in hemoglobin level from
baseline at week 16.

The treatment period of the trial consisted of three parts: a four-week run-in period, a 16-week randomized treatment period and a 32-week open-

label pegcetacoplan only period. During the run-in period, all patients received twice-weekly subcutaneous doses of 1,080 mg of pegcetacoplan in addition
to patients’ then current dose of eculizumab. The run-in period was designed to provide patients with sufficient plasma concentration of pegcetacoplan to
provide for what we expected to be adequate complement inhibition before withdrawing eculizumab. Following completion of the run-in period, patients
received either 1,080 mg of pegcetacoplan twice per week or their current dose of eculizumab through the duration of the 16-week randomized treatment
period. Following completion

12

 
 
 
of the randomized treatment period with either pegcetacoplan monotherapy or eculizumab monotherapy, all 80 patients had the option to receive
pegcetacoplan monotherapy for 32 weeks in an open-label treatment period.

In January 2020, we announced top-line data from the PEGASUS trial that showed that pegcetacoplan met the primary efficacy endpoint,

demonstrating superiority to eculizumab with a statistically significant improvement in adjusted means of 3.8 g/dL of hemoglobin at week 16 (p < 0.0001).
At week 16, pegcetacoplan-treated patients (n = 41) had an adjusted mean hemoglobin increase of 2.4 g/dL from a baseline of 8.7 g/dL, compared to
eculizumab-treated patients (n = 39) who had a change of -1.5 g/dL from a baseline of 8.7 g/dL. Additionally, pegcetacoplan showed promising results in
key secondary endpoints. Pegcetacoplan met non-inferiority on transfusion avoidance and absolute reticulocyte count. Pegcetacoplan did not meet pre-
specified criteria for non-inferiority on mean LDH levels. Pegcetacoplan showed positive trends on LDH and fatigue as measured by the FACIT-fatigue
score. The statistical analysis plan for the PEGASUS trial provided for use of the mixed model—repeated measures (MMRM) method. To avoid the effect
of transfusions in hemoglobin levels during the 16-week randomization period of the trial, if a patient received a transfusion during the 16-
week randomization period, any measurements after the first transfusion were censored from the data used in the MMRM analysis. The treatment effects
using observed data from the trial, which included all post-transfusion measurements, were consistent with and supportive of the reported results from the
MMRM analysis.

All patients who completed the 16 week randomization period in both groups (77/80) entered the 32-week open-label pegcetacoplan treatment
period.  At week 48, patients treated with pegcetacoplan during the 16 week randomization period and through the 32 week open-label period sustained
increases in hemoglobin levels, with a mean improvement from baseline of 2.7 g/dL, equal to the 2.7 g/dL mean increase seen at week 16 in the same
patients. Additionally, patients treated with eculizumab in the randomized period who switched to pegcetacoplan during the open-label period
experienced sustained improvements in hemoglobin and other hematological and clinical measures, similar to patients treated with pegcetacoplan
monotherapy during the randomized controlled period.  In addition to a sustained improvement in hemoglobin, the pegcetacoplan-treated patients group
maintained improvements across key secondary endpoints. Throughout the 48-week study, 73% of patients treated with pegcetacoplan during the
randomized period remained transfusion free. For comparison, 25% of patients were transfusion free over the year prior to entering the PEGASUS study
while on treatment with eculizumab. Improvements across additional markers of disease, such as reticulocyte count, lactate dehydrogenase, or LDH,
levels, and the FACIT-fatigue scores, were observed in both groups at week 48 after 32 weeks of open-label treatment with pegcetacoplan.

 In the PEGASUS trial, the safety profile of pegcetacoplan was comparable to eculizumab and consistent with previously reported data.   After the
48-week study period, twenty-four of 80 pegcetacoplan monotherapy-treated patients (30%) experienced a serious adverse event (SAE).  Five of the SAEs
(6%) were assessed to be possibly related to study treatment. No cases of meningitis were reported. One death was reported due to COVID-19 and was
unrelated to study treatment. The most common adverse events (AEs) reported throughout the study were injection site reactions (36%), hemolysis (24%),
and diarrhea (21%). Twelve out of 80 patients (15%) discontinued due to adverse events, with five discontinuations due to hemolysis. Sixty-four of the 67
patients (96%) who completed the open-label period opted to enter the extension study.

 Phase 3 Clinical Trial – PRINCE

We initiated the Phase 3 PRINCE trial in September 2019. The PRINCE trial is a 54-patient randomized, multicenter, open-label trial to evaluate the

efficacy of pegcetacoplan in treatment-naïve PNH patients. The primary endpoints are avoidance of a greater than 1 g/dL decrease in hemoglobin level
from baseline in the absence of transfusion through week 26 and reduction in LDH level from baseline to week 26, in patients with PNH who are currently
not being treated with complement inhibitors. Secondary endpoints include hemoglobin response (defined as an increase in hemoglobin levels greater than
or equal to 1 g/dL), change in absolute reticulocyte count, change in hemoglobin levels, number of packed red blood cells transfused, change in FACIT
score, hemoglobin normalization and LDH normalization. This trial is fully enrolled and we expect to present top-line data in the second quarter of 2021.

Phase 1b Clinical Trials – PHAROAH and PADDOCK

Prior to commencing our two Phase 3 trials, we conducted two clinical trials of pegcetacoplan as part of our PNH program: a Phase 1b clinical trial

(PHAROAH) in patients with PNH being treated with eculizumab, which has concluded, and a Phase 1b clinical trial (PADDOCK) in treatment-naïve
patients. These trials were designed to assess safety and tolerability and whether pegcetacoplan has the potential to control PNH. In these trials, we
measured hemoglobin levels, which are significantly lower in patients with PNH, whether or not treated with eculizumab, and blood reticulocyte count,
which is an indicator of overall hemolysis (both intravascular and extravascular) in patients on eculizumab. We also measured intravascular hemolysis
based on LDH levels, which can be ten times higher than normal in patients with PNH, bilirubin, which is a breakdown product of hemoglobin and may be
higher in patients who experience hemolysis, and the clonal distributions of normal red blood cells and mutant red blood cells unprotected from the
membrane attack complex.

PHAROAH was a Phase 1b open-label, single and multiple ascending dose clinical trial of pegcetacoplan in patients with PNH who are receiving

eculizumab, conducted at multiple clinical sites in the United States. In the PHAROAH trial, doses of pegcetacoplan

13

were administered by subcutaneous injection to patients with PNH who were concurrently being treated with eculizumab at varying doses according to the
treating physicians’ recommendations. We treated a total of nine patients in the PHAROAH trial. Pegcetacoplan was generally well tolerated by the patients
in the trial with 12 serious adverse events reported across three patients. Only one of these serious adverse events was noted as possibly related to the
administration of pegcetacoplan. We initiated this trial in February 2015 and the last patient transitioned in October 2018 into a long-term extension study
that we are conducting.

PADDOCK was a Phase 1b open-label clinical trial of pegcetacoplan in treatment-naïve patients with PNH that we initiated in December 2015 and

conducted this trial at multiple clinical sites outside of the United States. In the PADDOCK trial, doses of pegcetacoplan were initially administered by
subcutaneous injection during the treatment period. We treated a total of 22 patients in the PADDOCK trial.  Pegcetacoplan had been generally well
tolerated in these patients with 13 serious adverse events reported across seven patients.  Only one of these serious adverse events was noted as possibly
related to administration of pegcetacoplan.

Long-Term Extension Study

We are conducting a long-term extension study of pegcetacoplan in patients with PNH who participated in previous clinical trials with
pegcetacoplan. This study is an open label, non-randomized, multi-center study to evaluate the long-term safety and efficacy of pegcetacoplan in the
treatment of PNH with dosing for a longer period and at doses of 1,080 mg given either twice a week or every three days. We expect to continue the
extension study until pegcetacoplan becomes commercially available in the subject’s participating country, or until the development program for
pegcetacoplan in patients with PNH is terminated.

Phase 1 Clinical Trials—Single and Multiple Ascending Dose in Healthy Volunteers

We have completed both single ascending and multiple ascending dose Phase 1 randomized, double-blind, placebo-controlled clinical trials of

pegcetacoplan in a total of 55 healthy volunteers. We conducted the trials at a single site in Australia to assess the safety, tolerability, PK and
pharmacodynamics, or PD, of pegcetacoplan. Pegcetacoplan was well tolerated in both trials with no serious adverse events reported, and the PK of
pegcetacoplan in humans was in line with our expectations derived from preclinical data, with little inter-subject variability observed. In both trials, we
observed a dose-dependent increase in C3 that is indicative of pegcetacoplan binding to C3.

Supporting Clinical Trials and Studies

We conducted a Phase 1 trial to assess the safety and tolerability of pegcetacoplan in patients with renal impairment. The study included one cohort

of eight patients with severe renal impairment and a second cohort of eight control patients and will evaluate various PK endpoints, in addition to safety
and tolerability endpoints. No significant difference in PK parameters was noted.

We conducted a Phase 1 trial to determine the safety, PK and PD of twice-weekly and once-weekly subcutaneous administration of pegcetacoplan in

healthy volunteers. We evaluated whether less frequent administration provides comparable PK and PD profiles to daily subcutaneous administration and
may enable less frequent dosing in upcoming clinical trials. We established the dosing regimen in PEGASUS and PRINCE based on this trial.

We conducted a Phase 1 trial to determine the safety, PK and PD of pegcetacoplan in healthy volunteers of Japanese descent. We evaluated whether

pegcetacoplan will have comparable PK and PD profiles in this population. No significant difference in PK parameters was noted.

Preclinical Studies

We have conducted numerous preclinical studies of pegcetacoplan in animals and in laboratory samples to assess the safety of pegcetacoplan,

including repeat-dose subcutaneous and intravenous toxicity studies of pegcetacoplan in rats, rabbits and monkeys for durations of up to nine months. In
these studies, there were no significant macroscopically observable or clinical pathology drug-related changes in any species at any of the doses tested.
Similarly, there was no evidence of a potential for adverse effects on myocardial conduction or cardiovascular and respiratory systems in either species, and
no genotoxicity potential was observed. In addition, no signs of infection were observed in any of the studies that we conducted. The main toxicity
observed at the highest doses tested was microscopic kidney damage, likely resulting from accumulation of pegcetacoplan in the kidney, which is one of
the organs we believe to be responsible for its clearance from the body.

While there is no animal model of PNH, pegcetacoplan inhibited both hemolysis of red blood cells by the membrane attack complex and C3

fragment deposition on the surface of these cells in preclinical studies that we conducted ex vivo on blood samples from patients with PNH.

Safety

In all trials of pegcetacoplan administered systemically by subcutaneous injection, we have monitored the safety of our targeting of C3 closely.

Individuals who lack functional levels of C3 or C5 have been shown to be susceptible to infection by certain bacterial species, including Neisseria
meningitidis in C5-deficient individuals and Neisseria meningitidis, Streptococcus pneumoniae and Haemophilus influenzae in C3-deficient individuals. As
a result, we vaccinate patients in these trials against these three pathogens, which we believe minimizes the risk of infection.

As of February 10, 2021, in our clinical trials of pegcetacoplan using subcutaneous administration in patients with PNH or healthy volunteers, a total

of 155 serious adverse events had been reported in 80 of the 279 subjects dosed with pegcetacoplan. Of these 155 serious adverse events, 15 were
considered to be at least possibly related to study medication by the investigator. None of these indicated any unexpected safety concerns.

Commercial and Medical Activities for PNH Launch

We are preparing for the launch of pegcetacoplan for patients with PNH in the United States if the FDA approves our NDA submission.  We have
built commercial and medical organizations focused on addressing the needs of patients at launch.  In particular, for PNH we have defined our marketing,
disease education, patient support and distribution strategies, identified primary and secondary payers representing a significant percentage of patients with
PNH, and have built sales and market access teams in preparation for a commercial launch.  

Our market access team is fully staffed and has engaged with primary and secondary payers representing a significant percentage of PNH patients.

We believe that our discussions with primary and secondary payers have yielded positive feedback on the clinical profile of pegcetacoplan. We plan to
implement a limited distribution specialty pharmacy model, which we believe will provide patients with a consistent, positive experience at the time of
treatment initiation and long-term assistance to the extent needed.

We have established ApellisAssist, a patient-focused program specifically designed to assist patients with onboarding, product training and ongoing

support with pegcetacoplan treatment, and we are building a care educator team to connect directly with PNH patients and their caregivers to provide
education and training on the use of pegcetacoplan.

We plan to deploy our sales team to cover the health care professionals and key treatment centers, focusing on health care professionals who have

patients that continue to experience breakthrough hemolysis, have persistently low hemoglobin, high fatigue, and require transfusions despite being on C5
inhibitors.

We have initiated the commercial manufacturing process for our commercial drug product, obtained required regulatory licenses and executed
agreements to establish our warehousing, logistics and distribution networks.  Under our collaboration agreement, Sobi will conduct the commercial launch
of pegcetacoplan for patients with PNH in jurisdictions outside the United States.  

We are developing a custom, on-body drug delivery system that would enable patients to self-administer pegcetacoplan through subcutaneous
infusion. While this device is in development, we plan to use one or more commercially available ambulatory infusion pumps in our ongoing and planned
clinical trials and for our commercial launch of pegcetacoplan as a treatment for PNH.

Our medical affairs team has engaged with top treating physicians through our virtual presence at medical meetings and in-person engagements

when appropriate. In December 2020, we participated in the virtual American Hematology Society, or ASH, annual meeting, and we launched an Apellis
medical affairs microsite where the ASH data are available for U.S. healthcare providers. We will continue to leverage this platform for future medical
congresses. We have initiated an early access program and have already established multiple U.S. sites for patients.   Sobi will conduct medical affairs
activities for systemic pegcetacoplan outside the United States.

C3 Glomerulopathy and Immune Complex Membranoproliferative Glomerulonephritis

C3G and IC-MPGN are rare, debilitating kidney diseases that affect approximately 18,000 people in the United States and Europe. There are no
approved therapies for the diseases, and symptoms include blood in the urine, dark foamy urine due to the presence of protein, swelling, and high blood
pressure.  Approximately 50% of people living with IC-MPGN and C3G ultimately suffer kidney failure within five to 10 years of diagnosis. Although
IC-MPGN is considered a distinct disease from C3G, the underlying cause and progression of the two diseases are remarkably similar and include
overactivation of the complement cascade, with excessive accumulation of C3 breakdown products in the kidney causing inflammation and damage to the
organ.  There are no medicines currently approved for C3G or IC-MPGN. Pegcetacoplan is designed to prevent C3 activation, and as such, we believe it

15

has the potential to prevent further deposition of C3 activation products in the glomeruli, which may protect the kidney from further injury.

In February 2018, we initiated a Phase 2 clinical trial of pegcetacoplan in biopsy-proven C3G and other glomerular diseases in which complement

has been implicated, including IgA nephropathy, primary membranous nephropathy and lupus nephritis, to evaluate the safety and biologic activity of
pegcetacoplan in patients with these glomerular diseases. We refer to this trial as the DISCOVERY trial. Initially each patient received once daily
subcutaneous infusions of up to 360 mg of pegcetacoplan for one year but patients could elect to receive twice weekly subcutaneous infusions of 1080 mg
after week 24. The primary efficacy endpoint was the reduction in proteinuria, an important market of kidney damage, from baseline to week 48 as
quantified by protein-to-creatinine ratio, or uPCR. Based on the scientific literature as well as the underlying pathophysiology of the disease, we believe
that a substantial change in proteinuria is reasonably likely to predict a clinical benefit in all four glomerular diseases. Secondary endpoints included
analysis of serum C3 and estimated glomerular filtration rate.  

In October 2020, we reported data from the DISCOVERY trial in five C3G patients treated with pegcetacoplan for 48 weeks.  In those patients,
mean (SE) proteinuria decreased from 3.48 (0.82) mg/mg at baseline to 0.93 (0.27) mg/mg at week 48, a decrease of 73.3%, as measured by 24-hour
uPCR. Importantly, this reduction in proteinuria was accompanied by a corresponding increase in mean serum albumin. Since albumin is the most
abundant protein in serum, its level increases when urinary protein losses are reduced. Other biomarkers improved, including an observed increase in
mean serum C3 and stabilization of renal function, as measured by mean serum creatinine. No serious or severe adverse events were reported, and
pegcetacoplan was well tolerated overall.

In October 2020, we initiated a registrational program in C3G and IC-MPGN beginning with a randomized, controlled Phase 2 trial in 12 patients
with post-transplant disease recurrence that focused on the histopathology of the kidneys. We refer to this trial as the NOBLE trial.  Trial participants are
randomized in a 3:1 ratio to receive pegcetacoplan or maintain standard of care for 12 weeks and then all patients in the study will receive pegcetacoplan
from week 13 to week 52. The primary endpoint of the study is the proportion of patients with reduction in C3c staining on renal biopsy after 12 weeks of
treatment with pegcetacoplan. Secondary endpoints include an evaluation of safety, the proportion of patients with reduction in C3c staining on renal
biopsy after 52 weeks of treatment, and the proportion of patients achieving at least a 50% reduction in proteinuria.  We expect to dose the first patient in
the NOBLE trial in the first half of 2021. We plan to begin a Phase 3 trial in patients with C3G and IC-MPGN in the second half of 2021 with reduction
in proteinuria as its primary endpoint.

We met with the FDA in October 2017 in a pre-IND meeting and submitted an IND to the FDA in November 2017. In December 2018, we received

orphan drug designation from the FDA for the treatment of C3G.

Amyotrophic Lateral Sclerosis

ALS is a devastating neurodegenerative disease that results in progressive muscle weakness and paralysis due to the death of nerve cells, called

motor neurons, in the brain and spinal cord.  The death of motor neurons leads to the progressive loss of voluntary muscle movement required for
speaking, walking, swallowing, and breathing.  In individuals with ALS, high levels of C3 are present at the neuromuscular junction where motor
neurons communicate directly to muscle cells. Numerous studies suggest that elevated levels of C3 present throughout the motor system of ALS patients
are likely to contribute to chronic neuroinflammation and the death of motor neurons. There are currently no approved treatments that stop or reverse the
progression of ALS, which impacts approximately 225,000 patients worldwide.

We initiated a randomized, double-blind, placebo-controlled, multicenter Phase 2 clinical trial designed to evaluate the efficacy and safety of

pegcetacoplan in approximately 200 adults with sporadic ALS. We refer to this trial as the MERIDIAN trial. Trial participants are randomized in a 2:1
ratio to receive pegcetacoplan or placebo while continuing to receive their existing standard of care treatment for ALS. After 52 weeks of blinded
treatment, all patients in the study will receive pegcetacoplan. To reduce the burden on people living with ALS and their caregivers, the study has been
designed to minimize the number of in-clinic visits, with approximately six clinic visits in the first year and four in the open-label second year.  The
primary endpoint of this trial is the Combined Assessment of Function and Survival (CAFS) rank scores at week 52. We treated the first patient in
MERIDIAN in November 2020 and expect to complete enrollment in MERIDIAN in the second half of 2021.

Cold Agglutinin Disease

CAD is a severe, chronic, rare blood disorder that impacts about 10,500 people across the United States and Europe.  People living with CAD

may suffer from chronic anemia, transfusion requirements, and an increased risk of life-threatening thrombotic events such as stroke. In people with
CAD, immunoglobin M (IgM) autoantibodies cause red blood cells to agglutinate, or clump together, at temperatures below 30oC or as a result of a
compromised immune system or infection This activates the complement cascade to destroy healthy red blood cells through extravascular and
intravascular hemolysis.  There is no FDA-approved drug

16

therapy specifically for CAD. The primary and secondary therapies, which include corticosteroids, splenectomy, alkylating agents and
immunosuppressive drugs, are associated with low response rates, relapses and clinically significant adverse effects.

We believe that C3 inhibition has the potential to prevent C3-related opsonization and extravascular hemolysis in patients with CAD, and that
inhibiting the complement system by targeting C3 may have the same impact, if not greater, as other complement pathway drugs in these diseases. In
collaboration with Sobi, we are developing pegcetacoplan as a monotherapy for CAD. In March 2018, we initiated a Phase 2 open label clinical trial of
pegcetacoplan administered by subcutaneous injection in patients with CAD, which we refer to as the PLAUDIT trial. In the PLAUDIT trial, doses of
pegcetacoplan were initially administered by subcutaneous injection during the treatment period, followed by a long-term extension period. We have
treated a total of 13 patients with CAD in the PLAUDIT trial. In December 2018, we announced interim data for the Phase 2 trial at the ASH Conference
and further interim data at the European Hematology Association Congress in June 2019. We observed that in the 10 patients with CAD who reached day
168:

70% showed a Hb increase of ≥ 2 g/dL, 40% had normalized Hb (≥ 12.0 g/dL) and 80% had Hb ≥ 11.0 g/dL at Day 168

•
• Mean Hb increased from 8.9 g/dL at baseline to 11.2 g/dL at Day 168, a 2.4 g/dL increase (normal Hb is 12 - 16 g/dL)
• Mean Functional Assessment of Chronic Illness Therapy (FACIT) Fatigue Score increased from 29.4 at baseline to 39.1 at Day 168, an

improvement of 9.7 points, where a clinically significant increase is 3 or more points

• Mean absolute reticulocyte count (ARC) decreased from 138.6 X 10⁹/L at baseline to 63.6 X 10⁹/L at Day 168 (normal ARC is 30 - 100 X

10⁹/L)

• Mean indirect bilirubin decreased from 1.9 mg/dL at baseline to 0.4 mg/dL at Day 168 (normal indirect bilirubin is 0.1 -0.75 mg/dL)
• Mean LDH decreased from 486.5 U/L at baseline to 183.2 U/L at Day 168 (normal LDH is 87 - 252 U/L)

Pegcetacoplan has been generally well tolerated in these patients in the PLAUDIT trial, with a safety profile similar to that of other studies of

systemic administration of pegcetacoplan.

Sobi will lead development activities for a Phase 3 trial in CAD, planned to start in 2021.

Hematopoietic Stem Cell Transplantation Thrombotic Microangiopathy

Hematopoietic stem cell transplantation thrombotic microangiopathy, or HSCT-TMA, is rare blood disease that can be a fatal complication of a

bone marrow transplant or HSCT. In HSCT-TMA, microscopic blood clots form in small blood vessels, leading to organ damage. The kidneys are
commonly affected, although any organ may be involved. HSCT-TMA occurs in up to 40% of HSCT recipients; every year, there are approximately
9,000 allogeneic transplants in the United States and approximately 18,000 in the European Union.  Excessive complement activation is a high-risk
feature in patients with HSCT-TMA, and C3 is believed to play a critical role in TMA based on proinflammatory and procoagulant properties of C3a and
C3b.

Sobi will lead development activities for a Phase 2 trial in HSCT-TMA, planned to start in 2021.

Pipeline

We are developing pegcetacoplan and other product candidates, including APL-9, targeting C3 through various routes of administration.  We plan to
conduct clinical trials of these compounds in additional complement-dependent indications.  We plan to advance three new product candidates into clinical
development by the end of 2022.

APL-9 is a C3 modulator designed to be intravenously administered for acute use.  In May 2020 we initiated a Phase 1/2 randomized, vehicle-
controlled clinical trial for APL-9 in 66 patients with respiratory failure including acute respiratory distress syndrome, or ARDS, secondary to COVID-19.
We hypothesize that complications of severe COVID-19 infections, including ARDS, are a consequence of complement mediated coagulation and
angiopathies.  We expect to report results from this trial in the second quarter of 2021. Additionally, we are developing APL-9 for the prevention of
complement immune system activation coincident with AAV vector administration for gene therapies and other indications.  We believe that targeted
control of C3 may prevent the C3-mediated immune response attack on AAV particles, yielding three important potential advantages. First, controlling C3
may significantly increase the efficiency of gene therapy delivery by protecting the AAV particles on their journey from the site of administration to the
target tissue. This may reduce the amount of particles needed to be used in gene therapies. Second, control of C3 may minimize the formation of anti-AAV
neutralizing antibodies that can complicate subsequent retreatment with the same AAV. Finally, by countering the rapid activation of C3 upon
administration of AAV particles, control of C3 may prevent inflammatory reactions that can lead to significant organ damage.

We have conducted a single ascending dose Phase 1 randomized, double-blind, placebo-controlled clinical trials of APL-9 in 20 healthy volunteers to

determine the safety, PK and PD of APL-9. In this trial, APL-9 was administered either as a single intravenous

17

 
 
 
 
 
 
dose infused over 30 minutes or as a slow bolus intravenous loading dose to provide rapid pharmacological complement inhibition followed by a
continuous intravenous infusion to maintain pharmacological levels of APL-9 for the desired duration. APL-9 demonstrated control of complement through
modulation of C3 within one hour of administration, that lasted up to 12 hours after the end of the infusion. Multiple doses tested achieved complete
suppression of the AH50 hemolytic activity. In this Phase I study, APL-9 was well tolerated with no serious adverse events reported. In the study,
complement activity resumed shortly after the termination of the intravenous infusion.

Collaboration and License Agreement with Sobi

In October 2020, we entered into a Collaboration and License Agreement with Sobi concerning the development and commercialization of

pegcetacoplan and specified other compstatin analogues or derivatives for use systemically or for local non-ophthalmic administration, or Licensed
Products. The agreement does not cover pegcetacoplan or other compstatin analogues or derivatives used for non-systemic ophthalmic administration or
APL-9.

Under the agreement, we granted Sobi an exclusive (subject to certain rights retained by us), sublicensable license under certain patent rights and

know-how to develop and commercialize Licensed Products in all countries outside of the United States.

We retained the right to commercialize Licensed Products in the United States, and, subject to specified limitations, to develop Licensed Products

worldwide for commercialization in the United States.

Under the agreement, we and Sobi have agreed to collaborate to develop Licensed Products for the treatment of PNH, CAD, HSCT-TMA, C3G, IC-
MPGN and ALS, or the “Initial Indications”, and any other indications subsequently agreed upon by the parties, for commercialization by or on our behalf
in the United States and by or on behalf of Sobi outside of the United States. If the parties do not agree to jointly pursue any development activities for the
Licensed Products (whether for an Initial Indication or otherwise), the party proposing to pursue such activities may conduct such activities at its sole
expense (with the non-proposing party having the right to obtain rights to the data generated by such development activities by paying a specified
percentage of that expense), subject to agreed-upon exceptions that limit each party’s unilateral development rights.

The initial development plan sets forth the initial development activities to be conducted by each of us and Sobi, with us bearing all costs incurred in

conducting the activities set forth in such initial development plan, as well as certain specified additional costs that are not included in the initial
development plan that may be incurred by the parties in developing Licensed Products for paroxysmal nocturnal hemoglobinuria in the European Union
and the United Kingdom.

Each party is obligated to use commercially reasonable efforts to complete the development obligations assigned to it in the development plan. We

are obligated to use commercially reasonable efforts to obtain regulatory approval from the FDA for a Licensed Product in each of the Initial Indications, to
obtain regulatory approval from the EMA for a Licensed Product in PNH and to assist Sobi to obtain other regulatory and reimbursement approvals for
Licensed Products outside of the United States. Sobi is obligated to use commercially reasonable efforts to develop and obtain regulatory approval for, and
to commercialize, Licensed Products for each of the Initial Indications in specified major markets.

We have agreed to supply to Sobi, pursuant to a supply agreement to be negotiated by the parties, Licensed Products for development and for
commercialization outside of the United States in accordance with the agreement. The agreement granted Sobi the right to perform or have performed drug
product manufacturing of Licensed Products for development and for commercialization outside the United States and to manufacture or have
manufactured drug substance under certain circumstances.

We and Sobi have formed several governance committees to oversee the development and manufacture, and to review and discuss the

commercialization, of Licensed Products.

We have agreed not to, directly or indirectly, alone or with or for any other person or entity, conduct any clinical development or commercialization

of APL-9 for any Initial Indication or any other indications subsequently agreed upon by the parties.

Under the terms of the agreement, Sobi paid an upfront payment of $250 million, and agreed to pay us up to an aggregate of $915 million upon the
achievement of specified one-time regulatory and commercial milestone events, and to reimburse us for up to $80 million in development costs. We will
also be entitled to receive tiered, double-digit royalties (ranging from high teens to high twenties) on sales of Licensed Products outside of the United
States, subject to customary deductions and third-party payment obligations, until the latest to occur of: (i) expiration of the last-to-expire of specified
licensed patent rights; (ii) expiration of regulatory exclusivity; and (iii) ten (10) years after the first commercial sale of the applicable Licensed Product, in
each case on a Licensed Product-by-Licensed Product and country-by-country basis. Under the agreement, we remain responsible for its license fee
obligations (including royalty obligations) to the Penn and for our payment obligations to SFJ.

18

Unless earlier terminated, the agreement will expire upon the expiration of the last royalty term for the last Licensed Product outside of the United

States. The agreement may be terminated in its entirety by Sobi upon 90 days’ prior written notice at any time after the earlier of (i) October 27, 2022 or (ii)
receipt of the first regulatory approval for the first Licensed Product in any of France, Germany, Italy, Spain, or the United Kingdom. Either party may,
subject to specified cure periods, terminate the agreement in its entirety in the event of the other party’s uncured material breach. In addition, we may,
subject to specified cure periods, terminate the agreement in any of China, Japan, Brazil, or Canada if Sobi materially breaches its obligation to use
commercially reasonable efforts to develop, obtain regulatory approval for, and commercialize a Licensed Product for paroxysmal nocturnal
hemoglobinuria and amyotrophic lateral sclerosis in such country. Either party may also terminate the agreement under specified circumstances relating to
the other party’s insolvency. We may terminate the agreement in the event Sobi or its specified affiliates or sublicensees challenges the validity, scope or
enforceability of the licensed patent rights under specified circumstances.

Intellectual Property

Our success depends in part on our ability to obtain and maintain proprietary protection for our product candidates, technology and know-how, to
operate without infringing the proprietary rights of others and to prevent others from infringing our proprietary rights. We seek to protect our proprietary
position in a variety of ways, including by pursuing patent protection in certain jurisdictions where it is available. For example, we file U.S. and certain
foreign patent applications related to our proprietary technology, inventions and improvements that are important to the development of our business. We
also rely on trade secrets, know-how, continuing technological innovation and in-licensing opportunities to develop and maintain our proprietary position.

Pegcetacoplan and APL-9 are analogs of the cyclic peptide compstatin, based on technologies that we have developed internally or have exclusively

licensed from the Trustees of the University of Pennsylvania, or Penn.

As of December 31, 2020, we own a total of 13 U.S. patents and 31 pending U.S. patent applications, including original filings, continuations and

divisional applications, as well as numerous foreign counterparts of many of these patents and patent applications. Our patents and patent applications
include families of US and foreign patent and patent applications relating, for example, to the composition of matter of certain compstatin analogs with a
prolonged in vivo half-life, including pegcetacoplan, and/or to methods of treatment and dosing regimens for treating particular complement-dependent
diseases. Patents in these families would expire in 2032 or 2033. Our patent applications also include families relating in part to particular doses and dosing
regimens for intravitreally or subcutaneously administered pegcetacoplan. Patents based on these applications would expire between 2036 and 2038.
Finally, the filings include certain U.S. and foreign patents and patent applications relating to methods of treating eye disorders associated with complement
activation, which we acquired in the acquisition of the assets of Potentia Pharmaceuticals, Inc., or Potentia. These acquired Potentia patent rights include
issued U.S. patents with claims to methods of treating AMD by administration of compstatin analogs and a granted European patent with claims to a class
of compstatin analogs for use in treatment of macular degeneration. These patents have terms that extend into 2026.

In addition to the technology that we developed internally, we hold exclusive licenses from Penn, including a license agreement with Penn that was

assigned to us in connection with our acquisition of the Potentia’s assets in September 2015. The intellectual property in-licensed under our two license
agreements with Penn includes four U.S. patents and numerous foreign counterparts, with claims granted or pending in Europe, Japan and elsewhere. These
licensed patent rights include issued patents with claims that recite a class of compounds generically covering our lead product candidates, pegcetacoplan
and APL-9, and that specifically recite the active component. These patents have terms that extend to 2026.

The term of individual patents depends upon the legal term for patents in the countries in which they are granted. In most countries, including the

United States, the patent term is generally 20 years from the earliest claimed filing date of a non-provisional patent application in the applicable country. In
the United States, a patent’s term may, in certain cases, be lengthened by patent term adjustment, which compensates a patentee for administrative delays
by the U.S. Patent and Trademark Office in examining and granting a patent or may be shortened if a patent is terminally disclaimed over a commonly
owned patent or a patent naming a common inventor and having an earlier expiration date. The Drug Price Competition and Patent Term Restoration Act of
1984, or the Hatch-Waxman Act, permits a patent term extension of up to five years beyond the expiration date of a U.S. patent as partial compensation for
the length of time the drug is under regulatory review while the patent is in force. A patent term extension cannot extend the remaining term of a patent
beyond a total of 14 years from the date of product approval, only one patent applicable to each regulatory review period may be extended and only those
claims covering the approved drug, a method for using it or a method for manufacturing it may be extended.

Similar provisions are available in the European Union and certain other foreign jurisdictions to extend the term of a patent that covers an approved
drug. In the future, if and when our product candidates, including pegcetacoplan, receive approval by the FDA or foreign regulatory authorities, we expect
to apply for patent term extensions on issued patents covering those products, depending upon the length of the clinical trials for each drug and other
factors. Expiration dates referred to above are without regard to potential patent term adjustment or extension or other market exclusivity that may be
available to us.

19

We granted worldwide rights to use and license the intellectual property that we hold with respect to pegcetacoplan and APL-9 to our wholly owned

subsidiaries, APL DEL Holdings, LLC and Apellis Switzerland GmbH.   Our wholly owned subsidiary, Apellis Australia Pty Ltd., holds certain rights to
use our intellectual property to manage our clinical trials in Australia and exclusive rights to distribute our product with respect to specific indications
within Australia and certain other territories. We granted Sobi an exclusive (subject to certain retained rights), sublicensable license of certain patent rights
and know-how to develop and commercialize pegcetacoplan for non-ophthalmological indications in all countries outside of the United States.

We may rely, in some circumstances, on trade secrets to protect our technology. However, trade secrets can be difficult to protect. We seek to protect

our proprietary technology and processes, in part, by confidentiality agreements with our employees, consultants, scientific advisors and contractors. We
also seek to preserve the integrity and confidentiality of our data and trade secrets by maintaining physical security of our premises and physical and
electronic security of our information technology systems.

Patent License Agreement with The Trustees of the University of Pennsylvania (Non-ophthalmic Fields of Use)

In March 2008, Apellis AG entered into an agreement with Penn for an exclusive worldwide license, under specified patent rights controlled by
Penn, to develop and commercialize products covered by the licensed patent rights for all fields except the treatment of ophthalmic indications. This license
was assigned to us in 2010 in connection with our acquisition of Apellis AG, and we have the right to grant sublicenses under this license.

The patent rights licensed to us by Penn include patents with claims that recite a class of compounds generically covering our lead product

candidates, pegcetacoplan and APL-9, and specifically recite the active component.

In exchange for the rights licensed from Penn, Apellis AG transferred to Penn shares of Potentia common stock that it had purchased from Potentia
with a $250,000 promissory note in 2008. In 2010, Apellis AG assigned its Penn license to us together with the promissory note. We repaid the promissory
note in full in 2013.

Under the license agreement, we are obligated to make a $100,000 annual license maintenance payment to Penn until the first commercial sale of a

licensed product, some of which may become creditable against milestone payments under specified circumstances. We may also become obligated to
make payments to Penn aggregating up to $1,650,000 based on achieving specified development and regulatory approval milestones and up to $2,500,000
based on achieving specified annual sales milestones with respect to each of the first two licensed products, and to pay low single-digit royalties to Penn
based on net sales of each licensed product by us and our affiliates and sublicensees and specified minimum quarterly royalty thresholds. In addition, we
are obligated to pay Penn a specified portion of income we receive from sublicensees.

In 2018 we made payments of $375,000, net of a credit for the annual license maintenance payment, for the achievement of milestones under this

agreement.

In January 2021 we made payments of $25,050,000 as sublicenses fee under this agreement with respect to the Sobi collaboration and certain other

strategic collaborations.

Our royalty obligation with respect to each licensed product in a country extends until the later of the expiration of the last-to-expire patent licensed

from Penn covering the licensed product in the country or the expiration of a specified number of years after the first commercial sale of the licensed
product in the country.

We have the right to grant sublicenses under the license.

We also are obligated to use commercially reasonable efforts to develop licensed products in accordance with a development plan, which we will
update annually, and a development milestone timetable specified in the agreement and to use commercially reasonable efforts to commercialize licensed
products.

Penn has the right to terminate the agreement if we breach the agreement and fail to cure our breach within specified cure periods or in the event of

specified bankruptcy, insolvency and liquidation events. We have the right to terminate the agreement for our convenience at any time on 60 days’ notice to
Penn.

Amended and Restated Patent License Agreement with The Trustees of the University of Pennsylvania (Ophthalmic Field of Use)

At the same time that it entered into the agreement with Apellis AG, Penn licensed rights to the same portfolio of cases to Potentia, to develop and
commercialize products covered by the licensed patent rights for the treatment of ophthalmic indications. In September 2015, Potentia assigned the license
agreement between Potentia and Penn to us in connection with our acquisition of the assets of Potentia pursuant to an asset purchase agreement with
Potentia.

20

Upon Potentia’s assignment of the license to us, we became the licensee and are obligated to make a $100,000 annual license maintenance payment

to Penn until the first commercial sale of a licensed product. We also became obligated to make payments to Penn aggregating up to $3,200,000 based on
achieving specified development and regulatory approval milestones and up to $5,000,000 based on achieving specified annual sales milestones with
respect to each licensed product, and to pay low single-digit royalties to Penn based on net sales of each licensed product by us and our affiliates and
sublicensees and specified minimum quarterly royalty thresholds. In addition, we are obligated to pay Penn a specified portion of income we receive from
sublicensees.

In 2018 we made payments of $650,000, net of a credit for the annual license maintenance payment, for the achievement of milestones under this

agreement.

Our royalty obligation with respect to each licensed product in a country will extend until the later of the expiration of the last-to-expire patent
licensed from Penn covering the licensed product in the country or the tenth anniversary of the first commercial sale of the licensed product in the country.

We have the right to grant sublicenses under the license.

We also are obligated to use commercially reasonable efforts to develop licensed products in accordance with a development plan, which we will
update annually, and a development milestone timetable specified in the agreement and to use commercially reasonable efforts to commercialize licensed
products.

Penn has the right to terminate the agreement if we breach the agreement and fail to cure our breach within specified cure periods or in the event of

specified bankruptcy, insolvency and liquidation events. We have the right to terminate the agreement for our convenience at any time on 60 days’ notice to
Penn.

Competition

The biotechnology and pharmaceutical industries are characterized by rapidly advancing technologies, intense competition and a strong emphasis on

proprietary products. While we believe that our technologies, knowledge, experience and scientific resources provide us with competitive advantages, we
face potential competition from many different sources, including major pharmaceutical, specialty pharmaceutical and biotechnology companies, academic
institutions and governmental agencies and public and private research institutions. Any product candidates that we successfully develop and
commercialize will compete with existing therapies and new therapies that may become available in the future.

There are a number of currently marketed products and product candidates in preclinical research and clinical development by third parties to treat

the various diseases that we are targeting. In general, these products and product candidates can be categorized based on their proposed mechanisms of
action. The mechanisms of action for these product candidates include inflammation suppression by agents such as complement inhibitors and
corticosteroids, as well as immune modulators, visual cycle modulators, anti-amyloid agents, antioxidants, neuroprotectants, cell and gene therapies and
vascular and interstitial tissue remodeling agents.

If our lead product candidate is approved for the indications for which we are currently undertaking or planning clinical trials, it will compete with

the products and product candidates discussed below.  

GA. There are currently no approved treatments for GA. We are aware that there are a number of companies that are actively developing product

candidates for the treatment of GA, including the following product candidates that are in clinical development: ANX007, a C1q inhibitor being developed
by Annexon Biosciences;  GT005, a CFI expression inhibitor being developed by Gyroscope Therapeutics in Phase 2 clinical trials IONIS-FB-L(RX), a
complement factor B inhibitor being developed by Genentech/Ionis in Phase 2 clinical trials; Zimura, a C5 inhibitor being developed by Iveric bio
(formerly known as Ophthotech Corporation) in Phase 2/3 clinical trials; HMR59, an intravitreal gene therapy being developed by Janssen Pharmaceutical
(after acquisition from Hemera Biosciences) in Phase 2 clinical trials;  NGM621, a C3 inhibitor being developed by NGM Bio, in Phase 2 clinical
trials;  and other product candidates that do not target the complement system that are in Phase 2 clinical trials, including therapies being developed by
Alcon, Gemini Therapeutics, Genentech, Lineage Cell Therapeutics, Regenerative Patch Technologies, and Stealth BioTherapeutics Inc., or Stealth, which
is evaluating elamipretide in a Phase 2b clinical trial in patients with GA.  Alexion has announced plans to initiate Phase 2 trials of danicopan in GA in the
second half of 2021.

PNH. The principal competitors for PNH, and possibly other indications in our hematology and nephrology programs are eculizumab (marketed as

Soliris) and ravulizumab (marketed as Ultomiris), C5 inhibitors developed and marketed by Alexion Pharmaceuticals, or Alexion.  Eculizumab and
ravulizumab are the only drugs currently approved for the treatment of PNH.  In December 2020, AstraZeneca announced that it has agreed to acquire
Alexion, with closing expected in the third quarter of 2021, pending regulatory approval.

21

We are aware of several other companies that are actively developing product candidates using complement inhibition for the treatment of PNH in

late-stage clinical development, including nomacopan, a small protein C5 complement inhibitor being developed by Akari Therapeutics, Plc. in Phase 3
clinical trials; BCX9930, a Factor D inhibitor being developed by BioCryst Pharmaceuticals, currently in Phase 1/2 clinical trials; zilucoplan, a cyclic
peptide C5 inhibitor developed by UCB S.A., currently in Phase 2 clinical trials, crovalimab, an anti-C5 antibody developed by Roche/Chugai, currently in
Phase 3 clinical trials; pozelimab, an anti-C5 antibody developed by Regeneron Pharmaceuticals, currently in Phase 2 clinical trials; and iptacopan
(formerly known as LNP-023), a Factor B inhibitor being developed by Novartis currently in Phase 3 clinical trials, as well as other products in early stages
of development, including cemdisiran, an RNAi therapeutic targeting C5 developed by Alnylam Pharmaceuticals, Inc. in early clinical trials.   Alexion is
developing danicopan, formerly ACHN-4471, an orally available complement factor D inhibitor, currently in Phase 3 clinical trials as a cotreatment or
combination product with eculizumab, and next generation complement factor D inhibitors ACHN-5528 and ACHN-5548 in early clinical development.

Amgen is developing ABP959, a biosimilar for eculizumab that is in Phase 3 development, and other non-US entities are developing biosimilars
for eculizumab in local markets. The approval of a biosimilar or a generic to one of our products or a product with which we compete could have a material
impact on our business because it may be significantly less costly to bring to market and may be priced significantly lower than our products or the other
products with which we compete.

CAD.  There are no currently marketed drug treatments for CAD but treatments in development, include sutimlimab, a C1s monoclonal antibody

inhibitor, being developed by Sanofi, has completed Phase 3 clinical trials; and parsaclisib, a PI3K-d inhibitor, being developed by Incyte Corporation, in
Phase 2 clinical trials.

C3G. There are no currently marketed drug treatments for C3 glomerulopathy, but treatments in development include narsoplimab (OMS721), a

human monoclonal antibody to mannose-binding lectin-associated serine protease-2 (MASP-2) that blocks the lectin pathway, being developed by Omeros
Corp., in Phase 2 clinical trials; avacopan, an oral C5aR-inhibitor developed by ChemoCentryx, Inc., in Phase 2 clinical trials; Iptacopan, being developed
by Novartis, for C3 glomerulopathy is in Phase 2 clinical trials; and danicopan, being developed by Alexion for C3G, in Phase 2 clinical trials.

ALS. Currently there are four drug treatments approved by the FDA for treatment of ALS or its symptoms, including edaravone marketed as
Radicava by Mitsubishi Tanabe Pharma America; riluzole, now generic; thickened riluzole, marketed as Tiglutik by ITF Pharma, and dextromethorphan
HBr/quinidine sulfate (marketed as Nuedexta by Avanir Pharmaceuticals.   Various companies are conducting clinical trials for symptoms of, or
neurological conditions, related to, ALS, with over 50 molecules currently in development that target a broad array of biology, including at least three other
anti-complement therapies: Ultomiris by Alexion, in Phase 3 trials, Zilucoplan by UCB/Ra in Phase 2 clinical trials, and ANX005 by Annexon
Biosciences.  Additionally, Amylyx Pharmaceuticals, Inc. recently reported positive results from their Phase 2 study of AMX0035.

HSCT-TMA. Currently there are three treatments in Phase 3 clinical trials:  Ultomiris, developed by Alexion, nomacopan being developed by Akari,

and narsoplimab, being developed by Omeros.

ARDS incident to COVID-19.  We are aware of various companies conducting clinical trials for treatments of respiratory conditions secondary to

COVID-19, including targeted and broad anti-inflammatory approaches being evaluated in phase 2 and phase 3 trials. We are aware of several anti-
complement product candidates currently being developed in respiratory conditions secondary to COVID-19, including two C3 inhibition approaches,
some of which are in phase 3 development.  

Sales and Marketing

Apellis retains U.S. commercialization rights for systemic pegcetacoplan and worldwide commercial rights for ophthalmological pegcetacoplan.

We plan to conduct commercial development for systemic pegcetacoplan within the United States.   We have developed focused capabilities to
commercialize development programs for certain indications where we believe that the medical specialists for the indications are sufficiently
concentrated to allow us to effectively promote the product with a targeted sales team. In particular, for PNH we have defined our marketing, disease
education, patient support and distribution strategies, identified primary and secondary payers representing a significant percentage of patients with PNH,
have built our field market access team, and are building our sales team in preparation for a commercial launch.  Sobi received global co-development
and exclusive ex-US commercialization rights for systemic pegcetacoplan and will be responsible for the commercial development for systemic
pegcetacoplan outside the United States.

For our ophthalmological pegcetacoplan program and for programs involving compounds other than pegcetacoplan, we plan to develop our own

capabilities to commercialize our products worldwide.   We may seek to enter into collaborations that we believe may contribute to our ability to advance
development and ultimately commercialize our product candidates. We may also seek to enter into collaborations where we believe that realizing the full
commercial value of our development programs will require access to broader geographic markets or the pursuit of broader patient populations or
indications.

22

Manufacturing

We do not currently own or operate manufacturing facilities for the production of clinical or commercial quantities of our product candidates.

Although we intend to rely on third-party contract manufacturers to produce our products, we have recruited personnel with experience to manage the
third-party contract manufacturers producing our product candidates and other product candidates or products that we may develop in the future.

The process for manufacturing our product candidates consists of chemical synthesis, purification using liquid chromatography, and freeze drying

into solid form. The drug substance is then dissolved in solution and aliquoted into small vials for individual dosing.  Each of these steps involves a
relatively routine chemical engineering process. We expect the costs associated with manufacturing drug product for our product candidates may be
comparable to the current manufacturing costs for other similarly sized peptide-based components.

We have engaged a limited number of third-party manufacturers to provide all of our raw materials, drug substances and finished products for use in

clinical trials.  In particular, we have entered into a commercial supply agreement with Bachem Americas, Inc., or Bachem, to purchase a significant
portion of our requirements for the pegcetacoplan drug substance over the next five years. Our raw materials, drug substances and finished products have
been produced under master service contracts and specific work orders from these manufacturers pursuant to agreements that include specific supply
timelines and volume and quality expectations. We choose the third-party manufacturers of the raw materials and drug substances based on the volume
required and the regulatory requirements at the relevant stage of development. All lots of drug substances and finished products used in clinical trials are
manufactured under current good manufacturing practices. Separate third-party manufacturers are for fill and finish services and for labeling and shipment
of the final drug products to the clinical trial sites.

We believe that our manufacturing capabilities are sufficient to supply pegcetacoplan at the scale and with the quality required for our ongoing and

planned clinical trials, our commercialization efforts and our collaboration with Sobi   We continuously review our supply chain risk, including with respect
to our manufacturing footprint, and update and implement risk mitigation plans.

Commercial Supply Agreement with Bachem

On December 30, 2020, we entered into a commercial supply agreement, or the Bachem Agreement, with Bachem to supply Company with the

drug substance for the finished dosage form of pegcetacoplan.

Under the Supply Agreement, we agreed to purchase from Bachem a significant portion of our requirements for the drug substance during the term

of the agreement, and to purchase all of our requirements for drug substance for commercial sale, subject to certain exceptions, for a period after the
effective date of the agreement.

Unless earlier terminated, the initial term of the Bachem Agreement continues for five years, or the Initial Term. Thereafter, the Bachem Agreement

will automatically renew for an additional two-year term. At least 24 months prior to the end of the Initial Term, Bachem will notify us in writing if it is
willing to continue to manufacture and supply the drug substance following the end of the Initial Term. For a period of 12 months after receipt of such
notice, we have the right to negotiate pricing terms that would apply during the renewal term, which upon agreement will be finalized in an amendment to
the Bachem Agreement. We may terminate the Bachem Agreement in the event any required license, permit or certificate of Bachem related to the
manufacturing facility or the drug substance is not approved or issued (or is withdrawn) by the relevant governmental authority. Additionally, each party
may terminate the Bachem Agreement upon an uncured material breach of the Bachem Agreement by the other party or upon the other party’s insolvency
or bankruptcy.

The Bachem Agreement also includes customary provisions relating to, among others, delivery, inspection procedures, warranties, quality, storage,

handling and transport, intellectual property, confidentiality and indemnification.

Government Regulation and Product Approvals

Government authorities in the United States, at the federal, state and local level, and in other countries and jurisdictions, including the European

Union, extensively regulate, among other things, the research, development, testing, manufacture, quality control, approval, packaging, storage,
recordkeeping, labeling, advertising, promotion, distribution, marketing, pricing, reimbursement, post-approval monitoring and reporting, and import and
export of pharmaceutical products. The processes for obtaining regulatory approvals in the United States and in foreign countries and jurisdictions, along
with subsequent compliance with applicable statutes and regulations and other regulatory authorities, require the expenditure of substantial time and
financial resources.

23

Review and Approval of Drugs in the United States

In the United States, the FDA regulates drugs under the Federal Food, Drug, and Cosmetic Act, or FDCA, and implementing regulations. The
failure to comply with applicable U.S. requirements at any time during the product development process, approval process or after approval may subject an
applicant and/or sponsor to a variety of administrative or judicial sanctions, including refusal by the FDA to approve pending applications, withdrawal of
an approval, imposition of a clinical hold, issuance of warning letters and other types of letters, product recalls, product seizures, total or partial suspension
of production or distribution, injunctions, fines, refusals of government contracts, restitution, disgorgement of profits, or civil or criminal investigations and
penalties brought by the FDA and the Department of Justice or other governmental entities, including state agencies.

An applicant seeking approval to market and distribute a new drug product in the United States must typically undertake the following:

•

•

•

•

•

•

•

•

•

•

completion of preclinical laboratory tests, animal studies and formulation studies in compliance with the FDA’s good laboratory practice, or
GLP, regulations;

submission to the FDA of an IND, which must take effect before human clinical trials may begin;

approval by an independent institutional review board representing each clinical site before each clinical trial may be initiated;

performance of adequate and well-controlled human clinical trials in accordance with good clinical practices, or GCP, to establish the safety
and efficacy of the proposed drug product for each indication;

preparation and submission to the FDA of a NDA;

review of the product by an FDA advisory committee, where appropriate or if applicable;

satisfactory completion of one or more FDA inspections of the manufacturing facility or facilities at which the product, or components
thereof, are produced to assess compliance with current Good Manufacturing Practices, or cGMP, requirements and to assure that the
facilities, methods and controls are adequate to preserve the product’s identity, strength, quality and purity;

satisfactory completion of FDA audits of clinical trial sites to assure compliance with GCPs and the integrity of the clinical data;

payment of user fees and securing FDA approval of the NDA; and

compliance with any post-approval requirements, including Risk Evaluation and Mitigation Strategies, or REMS, and post-approval studies
required by the FDA.

Preclinical Studies

Before an applicant begins testing a product candidate with potential therapeutic value in humans, the product candidate enters the preclinical testing

stage. Preclinical studies include laboratory evaluation of the purity and stability of the manufactured drug substance or active pharmaceutical ingredient
and the formulated drug or drug product, as well as in vitro and animal studies to assess the safety and activity of the drug for initial testing in humans and
to establish a rationale for therapeutic use. The conduct of preclinical studies is subject to federal regulations and requirements, including GLP regulations.

Companies usually must complete some long-term preclinical testing, such as animal tests of reproductive adverse events and carcinogenicity, and

must also develop additional information about the chemistry and physical characteristics of the investigational product and finalize a process for
manufacturing the product in commercial quantities in accordance with cGMP requirements. The manufacturing process must be capable of consistently
producing quality batches of the product candidate and, among other things, the manufacturer must develop methods for testing the identity, strength,
quality and purity of the final product. Additionally, appropriate packaging must be selected and tested and stability studies must be conducted to
demonstrate that the product candidate does not undergo unacceptable deterioration over its shelf life.

The IND and IRB Processes

An IND is an exemption from the FDCA that allows an unapproved drug to be shipped in interstate commerce for use in an investigational clinical
trial and a request for FDA authorization to administer an investigational drug to humans. Such authorization must be secured prior to interstate shipment
and administration of any new drug that is not the subject of an approved NDA. In support of a request for an IND, applicants must submit a protocol for
each clinical trial and any subsequent protocol amendments must be submitted to the FDA as part of the IND. In addition, the results of the preclinical tests,
together with manufacturing information, analytical data, any available clinical data or literature and plans for clinical trials, among other things, are
submitted to the FDA as part of an IND. The FDA requires a 30-day waiting period after the filing of each IND before clinical trials may begin. This
waiting

24

 
 
 
 
 
 
 
 
 
 
period is designed to allow the FDA to review the IND to determine whether human research subjects will be exposed to unreasonable health risks. At any
time during this 30-day period, the FDA may raise concerns or questions about the conduct of the trials as outlined in the IND and impose a clinical hold or
partial clinical hold. In this case, the IND sponsor and the FDA must resolve any outstanding concerns before clinical trials can begin.

Following commencement of a clinical trial under an IND, the FDA may also place a clinical hold or partial clinical hold on that trial. A clinical

hold is an order issued by the FDA to the sponsor to delay a proposed clinical investigation or to suspend an ongoing investigation. A partial clinical hold is
a delay or suspension of only part of the clinical work requested under the IND. For example, a specific protocol or part of a protocol is not allowed to
proceed, while other protocols may do so. No more than 30 days after imposition of a clinical hold or partial clinical hold, the FDA will provide the
sponsor a written explanation of the basis for the hold. Following issuance of a clinical hold or partial clinical hold, an investigation may only resume after
the FDA has notified the sponsor that the investigation may proceed. The FDA will base that determination on information provided by the sponsor
correcting the deficiencies previously cited or otherwise satisfying the FDA that the investigation can proceed.

A sponsor may choose, but is not required, to conduct a foreign clinical study under an IND. When a foreign clinical study is conducted under an

IND, all FDA IND requirements must be met unless waived. When the foreign clinical study is not conducted under an IND, the sponsor must ensure that
the study complies with certain FDA requirements in order to use the study as support for an IND or application for marketing approval. Those
requirements provide that such studies must be conducted in accordance with GCP, including review and approval by an independent ethics committee, or
IEC, and informed consent from subjects.

In addition to the IND requirements, an IRB representing each institution participating in the clinical trial must review and approve the plan for any
clinical trial before it commences at that institution, and the IRB must conduct continuing review and reapprove the study at least annually. The IRB must
review and approve, among other things, the study protocol and informed consent information to be provided to study subjects. An IRB must operate in
compliance with FDA regulations. An IRB can suspend or terminate approval of a clinical trial at its institution, or an institution it represents, if the clinical
trial is not being conducted in accordance with the IRB’s requirements or if the product candidate has been associated with unexpected serious harm to
patients.

Additionally, some trials are overseen by an independent group of qualified experts organized by the trial sponsor, known as a data safety
monitoring board, or DSMB, or committee. This group provides authorization for whether or not a trial may move forward at designated check points
based on access that only the group maintains to available data from the study. Suspension or termination of development during any phase of clinical trials
can occur if it is determined that the participants or patients are being exposed to an unacceptable health risk. Other reasons for suspension or termination
may be made by us based on evolving business objectives and/or competitive climate.

Information about certain clinical trials must be submitted within specific timeframes to the National Institutes of Health, or NIH, for public

dissemination on its ClinicalTrials.gov website.

Expanded Access to an Investigational Drug for Treatment Use

Expanded access, sometimes called “compassionate use,” is the use of investigational new drug products outside of clinical trials to treat patients
with serious or immediately life-threatening diseases or conditions when there are no comparable or satisfactory alternative treatment options. The rules
and regulations related to expanded access are intended to improve access to investigational drugs for patients who may benefit from investigational
therapies. FDA regulations allow access to investigational drugs under an IND by the company or the treating physician for treatment purposes on a case-
by-case basis for: individual patients (single-patient IND applications for treatment in emergency settings and non-emergency settings); intermediate-size
patient populations; and larger populations for use of the drug under a treatment protocol or Treatment IND Application.

When considering an IND application for expanded access to an investigational product with the purpose of treating a patient or a group of patients,

the sponsor and treating physicians or investigators will determine suitability when all of the following criteria apply: patient(s) have a serious or
immediately life-threatening disease or condition, and there is no comparable or satisfactory alternative therapy to diagnose, monitor, or treat the disease or
condition; the potential patient benefit justifies the potential risks of the treatment and the potential risks are not unreasonable in the context or condition to
be treated; and the expanded use of the investigational drug for the requested treatment will not interfere initiation, conduct, or completion of clinical
investigations that could support marketing approval of the product or otherwise compromise the potential development of the product.

There is no obligation for a sponsor to make its drug products available for expanded access; however, as required by the 21st Century Cures Act

(the “Cures Act”), passed in 2016, if a sponsor has a policy regarding how it responds to expanded access requests, it must make that policy publicly
available. This requirement applies upon the earlier of initiation of a Phase 2 or Phase 3 study; or 15 days after the investigational drug or biologic receives
designation as a breakthrough therapy, fast track product, or regenerative medicine advanced therapy. 

In addition, on May 30, 2018, the Right to Try Act, was signed into law. The law, among other things, provides a federal framework for certain
patients to access certain investigational new drug products that have completed a Phase I clinical trial and that are undergoing investigation for FDA
approval. Under certain circumstances, eligible patients can seek treatment without enrolling in

25

clinical trials and without obtaining FDA permission under the FDA expanded access program. There is no obligation for a drug manufacturer to make its
drug products available to eligible patients as a result of the Right to Try Act, but the manufacturer must develop an internal policy and respond to patient
requests according to that policy

Human Clinical Studies in Support of an NDA

Clinical trials involve the administration of the investigational product to human subjects under the supervision of qualified investigators in
accordance with GCP requirements, which include, among other things, the requirement that all research subjects provide their informed consent in writing
before their participation in any clinical trial. Clinical trials are conducted under written study protocols detailing, among other things, the inclusion and
exclusion criteria, the objectives of the study, the parameters to be used in monitoring safety and the effectiveness criteria to be evaluated.

Human clinical trials are typically conducted in the following sequential phases, which may overlap or be combined:

•

•

•

•

Phase 1: The drug is initially introduced into healthy human subjects or, in certain indications such as cancer, patients with the target disease
or condition and tested for safety, dosage tolerance, absorption, metabolism, distribution, excretion and, if possible, to gain an early indication
of its effectiveness and to determine optimal dosage.

Phase 2: The drug is administered to a limited patient population to identify possible adverse effects and safety risks, to preliminarily evaluate
the efficacy of the product for specific targeted diseases and to determine dosage tolerance and optimal dosage.

Phase 3: The drug is administered to an expanded patient population, generally at geographically dispersed clinical trial sites, in well-
controlled clinical trials to generate enough data to statistically evaluate the efficacy and safety of the product for approval, to establish the
overall risk-benefit profile of the product, and to provide adequate information for the labeling of the product.

Phase 4: Post-approval studies, which are conducted following initial approval, are typically conducted to gain additional experience and data
from treatment of patients in the intended therapeutic indication.

Progress reports detailing the results of the clinical trials must be submitted at least annually to the FDA and more frequently if serious adverse

events occur. In addition, IND safety reports must be submitted to the FDA for any of the following: serious and unexpected suspected adverse reactions;
findings from other studies or animal or in vitro testing that suggest a significant risk in humans exposed to the drug; and any clinically important increase
in the case of a serious suspected adverse reaction over that listed in the protocol or investigator brochure. Phase 1, Phase 2 and Phase 3 clinical trials may
not be completed successfully within any specified period, or at all. The FDA will typically inspect one or more clinical sites to assure compliance with
GCP and the integrity of the clinical data submitted.

Concurrent with clinical trials, companies often complete additional animal studies and must also develop additional information about the
chemistry and physical characteristics of the drug as well as finalize a process for manufacturing the product in commercial quantities in accordance with
cGMP requirements. The manufacturing process must be capable of consistently producing quality batches of the drug candidate and, among other things,
must develop methods for testing the identity, strength, quality, purity, and potency of the final drug. Additionally, appropriate packaging must be selected
and tested and stability studies must be conducted to demonstrate that the drug candidate does not undergo unacceptable deterioration over its shelf life.

Pediatric Studies

Under the Pediatric Research Equity Act of 2003, an NDA or supplement thereto must contain data that are adequate to assess the safety and

effectiveness of the drug product for the claimed indications in all relevant pediatric subpopulations, and to support dosing and administration for each
pediatric subpopulation for which the product is safe and effective. With enactment of the Food and Drug Safety and Innovation Act, or the FDASIA, in
2012, sponsors must also submit pediatric study plans prior to the assessment data. Those plans must contain an outline of the proposed pediatric study or
studies the applicant plans to conduct, including study objectives and design, any deferral or waiver requests, and other information required by regulation.
The applicant, the FDA, and the FDA’s internal review committee must then review the information submitted, consult with each other, and agree upon a
final plan. The FDA or the applicant may request an amendment to the plan at any time. For drugs intended to treat a serious or life-threatening disease or
condition, the FDA must, upon the request of an applicant, meet to discuss preparation of the initial pediatric study plan or to discuss deferral or waiver of
pediatric assessments.

The FDA may, on its own initiative or at the request of the applicant, grant deferrals for submission of some or all pediatric data until after approval
of the product for use in adults, or full or partial waivers from the pediatric data requirements. Additional requirements and procedures relating to deferral
requests and requests for extension of deferrals are contained in the Food and Drug Administration Safety and Innovation Act, or FDASIA.  The FDA
maintains a list of diseases that are exempt from PREA requirements due to low prevalence of disease in the pediatric population. Congress amended the
FDA Reauthorization Act of 2017, or FDARA. Previously, drugs that had been granted orphan drug designation were exempt from the requirements of the
Pediatric Research Equity Act. Under the amended section 505B, beginning on August 18, 2020, the submission of a pediatric assessment,

26

 
 
 
 
waiver or deferral will be required for certain molecularly targeted cancer indications with the submission of an application or supplement to an
application.

Submission of an NDA to the FDA

Assuming successful completion of required clinical testing and other requirements, the results of the preclinical studies and clinical trials, together

with detailed information relating to the product’s chemistry, manufacture, controls and proposed labeling, among other things, are submitted to the FDA as
part of an NDA requesting approval to market the drug product for one or more indications. Under federal law, the submission of most NDAs is subject to
an application user fee, which for federal fiscal year 2021 is $2,875,842 for an application requiring clinical data. The sponsor of an approved NDA is also
subject to an annual program fee, which for federal fiscal year 2021 is $336,432. Certain exceptions and waivers are available for some of these fees, such
as an exception from the application fee for products with orphan designation and a waiver for certain small businesses.

The FDA conducts a preliminary review of an NDA within 60 days of its receipt and strives to inform the sponsor by the 74th day after the FDA’s

receipt of the submission to determine whether the application is sufficiently complete to permit substantive review. The FDA may request additional
information rather than accept an NDA for filing. In this event, the application must be resubmitted with the additional information. The resubmitted
application is also subject to review before the FDA accepts it for filing. Once the submission is accepted for filing, the FDA begins an in-depth substantive
review. The FDA has agreed to certain performance goals in the review process of NDAs. Most such applications are meant to be reviewed within ten
months from the date of filing, and most applications for “priority review” products are meant to be reviewed within six months of filing. The review
process may be extended by the FDA for three additional months to consider new information or clarification provided by the applicant to address an
outstanding deficiency identified by the FDA following the original submission.

Before approving an NDA, the FDA typically will inspect the facility or facilities where the product is or will be manufactured. These pre-approval

inspections may cover all facilities associated with an NDA submission, including drug component manufacturing (such as active pharmaceutical
ingredients), finished drug product manufacturing, and control testing laboratories. The FDA will not approve an application unless it determines that the
manufacturing processes and facilities comply with cGMP requirements and adequate to assure consistent production of the product within required
specifications. Additionally, before approving an NDA, the FDA will typically inspect one or more clinical sites to assure compliance with GCP. Under the
FDA Reauthorization Act of 2017, or FDARA, the FDA must implement a protocol to expedite review of responses to inspection reports pertaining to
certain drug applications, including applications for drugs in a shortage or drugs for which approval is dependent on remediation of conditions identified in
the inspection report.

In addition, as a condition of approval, the FDA may require an applicant to develop a REMS. REMS use risk minimization strategies beyond the

professional labeling to ensure that the benefits of the product outweigh the potential risks. To determine whether a REMS is needed, the FDA will consider
the size of the population likely to use the product, seriousness of the disease, expected benefit of the product, expected duration of treatment, seriousness
of known or potential adverse events, and whether the product is a new molecular entity. REMS can include medication guides, physician communication
plans for healthcare professionals, and elements to assure safe use, or ETASU. ETASU may include, but are not limited to, special training or certification
for prescribing or dispensing, dispensing only under certain circumstances, special monitoring, and the use of patient registries. The FDA may require a
REMS before approval or post-approval if it becomes aware of a serious risk associated with use of the product. The requirement for a REMS can
materially affect the potential market and profitability of a product.

The FDA may refer an application for a novel drug to an advisory committee or explain why such referral was not made. Typically, an advisory

committee is a panel of independent experts, including clinicians and other scientific experts, that reviews, evaluates and provides a recommendation as to
whether the application should be approved and under what conditions. The FDA is not bound by the recommendations of an advisory committee, but it
considers such recommendations carefully when making decisions.

Fast Track, Breakthrough Therapy, Priority Review and Regenerative Advanced Therapy Designations

The FDA is authorized to designate certain products for expedited review if they are intended to address an unmet medical need in the treatment of a

serious or life-threatening disease or condition. These programs are referred to as fast track designation, breakthrough therapy designation, priority review
and regenerative advanced therapy designation.

Specifically, the FDA may designate a product for fast track review if it is intended, whether alone or in combination with one or more other
products, for the treatment of a serious or life-threatening disease or condition, and it demonstrates the potential to address unmet medical needs for such a
disease or condition. For fast track products, sponsors may have greater interactions with the FDA and the FDA may initiate review of sections of a fast
track product’s application before the application is complete. This rolling review may be available if the FDA determines, after preliminary evaluation of
clinical data submitted by the sponsor, that a fast track product may be effective. The sponsor must also provide, and the FDA must approve, a schedule for
the submission of the remaining information and the sponsor must pay applicable user fees. However, the FDA’s time period goal for reviewing a fast track
application does not begin until the last section of the application is submitted. In addition, the fast track designation may be withdrawn by the FDA if the
FDA believes that the designation is no longer supported by data emerging in the clinical trial process.

27

Second, a product may be designated as a breakthrough therapy if it is intended, either alone or in combination with one or more other products, to

treat a serious or life-threatening disease or condition and preliminary clinical evidence indicates that the product may demonstrate substantial
improvement over existing therapies on one or more clinically significant endpoints, such as substantial treatment effects observed early in clinical
development. The FDA may take certain actions with respect to breakthrough therapies, including holding meetings with the sponsor throughout the
development process; providing timely advice to the product sponsor regarding development and approval; involving more senior staff in the review
process; assigning a cross-disciplinary project lead for the review team; and taking other steps to design the clinical trials in an efficient manner.

Third, the FDA may designate a product for priority review if it is a product that treats a serious condition and, if approved, would provide a

significant improvement in safety or effectiveness. The FDA determines, on a case-by-case basis, whether the proposed product represents a significant
improvement when compared with other available therapies. Significant improvement may be illustrated by evidence of increased effectiveness in the
treatment of a condition, elimination or substantial reduction of a treatment-limiting product reaction, documented enhancement of patient compliance that
may lead to improvement in serious outcomes, and evidence of safety and effectiveness in a new subpopulation. A priority designation is intended to direct
overall attention and resources to the evaluation of such applications, and to shorten the FDA’s goal for taking action on a marketing application from ten
months to six months.

Fourth, with passage of the 21st Century Cures Act, or the Cures Act, in December 2016, Congress authorized the FDA to accelerate review and

approval of products designated as regenerative advanced therapies. A product is eligible for this designation if it is a regenerative medicine therapy that is
intended to treat, modify, reverse or cure a serious or life-threatening disease or condition and preliminary clinical evidence indicates that the product has
the potential to address unmet medical needs for such disease or condition. The benefits of a regenerative advanced therapy designation include early
interactions with FDA to expedite development and review, benefits available to breakthrough therapies, potential eligibility for priority review and
accelerated approval based on surrogate or intermediate endpoints.

Accelerated Approval Pathway

The FDA may grant accelerated approval to a drug for a serious or life-threatening condition that provides meaningful therapeutic advantage to

patients over existing treatments based upon a determination that the drug has an effect on a surrogate endpoint that is reasonably likely to predict clinical
benefit. The FDA may also grant accelerated approval for such a condition when the product has an effect on an intermediate clinical endpoint that can be
measured earlier than an effect on irreversible morbidity or mortality, or IMM, and that is reasonably likely to predict an effect on IMM or other clinical
benefit, taking into account the severity, rarity or prevalence of the condition and the availability or lack of alternative treatments. Drugs granted
accelerated approval must meet the same statutory standards for safety and effectiveness as those granted traditional approval.

For the purposes of accelerated approval, a surrogate endpoint is a marker, such as a laboratory measurement, radiographic image, physical sign or

other measure that is thought to predict clinical benefit but is not itself a measure of clinical benefit. Surrogate endpoints can often be measured more easily
or more rapidly than clinical endpoints. An intermediate clinical endpoint is a measurement of a therapeutic effect that is considered reasonably likely to
predict the clinical benefit of a drug, such as an effect on IMM. There is limited experience with accelerated approvals by the FDA based on intermediate
clinical endpoints. However, the FDA has indicated that such endpoints generally may support accelerated approval where the therapeutic effect measured
by the endpoint is not itself a clinical benefit and basis for traditional approval, if there is a basis for concluding that the therapeutic effect is reasonably
likely to predict the ultimate clinical benefit of a drug.

The accelerated approval pathway is most often used in settings in which the course of a disease is long and an extended period of time is required

to measure the intended clinical benefit of a drug, even if the effect on the surrogate or intermediate clinical endpoint occurs rapidly. Thus, accelerated
approval has been used extensively in the development and approval of drugs for treatment of a variety of cancers in which the goal of therapy is generally
to improve survival or decrease morbidity and the duration of the typical disease course requires lengthy and sometimes large trials to demonstrate a
clinical or survival benefit.

The accelerated approval pathway is usually contingent on a sponsor’s agreement to conduct, in a diligent manner, additional post-approval

confirmatory studies to verify and describe the drug’s clinical benefit. As a result, a drug candidate approved on this basis is subject to rigorous post-
marketing compliance requirements, including the completion of Phase 4 or post-approval clinical trials to confirm the effect on the clinical endpoint.
Failure to conduct required post-approval studies, or confirm a clinical benefit during post-marketing studies, would allow the FDA to withdraw the drug
from the market on an expedited basis. All promotional materials for drug candidates approved under accelerated regulations are subject to prior review by
the FDA.

The FDA’s Decision on an NDA

On the basis of the FDA’s evaluation of the NDA and accompanying information, including the results of the inspection of the manufacturing

facilities, the FDA may issue an approval letter or a complete response letter, or CRL. An approval letter authorizes

28

commercial marketing of the product with specific prescribing information for specific indications. A CRL generally outlines the deficiencies in the
submission and may require substantial additional testing or information in order for the FDA to reconsider the application. If and when those deficiencies
have been addressed to the FDA’s satisfaction in a resubmission of the NDA, the FDA will issue an approval letter. The FDA has committed to reviewing
such resubmissions in two or six months depending on the type of information included. Even with submission of this additional information, the FDA
ultimately may decide that the application does not satisfy the regulatory criteria for approval.

If the FDA approves a product, it may limit the approved indications for use for the product, require that contraindications, warnings or precautions
be included in the product labeling, require that post-approval studies, including Phase 4 clinical trials, be conducted to further assess the drug’s safety after
approval, require testing and surveillance programs to monitor the product after commercialization, or impose other conditions, including distribution
restrictions or other risk management mechanisms, including REMS, which can materially affect the potential market and profitability of the product. The
FDA may prevent or limit further marketing of a product based on the results of post-market studies or surveillance programs. After approval, many types
of changes to the approved product, such as adding new indications, manufacturing changes and additional labeling claims, are subject to further testing
requirements and FDA review and approval.

Post-Approval Requirements

Drugs manufactured or distributed pursuant to FDA approvals are subject to pervasive and continuing regulation by the FDA, including, among
other things, requirements relating to recordkeeping, periodic reporting, product sampling and distribution, advertising and promotion and reporting of
adverse experiences with the product. After approval, most changes to the approved product, such as adding new indications or other labeling claims, are
subject to prior FDA review and approval. There also are continuing, annual user fee requirements for any marketed products and the establishments at
which such products are manufactured, as well as new application fees for supplemental applications with clinical data.

In addition, drug manufacturers and other entities involved in the manufacture and distribution of approved drugs are required to register their

establishments with the FDA and state agencies and are subject to periodic unannounced inspections by the FDA and these state agencies for compliance
with cGMP requirements. Changes to the manufacturing process are strictly regulated and often require prior FDA approval before being implemented.
FDA regulations also require investigation and correction of any deviations from cGMP and impose reporting and documentation requirements upon the
sponsor and any third-party manufacturers that the sponsor may decide to use. Accordingly, manufacturers must continue to expend time, money, and effort
in the area of production and quality control to maintain cGMP compliance.

Once an approval is granted, the FDA may withdraw the approval if compliance with regulatory requirements and standards is not maintained or if

problems occur after the product reaches the market. Later discovery of previously unknown problems with a product, including adverse events of
unanticipated severity or frequency, or with manufacturing processes, or failure to comply with regulatory requirements, may result in revisions to the
approved labeling to add new safety information; imposition of post-market studies or clinical trials to assess new safety risks; or imposition of distribution
or other restrictions under a REMS program. Other potential consequences include, among other things:

•

•

•

•

•

restrictions on the marketing or manufacturing of the product, complete withdrawal of the product from the market or product recalls;

fines, warning letters or holds on post-approval clinical trials;

refusal of the FDA to approve pending NDAs or supplements to approved NDAs, or suspension or revocation of product license approvals;

product seizure or detention, or refusal to permit the import or export of products; or

injunctions or the imposition of civil or criminal penalties.

The FDA strictly regulates the marketing, labeling, advertising and promotion of prescription drug products placed on the market. This regulation

includes, among other things, standards and regulations for direct-to-consumer advertising, communications regarding unapproved uses, industry-
sponsored scientific and educational activities, and promotional activities involving the Internet and social media. Promotional claims about a drug’s safety
or effectiveness are prohibited before the drug is approved. After approval, a drug product generally may not be promoted for uses that are not approved by
the FDA, as reflected in the product’s prescribing information. In the United States, healthcare professionals are generally permitted to prescribe drugs for
such uses not described in the drug’s labeling, known as off-label uses, because the FDA does not regulate the practice of medicine. However, the FDA’s
regulations impose rigorous restrictions on manufacturers’ communications, prohibiting the promotion of off-label uses. It may be permissible, under very
specific, narrow conditions, for a manufacturer to engage in nonpromotional, non-misleading communication regarding off-label information, such as
distributing scientific or medical journal information. If a company is found to have promoted off-label uses, it may become subject to adverse public
relations and administrative and judicial enforcement by the FDA, the Department of Justice, or the Office of the Inspector General of the Department of
Health and Human Services, as well as state authorities. This

29

 
 
 
 
 
could subject a company to a range of penalties that could have a significant commercial impact, including civil and criminal fines and agreements that
materially restrict the manner in which a company promotes or distributes drug products. The federal government has levied large civil and criminal fines
against companies for alleged improper promotion and has also requested that companies enter into consent decrees or permanent injunctions under which
specified promotional conduct is changed or curtailed.

In addition, the distribution of prescription pharmaceutical products is subject to the Prescription Drug Marketing Act, or PDMA, and its
implementation regulations, as well as the Drug Supply Chain Security Act, or DSCSA, which regulates the distribution of and tracing of prescription
drugs and prescription drug samples at the federal level and sets minimum standards for the regulation of drug distributors by the states. The PDMA, its
implementing regulations and state laws limit the distribution of prescription pharmaceutical product samples, and the DSCSA imposes requirements to
ensure accountability in distribution and to identify and remove counterfeit and other illegitimate products from the market.

Abbreviated New Drug Applications for Generic Drugs

In 1984, with passage of the Hatch-Waxman Amendments to the FDCA, Congress authorized the FDA to approve generic drugs that are the same as

drugs previously approved by the FDA under the NDA provisions of the statute. To obtain approval of a generic drug, an applicant must submit an
abbreviated new drug application, or ANDA, to the agency. In support of such applications, a generic manufacturer may rely on the preclinical and clinical
testing previously conducted for a drug product previously approved under an NDA, known as the reference-listed drug, or RLD.

Specifically, in order for an ANDA to be approved, the FDA must find that the generic version is identical to the RLD with respect to the active

ingredients, the route of administration, the dosage form, and the strength of the drug. At the same time, the FDA must also determine that the generic drug
is “bioequivalent” to the innovator drug. Under the statute, a generic drug is bioequivalent to a RLD if “the rate and extent of absorption of the drug do not
show a significant difference from the rate and extent of absorption of the listed drug...”

Upon approval of an ANDA, the FDA indicates whether the generic product is “therapeutically equivalent” to the RLD in its publication “Approved

Drug Products with Therapeutic Equivalence Evaluations,” also referred to as the “Orange Book.” Physicians and pharmacists consider a therapeutic
equivalent generic drug to be fully substitutable for the RLD. In addition, by operation of certain state laws and numerous health insurance programs, the
FDA’s designation of therapeutic equivalence often results in substitution of the generic drug without the knowledge or consent of either the prescribing
physician or patient.

Under the Hatch-Waxman Amendments, the FDA may not approve an ANDA until any applicable period of non-patent exclusivity for the RLD has
expired. The FDCA provides a period of five years of non-patent data exclusivity for a new drug containing a new chemical entity. For the purposes of this
provision, a new chemical entity, or NCE, is a drug that contains no active moiety that has previously been approved by the FDA in any other NDA. An
active moiety is the molecule or ion responsible for the physiological or pharmacological action of the drug substance. In cases where such NCE
exclusivity has been granted, an ANDA may not be filed with the FDA until the expiration of five years unless the submission is accompanied by a
Paragraph IV certification, in which case the applicant may submit its application four years following the original product approval.

The FDCA also provides for a period of three years of exclusivity if the NDA includes reports of one or more new clinical investigations, other than

bioavailability or bioequivalence studies, that were conducted by or for the applicant and are essential to the approval of the application. This three-year
exclusivity period often protects changes to a previously approved drug product, such as a new dosage form, route of administration, combination or
indication. Three-year exclusivity would be available for a drug product that contains a previously approved active moiety, provided the statutory
requirement for a new clinical investigation is satisfied. Unlike five-year NCE exclusivity, an award of three-year exclusivity does not block the FDA from
accepting ANDAs seeking approval for generic versions of the drug as of the date of approval of the original drug product. The FDA typically makes
decisions about awards of data exclusivity shortly before a product is approved.

Hatch-Waxman Patent Certification and the 30-Month Stay

Upon approval of an NDA or a supplement thereto, NDA sponsors are required to list with the FDA each patent with claims that cover the
applicant’s product or an approved method of using the product. Each of the patents listed by the NDA sponsor is published in the Orange Book. When an
ANDA applicant files its application with the FDA, the applicant is required to certify to the FDA concerning any patents listed for the reference product in
the Orange Book, except for patents covering methods of use for which the ANDA applicant is not seeking approval. To the extent that the Section 505(b)
(2) applicant is relying on studies conducted for an already approved product, the applicant is required to certify to the FDA concerning any patents listed
for the approved product in the Orange Book to the same extent that an ANDA applicant would.

Specifically, the applicant must certify with respect to each patent that:

•

the required patent information has not been filed;

30

 
•

•

•

the listed patent has expired;

the listed patent has not expired, but will expire on a particular date and approval is sought after patent expiration; or

the listed patent is invalid, unenforceable or will not be infringed by the new product.

A certification that the new product will not infringe the already approved product’s listed patents or that such patents are invalid or unenforceable is

called a Paragraph IV certification. If the applicant does not challenge the listed patents or indicates that it is not seeking approval of a patented method of
use, the ANDA application will not be approved until all the listed patents claiming the referenced product have expired (other than method of use patents
involving indications for which the ANDA applicant is not seeking approval).

If the ANDA applicant has provided a Paragraph IV certification to the FDA, the applicant must also send notice of the Paragraph IV certification to
the NDA and patent holders once the ANDA has been accepted for filing by the FDA. The NDA and patent holders may then initiate a patent infringement
lawsuit in response to the notice of the Paragraph IV certification. The filing of a patent infringement lawsuit within 45 days after the receipt of a
Paragraph IV certification automatically prevents the FDA from approving the ANDA until the earlier of 30 months after the receipt of the Paragraph IV
notice, expiration of the patent, or a decision in the infringement case that is favorable to the ANDA applicant.

Pediatric Exclusivity

Pediatric exclusivity is another type of non-patent marketing exclusivity in the United States and, if granted, provides for the attachment of an
additional six months of marketing protection to the term of any existing regulatory exclusivity, including the non-patent and orphan exclusivity. This six-
month exclusivity may be granted if an NDA sponsor submits pediatric data that fairly respond to a written request from the FDA for such data. The data
do not need to show the product to be effective in the pediatric population studied; rather, if the clinical trial is deemed to fairly respond to the FDA’s
request, the additional protection is granted. If reports of requested pediatric studies are submitted to and accepted by the FDA within the statutory time
limits, whatever statutory or regulatory periods of exclusivity or patent protection cover the product are extended by six months. This is not a patent term
extension, but it effectively extends the regulatory period during which the FDA cannot approve another application. With regard to patents, the six-month
pediatric exclusivity period will not attach to any patents for which a generic (ANDA or 505(b)(2) NDA) applicant submitted a paragraph IV patent
certification, unless the NDA sponsor or patent owner first obtains a court determination that the patent is valid and infringed by a proposed generic
product.

Orphan Drug Designation and Exclusivity

Under the Orphan Drug Act, the FDA may designate a drug product as an “orphan drug” if it is intended to treat a rare disease or condition
(generally meaning that it affects fewer than 200,000 individuals in the United States, or more in cases in which there is no reasonable expectation that the
cost of developing and making a drug product available in the United States for treatment of the disease or condition will be recovered from sales of the
product). A company must request orphan product designation before submitting an NDA. If the request is granted, the FDA will disclose the identity of
the therapeutic agent and its potential use. Orphan product designation does not convey any advantage in or shorten the duration of the regulatory review
and approval process.

If a product with orphan status receives the first FDA approval for the disease or condition for which it has such designation or for a select

indication or use within the rare disease or condition for which it was designated, the product generally will be receiving orphan product exclusivity.
Orphan product exclusivity means that the FDA may not approve any other applications for the same product for the same indication for seven years,
except in certain limited circumstances. Those circumstances include instances in which another sponsor’s application for the same drug product and
indication is shown to be “clinically superior” to the previously approved drug. In this context, clinically superior means that the drug provides a significant
therapeutic advantage over and above the already approved drug in terms of greater efficacy, greater safety or by providing a major contribution to patient
care. Competitors may receive approval of different products for the indication for which the orphan product has exclusivity and may obtain approval for
the same product but for a different indication. If a drug or drug product designated as an orphan product ultimately receives marketing approval for an
indication broader than what was designated in its orphan product application, it may not be entitled to exclusivity.

Under FDARA, orphan exclusivity will not bar approval of another orphan drug under certain circumstances, including if a subsequent product with

the same drug for the same indication is shown to be clinically superior to the approved product on the basis of greater efficacy or safety, or providing a
major contribution to patient care, or if the company with orphan drug exclusivity is not able to meet market demand. The new legislation reverses prior
precedent holding that the Orphan Drug Act unambiguously required the FDA to recognize orphan exclusivity regardless of a showing of clinical
superiority.

Patent Term Restoration and Extension

A patent claiming a new drug product may be eligible for a limited patent term extension under the Hatch-Waxman Act, which permits a patent

restoration of up to five years for patent term lost during product development and the FDA regulatory review. The

31

 
 
 
 
restoration period granted is typically one-half the time between the effective date of an IND and the submission date of an NDA, plus the time between the
submission date of an NDA and the ultimate approval date. Patent term restoration cannot be used to extend the remaining term of a patent past a total of
14 years from the product’s approval date. Only one patent applicable to an approved drug product is eligible for the extension, and the application for the
extension must be submitted prior to the expiration of the patent in question. A patent that covers multiple drugs for which approval is sought can only be
extended in connection with one of the approvals. The U.S. Patent and Trademark Office reviews and approves the application for any patent term
extension or restoration in consultation with the FDA.

Review and Clearance or Approval of Medical Devices in the United States

Medical devices in the United States are strictly regulated by the FDA. Under the FDCA, a medical device is defined as an instrument, apparatus,
implement, machine, contrivance, implant, in vitro reagent, or other similar or related article, including a component part, or accessory which is, among
other things: intended for use in the diagnosis of disease or other conditions, or in the cure, mitigation, treatment, or prevention of disease, in man or other
animals; or intended to affect the structure or any function of the body of man or other animals, and which does not achieve its primary intended purposes
through chemical action within or on the body of man or other animals and which is not dependent upon being metabolized for the achievement of any of
its primary intended purposes. This definition provides a clear distinction between a medical device and other FDA regulated products such as drugs. If the
primary intended use of the product is achieved through chemical action or by being metabolized by the body, the product is usually a drug. If not, it is
generally a medical device.

Unless an exemption applies, a new medical device may not be marketed in the United States until it has been cleared through filing of a 510(k)

premarket notification, or 510(k), or approved by the FDA pursuant to a premarket approval application, or PMA. The information that must be submitted
to the FDA in order to obtain clearance or approval to market a new medical device varies depending on how the medical device is classified by the FDA.
Medical devices are classified into one of three classes on the basis of the controls deemed by the FDA to be necessary to reasonably ensure their safety
and effectiveness. Class I devices have the lowest level or risk associated with them, and are subject to general controls, including labeling, premarket
notification and adherence to the Quality System Regulation, or QSR. Class II devices are subject to general controls and special controls, including
performance standards. Class III devices, which have the highest level of risk associated with them, such as life sustaining, life supporting or some
implantable devices, or devices that have a new intended use, or use advanced technology that is not substantially equivalent to that of a legally marketed
device, are subject to most of the aforementioned requirements as well as to premarket approval.

