Overview

PART I

Sorrento Therapeutics, Inc. (Nasdaq: SRNE), together with its subsidiaries (collectively, the “Company”, “we”, “us”, and “our”) is a clinical stage

and commercial biopharmaceutical company focused on delivering innovative and clinically meaningful therapies to address unmet medical needs.

At our core, we are antibody-centric and leverage our proprietary G-MAB™ library and targeted delivery modalities to generate the next generation

of cancer therapeutics. Our fully human antibodies include PD-1, PD-L1, CD38, CD123, CD47, CTLA-4, CD137 and SARS-CoV-2 neutralizing
antibodies, among others. We also have programs assessing the use of our technologies and products in autoimmune, inflammatory, viral and
neurodegenerative diseases.

Our vision is to leverage these antibodies in conjunction with proprietary targeted delivery modalities to generate the next generation of cancer
therapeutics. These modalities include proprietary chimeric antigen receptor T-cell therapy (“CAR-T”), dimeric antigen receptor T-cell therapy (“DAR-T”),
antibody drug conjugates (“ADCs”) as well as bispecific antibody approaches. We acquired Sofusa®, a revolutionary drug delivery technology, in July
2018, which delivers biologics directly into the lymphatic system to potentially achieve improved efficacy and fewer adverse effects than standard
parenteral immunotherapy. Additionally, our majority-owned subsidiary, Scilex Holding Company (“Scilex Holding”), acquired the assets of Semnur
Pharmaceuticals, Inc. (“Semnur”) in March 2019. Semnur’s SEMDEXATM (“SP-102”) compound has the potential to become the first Food and Drug
Administration (“FDA”)-approved epidural steroid product for the treatment of sciatica. In response to the global SARS-CoV-2 (“COVID-19”) pandemic,
we are utilizing the Bruton’s tyrosine kinase (“BTK”) inhibitor (in-licensed from ACEA Therapeutics, Inc.) in a U.S. Phase II study of cytokine storm
associated with a COVID-19 infection and in a Phase II trial in Brazil in mild, moderate and severe COVID-19 patients, and we are also internally
developing potential coronavirus antiviral therapies and vaccines, including ACE-MABTM, COVIDTRAPTM, COVI-MABTM, COVI-GUARDTM, COVI-
SHIELDTM , COVI-AMG™ and T-VIVA-19TM; and diagnostic test solutions, including COVI-TRACK™, COVI-STIX™ and COVI-TRACE™.

With each of our clinical and pre-clinical programs, we aim to tailor our therapies to treat specific stages in the evolution of a disease, from

elimination, to equilibrium and escape. In addition, our objective is to focus on tumors that are resistant to current treatments and where we can design
focused trials based on a genetic signature or biomarker to ensure patients have the best chance of a durable and significant response. We have several
immuno-oncology programs that are in or near to entering the clinic. These include cellular therapies, oncolytic viruses (SeprehvecTM) and a palliative care
program targeted to treat intractable cancer pain. Our cellular therapy programs focus on CAR-T and DAR-T for adoptive cellular immunotherapy to treat
both solid and liquid tumors.

From the start of the COVID-19 pandemic, our mission has been to leverage our deep expertise in developing targeted antibodies for cancer
immunotherapy to create best-in-category treatments and diagnostics to ease suffering and assist in the global response to COVID-19. We have leveraged,
and continue to leverage, our G-MAB library and antibody development engineering capabilities to advance a number of promising diagnostics and
neutralizing antibody candidates to test and treat COVID-19 and the immune reactions associated with SARS-CoV-2 infection.

Our first generation SARS-CoV-2 neutralizing antibody was STI-1499 (COVI-GUARD™), which was engineered to prevent antibody dependent
enhancement. This antibody was then optimized to produce the highly potent STI-2020, which is currently being developed in two outpatient formations:
COVI-AMG (IV-push injection) and COVI-DROPS (nasal). COVI-AMG has been cleared by the U.S. Food and Drug Administration (“FDA”) for a Phase
I study of healthy volunteers, a Phase II study in outpatients with COVID-19 and a Phase II study in hospitalized patients with moderate or severe COVID-
19, and we are awaiting FDA clearance for a Phase I study of COVI-DROPS of healthy volunteers and patients with mild COVID-19. Sorrento also has
developed two promising potential rescue treatments with Abivertinib, an oral next generation dual EGFR/BTK inhibitor, to treat moderate to severe
hospitalized COVID-19 patients and COVI-MSC™, a human allogeneic adipose-derived mesenchymal stem cells for patients suffering from COVID-19-
induced acute respiratory distress (ARD). Both have been cleared by the FDA and are in Phase Ib clinical studies. We are also working with Brazilian
regulators (“ANVISA”) to conduct a COVID-19 study with Abivertinib and potentially with COVI-AMG TM. In pre-clinical development, we are rapidly
screening new neutralizing antibodies to address the multiple emerging variants of SARS-CoV-2 to potentially add to STI-2020 in a cocktail (COVI-
SHIELD™) and exploring novel mechanistic approaches such as soluble recombinant fusion protein traps (COVIDTRAPTM) to potentially inhibit the
binding of SARS-CoV-2’s spike protein with host ACE2 receptors, thereby potentially preventing viral cell entry.

In furtherance of our goal to develop products across the entire continuum of COVID-19 solutions, we are further developing a number of highly
sensitive and rapid diagnostic tests. COVI-STIX™ is a lateral flow antigen test that uses a proprietary platinum-based colloid and antibody combination,
resulting in high sensitivity and accuracy. This is a simple and rapid (15-minute) test with a shallow nasal swab and is designed for point-of-care and at-
home use. COVI-TRACK™ is a rapid SARS-CoV-2 IgG/IgM antibody

2

test kit intended for use initially in clinical laboratories and in point of care settings to quickly identify individuals with anti-SARS-CoV-2 antibodies post-
infection or post- vaccination. COVI-TRACE™ was licensed from Columbia University as a rapid single step on-site colorimetric detection test for SARS-
COV-2 genomic RNA from a saliva sample using targeted nucleic acid amplification for high throughput point-of-care situations.

We have reported early data from Phase I trials of our carcinoembryonic antigen (“CEA”)-directed CAR-T program. We have treated five patients

with stage 4, unresectable adenocarcinoma (four with pancreatic and one with colorectal cancer) and CEA-positive liver metastases with anti-CEA CAR-T.
We successfully submitted an Investigational New Drug application (“IND”) for anti-CD38 CAR-T for the treatment of refractory or relapsed multiple
myeloma (“RRMM”), obtained clearance from the FDA and commenced a human clinical trial for this indication in early 2018. We have dosed eleven
patients. We intend to close this study to further enrollment and start up a similar anti-CD38 CAR-T construct without the myc-tag (which cannot be used
in Europe), and to continue treating RRMM patients in a Phase Ib/IIa study, which will begin enrollment in the first quarter of 2021. We filed INDs for our
CD47 mAb and the first of our DAR-T platform product candidates in the first quarter of 2021.

Broadly speaking, we believe we are one of the world’s leading CAR-T and DAR-T companies today due to our investments in technology and
infrastructure, which have enabled significant progress in developing our next-generation non-viral, “off-the-shelf” allogeneic DAR-T solutions. With “off-
the-shelf” solutions, DAR-T therapy can truly become a drug product platform rather than a treatment procedure.

With respect to our ADC program, we began enrolling patients in the first quarter of 2021 in a Phase Ib ascending dose study of our CD38 ADC for

systemic Amyloid light-chain (“AL”) amyloidosis. Based upon our recently announced exclusive license from Mayo Clinic for its antibody-drug-
nanoparticle albumin-bound (“ADNAB”) platform, the next generation in ADC technology, we intend to file several INDs to treat various cancer targets.

Outside of immuno-oncology programs, as part of our global aim to provide a wide range of therapeutic products to meet underserved markets, we
have made investments in non-opioid pain management. These include resiniferatoxin (“RTX”), which is a non-opioid-based toxin that specifically targets
transient receptor potential vanilloid-1 (“TRPV1”) which, depending on the site of injection, can ablate, or destroy, nerves expressing TRPV1 or
temporarily defunctionalize them. TRPV1 is responsible for the noxious chronic and inflammatory pain signaling that occurs post injury or trauma, but
leaves other nerve functions intact. RTX has been granted orphan drug status for the treatment of intractable pain with end-stage cancer and two Phase Ib
trials (intrathecal and epidural routes) in that indication have or will soon be completed. A Phase Ib trial studying tolerance and efficacy of RTX for the
control of moderate to severe osteoarthritis knee pain was initiated in late 2018 and intermediate results have shown efficacy with no dose limiting
toxicities. The osteoarthritis trial enrolled the last patient in the first quarter of 2020, and we expect to release the final safety clinical data by the middle of
2021. We plan to start knee arthritis registrational trials after the completion of required preclinical studies.

Also, in this area, we have developed in-house and acquired proprietary technologies to responsibly develop next generation, branded

pharmaceutical products to better manage patients’ medical conditions, maximize the quality of life of patients and assist healthcare providers. The flagship
product of our majority-owned subsidiary, Scilex Pharmaceuticals Inc. (“Scilex Pharma”), ZTlido® (lidocaine topical system 1.8%) (“ZTlido”), is a next-
generation lidocaine delivery system, which was approved by the FDA for the treatment of postherpetic neuralgia, a severe neuropathic pain condition in
February 2018, and was commercially launched in October 2018. Scilex Pharma has now built a full commercial organization, which includes sales,
marketing, market access and medical affairs. ZTlido has demonstrated superior adhesion in comparative head-to-head studies as compared to Lidoderm
and is manufactured by our Japanese partner in their state-of-the-art manufacturing facility.

Our Strategy

Our primary goal is to leverage our fully human antibody development expertise to address significant unmet medical needs that can significantly

improve a patient’s quality of life.  In the face of the ongoing COVID-19 pandemic, we marshalled our resources to generate antibody-based treatments and
diagnostic initiatives for COVID-19 in addition to acquiring other treatment assets to treat the entire spectrum of COVID-19 infections, from outpatients
with mild infections, to hospitalized patients with moderate or severe infections.  Despite the COVID-19 pandemic, we continue to make progress in our
oncology programs and treatments for refractory chronic pain conditions, such as intractable pain due to advanced cancer or knee osteoarthritis.

3

Our core strategic objectives and resources are:

1. Using a deliberate process to optimize our lead product candidates to fill identified unmet needs and advance them rapidly into the clinic for

initiation of Phase I studies.  Once demonstrated to be safe and efficacious, we plan to continue to drive through later phase (II and III) studies toward a
new drug application (“NDA”) filing.  Early in this process, we evaluate each program for potential accelerated approval or breakthrough therapy
designation to fast-track development.

2. Collaborating with key opinion leaders and leading clinical and research institutes to enhance our clinical development plans and achieve our

goals.  We currently have such agreements in place with the Mayo Clinic, Karolinska Institute, The Scripps Research Institute (“TSRI”), the National
Institutes of Health (“NIH”) and Tufts Medical School, among others.

3. Having active programs that utilize our antibodies in CAR-T, DAR-T, our antibody-drug conjugate platform (using our covalent linker
technology), ADNAB platform, and our Sofusa® DoseConnect™ lymphatic delivery device to treat various oncology indications.  Additionally, we have
active programs to treat the spectrum of COVID-19 infections with our highly potent neutralizing antibodies (“nAbs”) to treat outpatients with mild
COVID-19 symptoms (IV COVI-AMG™ and intranasal COVI-DROPS™) and hospitalized patients with moderate infections (COVI-GUARD™),
abivertinib (Bruton’s tyrosine kinase; BTK inhibitor) and mesenchymal stem cells to treat severe COVID-19 with or without acute respiratory distress
syndrome. We are also planning to use our nAb, COVI-AMG™, paired with a DNA plasmid platform for intramuscular injection to induce one’s own body
to generate nAbs to fight COVID-19.  Finally, we continue to progress resiniferatoxin, an ultrapotent TRPV-1 agonist, into Phase III for the treatment of
intractable pain in advanced cancer and into a Phase II dose-ranging and proof-of-concept study in severe knee osteoarthritis.  Our subsidiary, Scilex
Holding, is completing its Phase III epidural approach to the treatment of lumbar radiculopathy.

4. Continuing, through our preclinical programs, to generate development candidates with exciting potential to meet unmet needs. We anticipate

generating data to support more than a dozen new INDs in 2021.  These include moving our checkpoint inhibitors from our core antibody portfolio into the
clinic with our strategic key opinion leaders and institutional partners. We will continue to develop our fully human monoclonal antibody (mAb) portfolio
for new ADCs and bispecific mAbs (“BsAbs”).  In addition, we expect to commence several clinical trials with the Sofusa® device to explore safety and
efficacy features of this innovative drug delivery technology.

5. Manufacturing our preclinical and clinical materials to support Phase I and II trials in-house. We have established quality control and quality

assurance programs to ensure that our products are produced under current good manufacturing practices (“cGMPs”), and other applicable domestic and
foreign regulations.

6. Continuing to explore strategic partnerships to share in the risk reward of our core franchises and to derive near term value from our non-core
programs. Our partnering objectives include generating revenue through license fees, milestone-related development fees and royalties as well as profit
shares or joint ventures to generate potential returns from our product candidates and technologies.

Segment Information

Effective January 1, 2019, we realigned our business into two new operating and reportable segments, Sorrento Therapeutics and Scilex.

Sorrento Therapeutics. The Sorrento Therapeutics segment is organized around our Immune-Oncology therapeutic area, leveraging our proprietary

G-MAB™ antibody library and targeted delivery modalities to generate the next generation of cancer therapeutics. These modalities include proprietary
CAR-T, DAR-T, ADCs as well as bispecific antibody approaches. Additionally, this segment also includes Sofusa®, a drug delivery technology that
delivers biologics directly into the lymphatic system to potentially achieve improved efficacy and fewer adverse effects than standard parenteral
immunotherapy, and RTX, which is a non-opioid-based neurotoxin currently in clinical trials for late stage cancer pain and moderate to severe osteoarthritis
of the knee pain.

Scilex. The Scilex segment is largely organized around our non-opioid pain management operations. Revenues from the Scilex segment are

exclusively derived from the sale of ZTlido.

Clinical Programs

G-MAB™: Fully Human Antibody Library Platform

Our G-MAB™ library, which forms the backbone of many of our product candidates, was initially invented by Henry Ji, Ph.D., our co-founder,

President and Chief Executive Officer. We believe our proprietary G-MAB™ library is one of the industry’s largest and most diverse fully human antibody
libraries, with an estimated one quadrillion unique antibodies available for drug discovery and development. We believe G-MAB™ may offer the following
advantages over competing antibody libraries:

•

•

G-MAB™ has been designed to provide a full spectrum of human immunoglobulin gene recombination in fully-human mAbs. Unlike
chimeric and humanization technologies, G-MAB™ has allowed the generation of antibodies with fully-human protein sequences without the
challenges and limitations of animal-to-human gene transfer procedures.

Because G-MAB™ represents an in vitro human mAb library technology, research suggests that it enables faster and cost-effective in vitro
screening of a large number of antigens. G-MAB™ is designed so that any antigen of interest can be investigated, with no dependence on the
successful induction of a host immune response against the antigen.

The following is a depiction of the types of fully human mAbs that we have derived from G-MAB™. It includes antibodies that bind to a wide
range of targets, from small molecular weight antigens to large protein complexes antigens, such as G-Protein Coupled Receptors (“GPCRs”), a
difficult class of antigens to raise therapeutics antibodies against.

Our objective is to leverage G-MAB™ to develop first in class or best in class antibody drug candidates that will possess greater efficacy and fewer
side effects as compared to existing drugs and develop them as novel monotherapies, ADCs (such as c-MET), components of bispecific antibodies, and as
part of our adoptive immunotherapy (CD38, BCMA), oncolytic virus program and intracellular targeting programs (STAT3, mutant KRAS).

To date, we have screened over 100 validated targets and generated a number of fully human antibodies against these targets which are at various
stages of development. These include PD-1, PD-L1, CD38, BCMA, CTLA-4, CD123, CD47, c-MET, VEGFR2, CCR2 and CD137 among others. Upon
the completion of preclinical studies, our objective is to, independently or in tandem with our strategic collaborators, file INDs for these product
candidates.

COVID-19 (SARS-CoV-2)

COVID-19 is a new pandemic disease caused by a single-stranded RNA virus termed SARS-CoV-2.  Infection with COVID-19 may cause severe

disease requiring hospitalization in up to a third of patients, with frequent progression to acute respiratory distress syndrome (“ARDS”) and a high
mortality rate. A virus-induced hyperinflammatory response or “cytokine storm” has been hypothesized to be a major contributor to ARDS through
modulation of pulmonary macrophages, dendritic cells and other immune cells.  Patients with COVID-19 may develop elevated blood levels of multiple
inflammatory cytokines and chemokines and those who are admitted to intensive care have even higher levels of these cytokines, which may indicate a far
worse outcome.

We have leveraged our expertise in producing fully-human monoclonal antibodies and our extensive G-MAB™ antibody library to develop potent
neutralizing antibodies directed to the spike protein of SARS-CoV-2 or COVID-19.  In addition, we have acquired assets that target the entire spectrum of
COVID-19 infections, from outpatients who are asymptomatic or with mild symptoms to hospitalized patients with moderate symptoms to patients with
severe or critical COVID-19 in intensive care units.  Paired with our highly sensitive and specific diagnostic tests for COVID-19, we have developed the
ability to diagnose early and treat every stage of this pandemic infection.

5

 
 
 
STI-2020 (COVI-AMG™) is the affinity-matured neutralizing antibody developed from STI-1499 (COVI-GUARD) which has been shown in vitro

to be effective against the original Wuhan, China COVID-19 strain and emerging strains, D614G and N439K.  STI-2020, formulated for intravenous
administration, blocks viral interactions with the ACE-2 receptor to prevent cell entry and replication and was engineered to lack any antibody-dependent
enhancement (“ADE”) and tissue cross-reactivity (including possible hypersensitivity) neither of which has been observed in in vitro or in vivo preclinical
studies.  In the Syrian Golden hamster model, intravenous STI-2020 rapidly reverses COVID-19 infection and clears viral particles from lung tissues.  After
a successful IND submission, intravenous STI-2020 (administered as a slow intravenous push, not as an infusion) is currently in the clinic enrolling a
healthy subject study to obtain initial safety and pharmacokinetic data before the intended studies in outpatients with mild COVID-19 infections in the
United States, Brazil and Mexico.

STI-2099 (COVI-DROPS™) is STI-2020 formulated for intranasal delivery.  The neutralizing potency of STI-2020 lends itself to intranasal
delivery, which may be an effective way of rapidly reducing infectivity and clearing viral burden from the nasopharynx and lung airways.  STI-2099 may
be a preferred treatment for children who may not be willing to receive an injection. With IND clearance expected in the first quarter of 2021, we plan on
conducting healthy subject studies comparing intranasal STI-2099 alone or in combination with intravenous STI-2020 for an “outside/inside” approach to
reduce infectivity and treat the systemic infection in late first quarter of 2021.  This first study will be conducted as a randomized double-blind, placebo-
controlled study at the Dahms Clinical Research Unit at the University Hospitals, Case Western University.  After verifying safety, we expect to rapidly
move into a Phase Ib study and Phase II studies enrolling outpatients who are asymptomatic or have mild COVID-19 symptoms and using intranasal STI-
2099 alone or in combination with intravenous STI-2020.  Studies are planned for the United States, Brazil and Mexico.

STI-5656 (abivertinib maleate) is a potent, small molecule third-generation tyrosine kinase inhibitor (“TKI”) of epidermal growth factor receptor

(“EGFR”) and, importantly, also a BTK receptor.  It inhibits the gatekeeper mutation of EGFR; T790M, as well as the common activating mutations
(L858R, 19del), and has minimal inhibitory activity against the wild type (“WT”) receptor, contributing to its observed safety.  Additionally, STI-5656
irreversibly binds to the BTK receptor at nanomolar potency, preventing the phosphorylation of the receptor and has shown potent immunomodulatory
activities by inhibiting key pro-inflammatory cytokine production, including IL-1beta, IL-6 and TNF-alpha, all of which are correlated with higher
morbidity and mortality in ARDS and “cytokine storm” due to COVID-19 infections.  STI-5656 is currently enrolling subjects in a Phase II study of
intensive care unit subjects with severe or critical COVID-19 in the United States.  We also are starting up a larger Phase II study in Brazil.  

STI-8282 Mesenchymal Stem Cells: After acquiring an allogeneic culture-expanded adipose-derived mesenchymal stem cell (“MSC”) asset from

Personalized Stem Cells, we transitioned the open IND and are currently enrolling a Phase Ib study of subjects with severe COVID-19 infections
complicated by impending ARDS who will each receive three infusions of STI-8282 MSCs in hopes of preventing the pulmonary fibrosis, edema,
inflammation and other comorbid processes accompanying respiratory failure.  This study is enrolling at a single California site, but will be expanded to
other sites in the United States and Brazil.

STI-8472 (COVI-GeneMAb™): Finally, while not directly a “treatment” for COVID-19, the acquisition of SmartPharm Therapeutics, Inc. in

September 2020 gave us the ability to use non-viral DNA and RNA gene delivery platforms to create a gene-encoded therapeutic product candidate using
our STI-2020 neutralizing antibody.  With this combination, an intramuscular injection can cause the person’s own body to produce the neutralizing
antibody for possibly months instead of having to rely on intermittent injections of externally manufactured antibodies, such as STI-2020.  STI-8472
(COVI-GeneMAb™) is the combination of the non-viral DNA plasmid with gene-encoded STI-2020.  We are in the process of completing the IND-
enabling preclinical and chemistry, manufacturing and controls steps necessary to file an IND in the first quarter of 2021. We envision a combination of an
STI-2020 injection to “treat” and STI-8472 to “prevent” reinfection in those positive for COVID-19 or in subjects negative for COVID-19, along with STI-
8472 to prevent infection. This may be a valuable option for those who refuse to be vaccinated for health or other reasons.  This program received approved
funding from the Defense Advanced Research Projects Agency (“DARPA”), an advanced-technology branch of the U.S. Department of Defense.

Anti-CD38 CAR-T Program

Chimeric antigen receptors (“CARs”) have been created for commercial and clinical development programs.  The architecture of the CAR consists

of a single fusion protein with several functional components: a single-chain variable fragment (“scFv”) derived from an anti-tumor antibody fused to a
structural support segment, a transmembrane portion, and one or more intracellular signaling domains.  Potential drawbacks of the CAR technology are the
use of scFv that often possess inferior biophysical stability and biochemical functionality compared to their parental antibodies.

The membrane glycoprotein CD38 is widely found on the surface of lymphoid and myeloid lineages including B, T and NK cells, but absent from

most mature resting lymphocytes with the notable exception of terminally differentiated plasma cells. Because CD38 is highly expressed on multiple
myeloma cells, it represents a valuable and validated therapeutic target against myeloma. Multiple myeloma is a hematologic malignancy in which clonal
plasma cells accumulate in the bone marrow or extramedullary sites

and give rise to clinical complications such as painful, lytic bone lesions, hypercalcemia, renal impairment, cytopenias, and symptomatic plasmacytomas.

STI-2798 and STI-5171 (anti-CD38 CAR-T): Our proprietary, second generation anti-CD38 CAR-T therapy is being developed for the treatment
of RRMM.  Our anti-CD38 CAR-T is based on a fully human anti-CD38 monoclonal antibody derived from our G-MAB™ antibody library.  We recently
completed a Phase Ib ascending dose safety study of STI-5171 which began in 2018 with the initial anti-CD38 CAR-T platform.  While long-term follow
up is continuing, in the last two dose cohorts (106 or 107 cells/kg body weight), we achieved a 50% overall response rate.  We improved on the CAR-T
construct by removing the “myc tag” (which cannot be used in Europe) CAR-T product candidate (STI-2798) and made changes to the lymphodepletion
protocol in hopes of improving long-term cell persistence.  After a successful IND submission for STI-2798, our new anti-CD38 CAR-T (-myc), we are
activating sites and will continue to enroll subjects with RRMM in the coming year.  

Anti-CD38 KOKI DAR-T Program

We are addressing the potential weaknesses of CAR constructs while building on the clinical experience generated within our current CAR-T

programs with the design of dimeric antigen receptors (“DARs”) based on the complete antigen-binding fragment (“Fab”) of the parental antibody.  It is
generally accepted that Fabs more closely mimic the functional and biophysical properties of natural antibodies.  Utilizing the same antibody binding
domain sequence, we have compared CAR constructs with a scFv binding domain to a DAR construct with a Fab or two chain binding domain.  Our data
showed that the DAR-T cells exhibited a higher functional activity with regards to cytokine production, and cytotoxicity against target-expressing tumor
cells compared to CAR-T cells. In preclinical mouse models, the DAR-T cells demonstrated increased anti-tumor potency as well.  We are currently
applying our DAR technology to our ongoing cell therapy programs for multiple hematological and solid tumor indications, including but not limited to
multiple myeloma, lymphoma, liver cancer, sarcoma, pancreatic cancer and glioma.

STI-1492, an allogeneic non-viral anti-CD38 A2 KOKI DAR-T cell agent (second generation anti-CD38 “knock-out knock-in” dimeric antigen

receptor 4-1BBζ - engineered T cells), is completing FDA-required steps before beginning our clinical enrollment.  STI-1492 consists of allogeneic donor
T cells that are engineered to express an anti-CD38 antigen receptor for the treatment of patients with RRMM.  The DAR consists of a fragment antigen-
binding variable region (Fab) instead of the scFv utilized by CARs. During the production of STI-1492, there is a “knock-in” of the DAR into the T-cell
receptor (“TCR”) alpha constant region (“TRAC”) gene. The TCR alpha is simultaneously inactivated (“knock-out”) by this DAR knock-in process,
allowing allogeneic T cells to be administered therapeutically without the development of graft versus host disease.  The anti-CD38 A2 DAR vector is
integrated into the TCR locus by CRISPR/Cas9 gene-editing methods instead of by a lentivirus/retrovirus.  In addition, STI-1492 utilizes a 4-1BB co-
stimulatory domain. The anti-CD38 DAR design is associated with enhanced cytotoxic activity, longer persistence and possibly less toxicity compared with
the anti-CD38 CAR design in preclinical studies.  The ability to administer this agent as modified allogeneic T cells allows STI-1492 to be stored as an off-
the-shelf agent that eliminates the need for leukapheresis and the treatment delay for the manufacturing process for each individual patient associated with
autologous cellular therapy.

Our KOKI technology may offer several potential benefits over existing virus-based technology using transgene-encoding lentivirus, retrovirus or

adeno-associated virus to introduce antigen receptor constructs into healthy donor (allogeneic) or cancer patient (autologous) T cells.  These potential
advantages of our non-viral KOKI technology include:

•

•

•

site-specific integration of transgenes into a pre-selected locus in the T cell genome

streamlined method for transgene construct production without need for laborious and time-consuming virus production, release and
validation processes, resulting in a shorter research and development timelines for IND-enabling activities and

applicability to both autologous and allogeneic cellular therapies

We intend to use our G- MAB™ library to generate a number of monoclonal antibodies that can be used with our KOKI DAR-T platform to target a
number of difficult to treat cancers.

Anti-CD38 Antibody-Drug Conjugate (ADC) Program

AL amyloidosis is an incurable disease that is characterized by a clonal population of bone marrow plasma cells that produces a monoclonal light

chain immunoglobulin.  The clonal plasma cells often make up less than 10% of the nucleated cells in the bone marrow in patients with AL
amyloidosis.  The light chain immunoglobulin is of a ĸ or λ type and is produced as either an intact molecule or a fragment.  The light chain protein
produced by the dysfunctional plasma cells associated with AL amyloidosis is misfolded, forming β-pleated sheets that deposit in tissues in the form of
amyloid fibrils.  The insoluble tissue protein deposits interfere with organ function and the soluble circulating light chains may be toxic to organs as
well.  The clinical features of AL amyloidosis depend on which organs are involved and may include restrictive cardiomyopathy, nephrotic syndrome,
hepatic dysfunction, peripheral and/or autonomic neuropathy and signs or symptoms of an atypical multiple myeloma.

STI-6129 ADC is composed of a human monoclonal anti-CD38 A2 antibody (STI-5171) covalently bound by a chemical linker to a dolastatin
tubulin inhibitor chemotherapeutic derivative (duostatin 5.2).  STI-5171 was generated from Sorrento’s proprietary antibody library. The binding affinity of
STI-5171 to CD38 is comparable to that of daratumumab (Sorrento data on file). The STI-6129 ADC is produced by conjugation of the drug-linker-
duostatin moiety to the parent STI-5171 monoclonal antibody.  The heavy chain of the STI-5171 parent antibody included in the STI-6129 ADC has been
modified by a C246→S mutation that substitutes a serine amino acid for cysteine. This substitution results in an antibody with 3 inter-chain disulfide bonds
instead of the 4 disulfide bonds present in wild type IgG1 antibodies and provides an ADC with drug to antibody ratio of 3 (Sorrento data on file). Upon
binding to CD38 target cell surface antigen, the STI-6129 ADC is internalized by the cell and undergoes lysosomal degradation resulting in the release of
the duostatin 5.2 chemotherapeutic agent.  This targeted delivery of potent chemotherapeutic agents is designed to enhance activity against the aberrant
plasma cells in AL amyloidosis, minimize toxicity in normal tissues, and provide sustained delivery of the chemotherapy over time.  The proprietary
covalent linker technology reduces premature release of the duostatin which may reduce ocular toxicity and other adverse events.  After a successful IND
submission, STI-6129 is currently enrolling patients in an ascending dose study to identify the maximum tolerated dose to be used for the treatment of AL
amyloidosis.  Once a recommended Phase II dose is identified, an expansion cohort will be enrolled.  Additionally, we are partnering with Columbia
University in New York City to assess STI-6129 in the treatment of RRMM.

Anti-CD47 Fully Human Monoclonal Antibody Program (STI-6643)

Several studies have described the role of cluster of differentiation 47/Signal regulatory protein-alpha (“CD47/SIRPα”) interaction in regulating

macrophage-mediated phagocytosis and dendritic cell-mediated cross-priming of T cells.  CD47 is a ubiquitously expressed immuno-regulatory
glycoprotein (also known as integrin-associated protein) of the immunoglobulin superfamily best known for its so called ‘don’t eat me’ function that
prevents phagocytic removal of healthy cells by the body’s immune system.  Many cancers present high levels of this signal on their cell surface, thereby
disrupting anti-cancer immune responses.  Given CD47’s essential role as a negative checkpoint for innate immunity and subsequent adaptive immunity,
the CD47-SIRPα axis has been explored as a new target for cancer immunotherapy and its disruption has demonstrated great therapeutic promise in
reestablishing antitumor activity in vivo.  However, significant anemia and thrombocytopenia has plagued early product candidates (e.g., Hu5F9-G4 or
magrolimab, a humanized IgG4 monoclonal antibody) due to CD47 expression on normal cells, particularly aging red blood cells which may lose this
‘marker of self’ becoming susceptible to clearance by splenic macrophages.  This major ‘on-target’ dose limiting toxicity was seen with magrolimab in
preclinical studies and required complicated priming methodologies to reduce this risk.

STI-6643 is our novel fully human CD47 monoclonal antibody that blocks CD47/SIRPα to promote in vitro anti-tumor phagocytic activity.  When

incubated with human peripheral blood mononuclear cells in a mixed lymphocyte reaction assay, STI-6643 demonstrated minimal T, B or NK cell
depletion as opposed to reference clones (prepared based on sequence analysis) which could result in improved efficacy by preserving the infiltrating anti-
tumor immune cells.  Additionally, STI-6643 showed 15- to 30-fold reduction in observed hemagglutination in human and cynomolgus monkey red blood
cells, respectively, and despite its high binding to canine red blood cells, it showed reduced hemagglutination in comparison to magrolimab (clone prepared
based on the sequence analysis).  An IND submission is pending clearance for STI-6643 in the treatment of a variety of advanced cancers. We hope to
begin enrollment in the first quarter of 2021.

Antibody-Drug Nanoparticle Albumin Bound (ADNAB) Platform

We are currently involved in a partnership with Mayo Clinic Rochester, with Dr. Svetomir Markovic, to use the nanoparticle human serum albumin
bound paclitaxel (or other chemotherapeutic agents) platform to bind various monoclonal antibodies to the external surface of the albumin micelles to form
stable complexes that can be designed to target specific cancers for delivery directly to the tumor microenvironment.  This partnership would leverage our
existing antibody library, including PD-1, PD-L1, CD38, BCMA, CTLA-4, CD123, CD47, c-MET, VEGFR2, CCR2 and CD137, among others, to create
ADNAB products that may enhance tumor response.  The first programs (B cell lymphomas, melanoma and gynecological cancers) are already ongoing
under an investigator-initiated IND that we will support moving forward and when initial proof of concept is available, we intend to transfer the IND and
offer the product candidate to other sites around the country.

Sofusa® Lymphatic Delivery System (S-LDS)

Sofusa is a novel technology platform designed for targeted drug delivery to lymphatics vessels and lymph nodes.  Abnormal immune system
function is implicated in many conditions such as cancer and autoimmune diseases (e.g., Rheumatoid Arthritis, Multiple Sclerosis and Psoriasis).  Sofusa’s
proprietary nanotopography draped microneedles have been shown to reversibly open tight junctions in the skin and facilitate paracellular and transcellular
transport across the epidermis.  In pre-clinical biodistribution studies, this proprietary microneedle and microfluidics system has consistently demonstrated
the ability to deliver over 40-fold in drug concentration to lymph nodes (with lower drug concentration in systemic organs) when compared to traditional
intravenous (“IV”) and subcutaneous (“SC”) injections. After a 1-hour administration with Sofusa, elevated lymph node concentrations are sustained

8

beyond 36 hours. Multiple pharmacodynamic models confirm that increased exposure to drug targets in the lymphatics has potential to improve clinical
response, potentially at significantly lower doses vs IV or SC administration.

Phase I clinical safety studies have now been completed for a large molecule (etanercept) and for a small molecule (sumatriptan).  We have filed two

INDs and are authorized to proceed with our first human efficacy studies with an anti-TNFα in Rheumatoid Arthritis and with a checkpoint inhibitor in
oncology. This checkpoint study is designed to evaluate the safety and efficacy of a Sofusa anti-PD1 antibody in patients with Cutaneous T-Cell
Lymphoma. In this pilot study, we will evaluate the feasibility of Sofusa delivery in patients with skin cancers accessible to biopsies for intensive
biomarker assessments. These trials will help assess whether the principles of better efficacy and safety seen in lymphatic administration of drugs in animal
models can be replicated in patients. If the Sofusa Lymphatic Delivery System is successful in the clinic, the commercial Sofusa® DoseDisc™ wearable
device may offer not only the potential for both improved clinical response, but also a more convenient dosing alternative to traditional SC injections or IV
infusions for patients.

Based upon the Sofusa core microneedle technology, we have also developed the Sofusa MuVaxx™ device for the administration of small volume

peptides and vaccines.  The skin (rich in dendritic cells) and lymph nodes are the primary organs for generating both humoral immunity (IgG and IgM) and
cellular immunity (memory T-Cells) for long-term protection.  In a pre-clinical COVID-19 vaccine study, the Sofusa device resulted in 10-40X higher T-
Cell response versus IM and intradermal injections. The Sofusa MuVaxx device is designed to be a simple low-cost attachment to a standard syringe for
rapid large-scale deployment of our vaccine candidates.

Oncolytic Virus Program (Seprehvir® and Seprehvec®)

We previously completed two trials using Herpes simplex virus lacking infected cell protein 34.5 (“HSV1716”) or Seprehvir to treat solid pediatric

or young adult non-central nervous system tumors or malignant pleural mesothelioma with intratumoral, intravenous of intrapleural administration.  A
second-generation product, Seprehvec, is a platform that can generate a number of possible product candidates and the first, STI-1386, is gearing up for an
IND submission early in 2021 with targeted cancers still to be finalized.

Resiniferatoxin (“RTX”) Programs

RTX is a naturally occurring compound obtained from cactus-like succulents of the Euphorbia species. An ultra-potent TRPV1 agonist, RTX

belongs to the same general TRPV1 family as capsaicin, the active ingredient in red chili peppers. As an agonist, RTX produces a sustained opening of
calcium channels expressed on neurons, either in the end-terminals or cell bodies, of C-fibers or A-delta fibers.  The effect from this sustained calcium
influx depends on the location that RTX is injected.  When injected peripherally near end-terminals (for example intra-articularly), a sustained
defunctionalization or desensitization occurs resulting in reduction in noxious chronic pain symptoms that can last for months.  When injected neuraxially
(intrathecally or epidurally) rapid programmed cell death of TRPV1-expressing neurons targeted by the RTX injection can produce long-lasting
improvement in noxious chronic pain that has been refractory to treatment (e.g., cancer related pain). RTX does not interact with and leaves unaffected non-
TRPV1-expressing nerves (touch, motor control and position sense).

An investigator-sponsored Phase I clinical trial of intrathecal RTX has been ongoing at the NIH under a Cooperative Research and Development

Agreement. To date, 14 patients with terminal cancer pain have been treated intrathecally at the NIH.

A Phase Ib clinical trial with epidural RTX was completed in 2020 in 17 subjects with intractable pain due to advanced cancer. No dose limiting

toxicity was observed at doses up to 25 mcg RTX and RTX demonstrated promising efficacy in relieving intractable pain associated with advanced
cancer.  A Phase II/III study was submitted to the IND in December 2020 and will begin enrolling early in 2021.

Another Phase Ib clinical trial with intra-articular RTX administration for moderate-to-severe osteoarthritis of the knee was completed with no dose

limiting toxicities at any of the administered doses. 94 patients were enrolled at RTX doses from 5 mcg to 25 mcg; 40 subjects enrolled in the placebo-
controlled ascending dose portion of the study, 38 subjects received 12.5 mcg and 16 subjects received 25 mcg.  The preliminary efficacy results in this
study show promising evidence of a significant improvement lasting well beyond 6 months.  These preliminary results will need to be documented in a
Phase II proof-of-concept study comparing several RTX doses against placebo, which is planned for early 2021.

Scilex Holding

Scilex Holding is focused on cost-effectively developing and commercializing non-opioid therapies that will provide safe and substantial, localized

pain relief for large market opportunities. The following chart illustrates the current product and product candidates for which Scilex Holding has
worldwide commercialization rights, except with respect to Japan for ZTlido and SP-103:

10

 
ZTlido

ZTlido is a lidocaine topical system approved for the relief of pain associated with post-herpetic neuralgia (“PHN”). PHN is a chronic neuropathic

pain syndrome that results as a complication following an infection of herpes zoster, also known as shingles. Herpes zoster symptoms typically resolve
after a few weeks, but the pain caused by the nerve injury can persist for months to years in the affected area. ZTlido is designed as a lighter, thinner
product which has improved adhesion relative to Lidoderm (lidocaine patch 5%), while providing a bioequivalent delivery of lidocaine in an efficient drug
delivery system.

We launched ZTlido in October 2018 with support from an integrated commercial organization using a dedicated contract sales force and our own
sales management, marketing and managed care capabilities. We market ZTlido through a dedicated sales force of 60 individuals, targeting approximately
10,000 primary care physicians, pain specialists, neurologists and palliative care physicians. We are utilizing a multi-channel marketing strategy to expand
awareness and utilization of ZTlido.

SEMDEXA

SEMDEXA is a Phase III product candidate we are developing to be an injectable viscous gel formulation of a widely used corticosteroid designed

to address the serious risks posed by off-label epidural steroid injections, or ESIs, for the treatment of sciatica, a pathology of low back pain. We believe
SEMDEXA, if successfully developed, has the potential to reduce the disability related to sciatica and help delay or avoid spine surgery. SEMDEXA has
been granted fast track designation by the FDA and, if approved, could become the only FDA-approved alternative to off-label ESIs, which are
administered over 10 million times annually in the United States. We are currently evaluating SEMDEXA in a pivotal Phase III Corticosteroid Lumbar
Epidural Analgesia for Radiculopathy trial, which is designed to evaluate the safety and efficacy in the proposed indication. We expect top-line results from
the study in the second half of 2021, and if results are positive, we intend to submit a request to the FDA for breakthrough designation.

SP-103

SP-103 is an investigational, non-aqueous lidocaine topical system undergoing clinical development in low back pain conditions. SP-103 builds on

the learnings from ZTlido because both products share a similar adhesive drug delivery formulation and manufacturing technology. If approved, we believe
that SP-103 could become the first-in-class lidocaine topical product for low back pain indications. All current uses of topical lidocaine products for low
back pain are off-label. SP-103 has three times the drug load of ZTlido (108 mg versus 36 mg) in the adhesive system to potentially deliver threefold level
of the drug within a targeted area, still with the convenience of a single topical system. Additionally, SP-103 is designed to deliver a localized dose of
lidocaine that is threefold greater than any lidocaine topical product that we are aware of either on the market or in development. If approved, we believe
SP-103 may be able to address the limitations of prescription lidocaine patches in treating low back pain by delivering a higher dose of lidocaine to the
application site. We expect the Phase II trial to commence in the second half of 2021.

Patents and Other Proprietary Rights

We are able to protect our technology from unauthorized use by third parties only to the extent that it is covered by valid and enforceable patents, is

Kimberly-Clark Worldwide, Inc. (“KCCW” and together with KCC and KCCGS, “Kimberly-Clark”) in July 2018 as a novel technology
platform designed to deliver large molecules, such as antibodies, directly into lymphatic capillaries and tumor draining lymph nodes. This
micro-epidermal infusion system features a proprietary microneedle array and microfluidics reservoir. The Sofusa technology is the subject of
multiple granted and pending applications with potential patent coverage to at least 2040.

Certain factors can either extend patent terms or provide other forms of exclusivity (e.g., data exclusivity) for varying periods depending on the date
of patent filing, date of grant or the legal term of a patent in the various jurisdictions in which patent protection is obtained. The actual protection afforded
by a patent, which can vary from country to country, also depends upon the type of patent, the scope of claim coverage and the availability of legal
remedies in the particular country.

While trade secret protection is an essential element of our business and we have taken security measures to protect our proprietary information and
trade secrets, we cannot guarantee that our unpatented proprietary technology will afford us significant commercial protection. We seek to protect our trade
secrets by entering into confidentiality agreements with third parties, employees and consultants. Our employees and consultants also sign agreements
requiring that they assign to us their interest in any intellectual property arising from their work for us. All employees sign an agreement not to engage in
any conflicting employment or activity during their employment with us and not to disclose or misuse our confidential information. However, it is possible
that these agreements may be breached or invalidated and, if so, there may not be an adequate corrective remedy. Accordingly, we cannot guarantee that
employees, consultants or third parties will not breach the confidentiality provisions in our contracts, infringe or misappropriate our trade secrets or other
proprietary rights, or that measures we are taking to protect our proprietary rights will be adequate.

In the future, third parties may file claims asserting that our technologies or products infringe on their intellectual property. We cannot predict
whether third parties will assert such claims against us or against the licensors of technology licensed to us, or whether those claims will harm our business.
If we are forced to defend ourselves against such claims, whether they are with or without merit and whether they are resolved in favor of, or against, our
licensors or us, we may face costly litigation and the diversion of management’s attention and resources. As a result of such disputes, we may have to
develop costly non-infringing technology or enter into licensing agreements. These agreements, if necessary, may be unavailable on terms acceptable to us,
or at all.

Competition

The biotechnology and pharmaceutical industries are characterized by rapidly advancing technologies, intense competition, a strong emphasis on
proprietary products and intellectual property. While we believe that our scientific knowledge, technology and development experience provide us with
competitive advantages, we face potential competition from many different sources, including major pharmaceutical, specialty pharmaceutical and
biotechnology companies, academic institutions, governmental agencies and public and private research institutions, some or all of which may have greater
access to capital or resources than we do. For any products that we may ultimately commercialize, not only will we compete with any existing therapies
and those therapies currently in development, we will have to compete with new therapies that may become available in the future.

We expect that the market will become increasingly competitive in the future. Many of our competitors, either alone or together with their

collaborative partners, operate larger research and development programs, and have substantially greater commercial and financial resources than we do, as
well as significantly greater experience in: developing product candidates and technologies, undertaking preclinical studies and clinical trials, obtaining
FDA and other regulatory approvals of product candidates, formulating and manufacturing product candidates and launching, marketing and selling
product candidates. As a result, these companies may obtain marketing approval more rapidly than we are able and may be more effective in developing,
selling and marketing their products.

Immunotherapy

Immunotherapy is an active area of research and several immune-related products have been identified in recent years that modulate the immune

system. Many of these products utilize dendritic cells, a form of immune cell that presents cancer target peptides to T cells and that can in turn result in T-
cell activation. More recently, bispecific antibodies and checkpoint inhibitors (for instance PD‑1/PD-L1 antibodies) have been identified as having utility in
the treatment of cancer. Bi-specific antibodies commonly target both the cancer peptide and the TCR, thus bringing both cancer cells and T cells into close
proximity to maximize the chance of TCR binding and hence an immune response to the cancer cells. Checkpoint inhibitors on the other hand, work by
targeting receptors that inhibit T-cell effectiveness and proliferation and thereby essentially activate T cells. Other immunotherapies that are being actively
investigated include: antibody drug complexes, TCR-mimic antibodies, oncolytic viruses, cancer vaccines.

We are aware of companies developing therapies in various areas related to our specific research and development programs. Specifically, there are
a growing number of pharmaceutical, biotechnology, and academic institutions researching and developing autologous and allogeneic CAR-T therapies in
both the solid and liquid tumor setting. These CAR-T cell therapies are at a variety of stages of preclinical, clinical development and approval. Such
therapies are directed towards a broad target spectrum, including but not limited to: DLL3, EGFR, GD2, HER-2, IL13rα2, Lewis Y, L1-CAM, Mesothelin,
MUC16, PSCA, PSMA and ROR1. The two approved CAR-T therapies both target CD19.

RTX

The pain management field in particular is a growing industry due to increased attention on opioid usage for pain, which has created a rapidly

emerging market and has fueled an increased interest in opioid alternatives. The rise of various small and early-stage companies in the non-opioid pain
management field may also prove to be significant competitors, particularly if they enter into collaborative arrangements with large, established companies.

13

COVID-19 Product Candidates

Neutralizing antibodies (nAbs): Sorrento has several nAbs either in development or in the clinic.  These nAbs are directed against the COVID-19

spike protein.  The lead nAb, STI-2020, has been shown to be effective in preclinical studies against various escape mutations (D614G, N439K, and B117
variants) as part of Sorrento’s ongoing surveillance program.  Two companies (Regeneron and Lilly) have obtained EUA clearance for their nAbs
(Regeneron’s casirivimab/imdevimab cocktail and Lilly’s bamlanivimab). There are several other companies which have nAbs in early development. In
addition, companies which are involved in vaccine development are indirect competitors in this space, although the vaccines known to be in development
are not nAbs-based.

Bruton’s Tyrosine Kinase Inhibitors (BTKI): Sorrento currently is in mid-Phase 2 trials for abivertinib, its dual EGFR/BTKI, to treat acute
respiratory distress due (ARD) to COVID-19. There are several other BTKIs approved for oncology conditions that could theoretically be used to treat
COVID-19-induced ARD.  Acalabrutinib (Calquence™) was used in two Phase 2 studies but failed to meet its primary endpoint.

Adipose-derived mesenchymal stem cells (AdMSCs): We are currently enrolling a Phase 1b study treating COVID-19-induced ARD and ARD
syndrome (ARDS). There are a large number of companies and universities exploring various MSCs (adipose, bone marrow, cord blood, umbilical and
other sources) in Phase 1 and 2 studies to treat moderate to severe COVID-19.

Scilex

ZTlido and our product candidate, SP-103, if approved, face and will likely face competition from prescription and generic topical lidocaine patches,
including Lidoderm and generic lidocaine patches manufactured by Teva, Mylan and Par Pharmaceutical, Inc. Additionally, SP-103, if approved, will likely
compete with various opioid pain medications, nonsteroidal anti-inflammatory drugs (“NSAIDs”), muscle relaxants, antidepressants and anticonvulsants,
particularly as we seek approval for the treatment of chronic low back pain.

SEMDEXA, if approved, has the potential to become the first FDA-approved epidural steroid product for the treatment of sciatica. While there are

currently no FDA approved ESIs indicated for the treatment of sciatica, we are aware of certain non-steroid product candidates in development. For
example, Sollis Therapeutics, Inc. is developing its product candidate, a non-opioid, non-steroid clonidine micropellet to be administered through epidural
injection, which is currently in Phase III development. SEMDEXA, if approved, will compete with various opioid pain medications, NSAIDs, muscle
relaxants, antidepressants, anticonvulsants and surgical procedures. Procedures may include nerve blocks and transcutaneous electrical nerve stimulations.
We may also face indirect competition from the off-label and unapproved use of branded and generic injectable steroids.

The key competitive factors affecting the success of ZTlido, SEMDEXA and SP-103 are likely to be their efficacy, durability, safety, price and the

availability of reimbursement from government and other third-party payors.

Government Regulation

Government authorities in the U.S. (including federal, state and local authorities) and in other countries extensively regulate, among other things, the

manufacturing, research and clinical development, marketing, labeling and packaging, storage, distribution, post-approval monitoring and reporting,
advertising and promotion, export and import of pharmaceutical products, such as those we are developing. The process of obtaining regulatory approvals
and the subsequent compliance with appropriate federal, state, local and foreign statutes and regulations require the expenditure of substantial time and
financial resources. Moreover, failure to comply with applicable regulatory requirements may result in, among other things, warning letters, clinical holds,
civil or criminal penalties, recall or seizure of products, injunction, disbarment, partial or total suspension of production or withdrawal of the product from
the market. Any agency or judicial enforcement action could have a material adverse effect on us.

U.S. Government Regulations

In the U.S., the FDA regulates drugs under the Federal Food, Drug, and Cosmetic Act (“FDCA”) and its implementing regulations. Drugs are also
subject to other federal, state and local statutes and regulations. The process required by the FDA before product candidates may be marketed in the U.S.
generally involves the following:

•

completion of extensive preclinical laboratory tests and preclinical animal studies, all performed in accordance with the FDA’s Good
Laboratory Practice (“GLP”) regulations. Preclinical testing generally includes evaluation of our product candidates in the laboratory or in
animals to characterize the product and determine safety and efficacy;

14

 
•

•

•

•

•

•

•

•

submission to the FDA of an IND, which must become effective before human clinical trials may begin and must be updated annually;

performance of adequate and well-controlled human clinical trials to establish the safety and efficacy of the product candidate for each
proposed indication;

submission to the FDA of a Biologics License Application (“BLA”) or a NDA after completion of all pivotal clinical trials;

a determination by the FDA within 60 days of its receipt of a BLA or an NDA to file the BLA or NDA for review;

satisfactory completion of an FDA pre-approval inspection of the manufacturing facilities at which the active pharmaceutical ingredient
(“API”) and finished drug product are produced and tested to assess compliance with cGMP regulations;

satisfactory completion of an FDA pre-approval inspection of one or more of the clinical sites at which the clinical trials were conducted;

at the discretion of the FDA, a public Advisory Committee Meeting where the data is reviewed by experts who discuss the data and give their
opinion (which the FDA is not obliged to follow) of the adequacy of the data to support an approval; and

FDA review and approval of a BLA or an NDA prior to any commercial marketing or sale of the drug in the U.S.

In addition, we are subject to regulation under state, federal, and international laws and regulations regarding occupational safety, laboratory
practices, import and export of materials and products, environmental protection and the use and handling of hazardous substance control, and other
regulations. Our clinical trial and research and development activities involve the controlled use of hazardous materials and chemical compounds. Although
we believe that our safety procedures for handling and disposing of such materials comply with the standards prescribed by state and federal regulations,
the risk of accidental contamination or injury from these materials cannot be completely eliminated. In the event of such an accident, we could be held
liable for any damages that result and any such liability could exceed our financial resources. In addition, disposal of radioactive materials used in our
clinical trials and research efforts may only be made at approved facilities. We believe that we are in material compliance with all applicable laws and
regulations including those relating to the handling and disposal of hazardous and toxic waste.

An IND is a request for authorization from the FDA to administer an investigational drug product to humans. The central focus of an IND
submission is on the general investigational plan and the protocol(s) for human studies. The IND also includes results of animal studies or other human
studies, as appropriate, as well as manufacturing information, analytical data and any available clinical data or literature to support the use of the
investigational new drug. An IND must become effective before human clinical trials may begin. An IND will automatically become effective 30 days after
receipt by the FDA, unless before that time the FDA raises concerns or questions related to the proposed clinical trials. In such a case, the IND may be
placed on clinical hold and the IND sponsor and the FDA must resolve any outstanding concerns or questions before clinical trials can begin. Accordingly,
submission of an IND may or may not result in the FDA allowing clinical trials to commence.

Clinical trials involve the administration of the investigational drug to human subjects under the supervision of qualified investigators in accordance

with Good Clinical Practices (“GCPs”), which include the requirement that all research subjects provide their informed consent for their participation in
any clinical trial. Clinical trials are conducted under protocols detailing, among other things, the objectives of the study, the parameters to be used in
monitoring safety, and the efficacy criteria to be evaluated. A protocol for each clinical trial and any subsequent protocol amendments must be submitted to
the FDA as part of the IND. Additionally, approval must also be obtained from each clinical trial site’s institutional review board (“IRB”) before the trials
may be initiated, and the IRB must monitor the study until completed. There are also requirements governing the reporting of ongoing clinical trials and
clinical trial results to public registries.

The pre-approval clinical investigation of a drug is generally divided into three phases (the numbers of subjects/patients are approximate and vary

from indication to indication). Although the phases are usually conducted sequentially, they may overlap or be combined. The three phases of an
investigation are as follows:

•

Phase I. Phase I includes the initial introduction of an investigational new drug into humans. Phase I clinical trials are typically closely
monitored and may be conducted in patients with the target disease or condition or in healthy volunteers. These studies are designed to
evaluate the safety, dosage tolerance, metabolism and pharmacologic actions of the investigational drug in humans, the side effects associated
with increasing doses, and if possible, to gain early evidence on effectiveness. During Phase I clinical trials, sufficient information about the
investigational drug’s pharmacokinetics and pharmacological effects may be obtained to permit the design of well-controlled and
scientifically valid Phase II clinical trials. The total number of participants included in Phase I clinical trials varies, but is generally in the
range of 20 to 80.

15

 
 
 
 
 
 
 
 
 
•

•

Phase II. Phase II includes controlled clinical trials conducted to preliminarily or further evaluate the effectiveness of the investigational drug
for a particular indication(s) in patients with the disease or condition under study, to determine dosage tolerance and optimal dosage, and to
identify possible adverse side effects and safety risks associated with the drug. Phase II clinical trials are typically well-controlled, closely
monitored, and conducted in a limited patient population, usually involving no more than several hundred participants.

Phase III. Phase III clinical trials are generally controlled clinical trials conducted in an expanded patient population generally at
geographically dispersed clinical trial sites. They are performed after preliminary evidence suggesting effectiveness of the drug has been
obtained, and are intended to further evaluate dosage, clinical effectiveness and safety, to establish the overall benefit-risk relationship of the
investigational drug product, and to provide an adequate basis for product approval. Phase III clinical trials usually involve several hundred to
several thousand participants. In general, two Phase III trials are needed for an approval.

A pivotal trial is a clinical trial that adequately meets regulatory agency requirements for the evaluation of a drug candidate’s efficacy and safety
such that it can be used to justify the approval of the product. Generally, pivotal trials are also Phase III trials but may be Phase II trials if the trial design
provides a well-controlled and reliable assessment of clinical benefit, particularly in situations where there is an unmet medical need.

The FDA, the IRB or the clinical trial sponsor may suspend or terminate a clinical trial at any time on various grounds, including a finding that the

research subjects are being exposed to an unacceptable health risk. Additionally, some clinical trials are overseen by an independent group of qualified
experts organized by the clinical trial sponsor, known as a data safety monitoring board or committee. This group provides authorization for whether or not
a trial may move forward at designated check points based on access to certain data from the study. We may also suspend or terminate a clinical trial based
on evolving business objectives and/or competitive climate.

Assuming successful completion of all required testing in accordance with all applicable regulatory requirements, detailed investigational drug

product information is submitted to the FDA in the form of an NDA requesting approval to market the product for one or more indications.

The application includes all relevant data available from pertinent preclinical and clinical trials, including negative or ambiguous results as well as

positive findings, together with detailed information relating to the product’s chemistry, manufacturing, controls and proposed labeling, among other things.
Data can come from company-sponsored clinical trials intended to test the safety and effectiveness of a use of a product, or from a number of alternative
sources, including studies initiated by investigators. To support marketing approval, the data submitted must be sufficient in quality and quantity to
establish the safety and effectiveness of the investigational drug product to the satisfaction of the FDA.

Once the BLA or NDA submission has been accepted for filing, the FDA’s goal is to review applications within ten months of submission or, if the

application relates to an unmet medical need in a serious or life-threatening indication, six months from submission. The review process is often
significantly extended by FDA requests for additional information or clarification. The FDA may refer the application to an advisory committee for review,
evaluation and recommendation as to whether the application should be approved. The FDA is not bound by the recommendation of an advisory
committee, but it typically follows such recommendations.

During the evaluation of the BLA or NDA, the FDA conducts inspections of manufacturing facilities where the drug product and/or its API will be

produced and some of the clinical sites that conducted the trials, and it may issue an approval letter or a Complete Response Letter. An approval letter
authorizes commercial marketing of the drug with specific prescribing information for specific indications. A Complete Response Letter indicates that the
review cycle of the application is complete and the application is not ready for approval. A Complete Response Letter may require additional clinical data,
an additional pivotal Phase III clinical trial(s), and/or other significant, expensive and time-consuming requirements related to clinical trials, preclinical
studies or manufacturing. Even if such additional information is submitted, the FDA may ultimately decide that the BLA or NDA does not satisfy the
criteria for approval. The FDA could also approve the BLA or NDA with a Risk Evaluation and Mitigation Strategies (“REMS”) plan to mitigate risks,
which could include medication guides, physician communication plans, or elements to assure safe use, such as restricted distribution methods, patient
registries and other risk minimization tools. The FDA also may condition approval on, among other things, changes to proposed labeling, development of
adequate controls and specifications, or a commitment to conduct one or more post-market studies or clinical trials. Such post-market testing may include
Phase IV clinical trials and surveillance to further assess and monitor the product’s safety and effectiveness after commercialization. Regulatory approval
of oncology products often requires that patients in clinical trials be followed for long periods to determine the overall survival benefit of the drug.

After regulatory approval of a drug product is obtained, we are required to comply with a number of post-approval requirements. As a holder of an

approved BLA or NDA, we would be required to report, among other things, certain adverse reactions

16

 
 
and production problems to the FDA, to provide updated safety and efficacy information, and to comply with requirements concerning advertising and
promotional labeling for any of our products. Also, quality control and manufacturing procedures must continue to conform to cGMP after approval to
ensure and preserve the long term stability of the drug product. The FDA periodically (about every two years) inspects manufacturing facilities to assess
compliance with cGMP, which imposes extensive procedural, substantive and record keeping requirements. In addition, changes to the manufacturing
process are strictly regulated, and, depending on the significance of the change, may 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 us and any
third-party manufacturers that we may decide to use. Accordingly, manufacturers must continue to expend time, money and effort in the area of production
and quality control to maintain compliance with cGMP and other aspects of regulatory compliance.

We rely, and expect to continue to rely, on third parties for the production, distribution, shipping and storage of clinical and commercial quantities of

our product candidates. Future FDA and state inspections may identify compliance issues at our facilities or at the facilities of our contract manufacturers
that may disrupt production or distribution or require substantial resources to correct. In addition, discovery of previously unknown problems with a
product or the failure to comply with applicable requirements may result in restrictions on a product, manufacturer or holder of an approved BLA or NDA,
including withdrawal or recall of the product from the market or other voluntary, FDA-initiated or judicial action that could delay or prohibit further
marketing. Newly discovered or developed safety or effectiveness data may require changes to a product’s approved labeling, including the addition of new
warnings and contraindications, and also may require the implementation of other risk management measures. Also, new government requirements,
including those resulting from new legislation, may be established, or the FDA’s policies may change, which could delay or prevent regulatory approval of
our product candidates under development.

Europe/Rest of World Government Regulations

In addition to regulations in the U.S., we will be subject to a variety of regulations in other jurisdictions governing, among other things, clinical

trials and any commercial sales and distribution of our products.

Whether or not we obtain FDA approval for a product, we must obtain the requisite approvals from regulatory authorities in foreign countries prior

to the commencement of clinical trials or marketing of the product in those countries. Certain countries outside of the U.S. have a similar process that
requires the submission of a clinical trial application much like the IND prior to the commencement of human clinical trials. In Europe, for example, a
clinical trial application (“CTA”) must be submitted to each country’s national health authority and an independent ethics committee, much like the FDA
and IRB, respectively. Once the CTA is approved in accordance with a country’s requirements, clinical trial development may proceed.

The requirements and process governing the conduct of clinical trials, product licensing, pricing and reimbursement vary from country to country. In

all cases, the clinical trials are conducted in accordance with GCP and the applicable regulatory requirements and the ethical principles that have their
origin in the Declaration of Helsinki.

To obtain regulatory approval of an investigational drug under European Union regulatory systems, we must submit a marketing authorization
application. The application used to file the NDA in the U.S. is similar to that required in Europe, with the exception of, among other things, country-
specific document requirements. For other countries outside of the European Union, such as countries in Eastern Europe, Latin America or Asia, the
requirements governing the conduct of clinical trials, product licensing, pricing and reimbursement vary from country to country. In all cases, again, the
clinical trials are conducted in accordance with GCP and the applicable regulatory requirements and the ethical principles that have their origin in the
Declaration of Helsinki.

If we fail to comply with applicable foreign regulatory requirements, we may be subject to, among other things, fines, suspension or withdrawal of

regulatory approvals, product recalls, seizure of products, operating restrictions and criminal prosecution.

Available Special Regulatory Procedures

Formal Meetings

We can engage and seek guidance from health authorities relating to the development and review of investigational drugs, as well as marketing

applications. In the U.S., there are different types of official meetings that may occur between us and the FDA. Each meeting type is subject to different
procedures. Conclusions and agreements from each of these meetings are captured in the official final meeting minutes issued by the FDA. Meetings with
the FDA are free.