A 510(k) must demonstrate that the proposed device is substantially equivalent to another legally marketed device, or predicate device, that did not

require premarket approval. In evaluating a 510(k), the FDA will determine whether the device has the same intended use as the predicate device, and
(a) has the same technological characteristics as the predicate device, or (b) has different technological characteristics, and (i) the data supporting
substantial equivalence contains information, including appropriate clinical or scientific data, if deemed necessary by the FDA, that demonstrates that the
device is as safe and as effective as a legally marketed device, and (ii) does not raise different questions of safety and effectiveness than the predicate
device. Most 510(k)s do not require clinical data for clearance, but the FDA may request such data. The FDA seeks to review and act on a 510(k) within 90
days of submission, but it may take longer if the agency finds that it requires more information to review the 510(k). If the FDA concludes that a new
device is not substantially equivalent to a predicate device, the new device will be classified in Class III and the manufacturer will be required to submit a
PMA to market the product. PMA applications are subject to an application fee. For federal fiscal year 2021, the standard fee is $365,657 and the small
business fee is $91,414.

Modifications to a 510(k)-cleared medical device may require the submission of another 510(k) or a PMA if the changes could significantly affect

safety or effectiveness or constitute a major change in the intended use of the device. Modifications to a 510(k)-cleared device frequently require the
submission of a traditional 510(k), but modifications meeting certain conditions may be candidates for FDA review under a Special 510(k). If a device
modification requires the submission of a 510(k), but the modification does not affect the intended use of the device or alter the fundamental technology of
the device, then summary information that results from the design control process associated with the cleared device can serve as the basis for clearing the
application. A Special 510(k) allows a manufacturer to declare conformance to design controls without providing new data. When the modification
involves a change in material, the nature of the “new” material will determine whether a traditional or Special 510(k) is necessary.

A clinical trial is typically required for a PMA application and, in a small percentage of cases, the FDA may require a clinical study in support of a
510(k) submission. A manufacturer that wishes to conduct a clinical study involving the device is subject to the FDA’s IDE regulation. The IDE regulation
distinguishes between significant and non-significant risk device studies and the procedures for obtaining approval to begin the study differ accordingly.
Also, some types of studies are exempt from the IDE regulations. A significant risk device presents a potential for serious risk to the health, safety, or
welfare of a subject. Significant risk devices are devices that are substantially important in diagnosing, curing, mitigating, or treating disease or in
preventing impairment to human health. Studies of devices that pose a significant risk require both FDA and an IRB approval prior to initiation of a clinical
study. Non-significant risk devices are devices that do not pose a significant risk to the human subjects. A non-significant risk device study requires only
IRB approval prior to initiation of a clinical study.

Review and Approval of Combination Products in the United States

Certain products may be comprised of components that would normally be regulated under different types of regulatory authorities, and frequently

by different Centers at the FDA. These products are known as combination products. Under regulations issued by the FDA, a combination product may be:

•

•

•

•

a product comprised of two or more regulated components that are physically, chemically, or otherwise combined or mixed and produced as a
single entity;

two or more separate products packaged together in a single package or as a unit and comprised of drug and device products;

a drug or device packaged separately that according to its investigational plan or proposed labeling is intended for use only with an approved
individually specified drug or device where both are required to achieve the intended use, indication, or effect and where upon approval of the
proposed product the labeling of the approved product would need to be changed, e.g., to reflect a change in intended use, dosage form,
strength, route of administration, or significant change in dose; or

any investigational drug or device packaged separately that according to its proposed labeling is for use only with another individually
specified investigational drug, device, or biological product where both are required to achieve the intended use, indication, or effect.

Under the FDCA, the FDA is charged with assigning a center with primary jurisdiction, or a lead center, for review of a combination product. That

determination is based on the “primary mode of action” of the combination product. Thus, if the primary mode of action of a device-drug combination
product is attributable to the drug product, the FDA Center responsible for premarket review of the drug product would have primary jurisdiction for the
combination product. The FDA has also established an Office of Combination Products to address issues surrounding combination products and provide
more certainty to the regulatory review process. That office serves as a focal point for combination product issues for agency reviewers and industry. It is
also responsible for developing guidance and regulations to clarify the regulation of combination products, and for assignment of the FDA center that has
primary jurisdiction for review of combination products where the jurisdiction is unclear or in dispute.

Review and Approval of Drug Products in the European Union

In order to market any product outside of the United States, a company must also comply with numerous and varying regulatory requirements of

other countries and jurisdictions regarding quality, safety and efficacy and governing, among other things, clinical trials, marketing authorization,
commercial sales and distribution of products. Whether or not it obtains FDA approval for a product, the company would need to obtain the necessary
approvals by the comparable foreign regulatory authorities before it can commence clinical trials or marketing of the product in those countries or
jurisdictions. The approval process ultimately varies between countries and jurisdictions and can involve additional product testing and additional
administrative review periods. The time required to obtain approval in other countries and jurisdictions might differ from and be longer than that required
to obtain FDA approval. Regulatory approval in one country or jurisdiction does not ensure regulatory approval in another, but a failure or delay in
obtaining regulatory approval in one country or jurisdiction may negatively impact the regulatory process in others.

Procedures Governing Approval of Drug Products in the European Union

Pursuant to the European Clinical Trials Directive, a system for the approval of clinical trials in the European Union has been implemented through

national legislation of the member states. Under this system, an applicant must obtain approval from the competent national authority of an E.U. member
state in which the clinical trial is to be conducted. Furthermore, the applicant may only start a clinical trial after a competent ethics committee has issued a
favorable opinion. Clinical trial application must be accompanied by an investigational medicinal product dossier with supporting information prescribed
by the European Clinical Trials Directive and corresponding national laws of the member states and further detailed in applicable guidance documents.

To obtain marketing approval of a product under European Union regulatory systems, an applicant must submit a marketing authorization

application, or MAA, either under a centralized or decentralized procedure. The centralized procedure provides for the grant of a single marketing
authorization by the European Commission that is valid for all E.U. member states. The centralized procedure is compulsory for specific products,
including for medicines produced by certain biotechnological processes, products designated as orphan medicinal products, advanced therapy products and
products with a new active substance indicated for the treatment of certain diseases. For products with a new active substance indicated for the treatment of
other diseases and products that are highly innovative or for which a centralized process is in the interest of patients, the centralized procedure may be
optional.

Under the centralized procedure, the Committee for Medicinal Products for Human Use, or the CHMP, established at the European Medicines
Agency, or EMA, is responsible for conducting the initial assessment of a product. The CHMP is also responsible for several post-authorization and
maintenance activities, such as the assessment of modifications or extensions to an

33

 
 
 
 
existing marketing authorization. Under the centralized procedure in the European Union, the maximum timeframe for the evaluation of an MAA is
210 days, excluding clock stops, when additional information or written or oral explanation is to be provided by the applicant in response to questions of
the CHMP. Accelerated evaluation might be granted by the CHMP in exceptional cases, when a medicinal product is of major interest from the point of
view of public health and in particular from the viewpoint of therapeutic innovation. In this circumstance, the EMA ensures that the opinion of the CHMP
is given within 150 days.

The decentralized procedure is available to applicants who wish to market a product in various E.U. member states where such product has not previously
received marketing approval in any E.U. member states. The decentralized procedure provides for approval by one or more other, or concerned, member states of
an assessment of an application performed by one member state designated by the applicant, known as the reference member state. Under this procedure, an
applicant submits an application based on identical dossiers and related materials, including a draft summary of product characteristics, and draft labeling and
package leaflet, to the reference member state and concerned member states. The reference member state prepares a draft assessment report and drafts of the
related materials within 210 days after receipt of a valid application. Within 90 days of receiving the reference member state’s assessment report and related
materials, each concerned member state must decide whether to approve the assessment report and related materials.

If a member state cannot approve the assessment report and related materials on the grounds of potential serious risk to public health, the disputed

points are subject to a dispute resolution mechanism and may eventually be referred to the European Commission, whose decision is binding on all member
states.

Clinical Trial Approval

Requirements for the conduct of clinical trials in the European Union including Good Clinical Practice, or GCP, are set forth in the Clinical Trials

Directive 2001/20/EC and the GCP Directive 2005/28/EC. Pursuant to Directive 2001/20/EC and Directive 2005/28/EC, as amended, a system for the
approval of clinical trials in the European Union has been implemented through national legislation of the E.U. member states. Under this system, approval
must be obtained from the competent national authority of each E.U. member state in which a study is planned to be conducted. To this end, a clinical trial
application is submitted, which must be supported by an investigational medicinal product dossier, or IMPD, and further supporting information prescribed
by Directive 2001/20/EC and Directive 2005/28/EC and other applicable guidance documents. Furthermore, a clinical trial may only be started after a
competent ethics committee has issued a favorable opinion on the clinical trial application in that country.

In April 2014, the European Union adopted a new Clinical Trials Regulation, (EU) No 536/2014, which is set to replace the current Clinical Trials
Directive 2001/20/EC. The new Clinical Trials Regulation will become directly applicable to and binding in all 28 E.U. member states without the need for any
national implementing legislation. It will overhaul the current system of approvals for clinical trials in the European Union. Specifically, the new legislation aims
at simplifying and streamlining the approval of clinical trials in the European Union. Under the new coordinated procedure for the approval of clinical trials, the
sponsor of a clinical trial will be required to submit a single application for approval of a clinical trial to a reporting E.U. member state (RMS) through a
European Union Portal. The submission procedure will be the same irrespective of whether the clinical trial is to be conducted in a single E.U. member state or in
more than one E.U. member state.  

The Regulation was published on June 16, 2014 but has not yet become effective.  In January 2020, the website of the European Commission
reported that the implementation of the Clinical Trials Regulation was dependent on the development of a fully functional clinical trials portal and database,
which would be confirmed by an independent audit, and that the new legislation would come into effect six months after the European Commission
publishes a notice of this confirmation. The website indicated that the audit was expected to commence in December 2020. In late 2020, the EMA indicated
that it plans to focus on the findings of a system audit; improving the usability, quality and stability of the clinical trial information system; and knowledge
transfer to prepare users and their organizations for the new clinical trial system.  The EMA has indicated that the system will go live in December 2021.

As in the United States, similar requirements for posting clinical trial information are present in the European Union (EudraCT) website:

https://eudract.ema.europa.eu/ and other countries.  

Pediatric Studies in the EU

Prior to obtaining a marketing authorization in the European Union, applicants must demonstrate compliance with all measures included in an
EMA-approved PIP covering all subsets of the pediatric population, unless the EMA has granted a product-specific waiver, a class waiver, or a deferral for
one or more of the measures included in the PIP. The respective requirements for all marketing authorization procedures are laid down in Regulation (EC)
No 1901/2006, the so-called Paediatric Regulation. This requirement also applies when a company wants to add a new indication, pharmaceutical form or
route of administration for a medicine that is already authorized. The Paediatric Committee of the EMA, or PDCO, may grant deferrals for some medicines,
allowing a company to delay development of the medicine for children until there is enough information to demonstrate its effectiveness and safety in
adults. The PDCO may also grant waivers when development of a medicine for children is not needed or is not appropriate, such as for diseases

34

that only affect the elderly population. Before an MAA can be filed, or an existing marketing authorization can be amended, the EMA determines that
companies actually comply with the agreed studies and measures listed in each relevant PIP.

PRIME Designation in the EU

In March 2016, the EMA launched an initiative to facilitate development of product candidates in indications, often rare, for which few or no

therapies currently exist. The PRIority MEdicines, or PRIME, scheme is intended to encourage drug development in areas of unmet medical need and
provides accelerated assessment of products representing substantial innovation reviewed under the centralized procedure. Products from small- and
medium-sized enterprises, or SMEs, may qualify for earlier entry into the PRIME scheme than larger companies. Many benefits accrue to sponsors of
product candidates with PRIME designation, including but not limited to, early and proactive regulatory dialogue with the EMA, frequent discussions on
clinical trial designs and other development program elements, and accelerated marketing authorization application assessment once a dossier has been
submitted. Importantly, a dedicated Agency contact and rapporteur from the CHMP or Committee for Advanced Therapies are appointed early in PRIME
scheme facilitating increased understanding of the product at EMA’s Committee level. A kick-off meeting initiates these relationships and includes a team
of multidisciplinary experts at the EMA to provide guidance on the overall development and regulatory strategies.

Data and Market Exclusivity in the European Union

In the European Union, new chemical entities qualify for eight years of data exclusivity upon marketing authorization and an additional two years of
market exclusivity. This data exclusivity, if granted, prevents regulatory authorities in the European Union from referencing the innovator’s data to assess a
generic (abbreviated) application for eight years, after which generic marketing authorization can be submitted, and the innovator’s data may be referenced,
but not approved for two years. The overall ten-year period will be extended to a maximum of eleven years if, during the first eight years of those ten years,
the marketing authorization holder obtains an authorization for one or more new therapeutic indications which, during the scientific evaluation prior to their
authorization, are held to bring a significant clinical benefit in comparison with existing therapies. Even if a compound is considered to be a new chemical
entity and the sponsor is able to gain the prescribed period of data exclusivity, another company nevertheless could also market another version of the
product if such company can complete a full MAA with a complete database of pharmaceutical tests, preclinical tests and clinical trials and obtain
marketing approval of its product.

In order to market any product outside of the United States, a company must also comply with numerous and varying regulatory requirements of

other countries and jurisdictions regarding quality, safety and efficacy and governing, among other things, clinical trials, marketing authorization,
commercial sales and distribution of drug products. Whether or not it obtains FDA approval for a product, the company would need to obtain the necessary
approvals by the comparable foreign regulatory authorities before it can commence clinical trials or marketing of the product in those countries or
jurisdictions. The approval process ultimately varies between countries and jurisdictions and can involve additional product testing and additional
administrative review periods. The time required to obtain approval in other countries and jurisdictions might differ from and be longer than that required
to obtain FDA approval. Regulatory approval in one country or jurisdiction does not ensure regulatory approval in another, but a failure or delay in
obtaining regulatory approval in one country or jurisdiction may negatively impact the regulatory process in others.

Periods of Authorization and Renewals

Marketing authorization is valid for five years in principle and the marketing authorization may be renewed after five years on the basis of a re-

evaluation of the risk-benefit balance by the EMA or by the competent authority of the authorizing member state. To this end, the marketing authorization
holder must provide the EMA or the competent authority with a consolidated version of the file in respect of quality, safety and efficacy, including all
variations introduced since the marketing authorization was granted, at least six months before the marketing authorization ceases to be valid. Once
renewed, the marketing authorization is valid for an unlimited period, unless the European Commission or the competent authority decides, on justified
grounds relating to pharmacovigilance, to proceed with one additional five-year renewal. Any authorization which is not followed by the actual placing of
the drug on the European Union market (in case of centralized procedure) or on the market of the authorizing member state within three years after
authorization ceases to be valid (the so-called sunset clause).

Orphan Drug Designation and Exclusivity

Regulation 141/2000 provides that a drug shall be designated as an orphan drug if its sponsor can establish: that the product is intended for the
diagnosis, prevention or treatment of a life-threatening or chronically debilitating condition affecting not more than five in ten thousand persons in the
European Community when the application is made, or that the product is intended for the diagnosis, prevention or treatment of a life-threatening, seriously
debilitating or serious and chronic condition in the European Community and that without incentives it is unlikely that the marketing of the drug in the
European Community would generate sufficient return to justify the necessary investment. For either of these conditions, the applicant must demonstrate
that there exists no satisfactory method of diagnosis, prevention or treatment of the condition in question that has been authorized in the European
Community or, if such method exists, the drug will be of significant benefit to those affected by that condition.

35

Regulation 847/2000 sets out criteria and procedures governing designation of orphan drugs in the European Union. Specifically, an application for

designation as an orphan product can be made any time prior to the filing of an application for approval to market the product. Marketing authorization for an
orphan drug leads to a ten-year period of market exclusivity. This period may, however, be reduced to six years if, at the end of the fifth year, it is established that
the product no longer meets the criteria for orphan drug designation, for example because the product is sufficiently profitable not to justify market exclusivity.
Market exclusivity can be revoked only in very selected cases, such as consent from the marketing authorization holder, inability to supply sufficient quantities of
the product, demonstration of “clinically relevant superiority” by a similar medicinal product, or, after a review by the Committee for Orphan Medicinal
Products, requested by a member state in the fifth year of the marketing exclusivity period (if the designation criteria are believed to no longer apply). Medicinal
products designated as orphan drugs pursuant to Regulation 141/2000 shall be eligible for incentives made available by the European Community and by the
member states to support research into, and the development and availability of, orphan drugs.

Pediatric Exclusivity in the EU

If an applicant obtains a marketing authorization in all EU Member States, or a marketing authorization granted in the centralized procedure by the
European Commission, and the study results for the pediatric population are included in the product information, even when negative, the medicine is then
eligible for an additional six-month period of qualifying patent protection through extension of the term of the Supplementary Protection Certificate, or
SPC

Brexit and the Regulatory Framework in the United Kingdom

On June 23, 2016, the electorate in the United Kingdom (U.K.) voted in favor of leaving the European Union (commonly referred to as “Brexit”).

Following protracted negotiations, the United Kingdom left the European Union on January 31, 2020. Under the withdrawal agreement, there is a
transitional period until December 31, 2020 (extendable up to two years). On December 24, 2020, the United Kingdom and the European Union entered
into a Trade and Cooperation Agreement. The agreement sets out certain procedures for approval and recognition of medical products in each jurisdiction.
Since the regulatory framework for pharmaceutical products in the United Kingdom covering quality, safety, and efficacy of pharmaceutical products,
clinical trials, marketing authorization, commercial sales, and distribution of pharmaceutical products is derived from European Union directives and
regulations, Brexit could materially impact the future regulatory regime that applies to products and the approval of product candidates in the United
Kingdom, as the United Kingdom legislation now has the potential to diverge from European Union legislation. It remains to be seen how Brexit will
impact regulatory requirements for product candidates and products in the UK in the long-term. The MHRA has recently published detailed guidance for
industry and organizations to follow from January 1, 2021 now the transition period is over, which will be updated as the UK’s regulatory position on
medicinal products evolves over time.

Furthermore, while the Data Protection Act of 2018 in the United Kingdom that “implements” and complements the European Union’s General Data

Protection Regulation, or GDPR, has achieved Royal Assent on May 23, 2018 and is now effective in the United Kingdom, it is still unclear whether
transfer of data from the European Economic Area, or EEA, to the United Kingdom will remain lawful under GDPR. The Trade and Cooperation
Agreement provides for a transitional period during which the United Kingdom will be treated like an European Union member state in relation to
processing and transfers of personal data for four months from January 1, 2021.  This may be extended by two further months. After such period, the
United Kingdom will be a “third country” under the GDPR unless the European Commission adopts an adequacy decision in respect of transfers of
personal data to the United Kingdom. The United Kingdom has already determined that it considers all of the EU 27 and EEA member states to be
adequate for the purposes of data protection, ensuring that data flows from the United Kingdom to the EU/EEA remain unaffected.

General Data Protection Regulation

The collection, use, disclosure, transfer, or other processing of personal data regarding individuals in the EU, including personal health data, is
subject to the EU General Data Protection Regulation (GDPR), which became effective on May 25, 2018. The GDPR is wide-ranging in scope and imposes
numerous requirements on companies that process personal data, including requirements relating to processing health and other sensitive data, obtaining
consent of the individuals to whom the personal data relates, providing information to individuals regarding data processing activities, implementing
safeguards to protect the security and confidentiality of personal data, providing notification of data breaches, and taking certain measures when engaging
third-party processors. The GDPR also imposes strict rules on the transfer of personal data to countries outside the EU, including the U.S., and permits data
protection authorities to impose large penalties for violations of the GDPR, including potential fines of up to €20 million or 4% of annual global revenues,
whichever is greater. The GDPR also confers a private right of action on data subjects and consumer associations to lodge complaints with supervisory
authorities, seek judicial remedies, and obtain compensation for damages resulting from violations of the GDPR. Compliance with the GDPR will be a
rigorous and time-intensive process that may increase the cost of doing business or require companies to change their business practices to ensure full
compliance.

Pharmaceutical Coverage, Pricing and Reimbursement

Significant uncertainty exists as to the coverage and reimbursement status of products approved by the FDA and other government authorities. Sales
of products will depend, in part, on the extent to which third-party payors, including government health programs in the United States such as Medicare and
Medicaid, commercial health insurers and managed care organizations, provide coverage, and establish adequate reimbursement levels for, such products.
The process for determining whether a payor will provide coverage for a product may be separate from the process for setting the price or reimbursement
rate that the payor will pay for the product once coverage is approved. Third-party payors are increasingly challenging the prices charged, examining the
medical necessity, and reviewing the cost-effectiveness of medical products and services and imposing controls to manage costs. Third-party payors may
limit coverage to specific products on an approved list, or formulary, which might not include all of the approved products for a particular indication.

In order to secure coverage and reimbursement for any product that might be approved for sale, a company may need to conduct expensive
pharmacoeconomic, health outcome studies in order to demonstrate the medical necessity, quality of life benefits, and cost-effectiveness of the product, in
addition to the costs required to obtain FDA or other comparable regulatory approvals. Nonetheless, product candidates may not be considered medically
necessary or cost effective in light of cost-benefit analysis. Additionally, a payor’s decision to provide coverage for a drug product does not imply that an
adequate reimbursement rate will be approved. Further, one payor’s determination to provide coverage for a drug product does not assure that other payors
will also provide coverage for the drug product. Third-party reimbursement may not be sufficient to maintain price levels high enough to realize an
appropriate return on investment in product development.

The containment of healthcare costs also has become a priority of federal, state and foreign governments and the prices of drugs have been a focus

in this effort. Governments have shown significant interest in implementing cost-containment programs, including price controls, restrictions on
reimbursement and requirements for substitution of generic products. Adoption of price controls and cost-containment measures, and adoption of more
restrictive policies in jurisdictions with existing controls and measures, could further limit our net revenue and results. Coverage policies and third-party
reimbursement rates may change at any time. Even if favorable coverage and reimbursement status is attained for one or more products for which a
company or its collaborators receive regulatory approval, less favorable coverage policies and reimbursement rates may be implemented in the future.

Outside the United States, ensuring adequate coverage and payment for our product candidates will face challenges. Pricing of prescription

pharmaceuticals is subject to governmental control in many countries. Pricing negotiations with governmental authorities can extend well beyond the
receipt of regulatory marketing approval for a product and may require us to conduct studies that compare the cost effectiveness of our product candidates
or products to other available therapies. The conduct of such studies could be expensive and result in delays in our commercialization efforts.

Pricing and reimbursement schemes vary widely from country to country. Some countries provide that drug products may be marketed only after a
reimbursement price has been agreed. Some countries may require the completion of additional studies that compare the cost-effectiveness of a particular
drug candidate to currently available therapies in order to obtain reimbursement. For example, the European Union provides options for its member states
to restrict the range of drug products for which their national health insurance systems provide reimbursement and to control the prices of medicinal
products for human use. European Union member states may approve a specific price for a drug product or it may instead adopt a system of direct or
indirect controls on the profitability of the company placing the drug product on the market. Other member states allow companies to fix their own prices
for drug products but monitor and control company profits and issue guidance to prescribers. The downward pressure on health care costs in general,
particularly prescription drugs, has become intense. As a result, increasingly high barriers are being erected to the entry of new products. In addition,
reference pricing and cross-border imports from low-priced markets exert competitive pressure that may reduce pricing within a country. Any country that
has price controls or reimbursement limitations for drug products may not allow favorable reimbursement and pricing arrangements.  

Healthcare Law and Regulation

Healthcare providers and third-party payors play a primary role in the recommendation and prescription of drug products that are granted regulatory

approval. Arrangements with providers, consultants, third-party payors and customers are subject to broadly applicable fraud and abuse and other
healthcare laws and regulations that may constrain our business and/or financial arrangements. Such restrictions under applicable federal and state
healthcare laws and regulations, include the following:

•

the federal Anti-Kickback Statute, which prohibits, among other things, persons and entities from knowingly and willfully soliciting, offering,
receiving or providing remuneration (including any kickback, bribe or rebate), directly or indirectly, in cash or in kind, to induce or reward
either the referral of an individual for, or the purchase, lease or order of, any good or service, for which payment may be made, in whole or in
part, under a federal healthcare program such as Medicare and Medicaid;

37

 
•

•

•

•

•

•

the federal civil and criminal false claims laws, including the civil False Claims Act, and civil monetary penalties laws, which prohibit
individuals or entities from, among other things, knowingly presenting, or causing to be presented, to the federal government, claims for
payment that are false or fraudulent or making a false statement to avoid, decrease or conceal an obligation to pay money to the federal
government;

the federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, which created additional federal criminal laws that
prohibit, among other things, knowingly and willingly executing, or attempting to execute, a scheme or making false statements in connection
with the delivery of or payment for health care benefits, items, or services;

HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act and its implementing regulations, which
also imposes obligations, including mandatory contractual terms, with respect to safeguarding the privacy, security and transmission of
individually identifiable health information on covered entities and their business associates that associates that perform certain functions or
activities that involve the use or disclosure of protected health information on their behalf;

the Foreign Corrupt Practices Act, or FCPA, which prohibits companies and their intermediaries from making, or offering or promising to
make improper payments to non-U.S. officials for the purpose of obtaining or retaining business or otherwise seeking favorable treatment;

the federal transparency requirements known as the federal Physician Payments Sunshine Act, under the Patient Protection and Affordable
Care Act, as amended by the Health Care Education Reconciliation Act, or collectively the ACA, which requires certain manufacturers of
drugs, devices, biologics and medical supplies for which payment is available under Medicare, Medicaid, or the Children’s Health Insurance
Program, with specific exceptions, to report annually to the Centers for Medicare & Medicaid Services, or CMS, within the U.S. Department
of Health and Human Services, information related to payments and other transfers of value to physicians and teaching hospitals and
information regarding ownership and investment interests held by physicians and their immediate family members; and

analogous state and foreign laws and regulations, such as state anti-kickback and false claims laws, which may apply to healthcare items or
services that are reimbursed by non-governmental third-party payors, including private insurers.

Some state laws require pharmaceutical companies to comply with the pharmaceutical industry’s voluntary compliance guidelines and the relevant

compliance guidance promulgated by the federal government in addition to requiring drug manufacturers to report information related to payments to
physicians and other health care providers or marketing expenditures. State and foreign laws also govern the privacy and security of health information in
some circumstances, many of which differ from each other in significant ways and often are not preempted by HIPAA, thus complicating compliance
efforts.

Healthcare Reform

A primary trend in the United States healthcare industry and elsewhere is cost containment. There have been a number of federal and state proposals
during the last few years regarding the pricing of pharmaceutical and biopharmaceutical products, limiting coverage and reimbursement for drugs and other
medical products, government control and other changes to the healthcare system in the United States.

In March 2010, the United States Congress enacted the Affordable Care Act, or ACA, which, among other things, includes changes to the coverage

and payment for drug products under government health care programs. In addition, other legislative changes have been proposed and adopted since the
ACA was enacted. In August 2011, the Budget Control Act of 2011, among other things, created measures for spending reductions by Congress. A Joint
Select Committee on Deficit Reduction, tasked with recommending a targeted deficit reduction of at least $1.2 trillion for the years 2013 through 2021, was
unable to reach required goals, thereby triggering the legislation’s automatic reduction to several government programs. These changes included aggregate
reductions to Medicare payments to providers of up to 2% per fiscal year, which went into effect in April 2013 and will remain in effect through 2030
under the Coronavirus Aid, Relief, and Economic Security Act, or the CARES Act.  The American Taxpayer Relief Act of 2012, among other things,
reduced Medicare payments to several providers and increased the statute of limitations period for the government to recover overpayments to providers
from three to five years. These laws may result in additional reductions in Medicare and other healthcare funding and otherwise affect the prices we may
obtain for any of our product candidates for which we may obtain regulatory approval or the frequency with which any such product candidate is prescribed
or used.

Since enactment of the ACA, there have been, and continue to be, numerous legal challenges and Congressional actions to repeal and replace

provisions of the law. For example, with enactment of the Tax Cuts and Jobs Act of 2017, which was signed by President Trump on December 22, 2017,
Congress repealed the “individual mandate.” The repeal of this provision, which requires most Americans to carry a minimal level of health insurance,
became effective in 2019. Further, on December 14, 2018, a U.S. District Court judge in the Northern District of Texas ruled that the individual mandate
portion of the ACA is an essential and inseverable feature of the ACA, and therefore because the mandate was repealed as part of the Tax Cuts and Jobs
Act, the remaining provisions of the ACA are invalid as well. On December 18, 2019, the Court of Appeals for the Fifth Circuit court affirmed the lower

38

 
 
 
 
 
 
court’s ruling that the individual mandate portion of the ACA is unconstitutional and it remanded the case to the district court for reconsideration of the
severability question and additional analysis of the provisions of the ACA.  Thereafter, the U.S. Supreme Court agreed to hear this case. Oral argument in
the case took place on November 10, 2020.  On February 10, 2021, the Biden Administration withdrew DOJ’s support for this lawsuit.  A ruling by the
Court is expected sometime this year. Litigation and legislation over the ACA are likely to continue, with unpredictable and uncertain results.

The Trump Administration also took executive actions to undermine or delay implementation of the ACA, including  directing federal agencies with
authorities and responsibilities under the ACA to waive, defer, grant exemptions from, or delay the implementation of any provision of the ACA that would
impose a fiscal or regulatory burden on states, individuals, healthcare providers, health insurers, or manufacturers of pharmaceuticals or medical
devices.  On January 28, 2021, however, President Biden rescinded those orders and issued a new Executive Order which directs federal agencies to
reconsider rules and other policies that limit Americans’ access to health care, and consider actions that will protect and strengthen that access.  Under this
Order, federal agencies are directed to re-examine: policies that undermine protections for people with pre-existing conditions, including complications
related to COVID-19; demonstrations and waivers under Medicaid and the ACA that may reduce coverage or undermine the programs, including work
requirements; policies that undermine the Health Insurance Marketplace or other markets for health insurance; policies that make it more difficult to enroll
in Medicaid and the ACA; and policies that reduce affordability of coverage or financial assistance, including for dependents.

The costs of prescription pharmaceuticals have also been the subject of considerable discussion in the United States To date, there have been several
recent U.S. congressional inquiries, as well as proposed and enacted state and federal legislation designed to, among other things, bring more transparency
to drug pricing, review the relationship between pricing and manufacturer patient programs, reduce the costs of drugs under Medicare and reform
government program reimbursement methodologies for drug products.  To those ends, the Trump Administration issued five executive orders intended to
lower the costs of prescription drug products but it is unclear whether, and to what extent, these orders will remain in force under the Biden
Administration.  Further, on September 24, 2020, the Trump Administration finalized a rulemaking allowing states or certain other non-federal government
entities to submit importation program proposals to the FDA for review and approval. Applicants are required to demonstrate that their importation plans
pose no additional risk to public health and safety and will result in significant cost savings for consumers.  The FDA has issued draft guidance that would
allow manufacturers to import their own FDA-approved drugs that are authorized for sale in other countries (multi-market approved products).  

At the state level, individual states are increasingly aggressive in passing legislation and implementing regulations designed to control

pharmaceutical and biological product pricing, including price or patient reimbursement constraints, discounts, restrictions on certain product access and
marketing cost disclosure and transparency measures, and, in some cases, designed to encourage importation from other countries and bulk purchasing. In
addition, regional health care organizations and individual hospitals are increasingly using bidding procedures to determine what pharmaceutical products
and which suppliers will be included in their prescription drug and other health care programs. These measures could reduce the ultimate demand for our
products, once approved, or put pressure on our product pricing. We expect that additional state and federal healthcare reform measures will be adopted in
the future, any of which could limit the amounts that federal and state governments will pay for healthcare products and services, which could result in
reduced demand for our product candidates or additional pricing pressures.

Employees

As of December 31, 2020, we had 374 full-time or part-time employees, including 5 employees with M.D./Ph.D. degrees, 7 employees with an

M.D. degree and 43 employees with Ph.D. degrees. None of our employees are represented by labor unions or covered by collective bargaining
agreements. We consider the relationship with our employees to be good.

We recognize that attracting, motivating and retaining talented employees is vital to our success. We value the health and wellness of our

employees and their families. It is our goal to deliver innovative programs that provide choice, quality, and value. We aim to create an equitable, inclusive
and empowering environment in which our employees can grow and advance their careers, with the overall goal of developing, expanding and retaining our
workforce to support our current pipeline and future business goals. Our success also depends on our ability to attract, engage and retain a diverse group of
employees. Our efforts to recruit and retain a diverse and passionate workforce include providing competitive compensation and benefits packages.

Our human capital resources objectives include, as applicable, identifying, recruiting, retaining, incentivizing and integrating our existing and

additional employees. The principal purposes of our equity incentive plans are to attract, retain and motivate selected employees, consultants and directors
through the granting of stock-based compensation awards. We offer a comprehensive benefits program that provides resources to help employees manage
their health, finances, and life outside of work.

Item 1A. Risk Factors.

Careful consideration should be given to the following risk factors, in addition to the other information set forth in this Annual Report on Form 10-K and
in other documents that we file with the SEC, in evaluating our company and our business. Investing in our common stock involves a high degree of risk. If
any of the following risks actually occur, our business, financial condition, results of operations and future growth prospects could be materially and
adversely affected.  

Risks Related to Our Financial Position and Need for Additional Capital

We have incurred significant losses since inception, expect to incur significant and increasing losses for at least the next several years, and may never
achieve or maintain profitability.

We have incurred significant annual net operating losses in every year since our inception. We expect to continue to incur significant and increasing

net operating losses for at least the next several years. Our net losses were $344.9 million, $304.7 million and $127.5 million for the years ended
December 31, 2020, 2019 and 2018, respectively. As of December 31, 2020, we had an accumulated deficit of $926.3 million. We have not generated any
revenues from product sales, have not completed the development of any product candidate and may never have a product candidate approved for
commercialization. We have financed our operations to date primarily through the sale of our common stock in our initial public offering and subsequent
follow-on offerings, the sale of convertible notes, private placements of our preferred stock prior to our initial public offering, the development funding
agreement with SFJ Pharmaceuticals Group, or SFJ, the collaboration agreement with Swedish Orphan Biovitrum AB (Publ), or Sobi, borrowings under a
term loan facility and the issuance and sale of a promissory note. We have devoted substantially all of our financial resources and efforts to research and
development, including preclinical studies and our clinical trials. Our net losses may fluctuate significantly from quarter to quarter and year to year. Net
losses and negative cash flows have had, and will continue to have, an adverse effect on our stockholders’ equity and working capital.

We expect to continue to incur significant expenses and increasing operating losses for the foreseeable future. We anticipate that our expenses will

increase substantially if and as we:

•

•

•

•

•

•

continue to develop and conduct clinical trials with our lead product candidate, pegcetacoplan, and APL-9;

initiate and continue research and preclinical and clinical development efforts for any future product candidates;

seek to identify and develop additional product candidates for complement-dependent diseases;

seek regulatory and marketing approvals for our product candidates that successfully complete clinical trials, if any;

establish sales, marketing, distribution and other commercial infrastructure to commercialize any products for which we may obtain
marketing approval;

require the manufacture of larger quantities of product candidates for clinical development and, potentially, commercialization;

40

 
 
 
 
 
 
•

•

•

•

maintain, expand and protect our intellectual property portfolio;

hire and retain additional personnel, such as clinical, quality control and scientific personnel;

add operational, financial and management information systems and personnel, including personnel to support our product development and
help us comply with our obligations as a public company; and

add equipment and physical infrastructure to support our research and development programs.

Our ability to become and remain profitable depends on our ability to generate revenue. We do not expect to generate significant revenue unless and

until we are, or our collaborators, including Sobi, are able to obtain marketing approval for, and successfully commercialize, one or more of our product
candidates. Successful commercialization will require achievement of key milestones, including completing clinical trials of our product candidates,
obtaining marketing approval for these product candidates, manufacturing, marketing and selling those products for which we, or any of our collaborators,
may obtain marketing approval, satisfying any post-marketing requirements and obtaining reimbursement for our products from private insurance or
government payors. Because of the uncertainties and risks associated with these activities, we are unable to accurately predict the timing and amount of
revenues, and if or when we might achieve profitability. We and any collaborators may never succeed in these activities and, even if we do, or any
collaborators do, we may never generate revenues that are large enough for us to achieve profitability. Even if we do achieve profitability, we may not be
able to sustain or increase profitability on a quarterly or annual basis. Our failure to become and remain profitable would decrease the value of our
company and could impair our ability to raise capital, expand our business, maintain our research and development efforts, diversify our pipeline of product
candidates or continue our operations. A decline in the value of our company could cause our stockholders to lose all or part of their investment.

We have not yet successfully obtained marketing approvals nor commercialized pharmaceutical products, which may make it difficult to evaluate our
future prospects.  

Our operations to date have been limited to financing and staffing our company, developing our technology and conducting preclinical research and
Phase 1, Phase 2 and Phase 3 clinical trials for our product candidates. However, although we have begun planning commercial activities, we have not yet
demonstrated an ability to successfully obtain marketing approvals, manufacture a commercial-scale product, or arrange for a third party to do so on our
behalf, or conduct sales and marketing activities necessary for successful product commercialization. Accordingly, our stockholders should consider our
prospects in light of the costs, uncertainties, delays and difficulties frequently encountered by clinical-stage biopharmaceutical companies such as ours.
Any predictions made about our future success or viability may not be as accurate as they could be if we had a longer operating history or a history of
successfully developing and commercializing pharmaceutical products.

We may encounter unforeseen expenses, difficulties, complications, delays and other known or unknown factors in achieving our business

objectives. We will need to transition from a company with a development focus to a company capable of supporting commercial activities. We may not be
successful in such a transition.

We expect our financial condition and operating results to continue to fluctuate significantly from quarter to quarter and year to year due to a variety

of factors, many of which are beyond our control. Accordingly, our stockholders should not rely upon the results of any quarterly or annual periods as
indications of future operating performance.

We will need substantial additional funding to allow us to support both the systemic and ophthalmological programs through commercial launch, and
if we are unable to raise capital when needed, we could be forced to delay, reduce or eliminate our product development programs or commercialization
efforts.

Developing pharmaceutical products, including conducting preclinical studies and clinical trials, is a very time-consuming, expensive and uncertain

process that takes years to complete. We have consumed substantial amounts of cash since our inception. For example, in the years ended December 31,
2020, 2019 and 2018, we used net cash of $160.5 million, $211.1 million and $131.2 million respectively, in our operating activities substantially all of
which related to research and development activities. As of December 31, 2020, our cash, cash equivalents and marketable securities were $877.6 million.
We expect our expenses to increase in connection with our ongoing activities, particularly as we initiate new clinical trials of, initiate new research and
preclinical development efforts for, seek marketing approval for and prepare for commercialization of, our product candidates. In addition, if we obtain
marketing approval for pegcetacoplan or any of our other product candidates, we may incur significant commercialization expenses related to product sales,
marketing, manufacturing and distribution to the extent that such sales, marketing, manufacturing and distribution are not the responsibility of the
collaborator. Furthermore, we continue to incur significant costs associated with operating as a public company. Accordingly, we will need to obtain
substantial additional funding in connection with our continuing operations, particularly if we commercialize the ophthalmological program outside the
United States without a collaborator or if we fail to establish substantial commercial sales of systemic pegcetacoplan. If we are unable to raise capital when
needed or on attractive

terms, we may be forced to delay, reduce or eliminate our research and development programs or any future commercialization efforts.

We will be required to expend significant funds in order to advance the development of pegcetacoplan in multiple disease areas, as well as other
product candidates we may seek to develop. In addition to our collaboration agreement with Sobi, we may seek one or more additional collaborators for
future development of our product candidates for one or more indications. However, we may not be able to enter into an additional collaboration for any of
our product candidates for such indications on suitable terms, on a timely basis or at all. Accordingly, we may be required to obtain further funding through
public or private equity offerings, debt financings, collaborations and licensing arrangements or other sources to achieve our business objectives. We do not
have any committed external source of funds other than Sobi’s reimbursement obligations under the collaboration agreement. Adequate additional
financing may not be available to us on acceptable terms, or at all. Our failure to raise capital as and when needed would have a negative impact on our
financial condition and our ability to pursue our business strategy.

We believe that our existing cash, cash equivalents and marketable securities, along with the committed development reimbursement payments from
Sobi, will enable us to fund our operating expenses and capital expenditure requirements at least into the second half of 2022. Our estimate as to how long
we expect our cash, cash equivalents and marketable securities to be able to continue to fund our operations is based on assumptions that may prove to be
wrong, and we could use our available capital resources sooner than we currently expect. Although we expect that our cash, cash equivalents and
marketable securities will be sufficient to allow us to complete the DERBY and OAKS clinical trials, we do not believe they will be sufficient to allow us
to support both the systemic and ophthalmological pegcetacoplan programs through commercial launch. Further, changing circumstances, some of which
may be beyond our control, could cause us to consume capital significantly faster than we currently anticipate, and we may need to seek additional funds
sooner than planned. Our future funding requirements, will depend on many factors, including:

•

•

•

•

•

•

•

•

•

•

•

•

•

the scope, progress, timing, costs and results of clinical trials of, and research and preclinical development efforts for, pegcetacoplan, APL-9
and future product candidates;

our ability to maintain a productive collaborative relationship with Sobi with respect to pegcetacoplan, including our ability to achieve
milestone payments under our agreement with Sobi;

our ability to identify additional collaborators for any of our product candidates and the terms and timing of any collaboration agreement that
we may establish for the development and any commercialization of such product candidates;

the number and characteristics of future product candidates that we pursue and their development requirements;

the outcome, timing and costs of clinical trials and of seeking regulatory approvals of pegcetacoplan and other product candidates we may
pursue;

the costs of commercialization activities for any of our product candidates that receive marketing approval to the extent such costs are not the
responsibility of our collaborators, including the costs and timing of establishing product sales, marketing, distribution and manufacturing
capabilities;

subject to receipt of marketing approval, revenue, if any, received from commercial sales of pegcetacoplan and other product candidates;

our headcount growth and associated costs as we expand our research and development and establish a commercial infrastructure;

the costs of preparing, filing and prosecuting patent applications, maintaining and protecting our intellectual property rights and defending
against intellectual property related claims;

the effect of competing technological and market developments;

the effect of the COVID-19 pandemic on the healthcare system and the economy generally and on our clinical trials and other operations
specifically;

our ability to obtain adequate reimbursement for any product we commercialize; and

the costs of operating as a public company.

Raising additional capital may cause dilution to our stockholders, restrict our operations or require us to relinquish rights to our technologies or
product candidates.

We expect our expenses to increase in connection with our planned operations. To the extent that we raise additional capital through the sale of

common stock, convertible securities or other equity securities, the ownership interest of our then-existing stockholders may be diluted, and the terms of
these securities could include liquidation or other preferences and anti-dilution protections that could adversely affect the rights of our common
stockholders. In addition, additional debt financing, if available,

42

 
 
 
 
 
 
 
 
 
 
 
 
 
would result in fixed payment obligations and may involve agreements that include grants of security interests on our assets and restrictive covenants that
limit our ability to take specific actions, such as incurring additional debt, making capital expenditures, creating liens, redeeming stock or declaring
dividends, that could adversely impact our ability to conduct our business.

For example, under our development funding agreement with SFJ, as amended, we have agreed that following regulatory approval by the U.S. Food

and Drug Administration, or FDA, or the European Medicines Agency, or EMA, for the use of pegcetacoplan as a treatment for paroxysmal nocturnal
hemoglobinuria, or PNH, we will pay to SFJ an initial payment of up to $5.0 million (or up to a total of $10.0 million if regulatory approval is granted by
the FDA and the EMA) and then up to an additional $226.0 million in the aggregate (or up to $452.0 million if regulatory approval is granted by the FDA
and the EMA) in six additional annual payments with the majority of the payments being made from the third anniversary to the sixth anniversary of
regulatory approval. In September 2020, we submitted an NDA, to the FDA and a marketing approval authorization, or MAA, to the EMA for
pegcetacoplan for the treatment of PNH. Additionally, we granted a security interest in all of our assets, excluding our intellectual property and license
agreements to which we are a party. In connection with the grant of the security interest, we agreed to certain affirmative and negative covenants, including
restrictions on our ability to pay dividends, incur additional debt or enter into licensing transactions with respect to our intellectual property other than
specified types of licenses.

Future debt securities or other financing arrangements could contain similar or more restrictive negative covenants. In addition, securing financing
could require a substantial amount of time and attention from our management and may divert a disproportionate amount of their attention away from day-
to-day activities, which may adversely affect our management’s ability to oversee the development of our product candidates.

In January 2021, we closed privately negotiated exchanges with holders of our outstanding convertible notes issued in September 2019, or the 2019

Convertible Notes, under which we issued approximately 3.9 million shares of common stock in exchange for approximately $126.1 million in aggregate
principal amount of 2019 Convertible Notes.  The effective price per share of the common stock issued in the exchange transactions was lower than the
trading price of the Company’s common stock on the Nasdaq market at the time of settlement of the exchanges. We may in the future exchange additional
principal amount of our Convertible Notes and the effective price per share of the common stock may be lower than the trading price at such time.

If we raise additional funds through collaborations or marketing, distribution or licensing arrangements with third parties, we may have to relinquish
valuable rights to our technologies, future revenue streams or product candidates or grant licenses on terms that may not be favorable to us. If we are unable
to raise additional funds when needed, we may be required to delay, limit, reduce or terminate our product development or future commercialization efforts
or grant rights to develop and market product candidates that we would otherwise prefer to develop and market ourselves.

If we receive regulatory approval for the use of pegcetacoplan as a treatment for PNH or if our agreement with SFJ is terminated prior to receiving
such approval in specified circumstances, we will be required to make substantial payments to SFJ pursuant to our development funding agreement. If
we do not have sufficient funding or cash flow from our business to meet our payment obligations under the development funding agreement, SFJ
could exercise its remedies as a holder of a first priority security interest in our assets and our business could be materially harmed.

We submitted an NDA to the FDA and a MAA to the EMA for pegcetacoplan for the treatment of PNH in September 2020. If we receive regulatory

approval for the use of pegcetacoplan as a treatment for PNH, we will be required to make substantial payments to SFJ pursuant to our development
funding agreement. In addition, if the agreement is terminated prior to obtaining regulatory approval for the treatment of PNH, under specified
circumstances, we also will be required to make substantial payments to SFJ. Our ability to make these required payments depends on our future
performance and the future performance of Sobi, which is subject to economic, financial, competitive and other factors beyond our control. Our business
may generate cash flow from operations in the future sufficient to meet our obligations under the development funding agreement. If we are unable to
generate such cash flow or to obtain additional funding through public or private equity offerings, debt financings, collaborations and licensing
arrangements or other sources on acceptable terms or at all, we could default on our payment obligations to SFJ.

Our payment obligations to SFJ could have significant consequences for our security holders and our business, results of operations and financial

condition by, among other things:

•

•

•

limiting our ability to obtain additional financing;

requiring the dedication of a substantial portion of our cash flow from operations to service our meet our obligations under the development
funding agreement, which will reduce the amount of cash available for other purposes; and

limiting our flexibility to plan for, or react to, changes in our business;

43

 
 
 
Our business may not generate sufficient funds, and we may otherwise be unable to maintain sufficient cash reserves, to pay amounts due to SFJ,

and our cash needs may increase in the future.

We have granted SFJ a first priority security interest in all of our assets other than our intellectual property and the license agreements to which we

are a party. If we are unable to meet our payment obligations to SFJ, SFJ may exercise its remedies as a holder of a first priority security interest, which
would result in a loss of our assets and our business would be materially harmed.

Our indebtedness could limit the cash flow available for our operations, expose us to risks that could adversely affect our business, financial condition
and results of operations and impair our ability to satisfy our obligations under the Convertible Notes.

We incurred an aggregate of $520.0 million of indebtedness as a result of the issuance of convertible notes in September 2019 and May 2020, or the

Convertible Notes, of which an aggregate of approximately $393.9 million is outstanding and held by third parties as of the date of this Annual Report on
Form 10-K.  We issued approximately 3.9 million shares of our common stock in exchange for approximately $126.1 million of 2019 Convertible Notes in
January 2021. We may also incur additional indebtedness to meet future financing needs. Our indebtedness could have significant negative consequences
for our security holders and our business, results of operations and financial condition by, among other things:

•

•

•

•

•

•

increasing our vulnerability to adverse economic and industry conditions;

limiting our ability to obtain additional financing;

requiring the dedication of a substantial portion of our cash flow from operations to service our indebtedness, which will reduce the amount of
cash available for other purposes;

limiting our flexibility to plan for, or react to, changes in our business;

diluting the interests of our existing stockholders as a result of issuing shares of our common stock upon conversion of the Convertible Notes;
and

placing us at a possible competitive disadvantage with competitors that are less leveraged than us or have better access to capital.

Our business may not generate sufficient funds, and we may otherwise be unable to maintain sufficient cash reserves, to pay amounts due under the

Convertible Notes, and our cash needs may increase in the future.

Servicing the Convertible Notes will require a significant amount of cash, and we may not have sufficient cash flow from our business to make
payments on the Convertible Notes.

Our ability to make scheduled payments of the principal of, to pay interest on or to refinance the Convertible Notes depends on our future
performance, which is subject to economic, financial, competitive and other factors beyond our control. Our business may not generate cash flow from
operations in the future sufficient to service the Convertible Notes. If we are unable to generate cash flow, we may be required to adopt one or more
alternatives, such as selling assets, restructuring debt or obtaining additional equity capital on terms that may be unfavorable to us or highly dilutive. Our
ability to refinance our indebtedness will depend on the capital markets and our financial condition at the time we seek to refinance such indebtedness. We
may not be able to engage in any of these activities or engage in these activities on desirable terms, which could result in a default on our debt obligations.

We may not have the ability to raise the funds necessary to settle conversions of the Convertible Notes in cash or to repurchase the Convertible Notes
upon a fundamental change, and our future debt may contain limitations on our ability to pay cash upon conversion or repurchase of the Convertible
Notes.

Holders of the Convertible Notes have the right to require us to repurchase all or a portion of their Convertible Notes upon the occurrence of a
fundamental change at a price equal to the principal amount of the Convertible Notes to be repurchased, plus accrued and unpaid interest. In addition, upon
conversion of the Convertible Notes, unless we elect to deliver solely shares of our common stock to settle such conversion (other than paying cash in lieu
of delivering any fractional share), we will be required to make cash payments in respect of the Convertible Notes being converted. However, we may not
have enough available cash or be able to obtain financing at the time we are required to make repurchases of Convertible Notes surrendered therefor or
Convertible Notes being converted. In addition, our ability to repurchase the Convertible Notes or to pay cash upon conversions of the Convertible Notes
may be limited by law, by regulatory authority or by agreements governing our future indebtedness. Our failure to repurchase Convertible Notes at a time
when the repurchase is required by the indenture or to pay any cash payable on future conversions of the Convertible Notes as required by the indenture
would constitute a default under the indenture. A default under the indenture or the fundamental

44

 
 
 
 
 
 
 
change itself could also lead to a default under agreements governing our existing or future indebtedness. If the repayment of the related indebtedness were
to be accelerated after any applicable notice or grace periods, we may not have sufficient funds to repay the indebtedness and repurchase the Convertible
Notes or make cash payments upon conversions thereof.

The conditional conversion feature of the Convertible Notes, if triggered, may adversely affect our financial condition and operating results.

In the event the conditional conversion feature of the Convertible Notes is triggered, holders of Convertible Notes will be entitled to convert the
Convertible Notes at any time during specified periods at their option. If one or more holders elect to convert their Convertible Notes, unless we elect to
satisfy our conversion obligation by delivering solely shares of our common stock (other than paying cash in lieu of delivering any fractional share), we
would be required to settle a portion or all of our conversion obligation in cash, which could adversely affect our liquidity. In addition, even if holders do
not elect to convert their Convertible Notes, we could be required under applicable accounting rules to reclassify all or a portion of the outstanding
principal amount of the Convertible Notes as a current rather than long-term liability, which would result in a material reduction of our net working capital.

The accounting method for convertible debt securities could have a material effect on our reported financial results.

In May 2008, the Financial Accounting Standards Board, or FASB, issued FASB Staff Position No. APB 14-1, Accounting for Convertible Debt

Instruments That May Be Settled in Cash Upon Conversion (Including Partial Cash Settlement), which has subsequently been codified as Accounting
Standards Codification 470-20, Debt with Conversion and Other Options, or ASC 470-20. Under ASC 470-20, an entity must separately account for the
liability and equity components of the convertible debt instruments (such as the Convertible Notes) that may be settled entirely or partially in cash upon
conversion in a manner that reflects the issuer’s economic interest cost. The effect of ASC 470-20 on the accounting for the Convertible Notes is that the
equity component is required to be included in the additional paid-in capital section of stockholders’ equity on our consolidated balance sheet, and the
value of the equity component would be treated as original issue discount for purposes of accounting for the debt component of the Convertible Notes. As a
result, we will be required to record a greater amount of non-cash interest expense in current periods presented as a result of the amortization of the
discounted carrying value of the Convertible Notes to their face amount over the term of the Convertible Notes. We will report lower net income in our
financial results because ASC 470-20 will require interest to include both the current period’s amortization of the debt discount and the instrument’s
coupon interest, which could adversely affect our reported or future financial results, the trading price of our common stock and the trading price of the
Convertible Notes.

In addition, under certain circumstances, convertible debt instruments (such as the Convertible Notes) that may be settled entirely or partly in cash
are currently accounted for utilizing the treasury stock method, the effect of which is that the shares issuable upon conversion of the Convertible Notes are
not included in the calculation of diluted earnings per share except to the extent that the conversion value of the Convertible Notes exceeds their principal
amount. Under the treasury stock method, for diluted earnings per share purposes, the transaction is accounted for as if the number of shares of common
stock that would be necessary to settle such excess, if we elected to settle such excess in shares, are issued. We cannot be sure that the accounting standards
in the future will continue to permit the use of the treasury stock method. If we are unable to use the treasury stock method in accounting for the shares
issuable upon conversion of the Convertible Notes, then our diluted earnings per share would be adversely affected.

In August 2020, the FASB issued ASU 2020-06, Debt – Debt with Conversion and Other Options (Subtopic 470-20) to reduce complexity in
applying GAAP to certain financial instruments with characteristics of liability and equity.  The Company early adopted this statement effective January 1,
2021.  The impact of the adoption of the statement is to increase debt and decrease equity by the amount of the equity component of convertible notes
recognized in equity and to decrease the interest expense by the non-cash portion of the discount amortization.  Adoption of this statement or other changes
to the current accounting standards related to the Convertible Notes could decrease our weighted average basic earnings per share or other financial
metrics, but we do not believe that the adoption of this statement will have a materially adverse impact upon our financial statements.

Risks Related to the Discovery, Development and Commercialization of Our Product Candidates

There are no approved therapies that act by inhibiting C3, and we may not be able to successfully develop and commercialize pegcetacoplan or other
product candidates.

Pegcetacoplan is a novel therapeutic compound and its potential benefit in controlling complement-dependent autoimmune and inflammatory

diseases has not been established. Pegcetacoplan is designed to control disease through inhibition of C3. There are no approved therapies for our target
indications that act by inhibiting C3 and only two approved therapies that act by inhibiting the complement system. As a result, pegcetacoplan may not
demonstrate in patients any or all of the pharmacological benefits we believe it may possess. We have not yet obtained marketing approval of any product
candidate. We have evaluated pegcetacoplan in preclinical studies and in clinical trials and have advanced pegcetacoplan into Phase 3 clinical development
in geographic atrophy, or GA, and PNH.  We have submitted an NDA to the FDA and a MAA to the EMA for pegcetacoplan for the treatment of PNH in

45

September 2020, but we have not obtained regulatory approval to sell pegcetacoplan, APL-9 or any product based on our therapeutic approaches.

If we are unsuccessful in our development efforts, we may not be able to advance the development of pegcetacoplan or any other product candidate,

commercialize products, raise capital, expand our business or continue our operations.

The COVID-19 pandemic may affect our ability to initiate and complete preclinical studies and conduct our ongoing clinical trials, delay the initiation
of  planned  and  future  clinical  trials,  disrupt  regulatory  activities,  or  have  other  adverse  effects  on  our  business  and  operations.  In  addition,  this
pandemic may adversely impact economies worldwide, which could result in adverse effects on our business and operations and ability to raise capital.

The COVID-19 pandemic has caused many governments to implement measures to slow the spread of the outbreak through quarantines, strict travel

restrictions, heightened border scrutiny, and other measures. The outbreak and government measures taken in response have had a significant impact, both
direct and indirect, on businesses and commerce, as worker shortages have occurred; supply chains have been disrupted; facilities and production have
been suspended; and demand for certain goods and services, such as medical services and supplies, has spiked, while demand for other goods and services,
such as travel, has fallen. The future progression of the pandemic and its effects on our business and operations are uncertain.

A small number of employees of our company, including our chief executive officer, have indicated that they were diagnosed with COVID-19.

These employees, including our chief executive officer, have subsequently recovered. We have re-opened our facilities on a limited basis with strict
guidelines, but most of our employees continue to work remotely.

We have enrolled, and seek to enroll, patients in our ongoing clinical trials at sites located both in the United States and internationally. We may face

difficulties recruiting and retaining patients in our ongoing clinical trials because of logistical effects arising from the pandemic, including increased
difficulty for patients and health care providers to travel to or access clinical sites. If patients enrolled in our clinical trials are unable or unwilling to visit
clinical trial sites, the data generated by the trials and the timing of completion of our clinical trials may be adversely affected particularly in clinical trials
like DERBY and OAKS where patients are expected to travel to clinical sites on a monthly basis over an extended period of time. We may also face
disruptions related to the ability to obtain necessary regulatory, institutional review board, or IRB, or other necessary site approvals, as well as other delays
at clinical trial sites. In particular, site initiation, participant recruitment and enrollment, participant dosing, availability of drug product or clinical and
laboratory supplies, distribution of clinical trial materials, study monitoring, and data analysis may be paused or delayed due to changes in hospital or
university policies, federal, state or local regulations, prioritization of hospital resources toward pandemic efforts, or other reasons related to the pandemic.
The potential suspension of clinical trial activity at clinical trial sites may have an adverse impact on our clinical trial plans and timelines.

Treatment with complement inhibitors, like pegcetacoplan and APL-9, has immunosuppressive effects. Elderly patients or patients with significantly

compromised health, such as those in our clinical trials, could be more susceptible to infections and other complications as a result of treatment with
complement inhibitors. The COVID-19 pandemic could lead to delayed enrollment in our trials, more frequent missed visits from ongoing trials and more
frequent or severe adverse events during our trials.

We also may face disruptions as a result of the COVID-19 pandemic that affect our ability to procure items that are essential for our research and

development activities, including, for example, raw materials used in the manufacturing of our product candidates and laboratory and clinical supplies for
our clinical trials. If we experience supply issues, our clinical trial plans and business operations could be adversely affected.  

The response to the COVID-19 pandemic may redirect resources with respect to regulatory and intellectual property matters in a way that would

adversely impact our ability to progress regulatory approvals and protect our intellectual property. In addition, we may face impediments to regulatory
meetings and in obtaining regulatory approvals due to measures intended to limit in-person interactions which could adversely impact the ability of
regulatory authorities to take all steps needed to grant regulatory approval and could cause regulatory authorities to defer action on our regulatory
submissions, including limitations or delays of inspections of facilities by regulatory authorities, which may impact approval timelines.

Any negative impact that the COVID-19 pandemic has on recruiting or retaining patients in our clinical trials or on the ability of our suppliers to

provide materials for our product candidates could cause additional delays to clinical trial activities, which could materially and adversely affect our ability
to obtain regulatory approval for and to commercialize our product candidates, increase our operating expenses, affect our ability to raise additional capital,
and have a material adverse effect on our financial results.

The COVID-19 pandemic has significantly impacted economies worldwide, which could result in adverse effects on our business, operations and

ability to raise capital. We cannot be certain what the overall impact of the continuation or worsening of the COVID-19 pandemic may be on our business.
It has the potential to adversely affect our business, financial condition, results of operations, and prospects.

46

We are dependent on the successful development and commercialization of our lead product candidate, pegcetacoplan. If we are unable to develop,
obtain marketing approval for or successfully commercialize pegcetacoplan, either alone or through a collaboration, or if we experience significant
delays in doing so, our business could be harmed.

We currently have no products approved for sale and are investing a significant portion of our efforts and financial resources to fund the

development of pegcetacoplan. We submitted an NDA to the FDA and a MAA to the EMA for pegcetacoplan for the treatment of PNH in September 2020.
The FDA accepted the NDA and set the PDUFA target action date for May 14, 2021.  The EMA validated the MAA in October 2020, with the potential for
a European Commission decision on the MAA in the second half of 2021. Pursuant to our agreement with Sobi, we have granted to Sobi the exclusive right
to commercialize systemic pegcetacoplan outside the United States. Our prospects are substantially dependent on our ability, or that of Sobi or any future
collaborator, to develop, obtain marketing approval for and successfully commercialize pegcetacoplan in one or more disease indications. All of our other
product candidates are in early stages of clinical development.

The success of pegcetacoplan will depend on several factors, including the following:

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

successful recruitment of patients, enrollment in and completion of our ongoing and planned clinical trials;

initiation and successful recruitment of patients, enrollment in and completion of additional clinical trials;

safety, tolerability and efficacy profiles that are satisfactory to the FDA, EMA or any comparable foreign regulatory authority for marketing
approval;

our ability to identify success criteria and endpoints for our clinical trials and otherwise design our clinical trials such that the FDA, EMA,
and other regulatory authorities will be able to determine the clinical efficacy and safety profile of any product candidates we may develop;

timely receipt of marketing approvals from applicable regulatory authorities;

the extent of any required post-marketing approval commitments to applicable regulatory authorities;

establishment of supply arrangements with third-party suppliers and manufacturers of raw materials and drug intermediates;

establishment of arrangements with third-party manufacturers to obtain finished products that are appropriately packaged for sale;

obtaining pegcetacoplan drug product from third-party manufacturers of sufficient quality to be used in our clinical trials and for commercial
sale;

developing, validating and maintaining a commercially viable manufacturing process that is compliant with current good manufacturing
practices, or cGMPs;

the performance of Sobi and any future collaborators;

obtaining and maintaining patent, trade secret protection and regulatory exclusivity, both in the United States and internationally;

protection of our rights in our intellectual property portfolio;

successful launch of commercial sales following any marketing approval;

an acceptable safety profile following any marketing approval;

commercial acceptance of our products, if approved, by patients, the medical community and third-party payors;

our ability to compete with other therapies; and

obtaining and maintaining healthcare coverage and adequate reimbursement.

Many of these factors are beyond our control, including clinical development, the regulatory submission process, potential threats to our intellectual

property rights and the manufacturing, marketing and sales efforts of our collaborators, including Sobi. If we are unable to develop, receive marketing
approval for and successfully commercialize pegcetacoplan on our own or with a collaborator, or experience delays as a result of any of these factors or
otherwise, our business could be substantially harmed.

47

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
If clinical trials of our product candidates fail to satisfactorily demonstrate safety and efficacy to the FDA and other regulators, we, may incur
additional costs or experience delays in completing, or ultimately be unable to complete, the development and commercialization of these product
candidates.

We are not permitted to commercialize, market, promote or sell any product candidate in the United States without obtaining marketing approval

from the FDA. Foreign regulatory authorities, such as the EMA, impose similar requirements. Prior to September 2020, we had not previously submitted or
similar drug approval filings to comparable foreign regulatory authorities for any of our product candidates. In September 2020, we submitted an NDA to
the FDA and a MAA to the EMA for pegcetacoplan for the treatment of PNH.  We may never receive such approvals. We must complete extensive
preclinical development and clinical trials to demonstrate the safety and efficacy of our product candidates in humans before we will be able to obtain these
approvals.

Clinical testing is expensive, is difficult to design and implement, can take many years to complete and is inherently uncertain as to outcome. We

cannot guarantee that any clinical trials will be conducted as planned or completed on schedule, if at all. The clinical development of our product
candidates is susceptible to the risk of failure inherent at any stage of product development, including failure to demonstrate efficacy in a clinical trial or
across a broad population of patients, the occurrence of adverse events that are severe or medically or commercially unacceptable, failure to comply with
protocols or applicable regulatory requirements and determination by the FDA or any comparable foreign regulatory authority that a product candidate may
not continue development or is not approvable. It is possible that even if one or more of our product candidates has a beneficial effect, that effect will not
be detected during clinical evaluation as a result of one or more of a variety of factors, including the size, duration, design, measurements, conduct or
analysis of our clinical trials. Conversely, as a result of the same factors, our clinical trials may indicate an apparent positive effect of a product candidate
that is greater than the actual positive effect, if any. Similarly, in our clinical trials we may fail to detect toxicity or intolerability caused by our product
candidates, or mistakenly believe that our product candidates are toxic or not well tolerated when that is not in fact the case. Many companies in the
pharmaceutical and biotechnology industries have suffered significant setbacks in late-stage clinical trials after achieving positive results in earlier
development, and we cannot be certain that we will not face additional setbacks. It is possible that any of our development programs may be placed on full
or partial clinical hold by regulatory authorities at any point, which would delay and possibly prevent further development of our product candidates.

In October 2018, we announced that we voluntarily implemented a pause in dosing in our Phase 3 clinical program in patients with GA due to
observed cases of non-infectious inflammation in patients treated from a single manufacturing lot of pegcetacoplan ophthalmological drug product. We also
voluntarily implemented a pause in our Phase 1b/2 trial of pegcetacoplan in patients with wet AMD, which we subsequently discontinued. A total of eight
patients, four in the Phase 3 GA program and four in our Phase 1b/2 clinical trial of pegcetacoplan in patients with wet AMD, were treated with
pegcetacoplan from this manufacturing lot and each patient developed non-infectious inflammation. Inflammation in all eight patients completely resolved.
We modified our manufacturing process in order to eliminate an impurity in the active pharmaceutical ingredient and have manufactured sufficient supply
of pegcetacoplan utilizing the modified manufacturing process to conduct the Phase 3 GA program. In March 2019, we restarted enrollment of our Phase 3
clinical program in GA, and we announced that we completed enrollment in July 2020. 

Any inability to successfully complete preclinical and clinical development could result in additional costs to us and impair our ability to generate

revenues from product sales, regulatory and commercialization milestones and royalties. Moreover, if we are required to conduct additional clinical trials or
other testing of our product candidates beyond the trials and testing that we contemplate, if we are unable to successfully complete clinical trials of our
product candidates or other testing or the results of these trials or tests are unfavorable, uncertain or are only modestly favorable, or there are unacceptable
safety concerns associated with our product candidates, we may:

•

•

•

•

•

•

•

incur additional unplanned costs;

be delayed in obtaining marketing approval for our product candidates;

not obtain marketing approval at all;

obtain approval for indications or patient populations that are not as broad as intended or desired;

obtain approval with labeling that includes significant use or distribution restrictions or significant safety warnings, including boxed
warnings;

be subject to additional post-marketing testing or other requirements; or

be required to remove the product from the market after obtaining marketing approval.

Under our collaboration with Sobi, we are relying on Sobi to conduct certain clinical trials of pegcetacoplan and seek regulatory approval for
pegcetacoplan outside the United States.  If Sobi or any future collaborator are unable to successfully complete clinical trials of our product candidates and
obtain regulatory approvals on a timely basis, or at all, our ability to generate revenues from product sales, regulatory and commercialization milestones
and royalties may be materially impaired.

48

 
 
 
 
 
 
 
In addition, investigators for our clinical trials and other service providers may serve as scientific advisors or consultants to us from time to time and

receive compensation in connection with such services, including equity awards and option grants, and may have other financial interests in our company.
We are required to collect and provide financial disclosure notifications or certifications for our clinical investigators to the FDA. If the FDA concludes that
a financial relationship between us and a clinical investigator has created a conflict of interest or otherwise affected interpretation of the trial, the FDA may
question the integrity of the data generated at the applicable clinical trial site and the utility of the clinical trial itself may be jeopardized. This could result
in a delay in approval, or rejection, of our marketing applications by the FDA and may ultimately lead to the denial of marketing approval of our current
and future product candidates.

Our failure to successfully complete clinical trials of our product candidates and to demonstrate the efficacy and safety necessary to obtain

regulatory approval to market any of our product candidates would significantly harm our business.

Adverse events or undesirable side effects caused by, or other unexpected properties of, any of our product candidates may be identified during
development that could delay or prevent their marketing approval or limit their use.

Adverse events or undesirable side effects caused by, or other unexpected properties of, our product candidates could cause us, or any collaborator

conducting clinical trials of our product candidates such as Sobi, an institutional review board or regulatory authorities to interrupt, delay or halt clinical
trials of one or more of our product candidates and could result in a more restrictive label, or the delay or denial of marketing approval by the FDA or
comparable foreign regulatory authorities. For example, by design pegcetacoplan has immunosuppressive effects and, in some cases, may be administered
to patients with underlying significantly compromised health. Administration of our product candidates could make patients more susceptible to infection.

In addition, in preclinical studies of pegcetacoplan, we observed evidence of minimal to mild kidney toxicity when animals were administered

relatively higher doses of pegcetacoplan than the doses we intend to use in the treatment of patients. We believe this kidney toxicity is likely associated
with the presence of polyethylene glycol, or PEG, which is a component of pegcetacoplan. If such kidney toxicity, or other adverse effects, were to arise in
patients being treated with pegcetacoplan or any other of our product candidates, it could require us to halt, delay or interrupt clinical trials of such product
candidate or adversely affect our ability to obtain requisite approvals to advance the development and commercialization of such product candidate.

In our Phase 2 trial of pegcetacoplan in patients with GA, the most frequently reported adverse events were associated with the injection procedure

in the study eye. These adverse events included two cases of confirmed endophthalmitis, which is inflammation in the eye typically caused by infection,
and one case of presumed endophthalmitis where the culture tested negative for bacterial growth. In addition, during the 12-month treatment period and the
subsequent six-month period during which no treatment was administered, we observed a higher incidence of new onset exudation, or fluid leakage in the
retinas of eyes in which exudation had not previously been reported, in the study eyes treated with pegcetacoplan, predominantly in patients with a history
of wet AMD in the non-study eye, or fellow eye. Specifically, we observed that, after the 12-month treatment period and the six-month monitoring period,
21% of patients who received administration of pegcetacoplan every month and 9% of patients who received administration of pegcetacoplan every other
month showed new onset exudation in the study eye as compared to 1% of the sham group. As we continue development of pegcetacoplan for GA, if a
significant number of patients develop new onset exudation, then we may need to limit development of ophthalmological pegcetacoplan to certain uses or
subpopulations in which the undesirable side effects or other characteristics are less prevalent, less severe or more acceptable from a risk-benefit
perspective.

In our Phase 3 clinical trial of pegcetacoplan in patients with GA and our Phase 1b/2 clinical trial of pegcetacoplan in patients with wet AMD,
several patients treated from a single manufacturing lot of pegcetacoplan ophthalmological drug product experienced non-infectious inflammation. A total
of eight patients, four in our Phase 3 GA program and four in our Phase 1b/2 clinical trial of pegcetacoplan in patients with wet AMD, were treated with
this pegcetacoplan from this manufacturing lot and each patient developed non-infectious inflammation. Inflammation in these patients has completely
resolved.

In our Phase 3 PEGASUS trial, the safety profile observed in the pegcetacoplan was comparable to the safety profile observed in the eculizumab
arm and consistent with previously reported data.   After the 48-week study period, twenty-four of 80 pegcetacoplan monotherapy-treated patients (30%)
experienced a serious adverse event (SAE).  Five of the SAEs (6%) were assessed to be possibly related to study treatment. No cases of meningitis were
reported. One death was reported due to COVID-19 and was unrelated to study treatment. The most common adverse events (AEs) reported throughout the
study were injection site reactions (36%), hemolysis (24%), and diarrhea (21%). Twelve out of 80 patients (15%) discontinued due to adverse events, with
five discontinuations due to hemolysis. Sixty-four of the 67 patients (96%) who completed the open-label period opted to enter the extension study.

If any of our product candidates is associated with adverse events or undesirable side effects or has properties that are unexpected, we, or our

collaborators, may abandon development or limit development of that product candidate to certain uses or subpopulations in which the undesirable side
effects or other characteristics are less prevalent, less severe or more acceptable from a

49

risk-benefit perspective. Many compounds that initially showed promise in clinical or earlier stage testing have later been found to cause undesirable or
unexpected side effects that prevented further development of the compound.

In addition, clinical trials by their nature utilize a sample of the potential patient population. However, with a limited number of subjects and limited

duration of exposure, rare and severe side effects of our product candidates may only be uncovered when a significantly larger number of patients are
exposed to the product. If safety problems occur or are identified after one of our products reaches the market, the FDA or comparable non-U.S. regulatory
authorities may require that we amend the labeling of our product, recall our product, or even withdraw approval for our product.

If we, or any collaborator conducting clinical trials of any of our product candidates such as Sobi, experience any of a number of possible unforeseen
events in connection with clinical trials of our product candidates, potential clinical development, marketing approval or commercialization of our
product candidates could be delayed or prevented.

We, or our collaborators, may experience numerous unforeseen events during, or as a result of, clinical trials that could delay or prevent clinical

development, marketing approval or commercialization of our product candidates, including:

•

•

•

•

•

•

•

•

•

•

•

•

•

•

clinical trials of our product candidates may produce unfavorable or inconclusive results;

we, or our collaborators, may decide, or regulators may require us or them, to conduct additional clinical trials or abandon product
development programs;

the number of patients required for clinical trials of our product candidates may be larger than we, or our collaborators, anticipate, patient
enrollment in these clinical trials may be slower than we, or our collaborators, anticipate or participants may drop out of these clinical trials at
a higher rate than we, or our collaborators, anticipate;

the cost of planned clinical trials of our product candidates may be greater than we anticipate;

our third-party contractors or those of our collaborators, including those manufacturing our product candidates or components or ingredients
thereof or conducting clinical trials on our behalf or on behalf of our collaborators, may deviate from the trial protocol, fail to comply with
regulatory requirements or fail to meet their contractual obligations to us or our collaborators in a timely manner or at all;

regulators or institutional review boards may not authorize us, our collaborators or our or their investigators to commence a clinical trial or
conduct a clinical trial at a prospective trial site;

we, or our collaborators, may have delays in reaching or fail to reach agreement on acceptable clinical trial contracts or clinical trial protocols
with prospective trial sites;

patients that enroll in a clinical trial may misrepresent their eligibility to do so or may otherwise not comply with the clinical trial protocol,
resulting in the need to drop the patients from the clinical trial, increase the needed enrollment size for the clinical trial or extend the clinical
trial’s duration;

we, or our collaborators, may have to delay, suspend or terminate clinical trials of our product candidates for various reasons, including a
finding that the participants are being exposed to unacceptable health risks, undesirable side effects or other unexpected characteristics of the
product candidate;

regulators or institutional review boards may require that we, or our collaborators, or our or their investigators suspend or terminate clinical
research for various reasons, including noncompliance with regulatory requirements or their standards of conduct, a finding that the
participants are being exposed to unacceptable health risks, undesirable side effects or other unexpected characteristics of the product
candidate or findings of undesirable effects caused by a chemically or mechanistically similar product or product candidate;

the FDA or comparable foreign regulatory authorities may disagree with our, or our collaborators’, clinical trial designs or our or their
interpretation of data from preclinical studies and clinical trials, including the data from our PEGASUS trial;

the FDA or comparable foreign regulatory authorities may fail to approve or subsequently find fault with the manufacturing processes or
facilities of third-party manufacturers with which we, or our collaborators, enter into agreements for clinical and commercial supplies;

the supply or quality of raw materials, drug intermediates or manufactured product candidates, other products evaluated in our clinical trials
or other materials necessary to conduct clinical trials of our product candidates may be insufficient, inadequate or not available at an
acceptable cost, or we may experience interruptions in supply; and

the approval policies or regulations of the FDA or comparable foreign regulatory authorities may significantly change in a manner rendering
our clinical data insufficient to obtain marketing approval.

50

 
 
 
 
 
 
 
 
 
 
 
 
 
 
Should the COVID-19 pandemic persist, our clinical development plans could be affected, and we may be unable to conduct our clinical trials in the

manner or on the timelines that we currently anticipate. Clinical trial participants and clinical investigators may not be able to comply with clinical trial
protocols, if for example quarantines or other travel limitations impede participant movement, affect sponsor access to study sites, or interrupt healthcare
services. The COVID-19 pandemic could lead to delayed enrollment in our trials, more frequent missed appointments and withdrawals from ongoing trials
and more frequent or severe adverse events during our trials.  

Product development costs for us will increase if we experience delays in testing or pursuing marketing approvals and we may be required to obtain
additional funds to complete clinical trials and prepare for possible commercialization of our product candidates. We do not know whether any preclinical
tests or clinical trials will begin as planned, will need to be restructured, or will be completed on schedule or at all. Significant preclinical study or clinical
trial delays also could shorten any periods during which we, or our collaborators, may have the exclusive right to commercialize our product candidates or
allow our competitors, or the competitors of our collaborators, to bring products to market before we, or our collaborators, do and impair our ability, or the
ability of our collaborators, to successfully commercialize our product candidates and may harm our business and results of operations. In addition, many
of the factors that lead to clinical trial delays may ultimately lead to the denial of marketing approval of any of our product candidates.

If we, or any collaborator conducting clinical trials of any of our product candidates such as Sobi, experience delays or difficulties in the enrollment of
patients in clinical trials, our or their receipt of necessary regulatory approvals could be delayed or prevented.

We, or our collaborators, may not be able to initiate or continue clinical trials for any of our product candidates if we, or they, are unable to locate

and enroll a sufficient number of eligible patients to participate in clinical trials as required by the FDA or comparable foreign regulatory authorities.
Patient enrollment is a significant factor in the timing of clinical trials, and is affected by many factors, including:

•

•

•

•

•

•

•

•

•

the size and nature of the patient population;

the severity of the disease under investigation;

the proximity of patients to clinical sites;

the patient referral practices of physicians;

the eligibility criteria for the trial;

the design of the clinical trial;

efforts to facilitate timely enrollment;

competing clinical trials; and

clinicians’ and patients’ perceptions as to the potential advantages and risks of the drug being studied in relation to other available therapies,
including any new drugs that may be approved for the indications we are investigating.

Many of the indications for which we are developing product candidates are rare diseases with small patient populations, and many of those patients

are treated with other therapies or products. Further, there are only a limited number of specialist physicians that regularly treat patients with these rare
diseases and major clinical centers that support such treatment are concentrated in a few geographic regions. In addition, other companies are conducting
clinical trials and have announced plans for future clinical trials that are seeking, or are likely to seek, to enroll patients with these rare diseases and patients
are generally only able to enroll in a single trial at a time. Both patients and their physicians may be reluctant to forgo, discontinue or otherwise alter
existing, approved life-saving therapeutic approaches. Given the severe and life-threatening nature of these indications and the expectation that many
patients will be on treatment with other therapies or products, we may encounter difficulty in recruiting a sufficient number of patients for our trials
including in particular our planned clinical trials. The small population of patients, competition for these patients, the nature of the disease and limited trial
sites may make it difficult for us to enroll enough patients to complete our clinical trials of pegcetacoplan in a timely and cost-effective manner. These
difficulties may be exacerbated as a result of the ongoing COVID-19 pandemic.

Our inability, or the inability of our collaborators, to enroll a sufficient number of patients for our, or their, clinical trials could result in significant
delays or may require us or them to abandon one or more clinical trials altogether. Enrollment delays in our, or their, clinical trials may result in increased
development costs for our product candidates, delay or halt the development of and approval processes for our product candidates and jeopardize our, or
our collaborators’, ability to commence sales of and generate revenues from our product candidates, which could cause the value of our company to decline
and limit our ability to obtain additional financing, if needed.

51

 
 
 
 
 
 
 
 
 
Results of preclinical studies and Phase 1 and Phase 2 clinical trials may not be predictive of results of later clinical trials.

The outcome of preclinical studies and Phase 1 and Phase 2 clinical trials may not be predictive of the success of later clinical trials, and preliminary

or interim results of clinical trials do not necessarily predict final results. Many companies in the pharmaceutical and biotechnology industries have
suffered significant setbacks in late-stage clinical trials after achieving positive results in earlier stages of clinical development, and we could face similar
setbacks. Similarly, the design of a clinical trial can determine whether its results will support approval of a product and flaws in the design of a clinical
trial may not become apparent until the clinical trial is well advanced.

In addition, preclinical and clinical data are often susceptible to varying interpretations and analyses. Many companies that believed their product

candidates performed satisfactorily in preclinical studies and clinical trials have nonetheless failed to obtain marketing approval for the product candidates.
Even if we, or our collaborators, believe that the results of clinical trials for our product candidates warrant marketing approval, the FDA or comparable
foreign regulatory authorities may disagree and may not grant marketing approval of our product candidates.

Some of the data we present on the use of pegcetacoplan for the treatment of GA is drawn from post hoc analyses of data subsets from our Phase 2

clinical trial. While we believe these data were useful in informing the design of future Phase 3 clinical trials for pegcetacoplan, post hoc analyses
performed after unmasking trial results can result in the introduction of bias and may not be predictive of success in Phase 3 clinical trials.

In some instances, there can be significant variability in safety or efficacy results between different clinical trials of the same product candidate due
to numerous factors, including changes in trial procedures set forth in protocols, differences in the size and type of the patient populations, changes in and
adherence to the dosing regimen and other clinical trial protocols and the rate of dropout among clinical trial participants. For instance, the Phase 3 clinical
trials in GA are similar in design to the Phase 2 clinical trial, except that patients will be treated with pegcetacoplan for 24 months rather than 12 months
and there will not be a six-month monitoring period following treatment. Additionally, unlike the Phase 2 clinical trial, GA lesion size will be measured by
total area rather than mean change in the square root of GA lesion size. In our Phase 3 clinical trials in GA, statistical significance is set at a p-value of 0.05
or less, meaning that there is a 1-in-20 or less probability that the observed results occurred by chance rather than as a treatment effect. In our Phase 2
clinical trial, we set statistical significance as a p-value of 0.1 or less, meaning that there is a 1-in-10 or less probability that the observed results occurred
by chance. If we fail to receive positive results in clinical trials of our product candidates, the development timeline and regulatory approval and
commercialization prospects for our most advanced product candidates, and, correspondingly, our business and financial prospects would be negatively
impacted.

If we fail to develop and commercialize other product candidates, we may be unable to grow our business.

Although the development and commercialization of pegcetacoplan is our primary focus, as part of our growth strategy, we are developing a
pipeline of product candidates for the treatment of complement-dependent diseases. These other product candidates will require additional, time-consuming
and costly development efforts prior to commercial sale, including preclinical studies, clinical trials and approval by the FDA and/or applicable foreign
regulatory authorities. All product candidates are prone to the risks of failure that are inherent in pharmaceutical product development, including the
possibility that the product candidate will not be shown to be sufficiently safe and effective for approval by regulatory authorities. In addition, there can be
no assurance that any such products that are approved will be manufactured or produced economically, successfully commercialized or widely accepted in
the marketplace or be more effective than other commercially available alternatives.

We may not be successful in our efforts to develop APL-9 for the treatment of patients with respiratory failure including acute respiratory distress
syndrome secondary to COVID-19.

In May 2020, we initiated a Phase 1/2 clinical trial of APL-9 as a potential treatment for patients with respiratory failure including acute respiratory

distress syndrome, or ARDS, secondary to COVID-19. ARDS is a serious lung condition that causes low blood oxygen, often resulting in hospitalization
and mechanical ventilation or other life-support measures.

The timing and success of our clinical trial of APL-9 for the treatment of these COVID-19 patients will depend on our ability to enroll patients in

the trial. Many other companies are pursuing the development of product candidates for the treatment of COVID-19, and patient enrollment may be
affected by availability of commercially available treatments and other clinical trials of competing product candidates. Patient enrollment may also be
affected by other factors, including the incidence of COVID-19 over time and the perceived risks and benefits of the use of APL-9 as a treatment relative to
competing treatments. Our inability to enroll a sufficient number of patients could result in significant delays or could require us to abandon the trial and
development of APL-9 for the treatment of these patients altogether.

The COVID-19 pandemic may be effectively contained before we can successfully develop APL-9 as a treatment for these COVID-19 patients and

we may not be able to recoup our financial investment in the trial through sales of APL-9. For example, since

52

December 2020, the FDA has issued the first emergency use authorizations for COVID-19 vaccines developed by Pfizer and BioNTech and
Moderna.  Additional vaccines may be approved in 2021. The vaccines are being distributed and may be available in sufficient quantities to contain the
spread of the SARS-CoV-2 virus before we are able to obtain marketing approval of APL-9 for the treatment of COVID-19. Our commitment of financial
resources and personnel to the development of APL-9 for the treatment of these patients may cause delays in or otherwise negatively impact our other
development programs and research and discovery efforts with our other product candidates. Various government entities and private foundations are
offering incentives, grants and contracts to encourage additional investment into treatments for patients with COVID-19. Such funding may have the effect
of increasing the number of competitors and/or providing advantages to competitors working on treatments for COVID-19.

In this trial, we are administering APL-9 as an add-on to the current standard of care. The standard of care for COVID-19 patients may change

during our trial or following our trial, and the clinical data that we obtain in our ongoing Phase 1/2 may not translate to supporting the use of APL-9 as an
add-on to a new standard of care. To date, patients with ARDS secondary to COVID-19 have experienced high fatality rates and the response of these
patients with treatment may differ from the treatment of patients with typical ARDS that is not secondary to COVID-19. Given the severe nature of the
indication and limited treatment history of patients with ARDS secondary to COVID-19, we cannot be certain that APL-9 will be able to demonstrate a
clinical benefit as a treatment option for these patients.

Given the rapidity of the onset of the COVID-19 pandemic, scientific and medical research on the SARS-CoV-2 virus is ongoing and evolving. We

cannot be certain that the evidence that we believe suggests that APL-9 may be beneficial to these patients will be established in a clinical trial.
Furthermore, the failure of APL-9 to demonstrate safety and efficacy in these patients could negatively impact the perception of us and APL-9 by investors.
Additionally, it is possible that unexpected safety issues could occur in these COVID-19 patients. Any such safety issues could affect our development
plans for APL-9 in other indications.

We have never obtained marketing approval for a product candidate and we may be unable to obtain, or may be delayed in obtaining, marketing
approval for any of our product candidates.

We have never obtained marketing approval for a product candidate. We submitted an NDA to the FDA and a MAA to the EMA for pegcetacoplan

for the treatment of PNH in September 2020. The FDA may not approve our NDA and the EMA may not approve or EMA for pegcetacoplan for the
treatment of PNH. Although the FDA set the PDUFA target action date and the EMA validated the MAA in Europe, it is possible that the FDA or EMA
may refuse to accept for substantive review any NDAs or MAAs that we submit for our product candidates.  In addition, the FDA and EMA or may
conclude after review of our data that our application is insufficient to obtain marketing approval of pegcetacoplan. If the FDA or EMA does not accept or
approve our NDA or MAA for pegcetacoplan, it may require that we conduct additional clinical trials, preclinical studies or manufacturing validation
studies and submit that data before it will reconsider our applications. Depending on the extent of these or any other required trials or studies, approval of
any NDA, MAA or application that we submit may be delayed by several years or may require us to expend more resources than we have available. It is
also possible that additional trials or studies, if performed and completed, may not be considered sufficient by the FDA or EMA to approve our NDAs or
MAAs.

The FDA has advised us that, for the approval of a new treatment for PNH, hemoglobin stabilization in conjunction with change in transfusion

dependence constitute accepted clinical benefit, but that a rise in hemoglobin levels may not translate to clinical benefit in patients who entered the trial
with high hemoglobin levels, such as permitted by the inclusion criteria of the PEGASUS trial, and who do not require transfusions. We believe that the
data from the PEGASUS trial support a finding of clinical benefit. We submitted an NDA to the FDA and an MAA to the EMA for pegcetacoplan for the
treatment of PNH in September 2020.

Any delay in obtaining, or an inability to obtain, marketing approvals would prevent us from commercializing pegcetacoplan in the United States or

EU, generating revenues and achieving and sustaining profitability. If any of these outcomes occur, either to pegcetacoplan or to any future product
candidate for which we may seek marketing approval, we may be forced to abandon our development efforts for pegcetacoplan or such future product
candidates, which could significantly harm our business.

Even if pegcetacoplan or one of our other product candidates that we develop receives marketing approval, we or others may later discover that the
product is less effective than previously believed or causes undesirable side effects that were not previously identified, which could compromise our
ability, or that of our collaborators, to market the product.

Clinical trials of our product candidates are conducted in carefully defined sets of patients who have agreed to enter into clinical trials.
Consequently, it is possible that our clinical trials, or those of our collaborators, may indicate an apparent positive effect of a product candidate that is
greater than the actual positive effect, if any, or alternatively fail to identify undesirable side effects. If, following approval of a product candidate, we, or
others, discover that the product is less effective than previously believed or causes undesirable side effects that were not previously identified, any of the
following adverse events could occur:

•

regulatory authorities may withdraw their approval of the product or seize the product;

53

 
•

•

•

•

•

•

•

•

we, or our collaborators, may be required to recall the product, change the way the product is administered or conduct additional clinical
trials;

additional restrictions may be imposed on the marketing of, or the manufacturing processes for, the particular product;

we may be subject to fines, injunctions or the imposition of civil or criminal penalties;

regulatory authorities may require the addition of labeling statements, such as a “black box” warning or a contraindication;

we, or our collaborators, may be required to create a Medication Guide outlining the risks of the previously unidentified side effects for
distribution to patients;

we, or our collaborators, could be sued and held liable for harm caused to patients;

the product may become less competitive; and

our reputation may suffer.

Any of these events could harm our business and operations and could negatively impact our stock price.

Even if pegcetacoplan or one of our other product candidates that we develop receives marketing approval, it may fail to achieve the degree of market
acceptance by physicians, patients, third-party payors and others in the medical community necessary for commercial success, in which case we may
not generate significant revenues or become profitable.

We have never commercialized a product, and even if pegcetacoplan or one of our other product candidates that we develop is approved by the

appropriate regulatory authorities for marketing and sale, it may nonetheless fail to gain sufficient market acceptance by physicians, patients, third-party
payors and others in the medical community. Physicians are often reluctant to switch their patients from existing therapies even when new and potentially
more effective or convenient treatments enter the market. Further, patients often acclimate to the therapy that they are currently taking and do not want to
switch unless their physicians recommend switching products or they are required to switch therapies due to lack of reimbursement for existing therapies.
Eculizumab (marketed as Soliris) and ravulizumab (marketed as Ultomiris) are the only therapies that have been approved for the treatment of PNH, and
even if we are able to obtain marketing approval of pegcetacoplan for the treatment of PNH, we may not be able to successfully convince physicians or
patients to switch from eculizumab or ravulizumab to pegcetacoplan. This may be particularly true with respect to eculizumab as many in the medical
community believe that patients with PNH on eculizumab may experience sudden and excessive blood cell lysis, or rupture, leading to anemia, blood clots
and other medical problems, when they stop receiving eculizumab. In addition, even if we are able to demonstrate our product candidates’ safety and
efficacy to the FDA and other regulators, safety concerns in the medical community may hinder market acceptance.

Efforts to educate the medical community and third-party payors on the benefits of our product candidates may require significant resources and

may not be successful. If pegcetacoplan or any of our other product candidates that we develop is approved but does not achieve an adequate level of
market acceptance, we may not generate significant revenues and we may not become profitable. The degree of market acceptance of pegcetacoplan or our
other product candidates that we develop, if approved for commercial sale, will depend on a number of factors, including:

•

•

•

•

•

•

•

•

•

•

•

•

•

the efficacy and safety of the product;

the potential advantages of the product compared to competitive therapies;

the prevalence and severity of any side effects;

the clinical indications for which the product is approved;

whether the product is designated under physician treatment guidelines as a first-, second- or third-line therapy;

the price at which the product is offered for sale;

the product’s convenience and ease of administration compared to alternative treatments;

the willingness of the target patient population to try, and of physicians to prescribe, the product;

limitations or warnings, including distribution or use restrictions contained in the product’s approved labeling;

the strength of sales, marketing and distribution support;

the approval of other new products for the same indications;

the timing of market introduction of our approved products as well as competitive products;

adverse publicity about the product or favorable publicity about competitive products;

54

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
•

•

•

potential product liability claims;

changes in the standard of care for the targeted indications for the product; and

availability and amount of coverage and reimbursement from government payors, managed care plans and other third-party payors.

In addition, the potential market opportunity for pegcetacoplan in any indication is difficult to precisely estimate. Our estimates of the potential
market opportunity for pegcetacoplan include several key assumptions based on our industry knowledge, industry publications, third-party research reports
and other surveys. However, no independent source has verified such assumptions. If any of these assumptions proves to be inaccurate, then the actual
market for pegcetacoplan could be smaller than our estimates of potential market opportunity. If the actual market for pegcetacoplan is smaller than we
expect, our product revenue may be limited, and it may be more difficult for us to achieve or maintain profitability.

We may expend our limited resources to pursue a particular product candidate or indication and fail to capitalize on product candidates or indications
that may be more profitable or for which there is a greater likelihood of success.

Because we have limited financial and managerial resources, we intend to focus on developing product candidates for specific indications that we

identify as most likely to succeed, in terms of both their potential for marketing approval and commercialization. As a result, we may forego or delay
pursuit of opportunities with other product candidates or for other indications that may prove to have greater commercial potential.

Our resource allocation decisions may cause us to fail to capitalize on viable commercial products or profitable market opportunities. Our spending

on current and future research and development programs and product candidates for specific indications may not yield any commercially viable product
candidates. If we do not accurately evaluate the commercial potential or target market for a particular product candidate, we may relinquish valuable rights
to that product candidate through collaboration, licensing or other royalty arrangements in cases in which it would have been more advantageous for us to
retain sole development and commercialization rights to the product candidate.

If we are unable to establish sales, marketing and distribution capabilities or enter into sales, marketing and distribution arrangements with third
parties, we may not be successful in commercializing any product candidates if approved.

We are currently developing sales, marketing and distribution infrastructure in the United States to support commercialization of systemic
pegcetacoplan for the treatment of PNH and worldwide infrastructure for our other product candidates, including pegcetacoplan as a treatment for GA.

We are building focused capabilities to commercialize development programs for certain indications where we believe that the medical specialists

for the indications such as PNH are sufficiently concentrated to allow us to effectively promote the product with a targeted sales team. The development of
sales, marketing and distribution capabilities requires substantial resources, is time-consuming and could delay any product launch. If the commercial
launch of a product candidate for which we recruit a sales force and establish marketing and distribution capabilities is delayed or does not occur for any
reason, we could have prematurely or unnecessarily incurred these commercialization costs. This may be costly, and our investment could be lost if we
cannot retain or reposition our sales and marketing personnel. In addition, we may not be able to hire or retain a sales force in the United States that is
sufficient in size or has adequate expertise in the medical markets that we plan to target. If we are unable to establish or retain a sales force and marketing
and distribution capabilities, our operating results may be adversely affected. If a potential partner has development or commercialization expertise that we
believe is particularly relevant to one of our products, then we may seek to collaborate with that potential partner even if we believe we could otherwise
develop and commercialize the product independently.

In certain indications, we may seek to enter into collaborations that we believe may contribute to our ability to advance development and ultimately

commercialize our product candidates. We may also seek to enter into collaborations where we believe that realizing the full commercial value of our
development programs will require access to broader geographic markets or the pursuit of broader patient populations or indications. As a result of entering
into arrangements with third parties to perform sales, marketing and distribution services, our product revenues or the profitability of these product
revenues may be lower, perhaps substantially lower, than if we were to directly market and sell products in those markets. Furthermore, we may be
unsuccessful in entering into the necessary arrangements with third parties or may be unable to do so on terms that are favorable to us. In addition, we may
have little or no control over such third parties, and any of them may fail to devote the necessary resources and attention to sell and market our products
effectively.

If we do not establish sales, marketing and distribution capabilities, either on our own or in collaboration with third parties, we will not be successful

in commercializing any of our product candidates that receive marketing approval.

We have granted exclusive commercialization rights for systemic pegcetacoplan outside of the United States to Sobi under our agreement with

Sobi.  If Sobi is unable to meet its contractual obligations, we may be forced to focus our efforts internally to

55

 
 
 
 
commercialize systemic pegcetacoplan outside of the United States without the assistance of a commercialization partner or seek another
commercialization partner, either of which would result in us incurring greater expenses and could cause a delay in market penetration while we expand our
commercial operations or seek an alternative commercialization partner. Such costs may exceed the increased revenues we would receive from direct
systemic pegcetacoplan sales outside of the United States, at least in the near term. We would also be forced to declare a breach of the agreement with Sobi
and seek a termination of the agreement which could result in an extended and uncertain dispute with Sobi, including arbitration or litigation, any of which
would be costly.

We face substantial competition, which may result in others discovering, developing or commercializing products before or more successfully than
we do.

The development and commercialization of new products is highly competitive, as described in “Competition,” above. We expect that we, and our
collaborators, will face significant competition from major pharmaceutical companies, specialty pharmaceutical companies and biotechnology companies
worldwide with respect to any of our product candidates that we, or our collaborators, may seek to develop or commercialize in the future, including from
therapies that act through the complement system and therapies that use different approaches.

Our competitors may succeed in developing, acquiring or licensing technologies and products that are more effective, have fewer side effects or

more tolerable side effects or are less costly than any product candidates that we are currently developing or that we may develop, which could render our
product candidates obsolete and noncompetitive.

Our commercial opportunity could be reduced or eliminated if our competitors develop and commercialize products that are safer, more effective,

have fewer or less severe side effects, are more convenient or are less expensive than any products that we, or our collaborators, may develop. Our
competitors also may obtain FDA or other marketing approval for their products before we, or our collaborators, are able to obtain approval for ours, which
could result in our competitors establishing a strong market position before we, or our collaborators, are able to enter the market.

Many of our existing and potential future competitors have significantly greater financial resources and expertise in research and development,
manufacturing, preclinical testing, conducting clinical trials, obtaining marketing approvals and marketing approved products than we do. Mergers and
acquisitions in the pharmaceutical and biotechnology industries may result in even more resources being concentrated among a smaller number of our
competitors. Smaller or early-stage companies may also prove to be significant competitors, particularly through collaborative arrangements with large and
established companies. These competitors also compete with us in recruiting and retaining qualified scientific and management personnel and establishing
clinical trial sites and patient registration for clinical trials, as well as in acquiring technologies complementary to, or necessary for, the development of our
product candidates.

If the FDA or comparable foreign regulatory authorities approve generic versions of any of our products that receive marketing approval, or such
authorities do not grant our products appropriate periods of data exclusivity before approving generic versions of our products, the sales of our
products could be adversely affected.

Once an NDA is approved, the product covered thereby becomes a “reference-listed drug” in the FDA’s publication, “Approved Drug Products with

Therapeutic Equivalence Evaluations,” or the Orange Book. Manufacturers may seek approval of generic versions of reference-listed drugs through
submission of an ANDA in the United States. In support of an ANDA, a generic manufacturer need not conduct clinical trials. Rather, the applicant
generally must show that its product has the same active ingredient(s), dosage form, strength, route of administration and conditions of use or labeling as
the reference-listed drug and that the generic version is bioequivalent to the reference-listed drug, meaning it is absorbed in the body at the same rate and to
the same extent. Generic products may be significantly less costly to bring to market than the reference-listed drug and companies that produce generic
products are generally able to offer them at lower prices. Thus, following the introduction of a generic drug, a significant percentage of the sales of any
branded product or reference-listed drug may be typically lost to the generic product.

The FDA may not approve an ANDA for a generic product until any applicable period of non-patent exclusivity for the reference-listed drug has
expired. The Federal Food, Drug, and Cosmetic Act, or FDCA, provides a period of five years of non-patent exclusivity for a new drug containing a new
chemical entity, or NCE. Specifically, in cases where such exclusivity has been granted, an ANDA may not be filed with the FDA until the expiration of
five years unless the submission is accompanied by a Paragraph IV certification that a patent covering the reference-listed drug is either invalid or will not
be infringed by the generic product, in which case the applicant may submit its application four years following approval of the reference-listed drug. It is
unclear whether the FDA will treat the active ingredients in our product candidates as NCEs and, therefore, afford them five years of NCE data exclusivity
if they are approved. If any product we develop does not receive five years of NCE exclusivity, the FDA may approve generic versions of such product
three years after its date of approval, subject to the requirement that the ANDA applicant certifies to any patents listed for our products in the Orange Book.
Manufacturers may seek to launch these generic products following the expiration of the applicable marketing exclusivity period, even if we still have
patent protection for our product.

56

Competition that our products may face from generic versions of our products could negatively impact our future revenue, profitability and cash

flows and substantially limit our ability to obtain a return on our investments in those product candidates.

Even if we, or any collaborator that is commercializing any of our product candidates such as Sobi, are able to commercialize any product candidate,
the product may become subject to unfavorable pricing regulations, third-party payor reimbursement practices or healthcare reform initiatives, any of
which could harm our business.

The commercial success of our product candidates will depend substantially, both domestically and abroad, on the extent to which the costs of our

product candidates will be paid by third-party payors, including government health administration authorities and private health coverage insurers. If
coverage and reimbursement is not available, or reimbursement is available only to limited levels, we, or our collaborators, may not be able to successfully
commercialize our product candidates. Even if coverage is provided, the approved reimbursement amount may not be high enough to allow us, or our
collaborators, to establish or maintain pricing sufficient to realize a sufficient return on our or their investments. In the United States, no uniform policy of
coverage and reimbursement for products exists among third-party payors and coverage and reimbursement for products can differ significantly from payor
to payor. As a result, the coverage determination process is often a time-consuming and costly process that will require us to provide scientific and clinical
support for the use of our products to each payor separately, with no assurance that coverage and adequate reimbursement will be applied consistently or
obtained in the first instance.

There is significant uncertainty related to third-party payor coverage and reimbursement of newly approved drugs. Marketing approvals, pricing and

reimbursement for new drug products vary widely from country to country. Some countries require approval of the sale price of a drug before it can be
marketed. In many countries, the pricing review period begins after marketing or product licensing approval is granted. In some foreign markets,
prescription pharmaceutical pricing remains subject to continuing governmental control even after initial approval is granted. As a result, we, or our
collaborators, might obtain marketing approval for a product in a particular country, but then be subject to price regulations that delay commercial launch
of the product, possibly for lengthy time periods, which may negatively impact the revenues we are able to generate from the sale of the product in that
country. Adverse pricing limitations may hinder our ability or the ability of our collaborators to recoup our or their investment in one or more product
candidates, even if our product candidates obtain marketing approval.

Patients who are provided medical treatment for their conditions generally rely on third-party payors to reimburse all or part of the costs associated
with their treatment. Therefore, our ability, and the ability of our collaborators, to commercialize any of our product candidates will depend in part on the
extent to which coverage and reimbursement for these products and related treatments will be available from third-party payors. Third-party payors decide
which medications they will cover and establish reimbursement levels. The healthcare industry is acutely focused on cost containment, both in the United
States and abroad. Government authorities and other third-party payors have attempted to control costs by limiting coverage and the amount of
reimbursement for particular medications, which could affect our ability or that of our collaborators to sell our product candidates profitably. These payors
may not view our products, if any, as cost-effective, and coverage and reimbursement may not be available to our customers, or those of our collaborators,
or may not be sufficient to allow our products, if any, to be marketed on a competitive basis. Cost-control initiatives could cause us, or our collaborators, to
decrease the price we, or they, might establish for products, which could result in lower than anticipated product revenues. If the prices for our products, if
any, decrease or if governmental and other third-party payors do not provide coverage or adequate reimbursement, our prospects for revenue and
profitability will suffer.

The commercial potential of our products depends in part on reimbursement by government health administration authorities, private health insurers

and other organizations. If we, or any collaborator that is commercializing our product candidates such as Sobi are unable to obtain coverage or
reimbursement for our products, as monotherapy or in combination with other therapies, including possible combinations with eculizumab or ravulizumab,
at the levels anticipated, our financial condition could be harmed. Additionally, if new compounds currently in development by potential competitors,
including biosimilars of eculizumab or ravulizumab, obtain marketing approval, there may be downward pressure on reimbursement levels for therapies in
our target disease areas, which could have a negative impact on our ability to achieve and maintain profitability.

There may also be delays in obtaining coverage and reimbursement for newly approved drugs, and coverage may be more limited than the

indications for which the drug is approved by the FDA or comparable foreign regulatory authorities. Moreover, eligibility for reimbursement does not
imply that any drug will be paid for in all cases or at a rate that covers our costs, including research, development, manufacture, sale and distribution.
Reimbursement rates may vary, by way of example, according to the use of the product and the clinical setting in which it is used. Reimbursement rates
may also be based on reimbursement levels already set for lower cost drugs or may be incorporated into existing payments for other services.

In addition, increasingly, third-party payors are requiring higher levels of evidence of the benefits and clinical outcomes of new technologies and are

challenging the prices charged. We cannot be sure that coverage will be available for any product candidate that we, or any collaborator, including Sobi,
commercialize and, if available, that the reimbursement rates will be adequate. Further, the net reimbursement for drug products may be subject to
additional reductions if there are changes to laws that presently restrict imports of drugs from countries where they may be sold at lower prices than in the
United States. An inability to promptly obtain coverage and

57

adequate payment rates from both government-funded and private payors for any of our product candidates for which we, or our collaborator, obtain
marketing approval could significantly harm our operating results, our ability to raise capital needed to commercialize products and our overall financial
condition.

Product liability lawsuits against us could divert our resources, cause us to incur substantial liabilities and limit commercialization of any products that
we may develop.

We face an inherent risk of product liability claims as a result of the clinical testing of our product candidates despite obtaining appropriate informed

consents from our clinical trial participants. We will face an even greater risk if we or our collaborators including Sobi, commercially sell any product that
we may develop. For example, we may be sued if any product we develop allegedly causes injury or is found to be otherwise unsuitable during clinical
testing, manufacturing, marketing or sale. Any such product liability claims may include allegations of defects in manufacturing, defects in design, a failure
to warn of dangers inherent in the product, negligence, strict liability or a breach of warranties. Claims could also be asserted under state consumer
protection acts. If we cannot successfully defend ourselves against product liability claims, we may incur substantial liabilities or be required to limit
commercialization of our product candidates. Regardless of the merits or eventual outcome, liability claims may result in:

•

•

•

•

•

•

•

•

decreased demand for our product candidates or products that we may develop;

injury to our reputation and significant negative media attention;

withdrawal of clinical trial participants;

significant costs to defend resulting litigation;

substantial monetary awards to trial participants or patients;

loss of revenue;

reduced resources of our management to pursue our business strategy; and

the inability to commercialize any products that we may develop.

Although we maintain product liability insurance coverage in the amount of up to $20.0 million in the aggregate and clinical trial liability insurance

of up to $20.0 million in the aggregate, this insurance may not fully cover potential liabilities that we may incur. The cost of any litigation or other
proceeding, even if resolved in our favor, could be substantial. We will need to increase our insurance coverage if we commercialize any product that
receives marketing approval. In addition, insurance coverage is becoming increasingly expensive. If we are unable to maintain sufficient insurance
coverage at an acceptable cost or to otherwise protect against potential product liability claims, it could prevent or inhibit the development and commercial
production and sale of our product candidates, which could harm our business, financial condition, results of operations and prospects.

Our internal information systems, or those of any contractors, consultants, vendors, business partners or other third parties, may fail or suffer security
breaches, which could result in a material disruption of our product development programs.

We collect, store and transmit large amounts of confidential information, including personal information and information relating to intellectual
property, on internal information systems and through the information systems of our contractors, consultants, vendors, business partners or other third
parties.  

Despite the implementation of security measures, our internal information systems and those of third parties are vulnerable to damage from

computer viruses, malware, unauthorized access, natural disasters, terrorism, war and telecommunication and electrical failures. Such systems are also
vulnerable to service interruptions or to security breaches from inadvertent or intentional actions by our employees, our collaborators, contractors,
consultants, vendors, business partners and other third parties, or from cyber-attacks by malicious third parties over the Internet or through other
mechanisms. Cyber-attacks are increasing in their frequency, sophistication and intensity, and have become increasingly difficult to detect. Cyber-attacks
could include the deployment of harmful malware, ransomware, denial of service attacks, social engineering and other means to affect service reliability
and threaten the confidentiality, integrity and availability of information. Cyber-attacks also could include phishing attempts or e-mail fraud to cause
payments or information to be transmitted to an unintended recipient.

While we have not experienced any such material system failure, accident, cyber-attack or security breach to date, if such an event were to occur and

cause interruptions in our operations, it could result in a material disruption of our development programs, clinical trials and business operations, whether
due to a loss of our trade secrets or other proprietary information or other similar disruptions, in addition to possibly requiring substantial expenditures of
resources to remedy. For example, the loss of clinical trial data from clinical trials could result in delays or termination of our regulatory approval efforts
and significantly increase our costs to recover or reproduce the data. In addition, as risks with respect to our information systems continue to evolve, we
will incur additional

58

 
 
 
 
 
 
 
 
costs to maintain the security of our information systems and comply with evolving laws and regulations pertaining to cybersecurity and related areas. To
the extent that any disruption or security breach were to result in a loss of, or damage to, our data or applications, or inappropriate disclosure of confidential
or proprietary information, we could incur liability, including regulatory fines and other losses with respect to privacy claims, enrollment in our clinical
trials could be negatively affected, our competitive position and reputation could be harmed and the further development and commercialization of our
product candidates could be delayed.

Risks Related to Our Dependence on Third Parties

We rely on third parties to conduct our clinical trials. If they do not perform satisfactorily, our business could be harmed.

We do not independently conduct clinical trials of our product candidates. We rely, and expect to continue to rely, on third parties, such as contract

research organizations, clinical data management organizations, medical institutions and clinical investigators, to conduct our clinical trials of
pegcetacoplan and any other product candidate that we develop. Any of these third parties may terminate their engagements with us under certain
circumstances. We may not be able to enter into alternative arrangements or do so on commercially reasonable terms. In addition, there is a natural
transition period when a new contract research organization begins work. As a result, delays would likely occur, which could negatively impact our ability
to meet our expected clinical development timelines and harm our business, financial condition and prospects.

Further, although our reliance on these third parties for clinical development activities limits our control over these activities, we remain responsible

for ensuring that each of our trials is conducted in accordance with the applicable protocol, legal, regulatory and scientific standards. For example,
notwithstanding the obligations of a contract research organization for a trial of one of our product candidates, we remain responsible for ensuring that each
of our clinical trials is conducted in accordance with the general investigational plan and protocols for the trial. Moreover, the FDA requires us to comply
with standards, commonly referred to as current Good Clinical Practices, or cGCPs, for conducting, recording and reporting the results of clinical trials to
assure that data and reported results are credible and accurate and that the rights, integrity and confidentiality of trial participants are protected. The FDA
enforces these cGCPs through periodic inspections of trial sponsors, principal investigators, clinical trial sites and institutional review boards. If we or our
third-party contractors fail to comply with applicable cGCPs, the clinical data generated in our clinical trials may be deemed unreliable and the FDA may
require us to perform additional clinical trials before approving our product candidates, which would delay the marketing approval process. We cannot be
certain that, upon inspection, the FDA will determine that any of our clinical trials comply with cGCPs. Similar regulatory requirements apply outside the
United States, including the International Council for Harmonisation of Technical Requirements for the Registration of Pharmaceuticals for Human Use, or
ICH. We are also required to register clinical trials and post the results of completed clinical trials on a government-sponsored database, ClinicalTrials.gov,
within certain timeframes. Failure to do so can result in fines, adverse publicity and civil and criminal sanctions.

Furthermore, the third parties conducting clinical trials on our behalf are not our employees, and except for remedies available to us under our
agreements with such contractors, we cannot control whether or not they devote sufficient time, skill and resources to our ongoing development programs.
These contractors may also have relationships with other commercial entities, including our competitors, for whom they may also be conducting clinical
trials or other drug development activities, which could impede their ability to devote appropriate time to our clinical programs. In addition, these
contractors may be adversely affected by the COVID-19 pandemic. If these third parties do not successfully carry out their contractual duties, meet
expected deadlines or conduct our clinical trials in accordance with regulatory requirements or our stated protocols, we may not be able to obtain, or may
be delayed in obtaining, marketing approvals for our product candidates. If that occurs, we will not be able to, or may be delayed in our efforts to,
successfully commercialize our product candidates. In such an event, our financial results and the commercial prospects for any product candidates that we
seek to develop could be harmed, our costs could increase and our ability to generate revenues could be delayed, impaired or foreclosed.

We contract with third parties for the manufacture, storage and distribution of our product candidates for clinical trials and expect to continue to do so
in connection with our future development and commercialization efforts. This reliance on third parties increases the risk that we will not have
sufficient quantities of pegcetacoplan or our other product candidates or such quantities at an acceptable cost, which could delay, prevent or impair our
development or commercialization efforts.

We currently have no manufacturing facilities, and a relatively small number of personnel with manufacturing experience who can oversee the
manufacturing process. We rely on contract manufacturers to manufacture, store and distribute both drug substance and drug product required for our
clinical trials. We plan to continue to rely upon contract manufacturers, and, potentially collaboration partners, to manufacture commercial quantities of our
products, if approved. We may be unable to establish any

59

agreements with contract manufacturers or to do so on acceptable terms, or to maintain such agreements as we may enter. Even if we are able to establish
agreements with contract manufacturers, reliance on contract manufacturers entails additional risks, including:

•

•

•

•

•

•

•

manufacturing delays if our third-party contractors give greater priority to the supply of other products over our product candidates or
otherwise do not satisfactorily perform according to the terms of the agreements between us and them, or if unforeseen events in the
manufacturing process arise;

the possible termination or nonrenewal of agreements by our third-party contractors at a time that is costly or inconvenient for us;

the possible breach by the third-party contractors of our agreements with them;

the failure of third-party contractors to comply with applicable regulatory requirements;

the possible mislabeling of clinical supplies, potentially resulting in the wrong dose amounts being supplied or active drug or placebo not
being properly identified;

the possibility of clinical supplies not being delivered to clinical sites on time, leading to clinical trial interruptions, or of drug supplies not
being distributed to commercial vendors in a timely manner, resulting in lost sales; and

the possible misappropriation of our proprietary information, including our trade secrets and know-how.

We currently rely, and expect to continue to rely, on a small number of third-party contract manufacturers to supply most of our supply of active
pharmaceutical ingredients and required finished product for our preclinical studies and clinical trials.  In particular, we have entered into a commercial
supply agreement with Bachem Americas, Inc., or Bachem, to purchase a significant portion of our requirements for the pegcetacoplan drug substance over
the next five years.  We have also entered into long-term commercial supply agreements with other suppliers of raw materials, drug substance and drug
product. If any of our existing manufacturers should become unavailable to us for any reason, we may incur delays in identifying or qualifying
replacements. We also rely on other third parties to store and distribute drug supplies for our clinical trials. Any performance failure on the part of our
contract manufacturers or distributors could delay clinical development or marketing approval of our product candidates or commercialization of any
resulting products, producing additional losses and depriving us of potential product revenue. For example, in the past we experienced issues associated
with the manufacturing process for pegcetacoplan that resulted in delays in the supply of pegcetacoplan. These delays resulted in us incurring additional
costs and delays in our PNH development program. Additionally, in October 2018, we announced that we voluntarily implemented a pause in dosing in our
clinical trials in patients with GA and wet AMD due to observed cases of non-infectious inflammation in patients treated from a single manufacturing lot of
pegcetacoplan ophthalmological drug product that we believe occurred due to an impurity in the active pharmaceutical ingredient. If we experience other
issues or delays in the future, our development of pegcetacoplan may be materially delayed and our business adversely affected.

Any manufacturing problem, the loss of a contract manufacturer or any loss of storage could be disruptive to our operations, delay our clinical trials

and, if our products are approved for sale, result in lost sales. Additionally, we rely on third parties to supply the raw materials needed to manufacture our
product candidates. For example, one company currently produces most of the PEG that is used in pharmaceutical and drug development globally. PEG is a
component of pegcetacoplan. If this supplier of PEG experiences manufacturing and supply problems with respect to PEG, then the manufacturers with
whom we contract may have difficulty in procuring PEG for the supply and manufacture of pegcetacoplan. Any reliance on suppliers may involve several
risks, including a potential inability to obtain critical materials and reduced control over production costs, delivery schedules, reliability and quality. If we
or any third-party parties on which we rely are adversely impacted by restrictions or limitations resulting from the COVID-19 pandemic, our ability to
manufacture and supply pegcetacoplan may be disrupted, which would limit our ability to conduct our clinical trials or prepare for our commercial launch.
Any unanticipated disruption to our contract manufacturing caused by problems at suppliers could delay shipment of our product candidates, increase our
cost of goods sold and result in lost sales with respect to any approved products.

If any of our product candidates are approved by any regulatory agency, we will need to enter into agreements with third-party contract

manufacturers for the commercial production and distribution of those products. It may be difficult for us to reach agreement with a contract manufacturer
on satisfactory terms or in a timely manner. In addition, we may face competition for access to manufacturing facilities as there are a limited number of
contract manufacturers operating under cGMPs that can manufacture our product candidates. Consequently, we may not be able to reach agreement with
third-party manufacturers on satisfactory terms, which could delay our commercialization efforts.

60

 
 
 
 
 
 
 
Third-party manufacturers are required to comply with cGMPs and similar regulatory requirements outside the United States, such as the ICH.

Facilities used by our third-party manufacturers must be approved by the FDA after we submit an NDA and before potential approval of the product
candidate. Similar regulations apply to manufacturers of our product candidates for use or sale in foreign countries. We do not control the manufacturing
process and are completely dependent on our third-party manufacturers for compliance with the applicable regulatory requirements for the manufacture of
our product candidates. If our manufacturers cannot successfully manufacture material that conforms to our specifications or the strict regulatory
requirements of the FDA and any applicable foreign regulatory authority, they may not be able to meet our supply requirements for clinical and commercial
operations and to secure the applicable approval for their manufacturing facilities. If these facilities are not approved for commercial manufacture, we may
need to find alternative manufacturing facilities, which could result in delays in obtaining approval for the applicable product candidate.

In addition, our manufacturers are subject to ongoing periodic inspections by the FDA and corresponding state and foreign agencies for compliance
with cGMPs and similar regulatory requirements both prior to and following the receipt of marketing approval for any of our product candidates. Some of
these inspections may be unannounced. Failure by any of our manufacturers to comply with applicable cGMPs or other regulatory requirements could
result in sanctions being imposed on us, including fines, injunctions, civil penalties, delays, suspensions or withdrawals of approvals, operating restrictions,
interruptions in supply and criminal prosecutions, any of which could significantly impact the available supplies of our product candidates and harm our
business, financial condition and results of operations.

We are developing a custom, on-body drug delivery system that would enable patients to self-administer pegcetacoplan through subcutaneous
infusion. While this device is in development, we plan to use one or more commercially available ambulatory infusion pumps in our ongoing and planned
clinical trials and for our commercial launch of pegcetacoplan as a treatment for PNH. The development of a custom drug delivery system may be delayed,
or we may not be successful in developing a custom drug delivery system and may need to continue to rely on commercially available ambulatory infusion
pumps. Any reliance on third-party infusion pumps may involve several risks, including reduced control over costs, delivery schedules, reliability and
quality.

Our current and anticipated future dependence upon others for the manufacture of our product candidates may harm our future profit margins and

our ability to commercialize any products that receive marketing approval on a timely and competitive basis.

Our prospects for the development and commercialization of our product candidates will depend in significant part on the success of our collaboration
with Sobi and future collaborations.

We have entered into a collaboration with Sobi for the global co-development and commercialization outside of the United States of systemic
pegcetacoplan and we may seek to enter into additional collaborations for the development and commercialization of certain of our product candidates. We
may have limited control over the amount and timing of resources that our collaborators, including Sobi, will dedicate to the development or
commercialization of our product candidates. Our ability to generate revenues from these arrangements will depend on our collaborators’ abilities to
successfully perform the functions assigned to them in these arrangements. In addition, our collaborators may have the right to abandon research or
development projects and terminate applicable agreements, including funding obligations, prior to or upon the expiration of the agreed upon terms.

Collaborations involving our product candidates pose a number of risks, including the following:

•

•

•

•

•

•

•

collaborators have significant discretion in determining the efforts and resources that they will apply to these collaborations;

collaborators may not perform their obligations as expected;

collaborators may not pursue development and commercialization of our product candidates or may elect not to continue or renew
development or commercialization programs, based on clinical trial results, changes in the collaborators’ strategic focus or available funding
or external factors, such as an acquisition, that divert resources or create competing priorities;

collaborators may delay clinical trials, provide insufficient funding for a clinical trial program, stop a clinical trial or abandon a product candidate,
repeat or conduct new clinical trials or require a new formulation of a product candidate for clinical testing;

collaborators could independently develop, or develop with third parties, products that compete directly or indirectly with our product
candidates;

a collaborator with marketing and distribution rights to one or more products may not commit sufficient resources to the marketing and
distribution of such product or products;

disagreements with collaborators, including disagreements over proprietary rights, contract interpretation or the preferred course of
development, might cause delays or termination of the research, development or commercialization of product

61

 
 
 
 
 
 
 
candidates, might lead to additional responsibilities for us with respect to product candidates, or might result in litigation or arbitration, any of
which would be time-consuming and expensive;

collaborators may not properly maintain or defend our intellectual property rights or may use our proprietary information in such a way as to
invite litigation that could jeopardize or invalidate our intellectual property or proprietary information or expose us to potential litigation;

collaborators may infringe the intellectual property rights of third parties, which may expose us to litigation and potential liability;

disputes may arise between the collaborators and us regarding ownership of or other rights in the intellectual property generated in the course
of the collaborations; and

collaborations may be terminated and, if terminated, may result in a need for additional capital to pursue further development or
commercialization of the applicable product candidates.

•

•

For example, our agreement with Sobi is subject to early termination in the event of any uncured material breach of the agreement or under specific

circumstances relating to insolvency. If we do not maintain a productive collaborative relationship with Sobi or if Sobi is unable to meet its contractual
obligations or if there is an early termination of the agreement as described above, we would be forced to either establish a commercial infrastructure
outside of the United States so that we could undertake the commercialization efforts which had been theretofore undertaken by Sobi or we would need to
seek an alternative collaborator. The establishment of a commercial infrastructure and assumption by us of commercialization activities outside of the
United States would require substantial resources, financial and otherwise, and could result in us incurring greater expenses than the increase in revenues
from our direct sales of systemic pegcetacoplan. It could also cause a delay in market penetration while we expand our commercial operations. Seeking and
obtaining an alternative collaborator outside the United States could also adversely impact sales of systemic pegcetacoplan and market penetration outside
of the United States.

Collaboration agreements may not lead to development or commercialization of product candidates in the most efficient manner or at all. If our

collaborators, including Sobi are involved in a business combination, it could decide to delay, diminish or terminate the development or commercialization
of any product candidate licensed to it by us.

We have in the past established, and in the future, may seek to establish, additional collaborations and, if we are not able to establish them on
commercially reasonable terms, we may have to alter our development and commercialization plans.

We entered into the collaboration agreement with Sobi in October 2020 concerning the development and commercialization of pegcetacoplan and
specified other structurally and functionally similar compstatin analogues or derivatives for use systemically or for local non-ophthalmic administration.
We may seek to establish one or more additional collaborators for the development and commercialization of one or more of our product candidates. Likely
collaborators may include large and mid-size pharmaceutical companies, regional and national pharmaceutical companies and biotechnology companies. In
addition, if we are able to obtain marketing approval for product candidates from foreign regulatory authorities, we intend to enter into strategic
relationships with international biotechnology or pharmaceutical companies for the commercialization of such product candidates outside of the United
States.

We face significant competition in seeking appropriate collaborators. Whether we reach a definitive agreement for a collaboration will depend,
among other things, upon our assessment of the collaborator’s resources and expertise, the terms and conditions of the proposed collaboration and the
proposed collaborator’s evaluation of a number of factors. Those factors may include the potential differentiation of our product candidates from competing
product candidates, design or results of clinical trials, the likelihood of approval by the FDA or comparable foreign regulatory authorities and the regulatory
pathway for any such approval, the potential market for the product candidate, the costs and complexities of manufacturing and delivering the product to
patients and the potential of competing products. The collaborator may also consider alternative product candidates or technologies for similar indications
that may be available for collaboration and whether such a collaboration could be more attractive than the one with us for our product candidate. If we elect
to increase our expenditures to fund development or commercialization activities on our own, we may need to obtain additional capital, which may not be
available to us on acceptable terms or at all. If we do not have sufficient funds, we may not be able to further develop our product candidates or bring them
to market and generate product revenue.

Collaborations are complex and time-consuming to negotiate and document. Further, there have been a significant number of recent business
combinations among large pharmaceutical companies that have resulted in a reduced number of potential future collaborators.

Any collaboration agreements that we enter into in the future may contain restrictions on our ability to enter into potential collaborations or to

otherwise develop specified product candidates. Our collaboration agreement with Sobi, we agreed not to, directly or indirectly, alone or with or for any
other person or entity, conduct any clinical development or commercialization of APL-9 for

62

 
 
 
 
 
PNH, cold agglutinin disease, hematopoietic stem cell transplantation thrombotic microangiopathy, C3 glomerulopathy and immune complex
membranoproliferative glomerulonephritis, and amyotrophic lateral sclerosis or any other indications subsequently agreed upon by the parties.

We may not be able to negotiate collaborations on a timely basis, on acceptable terms, or at all. If we are unable to do so, we may have to curtail the

development of the product candidate for which we are seeking to collaborate, reduce or delay its development program or one or more of our other
development programs, delay its potential commercialization or reduce the scope of any sales or marketing activities, or increase our expenditures and
undertake development or commercialization activities at our own expense.

Risks Related to Our Intellectual Property

If we fail to comply with our obligations under our existing and any future intellectual property licenses with third parties, we could lose license rights
that are important to our business.

We are a party to patent license agreements with The University of Pennsylvania under which we license patent rights relating to a family of
compounds for use in all fields. The licensed patent rights include issued U.S. and foreign patents with claims that recite a class of compounds generically
covering our lead product candidates, pegcetacoplan and APL-9, and that specifically recite the active component. We may enter into additional license
agreements in the future. Our license agreements with Penn impose, and we expect that future license agreements will impose, various diligence, milestone
payment, royalty, insurance and other obligations on us. If we fail to comply with our obligations under these licenses, our licensors may have the right to
terminate these license agreements, in which event we might not be able to market any product that is covered by these agreements, or our licensors may
convert the license to a non-exclusive license, which could negatively impact the value of the product candidate being developed under the license
agreement. Termination of these license agreements or reduction or elimination of our licensed rights may also result in our having to negotiate new or
reinstated licenses with less favorable terms.

If we are unable to obtain and maintain sufficient patent protection for our product candidates, or if the scope of the patent protection is not
sufficiently broad, our competitors could develop and commercialize products similar or identical to ours, and our ability to successfully commercialize
our product candidates may be adversely affected.

Our success depends in large part on our ability to obtain and maintain patent protection in the United States and other countries with respect to our
proprietary product candidates. If we do not adequately protect our intellectual property rights, competitors may be able to erode or negate any competitive
advantage we may have, which could harm our business and ability to achieve profitability. To protect our proprietary position, we file patent applications
in the United States and abroad related to our novel product candidates that are important to our business; we also license or purchase patent applications
filed by others. The patent application and approval process is expensive and time-consuming. We may not be able to file and prosecute all necessary or
desirable patent applications at a reasonable cost or in a timely manner.

Agreements through which we license patent rights may not give us control over patent prosecution or maintenance, so that we may not be able to
control which claims or arguments are presented and may not be able to secure, maintain, or successfully enforce necessary or desirable patent protection
from those patent rights. We have not had and do not have primary control over patent prosecution and maintenance for certain of the patents and patent
applications we license, and therefore cannot guarantee that these patents and applications will be prosecuted in a manner consistent with the best interests
of our business. We cannot be certain that patent prosecution and maintenance activities by our licensors have been or will be conducted in compliance
with applicable laws and regulations or will result in valid and enforceable patents.

We, or any partners, collaborators, or licensees, may fail to identify patentable aspects of inventions made in the course of development and

commercialization activities before it is too late to obtain patent protection on them. Therefore, we may miss potential opportunities to strengthen our
patent position. Moreover, in some circumstances, we might not have the right to control the preparation, filing and prosecution of patent applications, or to
maintain the patents, covering any technology that we may license from third parties in the future. These patents and applications may not be prosecuted
and enforced in a manner consistent with the best interests of our business. Our license agreements with Penn provide that Penn has the right under certain
circumstances to control the preparation, prosecution and maintenance of the underlying patent rights.

It is possible that defects of form in the preparation or filing of our patents or patent applications may exist, or may arise in the future, for example

with respect to proper priority claims, inventorship, claim scope, or patent term adjustments. If we or our partners, collaborators, licensees, or licensors,
whether current or future, fail to establish, maintain or protect such patents and other intellectual property rights, such rights may be reduced or eliminated.
If our partners, collaborators, licensees, or licensors are not fully cooperative or disagree with us as to the prosecution, maintenance or enforcement of any
patent rights, such patent rights could be compromised. If there are material defects in the form, preparation, prosecution, or enforcement of our patents or
patent applications,

63

such patents may be invalid and/or unenforceable, and such applications may never result in valid, enforceable patents. Any of these outcomes could impair
our ability to prevent competition from third parties, which may have an adverse impact on our business.

The patent position of biotechnology and pharmaceutical companies generally is highly uncertain. No consistent policy regarding the breadth of
claims allowed in biotechnology and pharmaceutical patents has emerged to date in the United States or in many foreign jurisdictions. In addition, the
determination of patent rights with respect to pharmaceutical compounds commonly involves complex legal and factual questions, which has in recent
years been the subject of much litigation. As a result, the issuance, scope, validity, enforceability and commercial value of our patent rights are highly
uncertain.

Pending patent applications cannot be enforced against third parties practicing the technology claimed in such applications unless and until a patent
issues from such applications. Assuming the other requirements for patentability are met, currently, the first to file a patent application is generally entitled
to the patent. However, prior to March 16, 2013, in the United States, the first to invent was entitled to the patent. Publications of discoveries in the
scientific literature often lag behind the actual discoveries, and patent applications in the United States and other jurisdictions are typically not published
until 18 months after filing, or in some cases not at all. Therefore, we cannot be certain that we were the first to make the inventions claimed in our patents
or pending patent applications, or that we were the first to file for patent protection of such inventions. Similarly, we cannot be certain that parties from
whom we do or may license or purchase patent rights were the first to make relevant claimed inventions or were the first to file for patent protection for
them. If third parties have filed patent applications on inventions claimed in our patents or applications on or before March 15, 2013, an interference
proceeding in the United States can be initiated by such third parties to determine who was the first to invent any of the subject matter covered by the patent
claims of our applications. If third parties have filed such applications after March 15, 2013, a derivation proceeding in the United States can be initiated by
such third parties to determine whether our invention was derived from theirs.

Moreover, because the issuance of a patent is not conclusive as to its inventorship, scope, validity or enforceability, our patents or pending patent

applications may be challenged in the courts or patent offices in the United States and abroad. There is no assurance that all of the potentially relevant prior
art relating to our patents and patent applications has been found. If such prior art exists, it may be used to invalidate a patent, or may prevent a patent from
issuing from a pending patent application. For example, such patent filings may be subject to a third-party preissuance submission of prior art to the U.S.
Patent and Trademark Office, or USPTO, or to other patent offices around the world. Alternately or additionally, we may become involved in post-grant
review procedures, oppositions, derivations, proceedings, reexaminations, inter partes review or interference proceedings, in the United States or elsewhere,
challenging patents or patent applications in which we have rights, including patents on which we rely to protect our business. An adverse determination in
any such challenges may result in loss of exclusivity or in patent claims being narrowed, invalidated or held unenforceable, in whole or in part, which could
limit our ability to stop others from using or commercializing similar or identical technology and products, or limit the duration of the patent protection of
our technology and products. In addition, given the amount of time required for the development, testing and regulatory review of new product candidates,
patents protecting such candidates might expire before or shortly after such candidates are commercialized. Furthermore, while it is our policy to require
our employees and contractors who may be involved in the conception or development of intellectual property to execute agreements assigning such
intellectual property to us, we may be unsuccessful in executing such an agreement with each party who, in fact, conceives or develops intellectual property
that we regard as our own. As a result, the inventorship or ownership of our intellectual property may be challenged in the future.

Pending and future patent applications may not result in patents being issued which protect our business, in whole or in part, or which effectively

prevent others from commercializing competitive products. Our issued patents or any patents that may issue in the future may be invalidated or interpreted
narrowly, such that they fail to provide us with any significant competitive advantage. Changes in either the patent laws or interpretation of the patent laws
in the United States and other countries may diminish the value of our patents or narrow the scope of our patent protection. In addition, the laws of foreign
countries may not protect our rights to the same extent or in the same manner as the laws of the United States. For example, patent laws in various
jurisdictions, including significant commercial markets such as Europe, restrict the patentability of methods of treatment of the human body more than
United States law does.

Issued patents that we have or may obtain or license may not provide us with any meaningful protection, prevent competitors from competing with

us or otherwise provide us with any competitive advantage. Our competitors may be able to circumvent our patents by developing similar or alternative
technologies or products in a non-infringing manner. Our competitors may also seek approval to market their own products similar to or otherwise
competitive with our products. Alternatively, our competitors may seek to market generic versions of any approved products by submitting ANDAs to the
FDA in which they claim that patents owned or licensed by us are invalid, unenforceable or not infringed. In these circumstances, we may need to defend
or assert our patents, or both, including by filing lawsuits alleging patent infringement. In any of these types of proceedings, a court or other agency with
jurisdiction may find our patents invalid or unenforceable or find that our competitors are competing in a non-infringing manner. Thus, even if we have
valid and enforceable patents, these patents still may not provide protection against competing products or processes sufficient to achieve our business
objectives.

64

Pursuant to the terms of some of our license agreements with third parties, some of our third-party licensors have the right, but not the obligation in

certain circumstances to control enforcement of our licensed patents or defense of any claims asserting the invalidity of these patents. Even if we are
permitted to pursue such enforcement or defense, we will require the cooperation of our licensors, and cannot guarantee that we would receive it and on
what terms. We cannot be certain that our licensors will allocate sufficient resources or prioritize their or our enforcement of such patents or defense of
such claims to protect our interests in the licensed patents. If we cannot obtain patent protection, or enforce existing or future patents against third parties,
our competitive position and our financial condition could suffer.

If we are unable to protect the confidentiality of our trade secrets, the value of our technology could be negatively impacted and our business would be
harmed.

In addition to the protection afforded by patents, we also rely on trade secret protection for certain aspects of our intellectual property. We seek to

protect these trade secrets, in part, by entering into non-disclosure and confidentiality agreements with parties who have access to them, such as our
employees, consultants, independent contractors, advisors, contract manufacturers, suppliers and other third parties. We also enter into confidentiality and
invention or patent assignment agreements with employees and certain consultants. Any party with whom we have executed such an agreement may breach
that agreement and disclose our proprietary information, including our trade secrets, and we may not be able to obtain adequate remedies for such breaches.
Enforcing a claim that a party illegally disclosed or misappropriated a trade secret is difficult, expensive and time-consuming, and the outcome is
unpredictable. Additionally, if the steps taken to maintain our trade secrets are deemed inadequate, we may have insufficient recourse against third parties
for misappropriating the trade secret. Further, if any of our trade secrets were to be lawfully obtained or independently developed by a competitor, we
would have no right to prevent such third party, or those to whom they communicate such technology or information, from using that technology or
information to compete with us. If any of our trade secrets were to be disclosed to or independently developed by a competitor, our business and
competitive position could be harmed.

We may become involved in lawsuits to protect or enforce our patents or other intellectual property, which could be expensive, time consuming and
unsuccessful.

Competitors may infringe our patents, trademarks, copyrights or other intellectual property. To counter infringement or unauthorized use, we may be

required to file infringement claims, which can be expensive and time consuming and divert the time and attention of our management and scientific
personnel. Any claims we assert against perceived infringers could provoke these parties to assert counterclaims against us alleging that we infringe their
patents, in addition to counterclaims asserting that our patents are invalid or unenforceable, or both. In any patent infringement proceeding, there is a risk
that a court will decide that a patent of ours is invalid or unenforceable, in whole or in part, and that we do not have the right to stop the other party from
using the invention at issue. There is also a risk that, even if the validity of such patents is upheld, the court will construe the patent’s claims narrowly or
decide that we do not have the right to stop the other party from using the invention at issue on the grounds that our patent claims do not cover the
invention. An adverse outcome in a litigation or proceeding involving one or more of our patents could limit our ability to assert those patents against those
parties or other competitors and may curtail or preclude our ability to exclude third parties from making and selling similar or competitive products.
Similarly, if we assert trademark infringement claims, a court may determine that the marks we have asserted are invalid or unenforceable, or that the party
against whom we have asserted trademark infringement has superior rights to the marks in question. In this case, we could ultimately be forced to cease use
of such trademarks.

Even if we establish infringement, the court may decide not to grant an injunction against further infringing activity and instead award only
monetary damages, which may or may not be an adequate remedy. Furthermore, because of the substantial amount of discovery required in connection with
intellectual property litigation, there is a risk that some of our confidential information could be compromised by disclosure during litigation. There could
also be public announcements of the results of hearings, motions or other interim proceedings or developments. If securities analysts or investors perceive
these results to be negative, it could adversely affect the price of shares of our common stock. Moreover, there can be no assurance that we will have
sufficient financial or other resources to file and pursue such infringement claims, which typically last for years before they are concluded. Even if we
ultimately prevail in such claims, the monetary cost of such litigation and the diversion of the attention of our management and scientific personnel could
outweigh any benefit we receive as a result of the proceedings.

If we are sued for infringing intellectual property rights of third parties, such litigation could be costly and time consuming and could prevent or delay
us from developing or commercializing our product candidates.

Our commercial success depends, in part, on our ability to develop, manufacture, market and sell our product candidates without infringing the

intellectual property and other proprietary rights of third parties. Third parties may have U.S. and non-U.S. issued patents and pending patent applications
relating to compounds and methods of use for the treatment of the disease indications for which we are developing our product candidates or relating to the
use of complement inhibition that may cover our product candidates or approach to complement inhibition. For example, we are aware of a U.S. patent
with claims that could be construed to cover

65

pegcetacoplan. Although we believe that these claims, if construed to cover pegcetacoplan, would be invalid due to various prior art disclosures available
more than a year before the priority date of the U.S. patent, there are no assurances that a court would agree. If any third-party patents or patent applications
are found to cover our product candidates or their methods of use or our approach to complement inhibition, we may not be free to manufacture or market
our product candidates as planned without obtaining a license, which may not be available on commercially reasonable terms, or at all.

There is a substantial amount of intellectual property litigation in the biotechnology and pharmaceutical industries, and we may become party to, or

threatened with, litigation or other adversarial proceedings regarding intellectual property rights with respect to our products candidates, including
interference proceedings before the USPTO. There may be third-party patents or patent applications with claims to materials, formulations, methods of
manufacture or methods for treatment related to the use or manufacture of our product candidates. Because patent applications can take many years to
issue, there may be currently pending patent applications which may later result in issued patents that our product candidates may be accused of infringing.
In addition, third parties may obtain patents in the future and claim that use of our technologies infringes upon these patents. Accordingly, third parties may
assert infringement claims against us based on existing or future intellectual property rights. The outcome of intellectual property litigation is subject to
uncertainties that cannot be adequately quantified in advance. The pharmaceutical and biotechnology industries have produced a significant number of
patents, and it may not always be clear to industry participants, including us, which patents cover various types of products or methods of use. The
coverage of patents is subject to interpretation by the courts, and the interpretation is not always uniform. If we were sued for patent infringement, we
would need to demonstrate that our product candidates, products or methods either do not infringe the patent claims of the relevant patent or that the patent
claims are invalid or unenforceable, and we may not be able to do this. Proving invalidity is difficult. For example, in the United States, proving invalidity
requires a showing of clear and convincing evidence to overcome the presumption of validity enjoyed by issued patents. Even if we are successful in these
proceedings, we may incur substantial costs and the time and attention of our management and scientific personnel could be diverted in pursuing these
proceedings, which could significantly harm our business and operating results. In addition, we may not have sufficient resources to bring these actions to a
successful conclusion.

If we are found to infringe a third party’s intellectual property rights, we could be forced, including by court order, to cease developing,

manufacturing or commercializing the infringing product candidate or product. Alternatively, we may be required to obtain a license from such third party
in order to use the infringing technology and continue developing, manufacturing or marketing the infringing product candidate or product. However, we
may not be able to obtain any required license on commercially reasonable terms or at all. Even if we were able to obtain a license, it could be non-
exclusive, thereby giving our competitors access to the same technologies licensed to us; alternatively or additionally it could include terms that impede or
destroy our ability to compete successfully in the commercial marketplace. In addition, we could be found liable for monetary damages, including treble
damages and attorneys’ fees if we are found to have willfully infringed a patent. A finding of infringement could prevent us from commercializing our
product candidates or force us to cease some of our business operations, which could harm our business. Claims that we have misappropriated the
confidential information or trade secrets of third parties could have a similar negative impact on our business.

Some of our intellectual property that was discovered through government-funded programs may be subject to federal regulation such as “march-in”
rights, certain reporting requirements, and a preference for U.S. industry. Compliance with such regulations may limit our exclusive rights, subject us
to expenditure of resources with respect to reporting requirements and limit our ability to contract with foreign manufacturers.

Some of our in-licensed intellectual property with respect to our product candidates has been funded in part by the U.S. government and, therefore,
would be subject to certain federal regulations pursuant to the Bayh-Dole Act of 1980, or the Bayh-Dole Act. As a result, the U.S. government may have
certain rights to intellectual property embodied in our current or future product candidates pursuant to the Bayh-Dole Act. The “march-in” provisions of the
Bayh-Dole Act allow, the U.S. government under strictly limited circumstances to require the patent owners to grant exclusive, partially exclusive or non-
exclusive rights to third parties for intellectual property discovered through the government-funded program. The U.S. government can exercise its march-
in rights if it determines that action is necessary because the patent owner fails to achieve practical application of the new invention or because action is
necessary to alleviate health concerns or address the safety needs of the public. Intellectual property discovered under the government-funded program is
also subject to certain reporting requirements, compliance with which may require us or our licensors to expend substantial resources. Such intellectual
property is also subject to a preference for U.S. industry, which may limit our ability to contract with foreign product manufacturers for products covered
by such intellectual property. Penn has requested a waiver of the U.S. manufacturing requirement, but there can be no assurance that such waiver will be
granted.  

66

Changes to the patent law in the United States and other jurisdictions could diminish the value of patents in general, thereby impairing our ability to
protect our products.

As is the case with other biopharmaceutical companies, our success is heavily dependent on intellectual property, particularly patents. Obtaining and

enforcing patents in the biopharmaceutical industry involves both technological and legal complexity and is therefore costly, time consuming and
inherently uncertain. Recent patent reform legislation in the United States, including the Leahy-Smith America Invents Act, or the America Invents Act,
could increase those uncertainties and costs. The America Invents Act was signed into law on September 16, 2011, and many of the substantive changes
became effective on March 16, 2013. The America Invents Act reformed United States patent law in part by changing the U.S. patent system from a “first
to invent” system to a “first inventor to file” system, expanding the definition of prior art, and developing a post-grant review system. This legislation
changes United States patent law in a way that may weaken our ability to obtain patent protection in the United States for those applications filed after
March 16, 2013.

Further, the America Invents Act created new procedures to challenge the validity of issued patents in the United States, including post-grant review

and inter partes review proceedings, which some third parties have been using to cause the cancellation of selected or all claims of issued patents of
competitors. For a patent with an effective filing date of March 16, 2013 or later, a petition for post-grant review can be filed by a third party in a nine-
month window from issuance of the patent. A petition for inter partes review can be filed immediately following the issuance of a patent if the patent has an
effective filing date prior to March 16, 2013. A petition for inter partes review can be filed after the nine-month period for filing a post-grant review
petition has expired for a patent with an effective filing date of March 16, 2013 or later. Post-grant review proceedings can be brought on any ground of
invalidity, whereas inter partes review proceedings can only raise an invalidity challenge based on published prior art and patents. These adversarial actions
at the USPTO review patent claims without the presumption of validity afforded to U.S. patents in lawsuits in U.S. federal courts and use a lower burden of
proof than used in litigation in U.S. federal courts. Therefore, it is generally considered easier for a competitor or third party to have a U.S. patent
invalidated in a USPTO post-grant review or inter partes review proceeding than invalidated in a litigation in a U.S. federal court. If any of our patents are
challenged by a third party in such a USPTO proceeding, there is no guarantee that we or our licensors or collaborators will be successful in defending the
patent, which would result in a loss of the challenged patent right to us.

The U.S. Supreme Court has ruled on several patent cases in recent years, either narrowing the scope of patent protection available in certain

circumstances or weakening the rights of patent owners in certain situations. Additionally, there have been recent proposals for additional changes to the
patent laws of the United States and other countries that, if adopted, could impact our ability to enforce our patents. In addition to increasing uncertainty
with regard to our ability to obtain patents in the future, this combination of events has created uncertainty with respect to the value of patents once
obtained. Depending on future actions by the U.S. Congress, the U.S. courts, the USPTO and the relevant law-making bodies in other countries, the laws
and regulations governing patents could change in unpredictable ways that would weaken our ability to obtain new patents or to enforce our existing
patents and patents that we might obtain in the future.

We may not be able to enforce our intellectual property rights throughout the world.

Filing, prosecuting and defending patents on our product candidates in all countries throughout the world would be prohibitively expensive, and our
intellectual property rights in some countries outside the United States are less extensive than those in the United States. The requirements for patentability
may differ in certain countries, particularly in developing countries; thus, even in countries where we do pursue patent protection, there can be no assurance
that any patents will issue with claims that cover our products. Competitors may use our technologies in jurisdictions where we have not pursued and
obtained patent protection to develop their own products and, further, may export otherwise infringing products to territories where we may obtain patent
protection, but where patent enforcement is not as strong as that in the United States. These products may compete with our products in jurisdictions where
we do not have any issued or licensed patents and any future patent claims or other intellectual property rights may not be effective or sufficient to prevent
them from so competing.

Moreover, our ability to protect and enforce our intellectual property rights may be adversely affected by unforeseen changes in foreign intellectual

property laws. Additionally, laws of some countries outside of the United States and Europe do not afford intellectual property protection to the same extent as
the laws of the United States and Europe. Many companies have encountered significant problems in protecting and defending intellectual property rights in
certain foreign jurisdictions. The legal systems of some countries, including India, China and other developing countries, do not favor the enforcement of patents
and other intellectual property rights. This could make it difficult for us to stop the infringement of our patents or the misappropriation of our other intellectual
property rights. For example, many foreign countries have compulsory licensing laws under which a patent owner must grant licenses to third parties.
Consequently, we may not be able to prevent third parties from practicing our inventions in certain countries outside the United States and Europe. Competitors
may use our technologies in jurisdictions where we have not obtained patent protection to develop and market their own products and, further, may export
otherwise infringing products to territories where we have patent protection, if our ability to enforce our patents to stop infringing activities is inadequate. These
products may compete with our products, and our patents or other intellectual property rights may not be effective or sufficient to prevent them from competing.

67

Agreements through which we license patent rights may not give us sufficient rights to permit us to pursue enforcement of our licensed patents or

defense of any claims asserting the invalidity of these patents (or control of enforcement or defense) of such patent rights in all relevant jurisdictions as
requirements may vary. For instance, under the Sobi collaboration, we retain the primary right to prosecute and defend its patent and other intellectual
property rights, but Sobi has the primary right to enforce such rights against competitive infringement outside the United States.

Proceedings to enforce our patent rights in foreign jurisdictions, whether or not successful, could result in substantial costs and divert our efforts and
resources from other aspects of our business. Moreover, such proceedings could put our patents at risk of being invalidated or interpreted narrowly and our
patent applications at risk of not issuing and could provoke third parties to assert claims against us. We may not prevail in any lawsuits that we initiate and
the damages or other remedies awarded, if any, may not be commercially meaningful. Furthermore, while we intend to protect our intellectual property
rights in major markets for our products, we cannot ensure that we will be able to initiate or maintain similar efforts in all jurisdictions in which we may
wish to market our products. Accordingly, our efforts to protect our intellectual property rights in such countries may be inadequate.

If we do not obtain patent term extension and data exclusivity for any product candidates we may develop, our business may be materially harmed.

Depending upon the timing, duration and specifics of any FDA marketing approval of any product candidates we may develop, one or more of our

U.S. patents may be eligible for limited patent term extension under the Drug Price Competition and Patent Term Restoration Action of 1984, or Hatch-
Waxman Amendments. The Hatch-Waxman Amendments permit a patent term extension of up to five years as compensation for patent term lost during the
FDA regulatory review process. A patent term extension cannot extend the remaining term of a patent beyond 14 years from the date of product approval,
only one patent may be extended and the extension only applies to those claims covering the approved drug, a method for using it, or a method for
manufacturing it. However, we may not be granted an extension because of, for example, failing to exercise due diligence during the testing phase or
regulatory review process, failing to apply within applicable deadlines, failing to apply prior to expiration of relevant patents, or otherwise failing to satisfy
applicable requirements. Moreover, the applicable time period or the scope of patent protection afforded could be less than we request. If we are unable to
obtain patent term extension or the term of any such extension is less than we request, our competitors may obtain approval of competing products
following our patent expiration, and our business, financial condition, results of operations and prospects could be materially harmed.

We may be subject to claims by third parties asserting that our employees or we have misappropriated their intellectual property or claiming ownership
of what we regard as our own intellectual property.

Many of our employees, including our senior management, were previously employed at universities or at other biotechnology or pharmaceutical

companies, including some which may be competitors or potential competitors. Some of these employees, including each member of our senior
management, executed proprietary rights, non-disclosure, non-competition and non-solicitation agreements, or similar agreements, in connection with such
previous employment. Although we try to ensure that our employees do not use the proprietary information or know-how of others in their work for us, we
may be subject to claims that we or these employees have used or disclosed intellectual property, including trade secrets or other proprietary information, of
any such third party. Litigation may be necessary to defend against such claims. If we fail in defending any such claims, in addition to paying monetary
damages, we may lose valuable intellectual property rights or personnel or sustain damages. Such intellectual property rights could be awarded to a third
party, and we could be required to obtain a license from such third party to commercialize our technology or products. Such a license may not be available
on commercially reasonable terms or at all. Even if we are successful in defending against such claims, litigation could result in substantial costs and be a
distraction to management.

In addition, while we typically require our employees, consultants and contractors who may be involved in the development of intellectual property

to execute agreements assigning such intellectual property to us, we may be unsuccessful in executing such an agreement with each party who in fact
develops intellectual property that we regard as our own, which may result in claims by or against us related to the ownership of such intellectual property.
If we fail in prosecuting or defending any such claims, in addition to paying monetary damages, we may lose valuable intellectual property rights. Even if
we are successful in prosecuting or defending against such claims, litigation could result in substantial costs and be a distraction to our senior management
and scientific personnel.

68

Obtaining and maintaining patent protection depends on compliance with various procedural, document submission, fee payment and other
requirements imposed by governmental patent agencies, and our patent protection could be reduced or eliminated for non-compliance with these
requirements.

Periodic maintenance fees, renewal fees, annuity fees and various other governmental fees on patents and applications are required to be paid to the

USPTO and various governmental patent agencies outside of the United States in several stages over the lifetime of the patents and applications. The
USPTO and various non-U.S. governmental patent agencies require compliance with a number of procedural, documentary, fee payment and other similar
provisions during the patent application process and after a patent has issued. While an inadvertent lapse can in many cases be cured by payment of a late
fee or by other means in accordance with the applicable rules, there are situations in which non-compliance can result in abandonment or lapse of the patent
or patent application, resulting in partial or complete loss of patent rights in the relevant jurisdiction. Non-compliance events that could result in
abandonment or lapse of a patent or patent application include, but are not limited to, the failure to respond to official actions within prescribed time limits,
non-payment of fees and failure to properly legalize and submit formal documents. If we fail to maintain the patents and patent applications covering our
product candidates, our competitive position would be adversely affected.

If we are unable to obtain licenses from third parties on commercially reasonable terms or fail to comply with our obligations under such agreements,
our business could be harmed.

It may be necessary for us to use the patented or proprietary technology of third parties to commercialize our products, in which case we would be

required to obtain a license from these third parties. If we are unable to license such technology, or if we are forced to license such technology on
unfavorable terms, our business could be materially harmed. If we are unable to obtain a necessary license, we may be unable to develop or commercialize
the affected product candidates, which could materially harm our business and the third parties owning such intellectual property rights could seek either an
injunction prohibiting our sales, or, with respect to our sales, an obligation on our part to pay royalties and/or other forms of compensation. Even if we are
able to obtain a license, it may be non-exclusive, which could enable our competitors to obtain access to the same technologies licensed to us.

If we fail to comply with our obligations under license agreements, our counterparties may have the right to terminate these agreements, in which

event we might not be able to develop, manufacture or market, or may be forced to cease developing, manufacturing or marketing, any product that is
covered by these agreements or may face other penalties under such agreements. Such an occurrence could materially adversely affect the value of the
product candidate being developed under any such agreement. Termination of these agreements or reduction or elimination of our rights under these
agreements may result in our having to negotiate new or reinstated agreements with less favorable terms, cause us to lose our rights under these
agreements, including our rights to important intellectual property or technology, or impede, delay or prohibit the further development or
commercialization of one or more product candidates that rely on such agreements.

Risks Related to Regulatory Approval and Marketing of Our Product Candidates and Other Legal Compliance Matters

The regulatory approval process is expensive, time consuming and uncertain and may prevent us or our collaborators such as Sobi from obtaining
approvals for the commercialization of pegcetacoplan or any of our product candidates that we develop. As a result, we cannot predict when or if, and
in which territories, we, or our collaborators, will obtain marketing approval to commercialize pegcetacoplan or any other product candidate that we
develop.

The research, testing, manufacturing, labeling, approval, selling, marketing, promotion and distribution of products are subject to extensive

regulation by the FDA and comparable foreign regulatory authorities. We are not permitted to market our product candidates in the United States or in
other countries until we, or they, receive approval of an NDA from the FDA or marketing approval from applicable regulatory authorities outside the
United States. Our product candidates are in various stages of development and are subject to the risks of failure inherent in drug development. In
September 2020, we submitted an NDA to the FDA and a MAA to the EMA for pegcetacoplan for the treatment of PNH. We have limited experience in
conducting and managing the clinical trials necessary to obtain marketing approvals, including FDA approval of an NDA.

The process of obtaining marketing approvals, both in the United States and abroad, is lengthy, expensive and uncertain. It may take many years, if
approval is obtained at all, and can vary substantially based upon a variety of factors, including the type, complexity and novelty of the product candidates
involved. Securing marketing approval requires the submission of extensive preclinical and clinical data and supporting information, including
manufacturing information, to regulatory authorities for each therapeutic indication to establish the product candidate’s safety and efficacy. The FDA or
other regulatory authorities may determine that our product candidates are not safe and effective, only moderately effective or have undesirable or
unintended side effects, toxicities or other characteristics that preclude our obtaining marketing approval or prevent or limit commercial use. Any
marketing approval we ultimately obtain may be limited or subject to restrictions or post-approval commitments that render the approved product not
commercially viable.

69

In addition, changes in marketing approval policies during the development period, changes in or the enactment or promulgation of additional
statutes, regulations or guidance or changes in regulatory review for each submitted product application, may cause delays in the approval or rejection of an
application. Regulatory authorities have substantial discretion in the approval process and may refuse to accept any application or may decide that our data
are insufficient for approval and require additional preclinical, clinical or other studies. In addition, varying interpretations of the data obtained from
preclinical and clinical testing could delay, limit or prevent marketing approval of a product candidate. Any marketing approval we, or our collaborators,
ultimately obtain may be limited or subject to restrictions or post-approval commitments that render the approved product not commercially viable. In
addition, to the extent that we seek to develop a combination drug-device product for delivery of a product candidate or we rely on a previously cleared
device to deliver a product candidate, we will also be dependent on FDA clearance or approval of such products.

Finally, disruptions at the FDA and other agencies may prolong the time necessary for new drugs to be reviewed and/or approved by necessary
government agencies, which would adversely affect our business. For example, over the last several years, the U.S. government has shut down several
times and certain regulatory agencies, such as the FDA, have had to furlough critical employees and stop critical activities. If a prolonged government
shutdown occurs, it could significantly impact the ability of the FDA to timely review and process our regulatory submissions, which could have a material
adverse effect on our business.  The Trump Administration also took several executive actions that could impose significant burdens on, or otherwise
materially delay, the FDA’s ability to engage in routine regulatory and oversight activities.

Under our agreement with Sobi, Sobi is responsible for seeking regulatory approval outside the United States for systemic pegcetacoplan. A delay in

obtaining or failure to obtain required approvals and clearances could negatively impact our ability or that of our collaborators, including Sobi, to generate
revenue from the particular product candidate, which likely would result in significant harm to our financial position and adversely impact our stock price.

Failure to obtain marketing approval in foreign jurisdictions would prevent our product candidates from being marketed abroad. Any approval we are
granted for our product candidates in the United States would not assure approval of our product candidates in foreign jurisdictions.

In order to market and sell pegcetacoplan or any of our other products in the European Union and other foreign jurisdictions, we, and our
collaborators, such as Sobi, must obtain separate marketing approvals and comply with numerous and varying regulatory requirements. The approval
procedure varies among countries and can involve additional testing. The time required to obtain approval may differ substantially from that required to
obtain FDA approval. The marketing approval process outside the United States generally includes all of the risks associated with obtaining FDA approval.
In addition, in many countries outside the United States, a product must be approved for reimbursement before the product can be approved for sale in that
country. We, and our collaborators, such as Sobi, may not obtain approvals from regulatory authorities outside the United States on a timely basis, if at all.
Approval by the FDA does not ensure approval by regulatory authorities in other countries or jurisdictions, and approval by one regulatory authority
outside the United States does not ensure approval by regulatory authorities in other countries or jurisdictions or by the FDA. We may file for marketing
approvals but not receive necessary approvals to commercialize our products in any market.

Additionally, we could face heightened risks with respect to seeking marketing approval in the United Kingdom as a result of the recent withdrawal

of the United Kingdom from the European Union, commonly referred to as Brexit.  Pursuant to the formal withdrawal arrangements agreed between the
United Kingdom and the European Union, the United Kingdom withdrew from the European Union, effective December 31, 2020.  On December 24, 2020,
the United Kingdom and the European Union entered into a Trade and Cooperation Agreement.  The agreement sets out certain procedures for approval
and recognition of medical products in each jurisdiction. Since the regulatory framework for pharmaceutical products in the United Kingdom covering the
quality, safety, and efficacy of pharmaceutical products, clinical trials, marketing authorization, commercial sales, and distribution of pharmaceutical
products is derived from European Union directives and regulations, Brexit could materially impact the future regulatory regime that applies to products
and the approval of product candidates in the United Kingdom. Any delay in obtaining, or an inability to obtain, any marketing approvals, as a result of
Brexit or otherwise, would prevent us from commercializing any product candidates in the United Kingdom and/or the European Union and restrict our
ability to generate revenue and achieve and sustain profitability. If any of these outcomes occur, we may be forced to restrict or delay efforts to seek
regulatory approval in the United Kingdom and/or European Union for any product candidates, which could significantly and materially harm our business.

We, or our collaborators, may not be able to obtain orphan drug designation or orphan drug exclusivity for our product candidates and, even if we do,
that exclusivity may not prevent the FDA or the EMA from approving other competing products.

Regulatory authorities in some jurisdictions, including the United States and Europe, may designate drugs for relatively small patient populations as

orphan drugs. Under the Orphan Drug Act, the FDA may designate a product as an orphan drug if it is a drug intended to treat a rare disease or condition,
which is generally defined as a patient population of fewer than 200,000 individuals annually in the United States. The FDA has granted orphan drug
designation to pegcetacoplan for the treatment of PNH and for the treatment of C3 glomerulopathy. We, or our collaborators, may seek orphan drug
designations for pegcetacoplan for other indications and for other product candidates and may be unable to obtain such designations.

70

Even if we, or our collaborators, obtain orphan drug designation for a product candidate, such as is the case for pegcetacoplan for the treatment of

PNH, we, or they, may not be able to obtain orphan drug exclusivity for that product candidate. Generally, a product with orphan drug designation only
becomes entitled to orphan drug exclusivity if it receives the first marketing approval for the indication for which it has such designation, in which case the
FDA or the EMA will be precluded from approving another marketing application for the same drug for that indication for the applicable exclusivity
period. The applicable exclusivity period is seven years in the United States and ten years in Europe. The European exclusivity period can be reduced to six
years if a drug no longer meets the criteria for orphan drug designation or if the drug is sufficiently profitable so that market exclusivity is no longer
justified. Orphan drug exclusivity may be lost if the FDA or the EMA determines that the request for designation was materially defective or if the
manufacturer is unable to assure sufficient quantity of the drug to meet the needs of patients with the rare disease or condition.

Even if we, or our collaborators, obtain orphan drug exclusivity for a product, that exclusivity may not effectively protect the product from

competition because different drugs can be approved for the same condition. Even after an orphan drug is approved, the FDA can subsequently approve the
same drug for the same condition if the FDA concludes that the later drug is clinically superior in that it is shown to be safer, more effective or makes a
major contribution to patient care.

The FDA may further reevaluate the Orphan Drug Act and its regulations and policies. We do not know if, when, or how the FDA may change the

orphan drug regulations and policies in the future, and it is uncertain how any changes might affect our business. Depending on what changes the FDA may
make to its orphan drug regulations and policies, our business could be adversely impacted.

Fast track designation for one or more of our product candidates may not actually lead to a faster development or regulatory review or approval
process.

We have received fast track designations for pegcetacoplan for the treatment of PNH and GA. If a product is intended for the treatment of a serious
condition and nonclinical or clinical data demonstrate the potential to address unmet medical need for this condition, a product sponsor may apply for FDA
fast track designation. Even though we have received fast track designation for pegcetacoplan for the treatment of PNH and GA, fast track designation does
not ensure that we will receive marketing approval or that approval will be granted within any particular timeframe. We may not experience a faster
development or regulatory review or approval process with fast rack designation compared to conventional FDA procedures. In addition, the FDA may
withdraw fast track designation if it believes that the designation is no longer supported by data from our clinical development program. Fast track
designation alone does not guarantee qualification for the FDA’s priority review procedures.

Even if we, or our collaborators, obtain marketing approvals for our product candidates, the terms of approvals and ongoing regulation of our products
may limit how we manufacture and market our products, which could impair our ability to generate revenue.

Once marketing approval has been granted, an approved product and its manufacturer and marketer are subject to ongoing review and extensive

regulation. We, and our collaborators, must therefore comply with requirements concerning advertising and promotion for any of our product candidates
which we or they market. Promotional communications with respect to prescription drugs are subject to a variety of legal and regulatory restrictions and
must be consistent with the information in the product’s approved labeling. Thus, we and our collaborators will not be able to promote any products we
develop for indications or uses for which they are not approved.

In addition, manufacturers of approved products and those manufacturers’ facilities are required to comply with extensive FDA requirements,
including ensuring that quality control and manufacturing procedures conform to cGMPs, which include requirements relating to quality control and
quality assurance as well as the corresponding maintenance of records and documentation and reporting requirements. We, our contract manufacturers, our
collaborators and their contract manufacturers could be subject to periodic unannounced inspections by the FDA to monitor and ensure compliance with
cGMPs.

Accordingly, assuming we, or our collaborators, receive marketing approval for one or more of our product candidates, we, and our collaborators,
and our and their contract manufacturers will continue to expend time, money and effort in all areas of regulatory compliance, including manufacturing,
production, product surveillance and quality control.

If we, and our collaborators, are not able to comply with post-approval regulatory requirements, we, and our collaborators, could have the marketing
approvals for our products withdrawn by regulatory authorities and our, or our collaborators’, ability to market any future products could be limited, which
could adversely affect our ability to achieve or sustain profitability. Further, the cost of compliance with post-approval regulations may have a negative
effect on our operating results and financial condition.

Any of our product candidates for which we, or our collaborators, obtain marketing approval in the future could be subject to post-marketing
restrictions or withdrawal from the market and we, or our collaborators, may be subject to substantial penalties if we, or

71

they, fail to comply with regulatory requirements or if we, or they, experience unanticipated problems with our products following approval.

Any of our product candidates for which we, or our collaborators, obtain marketing approval, as well as the manufacturing processes, post-approval
studies and measures, labeling, advertising and promotional activities for such product, among other things, will be subject to ongoing requirements of and
review by the FDA and other regulatory authorities. These requirements include submissions of safety and other post-marketing information and reports,
registration and listing requirements, requirements relating to manufacturing, quality control, quality assurance and corresponding maintenance of records
and documents, requirements regarding the distribution of samples to physicians and recordkeeping. Even if marketing approval of a product candidate is
granted, the approval may be subject to limitations on the indicated uses for which the product may be marketed or to the conditions of approval, including
the requirement to implement a Risk Evaluation and Mitigation Strategy.

The FDA may also impose requirements for costly post-marketing studies or clinical trials and surveillance to monitor the safety or efficacy of a
product. The FDA and other agencies, including the Department of Justice, closely regulate and monitor the post-approval marketing and promotion of
products to ensure that they are manufactured, marketed and distributed only for the approved indications and in accordance with the provisions of the
approved labeling. The FDA imposes stringent restrictions on manufacturers’ communications regarding off-label use and if we, or our collaborators, do
not market any of our product candidates for which we, or they, receive marketing approval for only their approved indications, we, or they, may be subject
to warnings or enforcement action for off-label marketing. Violation of the FDCA and other statutes, including the False Claims Act, relating to the
promotion and advertising of prescription drugs may lead to investigations or allegations of violations of federal and state health care fraud and abuse laws
and state consumer protection laws.

In addition, later discovery of previously unknown adverse events or other problems with our products or their manufacturers or manufacturing

processes, or failure to comply with regulatory requirements, may yield various results, including:

•

•

•

•

•

•

•

•

•

•

•

•

•

•

restrictions on such products, manufacturers or manufacturing processes;

restrictions on the labeling or marketing of a product;

restrictions on product distribution or use;

requirements to conduct post-marketing studies or clinical trials;

warning letters or untitled letters;

withdrawal of the products from the market;

refusal to approve pending applications or supplements to approved applications that we submit;

recall of products;

restrictions on coverage by third-party payors;

fines, restitution or disgorgement of profits or revenues;

suspension or withdrawal of marketing approvals;

refusal to permit the import or export of products;

product seizure; or

injunctions or the imposition of civil or criminal penalties.

Current and future legislation may increase the difficulty and cost for us and our collaborators to obtain marketing approval of and commercialize our
product candidates and affect the prices we, or they, may obtain.

In the United States and some foreign jurisdictions, there have been and continue to be a number of legislative and regulatory changes and proposed
changes regarding the healthcare system that could, among other things, prevent or delay marketing approval of our product candidates, restrict or regulate
post-approval activities and affect our ability, or the ability of our collaborators, to profitably sell any products for which we, or they, obtain marketing
approval. We expect that current laws, as well as other healthcare reform measures that may be adopted in the future, may result in more rigorous coverage
criteria and in additional downward pressure on the price that we, or our collaborators, may receive for any approved products.

In March 2010, President Obama signed into law the Patient Protection and Affordable Care Act, as amended by the Health Care and Education

Reconciliation Act of 2010, or collectively the ACA. In addition, other legislative changes have been proposed and adopted since the ACA was enacted. In
August 2011, the Budget Control Act of 2011, among other things, created measures for spending reductions by Congress. A Joint Select Committee on
Deficit Reduction, tasked with recommending a targeted deficit

72

 
 
 
 
 
 
 
 
 
 
 
 
 
 
reduction of at least $1.2 trillion for the years 2013 through 2021, was unable to reach required goals, thereby triggering the legislation’s automatic
reduction to several government programs. These changes included aggregate reductions to Medicare payments to providers of up to 2% per fiscal year,
which went into effect in April 2013 and will remain in effect through 2029 unless additional Congressional action is taken. The Coronavirus Aid, Relief,
and Economic Security Act, or the CARES Act, suspended the 2% Medicare sequester from May 1, 2020 through December 31, 2020, and extended the
sequester by one year, through 2030. The American Taxpayer Relief Act of 2012, among other things, reduced Medicare payments to several providers and
increased the statute of limitations period for the government to recover overpayments to providers from three to five years. These new laws may result in
additional reductions in Medicare and other healthcare funding and otherwise affect the prices we may obtain for any of our product candidates for which
we may obtain regulatory approval or the frequency with which any such product candidate is prescribed or used.

Since enactment of the ACA, there have been, and continue to be, numerous legal challenges and Congressional actions to repeal and replace
provisions of the law. For example, with enactment of the Tax Cuts and Jobs Act of 2017 (the “TCJA”), Congress repealed the “individual mandate.” The
repeal of this provision, which requires most Americans to carry a minimal level of health insurance, became effective in 2019.  Further, on December 14,
2018, a U.S. District Court judge in the Northern District of Texas ruled that the individual mandate portion of the ACA is an essential and inseverable
feature of the ACA, and therefore because the mandate was repealed as part of the Tax Cuts and Jobs Act, the remaining provisions of the ACA are invalid
as well. On December 18, 2019, the Court of Appeals for the Fifth Circuit court affirmed the lower court’s ruling that the individual mandate portion of the
ACA is unconstitutional and it remanded the case to the district court for reconsideration of the severability question and additional analysis of the
provisions of the ACA.  Thereafter, the U.S. Supreme Court agreed to hear this case. Oral argument in the case took place on November 10, 2020.  On
February 10, 2021, the Biden Administration withdrew the federal government’s support for overturning the ACA.  A ruling by the Court is expected
sometime this year. Litigation and legislation over the ACA are likely to continue, with unpredictable and uncertain results.

The Trump Administration also took executive actions to undermine or delay implementation of the ACA, including  directing federal agencies with
authorities and responsibilities under the ACA to waive, defer, grant exemptions from, or delay the implementation of any provision of the ACA that would
impose a fiscal or regulatory burden on states, individuals, healthcare providers, health insurers, or manufacturers of pharmaceuticals or medical
devices.  On January 28, 2021, however, President Biden issued a new Executive Order which directs federal agencies to reconsider rules and other policies
that limit Americans’ access to health care, and consider actions that will protect and strengthen that access.  Under this Order, federal agencies are directed
to re-examine: policies that undermine protections for people with pre-existing conditions, including complications related to COVID-19; demonstrations
and waivers under Medicaid and the ACA that may reduce coverage or undermine the programs, including work requirements; policies that undermine the
Health Insurance Marketplace or other markets for health insurance; policies that make it more difficult to enroll in Medicaid and the ACA; and policies
that reduce affordability of coverage or financial assistance, including for dependents. This Executive Order also directs the U.S. Department of Health and
Human Services to create a special enrollment period for the Health Insurance Marketplace in response to the COVID-19 pandemic.

The prices of prescription pharmaceuticals in the United States and foreign jurisdictions is subject to considerable legislative and executive actions and
could impact the prices we obtain for our products, if and when licensed.

The prices of prescription pharmaceuticals have also been the subject of considerable discussion in the United States.  To date, there have been
several recent U.S. congressional inquiries, as well as proposed and enacted state and federal legislation designed to, among other things, bring more
transparency to drug pricing, review the relationship between pricing and manufacturer patient programs, reduce the costs of drugs under Medicare and
reform government program reimbursement methodologies for products.  To those ends, the Trump Administration issued several executive orders intended
to lower the costs of prescription drug products. Certain of these orders are reflected in recently promulgated regulations, including an interim final rule
implementing the Trump Administration’s most favored nation model, but such final rule is currently subject to a nationwide preliminary injunction.  It
remains to be seen whether these orders and resulting regulations will remain in force during the Biden Administration.  Further, on September 24, 2020,
the Trump Administration finalized a rulemaking allowing states or certain other non-federal government entities to submit importation program proposals
to the FDA for review and approval. Applicants are required to demonstrate that their importation plans pose no additional risk to public health and safety
and will result in significant cost savings for consumers.  The FDA has issued draft guidance that would allow manufacturers to import their own FDA-
approved drugs that are authorized for sale in other countries (multi-market approved products).  

At the state level, individual states are increasingly aggressive in passing legislation and implementing regulations designed to control

pharmaceutical and biological product pricing, including price or patient reimbursement constraints, discounts, restrictions on certain product access and
marketing cost disclosure and transparency measures, and, in some cases, designed to encourage importation from other countries and bulk purchasing. In
addition, regional health care organizations  and individual hospitals are increasingly using bidding procedures to determine what pharmaceutical products
and which suppliers will be included in their prescription drug and other health care programs. These measures could reduce the ultimate demand for our
products, once approved,

73

or put pressure on our product pricing.  We expect that additional state and federal healthcare reform measures will be adopted in the future, any of which
could limit the amounts that federal and state governments will pay for healthcare products and services, which could result in reduced demand for our
product candidates or additional pricing pressures.

In countries outside of the United States, particularly the countries of the European Union, the pricing of prescription pharmaceuticals is subject to

governmental control. In these countries, pricing negotiations with governmental authorities can take considerable time after the receipt of marketing
approval for a product. To obtain reimbursement or pricing approval in some countries, we may be required to conduct a clinical trial that compares the
cost-effectiveness of our product candidate to other available therapies. If reimbursement of our products is unavailable or limited in scope or amount, or if
pricing is set at unsatisfactory levels, our business could be harmed, possibly materially.

Our relationships with customers and third-party payors, among others, will be subject to applicable anti-kickback, fraud and abuse and other
healthcare laws and regulations, which could expose us to penalties, including criminal sanctions, civil penalties, contractual damages, reputational
harm, fines, disgorgement, exclusion from participation in government healthcare programs, curtailment or restricting of our operations, and
diminished profits and future earnings.