The European Medicines Agency (“EMA”) also provides the opportunity for dialogue with us. This is usually done in the form of Scientific Advice,

which is given by the Scientific Advice Working Party of the Committee for Medicinal Products for Human Use (“CHMP”). A fee is incurred with each
Scientific Advice meeting.

17

Advice from either the FDA or EMA is typically provided based on specific questions concerning, for example, quality (chemistry, manufacturing

and controls testing), nonclinical testing and clinical trials and pharmaco-vigilance plans and risk-management programs. Such advice is not legally binding
on the sponsor. To obtain binding commitments from health authorities in the U.S. and the European Union, Special Protocol Assessment (“SPA”) or
Protocol Assistance procedures are available. An SPA is an evaluation by the FDA of a protocol with the goal of reaching an agreement with the sponsor
that the protocol design, clinical endpoints and statistical analyses are acceptable to support regulatory approval of the product candidate with respect to
effectiveness in the indication studied. The FDA’s agreement to an SPA is binding upon the FDA except in limited circumstances, such as if the FDA
identifies a substantial scientific issue essential to determining the safety or effectiveness of the product after clinical trials begin, or if the trial sponsor fails
to follow the protocol that was agreed upon with the FDA. There is no guarantee that a trial will ultimately be adequate to support an approval even if the
trial is subject to an SPA.

Orphan Drug Designation

The FDA may grant orphan drug designation to drugs intended to treat a rare disease or condition that affects fewer than 200,000 individuals in the
U.S., or, if it affects more than 200,000 individuals in the U.S., there is no reasonable expectation that the cost of developing and making the drug for this
type of disease or condition will be recovered from sales in the U.S. In the European Union, the EMA’s Committee for Orphan Medicinal Products
(“COMP”) grants orphan drug designation to promote the development of products that are intended for the diagnosis, prevention or treatment of a life-
threatening or chronically debilitating condition affecting not more than 5 in 10,000 persons in the European Union Community. Additionally, designation
is granted for products intended for the diagnosis, prevention or treatment of a life-threatening, seriously debilitating or serious and chronic condition and
when, without incentives, it is unlikely that sales of the drug in the European Union would be sufficient to justify the necessary investment in developing
the drug or biological product.  

In the U.S., orphan drug designation entitles a party to financial incentives such as opportunities for grant funding towards clinical trial costs, tax

advantages and user-fee waivers. In addition, if a product receives the first FDA approval for the indication for which it has orphan designation, the product
is entitled to orphan drug exclusivity, which means the FDA may not approve any other application to market the same drug for the same indication for a
period of 7 years, except in limited circumstances, such as a showing of clinical superiority over the product with orphan exclusivity.

In the European Union, orphan drug designation also entitles a party to financial incentives such as reduction of fees or fee waivers and 10 years of
market exclusivity is granted following drug or biological product approval. This period may be reduced to 6 years if the orphan drug designation criteria
are no longer met, including where it is shown that the product is sufficiently profitable not to justify maintenance of market exclusivity.

Orphan drug designation must be requested before submitting an application for marketing approval. Orphan drug designation does not convey any

advantage in, or shorten the duration of, the regulatory review and approval process.

Authorization Procedures in the European Union

Medicines can be authorized in the European Union by using either the centralized authorization procedure or national authorization procedures.

•

•

•

•

Centralized procedure. The EMA implemented the centralized procedure for the approval of human medicines to facilitate marketing
authorizations that are valid throughout the European Union. This procedure results in a single marketing authorization issued by the EMA
that is valid across the European Union, as well as Iceland, Liechtenstein and Norway. The centralized procedure is compulsory for human
medicines that are: derived from biotechnology processes, such as genetic engineering, contain a new active substance indicated for the
treatment of certain diseases, such as HIV/AIDS, cancer, diabetes, neurodegenerative disorders or autoimmune diseases and other immune
dysfunctions, and officially designated orphan medicines.

For medicines that do not fall within these categories, an applicant has the option of submitting an application for a centralized marketing
authorization to the EMA, as long as the medicine concerned is a significant therapeutic, scientific or technical innovation, or if its
authorization would be in the interest of public health.

National authorization procedures. There are also two other possible routes to authorize medicinal products in several countries, which are
available for investigational drug products that fall outside the scope of the centralized procedure:

Decentralized procedure. Using the decentralized procedure, an applicant may apply for simultaneous authorization in more than one
European Union country of medicinal products that have not yet been authorized in any European Union country and that do not fall within
the mandatory scope of the centralized procedure.

18

 
 
 
 
•

Mutual recognition procedure. In the mutual recognition procedure, a medicine is first authorized in one European Union Member State, in
accordance with the national procedures of that country. Following this, further marketing authorizations can be sought from other European
Union countries in a procedure whereby the countries concerned agree to recognize the validity of the original, national marketing
authorization.

Priority Review/Standard Review (U.S.) and Accelerated Review (European Union)

Based on results of the Phase III clinical trial(s) submitted in a BLA or NDA, upon the request of an applicant, the FDA may grant the BLA or NDA

a priority review designation, which sets the target date for FDA action on the application at six months. Priority review is granted where preliminary
estimates indicate that a product, if approved, has the potential to provide a safe and effective therapy where no satisfactory alternative therapy exists, or a
significant improvement compared to marketed products is possible. If criteria are not met for priority review, the BLA or NDA is subject to the standard
FDA review period of 10 months. Priority review designation does not change the scientific/medical standard for approval or the quality of evidence
necessary to support approval.

Under the Centralized Procedure in the European Union, the maximum timeframe for the evaluation of a marketing authorization application is 210

days (excluding clock stops, when additional written or oral information is to be provided by the applicant in response to questions asked by the CHMP).
Accelerated evaluation might be granted by the CHMP in exceptional cases, when a medicinal product is expected to be of a major public health interest,
defined by three cumulative criteria: the seriousness of the disease (e.g., heavy disabling or life-threatening diseases) to be treated; the absence or
insufficiency of an appropriate alternative therapeutic approach; and anticipation of high therapeutic benefit. In this circumstance, EMA ensures that the
opinion of the CHMP is given within 150 days, excluding clock stops.

There can be no assurance that we or any of our partners would be able to satisfy one or more of these requirements to conduct preclinical or clinical

trials or receive any regulatory approvals.

Pharmaceutical Coverage, Pricing and Reimbursement

Significant uncertainty exists as to the coverage and reimbursement status of any drug products for which we obtain regulatory approval. In the U.S.
and markets in other countries, sales of any products for which we receive regulatory approval for commercial sale will depend in part on the availability of
reimbursement from third-party payors. Third-party payors include government health administrative authorities, managed care providers, private health
insurers and other organizations. The process for determining whether a payor will provide coverage for a drug product may be separate from the process
for setting the price or reimbursement rate that the payor will pay for the drug product. Third-party payors may limit coverage to specific drug products on
an approved list, or formulary, which might not include all of the FDA-approved drugs for a particular indication. Third-party payors are increasingly
challenging the price and examining the medical necessity and cost-effectiveness of medical products and services, in addition to their safety and efficacy.
We may need to conduct expensive pharmacoeconomic studies in order to demonstrate the medical necessity and cost-effectiveness of our products, in
addition to the costs required to obtain FDA approvals. Our product candidates may not be considered medically necessary or cost-effective. A payor’s
decision to provide coverage for a drug product does not imply that an adequate reimbursement rate will be approved. Adequate third-party reimbursement
may not be available to enable us to maintain price levels sufficient to realize an appropriate return on our investment in product development.

In 2003, the U.S. government enacted legislation providing a partial prescription drug benefit for Medicare beneficiaries, which became effective at

the beginning of 2006. Government payment for some of the costs of prescription drugs may increase demand for any products for which we receive
marketing approval. However, to obtain payments under this program, we would be required to sell products to Medicare recipients through prescription
drug plans operating pursuant to this legislation. These plans will likely negotiate discounted prices for our products. Further, the Patient Protection and
Affordable Care Act, as amended by the Health Care and Education Reconciliation Act (collectively, the “Healthcare Reform Law”), substantially changed
the way healthcare is financed in the U.S. by both government and private insurers. Among other cost containment measures, the Healthcare Reform Law
established:

•

•

•

An annual, nondeductible fee on any entity that manufactures or imports certain branded prescription drugs and biologic agents;

A new Medicare Part D coverage gap discount program, in which pharmaceutical manufacturers who wish to have their drugs covered under
Part D must offer discounts to eligible beneficiaries during their coverage gap period (the “donut hole”); and

A new formula that increases the rebates a manufacturer must pay under the Medicaid Drug Rebate Program.

19

 
 
 
 
We expect that federal, state and local governments in the U.S. will continue to consider legislation to limit the growth of healthcare costs, including

the cost of prescription drugs. Future legislation could limit payments for pharmaceuticals such as the drug candidates that we are developing.

Different pricing and reimbursement schemes exist in other countries. In the European Union, governments influence the price of pharmaceutical
products through their pricing and reimbursement rules and control of national health care systems that fund a large part of the cost of those products to
consumers. Some jurisdictions operate positive and negative list systems under which products may only be marketed once a reimbursement price has been
agreed. To obtain reimbursement or pricing approval, some of these countries may require the completion of clinical trials that compare the cost-
effectiveness of a particular product candidate to currently available therapies. Other member states allow companies to fix their own prices for medicines,
but monitor and control company profits. The downward pressure on health care costs in general, particularly prescription drugs, has become very intense.
As a result, increasingly high barriers are being erected to the entry of new products. In addition, in some countries, cross-border imports from low-priced
markets exert a commercial pressure on pricing within a country.

The marketability of any products for which we receive regulatory approval for commercial sale may suffer if the government and third-party
payors fail to provide adequate coverage and reimbursement. In addition, an increasing emphasis on managed care in the U.S. has increased and we expect
will continue to increase the pressure on pharmaceutical pricing. 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 we receive regulatory approval, less favorable coverage
policies and reimbursement rates may be implemented in the future.

Other Healthcare Laws and Compliance Requirements

If we obtain regulatory approval for any of our product candidates, we may be subject to various federal and state laws targeting fraud and abuse in
the healthcare industry. For example, in the U.S., there are federal and state anti-kickback laws that prohibit the payment or receipt of kickbacks, bribes or
other remuneration intended to induce the purchase or recommendation of healthcare products and services or reward past purchases or recommendations.
Violations of these laws can lead to civil and criminal penalties, including fines, imprisonment and exclusion from participation in federal healthcare
programs.

The federal Anti-Kickback Statute prohibits persons from knowingly and willfully soliciting, receiving, offering or paying remuneration, directly or

indirectly, to induce either the referral of an individual, or the furnishing, recommending, or arranging for a good or service, for which payment may be
made under a federal healthcare program, such as the Medicare and Medicaid programs. The reach of the Anti-Kickback Statute was broadened by the
Healthcare Reform Law, which, among other things, amended the intent requirement of the federal Anti-Kickback Statute and the applicable criminal
healthcare fraud statutes contained within 42 U.S.C. § 1320a-7b, effective March 23, 2010. Pursuant to the statutory amendment, a person or entity no
longer needs to have actual knowledge of this statute or specific intent to violate it in order to have committed a violation. In addition, the government may
assert that a claim including items or services resulting from a violation of the federal Anti-Kickback Statute constitutes a false or fraudulent claim for
purposes of the civil False Claims Act (discussed below) or the civil monetary penalties statute. Many states have adopted laws similar to the federal Anti-
Kickback Statute, some of which apply to the referral of patients for healthcare items or services reimbursed by any source, not only the Medicare and
Medicaid programs.

The federal False Claims Act imposes liability on any person who, among other things, knowingly presents, or causes to be presented, a false or
fraudulent claim for payment by a federal healthcare program. The “qui tam” provisions of the False Claims Act allow a private individual to bring civil
actions on behalf of the federal government alleging that the defendant has submitted a false claim to the federal government, and to share in any monetary
recovery. In addition, various states have enacted false claims laws analogous to the False Claims Act. Many of these state laws apply where a claim is
submitted to any third-party payer and not merely a federal healthcare program. When an entity is determined to have violated the False Claims Act, it may
be required to pay up to three times the actual damages sustained by the government, plus civil penalties of $11,463 to $22,927 (each subject to adjustment
for inflation) for each separate false claim.

Also, the Health Insurance Portability and Accountability Act of 1996 (“HIPAA”) created several new federal crimes, including healthcare fraud,

and false statements relating to healthcare matters. The health care fraud statute prohibits knowingly and willfully executing a scheme to defraud any health
care benefit program, including private third-party payers. The false statements statute prohibits knowingly and willfully falsifying, concealing or covering
up a material fact or making any materially false, fictitious or fraudulent statement in connection with the delivery of or payment for health care benefits,
items or services.

In addition, we may be subject to, or our marketing activities may be limited by HIPAA, as amended by the Health Information Technology for

Economic and Clinical Health Act and its implementing regulations, which established uniform standards for certain “covered entities” (healthcare
providers, health plans and healthcare clearinghouses) and their business associates governing the conduct of certain electronic healthcare transactions and
protecting the security and privacy of protected health information.

Antibody Clinical Development

We currently focus our research efforts primarily in the identification and isolation of human antibody drug candidates and further characterize these

antibody candidates in in vitro and in vivo functional testing. Due to our limited financial resources, we intend to actively seek product development and
commercialization partners from the biopharmaceutical industry to help us advance the clinical development of select product candidates.

Marketing and Sales

With the exception of our subsidiary, Scilex Holding, we currently do not have any sales capabilities. We intend to license to, or enter into strategic
alliances with, larger companies in the biopharmaceutical businesses or use the services of contract sales organizations (“CROs”), which are equipped to,
market and/or sell our products, if any, through their well-developed marketing and sales teams and distribution networks. We intend to license some or all
of our worldwide patent rights to more than one third party to achieve the fullest development, marketing and distribution of any products we develop.

Manufacturing and Raw Materials

We currently manufacture the majority of our preclinical and clinical materials in-house, and use contract manufacturers for the manufacture of

some of our product candidates. We may or may not manufacture the products we develop, if any. As of December 31, 2020, our ZTlido product is
manufactured by ITOCHU CHEMICAL FRONTIER Corporation. Our internal manufacturing and contract manufacturers are subject to extensive
governmental regulation. Regulatory authorities in our markets require that pharmaceutical products be manufactured, packaged and labeled in conformity
with cGMPs. We have established a quality control and quality assurance program, which includes a set of standard operating procedures and specifications
designed to ensure that our products are manufactured in accordance with cGMPs, and other applicable domestic and foreign regulations.

Employees

As of December 31, 2020, we had 502 employees and 29 consultants and advisors. A significant number of our management and our other

employees and consultants have worked or consulted with pharmaceutical, biotechnology or medical product companies. While we have been successful in
attracting skilled and experienced scientific personnel, there can be no assurance that we will be able to attract or retain the necessary qualified employees
and/or consultants in the future.

None of our employees are covered by collective bargaining agreements and we consider relations with our employees to be good. We focus on

identifying, recruiting, developing and retaining a team of highly talented and motivated employees. The principal purposes of our equity and cash
incentive plans are to attract, retain and reward personnel through the granting of stock-based and cash-based compensation awards, as well providing our
employees with the opportunity to participate in our employee stock purchase plan, in order to increase stockholder value and the success of our company
by motivating such individuals to perform to the best of their abilities and achieve our objectives. The success of our business is fundamentally connected
to the well-being, health and safety of our employees. In an effort to protect the health and safety of our employees, we took proactive action from the
earliest signs of the COVID-19 outbreak, which included implementing social distancing policies at our facilities, facilitating remote working arrangements
and imposing employee travel restrictions.

Corporate Information

On September 21, 2009, QuikByte Software, Inc., a Colorado corporation and shell company (“QuikByte”), consummated its acquisition of

Sorrento Therapeutics, Inc., a Delaware corporation and private concern (“STI”), in a reverse merger (the “Merger”).

We were originally incorporated as San Diego Antibody Company in California in 2006 and were renamed “Sorrento Therapeutics, Inc.” and
reincorporated in Delaware in 2009, prior to the Merger. QuikByte was originally incorporated in Colorado in 1989. Following the Merger, on December 4,
2009, QuikByte reincorporated under the laws of the State of Delaware (the “Reincorporation”). Immediately following the Reincorporation, on
December 4, 2009, we merged with and into QuikByte, the separate corporate existence of STI ceased and QuikByte continued as the surviving corporation
(the “Roll-Up Merger”). Pursuant to the certificate of merger filed in connection with the Roll-Up Merger, QuikByte’s name was changed from “QuikByte
Software, Inc.” to “Sorrento Therapeutics, Inc.”

Item 1A.Risk Factors.  

Risk Factor Summary 

Below is a summary of the principal factors that make an investment in our common stock speculative or risky. This summary does not address all of the
risks that we face. Additional discussion of the risks summarized in this risk factor summary, and other risks that we face, can be found below and should
be carefully considered, together with other information in this Annual Report on Form 10-K and our other filings with the Securities and Exchange
Commission before making investment decisions regarding our common stock.

We are a clinical stage company subject to significant risks and uncertainties, including the risk that we or our partners may never develop,
obtain regulatory approval or market any of our product candidates or generate product related revenues.

We have incurred significant losses since inception and anticipate that we will incur continued losses for the foreseeable future.

We will require substantial additional funding, which may not be available to us on acceptable terms, or at all. If we fail to raise the necessary
additional capital, we may be unable to complete the development and commercialization of our product candidates or continue our
development programs.

We are heavily dependent on the success of our technologies and product candidates, and we cannot give any assurance that our product
candidates will receive regulatory approval, which is necessary before they can be commercialized.

The regulatory approval processes of the FDA, the MHRA, the EMA and comparable foreign authorities are lengthy, time consuming and
inherently unpredictable, and if we are ultimately unable to obtain regulatory approval for our product candidates, our business will be
substantially harmed.

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

Our product candidates may cause undesirable side effects or have other properties that could delay or prevent their regulatory approval, limit
the commercial profile of an approved label, or result in significant negative consequences following marketing approval, if any.

We rely on third parties to conduct our preclinical and clinical trials. If these third parties do not successfully perform their contractual legal
and regulatory duties or meet expected deadlines, we may not be able to obtain regulatory approval for or commercialize our product
candidates and our business could be substantially harmed.

We may not be able to manufacture our products or product candidates in commercial quantities, which would prevent us from
commercializing our products and product candidates.

With respect to ZTlido and any of our product candidates for which we may receive regulatory approvals, we will be subject to ongoing
obligations and continued regulatory review, which may result in significant additional expense. Additionally, our product candidates, if
approved, could be subject to labeling and other restrictions and market withdrawal and we may be subject to penalties if we fail to comply
with regulatory requirements or experience unanticipated problems with our products.

Our failure to successfully discover, acquire, develop and market additional product candidates or approved products would impair our ability
to grow.

Our commercial success depends upon us attaining significant market acceptance of our product candidates, if approved for sale, among
physicians, patients, healthcare payors and major operators of cancer and other clinics.

Reimbursement may be limited or unavailable in certain market segments for our product candidates, which could make it difficult for us to
sell our products profitably.

Price controls may be imposed, which may adversely affect our future profitability.

Our collaborations depend upon the efforts of third parties to fund and manage the development of many of our potential product candidates,
and failure of those third-party collaborators to assist or share in the costs of product development could materially harm our business,
financial condition and results of operations.

If we are unable to retain and recruit qualified scientists and advisors, or if any of our key executives, key employees or key consultants
discontinues his or her employment or consulting relationship with us, it may delay our development efforts or otherwise harm our business.

We will need to increase the size of our company and may not effectively manage our growth.

Drug development involves a lengthy and expensive process with an uncertain outcome, and results of earlier studies and trials may not be
predictive of future trial results.

There can be no assurance that the product candidates we are developing for the detection and treatment of COVID-19 will be granted an
Emergency Use Authorization by the FDA. If no Emergency Use Authorization is granted or, once granted, it is terminated, we will be unable
to sell our product candidates in the near future and will be required to pursue the drug approval process, which is lengthy and expensive.

Interim “top-line” and preliminary data from our clinical trials that we announce or publish from time to time may change as more patient
data become available and are subject to audit and verification procedures that could result in material changes in the final data.

We are involved, and may become involved in the future, in disputes and other legal or regulatory proceedings that, if adversely decided or
settled, could materially and adversely affect our business, financial condition and results of operations.

We have acquired, and plan to continue to acquire, assets, businesses and technologies and may fail to realize the anticipated benefits of the
acquisitions, and acquisitions can be costly and dilutive.

Any acquisitions we make could disrupt our business and seriously harm our financial condition.

Our long-term success depends on intellectual property protection; if our intellectual property rights are invalidated or circumvented, our
business will be adversely affected.

If any of our trade secrets, know-how or other proprietary information is disclosed, the value of our trade secrets, know-how and other
proprietary rights would be significantly impaired and our business and competitive position would suffer.

Claims that we infringe upon the rights of third parties may give rise to costly and lengthy litigation, and we could be prevented from selling
products, forced to pay damages, and defend against litigation.

If we breach any of the agreements under which we license commercialization rights to our product candidates from third parties, we could
lose license rights that are important to our business.

From time to time we may need to license patents, intellectual property and proprietary technologies from third parties, which may be
difficult or expensive to obtain.

The market price of our common stock may fluctuate significantly, and investors in our common stock may lose all or a part of their
investment.

Our strategic investments may result in losses.

Risks Related to Our Financial Position and Capital Requirements

We are a clinical stage company subject to significant risks and uncertainties, including the risk that we or our partners may never develop, obtain
regulatory approval or market any of our product candidates or generate product related revenues.

We are primarily a clinical stage biotechnology company that began operating and commenced research and development activities in 2009.
Pharmaceutical product development is a highly speculative undertaking and involves a substantial degree of risk. There is no assurance that our libraries
of fully-human mAbs or any of our other product candidates in development will be suitable for diagnostic or therapeutic use, or that we will be able to
identify and isolate therapeutic product candidates, or develop, market and commercialize these candidates. We do not expect any of our product candidates
in development, including, but not limited to, our fully-human mAbs, biosimilars/biobetters, fully human anti-PD-L1 and anti-PD-1 checkpoint inhibitors
derived from our proprietary G-MAB™ library platform, antibody drug conjugates (“ADCs”), bispecific antibodies (“BsAbs”), as well as Chimeric
Antigen Receptor T Cells (“CAR-T”) and Dimeric Antigen Receptor T Cells (“DAR-T”) for adoptive cellular immunotherapy, resiniferatoxin (“RTX”),
higher strength lidocaine topical system (SP-103) and non-opioid corticosteroid formulated as a viscous gel injection (SP-102) (“SEMDEXATM”) to be
commercially available for a few years, if at all. Additionally, our COVID-19 related product candidates, including STI-1499 (neutralizing antibody;
COVI-GUARDTM), STI-2020 (affinity matured neutralizing antibody; COVI-AMGTM), neutralizing antibody cocktail (COVI-SHIELDTM), STI-5656
(Abivertinib), STI-4398 (ACE2 receptor decoy protein; COVIDTRAPTM), STI-3333 (targeted virus vaccine; T-VIVA-19TM), STI-2030 (Salicyn-30),
serological IgM/IgG antibody diagnostic test (COVI-TRACKTM), saliva-based antigen diagnostic test for SARS-CoV-2 (COVI-TRACETM) and lateral
flow viral antigen diagnostic test for SARS-CoV-2 (COVI-STIXTM), are subject to uncertainties relating to product development, regulatory approval and
commercialization, and further risks based on the constantly evolving situation affecting the United States and the international community. Even if we are
able to commercialize our product candidates, there is no assurance that these candidates would generate revenues or that any revenues generated would be
sufficient for us to become profitable or thereafter maintain profitability.

24

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
We do not have many products that are approved for commercial sale and therefore do not expect to generate any revenues from product sales from
most of our product candidates in the foreseeable future, if ever.

We have generated limited product related revenues to date, and, with the exception of ZTlido® (lidocaine topical system 1.8%) (“ZTlido”), do not
expect to generate any such revenues for at least the next several years, if at all. To obtain revenues from sales of our product candidates, we must succeed,
either alone or with third parties, in developing, obtaining regulatory approval for, manufacturing and marketing products with commercial potential. We
may never succeed in these activities, and we may not generate sufficient revenues to continue our business operations or achieve profitability.

We have incurred significant losses since inception and anticipate that we will incur continued losses for the foreseeable future.

As of December 31, 2020 and 2019, we had an accumulated deficit of $958.3 million and $659.8 million, respectively. We continue to incur
significant research and development and other expenses related to our ongoing operations. We have incurred operating losses since our inception, expect
to continue to incur significant operating losses for the foreseeable future, and we expect these losses to increase as we: (i) advance RTX, STI-6129 (anti-
CD38 ADC), SP-103, SEMDEXATM and our other product candidates, including our COVID-19 related product candidates, STI-1499 (COVI-
GUARDTM) and STI-5656 (Abivertinib), into further clinical trials and pursue other development, acquire, develop and manufacture clinical trial materials
and increase other regulatory operating activities, (ii) conduct further studies for our preclinical COVID-19 related product candidates, including STI-2020
(COVI-AMGTM), neutralizing antibody cocktail (COVI-SHIELDTM), STI-4398 (COVIDTRAPTM) and STI-2030 (Salicyn-30), to advance to clinical
trials and seek regulatory approval; (iii) incur incremental expenses associated with our efforts to further advance a number of potential product candidates
into preclinical development activities, (iv) continue to identify and advance a number of fully human therapeutic antibody and ADC preclinical product
candidates, (v) incur higher salary, lab supply and infrastructure costs incurred in connection with supporting all of our programs, (vi) invest in our joint
ventures, collaborations or other third party agreements, (vii) incur expenses in conjunction with defending and enforcing our rights in various litigation
matters, (viii) expand our corporate, development and manufacturing infrastructure, and (ix) support our subsidiaries, including Scilex Holding Company
(“Scilex Holding”) and SmartPharm Therapeutics, Inc., in their clinical trial, development and commercialization efforts. As such, we are subject to all
risks incidental to the development of new biopharmaceutical products and related companion diagnostics, and we may encounter unforeseen expenses,
difficulties, complications, delays and other unknown factors that may adversely affect our business. Our prior losses, combined with expected future
losses, have had and will continue to have an adverse effect on our stockholders’ equity and working capital.

We will require substantial additional funding, which may not be available to us on acceptable terms, or at all. If we fail to raise the necessary
additional capital, we may be unable to complete the development and commercialization of our product candidates or continue our development
programs.

Our operations have consumed substantial amounts of cash since inception. We expect to significantly increase our spending to advance the

preclinical and clinical development of our product candidates and launch and commercialize any product candidates for which we receive regulatory
approval, including building our own commercial organization to address certain markets. We will require additional capital for the further development
and commercialization of our product candidates, as well as to fund our other operating expenses and capital expenditures.

As a result of our recurring losses from operations, recurring negative cash flows from operations and substantial cumulative losses, there is

uncertainty regarding our ability to maintain liquidity sufficient to operate our business effectively, which raises substantial doubt about our ability to
continue as a going concern. If we are unsuccessful in our efforts to raise outside financing, we may be required to significantly reduce or cease operations.
The report of our independent registered public accounting firm on our audited financial statements for the year ended December 31, 2020 included a
“going concern” explanatory paragraph indicating that our recurring losses from operations, negative working capital, recurring negative cash flows from
operations and substantial cumulative net losses raise substantial doubt about our ability to continue as a going concern.

We cannot be certain that additional funding will be available on acceptable terms, or at all. If we are unable to raise additional capital in sufficient
amounts or on terms acceptable to us we may have to significantly delay, scale back or discontinue the development or commercialization of one or more
of our product candidates. We may also seek collaborators for one or more of our current or future product candidates at an earlier stage than otherwise
would be desirable or on terms that are less favorable than might otherwise be available. Any of these events could significantly harm our business,
financial condition and prospects.

25

 
Our future capital requirements will depend on many factors, including:

•

•

•

•

•

•

•

•

•

•

•

•

•

the progress of the development of our fully-human mAbs, including biosimilars/biobetters, fully human anti-PD-L1 and anti-PD-1
checkpoint inhibitors derived from our proprietary G-MAB™ library platform, ADCs, BsAbs, CAR-T and DAR-T for adoptive cellular
immunotherapy, RTX, SP-103 and SEMDEXATM and our COVID-19 product candidates;

the number of product candidates we pursue;

the time and costs involved in obtaining regulatory approvals;

the costs involved in filing and prosecuting patent applications and enforcing or defending patent claims;

our plans to establish sales, marketing and/or manufacturing capabilities;

the effect of competing technological and market developments;

the terms and timing of any collaborative, licensing and other arrangements that we may establish;

general market conditions for offerings from biopharmaceutical companies;

our ability to establish, enforce and maintain selected strategic alliances and activities required for product commercialization;

our obligations under our debt arrangements;

the time and costs involved in defending and enforcing our rights in various litigation matters;

the effect of the COVID-19 pandemic; and

our revenues, if any, from successful development and commercialization of our product candidates, including ZTlido.

In order to carry out our business plan and implement our strategy, we anticipate that we will need to obtain additional financing from time to time

and may choose to raise additional funds through strategic collaborations, licensing arrangements, joint ventures, public or private equity or debt financing,
bank lines of credit, asset sales, government grants or other arrangements. We cannot be sure that any additional funding, if needed, will be available on
terms favorable to us or at all. Furthermore, any additional equity or equity-related financing may be dilutive to our stockholders, and debt or equity
financing, if available, may subject us to restrictive covenants and significant interest costs. If we obtain funding through a strategic collaboration or
licensing arrangement, we may be required to relinquish our rights to certain of our product candidates or marketing territories.

In addition, as discussed in the risk factor under the heading “The terms of our outstanding debt place restrictions on our operating and financial

flexibility. If we raise additional capital through debt financing, the terms of any new debt could further restrict our ability to operate our business” below,
the Scilex Indenture includes negative covenants that place limitations on the following: the incurrence of debt, the payment of dividends by Scilex
Pharma, the repurchase of shares and, under certain conditions, making certain other restricted payments, the prepayment, redemption or repurchase of
subordinated debt, a merger, amalgamation or consolidation involving Scilex Pharma, engaging in certain transactions with affiliates; and the making of
investments other than those permitted by the Scilex Indenture.

Our inability to raise capital when needed would harm our business, financial condition and results of operations, and could cause our stock price to

decline or require that we wind down our operations altogether.

Risks Related to Our Business and Industry

We are heavily dependent on the success of our technologies and product candidates, and we cannot give any assurance that our product candidates
will receive regulatory approval, which is necessary before they can be commercialized.

To date, we have invested a significant portion of our efforts and financial resources in the acquisition and development of our product candidates.

As an early stage company, we have limited experience and have not yet demonstrated an ability to successfully overcome many of the risks and
uncertainties frequently encountered by companies in new and rapidly evolving fields, particularly in the biopharmaceutical area. Our future success is
substantially dependent on our ability to successfully develop, obtain regulatory approval for, and then successfully commercialize such product candidates.
Other than ZTlido, our product candidates are currently in preclinical development or in clinical trials. Our business depends entirely on the successful
development and commercialization of our product candidates, which may never occur. We currently do not generate significant revenues from sales of any
products, and we may not be able to develop or commercialize our product candidates.