Healthcare providers, physicians and third-party payors will play a primary role in the recommendation and prescription of any products for which
we obtain marketing approval. Our current and future arrangements with healthcare providers, and third-party payors and customers, if any, will subject us
to broadly applicable fraud and abuse and other healthcare laws and regulations. The laws and regulations may constrain the business or financial
arrangements and relationships through which we conduct clinical research, market, sell and distribute any products for which we obtain marketing
approval. These include the following:

Anti-Kickback Statute. The federal Anti-Kickback Statute prohibits, among other things, persons and entities from knowingly and willfully
soliciting, offering, receiving or providing remuneration (including any kickback, bribe or rebate), directly or indirectly, in cash or in kind, to induce or
reward, or in return for, either the referral of an individual for, or the purchase, lease or order of a good, facility, item or service for which payment may be
made under a federal healthcare program such as Medicare and Medicaid;

False Claims Laws. The federal false claims and civil monetary penalties laws, including the federal civil False Claims Act, impose criminal and
civil penalties, including through civil whistleblower or qui tam actions against individuals or entities for, among other things, knowingly presenting or
causing to be presented false or fraudulent claims for payment by a federal healthcare program or making a false statement or record material to payment of
a false claim or avoiding, decreasing or concealing an obligation to pay money to the federal government, with potential liability including mandatory
treble damages and significant per-claim penalties;

HIPAA. The federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, imposes criminal and civil liability for, among other

things, executing a scheme, or making materially false statements in connection with the delivery of or payment for health care benefits, items, or services.
Additionally, HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act and its implementing regulations, also
imposes obligations on covered entities and their business associates that perform certain functions or activities that involve the use or disclosure of
protected health information on their behalf, including mandatory contractual terms and technical safeguards, with respect to maintaining the privacy,
security and transmission of individually identifiable health information;

Transparency Requirements. The federal Physician Payments Sunshine Act requires certain manufacturers of drugs, devices, biologics, and medical
supplies for which payment is available under Medicare, Medicaid, or the Children’s Health Insurance Program, with specific exceptions, to report annually
to the Centers for Medicare & Medicaid Services, or CMS, information related to payments or transfers of value made to physicians and teaching hospitals,
as well as information regarding ownership and investment interests held by physicians and their immediate family members; and

Analogous State and Foreign Laws. Analogous state and foreign fraud and abuse laws and regulations, such as state anti-kickback and false claims
laws, can apply to sales or marketing arrangements, and claims involving healthcare items or services reimbursed by non-governmental third-party payors,
and are generally broad and are enforced by many different federal and state agencies as well as through private actions. Some state laws require
pharmaceutical companies to comply with the pharmaceutical industry’s voluntary compliance guidelines and the relevant compliance guidance
promulgated by the federal government and require drug manufacturers to report information related to payments and other transfers of value to physicians
and other healthcare providers or marketing expenditures. Additionally, some state and local laws require the registration of pharmaceutical sales
representatives in the jurisdiction. State and foreign laws also govern the privacy and security of health information in some circumstances, many of which
differ from each other in significant ways and often are not pre-empted by HIPAA, thus complicating compliance efforts.

Because of the breadth of these laws and the narrowness of the statutory exceptions and safe harbors available, it is possible that some of our
business activities could be subject to challenge under one or more of such laws. If our operations are found to be in violation of any of the laws described
above or any other government regulations that apply to us, we may be subject to penalties, including civil and criminal penalties, damages, fines,
exclusion from participation in government healthcare programs, such as

74

Medicare and Medicaid, imprisonment and the curtailment or restructuring of our operations, any of which could adversely affect our business, financial
condition, results of operations and prospects.

The provision of benefits or advantages to physicians to induce or encourage the prescription, recommendation, endorsement, purchase, supply,

order or use of medicinal products is prohibited in the European Union. The provision of benefits or advantages to physicians is also governed by the
national anti-bribery laws of European Union Member States, such as the UK Bribery Act 2010. Violation of these laws could result in substantial fines and
imprisonment.

Payments made to physicians in certain European Union Member States must be publicly disclosed. Moreover, agreements with physicians often
must be the subject of prior notification and approval by the physician’s employer, his or her competent professional organization and/or the regulatory
authorities of the individual European Union Member States.

These requirements are provided in the national laws, industry codes or professional codes of conduct applicable in the European Union Member

States. Failure to comply with these requirements could result in reputational risk, public reprimands, administrative penalties, fines or imprisonment.

Efforts to ensure that our business arrangements with third parties, and our business generally, will comply with applicable healthcare laws and
regulations will involve substantial costs. It is possible that governmental authorities will conclude that our business practices may not comply with current
or future statutes, regulations or case law involving applicable fraud and abuse or other healthcare laws and regulations. If our operations are found to be in
violation of any of these laws or any other governmental regulations that may apply to us, we may be subject to significant civil, criminal and
administrative penalties, damages, fines, individual imprisonment, additional reporting requirements and oversight if we become subject to a corporate
integrity agreement or similar agreement to resolve allegations of non-compliance with these laws, exclusion of products from government funded
healthcare programs, such as Medicare and Medicaid, disgorgement, contractual damages, reputational harm, and the curtailment or restructuring of our
operations. Defending against any such actions can be costly, time-consuming and may require significant financial and personnel resources. Therefore,
even if we are successful in defending against any such actions that may be brought against us, our business may be impaired. Further, if any of the
physicians or other healthcare providers or entities with whom we expect to do business is found to be not in compliance with applicable laws, they may be
subject to criminal, civil or administrative sanctions, including exclusions from government funded healthcare programs. Liabilities they incur pursuant to
these laws could result in significant costs or an interruption in operations, which could have a material adverse effect on our business, financial condition,
results of operations and prospects.

Compliance with global privacy and data security requirements could result in additional costs and liabilities to us or inhibit our ability to collect and
process data globally, and the failure to comply with such requirements could subject us to significant fines and penalties, which may have a material
adverse effect on our business, financial condition or results of operations.

The regulatory framework for the collection, use, safeguarding, sharing, transfer and other processing of information worldwide is rapidly evolving
and is likely to remain uncertain for the foreseeable future. Globally, virtually every jurisdiction in which we operate has established its own data security
and privacy frameworks with which we must comply. For example, the collection, use, disclosure, transfer, or other processing of personal data regarding
individuals in the European Union, including personal health data, is subject to the EU General Data Protection Regulation, or the GDPR, which took effect
across all member states of the European Economic Area, or EEA, in May 2018. The GDPR is wide-ranging in scope and imposes numerous requirements
on companies that process personal data, including requirements relating to processing health and other sensitive data, obtaining consent of the individuals
to whom the personal data relates, providing information to individuals regarding data processing activities, implementing safeguards to protect the security
and confidentiality of personal data, providing notification of data breaches, and taking certain measures when engaging third-party processors. The GDPR
increases our obligations with respect to clinical trials conducted in the EEA by expanding the definition of personal data to include coded data and
requiring changes to informed consent practices and more detailed notices for clinical trial subjects and investigators. In addition, the GDPR also imposes
strict rules on the transfer of personal data to countries outside the European Union, including the United States and, as a result, increases the scrutiny that
clinical trial sites located in the EEA should apply to transfers of personal data from such sites to countries that are considered to lack an adequate level of
data protection, such as the United States. The GDPR also permits data protection authorities to require destruction of improperly gathered or used personal
information and/or impose substantial fines for violations of the GDPR, which can be up to four percent of global revenues or 20 million Euros, whichever
is greater, and it also confers a private right of action on data subjects and consumer associations to lodge complaints with supervisory authorities, seek
judicial remedies, and obtain compensation for damages resulting from violations of the GDPR. In addition, the GDPR provides that European Union
member states may make their own further laws and regulations limiting the processing of personal data, including genetic, biometric or health data.  

Similar actions are either in place or under way in the United States. There are a broad variety of data protection laws that are applicable to our

activities, and a wide range of enforcement agencies at both the state and federal levels that can review companies for privacy and data security concerns
based on general consumer protection laws. The Federal Trade Commission and state Attorneys General all are aggressive in reviewing privacy and data
security protections for consumers. New laws also are being considered at both the state and federal levels. For example, the California Consumer Privacy
Act—which went into effect on January 1, 2020—is creating similar risks and obligations as those created by GDPR, though the Act does exempt certain
information collected as part of a

75

clinical trial subject to the Federal Policy for the Protection of Human Subjects (the Common Rule). Many other states are considering similar legislation.
A broad range of legislative measures also have been introduced at the federal level. Accordingly, failure to comply with federal and state laws (both those
currently in effect and future legislation) regarding privacy and security of personal information could expose us to fines and penalties under such laws.
There also is the threat of consumer class actions related to these laws and the overall protection of personal data. Even if we are not determined to have
violated these laws, government investigations into these issues typically require the expenditure of significant resources and generate negative publicity,
which could harm our reputation and our business.

Given the breadth and depth of changes in data protection obligations, preparing for and complying with these requirements is rigorous and time

intensive and requires significant resources and a review of our technologies, systems and practices, as well as those of any third-party collaborators,
service providers, contractors or consultants that process or transfer personal data collected in the European Union. The GDPR and other changes in laws or
regulations associated with the enhanced protection of certain types of sensitive data, such as healthcare data or other personal information from our
clinical trials, could require us to change our business practices and put in place additional compliance mechanisms, may interrupt or delay our
development, regulatory and commercialization activities and increase our cost of doing business, and could lead to government enforcement actions,
private litigation and significant fines and penalties against us and could have a material adverse effect on our business, financial condition or results of
operations.

Laws and regulations governing any international operations we may have in the future may preclude us from developing, manufacturing and selling
certain products outside of the United States and require us to develop and implement costly compliance programs.

As we expand our operations outside of the United States, we must dedicate additional resources to comply with numerous laws and regulations in

each jurisdiction in which we plan to operate. The Foreign Corrupt Practices Act, or FCPA, prohibits any U.S. individual or business from paying, offering,
authorizing payment or offering of anything of value, directly or indirectly, to any foreign official, political party or candidate for the purpose of
influencing any act or decision of the foreign entity in order to assist the individual or business in obtaining or retaining business. The FCPA also obligates
companies whose securities are listed in the United States to comply with certain accounting provisions requiring the company to maintain books and
records that accurately and fairly reflect all transactions of the corporation, including international subsidiaries, and to devise and maintain an adequate
system of internal accounting controls for international operations.

Compliance with the FCPA is expensive and difficult, particularly in countries in which corruption is a recognized problem. In addition, the FCPA
presents particular challenges in the pharmaceutical industry, because, in many countries, hospitals are operated by the government, and doctors and other
hospital employees are considered foreign officials. Certain payments to hospitals in connection with clinical trials and other work have been deemed to be
improper payments to government officials and have led to FCPA enforcement actions.

Various laws, regulations and executive orders also restrict the use and dissemination outside of the United States, or the sharing with certain non-

U.S. nationals, of information classified for national security purposes, as well as certain products and technical data relating to those products. As we
expand our presence outside of the United States, it will require us to dedicate additional resources to comply with these laws, and these laws may preclude
us from developing, manufacturing, or selling certain products and product candidates outside of the United States, which could limit our growth potential
and increase our development costs.

The failure to comply with laws governing international business practices may result in substantial civil and criminal penalties and suspension or
debarment from government contracting. The Securities and Exchange Commission, or SEC, also may suspend or bar issuers from trading securities on
U.S. exchanges for violations of the FCPA’s accounting provisions.

If we fail to comply with environmental, health and safety laws and regulations, we could become subject to fines or penalties or incur costs that could
harm our business.

We are subject to numerous environmental, health and safety laws and regulations, including those governing laboratory procedures and the
handling, use, storage, treatment and disposal of hazardous materials and wastes. From time to time and in the future, our operations may involve the use of
hazardous and flammable materials, including chemicals and biological materials, and may also produce hazardous waste products. Even if we contract
with third parties for the disposal of these materials and waste products, we cannot completely eliminate the risk of contamination or injury resulting from
these materials. In the event of contamination or injury resulting from the use or disposal of our hazardous materials, we could be held liable for any
resulting damages, and any liability could exceed our resources. We also could incur significant costs associated with civil or criminal fines and penalties
for failure to comply with such laws and regulations.

We maintain workers’ compensation insurance to cover us for costs and expenses we may incur due to injuries to our employees resulting from the
use of hazardous materials, but this insurance may not provide adequate coverage against potential liabilities. However, we do not maintain insurance for
environmental liability or toxic tort claims that may be asserted against us.

In addition, we may incur substantial costs in order to comply with current or future environmental, health and safety laws and regulations. Current

or future environmental laws and regulations may impair our research, development or production efforts. In addition, failure to comply with these laws
and regulations may result in substantial fines, penalties or other sanctions.

Our employees may engage in misconduct or other improper activities, including non-compliance with regulatory standards and requirements, which
could cause significant liability for us and harm our reputation.

We are exposed to the risk of employee fraud or other misconduct, including intentional failures to comply with FDA regulations or similar

regulations of comparable foreign regulatory authorities, provide accurate information to the FDA or comparable foreign regulatory authorities, comply
with manufacturing standards, comply with federal and state healthcare fraud and abuse laws and regulations and similar laws and regulations established
and enforced by comparable foreign regulatory authorities, report financial information or data accurately or disclose unauthorized activities to us.
Employee misconduct could also involve the improper use of information obtained in the course of clinical trials, which could result in regulatory sanctions
and serious harm to our reputation. This could include violations of HIPAA, other U.S. federal and state law, and requirements of non-U.S. jurisdictions,
including the European Union Data Protection Directive. It is not always possible to identify and deter employee misconduct, and the precautions we take
to detect and prevent this activity may not be effective in controlling unknown or unmanaged risks or losses or in protecting us from governmental
investigations or other actions or lawsuits stemming from a failure to be in compliance with such laws, standards, regulations, guidance or codes of
conduct. If any such actions are instituted against us, and we are not successful in defending ourselves or asserting our rights, those actions could have a
significant impact on our business and results of operations, including the imposition of significant fines or other sanctions.

Risks Related to Employee Matters and Managing Growth

Our future success depends on our ability to retain our executive team and to attract, retain and motivate qualified personnel.

We are highly dependent on the pharmaceutical research and development and business development expertise of our executive team, including

Cedric Francois, M.D., Ph.D., our President and Chief Executive Officer, and Pascal Deschatelets, Ph.D., our Chief Scientific Officer. The members of our
executive team are employed “at will,” meaning any of them may terminate his or her employment with us at any time with or without notice and for any
reason or no reason. In the future, we may be dependent on other members of our management, scientific and development team.

Our ability to compete in the biotechnology and pharmaceuticals industries depends upon our ability to attract and retain highly qualified

managerial, scientific and medical personnel. Our industry has experienced a high rate of turnover of management personnel in recent years. If we lose one
or more of our executive officers or other key employees, our ability to implement our business strategy successfully could be seriously harmed.
Furthermore, replacing executive officers or other key employees may be difficult and may take an extended period of time because of the limited number
of individuals in our industry with the breadth of skills and experience required to develop, gain marketing approval of and commercialize products
successfully. Competition to hire from this limited pool is intense, and we may be unable to hire, train, retain or motivate these additional key employees on
acceptable terms given the competition among numerous pharmaceutical and biotechnology companies for similar personnel. We also experience
competition for the hiring of scientific and clinical personnel from universities and research institutions.

We rely on consultants and advisors, including scientific and clinical advisors, to assist us in formulating our research and development and

commercialization strategy. Our consultants and advisors may be employed by other entities and may have commitments under consulting or advisory
contracts with those entities that may limit their availability to us. If we are unable to continue to attract and retain highly qualified personnel, our ability to
develop and commercialize our product candidates will be limited.

We expect to continue to expand our organization, and as a result, we may encounter difficulties in managing our growth, which could disrupt our
operations.

We continue to expect to experience significant growth in the number of our employees and the scope of our operations, particularly in the areas of

drug manufacturing, clinical, regulatory affairs and sales, marketing and distribution. During 2020, the number of our employees increased from 235 on
December 31, 2019 to 374 on December 31, 2020. We expect the number of employees to continue to increase significantly in 2021. Our principal office is
located in Massachusetts and we maintain additional offices in California, Australia and Switzerland. To manage these growth activities and separation of
offices, we must continue to

77

 
implement and improve our managerial, operational and financial systems and continue to recruit and train additional qualified personnel. Our management
may need to devote a significant amount of its attention to managing these growth activities. Due to our limited financial resources and the limited
experience of our management team in managing a company with such anticipated growth, we may not be able to effectively manage the expansion of our
operations, retain key employees, or identify, recruit and train additional qualified personnel. Our inability to manage the expansion of our operations
effectively may result in weaknesses in our infrastructure, give rise to operational mistakes, loss of business opportunities, loss of employees and reduced
productivity among remaining employees. Our expected growth could also require significant capital expenditures and may divert financial resources from
other projects, such as the development of additional product candidates. If we are unable to effectively manage our expected growth, our expenses may
increase more than expected, our ability to generate revenues could be reduced and we may not be able to implement our business strategy, including the
successful commercialization of our product candidates.

We temporarily closed our facilities in March 2020 in response to the COVID-19 pandemic.  We have since re-opened our physical facilities on a

limited basis, subject to compliance with strict safety guidelines, but most of our employees continue to work remotely. In the event of a renewal of shelter-
in-place orders or and mandated local travel restrictions, our employees conducting research and development activities may not be able to access our
facilities and our activities may be significantly limited or curtailed, possibly for an extended period of time. Furthermore, it is possible that over the long
term our operational efficiency may be decreased if our employees and third-party collaborators are unable to meet and work in the same physical location.

Our employees, independent contractors, consultants, collaborators and contract research organizations may engage in misconduct or other improper
activities, including non-compliance with regulatory standards and requirements, which could cause significant liability for us and harm our
reputation.

We are exposed to the risk that our employees, independent contractors, consultants, collaborators and contract research organizations may

engage in fraud or other misconduct, including intentional failures to comply with FDA regulations or similar regulations of comparable non-U.S.
regulatory authorities, to provide accurate information to the FDA or comparable non-U.S. regulatory authorities, to comply with manufacturing standards
we have established, to comply with federal and state healthcare fraud and abuse laws and regulations and similar laws and regulations established and
enforced by comparable non-U.S. regulatory authorities, to report financial information or data accurately or to disclose unauthorized activities to us. Such
misconduct could also involve the improper use of information obtained in the course of clinical trials, which could result in regulatory sanctions and
serious harm to our reputation. It is not always possible to identify and deter misconduct, and the precautions we take to detect and prevent this activity
may not be effective in controlling unknown or unmanaged risks or losses or in protecting us from governmental investigations or other actions or lawsuits
stemming from a failure to be in compliance with such laws, standards or regulations. These risks may be particularly acute given the rapid growth in the
size of our company. If any such actions are instituted against us, and we are not successful in defending ourselves or asserting our rights, those actions
could have a significant impact on our business and results of operations, including the imposition of significant criminal, civil and administrative sanctions
including monetary penalties, damages, fines, disgorgement, individual imprisonment, and exclusion from participation in government funded healthcare
programs, such as Medicare and Medicaid, additional reporting requirements and oversight if we become subject to a corporate integrity agreement or
similar agreement to resolve allegations of non-compliance with these laws, reputational harm, and we may be required to curtail or restructure our
operations.

We may engage in acquisitions that could disrupt our business, cause dilution to our stockholders or reduce our financial resources.

In the future, we may enter into transactions to acquire other businesses, products or technologies. Because we have not made any acquisitions to

date, our ability to do so successfully is unproven. If we do identify suitable candidates, we may not be able to make such acquisitions on favorable terms,
or at all. Any acquisitions we make may not strengthen our competitive position, and these transactions may be viewed negatively by customers or
investors. We may decide to incur debt in connection with an acquisition or issue our common stock or other equity securities to the stockholders of the
acquired company, which would reduce the percentage ownership of our existing stockholders. We could incur losses resulting from undiscovered
liabilities of the acquired business that are not covered by the indemnification we may obtain from the seller. In addition, we may not be able to
successfully integrate the acquired personnel, technologies and operations into our existing business in an effective, timely and non-disruptive manner.
Acquisitions may also divert management attention from day-to-day responsibilities, increase our expenses and reduce our cash available for operations
and other uses. We cannot predict the number, timing or size of future acquisitions or the effect that any such transactions might have on our operating
results.

Risks Related to Ownership of Our Common Stock

An active trading market for our common stock may not be sustainable. If an active trading market is not sustained, our ability to raise capital in the
future may be impaired.

78

Our shares began trading on the Nasdaq Global Select Market on November 9, 2017. Given the limited trading history of our common stock, there

is a risk that an active trading market for our shares may not be sustained, which could put downward pressure on the market price of our common stock
and thereby affect the ability of stockholders to sell their shares. An inactive trading market for our common stock may also impair our ability to raise
capital to continue to fund our operations by selling shares and impair our ability to acquire other companies or technologies by using our shares as
consideration.

The trading price of our common stock is highly volatile, which could result in substantial losses for our stockholders.

The trading price of our common stock has been, and is likely to continue to be, highly volatile and could be subject to wide fluctuations in response

to various factors, some of which are beyond our control. The stock market in general and the market for smaller pharmaceutical and biotechnology
companies in particular have experienced extreme volatility that has often been unrelated to the operating performance of particular companies. As a result
of this volatility, our stockholders may not be able to sell their common stock at or above the price they paid for their common stock. The market price for
our common stock may be influenced by many factors, including:

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

the timing and results of clinical trials of pegcetacoplan and any other product candidates;

regulatory developments with respect to pegcetacoplan, including with respect to our efforts to obtain approval with respect to our NDA and
MAA related to pegcetacoplan for the treatment of PNH;

the success of existing or new competitive products or technologies;

results of discussions with regulatory authorities and regulatory actions with respect to our product candidates or our competitors’ products
and product candidates;

the effect of the COVID-19 outbreak on the healthcare system and the economy generally and on our clinical trials and other operations
specifically;

announcements by us or our competitors of significant acquisitions, strategic partnerships, joint ventures, collaborations or capital
commitments;

commencement or termination of collaborations for our development programs;

failure or discontinuation of any of our product candidates or development programs;

results of clinical trials of product candidates of our competitors;

regulatory or legal developments in the United States and other countries;

developments or disputes concerning patent applications, issued patents or other proprietary rights;

the recruitment or departure of key personnel;

the level of expenses related to any of our product candidates or clinical development programs;

the results of our efforts to develop additional product candidates or products;

actual or anticipated changes in estimates as to financial results or development timelines;

announcement or expectation of additional financing efforts;

sales of our common stock by us, our insiders or other stockholders;

variations in our financial results or those of companies that are perceived to be similar to us;

short positions, hedging or other transactions in our securities in connection with our Convertible Notes;

changes in estimates or recommendations by securities analysts, if any, that cover our stock;

changes in the structure of healthcare payment systems;

market conditions in the pharmaceutical and biotechnology sectors;

general economic, industry and market conditions; and

the other factors described in this “Risk Factors” section.

We could be subject to securities class action litigation.

In the past, securities class action litigation has often been brought against a company following a decline in the market price of its securities. This

risk is especially relevant for us because pharmaceutical companies have experienced significant stock price

79

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
volatility in recent years. If we face such litigation, it could result in substantial costs and a diversion of management’s attention and our resources, which
could harm our business.

We have broad discretion in the use of our funds and may not use them effectively.

Our management will have broad discretion in the application of our cash, cash equivalents and marketable securities and could spend our funds in

ways that do not improve our results of operations or enhance the value of our common stock. The failure by our management to apply these funds
effectively could result in financial losses that could harm our business, cause the price of our common stock to decline and delay the development of our
product candidates. Pending their use, we may invest our funds in a manner that does not produce income or that loses value.

We incur increased costs as a result of operating as a public company, and our management is required to devote substantial time to compliance
initiatives and corporate governance practices.

As a public company, we incur significant legal, accounting and other expenses. The Sarbanes-Oxley Act of 2002, the Dodd-Frank Wall Street

Reform and Consumer Protection Act, the listing requirements of the Nasdaq Global Select Market and other applicable securities rules and regulations
impose various requirements on public companies, including establishment and maintenance of effective disclosure and financial controls and corporate
governance practices. Our management and other personnel devote and will need to continue to devote, a substantial amount of time to these compliance
initiatives. Moreover, these rules and regulations increase our legal and financial compliance costs and make some activities more time-consuming and
costly.

If we identify a material weakness in our internal control over financial reporting, it could have an adverse effect on our business and financial results
and our ability to meet our reporting obligations could be negatively affected, each of which could negatively affect the trading price of our common
stock.

A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable

possibility that a material misstatement of our annual or interim financial statements will not be prevented or detected on a timely basis. Accordingly, a
material weakness increases the risk that the financial information we report contains material errors.

We regularly review and update our internal controls, disclosure controls and procedures, and corporate governance policies. In addition, we are
required under the Sarbanes-Oxley Act of 2002 to report annually on our internal control over financial reporting. Our system of internal controls, however
well-designed and operated, is based in part on certain assumptions and includes elements that rely on information from third parties. Our system can
provide only reasonable, not absolute, assurances that the objectives of the system are met. If we, or our independent registered public accounting firm,
determine that our internal controls over financial reporting are not effective, or we discover areas that need improvement in the future, these shortcomings
could have an adverse effect on our business and financial results, and the price of our common stock could be negatively affected.

If we cannot conclude that we have effective internal control over our financial reporting, or if our independent registered public accounting firm

is unable to provide an unqualified opinion regarding the effectiveness of our internal control over financial reporting, investors could lose confidence in
the reliability of our financial statements, which could lead to a decline in our stock price. Failure to comply with reporting requirements could also subject
us to sanctions and/or investigations by the SEC, The Nasdaq Stock Market or other regulatory authorities.

A sale of a substantial number of shares of our common stock could cause the market price of our common stock to decline significantly, even if our
business is doing well.

Sales of a substantial number of shares of our common stock in the public market could occur at any time. These sales, or the perception in the

market that the holders of a large number of shares of common stock intend to sell shares, could reduce the market price of our common stock.

We have registered all shares of common stock that we may issue under our equity compensation plans. As of December 31, 2020, we had options
to purchase an aggregate of 11,735,783 shares of our common stock outstanding, of which options to purchase 6,061,850 shares were vested and 502,373
outstanding unvested restricted stock units that upon vesting would result in the issuance of 502,373 shares of our common stock. These shares can be
freely sold in the public market upon issuance, subject to volume limitations applicable to affiliates. Moreover, holders of an aggregate of 11,098,982
shares of our common stock have rights, subject to conditions, to require us to file registration statements covering their shares or to include their shares in
registration statements that we may file for ourselves or other stockholders. If these additional shares are sold, or if it is perceived that they will be sold, in
the public market, the trading price of our common stock could decline.

80

Changes in tax laws or in their interpretation could adversely affect our business and financial condition.

Recent changes in tax law could adversely affect our business or financial condition. On December 22, 2017, the U.S. government enacted
legislation, commonly referred to as the Tax Cuts and Jobs Act, or the TCJA, that significantly revised the Internal Revenue Code of 1986, as amended, or
the Code. The TCJA, among other things, contained significant changes to corporate taxation, including reduction of the corporate tax rate from a top
marginal rate of 35% to a flat rate of 21%, limitation of the tax deduction for interest expense to 30% of adjusted earnings (except for certain small
businesses), limitation of the deduction for net operating losses to 80% of current year taxable income and elimination of net operating loss carrybacks for
losses arising in taxable years ending after December 31, 2017 (though any such net operating losses may be carried forward indefinitely), one time
taxation of offshore earnings at reduced rates regardless of whether they are repatriated, elimination of U.S. tax on foreign earnings (subject to certain
important exceptions), immediate deductions for certain new investments instead of deductions for depreciation expense over time, and modifying or
repealing many business deductions and credits.

As part of Congress’ response to the COVID-19 pandemic, the Families First Coronavirus Response Act, or FFCR Act, was enacted on March 18,
2020, and the Coronavirus Aid, Relief, and Economic Security Act, or CARES Act, was enacted on March 27, 2020.  COVID relief provisions were also
included in the Consolidated Appropriations Act, 2021, or CAA, which was enacted on December 27, 2020.  The FFCR Act, the CARES Act, and the CAA
contain numerous tax provisions.  In particular, the CARES Act retroactively and temporarily (for taxable years beginning before January 1, 2021)
suspends application of the 80%-of-income limitation on the use of net operating losses, which was enacted as part of the TCJA.  It also provides that net
operating losses arising in any taxable year beginning after December 31, 2017, and before January 1, 2021, are generally eligible to be carried back up to
five years.  The CARES Act also temporarily (for taxable years beginning in 2019 or 2020) relaxes the limitation on the tax deductibility of net interest
expense by increasing the limitation from 30% to 50% of adjusted taxable income.

Regulatory guidance under the TCJA, the FFCR Act, the CARES Act, and the CAA is and continues to be forthcoming, and such guidance could

ultimately increase or lessen the impact of these laws on our business and financial condition.  Congress may enact additional legislation in connection with
the COVID-19 pandemic, some of which could have an impact on our company.  In addition, it is uncertain if and to what extent various states will
conform to the TCJA, the FFCR Act, the CARES Act, or the CAA.  

We might not be able to utilize a significant portion of our net operating loss carryforwards and research and development tax credit carryforwards.

As of December 31, 2020, we had both federal and state net operating loss carryforwards of $358.2 million and $405.0 million, respectively, and

federal and state research and development tax credit carryforwards of $34.2 million and $6.5 million, respectively. Federal net operating loss carryforward
generated post-2017 in the amount of $276.9 million may be carried forward indefinitely.  The remaining net operating loss and research and development
tax credit carryforwards will begin to expire in 2025. These net operating loss and tax credit carryforwards could expire unused and be unavailable to offset
future income tax liabilities. Under the TCJA, as modified by the CARES act, federal net operating losses incurred in 2018 and in future years may be
carried forward indefinitely, but the deductibility of such federal net operating losses in 2021 and future years is limited. Certain states have also enacted
temporary suspension or limitation of the utilization of net operating loss carryforwards. In addition, under Section 382 of the Code, and corresponding
provisions of state law, if a corporation undergoes an “ownership change,” which is generally defined as a greater than 50% change, by value, in its equity
ownership over a three-year period, the corporation’s ability to use its pre-change net operating loss carryforwards and other pre-change tax attributes to
offset its post-change income may be limited. We experienced a Section 382 ownership change in September 2015, which imposes annual limitations on
our use of pre-change net operating loss carryforwards and other pre-change tax attributes. In addition, we may experience ownership changes in the future
as a result of subsequent shifts in our stock ownership, some of which may be outside of our control. We have determined that our research and
development credit carryforwards are also limited. These limitations upon our historical net operating loss and tax credit carryforwards may harm our
future operating results by effectively increasing our future tax obligations. Refer to Note 14, “Income Taxes,” of our Financial Statements for additional
information related to our accounting for income taxes.

Taxing authorities could challenge our historical and future tax positions or our allocation of taxable income among our subsidiaries, and tax laws to
which we are subject could change in a manner adverse to us.

We operate through various subsidiaries in a number of countries throughout the world. Consequently, we are subject to tax laws, treaties, and

regulations in the countries in which we operate, and these laws and treaties are subject to interpretation. We have taken, and will continue to take, tax
positions based on our interpretation of such tax laws. Our transfer pricing arrangements are not generally binding on applicable tax authorities. The price
charged for products, services, or the royalty rates and other amounts paid for intellectual property rights, could be challenged by the various tax
authorities, resulting in additional tax liability, interest, and/or penalties. There can be no assurance that a taxing authority will not have a different
interpretation of applicable law and assess us with additional taxes. If we are assessed with additional taxes, this may result in a material adverse effect on
our results of operations and/or financial condition.

81

Any changes to existing accounting pronouncements or taxation rules or practices may cause adverse fluctuations in our reported results of operations
or affect how we conduct our business.

A change in accounting pronouncements or taxation rules or practices can have a significant effect on our reported results and may affect our

reporting of transactions completed before the change is effective. New accounting pronouncements, taxation rules and varying interpretations of
accounting pronouncements or taxation rules have occurred in the past and may occur in the future. The change to existing rules, future changes, if any, or
the need for us to modify a current tax or accounting position may adversely affect our reported financial results or the way we conduct our business.

We do not anticipate paying any cash dividends on our capital stock in the foreseeable future. Accordingly, stockholders must rely on capital
appreciation, if any, for any return on their investment.

We have never declared nor paid cash dividends on our capital stock. We currently plan to retain all of our future earnings, if any, to finance the
operation, development and growth of our business. In addition, the terms of our development funding agreement with SFJ, precludes us from paying
dividends, and any future debt or credit agreements may also preclude us from paying dividends. As a result, capital appreciation, if any, of our common
stock will be our stockholders’ sole source of gain for the foreseeable future.

Concentration of ownership of our common stock among our executive officers and directors, entities associated with our executive officers and
directors and our largest stockholders may allow these stockholders to significantly influence matters submitted to our stockholders for approval, as
well as our management and affairs.

As of February 22, 2021, our executive officers and directors, and entities associated or affiliated with our executive officers and directors, in the

aggregate, beneficially owned shares representing approximately 24.5% of our outstanding common stock, including our largest stockholder, Morningside
Venture Investments, Ltd., which beneficially owned approximately 15.6% of our outstanding common stock. As a result, if these stockholders were to
choose to act together, they may have the ability to significantly influence all matters submitted to our stockholders for approval, as well as our
management and affairs. For example, these persons, if they choose to act together, could substantially influence the election of directors and approval of
any merger, consolidation or sale of all or substantially all of our assets. This concentration of ownership may:

•

•

•

delay, defer or prevent a change in control;

entrench our management or the board of directors; or

impede a merger, consolidation, takeover or other business combination involving us that other stockholders may desire.

Some of these persons or entities may have interests different than those of our other investors. For example, because many of these stockholders

purchased their shares at prices substantially below the price at which other investors purchased shares and have held their shares for a longer period, they
may be more interested in selling our company to an acquirer than other investors or they may want us to pursue strategies that deviate from the interests of
other stockholders.

Provisions in our corporate charter documents and under Delaware law may prevent or frustrate attempts by our stockholders to change our
management or hinder efforts to acquire a controlling interest in us.

Provisions in our corporate charter and our bylaws may discourage, delay or prevent a merger, acquisition or other change in control of us that

stockholders may consider favorable, including transactions in which our stockholders might otherwise receive a premium for their shares. These
provisions could also limit the price that investors might be willing to pay in the future for shares of our common stock, thereby depressing the market price
of our common stock. In addition, because our board of directors is responsible for appointing the members of our management team, these provisions may
frustrate or prevent any attempts by our stockholders to replace or remove our current management by making it more difficult for stockholders to replace
members of our board of directors. Among other things, these provisions:

•

•

•

•

•

•

establish a classified board of directors such that all members of the board are not elected at one time;

allow the authorized number of our directors to be changed only by resolution of our board of directors;

limit the manner in which stockholders can remove directors from the board;

establish advance notice requirements for nominations for election to the board of directors or for proposing matters that can be acted on at
stockholder meetings;

require that stockholder actions must be effected at a duly called stockholder meeting and prohibit actions by our stockholders by written
consent;

limit who may call a special meeting of stockholders;

82

 
 
 
 
 
 
 
 
 
•

•

authorize our board of directors to issue preferred stock without stockholder approval, which could be used to institute a “poison pill” that
would work to dilute the stock ownership of a potential hostile acquirer, effectively preventing acquisitions that have not been approved by
our board of directors; and

require the approval of the holders of at least 75% of the votes that all our stockholders would be entitled to cast to amend or repeal certain
provisions of our charter or bylaws.

Moreover, because we are incorporated in Delaware, we are governed by the provisions of Section 203 of the General Corporation Law of the State
of Delaware, which prohibits a person who owns in excess of 15% of our outstanding voting stock from merging or combining with us for a period of three
years after the date of the transaction in which the person acquired in excess of 15% of our outstanding voting stock, unless the merger or combination is
approved in a prescribed manner. This could discourage, delay or prevent someone from acquiring us or merging with us, whether or not it is desired by, or
beneficial to, our stockholders. This could also have the effect of discouraging others from making tender offers for our common stock, including
transactions that may be in the best interests of our stockholders. These provisions may also prevent changes in our management or limit the price that
investors are willing to pay for our stock.

If securities or industry analysts do not publish research or publish inaccurate or unfavorable research about our business, our share price and trading
volume could decline.

The trading market for our common stock will likely depend in part on the research and reports that securities or industry analysts publish about us

or our business. We do not have any control over these analysts. There can be no assurance that analysts will continue to cover us or provide favorable
coverage. Securities or industry analysts may elect not to provide research coverage of our common stock, and such lack of research coverage may
negatively impact the market price of our common stock. In the event we do have analyst coverage, if one or more analysts downgrade our stock or change
their opinion of our stock, our share price would likely decline. In addition, if one or more analysts cease coverage of our company or fail to regularly
publish reports on us, we could lose visibility in the financial markets, which could cause our share price or trading volume to decline.

Our restated certificate of incorporation designates the state courts in the State of Delaware or, if no state court located within the State of Delaware
has jurisdiction, the federal court for the District of Delaware, as the sole and exclusive forum for certain types of actions and proceedings that may be
initiated by our stockholders, which could discourage lawsuits against our company and our directors, officers and employees.

Our restated certificate of incorporation provides that, unless we consent in writing to the selection of an alternative forum, the Court of Chancery of

the State of Delaware (or, if the Court of Chancery does not have jurisdiction, the federal district court for the District of Delaware) will be the sole and
exclusive forum for any derivative action or proceeding brought on our behalf, any action asserting a claim of breach of a fiduciary duty owed by any of
our directors, officers or employees to our company or our stockholders, any action asserting a claim against us arising pursuant to any provision of the
General Corporation Law of the State of Delaware or our certificate of incorporation or bylaws, or any action asserting a claim against us governed by the
internal affairs doctrine. This exclusive forum provision will not apply to actions arising under the Securities Act of 1933, as amended, or the Securities
Exchange Act of 1934, as amended. This exclusive forum provision may limit the ability of our stockholders to bring a claim in a judicial forum that such
stockholders find favorable for disputes with us or our directors, officers or employees, which may discourage such lawsuits against us and our directors,
officers and employees.

Market Information

Our common stock has been listed on the Nasdaq Global Select Market under the symbol “APLS” since November 9, 2017. Prior to that date,

there was no public trading market for our common stock.  

 Holders of Record

As of February 22, 2021, we had 22 holders of record of our common stock. The actual number of stockholders is greater than this number of

record holders, and includes stockholders who are beneficial owners, but whose shares are held in street name by brokers and other nominees. This number
of holders of record also does not include stockholders whose shares may be held in trust by other entities.

Dividend Policy

We have never declared or paid cash dividends on our capital stock. In addition, our development agreement with SFJ contains restrictive

covenants that prohibit us, subject to certain exceptions, from paying dividends on our common stock, and future debt securities or other financing
arrangements could contain similar or more restrictive negative covenants. We intend to retain all available funds and any future earnings, if any, to fund

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

You should read the following discussion and analysis of our financial condition and results of operations together with our consolidated financial
statements and related notes included elsewhere in this Annual Report on Form 10-K. This discussion and other parts of this Annual Report on Form 10-K
contain forward-looking statements that involve risk and uncertainties, such as statements of our plans, objectives, expectations and intentions. As a result
of many factors, including those factors set forth in the “Risk Factors” section of this Annual Report on Form 10-K, our actual results could differ
materially from the results described in or implied by the forward-looking statements contained in the following discussion and analysis.

Overview

We are a clinical-stage biopharmaceutical company focused on the development of novel therapeutic compounds to treat disease through the

inhibition of the complement system, which is an integral component of the immune system, at the level of C3, the central protein in the complement
cascade. We believe that this approach can result in broad inhibition of the principal pathways of the complement system and has the potential to effectively
control a broad array of complement-dependent autoimmune and inflammatory diseases.

We have the most advanced clinical programs targeting C3 with Phase 3 clinical trials of our lead product candidate, pegcetacoplan, in multiple

indications. We believe that pegcetacoplan has the potential to be a best-in-class treatment that may address the limitations of existing treatment options or
provide a treatment option where there currently is none. Pegcetacoplan has already shown activity that we believe is clinically meaningful in clinical trials
for several distinct medical conditions, including geographic atrophy in age-related macular degeneration, or GA; paroxysmal nocturnal hemoglobinuria, or
PNH; cold agglutinin disease, or CAD; and C3 glomerulopathy, or C3G. We are developing pegcetacoplan and other product candidates, including APL-9,
targeting C3 through various routes of administration and plan to conduct clinical trials of these compounds in additional complement-dependent
indications.

In October 2020, we entered into a collaboration and license agreement, or the collaboration agreement, with Swedish Orphan Biovitrum AB (Publ),

or Sobi.  Under the collaboration agreement, we agreed to co-develop pegcetacoplan for systemic indications, including PNH, CAD and hematopoietic
stem cell transplantation-associated thrombotic microangiopathy, or HSCT-TMA, in hematology; C3G and immune complex membranoproliferative
glomerulonephritis, or IC-MPGN in nephrology; and amyotrophic lateral sclerosis, or ALS in neurology.  Sobi has exclusive ex-U.S. commercialization
rights for systemic pegcetacoplan.  We retain commercialization rights for systemic pegcetacoplan in the United States and worldwide commercial rights
for ophthalmological pegcetacoplan, which includes our GA program in addition to worldwide commercialization rights for APL-9 and other novel
compounds targeting C3.

GA. We initiated a Phase 3 clinical program consisting of two Phase 3 clinical trials evaluating pegcetacoplan in patients with GA in September

2018. We refer to these trials as the DERBY and OAKS trials. Both trials are fully enrolled and we expect to announce top-line data from these trials in the
third quarter of 2021.  In our Phase 2 clinical trial of pegcetacoplan in patients with GA, treatment with pegcetacoplan resulted in a significant reduction in
the rate of GA lesion growth over 12 months.  Additionally, data released in October 2020 from a post hoc analysis of seven patients in our Phase 1b trial of
pegcetacoplan in patients with advanced GA and low vision demonstrated a trend in reduced lesion growth in eyes treated with pegcetacoplan versus
untreated fellow eyes after 18 months of treatment.

Systemic Pegcetacoplan.  We are developing pegcetacoplan for systemic administration in several indications, including PNH, C3G, IC-MPGN,

ALS, CAD and HSCT-TMA.

PNH. In June 2018, we initiated a Phase 3 clinical trial evaluating pegcetacoplan in 80 patients with PNH who exhibited signs of moderate to severe

anemia, specifically with an inclusion criterion of hemoglobin level of less than 10.5 g/dL, while being treated with eculizumab, an approved therapy for
PNH that is marketed as Soliris. We refer to this trial as the PEGASUS trial.

In January 2020, we announced top-line data from the PEGASUS trial that showed that pegcetacoplan met the trial’s primary efficacy endpoint,
demonstrating superiority to eculizumab, with a statistically significant improvement in adjusted means of 3.8 g/dL of hemoglobin at week 16 (p < 0.0001),
and promising results in key secondary endpoints. Additional data from the PEGASUS trial presented in June 2020 and December 2020 demonstrated
increased hemoglobin levels, reduced transfusion requirements and improved key markers of hemolysis across the patient population, both in patients with
high transfusion requirements and in patients with low or no transfusion requirements, which improvements were sustained through 48 weeks of
treatment.  In the PEGASUS trial, the safety profile of pegcetacoplan was comparable to that of eculizumab.  

In September 2019, we initiated a second Phase 3 clinical trial in patients with PNH who have not been treated with eculizumab within three months
before entering the trial. This trial is fully enrolled and we intend to present top-line data in the second quarter of 2021. We refer to this trial as the PRINCE
trial.

89

 
We submitted an NDA to the FDA, and an MAA to the EMA, for pegcetacoplan for the treatment of PNH in September 2020. The FDA accepted

the NDA and set the Prescription Drug User Fee Act, or PDUFA, target action date for May 14, 2021.  The EMA validated the MAA in October 2020, with
the potential for a European Commission decision on the MAA in the second half of 2021.  

C3G/IC-MPGN. We have initiated and will continue to lead our registrational program in C3G / IC-MPGN.  We initiated the Phase 2 NOBLE trial

in up to 12 patients with post-kidney transplant recurrence of C3G or IC-MPGN in October 2020. We expect to dose the first patient in the NOBLE trial in
the first half of 2021. We also plan to begin a Phase 3 clinical trial in patients with native kidney or post-transplant recurrence of C3G or IC-MPGN, having
reduction of proteinuria as its primary endpoint, in the second half of 2021.

ALS.  We have initiated a randomized, placebo-controlled Phase 2 clinical trial of pegcetacoplan in approximately 200 adults with sporadic
ALS.  We refer to this trial as the MERIDIAN trial.  We treated the first patient in MERIDIAN in November 2020 and expect to complete enrollment in
MERIDIAN in the second half of 2021.

CAD and HSCT-TMA. Sobi will lead development activities for a Phase 3 clinical trial in CAD and a Phase 2 clinical trial in HSCT-TMA, both
planned to begin in 2021.  In our Phase 2 clinical trial of pegcetacoplan in patients with CAD, patients achieved increased hemoglobin levels, reduced
reticulocytes and bilirubin levels, and reduced LDH levels compared to baseline.

Pipeline.  We are developing pegcetacoplan and other product candidates, including APL-9, targeting C3 through various routes of

administration.  We plan to conduct clinical trials of these compounds in additional complement-dependent indications. APL-9 is a C3 modulator designed
to be intravenously administered for acute use.  In May 2020 we initiated a Phase 1/2 randomized, placebo-controlled clinical trial for APL-9 in 66 patients
with respiratory failure including acute respiratory distress syndrome (ARDS) secondary to COVID-19. We expect to report results from this trial in the
second quarter of 2021. We are also developing APL-9 for the prevention of complement immune system activation coincident with adeno-associated virus,
or AAV, vector administration for gene therapies and other indications.  We plan to advance three new product candidates into clinical development by the
end of 2022.

Since our commencement of operations in May 2010, we have devoted substantially all of our resources to developing our proprietary technology,

developing product candidates, undertaking preclinical studies and conducting clinical trials for pegcetacoplan, building our intellectual property portfolio,
organizing and staffing our company, business planning, raising capital, preparing for the commercial launch of our products and providing general and
administrative support for these operations.

To date, we have financed our operations primarily through $772.1 million in net proceeds from public offerings of our common stock, including

our initial public offering, or IPO, $535.8 million in net proceeds from the private offerings of Convertible Notes, a $250.0 million upfront payment and a
$25.0 million as a development reimbursement payment from Sobi each pursuant to the Sobi collaboration agreement, $112.6 million in proceeds from the
private placement of shares of our convertible preferred stock prior to our IPO, $140.0 million under the SFJ agreement, $20.0 million in proceeds from
borrowings under a term loan facility with Silicon Valley Bank, and $7.0 million in proceeds from our issuance and sale of a promissory note. We have
repaid the term loan facility and the promissory note in full, and we exchanged $126.1 million of aggregate principal amount of 2019 Convertible Notes for
shares of our common stock in January 2021.

We have not generated any revenue from product sales. We have incurred significant annual net operating losses in each year since our inception
and expect to continue to incur net operating losses for the foreseeable future. Our net losses were $344.9 million, $304.7 million and $127.5 million for
the years ended December 31, 2020, 2019 and 2018, respectively. As of December 31, 2020, we had an accumulated deficit of $926.3 million. We expect to
continue to incur significant expenses and increasing operating losses for the next several years. Our net losses may fluctuate significantly from quarter to
quarter and year to year. We anticipate that our expenses will increase significantly if and as we continue to develop and conduct our ongoing and planned
clinical trials of pegcetacoplan and APL-9; initiate and continue research and preclinical and clinical development efforts for any future product candidates;
seek to identify and develop additional product candidates for complement-dependent diseases; seek regulatory and marketing approvals for our product
candidates that successfully complete clinical trials, if any; establish sales, marketing, distribution and other commercial infrastructure to commercialize
any products for which we may obtain marketing approval; require the manufacture of larger quantities of product candidates for clinical development and,
potentially, commercialization; maintain, expand and protect our intellectual property portfolio; hire and retain additional personnel, such as clinical,
quality control and scientific personnel; add operational, financial and management information systems and personnel, including personnel to support our
product development and help us comply with our obligations as a public company; and add equipment and physical infrastructure to support our research
and development programs.

As of December 31, 2020, we had cash, cash equivalents and marketable securities of $877.6 million. We believe that our cash and cash equivalents

and marketable securities as of December 31, 2020, will be sufficient to enable us to fund our current operations at least into the second half of 2022. We
have based this estimate on assumptions that may prove to be wrong, and we could exhaust our available capital resources sooner than we expect. See
“Liquidity and Capital Resources.”

90

We temporarily closed our facilities in March 2020 in respect to the COVID-19 pandemic. We have since reopened our facilities on a limited basis,
subject to compliance with strict safety guidelines, but most of our employees continue to work remotely. We do not believe that the COVID-19 pandemic
has had a significant impact upon our operations, including our ongoing clinical trials and the manufacture and supply of our product candidates.

SFJ Agreement

On February 28, 2019, we entered into a development funding agreement, which we refer to as the SFJ agreement, with SFJ Pharmaceuticals Group,

or SFJ, under which SFJ agreed to provide funding to us to support the development of pegcetacoplan for the treatment of patients with PNH. Pursuant to
the agreement, SFJ paid us $60.0 million following the signing of the agreement and agreed to pay us up to an additional $60.0 million in the aggregate in
three equal installments upon the achievement of specified development milestones with respect to our Phase 3 program for pegcetacoplan in PNH and
subject to our having cash resources at the time sufficient to fund at least 10 months of our operations.

On June 7, 2019, we amended the SFJ agreement, which we refer to as the SFJ amendment. Under the SFJ amendment, SFJ agreed to make an

additional $20.0 million funding payment to us to support the development of pegcetacoplan for the treatment of patients with PNH.

On June 27, 2019, we received $40.0 million from SFJ, consisting of $20.0 million as the first installment of the additional $60.0 million upon the

achievement of a milestone and the $20.0 million payable under the SFJ amendment.

In September 2019, we received $20.0 million from SFJ, as the second installment of the additional $60.0 million due to the achievement of a
milestone and in January 2020 received the remaining $20.0 million installment of the additional $60.0 million upon the announcement of the results of the
PEGASUS phase 3 trial.

Convertible Notes

In September 2019, we issued and sold $220.0 million aggregate principal amount of 3.5% convertible senior notes due 2026, or the 2019
Convertible Notes, in a private offering. The net proceeds from the sale of the 2019 Convertible Notes were approximately $212.9 million after deducting
the initial purchasers’ discounts and commissions and estimated offering expenses payable. We used $28.4 million of the net proceeds from the offering to
pay the cost of the capped call transactions in September 2019 described below.

In May 2020, we issued and sold an additional $300.0 million aggregate principal amount of 3.5% convertible senior notes due 2026, or the 2020

Convertible Notes, in a private offering. The aggregate purchase price of the 2020 Convertible Notes was $328.9 million, which amount included accrued
interest from March 15, 2020 to, but not including, May 12, 2020. The net proceeds from the sale of the 2020 Convertible Notes were approximately
$322.9 million after deducting the initial purchasers’ discounts and commissions and offering expenses payable by us. We used $43.1 million of the net
proceeds from the offering to pay the cost of the capped call transactions in May 2020 described below. The 2020 Convertible Notes were issued as
additional notes under the Indenture and form a single series with, and have the same terms as, the 2019 Convertible Notes, but have a different issue date,
issue price, CUSIP number and different restrictions on transfer. We refer to the 2019 Convertible Notes and the 2020 Convertible Notes together as the
Convertible Notes.

The Convertible Notes are convertible into shares of our common stock at an initial conversion rate of 25.3405 shares per $1,000 principal amount
of notes (equivalent to an initial conversion price of approximately $39.46 per share of common stock). The conversion rate is subject to customary anti-
dilution adjustments. In addition, following certain events that occur prior to the maturity date or if we deliver a notice of redemption, we will increase the
conversion rate for a holder who elects to convert its Convertible Notes in connection with such corporate event or a notice of redemption, as the case may
be, in certain circumstances as provided in the indenture governing the Convertible Notes, or the Indenture.

Prior to March 15, 2026, the Convertible Notes are convertible only upon the occurrence of certain events. On or after March 15, 2026 until the

close of business on the second scheduled trading day immediately preceding the maturity date of the Convertible Notes, holders may convert the
Convertible Notes at any time. Upon conversion of the Convertible Notes, we will pay or deliver, as the case may be, cash, shares of our common stock or
a combination of cash and shares of common stock, at our election.

Prior to September 20, 2023, we may not redeem the Convertible Notes. We may redeem for cash all or a portion of the Convertible Notes, at our

option, on or after September 20, 2023 if the last reported sale price of our common stock has been at least 130% of the conversion price then in effect for
at least 20 trading days (whether or not consecutive), including the trading day immediately preceding the date on which we provide a notice of
redemption, during any 30 consecutive trading day period ending on, and including, the trading day immediately preceding the date on which we provide
notice of redemption. The redemption price will be equal to 100% of the principal amount of the Convertible Notes to be redeemed, plus accrued and
unpaid interest to, but excluding, the redemption date.

91

If we undergo a “fundamental change,” as defined in the Indenture, prior to maturity, subject to certain conditions, holders may require us to

repurchase for cash all or any portion of their Convertible Notes at a fundamental change repurchase price equal to 100% of the principal amount of the
Convertible Notes to be repurchased, plus any accrued and unpaid interest to, but excluding, the fundamental change repurchase date.

The Indenture contains customary terms and covenants, including that upon certain events of default occurring and continuing, either the Trustee or
the holders of at least 25% in principal amount of the outstanding Convertible Notes may declare 100% of the principal of, and accrued and unpaid interest,
if any, on, all the Convertible Notes to be due and payable.

Subsequent to year end, on January 6, 2021, we entered into separate, privately negotiated exchange agreements with certain holders of our 2019

Convertible Notes.  Under the terms of these exchange agreements, the holders exchanged approximately $126.1 million in aggregate principal amount of
2019 Convertible Notes held by them for an aggregate of 3,906,869 shares of our common stock. The exchange transactions closed in January 2021.

Capped Call Transactions

In September 2019 and May 2020, concurrently with the pricing of the 2019 Convertible Notes and 2020 Convertible Notes, respectively, we

entered into capped call transactions with two counterparties. The capped call transactions are expected generally to reduce the potential dilution to our
common stock upon any conversion of Convertible Notes and/or offset any cash payments we are required to make in excess of the principal amount of
converted Convertible Notes, as the case may be, in the event that the market price per share of our common stock, as measured under the terms of the
capped call transactions, is greater than the strike price of the capped call transactions, which is initially $39.4625, the conversion price of the Convertible
Notes, and is subject to anti-dilution adjustments substantially similar to those applicable to the conversion rate of such Convertible Notes. If, however, the
market price per share of our common stock, as measured under the terms of the capped call transactions, exceeds the cap price of the capped call
transactions, there would nevertheless be dilution and/or there would not be an offset of such potential cash payments, in each case, to the extent that such
market price exceeds the cap price of the capped call transactions.

Collaboration Agreement with Sobi

On October 27, 2020, we entered into the collaboration agreement with Sobi, concerning the development and commercialization of pegcetacoplan

and specified other structurally and functionally similar compstatin analogues or derivatives for use systemically or for local non-ophthalmological
administration, collectively referred to as the licensed products. See “Business—Collaboration and License Agreement with Sobi” for a description of the
key terms of our collaboration agreement with Sobi. We granted Sobi an exclusive (subject to certain rights retained by us), sublicensable license of certain
patent rights and know-how to develop and commercialize licensed products in all countries outside of the United States. We retained the right to
commercialize licensed products in the United States, and, subject to specified limitations, to develop licensed products worldwide for commercialization
in the United States. Under the agreement, Sobi made an upfront payment of $250.0 million in November 2020, and agreed to pay up to an aggregate of
$915.0 million upon the achievement of specified one-time regulatory and commercial milestone events, and to reimburse us for up to $80.0 million in
development costs. In January 2021 we received a $25.0 million development reimbursement payment from Sobi.  We are also entitled to receive tiered,
double-digit royalties (ranging from high teens to high twenties) on sales of licensed products outside of the United States, subject to customary deductions
and third-party payment obligations, until the latest to occur of:  (i) expiration of the last-to-expire of specified licensed patent rights; (ii) expiration of
regulatory exclusivity; and (iii) ten (10) years after the first commercial sale of the applicable licensed product, in each case on a licensed product-by-
licensed product and country-by-country basis. We remain responsible for our license fee obligations (including royalty obligations) to the University of
Pennsylvania and for our payment obligations to SFJ Pharmaceuticals.

Financial Operations Overview

Revenue 

We have not generated any revenue from product sales.  If we are able to obtain regulatory approval for pegcetacoplan for the treatment of PNH in

the United States, we will expect to generate revenue from the sale of products within the next twelve months.  

Licensing and Collaboration Revenue

We enter into licensing agreements from time to time in which we receive upfront payments, milestone payments and royalties. In 2020 we entered

into a collaboration agreement with Sobi for the development and commercialization of systemic pegcetacoplan, described below, and two license
agreements with third parties to use APL-9 in certain research projects.

We analyze our license and collaboration arrangements pursuant to FASB ASC Topic 808, Collaborative Arrangement Guidance and Considerations
to assess whether such arrangements, or transactions between arrangement participants, involve joint operating activities performed by parties that are both
active participants in the activities and exposed to significant risks and rewards dependent on the commercial success of such activities or are more akin to
a vendor-customer relationship. In making this evaluation, we consider whether the activities of the collaboration are considered to be distinct and deemed
to be within the scope of the collaborative arrangement guidance and those that are more reflective of a vendor-customer relationship and, therefore, within
the scope of the revenue with contracts with customers guidance. This assessment is performed throughout the life of the arrangement based on changes in
the responsibilities of all parties in the arrangement.

For elements of collaboration arrangements that are not accounted for pursuant to the revenue from contracts with customers guidance, an

appropriate recognition method is determined and applied consistently, generally by analogy to the revenue from contracts with customers guidance.
Amounts related to transactions with a counterparty in a collaborative arrangement that is not a customer are presented as collaboration revenue and on a
separate line item from revenue recognized from contracts with customers, if any, in our consolidated statements of operations.

Revenue is recognized when a customer obtains control of promised goods or services, in an amount that reflects the consideration which the entity

expects to receive in exchange for those goods or services. To determine revenue recognition for arrangements that an entity determines are within the
scope of ASC 606, Revenue from Contracts with Customers (“ASC 606”), the Company performs the following five steps: (i) identify the contract(s) with
a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the
performance obligations in the contract; and (v) recognize revenue when (or as) the entity satisfies a performance obligation. The Company only applies
the five-step model to contracts when it is probable that the entity will collect the consideration it is entitled to in exchange for the goods or services it
transfers to the customer. At contract inception, once the contract is determined to be within the scope of ASC 606, the Company assesses the goods or
services promised within each contract, determines those that are performance obligations and assesses whether each promised good or service is distinct.
The Company then recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) the
performance obligation is satisfied.

Pursuant to ASC 606, we recorded the $250.0 million non-refundable upfront payment in revenue as the payment was associated with the transfer of

the good or services in the form of the license to Sobi.  The $80.0 million reimbursement for research and development activities does not constitute a
customer/vendor relationship and thus is not in the scope of ASC 606.  As ASC 808 does not include recognition guidance, we established an accounting
policy to recognize the payments under the reimbursement as a receivable on the balance sheet in an amount that is probable to be reimbursed based upon
expense incurred by us, with a contra-research and development expense recognized in the statement of operations.

Under the Sobi collaboration agreement, for the year ended December 31, 2020, we recognized $250.0 million of licensing revenue for the upfront

payment in the consolidated statement of operations.  For the year ended December 31, 2020, we also recognized in the consolidated statement of
operations $43.0 million of contra research and development expense relative to the probable amount to be reimbursed under the $80.0 million for research
and development.  We recorded a corresponding receivable of $43.0 million on the consolidated balance sheet, with $25.0 million and $18.0 million in
current and long-term assets, respectively, as of December 31, 2020.

Research and Development Expenses 

Research and development expenses consist primarily of costs incurred for our research activities, including our drug discovery efforts, and the

development of our product candidates, which include:

•

•

•

•

employee-related expenses including salaries, bonuses, benefits and share-based compensation expense related to individuals performing
research and development activities;

expenses incurred under agreements with third parties, including contract research organizations, or CROs, that conduct clinical trials and
research and development activities on our behalf, and contract manufacturing organizations that manufacture quantities of drug supplies for
both our preclinical studies and clinical trials;

the cost of consultants, including share-based compensation expense; and

various other expenses incident to the management of our preclinical studies and clinical trials.

Research and development costs are expensed as incurred. Nonrefundable advance payments for goods or services to be received in the future for

use in research and development activities are deferred and capitalized. The capitalized amounts are expensed as the related goods are delivered or the
services are performed. We have not provided program costs since inception because historically we have not tracked or recorded our research and
development expenses on a program-by-program basis.

93

 
 
 
 
The successful development of our product candidates is highly uncertain. Accordingly, at this time, we cannot reasonably estimate the nature,
timing and costs of the efforts that will be necessary to complete the remainder of the development of these product candidates. We are also unable to
predict when, if ever, material net cash inflows will commence from pegcetacoplan or any other potential product candidates. This is due to the numerous
risks and uncertainties associated with developing therapeutics, including the uncertainties of:

•

•

•

•

•

•

•

establishing an appropriate safety profile in preclinical studies;

successful enrollment in, and completion of clinical trials;

receipt of marketing approvals from applicable regulatory authorities;

establishing commercial manufacturing capabilities or making arrangements with third-party manufacturers;

obtaining and maintaining patent and trade secret protection and regulatory exclusivity for our product candidates;

launching commercial sales of the products, if and when approved, whether alone or in collaboration with others; and

an acceptable safety profile of the products following approval.

A change in the outcome of any of these variables with respect to the development of any of our product candidates would significantly change the

costs and timing associated with the development of that product candidate.

Research and development activities are central to our business model. Product candidates in later stages of clinical development generally have

higher development costs than those in earlier stages of clinical development, primarily due to the increased size and duration of later-stage clinical trials.
We expect research and development costs to increase significantly for the foreseeable future as our product candidate development programs progress.
However, we do not believe that it is possible at this time to accurately project total program-specific expenses through commercialization. There are
numerous factors associated with the successful commercialization of any of our product candidates, including future trial design and various regulatory
requirements, many of which cannot be determined with accuracy at this time based on our stage of development. Additionally, future commercial and
regulatory factors beyond our control will impact our clinical development programs and plans.

General and Administrative Expenses 

General and administrative expenses consist primarily of employee-related expenses including salaries, bonuses, benefits and share-based
compensation. Other significant costs include facility costs not otherwise included in research and development expenses, legal fees relating to patent and
corporate matters, and fees for accounting and consulting services.

We anticipate that our general and administrative expenses will increase in the future to support continued research and development activities,

potential commercialization of our product candidates and increased costs of operating as a public company. These increases will likely include increased
costs related to the hiring of additional personnel and fees to outside consultants, attorneys and accountants, among other expenses. Additionally, we
anticipate increased costs associated with being a public company including expenses related to services associated with maintaining compliance with
exchange listing and SEC requirements, insurance costs and investor relations costs.

Critical Accounting Policies and Estimates 

This discussion and analysis of our financial condition and results of operations is based on our financial statements, which we have prepared in

accordance with U.S. generally accepted accounting principles. The preparation of these financial statements requires us to make estimates and
assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial
statements, as well as the reported amounts of expenses during the reporting periods. On an ongoing basis, we evaluate our estimates and judgments,
including those described in greater detail below. We base our estimates on historical experience and on various other factors that we believe are reasonable
under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily
apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

While our significant accounting policies are described in more detail in Note 2 in the notes to our consolidated financial statements included
elsewhere in this Annual Report on Form 10-K, we believe that the following accounting policies are the most critical to aid you in fully understanding and
evaluating our financial condition and results of operations.

Licensing Revenue

On October 27, 2020, we entered into the collaboration agreement with Sobi concerning the development and commercialization of pegcetacoplan

and specified other compstatin analogues or derivatives for use systemically or for local non-ophthalmic administration, collectively referred to as the
Licensed Products. See “Business—Collaboration and License Agreement with Sobi” for a description of the key terms of our collaboration agreement
with Sobi.

The Company has determined that the collaboration agreement is within the scope of FASB ASC Topic 808, Collaborative Arrangements (“ASC

808”) as a contractual arrangement that involves a joint operating activity whereby both parties are (i) active participants in the activity and (ii) exposed to
certain significant risks and rewards dependent on the commercial success of the activity.  ASC Topic 808 does not address measurement or recognition
matters but allows for analogizing to ASC 606, Revenue from Contracts with Customers (“ASC 606”).  Pursuant to ASC 606, we performed the following
five steps: (i) identified the contract with a customer; (ii) identified the performance obligations in the contract; (iii) determined the transaction price; (iv)
allocated the transaction price to the performance obligations in the contract; and (v) recognized revenue when the entity satisfied a performance
obligation.  

We identified the following material promises under the Sobi Agreement: (1) licenses to develop and commercialize pegcetacoplan or, Licenses to

IP, and (2) performance of research and development services.  We determined the promises to be distinct because Sobi can benefit from each of the license
and the development services on their own or with readily available services.  We could have provided the license without any development services and
Sobi would have been able to benefit from it by obtaining development services from another provider as the Licensed Products products are at a more
mature stage in their life cycle.   

Under the collaboration agreement, Sobi agreed to pay us
i)
ii)

a fixed amount of $250.0 million in an upfront payment in November 2020;
a fixed amount of an additional $80.0 million in development reimbursements, payable yearly in four tranches in amounts determined
based upon actual expenses incurred by us;    
up to an aggregate of $915.0 million upon the achievement of specified one-time regulatory and commercial milestone events; and
tiered, double-digit royalties, ranging from high teens to high twenties, on sales of Licensed Products outside of the United States, subject
to customary deductions and third-party payment obligations.  

iii)
iv)

At inception of the collaboration agreement, we considered the $250.0 million non-refundable payment and the $80.0 million fixed proceeds. We

also evaluated whether Sobi is a customer for either of the distinct promises in the agreement.  Under the Licenses to IP, we determined that Sobi is a
customer as the know-how provided and the right granted by us to Sobi are outputs of our business activities for which we will receive consideration.  
With respect to research and development activity, management determined that there is no vendor relationship as performing research and development
activities for others is not a part of our ongoing central operations.  Based upon the evaluation of the relative fair values, we allocated the purchase price of
$250.0 million and the related milestones and royalties to the license of IP and $80.0 million to performance of research and development activities.

The milestone and royalty payments are subject to activities outside our control.  Per ASC 606, we consider this to be a customer/ vendor
relationship, therefore, we will include the regulatory milestone payments in the total transaction price when it is probable that a significant reversal of
revenue would not occur in a future period. We will recognize commercial milestone and royalty revenue at the later of (i) when the related sales occur or
(ii) when the performance obligation to which the commercial milestone or royalty has been allocated has been satisfied.  In case of commercial milestone
or royalty payments, we will recognize revenue in the same period that the sales are completed for which we are contractually entitled to the milestone or
percentage-based royalty payment.   To date, we have not recognized any commercial milestone or royalty revenue resulting from any of our licensing
arrangements.  Management will periodically assess the elements of the contract and re-evaluate revenue recognition as necessary.

Pursuant to ASC 606, the $250.0 million non-refundable upfront payment is recognized in revenue as this is the amount allocated to the license.  The
$80.0 million reimbursement for research and development activities does not constitute a customer/vendor relationship and thus is not in the scope of ASC
606.  As ASC 808 does not include recognition guidance we have established an accounting policy to recognize the payments under the reimbursement as a
receivable on the balance sheet in an amount that is to be reimbursed based upon expense incurred by us, with a contra- research and development expense
recognized in the statement of operations, over time as the expenses are incurred.

Under the Sobi collaboration agreement, for the year ended December 31, 2020, we recognized $250.0 million of licensing revenue in the

consolidated statement of operations.  For the year ended December 31, 2020, we also recognized in the consolidated statement of operations $43.0 million
of contra research and development expense relative to the amount expected to be reimbursed under the $80.0 million for research and development
incurred expenses.  We also recognized a corresponding receivable of $43.0

95

 
 
 
 
 
million, with $25.0 million in current and $18.0 million in long term assets, respectively, on the consolidated balance sheet as of December 31, 2020.

In addition to the Sobi collaboration agreement, during the year ended December 31, 2020, we entered into two different agreements with third
parties to provide APL-9 for use in certain research projects for which $0.6 million was recognized in revenue in the consolidated statement of operations
as of December 31, 2020.  

Accrued Research and Development Expenses 

As part of the process of preparing our financial statements, we are required to estimate our accrued expenses. This process involves reviewing

quotations and contracts, identifying services that have been performed on our behalf and estimating the level of service performed and the associated cost
incurred for the service when we have not yet been invoiced or otherwise notified of the actual cost. The majority of our service providers invoice us
monthly in arrears for services performed or when contractual milestones are met. We make estimates of our accrued expenses as of each balance sheet date
in our financial statements based on facts and circumstances known to us at that time. We periodically confirm the accuracy of our estimates with the
service providers and make adjustments if necessary. The significant estimates in our accrued research and development expenses include the costs
incurred for services performed by CROs and contract manufacturing organizations, or CMOs, in connection with research and development activities for
which we have not yet been invoiced.

We base our expenses related to CROs and CMOs on our estimates of the services received and efforts expended pursuant to quotes and contracts

with CROs and CMOs. The financial terms of these agreements are subject to negotiation, vary from contract to contract and may result in uneven payment
flows. There may be instances in which payments made to our CROs and CMOs will exceed the level of services provided and result in a prepayment of
the research and development expense. In accruing service fees, we estimate the time period over which services will be performed and the level of effort
to be expended in each period. If the actual timing of the performance of services or the level of effort varies from our estimate, we adjust the accrual or
prepaid expense accordingly. Although we do not expect our estimates to be materially different from amounts actually incurred, if our estimates of the
status and timing of services performed differ from the actual status and timing of services performed, it could result in us reporting expense amounts that
are too high or too low in any particular period. To date, there have been no material differences between our estimates of such expenses and the amounts
actually incurred.

Convertible Notes

On September 16, 2019, we completed a private offering of the 2019 Convertible Notes with an aggregate principal amount of $220.0 million. On

May 12, 2020, we issued the 2020 Convertible Notes with an aggregate principal amount of $300.0 million.

The Convertible Notes are convertible into shares of our common stock at an initial conversion rate of 25.3405 shares per $1,000 principal amount

of the Convertible Notes, equivalent to an initial conversion price of approximately $39.46 per share of common stock. The conversion rate is subject to
customary anti-dilution adjustments. In addition, following certain events that occur prior to the maturity date or if we deliver a notice of redemption, we
are required to increase the conversion rate for a holder who elects to convert its notes in connection with such corporate event or a notice of redemption, as
the case may be, in certain circumstances as provided in the Indenture. The Convertible Notes will also be subject to redemption at our option, on or after
September 20, 2023, if certain conditions are met. The redemption price is equal to 100% of the principal amount of the notes to be redeemed, plus accrued
and unpaid interest to, but excluding, the redemption date.

Pursuant to Accounting Standards Codification (“ASC”) Subtopic 470-20 Convertible Debt, we used an effective interest rate of 10.5% to determine

the liability component of the Convertible Notes. This resulted in the recognition of $145.1 million and $204.5 million as the liability component of the
2019 and 2020 Convertible Notes, respectively and the recognition of the residual amount of $74.9 million and $95.5 million as the debt discount with a
corresponding increase to additional paid in capital for the equity component of the 2019 and 2020 Convertible Notes, respectively. The 2020 Convertible
Notes aggregate debt issuance costs of $6.0 million were allocated to the liability and equity components in the amounts of $3.7 and $2.3 million,
respectively.  The 2019 Convertible Notes aggregate debt issuance costs of $7.1 million were allocated to the liability and equity components in the
amounts of $4.7 million and $2.4 million, respectively.  

On January 6, 2021, subsequent to year end, we entered into separate, privately negotiated exchange agreements with certain holders of its 2019

Convertible Notes.  Under the terms of these exchange agreements, the holders exchanged approximately $126.1 million in aggregate principal amount of
2019 Convertible Notes held by them for (i) 2,232,808 shares of our common stock, which is equal to 20.7792 shares per $1,000 principal amount of the
2019 Convertible Notes exchanged plus (ii) an additional number of shares of our common stock per $1,000 principal amount of the 2019 Convertible
Notes exchanged equal to the quotient of (a) $544.07 divided by (b) the average of the daily volume-weighted average prices of our common stock over the
ten consecutive trading days commencing on January 7, 2021. We issued an aggregate of 3,906,869 shares of common stock upon settlement of the
exchanges in

96

January 2021. As of the date of this Annual Report on Form 10-K, we hold the $126.1 million principal amounts of exchanged notes and such notes have
not been cancelled.

Capped Call Transactions

On September 11, 2019, and May 6, 2020 concurrently with the pricing of the 2019 Convertible Notes and 2020 Convertible Notes, respectively,
we entered into capped call transactions with two counterparties. The capped call transactions are expected generally to reduce the potential dilution to our
common stock upon any conversion of notes and/or offset any cash payments we are required to make in excess of the principal amount of the Convertible
Notes, as the case may be, in the event that the market price per share of our common stock, as measured under the terms of the capped call transactions, is
greater than the strike price of the capped call transactions, which is initially $39.4625 (the conversion price of the Convertible Notes) and is subject to
anti-dilution adjustments substantially similar to those applicable to the conversion rate of such notes. If, however, the market price per share of the
Company’s common stock, as measured under the terms of the capped call transactions, exceeds the cap price of the capped call transactions, which is
initially $63.14 per share, there would nevertheless be dilution and/or there would not be an offset of such potential cash payments, in each case, to the
extent that such market price exceeds the cap price of the capped call transactions.

Pursuant to ASC 815-40 Derivatives and Hedging, we determined that the capped call transactions should be classified as equity instruments and

the capped call premiums paid in the amount of $28.4 million and $43.1 million were recorded as a reduction to additional paid-in capital as of December
31, 2019 and December 31, 2020 for the 2019 Convertible Notes and 2020 Convertible Notes, respectively.

Development Derivative Liability  

Following regulatory approval by the FDA or the EMA, for the use of pegcetacoplan as a treatment for PNH we will be obligated to pay SFJ an

initial payment of up to $5.0 million (or a total of up to $10.0 million if regulatory approval is granted by the FDA and the EMA) and then up to an
additional $226.0 million in the aggregate (or up to $452.0 million if regulatory approval is granted by the FDA and the EMA) in six additional annual
payments with the majority of the payments being made from the third anniversary to the sixth anniversary of regulatory approval. Such payments will be
proportionately adjusted in the event that the actual funding from SFJ is greater than $120.0 million (including as a result of the payment of the Additional
SFJ Funding but excluding the $20.0 million funding payment made under the SFJ amendment).

The SFJ agreement is presented as a derivative liability on the consolidated balance sheet as of December 31, 2020. The liability was initially
recorded at the value of the $60.0 million of aggregate cash received pursuant to the contractual terms, which was determined to have been fairly valued as
a level 3 derivative. During the years ended December 31, 2020 and 2019, we received an additional $20.0 million and $60.0 million, respectively, as we
met certain milestones.  The SFJ agreement is remeasured quarterly as a level 3 derivative, with the total change in fair value for the years ended December
31, 2020 and 2019 of $103.0 million and $14.8 million, respectively, recorded in loss from remeasurement of development derivative liability on the
consolidated income statement.

The derivative is valued using a scenario-based discounted cash flow method, whereby each scenario makes assumptions about the probability and

timing of cash flows, and such cash flows are present valued using a risk-adjusted discount rate. The analysis is calibrated such that the value of the
derivative as of the date of the SFJ agreement was consistent with an arm’s-length transaction. Key inputs to the level 3 fair value model include (i) the
probability and timing of achieving stated development goals to receive the next tranches of funding, (ii) the probability and timing of achieving FDA and
EMA approval, (iii) SFJ’s cost of borrowing (8.0%), and (iv) our cost of borrowing (12.65%).

SFJ’s implied cost of borrowing was 8.0% and our implied cost of borrowing was 12.65% as of the reporting date. These implied costs of
borrowing were determined assuming the SFJ agreement was initially executed with arm’s-length terms. If the SFJ agreement was instead not determined
to be an arm’s-length transaction, then implied discount rates could differ.

If actual results or events differ materially from the estimates, judgments and assumptions used by us in applying these policies, our reported

financial condition and results of operations could be materially affected. See Note 5 to the consolidated financial statements included in Item 15 in this
Annual Report on Form 10-K for more information.

Licensing revenue increased $250.5 million for the year ended December 31, 2020 as compared to the year ended December 31, 2019. The increase
is primarily due to the Collaboration and Licensing Agreement we entered with Sobi in October 2020 concerning the development and commercialization
of pegcetacoplan and specified other compstatin analogues or derivatives for use systemically or for local non-ophthalmic administration.  Sobi paid us an
upfront payment of $250.0 million in November 2020, which is recognized in licensing revenue in the consolidated statement of operations as of December
31, 2020.  

Additionally, during the year ended December 31, 2020, we entered into two different licensing and collaboration agreements with third parties to

provide APL-9 for use in certain research project which totaled $0.6 million for the year ended December 31, 2020.

Research and development expenses increased by $104.0 million to $325.0 million for the year ended December 31, 2020 from $221.0 million for

the year ended December 31, 2019, an increase of 47%. The increase in research and development expenses was primarily attributable to an increase of
$37.1 million in manufacturing expenses in connection with the supply of pegcetacoplan for our Phase 3 clinical trials and in preparation for commercial
launch, an increase of $15.6 million in clinical trial costs associated with the on-going Phase 3 trials and the preparation for and commencement of our
clinical trials in other indications, an increase of $38.8 million in compensation and related personnel costs primarily due to the hiring of additional
personnel in 2020, an increase of $21.7 million in research and development supporting activities caused primarily by increased regulatory and quality
expenses, an increase of $25.0 million for the licensee fee to Penn related to the Sobi transaction, an increase in research and innovation expense of $10.1
million and an increase of $0.6 million in device development expenses.  These increases were offset by a $43.0 million contra research and development
expense related to the Sobi transaction and a decrease of $1.9 million related to preclinical study expense. We expect our research and development
expenses to continue to increase as the number of patients in our trials increases and the number of ongoing trials increases.

General and Administrative Expenses

General and administrative expenses increased by $72.4 million to $139.4 million for the year ended December 31, 2020, from $67.0 million for the

year ended December 31, 2019, an increase of 108%. The increase in general and administrative expenses was primarily attributable to an increase in
professional and consulting fees of $35.5 million, an increase in employee related costs of $33.8 million due to the hiring of additional personnel, an
increase in directors stock compensation expense of $1.8 million ,an increase in insurance costs of $1.1 million, and an increase in office, travel and related
costs of $0.6 million, offset by a decrease of $0.4 million in information technology expenses. The increased professional and consulting fees of $35.5
million primarily consisted of an increase in expenses relating to preparation for commercial launch of $29.3 million, an increase of $4.5 million in
accounting and legal fees, and an increase in general consulting fees of $2.6 million, offset by a decrease in communication and public relations fees of
$0.9 million. The increased employee related costs of $33.8 million consisted of $21.9 million related to an increase in salaries and benefits primarily due
to the hiring of additional personnel and $12.3 million related to stock option expense associated with the grants of stock options and restricted stock units
to employees, offset by a decrease of $0.4 million in recruitment expense.

Loss on Extinguishment of Debt

On March 26, 2019, we repaid all outstanding amounts due and owed, including applicable termination fees, under our term loan facility with
Silicon Valley Bank. The final payment included the outstanding balance of the term loan as well as (i) a prepayment fee contractually owed of $0.1
million, (ii) a final payment equal to 8% of the original principal amount of the term loan, or $1.6 million, and (iii) per diem interest of $0.1 million, for a
total payment of $21.8 million, which resulted in a loss on extinguishment of debt of $1.2 million. On September 16, 2019, we repaid outstanding amounts
due and owed on the promissory note with Golda Darty Partners, S.A. or GDP. The remaining discount on the promissory note related to the issuance of
warrants in connection with the issuance of the promissory note resulted in a loss on extinguishment of debt of $0.3 million.  

Loss from Remeasurement of Development Derivative Liability

On February 28, 2019, we entered into the SFJ agreement under which SFJ agreed to provide funding to us to support the development of
pegcetacoplan for the treatment of patients with PNH. The development derivative liability was initially recorded at the value of the $60.0 million
aggregate cash received pursuant to the contact terms.

The SFJ agreement was amended on June 7, 2019 to provide for additional funding and we received $20.0 million upon execution of the SFJ

amendment in June 2019 and in each of September 2019 and January 2020, we achieved a $20.0 million development milestone under the terms of the
agreement, resulting in receipt of an aggregate of $60.0 million of additional funding from SFJ.

We remeasure the fair value of the derivative liability as a level 3 derivative at the end of each quarter. The remeasurements resulted in a change in
fair value which resulted in a loss of $103.0 million and $14.8 million recorded in the consolidated statement of operations for the years ended December
31, 2020 and 2019, respectively.  

Interest Expense

Interest expense was $29.9 million for the year ended December 31, 2020, an increase of $24.6 million, compared to $5.3 million for the year ended

December 31, 2019. The increase in interest expense was primarily attributable to the interest expense on and amortization of the discount on the
Convertible Notes offset by the decrease in interest expense attributable to our long-term debt under the term loan facility that we repaid in March 2019 and
the promissory note that we repaid in 2019.

99

 
Interest Income

Interest income was $4.2 million for the year ended December 31, 2020, a decrease of $.9 million, compared to $5.1 million for the year ended

December 31, 2019. The decrease in interest income was primarily attributable to a decline in investment yields and interest rates.

Other Expense, Net

Other expense increased $0.3 million for the year ended December 31, 2020 as compared to the year ended December 31, 2019.  The increase was

primarily related to corporate franchise taxes and fees.

Income Tax Expense

Income tax expense increased $1.8 million for the year ended December 31, 2020 as compared to the year ended December 31, 2019.  The increase

was primarily related to foreign and state income tax expense.

Comparison of the Years Ended December 31, 2019 and 2018

A discussion of changes in our results of operations during the year ended December 31, 2019 compared to the year ended December 31, 2018 has

been omitted from this Annual Report on Form 10-K but may be found in “Item 7. Management’s Discussion and Analysis of Financial Condition and
Results of Operations” in our Annual Report on Form 10-K for the year ended December 31, 2019, filed with the SEC on February 27, 2020, which
discussion is incorporated herein by reference and which is available free of charge on the SECs website at www.sec.gov.

Liquidity and Capital Resources 

Sources of Liquidity

To date, we have financed our operations primarily through $772.1 million in net proceeds from public offerings of our common stock, including

our IPO, $535.8 million in net proceeds from offerings of Convertible Notes, a $250.0 million upfront payment and a $25.0 million development
reimbursement payment from Sobi each pursuant to the Sobi collaboration agreement, $112.6 million in proceeds from the private placement of shares of
our convertible preferred stock prior to our IPO, $140.0 million under the SFJ agreement, $20.0 million in proceeds from borrowings under a term loan
facility with Silicon Valley Bank, and $7.0 million in proceeds from our issuance and sale of a promissory note. We have repaid the term loan facility and
the promissory note in full, and we exchanged $126.1 million of aggregate principal amount of 2019 Convertible Notes for shares of our common stock in
January 2021.

On April 23, 2018, we issued and sold 5,500,000 shares of our common stock in a follow-on public offering at a public offering price of $25.50 per

share for net proceeds of $131.2 million, after deducting underwriting discounts and commissions of $8.4 million and offering expenses of $0.5 million.

On March 11, 2019, we issued and sold 6,900,000 shares of our common stock in a follow-on offering at a public offering price of $17.00. We

received net proceeds of $109.6 million after deducting underwriting discounts and commissions of $7.0 million and offering costs of $0.7 million.

On September 16, 2019, we completed a private offering of $220.0 million aggregate principal amount of Convertible Notes. We received net

proceeds of approximately $212.9 million after deducting the initial purchasers’ discounts and commissions and offering costs of $7.1 million.

On January 13, 2020, we issued and sold 10,925,000 shares of our common stock in a follow-on offering at a public offering price of $37.00,
including 1,425,000 shares sold pursuant to the underwriters’ exercise in full of their option to purchase additional shares of common stock. We received
total net proceeds of $381.4 million after deducting underwriting discounts and commissions of $22.2 million and offering costs of $0.5 million.

On May 12, 2020, we completed a private offering of $300.0 million aggregate principal amount of 2020 Convertible Notes. We received net
proceeds of approximately $322.9 million, which included accrued interest March 15, 2020 to, but not including May 12, 2020, and the initial purchasers’
discounts and commissions and offering costs of $6.0 million.

Subsequent to year end, on January 6, 2021, we entered into separate, privately negotiated exchange agreements with certain holders of our 2019

Convertible Notes.  Under the terms of these exchange agreements, the holders exchanged approximately $126.1

100

million in aggregate principal amount of 2019 Convertible Notes held by them for an aggregate of 3,906,869 shares of our common stock. The exchange
transactions closed in January 2021.

In addition to our existing cash, cash equivalents and marketable securities, we expect to receive research and development reimbursements and are

eligible to earn development and commercial milestone payments and royalties under our collaboration agreement with Sobi. Our ability to earn these
milestone payments and the timing of earning these payments is dependent upon the outcome of our research and development and commercialization
activities and is uncertain at this time.

The capped call transactions that we entered into concurrently with the issuance of the Convertible Notes are expected generally to reduce the
potential dilution to our common stock upon any conversion of Convertible Notes and/or offset any cash payments we are required to make in excess of the
principal amount of converted Convertible Notes, as the case may be, in the event that the market price per share of our common stock, as measured under
the terms of the capped call transactions, is greater than the strike price of the capped call transactions, which is initially $39.4625, the conversion price of
the Convertible Notes.

Net Cash Used in Operating Activities 

Net cash used in operating activities was $160.5 million for the year ended December 31, 2020 and consisted primarily of a net loss of $344.9
million adjusted for $164.8 million of non-cash items, including a loss from remeasurement of development derivative liability of $103.0 million and
share-based compensation expense of $45.4 million, a net increase in operating assets of $35.4 million, an increase in accounts payable and accrued
expenses of $55.0 million.  

Net cash used in operating activities was $211.1 million for the year ended December 31, 2019 and consisted primarily of a net loss of $304.7

million adjusted for $40.4 million of non-cash items, including share-based compensation expense of $21.1 million, a loss from remeasurement of
development derivative liability of $14.8 million, and a loss on early extinguishment of debt of $1.5 million, a net increase in accounts payable, accrued
expenses and other liabilities of $48.7 million and a net decrease in operating assets of $4.5 million. The net increase in operating liabilities resulted
primarily from an increase in accrued expenses of $50.5 million.

Net Cash Used in Investing Activities

Net cash used in investing activities during the year ended December 31, 2020 was $317.0 million due primarily to the purchase of marketable
securities with proceeds from the follow-on common stock offering in January 2020, the issuance of the 2020 Convertible Notes in May 2020 and the
$250.0 million from the Sobi agreement offset by the maturities of some of these investments.

Net cash used in investing activities during the year ended December 31, 2019 was $1.7 million due to the purchase of fixed assets for our offices.

Net Cash Provided by Financing Activities

Net cash provided by financing activities was $692.2 million during the year ended December 31, 2020 and consisted primarily of proceeds from
the follow-on common stock offering in January 2020 of $381.4 million, the proceeds from the issuance of the 2020 Convertible Notes in May 2020 of
$322.9 million, the receipt of $20.0 million from the SFJ agreement and $11.0 million upon the exercise of stock options and the employee share purchase
plan, offset by the $43.1 million used to purchase the capped call.

Net cash provided by financing activities was $388.5 million during the year ended December 31, 2019 and consisted primarily of proceeds from

the issuance of the Convertible Notes in September 2019 of $212.9 million, the issuance of common stock in our March follow-on offering of $109.6
million, the receipt of $120.0 million from the SFJ agreement and $3.1 million upon the exercise

101

 
 
 
 
 
   
 
   
   
   
 
 
of stock options, offset by $28.7 million for the repayment of our term loan facility and promissory note, and $28.4 million for capped call premiums paid.

Funding Requirements

We expect our expenses to increase in connection with our ongoing activities, particularly as we continue the research and development of, and seek

marketing approval for, our product candidates. In addition, if we obtain marketing approval for any of our product candidates, we expect to incur
significant commercialization expenses related to product sales, marketing, manufacturing and distribution. Furthermore, we expect to continue to incur
additional costs associated with operating as a public company. Accordingly, we will need to obtain substantial additional funding in connection with our
continuing operations. If we are unable to raise capital when needed or on attractive terms, we would be forced to delay, reduce or eliminate our research
and development programs or future commercialization efforts.

We believe that our cash and cash equivalents and marketable securities as of December 31, 2020 will enable us to fund our operating expenses and
capital expenditure requirements at least into the second half of 2022. We have based this estimate on assumptions that may prove to be wrong, and we may
use our available capital resources sooner than we currently expect. Although we expect that our cash, cash equivalents and marketable securities will be
sufficient to allow us to complete the DERBY and OAKS clinical trials, we do not believe they will be sufficient to allow us to support both the systemic
and ophthalmological pegcetacoplan programs through commercial launch. Because of the numerous risks and uncertainties associated with the
development of pegcetacoplan and other potential product candidates, and because the extent to which we may enter into collaborations with third parties
for the development of these product candidates is unknown, we are unable to estimate the amounts of increased capital outlays and operating expenses
associated with completing the research and development of our product candidates. Our future funding requirements will depend on many factors,
including:

•

•

•

•

•

•

•

•

•

•

•

•

•

the scope, progress, timing, costs and results of clinical trials of, and research and preclinical development efforts for pegcetacoplan, APL-9
and future product candidates;

our ability to maintain a productive collaborative relationship with Sobi with respect to pegcetacoplan, including our ability to achieve
milestone payments under our agreement with Sobi;

our ability to identify additional collaborators for any of our product candidates and the terms and timing of any collaboration agreement that
we may establish for the development and any commercialization of such product candidates;

the number and characteristics of future product candidates that we pursue and their development requirements;

the outcome, timing and costs of clinical trials and of seeking regulatory approvals of pegcetacoplan and other product candidates we may
pursue;

the costs of commercialization activities for any of our product candidates that receive marketing approval to the extent such costs are not the
responsibility of any collaborators, including the costs and timing of establishing product sales, marketing, distribution and manufacturing
capabilities;

subject to receipt of marketing approval, revenue, if any, received from commercial sales of pegcetacoplan and our other product candidates;

our headcount growth and associated costs as we expand our research and development and establish a commercial infrastructure;

the costs of preparing, filing and prosecuting patent applications, maintaining and protecting our intellectual property rights and defending
against intellectual property related claims;

the effect of competing technological and market developments;

the effect of the COVID-19 pandemic on the healthcare system and the economy generally and on our clinical trials and other operations
specifically;

our ability to obtain adequate reimbursement for any product we commercialize; and

the costs of operating as a public company.

Identifying potential product candidates and conducting preclinical testing and clinical trials is a time-consuming, expensive and uncertain process
that takes years to complete, and we may never generate the necessary data or results required to obtain marketing approval and achieve product sales. In
addition, our product candidates, if approved, may not achieve commercial success. Our commercial revenues, if any, will be derived from sales of
medicines that we do not expect to be commercially available for many

102

 
 
 
 
 
 
 
 
 
 
 
 
 
years, if at all. Accordingly, we will need to continue to rely on additional financing to achieve our business objectives. Adequate additional financing may
not be available to us on acceptable terms, or at all.

Until such time, if ever, as we can generate substantial product revenues, we expect to finance our cash needs through a combination of equity
offerings, debt financings, collaborations, strategic alliances and licensing arrangements. We currently do not have any committed external source of funds.
To the extent that we raise additional capital through the sale of equity or convertible debt securities, our stockholders’ ownership interests will be diluted,
and the terms of these securities may include liquidation or other preferences that adversely affect our stockholders’ rights. Debt financing, if available,
would result in fixed payment obligations and may involve agreements that include restrictive covenants that limit our ability to take specific actions, such
as incurring additional debt, making capital expenditures or declaring dividends, that could adversely impact our ability to conduct our business.

If we raise funds through collaborations, strategic alliances or licensing arrangements with third parties, we may have to relinquish valuable rights to

our technologies, future revenue streams, research programs or product candidates or to grant licenses on terms that may not be favorable to us. If we are
unable to raise additional funds through equity or debt financings when needed, we may be required to delay, limit, reduce or terminate our product
development or future commercialization efforts or grant rights to develop and market product candidates that we would otherwise prefer to develop and
market ourselves.

Amounts include interest on long-term debt represents obligations under the debt outstanding as of December 31, 2020, applying contractual fixed
interest rate and assuming scheduled payments are paid as contractually required through maturity. Subsequent to year end, in January 2021, we
entered into an agreement to exchange $126.1 million of our 2019 Convertible Notes for shares of common stock. See Note 20 to the consolidated
financial statements included in Item 15 in this Annual Report on Form 10-K for more information.
Equals the non-cancellable purchase commitments under the Bachem Agreement signed with Bachem on December 30, 2020,
Represents future minimum lease payments under our non-cancelable operating leases. The minimum lease payments above do not include any
related common area maintenance charges or real estate taxes.

On February 28, 2019, we entered into the SFJ agreement. Under the SFJ agreement, following regulatory approval by the FDA or the EMA of the

use of pegcetacoplan as a treatment for PNH, we will be obligated to pay SFJ an initial payment of up to $5.0 million (or up to a total of $10 million if
regulatory approval is granted by the FDA and the EMA) and then up to an additional $226.0 million in the aggregate (or up to $452.0 million if regulatory
approval is granted by the FDA and the EMA) in six additional annual payments with the majority of the payments being made from the third anniversary
to the sixth anniversary of regulatory approval. The timing and likelihood of such payments are not currently known.

During the third quarter of 2019, we entered into contracts to conduct research and development activities with third parties which commit us to pay
future milestone payments up to $15.0 million or to pay royalty fees ranging from 3-6% if any of the research results in regulatory approval or commercial
revenue for a product. The scope of the services under the research and development contracts can be modified and the contracts cancelled by us upon
written notice. In some instances, the contracts may be cancelled by the third party upon written notice. If we were to cancel these contracts, we would be
required only to pay for activities incurred through termination date. We have not included any of these potential payments in the contractual obligations
table above, as we cannot reasonably estimate whether, when and in what amount any of such payments shall be made.

We are party to two license agreements with Penn under which we license specified intellectual property from Penn. The patent rights licensed to us by

Penn include patents with claims that recite a class of compounds generically covering pegcetacoplan. Each license agreement requires us to pay ongoing annual
maintenance payments of $100,000 per year until the first commercial sale of a licensed product. With respect to the license for the nonophthalmic field of use,
we have agreed to make milestone payments to Penn aggregating up to $1.7 million based on achieving specified development and regulatory approval
milestones, and up to $2.5 million based on achieving specified annual sales milestones with respect to each of the first two licensed products. In 2018 we made
one milestone payment of $0.4 million under the nonophthalmic license. With respect to the license for the ophthalmic field of use, we have agreed to make
milestone payments to Penn aggregating up to $3.2 million based on achieving specified development and regulatory milestones, and up to $5.0

million based on achieving specified annual sales milestones.  In 2018 we made one milestone payment, net of credits for the annual maintenance payment, of
$0.7 million under the ophthalmic license. The license agreements also require that we pay low single-digit royalties to Penn based on net sales of each licensed
product by us and our affiliates and sublicensees and specified minimum quarterly royalty thresholds. In addition, we are obligated to pay Penn a specified
portion of income we receive from sublicensees. In January 2021 we paid Penn $25.0 million as a sublicensee fee under these agreements relating to the Sobi
agreement. We have not included any of these potential payments in the contractual obligations table above, as we cannot reasonably estimate whether, when and
in what amount any of such payments shall be made.

We enter into agreements in the normal course of business with CROs for clinical trials and clinical supply manufacturing and with vendors for

preclinical research studies and other services and products for operating purposes. We have not included these payments in the table of contractual
obligations above since either the contracts are cancelable at any time by us, generally upon 30 days prior written notice to the CRO, or the noncancelable
minimum purchase commitments under such contracts have already been satisfied, and therefore we believe that our non-cancelable obligations under these
agreements are not material. Under these agreements, as of December 31, 2020, we are obligated to pay up to $2.8 million to these vendors.

We have certain non-cancelable purchase obligations related to the manufacturing of drug substance and drug product, primarily with Bachem

Americas, Inc, and Bachem AG, for the drug substance for the finished dosage form of pegcetacoplan.  

Off-Balance Sheet Arrangements 

We did not have during the periods presented, and we do not currently have, any off-balance sheet arrangements, as defined under applicable SEC

rules.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk.

We are exposed to market risk related to changes in interest rates. As of December 31, 2020, we had cash, cash equivalents and marketable
securities of $877.6 million, consisting primarily of money market funds and U.S. treasury securities. Our primary exposure to market risk is interest rate
sensitivity, which is affected by changes in the general level of U.S. interest rates. Due to the short-term duration of our investment portfolio and the low
risk profile of our investments, an immediate 10% change in interest rates would not have a material effect on the fair market value of our investment
portfolio. We have the ability to hold our marketable securities until maturity, and therefore we would not expect our operating results or cash flows to be
affected to any significant degree by the effect of a change in market interest rates on our investments.

Item 8. Financial Statements and Supplementary Data.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders and the Board of Directors of Apellis Pharmaceuticals, Inc.

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of Apellis Pharmaceuticals, Inc. and subsidiaries (the “Company”) as of December 31,
2020 and 2019, the related consolidated statements of operations and comprehensive loss, stockholders’ equity, and cash flows, for each of the two years in
the period ended December 31, 2020, and the related notes (collectively referred to as the “financial statements”). In our opinion, the financial statements
present fairly, in all material respects, the financial position of the Company as of December 31, 2020 and 2019, and the results of its operations and its
cash flows for each of the two years in the period ended December 31, 2020, in conformity with accounting principles generally accepted in the United
States of America.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s
internal control over financial reporting as of December 31, 2020, based on criteria established in Internal Control—Integrated Framework (2013) issued
by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 25, 2021, expressed an unqualified opinion on
the Company’s internal control over financial reporting.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial
statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the
Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the
PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing
procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to
those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits
also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the
financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current-period audit of the financial statements that was communicated or
required to be communicated to the audit committee and that (1) relates to accounts or disclosures that are material to the financial statements and (2)
involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion
on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical
audit matter or on the accounts or disclosures to which it relates.

Development Derivative Liability — Refer to Notes 4 and 10 to the financial statements.

Critical Audit Matter Description

On February 28, 2019, the Company entered into a development funding agreement with SFJ Pharmaceuticals Group (“SFJ”) under which SFJ agreed to
provide funding to the Company to support the development of one the Company’s clinical trials (“SFJ Agreement”). The SFJ Agreement is presented as a
derivative liability whose fair value is based on unobservable inputs. The liability is initially recorded at the value of the aggregate cash received pursuant
to the contractual terms and is subsequently remeasured at each quarter with the change in fair value recorded in loss from remeasurement of development
derivative liability on the income statement.  

We identified the valuation of the development derivative liability as a critical audit matter.  The development derivative liability is valued using a scenario-
based discounted cash flow method, whereby each scenario makes assumptions about the probability and timing of cash flows, and such cash flows are
present valued using a risk-adjusted discount rate. This model includes unobservable inputs including the probability and timing of achieving U.S. Food
and Drug Administration (FDA) and European Medicines Agency (EMA) approval and Company’s cost of borrowing. This required a high degree of
auditor judgment and an increased extent of effort, including the need to involve our fair value specialists.

105

 
 
  
How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to the development derivative liability model and unobservable inputs used by management to estimate the fair value of the
development derivative liability included the following, among others:

• We tested the effectiveness of controls over management’s valuation of the development derivative liability such as those related to management’s

assumptions over the probability and timing of achieving FDA and EMA approval and the review of the discount rate.

• We evaluated the reasonableness of management’s assumptions over the probability and timing of achieving FDA and EMA approval by comparing

the assumptions within the model to:

-
-
-

Internal communications to management and the Board of Directors.
Information included in Company press releases as well as in analyst reports for the Company.
Inquiries with those responsible for clinical affairs regarding the progress of ongoing trials.

• With the assistance of our fair value specialists, we evaluated the reasonableness of the valuation methodology including the discount rate used by

testing the source information and the mathematical accuracy of the calculation.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders and the Board of Directors of Apellis Pharmaceuticals, Inc.

Opinion on the Financial Statements

We  have  audited  the  accompanying  consolidated  statements  of  operations  and  comprehensive  loss,  changes  in  stockholders'  equity  and  cash  flows  of
Apellis Pharmaceuticals, Inc. (the Company) for the year ended December 31, 2018, and the related notes (collectively referred to as the “consolidated
financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the results of the Company’s operations
and its cash flows for the year ended December 31, 2018, in conformity with U.S. generally accepted accounting principles.

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company’s financial
statements based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company
in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audit included performing procedures
to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks.
Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audit also included
evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial
statements. We believe that our audit provides a reasonable basis for our opinion.

We served as the Company’s auditor from 2015 to 2019.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Nature of Organization and Operations

Apellis Pharmaceuticals, Inc. (the “Company”) is a clinical-stage biopharmaceutical company focused on the development of novel therapeutic

compounds to treat disease through the inhibition of the complement system, which is an integral component of the immune system, at the level of C3, the
central protein in the complement cascade.

The Company was incorporated in September 2009 under the laws of the State of Delaware. The Company’s principal executive offices are located

in Waltham, Massachusetts, effective January 1, 2020.

The Company’s operations since inception have been limited to organizing and staffing the Company, acquiring rights to product candidates,

business planning, raising capital and developing its product candidates.

The Company is subject to risks common in the biotechnology industry including, but not limited to, raising additional capital, development by its
competitors of new technological innovations, its ability to successfully complete preclinical and clinical development of product candidates and receive
timely regulatory approval of products, market acceptance of the Company’s products, protection of proprietary technology, healthcare cost containment
initiatives, and compliance with governmental regulations, including those of the U.S. Food and Drug Administration (“FDA”). Additionally, the Company
is subject to risks arising from the Coronavirus Disease 2019 (COVID-19) pandemic, which could have adverse effects upon its business and operations,
including on its ability to initiate, conduct and complete clinical trials, and could disrupt regulatory activities.

Collaboration and License Agreement

On October 27, 2020, the Company and its wholly-owned subsidiaries Apellis Switzerland GmbH and APL DEL Holdings, LLC entered into a

Collaboration and License Agreement with Sobi, concerning the development and commercialization of pegcetacoplan and specified other structurally and
functionally similar compstatin analogues or derivatives for use systemically or for local non-ophthalmological administration (collectively referred to as
the “Licensed Products”).

Under the collaboration agreement, the Company granted Sobi an exclusive (subject to certain retained rights of the Company), sublicensable
license of certain patent rights and know-how to develop and commercialize Licensed Products in all countries outside of the United States. The Company
retained the right to commercialize Licensed Products in the United States, and, subject to specified limitations, to develop Licensed Products worldwide
for commercialization in the United States.  

Sobi paid the Company an upfront payment of $250.0 million in November 2020 and has agreed to pay up to an aggregate of $915.0 million upon

the achievement of specified one-time regulatory and commercial milestone events, and to reimburse the Company for up to $80.0 million in development
costs. The Company will also be entitled to receive tiered, double-digit royalties (ranging from high teens to high twenties) on sales of Licensed Products
outside of the United States, subject to customary deductions and third-party payment obligations, until the latest to occur of:  (i) expiration of the last-to-
expire of specified licensed patent rights; (ii) expiration of regulatory exclusivity; and (iii) ten (10) years after the first commercial sale of the applicable
Licensed Product, in each case on a Licensed Product-by-Licensed Product and country-by-country basis.  Under the collaboration agreement, the
Company remains responsible for its license fee obligations (including royalty obligations) to the University of Pennsylvania as a licensor of the Company
and for its payment obligations to SFJ Pharmaceuticals. See note 11, License and Collaboration Agreements, for further discussion related to the Sobi
collaboration agreement.

Convertible Notes Offering

On May 12, 2020, the Company completed a private offering of $300.0 million aggregate principal amount of 3.5% convertible senior notes due
2026 (the “2020 Convertible Notes”). The aggregate purchase price of the 2020 Convertible Notes was $328.9 million, which amount includes accrued
interest from March 15, 2020 to, but not including, May 12, 2020.

The net proceeds from the sale of the Convertible Notes were approximately $322.9 million after deducting the initial purchasers’ discounts and

commissions and offering expenses paid by the company. The Company used $43.1 million of the net proceeds from the sale of the Convertible Notes to
pay the cost of the capped call transactions described below.

The 2020 Convertible Notes form a single series with, and have the same terms as, the Company’s $220.0 million aggregate principal amount of

3.500% convertible senior notes due 2026 issued on September 16, 2019, (the “2019 Convertible Notes”, and together with the 2020 Convertible Notes, the
“Convertible Notes”), but have a different issue date, issue price, CUSIP number and different restrictions on transfer. The 2020 Convertible Notes were
issued as additional notes under the indenture (the “Indenture”), dated as of September 16, 2019, by and between the Company and U.S. Bank National
Association, as trustee (the “Trustee”), under which the 2019 Convertible Notes were issued. The 2020 Convertible Notes rank equal in right of payment to
the 2019 Convertible Notes.

113

 
 
The 2020 Convertible Notes are senior unsecured obligations of the Company and bear interest at a rate of 3.5% per year payable semiannually in

arrears on March 15 and September 15 of each year, beginning on March 15, 2020. The Convertible Notes will mature on September 15, 2026, unless
converted earlier, redeemed or repurchased in accordance with the terms of the Convertible Notes. See Note 6 – Long-term Debt for additional information.

Subsequent to year end, on January 6, 2021, the Company entered into separate, privately negotiated exchange agreements with certain holders of its

2019 Convertible Notes.  Under the terms of these exchange agreements, the holders exchanged approximately $126.1 million in aggregate principal
amount of 2019 Convertible Notes held by them for an aggregate of 3,906,869 shares of common stock. The exchange transactions closed on January 26,
2021. As of the date of this Annual Report on Form 10-K, the Company holds the $126.1 million principal amounts of exchanged notes and such notes
have not been cancelled.

Capped Call Transactions

On May 6, 2020, concurrently with the pricing of the 2020 Convertible Notes, the Company entered into capped call transactions with two

counterparties. The capped call transactions are expected generally to reduce the potential dilution to the Company’s common stock upon any conversion of
the 2020 Convertible Notes and/or offset any cash payments the Company is required to make in excess of the principal amount of converted 2020
Convertible Notes, as the case may be, in the event that the market price per share of the Company’s common stock, as measured under the terms of the
capped call transactions, is greater than the strike price of the capped call transactions, which is initially $39.4625 (the conversion price of the 2020
Convertible Notes) and is subject to anti-dilution adjustments substantially similar to those applicable to the conversion rate of such 2020 Convertible
Notes.

Follow-on Public Offerings

On January 13, 2020, the Company issued and sold 10,925,000 shares of its common stock at a price per share to the public of $37.00 in a follow-on

public offering including an additional 1,425,000 shares of its common stock that were sold at the follow-on public offering price of $37.00 per share
pursuant to the underwriters’ in full exercise of their option to purchase additional shares of common stock. The Company received net proceeds of
approximately $381.4 million after deducting underwriting discounts and commissions of approximately $22.2 million and offering costs of $0.5 million
for these transactions.  

On March 11, 2019, the Company issued and sold 6,900,000 shares of its common stock at a price per share of $17.00 in a follow-on public
offering. The Company received net proceeds of approximately $109.6 million after deducting underwriting discounts and commissions of approximately
$7.0 million and offering costs of $0.7 million.  

Liquidity and Going Concern

The accompanying consolidated financial statements have been prepared on the basis of the realization of assets and the satisfaction of liabilities and

commitments in the normal course of business.  As of February 25, 2021, the date of issuance of these consolidated financial statements, the Company
believes that its cash and cash equivalents and marketable securities as of December 31, 2020 of $877.6 million, will be sufficient to fund its operations and
capital expenditures for at least the next twelve months from the date of issuance of these consolidated financial statements. The Company’s future viability
beyond that point is dependent on its ability to raise additional capital to finance its operations.

The Company is subject to risks common to other life science companies in the development stage including, but not limited to, uncertainty of

product development and commercialization, lack of marketing and sales history, development by its competitors of new technological innovations,
dependence on key personnel, market acceptance of products, product liability, protection of proprietary technology, ability to raise additional financing,
and compliance with FDA and other government regulations. If the Company does not successfully commercialize any of its product candidates, it will be
unable to generate recurring product revenue or achieve profitability. Management’s plans in order to meet its short-term and longer-term operating cash
flow requirements include obtaining additional funding.

There are uncertainties associated with the Company’s ability to (1) obtain additional debt or equity financing on terms that are favorable to the

Company, (2) enter into collaborative agreements with strategic partners, and (3) succeed in its future operations. If the Company is not able to obtain the
required funding for its operations, or is not able to obtain funding on terms that are favorable to the Company, it could be forced to delay, reduce or
eliminate its research and development programs or future commercialization efforts and its business could be materially harmed.

2. Summary of Significant Accounting Policies

Basis of Presentation

The accompanying consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries, Apellis Australia Pty

Ltd, Apellis Bermuda Limited, Apellis Germany GmbH, Apellis Ireland Ltd, Apellis Netherlands B.V., Apellis Switzerland GmbH, Apellis UK Limited,
APL DEL Holdings LLC, APL Sales Corp I, LLC, APL PRG I, Corp. and Apellis MA Securities Corp. All intercompany balances and transactions have
been eliminated in consolidation. The consolidated financial statements have been prepared in conformity with accounting principles generally accepted in
the United States of America (“U.S. GAAP”) and following the requirements of the Securities and Exchange Commission (the “SEC”).

Licensing and Collaboration Revenue

The Company analyzes license and collaboration arrangements pursuant to FASB ASC Topic 808, Collaborative Arrangement Guidance and

Considerations, (“ASC 808”) to assess whether such arrangements, or transactions between arrangement participants, involve joint operating activities
performed by parties that are both active participants in the activities and exposed to significant risks and rewards dependent on the commercial success of
such activities or are more akin to a vendor-customer relationship. In making this evaluation, the Company considers whether the activities of the
collaboration are considered to be distinct and deemed to be within the scope of the collaborative arrangement guidance or if they are more reflective of a
vendor-customer relationship and, therefore, within the scope of FASB ASC Topic 606, Revenue from Contracts with Customer, (“ASC 606”). This
assessment is performed throughout the life of the arrangement based on changes in the responsibilities of all parties in the arrangement.

For elements of collaboration arrangements that are not accounted for pursuant to guidance in ASC 606, an appropriate recognition method is
determined and applied consistently, generally by analogy to the revenue from contracts with customers guidance. Amounts related to transactions with a
counterparty in a collaborative arrangement that is not a customer are presented as collaboration revenue and in a separate line item from revenue
recognized from contracts with customers, if any, in our consolidated statements of operations.

Pursuant to ASC 606, for arrangements or transactions between arrangement participants determined to be within the scope of the contracts with

customers guidance, the Company performs the following steps to determine the appropriate amount of revenue to be recognized as we fulfill our
obligations: (i) identification of the promised goods or services in the contract; (ii) determination of whether the promised goods or services are
performance obligations including whether they are distinct in the context of the contract; (iii) measurement of the transaction price, including the
constraint on variable consideration; (iv) allocation of the transaction price to the performance obligations based on estimated selling prices; and (v)
recognition of revenue when (or as) the Company satisfies each performance obligation.

We evaluate the performance obligations promised in the contract that are based on goods and services that will be transferred to the customer and
determine whether those obligations are both (i) capable of being distinct and (ii) distinct in the context of the contract. Goods or services that meet these
criteria are considered distinct performance obligations. The Company estimates the transaction price based on the amount expected to be received for
transferring the promised goods or services in the contract. The consideration may include fixed consideration or variable consideration. At the inception of
each arrangement that includes variable consideration, the Company evaluates the amount of potential transaction price and the likelihood that the
transaction price will be received. The Company utilizes either the most likely amount method or expected value method to estimate the amount expected
to be received based on which method best predicts the amount expected to be received. The amount of variable consideration that is included in the
transaction price may be constrained and is included in the transaction price only to the extent that it is probable that a significant reversal in the amount of
the cumulative revenue recognized will not occur in a future period. Arrangements that include rights to additional goods or services that are exercisable at
a customer’s discretion are generally considered options.  We assess if these options provide a material right to the customer and, if so, these options are
considered performance obligations. The Company has not currently identified any such material rights.

Revenue is recognized when, or as, the Company satisfies a performance obligation by transferring a promised good or service to a customer. An

asset is transferred when, or as, the customer obtains control of that asset. For performance obligations that are satisfied over time, the Company recognizes
revenue using an input or output measure of progress that best depicts the satisfaction of the relevant performance obligation.

After contract inception, the transaction price is reassessed at every period end and updated for changes such as resolution of uncertain events. Any

change in the overall transaction price is allocated to the performance obligations on the same methodology as at contract inception.

Offering Costs

Offering costs represent underwriting, legal, accounting and other direct costs related to the Company’s follow-on offerings and filing of a

registration statements on Form S-3 in 2019, and related to the Company’s offering of Convertible Notes in 2020 and 2019. Costs were deferred until
completion of the follow-on offerings and offering of Convertible Notes, at which time they were reclassified to additional paid-in capital as a reduction of
the proceeds.  

Segment Information

Operating segments are defined as components of an enterprise about which separate discrete information is available for evaluation by the chief

operating decision maker, or decision-making group, in deciding how to allocate resources and in assessing performance. The Company views its
operations and manages its business in one operating segment.    

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the

reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts
of revenues and expenses during the reporting period. Actual results may differ from those estimates. Management considers many factors in selecting
appropriate financial accounting policies and controls, and in developing the estimates and assumptions that are used in the preparation of these financial
statements. Management must apply significant judgment in this process. In addition, other factors may affect estimates, including expected business and
operational changes, sensitivity and volatility associated with the assumptions used in developing estimates, and whether historical trends are expected to
be representative of future trends. The estimation process often may yield a range of potentially reasonable estimates of the ultimate future outcomes, and
management must select an amount that falls within that range of reasonable estimates. Estimates are used in the following areas, among others:
development derivative liability, accrued expenses, prepaid expenses, convertible debt and taxes.

Fair Value of Financial Instruments

The Company is required to disclose information on the fair value of financial instruments and inputs that enable an assessment of the fair value.

The three levels of the fair value hierarchy prioritize valuation inputs based upon the observable nature of those inputs as follows:

Level 1 – Quoted prices in active markets for identical assets or liabilities;

Level 2 – Inputs other than quoted prices included within level 1 that are observable for the asset or liability, either directly or indirectly;

Level 3 – Unobservable inputs that reflect the Company’s own assumptions about the assumptions market participants would use in pricing the

asset or liability.  

The Company’s financial instruments, in addition to those presented in Note 6, Long-term Debt, Note 8, Marketable Securities, and Note 10, Fair

Value Measurements, include cash and cash equivalents, the Australian research and development credit, accounts payable and accrued liabilities.
Management believes that the carrying amounts of cash and cash equivalents, the Australian research and development credit, accounts payable and
accrued expenses approximate the fair value due to the short-term nature of those instruments.

Cash and Cash Equivalents

Cash and cash equivalents are defined as cash in banks and investment instruments having maturities of three months or less from their acquisition
date. The carrying amounts reported in the consolidated balance sheets for cash and cash equivalents are valued at cost, which approximates the fair value.
See Note 10, Fair Value Measurements, for additional information.

Foreign Currency

The financial position and results of operations of the Company's Australian, Irish and German subsidiaries are measured using the foreign

subsidiary's local currency. Revenues and expenses of the subsidiaries have been translated into U.S. dollars at average

116

 
exchange rates prevailing during the respective periods. Assets and liabilities have been translated at the rates of exchange on the balance sheet date. The
resulting translation gain and loss adjustments are recorded directly as a separate component of stockholders’ equity. The financial position and results of
operations of the Company’s Swiss subsidiary are measured and reported in U.S. dollars and transactions are translated to U.S. dollars at the end of the
period.

Research and Development

Costs incurred in connection with research and development activities are expensed as incurred. Research and development expenses include
(i) employee-related expenses, including salaries, benefits, travel and share-based compensation expense; (ii) external research and development expenses
incurred under arrangements with third parties, such as contract research and contract manufacturing organizations, investigational sites and consultants,
including share-based compensation expense for consultants; (iii) the cost of acquiring, developing and manufacturing clinical study materials; and
(iv) costs associated with preclinical and clinical activities and regulatory operations.

The Company enters into consulting, research and other agreements with commercial entities, researchers, universities and others for the provision
of goods and services. Such arrangements are generally cancellable upon reasonable notice and payment of costs incurred. Costs are considered incurred
based on an evaluation of the progress to completion of specific tasks under each contract using information and data provided by the Company’s clinical
sites and vendors. These costs consist of direct and indirect costs associated with specific projects, as well as fees paid to various entities that perform
certain research on behalf of the Company.

Depending upon the timing of payments to the service providers, the Company recognizes prepaid expenses or accrued expenses related to these

costs. These accrued or prepaid expenses are based on management’s estimates of the work performed under service agreements, milestones achieved and
experience with similar contracts. The Company monitors each of these factors and adjusts estimates accordingly.

Included in research and development is a refundable Australian research and development credit. The credit is recognized as a reduction of clinical

trial costs over the periods necessary to match the benefit of the credit with the costs for which it is intended to compensate.  

Patents

Costs incurred in connection with the application for and issuance of patents are expensed as incurred.

Income Taxes

The Company recognizes deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the
financial statements or tax returns. Deferred tax assets and liabilities are determined based on the difference between the financial statement and tax bases
of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. Valuation allowances are provided if,
based upon the weight of available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized.

The Company accounts for uncertain tax positions in accordance with the provisions of ASC 740. When uncertain tax positions exist, the Company
recognizes the tax benefit of tax positions to the extent that the benefit will more likely than not be realized. The determination as to whether the tax benefit
will more likely than not be realized is based upon the technical merits of the tax position, as well as consideration of the available facts and circumstances.
As of December 31, 2020 and 2019, the Company did not have any significant uncertain tax positions.

Concentrations of Credit Risk

Cash and cash equivalents are the only financial instruments that potentially subject the Company to concentrations of credit risk. Cash and cash

equivalents are held at financial institutions in the United States, Switzerland, Australia, Ireland and Germany. The Company is exposed to credit risk in the
event of default by the financial institution to the extent that cash and cash equivalent balances recorded in the balance sheets are in excess of the amounts
that are insured by the Federal Deposit Insurance Corporation. The Company has not experienced any losses on its deposits since inception, and
management believes that minimal credit risk exists with respect to these financial institutions.

117

 
 
Net Loss per Share

Basic net loss per common share is calculated by dividing net loss by the weighted-average shares outstanding during the period. For purposes of

the diluted net loss per share calculation, convertible notes and common stock options are considered to be common stock equivalents but have been
excluded from the calculation of diluted net loss per share, as their effect would be anti-dilutive for all periods presented. Therefore, basic and diluted net
loss per share were the same for all periods presented.

Comprehensive Loss

The Company’s components of comprehensive loss other than its net loss, are the foreign currency gains/losses recorded from the remeasurement of
the long term intra-entity loan transaction to the Company’s wholly owned subsidiaries as well as the foreign currency gain/ loss from the translation of the
Company’s wholly owned subsidiaries into U.S. dollars in 2020 and 2019.    

Recent Accounting Pronouncements

In August 2020, the FASB issued ASU 2020-06, Debt – Debt with Conversion and Other Options (Subtopic 470-20) to reduce complexity in
applying GAAP to certain financial instruments with characteristics of liability and equity.  The ASU removes the guidance that requires entities to account
for beneficial conversion features and cash conversion features in equity, separately from the host convertible debt or preferred stock.  The ASU further
revises the guidance to require entities to calculate diluted earnings per share for convertible instruments by using the if-converted method.  In addition,
entities must presume share settlement for purposes of calculating diluted EPS when an instrument may be settled in cash or shares.  The new standard is
effective for annual reporting periods beginning after December 15, 2021, for public companies, including interim periods within that reporting period.
Early adoption is permitted, but no earlier than fiscal years beginning after December 15, 2020.  The Company early adopted this statement effective
January 1, 2021.  The impact of the adoption of the statement is to increase debt and decrease equity by the amount of the equity component of convertible
notes recognized in equity.  Additionally, interest expense is expected to decrease by the non-cash portion of the discount amortization. Weighted average
basic earnings per share amounts are not expected to be materially affected.

4. Development Derivative Liability

On February 28, 2019, the Company entered into the SFJ agreement under which SFJ agreed to provide funding to the Company to support the

development of pegcetacoplan for the treatment of patients with PNH. Pursuant to the agreement, SFJ paid the Company $60.0 million following the
signing of the agreement, and agreed to pay the Company up to an additional $60.0 million in the aggregate in three equal installments upon the
achievement of specified development milestones with respect to the Company’s Phase 3 program for pegcetacoplan in PNH and subject to the Company
having cash resources at the time sufficient to fund at least 10 months of the Company’s operations.

On June 7, 2019, the Company and SFJ amended the development funding agreement. Under the SFJ amendment, SFJ agreed to make an additional

$20.0 million funding payment to the Company to support the development of pegcetacoplan for the treatment of patients with PNH.

In the years ended December 31, 2020 and 2019, the Company received $20.0 million and $120.0 million, respectively, from SFJ, as the Company

met milestones as identified in the SFJ Agreement.

118

 
 
 
 
 
 
   
   
 
 
 
 
 
 
 
 
 
 
 
Under the SFJ agreement following regulatory approval by the FDA or EMA for the use of pegcetacoplan as a treatment for PNH the Company will
be obligated to pay SFJ an initial payment of up to $5.0 million (or a total of $10.0 million if regulatory approval is granted by the FDA and the EMA) and
then up to an additional $226.0 million in the aggregate (or up to $452.0 million if regulatory approval is granted by the FDA and the EMA) in six
additional annual payments with the majority of the payments being made from the third anniversary to the sixth anniversary of regulatory approval.

The SFJ agreement is presented as a derivative liability on the consolidated balance sheet and is considered a level three derivative and, as such is

remeasured each quarter. The liability was initially recorded at the value of the $60.0 million aggregate cash received pursuant to the contractual terms.
During the years ended December 31, 2020 and 2019, the Company received an additional $20.0 million and $60.0 million respectively under the SFJ
agreement as the Company met additional milestones in the agreement. The derivative liability was remeasured quarterly at fair value, with the total change
in fair value of $103.0 million and $14.8 million recorded for the years ended December 31, 2020 and 2019, respectively in loss from remeasurement of
development derivative liability on the consolidated income statement. The remeasurement of the development derivative liability resulted in a remeasured
fair value of $257.9 million and $134.8 million as of December 31, 2020 and 2019, respectively on the consolidated balance sheet.  At December 31, 2020,
$4.2 million of the $257.9 million of the development derivative liability fair market value is included in current liabilities.  

The following table presents a rollforward of the liability (in thousands):

The derivative is valued using a scenario-based discounted cash flow method, whereby each scenario makes assumptions about the probability and

timing of cash flows, and such cash flows are present valued using a risk-adjusted discount rate. The analysis is calibrated such that the value of the
derivative as of the date of the SFJ agreement was consistent with an arm’s-length transaction. Key inputs to the level 3 fair value model include (i) the
probability and timing of achieving stated development milestones to receive the next tranches of funding, (ii) the probability and timing of achieving FDA
and EMA approval, (iii) SFJ’s cost of borrowing (8.0%), and (iv) the Company’s cost of borrowing (12.65%).

SFJ’s implied cost of borrowing was 8.0% and the Company’s implied cost of borrowing was 12.65% as of the reporting date. These implied costs

of borrowing were determined assuming the SFJ agreement was initially executed with arm’s-length terms. If the SFJ agreement was instead not
determined to be an arm’s-length transaction, then implied discount rates could differ.

6. Long-term Debt

Convertible Senior Notes

On September 16, 2019, the Company completed a private offering of the 2019 Convertible Notes with an aggregate principal amount of $220.0

million issued pursuant to an indenture (the “Indenture”) with U.S. Bank National Association, as trustee (the “Trustee”).

The net proceeds from the sale of the 2019 Convertible Notes were approximately $212.9 million after deducting the initial purchasers’ discounts
and commissions of $6.6 million and offering expenses of $0.5 million paid by the Company. The Company used $28.4 million of the net proceeds from
the sale of the Convertible Notes to pay the cost of the capped call transactions described below.

On May 12, 2020, the Company issued the 2020 Convertible Notes with an aggregate principal amount of $300.0 million. The net proceeds from the

sale of the 2020 Convertible Notes were approximately $322.9 million after deducting the purchasers’ discounts and commission of $5.7 million and
offering expenses of $0.3 million. The Company used $43.1 million of the net proceeds from the sale to pay the cost of the additional capped call
transactions in May 2020 described below.

The Convertible Notes are senior unsecured obligations of the Company and bear interest at a rate of 3.5% per year payable semiannually in arrears

on March 15 and September 15 of each year, beginning on March 15, 2020. The Convertible Notes will mature on September 15, 2026, unless converted
earlier, redeemed or repurchased in accordance with the terms of the Convertible Notes.

The Convertible Notes are convertible into shares of the Company’s common stock at an initial conversion rate of 25.3405 shares per $1,000
principal amount of Convertible Notes (equivalent to an initial conversion price of approximately $39.4625 per share of common stock). The conversion
rate is subject to customary anti-dilution adjustments. In addition, following certain events that occur prior to the maturity date or if the Company deliver a
notice of redemption, the Company will increase the conversion rate for a holder who elects to convert its Convertible Notes in connection with such
corporate event or a notice of redemption, as the case may be, in certain circumstances as provided in the indenture.

Prior to March 15, 2026, the Convertible Notes are convertible only upon the occurrence of certain events. On or after March 15, 2026 until the

close of business on the second scheduled trading day immediately preceding the maturity date of the Convertible Notes, holders may convert the
Convertible Notes at any time. Upon conversion of the Convertible Notes, the Company will pay or deliver, as the case may be, cash, shares of the
Company’s common stock or a combination of cash and shares of common stock, at the Company’s election.

Prior to September 20, 2023, the Company may not redeem the Convertible Notes. The Company may redeem for cash all or a portion of the

Convertible Notes, at its option, on or after September 20, 2023 if the last reported sale price of the Company’s common stock has been at least 130% of
the conversion price then in effect for at least 20 trading days (whether or not consecutive), including the trading day immediately preceding the date on
which the Company provides a notice of redemption, during any 30 consecutive trading day period ending on, and including, the trading day immediately
preceding the date on which the Company provides notice of redemption. The redemption price will be equal to 100% of the principal amount of the
Convertible Notes to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date.

If the Company undergoes a “fundamental change,” as defined in the Indenture, prior to maturity, subject to certain conditions, holders may require
the Company to repurchase for cash all or any portion of their Convertible Notes at a fundamental change repurchase price equal to 100% of the principal
amount of the notes to be repurchased, plus any accrued and unpaid interest to, but excluding, the fundamental change repurchase date.

The Company used an effective interest rate of 10.5% to determine the liability component of the 2019 and 2020 Convertible Notes. This resulted in

the recognition of $145.1 million and $204.5 million as the liability component of the 2019 and 2020 Convertible Notes, respectively, and the recognition
of the residual amount of $74.9 million and $95.5 million as the debt discount with a corresponding increase to additional paid in capital for the equity
component of the 2019 and 2020 Convertible Notes, respectively. The 2020 aggregate debt issuance costs of $6.0 million were allocated to the liability and
equity components in the amounts of $3.7 million and $2.3 million, respectively.  The 2019 Convertible Notes aggregate debt issuance costs of $7.1 million
were allocated to the liability and equity components in the amounts of $4.7 million and $2.4 million, respectively.  

Interest expense for the Convertible Notes was $29.9 million for the year ended December 31, 2020 and $4.4 million from inception through
December 31, 2019.  For the year ended December 31, 2020, interest expense included the amortization of the discount on the Convertible Notes of $15.0
million, accrued semi-annual coupon payable of $14.4 million and amortization of debt issuance costs of $0.5 million. From inception through December
31, 2019, interest expense included amortization of the discount on

120

 
the Convertible Notes of $2.1 million, accrued semi-annual coupon payable of $2.2 million and amortization of debt issuance costs of $0.1 million. As of
December 31, 2020 and 2019, $7.8 million and $4.6 million, respectively of debt issuance costs was recorded on the consolidated balance sheet as a
reduction to the carrying amount of the Convertible Notes.

The aggregate balance of the Convertible Notes, net of unamortized debt issuance costs, as of December 31, 2020 and 2019 was $358.8 million and

$142.6 million, respectively.  See note 20 “Subsequent events” for discussion on the exchange of $126.1 million of 2019 Convertible Notes to shares of
common stock.

Capped Call Transactions

On September 11, 2019, and May 6, 2020 concurrently with the pricing of the 2019 Convertible Notes and the 2020 Convertible Notes, the
Company entered into capped call transactions with two counterparties. The capped call transactions are expected generally to reduce the potential dilution
to the Company’s common stock upon any conversion of Convertible Notes and/or offset any cash payments the Company is required to make in excess of
the principal amount of converted Convertible Notes, as the case may be, in the event that the market price per share of the Company’s common stock, as
measured under the terms of the capped call transactions, is greater than the strike price of the capped call transactions, which is initially $39.4625 (the
conversion price of the Convertible Notes) and is subject to anti-dilution adjustments substantially similar to those applicable to the conversion rate of such
Convertible Notes. If, however, the market price per share of the Company’s common stock, as measured under the terms of the capped call transactions,
exceeds the cap price of the capped call transactions, which is initially $63.14 per share, representing a premium of 100% above the last reported sale price
of $31.57 per share of its common stock on The Nasdaq Global Select Market on September 11, 2019, there would nevertheless be dilution and/or there
would not be an offset of such potential cash payments, in each case, to the extent that such market price exceeds the cap price of the capped call
transactions.

Pursuant to ASC 815-40 Derivatives and Hedging, the Company determined that the capped call transactions should be classified as equity
instruments and the capped call premium paid in the amount of $28.4 million and $43.1 million were recorded as reductions to additional paid-in capital
upon the issuance of the Convertible Notes.

Term Loan Facility

On October 20, 2017, the Company entered into a loan and security agreement with Silicon Valley Bank (“SVB”) to provide for a $20.0 million
term loan facility (the “term loan facility”). Borrowings under the term loan facility accrued interest at a floating rate per annum equal to the WSJ prime
rate plus 1.50%. Under the agreement, the Company was required to make monthly interest-only payments through November 1, 2019 and to make 24
equal monthly payments of principal, plus accrued interest, thereafter from November 1, 2019 through October 1, 2021, when all unpaid principal and
interest would become due and payable.

On March 26, 2019, the Company voluntarily repaid all outstanding amounts due and owed, including applicable termination fees, under the term

loan facility. The final payment of $21.8 million totaled per diem interest of $0.1 million and $21.7 million for the outstanding balance of the term loan
facility which included (i) a final payment equal to 8% of the original principal amount of the term loan facility of $1.6 million, and (ii) a prepayment fee
contractually owed of $0.1 million plus other fees which resulted in a total loss on extinguishment of debt of $1.2 million.                

In connection with the Company’s entry into the term loan facility, the Company issued to SVB a warrant to purchase 14,064 shares of the
Company’s common stock with an exercise price per share of $5.484. The warrant had a ten-year term and included a put option pursuant to which, in the
event of an acquisition, change in control or dissolution or winding up of the Company or the expiration of the warrant, SVB could require the Company to
repurchase the warrant for a total aggregate purchase price of $250 thousand. The warrants were exercised in November 2019.

Promissory Note

On October 19, 2017, the Company issued and sold an unsecured promissory note in the principal amount of $7.0 million to Golda Darty Partners

S.A. (“GDP”). The promissory note accrued interest at a rate per annum of 8.0%, and was due and payable quarterly in arrears on the 19th day of each
April, July, October and January. The promissory note had a maturity date of October 19, 2022 when the $7.0 million would be due and payable in its
entirety. The promissory note was contractually subordinated to the Company’s obligations to SFJ under the SFJ agreement.

On September 16, 2019, the Company voluntarily repaid all outstanding amounts due and owed under the promissory note, except for a small

amount of interest subsequently repaid. The payment of $7.1 million reflected per diem interest of $0.1 million and $7.0 million for the outstanding
principal balance of the promissory note.

In connection with the issuance and sale of the above promissory note, the Company issued to GDP a warrant to purchase 93,764 shares of the

Company’s common stock at a price per share of $5.484, which was exercised in whole in October 2017. The

121

 
Company recorded the fair value of the warrant in the aggregate amount of $0.4 million as a discount to the promissory note. This amount was being
accreted as additional interest expense over the term of the promissory note. Upon the repayment of the promissory note, the Company recorded a loss on
extinguishment of debt of $0.3 million due to the remaining discount.

The contractual maturities of the Company’s long-term debt obligations due subsequent to December 31, 2020 consist of the $520.0 Convertible

Senior Notes which mature in September 2026.

7. Leases

On January 1, 2019, the Company adopted ASU 2016-02 Leases (Topic 842) using a modified retrospective method. The Company recognized $5.5
million of lease assets and liabilities. There was no impact to retained earnings upon adoption of Topic 842.  The underlying assets of the Company’s leases
primarily relate to office space leases, but also include some equipment leases. The Company determines if an arrangement qualifies as a lease at its
inception. During 2019, the Company leased additional office space resulting in an initial recognition value of $9.8 million of lease assets and liabilities.  

As a practical expedient permitted under Topic 842, the Company has elected to account for the lease and non-lease components as a single lease

component for all leases of which it is the lessee. Lease payments, which may include lease and non-lease components, are included in the measurement of
the Company’s lease liabilities to the extent that such payments are either fixed amounts or variable amounts that depend on a rate or index as stipulated in
the lease contract. When the Company cannot readily determine the rate implicit in the lease, the Company determines its incremental borrowing rate by
using the rate of interest that it would have to pay to borrow on a collateralized basis over a similar term, an amount equal to the lease payments in a similar
economic environment.

The Company enters into lease agreements with terms generally ranging from 2-7 years. Some of the Company’s lease agreements include
Company options to extend the lease on a month-to-month basis or for set periods for up to five years. Many leases also include options to terminate the
leases within one year or per other contractual terms. Renewal and termination options were generally not included in the lease term for the Company’s
existing operating leases.

As of December 31, 2020 and 2019, all leases were classified as operating lease assets and liabilities. Additional information related to the operating

lease assets and liabilities is as follows (in thousands):

The Company is required to disclose information on the fair value of financial instruments and inputs that enable an assessment of the fair

value. The three levels of the fair value hierarchy prioritize valuation inputs based upon the observable nature of those inputs as follows:

Level 2 – Inputs other than quoted prices included within level 1 that are observable for the asset or liability, either directly or indirectly;

Level 3 – Unobservable inputs that reflect the Company’s own assumptions about the assumptions market participants would use in pricing the

asset or liability.

The Company’s Convertible Notes fall into the Level 2 category within the fair value level hierarchy.  The fair value was determined using broker

quotes in a non-active market for valuation.  As of December 31, 2020 and 2019, the debt component of the Company’s Convertible Notes had a fair value
of approximately $676.2 million and $149.5 million, respectively. The Convertible Notes accrue a semi-annual coupon at an annual rate of 3.5%, which
was included in accrued expenses in the consolidated balance sheet at December 31, 2020 and 2019.

The fair value of the SFJ agreement is presented as a development derivative liability based on level 3 inputs. The derivative is valued using a

scenario-based discounted cash flow method, whereby each scenario makes assumptions about the probability and timing of cash flows, and such cash
flows are present valued using a risk-adjusted discount rate. The analysis is calibrated such that the value of the derivative as of the date of the SFJ
agreement was consistent with an arm’s-length transaction. Key inputs to the level 3 fair value model include (i) the probability and timing of achieving
stated development milestones to receive the next tranches of

funding, (ii) the probability and timing of achieving FDA and EMA approval, (iii) SFJ’s cost of borrowing (8.0%), and (iv) the Company’s cost of
borrowing (12.65%). A 10% change in the key inputs of i) the probability and timing of payment and ii) the discount rate utilized would result in a change
in fair value of the development derivative liability of approximately 5.0% or $12.9 million.

SFJ’s implied cost of borrowing was 8.0% and the Company’s implied cost of borrowing was 12.65% as of the reporting date. These implied costs

of borrowing were determined assuming the SFJ agreement was initially executed with arm’s-length terms.

11. License and Collaboration Agreements

Sobi Transaction

On October 27, 2020, the Company and its subsidiaries Apellis Switzerland GmbH and APL DEL Holdings, LLC entered into a Collaboration and

License Agreement with Sobi, concerning the development and commercialization of pegcetacoplan and specified other structurally and functionally
similar compstatin analogues or derivatives for use systemically or for local non-ophthalmological administration (collectively referred to as the “Licensed
Products”).

Under the collaboration agreement, the Company granted Sobi an exclusive (subject to certain retained rights of the Company), sublicensable
license of certain patent rights and know-how to develop and commercialize Licensed Products in all countries outside of the United States.  The Company
retains the right to commercialize Licensed Products in the United States, and, subject to specified limitations, to develop Licensed Products worldwide for
commercialization in the United States.  

Under the collaboration agreement, the Company and Sobi have agreed to collaborate to develop Licensed Products for the treatment of  paroxysmal
nocturnal hemoglobinuria, cold agglutinin disease, hematopoietic stem cell transplantation-associated thrombotic microangiopathy, C3 glomerulopathy and
immune complex membranoproliferative glomerulonephritis, and amyotrophic lateral sclerosis, and any other indications subsequently agreed upon by the
parties, for commercialization by or on behalf of the Company in the United States and by or on behalf of Sobi outside of the United States. If the parties
do not agree to jointly pursue any development activities for the Licensed Products (whether for an Initial Indication or otherwise), the party proposing to
pursue such activities may conduct such activities at its sole expense (with the non-proposing party having the right to obtain rights to the data generated by
such development activities by paying a specified percentage of that expense), subject to agreed-upon exceptions that limit each party’s unilateral
development rights.

The initial development plan sets forth the initial development activities to be conducted by each of the Company and Sobi, with the Company
bearing all costs incurred in conducting the activities set forth in such initial development plan, as well as certain specified additional costs that are not
included in the initial development plan that may be incurred by the parties in developing Licensed Products for paroxysmal nocturnal hemoglobinuria in
the European Union and the United Kingdom. The Company and Sobi will form several governance committees to oversee the development and
manufacture, and to review and discuss the commercialization, of Licensed Products.

The Company shall supply Licensed Products to Sobi for development and for commercialization outside of the United States in accordance with a

supply agreement to be negotiated by the parties.  The collaboration agreement grants Sobi the right to perform or have performed drug product
manufacturing of Licensed Products for development and for commercialization outside the United States and to manufacture or have manufactured drug
substance under certain circumstances.

Sobi paid the Company an upfront payment of $250.0 million in November 2020 and has agreed to pay up to an aggregate of $915.0 million upon

the achievement of specified one-time regulatory and commercial milestone events, and to reimburse the Company for up to $80.0 million in development
costs. The Company will also be entitled to receive tiered, double-digit royalties (ranging from high teens to high twenties) on sales of Licensed Products
outside of the United States, subject to customary deductions and third-party payment obligations, until the latest to occur of:  (i) expiration of the last-to-
expire of specified licensed patent rights; (ii) expiration of regulatory exclusivity; and (iii) ten (10) years after the first commercial sale of the applicable
Licensed Product, in each case on a Licensed Product-by-Licensed Product and country-by-country basis.  Under the collaboration agreement, the
Company remains responsible for its license fee obligations (including royalty obligations) to the University of Pennsylvania as a licensor of the Company
and for its payment obligations to SFJ Pharmaceuticals.

Accounting Analysis

The Company has determined that the agreement is within the scope of ASC 808 as a contractual arrangement that involves a joint operating activity
whereby both parties are (i) active participants in the activity and (ii) exposed to certain significant risks and rewards dependent on the commercial success
of the activity.  ASC Topic 808 does not address measurement or recognition matters

125

 
 
but allows for analogizing to ASC 606.  Pursuant to ASC 606, the Company performed the following five steps: (i) identified the contract(s) with a
customer; (ii) identified the performance obligations in the contract; (iii) determined the transaction price; (iv) allocated the transaction price to the
performance obligations in the contract; and (v) recognized revenue when (or as) the entity satisfies a performance obligation.  

The Company identified the following material distinct promises under the Sobi Agreement: (1) licenses to develop and commercialize

pegcetacoplan or, Licenses to IP, and (2) performance of research and development services. The Company determined the promises to be distinct because
Sobi can benefit from each of the license and the development services on their own or with readily available services.  The Company could have provided
the license without any development services and Sobi would have been able to benefit from it by obtaining development services from another provider as
the Licensed Products are at a more mature stage in their life cycle.   

Under the agreement, Sobi agreed to pay the Company
i)
ii)

a fixed amount of $250.0 million in an upfront payment in November 2020;
a fixed amount of an additional $80.0 million in development reimbursements, payable yearly in four tranches in amounts determined
based upon actual expenses incurred by the Company;     
up to an aggregate of $915.0 million upon the achievement of specified one-time regulatory and commercial milestone events; and
tiered, double-digit royalties, ranging from high teens to high twenties, on sales of Licensed Products outside of the United States, subject
to customary deductions and third-party payment obligations.  

iii)
iv)

At contract inception, the $250.0 million non-refundable payment and the $80.0 million reimbursements were fixed proceeds.  The Company
evaluated whether Sobi is a customer for either of the distinct promises in the agreement. Under the Licenses to IP, the Company determined that Sobi is a
customer as the know-how provided and the right granted by the Company to Sobi are outputs of the Company’s business activities for which the Company
will receive consideration. With respect to research and development activity, management determined that there is no vendor relationship as performing
research and development activities for others is not a part of the Company’s ongoing central operations. Based upon the evaluation of the relative fair
values, the Company allocated the purchase price of $250.0 million and the related milestones and royalties to the license of IP and $80.0 million to
performance of research and development activities.

The milestone and royalty payments are subject to activities outside the control of the Company. Per ASC 606, the Company considers this to be a

customer/ vendor relationship, therefore, the Company will include the regulatory milestone payments in the total transaction price when it is probable that
a significant reversal of revenue would not occur in a future period. The Company will recognize commercial milestone and royalty revenue at the later of
(i) when the related sales occur or (ii) when the performance obligation to which the commercial milestone or royalty has been allocated has been satisfied.
In case of commercial milestone or royalty payments, the Company will recognize revenue in the same period that the sales are completed for which the
Company is contractually entitled to the milestone or percentage-based royalty payment. To date, the Company has not recognized any commercial
milestone or royalty revenue resulting from any of our licensing arrangements.  Management will periodically assess the elements of the contract and re-
evaluate revenue recognition as necessary.

Pursuant to ASC 606, the Company has recognized the $250.0 million in revenue as this is the amount allocated to the license.  The $80.0 million

reimbursement for research and development activities does not constitute a customer/vendor relationship and thus is not in the scope of ASC 606. As ASC
808 does not include recognition guidance, the Company has established an accounting policy to recognize the payments under the reimbursement as a
receivable on the balance sheet in an amount that is to be reimbursed based upon expense incurred by the Company, with a contra- research and
development expense recognized in the statement of operations, over time as the expenses are incurred.

Under the Sobi collaboration agreement, for the year ended December 31, 2020, the Company recognized $250.0 million of licensing revenue in the

consolidated statement of operations.  For the year ended December 31, 2020, the Company also recognized in the consolidated statement of operations
$43.0 million of contra research and development expense relative to the probable amount to be reimbursed under the $80.0 million for research and
development. The Company recorded a corresponding receivable of $43.0 million on the consolidated balance sheet, with $25.0 million and $18.0 million
in current and long-term assets, respectively, as of December 31, 2020.

126

 
 
 
 
 
Other agreements

In addition, to the Sobi collaboration agreement, during the year ended December 31, 2020, we entered into two different agreements with third

parties to provide APL-9 for use in certain research projects for which $0.6 million was recognized in revenue in the consolidated statement of operations
as of December 31, 2020.  

12. License Agreements

In connection with its purchase of assets from Potentia in September 2014, the Company became party to a license agreement with the Trustees of

the University of Pennsylvania (“Penn”) as a result of an agreement to purchase substantially all the assets of Potentia Pharmaceuticals, Inc, for an
exclusive, worldwide license to specified patent rights. The Company is required to pay annual maintenance fees of $0.1 million until the first sale of a
licensed product. The Company is also required to make milestone payments aggregating up to $3.2 million based upon the achievement of specified
development and regulatory milestones and up to $5.0 million based upon the achievement of specified annual sales milestones with respect to each
licensed product, and to pay low single-digit royalties based on net sales of each licensed product and with minimum quarterly royalty thresholds. In
addition, the Company is obligated to pay a specified portion of income it receives from sublicensees.

In addition, the Company is also party to a license agreement with Penn for an exclusive, worldwide license to specified patent rights for the

development and commercialization of products in fields of use, as defined therein. The Company is required to pay annual maintenance fees of $0.1
million until the first sale of a licensed product. The Company is required to make milestone payments aggregating up to $1.7 million, based upon the
achievement of development and regulatory approval milestones, and up to $2.5 million, based upon the achievement of annual sales milestones with
respect to each of the first two licensed products. The license agreement also requires the Company to pay low single digit royalties based on net sales of
each licensed product, subject to minimum quarterly royalty thresholds. In addition, the Company is obligated to pay a specified portion of income it
receives from sublicensees.

In 2018, the Company made payments to Penn of $1.0 million net of a credit for the annual license maintenance payment, for the achievement of

milestones under these agreements. In 2020, the Company owed payments to of $25.0 million for royalty expense related to the Sobi Agreement and
another licensing transaction.  This was paid in early January 2021.

In addition to the license agreement with Penn, the Company contracts to conduct research and development activities with third parties. Certain of
these contracts commit the Company to pay future milestone payments up to $15.0 million or to pay royalty fees ranging from 3-6% if any of the research
results in regulatory approval or commercial revenue for a product.

13. 401(k) Profit Sharing Plan and Trust

In July 2010, the Company adopted an employee profit-sharing plan (the “401(k) Plan”), qualified under Section 401(k) of the Internal Revenue
Code (the “IRC”). All of the Company’s full-time employees who have attained the age of 21 are eligible to participate in the 401(k) Plan immediately
upon employment. Pursuant to the 401(k) Plan, employees may elect to reduce their current compensation by up to the statutorily prescribed annual limit
and have the amount of the reduction contributed to the 401(k) Plan. In 2020, 2019 and 2018, the Company recorded $2.1 million, $0.8 million and $0.3
million respectively, for employer contributions made to the 401(k) Plan.

The Company’s effective rate for the year ended December 31, 2020 compared to the year ended December 31, 2019 increased primarily as a result

of subsidiary operations in foreign jurisdictions and state income taxes.

During the year ended December 31, 2020, in connection with a corporate reorganization, the Company transferred intellectual property between tax

jurisdictions, resulting in deferred tax benefit on basis difference on our intangible assets. The additional deferred tax asset was offset by valuation
allowance, resulting in no net impact on our effective tax rate

The Company accounts for income taxes in accordance with ASC Topic 740.  Deferred income tax assets and liabilities are determined based upon
temporary differences between the financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates and laws that will
be in effect when the differences are expected to reverse.

ASC Topic 740 requires a valuation allowance to reduce the deferred tax assets reported if, based on the weight of available evidence, it is more

likely than not that some portion or all of the deferred tax assets will not be realized.  After consideration of all the evidence, both positive and negative, the
Company has recorded full valuation allowances against its domestic and foreign deferred tax assets at December 31, 2020, because management has
determined that is it more likely than not that these assets will not be realized.  The valuation allowance increased by $240.2 million from December 31,
2019 to December 31, 2020, primarily due to increases in operating losses, development derivative liability, and the step-up in fair value of intellectual
property transfer.

At December 31, 2020, the Company had approximately $358.2 million and $405.0 million of Federal and state net operating loss carryforward,

respectively. At December 31, 2019, the Company had approximately $392.9 million and $358.3 million of Federal and state net operating loss
carryforwards, respectively. The Company also had federal and state research and development tax credit carryforwards $34.2 million and $6.5 million,
respectively of as of December 31, 2020. Federal net operating loss carryforward in the amount of $276.9 million may be carried forward indefinitely.  The
remaining federal and state net operating loss, research and development tax credit carryforwards begin to expire in 2025. The Company also has foreign
net operating loss carryforwards of $240.9 million which will begin to expire in 2026.

Under the provisions of the IRC, the net operating loss (“NOL”), and tax credit carryforwards are subject to review and possible adjustment by

the Internal Revenue Service and state tax authorities.  NOL and tax credit carryforwards may become subject to an annual limitation in the event of certain
cumulative changes in the ownership interest of significant stockholders over a three-year period in excess of 50%, as defined under Sections 382 and 383
of the IRC, respectively, as well as similar state provisions. This could limit the amount of tax attributes that can be utilized annually to offset future taxable
income or tax liabilities.  The amount of the annual limitation is determined based on the value of the Company immediately prior to the ownership
change.  Subsequent ownership changes may further affect the limitation in future years. The Company has completed several financings since its inception
that it believes may have resulted in a change in control as defined by Sections 382 and 383 of the IRC.

The Company does not have any unrecognized tax benefits during any periods presented and does not expect this to significantly change in the next

twelve months.  There were no interest and penalties recorded in the statement of operations during any period and no amounts accrued for interest and
penalties at December 31, 2020 or 2019.

The Company and its subsidiaries file income tax returns in the United States, as well as various state and foreign jurisdictions. Generally, the tax

years 2017 through 2019 remain open and subject to examination by the major taxing jurisdictions to which the

Company is subject. To the extent the Company has tax attribute carryforwards, the tax years in which the attribute was generated may still be adjusted
upon examination by the Internal Revenue Service, or state or foreign tax authorities, to the extent utilized in a future period.

15. Commitments and Contingencies

The Company has entered into a leasing agreement to amend the current office space leases in Waltham, Massachusetts (the “Amended Waltham

office space lease”).  The Amended Waltham office space lease adds additional office space in Waltham, Massachusetts with a commencement date of
January 1, 2021. The Amended Waltham office space lease amends all prior leasing arrangements for the Waltham office space, has a term of 72 months,
and includes leasing an additional 16,401 square feet of office space for a total of 77,818 leased square feet of office space. The Amended Waltham office
space lease provides for initial monthly lease payments of $0.3 million per month which is approximately a 20% increase to the existing per month rent
payment. The base rent payable over the lease period is $19.4 million.  

The Company contracts to conduct research and development activities with third parties. The scope of the services under the research and
development contracts can be modified and the contracts cancelled by the Company upon written notice. In some instances, the contracts may be cancelled
by the third party upon written notice. If the Company were to cancel these contracts as of December 31, 2019, the Company would be required to pay
certain termination costs and other fees of approximately $2.8 million that would be incurred in future periods.

The Company has certain non-cancelable purchase obligations related to the manufacturing of drug substance and drug product, primarily with

Bachem Americas, Inc, and Bachem AG, collectively (“Bachem”) for the drug substance for the finished dosage form of pegcetacoplan.  As of December
31, 2020, the Company has non-cancellable purchase commitments for 2021 with Bachem in the amount of approximately $13.7 million.

Following regulatory approval by the FDA or EMA of pegcetacoplan for the treatment of PNH, the Company has certain payment and other

obligations under the SFJ agreement, which are discussed above in Note 5.

Indemnifications—In the ordinary course of business, the Company enters into agreements that may include indemnification provisions. Pursuant to

such agreements, the Company may indemnify, hold harmless and defend indemnified parties for losses suffered or incurred by the indemnified party.
Some of the provisions will limit losses to those arising from third-party actions. In some cases, the indemnification will continue after the termination of
the agreement. The maximum potential amount of future payments the Company could be required to make under these provisions is not determinable. The
Company has not incurred any cost to defend lawsuits or settle claims related to these indemnification provisions.

Legal—During the normal course of business, the Company may be a party to legal claims that may not be covered by insurance. Management does

not believe that any such claims would have a material impact on the Company’s consolidated financial statements.

16. Equity Incentive Plans

Share-based Compensation

The Company’s Board of Directors adopted, and its stockholders approved, an equity incentive plan in 2010 (as amended, the “2010 Plan”). The

Board of Directors and stockholders amended the 2010 Plan in August 2017 to increase the number of shares of common stock reserved for issuance
thereunder to 6,188,466. The 2010 Plan allowed for the grant of incentive stock options and non-qualified stock options to purchase common stock for
employees, directors and consultants under terms and conditions established by the Board of Directors. Incentive stock options and nonqualified stock
options were granted at exercise prices that were no less than 100% of the estimated fair value per share of the common stock on the date of grant. If an
individual owns capital stock representing more than 10% of the voting shares, the price of each share was at least 110% of the fair value on the date of
grant. The Board of Directors determined the fair value of common stock with the assistance of a third-party specialist. Options expire 10 years from the
issuance date. Following the adoption of the 2017 Stock Incentive Plan, the Company no longer grants stock options or other awards under the 2010 Plan.

In October 2017, the Company’s Board of Directors adopted, and its stockholders approved, the 2017 Stock Incentive Plan (the “2017 Plan”), which

became effective on November 8, 2017. The 2017 Plan provides for the grant of incentive stock options, non-statutory stock options, stock appreciation
rights, awards of restricted stock, restricted stock units and other stock-based awards. The number of shares of common stock reserved for issuance under
the 2017 plan is the sum of (i) 1,359,587 shares of common stock, plus (ii) an additional number of shares of common stock equal to the sum of (a) the
number of shares of common stock reserved for

130

 
issuance under the 2010 equity incentive plan that remained available for future issuance immediately prior to the effectiveness of the 2017 Plan, which
was 299,568 shares, and (b) the number of shares of common stock subject to outstanding awards under the 2010 equity incentive plan upon effectiveness
of the 2017 plan that expire, terminate or are otherwise surrendered, cancelled, forfeited or repurchased by us at their original issuance price pursuant to a
contractual repurchase right plus (iii) an annual increase, to be added the first day of each fiscal year, beginning with the fiscal year ending December 31,
2018 and continuing until, and including, the fiscal year ending December 31, 2027, equal to the lowest of 4,219,409 shares of common stock, 4.0% of the
number of shares of common stock outstanding on the first day of the fiscal year and an amount determined by the board of directors.  

As of December 31, 2020, a total of 8,613,049 shares of common stock were reserved for issuance under the 2017 Plan. In January 2021, the shares

available for future issuance under the 2017 plan were increased by 3,045,189 shares pursuant to the annual increase described above.

Additionally, during 2019 and thereafter, the Company has granted equity awards as equity inducement awards material to entry into employment

with the Company to certain newly hired employees outside of the Company’s existing plans in accordance with Nasdaq listing rule 5635(c)(4).  In
February 2020 the Board of Directors adopted the 2020 Inducement Stock Incentive Plan (the “2020 Plan”), which permitted the Company to grant equity
awards to newly hired employees in accordance with Nasdaq listing rule 5635(c)(4).   The aggregate number of shares reserved for issuance under the 2020
Plan was initially 750,000 shares but was increased to 1,050,000 shares in January 2021.

In October 2017, the Company’s board of directors adopted and the Company’s stockholders approved the 2017 Employee Stock Purchase Plan

(“ESPP”), which became effective upon the IPO and provides participating employees with the opportunity to purchase up to an aggregate of
468,823 shares of common stock. The number of shares of common stock reserved for issuance under the 2017 ESPP will automatically increase on the
first day of each fiscal year, beginning with the fiscal year ending December 31, 2018 and continuing until, and including, the fiscal year ending December
31, 2027, equal to the lowest of (i) 937,646 shares of common stock, (ii) 1.0% of the number of shares of common stock outstanding on the first day of the
fiscal year and (iii) an amount determined by the board of directors. The board of directors initiated the first offering under ESPP in October 2019.

Stock Options—Options granted generally vest over 48 months. Options granted to employees on or after December 5, 2013 generally vest in
installments of (i) 25% at the one-year anniversary and (ii) in either 36 equal monthly or 12 equal quarterly installments beginning in the thirteenth month
after the initial vesting commencement date (as defined) subject to the employee’s continuous service with the Company. Options granted before
December 5, 2013 vest over four years in equal annual installments of 25% at each anniversary of the grant date.

Under the Executive Separation Benefits and Retention Plan and by resolutions adopted by the Compensation Committee in October 2019, the stock

options granted to the Company’s executives and employees will become fully vested upon the occurrence of a change in control, as defined in the
Executive Separation Benefits and Retention Plan, if such executive or employee is terminated without cause or resigns for good reason within 12 months
after such change in control.

The aggregate intrinsic values of options outstanding, exercisable, vested and expected to vest were calculated as the difference between the exercise

price of the options and the fair value of the common stock as of December 31, 2020.

During the years ended December 31, 2020, 2019 and 2018, the Company granted stock options to purchase an aggregate of 2.9 million, 4.4 million

and 2.1 million shares of its common stock, respectively with weighted average grant date fair values of $27.52, $17.31 and $13.13, respectively.

The aggregate intrinsic value of options exercised during the years ended December 31, 2020, 2019 and 2018 were $38.0 million, $15.7 million, and
$5.0 million respectively calculated as the difference between the exercise price of the underlying options and the estimated fair value of the common stock
for the options on the respective date of exercise.

The fair market value of options vested during the years ended December 2020, 2019 and 2018 was $33.6 million, $12.9 million and $5.1 million,

respectively.

At December 31, 2020, unrecognized compensation expense related to unvested options, was $100.1 million, which the Company expects to

recognize over an estimated weighted-average period of 2.84 years.  

The assumptions used in the Black-Scholes model to estimate the grant date fair value are as follows:

Eligible employees who elect to participate in an offering under the ESPP may have up to 15 percent of their earnings withheld, subject to certain
limitations, to purchase shares of common stock pursuant to the ESPP. The price of common stock purchased under the ESPP is equal to 85 percent of the
lower of the fair market value of the common stock at the commencement date of each offering period or the relevant purchase date. During the year ended
December 31, 2020, a total of 58,938 shares of common stock were issued under the ESPP at average per share price of $26.71. During the year ended
December 31, 2020, the Company recorded cash received from the issuance of stock to the ESPP of $1.6 million and recorded $0.8 million of stock-based
compensation expense related to the ESPP.

Effective as of May 1, 2018, the Company entered into a subscription license agreement and a services agreement with Revon Systems, Inc.

(“Revon”). Under the subscription license agreement, Revon granted the Company an exclusive license to use the Revon software platform and
applications for any purpose with respect to the Company's programs in age-related macular degeneration, hemolytic diseases and complement-
dependent nephropathies for an annual license fee of $0.2 million and an option to obtain a perpetual, exclusive license thereafter for $0.4 million. Under
the services agreement, Revon provided development services with respect to the Revon software to the Company for $0.3 million during the first year.
Prior to the acquisition of Revon by an unrelated third party in July 2019, the Company paid the remainder of the annual license fee due for the second
year, exercised the option for the perpetual license and discontinued the services agreement. For the year ended December 31, 2019, the Company paid
Revon a total of $0.7 million. There were no payments under the agreement during the year ended December 31, 2020.

Each of Cedric Francois, the Company’s chief executive officer, Pascal Deschatelets, the Company’s chief operating officer, and Alec Machiels, a

member of the board of directors, was an affiliate of Revon. The Board approved the Revon agreements after review by a subcommittee of the disinterested
members of the Board and determination by the full Board that the terms of the Revon agreements were fair, reasonable and in the best interests of the
Company. The exercise of the option for the perpetual license was approved in accordance with the Company’s related party transaction policy.

(1) The sum of the four quarters of earnings per share for 2020 and 2019 may not add to the full year earnings per share amount due to rounding

and/or the use of quarter-to-date weighted average shares to calculate the earnings per share amount in each respective quarter.  For the quarter
ended December 31, 2020, diluted net income per common share was calculated using the if-converted method, which adjusts both the numerator
by removing the interest expense associated with the Convertible Notes and the denominator by increasing the share count.  

20. Subsequent Events

On January 6, 2021, the Company entered into separate, privately negotiated exchange agreements with certain holders of its 2019 Convertible

Notes. Under the terms of these exchange agreements, the holders exchanged approximately $126.1 million in aggregate principal amount of 2019
Convertible Notes held by them for an aggregate of 3,906,869 shares of common stock issued by the Company. The exchange transactions closed in
January 2021.

Item 9A. Controls and Procedures.

Evaluation of Disclosure Controls and Procedures

The Company’s management, with the participation of the Company’s chief executive officer and chief financial officer, evaluated the

effectiveness of the Company’s disclosure controls and procedures as of as of December 31, 2020. The term “disclosure controls and procedures,” as
defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, or the Exchange Act, means controls and other procedures of a
company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is
recorded, processed, summarized and reported, within the time periods specified in the SEC's rules and forms. Disclosure controls and procedures include,
without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits
under the Exchange Act is accumulated and communicated to the company’s management, including its principal executive and principal financial officers,
as appropriate to allow timely decisions regarding required disclosure. Management recognizes that any controls and procedures, no matter how well
designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating
the cost-benefit relationship of possible controls and procedures. Based on the evaluation of the Company’s disclosure controls and procedures as of
December 31, 2020, the Company’s chief executive officer and chief financial officer concluded that, as of such date, the Company’s disclosure controls
and procedures were effective at the reasonable assurance level.

Management’s Report on Internal Control Over Financial Reporting

The management of the Company is responsible for establishing and maintaining adequate internal control over financial reporting as defined in
Rule 13a-15(f) or 15d-15(f) under the Exchange Act. Our internal control over financial reporting is a process designed by, or under the supervision of, the
company’s principal executive and principal financial officers and effected by the company’s board of directors, management and other personnel, to
provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance
with generally accepted accounting principles and includes those policies and procedures that:

•

•

•

Pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of the
assets of the Company;

Provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance
with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance
with authorizations of management and directors of the Company; and

Provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the
Company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements.  Projections of any
evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree
of compliance with the policies or procedures may deteriorate.

The company’s management assessed the effectiveness of the company’s internal control over financial reporting as of December 31, 2020. In

making this assessment, the Company’s management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway
Commission in Internal Control-Integrated Framework (2013).

Based on our assessment, management concluded that, as of December 31, 2020, the Company’s internal control over financial reporting is

effective based on those criteria.

Deloitte & Touche LLP, the Company’s independent auditors have issued an audit report on our assessment of the company’s internal control

over financial reporting, which is included below.

Changes in Internal Control over Financial Reporting

As required by Rule 13a‑15(d) of the Exchange Act, our management, including our principal executive officer and our principal financial

officer, conducted an evaluation of the internal control over financial reporting to determine whether any changes occurred during the year ended
December 31, 2020 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. Based on that
evaluation, our principal executive officer and principal financial officer concluded no such changes during the year ended December 31, 2020 materially
affected, or were reasonably likely to materially affect, our internal control over financial reporting.

As a result of the COVID-19 pandemic, beginning in March 2020, certain of our employees began working remotely.  We have not identified any

material changes in the Company’s internal control over financial reporting as a result of these changes to the working environment.  We are continually
monitoring and assessing the COVID-19 situation to determine any potential impacts on the design and operating effectiveness of our internal controls over
financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders and the Board of Directors of Apellis Pharmaceuticals, Inc.

Opinion on Internal Control over Financial Reporting

We have audited the internal control over financial reporting of Apellis Pharmaceuticals, Inc. and subsidiaries (the “Company”) as of December 31, 2020,
based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway
Commission (COSO). In our opinion, the Company maintained, in all material respects,

135

 
 
 
 
 
effective internal control over financial reporting as of December 31, 2020, based on criteria established in Internal Control — Integrated Framework
(2013) issued by COSO.
We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated
financial statements as of and for the year ended December 31, 2020, of the Company and our report dated February 25, 2021, expressed an unqualified
opinion on those financial statements.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of
internal control over financial reporting, included in the accompanying Management’s Report on Internal Control Over Financial Reporting. Our
responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm
registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the
applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an
understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating
effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We
believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting
and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control
over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly
reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit
preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are
being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding
prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial
statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of
effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of
compliance with the policies or procedures may deteriorate.

entitled to vote on the election. Any matter other than the election of directors to be voted upon by the stockholders at such meeting will be decided by the
affirmative vote of our stockholders having a majority in voting power of the votes cast by the stockholders present or represented and voting on such
matter, except when a different vote is required by law, our certificate of incorporation or our bylaws.

Dividends. Holders of Common Stock are entitled to receive proportionately any dividends as may be declared and paid on the Common Stock from
funds lawfully available therefor as and when determined by our board of directors, subject to any preferential dividend rights of any outstanding preferred
stock.

Liquidation and Dissolution. In the event of our liquidation or dissolution, whether voluntary or involuntary, the holders of Common Stock are

entitled to receive proportionately all assets available for distribution to stockholders after the payment of all debts and other liabilities and subject to the
prior rights of any outstanding preferred stock.

Other Rights. Holders of Common Stock have no preemptive, subscription, redemption or conversion rights. The rights, preferences and privileges

of holders of Common Stock are subject to and may be adversely affected by the rights of the holders of shares of any series of preferred stock that we may
designate and issue in the future. Outstanding shares of our Common Stock are non-assessable. Holders of our Common Stock are not, and will not be,
subject to any liability as stockholders.

Anti-Takeover Effects of Delaware Law and Our Certificate of Incorporation and Bylaws

Delaware law contains, our restated certificate of incorporation and our amended and restated bylaws contain, provisions that could have the effect

of delaying, deferring or discouraging another party from acquiring control of us. These provisions, which are summarized below, are expected to
discourage coercive takeover practices and inadequate takeover bids. These provisions are also designed to encourage persons seeking to acquire control of
us to first negotiate with our board of directors.

Staggered Board; Removal of Directors. Our restated certificate of incorporation and amended and restated bylaws divide our board of directors into

three classes with staggered three-year terms. In addition, a director may be removed only for cause and only by the affirmative vote of the holders of at
least 75% of the votes that all of our stockholders would be entitled to cast in an annual election of directors. Any vacancy on our board of directors,
including a vacancy resulting from an enlargement of our board of directors, may be filled only by vote of a majority of our directors then in office. The
classification of our board of directors and the limitations on the removal of directors and filling of vacancies could make it more difficult for a third party
to acquire, or discourage a third party from seeking to acquire, control of us.

Stockholder Action by Written Consent; Special Meetings. Our restated certificate of incorporation provides that any action required or permitted to
be taken by our stockholders must be effected at a duly called annual or special meeting of such holders and may not be effected by any consent in writing
by such holders. Our restated certificate of incorporation and amended and restated bylaws also provide that, except as otherwise required by law, special
meetings of our stockholders can only be called by our chairman of the board, our chief executive officer or our board of directors.

Advance Notice Requirements for Stockholder Proposals. Our amended and restated bylaws establish an advance notice procedure for stockholder

proposals to be brought before an annual meeting of stockholders, including proposed nominations of persons for election to our board of directors.
Stockholders at an annual meeting may consider proposals or nominations specified in the notice of meeting or brought before the meeting by or at the
direction of our board of directors or by a stockholder of record on the

ActiveUS 178437549v.2

 
 
 
record date for the meeting who is entitled to vote at the meeting and who has delivered timely written notice in proper form to our secretary of the
stockholder’s intention to bring such business before the meeting. These provisions could have the effect of delaying until the next stockholder meeting
stockholder actions that are favored by the holders of a majority of our outstanding voting securities.

Issuance of Preferred Stock. Our board of directors is authorized, without further action by our stockholders, to issue up to 10,000,000 shares of
preferred stock in one or more series, and to fix the designations, powers, preferences and the relative, participating, optional or other special rights, and
any qualifications, limitations and restrictions of the shares of each series of preferred stock. The issuance of preferred stock could impede the completion
of a merger, tender offer or other takeover attempt.

Delaware Business Combination Statute. We are subject to Section 203 of the General Corporation Law of the State of Delaware. Subject to certain
exceptions, Section 203 prevents us from engaging in a “business combination” with any “interested stockholder” for three years following the date that the
person became an interested stockholder, unless the interested stockholder attained such status with the approval of our board of directors or unless the
business combination is approved in a prescribed manner. A “business combination” includes, among other things, a merger or consolidation involving us
and the “interested stockholder” and the sale of more than 10% of our assets. In general, an “interested stockholder” is any entity or person beneficially
owning 15% or more of our outstanding voting stock and any entity or person affiliated with or controlling or controlled by such entity or person.

Amendment of Certificate of Incorporation and Bylaws. The General Corporation Law of the State of Delaware provides generally that the
affirmative vote of a majority of the shares entitled to vote on any matter is required to amend a corporation’s certificate of incorporation or bylaws, unless
a corporation’s certificate of incorporation or bylaws, as the case may be, requires a greater percentage. Our amended and restated bylaws may be amended
or repealed by a majority vote of our board of directors or by the affirmative vote of the holders of at least 75% of the votes that all of our stockholders
would be entitled to cast in any annual election of directors. In addition, the affirmative vote of the holders of at least 75% of the votes that all of our
stockholders would be entitled to cast in any annual election of directors is required to amend or repeal or to adopt any provisions inconsistent with any of
the provisions of our restated certificate of incorporation described above under “—Staggered Board; Removal of Directors” and “—Stockholder Action by
Written Consent; Special Meetings.”

Exclusive Forum Selection. Our restated certificate of incorporation provides that, unless we consent in writing to the selection of an alternative

forum, the Court of Chancery of the State of Delaware shall be the sole and exclusive forum for (1) any derivative action or proceeding brought on behalf
of the Company, (2) any action asserting a claim of breach of a fiduciary duty owed by any of our directors, officers, employees or stockholders to the
Company or our stockholders, (3) any action asserting a claim against the Company arising pursuant to any provision of the General Corporation Law of
the State of Delaware or our restated certificate of incorporation or amended and restated bylaws, or (4) any action asserting a claim against the Company
governed by the internal affairs doctrine. Although our restated certificate of incorporation contains the choice of forum provision described above, it is
possible that a court could rule that such a provision is inapplicable for a particular claim or action or that such provision is unenforceable.

6.

Condition of Third Expansion Premises. Subject to the terms of this Section 5, the Third Expansion
Premises are being leased by Tenant in their condition as of the Third Expansion Premises Term
Commencement Date, in their “As Is” condition as of the Effective Date, without representation or warranty
by Landlord, except that the Third Expansion Premises shall be delivered to Tenant vacant (and all existing
leases or occupancy agreements terminated), broom clean, with all furniture, fixtures and equipment removed,
other than the furniture located on the Lower Level Expansion Premises, and in compliance with all
applicable laws.  Tenant acknowledges and agrees that Tenant inspected the Third Expansion Premises prior
to the execution of this Amendment and is satisfied with the condition of the Third Expansion
Premises.  With respect to the furniture located on the Lower Level Expansion Premises, Landlord hereby
conveys its interest in the same, if any, to Tenant without warranty, representation or recourse of any
kind.  There is no warranty relating to title, possession, quiet enjoyment, or the like in this disposition.

Landlord’s Third Expansion Contribution.  Landlord shall provide to Tenant a contribution in the amount
of $410,025 (the “Landlord’s Third Expansion Contribution”) to be used towards Tenant’s improvements
to the Third Expansion Premises (including both hard and soft costs of construction, as well as the purchase
and installation of Tenant’s cabling, wiring, furniture, fixtures and equipment), subject to the provisions stated
in this Section 6 of this Amendment.    

(a) Tenant shall prepare, at its sole cost and expense (against which the Landlord’s Third Expansion

Contribution may be applied), plans (the “Third Expansion Plans”) for the interior finish and layout of
the initial improvements (the “Third Expansion Initial Work”) which Tenant desires to have
performed in the Third Expansion Premises.  The Third Expansion Plan shall be submitted to Landlord,
together with a construction budget setting forth the anticipated costs for the Third Expansion Initial
Work (the “Third Expansion Estimated Initial Work Budget”), and Landlord shall approve or
disapprove of the Third Expansion Plans, in its reasonable discretion, within ten (10) Business Days of
receiving them.  No work shall be conducted by or on behalf of Tenant until the Third Expansion Plans
have been fully approved in writing by Landlord.  At Tenant’s sole cost and expense (against which the
Landlord’s Third Expansion Contribution may be applied), Tenant shall cause the Third Expansion Plans
to be revised in a manner sufficient to remedy the Landlord’s objections and/or respond to the
Landlord’s concerns and for such revised Third Expansion Plans to be redelivered to Landlord, and
Landlord shall approve or disapprove Tenant’s revised Third Expansion Plans within five (5) Business
Days following the date of resubmission, unless such revised Third Expansion Plans involve structural
alterations to the Building or the HVAC, in which case Landlord shall approve or disapprove such
revised Third Expansion Plans within ten (10) Business Days.  Landlord’s failure to timely respond to
Tenant’s

1031382.v4

4

 
 
 
 
 
 
 
submitted Third Expansion Plans or revised Third Expansion Plans shall be deemed to be an approval
thereof.  

(b) The Third Expansion Plans shall be stamped by a Massachusetts registered architect and engineer, such
architect and engineer and Tenant’s  general contractor, being subject to Landlord’s prior reasonable
approval, and shall comply with Applicable Law and the requirements of the Rules and Regulations and
shall be in a form satisfactory to appropriate governmental authorities responsible for issuing permits,
approvals and licenses required for such Third Expansion Initial Work.  

(c) All of the Third Expansion Initial Work shall be completed in accordance with the requirements set forth

in the Rules and Regulations for Tenant Alterations.

(d) Landlord shall reimburse Tenant for the costs incurred by the Tenant with respect to the design and

performance of the Third Expansion Initial Work (the “Cost of Third Expansion Initial Work”) up to
the amount of Landlord’s Third Expansion Contribution, subject to the provisions hereof.  To the extent
that the Cost of Third Expansion Initial Work exceeds the Landlord’s Third Expansion Contribution,
Tenant shall be entirely responsible for such excess.  Landlord’s Third Expansion Contribution shall be
payable by Landlord to Tenant (or, at Landlord’s election, directly to Tenant’s general contractor or
subcontractors) in installments according to Landlord’s construction disbursement procedures set forth
below, as the Third Expansion Initial Work progresses.  Prior to payment of any such installment, Tenant
shall deliver to Landlord a written request, to be submitted no more frequently than once every thirty
(30) days, for such disbursement, which request shall be accompanied by: (i) invoices for the Third
Expansion Initial Work covered by such requisition; (ii) copies of partial lien waivers or final lien
waivers (in the case of a final installment) from (I) all contractors and subcontractors holding contracts
in excess of $10,000 whose work is covered by such requisition or (II) in the event that the aggregate
amount of Tenant’s contracts in connection with the Third Expansion Initial Work exceeds $25,000,
from any contractors and subcontractors whose work is covered by such requisition; and (iii) a
certificate signed by the Architect certifying that the Third Expansion Initial Work represented by the
aforementioned invoices has been completed substantially in accordance with the Third Expansion
Plans.  Landlord shall make each such payment, as set forth above, within forty-five (45) days of
Landlord’s receipt of the documentation described above. If at any time the amount of Landlord’s Third
Expansion Contribution remaining is insufficient to pay for the remaining amount of the Third
Expansion Initial Work, then Tenant shall pay from its own funds all amounts required to accomplish
lien free completion of the Third Expansion Initial Work. In the event that Landlord fails to pay all or
any portion of Landlord’s Third Expansion Contribution to Tenant when due, and such failure continues
for thirty (30) days after written notice is delivered to Landlord from Tenant, Tenant may

offset the amount of the unpaid Landlord’s Third Expansion Contribution against rent due until all of
such unpaid Landlord’s Third Expansion Contribution has been recouped by Tenant.

Offset to Basic Rent. Tenant may, at Tenant’s option, use up to one hundred percent (100%) of the
Landlord’s Third Expansion Contribution to offset Base Rent next coming due, with the balance carried
forward and applied towards each of the next rental payments until Landlord’s Third Expansion Contribution
has been fully used.