26

 
 
 
 
 
 
 
 
 
 
 
 
 
 
The successful development, and any commercialization, of our technologies and any product candidates would require us to successfully perform a

variety of functions, including:

•

•

•

•

•

•

•

developing our technology platform;

seeking and obtaining intellectual property and/or proprietary rights to our technology and/or the technology of others;

identifying, developing, manufacturing and commercializing product candidates;

entering into successful licensing and other arrangements with product development partners;

participating in regulatory approval processes;

formulating and manufacturing products; and

conducting sales and marketing activities.

Our operations have been limited to organizing our company, acquiring, developing and securing our proprietary technology and identifying and

obtaining early preclinical data or clinical data for various product candidates. These operations provide a limited basis for you to assess our ability to
continue to develop our technology, identify product candidates, develop and commercialize any product candidates we can identify and enter into
successful collaborative arrangements with other companies, as well as for you to assess the advisability of investing in our securities. Each of these
requirements will require substantial time, effort and financial resources.

Each of our product candidates will require additional preclinical or clinical development, management of preclinical, clinical and manufacturing

activities, regulatory approval in multiple jurisdictions, obtaining manufacturing supply, building of a commercial organization, and significant marketing
efforts before we generate any revenues from product sales. We are not permitted to market or promote any of our product candidates before we receive
regulatory approval from the U.S. Food and Drug Administration (the “FDA”), the United Kingdom’s Medicines and Healthcare Products Regulatory
Agency (the “MHRA”), the European Medicines Agency (the “EMA”) or comparable foreign regulatory authorities, and we may never receive such
regulatory approval for any of our product candidates. In addition, our product development programs contemplate the development of companion
diagnostics by our third-party collaborators. Companion diagnostics are subject to regulation as medical devices and must themselves be approved for
marketing by the FDA, the MHRA, the EMA or certain other foreign regulatory agencies before we may commercialize our product candidates.

Delays in clinical testing could result in increased costs to us and delay our ability to generate revenue.

Although we are currently engaging in and planning for certain clinical trials relating to our COVID-19 product candidates, RTX, CAR-T and
biosimilar/biobetter antibodies and other product candidates, there can be no assurance that the FDA will accept our proposed trial designs. We may
experience delays in our clinical trials, and we do not know whether planned clinical trials will begin on time, need to be redesigned, enroll patients on time
or be completed on schedule, if at all. Clinical trials can be delayed for a variety of reasons, including delays related to:

•

•

•

•

•

•

•

•

•

obtaining regulatory approval to commence a trial;

reaching agreement on acceptable terms with prospective contract research organizations (“CROs”) and clinical trial sites, the terms of which
can be subject to extensive negotiation and may vary significantly among different CROs and trial sites;

obtaining institutional review board (“IRB”) approval at each site;

recruiting suitable patients to participate in a trial;

clinical sites deviating from trial protocol or dropping out of a trial;

having patients complete a trial or return for post-treatment follow-up;

developing and validating companion diagnostics on a timely basis, if required;

adding new clinical trial sites; or

manufacturing sufficient quantities of product candidate for use in clinical trials.

Patient enrollment, a significant factor in the timing of clinical trials, is affected by many factors, including the size and nature of the patient

population, the proximity of patients to clinical sites, the eligibility criteria for the trial, the design of the clinical trial,

27

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
competing clinical trials and clinicians’ and patients’ perceptions as to the potential advantages of the product candidate being studied in relation to other
available therapies, including any new drugs that may be approved for the indications we are investigating, as well as the COVID-19 pandemic.
Furthermore, we intend to rely on CROs and clinical trial sites to ensure the proper and timely conduct of our clinical trials and we intend to have
agreements governing their committed activities, but we will have limited influence over their actual performance.

We could encounter delays if a clinical trial is suspended or terminated by us, by the IRBs of the institutions in which such trials are being

conducted, by the Data Monitoring Committees (also known as Data and Safety Monitoring Board or Data and Safety Monitoring Committee) for such trial
or by the FDA or other regulatory authorities. Such authorities may impose such a suspension or termination due to a number of factors, including failure to
conduct the clinical trial in accordance with regulatory requirements or our clinical protocols, inspection of the clinical trial operations or trial site by the
FDA or other regulatory authorities resulting in the imposition of a clinical hold, unforeseen safety issues or adverse side effects, failure to demonstrate a
benefit from using a drug, changes in governmental regulations or administrative actions or lack of adequate funding to continue the clinical trial.

If we experience delays in the completion of, or termination of, any clinical trial of our product candidates, the commercial prospects of our product

candidates will be harmed, and our ability to generate product revenues from any of these product candidates will be delayed. In addition, any delays in
completing our clinical trials will increase our costs, slow down our product candidate development and approval process and jeopardize our ability to
commence product sales and generate revenues. Any of these occurrences may harm our business, financial condition and prospects significantly. In
addition, many of the factors that cause, or lead to, a delay in the commencement or completion of clinical trials may also ultimately lead to the denial of
regulatory approval of our product candidates.

Competition for patients in conducting clinical trials may prevent or delay product development and strain our limited financial resources.

Many pharmaceutical companies are conducting clinical trials in patients with the disease indications that our product candidates target. As a result,

we must compete with them for clinical sites, physicians and the limited number of patients who fulfill the stringent requirements for participation in
clinical trials. Also, due to the confidential nature of clinical trials, we do not know how many of the eligible patients may be enrolled in competing studies
and who are consequently not available to us for our clinical trials.

In addition, certain of our clinical trials have been affected by and may continue to be affected by the COVID-19 pandemic. Clinical site initiation

and patient enrollment for our non-COVID-19 product candidates have been and may continue to be delayed due to prioritization of hospital resources
toward the COVID-19 pandemic. Some patients have not been and others may not be able to comply with clinical trial protocols if quarantines impede
patient movement or interrupt healthcare services. Similarly, any inability to recruit and retain patients and principal investigators and site staff who, as
healthcare providers, may have heightened exposure to COVID-19, may adversely impact our clinical trial operations.

Our clinical trials may be delayed or terminated due to the inability to enroll enough patients. Patient enrollment depends on many factors, including
the size of the patient population, the nature of the trial protocol, the proximity of patients to clinical sites, the eligibility criteria for the study and potential
reduced enrollment due to the COVID-19 pandemic. The delay or inability to meet planned patient enrollment may result in increased costs and delays or
termination of the trial, which could have a harmful effect on our ability to develop products.

The regulatory approval processes of the FDA, the MHRA, the EMA and comparable foreign authorities are lengthy, time consuming and inherently
unpredictable, and if we are ultimately unable to obtain regulatory approval for our product candidates, our business will be substantially harmed.

The time required to obtain approval from the FDA, the MHRA, the EMA and comparable foreign authorities is unpredictable but typically takes

many years following the commencement of clinical trials and depends upon numerous factors, including the substantial discretion of the regulatory
authorities. In addition, approval policies regulations, or the type and amount of clinical data necessary to gain approval may change during the course of a
product candidate’s clinical development and may vary among jurisdictions. Other than ZTlido, we have not obtained regulatory approval for any product
candidate and it is possible that none of our existing product candidates or any product candidates we may seek to develop in the future will ever obtain
regulatory approval.

28

 
We may fail to receive regulatory approval for our product candidates for many reasons, including the following:

•

•

•

•

•

•

•

•

•

the FDA, the MHRA, the EMA or comparable foreign regulatory authorities may disagree with the design or implementation of our clinical
trials;

we may be unable to demonstrate to the satisfaction of the FDA, the MHRA, the EMA or comparable foreign regulatory authorities that a
product candidate is safe and effective for its proposed indication;

the results of clinical trials may not meet the level of statistical significance required for approval by the FDA, the MHRA, the EMA or
comparable foreign regulatory authorities;

the FDA, the MHRA, the EMA or comparable foreign regulatory authorities may disagree with our interpretation of data from preclinical
studies or clinical trials;

the data collected from clinical trials of our product candidates may not be sufficient to support the submission of a new drug application
(“NDA”), a marketing authorization application (“MAA”) or other submission or to obtain regulatory approval in the U.S., the United
Kingdom, the European Union or elsewhere;

the data obtained from studies in one jurisdiction, such as the United States, may not be accepted by regulatory authorities in other
jurisdictions, and certain jurisdictions may require data from studies conducted in their country in order to obtain regulatory approval;

the FDA, the MHRA, the EMA or comparable foreign regulatory authorities may fail to approve the manufacturing processes or facilities of
third-party manufacturers with which we contract for clinical and commercial supplies;

the FDA, the MHRA, the EMA or comparable foreign regulatory authorities may fail to approve the companion diagnostics we contemplate
developing with partners; and

the approval policies or regulations of the FDA, the MHRA, the EMA or comparable foreign regulatory authorities may significantly change
in a manner rendering our clinical data insufficient for approval.

This lengthy approval process as well as the unpredictability of future clinical trial results may result in our failing to obtain regulatory approval to

market our product candidates, which would significantly harm our business, results of operations and prospects.

In addition, even if we were to obtain approval, regulatory authorities may approve any of our product candidates for fewer or more limited
indications than we request, may not approve the price we intend to charge for our products, may grant approval contingent on the performance of costly
post-marketing clinical trials, or may approve a product candidate with a label that does not include the labeling claims necessary or desirable for the
successful commercialization of that product candidate. Any of the foregoing scenarios could materially harm the commercial prospects for our product
candidates.

Other than an NDA submitted by Scilex Pharmaceuticals Inc. (“Scilex Pharma”) for Scilex Pharma’s lead product candidate, ZTlido, which was
approved by the FDA in February 2018, and an MAA filed in Europe (which was subsequently withdrawn in 2019), we have not previously submitted a
BLA or an NDA to the FDA, an MAA to the MHRA or the EMA or similar drug approval filings to comparable foreign authorities, for any product
candidate, and we cannot be certain that any of our product candidates will be successful in clinical trials or receive regulatory approval. Further, our
product candidates may not receive regulatory approval even if our clinical trials are successful. If we do not receive regulatory approvals for our product
candidates, we may not be able to continue our operations. Even if we successfully obtain regulatory approvals to market one or more of our product
candidates, our revenues will be dependent, in some instances, upon our collaborators’ ability to obtain regulatory approval of the companion diagnostics to
be used with our product candidates, as well as the size of the markets in the territories for which we gain regulatory approval and have commercial rights.
If the markets for patients that we are targeting for our product candidates are not as significant as we estimate, we may not generate significant revenues
from sales of such products, if approved.

We plan to seek regulatory approval to commercialize our product candidates in the U.S., the United Kingdom, the European Union and in

additional foreign countries. While the scope of regulatory approval is similar in other countries, to obtain separate regulatory approval in many other
countries we must comply with numerous and varying regulatory requirements of such countries regarding safety and efficacy and governing, among other
things, clinical trials and commercial sales, pricing and distribution of our product candidates, and we cannot predict success in these jurisdictions. In
addition, our failure to obtain regulatory approval in any country may delay or have negative effects on the process for regulatory approval in other
countries. If we fail to comply with regulatory requirements in international markets or to obtain and maintain required approvals, our target market will be
reduced and our ability to realize the full market potential of our products or product candidates will be harmed. Further, the United Kingdom has
withdrawn from the European Union. We cannot predict what consequences the withdrawal of the United Kingdom from the European Union might have
on the regulatory frameworks of the United Kingdom or the European Union, or on our future operations, if any, in these jurisdictions.

29

 
 
 
 
 
 
 
 
 
 
Inadequate funding for the FDA, the MHRA, the EMA and comparable foreign authorities and government agencies could hinder their ability to hire
and retain key leadership and other personnel, prevent new products and services from being developed or commercialized in a timely manner or
otherwise prevent those agencies from performing normal business functions on which the operation of our business may rely, which could negatively
impact our business.

The ability of the FDA, the MHRA, the EMA and comparable foreign authorities to review and approve new products can be affected by a variety

of factors, including government budget and funding levels, ability to hire and retain key personnel and accept the payment of user fees, and statutory,
regulatory and policy changes and the impact of crises that hinder its operations, such as COVID-19. Average review times at the agency have fluctuated in
recent years as a result. In addition, government funding of other government agencies on which our operations may rely, including those that fund research
and development activities, is subject to the political process, which is inherently fluid and unpredictable.

Disruptions at the FDA, the MHRA, the EMA and comparable foreign authorities may also slow 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 FDA and other government
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.

Our approach to the discovery and development of product candidates that target ADCs or iTAbs is unproven, and we do not know whether we will be
able to develop any products of commercial value.

ADCs and intracellular targeting antibodies (“iTAbs”) are emerging technologies and, consequently, it is conceivable that such technologies may
ultimately fail to identify commercially viable products to treat human patients with cancer or other diseases. Due to the unproven nature of ADCs and
iTAbs, significant further research and development activities will be required. We may incur substantial costs in connection with such research and
development activities and there is no guarantee that these activities will lead to the identification of commercially viable products.

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

We are currently advancing multiple product candidates for a variety of indications. Simultaneously advancing so many product candidates creates a

significant strain on our limited human and financial resources. As a result, we may not be able to provide sufficient resources to any single product
candidate to permit the successful development and commercialization of such product candidate, causing material harm to our business. 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 products.

If, due to our limited resources and access to capital, we prioritize development of certain product candidates that ultimately prove to be

unsuccessful, we may forego or delay pursuit of opportunities with other product candidates or for other indications that later prove to have greater
commercial potential or a greater likelihood of success. Our resource allocation decisions may cause us to fail to capitalize on viable commercial products
or profitable market opportunities. 

Our product candidates may cause undesirable side effects or have other properties that could delay or prevent their regulatory approval, limit the
commercial profile of an approved label, or result in significant negative consequences following marketing approval, if any.

Undesirable side effects caused by our product candidates could cause us or regulatory authorities to interrupt, delay or halt clinical trials and could

result in a more restrictive label or the delay or denial of regulatory approval by the FDA or other comparable foreign authorities. Results of our trials could
reveal a high and unacceptable severity and prevalence of these or other side effects. In such an event, our trials could be suspended or terminated, and the
FDA or comparable foreign regulatory authorities could order us to cease further development of or deny approval of our product candidates for any or all
targeted indications. The drug-related side effects could affect patient recruitment or the ability of enrolled patients to complete the trial or result in
potential product liability claims. Any of these occurrences may harm our business, financial condition and prospects significantly.

30

 
Additionally, if we receive marketing approval for one or more of our product candidates, and we or others later identify undesirable side effects

caused by such products, a number of potentially significant negative consequences could result, including:

•

•

•

•

•

regulatory authorities may withdraw approvals of such products;

regulatory authorities may require additional warnings on the label;

we may be required to create a medication guide outlining the risks of such side effects for distribution to patients;

we could be sued and held liable for harm caused to patients; and

our reputation may suffer.

Any of these events could prevent us from achieving or maintaining market acceptance of the particular product candidate or for particular

indications of a product candidate, if approved, and could significantly harm our business, results of operations and prospects.

We rely on third parties to conduct our preclinical and clinical trials. If these third parties do not successfully perform their contractual legal and
regulatory duties or meet expected deadlines, we may not be able to obtain regulatory approval for or commercialize our product candidates and our
business could be substantially harmed.

We have relied upon and plan to continue to rely upon third-party CROs to monitor and manage data for our ongoing preclinical and clinical
programs. We rely on these parties for execution of our preclinical and clinical trials, and control only certain aspects of their activities. Nevertheless, we
are responsible for ensuring that each of our studies is conducted in accordance with the applicable protocol, legal, regulatory and scientific standards, and
our reliance on the CROs does not relieve us of our regulatory responsibilities. We and our CROs are required to comply with current good clinical
practices (“cGCP”), which are regulations and guidelines enforced by the FDA, the Competent Authorities of the Member States of the European
Economic Area, and comparable foreign regulatory authorities for all of our product candidates in clinical development.

Regulatory authorities enforce these cGCPs through periodic inspections of trial sponsors, principal investigators and trial sites. If we or any of our
CROs fail to comply with applicable cGCPs, the clinical data generated in our clinical trials may be deemed unreliable and the FDA, the MHRA, the EMA
or comparable foreign regulatory authorities may require us to perform additional clinical trials before approving our marketing applications or may not
approve our marketing applications. We cannot assure you that upon inspection by a given regulatory authority, such regulatory authority will determine
that any of our clinical trials comply with cGCP regulations. In addition, our clinical trials must be conducted with product produced under current good
manufacturing practices (“cGMP”) regulations. Our failure to comply with these regulations may require us to repeat clinical trials, which would delay the
regulatory approval process.

If any of our relationships with these third-party CROs terminate, we may not be able to enter into arrangements with alternative CROs or to do so
on commercially reasonable terms. In addition, our CROs are not our employees, and except for remedies available to us under our agreements with such
CROs, we cannot control whether or not they devote sufficient time and resources to our on-going clinical, nonclinical and preclinical programs. If CROs
do not successfully carry out their contractual duties or obligations or meet expected deadlines, if they need to be replaced or if the quality or accuracy of
the clinical data they obtain is compromised due to the failure to adhere to our clinical protocols, regulatory requirements or for other reasons, our clinical
trials may be extended, delayed or terminated and we may not be able to obtain regulatory approval for or successfully commercialize our product
candidates. As a result, our results of operations and the commercial prospects for our product candidates would be harmed, our costs could increase and
our ability to generate revenues could be delayed.

Switching or adding additional CROs involves additional cost and requires management time and focus. In addition, there is a natural transition
period when a new CRO commences work. As a result, delays occur, which can materially impact our ability to meet our desired clinical development
timelines. Though we carefully manage our relationships with our CROs, there can be no assurance that we will not encounter similar challenges or delays
in the future or that these delays or challenges will not have a material adverse impact on our business, financial condition and prospects.

If we fail to comply with manufacturing regulations, our financial results and financial condition will be adversely affected.

We currently manufacture some of our preclinical and clinical materials in-house. In addition, we may enter into collaboration and license
agreements with certain collaborators, pursuant to which we may, among other things, agree to carry out manufacturing of our collaborators’ material and
product candidates. However, we only recently began manufacturing such materials and do not have significant prior experience manufacturing preclinical
or clinical materials or product candidates. Before we can begin commercial manufacture of our or any potential collaborators’ materials or product
candidates, regulatory authorities must approve marketing

31

 
 
 
 
 
 
applications that identify manufacturing facilities operated by us or our contract manufacturers that have passed regulatory inspection and manufacturing
processes that are acceptable to the regulatory authorities. In addition, our pharmaceutical manufacturing facilities are continuously subject to scheduled
and unannounced inspection by the FDA and international regulatory authorities, before and after product approval, to monitor and ensure compliance with
cGMP and other regulations. Additionally, we may use contract manufacturers for the manufacture of our product candidates from time to time based on
capacity needs. Although we are not involved in the day-to-day operations of our contract manufacturers, we are ultimately responsible for ensuring that
our products are manufactured in accordance with cGMP regulations.

Due to the complexity of the processes used to manufacture our product candidates and our potential collaborators’ product candidates, we may be

unable to continue to pass or initially pass federal or international regulatory inspections in a cost-effective manner. For the same reason, any potential
third-party manufacturer of our product candidates may be unable to comply with cGMP regulations in a cost-effective manner and may be unable to
initially or continue to pass a federal or international regulatory inspection.

If we, or third-party manufacturers with whom we contract, are unable to comply with manufacturing regulations, we may be subject to delay of

approval of our product candidates, warning or untitled letters, fines, unanticipated compliance expenses, recall or seizure of our products, total or partial
suspension of production and/or enforcement actions, including injunctions, and criminal or civil prosecution. These possible sanctions would adversely
affect our financial results and financial condition.

With specific regard to ZTlido and other drug products we do not manufacture in-house, but rather through a third-party manufacturer, if a third-

party manufacturer upon which we rely fails to produce drug candidates that we require on a timely basis, or to comply with stringent regulations
applicable to pharmaceutical drug manufacturers, we may face delays in the trials, regulatory submissions, required approvals or commercialization of our
drug candidates. The manufacture of pharmaceutical products requires significant expertise and capital investment, including the development of advanced
manufacturing techniques and process controls. Manufacturers of pharmaceutical products often encounter difficulties in production, which include
difficulties with production costs and yields, quality control and assurance and shortages of qualified personnel, as well as compliance with strictly
enforced federal, state and foreign regulations. The third-party manufacturers we contract with may not perform as agreed or may terminate their
agreements with us. Any of these factors could cause us to delay or suspend any future clinical trials, regulatory submissions, required approvals or
commercialization of one or more of our drug candidates, entail higher costs and result in our being unable to effectively commercialize products.

Material necessary to manufacture product candidates may not be available on commercially reasonable terms, or at all, which may delay the
development and commercialization of product candidates.  

There are a limited number of suppliers for raw materials that we use to manufacture our products and product candidates and there may be a need

to assess alternate suppliers to prevent a possible disruption of the manufacture of the materials necessary to produce our product candidates for clinical
trials, and if approved, ultimately for commercial sale. We do not have any control over the process or timing of the acquisition of these raw materials by
us. We typically do not have any agreements for the commercial production of these raw materials. Any significant delay in the supply of a product
candidate, or the raw material components thereof, for an ongoing clinical trial due to the need to obtain or replace a third-party manufacturer could
considerably delay completion of our clinical trials, product testing and potential regulatory approval of our product candidates. If we are unable to
purchase these raw materials after regulatory approval has been obtained for our product candidates, the commercial launch of our product candidates
would be delayed or there would be a shortage in supply, which would impair our ability to generate revenues from the sale of our product candidates.

We may not be able to manufacture our products or product candidates in commercial quantities, which would prevent us from commercializing our
products and product candidates.

We are largely dependent on our third-party manufacturers to conduct process development and scale-up work necessary to support greater clinical

development and commercialization requirements for our products and product candidates. Carrying out these activities in a timely manner, and on
commercially reasonable terms, is critical to the successful development and commercialization of our products and product candidates. We expect our
third-party manufacturers are capable of providing sufficient quantities of our products and product candidates to meet anticipated clinical and full-scale
commercial demands; however, if third parties with whom we currently work are unable to meet our supply requirements, we will need to secure alternate
suppliers or face potential delays or shortages. While we believe that there are other contract manufacturers with the technical capabilities to manufacture
our products and product candidates, we cannot be certain that identifying and establishing relationships with such sources would not result in significant
delay or material additional costs.

32

 
The complexities and regulations related to our manufacturing and development services businesses subject us to potential risks.

Through certain subsidiaries, we offer development (e.g., conjugation) and manufacturing services that are highly complex, due in part to strict

regulatory requirements. A failure of our quality control systems in our facilities could cause problems to arise in connection with facility operations for a
variety of reasons, including equipment malfunction, contamination, failure to follow specific manufacturing instructions, protocols and standard operating
procedures, problems with raw materials or environmental factors. Such problems could affect production of a single manufacturing run or a series of runs,
requiring the destruction of products, or could halt manufacturing operations altogether. In addition, our failure to meet required quality standards may
result in our failure to timely deliver products to our customers or collaborators, which in turn could damage our reputation for quality and service. Any
such incident could, among other things, lead to increased costs, lost revenue, reimbursement to customers for lost drug substance, damage to and possibly
termination of existing customer relationships, time and expense spent investigating the cause and, depending on the cause, similar losses with respect to
other manufacturing runs. With respect to our commercial manufacturing, if problems are not discovered before the product is released to the market, we
may be subject to regulatory actions, including product recalls, product seizures, injunctions to halt manufacture and distribution, restrictions on our
operations, civil sanctions, including monetary sanctions, and criminal actions. In addition, such issues could subject us to litigation and/or liability for
damages, the cost of which could be significant.

Regulatory agencies may periodically inspect our manufacturing facilities to ensure compliance with applicable legal, regulatory and local

requirements, such as cGMP requirements. Failure to comply with these requirements may subject us to possible legal or regulatory actions, such as
suspension of manufacturing, seizure of product or voluntary recall of a product.

We face potential business disruptions and related risks resulting from the recent outbreak of the novel coronavirus, which could have a material
adverse effect on our business, financial condition and results of operations.

In December 2019, a novel strain of coronavirus, or SARS-CoV-2, was reported to have surfaced in Wuhan, China. SARS-CoV-2 is the virus that

causes COVID-19. The COVID-19 outbreak has grown into a global pandemic that has impacted Asia, the United States, Europe and other countries
throughout the world. Financial markets have been experiencing extreme fluctuations that may cause a contraction in available liquidity globally as
important segments of the credit markets react to the development. The pandemic may lead to a decline in business and consumer confidence. The global
outbreak of COVID-19 continues to rapidly evolve. As a result, businesses have closed and limits have been placed on travel. The extent to which COVID-
19 may impact our business, clinical trials and sales of ZTlido will depend on future developments, which are highly uncertain and cannot be predicted
with confidence, such as the ultimate geographic spread of the disease, the duration of the outbreak, travel restrictions and social distancing in the United
States and other countries, business closures or business disruptions and the effectiveness of actions taken in the United States and other countries to
contain and treat the disease.

We are monitoring the potential impact of the COVID-19 outbreak, and if COVID-19 continues to spread globally, including in the United States,

we may experience disruptions that could severely impact the development of our product candidates, including:

•

•

•

•

•

•

•

•

•

delays or difficulties in enrolling patients in our clinical trials as patients may be reluctant, or unable, to visit clinical sites;

delays or difficulties in clinical site initiation, including difficulties in recruiting clinical site investigators, clinical site staff and potential
closure of clinical facilities;

decreases in patients seeking treatment for chronic pain;

delays in receiving approval from local regulatory authorities to initiate our planned clinical trials;

delays in clinical sites receiving the supplies and materials needed to conduct our clinical trials, including interruption in global shipping that
may affect the transport of clinical trial materials;

changes in local regulations as part of a response to the COVID-19 outbreak, which may require us to change the ways in which our clinical
trials are conducted, which may result in unexpected costs, or to discontinue the clinical trials altogether;

diversion of healthcare resources away from the conduct of clinical trials, including the diversion of hospitals serving as our clinical trial sites
and hospital staff supporting the conduct of our clinical trials;

risk that participants enrolled in our clinical trials will acquire COVID-19 while the clinical trial is ongoing, which could impact the results of
the clinical trial, including by increasing the number of observed adverse events;

delays in necessary interactions with local regulators, ethics committees and other important agencies and contractors due to limitations in
employee resources or forced furlough of government employees; and

33

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
•

interruption of key clinical trial activities, such as clinical trial site monitoring, due to limitations on travel imposed or recommended by
federal or state governments, employers and others.

Quarantines, shelter-in-place and similar government orders, or the perception that such orders, shutdowns or other restrictions on the conduct of

business operations could occur, related to COVID-19 or other infectious diseases could impact personnel at third-party suppliers in the United States and
other countries, or the availability or cost of materials, which would disrupt our supply chain. Any manufacturing supply interruption of materials could
adversely affect our ability to conduct ongoing and future research and testing activities. For example, we obtain our commercial supply of ZTlido and our
clinical supply of SP-103 exclusively from Oishi and Itochu in Japan. The COVID-19 pandemic may result in delays in the procurement and shipping of
ZTlido, which may have an adverse impact on our operating results.

The spread of COVID-19, which has caused a broad impact globally, may materially affect us economically. While the potential economic impact

brought by, and the duration of, COVID-19 may be difficult to assess or predict, a widespread pandemic could result in significant disruption of global
financial markets, reducing our ability to access capital, which could in the future negatively affect our liquidity. In addition, a recession or market
correction resulting from the spread of COVID-19 could materially affect our business and the value of our common stock.

In addition, the continued spread of COVID-19 globally could materially and adversely impact our operations, including without limitation, our

sales and marketing efforts, sales of ZTlido, travel, employee health and availability, which may have a material and adverse effect on our business,
financial condition and results of operations.

Management is actively monitoring the global situation on our financial condition, liquidity, operations, suppliers, industry and workforce. Given

the daily evolution of the COVID-19 outbreak and the global responses to curb its spread, we are not able to estimate the effects of the COVID-19 outbreak
on our results of operations, financial condition or liquidity for fiscal year 2021.

Failure to comply with existing and future regulatory requirements as a contract manufacturing organization could adversely affect our business,
results of operations and financial condition.

Operations as a contract manufacturing organization (“CMO”) are highly regulated. As a CMO, we are required to comply with the regulatory

requirements of various local, state, provincial, national and international regulatory bodies having jurisdiction in the countries or localities in which we
may manufacture products or product candidates or in which our collaborators’ products or product candidates are distributed. In particular, we are subject
to laws and regulations concerning development, testing, manufacturing processes, equipment and facilities, including compliance with cGMPs, import and
export regulations, and product registration and listing, among other things. As a result, our facilities are subject to regulation by the FDA, as well as
regulatory bodies of other jurisdictions such as the EMA, depending on the countries in which our collaborators develop the products or product candidates
we manufacture on their behalf. As we expand our operations and geographic scope, we may be exposed to more complex and new regulatory and
administrative requirements and legal risks, any of which may require expertise in which we have little or no experience. It is possible that compliance with
new regulatory requirements could impose significant compliance costs on us. Such costs could have a material adverse effect on our business, financial
condition and results of operations.

These regulatory requirements impact many aspects of our operations, including manufacturing, developing, storage, distribution, import and export

and record keeping related to collaborators’ products or product candidates. Noncompliance with any applicable regulatory requirements can result in
government refusal to approve (i) facilities for testing or manufacturing product candidates or (ii) potential products for commercialization. The FDA and
other regulatory agencies can delay, limit or deny approval for many reasons, including:

•

•

•

•

changes to the regulatory approval process, including new data requirements for products or product candidates in those jurisdictions,
including the United States, in which our customers may be seeking approval;

that a collaborator’s product or product candidate may not be deemed to be safe or effective;

the ability of the regulatory agency to provide timely responses as a result of its resource constraints; and

that the manufacturing processes or facilities may not meet the applicable requirements.

In addition, if new legislation or regulations are enacted or existing legislation or regulations are amended or are interpreted or enforced differently,
we may be required to obtain additional approvals or operate according to different manufacturing or operating standards. This may require a change in our
development and manufacturing techniques or additional capital investments in our facilities. Any related costs may be significant. If we fail to comply
with applicable regulatory requirements in the future, then we may be subject to warning letters and/or civil or criminal penalties and fines, suspension or
withdrawal of regulatory approvals, product recalls, seizure of products, restrictions on the import and export of products, debarment, exclusion,
disgorgement of profits, operating

34

 
 
 
 
 
 
 
restrictions and criminal prosecution and the loss of contracts and resulting revenue losses. Inspections by regulatory authorities that identify any
deficiencies could result in remedial actions, production stoppages or facility closure, which would disrupt the manufacturing process and supply of
product to our collaborators. In addition, such failure to comply could expose us to contractual and product liability claims, including claims by
collaborators for reimbursement for lost or damaged active pharmaceutical ingredients or recall or other corrective actions, the costs of which could be
significant.