Landlord’s Current Space Contribution.  In addition to the Landlord’s Third Expansion Contribution,
Landlord shall provide to Tenant a contribution in the amount of $245,688 (the “Landlord’s Current
Premises Contribution”) to be used towards Tenant’s improvements to the Current Premises, subject to the
condition that the provisions described in Section 6 of this Amendment shall also apply to Landlord’s Current
Space Contribution and any references to Landlord’s Third Expansion Premises Contribution, Third
Expansion Plans, Third Expansion Initial Work, Third Expansion Estimated Initial Work Budget and Cost of
Third Expansion Initial Work shall be deemed to refer instead to “Landlord’s Current Premises Contribution”
and the plans and specifications, work and budget therefor.

Initial Access.  Upon the Third Expansion Premises Term Commencement Date, Tenant shall have full use
and access of the Third Expansion Premises and all of Tenant’s obligations hereunder shall commence,
provided that Tenant shall deliver to Landlord certificates of insurance evidencing the coverages required by
the Lease.  Notwithstanding the foregoing, Tenant’s obligations to pay Basic Rent, Additional Rent and
electric fees in relation to the Third Expansion Premises shall not commence until the Third Expansion
Premises Rent Commencement Date.

Yield-Up and Surrender of Premises.  Tenant shall yield-up and surrender the Current Premises and the
Third Expansion Premises on or prior to the Expiration Date in strict accordance with Article 16 of the Lease.
Failure to yield-up and surrender the Current Premises and Third Expansion Premises in accordance with this
Section 10 shall constitute a Default of Tenant under the Lease and entitle Landlord to exercise any and all of
the remedies to which Landlord is entitled under the Lease, at law or in equity.

Brokers. Each of Landlord and Tenant hereby represents that such party has not dealt with any brokers with
respect to the transactions contemplated by this other than Jeremy Hood and CBRE (together, the
“Broker”).  Each of Landlord and Tenant hereby agrees to defend, indemnify and hold harmless the other,
and its successors and assigns, against and from all claims, losses, liabilities and expenses including, without
limitation, reasonable attorney’s fees, arising out of any claim by any broker, consultant, finder or like agent,
which are based upon

alleged dealings by such party with respect to this Amendment other than the Broker. Provided that this
Amendment is executed by the Landlord and the Tenant, the Landlord shall pay to the Broker a commission
fee per a separate agreement.

NRT Termination Agreement.  Landlord and Tenant acknowledge and agree that all the rights and
obligations of each party pursuant to this Amendment are contingent upon the following (i) the full execution
of that certain Termination of Lease Agreement by and between NRT New England LLC, a Delaware limited
liability company (“NRT”), and Landlord, to be signed and dated simultaneously herewith (the “NRT
Termination Agreement”); (ii) the satisfaction by NRT of all of the terms and conditions of the NRT
Termination Agreement no later than five (5) business days following the execution date of said agreement,
including, without limitation, the payment by NRT of any amounts due pursuant to the NRT Termination
Agreement.  Following Landlord’s confirmation that the conditions of items (i) and (ii) above are satisfied,
Landlord shall certify of the same to Tenant (the “NRT Termination Satisfaction Notice”), and this Section
12 shall be of no further force and effect.  For the avoidance of doubt, in the event that the NRT Termination
Agreement is not fully executed and dated by Landlord and NRT as of the date of this Amendment and/or the
terms and conditions of the NRT Termination Agreement are not fully satisfied within five (5) business days
following its execution date, Landlord shall promptly (and in any event within seven (7) Business Days
following  the Effective of this Amendment) deliver written notice thereof to Tenant and this Amendment
shall be null and void.

Capitalized Terms.  Capitalized terms that are not otherwise defined herein shall have the meaning set forth
in the Lease.

Ratification of Existing Lease Terms.  Other than as expressly set forth herein, the terms and provisions of
the Lease are hereby ratified, confirmed and shall remain unmodified and in full force and effect.

Governing Law.  This Amendment shall be governed by the laws of the Commonwealth of Massachusetts
without regard to its conflict of law provisions.

Counterpart Signatures.  This Amendment may be executed in counterparts, each of which shall constitute
an original document and all of which, together, shall constitute one and the same instrument, and computer-
scanned image signatures hereon shall be binding. Facsimile, electronic or scanned signatures shall be
deemed originals for all purposes.

(d)

sales  and  use  taxes,  tariffs,  customs  duties,  excises,  and  other  taxes  and  fees  imposed  by  a  Governmental

negotiated payments made to private sector and government Third Party payors (e.g., PBMs, HMOs, PPOs)
and  purchasers  or  providers  (e.g.,  staff  model  HMOs,  hospitals,  clinics),  regardless  of  the  payment
mechanism, including rebate, chargeback, and credit mechanisms;

discounts under discount prescription drug programs and reductions for coupon and voucher programs; and

bad  debts  calculated  in  accordance  with  Accounting  Standards,  except  that  any  reductions  to  bad  debts
previously  deducted  from  Gross  Sales  will  become  an  add  back  to  Net  Sales  in  the  Calendar  Quarter  in
which the reduction in bad debt is recognized.

Such  amounts  will  be  determined  consistent  with  the  applicable  Selling  Party’s  customary  practices  and  Accounting

Standards. All deductions will be applied on a non-duplicative basis.

Notwithstanding anything to the contrary in the foregoing, “Net Sales” will only include sales of Products to a Third
Party for any expanded access program or compassionate sales or use program (including any named patient program or single
patient program) to the extent such sales are above cost.

For the purposes of calculating and reporting the Net Sales in any country in which the Product is Commercialized via a
Functional Sublicensee under Section 1.149(y) (Net Sales), Sobi will use Commercially Reasonable Efforts to provide reasonable
estimates  of  such  Net  Sales  for  such  country  at  the  end  of  each  Calendar  Quarter,  provided that,  at  the  end  of  the  fourth  (4th)
Calendar Quarter in each year in the Term, Sobi shall use Commercially Reasonable Efforts to procure the actual amounts of such
Net Sales in such country in such Calendar Year and, if such actual amounts are obtained by Sobi, Sobi shall perform a true-up of
such quarterly estimates of Net Sales for such country, following which the Parties shall coordinate in good faith to implement any
required adjustment to the Net Sales for such country for such period for the purposes of this Agreement.

Notwithstanding anything to the contrary in the foregoing, “Net Sales” will not include any sales at or below cost for

test marketing, pre-clinical or clinical studies, or disposition of samples in customary quantities.

If  non-monetary  consideration  is  received  by  a  Selling  Party  for  any  Product,  Net  Sales  for  such  transaction  will  be
calculated  based  on  the  fair  market  value  of  such  non-monetary  consideration  (calculated  as  the  cash  consideration  that  the
applicable Selling Party would realize

18

 
 
 
 
 
 
 
 
 
 
from an unrelated buyer in arm’s length sale of an identical item sold in the same quantity and at the same time and place of the
transaction), as determined by the Parties in good faith.  If the Parties are unable to agree on the fair market value, then the dispute
will be resolved in accordance with Article 16 (Dispute Resolution).

Except as expressly set forth in Section 1.149(y)(ii)(A) (Net Sales), Sales or transfers of Products between any of the
Selling Parties will not result in any Net Sales, with Net Sales to be based only on any subsequent sales or dispositions to a non-
Selling Party.

In the case of a Combination Product containing a given Compound, Net Sales for purposes of determining payments
hereunder attributable to the Product from the sale, use, lease, transfer, or other disposition of such Combination Product shall be
determined  by  multiplying  Net  Sales  of  the  Combination  Product  by  the  fraction  A/(A+B),  where  A  is  the  weighted  (by  sales
volume)  average  sales  price  of  a  Product  containing,  as  its  sole  active  ingredient,  such  Compound  when  sold  separately  in
Finished Form (the “Non-Combination Product”) and B is the weighted average sale price of the other active ingredient(s) sold
separately in finished form, in each case during the applicable royalty reporting period or, if sales of both the Non-Combination
Product and the other active ingredient(s) did not occur in such period, then in the most recent royalty reporting period in which
sales  of  both  occurred;  provided that  the  value  attributed  to  the  Non-Combination  Product  as  a  component  of  the  Combination
Product resulting from such calculation shall never be less than the weighted (by sales volume) average sales price of the Non-
Combination Product when sold separately in Finished Form.  In the event that such average sales price cannot be determined for
both  the  Non-Combination  Product  and  the  other  active  ingredient(s)  in  combination,  Net  Sales  for  purposes  of  determining
payments hereunder shall be mutually agreed by the Parties based on the relative value contributed by each component, and such
agreement shall not be unreasonably withheld, provided if the Parties are unable to agree, the same shall be subject to the baseball
arbitration procedure set forth in Section 16.5.1 (Baseball Arbitration).

New In-Licenses.     If  a  Party  becomes  aware  of  any  Third  Party  Intellectual  Property  that  such  Party  believes  is  necessary  or
useful  for  the  Exploitation  of  any  Products  developed  pursuant  to  the  Global  Development  Plan  (“Additional  Third  Party  IP”),
such Party shall notify the JEC, and the JEC shall discuss in good faith whether, and on what terms, either Party should obtain a
sublicensable  license  to  such  Third  Party  Intellectual  Property,  but  nothing  in  this  Section  2.3  (New  In-Licenses)  shall  prevent
either  Party  from  independently  obtaining  or  negotiating  the  terms  for  a  license  to  such  Additional  Third  Party  IP.  The  Party
obtaining a license or other rights to any Additional Third Party IP shall use Commercially Reasonable Efforts to ensure that any
and all such rights acquired are freely sublicenseable to the other Party to the extent of the licenses and rights granted to such other
Party under this Agreement. No more than [**] after executing an agreement pursuant to which it has obtained a license or other
rights to any Additional Third Party IP that are sublicensable to the other Party under this Agreement, the in-licensing Party shall
provide to the other Party a copy of such agreement and a proposed apportionment of the costs of such license between the Parties,
based  upon  the  Parties’  proportional  interest  in  the  rights  under  such  agreement,  and  such  other  Party  shall,  within  [**]  of
receiving such copy, notify the in-licensing Party in writing whether such other Party agrees (a) to be responsible for the costs of
such  agreement  in  accordance  with  the  terms  of  Section  9.6.2  (Collaboration  In-Licenses)  and  (b)  accept  all  other  obligations
under such agreement that are applicable to such Party’s Exploitation of Products under this Agreement. If such other Party agrees
to  be  responsible  for  such  costs,  and  accept  such  other  obligations  that  are  applicable  to  such  Party’s  Exploitation  of  Products
under  this  Agreement,  under  such  agreement,  then  such  agreement  shall  be  deemed  a  “Collaboration  In-License,”  and  the
Additional Third Party IP licensed under such Collaboration In-License shall be Apellis Know-How, Apellis Patent Rights, Sobi
Know-How, or Sobi Patent Rights, as applicable.  If such other Party does not agree to be responsible for such costs, and accept
such other obligations that are applicable to such Party’s Exploitation of Products under this Agreement, under such agreement, or
if the rights licensed under such agreement are not sublicensable to the other Party under this Agreement, then such agreement
shall not be a Collaboration In-License, and the Additional Third Party IP licensed under such agreement shall be deemed not to
be Apellis Know-How, Apellis Patent Rights, Sobi Know-How, or Sobi Patent Rights.

designations (or equivalent) that Apellis assigns to Sobi, Apellis shall, at Sobi’s reasonable request therefor,promptly
execute  and  deliver,  or  cause  to  be  executed  and  delivered,  to  Sobi  or  any  applicable  Regulatory  Authority  such

Affiliates;  except  that  each  Party  will  remain  responsible  for  and  be  the  guarantor  of  any  such  performance  by  its
Affiliates and will cause its Affiliates to comply with the terms and conditions of this Agreement in connection with
such performance.  Each Party hereby expressly waives any requirement that the other Party exhaust any right, power,
or  remedy,  or  proceed  against  any  of  such  Party’s  Affiliates,  for  any  obligation  or  performance  hereunder  prior  to
proceeding directly against such Party.

Sublicenses.  Subject to the terms and conditions of section 1.5 of the Penn Other Fields License Agreement regarding
sublicensing  through  multiple  tiers  (which  provides  that,  if  Sobi  desires  to  sublicense  any  Commercialization  rights
under any rights licensed under the Penn Other Fields License Agreement to a further sublicensee that is not an Affiliate
of Sobi, Sobi and Apellis shall notify Penn of the identity of such non-Affiliate further sublicensee within [**] after the
grant of such further sublicense, and any such downstream sublicense must require the sub-sublicensee to comply with

(f)

Subject to Section 2.5.1 (Performance by Affiliates), each Party will have the right to sublicense (including

Party’s Affiliates without the consent of the other Party.

Subject to Sections 2.5.2(c) (Sublicenses), 2.5.2(e) (Sublicenses), and 2.5.2(f) (Sublicenses), each Party will
have the right to sublicense any or all of the rights granted to it by the other Party under this Agreement in
connection with delegating any of such Party’s obligations to Subcontractors in connection with exercising
such Party’s rights or performing such Party’s obligations under this Agreement, except that (i) other than
with respect to any contract research organization engaged by Apellis as of the Effective Date, neither Party
may  engage  any  contract  research  organization  to  perform  any  Global  Development  Activities  until  such
Party  has  consulted  with  the  other  Party  with  respect  to  the  engagement  of  such  contract  research
organization and (ii) no Subcontractor may grant any further sublicense. For clarity, clause (i) shall not apply
to a Party using a contract research organization in respect of such Party’s Regional Development Activities.

Subject  to  Section  2.5.2(f)  (Sublicenses),  Sobi  will  have  the  right  to  sublicense  any  or  all  of  the  rights
granted  to  it  by  Apellis  under  Section  2.1.1  (License  Grants  to  Sobi)  to  Third  Parties  for  the  purpose  of
Developing, Manufacturing, Commercializing or conducting Medical Affairs with respect to any Product in
the Sobi Territory, but:

(i)

(ii)

Sobi may not sublicense any right to Commercialize any Product in any Major European Country
without Apellis’ prior written approval (which may not be unreasonably withheld, conditioned, or
delayed); and

Sobi may not sublicense any right to Commercialize any Product in any Major Market or Russia
without first giving Apellis opportunity to comment on Sobi’s proposed sublicensee.

Subject  to  Section  2.5.2(f)  (Sublicenses),  Apellis  will  have  the  right  to  sublicense  any  or  all  of  the  rights

Product  in  the  Apellis  Territory  or  Developing,  Manufacturing,  Commercializing,  or  conducting  Medical
Affairs with respect to Non-Systemic Ophthalmology Products anywhere in the world.

If Sobi sublicenses to any Third Party any of the Commercialization rights granted to it by Apellis under this
Agreement  and  such  sublicense  includes  any  rights  licensed  under  the  Penn  Other  Fields  License,  Apellis
and  Sobi  shall  jointly  notify  Penn  of  the  identity  of  such  Sublicensee  within  [**]  after  the  grant  of  such
sublicense.

A Party sublicensing any of the rights granted to it by the other Party under this Agreement shall ensure that
each of its sublicensees is bound by a written agreement that is consistent with, and subject to the applicable
terms  and  conditions  of,  this  Agreement,  and  such  sublicensing  Party  shall  provide  the  other  Party  with  a
copy of such sublicense agreement within [**] after the execution of such sublicense agreement.  Any such
copy  may  be  reasonably  redacted  to  the  extent  required  to  remove  any  confidential,  proprietary,  or
competitive

31

 
 
 
 
 
 
 
 
 
 
information,  but  such  copy  shall  not  be  redacted  to  the  extent  that  it  impairs  the  other  Party’s  ability  to
monitor compliance with this Agreement, unless such redaction is required to prevent breach of the terms of
such  sublicense  or  other  confidentiality  obligation  to  which  the  relevant  Party  or  its  Affiliates  is  subject.
Such  sublicense  agreement  shall  be  treated  as  Confidential  Information  of  the  sublicensing  Party.    Each
sublicensing Party will be responsible, and primarily liable, for the performance of each of its sublicensees
with all relevant restrictions, limitations, and obligations in this Agreement, and the grant of any sublicense
will not relieve either Party of its obligations under this Agreement. Without limiting the foregoing, unless
otherwise agreed by the Parties in advance in writing:

(i)

(ii)

the  sublicensing  Party  shall  require  any  Third  Party  to  whom  such  Party  discloses  Confidential
Information  of  the  other  Party  to  enter  into  an  appropriate  written  agreement  obligating  such
Third  Party  to  be  bound  by  obligations  of  confidentiality  and  restrictions  on  use  of  such
Confidential Information that are at least as protective of such Confidential Information as are the
obligations set forth in Article 13 (Confidentiality), including requiring such Third Party to agree
in  writing  not  to  issue  any  publications  concerning  any  Compound  or  Product  except  in
compliance with the terms of this Agreement; and

the sublicensing Party shall obligate its sublicensees to agree in writing to assign ownership to the
sublicensing  Party  of,  or  grant  an  exclusive,  royalty-free,  worldwide,  perpetual,  and  irrevocable
license  (with  the  right  to  freely  grant  sublicenses  through  multiple  tiers)  to,  all  Collaboration
Know-How and Collaboration Patent Rights arising under its agreement with such Third Party to
the extent related to the Exploitation of any Compound or Product, and such sublicensing Party
shall structure each such assignment or exclusive license so as to enable such sublicensing Party
to license or sublicense (as applicable) such Collaboration Know-How and Collaboration Patent
Rights to the other Party in accordance with this Agreement.

2.6

Exclusivity

.  During the Term, with respect to each Initial Indication and each other Indication that the JEC mutually agrees to include in the
Global Development Plan, on an Indication-by-Indication basis, Apellis covenants and agrees that neither Apellis nor any of its Affiliates
shall, directly or indirectly, alone or with or for any Third Party (including, for clarity, by grant of a license to or entry into any agreement or
other arrangement with a Third Party in connection with the same), conduct any clinical Development or Clinical Trial or Commercialize any
pharmaceutical product containing, incorporating, or comprising APL-9 (alone or in combination), for the treatment of such Indication unless
and  until  the  JEC  unanimously  agrees  that  the  Parties  will  no  longer  Develop  or  Commercialize  Products  for  such  Indication  under  this
Agreement in accordance with Section 3.2.3(i) (Responsibilities). Each of the Parties recognizes that the restrictions contained in, and the
terms  of,  this  Section2.6  (Exclusivity)  are  required  for  the  protection  of  Sobi’s  exclusive  rights  under  the  License  and  Apellis’  royalties
hereunder, and agrees that, if any provision in this Section 2.6 (Exclusivity) is determined by any court to be unenforceable by reason of its
extending for too great a period of time or over too great a geographic area, or by reason of its being too extensive in any other respect, such
covenant shall be interpreted to extend only for the longest period of time and over the greatest geographic area, and to otherwise have the
broadest application as shall be enforceable under Applicable Law.

using  methods  commonly  used  in  the  industry  for  such  purpose,  and  the  Parties  shall  keep  each  other  reasonably
informed of any such exports or resales of which they become aware.

Commercialize  any  Product  in  the  Sobi  Territory,  Apellis  shall  notify  Sobi  thereof,  shall  not  accept  such  request  or
order, and shall direct the relevant individual or entity to Sobi.

her responsibilities on the JEC. Each Party shall provide written notice (including via email notification) to the other
Party  or  the  other  Party’s  Alliance  Manager  of  its  initial  representatives  to  the  JEC.    Each  Party’s  Chief  Executive

Chief Executive Officer during the first [**] after the Effective Date, either Party may replace its JEC representatives
with similarly qualified individuals at any time upon prior written notice (including via email notification) to the other

Parties to participate in the discussions and meetings of the JEC, but such participants will have no voting authority at
the  JEC.  Each  Party  shall  ensure  that  all  of  its  JEC  members,  and  all  of  its  non-member  employees  and  all  non-
employee Third Parties attending any JEC meeting, are bound by

34

 
 
 
 
 
 
 
 
 
 
3.2.2

obligations of non-use and confidentiality that are at least as protective of the other Party’s Confidential Information as
are those set forth in Article 13 (Confidentiality).  The Alliance Managers shall be responsible, on behalf of the JEC, for
setting the agenda for meetings of the JEC with input from the JEC members and will disseminate such agendas and
presentations to be made at any meeting no later than [**] in advance of each JEC meeting unless otherwise agreed to
by the Parties in writing.

Meetings.    The  JEC  shall  meet  in  person  (alternating  between  a  site  designated  by  each  of  Apellis  and  Sobi)  or  by
videoconference or teleconference at least [**] until the earliest of (a) [**], (b) a Change of Control of either Party, or
(c) [**], and thereafter shall meet [**] or with such other frequency as the Parties may agree. Specific meeting dates
shall  be  determined  by  agreement  of  the  Parties.    Either  Party  may  also  call  a  special  meeting  of  the  JEC  (by
videoconference or teleconference) upon prior written notice to the other Party if such Party reasonably believes that a
significant matter must be addressed before the next regularly scheduled JEC meeting, and such Party shall provide the
JEC with materials reasonably adequate to enable an informed discussion by its members before such special meeting.
Apellis  shall  host  the  first  meeting  of  the  JEC  at  a  mutually  agreeable  time  and  place  no  later  than  [**]  after  the
Effective Date.  Each Party will be responsible for its own expenses relating to attendance at or participation in JEC
meetings.    Each  Party  shall  appoint  one  of  its  JEC  representatives  to  act  as  a  co-chairperson  of  the  JEC.    The
responsibility for running each JEC meeting will alternate between the JEC co-chairpersons from meeting-to-meeting,
with Apellis’ co-chairperson running the first JEC meeting.  The JEC co-chairpersons (or, at the election of the JEC co-
chairpersons,  the  Alliance  Managers)  shall  jointly  prepare  and  circulate  agendas  to  JEC  representatives  at  least  [**]
before each JEC meeting (other than a special meeting as described above) and shall direct the preparation of meeting
minutes  after  each  JEC  meeting,  which  shall  be  approved  by  the  JEC  co-chairpersons  and  circulated  to  other  JEC

3.2.4

Subcommittees.  

(a)

The JEC may, by unanimous agreement, establish and delegate specifically-defined duties to subcommittees
and other operational committees or ad-hoc

36

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
subcommittees on an “as-needed” basis to review, discuss, and, as applicable, oversee particular projects or
activities.    The  initial  subcommittees  of  the  JEC  will  be  the  Joint  Development  Committee  (“JDC”),  the
Joint  Medical  Committee  (“JMC”),  the  Joint  Commercialization  Committee  (“JCC”),  and  the  Joint
Manufacturing  and  Supply  Committee  (“JMSC”).    The  JEC  may,  by  unanimous  agreement,  disband  such
subcommittees as deemed necessary by the JEC.  Each such subcommittee shall consist of the same number
of representatives designated by each Party, which number shall be agreed upon by the Parties.  Each Party
will be free to change its subcommittee representatives upon written notice to the other Party or by sending a
substitute representative to any subcommittee meeting, but each Party shall ensure that, at all times during
the  existence  of  any  subcommittee,  such  Party  has  appropriate  representatives  on  such  subcommittee  in
terms of experience, expertise, and seniority for the then-current stage of Development or Commercialization
of the Products and the authority to bind such Party with respect to matters within the purview of the relevant
subcommittee.    Each  Party  shall  ensure  that  its  subcommittee  representatives  and  any  substitutes  therefor,
and  any  other  individual  attending  any  subcommittee  meeting  on  such  Party’s  behalf,  shall  be  bound  by
obligations  of  non-use  and  confidentiality  that  are  at  least  as  protective  of  the  other  Party’s  Confidential
Information as are those set forth in Article 13 (Confidentiality).  The Alliance Managers of each Party (or
their  designees)  shall  attend  each  meeting  of  each  subcommittee  as  non-voting  participants.  Except  as
expressly provided in this Agreement, no subcommittee will have the authority to bind the Parties hereunder,
and each subcommittee shall report to, and have any disputes in such committee resolved by, the JEC.  No
subcommittee’s  authority  may  exceed  the  authority  specified  for  such  subcommittee  in  this  Article  3
(Governance).  Any  disagreement  between  the  representatives  of  the  Parties  on  a  subcommittee  shall  be
referred to the JEC for resolution in accordance with Section 3.7.2 (Escalation to JEC).

Unless  otherwise  previously  agreed  in  writing  by  the  Alliance  Managers  or  otherwise  set  out  in  this
Agreement,  the  JDC  shall  meet  [**]  until  the  earlier  of  (A)  [**]  or  (B)  [**],  and  otherwise  each
subcommittee shall meet at least [**] until the earliest of (i) [**], (ii) a Change of Control of either Party, or
(iii) [**], and thereafter shall meet [**] at a time agreed by the Parties, spaced at regular intervals unless the
Parties agree in writing to a different frequency, with the location for such meetings to be determined by such
subcommittee.  Each subcommittee may meet in person, or alternatively, such subcommittee may meet by
means  of  teleconference,  videoconference,  or  other  similar  communications  equipment.    Either  Party  may
also call a special meeting of each subcommittee by prior written notice to the other Party in the event such
requesting Party reasonably believes that a significant matter must be addressed prior to the next scheduled
meeting,  and  such  requesting  Party  shall  provide  such  subcommittee,  prior  to  the  special  meeting,  with
materials reasonably adequate to enable an informed decision on the relevant matter.  No later than [**] prior
to any meeting of any subcommittee (other than a special meeting as described above), a designated member
of such subcommittee or, if such subcommittee so agrees, one of the Alliance Managers shall prepare and
circulate an agenda for such meeting to all members of such subcommittee, but either Party will be free to
propose additional topics to be included on such agenda, either prior to or during the course of such meeting.
Each  Party  will  bear  the  expense  of  its  respective  subcommittee  members’  participation  in  subcommittee
meetings.  A designated member of each subcommittee or, if such

37

(b)

 
 
 
 
subcommittee so agrees, one of the Alliance Managers shall be responsible for keeping written minutes of all
such  subcommittee’s  meetings  that  reflect  all  decisions  made  at  such  meetings.    Such  designated
subcommittee  member  or  Alliance  Manager  shall  send  meeting  minutes  to  each  member  of  such
subcommittee for review and approval within [**] after each meeting of such subcommittee.  Such minutes
will be deemed approved unless, through communication of the Alliance Managers, one or more members of
such subcommittee objects to the accuracy of such minutes within [**] after receipt. Except as expressly set
forth in this Section 3.2.4(b) (Subcommittees), no designated member of any subcommittee shall have any
rights or powers greater than those of any other member of such subcommittee.

or  Committee  meetings,  by  a  Party  representative  shall,  at  the  election  of  either  Party,  be  submitted  to  the  JEC  for
resolution.  If the JEC is unable to resolve any such disagreement referred to it by the JDC, JMC, JCC, JMSC, or any
other  subcommittee,  or  any  disagreement  with  respect  to  the  matters  within  the  scope  of  the  JEC’s  authority  or  any
other dispute between the Parties that may be referred to the JEC, in each case, using good faith efforts within a period
of [**] from such referral or the start of such disagreement, as applicable, then either Party may immediately refer such
matter  for  resolution  to  the  Chief  Executive  Officer  of  Apellis  and  the  Chief  Executive  Officer  of  Sobi,  or  their
respective  designees  from  senior  management  with  decision-making  authority  over  such  matter  (such  executives  or

3.7.4

Escalation to Executives.  In the event that the Executive Officers are unable to resolve any dispute referred to them

(b)

No  Change;  Status  Quo.    Neither  Party  will  have  final  decision-making  authority  over  the  following
matters, and all such matters must be decided by unanimous agreement in order to take any action or adopt
any change from the then-current status quo: (i) any change or update to the Global Development Plan or
Global Development Budget, (ii) adoption of, or any change or update to, the Global Branding Strategy, (iii)
adoption of, or any change or update to, the Medical Affairs Strategy, or (iv) the approval or coordination of
or any change or update to the Apellis Readiness Activities.

Other Decisions.  With respect to any matter not described in Section 3.7.4(a) (No Change; Status Quo), the
Party specified below shall, subject to Section 3.7.5 (Limitations on Decision Making Authority), except to
the  extent  otherwise  specified  in  this  Agreement,  have  final  decision-making  authority  with  respect  to  the
matters specified below, but any such decision must be (to the extent applicable) (i) consistent with the then-
current Global Development Plan and corresponding Global Development Budget (except that Apellis (but

set  forth  in  the  initial  Global  Development  Plan  attached  to  this  Agreement)  and  the  Medical  Affairs
Strategy,  (ii)  subject  to  Section  6.1  (Overview),  in  accordance  with  the  then-current  Global  Branding

4.4.4

Additional  Development.    If  either  Party  (a  “Proposing  Party”  for  the  purposes  of  this  Section  4.4.4  (Additional
Development)) desires to perform, for any Product, any Clinical Trial that is not already set forth in the then-current
Global Development Plan (“Additional Development”), then such Proposing Party shall present to the JDC to review,
discuss, and determine whether to approve a proposal to add such Additional Development to the Global Development
Plan  (each  such  proposal,  an  “Additional  Development  Proposal”).  Each  Additional  Development  Proposal  shall
describe  in  reasonable  detail  the  proposed  additional  Development  activities  (the  “Additional  Development
Activities”), including, as applicable, any non-clinical studies, GLP Toxicology Studies, clinical studies, and Clinical
Trials, that the Proposing Party desires to conduct or have conducted as part of such Additional Development, including
a synopsis of the Clinical Trials or activities, the proposed enrollment criteria, the number of patients to be included, the
endpoints to be measured, and the statistical design and powering, as well as a proposed timeline and budget and an
analysis of the business opportunity and revenue potential for such Additional Development Activities.  

(a)

JEC Decision Regarding Additional Development Activities. The JDC shall review, discuss, and submit
to  the  JEC  to  review,  discuss,  and  determine  whether  to  approve  each  Additional  Development  Proposal
within [**] after receipt thereof from the Proposing Party.

(i)

(ii)

JEC Approval.    If  the  JEC  unanimously  approves  an  Additional  Development  Proposal,  then,
upon  such  an  approval,  (A)  the  Additional  Development  Activities  set  forth  in  such  Additional
Development Proposal will be “Additional Global Development Activities” for purposes of this
Agreement, and (B) the JDC will update the Global Development Plan to include such Additional
Global Development Activities as set forth in the applicable Additional Development Proposal (as
may be amended by the JEC upon such approval) and submit such updated Global Development
Plan to the JEC for review, discussion, and approval.

No  Approval.  If  the  JEC  does  not  approve  an  Additional  Development  Proposal,  then  the
Additional  Development  Activities  proposed  in  such  Additional  Development  Proposal  will  not
be included in the Global Development Plan, and (A) if the JEC does not approve an Additional
Development Proposal because one Party has a reasonable, good faith concern that the proposed
Additional Development Activities raise material safety or scientific concerns, then neither Party
may  conduct  the  proposed  Additional  Development  Activities  unless  and  until  (1)  the  Parties
agree otherwise or (2) a neutral safety committee engaged by the Parties pursuant to Section 16.4
(Neutral Safety Committee) approves such Additional Development Activities, and (B) if the JEC
does not approve an Additional Development Proposal for any reason other than those set forth in
Section 4.4.4(a)(ii)(A) (No Approval), Section 4.4.4(b) (Performance of Unilateral Development
Activities) will apply.

(b)

Performance of Unilateral Development Activities.

(i)

Unilateral  Development  Activities.  If,  for  any  reason  other  than  those  set  forth  in  Section
4.4.4(a)(ii)(A) (No Approval), the JEC does not approve

49

 
 
 
 
 
 
 
 
(ii)

an  Additional  Development  Proposal,  then  the  Proposing  Party  may,  upon  notice  to  the  other
Party  (the  “Non-Proposing  Party”  for  the  purposes  of  this  Section  4.4.4  (Additional
Development)),  subject  to  Section  4.7  (Clinical  Trials),  conduct  the  Additional  Development
Activities  set  forth  in  such  Additional  Development  Proposal  at  its  own  cost  and  expense  in  a
manner and timeline determined by such Party and pursuant to any protocol for such Additional
Development  Activities  determined  by  such  Party;  except  that  (A)  if  Apellis  is  the  Party
conducting  the  Additional  Development  Activities,  then  Apellis  may  not,  without  Sobi’s  prior
written  consent,  conduct  such  Additional  Development  Activities  in  the  Major  Markets  (other
than [**])  and  (B)  if  Sobi  is  the  Party  conducting  the  Additional  Development  Activities,  then
Sobi  may  not,  without  Apellis’  prior  written  consent,  (I)  conduct  such  Additional  Development
Activities  for  any  ophthalmology  Indication  or  (II)  conduct  such  Additional  Development
Activities  in  the  Apellis  Territory.  If  the  Proposing  Party  elects  to  conduct  any  Additional
Development  Activities  under  any  Additional  Development  Proposal  in  accordance  with  the
terms  of  this  Section  4.4.4(b)(i)  (Unilateral  Development  Activities),  then  all  such  Additional
Development  Activities  will  be  “Unilateral  Development  Activities”  for  purposes  of  this
Agreement.

Unilateral  Development  Data.  Notwithstanding  any  provision  to  the  contrary  set  forth  in  this
Agreement,  except  as  expressly  set  forth  in  this  Section  4.4.4(b)(ii)  (Unilateral  Development
Data) or Section 4.4.4(b)(iii) (Buy-In), the Non-Proposing Party shall have no rights with respect
to, and may not use or reference, any data (including preclinical, nonclinical, clinical, technical,
chemical, safety and scientific data and information) or other results generated by, resulting from,
or in connection with the conduct of any Unilateral Development Activities (such data and results,
“Unilateral Development Data”) in any Regulatory Submission in support of a label expansion
or  to  obtain  a  new  Indication  for  the  Product  in  such  Party’s  territory;  provided  however  that,
without  limiting  the  foregoing  and  notwithstanding  anything  to  the  contrary  in  this  Agreement
(including this Section 4.4.4(b)(ii) (Unilateral Development Data)), each Party shall have the right
to use any Unilateral Development Data as reasonably necessary to address issues relating to the
safety (including modifications to product labelling as deemed reasonably necessary by a Party)
of Products, or (solely with respect to Apellis) Non-Systemic Ophthalmology Products, when and
as  such  data  become  available.  Notwithstanding  the  foregoing,  any  Unilateral  Development
Activities  that  consist  solely  of  an  investigator-sponsored  clinical  study  shall  not  be  considered
“Unilateral  Development  Activities”  for  the  purposes  of  this  Section  4.4.4(b)(ii)  (Unilateral
Development  Data)  and  Section  4.4.4(b)(iii)  (Buy-In),  and  all  data,  results,  and  information
generated by, resulting from, or in connection with the conduct of the same may be used by the
Non-Proposing  Party  to  the  full  extent  of  the  license  granted  to  such  Non-Proposing  Party  in
Section 2.1.1 (License Grants to Sobi) or Section 2.1.2 (License Grants to Apellis), as applicable,
and  the  right  of  reference  granted  to  such  Non-Proposing  Party  in  Section  5.3  (Right  of
Reference).

50

 
 
 
 
(iii)

Buy-In.  If  at  any  time  a  Non-Proposing  Party  desires  to  obtain  rights  to,  use,  or  reference  any
Unilateral  Development  Data  from  any  Unilateral  Development  Activities,  then  such  Non-
Proposing  Party  may  notify  the  Proposing  Party  of  such  desire  in  writing.  Upon  receipt  of  any
such notice, the Proposing Party will promptly provide to the Non-Proposing Party written notice
of all reasonable costs and expenses incurred by such Proposing Party in the performance of such
Unilateral  Development  Activities  as  of  the  date  of  such  notice,  including,  as  applicable,  all
Manufacturing Costs incurred or paid under this Agreement or the Supply Agreement to obtain
Products  for  such  Unilateral  Development  Activities  (a  “Unilateral  Development  Notice”  and
such  costs  the  “Unilateral  Additional  Development  Costs”).  Within  [**]  after  receipt  of  any
Unilateral Development Notice, the Non-Proposing Party may reimburse the Proposing Party for
[**]  percent  ([**]%)  of  the  Unilateral  Additional  Development  Costs  contained  therein  that
would have been paid by such Non-Proposing Party had such Unilateral Development Activities
always  been  Additional  Global  Activities.  If  the  Non-Proposing  Party  so  reimburses  the
Proposing  Party,  then,  from  and  after  the  date  on  which  the  Proposing  Party  received  the  Non-
Proposing  Party’s  notice  requesting  rights  to,  or  the  right  to  use  or  reference,  any  Unilateral
Development  Data  from  any  Unilateral  Development  Activities,  (A)  the  data  and  other  results
generated  from  such  Unilateral  Development  Activities  shall  be  deemed  to  no  longer  be
Unilateral  Development  Data  and  shall  be  deemed  to  be  included  in  the  licenses  granted  under
Section 2.1.1 (License Grants to Sobi) or Section 2.1.2 (License Grants to Apellis), as applicable,
and the right of reference granted in Section 5.3 (Right of Reference), and (B) if such Unilateral
Development Activities are still ongoing, then (I) such activities shall be deemed to no longer be
Unilateral  Development  Activities,  (II)  such  activities  shall  be  deemed  to  be  Additional  Global
Development  Activities,  (III)  Section  4.4.4(a)(i)  (JEC  Approval)  shall  apply  to  such  Additional
Global  Development  Activities,  and  (IV)  the  Parties  shall  share  all  Shared  Development  Costs
incurred  as  a  result  of  such  Additional  Global  Development  Activities  pursuant  to  Section  4.6
(Development  Costs)  going  forward.  This  Section  4.4.4(b)(iii)  (Buy-In)  shall  survive  any
expiration or termination of this Agreement and, for clarity, no Unilateral Development Data shall
be included within the Reversion Technology other than in accordance with this Section 4.4.4(b)
(iii) (Buy-In).

4.4.5

Global  Development  Budget.  The  initial  Global  Development  Budget  is  attached  hereto  in  Schedule  4.4.1  (Initial
Global  Development  Plan  and  Initial  Global  Development  Budget).  Subsequent  Global  Development  Budgets  will
consist of a detailed written budget, broken down on a [**] basis, for the performance of those activities allocated to
each Party under the Global Development Plan for the [**], which budget will include the Development FTE Costs to
be  incurred  by  each  Party  in  performing  each  of  the  Global  Development  Activities  under  the  Global  Development
Plan,  as  well  as  any  direct  Out-of-Pocket  Costs  expected  to  be  incurred  in  connection  with  the  performance  of  the
Global  Development  Activities  under  the  Global  Development  Plan  and  all  Manufacturing  Costs  associated  with  the
Manufacture of the Products for purposes of performing the applicable Global Development Activities.

4.4.6

Updating  the  Global  Development  Plan. In  addition  to  updates  made  in  accordance  with  Section  4.4.4 (Additional
Development), at least [**] during the Term (or more frequently as may be required or as may be reasonably requested
by  either  Party),  the  JDC  shall  review  and  update  the  Global  Development  Plan,  and  the  corresponding  Global
Development Budget, based on currently available information and data. The JDC shall review, discuss, and determine
whether to approve any such update to the Global Development Plan, and shall submit to the JEC to review, discuss,
and determine whether to approve any such update to the Global Development Plan or Global Development Budget set
forth therein, in each case, that is material. Each such update to the Global Development Plan and  the  corresponding
Global Development Budget will become effective and will supersede the previous Global Development Plan and the
corresponding Global Development Budget upon approval thereof by the JDC, and, if applicable, the JEC.

4.5

Development Step-In Right

.  If (a) either Party materially breaches its obligation under Section 4.3 (Development Diligence Obligations) (excluding Section
4.3.3 (Development Diligence Obligations)) to use Commercially Reasonable Efforts to perform any of the Global Development Activities
allocated to such party under the Global Development Plan for any Product within the timelines specified therein or otherwise in accordance
with the Global Development Plan or (b) Apellis materially breaches its obligations under Section 2.4 (Technology, Data, and Regulatory
Transfer)  and,  in  each  case  ((a)  or  (b))  such  material  breach  remains  uncured  for  [**]  measured  from  the  date  of  such  Party’s  receipt  of
written notice of such material breach from the other Party that identifies the material breach, then (x) with respect to a material breach by a
Party  of  Section  4.3  (Development  Diligence  Obligations)  (excluding  Section  4.3.3  (Development  Diligence  Obligations)),  upon  written
notice  to  such  Party,  the  other  Party  may  assume  responsibility  for  the  applicable  Global  Development  Activities  or  (y)  with  respect  to  a
breach of Section 2.4 (Technology, Data, and Regulatory Transfer) by Apellis, Sobi may perform such activities as it reasonably determines
are necessary to produce or recreate the items which have not been transferred, including sponsoring Clinical Trials to produce equivalent
data  for  use  in  Regulatory  Submissions; but,  if  such  breach  is  not  susceptible  of  cure  within  such  [**]  cure  period  even  with  the  use  of
Commercially Reasonable Efforts, the non-breaching Party’s right to assume responsibility for such Global Development Activities shall be
suspended by up to an additional [**] period if and for so long as the breaching Party has provided to the non-breaching Party a reasonable
written  plan,  calculated  to  effect  a  cure  of  such  breach,  and  commits  to  and  is  diligently  performing  such  plan.  If  Sobi  assumes  any  of
Apellis’  Global  Development  Activity  responsibilities  pursuant  to  this  Section  4.5  (Development  Step-In  Right),  then,  notwithstanding
anything  to  the  contrary  in  this  Agreement,  Apellis  shall  reimburse  Sobi  for  [**]  percent  ([**]  %)  of  all  Development  FTE  Costs,
Manufacturing Costs, and Out-of-Pocket Costs incurred by Sobi in conducting such Global Development Activities. If Apellis assumes any
of Sobi’s Global Development Activity responsibilities pursuant to this Section 4.5 (Development Step-In Right), such assumption shall not
affect Sobi’s responsibility (if any) for the costs and expenses of such Global Development Activities. The remedies provided in this Section

Development Costs

.

4.6.1

Initial  Development  Costs.  Without  limiting  Sobi’s  obligation  to  pay  Apellis  the  Development  Reimbursement
Payments pursuant to Section 9.2 (Development Reimbursement Payments), Apellis shall be solely responsible for all
Development FTE Costs, Manufacturing Costs, and Out-of-Pocket Costs (including, for clarity any costs of supplying
placebo) incurred by a Party or any of its Affiliates in accordance with the initial

52

 
 
 
 
Global Development Plan and associated Global Development Budget attached to this Agreement or incurred Apellis or
any  of  its  Affiliates  in  performing  the  Apellis  Readiness  Activities  (the  “Initial  Development  Costs”),  and  shall
reimburse Sobi for any Initial Development Costs that are not disputed in good faith that are incurred by Sobi or any of
its Affiliates in conducting activities allocated to Sobi in the then-current Global Development Plan, and conducted in
accordance  with  the  then-current  Global  Development  Plan  and  associated  Global  Development  Budget,  within  [**]
after  receipt  of  any  invoice  therefor.  For  the  avoidance  of  doubt,  Apellis  shall  not  be  responsible  for  any  costs  or
expenses (including Development FTE Costs and Out-of-Pocket Costs) incurred by Sobi or any of its Affiliates that are
not in accordance with the then-current Global Development Budget.

PNH  Development  Costs.  Apellis  shall  be  solely  responsible  for  all  reasonable  Development  FTE  Costs,
Manufacturing  Costs,  and  Out-of-Pocket  Costs  (including,  for  clarity  any  costs  of  supplying  placebo)  incurred  by  a
Party  or  any  of  its  Affiliates  in  conducting  activities  required  to  be  added  to  the  Global  Development  Plan  (and
associated  Global  Development  Budget)  by  the  JEC  (or  baseball  arbitration),  in  accordance  with  Section  3.2.3(j)
(Responsibilities),  as  a  result  of  a  conditional  Regulatory  Approval  in  PNH  in  the  European  Union  and  the  United
Kingdom  (“PNH  Development  Costs”),  and  shall  reimburse  Sobi  for  any  undisputed  PNH  Development  Costs
incurred  by  Sobi  or  any  of  its  Affiliates  in  conducting  activities  allocated  to  Sobi  in  the  then-current  Global
Development Plan, and conducted in accordance with the then-current Global Development Plan and associated Global
Development Budget, within [**] after receipt of any invoice therefor. For the avoidance of doubt, Apellis shall not be
responsible for any costs or expenses (including Development FTE Costs and Out-of-Pocket Costs) incurred by Sobi or
any of its Affiliates that are not in accordance with the then-current Global Development Budget.

Shared  Development  Costs.  Except  for  Initial  Development  Costs  or  PNH  Development  Costs,  and  except  as
otherwise unanimously agreed by the JEC in accordance with Section 3.2.3(k) (Responsibilities), each Party shall bear
fifty percent (50%) of all Development FTE Costs, Manufacturing Costs, and Out-of-Pocket Costs incurred by a Party
or any of its Affiliates in accordance with the Global Development Plan and associated Global Development Budget, as
well  as  all  costs  set  forth  in  Section  5.5.2(a)  (Cost  Allocation)  (collectively,  the  “Shared  Development  Costs”).
Following each [**] in which either Party incurs any Shared Development Costs, such Party will provide to the other
Party a written report of the Shared Development Costs incurred by or on behalf of such Party and, no later than [**]
after receipt of each such written report, the applicable Party will make a balancing payment to the other Party such that
each Party pays its share of all undisputed Shared Development Costs. For the avoidance of doubt, neither Party shall
be responsible for any costs or expenses (including Development FTE Costs and Out-of-Pocket Costs) incurred by the
other Party or any of its Affiliates that are not in accordance with the then-current Global Development Budget.

Other  Costs.    Subject  to  the  terms  of  the  Supply  Agreement,  each  Party  shall  solely  bear  all  costs  and  expenses
incurred by such Party or its Affiliates in Developing Products that do not qualify as Initial Development Costs, Shared
Development Costs, PNH Development Costs, or Manufacturing Process Costs. Without limiting the foregoing, Apellis
shall solely bear all costs and expenses incurred by Apellis in conducting the Apellis Territory Regional Development
Activities, and Sobi shall solely bear all costs and expenses incurred by Sobi in conducting the Sobi Territory Regional
Development Activities (including all Manufacturing Costs paid by Sobi to Apellis pursuant to the

through the JDC, review, discuss, and approve the protocol(s) and statistical analysis plan(s) for such Clinical Trial, in
accordance with Section 3.3.2(h) (Specific Responsibilities of the JDC). Such review, discussion, and approval shall not
be limited to quarterly JDC meetings, but rather shall occur on the timelines, and at the frequencies, needed to ensure
that each Clinical Trial can be started and conducted on a reasonable timeline.

Restriction on Location of Clinical Trials. Without limiting any other provision of this Agreement, Apellis may not
conduct any Clinical Trial (for the avoidance of doubt, excluding any Clinical Trial that is ongoing in the applicable
country(ies) as of the Effective Date) for a Product in a Major Market (other than [**]) without the prior written consent
of Sobi (such consent not to be unreasonably withheld, conditioned, or delayed), and Sobi may not conduct any Clinical
Trial  for  a  Product  in  the  Apellis  Territory  without  the  prior  written  consent  of  Apellis  (such  consent  not  to  be
unreasonably withheld, conditioned, or delayed).

Cooperation and Coordination. If Apellis or an Affiliate of Apellis conducts a clinical study or Clinical Trial in the
Sobi  Territory,  or  Sobi  or  an  Affiliate  of  Sobi  conducts  a  clinical  study  or  Clinical  Trial  in  the  Apellis  Territory,  as
permitted under this Agreement, the Parties shall reasonably cooperate and coordinate with each other with regard to
the conduct and enrollment of such clinical study or Clinical Trial and, following completion of such clinical study or
Clinical Trial, to the extent permitted by Applicable Law, shall use Commercially Reasonable Efforts to facilitate the

4.8.1

Combination  Therapy  Development.    If  either  Party  (a  “Proposing  Party”  for  the  purposes  of  this  Section  4.8.1
(Combination Therapy Development)) desires to conduct any Development of any Combination Product or any Product
as a combination therapy with any other pharmaceutical product other than in the form of a Combination Product (e.g.,
where a Product is administered sequentially or co-administrated with one (1) or more other pharmaceutical products,
but is not co-formulated or co-packaged with any other pharmaceutical product) in order to obtain Regulatory Approval
for  such  Combination  Product  or  combination 
the
therapy 
Regulatory/Reimbursement Responsible Party (any such Development, “Combination Therapy Development”), such
Party  shall,  at  least  [**]  prior  to  commencing  such  Combination  Therapy  Development,  notify  the  other  Party  (the
“Non-Proposing Party”  for  the  purposes  of  this  Section  4.8.1  (Combination  Therapy  Development))  via  the  JDC  of
such proposed Development (each a “Combination Therapy Development Proposal”) including in reasonable detail
the  proposed  Combination  Therapy  Development  activities  (the  “Combination  Therapy  Development  Activities”),
including, as applicable, any non-clinical studies, clinical studies, GLP Toxicology Studies, and Clinical Trials that the
Proposing Party desires to conduct or have conducted as part of such Combination Therapy

in  which  such  Party 

in  any  country 

is

patients  to  be  included,  the  endpoints  to  be  measured,  and  the  statistical  design  and  powering,  as  well  as  a  proposed
timeline and budget and an analysis of the business opportunity and revenue potential for such Combination Therapy
Development Activities.

(a)

JEC Decision Regarding Combination Therapy Development Activities. The JDC shall review, discuss,
and submit to the JEC to review, discuss, and determine whether to approve each Additional Development
Proposal within [**] after receipt thereof from the Proposing Party.

(i)

(ii)

JEC  Approval.    If  the  JEC  unanimously  approves  a  Combination  Therapy  Development
Proposal, then, upon such an approval, (A) the Combination Therapy Development Activities set
forth  in  such  Combination  Therapy  Development  Proposal  will  be  “Combination  Therapy
Global  Development  Activities”  for  purposes  of  this  Agreement,  (B)  the  JDC  will  update  the
Global Development Plan to include such Combination Therapy Global Development Activities
as set forth in the applicable Combination Therapy Development Proposal (as may be amended
by the JEC upon such approval) and submit such updated Global Development Plan to the JEC
for review, discussion, and approval; and (C) the Parties shall share all Shared Development Costs
incurred  as  a  result  of  such  Combination  Therapy  Global  Development  Activities  pursuant  to

No Approval. If the JEC does not approve a Combination Therapy Development Proposal, then
the  Combination  Therapy  Development  Activities  proposed  in  such  Combination  Therapy
Development Proposal will not be included in the Global Development Plan, and (A) if the JEC
does  not  approve  an  Combination  Therapy  Development  Proposal  because  one  Party  has  a
reasonable,  good  faith  concern  that  the  proposed  Combination  Therapy  Development  Activities
raise  material  safety  or  scientific  concerns,  then  neither  Party  may  conduct  the  proposed
Combination Therapy Development Activities unless and until (1) the Parties agree otherwise or
(2)  a  neutral  safety  committee  engaged  by  the  Parties  pursuant  to  Section  16.4  (Neutral  Safety
Committee)  approves  such  Additional  Development  Activities,  and  (B)  if  the  JEC  does  not
approve an Additional Development Proposal for any reason other than those set forth in Section
4.8.1(a)(ii)(A) (No Approval), Section 4.8.1(b) (Performance of Unilateral Combination Therapy
Development Activities) will apply.

(b)

Performance of Unilateral Combination Therapy Development Activities. If, for any reason other than
those set forth in Section 4.8.1(a)(ii)(A) (No Approval), the JDC does not unanimously determine to include,
or the JEC does not unanimously confirm inclusion of, any given Combination Therapy Development in the
Global Development Plan, then the Proposing Party may, upon notice to the Non-Proposing Party, conduct
such  Combination  Therapy  Development  at  its  own  cost  and  expense  in  accordance  with  the  terms  and
conditions of this Agreement (each a “Unilateral Combination Therapy Development Activity”);  except
that:

conditioned,  or  delayed),  (i)  conduct  any  Unilateral  Combination  Therapy  Development
Activities  in  the  Apellis  Territory  or  (ii)  conduct  any  Unilateral  Combination  Therapy
Development Activities for any ophthalmology indication; and

for [**] after the Proposing Party notifies the Non-Proposing Party that the Proposing Party will
be conducting any Unilateral Combination Therapy Development Activities in the other Party’s
territory,  the  Parties  shall  negotiate  in  good  faith  a  Clinical  Trial  Collaboration  and  Supply
Agreement with respect to such Combination Therapy Development, but nothing in this Section
4.8.1(b) (No Inclusion in the Global Development) shall require either Party to enter into any such
Clinical Trial Collaboration and Supply Agreement.

(iv)

If the Parties fail to enter into such a Clinical Trial Collaboration and Supply Agreement within
such [**] period the following terms shall apply:

A.

B.

all data, results, and information generated by, resulting from, or in
connection with the conduct of any applicable Unilateral Combination
Therapy Development Activities (the “Combination Therapy Data”) may
be used by the Non-Proposing Party to the full extent of the license granted
to such Non-Proposing Party in Section 2.1.1 (License Grants to Sobi) or
Section 2.1.2 (License Grants to Apellis), as applicable, and the right of
reference granted to such Non-Proposing Party in Section 5.3 (Right of

Regulatory Strategy for EMA PNH Regulatory Approval.

(a)

(b)

(c)

The Parties acknowledge and agree that (i) Apellis shall use Commercially Reasonable Efforts to obtain the
right for up to [**] Sobi representatives to attend and participate (as non-voting observers) at each portion of
any meeting of the JSC (as defined in the SFJ Agreement) under the SFJ Agreement that relates to the EMA
PNH Regulatory Approval and (ii) subject to agreement by SFJ, Sobi may communicate directly with SFJ
regarding the EMA PNH Regulatory Approval.

For the avoidance of doubt, prior to assignment of the EMA PNH Regulatory Approval in accordance with
Section 5.2.6 (Assignment of EMA PNH Regulatory Approval) the Parties shall, through the JDC pursuant
to Section 3.3.2(l) (Specific Responsibilities of the JDC), in good faith seek to agree to a regulatory strategy
for the EMA Drug Approval Application in a manner compatible with the obligations imposed on Apellis
under section 3.5(b) of the SFJ Agreement. If the Parties are unable to agree such regulatory strategy in good
faith,  the  matter  will  be  subject  to  the  decision-making  provisions  of  Section  3.7  (Decisions  of  the
Committees).  

All negotiations pursuant to this Section 5.2.5 (Regulatory Strategy for EMA PNH Regulatory Approval) are
confidential and will be treated as compromise and settlement negotiations for purposes of applicable rules
of evidence.

5.2.6

Assignment  of  EMA  PNH  Regulatory  Approval.  Notwithstanding  anything  to  the  contrary  in  Section  5.2.5
(Regulatory Strategy for EMA PNH Regulatory Approval), promptly, and in no event later than [**], following receipt
of Regulatory Approval from the EMA for a Product in PNH or such other reasonable time after [**] as requested by
Sobi, Apellis shall, at Apellis’ cost, submit to the EMA a request for transfer of the EMA PNH Regulatory Approval to
Sobi, which transfer will assign to Sobi all of Apellis’ and its Affiliates’ rights, title, and interests in and to such EMA
PNH Regulatory Approval, as well as the Regulatory Approval from the EMA for such Product in PNH (along with any
associated orphan drug designation and pediatric investigation plan). Apellis shall execute and deliver, or will cause to
be executed and delivered, to Sobi or any applicable Regulatory Authority such endorsements, assignments, and other
documents as are necessary to assign, convey, transfer, and deliver, as applicable, to Sobi such Regulatory Approval and
Drug Approval Application. Upon approval of such transfer by the EMA,

61

 
 
 
 
 
 
 
 
 
Sobi shall be the Regulatory/Reimbursement Responsible Party with respect to such Regulatory Approval.  Sobi  shall
provide Apellis with all necessary documentation required for the request to transfer no later than [**] after receipt of
Regulatory Approval from the EMA for the Product in PNH. Any failure by Sobi to provide such documentation on
such  timeline  shall  not  be  a  breach  of  this  Agreement  by  Sobi,  but  shall  relieve  Apellis  of  its  obligations  under  this
Section 5.2.6  (Assignment  of  EMA  PNH  Regulatory  Approval)  to  the  extent  and  for  the  duration  of  such  failure.  If
Apellis assigns the EMA PNH Regulatory Approval to Sobi prior to receipt of Regulatory Approval from the EMA for
the applicable Product in PNH:

(a)

(b)

(c)

(d)

(e)

Sobi  shall  use  Commercially  Reasonably  Efforts  to  seek  Regulatory  Approval  from  the  EMA  for  such
Product in PNH in accordance with Section 4.3.4 (Development Diligence Obligations); provided that Sobi
shall use no less efforts than those required by Apellis under section 3.5(b) of the SFJ Agreement;

the  Parties,  acting  via  the  JDC  pursuant  to  Section  3.3.2(l)  (Specific  Responsibilities  of  the  JDC),  shall
discuss  any  material  decisions  or  actions  with  respect  to  the  EMA  Drug  Approval  Application  for  such
Product in PNH and Sobi shall consider in good faith any reasonable comments of Apellis in relation thereto;

Apellis  shall  perform  or  procure  the  performance  of  all  actions  reasonably  requested  by  Sobi  and  deemed
necessary by Sobi in connection with the EMA Drug Approval Application for such Product in PNH and the
agreed regulatory strategy, if any;

Sobi shall have the right (and Apellis shall procure the exercise of such right) to request SFJ approval of any
proposed changes to the regulatory strategy for such EMA PNH Regulatory Approval following assignment
to Sobi;

notwithstanding  anything  to  the  contrary  in  Section  12.2  (Indemnification  by  Sobi)  and  subject  to  Section
5.2.6(h) (Assignment of EMA PNH Regulatory Approval), Section 12.3 (Indemnification Procedures), and
Section 12.4 (Limitation of Liability), Sobi hereby agrees to indemnify, defend, and hold Apellis harmless
from  and  against  any  and  all  Losses  arising  in  connection  with  any  and  all  claims  by  SFJ  to  the  extent
resulting  from  any  breach  by  Sobi  of  any  of  Section  5.2.6(a)  (Assignment  of  EMA  PNH  Regulatory
Approval), provided, however, that, (i) to the extent Sobi is implementing a regulatory strategy approved by
Apellis,  Sobi  shall  only  be  liable  to  the  extent  caused  by  Sobi’s  failure  to  use  Commercially  Reasonable
Efforts  (or,  if  greater,  those  required  by  Apellis  under  section  3.5(b)  of  the  SFJ  Agreement)  to  implement
such regulatory strategy and (ii) if Sobi is required to indemnify Apellis in respect of any penalty payments
by  Apellis  to  SFJ  under  the  SFJ  Agreement,  and  Apellis  subsequently  receives  or  has  a  right  to  receive  a
credit,  reduction,  refund,  or  set-off  in  respect  of  such  penalty  payments  against  any  remaining  payment
obligations of Apellis under that Agreement, Apellis shall, at Sobi’s option, either credit against payments
due by Sobi under Article 9 (Payments) or refund Sobi the full amount of such credit, reduction, refund, or
set-off within [**] of receipt by Apellis of such credit, reduction, refund or set-off;

(f)

Apellis shall notify Sobi promptly (but in any case within [**] of the earlier of (i) the date of Apellis’ or its
Affiliate’s receipt of any communication, notice, or other

62

 
 
 
 
 
 
 
 
 
correspondence  from  or  on  behalf  SFJ  alleging  that  Apellis  or  its  Affiliate  is  in  breach  of  its  obligations
under section 3.5(b) of the SFJ agreement or (ii) the date Apellis forms a belief that it is reasonably likely
that  Apellis  will  seek  indemnity  from  Sobi  pursuant  to  Section  5.2.6(e)  (Assignment  of  EMA  PNH
Regulatory  Approval))  of  any  alleged  dispute,  claim,  or  controversy  in  relation  to  which  Sobi  might  be
expected  to  indemnify  Apellis  pursuant  to  Section  5.2.6(e)  (Assignment  of  EMA  PNH  Regulatory
Approval);

(g)

(h)

notwithstanding anything to the contrary in Section 12.1 (Indemnification by Apellis) and subject to Section
12.3  (Indemnification  Procedures)  and  Section  12.4  (Limitation  of  Liability),  Apellis  hereby  agrees  to
indemnify, defend, and hold Sobi, its Affiliates, and their respective directors, officers, and employees, and
all of their respective successors, heirs, and assigns, harmless from and against any and all Losses arising in
connection with any and all claims by SFJ to the extent (i) resulting from Apellis’ failure to comply with its
obligations  under  the  SFJ  Agreement  prior  to  assignment  of  the  EMA  PNH  Regulatory  Approval  in
accordance  with  Section  5.2.6  (Assignment  of  EMA  PNH  Regulatory  Approval)  (including  particularly
section 3.5(b) of the SFJ Agreement) prior to transfer of the EMA PNH Regulatory Approval) or (ii) caused
by Apellis’ act or omission; and

notwithstanding anything to the contrary in this Agreement, the Parties agree that Sobi will have no liability
to  Apellis  in  connection  with  the  Drug  Approval  Application  for  such  Product  in  PNH,  whether  under
Section 5.2.6(e) (Assignment of EMA PNH Regulatory Approval), Section 12.2 (Indemnification by Sobi) or
otherwise to the extent resulting from any act or omission of Apellis or its Affiliates.

5.2.7

5.2.8

Cost of Regulatory Activities.  Each Party will solely bear all costs and expenses incurred by such Party in connection
with  the  preparation,  filing,  and  maintenance  of  Regulatory  Submissions,  Reimbursement  Submissions,  Regulatory
Approvals, and Reimbursement Approvals with respect to any Product, including any filing fees; except that Sobi shall
reimburse Apellis for all reasonable Out-Of-Pocket costs and expenses mutually agreed in advance in good faith and
incurred by Apellis in connection with the preparation, filing, and maintenance of the EMA PNH Regulatory Approval
which,  for  the  avoidance  of  doubt,  shall  not  include  any  costs  and  expenses  associated  with  any  post-approval
Development activities required in connection with such Regulatory Approval.

SFJ Participation.  Notwithstanding  anything  to  the  contrary  in  this  Agreement,  Sobi  acknowledges  and  agrees  that,
pursuant to the terms of the SFJ Agreement, the CEO or the CMO of SFJ shall be entitled to participate on a silent basis
in all meetings with the EMA during the Term (as defined in the SFJ Agreement) and, to the extent practicable, Sobi
shall give SFJ the opportunity to review pre-meeting briefing materials. Sobi shall ensure that Apellis can provide the
JSC (as defined in the SFJ Agreement) and SFJ with copies of the minutes of all such meetings within [**] (as defined
in the SFJ Agreement) after Sobi receives the final minutes from the applicable Regulatory Authority (as defined in the
SFJ Agreement).

5.3

Right of Reference

.    Subject  to  the  rules  of  the  relevant  Regulatory  Authority  and  the  terms  of  this  Agreement,  including  Section  4.4.4(b)(ii)
(Unilateral Development Data), each Party hereby grants to the other Party a “Right of Reference,” as that term is defined in 21 C.F.R. §
314.3(b) (or any successor rule or analogous Applicable Law recognized outside of the U.S.), to, and a right to copy,

63

 
 
 
 
 
 
 
access,  and  otherwise  use,  all  information  and  data  relating  to  any  Compound  or  Product  in  any  Regulatory  Submission  or  Regulatory
Approval Controlled  by  such  Party,  for  such  other  Party’s  or  its  Affiliates’  use  in  the  Exploitation  of  (including  the  filing,  issuance,  and
maintenance of Regulatory Approvals for) the Products in accordance with this Agreement.  If requested by either Party, the other Party shall
provide a signed statement to this effect in accordance with 21 C.F.R. § 314.50(g)(3) (or any successor rule or analogous Applicable Law
outside  of  the  U.S.)  to  give  effect  to  the  intent  of  this  Section  5.3  (Right  of  Reference).  For  clarity,  nothing  in  this  Section  5.3  (Right  of
Reference) entitles a Party to use the Unilateral Development Data of the other Party unless such party has exercised its buy-in rights under
Section 4.4.4(b)(iii) (Buy-In).

5.4

Adverse Event Reporting

.

5.4.1

5.4.2

SDEA; Responsibilities. No later than [**] after the Effective Date, the Parties shall discuss and execute a Safety Data
Exchange Agreement (the “SDEA”), which will set forth the responsibilities of each Party with respect to clinical safety
and pharmacovigilance matters relating to each Product and Non-Systemic Ophthalmology Product. The Parties shall
update the SDEA from time to time as needed to properly reflect the status of the marketing and sale of each Product
and  the  relevant  regulations  in  each  country.  In  the  SDEA,  the  Parties  shall  define  how  clinical  safety  and
pharmacovigilance will be managed by both Parties, how the safety database for the Products will be set up and how
safety  information  will  be  exchanged,  and  in  particular  shall:  (a)  set  forth  how  cases  will  be  processed  in  the  global
safety database; (b) provide for submitting expedited reports in agreed format to health authorities, in accordance with
the requirements of Regulatory Authorities; (c) include provisions regarding producing outputs (tables, line listings) for
aggregate reports such as periodic safety update reports and development safety update reports; (d) include provisions
regarding  evaluation  of  safety  and  benefit-risk  (e.g.,  results  should  be  discussed  in  the  JEC  or  a  subcommittee,  as
specified in the SDEA); (e) include provisions regarding performing ongoing safety signal detection and assessment;
and (f) include provisions governing safety statements in aggregate reports, in each case ((a)-(f)) in a manner consistent
across countries to the extent reasonably practicable. The Parties, through the JEC or any subcommittee established by
the  JEC  for  the  purpose,  shall,  as  set  forth  in  more  detail  in  the  SDEA,  jointly  establish  and  maintain  all  necessary
pharmacovigilance  activities  for  each  Product  in  compliance  with  all  Applicable  Laws  and  requirements  of  all
applicable  Regulatory  Authorities.  During  the  Term,  each  Party  shall  notify  the  other  Party  regarding  all  Serious
Adverse Events arising in any Clinical Trials of any Product or Non-Systemic Ophthalmology Product, all adverse drug
reactions (i.e. Adverse Events that are related to a Product or Non-Systemic Ophthalmology Product), and all special
case  scenarios,  as  outlined  in  the  EMA’s  Guideline  on  Good  Pharmacovigilance  Practices,  Module  VI,  as  individual
cases within the timelines specified in the SDEA. Further adverse events may be exchanged as aggregated reports or
data sets, as specified in the SDEA. Additionally, any other safety-relevant information (beyond adverse events) shall be
exchanged as outlined in the SDEA.

Regulatory/Reimbursement  Responsible  Party  Responsibilities.    The  Regulatory/Reimbursement  Responsible
Party’s responsibilities for each Product in a country will include: (a) receiving and collecting all applicable Adverse
Events  and  adverse  drug

Regulatory/Reimbursement  Responsible  Party’s  standard  operating  procedures,  (b)  obtaining  follow-up  information
related to any Adverse Events or adverse drug reactions for such Product in such country that is initially made to or
received by such Regulatory/Reimbursement Responsible Party and forwarding the same to the non-

reactions,  as  defined 

in  accordance  with 

the  SDEA, 

64

 
 
 
 
Regulatory/Reimbursement  Responsible  Party  as  established  in  the  SDEA;  (c)  making  regulatory  and  safety  contacts
with  the  Regulatory  Authorities  and  other  Governmental  Authorities  in  such  country  as  the  holder  of  the  relevant
Regulatory  Approvals,  INDs,  or  CTAs  (as  applicable)  for  such  Product;  (d)  submitting  case  reports  that  qualify  for
expedited  reporting  to  the  Regulatory  Authorities  in  such  country  as  required  by  Applicable  Law;  (e)
submitting  aggregate reports (e.g., post-marketing periodic safety update reports) to the Regulatory Authorities in such
country  as  required  by  Applicable  Law;  and  (f)  promptly  communicating  to  the  non-Regulatory/Reimbursement
Responsible  Party  any  new  safety  signal  with  respect  to  any  Product.  The  Regulatory/Reimbursement  Responsible
Party’s responsibilities for each Product will also include: (x) establishing and maintaining risk management plans and
measures  for  the  applicable  countries,  except  to  the  extent  the  Parties  agree  that  the  non-Regulatory/Reimbursement
Responsible Party will execute such plans; and (y) establishing applicable country-specific named pharmacovigilance
contacts as required by Applicable Law. Details regarding the responsibilities outlined above shall be specified in more
detail, on a country-by-country level, in the SDEA.  

5.4.3

Audit Rights and Inspection Reports.  Each Party will have the right, upon reasonable (and at least [**]) prior written
notice,  to  periodically  audit  the  other  Party’s  relevant  Product-related  pharmacovigilance  activities  to  monitor
compliance  with  such  other  Party’s  obligations  as  set  forth  in  this  Section  5.4  (Adverse  Event  Reporting)  and  the
SDEA.  Each Party shall, within a reasonable time, reply to the other Party’s request for such an audit.  Each such audit
will be reasonable in scope and take place during normal business hours.  Neither Party may request an audit more than
[**], except where there is a reasonable basis for such Party to suspect that the other Party has failed or is failing to
comply  with  its  obligations  under  this  Section  5.4  (Adverse  Event  Reporting)  or  the  SDEA.  The  auditing  Party  shall
share any concerning findings related to the Compound or the Products resulting from any pharmacovigilance audit in a
reasonably detailed inspection report, and the Parties shall agree in good faith on the corrective and preventative actions
to be taken by the Parties to address such findings, and the Party(ies) responsible for such actions shall take such actions
promptly after they are agreed to.

5.4.4

Allocation  of  Clinical  Safety  and  Pharmacovigilance  Responsibilities.  Each  Party  shall  notify  the  other  Party  in
writing promptly following the Effective Date regarding the names and contact information of such Party’s leaders for
clinical safety and pharmacovigilance activities, including such Party’s European Union Qualified Person Responsible
for  Pharmacovigilance.  Each  Party  shall  also  inform  the  other  Party  about  outsourcing  major  components  of  such
Party’s clinical safety and pharmacovigilance responsibilities covered by the SDEA.

5.5

Recall, Withdrawal, or Field Alert of the Products

.

5.5.1

Notification  and  Determination.  If  any  Governmental  Authority  (a)  threatens  in  writing,  or  initiates,  any  action  to
remove  any  Product  or  Non-Systemic  Ophthalmology  Product  from  the  market  (in  whole  or  in  part)  or  (b)  provides
written notice regarding a potential safety or quality issue with respect to any Product or Non-Systemic Ophthalmology
Product,  then,  in  each  case  ((a)  or  (b)),  the  Party  receiving  notice  thereof  will  notify  the  other  Party  of  such
communication  promptly,  but  in  no  event  later  than  [**]  after  receipt  thereof.  Notwithstanding  the  foregoing,  in  all
cases Sobi shall determine whether to initiate any recall, withdrawal, or field alert of any Product in any country in the
Sobi Territory and Apellis shall determine whether to initiate any recall, withdrawal, or field alert of any

65

 
 
 
 
 
 
Product in the Apellis Territory or any Non-Systemic Ophthalmology Product anywhere in the world, including, in each
case, the scope of such recall or withdrawal (e.g., a full or partial recall, or a temporary or permanent recall) or field
alert. Before either Party initiates a recall, withdrawal, or field alert relating to a Product, the Party initiating such recall,
withdrawal, or field alert shall notify the other Party within [**] of such decision and the Parties shall use reasonable
efforts  to  promptly  discuss  in  good  faith  the  reasons  therefor,  but  such  discussions  will  not  delay  any  action  that  the
Party initiating such recall reasonably believes should be taken in relation to any actual or potential recall, withdrawal,
or field alert.  In the event of any such recall, withdrawal, or field alert relating to a Product, the Party initiating such
recall, withdrawal, or field alert shall determine the necessary actions to be taken and will implement such actions.

5.5.2

Cost Allocation.  Except as set forth in the Supply Agreement, (a) the Parties shall share as Shared Development Costs,
all  reasonable  costs  and  expenses  incurred  by  a  Party  in  connection  with  implementing  a  recall,  withdrawal,  or  field
alert  with  respect  to  any  Product  then  being  Developed  under  the  Global  Development  Plan,  and  (b)  each  Party  will
solely bear all costs and expenses incurred by such Party in connection with implementing a recall, withdrawal or field
alert  in  each  case  with  respect  to  any  Product  being  Commercialized  by  such  Party,  provided that  to  the  extent  such
recall,  withdrawal,  or  field  alert  is  required  as  a  result  of  a  failure  by  or  on  behalf  of  Apellis  to  Manufacture  in
accordance  with  applicable  Specifications  and  the  Supply  Agreement,  but  not  to  the  extent  any  such  recall  is
attributable to the breach or negligence of Sobi, its Affiliates, or Sublicensees, Apellis will reimburse Sobi for all costs
and expenses incurred by Sobi in connection with implementing such recall, withdrawal, or field alert.

6.1

Overview

ARTICLE 6

COMMERCIALIZATION

. Subject to the terms and conditions of this Agreement, (a) Apellis shall Commercialize Products in the Apellis Territory and (b)
Sobi shall Commercialize Products in the Sobi Territory. Neither Party may Commercialize any Product in a manner inconsistent with this
Agreement. Each Party shall, where commercially reasonable in the relevant country, Commercialize the Products in each country in such
Party’s territory in a manner that is consistent with the then-current Global Branding Strategy (including as to Product Trademarks), if any. If
a Party determines that it is not commercially reasonable in a given country to Commercialize a Product in a manner that is consistent with
the then-current Global Branding Strategy (if any), such Party shall so notify the JCC and give the other Party opportunity to comment on the
positioning,  messaging,  branding,  packaging,  and  labeling  (including  Product  Trademarks)  intended  to  be  used  in  such  country  and  shall,
notwithstanding the foregoing, use Commercially Reasonable Efforts to comply with the Global Branding Strategy and reasonable comments
from the other Party.

6.2

Commercialization Diligence Obligations

. Sobi shall use Commercially Reasonable Efforts to Commercialize a Product in each of the Initial Indications in (a) at least [**]
of the Major European Countries and (b) each of Canada, Japan, Brazil, and China. Apellis acknowledges that, without prejudice to Section
6.5  (Expansion  and  Launch  in  the  Sobi  Territory),  when  determining  the  timing  and  order  of  Commercial  launch  of  a  given  Product  and
Initial Indication in each Major Market, Sobi may reasonably take into account reference pricing strategy. Apellis acknowledges that Sobi
shall not be in breach of its Commercialization diligence obligations under this Agreement to the extent caused by the acts or omissions of
Apellis or its Affiliates.

6.3

Global Branding Strategy and Information

.

66

 
 
 
 
6.3.1

6.3.2

Global Branding Strategy. At least [**] prior to the anticipated First Commercial Sale of the first Product in the later
of the Sobi Territory or the Apellis Territory, the JCC shall discuss in good faith and use reasonable efforts to agree and
submit  to  the  JEC  to  review,  discuss,  and  determine  whether  to  approve,  an  initial  Global  Branding  Strategy.  If  the
Parties  cannot  agree  upon  a  Global  Branding  Strategy,  the  Parties  shall  instead  reasonably  coordinate  on  Product
branding matters.

Updating the Global Branding Strategy. At least [**] during the Term (or more frequently as may be required or as
may be reasonably requested by either Party), the JCC shall review and, if unanimously agreed by the JCC, update any
prior  approved  Global  Branding  Strategy  based  on  currently  available  information  and  data.  The  JCC  shall  review,
discuss,  and  determine  whether  to  approve  any  such  update  to  the  Global  Branding  Strategy,  and  shall  submit  to  the
JEC  to  review,  discuss,  and  determine  whether  to  approve  each  such  update  to  the  Global  Branding  Strategy  that  is
material.  Each  such  update  to  the  Global  Branding  Strategy  will  become  effective  and  will  supersede  the  previous
Global Branding Strategy upon approval thereof by the JCC, and, if applicable, JEC. If such update is not unanimously
approved by the JCC and the JEC, then the prior approved Global Branding Strategy (if any) shall remain in place.

6.4

Pricing

.  Each Party will be free, in its sole discretion, to determine the price, if any, that it charges Third Parties for each Product in each
country in which such Party is Commercializing such Product, but, to the extent permitted by Applicable Law in the relevant country, each
Party shall endeavor to consider each Product’s value in setting the price of such Product.

6.5

Expansion and Launch in the Sobi Territory

.    Without  limiting  its  obligations  under  Section  6.2  (Commercialization  Diligence  Obligations),  Sobi  will  be  free,  in  its  sole
discretion  determine  geographical  expansion  and  launch  sequences  for  each  Product  in  the  Sobi  Territory.  Sobi  shall  give  the  JCC  a
reasonable opportunity to comment on Sobi’s proposed expansion and launch sequences for each Product in the Sobi Territory in advance of
Sobi’s final determination of the same.

6.6

Commercialization Costs

respects with all Applicable Laws in Commercializing the Products.  Each Party shall promptly inform the JCC of any material investigation
or adverse action taken by any Governmental Authority with respect to the Commercialization of any Product of which such Party becomes
aware.

6.8

Promotional Materials

.    Each  Party  shall  submit  copies  of  initial  versions  of,  and  (in  respect  of  the  Major  Markets  and  Apellis  Territory  only)  any
material updates to, the Promotional Materials that it uses to Commercialize Products in its territory to the JCC for discussion purposes only.
Each  Party  shall  ensure  that  all  Promotional  Materials  used  by  or  on  behalf  of  such  Party  for  any  Product  are  compliant  with  Applicable
Laws and materially consistent with the Global Branding Strategy, if any.

6.9

Product Trademarks

.  Subject to Section 6.1 (Overview), each Party shall determine the trademarks used in connection with the Exploitation of the
Products in its respective territory following reasonable consultation with the other Party (excluding any house marks or composite marks
that include a house mark, the “Product Trademarks”).

67

 
 
 
 
6.9.1

Ownership;  Use.   Apellis  will  own  all  Product  Trademarks  in  the  Apellis  Territory,  and  Sobi  will  own  all  Product
Trademarks in the Sobi Territory. Each Party agrees that it and its Affiliates shall not use, register, or attempt to register
any Product Trademark so resembling any existing trademark of the other Party in the applicable jurisdiction(s) as to be
likely to cause confusion or deception, and each Party agrees that such Party and its Affiliates shall not use, register, or
attempt  to  register  in  the  other  Party’s  territory  any  trademark  so  resembling  the  Product  Trademarks  in  such  other
Party’s territory as to be likely to cause confusion or deception.

6.9.2

Responsibility for Product Trademarks.

(a)

(b)

(c)

Apellis  shall  be  responsible  for  (i)  registering,  prosecuting,  and  enforcing  the  Product  Trademarks  in  the
Apellis Territory, (ii) preparing any guidelines applicable to the use of the Product Trademarks in the Apellis
Territory, and (iii) investigating and defending any infringement or threatened infringement relating to any
Product  Trademark  in  the  Apellis  Territory.  Apellis  will  own  and  be  responsible  for  securing  any  domain
names associated with the Product Trademarks targeted at the Apellis Territory. Subject to Section 6.9.2(c)
(Responsibility  for  Product  Trademarks),  neither  Sobi  nor  any  of  its  Affiliates  shall  obtain  or  hold  any
domain  name  associated  with  the  Product  Trademarks  targeted  at  the  Apellis  Territory  in  its  own
name.   Apellis  shall  not  use  nor  permit  the  use  by  its  Affiliates  or  licensees  of  the  Product  Trademarks  in
connection with any Non-Systemic Ophthalmology Product anywhere in the world. Apellis shall not use any
Product Trademark as part of any Drug Approval Application filed with the EMA for PNH without Sobi’s
prior written consent.

Sobi shall be responsible for (i) registering, prosecuting, and enforcing the Product Trademarks in the Sobi
Territory, (ii) preparing any guidelines applicable to the use of the Product Trademarks in the Sobi Territory,
and  (iii)  investigating  and  defending  any  infringement  or  threatened  infringement  relating  to  any  Product
Trademark  in  the  Sobi  Territory.    Sobi  will  own  and  be  responsible  for  securing  any  domain  names
associated  with  the  Product  Trademarks  targeted  at  the  Sobi  Territory.  Subject  to  Section  6.9.2(c)
(Responsibility  for  Product  Trademarks),  neither  Apellis  nor  any  of  its  Affiliates  shall  obtain  or  hold  any
domain names associated with the Product Trademarks targeted at the Sobi Territory in its own name.

The Parties shall, through the JEC, discuss and determine ownership and content of the landing pages for any
domain  names  associated  with  any  Product  that  are  targeted  at  both  the  Sobi  Territory  and  the  Apellis
Territory  (including  “.com”  and  “.net”  domains).  Each  such  landing  page  shall  utilize  then-current
technology  as  necessary  to  direct  those  Persons  located  in  a  particular  country  to  the  appropriate  website
specified by Sobi for Persons located in the Sobi Territory and by Apellis for Persons located in the Apellis
Territory. For clarity, Apellis shall be responsible for the web presence for Products in the Apellis Territory
and  Sobi  shall  be  responsible  for  the  web  presence  for  Products  in  the  Sobi  Territory;  and  the  responsible
Party shall ensure that such web presence (including all associated content) shall comply with all Applicable
Law and regulatory requirements.

6.9.3

Respect of Product Trademarks.  Neither Party shall, and each Party shall ensure that its Affiliates do not: (a) attack,
challenge, oppose, petition to cancel, or initiate legal action or

68

 
 
 
 
 
 
 
 
6.9.4

proceedings in connection with any Product Trademark in any country in the other Party’s territory during the Term, or
challenge the registration of any Product Trademark in any country in the other Party’s territory during the Term; (b)
file,  register,  or  maintain  any  registrations  for  any  trademarks  or  trade  names  (including  with  respect  to  any  Non-
Systemic  Ophthalmology  Product)  in  any  country  in  the  other  Party’s  territory  that  are  confusingly  similar  to  any
Product  Trademark  in  such  country,  without  the  express  prior  written  consent  of  the  other  Party;  or  (c)  authorize  or
assist any Third Party to do the foregoing.

Apellis Name.  To  the  extent  permitted  by  Applicable  Law  and  the  relevant  Regulatory  Authority(ies),  and  provided
such inclusion is not reasonably likely to cause confusion regarding the holder of the relevant Regulatory Approval or
the  source  of  the  Product,  the  packaging  for  each  Product  sold  in  the  Sobi  Territory  Manufactured  by  Apellis  shall
identify Apellis as the manufacturer of the Product and shall include the Apellis company trademark,  provided that, to
the  extent  permitted  by  Applicable  Law,  the  Apellis  company  name  and  trademark  will  appear  on  the  outside  of  the
packaging, but will not be located on the front side of the packaging and will appear smaller and less prominent than the
Sobi  name  and  company  trademark.  If  Apellis  ceases  to  Manufacture  the  relevant  Product,  other  than  as  a  result  of
Apellis’ breach of this Agreement, the Parties will discuss in good faith whether and how Apellis’ name and company
trademark  may  continue  to  appear  on  Product  packaging  in  the  Sobi  Territory  to  the  extent  permitted  by  Applicable
Law and the relevant Regulatory Authority(ies). Apellis hereby grants to Sobi a non-exclusive, royalty-free license to
use  the  Apellis  name  and  company  trademark  for  such  purpose.  Sobi  shall  provide  Apellis  with  a  mock-up  of  its
proposed  packaging  in  advance  of  the  use  of  such  packaging,  following  which  Apellis  will  have  [**]  to  provide  its
reasonable comments on such proposed packaging which Sobi shall consider in good faith. Sobi will use Commercially
Reasonable Efforts to maintain the quality of the Product on which the Apellis trademarks are presented in a manner
consistent with (i) Applicable Law, (ii) the quality standards set out in Schedule 6.9.4 (Apellis Trademark Standards),
and  (iii)  any  other  reasonable  quality  standards  as  may  be  mutually  agreed  from  time  to  time  by  the  Parties,  acting
reasonably and in good faith, provided that failure to do so will not be a breach of this Agreement and Apellis’ sole and
exclusive remedy will be the right to require Sobi to cease to Manufacture or have Manufactured Products bearing the
Apellis trademark and Sobi shall use Commercially Reasonable Efforts to cease such activities as soon as reasonably
practicable (taking into account Sobi and its Affiliates’ and Sublicensee’s ability to continue to supply the markets in
the Sobi Territory with sufficient Product to meet demand and avoid supply interruption, the requirements of Applicable
Law  and  any  Regulatory  Authority),  provided  that  Sobi  shall  continue  to  have  the  right  to  Manufacture  and
Commercialize  Product  bearing  the  Apellis  name  and  company  trademark  provided  it  complies  with  the  foregoing
obligation  during  the  aforementioned  ramp-down  period.  From  and  after  any  Change  of  Control  of  Apellis,  Sobi’s
obligations  to  display  the  Apellis  name  and  trademark  on  the  packaging  of  Products  in  the  Sobi  Territory  under  this
Section 6.9.4 (Apellis Name) shall cease and Sobi’s remaining obligations under this Section 6.9.4 (Apellis Name) shall
cease if and when, at Sobi’s sole discretion, Sobi ceases including the Apellis name and trademark on the packaging of
Products in the Sobi Territory.

8.1

Sobi Right to Manufacture

Drug Substance.  

ARTICLE 8
MANUFACTURING

8.1.1

8.1.2

Drug Substance. Notwithstanding Sections 8.5 (Supply of Compound and Product for Development Activities) and 8.6
(Supply  Agreement),  Apellis  acknowledges  and  agrees  that  Sobi  shall  have  the  right  to  Manufacture,  through  any  of
Apellis’  contract  manufacturing  organizations  (or  any  Third  Party  supplier  to  Apellis’  contract  manufacturing
organizations of materials or intermediates) or any contract manufacturing organization or supplier identified by Sobi
and reasonably acceptable to Apellis, the Compound in formulated bulk drug substance form (“Drug Substance”) (a)
upon a Change of Control of Apellis or (b) upon a Failure to Supply under the Supply Agreement.

Local Manufacturing. If Sobi notifies the JMSC that, under Applicable Law or the requirements of any Regulatory
Authority or any other Governmental Authority, local Manufacturing by or on behalf of Sobi is required in a particular
country or region in the Sobi Territory of the Drug Substance of any Product sold in such country or region, the JMSC
shall  determine  whether  and  on  what  conditions  Sobi  shall,  itself  or  through  an  Affiliate  or  Third  Party  reasonably
acceptable  to  Apellis,  Manufacture  such  Drug  Substance  in  such  country  or  region,  pursuant  to  Section  3.6.2(e)
(Specific Responsibilities of the JMSC).

(a)

(b)

If the JMSC cannot agree on a process for Manufacturing Drug Substance in a given country or region in the
Sobi Territory where local Manufacturing of such Drug Substance is required in order for Sobi to Develop or
Commercialize any Product in such country or region, then (i) such disagreement shall be referred to the JEC
for resolution in accordance with Section 3.7.2 (Escalation to JEC) and (ii) Sobi may not Manufacture Drug
Substance in such country or region, but Sobi’s diligence obligations with respect to such Product in such
country  or  region  shall  cease  unless  and  until  the  JEC  unanimously  agrees  to  a  process  for  such  local
Manufacturing.

For purposes of this Section 8.1.2 (Local Manufacturing), (i) Apellis shall not unreasonably refuse to agree
to any contract manufacturing organization or any plan to address any requirement under Applicable Law or
the requirements of any Regulatory Authority or any other Governmental Authority for local Manufacturing,
(ii)  Apellis  acknowledges  that  China  is  an  important  market  for  Products  for  Sobi,  and  (iii)  Sobi
acknowledges (A) the importance of Apellis’ contractual obligations under the Apellis Supply Agreements
and  (B)  the  sensitivity  of  confidential  Manufacturing  Know-How  and  other  Know-How  of  Apellis  and  its
Third Party manufacturing partners.