In addition, certain product candidates we manufacture must undergo pre-clinical and clinical evaluations relating to product safety and efficacy

before they are approved as commercial therapeutic products. The regulatory authorities having jurisdiction in the countries in which we or our
collaborators intend to market their products may delay or put on hold clinical trials or delay approval of a product or determine that the product is not
approvable. The FDA or other regulatory agencies can delay approval of a product candidate if our manufacturing facility, including any newly
commissioned facility, is not able to demonstrate compliance with cGMPs, pass other aspects of pre-approval inspections or properly scale up to produce
commercial supplies. The FDA and comparable government authorities having jurisdiction in the countries in which we or our collaborators may market
approved products have the authority to withdraw product approval or suspend manufacture if there are significant problems with raw materials or supplies,
quality control and assurance or the product we manufacture is adulterated or misbranded. If our manufacturing facilities and services are not in compliance
with FDA and comparable government authorities, we may be unable to obtain or maintain the necessary approvals to continue manufacturing product
candidates for our customers, which would materially adversely affect our results of operations and financial condition.

The consumers of any approved products we manufacture for our collaborators may significantly influence our business, results of operations and
financial condition.

We will depend on, and have no control over, consumer demand for any approved products we manufacture for our collaborators. Consumer
demand for our collaborators’ products could be adversely affected by, among other things, delays in health regulatory approval, the inability of our
collaborators to demonstrate the efficacy and safety of their products, the loss of patent and other intellectual property rights protection, the emergence of
competing or alternative products, including generic drugs, the degree to which private and government payment subsidies for a particular product offset
the cost to consumers and changes in the marketing strategies for such products. If the products we manufacture for our collaborators do not gain market
acceptance, our revenues and profitability may be adversely affected.

Continued changes to the healthcare industry, including ongoing healthcare reform, adverse changes in government or private funding of healthcare

products and services, legislation or regulations governing the privacy of patient information or patient access to care, or the delivery, pricing or
reimbursement of pharmaceuticals and healthcare services or mandated benefits, may cause healthcare industry participants to purchase fewer services
from us or influence the price that others are willing to pay for our services. Changes in the healthcare industry’s pricing, selling, inventory, distribution or
supply policies or practices could also significantly reduce our revenue and profitability.

If production volumes of key products that we manufacture for our collaborators decline, results of operations and financial condition may continue

to be adversely affected.

If we do not successfully commercialize our products, our business, financial condition and results of operations will be materially and adversely
affected.

With the exception of Scilex Holding (which commercially launched, through Scilex Pharma, ZTlido in late October 2018, using a contract sales

organization to conduct its primary sales activities), we currently have no sales and marketing organization. If any of our product candidates are approved
by the FDA, we intend to market that product through our own sales force. We will incur significant additional expenses and commit significant additional
management resources to establish our sales force. We may not be able to establish these capabilities despite these additional expenditures. We will also
have to compete with other pharmaceutical and biotechnology companies to recruit, hire and train sales and marketing personnel. If we elect to rely on third
parties to sell our product candidates in the U.S., we may receive less revenue than if we sold our products directly. In addition, although we would intend
to use due diligence in monitoring their activities, we may have little or no control over the sales efforts of those third parties. In the event we are unable to
develop our own sales force or collaborate with a third party to sell our product candidates, we may not be able to commercialize our product candidates
which would negatively impact our ability to generate revenue.

Scilex Holding’s commercialization efforts of ZTlido have been primarily focused in the United States. Commercialization of ZTlido and other

future product candidates outside of the United States, to the extent pursued, is likely to require collaboration with one or more third parties.

35

 
In addition to the risks discussed elsewhere in this section, Scilex Holding’s ability to successfully commercialize and generate revenues from

ZTlido depends on a number of factors, including, but not limited to, Scilex Holding’s ability to:

•

•

•

•

•

•

•

develop and execute our sales and marketing strategies for Scilex Holding’s products;

achieve, maintain and grow market acceptance of, and demand for, Scilex Holding’s products;

obtain and maintain adequate coverage, reimbursement and pricing from managed care, government and other third-party payers;

maintain, manage or scale the necessary sales, marketing, manufacturing, managed markets, and other capabilities and infrastructure that are
required to successfully integrate and commercialize our products;

obtain adequate supply of Scilex Holding’s products;

maintain and extend intellectual property protection for Scilex Holding’s products; and

comply with applicable legal and regulatory requirements.

If Scilex Holding is unable to successfully achieve or perform these functions, Scilex Holding will not be able to maintain or increase its product

revenues and our business, financial condition and results of operations will be materially and adversely affected.

We may need others to market and commercialize our product candidates in international markets.

In the future, if appropriate regulatory approvals are obtained, we may commercialize our product candidates in international markets. However, we

have not decided how to commercialize our product candidates in those markets. We may decide to build our own sales force or sell our products through
third parties. If we decide to sell our product candidates in international markets through a third party, we may not be able to enter into any marketing
arrangements on favorable terms or at all. In addition, these arrangements could result in lower levels of income to us than if we marketed our product
candidates entirely on our own. If we are unable to enter into a marketing arrangement for our product candidates in international markets, we may not be
able to develop an effective international sales force to successfully commercialize those products in international markets. If we fail to enter into
marketing arrangements for our products and are unable to develop an effective international sales force, our ability to generate revenue would be limited.

With respect to ZTlido and any of our product candidates for which we may receive regulatory approvals, we will be subject to ongoing obligations and
continued regulatory review, which may result in significant additional expense. Additionally, our product candidates, if approved, could be subject to
labeling and other restrictions and market withdrawal and we may be subject to penalties if we fail to comply with regulatory requirements or
experience unanticipated problems with our products.

Our FDA approval for ZTlido and any other regulatory approvals that we may receive for our product candidates may be subject to limitations on
the approved indicated uses for which the product may be marketed or to the conditions of approval, or contain requirements for potentially costly post-
marketing testing, including Phase IV clinical trials, and surveillance to monitor the safety and efficacy of the product candidate. In addition, if the FDA or
a comparable foreign regulatory authority approves any of our product candidates, the manufacturing processes, labeling, packaging, distribution, adverse
event reporting, storage, advertising, promotion and recordkeeping for the product will be subject to extensive and ongoing regulatory requirements. These
requirements include submissions of safety and other post-marketing information and reports, registration, as well as continued compliance with cGMPs
and cGCPs for any clinical trials that we conduct post-approval. The future discovery of previously unknown problems with a product, including adverse
events of unanticipated severity or frequency, or with our third-party manufacturers or manufacturing processes, or failure to comply with regulatory
requirements, may result in, among other things:

•

•

•

•

•

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

fines, warning letters or holds on clinical trials;

refusal by the FDA to approve pending applications or supplements to approved applications filed by us, or suspension or revocation of
product license approvals;

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

injunctions or the imposition of civil or criminal penalties.

The FDA’s policies may change, and additional government regulations may be enacted that could prevent, limit or delay regulatory approval of our

product candidates. If we are slow or unable to adapt to changes in existing requirements or the adoption of

36

 
 
 
 
 
 
 
 
 
 
 
 
 
new requirements or policies, or if we are not able to maintain regulatory compliance, we may lose any marketing approval that we may have obtained,
which would adversely affect our business, prospects and ability to achieve or sustain profitability.

We will need to obtain FDA approval of any proposed product brand names, and any failure or delay associated with such approval may adversely
impact our business.

A pharmaceutical product cannot be marketed in the U.S. or other countries until we have completed rigorous and extensive regulatory review

processes, including approval of a brand name. Any brand names we intend to use for our product candidates will require approval from the FDA
regardless of whether we have secured a formal trademark registration from the U.S. Patent and Trademark Office (the “PTO”). The FDA typically
conducts a review of proposed product brand names, including an evaluation of potential for confusion with other product names. The FDA may also
object to a product brand name if it believes the name inappropriately implies medical claims. If the FDA objects to any of our proposed product brand
names, we may be required to adopt an alternative brand name for our product candidates. If we adopt an alternative brand name, we would lose the benefit
of our existing trademark applications for such product candidate and may be required to expend significant additional resources in an effort to identify a
suitable product brand name that would qualify under applicable trademark laws, not infringe the existing rights of third parties and be acceptable to the
FDA. We may be unable to build a successful brand identity for a new trademark in a timely manner or at all, which would limit our ability to
commercialize our product candidates.

Our failure to successfully discover, acquire, develop and market additional product candidates or approved products would impair our ability to grow.

As part of our growth strategy, we intend to develop and market additional products and product candidates. We are pursuing various therapeutic
opportunities through our product pipeline. We may spend several years completing our development of any particular current or future internal product
candidate, and failure can occur at any stage. The product candidates to which we allocate our resources may not end up being successful. In addition,
because our internal research capabilities are limited, we may be dependent upon pharmaceutical and biotechnology companies, academic scientists and
other researchers to sell or license products or technology to us. The success of this strategy depends partly upon our ability to identify, select, discover and
acquire promising pharmaceutical product candidates and products. Failure of this strategy would impair our ability to grow.

The process of proposing, negotiating and implementing a license or acquisition of a product candidate or approved product is lengthy and complex.
Other companies, including some with substantially greater financial, marketing and sales resources, may compete with us for the license or acquisition of
product candidates and approved products. We have limited resources to identify and execute the acquisition or in-licensing of third-party products,
businesses and technologies and integrate them into our current infrastructure. Moreover, we may devote resources to potential acquisitions or in-licensing
opportunities that are never completed, or we may fail to realize the anticipated benefits of such efforts. We may not be able to acquire the rights to
additional product candidates on terms that we find acceptable, or at all.

In addition, future acquisitions may entail numerous operational and financial risks, including:

•

•

•

•

•

•

•

•

•

disruption of our business and diversion of our management’s time and attention to develop acquired products or technologies;

incurrence of substantial debt, dilutive issuances of securities or depletion of cash to pay for acquisitions;

higher than expected acquisition and integration costs;

difficulty in combining the operations and personnel of any acquired businesses with our operations and personnel;

increased amortization expenses;

impairment of relationships with key suppliers or customers of any acquired businesses due to changes in management and ownership;

impairment of our ability to obtain intellectual property rights or rights to commercialize additional product candidates, or increased cost to
obtain such rights;

inability to motivate key employees of any acquired businesses; and

assumption of known and unknown liabilities.

Further, any product candidate that we acquire may require additional development efforts prior to commercial sale, including extensive clinical

testing and approval by the FDA and applicable foreign regulatory authorities. All product candidates are prone to

37

 
 
 
 
 
 
 
 
 
 
risks of failure typical of pharmaceutical product development, including the possibility that a product candidate will not be shown to be sufficiently safe
and effective for approval by regulatory authorities.

Our commercial success depends upon us attaining significant market acceptance of our product candidates, if approved for sale, among physicians,
patients, healthcare payors and major operators of cancer and other clinics.

Even if we obtain regulatory approval for our product candidates, the product may not gain market acceptance among physicians, health care payors,

patients and the medical community, which are critical to commercial success. Market acceptance of any product candidate for which we receive approval
depends on a number of factors, including:

•

•

•

•

•

•

•

•

•

•

•

the efficacy and safety as demonstrated in clinical trials;

the timing of market introduction of such product candidate as well as competitive products;

the clinical indications for which the product candidate is approved;

acceptance by physicians, major operators of cancer clinics and patients of the product candidate as a safe and effective treatment;

the safety of such product candidate seen in a broader patient group, including its use outside the approved indications;

the availability, cost and potential advantages of alternative treatments, including less expensive generic drugs;

the availability of adequate reimbursement and pricing by third-party payors and government authorities;

the product labeling or product insert required by the FDA or regulatory authority in other countries;

the approval, availability, market acceptance and reimbursement for a companion diagnostic, if any;

the prevalence and severity of adverse side effects; and

the effectiveness of our sales and marketing efforts.

If any product candidate that we develop does not provide a treatment regimen that is as beneficial as, or is perceived as being as beneficial as, the

current standard of care or otherwise does not provide patient benefit, that product candidate, if approved for commercial sale by the FDA or other
regulatory authorities, likely will not achieve market acceptance. Our ability to effectively promote and sell any approved products will also depend on
pricing and cost-effectiveness, including our ability to produce a product at a competitive price and our ability to obtain sufficient third-party coverage or
reimbursement. If any product candidate is approved but does not achieve an adequate level of acceptance by physicians, patients and third-party payors,
our ability to generate revenues from that product would be substantially reduced. In addition, our efforts to educate the medical community and third-party
payors on the benefits of our product candidates may require significant resources, may be constrained by FDA rules and policies on product promotion,
and may never be successful.

If we cannot compete successfully against other biotechnology and pharmaceutical companies, we may not be successful in developing and
commercializing our technology and our business will suffer.

The biotechnology and pharmaceutical industries are characterized by intense competition and rapid technological advances, both in the U.S. and
internationally. In addition, the competition in the oncology and pain management markets, and other relevant markets, is intense.  Even if we are able to
develop our product candidates, proprietary platform technology and/or additional antibody libraries, each will compete with a number of existing and
future technologies and product candidates developed, manufactured and marketed by others. Specifically, we will compete against fully integrated
pharmaceutical companies and smaller companies that are collaborating with larger pharmaceutical companies, academic institutions, government agencies
and other public and private research organizations. Many of these competitors have validated technologies with products already FDA-approved or in
various stages of development. In addition, many of these competitors, either alone or together with their collaborative partners, operate larger research and
development programs and have substantially greater financial resources than we do, as well as significantly greater experience in:

•

•

•

developing product candidates and technologies generally;

undertaking preclinical testing and clinical trials;

obtaining FDA and other regulatory approvals of product candidates;

38

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
•

•

formulating and manufacturing product candidates; and

launching, marketing and selling product candidates.

Many of our competitors have substantially greater financial, technical and other resources, such as larger research and development staff and

experienced marketing and manufacturing organizations. Additional mergers and acquisitions in the biotechnology and pharmaceutical industries may
result in even more resources being concentrated in our competitors. As a result, these companies may obtain regulatory approval more rapidly than we are
able and may be more effective in selling and marketing their products as well. Smaller or early-stage companies or generic or biosimilar pharmaceutical
manufacturers may also prove to be significant competitors, particularly through collaborative arrangements with large, established companies.
Competition may increase further as a result of advances in the commercial applicability of technologies and greater availability of capital for investment in
these industries. Our competitors may succeed in developing, acquiring or licensing on an exclusive basis drug products that are more effective or less
costly than any drug candidate that we are currently developing or that we may develop. If approved, our product candidates will face competition from
commercially available drugs as well as drugs that are in the development pipelines of our competitors and later enter the market.

Established pharmaceutical companies may invest heavily to accelerate discovery and development of novel compounds or to in-license novel

compounds that could make our product candidates less competitive. In addition, any new product that competes with an approved product must
demonstrate compelling advantages in efficacy, convenience, tolerability and safety in order to overcome price competition and to be commercially
successful. Accordingly, our competitors may succeed in obtaining patent protection, receiving FDA, MHRA, EMA or other regulatory approval or
discovering, developing and commercializing medicines before we do, which would have a material adverse impact on our business. If our technologies
fail to compete effectively against third party technologies, our business will be adversely impacted.

We expect that our ability to compete effectively will depend upon our ability to:

•

•

•

•

•

successfully and efficiently complete clinical trials and submit for and obtain all requisite regulatory approvals in a cost-effective manner;

obtain and maintain a proprietary position for our products and manufacturing processes and other related product technology;

attract and retain key personnel;

develop relationships with physicians prescribing these products; and

build an adequate sales and marketing infrastructure for our product candidates.

Because we will be competing against significantly larger companies with established track records, we will have to demonstrate that, based on

experience, clinical data, side-effect profiles and other factors, our product candidates, if approved, are competitive with other products.

Reimbursement may be limited or unavailable in certain market segments for our product candidates, which could make it difficult for us to sell our
products profitably.

There is significant uncertainty related to the third-party coverage and reimbursement of newly approved drugs. We intend to seek approval to

market our product candidates in the U.S., Europe and other selected foreign jurisdictions. Market acceptance and sales of our product candidates in both
domestic and international markets will depend significantly on the availability of adequate coverage and reimbursement from third-party payors for any of
our product candidates and may be affected by existing and future health care reform measures. Government and other third-party payors are increasingly
attempting to contain healthcare costs by limiting both coverage and the level of reimbursement for new drugs and, as a result, they may not cover or
provide adequate payment for our product candidates. These payors may conclude that our product candidates are less safe, less effective or less cost-
effective than existing or future introduced products, and third-party payors may not approve our product candidates for coverage and reimbursement or
may cease providing coverage and reimbursement for these product candidates.

Obtaining coverage and reimbursement approval for a product from a government or other third-party payor is a time consuming and costly process

that could require us to provide to the payor supporting scientific, clinical and cost-effectiveness data for the use of our products. We may not be able to
provide data sufficient to gain acceptance with respect to coverage and reimbursement. If reimbursement of our future products is unavailable or limited in
scope or amount, or if pricing is set at unsatisfactory levels, we may be unable to achieve or sustain profitability.

39

 
 
 
 
 
 
 
 
In some foreign countries, particularly in 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
candidate. To obtain reimbursement or pricing approval in some countries, we may be required to conduct additional clinical trials that compare the cost-
effectiveness of our product candidates to other available therapies. If reimbursement of our product candidates is unavailable or limited in scope or amount
in a particular country, or if pricing is set at unsatisfactory levels, we may be unable to achieve or sustain profitability of our products in such country.

Price controls may be imposed, which may adversely affect our future profitability.

In some countries, including member states of the European Union (the “EU”), the pricing of prescription pharmaceuticals is subject to

governmental control. In these countries, pricing negotiations with governmental authorities can take a significant amount of time after receipt of marketing
approval for a product. In addition, there can be considerable pressure by governments and other stakeholders on prices and reimbursement levels,
including as part of cost containment measures. Political, economic and regulatory developments may further complicate pricing negotiations, and pricing
negotiations may continue after reimbursement has been obtained. Reference pricing used by various EU member states and parallel distribution, or
arbitrage between low-priced and high-priced member states, can further reduce prices, and in certain instances render commercialization in certain
markets infeasible or disadvantageous from a financial perspective. In some countries, we or our collaborators may be required to conduct a clinical trial or
other studies that compare the cost-effectiveness of our product and/or our product candidates to other available products in order to obtain or maintain
reimbursement or pricing approval. Publication of discounts by third party payors or government authorities may lead to further pressure on the prices or
reimbursement levels. If reimbursement of our products is unavailable or limited in scope or amount, or if pricing is set at unsatisfactory levels, the
commercial launch of our product and/or product candidates could be delayed, possibly for lengthy periods of time, we or our collaborators may not launch
at all in a particular country, we may not be able to recoup our investment in one or more product candidates, and there could be a material adverse effect
on our business.

Recently, there has been considerable public and government scrutiny in the United States of pharmaceutical pricing and proposals to address the

perceived high cost of pharmaceuticals. There have also been several recent state legislative efforts to address drug costs, which generally have focused on
increasing transparency around drug costs or limiting drug prices or price increases. Adoption of new legislation at the federal or state level could affect
demand for, or pricing of, our product candidates, if approved, and could diminish our ability to establish what we believe is a fair price for our products,
ultimately diminishing our revenue for our products if they are approved.

Healthcare reform measures could hinder or prevent our product candidates’ commercial success.

In both the U.S. and certain foreign jurisdictions, there have been, and we expect there will continue to be a number of legislative and regulatory
changes to the health care system that could impact our ability to sell our products profitably. The U.S. government and other governments have shown
significant interest in pursuing healthcare reform. In particular, the Medicare Modernization Act of 2003 revised the payment methodology for many
products under the Medicare program in the U.S. This has resulted in lower rates of reimbursement. In 2010, the Patient Protection and Affordable Care
Act, as amended by the Health Care and Education Reconciliation Act (collectively, the “Healthcare Reform Law”), was enacted. The Healthcare Reform
Law substantially changed the way healthcare is financed by both governmental and private insurers. Such government-adopted reform measures may
adversely impact the pricing of healthcare products and services in the U.S. or internationally and the amount of reimbursement available from
governmental agencies or other third-party payors.

There have been, and likely will continue to be, legislative and regulatory proposals at the federal and state levels directed at broadening the
availability of healthcare and containing or lowering the cost of healthcare. For example, there have been public announcements by members of the U.S.
Congress regarding their plans to repeal and replace the Healthcare Reform Law and Medicare, and the Biden administration has announced plans to
amend and expand the scope of the Healthcare Reform Law. Although we cannot predict the ultimate content or timing of any healthcare reform
legislation, potential changes resulting from any amendment, repeal, replacement or expansion of these programs, including any reduction in the future
availability of healthcare insurance benefits, could adversely affect our business and future results of operations. The continuing efforts of the government,
insurance companies, managed care organizations and other payors of healthcare services to contain or reduce costs of healthcare may adversely affect the
demand for any product candidates for which we may obtain regulatory approval, as well as our ability to set satisfactory prices for our products, to
generate revenues, and to achieve and maintain profitability.

Failure to successfully validate, develop and obtain regulatory approval for companion diagnostics could harm our long-term drug development
strategy.

As one of the key elements of our clinical development strategy, we seek to identify patients within a disease category or indication who may derive
selective and meaningful benefit from the product candidates we are developing. In collaboration with partners, we plan to develop companion diagnostics
to help us to more accurately identify patients within a particular category or indication, both during our clinical trials and in connection with the
commercialization of certain of our product candidates.

40

 
Companion diagnostics are subject to regulation by the FDA and comparable foreign regulatory authorities as medical devices and require separate
regulatory approval prior to commercialization. We typically do not develop companion diagnostics internally and thus we are dependent on the sustained
cooperation and effort of our third-party collaborators in developing and obtaining approval for these companion diagnostics. We and our collaborators may
encounter difficulties in developing and obtaining approval for the companion diagnostics, including issues relating to selectivity/specificity, analytical
validation, reproducibility or clinical validation. Any delay or failure by our collaborators to develop or obtain regulatory approval of the companion
diagnostics could delay or prevent approval of our product candidates. In addition, our collaborators may encounter production difficulties that could
constrain the supply of the companion diagnostics, and both they and we may have difficulties gaining acceptance of the use of the companion diagnostics
in the clinical community. If such companion diagnostics fail to gain market acceptance, it would have an adverse effect on our ability to derive revenues
from sales of our products. In addition, any diagnostic company with whom we contract may decide to discontinue selling or manufacturing the companion
diagnostic that we anticipate using in connection with development and commercialization of our product candidates or our relationship with such
diagnostic company may otherwise terminate. In such instances, we may not be able to enter into arrangements with another diagnostic company to obtain
supplies of an alternative diagnostic test for use in connection with the development and commercialization of our product candidates or do so on
commercially reasonable terms, which could adversely affect and/or delay the development or commercialization of our product candidates.

Our collaborations depend upon the efforts of third parties to fund and manage the development of many of our potential product candidates, and
failure of those third-party collaborators to assist or share in the costs of product development could materially harm our business, financial condition
and results of operations.

Our strategy for the development and commercialization of our proprietary product candidates has included the formation of joint ventures and

collaborative arrangements with third parties. Potential third parties include biopharmaceutical, pharmaceutical and biotechnology companies, academic
institutions and other entities. Third-party collaborators may assist us in:

•

•

•

•

funding research, preclinical development, clinical trials and manufacturing;

seeking and obtaining regulatory approvals;

seeking and obtaining intellectual property and/or other proprietary rights to technology; and  

successfully commercializing any future product candidates.

Our collaborations limit our ability to control the efforts devoted to many of our product candidates in such arrangements and our earlier stage
pipeline is dependent upon identifying new potential collaborators.  For example, our most recent joint ventures require us to conduct research and provide
potential product candidates in addition to making capital contributions to continue the further development of those products. We generally do not have
control over the management of the joint ventures and are minority holders in most of those ventures, which may result in limitations on our ability to
successfully develop product candidates, obtain intellectual property and/or other proprietary rights and fund clinical trials through those joint ventures.  

In addition, if we are not able to establish further collaboration agreements, we may be required to undertake product development and
commercialization at our own expense. Such an undertaking may limit the number of product candidates that we will be able to develop, significantly
increase our capital requirements and place additional strain on our internal resources.

Our failure to enter into additional collaborations could materially harm our business, financial condition and results of operations.

In addition, our dependence on licensing, collaboration and other agreements with third parties may subject us to a number of risks. These

agreements may not be on terms that prove favorable to us and may require us to relinquish certain rights in our product candidates. To the extent we agree
to work exclusively with one collaborator in a given area, our opportunities to collaborate with other entities could be curtailed. Lengthy negotiations with
potential new collaborators may lead to delays in the research, development or commercialization of product candidates. The decision by our collaborators
to pursue alternative technologies or the failure of our collaborators to develop or commercialize successfully any product candidate to which they have
obtained rights from us could materially harm our business, financial condition and results of operations.

We may seek to establish collaborations and, if we are not able to establish them on commercially reasonable terms, we may have to alter our
development and commercialization plans.

From time to time we may engage in efforts to enter into licensing, distribution and/or collaboration agreements with one or more pharmaceutical or
biotechnology companies to assist us with development and/or commercialization of our other product candidates. If we are successful in entering into such
agreements, we may not be able to negotiate agreements with economic terms similar to those negotiated by other companies. We may not, for example,
obtain significant upfront payments, substantial royalty

41

 
 
 
 
 
rates or milestones. If we fail to enter into any such agreements in a timely manner or at all, our efforts to develop and/or commercialize our product
candidates may be undermined. In addition, if we do not raise funds through any such agreements, we will need to rely on other financing mechanisms,
such as sales of debt or equity securities, to fund our operations. Such financing mechanisms, if available, may not be sufficient or timely enough to
advance our programs forward in a meaningful way in the short-term.

We may not be successful in entering into additional collaborations as a result of many factors, including the following:

•

•

•

•

•

•

•

competition in seeking appropriate collaborators;

a reduced number of potential collaborators due to recent business combinations in the pharmaceutical industry;

inability to negotiate collaborations on acceptable terms;

inability to negotiate collaborations on a timely basis;

a potential collaborator’s evaluation of our product or product candidates;

a potential collaborator’s resources and expertise; and

restrictions due to an existing collaboration agreement.

If we are unable to enter into collaborations, we may have to curtail the commercialization or the development of any product candidate on which

we are seeking to collaborate, reduce or delay its development program or those for other 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. 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 develop
or commercialize our product candidates.

Even if we enter into collaboration agreements and strategic partnerships or license our intellectual property, we may not be able to maintain them or

they may be unsuccessful, which could delay our timelines or otherwise adversely affect our business.

We, as well as any collaborators or licensees of our technologies and services, will not be able to commercialize our product candidates if preclinical
studies do not produce successful results or clinical trials do not demonstrate safety and efficacy in humans.

Preclinical and clinical testing is expensive, difficult to design and implement, can take many years to complete and have an uncertain outcome.

Success in preclinical testing and early clinical trials does not ensure that later clinical trials will be successful, and interim results of a clinical trial do not
necessarily predict final results. We, as well as any licensees and collaborators, may experience numerous unforeseen events during, or as a result of,
preclinical testing and the clinical trial process that could delay or prevent the commercialization of product candidates based on our technologies,
including the following:

•

•

•

Preclinical or clinical trials may produce negative or inconclusive results, which may require additional preclinical testing, additional clinical
trials or the abandonment of projects that we, our licensees or our collaborators expect to be promising. For example, promising animal data
may be obtained about the anticipated efficacy of a product candidate and then human tests may not result in such an effect. In addition,
unexpected safety concerns may be encountered that would require further testing even if the product candidate produced an otherwise
favorable response in human subjects.

Initial clinical results may not be supported by further or more extensive clinical trials. For example, we or a licensee may obtain data that
suggest a desirable response from a product candidate in a small human study, but when tests are conducted on larger numbers of people, the
same extent of response may not occur. If the response generated by a product candidate is too low or occurs in too few treated individuals,
then the product candidate will have no commercial value.

Enrollment in any of our or any of our licensee’s or collaborator’s clinical trials may be slower than projected, resulting in significant delays.
The cost of conducting a clinical trial increases as the time required to enroll adequate numbers of human subjects to obtain meaningful
results increases. Enrollment in a clinical trial can be a slower-than-anticipated process because of competition from other clinical trials,
because the study is not of interest to qualified subjects, or because the stringency of requirements for enrollment limits the number of people
who are eligible to participate in the clinical trial.

42

 
 
 
 
 
 
 
 
 
 
 
•

•

•

We, our licensees or our collaborators might have to suspend or terminate clinical trials if the participating subjects are being exposed to
unacceptable health risks. Animal tests do not always adequately predict potential safety risks to human subjects. The risk of any product
candidate is unknown until it is tested in human subjects, and if subjects experience adverse events during the clinical trial, the trial may have
to be suspended and modified or terminated entirely.

Regulators or institutional review boards may suspend or terminate clinical research for various reasons, including safety concerns or
noncompliance with regulatory requirements.

Any regulatory approval ultimately obtained may be limited or subject to restrictions or post-approval commitments that render the product
not commercially viable.

The effects of our technology-derived or technology-enhanced product candidates may not be the desired effects or may include undesirable
side effects.

Significant clinical trial delays could allow our competitors to bring products to market before we, any of our licensees or our collaborators do and

impair our ability to commercialize our technologies and product candidates based on our technologies. Poor clinical trial results or delays may make it
impossible to license a product candidate or so reduce its attractiveness to prospective licensees that we will be unable to successfully develop and
commercialize such a product candidate.

Because our development activities are expected to rely heavily on sensitive and personal information, an area which is highly regulated by privacy
laws, we may not be able to generate, maintain or access essential patient samples or data to continue our research and development efforts in the
future on reasonable terms and conditions, which may adversely affect our business.

Although we are not subject to the Health Insurance Portability and Accountability Act of 1996 (“HIPAA”), as we are neither a Covered Entity nor

Business Associate (as defined in HIPAA and the Health Information Technology and Clinical Health Act (the “HITECH Act”)), we may have access to
very sensitive data regarding patients whose tissue samples are used in our studies. This data will contain information that is personal in nature. The
maintenance of this data is subject to certain privacy-related laws, which impose upon us administrative and financial burdens, and litigation risks. In the
United States, numerous federal and state laws and regulations, including state data breach notification laws, state health information privacy laws and
federal and state consumer protection laws govern the collection, use, disclosure and protection of health-related and other personal information. For
instance, the rules promulgated by the Department of Health and Human Services under HIPAA create national standards to protect patients’ medical
records and other personal information in the U.S. These rules require that healthcare providers and other covered entities obtain written authorizations
from patients prior to disclosing protected health care information of the patient to companies. If the patient fails to execute an authorization or the
authorization fails to contain all required provisions, then we will not be allowed access to the patient’s information and our research efforts can be
substantially delayed. Furthermore, use of protected health information that is provided to us pursuant to a valid patient authorization is subject to the limits
set forth in the authorization (i.e., for use in research and in submissions to regulatory authorities for product approvals). As such, we are required to
implement policies, procedures and reasonable and appropriate security measures to protect individually identifiable health information we receive from
covered entities, and to ensure such information is used only as authorized by the patient. Any violations of these rules by us could subject us to civil and
criminal penalties and adverse publicity and could harm our ability to initiate and complete clinical trials required to support regulatory applications for our
product candidates. In addition, HIPAA does not replace federal, state, or other laws that may grant individuals even greater privacy protections.

California recently enacted the California Consumer Privacy Act (“CCPA”), which creates new individual privacy rights for California consumers

and places increased privacy and security obligations on entities handling personal data of consumers or households. The CCPA requires covered
companies to provide new disclosure to consumers about such companies’ data collection, use and sharing practices, provide such consumers new ways to
opt-out of certain sales or transfers of personal information, and provide consumers with additional causes of action. The CCPA went into effect on January
1, 2020, and beginning July 1, 2020, the California Attorney General may bring enforcement actions for violations. The CCPA, among other things,
requires covered companies to provide disclosures to California consumers concerning the collection and sale of personal information, and will give such
consumers the right to opt-out of certain sales of personal information. The CCPA may increase our company`s compliance costs and potential liability, and
we cannot yet predict the impact of the CCPA on our business.

43

 
 
 
 
 
International data protection laws, including Regulation 2016/679, known as the General Data Protection Regulation (“GDPR”), may also apply to
health-related and other personal information obtained outside of the United States. The GDPR went into effect on May 25, 2018. The GDPR strengthened
data protection requirements in the European Union, as well as potential fines for noncompliant companies of up to the greater of €20 million or 4% of
annual global revenue. The regulation imposes numerous new requirements for the collection, use, storage and disclosure of personal information,
including more stringent requirements relating to consent and the information that must be shared with data subjects about how their personal information
is used, the obligation to notify regulators and affected individuals of personal data breaches, extensive new internal privacy governance obligations and
obligations to honor expanded rights of individuals in relation to their personal information, including the right to access, correct and delete their data. In
addition, the GDPR includes restrictions on cross-border data transfers. The GDPR increased our responsibility and liability in relation to personal data that
we process where such processing is subject to the GDPR, and we may be required to put in place additional mechanisms to ensure compliance with the
GDPR, including as implemented by individual countries. Further, the United Kingdom’s exit from the European Union, often referred to as Brexit, has
created uncertainty with regard to data protection regulation in the United Kingdom. In particular, it is unclear how data transfers to and from the United
Kingdom will be regulated.

Failure to comply with data protection laws and regulations could result in government enforcement actions, which may involve civil and criminal

penalties, private litigation and/or adverse publicity and could negatively affect our operating results and business. Claims that we have violated
individuals’ privacy rights or breached our contractual obligations, even if we are not found liable, could be expensive and time-consuming to defend and
could result in adverse publicity that could harm our business.

We can provide no assurance that future legislation will not prevent us from generating or maintaining personal data or that patients will consent to
the use of their personal information, either of which may prevent us from undertaking or publishing essential research. These burdens or risks may prove
too great for us to reasonably bear and may adversely affect our ability to achieve profitability or maintain profitably in the future.

Our therapeutic product candidates for which we intend to seek approval as biological products may face competition sooner than expected.

With the enactment of the Biologics Price Competition and Innovation Act of 2009 (“BPCIA”) as part of the Health Care Reform Law, an
abbreviated pathway for the approval of biosimilar and interchangeable biological products was created. The new abbreviated regulatory pathway
establishes legal authority for the FDA to review and approve biosimilar biologics, including the possible designation of a biosimilar as “interchangeable.”
The FDA defines an interchangeable biosimilar as a product that, in terms of safety or diminished efficacy, presents no greater risk when switching between
the biosimilar and its reference product than the risk of using the reference product alone. Under the BPCIA, an application for a biosimilar product cannot
be submitted to the FDA until four years, or approved by the FDA until 12 years, after the original brand product identified as the reference product was
approved under a BLA. The new law is complex and is only beginning to be interpreted by the FDA. As a result, its ultimate impact, implementation and
meaning are subject to uncertainty. While it is uncertain when any such processes may be fully adopted by the FDA, any such processes could have a
material adverse effect on the future commercial prospects for our biological products.

Although we believe that if any of our product candidates were to be approved as biological products under a BLA, such approved products should
qualify for the 12-year period of exclusivity, there is a risk that the U.S. Congress could amend the BPCIA to significantly shorten this exclusivity period,
potentially creating the opportunity for generic competition sooner than anticipated. Moreover, the extent to which a biosimilar, once approved, will be
substituted for any one of our reference products in a way that is similar to traditional generic substitution for non-biological products is not yet clear, and
will depend on a number of marketplace and regulatory factors that are still developing. In addition, a competitor could decide to forego the biosimilar
route and submit a full BLA after completing its own preclinical studies and clinical trials. In such cases, any exclusivity to which we may be eligible under
the BPCIA would not prevent the competitor from marketing its product as soon as it is approved.

44

 
The regulatory path forward for biosimilar/biobetter product candidates is not clear.

We have acquired and are assessing the regulatory and strategic path forward for our portfolio of late stage biosimilar/biobetter antibodies based on

Erbitux®, Remicade®, Xolair® and Simulect®. While the enactment of the BPCIA created an abbreviated pathway for the approval of biosimilar and
interchangeable biological products, there is still considerable uncertainty with respect to the FDA’s approval process. While applications based on
biosimilarity may not be required to duplicate the entirety of preclinical and clinical testing used to establish the underlying safety and effectiveness of the
reference product, the FDA may refuse to approve an application if there is insufficient information to show that the active ingredients are the same or to
demonstrate that any impurities or differences in active ingredients do not affect the safety, purity or potency of the product. In addition, applications based
on biosimilarity will not be approved unless the product is manufactured in facilities designed to assure and preserve the biological product’s safety, purity
and potency. Due to the uncertainty surrounding the approval of biosimilar/biobetter products, as well as other risk factors identified in this Annual Report
on Form 10-K, our portfolio of late stage biosimilar/biobetter antibodies may never result in commercially viable products.

We may be exposed to liability claims associated with the use of hazardous materials and chemicals.

Our research and development activities may involve the controlled use of hazardous materials and chemicals. Although we believe that our safety
procedures for using, storing, handling and disposing of these materials comply with federal, state and local laws and regulations, we cannot eliminate the
risk of accidental injury or contamination from these materials. In the event of such an accident, we could be held liable for any resulting damages and any
liability could materially adversely affect our business, financial condition and results of operations. We do not currently maintain hazardous materials
insurance coverage. In addition, the federal, state and local laws and regulations governing the use, manufacture, storage, handling and disposal of
hazardous or radioactive materials and waste products may require us to incur substantial compliance costs that could materially harm our business.

If we are unable to retain and recruit qualified scientists and advisors, or if any of our key executives, key employees or key consultants discontinues
his or her employment or consulting relationship with us, it may delay our development efforts or otherwise harm our business.

We may not be able to attract or retain qualified management and scientific and clinical personnel in the future due to the intense competition for

qualified personnel among biotechnology, pharmaceutical and other businesses, particularly in the San Diego, California area. Our industry has experienced
a high rate of turnover of management personnel in recent years. If we are not able to attract, retain and motivate necessary personnel to accomplish our
business objectives, we may experience constraints that will significantly impede the successful development of any product candidates, our ability to raise
additional capital and our ability to implement our overall business strategy. In addition, our CMO operations will depend, in part, on our ability to attract
and retain an appropriately skilled and sufficient workforce to operate our development and manufacturing facilities. The facilities are located in a growing
biotechnology hub and competition for skilled workers will continue to increase as the industry undergoes further growth in the area.

We are highly dependent on key members of our management and scientific staff, especially Henry Ji, Ph.D., Chairman of the Board, Chief

Executive Officer and President. Our success also depends on our ability to continue to attract, retain and motivate highly skilled junior, mid-level and
senior managers as well as junior, mid-level and senior scientific and medical personnel. The loss of any of our executive officers, key employees or key
consultants and our inability to find suitable replacements could impede the achievement of our research and development objectives, and potentially harm
our business, financial condition and prospects. Furthermore, recruiting and retaining qualified scientific personnel to perform research and development
work in the future is critical to our success. We may be unable to attract and retain personnel on acceptable terms given the competition among
biotechnology, biopharmaceutical and health care companies, universities and non-profit research institutions for experienced scientists. Certain of our
current officers, directors, scientific advisors and/or consultants or certain of the officers, directors, scientific advisors and/or consultants hereafter
appointed may from time to time serve as officers, directors, scientific advisors and/or consultants of other biopharmaceutical or biotechnology companies.
We do not maintain “key man” insurance policies on any of our officers or employees. All of our employees are employed “at will” and, therefore, each
employee may leave our employment at any time.

We may not be able to attract or retain qualified management and scientific personnel in the future due to the intense competition for a limited

number of qualified personnel among biopharmaceutical, biotechnology, pharmaceutical and other businesses. Many of the other pharmaceutical
companies that we compete against for qualified personnel have greater financial and other resources, different risk profiles and a longer history in the
industry than we do. They also may provide more diverse opportunities and better chances for career advancement. Some of these characteristics may be
more appealing to high quality candidates than what we have to offer. If we are unable to continue to attract and retain high quality personnel, the rate and
success at which we can develop and commercialize product candidates will be limited.

45

 
We plan to grant stock options or other forms of equity awards in the future as a method of attracting and retaining employees, motivating

performance and aligning the interests of employees with those of our stockholders. If we are unable to implement and maintain equity compensation
arrangements that provide sufficient incentives, we may be unable to retain our existing employees and attract additional qualified candidates. If we are
unable to retain our existing employees, including qualified scientific personnel, and attract additional qualified candidates, our business and results of
operations could be adversely affected.

Our employees may engage in misconduct or other improper activities, including noncompliance with regulatory standards and requirements, which
could have a material adverse effect on our business.

We are exposed to the risk of employee fraud or other misconduct. Misconduct by employees could include intentional failures to comply with FDA
regulations, provide accurate information to the FDA, comply with manufacturing standards we have established, comply with federal and state health-care
fraud and abuse laws and regulations, comply with laws and regulations (including, but not limited to the Foreign Corrupt Practices Act of 1977, as
amended, 15 U.S.C. §§ 78dd-1 (“FCPA”)) and internal policies restricting payments to government agencies and representatives, report financial
information or data accurately or disclose unauthorized activities to us. In particular, sales, marketing and business arrangements in the healthcare industry
are subject to extensive laws and regulations intended to prevent fraud, kickbacks, self-dealing and other abusive practices. These laws and regulations may
restrict or prohibit a wide range of pricing, discounting, marketing and promotion, sales commission, customer incentive programs and other business
arrangements. 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. We have adopted a Code of Business Conduct and Ethics, but 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
or regulations. 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.

We may be subject, directly or indirectly, to federal and state healthcare fraud and abuse laws, false claims laws and health information privacy and
security laws. If we are unable to comply, or have not fully complied, with such laws, we could face substantial penalties.

If we obtain FDA approval for any of our product candidates, as we have with ZTlido through Scilex Pharma, and begin commercializing those

products in the U.S., our operations may be directly, or indirectly through our customers, subject to various federal and state fraud and abuse laws,
including, without limitation, the federal Anti-Kickback Statute and the federal False Claims Act. These laws may impact, among other things, our
proposed sales, marketing and education programs. In addition, we may be subject to patient privacy regulation by both the federal government and the
states in which we conduct our business. The laws that may affect our ability to operate include:

•

•

•

•

•

the federal Anti-Kickback Statute, which prohibits, among other things, persons from knowingly and willfully soliciting, receiving, offering
or paying remuneration, directly or indirectly, to induce, or in return for, the purchase or recommendation of an item or service reimbursable
under a federal healthcare program, such as the Medicare and Medicaid programs;

federal civil and criminal false claims laws and civil monetary penalty laws, which prohibit, among other things, individuals or entities from
knowingly presenting, or causing to be presented, claims for payment from Medicare, Medicaid, or other third-party payers that are false or
fraudulent;

HIPAA, which created new federal criminal statutes that prohibit executing a scheme to defraud any healthcare benefit program and making
false statements relating to healthcare matters;

HIPAA, as amended by the HITECH Act, and its implementing regulations, which imposes certain requirements relating to the privacy,
security and transmission of individually identifiable health information; and

state law equivalents of each of the above federal laws, such as anti-kickback and false claims laws which may apply to items or services
reimbursed by any third-party payer, including commercial insurers, and state laws governing the privacy and security of health information
in certain circumstances, many of which differ from each other in significant ways and may not have the same effect, thus complicating
compliance efforts.

If our operations are found to be in violation of any of the laws described above or any other governmental regulations that apply to us, we may be

subject to penalties, including civil and criminal penalties, damages, fines and the curtailment or restructuring of our operations, any of which could
adversely affect our ability to operate our business and our results of operations.

If product liability lawsuits are brought against us, we may incur substantial liabilities and may be required to limit commercialization of our product
candidates.

We face an inherent risk of product liability as a result of the clinical testing of our product candidates and will face an even greater risk for the

commercialization of any products, including ZTlido, which is marketed and sold through our subsidiary, Scilex Holding. For example, we may be sued if
any product we develop allegedly causes injury or is found to be otherwise unsuitable during product 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, and 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, if
approved. Even successful defense would require significant financial and management resources. 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;

withdrawal of clinical trial participants;

initiation of investigations by regulators;

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

costs to defend the related litigation;

a diversion of management’s time and our resources;

substantial monetary awards to trial participants or patients;

product recalls, withdrawals or labeling, marketing or promotional restrictions;

loss of revenues from product sales; and

the inability to commercialize our product candidates.

In addition, through our contract manufacturing operations, we may manufacture product candidates intended for use in humans. These activities

could expose us to risk of liability for personal injury or death to persons using such product candidates or approved products. We seek to reduce our
potential liability through measures such as contractual indemnification provisions with collaborators (the scope of which may vary by collaborator, and the
performances of which are not secured) and insurance maintained by us and our collaborators. Our business, financial condition and results of operations
could be materially adversely affected if we are required to pay damages or incur defense costs in connection with a claim that is outside the scope of the
indemnification agreements, if the indemnity, although applicable, is not performed in accordance with its terms or if our liabilities exceed the amount of
applicable insurance or indemnity. In addition, we could be held liable for errors and omissions in connection with the services we perform.

Our inability to obtain and retain sufficient product liability insurance at an acceptable cost to protect against potential product liability claims could
prevent or inhibit the commercialization of products we develop. We currently carry product liability insurance and errors and omissions insurance that we
believe is appropriate for our company. Although we maintain product liability insurance, any claim that may be brought against us could result in a court
judgment or settlement in an amount that is not covered, in whole or in part, by our insurance or that is in excess of the limits of our insurance coverage.
Our insurance policies also have various exclusions, and we may be subject to a product liability claim for which we have insufficient or no coverage. If we
have to pay any amounts awarded by a court or negotiated in a settlement that exceed our coverage limitations or that are not covered by our insurance, we
may not have, or be able to obtain, sufficient capital to pay such amounts. In addition, insurance coverage is becoming increasingly expensive, and we may
not be able to maintain insurance coverage at a reasonable cost. We also may not be able to obtain additional insurance coverage that will be adequate to
cover product liability risks that may arise. Consequently, a product liability claim may result in losses that could be material to our business, financial
condition and results of operations.

We are subject to the U.S. Foreign Corrupt Practices Act and other anti-corruption laws, as well as export control laws, customs laws, sanctions laws
and  other  laws  governing  our  operations.  If  we  fail  to  comply  with  these  laws,  we  could  be  subject  to  civil  or  criminal  penalties,  other  remedial
measures, and legal expenses, which could adversely affect our business, results of operations and financial condition.

Our operations are subject to certain anti-corruption laws, including the FCPA, the UK Bribery Act and other anti-corruption laws that apply in

countries where we do business. The FCPA and other anti-corruption laws generally prohibit us and our employees

47

 
 
 
 
 
 
 
 
 
 
 
 
and intermediaries from bribing, being bribed or making other prohibited payments to government officials or other persons to obtain or retain business or
gain some other business advantage. We and our commercial partners operate in a number of jurisdictions that pose a high risk of potential FCPA violations
and we participate in collaborations and relationships with third parties whose actions could potentially subject us to liability under the FCPA or local anti-
corruption laws. In addition, we cannot predict the nature, scope or effect of future regulatory requirements to which our international operations might be
subject or the manner in which existing laws might be administered or interpreted.

We are also subject to other laws and regulations governing our international operations, including regulations administered in the U.S. and in the

EU, including applicable import and export control regulations such as those regulations under the Convention on International Trade in Endangered
Species of Wild Fauna and Flora, also known as the Washington Convention (“CITES”), economic sanctions on countries and persons, customs
requirements and currency exchange regulations (collectively, “Trade Control Laws”).

There can be no assurance that we will be completely effective in ensuring our compliance with all applicable anticorruption laws, including the

FCPA or other legal requirements, such as Trade Control Laws. Any investigation of potential violations of the FCPA, other anti-corruption laws or Trade
Control Laws by U.S., EU or other authorities could have an adverse impact on our reputation, our business, results of operations and financial condition.
Furthermore, should we be found not to be in compliance with the FCPA, other anti-corruption laws or Trade Control Laws, we may be subject to criminal
and civil penalties, disgorgement and other sanctions and remedial measures, as well as the accompanying legal expenses, any of which could have a
material adverse effect on our reputation and liquidity, as well as on our business, results of operations and financial condition.

Federal  regulation  and  enforcement  may  adversely  affect  the  implementation  of  cannabis  laws,  and  such  regulations  may  negatively  impact  our
business operations, revenues and profits.

As previously disclosed, we have formed a Chinese joint venture with LifeTech Scientific Co., Ltd. to commercialize our proprietary water soluble

cannabidiol (“CBD”) formulation technologies for consumer and pharmaceutical applications in Asia (excluding Japan). We have also formed a new
business unit, Scintilla Health, Inc., to explore commercial opportunities of our water-soluble CBD formulation technologies for both consumer and
pharmaceutical applications in North America, Europe and other parts of the world.

Currently, there are over 30 states in the United States, plus the District of Columbia, that have laws and/or regulations that recognize, in one form
or another, medical benefits or other uses for CBD infused or cannabis related products. These states have also passed laws governing the use and sale of
cannabis products and others are considering similar legislation. Nonetheless, at least some provisions of these state laws are in direct conflict with the
United States Federal Controlled Substances Act (21 U.S.C. § 811) (“CSA”), which places controlled substances, including cannabis, in a schedule.
Cannabis is classified as a Schedule I drug, which is viewed as having a high potential for abuse, has no currently-accepted use for medical treatment in the
U.S., and lacks acceptable safety for use under medical supervision. Under the CSA, the policies and regulations of the federal government and its agencies
are that cannabis has no medical benefit and a range of activities including cultivation and the personal use of cannabis is prohibited.

Uncertainty remains the rule under the CSA. There is disagreement between the government and the courts regarding the precise scope of the CSA.

Some courts have held that CBD is excluded from the CSA, which they believe, only covers the Tetrahydrocannabinol (“THC”) chemical. Others have held
that CBD is covered by the CSA when it is derived from the cannabis plant. On December 20, 2018, the Agricultural Improvement Act of 2018 (the “2018
Farm Bill”) legalized the cultivation and production of hemp, a variation on the cannabis plant that contains CBD but less than 0.3% THC (the
psychoactive chemical of the cannabis plant), providing at least some certainty about sources of legal CBD. Our water-soluble CBD formulation
technologies are expected to utilize hemp.

Unless and until Congress amends the CSA to clarify precisely what is covered by the CSA, there is a risk that federal authorities may enforce
current federal law against us despite our efforts to source our products from legal sources, and we may be deemed to be producing and/or dispensing
marijuana-based products in violation of federal law. There is no assurance as to the timing or scope of any such potential amendment to the CSA. Active
enforcement of the current federal regulatory position on cannabis may thus directly or indirectly, and adversely, affect our business, operations, revenues
and any profits. The risk of strict enforcement of the CSA in light of Congressional activity, judicial holdings and stated federal policy remains uncertain.

The Department of Justice (“DOJ”) has not historically devoted resources to prosecuting individuals whose conduct is limited to possession of small

amounts of marijuana for use on private property and has instead relied on state and local law enforcement to address marijuana activity. In the event the
DOJ reverses its stated policy and begins strict enforcement of the CSA in states that have laws legalizing medical marijuana and recreational marijuana in
small amounts, there may be a direct and adverse impact to our business and our revenue and profits. Furthermore, H.R. 83, enacted by Congress on
December 16, 2014, provides that none of the funds made available to the DOJ pursuant to the 2015 Consolidated and Further Continuing Appropriations
Act may be used to

48

 
prevent certain states from implementing their own laws that authorized the use, distribution, possession or cultivation of medical marijuana.

Under the 2018 Farm Bill, the FDA has been given the authority to regulate CBD when incorporated into a food, drug or cosmetic substance.
Immediately following the passage of the 2018 Farm Bill, the FDA signaled its intent to use this power. On May 31, 2019, the FDA held public hearings to
obtain scientific data and information about the safety, manufacturing, product quality, marketing, labeling and sale of products containing cannabis or
cannabis-derived compounds, including CBD. Currently, the FDA has not issued any guidance, rules or regulations regarding the use of CBD in foods,
drugs or cosmetics. Because our water-soluble CBD formulation technologies may be used to produce CBD for inclusion in food or beverages, any FDA
rules and regulations limiting our ability to source, manufacture and sell CBD products, or limiting the consumer’s ability to purchase and use the products,
could have a material adverse effect on our business, financial condition and results of operations.

We will need to increase the size of our company and may not effectively manage our growth.

Our success will depend upon growing our business and our employee base. Over the next 12 months, we plan to add additional employees to assist
us with research and development and our commercialization efforts. Our future growth, if any, may cause a significant strain on our management, and our
operational, financial and other resources. Our ability to manage our growth effectively will require us to implement and improve our operational, financial
and management systems and to expand, train, manage and motivate our employees. These demands may require the hiring of additional management
personnel and the development of additional expertise by management. Any increase in resources devoted to research and product development without a
corresponding increase in our operational, financial and management systems could have a material adverse effect on our business, financial condition, and
results of operations.

A fast track product designation or other designation to facilitate product candidate development may not lead to faster development or regulatory
review or approval process, and it does not increase the likelihood that our product candidates will receive marketing approval.

A product sponsor may apply for fast track designation from the FDA if a product is intended for the treatment of a serious or life-threatening

condition and preclinical or clinical data demonstrate the potential to address an unmet medical need for this condition (“Fast Track Designation”). The
FDA has broad discretion whether or not to grant this designation. We have received Fast Track Designation for SEMDEXATM, which is in development
for the treatment of lumbosacral radicular pain. Even though SEMDEXATM has received Fast Track Designation, we may not experience a faster process,
review or approval compared to conventional FDA procedures. Fast Track Designation does not accelerate clinical trials, mean that regulatory requirements
are less stringent or provide assurance of ultimate marketing approval by the FDA. Instead, Fast Track Designation provides opportunities for frequent
interactions with FDA review staff, as well as eligibility for priority review, if relevant criteria are met, and rolling review. The FDA may rescind the fast
track designation if it believes that the designation is no longer supported by data from our clinical development program. The FDA may also withdraw any
fast track designation at any time.

Drug development involves a lengthy and expensive process with an uncertain outcome, and results of earlier studies and trials may not be predictive of
future trial results.

Clinical testing is expensive and can take many years to complete, and its outcome is risky and uncertain. Failure can occur at any time during the
clinical trial process. The results of preclinical studies and early clinical trials of our product candidates may not be predictive of the results of later-stage
clinical trials. Product candidates in later stages of clinical trials may fail to show the desired safety and efficacy traits despite having progressed through
preclinical studies and initial clinical trials. It is not uncommon for companies in the pharmaceutical industry to suffer significant setbacks in advanced
clinical trials due to lack of efficacy or adverse safety profiles, notwithstanding promising results in earlier trials. Our future clinical trial results may not be
successful.

This drug candidate development risk is heightened by any changes in the planned clinical trials compared to the completed clinical trials. As

product candidates are developed through preclinical to early and late stage clinical trials towards approval and commercialization, it is customary that
various aspects of the development program, such as manufacturing and methods of administration, are altered along the way in an effort to optimize
processes and results. While these types of changes are common and are intended to optimize the product candidates for late stage clinical trials, approval
and commercialization, such changes do carry the risk that they will not achieve these intended objectives.

Other than with respect to ZTlido, we have not completed a corporate-sponsored clinical trial. Phase I trials are ongoing for RTX for knee

osteoarthritis, RTX for cancer-related pain and anti-CD38 CAR-T for multiple myeloma a Phase III trial is ongoing for SEMDEXATM for the treatment of
lumbosacral radicular pain. Non-clinical studies are ongoing and a Phase II trial is planned to start

49

 
in the first half of 2021 with higher strength SP-103. We are currently in a Phase II study of abivertinib for cytokine storm related to COVID-19 infection, a
Phase I study of mesenchymal stem cells for the treatment of respiratory distress syndrome associated with COVID-19 infection and a Phase I study of
COVI-GUARD in hospitalized patients with COVID-19. Despite this, we may not have the necessary capabilities, including adequate staffing, to
successfully manage the execution and completion of any clinical trials we initiate, including our planned clinical trials of RTX, clinical trials of SP-103,
clinical trials of SEMDEXATM, clinical trials of CAR-T, including targeting CD38 using a CAR-T cell therapy, our biosimilar/biobetters antibodies,
clinical trials of our COVID-19 related product candidates and other product candidates, in a way that leads to our obtaining marketing approval for our
product candidates in a timely manner, or at all.

In the event we are able to conduct a pivotal clinical trial of a product candidate, the results of such trial may not be adequate to support marketing
approval. Because our product candidates are intended for use in life-threatening diseases, in some cases we ultimately intend to seek marketing approval
for each product candidate based on the results of a single pivotal clinical trial. As a result, these trials may receive enhanced scrutiny from the FDA. For
any such pivotal trial, if the FDA disagrees with our choice of primary endpoint or the results for the primary endpoint are not robust or significant relative
to control, are subject to confounding factors, or are not adequately supported by other study endpoints, including possibly overall survival or complete
response rate, the FDA may refuse to approve a NDA, Biologics License Application or other application for marketing based on such pivotal trial. The
FDA may require additional clinical trials as a condition for approving our product candidates.

There can be no assurance that the product candidates we are developing for the detection and treatment of COVID-19 will be granted an Emergency
Use Authorization by the FDA. If no Emergency Use Authorization is granted or, once granted, it is terminated, we will be unable to sell our product
candidates in the near future and will be required to pursue the drug approval process, which is lengthy and expensive.

On June 10, 2020, we announced the submission of an Emergency Use Authorization (“EUA”) to the FDA for our COVI-TRACK in vitro
diagnostic test kit for the independent detection of IgG and IgM antibodies in sera of patients exposed to the SARS-CoV-2 virus. On December 22, 2020,
we announced the submission of an EUA to the FDA for COVI-STIX, our rapid diagnostic test for the detection of the SARS-CoV-2 virus nucleocapsid
antigen in nasal samples of patients.

An EUA would allow us to market and sell COVI-TRACK or COVI-STIX without the need to pursue the lengthy and expensive drug approval

process. The FDA may issue an EUA during a public health emergency if it determines that the potential benefits of a product outweigh the potential risks
and if other regulatory criteria are met. If an EUA is granted for COVI-TRACK or COVI-STIX, we will rely on the FDA policies and guidance in
connection with the marketing and sale of COVI-TRACK or COVI-STIX, respectively. If these policies and guidance change unexpectedly and/or
materially or if we misinterpret them, potential sales of COVI-TRACK or COVI-STIX could be adversely impacted. In addition, the FDA may revoke an
EUA where it is determined that the underlying health emergency no longer exists or warrants such authorization. If granted, we cannot predict how long
an EUA for COVI-TRACK or COVI-STIX will remain in place. If an EUA for COVI-TRACK or COVI-STIX is granted but subsequently terminated,
such termination, could adversely impact our business, financial condition and results of operations.

We may also seek additional EUAs from the FDA for our other product candidates for the detection and/or treatment of COVID-19 and the SARS-

CoV-2 virus. If granted, the additional EUAs would allow us to market and sell additional product candidates without the need to pursue the lengthy and
expensive drug approval process. There is no guarantee that we will be able to obtain any additional EUAs. Failure to obtain additional EUAs or the
termination of such EUAs, if obtained, could adversely impact our business, financial condition and results of operations.

Interim  “top-line”  and  preliminary  data  from  our  clinical  trials  that  we  announce  or  publish  from  time  to  time  may  change  as  more  patient  data
become available and are subject to audit and verification procedures that could result in material changes in the final data.

From time to time, we may publish interim “top-line” or preliminary data from our clinical trials, which is based on a preliminary analysis of then-
available data, and the results and related findings and conclusions are subject to change following a more comprehensive review of the data related to the
particular study. We also make assumptions, estimations, calculations and conclusions as part of our analyses of data, and we may not have received or had
the opportunity to fully and carefully evaluate all data. As a result, the topline results that we report may differ from future results of the same studies, or
different conclusions or considerations may qualify such results, once additional data have been received and fully evaluated. Preliminary or interim data
from clinical trials that we may complete are subject to the risk that one or more of the clinical outcomes may materially change as patient enrollment and
dosing continues and more patient data become available. Preliminary or interim data also remain subject to audit and verification procedures that may
result in the final data being materially different from the preliminary data we previously published. As a result, interim and preliminary data should be
viewed with caution until the final data are available. Adverse differences between preliminary or interim data and final data could significantly harm our
business, financial condition and results of operations.

50

 
Further, others, including regulatory agencies, may not accept or agree with our assumptions, estimates, calculations, conclusions or analyses or may
interpret or weigh the importance of data differently, which could impact the value of the particular program, the approvability or commercialization of the
particular product candidate or product and our company in general. Data disclosures must be carefully managed to conform to limitations on preapproval
promotion and laws related to clinical trial registration and posting of results. In addition, the information we choose to publicly disclose regarding a
particular study or clinical trial is based on what is typically extensive information, and you or others may not agree with what we determine is the material
or otherwise appropriate information to include in our disclosure, and any information we determine not to disclose may ultimately be deemed significant
with respect to future decisions, conclusions, views, activities or otherwise regarding a particular drug, product, product candidate or our business. If the
top-line data that we report differ from actual results, or if others, including regulatory authorities, disagree with the conclusions reached, our ability to
obtain approval for, and commercialize, our product candidates may be harmed, which could harm our business, financial condition and results of
operations.

Any disruption in our research and development facilities could adversely affect our business, financial condition and results of operations.

Our principal executive offices, which house our research and development programs, are in San Diego, California. Our facilities may be affected by
natural or man-made disasters. Earthquakes are of particular significance since our facilities are located in an earthquake-prone area. We are also vulnerable
to damage from other types of disasters, including power loss, attacks from extremist organizations, fires, floods and similar events. If our facilities are
affected by a natural or man-made disaster, we may be forced to curtail our operations and/or rely on third-parties to perform some or all of our research
and development activities. Although we believe we possess adequate insurance for damage to our property and the disruption of our business from
casualties, such insurance may not be sufficient to cover all of our potential losses and may not continue to be available to us on acceptable terms, or at all.
In the future, we may choose to expand our operations in either our existing facilities or in new facilities. If we expand our worldwide manufacturing
locations, there can be no assurance that this expansion will occur without implementation difficulties, or at all.