8.2

Sobi Right to Manufacture Drug Product

.  The Parties shall collaborate in good faith to qualify and validate a contract manufacturing organization reasonably acceptable to
both Parties to serve as a second source of supply for final dosage form (but not in Finished Form) of the Products (“Drug Product”) for
Apellis and a primary source of supply for Drug Product for Sobi, provided

72

 
 
 
 
 
 
however  that,  if  the  Parties  cannot  agree  on  such  contract  manufacturing  organization  Sobi  may  identify  a  contract  manufacturing
organization  reasonably  acceptable  to  Apellis  (and  Apellis  may  not  unreasonably  withhold  its  consent  to  such  contract  manufacturing
organization) and with whom Sobi shall be the contracting party, to be qualified and validated as a primary source of supply for Drug Product
for Sobi (in either case, such contract manufacturing organization the “Second Source”). Subject to the terms of the Supply Agreement, Sobi
may obtain [**] percent ([**]%) of its requirements of Drug Product from such Second Source at any time during the Term, but Sobi will
coordinate with Apellis via the JMSC to minimize adverse effects upon Apellis.

8.3

Manufacturing Technical Transfer

.  

8.3.1

Manufacturing  Know-How.  Without  limiting  either  Party’s  obligations  under  Section  2.4  (Technology,  Data,  and
Regulatory Transfer) or Section 8.1.2 (Local Manufacturing), within a reasonable time period following the engagement
by Sobi of an applicable contract manufacturing organization or supplier reasonably acceptable to Apellis pursuant to
Section 8.1 (Sobi Right to Manufacture Drug Substance) (with respect to Drug Substance) or Sobi’s engagement of the
Second Source (with respect to Drug Products), as applicable, Apellis shall provide (or cause its relevant Affiliates or
subcontractors of Drug Substance or Drug Product, as applicable, to provide) such contract manufacturing organization,
supplier, or Second Source (as applicable) with all Apellis Know-How necessary to Manufacture the Drug Substance or
the  Drug  Product,  as  applicable,  (the  “Manufacturing  Know-How”)  that  has  not  previously  been  transferred  in
accordance with Section 2.4 (Technology, Data, and Regulatory Transfer) or Section 8.1.2 (Local Manufacturing), to be
held in confidence by such contract manufacturing organization, supplier, or Second Source (as applicable) until such
time  (if  any)  that  Sobi  obtains  the  right  to  Manufacture  Drug  Substance  or  Drug  Product  (as  applicable)  pursuant  to
Section 8.1 (Sobi Right to Manufacture Drug Substance) or Section 8.2 (Sobi Right to Manufacture Drug Product) (as
applicable).

8.3.2

Manufacturer Know-How.

(a)

To  the  extent  necessary  to  obtain  and  maintain  Regulatory  Approvals  for  Products  in  each  country  in  the
Sobi Territory and to Manufacture Drug Substance or Drug Product (as applicable) pursuant to Section 8.1
(Sobi Right to Manufacture Drug Substance) or Section 8.2 (Sobi Right to Manufacture Drug Product) (as
applicable), Apellis will exercise Commercially Reasonable Efforts to either (i) obtain for Sobi from [**] the
right  to  use  and  disclose  or  reference  (itself  or  through  [**])  any  Know-How,  Intellectual  Property,
Regulatory  Data,  or  drug  master  file  controlled  by  [**]  that  is  not  Assigned  Manufacturer  IP  or  Licensed
Manufacturer  IP  or  (ii)  subject  to  Section  8.3.2(b)  (Manufacturer  Know-How),  promptly  establish  an
alternate supplier to provide any such Know-How (an “Alternate Supplier”). If (A) in order to enable Sobi
to  obtain  and  maintain  Regulatory  Approval  for  a  Product  in  a  country  in  the  Sobi  Territory,  Apellis  is
required to establish an Alternate Supplier and (B) such establishment of an Alternate Supplier delays Sobi’s
receipt of Regulatory Approval for such Product in such country, then (if it has not already been paid) Sobi
shall no longer be required to pay Apellis the [**] Dollar ($[**]) Development Milestone Payment for the
[**].

(b)

If Apellis is required to establish an Alternate Supplier pursuant to Section 8.3.2(a)(ii) (Manufacturer Know-
How), Apellis shall:

73

 
 
 
 
 
 
(i)

(ii)

(iii)

use Commercially Reasonable Efforts to establish an Alternate Supplier that is fully and properly
qualified  and  validated  and  in  a  position  to  Manufacture  Drug  Substance  or  Drug  Product  (as
applicable)  in  accordance  with  Sobi’s  then-current  Development  timeline  and  the  Global
Development Plan;

reasonably  consult  with  Sobi  in  any  negotiations  with  such  Alternate  Supplier  and  consider  in
good faith any reasonable comments of Sobi on the proposed agreement(s) with such Alternate
Supplier; and

use  Commercially  Reasonable  Efforts  to  arrange  with  such  Alternate  Supplier  that  any  Know-
How  developed  by  such  Alternate  Supplier  that  is  necessary  to  obtain  and  maintain  Regulatory
Approvals for Products in each country in the Sobi Territory and to Manufacture Drug Substance
or Drug Product will be Controlled by Apellis.

(c)

In the event that, despite the use of Commercially Reasonable Efforts, Apellis is both unable to obtain for
Sobi the rights set forth in Section 8.3.2(a)(i) (Manufacturer Know-How) and unable to obtain a Alternate
Supplier as set forth in Section 8.3.2(a)(ii) (Manufacturer Know-How), then:

(i)

(ii)

the  Parties  will  cooperate  in  good  faith  to  resolve  the  issue,  using  Commercially  Reasonable
Efforts, as soon as reasonably practicable; and

to the extent and for so long as Sobi is unable to obtain and maintain Regulatory Approval for a
given Product in a given country due to Sobi’s inability to use or disclose applicable Know-How
controlled  by  the  Manufacturers  of  such  Product,  Sobi’s  diligence  obligations  to  obtain
Regulatory  Approval  for,  and  Commercialize,  such  Product  in  such  country  under  Section  4.3
(Development Diligence Obligations) and Section 6.2 (Commercialization Diligence Obligations)
shall cease, Apellis shall have no right to terminate this Agreement with respect to such country
pursuant to Section 14.2.2(b) (Breach by Sobi), and nothing in this Agreement (other than Article
13  (Confidentiality))  shall  restrict  Sobi  from  performing  such  activities  as  it  reasonably
determines  are  necessary  to  produce  or  recreate  the  Know-How  that  Sobi  needs  to  obtain  and
maintain  Regulatory  Approval  for  such  Product  in  such  country.  The  remedies  provided  in  this
Section 8.3.2(c)(ii) (Manufacturer Know-How) are in addition to, and not in substitution for, any
other remedies provided in this Agreement or now or hereafter existing at law or in equity.

8.4

Manufacturing and Supply Chain Plan

.    No  later  than  [**]  after  the  Parties  establish  the  JMSC,  the  JMSC  shall  prepare  and  provide  to  the  Parties  for  review  and
approval  a  reasonably  detailed  plan  for  the  Manufacture  and  supply  of  the  Compounds  and  Products  (including  any  Manufacturing
improvements)  by  or  on  behalf  of  Apellis  for  Development  and  Commercialization  purposes  for  the  following  [**]  period  (the
“Manufacturing and Supply Chain Plan”). The initial draft of such plan and all updates thereto shall provide an overview of the following
for at least the following [**] period: (a) reserved capacity (to the extent reasonable and applicable) and minimum purchase commitments for
supply of the Compounds and Products, (b) each Third Party engaged to perform each step in the Manufacturing activities and supply chain
of Apellis, including an end-to-end mapping of all such Third Parties engaged, (c) Apellis’ plans to establish alternate suppliers (to the

74

 
 
 
 
 
 
 
 
extent reasonable and applicable), (d) Apellis’ capabilities for undertaking Manufacturing lifecycle management changes with respect to any
Compound or Product, and (e) a go-to-market supply plan for Product to be supplied under the Supply Agreement. The JMSC shall review
and update, and provide to the Parties for review and approval, the updated Manufacturing and Supply Chain Plan at least [**] (unless the
Parties agree in writing to a different frequency).

8.5

Supply of Compound and Product for Development Activities.

8.5.1

Development Supply. Pursuant to the terms of the Supply Agreement once executed and, prior to execution, pursuant
to  this  Section  8.5.1  (Development  Supply),  Apellis  shall  Manufacture  and  supply  (or  ensure  the  Manufacture  and
supply  of)  quantities  of  Compound,  Product,  and  placebo  as  necessary  for  the  completion  of:  (x)  the  Global
Development Activities assigned to Apellis or Sobi in the Global Development Plan and (y) the Unilateral Development
Activities and Unilateral Combination Therapy Development Activities conducted by or on behalf of Apellis or Sobi.  

8.5.2

Shelf Life and Compliance. Apellis shall ensure that, at the time of delivery of Compound or Product for Development
purposes in accordance with Section 8.5.1 (Development Supply) or the Supply Agreement:

(a)

(b)

the  Compound,  Product,  and  placebo,  as  applicable,  shall  have  a  remaining  shelf  life  as  is  required  to
conduct the Clinical Trial for which it is being supplied; and

the  Compound,  Product,  and  placebo,  as  applicable,  shall  have  been  Manufactured,  released,  stored,
supplied,  packaged,  and  labelled  in  compliance  with:  (i)  the  applicable  specifications;  (ii)  the  Quality
Agreement; and (iii) all Applicable Law, applicable GMP, and GCP.

8.5.3

Inspection.  If Apellis becomes aware or determines that Compound, Product, or placebo, as applicable, supplied by
Apellis to Sobi pursuant to this Section 8.5 (Supply of Compound and Product for Development Activities) is not, or
has not been Manufactured, released, stored, supplied, packaged, and labelled, in compliance with the requirements set
forth in Section 8.5.2 (Shelf Life and Compliance), then Apellis shall promptly provide written notice thereof to Sobi
and  shall  remedy  such  non-compliance  and,  without  limiting  the  foregoing,  shall  promptly  enforce  any  rights  or
obligations under Apellis’ written agreement with any contract manufacturing organization or Third Party supplier to
ensure such violations are rectified as expeditiously as possible. In the event of such notice, or if Sobi has reasonable
concerns  about  compliance  with  such  requirements,  Apellis  shall,  to  the  extent  permitted  under  its  applicable
agreements, permit (and shall cause its contract manufacturing organization or Third Party supplier to permit) Sobi or
an independent Third Party to enter the manufacturing site of such contract manufacturing organization or supplier to
inspect and verify compliance with such requirements.

8.5.4

Responsibility.  Apellis  shall  be  solely  responsible  for  obtaining  and  maintaining  (or  for  ensuring  that  its  relevant
contract manufacturers obtain and maintain) all approvals of Regulatory Authorities that are required to Manufacture,
release, store, and supply the Compound, Product, or placebo, as applicable, in compliance with Applicable Law and
GMP.

Sobi  shall  be  excused  from  any  non-performance  under  this  Agreement  to  the  extent  resulting  from  Apellis’  Failure  to  Supply

Product under this Agreement in a timely manner.

75

 
 
 
 
 
 
 
 
 
8.6

Supply Agreement

.    Without  limiting  Section  8.5  (Supply  of  Compound  and  Product  for  Development  Activities),  within  [**]  after  the  Effective
Date, the Parties shall negotiate in good faith and enter into a supply agreement that will govern the terms and conditions of the Manufacture
and supply of Drug Substance and Drug Product by Apellis to Sobi and its Affiliates for use in Development and Commercialization, along
with  a  related  quality  agreement  (the  “Supply  Agreement”).  The  Supply  Agreement  shall  be  consistent  with  this  Agreement  and  shall
contain  the  terms  set  forth  in  Schedule  8.6  (Supply  Agreement  Material  Terms),  and  otherwise  contain  terms  customary  for  supply
agreements  between  licensees  and  licensors.  Apellis  shall  supply,  and  Sobi  shall  purchase,  Drug  Substance  and  Drug  Product  in  the
quantities,  on  the  timelines,  at  the  prices,  and  otherwise  subject  to  the  terms  and  conditions,  set  forth  in  the  Supply  Agreement.  For  the
avoidance  of  doubt,  none  of  the  JMSC,  the  JDC,  the  JMC,  JCC  nor  the  JEC  shall  have  any  power  or  authority  to  amend  or  require  any
amendment  to  the  Supply  Agreement.  For  clarity,  Sobi  shall  be  excused  from  any  non-performance  under  this  Agreement  resulting  from
Apellis’ Failure to Supply Product under the Supply Agreement in a timely manner.

8.7

Packaging and Delivery

.  Sobi shall be responsible for all Finished Form packaging for Products for  clinical studies and Clinical Trials conducted by or
on behalf of Sobi and for Commercialization in each country in the Sobi Territory, except for clinical studies and Clinical Trials as to which
the  Global  Development  Plan  provides  that  Sobi  and  Apellis  shall  mutually  agree  upon  the  responsibility  for  such  Finished  Form
packaging.   Without  limiting  the  foregoing,  Sobi  shall  have  the  right,  in  its  sole  discretion,  to  co-pack  the  Product  with  an  administration
device in any country in the Sobi Territory.

8.8

Supply Shortages

.  In the event that any shortage in the quantities of materials or Compound or constraint of Apellis’ or its Affiliates’ or any Third
Party’s  Manufacturing  capacity  will  or  is  reasonably  likely  to  affect  quantities  of  Supplied  Product  (as  defined  in  Schedule  8.6  (Supply
Agreement  Material  Terms))  available  to  Sobi,  Apellis  shall  not  prioritize  supply  to  Apellis  (either  for  the  Product  or  the  Non-Systemic
Ophthalmology Product) or Third Party(ies), and, as may be more specifically provided for in the Supply Agreement, Apellis shall allocate or
cause to be allocated available quantities of materials, Compound or capacity, to ensure that Sobi receives at least its pro rata share, taking
into account the needs of patients (including patient safety and the needs of patients relying on supply of Products for life saving purposes).

8.9

Manufacturing Process Costs

.

8.9.1

Cost Sharing. Each Party shall bear its pro rata share (based upon, prior to execution of the Supply Agreement, each
Party’s  anticipated  future  respective  demand  for  the  Product  and  any  Non-Systemic  Ophthalmology  Product  for  its
territory  and,  following  execution  of  the  Supply  Agreement,  as  provided  for  therein)  of  all  reasonable  Out-of-Pocket
Costs incurred by Apellis or any of its Affiliates in conducting process development, capital investments in facilities or
equipment, or other similar activities, including such activities intended to improve the Manufacturing process for, or
reduce  the  costs  of  Manufacturing,  any  Compound  or  Product  as  reasonably  substantiated  in  writing  in  advance  of
incurring  such  Out-of-Pocket  Costs  and  taking  into  account  the  Parties’  relative  Manufacturing  volumes  and
requirements (“Manufacturing Process Costs”), as long as:

(a)

Sobi’s share of such Manufacturing Process Costs and related activities:

(i)

are    (A)  for  Calendar  Year  2021  no  more  than  the  lesser  of  (1)  [**]  percent  ([**]%)  of  such
Manufacturing  Process  Costs  actually  incurred  by  Apellis  or  (2)  [**]  dollars  ($[**]))  (such
amount and a reasonable description of

76

 
 
 
 
 
such  corresponding  activities  are  set  forth  on  Schedule    8.9  (Estimated  Manufacturing  Process
Costs)), or (B) less than [**] dollars ($[**]) in any other given Calendar Year (such amounts set
forth in this clause (i) being deemed approved by Sobi); or

(ii)

except as set forth in clause (i), (A) with respect to any other estimated costs set forth on Schedule
8.9 (Estimated Manufacturing Process Costs), have been approved in writing by Sobi within [**]
after  the  Effective  Date  (or  such  later  date  by  which  Apellis  has  provided  reasonable
documentation to Sobi, as is customary for a public company to review in connection with such
investment, substantiating the business case and basis(es) for such Manufacturing Process Costs,
including the related risks and benefits thereof, and the Parties have had a reasonable opportunity
to discuss the extent of such development, investment, or activities and the costs related thereto)
or (B) are otherwise approved in advance in writing by Sobi; and

8.9.2

(b)

any quantifiable reduction in costs of the Manufacturing process is reflected in any Manufacturing Costs paid
by Sobi from and after the date of such reduction.

Sobi  shall  reimburse,  subject  to  this  Section  8.9  (Manufacturing  Process  Costs),  Apellis  for  its  share  of  such
Manufacturing Process Costs within [**] after receipt of any invoice therefor.

No  Cost  Sharing.  If  (x)  Apellis  proposes  undertaking  any  process  development,  capital  investments  in  facilities  or
equipment,  or  other  activities  to  improve  the  Manufacturing  process  for,  or  reduce  the  costs  of  Manufacturing,  any
Compound or Product in accordance with Section 8.9.1 (Cost Sharing) and (y) Sobi declines to bear (and is not deemed
to approve pursuant to Section 8.9.1(a)(i) (Cost Sharing)) its pro rata share of the Manufacturing Process Costs that will
be incurred in conducting such activities, then Apellis may refuse to permit Sobi to benefit from any improvements or
cost reductions resulting from such activities unless and until Sobi, at its sole election (after having been provided with
a  reasonably  detailed  summary  of  such  Manufacturing  Process  Costs  incurred  to  date  and  reasonably  expected  to  be
incurred thereafter), provides written notice to Apellis that it elects to bear Sobi’s pro rata share of the Manufacturing
Process Costs and pays Apellis [**] percent ([**]%) of Sobi’s pro rata share of such Manufacturing Process Costs that
Apellis has incurred as of the date that such notice is provided by Sobi to Apellis; provided, however, that, after Sobi
provides  such  notice,  and  provided  that  Sobi  pays  such  [**]  percent  ([**]%)  of  the  pro  rata  share  of  such
Manufacturing  Process  Costs,  Sobi  shall  bear  only  [**]  percent  ([**]%)  of  its  pro rata  share  of  such  Manufacturing
Process Costs incurred by Apellis after such notice is provided.

8.10

Regulatory  Disclosure  Fees.  If,  pursuant  to  the  terms  of  any  Apellis  Supply  Agreement,  any  party  to  such  Apellis  Supply
Agreement  charges  Apellis  a  fee  in  connection  with  the  disclosure  of  any  Know-How  relating  to  the  Manufacture  of  any
Compound or Product to any Regulatory Authority in the Sobi Territory, Sobi shall be solely responsible for such fee and shall
reimburse Apellis for any such fee within [**] after receipt of any invoice therefor.

8.11

Apellis  Supply  Agreement.  With  respect  to  each  Apellis  Supply  Agreement  negotiated  by  Apellis  after  the  Effective  Date,
Apellis shall use good faith efforts to permit Sobi to review and comment

77

 
 
 
 
 
 
on drafts of such Apellis Supply Agreement and shall consider all reasonable comments from Sobi regarding such Apellis Supply
Agreement in good faith.

Each royalty rate set forth in the table above will apply only to that portion of the aggregate Net Sales of Products in the
Sobi Territory during a given Calendar Year that falls within

80

 
 
 
 
 
 
 
 
 
the indicated portion. For example, if aggregate Net Sales of Products in the Sobi Territory in a given Calendar Year
were [**] Dollars ($[**]), then the royalties payable with respect to such Net Sales would be:

[**].

No  multiple  royalties  will  be  payable  under  this  Section  9.5  (Royalty  Payments)  regardless  of  the  number  of  Valid
Claims in any Apellis Patent Rights covering a Product.

9.5.2

Royalty Term.  Royalties payable under this Section 9.5 (Royalty Payments) shall be paid by Sobi on a Product-by-
Product and country-by-country basis from the Effective Date until the latest of:

(a)

(b)

(c)

expiration  of  the  last-to-expire  Valid  Claim  in  the  Apellis  Patent  Rights  (for  the  avoidance  of  doubt,
including Joint Patent Rights) Covering such Product in such country;

ten (10) years following the First Commercial Sale of such Product in such country; and

the expiration of all Regulatory Exclusivity for such Product in such country;

(each such term with respect to a Product in a country, a “Royalty Term”); except that, notwithstanding anything to the
contrary  in  this  Agreement,  if  at  any  time  (i)  the  Royalty  Term  for  a  Product  and  country  in  the  Sobi  Territory  has
expired (and, for the avoidance of doubt, all Valid Claims as defined under this Agreement Covering such Product in
such country have expired) but (ii) because there is a pending Valid Claim (as defined in the Penn Other Fields License)
that has been pending for more than [**], Apellis owes Penn a royalty for Sales (as defined in the Penn Other Fields
License) of such Product in such country under the Penn Other Fields License, then Sobi shall report and pay to Apellis
royalties on such Sales of Products in the Sobi Territory equal to the royalties owed by Apellis to Penn for such Sales
under the Penn Other Fields License.

9.5.3

Royalty Reduction.

(a)

(b)

(c)

On  a  Product-by-Product  and  country-by-country  basis,  subject  to  Section  9.5.3(d)  (Royalty  Reduction),
during any period in which (i) such Product in such country is not Covered by a Valid Claim in the Apellis
Patent Rights (for the avoidance of doubt, including Joint Patent Rights) in the applicable country and (ii)
there is no Regulatory Exclusivity with respect to such Product in such country, the royalty rate with respect
to  such  Product  in  such  country  will  be  reduced  to  [**]  percent  ([**]%)  of  the  applicable  rate  set  forth  in
Section 9.5.1 (Royalty Rate).

On  a  Product-by-Product  and  country-by-country  basis,  subject  to  Section  9.5.3(d)  (Royalty  Reduction),
Sobi may deduct from the royalties otherwise owed to Apellis pursuant to Section 9.5.1 (Royalty Rate) with
respect to such Product in such country, [**] percent ([**]%) of any Third Party Payments paid by Sobi with
respect to such Product in such country.

On a Product-by-Product and country-by-country basis, if, during any Calendar Quarter during the Royalty
Term for such Product in such country:

81

 
 
 
 
 
 
 
 
 
 
(i)

there are one (1) or more Generic Products or Biosimilar Products being sold in such country with
respect to such Product; and

(ii)

either:

A.

B.

such Generic Product(s) or Biosimilar Product(s), by unit equivalent volume
in such country, exceed a [**] percent ([**]%) share of the aggregate market
in  such  country  of  such  Product  and  all  such  Generic  Product(s)  or
Biosimilar  Product(s)  (based  on  the  number  of  units  of  such  Product  and
such  Generic  Product(s)  or  Biosimilar  Product(s)  in  the  aggregate  sold  in
such country, as reported by a well-known reporting service agreed between
the Parties acting reasonably (e.g., [**])); or

as a result of competition from Generic Products or Biosimilar Products in
such  country,  the  Net  Sales  of  such  Product  are  reduced  by  [**]  percent
([**]%)  in  a  Calendar  Quarter  when  compared  to  the  Calendar  Quarter
before  the  entry  of  the  relevant  Generic  Product  or  Biosimilar  Product  in
such country,

then, subject to Section 9.5.3(d) (Royalty Reduction), the royalty rates payable under this Agreement with
respect to such Product in such country for such Calendar Quarter shall be reduced to [**] percent ([**]%)
of  the  applicable  rate  set  forth  in  Section  9.5.1  (Royalty  Rate)  and  Sobi  shall  not  be  in  breach  of  its
obligations under Section 6.2 (Commercialization Diligence Obligations) if Sobi ceases or reduces its efforts
to actively market or promote such Product in such country following the entry of such Generic Product or
Biosimilar  Product,  as  long  as  such  cessation  or  reduction  satisfies  the  definition  of  Commercially
Reasonable Efforts under the circumstances. For purposes of this Section 9.5.3(c) (Royalty Reduction), (X)
“Generic Product” means, in a particular country with respect to a Product regulated as a drug product, any
drug    product  that:  (1)  contains  the  same  active  ingredient  as  the  Product;  (2)  has  received  all  necessary
approvals by the applicable Regulatory Authorities authorizing the marketing and sale of such product as a
drug product; (3) is marketed or sold by a Third Party that has not obtained the rights to market or sell such
product as a licensee, sublicensee or distributor of Sobi or any of its Affiliates or Sublicensees with respect
to  such  product,  other  than  as  a  result  of  settlement  of  any  litigation;  and  (4)  is  approved  for  use  in  such
country  pursuant  to  an  abbreviated  regulatory  approval  process  governing  approval  of  follow-on  drug
products  based  on  the  then-current  standards  for  regulatory  approval  in  such  country  (e.g.,  a  non-U.S.
equivalent to an abbreviated new drug application submitted pursuant to Section 505(j) of the FD&C Act (21
U.S.C. 355(j)), a new drug application submitted pursuant to Section 505(b)(2) of the FD&C Act (21 U.S.C.
355(b)(2)),  or  a  relevant  equivalent  under  foreign  law)  and  where  such  regulatory  approval  was  based  in
whole or in part upon the findings by the Regulatory Authority of clinical safety and efficacy based on data
generated by Sobi (or its Affiliate or Sublicensee) or Apellis (or its Affiliate or sublicensee) included in a
Regulatory Submission for Regulatory Approval in a particular country with respect to the Product, and (Y)
“Biosimilar Product” means, in a particular country with respect to a Product regulated as a

82

 
 
 
 
 
 
biological product, any biological product that: (I) has received all necessary approvals and licensures by the
applicable Regulatory Authorities in such country to market and sell such product as a biosimilar product;
(II)  is  marketed  or  sold  by  a  Third  Party  that  is  not  a  Sublicensee,  other  than  a  Sublicensee  who  is  a
Sublicensee as a result of settlement of any litigation; and (III) is approved as a (1) (1) “similar biological
medicinal product”  with respect to which such Product is the “reference medicinal product,” or (2) if not in
the European Union, as the foreign equivalent of a “biosimilar” or “similar biological medicinal product” of
such Product; in each case ((1)-(2)), for use in such country pursuant to an abbreviated regulatory approval
process  governing  approval  of  biosimilars  based  on  the  then-current  standards  for  regulatory  approval  in
such  country  (and  where  such  regulatory  approval  was  based  in  part  upon  findings  by  the  Regulatory
Authority  of  clinical  safety  and  efficacy  based  on  clinical  data  generated  by  Sobi  (or  its  Affiliate  or
Sublicensee) or Apellis (or its Affiliate or sublicensee) with respect to such Product.

(d)

In  no  event  shall  the  royalty  reductions  described  in  this  Section  9.5.3  (Royalty  Reduction),  alone  or
together, reduce the royalties payable by Sobi for a Product in a country in any given Calendar Quarter to
less than [**] percent ([**]%) of the amounts otherwise payable by Sobi for such Product in such country in
such Calendar Quarter pursuant to Section 9.5.1 (Royalty Rate).  Sobi may carry over and apply any such
royalty reductions that are incurred or accrued in a Calendar Quarter and are not deducted in such Calendar
Quarter due to the limitation set forth in the first sentence of this Section 9.5.3(d) (Royalty Reduction), to
any  subsequent  Calendar  Quarter(s)  and  shall  begin  applying  such  reductions  to  such  royalties  as  soon  as
practicable and continue applying such reductions on a Calendar Quarter basis thereafter until fully deducted,
in  all  cases  subject  to  the  limitation  set  forth  in  the  first  sentence  of  this  Section  9.5.3(d)  (Royalty
Reduction).

9.5.4

9.5.5

Expiration  of  Royalty  Term.    Upon  the  expiration  of  the  Royalty  Term  with  respect  to  a  Product  in  a  country,  the
license granted by Apellis to Sobi pursuant to Section 2.1.1(a)(ii) (License Grants to Sobi) with respect to such Product
in such country shall be deemed to be fully paid-up, royalty-free, non-terminable, irrevocable, and perpetual, but, solely
following the expiration of the applicable Royalty Term, Sobi shall (in accordance with a plan agreed by the Parties at
such time in good faith) assume and be solely responsible for any outstanding amounts payable to Apellis’ Third Party
licensors (including Penn, as set forth in Section 9.5.2 (Royalty Term)) to the extent related to the Sobi Territory (and
for clarity, Apellis shall continue to be responsible for any outstanding amounts related to the Apellis Territory).

Royalty Reports; Payments.  Sobi shall, within [**] following the end of each Calendar Quarter, provide Apellis with
a  good  faith  estimate  of  royalties  that  will  be  paid  to  Apellis  under  this  Agreement  for  such  Calendar  Quarter.  Sobi
shall, within [**] following the end of each Calendar Quarter in which a royalty payment accrues, (a) provide to Apellis
a  report  specifying  for  such  Calendar  Quarter:  the  number  units  of  each  Product  sold  by  Sobi,  its  Affiliates  or  its
Sublicensees on which royalty payments are owed to Apellis; subject to Sobi using Commercially Reasonably Efforts to
procure the same, the number of units of Each Product sold by any Functional Sublicensee on which royalty payments
are  owed  to  Apellis;  the  gross  amount  received  for  such  sales  (with  gross  amount  received  for  sales  by  Functional
Sublicensees broken out separately, where such information is available); the

83

 
 
 
 
 
Net Sales during such Calendar Quarter, including any deductions taken as permitted under such definition, listed by
category  of  cost,  with  Net  Sales  received  for  sales  by  Functional  Sublicensees  broken  out  separately,  where  such
information  is  available;  the  amount  of  any  credits  or  reductions,  if  any,  taken  or  made  pursuant  to  Section  9.5.3
(Royalty  Reductions);  the  calculation  of  the  royalty  payable  to  Apellis  for  such  Net  Sales  pursuant  to  Section  9.5
(Royalty Payments); the applicable exchange rate to convert from each country’s currency to U.S. Dollars under Section
9.9 (Currency Conversion); and the royalty calculation and royalties payable in U.S. Dollars, and (b) make the royalty
payments owed to Apellis hereunder in accordance with such royalty report in arrears. If Sobi is not able to obtain any
information set forth in this Section 9.5.5 (Royalty Reports; Payments) regarding Functional Sublicensee sales despite
Sobi  having  used  Commercially  Reasonable  Efforts  to  obtain  it,  and  the  Parties  are  unable  to  agree  upon  such
information, the Parties shall submit such dispute for resolution to a mutually agreed independent accounting expert,
whose decision will be final and binding on the Parties and shall be deemed included in the applicable royalty report(s).
In  addition,  at  Apellis’  reasonable  request,  Sobi  shall  cooperate  with  Apellis  in  good  faith  to  provide  Penn  any
additional royalty-related information reasonably requested or required by Penn under the Penn Other Fields License
Agreement.  Without  prejudice  to  Article  13  (Confidentiality),  Apellis  undertakes  to  maintain  as  Sobi’s  Confidential
Information all information regarding royalties and royalty estimates furnished by Sobi hereunder, except that Apellis
shall  be  entitled  to  disclose  such  information  in  its  quarterly  reports  (i)  aggregated  with  other  information  in  such
manner  that  the  information  regarding  royalties  and  royalty  estimates  cannot  be  identified  as  relating  to  Sobi  or  (ii)
following  Sobi’s  disclosure  of  its  full  royalty  report  within  [**]  following  the  end  of  each  Calendar  Quarter.  Apellis
acknowledges that information regarding royalties and royalty estimates may constitute inside information in relation to
Sobi.

Penn Other Fields License Agreement. As between the Parties, Apellis is solely responsible for all amounts payable
under the Penn Other Fields License Agreement with respect to the Development, Manufacture, or Commercialization
of any Compound or Product worldwide.

Collaboration In-Licenses.  The  costs  of  each  Collaboration  In-License,  to  the  extent  the  costs  directly  relate  to  the
Development,  Manufacture,  or  Commercialization  of  Products  in  the  Apellis  Territory,  or  to  the  Development,
Manufacture, or Commercialization of any Non-Systemic Ophthalmology Product anywhere in the world, shall be paid
by  Apellis.  The  costs  of  each  Collaboration  In-License,  to  the  extent  the  costs  directly  relate  to  the  Development,
Manufacture, or Commercialization of Products in the Sobi Territory shall be paid by Sobi, subject to deduction from
royalties to the extent set forth in Section 9.5.3(b) (Royalty Reduction). To the extent the costs of any Collaboration In-
License relate to both (a) the Development, Manufacture, or Commercialization of Products in the Apellis Territory or
Non-Systemic  Ophthalmology  Products  anywhere  in  the  world,  on  the  one  hand,  and  (b)  the  Development,
Manufacture,  or  Commercialization  of  Products  in  the  Sobi  Territory,  on  the  other  hand,  such  costs  shall  be  fairly
apportioned between the Parties, and each Party shall reimburse the other Party for its share of such costs within [**]

9.7.1

Taxes and Withholding.  Except as expressly set forth in this Section 9.7 (Taxes and Withholding; VAT), each Party
shall pay any and all taxes levied on account of all payments it receives under this Agreement. Each Party shall provide
such information and documentation to the other Party as are reasonably requested by such other Party to determine if
any  withholding  taxes  apply  to  any  payments  to  be  made  by  such  other  Party  under  this  Agreement  and  to  establish
qualification for a reduced withholding rate or an exemption from such withholding tax under the applicable bilateral
income tax treaty or relevant statutory provision. If a Party believes that it is required to withhold taxes on a payment to
the  other  Party,  the  paying  Party  shall  notify  the  other  Party  of  such  determination  no  less  than  [**]  prior  to  making
such  payment.  To  the  extent  that  Applicable  Laws  require  that  taxes  be  withheld  with  respect  to  any  payments  to  be
made  by  a  Party  to  the  other  Party  under  this  Agreement,  the  paying  Party  shall:  (a)  deduct  those  taxes  from  the
remittable payment, (b) pay the taxes to the proper taxing authority, and (c) send evidence of the obligation together
with proof of tax payment to the other Party on a reasonable and timely basis following such tax payment.  Each Party
agrees  to  cooperate  with  the  other  Party  in  claiming  refunds,  reductions,  or  exemptions  from  such  deductions  or
withholdings under any relevant agreement or treaty that is in effect. Notwithstanding anything to the contrary in this
Agreement, in the event a Party redomiciles, assigns its rights or obligations under Section 17.1 (Assignment) of this
Agreement, (each, a “Tax Action” and such Party, the “Acting Party”), and, as a result of such Tax Action, the amount
of tax required to be withheld under this Section 9.7.1 (Taxes and Withholding) in respect of a payment to the other
Party  (the  “Non-Acting Party”)  is  greater  than  the  amount  of  such  tax  that  would  have  been  required  to  have  been
withheld absent such Tax Action (for the sake of clarification, based on current law (including the double tax treaties
between (i) Sweden and the United States and (ii) Sweden and Switzerland), the Parties anticipate a zero percent (0%)
rate of withholding for payments made under this Agreement (i.e., before taking into account any Tax Action taken by
any  Party))),  then  any  such  amount  payable  to  the  Non-Acting  Party  shall  be  adjusted  to  take  into  account  such
withholding taxes as may be necessary so that, after making all required withholdings or credits, the Non-Acting Party
receives an amount equal to the sum it would have received had no such Tax Action occurred. The obligation to adjust
payments pursuant to the preceding sentence shall not apply, however, to the extent such increased withholding tax (i)
would  not  have  been  imposed  but  for  a  Tax  Action  taken  by  the  Party  receiving  the  payment  subject  to  withholding
under this Section 9.7.1 (Taxes and Withholding) or (ii) is attributable to the failure by the Non-Acting Party to comply
with  the  requirements  of  this  Section  9.7.1  (Taxes  and  Withholding).  For  purposes  of  this  Section  9.7.1  (Taxes  and
Withholding), a “redomiciliation” shall include a reincorporation or other action resulting in a change in tax residence
of the applicable Party or its assignee.  

9.7.2

VAT.  Notwithstanding anything to the contrary in this Agreement (including anything to the contrary in Section 9.7.1
(Taxes  and  Withholding)),  this  Section  9.7.2  (VAT)  shall  apply  with  respect  to  value  added  tax  or  any  similar  tax
(“VAT”). All amounts agreed by the Parties under this Agreement are exclusive of VAT. If, under Applicable Law, any
VAT is required to be paid in respect of any supply of goods or services under this Agreement, the Party receiving such
supply  of  goods  or  services  shall  pay  VAT  at  the  applicable  rate  either  (i)  to  the  other  Party  or,  if  provided  under
Applicable Law, (ii) directly to the relevant tax authorities. In each case, the Party providing such supply of goods or
services shall issue valid VAT invoice to the other Party in respect of the supply of goods or services.

9.8.2

Late Payments. Subject to Section 9.8.2 (Disputed Payments), any amount owed by a Party to the other Party under
this Agreement that is not paid on or before the date such payment is due shall bear interest at a rate per annum equal to
the lesser of (a) the Prime Rate in effect during the period in which such payment is overdue, as published by the Wall
Street Journal, plus [**], and (b) the highest rate allowed by Applicable Law, in each case ((a) or (b)), such interest to
run from the date on which payment of such sum became due until payment thereof in full together with such interest;
except  that,  subject  to  Section  9.8.2  (Disputed  Payments),  if  Sobi  has  not  paid  Apellis  any  amount  owed  under  this
Agreement within [**] of the date of Sobi’s receipt of a relevant breach notice, the applicable interest rate per annum
will be equal to the lesser of (x) [**] the Prime Rate in effect during the period in which such payment is overdue, as
published  by  the  Wall  Street  Journal,  plus  [**],  and  (y)  the  highest  rate  allowed  by  Applicable  Law,  for  the  period
commencing  on  the  [**]  following  Sobi’s  receipt  of  such  breach  notice  until  the  earlier  of  (i)  payment  in  full  of  the
applicable undisputed amounts by Sobi and (ii) the effective date of any termination of this Agreement.

Disputed  Payments.  If  a  dispute  arises  between  the  Parties,  each  acting  in  good  faith,  in  respect  of  any  part  of  an
invoice, the disputing Party shall notify the other Party promptly in writing with particulars of such dispute and shall be
entitled to withhold payment of the so disputed part of the invoice. Each Party shall use reasonable efforts to promptly
and  in  good  faith  resolve  the  dispute  in  accordance  with  Article  16  (Dispute  Resolution).  Payment  of  any  disputed
amounts (together with any interest calculated in accordance with Section 9.8.1 (Late Payments)) shall be made within
[**]  following  the  resolution  of  such  dispute,  and,  unless  the  arbitrators  determine  upon  a  preponderance  of  the
evidence that the paying Party withheld the disputed payment in bad faith (where such burden of proof shall rest solely
with the payee Party), the payee Party may not use such withholding as a basis for terminating this Agreement pursuant
to Section 14.2 (Termination for Breach).

9.9

Currency Conversion

.  Each Party shall use its then-current standard exchange rate methodology, as applied in its external reporting, for the translation
of  foreign  currency  transactions  into  Dollars  under  this  Agreement.  Each  Party  shall  give  the  other  Party  prompt  written  notice  of  any
changes  to  such  Party’s  customary  and  usual  procedures  for  currency  conversion,  which  shall  only  apply  (a)  after  such  notice  has  been
delivered and (b) if the changes continue to maintain a set methodology for currency conversion.

9.10

Blocked Payments

.  If, by reason of Applicable Law in any country, it becomes impossible or illegal for a Party or any of its applicable Affiliates or
Sublicensees to transfer, or have transferred on its behalf, any payments to the other Party, the payor Party shall promptly notify the payee
Party  of  the  conditions  preventing  such  transfer  and  such  royalties  or  other  payments  shall  be  deposited  in  local  currency  in  the  relevant
country to the credit of the payee Party in a recognized banking institution designated by the payee Party or, if none is designated by the
payee Party within a period of [**], in a recognized banking institution selected by the payor Party and identified in a notice given to the
payee Party pursuant to Section 17.8 (Notices).

9.11

Payment Method

.    All  payments  to  be  made  by  a  Party  to  the  other  Party  under  this  Agreement  shall  be  made  in  Dollars  by  wire  transfer  in

complete  and  accurate  books,  records,  and  related  background  information  pertaining  to  Shared  Development  Costs,
and  Sobi  shall  keep  (and  shall  cause  its  Affiliates,  sub/licensees,  and  Sublicensees  to  keep)  complete  and  accurate
books, records, and related background information pertaining to Initial Development Costs, PNH Development Costs,
Net  Sales  and  their  calculation    hereunder,  in  each  case  in  reasonable  detail  to  permit  the  other  Party  to  confirm  the
accuracy of all payments made or required to be paid hereunder for at least the preceding [**].

9.12.2

Party Audits.  

(a)

(b)

Upon reasonable (but in any case no less than [**]) advance notice by a Party (the “Auditing Party”) to the
other  Party  (the  “Audited Party”),  and  not  more  than  [**]  and  [**]  (in  each  case,  except  for  cause),  the
Audited  Party  and  its  Affiliates  will  permit,  and  Sobi  will  cause  its  sub/licensees  and  Sublicensees  (as
applicable) to permit, an independent certified public accounting firm of internationally recognized standing,
selected by the Auditing Party and reasonably acceptable to the Audited Party, to have access during normal
business hours to such of the records of the Audited Party and its Affiliates and, if applicable, sub/licensees
and Sublicensees, as may be reasonably necessary to verify the accuracy of any payments made or required
to be made under this Agreement (including with respect to any costs and expenses incurred by a Proposing
Party under Section 4.4.4(b)(iii) (Buy-In)), for any year ending not more than [**] prior to the date of such
request. The accounting firm will enter into a confidentiality agreement reasonably acceptable to the Audited
Party  governing  the  use  and  disclosure  of  the  Audited  Party’s  and  its  Affiliates’,  sub/licensees,  and
Sublicensees’  information  disclosed  to  such  firm,  and  such  firm  will  disclose  to  the  Auditing  Party  only
whether  the  payments  made  under  this  Agreement  were  accurate  and  the  specific  details  concerning  any
discrepancies.

Any  disputes  with  respect  to  the  findings  of  such  accounting  firm  may  be  referred  by  either  Party  to  the
dispute  resolution  procedure  set  forth  in  Article  16  (Dispute  Resolution).  If  Sobi  is  found  to  have  been
underpaid any amounts payable to Apellis hereunder, then Apellis shall be entitled to recover any undisputed
discrepancy no later than [**] after delivery to the Parties of the final report from such accounting firm. If
either Party is found to have overcharged the other Party for any Shared Development Costs hereunder, then
the other Party shall be entitled to recover any undisputed overpayment no later than [**] after delivery to
the Parties of the final report from such accounting firm. The fees charged by such accounting firm shall be
paid by the Auditing Party, except that, if the audit discloses a net underpayment or overcharging of amounts
owed of more than [**] percent ([**]%) of total amounts owed or supposed to be charged by the Audited
Party for any Calendar Year period covered by the audit, then the Audited Party shall pay the reasonable fees
and  expenses  charged  by  such  accounting  firm.    The  Auditing  Party  shall  treat  all  financial  information
disclosed by its accounting firm pursuant to this Section 9.12 (Financial Audits) as Confidential Information
of the Audited Party for purposes of Article 13 (Confidentiality), and shall cause its accounting firm to do the
same.

reasonably  acceptable  to  Sobi  with  access  to  all  of  the  books,  records,  and  related  background  information  required  by  Section  9.12.1
(Records Retention) to conduct a review or audit of Sales (as defined in the Penn Other Fields License Agreement), Net Sales (as defined in
the Penn Other Fields License Agreement), and all of the royalties, fees, and other payments payable under the Penn Other Fields License
Agreement.  Access  shall  be  made  available:  (a)  during  normal  business  hours;  (b)  in  a  manner  reasonably  designed  to  facilitate  Penn’s
review or audit without unreasonable disruption to the audited Person’s business; and (c) no more than [**] during the Term (as defined in
the  Penn  Other  Fields  License  Agreement)  and  for  a  period  of  [**]  thereafter.  Sobi  shall  promptly  pay  to  Apellis  the  amount  of  any
underpayment determined by the review or audit, plus accrued interest as calculated under the Penn Other Fields License Agreement. If the
review or audit determines that, as a result of an under-reporting or underpayment by Sobi or any of its Affiliates or Sublicensees to Apellis,
Apellis has underpaid to Penn any payment under the Penn Other Fields License Agreement by [**] percent ([**]%) or more, then Sobi shall
also reimburse Apellis an amount equivalent to the amount Apellis is obliged to pay to Penn under the Penn Other Fields License Agreement
in respect of the costs and expenses of Penn and its accountants in connection with such review or audit. Apellis shall use reasonable efforts
to coordinate any Apellis audit with any Penn audit pursuant to this Section 9.12.3 (Penn Audits) to minimize disruption to the Sobi business.

As of the Effective Date, pursuant to section 7.1 of the Penn Other Fields License Agreement, Penn controls
the preparation, prosecution and maintenance of the Penn Patent Rights (as defined in the Penn Other Fields
License Agreement) and the selection of patent counsel, with input from Apellis.

As between the Parties, Apellis will have the first right (but not the obligation) to prepare, file, prosecute,
and  maintain  (collectively,  “Prosecute”)  (i)  all  Apellis  Patent  Rights,  other  than  Joint  Patent  Rights,  in
Apellis’ name and (ii) all Joint Patent Rights in both Parties’ names. Subject to Section 11.5.3(f) (Additional
Covenants of Apellis), in the event that Apellis declines to Prosecute any Apellis Patent Rights, other than
Joint Patent Rights, in the Sobi Territory or any Joint

89

 
 
 
 
 
 
 
 
(c)

(d)

Patent  Rights,  it  shall  give  Sobi  reasonable  notice  to  this  effect,  sufficiently  in  advance  to  permit  Sobi  to
undertake such Prosecution in any applicable country without a loss of rights, and thereafter Sobi may, upon
written notice to Apellis, Prosecute such Patent Rights in the owning Party(ies)’ name(s).

As  between  the  Parties,  Sobi  will  have  the  sole  right  (but  not  the  obligation)  to  Prosecute  the  Sobi  Patent
Rights, other than Joint Patent Rights, in Sobi’s name.

The  Party  Prosecuting  any  given  Apellis  Patent  Rights  or  Sobi  Patent  Rights  (for  the  avoidance  of  doubt,
including Joint Patent Rights) (the “Prosecuting Party”) shall keep the other Party reasonably informed as
to material developments with respect to the Prosecution of such Patent Rights that encompass any Product
specifically or generically. The Prosecuting Party shall (i) provide the other Party the timely opportunity to
have  reasonable  input  into  the  strategic  aspects  of  such  Prosecution  and  shall  consider  such  other  Party’s
input with respect to such strategic aspects in good faith, (ii) promptly provide to the other Party drafts of all
material patent-related filings and communications related to such Patent Rights, including copies of office
actions or other correspondence that the Prosecuting Party receives from any patent office, drafts of office
action responses, and other material correspondence that the Prosecuting Party provides to any patent office,

(c)

As  between  the  Parties,  Apellis  will  have  the  first  right  (but  not  the  obligation)  to  defend  against  any
declaratory  judgment  action,  inter  partes  review,  opposition  proceeding,  interference,  or  other  action
challenging  any  Apellis  Patent  Right  (for  the  avoidance  of  doubt,  including  any  Joint  Patent  Right),  other
than with respect to (i) any counter‑claims or defenses in any enforcement action brought by Sobi pursuant to
Section10.3  (Intellectual  Property  Enforcement),  or  (ii)  any  action  by  a  Third  Party  in  response  to  an
enforcement action brought by Sobi to Section 10.3 (Intellectual Property Enforcement), which, in both cases
((i) and (ii)), will be controlled by Sobi. In the event that Apellis declines to defend any Apellis Patent Rights
in the Sobi Territory or any Joint Patent Rights anywhere in the world, it shall give Sobi reasonable notice to
this  effect,  sufficiently  in  advance  to  permit  Sobi  to  undertake  such  defense  in  any  applicable  country
without a loss of rights, and thereafter Sobi may, upon written notice to Apellis, defend such Patent Rights.

As  between  the  Parties,  Sobi  will  have  the  sole  right  (but  not  the  obligation)  to  defend  against  any
declaratory  judgment  action,  inter  partes  review,  opposition  proceeding,  interference,  or  other  action
challenging any Sobi Patent Right other than any Joint Patent Right.

The  Party  defending  any  given  Apellis  Patent  Rights  or  Sobi  Patent  Rights  (for  the  avoidance  of  doubt,
including Joint Patent Rights) (the “Defending Party”) shall keep the other Party reasonably informed as to
material  developments  with  respect  to  the  defense  of  such  Patent  Rights  that  encompass  any  Product
specifically or

90

 
 
 
 
 
 
 
 
 
generically. The Defending Party shall (i) provide the other Party the timely opportunity to have reasonable
input into the strategic aspects of such defense and shall consider the other Party’s input with respect to such
strategic aspects in good faith, (ii) promptly provide to the other Party drafts of all defense-related notices
and documents related to such Patent Rights, including copies of notices or documents that the Defending
Party  receives  from  any  Governmental  Authority  or  counterparty,  drafts  of  filings  or  responses,  or  other
documents that the Defending Party provides to any Governmental Authority or counterparty, in each case,
for the other Party’s review and comment, and (iii) consider in good faith any reasonable comments timely
provided by the other Party with respect to such notices and documents.

10.2.3

Cooperation.  The non-Prosecuting Party or non-Defending Party shall (a) obtain and deliver to the Prosecuting Party
or  Defending  Party  (as  applicable)  any  necessary  documents  for  the  Prosecuting  Party  or  Defending  Party  (as
applicable)  to  exercise  its  rights  to  Prosecute  or  defend  (as  applicable)  all  Patent  Rights  pursuant  to  Section  10.2.1
(Prosecution Rights) or Section 10.2.2 (Defense of Patent Rights) (as applicable), (b) render all signatures that will be
necessary  in  connection  with  any  filings  and  documents  in  connection  with  such  Prosecution  and  defense,  and  (c)
cooperate with and assist the Prosecuting Party or Defending Party (as applicable) in all other reasonable ways that are
necessary  for  the  Prosecution  or  defense  of  such  Patent  Rights  (including  with  respect  to  assignments,  declarations,
filing divisionals or continuations, or otherwise).

10.2.4

Other  Prosecution  and  Defense.    Except  as  expressly  set  forth  in  this  Section  10.2  (Prosecution  and  Defense),  as
between  the  Parties,  each  Party  will  have  the  sole  right,  in  its  sole  discretion,  to  Prosecute  and  defend  against  a
declaratory judgment action, inter partes review, opposition proceeding, interference, or other action challenging, any
Patent Rights owned or Controlled by such Party, at such Party’s sole cost and expense.

10.2.5

Costs. Each Party will solely bear all costs and expenses incurred by such Party with respect to Prosecution or defense
of any Apellis Patent Rights or Sobi Patent Rights (for the avoidance of doubt, including Joint Patent Rights).

10.3.1

Notice.    If  Apellis  receives  notice  of,  or  otherwise  becomes  aware  of,  any  alleged  or  threatened  infringement  or
misappropriation of any Apellis Technology (for the avoidance of doubt, including any Joint Technology) by a Third
Party that is competitive with a Product (“Competitive Infringement”) anywhere in the world, it shall promptly notify
Sobi  thereof.  If  Sobi  receives  notice  of,  or  otherwise  becomes  aware  of,  any  alleged  or  threatened  Competitive
Infringement anywhere in the world, it shall promptly notify Apellis thereof.

10.3.2

Enforcement of Technology.

(a)

Apellis  shall  use  reasonable  efforts  to  obtain  for  Sobi  the  right  to  exercise  (or,  to  the  extent  that  it  cannot
obtain such right despite the use of reasonable efforts, shall exercise at Sobi’s expense and direction) Apellis’
right to enforce the Penn Patent Rights (as defined in the Penn Other Fields License Agreement) against any
Competitive  Infringement  in  the  Sobi  Territory  in  accordance  with  the  provisions  of  Article  8  of  the  Penn
Other Fields License Agreement. To the extent that Apellis

91

 
 
 
 
 
 
 
 
 
(b)

is able to obtain for Sobi the right to exercise Apellis’ right to enforce the Penn Patent Rights (as defined in
the  Penn  Other  Fields  License  Agreement)  against  any  Competitive  Infringement  in  the  Sobi  Territory  in
accordance with the provisions of Article 8 of the Penn Other Fields License Agreement, Sobi will have the
initial  right,  but  not  the  obligation,  to  initiate  a  suit  or  take  other  appropriate  action  that  Sobi  believes  is
reasonably  required  to  enforce  the  Apellis  Technology  (for  the  avoidance  of  doubt,  including  any  Joint
Technology)  against  any  Competitive  Infringement  in  the  Sobi  Territory.  Sobi  shall  give  Apellis  advance
notice of Sobi’s intent to file any such suit or take any such action and the reasons therefor, and shall provide
Apellis  with  a  reasonable  opportunity  to  make  suggestions  and  comments  regarding  such  suit  or  action,
which  Sobi  shall  consider  in  good  faith.    Thereafter,  Sobi  shall,  acting  reasonably,  determine  whether  to
diligently  pursue  such  suit  or  take  some  other  action  and  shall  keep  Apellis  promptly  informed,  and  shall
from time to time consult with Apellis regarding the status of such suit or action and, to the extent permitted
by any protective order and permitted by Applicable Law, shall provide Apellis with copies of all material
documents (e.g.,  complaints,  answers,  counterclaims,  material  motions,  orders  of  the  court,  memoranda  of
law and legal briefs, interrogatory responses, depositions, material pre-trial filings, expert reports, affidavits
filed  in  court,  transcripts  of  hearings  and  trial  testimony,  trial  exhibits  and  notices  of  appeal)  filed  in,  or
otherwise relating to, such suit or action.  Apellis shall have the right to participate and be represented in any
such  suit  by  its  own  counsel  at  its  own  expense  (and  such  expenses  shall  not  be  reimbursed  pursuant  to
Section 10.3.2(e) (Enforcement of Technology)).

If Sobi fails to initiate a suit or take such other appropriate action under Section 10.3.2(a) (Enforcement of
Technology)  at  least  [**]  prior  to  any  deadline  on  which  initiation  of  a  suit  or  other  appropriate  action  is
required to avoid limiting or compromising the remedies (including monetary relief and stay of regulatory
approval) available against the applicable alleged Third Party infringer, then Apellis may, in its discretion,
provide Sobi with written notice of Apellis’ intent to initiate a suit or take other appropriate action to combat
such infringement or unauthorized use or misappropriation (as applicable).  If Apellis provides such notice,
then  Apellis  shall  have  the  right,  but  not  the  obligation,  to  initiate  a  suit  or  initiate  or  take  such  other
appropriate action that it believes is reasonably required to protect the applicable Apellis Technology from
such  infringement  or  unauthorized  use  or  misappropriation.    Apellis  shall  give  Sobi  advance  notice  of
Apellis’ intent to file any such suit or take any such action and the reasons therefor and shall provide Sobi
with  an  opportunity  to  make  suggestions  and  comments  regarding  such  suit  or  action,  which  Apellis  shall
consider in good faith.  Thereafter, Apellis shall keep Sobi promptly informed and shall from time to time
consult  with  Sobi  regarding  the  status  of  any  such  suit  or  action  and  shall  provide  Sobi  with  copies  of  all
material  documents  (e.g.,  complaints,  answers,  counterclaims,  material  motions,  orders  of  the  court,
memoranda  of  law  and  legal  briefs,  interrogatory  responses,  depositions,  material  pre-trial  filings,  expert
reports,  affidavits  filed  in  court,  transcripts  of  hearings  and  trial  testimony,  trial  exhibits  and  notices  of
appeal) filed in, or otherwise relating to, such suit or action. Sobi shall have the right to participate and be

(e)

Other than with respect to Competitive Infringement in the Sobi Territory, Apellis will have the sole right,
but  not  the  obligation,  to  initiate  a  suit  or  take  other  appropriate  action  that  Apellis  believes  is  reasonably
required  to  enforce  the  Apellis  Technology  (for  the  avoidance  of  doubt,  including  any  Joint  Technology)
against  any  infringement  or  unauthorized  use  or  misappropriation  by  a  Third  Party.  For  clarity,  Sobi  will
have the sole right, but not the obligation, to initiate a suit or take other appropriate action that Sobi believes
is reasonably required to enforce the Sobi Technology that is not Joint Technology against any infringement
anywhere in the world.

If required under Applicable Law in order for a Party to initiate or maintain any suit in accordance with this
Section 10.3.2 (Enforcement of Technology), the other Party shall join as a party to the suit.  If requested by
the  Party  initiating  suit,  the  other  Party  shall  provide  reasonable  assistance  to  the  Party  initiating  suit  in
connection therewith, and the requesting Party shall reimburse the other Party for all reasonable costs and
expenses  incurred  by  the  other  Party  in  providing  such  assistance  within  [**]  after  receipt  of  any  invoice
therefor.  The  Party  initiating  suit  shall  assume  and  pay  all  of  its  own  Out-of-Pocket  Costs  incurred  in
connection with any litigation or proceedings described in this Section 10.3.2 (Enforcement of Technology),
including the fees and expenses of the counsel selected by it.

Any damages or other monetary awards recovered in any action, suit, or proceeding brought in accordance
with this Section  10.3.2 (Enforcement of Technology) shall first, to the extent the action, suit, or proceeding
involved any Patent Rights licensed under the Penn Other Fields License Agreement, be applied as set forth
in section 8.2 of the Penn Other Fields License Agreement (i.e., first, applied to reimburse Apellis and its
Affiliates, Sobi and its Sublicensees, and Penn for their Litigation Expenses (as defined in the Penn Other
Fields License Agreement), and, second, as to any remainder, if such litigation is brought by Apellis or any
of its Affiliates, [**] percent ([**]%) shall be paid to Apellis and its Affiliates and [**] percent ([**]%) shall
be paid to Penn) and, second, be applied to reimburse each Party for all of the reasonable attorneys’ fees or
expenses,  whether  incurred  directly  or  indirectly,  in  reference  to  a  pertinent  litigation  or  investigation,
including court costs, local counsel fees, deposition costs, subpoena costs, court reporter costs, expert fees,
and  other  reasonable  expenses  directly  incurred  for  investigation  or  litigation  of  claims,  incurred  by  such
Party  in  connection  with  such  action  that  have  not  previously  been  reimbursed,  and,  if  such  recovery  is
insufficient to cover all such costs and expenses of both Parties, it shall be shared in proportion to the total of
such  costs  and  expenses  incurred  by  each  Party.  Any  remaining  proceeds  in  the  Apellis  Territory  shall  be
retained  by  Apellis,  and  any  remaining  proceeds  in  the  Sobi  Territory  shall  be  retained  by  Sobi  and,
excluding  any  special,  punitive,  aggravated,  consequential  or  non-compensatory  damages  or  (without
limiting  the  first  sentence  of  this  Section  10.3.2(e)  (Enforcement  of  Technology))  any  attorneys’  fees  or
expenses, court costs, local counsel fees, deposition costs, subpoena costs, court reporter costs, expert fees,
and other reasonable expenses directly incurred for investigation or litigation or non-compensatory damages,
treated as Net Sales for purposes of royalty and Commercial Milestone Event calculations hereunder unless
otherwise agreed by the Parties.

(g)

Except  as  expressly  set  forth  in  this  Section  10.3.2  (Enforcement  of  Technology),  as  between  the  Parties,
each  Party  will  have  the  sole  right,  in  its  sole  discretion,  to  take  any  action  to  enforce  any  Intellectual
Property owned or Controlled by such Party against infringement or misappropriation by a Third Party, at
such Party’s sole cost and expense.

The Parties acknowledge that Penn reserves the right to voluntarily intervene and join in any litigation under
this  Section  10.3.2  (Enforcement  of  Technology)  relating  to  any  Intellectual  Property  licensed  under  the
Penn  Other  Fields  License  Agreement.  If  Penn  is  required  to  participate  in  any  litigation  brought  by  Sobi
under  this  Section  10.3.2  (Enforcement  of  Technology),  (such  as,  for  example,  but  not  limited  to,  being
joined or named as a defendant, necessary party, involuntary plaintiff, or indispensable party), then (i) Sobi
may seek to join Penn involuntarily and (ii) if Penn cannot be joined involuntarily, Apellis shall (at Sobi’s
request) enforce its right under section 8.3(b) of the Penn Other Fields License Agreement to join Penn in
any  litigation  referred  to  in  this  Section  10.3.2  (Enforcement  of  Technology)  if  Penn’s  participation  is
required  for  standing  to  bring  or  maintain  the  lawsuit  in  which  Sobi  seeks  to  join  Penn,  and  Sobi  shall
reimburse  Penn’s  Litigation  Expenditures  (as  defined  in  the  Penn  Other  Fields  License  Agreement)  on  an
ongoing basis, within [**] of submission of actual invoices. In any litigation brought by Penn under section
8.4 of the Penn Other Fields License Agreement, at the request and expense of Penn, Sobi shall cooperate
with  Penn  to  the  extent  reasonable  and  reasonably  possible  unless  Sobi  reasonably  deems  that  doing  so
would  present  unacceptable  business  or  legal  risks.  Sobi  shall  not  settle  or  compromise  any  litigation
enforcing any Penn Patent Rights (as defined in the Penn Other Fields License Agreement) in a manner that
imposes any obligations or restrictions on Penn without Penn’s prior written permission.

(h)

If  Penn  brings  any  litigation  to  enforce  any  Penn  Patent  Rights  pursuant  to  section  8.4  of  the  Penn  Other
Fields License Agreement, then, at the request and expense of Penn or Apellis, Sobi shall cooperate to the
extent reasonable and reasonably possible, subject to any applicable limitation set forth in section 8.5 of the
Penn Other Fields License Agreement.

10.4

Defense of Claims

.  Each Party shall promptly inform the other Party in writing if it receives written notice, or otherwise becomes aware, of a claim
of alleged infringement, misappropriation, or other violation of a Third Party’s Intellectual Property based upon either Party’s Exploitation of
any Product. Except as expressly set forth in Article 12 (Indemnification), the Party that is subject to such claim will have the right, but not
the  obligation,  to  defend  against  such  claim.   The  defending  Party  shall  keep  the  other  Party  advised  of  all  material  developments  in  the
conduct of any proceedings in defending any claim of alleged infringement, misappropriation, or other violation related to any Products, and,
at the defending Party’s request, the other Party shall reasonably cooperate with the defending Party in the conduct of such defense, and the
defending  Party  shall  reimburse  the  other  Party  for  all  reasonable  costs  and  expenses  incurred  by  the  other  Party  in  providing  such
cooperation  within  [**]  after  receipt  of  any  invoice  therefor.    In  no  event  may  the  defending  Party  settle  any  such  claim  of  infringement,
misappropriation, or other violation in a manner that would limit the rights of the other Party or impose any obligation on the other Party, in
each case, without such other Party’s prior written consent, which shall not be unreasonably withheld, delayed, or conditioned.

10.5

Patent Term Extensions

.  Apellis will have the sole right to determine and control all filings of requests for Patent Term Extensions to Products in the
Apellis Territory.  Sobi will have the sole right to determine and control all filings of requests for Patent Term Extensions to Products in the
Sobi Territory, but, other than with respect to the Patent families listed in Schedule 10.5 (Patent Term Extensions) for which Sobi shall be
free to request Patent Term Extensions without Apellis’ consent, Sobi may not request any Patent Term Extension with respect to any Apellis
Patent Right (other than the Apellis Patent Rights listed in Schedule 10.5 (Patent Term Extensions)) without Apellis’ prior written consent,
which consent Apellis may withhold in its sole discretion. Upon the reasonable request of either Party, the other Party shall provide support,
assistance,  and  all  necessary  documents,  in  fully  executed  form  if  needed,  to  such  requesting  Party  for  the  purpose  of  supporting,  filing,
obtaining,  and  maintaining  such  Patent  Term  Extensions  in  any  country  in  the  world  in  accordance  with  this  Section  10.5  (Patent  Term
Extensions),  and  the  requesting  Party  shall  reimburse  the  other  Party  for  all  reasonable  costs  and  expenses  incurred  by  the  other  Party  in
providing such support, assistance, and documents within [**] after receipt of any invoice therefor.

35 U.S.C. § 102(c)

.  Notwithstanding anything to the contrary in this Article 10 (Intellectual Property Matters), no Party will have the right to make
an  election  under  35  U.S.C.  §  102(b)(2)(C)  or  35  U.S.C.  §  102(c)  when  exercising  its  rights  under  this  Article  10  (Intellectual  Property
Matters) without the prior written consent of the other Party, which shall not be unreasonably withheld, conditioned, or delayed. With respect
to  any  such  permitted  election,  the  Parties  shall  use  reasonable  efforts  to  cooperate  and  coordinate  their  activities  with  respect  to  any
submissions, filings, or other activities in support thereof. The Parties acknowledge and agree that this Agreement is deemed a “joint research
agreement” as defined in 35 U.S.C. § 100(h).

10.7

Recording

.  If either Party deems it necessary or desirable to register or record this Agreement or provide evidence of this Agreement with
any  patent  office  or  other  appropriate  Governmental  Authority  in  one  (1)  or  more  jurisdictions  in  the  world,  then  the  other  Party  shall
reasonably  cooperate  to  execute  and  deliver  to  such  Party  any  documents  accurately  reflecting  or  evidencing  this  Agreement  that  are
necessary or desirable, in such Party’s reasonable judgment, to complete such registration or recordation.

10.8

Costs

12.3

Indemnification Procedures

.

12.3.1

Notice of Claim.  All indemnification claims in respect of any indemnitee seeking indemnification under Section 12.1
(Indemnification  by  Apellis),  Section  12.2  (Indemnification  by  Sobi),  Section  5.2.6(e)  (Assignment  of  EMA  PNH
Regulatory Approval), or Section 5.2.6(g) (Assignment of EMA PNH Regulatory Approval), as applicable (collectively,
the “Indemnitees”  and  each,  an  “Indemnitee”),  shall  be  made  solely  by  the  corresponding  Party  (the  “Indemnified
Party”).  The Indemnified Party shall give the indemnifying Party (the “Indemnifying Party”) prompt written notice
(an “Indemnification Claim Notice”) of any Third Party Claim or Losses as to which the Indemnified Party intends to
make a request for indemnification under Section 12.1 (Indemnification by Apellis),  Section 12.2 (Indemnification by
Sobi),  Section  5.2.6(e)  (Assignment  of  EMA  PNH  Regulatory  Approval),  or  Section  5.2.6(g)  (Assignment  of  EMA
PNH Regulatory Approval), as applicable. In no event will the Indemnifying Party be liable for any Losses that result
from  any  delay  in  providing  such  notice.    Each  Indemnification  Claim  Notice  shall  contain  a  description  of  the
applicable  Third  Party  Claim  and  the  nature  and  amount  of  the  applicable  Losses  (to  the  extent  that  the  nature  and
amount of such Losses are known at such time). Together with the Indemnification Claim Notice, the Indemnified Party
shall furnish promptly to the Indemnifying Party copies of all notices and documents (including court papers) received
by any Indemnitee in connection with the applicable Third Party Claim.

12.3.2

Control of Defense.  At its option, the Indemnifying Party may assume the defense of any Third Party Claim subject to
indemnification  under  Section  12.1  (Indemnification  by  Apellis),  Section  12.2  (Indemnification  by  Sobi),  Section
5.2.6(e) (Assignment of EMA PNH Regulatory Approval), or Section 5.2.6(g) (Assignment of EMA PNH Regulatory
Approval), as applicable, by giving written notice to the Indemnified Party within [**] after the Indemnifying Party’s
receipt of an Indemnification Claim Notice.  Upon assuming the defense of a Third Party Claim, the Indemnifying Party
may appoint as lead counsel in the defense of the Third Party Claim any legal counsel it selects, and such Indemnifying
Party shall thereafter continue to defend such Third Party Claim in good faith.  Should the

104

 
 
 
 
12.3.3

12.3.4

12.3.5

Indemnifying Party assume the defense of a Third Party Claim and continue to defend such Third Party Claim in good
faith, the Indemnifying Party will not be liable to the Indemnified Party or any other Indemnitee for any legal expenses
subsequently  incurred  by  such  Indemnified  Party  or  other  Indemnitee  in  connection  with  the  analysis,  defense,  or
settlement of the Third Party Claim.

Right to Participate in Defense. Without limiting Section 12.3.2 (Control of Defense), any Indemnitee will be entitled
to participate in the defense of a Third Party Claim for which it has sought indemnification hereunder and to employ
counsel  of  its  choice  for  such  purpose,  but  such  employment  will  be  at  the  Indemnitee’s  own  expense  unless  (a)  the
employment  thereof  has  been  specifically  authorized  by  the  Indemnifying  Party  in  writing,  or  (b)  the  Indemnifying
Party  has  failed  to  assume  the  defense  of,  or  failed  to  continue  to  defend  in  good  faith,  such  Third  Party  Claim  in
accordance with this Section 12.3 (Indemnification Procedures), in which case the Indemnified Party will be allowed to
control the defense at the Indemnifying Party’s cost and expense.

Settlement.  The Indemnifying Party shall not agree to any settlement of, or the entry of any judgment arising from, any
indemnification claim without the prior written consent of the Indemnified Party (such consent not to be unreasonably
withheld, delayed or conditioned); provided, however, that the consent of the Indemnified Party shall not be required
with respect to any such settlement or judgment if the Indemnifying Party or its insurer agrees in writing to pay or cause
to be paid any amounts payable pursuant to such settlement or judgment and includes a full release of the Indemnified
Party from further liability and if such settlement or judgment imposes no admission of liability by or other obligation
on  the  Indemnified  Party  that  will  not  be  assumed  and  performed  in  full  by  the  Indemnifying  Party.  Regardless  of
whether the Indemnifying Party chooses to defend or prosecute any Third Party Claim, no Indemnitee will admit any
liability  with  respect  to,  or  settle,  compromise,  or  discharge,  any  Third  Party  Claim  without  first  offering  to  the
Indemnifying Party the opportunity to assume the defense of the Third Party Claim in accordance with Section 12.3.2
(Control of Defense).

Cooperation.  If the Indemnifying Party chooses to defend or prosecute any Third Party Claim, the Indemnified Party
shall,  and  shall  cause  each  Indemnitee  to,  cooperate  in  the  defense  or  prosecution  thereof  and  furnish  such  records,
information,  and  testimony,  provide  such  witnesses,  and  attend  such  conferences,  discovery  proceedings,  hearings,
trials, and appeals as may be reasonably requested in connection with such Third Party Claim.  Such cooperation shall
include  access  during  normal  business  hours  afforded  to  the  Indemnifying  Party  to,  and  reasonable  retention  by  the
Indemnified  Party  of,  records  and  information  that  are  reasonably  relevant  to  such  Third  Party  Claim,  and  making
Indemnitees and other employees and agents available on a mutually convenient basis to provide additional information
and  explanation  of  any  such  materials.  The  Indemnifying  Party  shall  reimburse  the  Indemnified  Party  for  all  its
reasonable Out-of-Pocket Costs incurred in connection with such cooperation within [**] after receipt of any invoice
therefor.

12.4

Limitation of Liability

.  EXCEPT IN THE CASE OF FRAUD, GROSS NEGLIGENCE OR WILLFUL MISCONDUCT, NEITHER PARTY WILL BE
LIABLE  TO  THE  OTHER  FOR  ANY  SPECIAL,  CONSEQUENTIAL,  INCIDENTAL,  PUNITIVE,  OR  INDIRECT  DAMAGES
(INCLUDING LOST PROFITS OR LOSS REVENUES) ARISING FROM OR RELATING TO THIS AGREEMENT, REGARDLESS OF
ANY  NOTICE  OF  THE  POSSIBILITY  OF  SUCH  DAMAGES.    NOTWITHSTANDING  THE  FOREGOING,  NOTHING  IN  THIS
SECTION 12.4

105

 
 
 
 
 
 
(LIMITATION  OF  LIABILITY)  IS  INTENDED  TO  OR  WILL  LIMIT  OR  RESTRICT  THE  INDEMNIFICATION  RIGHTS  OR

OF SOBI) SECTION 5.2.6(e) (ASSIGNMENT OF EMA PNH REGULATORY APPROVAL), OR SECTION 5.2.6(g) (ASSIGNMENT OF
EMA  PNH  REGULATORY  APPROVAL),  OR  DAMAGES  AVAILABLE  FOR  A  PARTY’S  BREACH  OF  EXCLUSIVITY
OBLIGATIONS  UNDER  SECTION  2.6 
(EXCLUSIVITY)  OR  CONFIDENTIALITY  OBLIGATIONS  UNDER  Article  13
(CONFIDENTIALITY).

Insurance

.  

12.5.1

cover its obligations hereunder and consistent with normal business practices of prudent companies similarly situated at
all times during which the Products are being clinically tested in human subjects or commercially distributed or sold by
such Party pursuant to this Agreement, and the insurance coverage shall in no event be less than (a) prior to the First
Commercial Sale of a Product in any country, $[**] per loss occurrence and $[**] in the aggregate, and (b) after the
First Commercial Sale in any country, $[**] per loss occurrence and $[**] in the aggregate. It is understood that such
insurance will not be construed to create a limit of either Party’s liability with respect to its indemnification obligations
under  this  Article  12  (Indemnification).    Each  Party  shall  provide  the  other  Party  with  written  evidence  of  such
insurance  upon  request.  Notwithstanding  anything  to  the  contrary  herein,  Apellis  expressly  reserves  the  right  to  self-
insure.

transactions  set  forth  in  this  Agreement,  and  including  any  “Confidential  Information”  disclosed  by  either  Party  pursuant  to  the  Existing
CDA), but Confidential Information will not include any information or materials that:

13.1.1

13.1.2

Affiliates  or  any  Third  Party  to  whom  the  Receiving  Party  or  any  of  its  Affiliates  provided  such  information  or
materials;

13.1.4

13.1.5

and had no obligation to the Disclosing Party not to disclose such information or materials to others; or

were independently discovered or developed by or on behalf of the Receiving Party without the use of or reference to
any  Confidential  Information  belonging  to  the  Disclosing  Party,  to  the  extent  such  Receiving  Party  has  documentary
evidence to that effect.

Each Party and its Affiliates shall protect the confidential Collaboration Know-How using the same degree of care and
in  accordance  with  the  same  internal  processes  and  safeguards  with  which  it  maintains  the  confidentiality  of  its  own
Confidential Information, but in all cases no less than a reasonable degree of care.

13.4

Confidentiality Obligations

.   The Receiving Party shall keep confidential all of the Disclosing Party’s Confidential Information using the same degree of care

Information, but in all cases no less than a reasonable degree of care.  The Receiving Party may disclose the Disclosing Party’s Confidential
Information:

terms  at  least  as  protective  as  those  contained  in  this  Article  13  (Confidentiality))  that  all  such  directors,  managers,
employees, independent contractors, agents, and consultants comply with such obligations;

each  case  pursuant  to  customary  confidentiality  agreements  containing  terms  no  less  protective  of  the  Confidential
Information than are those set forth in this Article 13 (Confidentiality); or

any Product, as long as such press releases are made in accordance with the Receiving Party’s standard practices with
respect to such press releases and, unless such Party reasonably determines that such inclusion is required by Applicable

Party shall, to the extent such Party reasonably determines that it is in compliance with Applicable Law and applicable
regulations of, agreement with, and rules of a national securities exchange, provide a copy of such press release to the
other Party for such other Party’s review at least [**] prior to the issuance of such press release and consider in good

maintain  the  confidentiality  of  all  provisions  of  this  Agreement,  and,  without  the  prior  written  consent  of  the  other
Party,  neither  Party  nor  any  of  either  Party’s  respective  Affiliates  shall  make  any  press  release  or  other  public
announcement regarding this Agreement, or otherwise disclose the provisions of this Agreement to any Third Party.

Notwithstanding  Section  13.6.1  (Publicity;  Filing  of  this  Agreement),  each  Party  may  summarize  or  disclose  the
provisions of this Agreement, as reasonably necessary:

(a)

(b)

(c)

(d)

(e)

to  those  of  its  directors,  officers,  employees,  accountants,  attorneys,  underwriters,  lenders  and  other
financing  sources,  advisors,  and  agents  whose  duties  reasonably  require  them  to  have  access  to  such
provisions, as long as such directors, officers, employees, accountants, attorneys, underwriters, lenders and
other financing sources, advisors, and agents are required to maintain the confidentiality of such provisions;

as  required  by  the  NASDAQ  regulations  or  any  listing  agreement  with  or  rules  of  a  national  securities
exchange, in which case the disclosing Party shall provide the non-disclosing Party with at least [**] notice
unless  otherwise  not  practicable  or  permissible  under  Applicable  Law  or  under  applicable  regulations  of,
agreement with, or rules of a national securities exchange, but in any event no later than the time that the
disclosure required by such NASDAQ regulations or listing agreement is made, but to the extent permitted
by Applicable Law and applicable regulations of, agreement with, or rules of a national securities exchange,
the disclosing Party shall use reasonable efforts to ensure confidential treatment of such information;

as may be required by Applicable Law (including any rule or regulation promulgated by the U.S. Securities
and Exchange Commission), in which case the disclosing Party shall, to the extent permitted by Applicable
Law  and  applicable  regulations  of,  agreement  with,  or  rules  of  a  national  securities  exchange,  provide  the
non-disclosing Party with prompt advance notice of such disclosure and cooperate with the non-disclosing
Party to seek a protective order or other appropriate remedy, including a request for confidential treatment in
the case of a filing with the Securities and Exchange Commission;

by filing the press release set forth on Schedule 13.6 (Press Release), or by filing a report on Form 8-K along

as required under the terms of the Existing Agreements or Collaboration In-Licenses, in each case pursuant
to customary confidentiality agreements

109

 
 
 
 
 
 
 
 
 
containing terms no less protective of the Confidential Information than are those set forth in this Article 13
(Confidentiality); or

(f)

as has been previously permitted by the other Party.  

A Party may publicly disclose, without regard to the preceding requirements of this Section 13.6 (Publicity;
Filing of this Agreement), any information that was previously publicly disclosed pursuant to this Section

Product, or any Exploitation thereof (other than any publication or presentation that relates to any Non-Systemic Ophthalmology Product, but
does not specifically relate any Product) (each, a “Publication”). Neither Party may publish any Publication except in accordance with the
Publication Plan. For the avoidance of doubt, nothing in this Section 13.7 (Publication) limits Apellis’ right to publish any publication or
presentation that relates to any Non-Systemic Ophthalmology Product and does not specifically relate to any Product.

Party  in  relation  to  this  transaction  in  any  public  announcement,  press  release,  or  other  public  document  without  the
written consent of such other Party, which consent will not be unreasonably withheld; except that,  subject  to  Section
13.6 (Publicity; Filing of this Agreement), either Party may use the name of the other Party in any document required to
be filed with any Governmental Authority, including the Securities and Exchange Commission.

Use  of  Penn’s  Name.  Except  as  otherwise  set  forth  in  this  Agreement  or  as  required  under  Applicable  Law  or

Sublicensees,  Subcontractors,  employees,  and  agents  may  not  use  the  name,  logo,  seal,  trademark,  or  service  mark
(including  any  adaptation  of  them)  of  Penn  or  any  Penn  school,  organization,  employee,  student  or  representative,
without  the  prior  written  consent  of  Penn.  For  clarity,  notwithstanding  the  foregoing,  Sobi  and  its  Affiliates,
Sublicensees,  Subcontractors,  vendors,  and  manufacturers  shall  have  the  right  to  mark  the  Products  and  packaging
thereof with relevant patent numbers

13.9

Survival

.   The  obligations  and  prohibitions  contained  in  this  Article  13  (Confidentiality)  as  they  apply  to  Confidential  Information  will

survive any expiration or termination of this Agreement for a period of [**].

14.1

Term

ARTICLE 14

TERM AND TERMINATION

.  This Agreement will become effective on the Effective Date and, unless earlier terminated pursuant to this Article 14 (Term and

Termination), will remain in effect until it expires (a) on a

110

 
 
 
 
 
 
Product-by-Product and country-by-country basis, upon the expiration of the Royalty Term for such Product in such country and (b) in its
entirety, upon the expiration of all Royalty Terms for all Products in all countries in the Sobi Territory (the “Term”).

14.2

Termination for Breach

.

14.2.1

Breach  by  Apellis.    In  the  event  of  a  material  breach  of  this  Agreement  by  Apellis,  which  material  breach  remains
uncured  for  [**]  measured  from  the  date  of  Apellis’  receipt  of  written  notice  of  such  material  breach  from  Sobi  that
identifies  the  material  breach  in  reasonable  detail,  without  prejudice  to  Section  17.6  (Remedies),  Sobi  may  either  (a)
terminate  this  Agreement  in  its  entirety  by  written  notice  of  termination  to  Apellis  or  (b)  elect  to  continue  this
Agreement, initiate arbitration against Apellis for damages and offset from Sobi’s payment obligations hereunder one
hundred percent (100%) of all damages assessed in accordance with Section 16.5 (Arbitration).  

14.2.2

Breach by Sobi.  

(a)

(b)

In the event of a material breach of this Agreement by Sobi, which material breach remains uncured for [**]
(or,  subject  to  Section  9.8  (Late  Payments),  [**]  in  the  case  of  Sobi’s  payment  obligations  under  this
Agreement) measured from the date of Sobi’s receipt of written notice of such material breach from Apellis
that identifies the material breach in reasonable detail, without prejudice to Section 17.6 (Remedies), Apellis
may terminate this Agreement in its entirety by written notice of termination to Sobi, but, if such breach is
not susceptible of cure within such [**] cure period even with the use of Commercially Reasonable Efforts,
Apellis’ right to terminate shall be suspended if and for so long as Sobi has provided to Apellis a reasonable
written  plan,  calculated  to  effect  a  cure  of  such  breach,  and  commits  to  and  is  diligently  performing  such
plan.

In the event of a material breach by Sobi of Section 4.3 (Development Diligence Obligations) or Section 6.2
(Commercialization  Diligence  Obligations)  with  respect  to  Sobi’s  obligation  to  use  Commercially
Reasonable Efforts to Develop, obtain Regulatory Approval for, and Commercialize a Product for PNH and
ALS in any of China, Japan, Brazil, or Canada, which remains uncured for [**] measured from the date of
Sobi’s  receipt  of  written  notice  of  such  material  breach  from  Apellis  that  identifies  the  material  breach  in
reasonable detail, without prejudice to Section 17.6 (Remedies), Apellis may terminate this Agreement with
respect to such country by written notice of termination to Sobi, but, if such breach is not susceptible of cure
within  such  [**]  cure  period  even  with  the  use  of  Commercially  Reasonable  Efforts,  Apellis’  right  to
terminate shall  be  suspended  if  and  for  so  long  as  Sobi  has  provided  to  Apellis  a  reasonable  written  plan,
calculated  to  effect  a  cure  of  such  breach,  and  commits  to  and  is  diligently  performing  such  plan.  When
determining  the  timing  and  order  of  Commercial  launch  of  a  given  Product  and  Indication  in  each  Major
Market,  Sobi  may  reasonably  take  into  account  reference  pricing  strategy,  and,  when  Sobi  determines  the
timing and order of Development activities and the level of efforts to obtain Regulatory Approval for such
Product,  Sobi  may  take  into  account  current  status  of  Development  activities  in  other  countries,  status  of
Regulatory  Approval  with  EMA,  FDA,  and  other  Regulatory  Authorities,  requirements  for  local
Manufacturing in the applicable country(ies), competitiveness of Third Party products, patent and regulatory
exclusivity, anticipated or approved labelling,

111

 
 
 
 
 
 
present  and  future  market  potential,  competitive  market  conditions  and  the  profitability  of  the  Product  in
light of pricing and reimbursement issues, reference Regulatory Approval strategy and reference pricing and
reimbursement strategy.

14.3

Termination for Patent Challenge

.  If (a) Sobi or any of its Affiliates challenges the validity, scope, or enforceability of, or otherwise opposes, any Apellis Patent Right in any
action or proceeding, other than as may be necessary or reasonably required to assert a defense, cross-claim, or counter-claim in an action or
proceeding asserted by Apellis or any of its Affiliates or other sub/licensees or the counterparty to an Upstream Agreement or their licensees
or assignees against Sobi or any of its Affiliates or Sublicensees, or to respond to a court request or order or administrative agency request or
order, (each such challenge, a “Challenge”)  or  (b)  any  of  Sobi’s  Sublicensees  participates  in  a  Challenge  and  Sobi  does  not  terminate  its
sublicense with such Sublicensee upon written notice from Apellis, Apellis shall have the right to terminate this Agreement upon [**] written
notice unless Sobi or its applicable Affiliate or Sublicensee has filed a motion to dismiss with prejudice such action or caused such action to
be dismissed with prejudice within [**] following receipt of such notice. Notwithstanding the foregoing, none of the following activities shall
be a Challenge and Apellis shall not have a right to terminate this Agreement under this Section 14.3 (Termination for Patent Challenge) with
respect to: (a) any actions undertaken by an Affiliate of Sobi that first becomes such an Affiliate as a result of an acquisition of all or any part
of Sobi or any of its Affiliates, where such new Affiliate was participating in the Challenge prior to such acquisition; (b) situations where
Sobi or its Affiliate or Sublicensee is to participate in a challenge to the validity, scope, or enforceability of, or otherwise oppose, any Apellis
Patent Right pursuant to a subpoena or court order or participates in a proceeding that is initiated by a patent office and not at the instigation
of Sobi or any of its Affiliates or Sublicensees.  For clarity, this Section 14.3 (Termination for Patent Challenge) shall not apply to arguments
made by Sobi or its Affiliates or Sublicensees that distinguish the inventions claimed in an Apellis Patent Right from those claimed in the
patent applications owned or controlled by Sobi or any of its Affiliates or Sublicensees in the ordinary course of ex parte prosecution of such
patent applications.

14.4

Termination for Insolvency

.    To  the  extent  permitted  by  Applicable  Law,  either  Party  may  terminate  this  Agreement  upon  the  filing  or  institution  of
bankruptcy, reorganization, liquidation, or receivership proceedings, upon the appointment of a receiver or trustee over all or substantially all
property, or upon an assignment of a substantial portion of the assets for the benefit of creditors by the other Party; except that, in the case of
any  involuntary  bankruptcy  proceeding,  such  right  to  terminate  will  only  become  effective  if  such  other  Party  consents  to  the  involuntary
bankruptcy or such proceeding is not dismissed within [**] after the filing thereof.

14.5

Termination by Sobi for Convenience

.  At any time after the earlier of (a) the second anniversary of the Effective Date or (b) receipt of the first Regulatory Approval for
the first Product in any Major European Country, Sobi may terminate this Agreement in its entirety, at its sole discretion and for any or no
reason, upon ninety (90) days’ prior written notice to Apellis.

15.1

Effects of Expiration

ARTICLE 15

EFFECTS OF EXPIRY AND TERMINATION

.  Upon any expiration (but not earlier termination) of this Agreement, each Receiving Party shall return or destroy all documents,
tapes, and other media containing Confidential Information of the Disclosing Party that remain in the possession of the Receiving Party or
any  of  its  directors,  managers,  employees,  independent  contractors,  agents,  or  consultants;  except that  (a)  nothing  herein  will  require  the
destruction or deletion of back-up media made in the ordinary course of business and not accessible in the ordinary course of business, as
long as the

112

 
 
 
Receiving Party does not access, and ensures that no other Person may access, any of the Disclosing Party’s Confidential Information on any
such  back-up  media;  (b)  the  Receiving  Party  may  keep  one  (1)  copy  of  the  Disclosing  Party’s  Confidential  Information  in  the  legal
department  files  of  the  Receiving  Party,  solely  for  archival  purposes,  but  such  archival  copy  will  be  deemed  to  be  the  property  of  the
Disclosing Party, and will continue to be subject to the provisions of Article 13 (Confidentiality) indefinitely and (c) Sobi shall not be obliged
to return or destroy any documents, tapes, and other media containing Apellis Know-How or Collaboration Know-How and Apellis shall not
be obligated to return or destroy any documents, tapes and other media containing Collaboration Know-How.

15.2

Effects of Termination.

    Upon  any  termination  of  this  Agreement,  in  its  entirety  or  with  respect  to  any  given  country(ies),  in  addition  to,  and  without
affecting, any other rights or remedies that the terminating Party may have, whether under statute, common law, or otherwise, the following
provisions shall take effect, either with respect to all countries in the world (in the event of a termination of this Agreement in its entirety) or
with respect to the terminated country(ies) (in the event of a termination of this Agreement with respect to one (1) or more country(ies)) (the
“Terminated Territory”):

15.2.1

Licenses. All licenses granted by Apellis to Sobi under this Agreement in the Terminated Territory shall terminate in
their entirety.  

15.2.2

Reversion License.

(a)

Sobi  (i)  hereby  grants  to  Apellis,  effective  upon  the  termination  of  this  Agreement  in  the  Terminated
Territory, an exclusive, freely sublicensable (through multiple tiers), royalty-bearing (solely as set forth in as
set forth below in this Section 15.2.2(a) (Reversion License)), perpetual, irrevocable license under the Sobi
Technology and (ii) shall, at Apellis’ written request, negotiate with Apellis in good faith a non-exclusive,
freely  sublicensable  (through  multiple  tiers),  royalty-bearing  license  under  any  Sobi  Intellectual  Property
(other than the Sobi Technology) that is necessary or useful to Exploit Products (as such Products exist as of
the  effective  date  of  termination)  in  the  Terminated  Territory  (all  Sobi  Technology  and  other  Intellectual
Property  licensed  under  clauses  (i)  and  (if  applicable)  (ii),  collectively,  the  “Reversion  Technology”)  to
Exploit  the  Products  in  the  Terminated  Territory.  If  Apellis  elects  in  writing  to  obtain  a  royalty-bearing
license as described in clause (ii) above, the Parties will discuss in good faith via their respective Executive
Officers to agree on the extent of such license and an equitable royalty payable by Apellis to Sobi to reflect
the value of the applicable Sobi Intellectual Property upon the effective date of such termination.  Solely in
the event that, following a Change of Control of Apellis, this Agreement is terminated by Sobi for Apellis’ or
its  successor’s  material  breach  of  this  Agreement  pursuant  to  Section  14.2.1  (Breach  by  Apellis),  then
Apellis’ license to the Sobi Technology under Section 15.2.2(a)(i) (Reversion License) shall bear a royalty of
[**]  percent  ([**]%)  of  “Net  Sales,”  as  defined  in  this  Agreement,  mutatis  mutandis,  in  the  Terminated
Territory  in  a  manner  analogous  to  that  set  forth  in  Section  9.5  (Royalty  Payments)  (except  that  Section
9.5.3(b) (Royalty Reduction) and Section 9.5.4 (Expiration of Royalty Term) shall not apply) and Sections
9.7 (Taxes and Withholding) through 9.12 (Financial Audits), mutatis mutandis, with the term of such royalty
for the Products in each country being ten (10) years from the later of (a) the effective date of termination
and (b) the date of First Commercial Sale of the first Product in such country. For clarity, any Sobi

113

 
 
 
 
 
Technology or other Intellectual Property resulting from Sobi’s Unilateral Development Activities shall only
be included in the Reversion Technology if Apellis opts to obtain rights therefore in accordance with Section
4.4.4(b)(iii) (Buy-In).

(b)

(c)

APELLIS  AGREES  AND  ACKNOWLEDGES  THAT  THE  LICENSE  OF  THE  REVERSION
TECHNOLOGY  UNDER  THIS  SECTION  15.2.2  (REVERSION  LICENSE)  AND  APELLIS’  AND  ITS
AFFILIATES’ AND ITS AND THEIR SUBLICENSEES’ USE OF THE REVERSION TECHNOLOGY IS
PROVIDED  ON  AN  “AS-IS”  BASIS  AND  THAT  ALL  WARRANTIES,  REPRESENTATIONS  AND
CONDITIONS WHETHER ORAL, WRITTEN, EXPRESS OR IMPLIED BY STATUTE, COMMON LAW
OR  OTHERWISE  (INCLUDING,  WITHOUT  LIMITATION,  ANY  IMPLIED  WARRANTIES  OF
QUALITY,  FITNESS  FOR  PURPOSE,  VALIDITY  OF  ANY  PATENTS  OR  NON-INFRINGEMENT  OF
ANY  INTELLECTUAL  PROPERTY  RIGHTS)  ARE  EXPRESSLY  EXCLUDED  AND  SPECIFICALLY
DISCLAIMED, TO THE EXTENT PERMITTED BY APPLICABLE LAW.

Apellis  shall  pay  Sobi  for  Apellis’  pro  rata  share  of  any  in-licensor  payments  associated  with  Apellis’
Exploitation  of  any  Product  or  Non-Systemic  Ophthalmology  Product  pursuant  to  any  sublicense  under
Sobi’s upstream licenses included in the Reversion Technology.

15.2.3

15.2.4

15.2.5

15.2.6

15.2.7

Development  Costs.  Sobi  shall  pay  its  pro  rata  share  of  Development  Costs  it  committed  to  prior  to  notice  of
termination  until  the  earlier  of  (a)  [**]  following  the  effective  date  of  termination  and  (b)  wind-down  or  transfer  to
Apellis of the relevant activity for which the Development Costs were incurred.

Report.  Within  [**]  after  such  termination,  Sobi  shall  provide  to  Apellis  a  fair  and  accurate  summary  report  of  the
status of the Development, Commercialization, Medical Affairs, and Manufacturing activities conducted by Sobi with
respect to the Products in the Terminated Territory.

Trademarks. Sobi shall transfer and assign to Apellis all rights, title, and interests in and to the Product Trademarks in
the Terminated Territory.

Regulatory Affairs. Sobi shall, as soon as reasonably practicable, transfer and assign to Apellis all Regulatory Data,
Regulatory  Submissions,  Reimbursement  Submissions,  Regulatory  Approvals,  and  Reimbursement  Approvals  with

Submissions, Reimbursement Submissions, Regulatory Approvals, and Reimbursement Approvals for its records.

Ongoing  Clinical  Trials.  Solely  in  the  event  of  a  termination  of  this  Agreement  in  its  entirety,  with  respect  to  each
Clinical  Trial  for  any  Product  that  is  ongoing  on  the  effective  date  of  termination,  the  Parties  shall  (to  the  extent
applicable) use Commercially Reasonable Efforts to transition full responsibility for, and control of, such Clinical Trial
to  Apellis,  and  Sobi  shall  remain  responsible  for  its  applicable  share  of  all  cost  and  expenses  (including  any  Shared
Development Costs) with respect to such Clinical Trial until full responsibility for, and control of, such Clinical Trial
has been transitioned to Apellis.

Inventory.

(a)

(b)

(c)

Without limiting Sobi’s obligations under Section 15.2.6 (Regulatory Affairs), in the event of a termination
of this Agreement in its entirety, or with respect to any given country(ies),  Sobi will have the right, but not
the obligation, for [**] following the effective date of such termination to sell any remaining inventory of
Product for the Terminated Territory then owned by and in the possession of Sobi or its Affiliates, as long as
Sobi  continues  to  make  milestone  and  royalty  payments  under  Article  9  (Payments)  in  respect  of  the  Net
Sales resulting from sales of such inventory.

Following the [**] period specified in Section 15.2.8(a) (Inventory), or at Sobi’s request, solely in the event
of  a  termination  of  this  Agreement  in  its  entirety,  Apellis  shall  have  the  option,  exercisable  within  [**]
following  the  effective  date  of  termination,  to  obtain  inventory  of  the  Products  then  owned  by  and  in  the
possession of Sobi or its Affiliates at a price equal to, as applicable, the amount Sobi paid Apellis for such
inventory or Sobi’s Manufacturing Costs for such inventory. If Apellis exercises the option set forth in the
preceding sentence, then Sobi shall grant, and hereby does grant, effective on the exercise of such option, a
royalty-free right and license to use any trademarks, names, and logos of Sobi appearing on such inventory
of the applicable Products for a period of [**] solely to permit the orderly sale of such inventory, subject to
Apellis meeting reasonable quality control standards imposed by Sobi on the use of such trademarks, names,
and logos, which will be consistent with the standards used by Sobi prior to such termination.

APELLIS  AGREES  AND  ACKNOWLEDGES  THAT  ANY  INVENTORY  ACQUIRED  UNDER
SECTION  15.2.8(b)  (INVENTORY)  IS  PROVIDED  ON  AN  “AS-IS”  BASIS  AND  THAT  ALL
WARRANTIES, REPRESENTATIONS, AND CONDITIONS, WHETHER ORAL, WRITTEN, EXPRESS,
OR  IMPLIED  BY  STATUTE,  COMMON  LAW,  OR  OTHERWISE  (INCLUDING  ANY  IMPLIED
WARRANTIES  OF  QUALITY  OR  FITNESS  FOR  PURPOSE  OR  NON-INFRINGEMENT  OF  ANY
INTELLECTUAL  PROPERTY  RIGHTS)  ARE  EXPRESSLY  EXCLUDED  AND  SPECIFICALLY
DISCLAIMED, TO THE EXTENT PERMITTED BY APPLICABLE LAW.

15.2.9 Manufacturing.  Solely in the event of a termination of this Agreement in its entirety, to the extent that Sobi was using
a  Third  Party  manufacturer  to  Manufacture  any  Compounds  or  Products  immediately  prior  to  such  termination,  at
Apellis’  written  request,  to  the  extent  permitted  by  the  terms  of  any  applicable  contract  with  such  Third  Party
manufacturer  and  to  the  extent  such  contract  exclusively  relates  to  the  Compounds  or  Products,  Sobi  shall  use
Commercially Reasonable Efforts to assign to Apellis the manufacturing agreements with such Third Party with respect
to the Compounds and Products.

15.2.10

Prosecution.  Sobi  shall,  if  applicable,  provide  reasonable  assistance  to  Apellis  and  reasonable  cooperation  in
connection with the transition of Prosecution, defense, and enforcement responsibilities to Apellis with respect to the
Apellis Technology (for the avoidance of doubt, including any Joint Technology) then being Prosecuted, defended, or
enforced by Sobi in the Terminated Territory, including execution of such documents as may be reasonable necessary to
effect such transition.

115

 
 
 
 
 
 
 
 
15.2.11

Post-Termination Confidentiality Obligations. Solely in the event of a termination of this Agreement in its entirety,
Sobi  shall  return  or  destroy  all  documents,  tapes,  or  other  media  containing  Confidential  Information  of  Apellis  that
remain in the possession of Sobi or its directors, managers, employees, independent contractors, agents, or consultants;
except that (a) nothing herein will require the destruction or deletion of back-up media made in the ordinary course of
business and not accessible in the ordinary course of business, as long as Sobi does not access, and ensures that no other
Person may access, any of Apellis’ Confidential Information on any such back-up media and (b) Sobi may keep one (1)
copy  of  Apellis’  Confidential  Information  in  Sobi’s  legal  department  files,  solely  for  archival  purposes,  but  such
archival copy will be deemed to be the property of Apellis, and will continue to be subject to the provisions of Article
13 (Confidentiality) indefinitely.

15.2.12 Upstream Payments. Notwithstanding anything to the contrary in this Agreement, Apellis shall be solely responsible
for any payments that become owed under any Upstream Agreement with respect to the Exploitation of any Product in
the Terminated Territory following the applicable termination and shall be responsible for complying with all terms of
the  Upstream  Agreements  related  to  such  Exploitation  of  Products  in  the  Terminated  Territory  following  such
termination.

15.3

Committees

. Upon termination or expiration of this Agreement for any reason, all Committees shall be immediately dissolved.

15.4

Transition.

    Upon  termination  or  expiration  of  this  Agreement  for  any  reason,  the  Parties  will  cooperate  in  good  faith  to  effect  a  smooth

transition of any Development or Commercialization activities as soon as reasonably practicable.

15.5

Accrued Rights

.  Termination or expiration of this Agreement for any reason will be without prejudice to any rights that will have accrued to the
benefit of a Party prior to the effective date of such termination or expiration.  Termination or expiration of this Agreement for any reason
will not relieve a Party from obligations that are expressly indicated to survive the termination or expiration of this Agreement.

15.6

Sublicenses

.  Upon the termination of this Agreement pursuant to Section 14.2 (Termination for Breach), Section 14.3 (Termination for Patent
Challenge),  or  Section  14.4  (Termination  for  Insolvency),  at  each  Sublicensee’s  request,  Apellis  shall  grant  to  such  Sublicensee  a  direct
license on the terms set forth in this Agreement, provided that (a) such Sublicensee is not then in default of its sublicense agreement and not
the cause of Licensee’s material breach hereunder, (b) such terms shall include an obligation to pay royalties at a rate which is the greater of
the  royalty  rate  set  forth  in  this  Agreement  and  that  set  forth  in  the  relevant  sublicense,  and  any  country-specific  regulatory  milestones
applicable to such sublicense calculated in the same manner as set forth in Section 9.3 (Development Milestones) of this Agreement, and (c)
unless otherwise agreed by Apellis, the terms of such direct license shall not require Apellis to undertake any obligations to the Sublicensee
beyond the grant of the direct license. For clarity, nothing in this Section 15.6 (Sublicenses) shall be interpreted as requiring the survival of
any of Sobi’s obligations under this Agreement following termination, which shall be governed solely by Section 15.7 (Survival).

15.7

Governing Law

ARTICLE 16

DISPUTE RESOLUTION

.  This Agreement, and all claims arising under or in connection therewith, will be governed by and interpreted in accordance with

the substantive laws of the State of New York, without regard to conflict of law principles thereof.

16.2

Disputes

.  Except as otherwise expressly set forth in this Agreement, disputes of any nature arising under, relating to, or in connection with
this Agreement (except for disputes arising at or referred to the JEC pursuant to Article 3 (Governance), which will be resolved in accordance
with Section 3.7 (Decisions of the Committees)) will be resolved pursuant to this Article 16 (Dispute Resolution).

16.3

Resolution by Executive Officers

.  With respect to all disputes, claims, or controversies arising out of or in connection with this Agreement that do not involve a
failure to reach agreement on a matter reserved for decision by a Committee while the Committees remain in existence, including any alleged
failure to perform under, or breach of, this Agreement, or any issue relating to the formation, existence, validity, enforceability, performance,
interpretation, breach, termination, or application of this Agreement (“Disputes”),  if  the  Parties  are  unable  to  resolve  such  Dispute  within
[**]  after  such  Dispute  is  first  identified  by  either  Party  in  writing  to  the  other,  then  the  Parties  will  refer  such  Dispute  to  the  Executive
Officers of each Party.  The Executive Officers of both Parties will meet to attempt to resolve such Dispute.  Such resolution, if any, of a
referred issue will be final and binding on the Parties. All negotiations pursuant to this Article 16 (Dispute Resolution) are confidential and
will  be  treated  as  compromise  and  settlement  negotiations  for  purposes  of  applicable  rules  of  evidence.  If  the  Executive  Officers  cannot
resolve such Dispute within [**] after either Party requests such a resolution in writing, then such Dispute shall be resolved as set forth in
Section 16.5 (Arbitration).

16.4

Neutral Safety Committee

.  If the JEC does not approve an Additional Development Proposal because one Party has a reasonable, good faith concern that
the proposed Additional Global Development Activities raise material safety or scientific concerns, then, at the Proposing Party’s request, the
Parties agree to submit such matter to a committee of three (3) Qualified Safety Experts (each and every such committee of three Qualified
Safety Experts, a “Neutral Safety Committee”) appointed as provided in this Section 16.4 (Neutral Safety Committee) to determine whether
the proposed Additional Development Activities raise material safety or scientific concerns for the Development or Commercialization of
any Product. Within [**] following any such request for a Neutral Safety Committee, each of Sobi and Apellis shall nominate a Qualified
Safety Expert to participate on the applicable Neutral Safety Committee and, if the Parties are unable to agree upon a third Qualified Safety
Expert for such Neutral Safety Committee within [**] following such

117

 
 
request for a Neutral Safety Committee, then the initial two (2) Qualified Safety Experts shall select such third Qualified Safety Expert. Each
Neutral Safety Committee shall act as follows: (a) each Qualified Safety Expert (and the Neutral Safety Committee as a whole) shall act as an
expert and not as an arbitrator; (b) each decision of the Neutral Safety Committee shall be by majority vote of the three (3) Qualified Safety
Experts; and (c) the decision of the Neutral Safety Committee is, in the absence of fraud or manifest error, final and binding on the Parties.
The  costs  and  expenses  of  any  Neutral  Safety  Committee  shall  be  shared  fifty  percent  (50%)/fifty  percent  (50%)  by  the  Parties,  and  each
Party shall pay its share of such costs and expenses within [**] after receipt of any invoice therefor.

16.5

Arbitration

.  Subject to Section 16.5.1 (Baseball Arbitration) and Section 16.5.2 (Intellectual Property Disputes), all Disputes arising out of or
in connection with this Agreement that are not resolved in accordance with Article 3 (Governance), Section 16.3 (Resolution by Executive
Officers),  or  Section  16.4  (Neutral  Safety  Committee)  and  are  not  subject  to  a  Party’s  final  decision-making  authority  in  accordance  with
Article 3 (Governance) shall be finally settled under the Rules of Arbitration of the International Chamber of Commerce (the “Rules”) by
three arbitrators appointed in accordance with said Rules.  The language of the arbitration shall be English.  The place of arbitration shall be
New York, New York.  The arbitrators shall award to the prevailing party, if any, as determined by the arbitrator(s) its reasonable attorneys’
fees and costs.  Judgment on an award may be entered in any court having jurisdiction thereof.  The parties shall maintain the confidential
nature  of  the  arbitration  proceeding  and  the  Award,  including  the  hearing,  except  as  may  be  necessary  to  prepare  for  or  conduct  the
arbitration hearing on the merits, or except as may be necessary in connection with a court application for a preliminary remedy, a judicial
challenge to an award or its enforcement, or unless otherwise required by law or judicial decision.

16.5.1

Baseball Arbitration.

  In respect of a matter that requires resolution via baseball arbitration the following additional procedure shall apply:

(a)

(b)

(c)

Within [**] after the appointment of the arbitrators, each Party will provide the arbitrators with a proposal
and  written  memorandum  in  support  of  its  position  regarding  the  Dispute,  as  well  as  any  documentary
evidence it wishes to provide in support thereof (not to exceed [**]) (each a “Proposal”) and the arbitrators
will provide each Party’s Proposal to the other Party after it receives it from both Parties.

Within  [**]  after  a  Party  submits  its  Proposal,  the  other  Party  will  have  the  right  to  submit  a  rebuttal
memorandum  (not  to  exceed  [**]),  if  any,  to  the  arbitrators  and  the  other  Party.  If  requested  by  the
arbitrators, the Parties will make oral submissions to the arbitrators based on such Party’s Proposal.  

Within [**] after the receipt by the arbitrators of both Parties’ written submissions (or expiration of the [**]
period if any Party fails to submit a response), the arbitrators will issue a final award in writing, stating their
reasoning,  provided  that  the  arbitrators  will  select  one  of  the  Parties’  Proposals.  The  decision  of  the
arbitrators  will  be  the  sole,  exclusive,  binding  and  non-appealable  remedy  between  them  regarding  the
dispute referred to baseball arbitration.

16.5.2

Intellectual Property Disputes.

  Unless otherwise agreed by the Parties, a dispute between the Parties relating to the validity or enforceability of any Patent Right
shall not be subject to arbitration, but shall instead be submitted to a court or patent office of competent jurisdiction in the relevant country or
jurisdiction in which such Patent Right was issued

118

 
 
 
 
 
 
 
or,  if  not  issued,  in  which  the  underlying  patent  application  was  filed,  and  any  dispute  between  the  Parties  relating  to  the  ownership  or
inventorship  of  any  Patent  Right  shall  not  be  subject  to  arbitration,  but  shall  instead  be  submitted  to  a  federal  district  court  of  competent
jurisdiction located in New York, New York.

16.6

Equitable Remedies

.    Notwithstanding  any  provision  to  the  contrary  set  forth  in  this  Agreement,  the  Parties  each  stipulate  and  agree  that  (a)  any
breach of this Agreement will cause irrevocable harm for which monetary damages would not provide a sufficient remedy; and (b) in such
case  of  such  breach  of  this  Agreement,  the  non-breaching  Party  will  be  entitled  to  equitable  relief,  including,  as  applicable,  specific
performance, temporary or permanent restraining orders, preliminary injunction, permanent injunction, or other equitable relief, without the
posting of any bond or other security, from the arbitrators or any court of competent jurisdiction.

17.1

Assignment

ARTICLE 17
MISCELLANEOUS

.    Neither  this  Agreement  nor  any  interest  hereunder  will  be  assignable  or  delegable  by  either  Party  without  the  prior  written
consent  of  the  other  Party,  except  as  follows:  (a)  a  Party  may,  subject  to  the  terms  of  this  Agreement,  assign  its  rights  and  delegate  its
obligations under this Agreement in whole to its successor-in-interest in connection with the sale of all or substantially all of its assets to
which this Agreement specifically relates, whether in a merger, acquisition, or similar transaction or series of related transactions, as long as
(i) such sale is not primarily for the benefit of its creditors and (ii) such successor-in-interest agrees in writing to be bound by the terms and
conditions of this Agreement; and (b) a Party may assign its rights and delegate its obligations under this Agreement to any of its Affiliates,
as long as, in each case ((a) and (b)), such assigning Party remains liable for all of its rights and obligations under this Agreement.  This
Agreement will be binding upon the successors and permitted assigns of the Parties and the name of a Party appearing herein will be deemed
to include the names of such Party’s successors and permitted assigns to the extent necessary to carry out the intent of this Agreement.  Any
assignment not in accordance with this Section 17.1 (Assignment) will be null, void, and of no legal effect.

17.2

Entire Agreement; Amendment

.    This  Agreement  and  the  DTPA  do,  and,  when  negotiated  and  entered  into,  the  SDEA,  Supply  Agreement,  and  Quality
Agreement  will,  collectively,  set  forth    the  entire  agreement  between  the  Parties,  and  supersede  all  previous  and  contemporaneous
negotiations, representations, or agreements, written or oral, regarding the subject matter hereof and thereof. Any other express or implied
agreements, understandings, negotiations, writings, or commitments, either oral or written, with respect to the subjects and licenses hereunder
and  thereunder  are  superseded  by  the  terms  of  this  Agreement  and  the  DTPA,  and,  when  negotiated  and  entered  into,  the  SDEA,  Supply
Agreement,  and  Quality  Agreement,  including  the  Existing  CDA,  which  is  hereby  terminated  effective  as  of  the  Effective  Date.  This
Agreement may be amended only by an instrument in writing duly executed on behalf of all of the Parties. In case of inconsistencies between
this Agreement and any Schedule hereof, the terms of this Agreement will prevail unless the Parties agree explicitly that the Schedule should
prevail.

17.3

Force Majeure

.  If the performance of any part of this Agreement by a Party is prevented, restricted, interfered with, or delayed by an occurrence
beyond the control of such Party (and which did not occur as a result of such Party’s financial condition, negligence, or fault), including fire,
earthquake,  flood,  embargo,  power  shortage  or  failure,  acts  of  war  or  terrorism,  insurrection,  riot,  lockout  or  other  labor  disturbance,
governmental  acts  or  orders  or  restrictions  (even  if  foreseeable  as  a  result  of  the  COVID-19  pandemic),  pandemic  (including  COVID-19,
even though foreseeable), or other acts of God, such Party shall, upon giving written notice to the other Party,

119

 
 
be  excused  from  such  performance  to  the  extent  of  such  prevention,  restriction,  interference,  or  delay,  but  the  affected  Party  shall  use  its
Commercially  Reasonable  Efforts  to  avoid  or  remove  such  causes  of  non-performance  and  shall  continue  performance  with  the  utmost
dispatch whenever such causes are removed.  Without limiting the foregoing, when such circumstances arise, the Parties shall negotiate in
good faith any modifications of the terms of this Agreement that may be necessary or appropriate in order to arrive at an equitable solution.

17.4

Costs and Expenses.

  Except as otherwise expressly set forth in this Agreement, each Party shall bear its own costs and expenses in performing its

obligations under this Agreement.

17.5

Waiver

.    The  failure  of  either  Party  to  require  performance  by  the  other  Party  of  any  of  such  other  Party’s  obligations  under  this
Agreement will in no manner affect the right of such Party to enforce the same at a later time.  No waiver by any Party of any condition, or of
the breach of any provision, term, representation, or warranty contained in this Agreement, will be deemed to be, or construed as, a further or
continuing waiver of any such condition or breach, or of any other condition or of the breach of any other provision, term, representation, or
warranty hereof.  

17.6

Remedies

.  The remedies provided in this Agreement are not exclusive and a Party suffering from a breach or default of this Agreement may

pursue all other available remedies, both legal and equitable, alternatively, or cumulatively.

17.7

Severance

.  If any provision or portion thereof in this Agreement is for any reason invalid, illegal, or unenforceable, then the same will not
affect  any  other  portion  of  this  Agreement,  as  it  is  the  intent  of  the  Parties  that  this  Agreement  will  be  construed  in  such  fashion  as  to
maintain its existence, validity, and enforceability to the greatest extent possible.  In any such event, this Agreement will be construed as if
such provision or portion thereof had never been contained in this Agreement, and there will be deemed substituted therefor such provision as
will most nearly carry out the intent of the Parties as expressed in this Agreement to the fullest extent permitted by Applicable Law unless
doing  so  would  have  the  effect  of  materially  altering  the  rights  and  obligations  of  the  Parties,  in  which  event,  this  Agreement  may  be
terminated by mutual written agreement of the Parties.

17.8

Section 2.6(b).  If Apellis has failed, for a period of [**] to purchase a quantity of Product equal to or greater than the [**]
previous Purchase Orders, then Bachem may reduce the Safety Stock to a level reflecting the reduction in actual purchases
by Apellis for such [**] period.  Unless mutually agreed to otherwise, Bachem will manage Safety Stock on a “First In, First
Out” basis to fulfil Apellis purchase orders for Product on a routine basis.

(b) Bachem shall replenish its Safety Stock of each of the raw materials set forth on Schedule 2.6 within [**] of use pursuant to
Section  2.6(a)  (the  “Replenishment  Period”).    Bachem  shall  within  [**]  of  the  end  of  the  Replenishment  Period  notify
Apellis in writing of its inability to replenish the Safety Stock.

2.7
Qualification and Validation of Bachem [**] Facility.  Bachem, at its cost, shall be responsible for qualifying and Validating
the Equipment as appropriate (including conducting installation, operational and performance qualification), production, cleaning, packaging,
process and any other appropriate steps performed at the Bachem [**] Facility in accordance with the Applicable Laws (including cGMPs)
and Bachem’s SOPs.  If any Agency finds Bachem’s Validation procedures to be unacceptable, then all Validation must be repeated to meet
the  criteria  given  in  the  regulatory  requirements  and  guidelines  and  to  receive  all  Agency  approvals.   All  costs  for  such  Agency  requests
resulting solely from an Apellis submission and specific to the Drug Substance and not applicable generally to products Manufactured at the
Facility shall be borne by Apellis. The allocation of costs for Agency requests that are applicable generally to products Manufactured at the
Facility shall be mutually agreed by the Parties.

2.8
Qualification and Validation of Second Bachem [**] Facility. Within [**] following the Effective Date, the Parties shall confer
regarding (i) the timeline for regulatory approval of the Bachem [**] Facility, (ii) a schedule for qualifying and Validating  the  Equipment
(including  conducting  installation,  operational  and  performance  qualification),  production,  cleaning,  packaging,  process  and  any  other
appropriate  steps  performed  at  Bachem’s  [**]  Facility  in  accordance  with  Applicable  Laws  (including  cGMPs);  and  (ii)  the  allocation  of
costs required qualify and Validate the Bachem [**] Facility.  Qualification and Validation procedures used by Bachem immediately prior to
the  Effective  Date  may  be  used;  provided  that  such  procedures  (i)  are  found  to  be  acceptable  to  Apellis,  (ii)  meet  applicable  regulatory
requirements and (iii) are found acceptable by Agency inspectors, if applicable.  If Apellis or any Agency

 
 
 
 
 
finds Bachem’s qualification or Validation procedures to be unacceptable, then all qualification and Validation must be repeated to meet the
criteria  of  all  applicable  regulatory  requirements  and  guidelines  and  to  receive  all  Agency  and  Apellis  approvals.    Notwithstanding  the
foregoing,  if  Apellis  reasonably  finds,  or  any  Agency  finds,  Bachem’s Validation  or  qualification  procedures  to  be  unacceptable,  then  all
Validation or qualification must be repeated to meet the criteria given in the cGMPs. All costs for such Agency requests resulting solely from
an Apellis submission and specific to the Drug Substance and not applicable generally to products Manufactured at the Facility shall be borne
by  Apellis.  The  allocation  of  costs  for  Agency  requests  that  are  applicable  generally  to  products  Manufactured  at  the  Facility  shall  be
mutually agreed by the Parties.  

2.9
Approved  Manufacturer.  Bachem  shall,  within  [**]  of  Apellis’  request  at  any  time  after  a  Product  has  received  Regulatory
Approval,  assist  Apellis  in  the  [**]  of  one  or  more  Apellis’  designated  alternative  supplier(s)  of  Drug  Substance  (each,  an  “Approved
Manufacturer”).  [**].  Apellis shall require any Approved Manufacturer to agree in writing to observe the terms of this Agreement relating
to confidentiality and the manufacture of Drug Substance.  [**].

2.10
Person in Facility.  Apellis may have a mutually agreed to number of employees present during mutually agreed stages of the
Manufacturing of Drug Substance for the purposes of observing and documenting Manufacturing of the Drug Substance.  During such time,
such employees shall have access to those portions of the Facility where Drug Substance is Manufactured and full visibility and transparency
to the activities being undertaken with respect to the Manufacture of Drug Substance.  Any Apellis employees who are present at the Facility
shall comply with Bachem’s site regulations and rules and shall conduct themselves in a manner that minimizes disruptions of operations at
the Facility or distractions to personnel performing such operations. Apellis shall not be obligated to pay for such visits.  For purposes of
clarity,  the  Person(s)  so  appointed  by  Apellis  shall  remain  an  employee(s)  of  Apellis  and  there  shall  not  be  created  any  form  of
employer/employee relationship with Bachem.  

2.11
Samples.  Upon Apellis’s request, Bachem will provide to Apellis, [**], samples  of Drug Substance from an Apellis-specified
Batch in quantities and sizes reasonably requested by Apellis, as set forth in Schedule 2.11, for inspection, testing and analysis.  Bachem will
ship such samples, at Apellis’ cost, as requested by Apellis to a Apellis designated address.

2.12
Materials. With the exception of the Apellis Supplied Materials referred to in Section 2.13, if any, Bachem shall be responsible
for  procuring  all  Materials,  in  adequate  quantities  to  Manufacture  Drug  Substance.    Bachem  shall  purchase  adequate  quantities  of  such
Materials and shall be responsible for negotiating the price for such Materials.  For clarity, the Supply Price takes into account the costs of
such Materials.

2.13

Apellis Supplied Materials.  

(a) Apellis shall supply (or have supplied) to Bachem those quantities of the Material set forth on Schedule 2.13 (the “Apellis
Supplied  Materials”)  that  Apellis  determines  are  reasonably  necessary  for  Bachem  to  Manufacture  the  quantities  of  Drug
Substance that are ordered.  Such Apellis Supplied Materials shall be delivered by or on behalf of Apellis to the applicable
Facility  accompanied  by  a  Certificate  of  Analysis.    Notwithstanding  the  delivery  of  the  Apellis  Supplied  Materials  to
Bachem,  as  between  the  Parties,  such  Apellis  Supplied  Materials  shall  at  all  times  remain  the  property  of  Apellis.    Upon
receipt of the Apellis Supplied Materials, Bachem shall perform testing as agreed in the Quality Agreement to confirm that
such Apellis Supplied Materials are not defective, and Bachem shall immediately notify Apellis in writing of any obvious
defects in the Apellis Supplied Materials.  All Apellis Supplied Materials supplied to Bachem shall be handled, stored and
maintained by Bachem in accordance with

 
 
 
Applicable Law (including cGMPs and, if and to the extent applicable, cGDPs) and in a separate, secured storage area and
clearly  marked  and  identified  by  Bachem  as  the  property  of  Apellis.    Bachem  will  have  the  risk  of  loss  or  damage  to  the
Apellis  Supplied  Materials  while  in  the  possession  of  Bachem,  should  they  not  be  stored  under  the  correct  conditions  as
indicated  on  the  manufacturer’s  Certificate  of  Analysis  for  such  Apellis  Supplied  Materials.    Bachem  acknowledges  that
certain Apellis Supplied Materials may have biological or chemical properties that are unknown or unexpected at the time of
transfer and that such Apellis Supplied Materials are transferred to Bachem with no warranties, express or implied, including
any warranty of merchantability or fitness for a particular purpose and must be used only as described in this Agreement.
Apellis shall notify Bachem of any biological or chemical hazards that do become known to Apellis.  Bachem shall not allow
any pledge, lien, restriction, claim, charge, security interest and/or other encumbrance to be placed on the Apellis Supplied
Materials.  Unless otherwise consented to by Apellis in writing, Bachem shall not obtain any Apellis Supplied Materials from
any other source.  

(b) Unless otherwise consented to by Apellis in writing, Bachem shall use the Apellis Supplied Materials solely and exclusively
to  Manufacture  Drug  Substance  for  Apellis  in  accordance  with  this  Agreement  and  for  no  other  purpose.    Bachem  shall
withdraw  the  Apellis  Supplied  Materials  from  storage  for  the  performance  of  the  Manufacturing  activities  under  this
Agreement and generally respecting the procedure of first expiry/first out.  At the request and direction of Apellis from time
to time, Bachem shall return to Apellis all or any portion (as requested by Apellis) of unused inventory of Apellis Supplied
Materials.

(c) Bachem shall without undue delay notify Apellis in writing whenever the inventories of Apellis Supplied Materials supplied
by or on behalf of Apellis become insufficient to Manufacture the applicable Product to meet the Delivery Dates specified in
the applicable Firm Orders placed by Apellis under this Agreement.  In addition, Bachem shall provide Apellis with detailed
usage reports of the Apellis Supplied Material for each production lot which shall be provided in writing immediately after
the applicable Batch is produced.

(d) Apellis shall without undue delay notify Bachem in writing whenever it is unable to supply sufficient quantities of Apellis
Supplied Materials.  In the event that Apellis fails to supply sufficient quantities of Apellis Supplied Materials, then Apellis
shall not be deemed to be in breach of this Agreement, and the sole and exclusive remedy of Bachem shall be that Bachem be
relieved of its obligations to Manufacture and timely deliver those quantities of the Drug Substance ordered by Apellis under
this Agreement that Bachem is unable to Manufacture as a direct result of the failure of Apellis to supply such quantities of
Apellis Supplied Materials, until such time as sufficient quantities of Apellis Supplied Materials are supplied by or on behalf
of Apellis (provided, that, for clarity, Bachem shall still be obligated to Manufacture and supply any and all quantities of the
Drug  Substance  ordered  by  Apellis  hereunder  which  can  be  Manufactured  based  on  the  quantities  of  Apellis  Supplied
Materials which have been provided).  Apellis agrees that it shall also pay for any reasonable direct costs (direct labor and
overhead  costs)  incurred  related  to  manufacturing  capacity  that,  as  a  direct  result  of  Apellis’  failure  to  supply  necessary
Apellis Supplied Materials, could have been utilized for other purposes, provided Bachem utilizes Commercially Reasonable
Efforts to utilize the manufacturing capacity that is not utilized by Apellis for other purposes.  

(e) Bachem  shall  be  responsible  for  the  risk  of  loss  of  Apellis  Supplied  Materials  upon  delivery  of  such  Apellis  Supplied
Materials to Bachem. Bachem will be financially responsible for any loss of such Apellis Supplied Materials to the extent
such loss results from (i) breach of this Agreement by Bachem or (ii) the negligence or wilfull misconduct of Bachem (or
Bachem’s

 
 
 
 
 
 
 
Affiliates, agents or contractors), in which case, Bachem shall be responsible for, and shall reimburse Apellis for, the costs of
such Apellis Supplied Materials, plus any shipping costs and other out-of-pocket costs (e.g., duties, taxes (including, VAT, if
applicable),  testing  and  other  similar  costs)  incurred  by  or  on  behalf  of  Apellis  with  respect  to  such  Apellis  Supplied
Materials.  Bachem shall not be liable for losses during the manufacturing process resulting directly from Supplied Materials
that do not conform to the agreed quality parameters (e.g., specifications, qualified or validated manufacturing process, GMP,
GDP). The Parties shall on [**] basis agree upon the acceptable yield loss thresholds with respect to the quantities of Apellis
Supplied  Materials  that  may  be  lost  in  conducting  the  Manufacturing  process  for  the  Drug  Substance  as  part  of  their  [**]
review  of  Drug  Substance  Batch  yield  pursuant  to  Section  2.3.    In  the  event  that,  with  respect  to  a  given  Batch  of  Drug
Substance Manufactured under this Agreement, the actual yield loss for the applicable Apellis Supplied Material is greater
than the specified acceptable yield loss threshold due to Bachem’s (i) failure to follow the Manufacturing Process (as defined
in  the  Quality  Agreement)  or  the  Quality  Agreement,  (ii)  negligence  or  (iii)  wilfull  misconduct,  then  Bachem  shall  be
responsible for, and shall reimburse Apellis for, the costs of such lost Apellis Supplied Materials that were in excess of the
acceptable yield loss threshold, plus any shipping costs and other out-of-pocket costs (e.g., duties, taxes (including, VAT, if
applicable), testing and other similar costs) incurred by or on behalf of Apellis (or any of its Affiliates) with respect to such
lost Apellis Supplied Materials.  

(f) Apellis  shall  provide  to  Bachem  material  safety  data  sheets  relating  to  the  Apellis  Supplied  Materials,  and  other  similar
information known to Apellis relating to handling, safety and environmental precautions with respect to the Apellis Supplied
Materials, in each case, to the extent in Apellis’ possession.  It is the sole responsibility of the Bachem to communicate such
information  to  its  employees,  agents,  and  representatives  engaged  in  Manufacturing  of  Product  and  furthermore  Bachem
shall ensure that all safety and other procedures outlined in the Apellis IP are followed by Bachem and its employees, agents
and representatives.  

2.14
Storage.    Bachem  shall,  in  accordance  with  the  Applicable  Laws  (including  cGMPs),  and  Drug  Substance  Specifications,
maintain adequate storage accommodations for all of the Materials, Drug Substance and any other materials or products reasonably requested
by Apellis.  Bachem shall notify Apellis immediately whenever the inventories of Materials become insufficient to Manufacture the Drug
Substance to meet the Delivery Date(s).

2.15
Waste.    Bachem  shall  be  solely  responsible  for  maintaining  safety  procedures  in  connection  with  the  Manufacture  of  Drug
Substance and for the generation, treatment, storage and/or disposal of waste relating thereto, all of which shall comply with all Applicable
Laws,  including  all  applicable  environmental  and  occupational  safety  and  health  requirements  in  the  jurisdiction  of  the  Facility.   At  the
request of Apellis, Bachem shall provide a Certificate of Destruction to Apellis upon completion of disposal of any Drug Substance, key-
intermediate or Apellis Supplied Material.

2.16
Subcontracting.  Bachem shall not subcontract any of its obligations under this Agreement to a Third Party without the prior
written  consent  of  Apellis,  with  the  exception  of  certain  post  manufacturing  analytical  testing,  which  may  be  subcontracted  to  various
qualified testing facilities audited and approved by Bachem and listed in the Quality Agreement, subject to compliance with Section 9.2 of
the  Quality  Agreement  including  its  provisions  regarding  resolution  of  Apellis  objections  to  the  use  of  a  proposed  subcontractor.    With
respect to any subcontracting, Bachem shall remain fully responsible and liable for all obligations under this Agreement, and fully guarantees
and  warrants  the  performance  (in  accordance  with  this  Agreement)  of  any  responsibilities  so  subcontracted,  and  assumes  full  vicarious
liability  for  such  activities  performed  by  any  Subcontractor.    Any  subcontracting  of  any  Manufacturing  or  other  activities  under  this
Agreement  shall  be  subject  to  the  terms  and  conditions  of  this  Agreement.    Any  and  all  costs  associated  with  engaging  a  Third  Party
Subcontractor (including any technology transfer to such Third

 
 
 
 
Party  Subcontractor)  shall  be  borne  solely  by  Bachem  and  shall  not  be  included  in  the  Supply  Price,  and  the  use  of  a  Third  Party
Subcontractor shall not result in any increase in the Supply Price, unless Apellis expressly agrees in writing to an increase in the Supply Price
as a result thereof.  For clarity, the consent of Apellis pursuant to this Section 2.16 shall not be required for Subcontractors performing any
Manufacturing  activities  for  Apellis  at  the  Facility  with  respect  to  the  Manufacture  of  Drug Substance immediately  prior  to  the  Effective
Date; such Subcontractors are deemed being authorized by Apellis.

following  the  Effective  Date.  Such  initial  forecast  will  cover  the  first  [**]  following  the  Effective  Date.  Within  [**]
following the commencement of the first full Calendar Quarter in 2020 following the Effective Date, Apellis shall provide
Bachem on a Calendar Quarterly basis, with a [**] rolling forecast, the first [**] of each such forecast will be binding on
Apellis and the remaining [**] of each such forecast shall be non-binding.  

(b) Bachem  shall  communicate  regularly  with  Apellis  during  the  Term  regarding  Bachem’s  ability  to  meet  Apellis’  Drug
Substance  forecast  requirements  and  Safety  Stock  requirements  and  will  promptly  advise  Apellis  in  writing  of  any
anticipated inability to meet such forecasts, explaining the nature, impact and estimated duration of such inability.

3.2
Firm Orders.  Apellis CH shall place Firm Orders for its requirements of Drug Substance in accordance with the binding portion
of its forecast for the relevant period at least [**] before the requested Delivery Date.  The Firm Orders will contain the requested Delivery
Date (month) for each production batch of the Drug Substance. Firm Orders will be made on such form of purchase order or document as
Apellis  may  specify  from  time  to  time  in  writing;  provided  that  the  terms  and  conditions  of  this  Agreement  shall  be  controlling  over  any
terms and conditions included in any Firm Order.  Any term or condition of such Firm Order that is different from or contrary to the terms
and conditions of this Agreement shall be void, unless otherwise agreed between the Parties in writing.

3.3
Additional  Quantities  of  Drug  Substance.    If  Apellis  requires  additional  Drug  Substance  at  any  time  (in  addition  to  the
quantities ordered in accordance with Section 3.2), Apellis shall notify Bachem in writing (and shall deliver a Firm Order to Bachem for such
additional  quantities)  and  Bachem  shall  use  Commercially  Reasonable  Efforts  to  supply  such  additional  quantities  of  Drug  Substance  for
Apellis, subject to its existing commitments.

3.4
Delivery Against Firm Orders.  Bachem will acknowledge acceptance of all Firm Orders within [**] following receipt. Bachem
has  the  right  to  refuse  a  Firm  Order  in  the  event  and  to  the  extent  such  Firm  Order  is  for  a  quantity  of  Drug  Substance  that  exceeds  the
quantity  set  forth  in  the  forecast  most  recently  submitted  for  such  month;  provided  that  Bachem  may  accept  such  Firm  Order  with  the
understanding that while it will use Commercially Reasonable Efforts to supply such excess quantity, but shall not be liable for its failure to
supply such excess quantity. Bachem shall Deliver Drug Substance only against specific Firm Orders Bachem shall submit mutually agreed
[**]  documentation  to  Apellis  for  its  review  and  approval.  [**].  Notwithstanding  the  above,  Bachem  shall  Deliver  Drug  Substance  under
each  Firm  Order  no  later  than  the  Delivery  Date  specified  in  the  applicable  Firm  Order;  provided,  however,  that  no  Delivery  of  Drug
Substance shall be made more than [**] in advance of the date specified for Delivery in a Firm Order without Apellis’ prior written approval.
Should  Apellis  be  unable  to  accept  shipment  on  the  agreed  Delivery  Date  in  the  applicable  Firm  Order,  Bachem  may  transfer  the  agreed
quantity of Drug Substance

 
 
 
 
in the Firm Order to the Customer warehouse on the agreed Delivery Date.  The Facility shall be indicated on documents accompanying each
Delivery  of  Drug  Substance.    In  the  event  Bachem  will  fail  to  meet  a  Delivery  Date  set  forth  in  a  Firm  Order,  Bachem  shall  bear  the
incremental costs required for expedited transport above and beyond the cost incurred by the method outlined in the Delivery Terms. In the
event  that  Apellis  fails  to  take  delivery  of  the  Drug  Substance  on  the  Delivery  Date,  Bachem  may  transfer  the  Drug  Substance  to  the
customer  warehouse,  and  Bachem  shall  invoice  the  Firm  Order  transferred  to  storage  within  [**]  of  Apellis’  receipt  of  the  [**]
documentation.  At this time Bachem may invoice Apellis, and ownership of said Drug Substance  will  transfer  to  Apellis. Apellis  will  be
responsible for any costs incurred by Bachem in connection with a delay in delivery.

3.5
Delivery.  Bachem shall effect Delivery of each Firm Order in accordance with Applicable Laws (including cGMPs and, if and to
the extent applicable, cGDPs) and the Drug Substance Specifications (and for clarity, Bachem shall only effect Delivery of Drug Substance
pursuant to a Firm Order).  Bachem shall Deliver or arrange for Delivery of Drug Substance in accordance with the Delivery Terms, in order
to fill such Firm Order.  Each container shall be marked as to the identity of the Drug Substance, the quantity of Drug Substance, the related
Firm Order number, and any other information required by the Firm Order.  Except as otherwise provided in Section 3.10(b), Bachem shall
bear  all  risk  of  loss  or  damage  with  respect  to  Drug  Substance(s)  until  such  Drug  Substance(s)  ownership  is  transferred  to  Apellis  in
accordance with Section 3.8.  Each Delivery of Drug Substance shall be accompanied by a packing slip and a Material Safety Data Sheet, and
Bachem’s Certificate of Analysis for such Drug Substance.  Bachem shall not Deliver Drug Substance unless and until such Drug Substance
has been quality released by Bachem.  It is also Bachem’s responsibility at its own cost to collect all necessary information for the Annual
Reports for FDA. The copy of each Annual Report is to be provided to Apellis upon request.

3.6
Acceptance; Rejection.  In  the  event  that  any  Drug  Substance  delivered  to  Apellis  or  any  Apellis  designated  location  fails  to
conform to the Drug Substance warranties set forth in Section 8.2, Apellis may reject such shipment by providing Bachem written notice
within  [**]  of  the  shipment  of  the  Drug  Substance.   Apellis  will  have  the  right  to  test  any  quantity  of  the  Drug  Substance  delivered  by
Bachem  in  order  to  verify  that  such  quantity  satisfies  the  Specifications  but  will  not  have  any  obligation  to  do  so  unless  required  by
Applicable Law.  Any notice of rejection by Apellis shall specify the nonconformity.  If there is no dispute between the Parties relating to the
existence of the nonconformity, any quantity of the Drug Substance supplied by Bachem does not conform to the Drug Substance warranties
set forth in Section 8.2, Bachem may, at Apellis’s election and Bachem’s agreement, reprocess or rework the rejected Drug Substance.  If
reprocessing  or  reworking  is  not  otherwise  feasible,  Bachem  shall  promptly  (i)  replace  such  nonconforming  Drug  Substance  in  a  timely
manner at no additional cost, or (ii) credit Apellis’ account for or refund the price invoiced for such nonconforming Drug Substance.  Any
dispute between the Parties regarding whether Drug Substance fails to conform to the Drug Substance warranties set forth in Section 8.2 shall
be resolved in accordance with the procedure set forth in Section 3.7. Apellis retains the right to determine the disposition of any and all Drug
Substance Manufactured under this Agreement; provided, however, that Bachem shall have the right to offer for sale to Apellis any excess or
nonconforming  Drug  Substance  Manufactured  hereunder;  provided,  further,  however,  that  any  such  excess  or  nonconforming  Drug
Substance not offered to Apellis or not purchased by Apellis shall be promptly and properly destroyed by Bachem.  Nothing in this Section
3.6 shall limit the rights of Apellis to seek damages or otherwise exercise its rights to remedies after acceptance of Drug Substance that fails
to conform to the Drug Substance warranties set forth in Section 8.2 if the nonconformity is a Latent Defect, provided that Apellis provides
Bachem with prompt notice of such Latent Defect after discovery thereof and prior to the stated expiration date of such Drug Substance.

3.7
Conflict Resolution regarding Deficiencies.  In the event that a dispute arises between the Parties regarding whether or not any
Drug Substance fails to conform to the Drug Substance warranties set forth in Section 8.2, they shall resolve such dispute in accordance with
this Section 3.7.  The Parties, acting

 
 
through their appropriate scientific and technical personnel shall promptly communicate in person or by audio conference or videoconference
to  determine  whether the scientific  methods  being  performed  by  or  on  behalf  of  each  party  to  evaluate  the  alleged  conformity  are  being
performed in  the  same  manner  and  if  they  are  not  whether  such  difference  is  the  basis  for  the  dispute.    The  Parties  shall  next  exchange
samples of the Drug Substance from the Batch that is the subject of the dispute using a mutually agreed and carefully controlled process, for
testing by each Party to determine whether the alleged nonconformity is due to the treatment of the Drug Substance samples being tested is
the basis for the dispute.  If the dispute remains unresolved, the Parties, acting through their appropriate scientific and technical personnel
shall meet to work through the analysis of one or more mutually agreed sample(s) taken from the Drug Substance Batch that is the subject of
the dispute.  If the Parties fail to resolve the dispute using these methods within [**] after the dispute arises, then the Parties shall submit a
sample of the Drug Substance Batch that is the subject of the dispute to an independent test facility to be agreed upon by both Parties, such
agreement not to be unreasonably withheld, and to accept the results of the testing performed by that independent testing facility as binding
with regard to whether the Drug Substance from the Batch that is the subject of such dispute conforms to the Drug Substance warranties set
forth in Section 8.2.  Apellis will engage the independent test facility and pay the charges for such testing unless the results show that the
applicable Drug Substance was nonconforming, in which case Bachem shall pay the charges for such testing (or reimburse Apellis if it has
already paid such charges).

(e) Disagreements among the Supply Committee shall be resolved via good-faith discussions; provided, that in the event of a
disagreement that cannot be resolved within [**] after the date on which the disagreement arose, the matter shall be referred
to the Parties for resolution in accordance with Section 11.1.

(f) Unless otherwise agreed by the Parties, the term for the Supply Committee shall commence on the date it is established by
the Parties and continue until all Products have been launched in all countries of the Territory, unless an earlier termination
date is mutually agreed by the Parties.

4.2 Changes and Change Control.

(a) All  changes  requiring  Apellis  prior  written  consent  shall  be  handled  in  accordance  with  the  obligations  set  forth  in  the

Quality Agreement.  

(b) Any change shall, in each instance, comply with the Applicable Laws (including cGMPs) and shall be made in accordance
with the Quality Agreement. In the event that Bachem is required to implement a Major Change (as defined in Section 11.1
of  the  Quality  Agreement)  in  order  to  comply  with  the  Applicable  Laws  (including  cGMPs)  or  such  Major  Change  is
otherwise  agreed  to  by  Apellis  in  writing,  Bachem  shall:  (x)  immediately  notify  Apellis  of  such  Major  change  and  use
Commercially Reasonable Efforts to implement such Major Change as soon as reasonably practicable or mutually agreed; (y)
mutually  agree  with  Apellis  on  a  course  of  action  to  ensure  that  all  Drug  Substance  Manufactured  following  such  Major
change meets the Drug Substance Specifications and the Drug Substance quality and yields achieved prior to such

 
 
 
 
 
 
 
 
 
change; and (z) provide Apellis with all information with respect to the Manufacture of the Drug Substance in connection
with such change reasonably needed to amend any regulatory filings.  To the extent permitted by Applicable Laws, Bachem
shall  continue  to  supply  Apellis  with  unchanged  Drug  Substance  until  such  time  Apellis  informs  Bachem  that  the  Drug
Substance Manufactured following such change is permitted under the amended regulatory filings therefor.  In the event that
Bachem  intends  to  implement  Major  Change,  Apellis  shall  work  in  a  timely  fashion  to  provide  any  required  response  to
Bachem without undue delay and approval of such changes by Apellis shall not unreasonably be withheld or delayed. It shall
be solely the responsibility of Apellis US to evaluate if such a change is in conformance with their regulatory filing and to
use  at  least  Commercially  Reasonable  Efforts  to  adapt  such  filing  for  mutually  agreed  changes  and  changes  required  by
Applicable Laws (including cGMPs) or Agencies.  

(c) Prior to implementing any such Major Change, the Parties shall agree on the reasonable costs thereof; provided that Bachem
shall use Commercially Reasonable Efforts to mitigate the costs thereof.  Notwithstanding the foregoing, (i) if the change is
required by Applicable Laws and such required change solely benefits the Manufacture of the Drug Substance, then Apellis
shall be responsible for reimbursing Bachem for the costs of such required change and (ii) in all other cases, Bachem shall
bear all costs of such change.  

4.3
Discretionary  Changes.    In  the  event  that  either  Party  desires  to  propose  discretionary  changes  (i.e.,  changes  which  are  not
required  by  cGMPs  or  other  Applicable  Laws)  during  the  Term  to  the  Drug  Substance  Specifications  or  to  the  Manufacturing  process  (in
each  case,  which  discretionary  changes  would  otherwise  require  consent  as  set  forth  in  Section  4.2(a)),  the  Parties  shall  discuss  such
discretionary changes and any Manufacturing issues identified by either Party in connection with implementing such change.  In all cases,
such  discretionary  changes  shall  be  made  in  accordance  with  any  change  control  procedures  in  the  Quality  Agreement  to  the  extent
applicable.    The  provisions  of  Sections  4.2(b)  and  4.2(c)  shall  apply  with  respect  to  implementing  any  such  discretionary
change.  Notwithstanding the foregoing, in all cases, the Drug Substance Specifications may be amended or supplemented from time to time
by Apellis upon written notice to Bachem in accordance with any change control procedures in the Quality Agreement.

4.4
Manufacturing at Facility.  Bachem shall Manufacture all Drug Substance supplied hereunder at the Facility.  Manufacturing of
Drug Substance may not be relocated from the Facility without Apellis’ prior written consent (in its sole discretion).  Any such relocation of
the  Manufacturing  of  Drug  Substance  shall  comply  with  the  Applicable  Laws  (including  cGMPs)  and  shall  be  made  in  accordance  with
Sections 4.2(b) and 4.2(c), and the Quality Agreement, to the extent applicable.  Without limiting the foregoing, in the event that Bachem
desires to relocate the Manufacturing of Drug Substance, in connection with such relocation, the Parties shall discuss any amendments to this
Agreement  as  reasonably  requested  by  Apellis  or  the  Bachem  (as  the  case  may  be),  including  with  respect  to  (i)  the  Delivery  Terms,  (ii)
provisions related to transfer of title, in each case, to take into account the relocation of such activities, and (iii) the procedures to be followed
to  secure  any  Regulatory  Approvals  required  by  in  connection  with  such  relocation.    Bachem  shall  be  responsible  for  the  costs  of  any
relocation and any Drug Substance cost increase in connection with such relocation.  

4.5
Process  Yield.    The  Parties  will  meet  on  [**]  basis  during  the  Term  to  review  the  Batch  yields  for  the  Drug  Substance
Manufactured during the prior [**].  If the Drug Substance Batch production yield is repeatedly above or below the agreed upon average
yield described in Section 2.3, as such average yield may be adjusted during the Term pursuant to the Continuous Improvement Program, the
Parties will evaluate such trends and agree to negotiate in good faith a fair and equitable adjustment to the pricing for the Drug Substance.

quality and Apellis service improvement programs by seeking productivity

Continuous  Improvement.    Bachem  shall  use  Commercially  Reasonable  Efforts  to  identify  and  implement  continuous  cost,

 
 
 
 
improvements,  by  minimizing  waste  and  improving  Drug  Substance  yields,  and  by  (i)  purchasing  quality  Materials  at  lower  cost,  (ii)
improving Manufacturing processes within the validated parameters for the Drug Substance, (iii) streamlining organizational processes, and
(iv) reducing cycle times and lead times. The Parties shall meet at least once per Calendar Year during the Term to discuss and agree on (a)
objectives  for  a  continuous  improvement  program,  including  cost  improvements  that  may  be  obtained  in  respect  of  the  matters  described
above  (“Continuous  Improvement  Program”)  and  (b)  the  means  of  measuring  and  implementing  the  results  of  the  Continuous
Improvement Program.  Progress against objectives shall be measured quarterly.  Bachem shall use all reasonable endeavors to achieve the
agreed objectives and targets identified for the relevant period.  The up front costs for any such agreed upon development improvements shall
be  apportioned  between  the  Parties  by  mutual  agreement.  The  net  benefits  of  cost  reductions  and  improved  efficiencies  shall  be  shared
equally by the Parties, including as reductions to the Supply Price under this Agreement.  In such case, the Parties shall reasonably discuss
and agree on the amount of such reductions to the Supply Price.

ARTICLE 7

PAYMENT AND TAXES

7.1
Supply Price.    For  each  unit  of  Drug  Substance  ordered  by  Apellis  under  Firm  Orders  and  supplied  by  Bachem  to  Apellis  in
accordance with the terms and conditions of this Agreement, Apellis shall pay Bachem the Supply Price set forth on Schedule 7.1 (“Supply
Price”).    The  Supply  Price  shall  be  determined  in  accordance  with  Schedule  7.1  based  upon  the  aggregate  quantity  of  Drug  Substance
subject to a Purchase Order submitted by Apellis in each Calendar Year. Subject to adjustment pursuant to Section 7.4, the maximum Supply
Price will be fixed for the initial Term of this Agreement and subject to adjustment in accordance with Section 10.1 in any renewal Term.

7.2
Invoicing; Payment. Bachem shall provide Apellis with an Invoice for each Batch of Drug Substance Delivered against a Firm
Order placed by Apellis in accordance with this Agreement, which will be based on the then current Supply Price.  Such Invoices shall be
delivered electronically to [**] upon release of a batch.  Apellis shall pay each Invoice within [**] from the date the Invoice is delivered.  All
payments under this Agreement shall be made in U.S. Dollars by wire transfer into an account designated by the receiving Party.  

Annual  True  Up.  Within  [**]  prior  the  end  of  each  Calendar  Year,  the  Parties  shall  calculate  the  actual  amount  of  Drug
7.3
Substance ordered for delivery in such Calendar Year under this Agreement. If the actual amount of Drug Substance ordered for delivery in
such Calendar Year is different than the amount of Drug Substance forecasted for such Calendar Year, and as a result of such difference, a
different price per gram should have been used to calculate the supply price based on the sum total of such actual volume ordered under this
Agreement, the Parties shall recalculate the Supply Price, and Apellis or Bachem, as applicable, shall issue an invoice or credit memo in the
amount necessary to reconcile the difference between the Supply Price paid by Apellis based on the forecasted volume to be ordered and the
actual volume ordered by Apellis for such period.

7.4
Process Improvements and Sharing of Cost Efficiencies. If Bachem is able to realize any productivity improvements or cost
improvements through the Continuous Improvement Program, or otherwise, Bachem shall pass onto Apellis the benefit of such quantifiable
cost savings and efficiencies as

 
 
can be verified by documentary evidence and in the manner as mutually agreed to in Section 4.6.  

7.5
Taxes.  In the event any payments made pursuant to this Agreement are or become subject to withholding taxes under the laws or
regulations  of  any  jurisdiction,  the  Party  making  such  payment  shall  be  entitled  to  deduct  and  withhold  the  amount  of  such  taxes  for  the
account of the payee to the extent required by Applicable Law; and such amounts payable to the payee shall be reduced by the amount of
taxes deducted and withheld (subject to the last sentence of this Section).  Any such withholding taxes required under Applicable Law to be
paid  or  withheld  shall  be  an  expense  of,  and  borne  solely  by,  the  payee.  If  the  Party  making  payment  pursuant  to  this  Agreement  fails  to
deduct and withhold all or a portion of the amount of tax required by Applicable Law to be deducted and withheld and such Party is required
by Applicable Law to pay all or a portion of such tax to a governmental authority for the account of the payee, payee shall, upon request from
the other Party, immediately pay to the other Party an amount equal to the amount paid to the governmental authority for the account of the
payee.  However, in the event that there are withholding taxes on payments made pursuant to this Agreement that are in excess of what the
payee Party may recover, then the Parties shall discuss responsibility for such withholding taxes in good faith.

7.6
Late Payment.  If a Party does not receive payment of any sum due to it on or before the due date, simple interest shall thereafter
accrue on the sum due to such Party until the date of payment at the per annum rate of [**] percent ([**]%) over the then-current prime rate
quoted by Citibank in New York City or the maximum rate allowable by Applicable Law, whichever is lower.  In the event Apellis desires to
dispute in good faith any Invoice, or item(s) under any Invoice, Apellis will provide Bachem with a written notice setting forth the details of
the disputed Invoice or item(s) and the amount in question. Apellis will timely pay to Bachem any other undisputed amounts on any such
Invoice. The Parties will work together, in good faith, to resolve such dispute within [**] after such notice of dispute is sent. Apellis’ failure
to  pay  an  Invoice  or  item  of  an  invoice  that  it  disputes  in  good  faith  shall  not  constitute  a  material  breach  under  this  Agreement.    If,
notwithstanding  such  efforts,  the  Parties  are  unable  to  resolve  a  dispute  within  such  [**]  period,  the  Parties  shall  resolve  such  dispute
pursuant to the provisions of Article 11.  In the event the Parties have not resolved such a dispute within the [**] period set forth above and
escalate  such  dispute  for  resolution  pursuant  to  the  provisions  of  Article  11,  Bachem  shall  have  the  option  to  suspend  work  under  this
Agreement until the dispute is resolved.

ARTICLE 10

TERM AND TERMINATION

10.1
Term.  The initial term of this Agreement shall commence upon the Effective Date and, unless earlier terminated pursuant to this
Article 9, shall remain in effect until the five (5) year anniversary of the Effective Date.  Thereafter, this Agreement shall automatically renew
for an additional 2-year term (the initial term and such renewal term (if applicable) the “Term”). At least twenty four (24) months prior to the
end  of  the  initial  Term,  Bachem  shall  notify  Apellis  in  writing  if  it  is  willing  to  continue  to  Manufacture  and  supply  Drug  Substance
following the end of the initial Term.  If Bachem so notifies Apellis in writing, then Apellis shall have the right (but not the obligation), for a
period of twelve (12) months thereafter, to discuss with Bachem the pricing terms that would apply during such renewal Term, and in the
event that Apellis and Bachem agree on such pricing terms in writing, then they shall enter into an amendment to this Agreement for the
pricing terms applicable for the renewal Term.  If Bachem does not so notify Apellis in writing that it is willing to supply beyond the end of
the initial Term, then Bachem acknowledges that Apellis shall have the right, but not the obligation, to increase orders of Drug Supply under
this Agreement during the remainder of the initial Term in order to build inventory and Bachem shall fill such orders in accordance with this
Agreement subject to its available capacity in the context of its existing organization.  For clarity, (i) neither Party shall have any obligation
to renew this Agreement unless and until agreed to by such Party, and (ii) unless otherwise expressly agreed to by the Parties in writing, any
new or different terms which are negotiated as part of the renewal, if any, shall only apply during the renewal Term and shall not in any way
alter the terms of this Agreement during the initial Term.

10.2
Termination for Material Breach. Either Party (the “Non-Breaching Party”) may terminate this Agreement in the event the
other Party (the “Breaching Party”) commits a material breach of this Agreement or the Quality Agreement, and such material breach has
not been cured within [**] after receipt of written notice of such breach by the Breaching Party from the Non-Breaching Party (the “Cure
Period”).  The written notice describing the alleged material breach shall provide sufficient detail to put the Breaching Party on notice of
such material breach. Any termination of this Agreement pursuant to this Section 10.2 shall become effective at the end of the Cure Period,
unless the Breaching Party has cured any such material breach and notified the Non-Breaching Party thereof prior to the expiration of such
Cure Period, or, if such material breach is not reasonably susceptible to cure within the Cure Period, then, the Non-Breaching Party’s right of
termination shall be suspended only if, and for so long as, the Breaching Party has provided to the Non-Breaching Party a written plan that is
reasonably calculated to effect a cure of such material breach, such plan is accepted by the Non-Breaching Party (such acceptance not to be
unreasonably  withheld,  delayed  or  conditioned),  and  the  Breaching  Party  commits  to  and  carries  out  such  plan  as  provided  to  the  Non-
Breaching Party.  The right of either Party to terminate this Agreement as provided in this Section 10.2 shall not be affected in any way by
such Party’s waiver of or failure to take action with respect to any previous breach under this Agreement.  

 
 
10.3
has delayed performance by the other Party for more than [**] or an aggregate [**] in any [**] period.

Agency or other governmental authority, or (ii) Bachem fails to satisfy Validation or other cGMP requirements; or (b) if any required license,
permit or certificate of Bachem related to the Facility or the Manufacture of Drug Substance is not approved or not issued, or is deactivated
or withdrawn, by any Agency or other governmental authority.

Termination for Bankruptcy. Either  Party  may  terminate  this  Agreement  in  its  entirety  upon  providing  written  notice  to  the
10.5
other  Party  on  or  after  the  time  that  such  other  Party  (a) makes  a  general  assignment  for  the  benefit  of  creditors,  (b)  files  an  insolvency
petition in bankruptcy, (c) petitions for or acquiesces in the appointment of any receiver, trustee or similar officer to liquidate or conserve its
business  or  any  substantial  part  of  its  assets,  (d)  commences  under  the  laws  of  any  jurisdiction  any  proceeding  involving  its  insolvency,
bankruptcy,  reorganization,  adjustment  of  debt,  dissolution,  liquidation  or  any  other  similar  proceeding  for  the  release  of  financially
distressed debtors, or (e) becomes a party to any proceeding or action of the type described above, and such proceeding or action remains un-
dismissed or un-stayed for a period of more than [**].

(Termination by Apellis) or Section 10.5 (Bankruptcy), Apellis shall (in its discretion) either: (i) keep any or all outstanding
Firm  Orders  in  place  (on  a  Firm  Order-by-Firm  Order  basis  as  determined  by  Apellis),  in  which  case  Bachem  shall
Manufacture and Deliver, in accordance with this Agreement, all quantities of Drug Substance ordered pursuant to such Firm
Orders  (regardless  of  whether  the  Delivery  Date  for  such  Drug  Substance  is  before  or  after  such  termination)  and  Apellis
shall pay the Supply Price with respect to such Drug Substance which meet the representations, warranties and covenants set
forth  in  this  Agreement;  or  (ii)  cancel  any  or  all  outstanding  Firm  Orders  (on  a  Firm  Order-by-Firm  Order  basis  as
determined  by  Apellis),  and  with  respect  to  any  such  cancelled  Firm  Orders,  Apellis  shall  have  no  further  liability  with
respect  thereto;  provided  that  Apellis  shall  only  have  the  right  to  cancel  Firm  Orders  pursuant  to  this  clause  (ii)  if  this
Agreement is terminated by Apellis pursuant to Section 10.2 or Section 10.4.

In the event that this Agreement is terminated by Bachem pursuant to Section 10.2 or by Apellis pursuant to Section 10.4(a)
or  Section  10.3,  Apellis  shall  purchase  the  quantity  of  Safety  Stock  of  Drug  Substance  existing  as  of  the  time  of  such
termination  (if  any)  that  is  in  finished,  packaged  and  labelled  form  (provided  that  all  such  Drug  Substance  meets  the
representations, warranties and covenants set forth in this Agreement), and in connection therewith, Bachem shall Deliver all
such quantities of Safety Stock in accordance with this Agreement, and Apellis shall pay the applicable Supply Price with
respect to such Drug Substance.  Notwithstanding the foregoing or anything to the contrary contained herein, from and after
the delivery of any

 
 
 
 
notice of termination pursuant to this Agreement, Bachem shall not replenish (or otherwise add any additional quantities of
Drug Substance to) any Safety Stock then being held for Apellis.

(c) Upon expiration or termination of this Agreement, Apellis and Bachem shall immediately settle all outstanding invoices and
other monies owed to the other pursuant to this Agreement.  The termination or expiration of this Agreement shall not affect
the  rights  and  obligations  of  the  Parties  accruing  prior  to  such  termination  or  expiration,  including,  but  not  limited  to,
Apellis’  reimbursement  to  Bachem  for  any  work  in  progress  and  all  non-cancelable  commitments  to  purchase  Materials
entered  into  by  Bachem  specifically  to  conduct  the  Services  hereunder  that  Bachem  cannot  reasonably  utilize  in  other
projects and that meet the relevant specifications therefor that had been agreed upon by the Parties in writing.  Subject to the
foregoing,  expiration  or  termination  of  this  Agreement  shall  relieve  and  release  the  Parties  from  any  liabilities  and
obligations under this Agreement, other than those specifically set forth in this Article 9 and those that survive termination in
accordance with Section 10.8.  

10.8
Remedies.    Notwithstanding  anything  to  the  contrary  in  this  Agreement,  except  as  otherwise  explicitly  set  forth  in  this
Agreement, termination or expiration of this Agreement shall not relieve the Parties of any Liability or obligation which accrued hereunder
prior to the effective date of such termination or expiration, nor prejudice either Party’s right to obtain performance of any obligation.  Each
Party shall be free, pursuant to Article 10, to seek, without restriction as to the number of times it may seek, damages, costs and remedies that
may be available to it under Applicable Law or in equity.

accordance with their terms, the following provisions of this Agreement shall survive:  Articles 1, 8, 9, 11 and 12, and Sections 6.1-6.5, 7.3,
7.5, 10.7, 10.8, 13.1-13.2, 13.4-13.5, and 13.7-13.13.  

ARTICLE 11

DISPUTE RESOLUTION  

11.1
Disputes.  The Parties shall initially attempt in good faith to resolve any significant controversy, claim, allegation of breach or
dispute arising out of or relating to this Agreement (hereinafter collectively referred to as a “Dispute”) through negotiations between senior
executives  of  Apellis  and  Bachem.    Only  if  the  Dispute  is  not  resolved  through  negotiations,  may  a  Party  resort  to  litigation.    During  the
pendency of any dispute resolution proceeding between the Parties under this Section 11.1, the obligation to make any payment under this
Agreement from one Party to the other Party, which payment is the subject, in whole or in part, of a proceeding under this Section 11.1, shall
be tolled until the final outcome of such dispute has been established.  Any undisputed payment obligations (including undisputed portions of
a payment obligation that is subject to a proceeding under this Section 11.1) shall not be tolled during such dispute.

ARTICLE 12
INDEMNIFICATION

12.1
Indemnification by Apellis.  Apellis hereby agrees to defend, indemnify and hold harmless Bachem and its Affiliates, and each
of their respective directors, officers, employees, agents and representatives (each, a “Bachem Indemnitee”) from and against any and all
claims, suits, actions, demands, liabilities, expenses and/or losses, including reasonable legal expenses and attorneys’ fees (collectively, the
“Losses”), to which any Bachem Indemnitee may become subject as a result of any claim, demand, action or other proceeding by any Third
Party (each, a “Claim”) to the extent such Losses arise directly or indirectly out of: (a) the breach by Apellis of any warranty, representation,
covenant or

 
 
 
 
agreement made by Apellis in this Agreement; (b) the storage, use, transfer or sale, labeling, packaging, distribution, promotion, marketing,
sale,  or  other  disposition  of  Drug  Substance  (in  each  case  after  Delivery  to  Apellis)  or  the  manufacture,  use,  transfer  or  sale,  labelling,
packaging distribution, promotion, marketing, sale or other disposition of any Product; (c) the failure by Apellis to comply with Applicable
Law  relating  to  the  Product;  (d)  the  negligence,  gross  negligence,  illegal  conduct  or  willful  misconduct  of  Apellis  or  an  Affiliate  or
sublicensee, or any officer, director, employee, agent or representative thereof; or (e) any Claim that the manufacture, use or sale of a Product
infringes any patents, copyrights or trademarks or misappropriates any know-how owned by a Third Party; except, with respect to each of
subsections (a), (b), (c), (d) and (e) above, to the extent such Losses arise directly or indirectly from the negligence, gross negligence, illegal
conduct or willful misconduct of any Bachem Indemnitee or the breach by Bachem of any warranty, representation, covenant or agreement
made by Bachem in this Agreement or are subject to indemnification by Bachem under Section 12.2.

12.2
Indemnification by Bachem.  Bachem hereby agrees to defend, indemnify and hold harmless Apellis and its Affiliates and each
of  their  respective  directors,  officers,  employees,  agents  and  representatives  (each,  a  “Apellis Indemnitee”)  from  and  against  any  and  all
Losses to which any Apellis Indemnitee may become subject as a result of any Claim to the extent such Losses arise directly or indirectly out
of: (a) the breach by Bachem of any warranty, representation, covenant or agreement made by Bachem in this Agreement; (b) the failure of
Drug Substance to meet the Drug Substance warranties set forth in Section 8.2; (c) the failure by Bachem to comply with Applicable Laws
with  respect  to  the  Manufacture  of  the  Drug  Substance;  (d)  the  negligence,  gross  negligence,  illegal  conduct,  or  willful  misconduct  of
Bachem  or  its  Affiliates  or  Subcontractors,  or  any  officer,  director,  employee,  agent  or  representative  thereof;  or  (e)  any  Claim  that  the
Manufacture of Drug Substance infringes any patents, copyrights or trademarks or misappropriates any know-how owned by a Third Party
(except to the extent such Claim is based upon any Apellis IP provided to Bachem); except, with respect to each of subsections (a), (b), (c)
(d)  or  (e)  above,  to  the  extent  such  Losses  arise  directly  or  indirectly  from  the  negligence,  gross  negligence,  illegal  conduct  or  willful
misconduct of any Apellis Indemnitee or the breach by Apellis of any warranty, representation, covenant or agreement made by Apellis in
this Agreement or are subject to indemnification by Apellis under Section 12.1.

12.3

Indemnification Procedures.

(a) Notice.  Promptly after a Bachem Indemnitee or a Apellis Indemnitee (each, an “Indemnitee”) receives notice of a pending
or  threatened  Claim,  such  Indemnitee  shall  give  written  notice  of  the  Claim  to  the  Party  from  whom  the  Indemnitee  is
entitled to receive indemnification pursuant to Sections 12.1 or 12.2, as applicable (the “Indemnifying Party”).  However,
an  Indemnitee’s  delay  in  providing  or  failure  to  provide  such  notice  shall  not  relieve  the  Indemnifying  Party  of  its
indemnification obligations, except to the extent it can demonstrate actual prejudice due to the delay or lack of notice.

(b) Defense.  Upon receipt of notice under this Section 12.3 from the Indemnitee, the Indemnifying Party will have the duty to
either compromise or defend, at its own expense and by counsel (reasonably satisfactory to Indemnitee) such Claim.  The
Indemnifying  Party  will  promptly  (and  in  any  event  not  more  than  [**]  after  receipt  of  the  Indemnitee’s  original  notice)
notify the Indemnitee in writing that it acknowledges its obligation to indemnify the Indemnitee with respect to the Claim
pursuant  to  this  Article  11  and  of  its  intention  either  to  compromise  or  defend  such  Claim.    Once  the  Indemnifying  Party
gives such notice to the Indemnitee, the Indemnifying Party is not liable to the Indemnitee for the fees of other counsel or
any  other  expenses  subsequently  incurred  by  the  Indemnitee  in  connection  with  such  defense,  other  than  the  Indemnitee’s
reasonable out of pocket Third Party expenses related to its investigation and cooperation, except as otherwise provided in
the next sentence.  As to all Claims as to which

 
 
 
 
the  Indemnifying  Party  has  assumed  control  under  this  Section  12.3(b),  the  Indemnitee  shall  have  the  right  to  employ
separate counsel and to participate in the defense of a Claim (as reasonably directed by the Indemnifying Party) at its own
expense;  provided,  however,  that  if  the  Indemnitee  shall  have  reasonably  concluded,  based  upon  a  written  opinion  from
outside legal counsel, that there is a conflict of interest between the Indemnifying Party and the Indemnitee in the defense of
such Claim, the Indemnifying Party shall pay the fees and expenses of one law firm serving as counsel for the Indemnitee in
relation to such Third Party Claim.

(c) Cooperation.    The  Indemnitee  shall  reasonably  cooperate  with  the  Indemnifying  Party  and  its  legal  representatives  in  the
investigation and defense of any Claim.  The Indemnifying Party shall keep the Indemnitee informed on a reasonable and
timely basis as to the status of such Claim (to the extent the Indemnitee is not participating in the defense of such Claim) and
conduct the defense of such Claim in a prudent manner.

(d) Settlement.  If an Indemnifying Party assumes the defense of a Claim, no compromise or settlement of such Claim may be
effected by the Indemnifying Party without the Indemnitee’s written consent (such consent not to be unreasonably withheld,
delayed  or  conditioned).    Notwithstanding  the  foregoing,  the  Indemnitee’s  consent  shall  not  be  required  of  a  settlement
where: (i) there is no finding or admission of any violation of law or any violation of the rights of any person and no effect on
any other claims that may be made against the Indemnitee; (ii) the sole relief provided is monetary damages that are paid in
full by the Indemnifying Party; (iii) the Indemnitee’s rights under this Agreement are not adversely affected; and (iv) there is
a  full  release  of  the  Indemnitee  from  such  Claim.    If  the  Indemnifying  Party  fails  to  assume  defense  of  a  Claim  within  a
reasonable  time,  the  Indemnitee  may  settle  such  Claim  on  such  terms  as  it  deems  appropriate  with  the  consent  of  the
Indemnifying Party (such consent not to be unreasonably withheld, delayed or conditioned), and the Indemnifying Party shall
be obligated to indemnify the Indemnitee for such settlement as provided in this Article 12. It is understood that only Apellis
and Bachem may claim indemnification under this Agreement (on its own behalf or on behalf of its Indemnitees), and other
Indemnitees may not directly claim indemnity under this Agreement.

12.4
Insurance.  Each  Party  shall  procure  and  maintain  insurance  policies  for  the  following  coverages  with  respect  to
product liability, personal injury, bodily injury, and property damage arising out of such Party’s (and its Affiliates’) performance under this
Agreement:    (a)  during  the  Term  of  this  Agreement,  comprehensive  general  liability,  including  broad  form  and  contractual  liability,  in  a
minimum  amount  of  $[**]  combined  single  limit  per  occurrence  (or  claim)  and  $[**]  in  the  aggregate  annually;  and  (b)  prior  to  the  first
commercial sale of Drug Substance or a Product, as applicable, until [**] after the last sale of Drug Substance or a Product, as applicable,
product liability coverage, in a minimum limit of $[**] combined single limit per occurrence (or claim) and $[**] in the aggregate annually.
The policies of insurance required by this Section 12.4 will be issued by an insurance carrier with an A.M. best rating of “A” or better.  Each
Party will provide the other Party with insurance certificates evidencing the required coverage within [**] after the Effective Date and the
commencement of each policy period and any renewal periods.  Each certificate will provide that the insurance carrier will notify the other
Party in writing at least [**] prior to the cancellation or material change in coverage. For clarity, the foregoing insurance requirements shall
not in any way limit a Party’s liability with respect to its indemnification or other obligations under this Agreement.

12.5
Limitation  of  Liability.    EXCEPT  FOR  A  PARTY’S  OBLIGATIONS  SET  FORTH  IN  THIS  ARTICLE  12  AND  ANY
BREACH OF ARTICLE 8, IN NO EVENT WILL EITHER PARTY BE LIABLE TO THE OTHER PARTY (OR THE OTHER PARTY’S
AFFILIATES OR SUBLICENSEES)

 
 
 
 
 
IN CONNECTION WITH THIS AGREEMENT FOR LOST REVENUE, LOST PROFITS, LOST SAVINGS, LOSS OF USE, DAMAGE
TO  GOODWILL,  OR  ANY  CONSEQUENTIAL,  INCIDENTAL,  SPECIAL,  EXEMPLARY,  PUNITIVE  OR  INDIRECT  DAMAGES  IN
CONNECTION  WITH  THIS  AGREEMENT,  HOWEVER  CAUSED,  UNDER  ANY  THEORY  OF  LIABILITY,  INCLUDING
CONTRACT,  NEGLIGENCE,  OR  STRICT  LIABILITY,  EVEN  IF  THAT  PARTY  HAS  BEEN  PLACED  ON  NOTICE  OF  THE
POSSIBILITY OF SUCH DAMAGES.  THIS LIMITATION ALSO APPLIES TO THE EXTENT A PARTY'S LIABILITY IS BASED ON
ACTS  OR  OMISSIONS  OF  ITS  AGENTS,  EMPLOYEES,  SUB-CONTRACTORS,  SUB-SUPPLIERS,  JOINT  VENTURE  PARTNERS
OR  OTHER  THIRD PARTIES ENGAGED  IN  THE  PERFORMANCE  OF  THIS AGREEMENT.  IT  DOES  NOT  APPLY  IN  CASE  OF
WILLFUL  MISCONDUCT  OR  GROSS  NEGLIGENCE  OF  THE  RESPECTIVE  PARTY,  IN  CASE  OF  CLAIMS  BASED  BY
FRAUDULENT  CONCEALMENT  OF  A  DEFECT  (“ARGLIST”),  BODILY  INJURY  OR  DEATH  CULPABLY  CAUSED  BY  THE
RESPECTIVE  PARTY  OR  ITS  AGENTS,  AS  WELL  TO  THE  EXTENT  THE  RESPECTIVE  PARTY’S  LIABILITY  IS  BASED  ON
MANDATORY LAW, SUCH AS APPLICABLE PRODUCT LIABILITY ACTS.

12.6
Damages Cap. IN ADDITION TO THE LIMITATION OF LIABILITY IN SECTION 12.5 EXCEPT FOR (a) EACH PARTY’S
INDEMNIFICATION OBLIGATIONS SET FORTH IN THIS ARTICLE 12; (b) ANY BREACH OF ARTICLE 8 BY SUCH PARTY; AND
(c)  DAMAGES  ARISING  OUT  OF  SUCH  PARTY’S  GROSS  NEGLIGENCE  OR  WILFUL  MISCONDUCT,  EACH  PARTY’S
MAXIMUM AGGREGATE LIABILITY TO COMPENSATE THE OTHER PARTY FOR ALL DAMAGES UNDER THIS AGREEMENT
WILL  BE  SET  ON  A  PER  CALENDAR  YEAR  BASIS  AND  FOR  THE  CALENDAR  YEAR  IN  WHICH  THE  CAUSE  OF  SUCH
LIABILITY LIES OR EXISTS (WHETHER IN CONTRACT, TORT, STRICT LIABILITY, STATUTE, OR OTHERWISE) AND SHALL
BE LIMITED TO A MAXIMUM OF $[**] USD.

payment, to the extent that such nonperformance or delay in performance is not due to its negligence and is caused by any event reasonably
beyond  the  control  of  such  Party,  including  wars,  hostilities,  revolutions,  riots,  civil  commotion,  national  emergency,  strikes,  lockouts,
unavailability of supplies, epidemics, pandemics, fire, flood, earthquake, force of nature, explosion, terrorist act, embargo, or any other Act of
God, (each a “Force Majeure Event”). Notwithstanding the foregoing, the COVID-19 Pandemic shall not be considered a Force Majeure
Event, unless a Party's non-performance or delay in performance is (i) the direct result of orders and regulations of a Governmental Authority
to  combat  the  COVID-19  Pandemic  which  the  addressees  are  legally  obliged  to  comply  with  (e.g.  closure  of  the  Facility,  quarantine
regulations, requisition of production capacities) and/or (ii) such Party has taken Commercially

 
 
 
 
Reasonable  measures  to  avoid  harmful  effects  of  the  COVID-19  Pandemic(  i.e.,  as  set  forth  by  the  regulations  issued  by  the  Swiss
Bundesamt für Gesundheit for Bachem AG, and the applicable California health authority for Bachem Americas, Inc.).  In the event of any
such delay, the delayed Party may defer its performance for a period equal to the time of such delay, provided that the delayed Party gives the
other  Party  prompt written  notice  oif  the  occurrence  of  any  Force  Majeure  Event,  the  nature  thereof,  and  the  extent  to  which  the  delayed
Party will be unable fully to perform its obligations under this Agreement, and uses its good faith efforts to cure the excused breach. In the
event of a Force Majeure that lasts for more than [**] or [**] in any [**] period, the other Party shall have the right upon written notice to the
delayed Party to terminate this Agreement in accordance with Section 10.3.

13.6
Assignment.  Neither Party shall assign this Agreement or an of the rights or obligations hereunder, without the prior written
consent  of  the  other  Party,  except  that  either  party  may,  without  the  other  party’s  consent,  assign  the  Agreement  to  an  Affiliate  or  to  a
successor  to  substantially  all  of  the  business  or  assets  of  the  assigning  company  or  the  assigning  company’s  business  unit  responsible  for
performance of the Agreement.

13.7
Binding Effect; No Third Party Beneficiaries.  This Agreement shall be binding upon and inure to the benefit of, and shall be
enforceable only by, the Parties and their respective successors and permitted assigns.  It is the explicit intention of the Parties that no Person,
other than the named Parties or their successors or permitted assigns, is or shall be entitled to bring any action to enforce any provision of this
Agreement, as a third party beneficiary or otherwise.

Severability.  If any one (1) or more of the provisions of this Agreement (a) is held to be invalid or unenforceable by any court
13.8
of  competent  jurisdiction  from  which  no  appeal  can  be  or  is  taken  or  (b)  a  Governmental  Authority  of  competent  jurisdiction  advises  the
Parties  that  such  provision  violates  Applicable  Law  over  which  such  Governmental  Authority  has  jurisdiction,  the  provision  shall  be
considered severed from this Agreement and shall not serve to invalidate any remaining provisions hereof.  The Parties shall make a good
faith effort to replace any invalid or unenforceable provision with a valid and enforceable provision such that the objectives contemplated by
the Parties when entering this Agreement may be realized.

13.9
Waiver and Non-Exclusion of Remedies.  Any term or condition of this Agreement may be waived at any time by the Party
that is entitled to the benefit thereof, but no such waiver shall be effective unless set forth in a written instrument duly executed by or on
behalf of the Party waiving such term or condition.  The waiver by either Party hereto of any right hereunder or of the failure to perform or of
a breach by the other Party shall not be deemed a waiver of any other right hereunder or of any other breach or failure by such other Party
whether  of  a  similar  nature  or  otherwise.   The  rights  and  remedies  provided  herein  are  cumulative  and  do  not  exclude  any  other  right  or
remedy provided by Applicable Law or otherwise available except as expressly set forth herein.

13.10
Further  Assurance.    Each  Party  shall  duly  execute  and  deliver,  or  cause  to  be  duly  executed  and  delivered,  such  further
instruments and do and cause to be done such further acts and things, including the filing of such assignments, agreements, documents, and
instruments,  as  may  be  necessary  or  as  the  other  Party  may  reasonably  request  in  connection  with  this  Agreement  or  to  carry  out  more
effectively the provisions and purposes hereof.

alteration, amendment, change or addition to this Agreement shall be binding upon the Parties unless reduced to writing and signed by an
authorized officer of each Party.  In the event of any inconsistency between the body of this Agreement and either any Attachments to this
Agreement or any subsequent agreements ancillary to this Agreement, unless otherwise express stated to the contrary in such Attachment or
ancillary agreement, the terms contained in this Agreement shall control.

13.14

but  all  of  which  together  shall  constitute  one  and  the  same  instrument.   This  Agreement  may  be  executed  by  .pdf  or  other  electronically
transmitted signatures and such signatures shall be deemed to bind each Party hereto as if they were the original signatures.