Effective February 6, 2021, the health officer of San Diego County, where our principal executive offices are located, issued an updated shelter-in-
place order, ordering, among other things, that all individuals living in the County of San Diego to remain in their homes or at their place of residence for
an indefinite period of time (subject to certain exceptions for essential businesses and to facilitate authorized necessary activities and reopened businesses)
to mitigate the impact of the COVID-19 pandemic. The order is scheduled to continue until further notice from the health officer of San Diego County. In
addition, in mid-March 2020, the Governor of California and the State Public Health Officer and Director of the California Department of Public Health
ordered all individuals living in the State of California to stay at their place of residence for an indefinite period of time (subject to certain exceptions to
facilitate authorized necessary activities, and subject to certain variances approved by the California Department of Public Health on a county-by-county
basis) to mitigate the impact of the COVID-19 pandemic. The executive order exempts certain individuals needed to maintain continuity of operations of
essential critical infrastructure sectors and additional sectors as the State Public Health Officer may designate as critical to protect health and well-being of
all Californians. In May 2020, the Governor of California issued an executive order that informed local health jurisdictions and industry sectors that they
may gradually reopen under new modifications and guidance provided by the state of California. In August 2020, the state of California released revised
criteria for loosening and tightening restrictions on certain activities on generally a county-by-county basis. Under the executive orders, San Diego County,
where our principal executive offices are located, continues to be subject to certain restrictions. These orders and others may be further modified, amended
and adopted depending upon the COVID-19 transmission rates in our county and state, as well as other factors. If the operations in our principal executive
offices or other facilities are deemed non-essential, we may not be able to operate for the duration of any shelter-in-place order, which could negatively
impact our business, operating results and financial condition.

Our business and operations would suffer in the event of system failures.

Despite the implementation of security measures, our internal computer systems and those of our CROs and other contractors and consultants are

vulnerable to damage from computer viruses, unauthorized access, cybersecurity attacks or hacking, natural disasters, terrorism, war and
telecommunication and electrical failures. In addition, as a result of the COVID-19 pandemic, we may face increased cybersecurity risks due to our
reliance, and the reliance of our CROs, contractors and consultants reliance, on internet technology and the number of our employees, and employees of
our CROs, contractors and consultants, who are working remotely, which may create additional opportunities for cybercriminals to exploit vulnerabilities.
While we have not experienced any such system failure, accident 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 drug development programs. For example, the loss of clinical trial data from completed or ongoing
or planned clinical trials could result in delays in our regulatory approval efforts and significantly increase our costs to recover or reproduce the data. To the
extent that any disruption or security breach was to result in a loss of or damage to our data or applications, or inappropriate disclosure of confidential or
proprietary information, we could incur material legal claims and liability, damage to our reputation, suffer loss or harm to our intellectual property rights
and the further research, development and commercial

51

 
 
efforts of our products and product candidates could be delayed. If we are held liable for a claim against which we are not insured or for damages
exceeding the limits of our insurance coverage, whether arising out of cybersecurity matters, or from some other matter, that claim could have a material
adverse effect on our results of operations.

Further, a cybersecurity attack, data breach or privacy violation that leads to disclosure or modification of, or prevents access to, patient information,

including personally identifiable information or protected health information, could harm our reputation, compel us to comply with federal and/or state
breach notification laws and foreign law equivalents, subject us to mandatory corrective action, require us to verify the correctness of database contents and
otherwise subject us to liability under laws and regulations that protect personal data, resulting in increased costs or loss of revenue. Our ability to
effectively manage and maintain our internal business information, and to ship products to customers and invoice them on a timely basis, depends
significantly on our enterprise resource planning system and other information systems. Portions of our information technology systems may experience
interruptions, delays or cessations of service or produce errors in connection with ongoing systems implementation work. Cybersecurity attacks in
particular are evolving and include, but are not limited to, threats, malicious software, ransom ware, attempts to gain unauthorized access to data and other
electronic security breaches that could lead to disruptions in systems, misappropriation of confidential or otherwise protected information and corruption of
data. If we are unable to prevent such cybersecurity attacks, data security breaches or privacy violations or implement satisfactory remedial measures, our
operations could be disrupted, and we may suffer loss of reputation, financial loss and other regulatory penalties because of lost or misappropriated
information, including sensitive patient data. In addition, these breaches and other inappropriate access can be difficult to detect, and any delay in
identifying them may lead to increased harm of the type described above.

The terms of our outstanding debt place restrictions on our operating and financial flexibility. If we raise additional capital through debt financing, the
terms of any new debt could further restrict our ability to operate our business.

On September 7, 2018, Scilex Pharma issued and sold senior secured notes due 2026 in an aggregate principal amount of $224,000,000 (the “Scilex
Notes”) for an aggregate purchase price of $140,000,000 (the “Scilex Offering”). In connection with the Scilex Offering, we also entered into an indenture,
as amended (the “Scilex Indenture”), governing the Scilex Notes with U.S. Bank National Association, a national banking association, as trustee (the
“Trustee”) and collateral agent, and Scilex Pharma. Pursuant to the Scilex Indenture, we agreed to irrevocably and unconditionally guarantee, on a senior
unsecured basis, the punctual performance and payment when due of all obligations of Scilex Pharma under the Scilex Indenture.

The Scilex Indenture governing the Scilex Notes contains customary events of default with respect to the Scilex Notes (including a failure to make

any payment of principal on the Scilex Notes when due and payable), and, upon certain events of default occurring and continuing, the Trustee by notice to
Scilex Pharma, or the holders of at least 25% in principal amount of the outstanding Scilex Notes by notice to Scilex Pharma and the Trustee, may (subject
to the provisions of the Scilex Indenture) declare 100% of the then-outstanding principal amount of the Scilex Notes to be due and payable. Upon such a
declaration of acceleration, such principal will be due and payable immediately. In the case of certain events, including bankruptcy, insolvency or
reorganization involving us or Scilex Pharma, the Scilex Notes will automatically become due and payable.

Pursuant to the Scilex Indenture, we and Scilex Pharma must also comply with certain covenants with respect to the commercialization of ZTlido, as

well as customary additional affirmative covenants, such as furnishing financial statements to the holders of the Scilex Notes, minimum cash requirements
and net sales reports, and negative covenants, including limitations on the following: the incurrence of debt, the payment of dividends by Scilex Pharma,
the repurchase of shares and, under certain conditions, making certain other restricted payments, the prepayment, redemption or repurchase of subordinated
debt, a merger, amalgamation or consolidation involving Scilex Pharma, engaging in certain transactions with affiliates; and the making of investments
other than those permitted by the Scilex Indenture.

For purposes of the Scilex Indenture, an event of default includes, among other things, (i) a failure to pay any amounts when due under the Scilex

Indenture, (ii) a breach or other failure to comply with the covenants (including financial, notice and reporting covenants) under the Scilex Indenture, (iii) a
failure to make any payment on, or other event triggering an acceleration under, other material indebtedness of us, and (iv) the occurrence of certain
insolvency or bankruptcy events (both voluntary and involuntary) involving us or certain of our subsidiaries.

If we raise any additional debt financing, the terms of such additional debt could further restrict our operating and financial flexibility.

to utilize existing net operating loss and tax credit carryforwards once the corporation experiences an ownership change as defined in Section 382. Under
the Tax Cut and Jobs Act of 2017 (the “TCJA”), as modified by the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”), U.S. federal
net operating losses incurred in 2018 and in future years may be carried forward indefinitely, but the deductibility of such U.S. federal net operating losses
is limited to 80 percent of taxable income beginning in 2021. It is uncertain if and to what extent various states will conform to the federal Tax Act or the
CARES Act. The CARES Act also reinstated the net operating loss carryback provisions whereby net operating losses incurred in calendar tax years 2018,
2019 and 2020 may be carried back to offset taxable income of the five tax years preceding the year of the loss. We have undergone an ownership change
for purposes of Section 382 in a prior year. For the year ended December 31, 2020, there was no impact of such limitations on our income tax provision.
Since our last ownership change we have had equity offerings or acquisitions that have equity as a component of the purchase price, which increases our
likelihood of experiencing a future ownership change under Section 382. Future equity offerings or acquisitions that have equity as a component of the
purchase price could constitute an ownership change under Section 382. If and when any other ownership change occurs, utilization of our net operating
loss and tax credit carryforwards may be limited by Section 382, which could potentially result in increased future tax liability to us.

Comprehensive tax reform legislation could adversely affect our business and financial condition.

Our effective income tax rate in the future could be adversely affected by a number of factors, including: changes in the mix of earnings in countries
with differing statutory tax rates, changes in the valuation of deferred tax assets and liabilities, changes in tax laws, and the outcome of income tax audits in
various jurisdictions. We regularly assess all of these matters to determine the adequacy of its tax provision, which is subject to significant discretion.

Our operations in China subject us to risks and uncertainties relating to the laws and regulations of China.

Certain of our operations are currently based in China. Under its current leadership, the government of China has been pursuing economic reform

policies, including by encouraging foreign trade and investment.  However, there is no assurance that the Chinese government will continue to pursue such
policies, that such policies will be successfully implemented, that such policies will not be significantly altered, or that such policies will be beneficial to
our operations in China.  China’s system of laws can be unpredictable, especially with respect to foreign investment and foreign trade. The promulgation of
new laws and regulations and changes to existing laws and regulations may adversely affect foreign investors and foreign entities with operations in China.
For example, the U.S. government has called for substantial changes to foreign trade policy with China and has recently raised, and has proposed to further
raise in the future, tariffs on several Chinese goods. China has retaliated with increased tariffs on U.S. goods, which we anticipate will increase our cost of
doing business in China. Any further changes in U.S. trade policy could trigger retaliatory actions by affected countries, including China, resulting in trade
wars and in increased costs for goods imported into the United States and our ability to sell goods and services in the affected countries. Such an outcome
may reduce customer demand for our products and services, especially if parties required to pay those tariffs increase their prices, or if trading partners
limit their trade with the United States. If these consequences are realized, this may materially and adversely affect our sales and our business.

Additionally, the biopharmaceutical industry in China is strictly regulated by the Chinese government.  Changes to Chinese regulations affecting

biopharmaceutical companies are unpredictable and may have a material adverse effect on our Chinese operations and on our business and financial
condition.

Our global operations are exposed to political and economic risks, commercial volatility and events beyond our control in the countries in which we
operate.

In addition to challenges specific to the United States, our operations, including but not limited to our operations outside of the United States, are

subject to a variety of political and economic risks, including risks arising from:

•

•

•

•

•

•

unexpected changes in international or domestic legal, regulatory or governmental requirements or regulations, including related to
intellectual property or the biopharmaceutical industry;

unexpected increases in taxes or tariffs;

trade protection measures or import or export licensing requirements;

the inability to obtain necessary foreign regulatory or pricing approvals of products in a timely manner;

fluctuations in foreign currency exchange rates;

difficulties in staffing and managing international operations;

53

 
 
 
 
 
 
 
•

•

•

•

•

•

less favorable intellectual property or other applicable laws;

the effects of the United Kingdom’s withdrawal from the European Union;

currency controls that restrict or prohibit the payment of funds or the repatriation of earnings to the United States;

increased costs of compliance with general business and tax regulations in these countries or regions;

divergent legal systems and regulatory frameworks; and

political and economic instability or corruption.

These risks and others may have a material adverse effect on our global operations and on our business and financial condition.

Uncertainty relating to the determination of LIBOR and the potential phasing out of LIBOR after 2021 may adversely affect our results of operations,
financial condition, liquidity and net worth.

We routinely engage in transactions involving financial instruments, such as the purchase of loans, securities or derivatives indexed to the London

Interbank Offered Rate (“LIBOR”) and the sale of LIBOR-indexed securities. In July 2017, the United Kingdom’s Financial Conduct Authority, which
regulates LIBOR, announced its intention to stop persuading or compelling the group of major banks that sustain LIBOR to submit rate quotations after
2021. As a result, it is uncertain whether LIBOR will continue to be quoted after 2021.

Efforts are underway to identify and transition to a set of alternative reference rates. The transition may lead to disruption, including yield volatility

on LIBOR-based securities. In addition, our use of an alternative reference rate may be subject to judicial challenges. If LIBOR ceases or changes in a
manner that causes regulators or market participants to question its viability, financial instruments indexed to LIBOR could experience disparate outcomes
based on their contractual terms, ability to amend those terms, market or product type, legal or regulatory jurisdiction, and a host of other factors. There can
be no assurance that legislative or regulatory actions will dictate what happens if LIBOR ceases or is no longer viable. In addition, while the Alternative
Reference Rates Committee was created to identify best practices for market participants regarding alternative interest rates, there can be no assurance that
broadly adopted industry practices will develop. Divergent industry or market participant actions could result after LIBOR is no longer available or viable.
It is uncertain what effect any divergent industry practices will have on the performance of financial instruments, including ones that we own or have
issued. Additionally, if an alternative method or index to LIBOR is selected, there can be no assurance that the alternative method or index will yield the
same or similar economic results over the lives of the financial instruments. These developments could have a material impact on our debt securities, which
could adversely affect our business, financial condition, liquidity, net worth or results of operations.

We have significantly restructured our business and currently have a two segment reporting structure. Our two industry segments, designated as
Sorrento Therapeutics and Scilex Pharma, have been in effect for a limited period of time and there are no assurances that we will be able to
successfully operate as a restructured business.

We have traditionally focused on the discovery and development of innovative therapies focused on oncology and the treatment of chronic cancer

pain as well as immunology and infectious diseases based on our platform technologies.

With our previous acquisition of a majority stake in Scilex Pharma, a developer of specialty pharmaceutical products for the treatment of chronic
pain, and the subsequent contribution of such stake to our majority-owned subsidiary, Scilex Holding, in connection with Scilex Holding’s acquisition of
Semnur Pharmaceuticals, Inc. (“Semnur”), a pharmaceutical company developing an injectable product for the treatment of lower back pain, Scilex
Holding will focus on non-opioid pain management.

Our strategy is based on a number of factors and assumptions, some of which are not within our control, such as the actions of third parties. There
can be no assurance that we will be able to successfully execute all or any elements of our strategy, or that our ability to successfully execute our strategy
will be unaffected by external factors. If we are unsuccessful in growing our business as planned, our financial performance could be adversely affected.

We are involved, and may become involved in the future, in disputes and other legal or regulatory proceedings that, if adversely decided or settled,
could materially and adversely affect our business, financial condition and results of operations.

We are, and may in the future become, party to litigation, regulatory proceedings or other disputes. For example, on April 3, 2019, we filed two legal

actions against, among others, Patrick Soon-Shiong and entities controlled by him, asserting claims for, among other things, fraud and breach of contract,
arising out of Dr. Soon-Shiong’s purchase of the drug Cynviloq™ from our

54

 
 
 
 
 
 
 
company in May 2015. The actions allege that Dr. Soon-Shiong and the other defendants, among other things, acquired the drug Cynviloq™ for the
purpose of halting its progression to the market. As an additional example, on May 26, 2020, Wasa Medical Holdings filed a putative federal securities
class action against us, our President, Chief Executive Officer and Chairman of the Board of Directors, Henry Ji, Ph.D., and our SVP of Regulatory Affairs,
Mark R. Brunswick, Ph.D., alleging that we, Dr. Ji and Dr. Brunswick made materially false and/or misleading statements to the investing public regarding
STI-1499 and its ability to inhibit the SARS-CoV-2 virus infection. A second putative federal securities class action was filed in the U.S. District Court for
the Southern District of California against the same defendants alleging the same claims and seeking the same relief. In general, claims made by or against
us in disputes and other legal or regulatory proceedings can be expensive and time consuming to bring or defend against, requiring us to expend significant
resources and divert the efforts and attention of our management and other personnel from our business operations. While we intend to pursue any claims
made by us, or defend against any claims brought against us, vigorously, we cannot predict the outcomes of such claims. Any failure to prevail in any
claims made by us or any adverse determination against us in these proceedings, or even the allegations contained in the claims, regardless of whether they
are ultimately found to be without merit, may also result in settlements, injunctions or damages that could have a material adverse effect on our business,
financial condition and results of operations.

Risks Related to Acquisitions

We have acquired, and plan to continue to acquire, assets, businesses and technologies and may fail to realize the anticipated benefits of the
acquisitions, and acquisitions can be costly and dilutive.

We have and plan to continue to expand our assets, business and intellectual property portfolio through the acquisition of new assets, businesses and

technologies. 

For example, in November 2016, we acquired a majority of the outstanding capital stock of Scilex Pharma, which was contributed to our majority-
owned subsidiary Scilex Holding in connection with the corporate reorganization of Scilex Holding and acquisition of Semnur by Scilex Holding in March
2019. These assets, together, constitute our Scilex segment. We also acquired Virttu Biologics Limited in 2017 and Sofusa® assets, a revolutionary drug
delivery technology, in July 2018. We also acquired SmartPharm Therapeutics, Inc. in September 2020, and are in the process of integrating this company
and its technology with ours. In addition, in October 2020, we announced our potential acquisition of ACEA Therapeutics, Inc.

The success of any acquisition depends on, among other things, our ability to combine our business with the acquired business in a manner that does

not materially disrupt existing relationships and that allows us to achieve development and operational synergies. If we are unable to achieve these
objectives, the anticipated benefits of the acquisition may not be realized fully or at all or may take longer to realize than expected. In particular, the
acquisition may not be accretive to our stock value or development pipeline in the near or long term.

It is possible that the integration process could result in the loss of key employees; the disruption of our ongoing business or the ongoing business of

the acquired companies; or inconsistencies in standards, controls, procedures or policies that could adversely affect our ability to maintain relationships
with third parties and employees or to achieve the anticipated benefits of the acquisition. Integration efforts between us and the acquired company will also
divert management’s attention from our core business and other opportunities that could have been beneficial to our stockholders. An inability to realize the
full extent of, or any of, the anticipated benefits of the acquisition, as well as any delays encountered in the integration process, could have an adverse
effect on our business and results of operations, which may affect the value of the shares of our common stock after the completion of the acquisition. If we
are unable to achieve these objectives, the anticipated benefits of the acquisition may not be realized fully or at all or may take longer to realize than
expected. In particular, the acquisition may not be accretive to our stock value or development pipeline in the near or long term.

We expect to incur additional costs integrating the operations of any companies we acquire, higher development and regulatory costs, and personnel,
which cannot be estimated accurately at this time. If the total costs of the integration of our companies and advancement of acquired product candidates and
technologies exceed the anticipated benefits of the acquisition, our financial results could be adversely affected.

In addition, we may issue shares of our common stock or other equity-linked securities in connection with future acquisitions of businesses and

technologies. Any such issuances of shares of our common stock could result in material dilution to our existing stockholders.

55

 
We may be required to make milestone payments to the former stockholders of Semnur in connection with our development and commercialization of
SEMDEXATM, which could adversely affect the overall profitability of SEMDEXATM, if approved.

Under the terms of the Agreement and Plan of Merger Scilex Holding entered into with Semnur, Sigma Merger Sub, Inc., the prior wholly-owned

subsidiary of Scilex Holding, Fortis Advisors LLC, solely as representative of the holders of Semnur equity (the “Semnur Equityholders”), and us, for
limited purposes, Scilex Holding is obligated to pay the Semnur Equityholders up to an aggregate of $280.0 million in contingent cash consideration based
on the achievement of certain milestones. A $40.0 million payment will be due upon obtaining the first approval of an NDA by the FDA of any Semnur
product, which includes SEMDEXATM. Additional payments of up to $240 million will be due upon the achievement of certain cumulative net sales of
Semnur products

These milestone obligations could impose substantial additional costs on our Scilex operating segment, divert resources from other aspects of its

business, and adversely affect the overall profitability of SEMDEXATM, if approved. We may need to obtain additional financing to satisfy these milestone
payments, and cannot be sure that any additional funding, if needed, will be available on terms favorable to us, or at all.

If we acquire companies or technologies in the future, they could prove difficult to integrate, disrupt our business, dilute stockholder value, and
adversely affect our operating results and the value of our common stock.

As part of our business strategy, we may continue to acquire, enter into joint ventures with, or make investments in complementary or synergistic

companies, services, and technologies in the future. Acquisitions and investments involve numerous risks, including:

•

•

•

•

•

•

difficulties in identifying and acquiring products, technologies, proprietary rights or businesses that will help our business;

difficulties in integrating operations, technologies, services, and personnel;

diversion of financial and managerial resources from existing operations;

the risk of entering new development activities and markets in which we have little to no experience;

risks related to the assumption of known and unknown liabilities; and

risks related to our ability to raise sufficient capital to fund additional operating activities.

As a result, if we fail to properly evaluate acquisitions or investments, we may not achieve the anticipated benefits of any such acquisitions, we may

incur costs in excess of what we anticipate, and management resources and attention may be diverted from other necessary or valuable activities.

Any acquisitions we make could disrupt our business and seriously harm our financial condition.

We have in the past made (and may, from time to time, consider) acquisitions of complementary companies, products or technologies. Acquisitions

involve numerous risks, including difficulties in the assimilation of the acquired businesses, the diversion of our management’s attention from other
business concerns and potential adverse effects on existing business relationships. In addition, any acquisitions could involve the incurrence of substantial
additional indebtedness. We cannot assure you that we will be able to successfully integrate any acquisitions that we pursue or that such acquisitions will
perform as planned or prove to be beneficial to our operations and cash flow. Any such failure could seriously harm our business, financial condition and
results of operations.

Risks Related to Our Intellectual Property

Our ability to protect our intellectual property rights will be critically important to the success of our business, and we may not be able to protect these
rights in the U.S. or abroad.

Our success, competitive position and future revenues will depend in part on our ability to obtain and maintain patent protection for our product
candidates, methods, processes and other technologies, to prevent third parties from infringing on our proprietary rights, exclude others from using our
technology and to operate without infringing upon the proprietary rights of third parties. We will be able to protect our proprietary rights from unauthorized
use by third parties only to the extent that our proprietary rights are covered by valid and enforceable patents or are effectively maintained as trade secrets.
We attempt to protect our proprietary position by maintaining trade secrets and by filing U.S. and foreign patent applications related to our proprietary
technology, inventions and improvements that are important to the development of our business. The first of the antibody family patent applications was
issued in 2014, and we continue to file additional patent applications for our product candidates and technology.

56

 
 
 
 
 
 
 
We have commenced generating a patent portfolio to protect each product candidate in our pipeline. However, the patent position of

biopharmaceutical companies involves complex legal and factual questions, and therefore we cannot predict with certainty whether any patent applications
that we have filed or that we may file in the future will be approved, will cover our products or product candidates or that any resulting patents will be
enforced. In addition, third parties may challenge, seek to invalidate, limit the scope of or circumvent any of our patents, once they are issued. Thus, any
patents that we own or license from third parties or joint venture or development partners may not provide any protection against competitors. Any patent
applications that we have filed or that we may file in the future, or those we may license from third parties or joint venture or development partners, may
not result in patents being issued. Moreover, disputes between our licensing or joint development partners and us may arise over license scope, or
ownership, assignment, inventorship and/or rights to use or commercialize patent or other proprietary rights, which may adversely impact our ability to
obtain and protect our proprietary technology and products. Also, patent rights may not provide us with adequate proprietary protection or competitive
advantages against competitors with similar technologies or products.

In addition, the laws of certain foreign countries do not protect our intellectual property rights to the same extent as do the laws of the U.S. If we fail

to apply for intellectual property protection or if we cannot adequately protect our intellectual property rights in these foreign countries, our competitors
may be able to compete more effectively against us, which could adversely affect our competitive position, as well as our business, financial condition and
results of operations.

Periodic maintenance fees, renewal fees, annuity fees and various other governmental fees on patents and/or applications will be due to the PTO and
various foreign patent offices at various points over the lifetime of our patents and/or applications. We have systems in place to remind us to pay these fees,
and we rely on our outside counsel or service providers to pay these fees when due. Additionally, the PTO and various foreign patent offices require
compliance with a number of procedural, documentary, fee payment and other similar provisions during the patent application process. We employ
reputable law firms and other professionals to help us comply, and in many cases, an inadvertent lapse can be cured by payment of a late fee or by other
means in accordance with rules applicable to the particular jurisdiction. However, there are situations in which noncompliance 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. If such an event were to occur, it
could have a material adverse effect on our business. In addition, we are responsible for the payment of patent fees for patent rights that we have licensed
from other parties. If any licensor of these patents does not itself elect to make these payments, and we fail to do so, we may be liable to the licensor for any
costs and consequences of any resulting loss of patent rights.

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 our patents could limit our ability to assert our 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. Any of these
occurrences could adversely affect our competitive business position, business prospects and financial condition. 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 have a material adverse effect on 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.

57

 
Our long-term success depends on intellectual property protection; if our intellectual property rights are invalidated or circumvented, our business will
be adversely affected.

Our long-term success depends on our ability to continually discover, develop and commercialize innovative new pharmaceutical products. Without

strong intellectual property protection, we would be unable to generate the returns necessary to support the enormous investments in research and
development and capital as well as other expenditures required to bring new drugs to the market and for commercialization.

Intellectual property protection varies throughout the world and is subject to change over time. In the U.S., for small molecule drug products, such
as ZTlido (which is held by our subsidiary, Scilex Holding), the Hatch-Waxman Act provides generic companies powerful incentives to seek to invalidate
our pharmaceutical patents. As a result, we expect that our U.S. patents on major pharmaceutical products will be routinely challenged, and there can be no
assurance that our patents will be upheld. We face generic manufacturer challenges to our patents outside the U.S. as well. In addition, competitors or other
third parties may claim that our activities infringe patents or other intellectual property rights held by them. If successful, such claims could result in our
being unable to market a product in a particular territory or being required to pay damages for past infringement or royalties on future sales.

If any of our trade secrets, know-how or other proprietary information is disclosed, the value of our trade secrets, know-how and other proprietary
rights would be significantly impaired and our business and competitive position would suffer.

Our success also depends upon the skills, knowledge and experience of our scientific and technical personnel and our consultants and advisors, as

well as our licensors. To help protect our proprietary know-how and our inventions for which patents may be unobtainable or difficult to obtain, or prior to
seeking patent protection, we rely on trade secret protection and confidentiality agreements. Unlike some of our competitors, in addition to certain
manufacturing processes, we maintain our proprietary libraries for ourselves as trade secrets. To this end, we require all our employees, consultants,
advisors and contractors to enter into agreements which prohibit the disclosure of confidential information and, where applicable, require disclosure and
assignment to us of the ideas, developments, discoveries and inventions important to our business. These agreements may not provide adequate protection
for our trade secrets, know-how or other proprietary information in the event of any unauthorized use or disclosure or the lawful development by others of
such information. If any of our trade secrets, know-how or other proprietary information is disclosed, the value of our trade secrets, know-how and other
proprietary rights would be significantly impaired and our business and competitive position would suffer. Moreover, our third-party licensing partners may
retain rights in some of our proprietary or joint trade secrets, know-how, patented inventions or other proprietary information, including rights to sublicense
and rights of publication, which may adversely impact our ability to obtain patents and protect trade secrets, know-how or other proprietary information. In
addition, the U.S. government may retain rights in some of our patents or other proprietary information.

Third party competitors may seek to challenge the validity of our patents, thereby rendering them unenforceable or we may seek to challenge third

party competitor patents if such third parties seek to interpret or enforce a claim scope going well beyond the actual enabled invention.

In addition, many of the formulations used and processes developed by us in manufacturing any of our collaborators’ products are subject to trade

secret protection, patents or other intellectual property protections owned or licensed by such collaborator. While we make significant efforts to protect our
collaborators’ proprietary and confidential information, including requiring our employees to enter into agreements protecting such information, if any of
our employees breaches the non-disclosure provisions in such agreements, or if our collaborators make claims that their proprietary information has been
disclosed, our reputation may suffer damage and we may become subject to legal proceedings that could require us to incur significant expenses and divert
our management’s time, attention and resources.

Claims that we infringe upon the rights of third parties may give rise to costly and lengthy litigation, and we could be prevented from selling products,
forced to pay damages, and defend against litigation.

Third parties may assert patent or other intellectual property infringement claims against us or our strategic partners or licensees with respect to our

technologies and product candidates or potential product candidates. If our products, methods, processes and other technologies infringe upon the
proprietary rights of other parties, we could incur substantial costs and we may have to:

•

•

•

obtain licenses, which may not be available on commercially reasonable terms, if at all, and may be non-exclusive, thereby giving our
competitors access to the same intellectual property licensed to us;

redesign our products or processes to avoid infringement;

stop using the subject matter validly claimed in the patents held by others;

58

 
 
 
 
•

•

pay damages; and

defend litigation or administrative proceedings which may be costly whether we win or lose, and which could result in a substantial diversion
of our valuable management resources.

Even if we were to prevail, any litigation could be costly and time-consuming and would divert the attention of our management and key personnel

from our business operations. Furthermore, as a result of a patent infringement suit brought against us or our strategic partners or licensees, we or our
strategic partners or licensees may be forced to stop or delay developing, manufacturing or selling technologies, product candidates or potential products
that are claimed to infringe a third party’s intellectual property unless that party grants us or our strategic partners’ or licensees’ rights to use its intellectual
property. Ultimately, we may be unable to develop some of our technologies or potential products or may have to discontinue development of a product
candidate or cease some of our business operations as a result of patent infringement claims, which could severely harm our business.

In addition, our collaborators’ products may be subject to claims of intellectual property infringement and such claims could materially affect our

CMO business if their products cease to be manufactured and they have to discontinue the use of the infringing technology which we may provide. Any of
the foregoing could affect our ability to compete or could have a material adverse effect on our business, financial condition and results of operations.

Our position as a relatively small company may cause us to be at a significant disadvantage in defending our intellectual property rights and in
defending against infringement claims by third parties.

Litigation relating to the ownership and use of intellectual property is expensive, and our position as a relatively small company in an industry

dominated by very large companies may cause us to be at a significant disadvantage in defending our intellectual property rights and in defending against
claims that our technology infringes or misappropriates third party intellectual property rights. However, we may seek to use various post-grant
administrative proceedings, including new procedures created under the America Invents Act, to invalidate potentially overly-broad third party rights. Even
if we can defend our position, the cost of doing so may adversely affect our ability to grow, generate revenue or become profitable. In the course of the
ongoing litigation or any future additional litigation to which we may be subject, we may not be able to protect our intellectual property at a reasonable
cost, or at all. The outcome of litigation is always uncertain, and in some cases could include judgments against us that require us to pay damages, enjoin us
from certain activities or otherwise affect our legal, contractual or intellectual property rights, which could have a significant adverse effect on our business.

Third-party claims of intellectual property infringement may prevent or delay our drug discovery and development efforts.

Our commercial success depends in part on our avoiding infringement of the patents and proprietary rights of third parties.

There is a substantial amount of litigation involving patent and other intellectual property rights in the biotechnology and pharmaceutical industries,
including PTO administrative proceedings, such as inter partes reviews, and reexamination proceedings before the PTO or oppositions and revocations and
other comparable proceedings in foreign jurisdictions. Numerous U.S. and foreign issued patents and pending patent applications, which are owned by
third parties, exist in the fields in which we are developing product candidates. As the biotechnology and pharmaceutical industries expand and more
patents are issued, the risk increases that our product candidates may give rise to claims of infringement of the patent rights of others.

Despite safe harbor provisions, third parties may assert that we are employing their proprietary technology without authorization. There may be

third-party patents, of which we are currently unaware, with claims to materials, formulations, methods of doing research or library screening, 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 published applications which may later result in issued patents that our product candidates may infringe. In
addition, third parties may obtain patents in the future and claim that use of our technologies infringes upon these patents. If any third-party patents were
held by a court of competent jurisdiction to cover the manufacturing process of any of our product candidates, any molecules formed during the
manufacturing process or any final product itself, the holders of any such patents may be able to block our ability to commercialize such product candidate
unless we obtain a license under the applicable patents, or until such patents expire or they are finally determined to be held invalid or unenforceable.
Similarly, if any third-party patent were held by a court of competent jurisdiction to cover aspects of our formulations, processes for manufacture or
methods of use, including combination therapy or patient selection methods, the holders of any such patent may be able to block our ability to develop and
commercialize the applicable product candidate unless we obtain a license, limit our uses, or until such patent expires or is finally determined to be held
invalid or unenforceable. In either case, such a license may not be available on commercially reasonable terms or at all.

Parties making claims against us may obtain injunctive or other equitable relief, which could effectively block our ability to further develop and

commercialize one or more of our product candidates. Defense of these claims, regardless of their merit, would

59

 
 
 
involve substantial litigation expense and would be a substantial diversion of employee resources from our business. In the event of a successful claim of
infringement against us, we may have to pay substantial damages, including treble damages and attorneys’ fees for willful infringement, obtain one or more
licenses from third parties, cease marketing our products or developing our product candidates, limit our uses, pay royalties or redesign our infringing
product candidates, which may be impossible or require substantial time and monetary expenditure. We cannot predict whether any such license would be
available at all or whether it would be available on commercially reasonable terms. Furthermore, even in the absence of litigation, we may need to obtain
licenses from third parties to advance our research or allow commercialization of our product candidates. We may fail to obtain any of these licenses at a
reasonable cost or on reasonable terms, if at all. In that event, we would be unable to further develop and commercialize one or more of our product
candidates, which could harm our business significantly.

We may not be able to protect our intellectual property rights throughout the world.

Filing, prosecuting and defending patents on all of our product candidates throughout the world would be prohibitively expensive. Competitors may

use our technologies in jurisdictions where we have not obtained patent protection to develop their own products and further, may export otherwise
infringing products to territories where we have patent protection, but enforcement is not as strong as that in the U.S. These products may compete with our
products in jurisdictions where we do not have any issued patents and our patent claims or other intellectual property rights may not be effective or
sufficient to prevent them from so competing.

Many companies have encountered significant problems in protecting and defending intellectual property rights in foreign jurisdictions. The legal
systems of certain countries, particularly certain developing countries, do not favor the enforcement of patents and other intellectual property protection,
particularly those relating to biopharmaceuticals, which could make it difficult for us to stop the infringement of our patents or marketing of competing
products in violation of our proprietary rights generally. Proceedings to enforce our patent rights in foreign jurisdictions could result in substantial cost and
divert our efforts and attention from other aspects of our business.

Confidentiality agreements with employees and others may not adequately prevent disclosure of our trade secrets and other proprietary information
and may not adequately protect our intellectual property, which could limit our ability to compete.

Because we operate in the highly technical field of research and development of biologics and small molecule drugs, we rely in part on trade secret

protection in order to protect our proprietary trade secrets and unpatented know-how. However, trade secrets are difficult to protect, and we cannot be
certain that others will not develop the same or similar technologies on their own. We have taken steps, including entering into confidentiality agreements
with our employees, consultants, outside scientific collaborators, sponsored researchers and other advisors, to protect our trade secrets and unpatented
know-how. These agreements generally require that the other party keep confidential and not disclose to third parties all confidential information developed
by the party or made known to the party by us during the party’s relationship with us. We also typically obtain agreements from these parties which provide
that inventions conceived by the party in the course of rendering services to us will be our exclusive property. However, these agreements may not be
honored and may not effectively assign intellectual property rights to us. Enforcing a claim that a party illegally obtained and is using our trade secrets or
know-how is difficult, expensive and time consuming, and the outcome is unpredictable. In addition, courts outside the U.S. may be less willing to protect
trade secrets or know-how. The failure to obtain or maintain trade secret protection could adversely affect our competitive position.

If we breach any of the agreements under which we license commercialization rights to our product candidates from third parties, we could lose license
rights that are important to our business.

We license the use, development and commercialization rights for all of our product candidates and may enter into similar licenses in the future.

Under each of our existing license agreements we are subject to commercialization and development, diligence obligations, milestone payment obligations,
royalty payments and other obligations. If we fail to comply with any of these obligations or otherwise breach our license agreements, our licensing
partners may have the right to terminate the license in whole or in part.

For example, certain of our joint development and/or licensing agreements set forth diligence milestones including timelines in which certain
clinical trials should be initiated. Due to the uncertainty of drug development and clinical trials as set forth above, we may not be able to meet these
diligence milestones, which could result in loss of exclusivity or loss of our rights to develop certain products or services pursuant to those agreements.

Generally, the loss of any one of our current licenses or other licenses in the future could materially harm our business, prospects, financial condition

and results of operations.

60

 
Intellectual property rights do not necessarily address all potential threats to our competitive advantage.

The degree of future protection afforded by our intellectual property rights is uncertain because intellectual property rights have limitations, and may

not adequately protect our business, or permit us to maintain our competitive advantage. The following examples are illustrative:

•

•

•

•

•

•

•

•

•

Others may be able to make compounds that are similar to our product candidates but that are not covered by the claims of the patents that we
own or have exclusively licensed;

We or our licensors or strategic partners might not have been the first to make the inventions covered by the issued patent or pending patent
application that we own or have exclusively licensed;

We or our licensors or strategic partners might not have been the first to file patent applications covering certain of our inventions;

Others may independently develop similar or alternative technologies or duplicate any of our technologies without infringing our intellectual
property rights;

Our pending patent applications may not lead to issued patents;

Issued patents that we own or have exclusively licensed may not provide us with any competitive advantages, or may be held invalid or
unenforceable, as a result of legal challenges by our competitors;

Our competitors might conduct research and development activities in countries where we do not have patent rights and then use the
information learned from such activities to develop competitive products for sale in our major commercial markets;

We may not develop additional proprietary technologies that are patentable; and

The patents of others may have an adverse effect on our business.

Should any of these events occur, they could significantly harm our business, results of operations and prospects.

From time to time we may need to license patents, intellectual property and proprietary technologies from third parties, which may be difficult or
expensive to obtain.

We may need to obtain licenses to patents and other proprietary rights held by third parties to successfully develop, manufacture and market our

drug products. As an example, it may be necessary to use a third party’s proprietary technology to reformulate one of our drug products in order to improve
upon the capabilities of the drug product. If we are unable to timely obtain these licenses on reasonable terms, our ability to commercially exploit our drug
products may be inhibited or prevented.

We remain responsible for payments of all milestone and license fees to Samyang Biopharmaceuticals Corporation pursuant to our agreement with
NantPharma.

As a result of our acquisition of IgDraSol, Inc. in September 2013, we became a party to an Exclusive Distribution Agreement, as amended, with

Samyang Biopharmaceuticals Corporation (“Samyang”) in connection with our development of Cynviloq™ which contained various milestone and license
fees to be paid to Samyang. On May 14, 2015, we sold all our equity interests in IgDrasol, Inc. to NantPharma, LLC (“NantPharma”). As part of the sale,
we agreed with NantPharma to be responsible for and pay all milestone and license fees required to be paid to Samyang under the Exclusive Distribution
Agreement following notification from NantPharma when such milestone and license fees become due and payable. If such milestone or licenses fees
become due and payable, the payment thereof could materially harm our business and financial condition.

Risks Related to Ownership of Our Common Stock

The market price of our common stock may fluctuate significantly, and investors in our common stock may lose all or a part of their investment.

The market prices for securities of biotechnology and pharmaceutical companies have historically been highly volatile, and the market has from

time to time experienced significant price and volume fluctuations that are unrelated to the operating performance of particular companies. For example,
from January 2, 2020 to December 31, 2020, our closing stock price ranged from $1.57 to $18.82 per share. The market price of our common stock may
fluctuate significantly in response to numerous factors, some of which are beyond our control, such as:

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

actual or anticipated adverse results or delays in our clinical trials;

our failure to commercialize our product candidates, if approved;

unanticipated serious safety concerns related to the use of any of our product candidates;

adverse regulatory decisions;

changes in laws or regulations applicable to our product candidates, including but not limited to clinical trial requirements for approvals;

legal disputes or other developments relating to proprietary rights, including patents, litigation matters and our ability to obtain patent
protection for our product candidates, government investigations and the results of any proceedings or lawsuits, including, but not limited to,
patent or stockholder litigation;

our decision to initiate a clinical trial, not initiate a clinical trial or to terminate an existing clinical trial;

our dependence on third parties, including CROs;

announcements of the introduction of new products by our competitors;

market conditions in the pharmaceutical and biotechnology sectors;

announcements concerning product development results or intellectual property rights of others;

future issuances of common stock or other securities;

the addition or departure of key personnel;

failure to meet or exceed any financial guidance or expectations regarding development milestones that we may provide to the public;

actual or anticipated variations in quarterly operating results;

our failure to meet or exceed the estimates and projections of the investment community;

overall performance of the equity markets and other factors that may be unrelated to our operating performance or the operating performance
of our competitors, including changes in market valuations of similar companies;

conditions or trends in the biotechnology and biopharmaceutical industries;

introduction of new products offered by us or our competitors;

announcements of significant acquisitions, strategic partnerships, joint ventures or capital commitments by us or our competitors;

issuances of debt or equity securities;

sales of our common stock by us or our stockholders in the future;

trading volume of our common stock;

ineffectiveness of our internal controls;

publication of research reports about us or our industry or positive or negative recommendations or withdrawal of research coverage by
securities analysts;

failure to effectively integrate the acquired companies’ operations;

general political and economic conditions;

effects of natural or man-made catastrophic events;

effects of public health crises, pandemics and epidemics, such as the COVID-19 pandemic; and

other events or factors, many of which are beyond our control.

Further, the equity markets in general have recently experienced extreme price and volume fluctuations. Continued market fluctuations could result
in extreme volatility in the price of our common stock, which could cause a decline in the value of our common stock. Price volatility of our common stock
might worsen if the trading volume of our common stock is low. The realization of any of the above risks or any of a broad range of other risks, including
those described in these “Risk Factors,” could have a dramatic and material adverse impact on the market price of our common stock.

We have not paid cash dividends in the past and do not expect to pay cash dividends in the foreseeable future. Any return on investment may be limited
to the value of our common stock.

We have never paid cash dividends on our common stock and do not anticipate paying cash dividends on our common stock in the foreseeable
future. The payment of dividends on our capital stock will depend on our earnings, financial condition and other business and economic factors affecting us
at such time as the board of directors may consider relevant. If we do not pay dividends, our common stock may be less valuable because a return on your
investment will only occur if the common stock price appreciates.

Our strategic investments may result in losses.

We periodically make strategic investments in various public and private companies with businesses or technologies that may complement our

business. The market values of these strategic investments may fluctuate due to market conditions and other conditions over which we have no control.
Other-than-temporary declines in the market price and valuations of the securities that we hold in other companies would require us to record losses related
to our investment. This could result in future charges to our earnings. It is uncertain whether or not we will realize any long-term benefits associated with
these strategic investments.

A sale of a substantial number of shares of the common stock may cause the price of our common stock to decline.

If our stockholders sell, or the market perceives that our stockholders intend to sell for various reasons, substantial amounts of our common stock in
the public market, including shares issued in connection with the exercise of outstanding options or warrants, the market price of our common stock could
fall. Sales of a substantial number of shares of our common stock may make it more difficult for us to sell equity or equity-related securities in the future at
a time and price that we deem reasonable or appropriate. We may become involved in securities class action litigation that could divert management’s
attention and harm our business.

The stock markets have from time to time experienced significant price and volume fluctuations that have affected the market prices for the common

stock of biotechnology and biopharmaceutical companies. These broad market fluctuations may cause the market price of our common stock to decline. In
the past, securities class action litigation has often been brought against a company following a decline in the market price of our securities. This risk is
especially relevant for us because biotechnology and biopharmaceutical companies have experienced significant stock price volatility in recent years. We
may become involved in this type of litigation in the future. Litigation often is expensive and diverts management’s attention and resources, which could
adversely affect our business.

Our quarterly operating results may fluctuate significantly.

We expect our operating results to be subject to quarterly fluctuations. Our net loss and other operating results will be affected by numerous factors,

including:

•

•

•

•

•

variations in the level of expenses related to our development programs;

the addition or termination of clinical trials;

any intellectual property infringement lawsuit in which we may become involved;

regulatory developments affecting our product candidates; and

our execution of any collaborative, licensing or similar arrangements, and the timing of payments we may make or receive under these
arrangements.

63

 
 
 
 
 
 
 
 
 
If our quarterly operating results fall below the expectations of investors or securities analysts, the price of our common stock could decline
substantially. Furthermore, any quarterly fluctuations in our operating results may, in turn, cause the price of our common stock to fluctuate substantially.

Existing stockholders’ interest in us may be diluted by additional issuances of equity securities and raising funds through acquisitions, lending and
licensing arrangements may restrict our operations or require us to relinquish proprietary rights.

We may issue additional equity securities to fund future expansion and pursuant to equity incentive or employee benefit plans. We may also issue
additional equity for other purposes. These securities may have the same rights as our common stock or, alternatively, may have dividend, liquidation or
other preferences to our common stock. The issuance of additional equity securities will dilute the holdings of existing stockholders and may reduce the
share price of our common stock.

If we raise additional funds through collaboration, licensing or other similar arrangements, it may be necessary to relinquish potentially valuable

rights to our product candidates, potential products or proprietary technologies, or grant licenses on terms that may not be favorable to us. If adequate funds
are not available, our ability to achieve profitability or to respond to competitive pressures would be significantly limited and we may be required to delay,
significantly curtail or eliminate the development of our product candidates.

Our investors could experience substantial dilution of their investments as a result of subsequent exercises of our outstanding options, including the
CEO Performance Award, or the grant of future equity awards by us.

As of December 31, 2020, 82.0 million shares of our common stock were reserved for issuance under our equity incentive plans, of which 18.8

million shares of our common stock were subject to options outstanding at such date at a weighted-average exercise price of $4.97 per share,  12.1 million
shares of our common stock were reserved for issuance pursuant to our 2019 Stock Incentive Plan and 7.5 million shares of our common stock were
reserved for issuance pursuant to our 2020 Employee Stock Purchase Plan. Over the past several months, we have experienced higher rates of stock option
exercises compared to many earlier periods, and this trend may continue. In addition, 24,935,882 shares of our common stock are subject to the 10-year
CEO performance award granted to Dr. Ji that is tied solely to achieving market capitalization milestones and has an exercise price of $17.30 per share. To
the extent outstanding options are exercised, our existing stockholders may incur dilution.

We rely on equity awards to motivate current employees and to attract new employees. The grant of future equity awards by us to our employees

and other service providers may further dilute our stockholders.

Our directors and executive officers own a significant percentage of our capital stock, and they may make decisions that you do not consider to be in
your best interests or those of our other stockholders.

As of December 31, 2020, our directors and executive officers beneficially owned, in the aggregate, approximately 3.2% of our outstanding voting

securities. As a result, if some or all of them acted together, they would have the ability to exert significant influence over the election of our board of
directors and the outcome of issues requiring approval by our stockholders. This concentration of ownership may also have the effect of delaying or
preventing a change in control of our company that may be favored by other stockholders. This could prevent transactions in which stockholders might
otherwise recover a premium for their shares over current market prices.

Our certificate of incorporation, as amended, and bylaws provide for indemnification of officers and directors at our expense and limits their liability,
which may result in a major cost to us and hurt the interests of our stockholders because corporate resources may be expended for the benefit of our
officers and/or directors.

Our certificate of incorporation, as amended, bylaws and applicable Delaware law provide for the indemnification of our directors, officers,
employees, and agents, under certain circumstances, against attorney’s fees and other expenses incurred by them in any litigation to which they become a
party arising from their association with or activities on our behalf. We will also bear the expenses of such litigation for any of our directors, officers,
employees, or agents, upon such person’s promise to repay us, therefore if it is ultimately determined that any such person shall not have been entitled to
indemnification. This indemnification policy could result in substantial expenditures by us, which we will be unable to recover.

64

 
Our corporate documents and Delaware law contain provisions that could discourage, delay or prevent a change in control of our company, prevent
attempts to replace or remove current management and reduce the market price of our common stock.

Provisions in our certificate of incorporation, as amended, and bylaws may discourage, delay or prevent a merger or acquisition involving us that

our stockholders may consider favorable. For example, our certificate of incorporation, as amended, authorizes our board of directors to issue up to
100,000,000 shares of “blank check” preferred stock. As a result, without further stockholder approval, the board of directors has the authority to attach
special rights, including voting and dividend rights, to this preferred stock. With these rights, preferred stockholders could make it more difficult for a third
party to acquire us.

We are also subject to the anti-takeover provisions of the General Corporation Law of the State of Delaware. Under these provisions, if anyone
becomes an “interested stockholder,” we may not enter into a “business combination” with that person for three years without special approval, which
could discourage a third party from making a takeover offer and could delay or prevent a change in control of us. An “interested stockholder” means,
generally, someone owning 15% or more of our outstanding voting stock or an affiliate of ours that owned 15% or more of our outstanding voting stock
within the past three years, subject to certain exceptions as described in the General Corporation Law of the State of Delaware.

Our Amended and Restated Bylaws provide that the Court of Chancery in the State of Delaware is the sole and exclusive forum for substantially all
disputes between us and our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our
directors, officers or employees.

Our Amended and Restated Bylaws (our “Bylaws”), provide that, unless our Board of Directors consents to an alternative forum, the Court of

Chancery in the State of Delaware will be the sole and exclusive forum for: (i) any derivative action or proceeding brought by or on our behalf; (ii) any
direct action asserting a claim against us or any of our directors or officers pursuant to any of the provisions of the General Corporation Law of the State of
Delaware, our Restated Certificate of Incorporation or our Bylaws; (iii) any action asserting a claim of breach of fiduciary duties owed by any of our
directors, officers or other employees to our stockholders; or (iv) any action asserting a violation of Delaware decisional law relating to our internal affairs.
This provision does not apply to (a) actions in which the Court of Chancery in the State of Delaware concludes that an indispensable party is not subject to
the jurisdiction of Delaware courts, or (b) actions in which a federal court has assumed exclusive jurisdiction to a proceeding. This choice of forum
provision is not intended to apply to any actions brought under the Securities Act of 1933, as amended, or the Securities Act, or the Securities Exchange
Act of 1934, as amended, or the Exchange Act. Section 27 of the Exchange Act creates exclusive federal jurisdiction over all suits brought to enforce any
duty or liability created by the Exchange Act or the rules and regulations thereunder. As a result, the exclusive forum provision will not apply to suits
brought to enforce any duty or liability created by the Exchange Act or any other claim for which the federal courts have exclusive jurisdiction. However,
our Bylaws do not relieve us of our duties to comply with federal securities laws and the rules and regulations thereunder, and our stockholders will not be
deemed to have waived our compliance with these laws, rules and regulations. Our Bylaws also provide that any person or entity purchasing or otherwise
acquiring any interest in shares of our capital stock will be deemed to have notice of and consented to this choice of forum provision.

This choice of forum provision in our Bylaws may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes

with us or our directors, officers or other employees, which may discourage such lawsuits against us and our directors, officers and other employees. In
addition, stockholders who do bring a claim in the Court of Chancery in the State of Delaware could face additional litigation costs in pursuing any such
claim, particularly if they do not reside in or near Delaware. Furthermore, the enforceability of similar choice of forum provisions in other companies’
governing documents has been challenged in legal proceedings, and it is possible that a court could find these types of provisions to be inapplicable or
unenforceable. If a court were to find the choice of forum provision in our Bylaws to be inapplicable or unenforceable in an action, we may incur additional
costs associated with resolving such action in other jurisdictions, which could adversely affect our business and financial condition.

Compliance with changing regulations concerning corporate governance and public disclosure may result in additional expenses.

There have been changing laws, regulations and standards relating to corporate governance and public disclosure, including the Dodd-Frank Wall
Street Reform and Consumer Protection Act (the “Dodd-Frank Act”), the Sarbanes-Oxley Act of 2002 (“Sarbanes-Oxley”), new regulations promulgated
by the U.S. Securities and Exchange Commission (the “SEC”) and rules promulgated by the national securities exchanges. The Dodd-Frank Act, enacted in
July 2010, expanded federal regulation of corporate governance matters and imposes requirements on public companies to, among other things, provides
stockholders with a periodic advisory vote on executive compensation and also adds compensation committee reforms and enhanced pay-for-performance
disclosures. While some provisions of the Dodd-Frank Act were effective upon enactment, others have been and will be implemented upon the SEC’s
adoption of related rules and regulations. The scope and timing of the adoption of such rules and regulations is uncertain and, accordingly, the cost of
compliance with the Dodd-Frank Act is also uncertain. Areas subject to potential change, amendment or repeal include the Dodd-Frank Act, including §
619 (12 U.S.C. § 1851) known as the Volcker Rule and various swaps and derivatives regulations, the

65

 
authority of the Federal Reserve and the Financial Stability Oversight Council, and renewed proposals to separate banks’ commercial and investment
banking activities.

These new or changed laws, regulations and standards are, or will be, subject to varying interpretations in many cases due to their lack of specificity,

and, as a result, their application in practice may evolve over time as new guidance is provided by regulatory and governing bodies, which could result in
continuing uncertainty regarding compliance matters and higher costs necessitated by ongoing revisions to disclosure and governance practices. As a result,
our efforts to comply with evolving laws, regulations and standards are likely to continue to result in increased general and administrative expenses and a
diversion of management time and attention from revenue-generating activities to compliance activities. Members of our board of directors and our
principal executive officer and principal financial officer could face an increased risk of personal liability in connection with the performance of their
duties. As a result, we may have difficulty attracting and retaining qualified directors and executive officers, which could harm our business. If the actions
we take in our efforts to comply with new or changed laws, regulations and standards differ from the actions intended by regulatory or governing bodies,
we could be subject to liability under applicable laws or our reputation may be harmed.

If we fail to properly manage our internal control over financial reporting on a go forward basis, material weaknesses in our internal control over
financial reporting could be identified that could, if not remediated, result in a material misstatement in our financial statements and could adversely
affect our future results of operations, our stock price, and our ability to raise capital.

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 consolidated financial statements will not be prevented or detected on a timely basis.
Although we have remediated the material weaknesses that we previously identified in connection with the audit of our consolidated financial statements as
of and for the year ended December 31, 2018 by implementing and enhancing our control procedures, in order to properly manage our internal control over
financial reporting, we may need to take additional measures, and we cannot be certain that the measures we have taken, and expect to take, to improve our
internal controls will be sufficient to ensure that our internal controls will remain effective and eliminate the possibility that other material weaknesses or
deficiencies may develop or be identified in the future. If we experience future material weaknesses or deficiencies in internal controls and we are unable to
correct them in a timely manner, our ability to record, process, summarize and report financial information accurately and within the time periods specified
in the rules and forms of the SEC, will be adversely affected. Any such failure could negatively affect the market price and trading liquidity of our common
stock, lead to delisting, cause investors to lose confidence in our reported financial information, subject us to civil and criminal investigations and penalties,
and generally materially and adversely impact our business and financial condition.

Management’s Discussion and Analysis of Financial Condition and Results of Operations.

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with the financial

statements and the related notes and other information that are included elsewhere in this Annual Report on Form 10-K. This discussion contains forward-
looking statements based upon current expectations that involve risks and uncertainties, such as our plans, objectives, expectations and intentions. Actual
results and the timing of events could differ materially from those anticipated in these forward-looking statements as a result of a number of factors,
including those set forth under the cautionary note regarding “Forward-Looking Statements” contained elsewhere in this Annual Report on Form 10-K.
Additionally, you should read the “Risk Factors” section of this Annual Report on Form 10-K for a discussion of important factors that could cause actual
results to differ materially from the results described in or implied by the forward-looking statements contained in the following discussion and analysis.

Overview

Sorrento Therapeutics, Inc., together with its subsidiaries (collectively, the “Company”, “we”, “us”, and “our”) is a clinical stage and commercial

biopharmaceutical company focused on delivering innovative and clinically meaningful therapies to address unmet medical needs.

At our core, we are antibody-centric and leverage our proprietary G-MAB™ library and targeted delivery modalities to generate the next generation

of cancer therapeutics. Our fully human antibodies include PD-1, PD-L1, CD38, CD123, CD47, CTLA-4, CD137 and SARS-CoV-2 neutralizing
antibodies, among others. We also have programs assessing the use of our technologies and products in autoimmune, inflammatory, viral and
neurodegenerative diseases.

Our vision is to leverage these antibodies in conjunction with proprietary targeted delivery modalities to generate the next generation of cancer
therapeutics. These modalities include proprietary chimeric antigen receptor T-cell therapy (“CAR-T”), dimeric antigen receptor T-cell therapy (“DAR-T”),
antibody drug conjugates (“ADCs”) as well as bispecific antibody approaches. We acquired Sofusa®, a revolutionary drug delivery technology, in July
2018, which delivers biologics directly into the lymphatic system to potentially achieve improved efficacy and fewer adverse effects than standard
parenteral immunotherapy. Additionally, our majority-owned subsidiary, Scilex Holding Company (“Scilex Holding”), acquired the assets of Semnur
Pharmaceuticals, Inc. (“Semnur”) in March 2019. Semnur’s SEMDEXATM (“SP-102”) compound has the potential to become the first Food and Drug
Administration (“FDA”)-approved epidural steroid product for the treatment of sciatica. In response to the global SARS-CoV-2 (“COVID-19”) pandemic,
we are utilizing the Bruton’s tyrosine kinase (“BTK”) inhibitor (in-licensed from ACEA Therapeutics, Inc.) in a U.S. Phase II study of cytokine storm
associated with a COVID-19 infection and in a Phase II trial in Brazil in mild, moderate and severe COVID-19 patients, and we are also internally
developing potential coronavirus antiviral therapies and vaccines, including ACE-MABTM, COVIDTRAPTM, COVI-MABTM, COVI-GUARDTM, COVI-
SHIELDTM , COVI-AMG™ and T-VIVA-19TM; and diagnostic test solutions, including COVI-TRACK™, COVI-STIX™ and COVI-TRACE™.

With each of our clinical and pre-clinical programs, we aim to tailor our therapies to treat specific stages in the evolution of a disease, from

elimination, to equilibrium and escape. In addition, our objective is to focus on tumors that are resistant to current treatments and where we can design
focused trials based on a genetic signature or biomarker to ensure patients have the best chance of a durable and significant response. We have several
immuno-oncology programs that are in or near to entering the clinic. These include cellular therapies, oncolytic viruses (SeprehvecTM) and a palliative care
program targeted to treat intractable cancer pain. Our cellular therapy programs focus on CAR-T and DAR-T for adoptive cellular immunotherapy to treat
both solid and liquid tumors.

From the start of the COVID-19 pandemic, our mission has been to leverage our deep expertise in developing targeted antibodies for cancer
immunotherapy to create best-in-category treatments and diagnostics to ease suffering and assist in the global response to COVID-19. We have leveraged,
and continue to leverage, our G-MAB library and antibody development engineering capabilities to advance a number of promising diagnostics and
neutralizing antibody candidates to test and treat COVID-19 and the immune reactions associated with SARS-CoV-2 infection.

Our first generation SARS-CoV-2 neutralizing antibody was STI-1499 (COVI-GUARD™), which was engineered to prevent antibody dependent
enhancement. This antibody was then optimized to produce the highly potent STI-2020, which is currently being developed in two outpatient formations:
COVI-AMG (IV-push injection) and COVI-DROPS (nasal). COVI-AMG has been cleared by the U.S. Food and Drug Administration (“FDA”) for a Phase
I study of healthy volunteers, a Phase II study in outpatients with COVID-19 and a Phase II study in hospitalized patients with moderate or severe COVID-
19, and we are awaiting FDA clearance for a Phase I study of COVI-DROPS of healthy volunteers and patients with mild COVID-19. Sorrento also has
developed two promising potential rescue treatments with Abivertinib, an oral next generation dual EGFR/BTK inhibitor, to treat moderate to severe
hospitalized COVID-19 patients and COVI-MSC™, a human allogeneic adipose-derived mesenchymal stem cells for patients suffering from COVID-19-
induced acute respiratory distress (ARD). Both have been cleared by the FDA and are in Phase Ib clinical studies. We are also working with Brazilian
regulators (“ANVISA”) to conduct a COVID-19 study with Abivertinib and potentially with COVI-AMG TM. In pre-clinical development, we are rapidly
screening new neutralizing antibodies to address the multiple emerging variants of SARS-CoV-2 to potentially add to STI-2020 in a cocktail (COVI-
SHIELD™) and exploring novel mechanistic

69

 
approaches such as soluble recombinant fusion protein traps (COVIDTRAPTM) to potentially inhibit the binding of SARS-CoV-2’s spike protein with host
ACE2 receptors, thereby potentially preventing viral cell entry.

In furtherance of our goal to develop products across the entire continuum of COVID-19 solutions, we are further developing a number of highly
sensitive and rapid diagnostic tests. COVI-STIX™ is a lateral flow antigen test that uses a proprietary platinum-based colloid and antibody combination,
resulting in high sensitivity and accuracy. This is a simple and rapid (15-minute) test with a shallow nasal swab and is designed for point-of-care and at-
home use. COVI-TRACK™ is a rapid SARS-CoV-2 IgG/IgM antibody test kit intended for use initially in clinical laboratories and in point of care settings
to quickly identify individuals with anti-SARS-CoV-2 antibodies post-infection or post- vaccination. COVI-TRACE™ was licensed from Columbia
University as a rapid single step on-site colorimetric detection test for SARS-COV-2 genomic RNA from a saliva sample using targeted nucleic acid
amplification for high throughput point-of-care situations.

We have reported early data from Phase I trials of our carcinoembryonic antigen (“CEA”)-directed CAR-T program. We have treated five patients

with stage 4, unresectable adenocarcinoma (four with pancreatic and one with colorectal cancer) and CEA-positive liver metastases with anti-CEA CAR-T.
We successfully submitted an Investigational New Drug application (“IND”) for anti-CD38 CAR-T for the treatment of refractory or relapsed multiple
myeloma (“RRMM”), obtained clearance from the FDA and commenced a human clinical trial for this indication in early 2018. We have dosed eleven
patients. We intend to close this study to further enrollment and start up a similar anti-CD38 CAR-T construct without the myc-tag (which cannot be used
in Europe), and to continue treating RRMM patients in a Phase Ib/IIa study, which will begin enrollment in the first quarter of 2021. We filed INDs for our
CD47 mAb and the first of our DAR-T platform product candidates in the first quarter of 2021.

Broadly speaking, we believe we are one of the world’s leading CAR-T and DAR-T companies today due to our investments in technology and
infrastructure, which have enabled significant progress in developing our next-generation non-viral, “off-the-shelf” allogeneic DAR-T solutions. With “off-
the-shelf” solutions, DAR-T therapy can truly become a drug product platform rather than a treatment procedure.

With respect to our ADC program, we began enrolling patients in the first quarter of 2021 in a Phase Ib ascending dose study of our CD38 ADC for

systemic Amyloid light-chain amyloidosis. Based upon our recently announced exclusive license from Mayo Clinic for its antibody-drug-nanoparticle
albumin-bound (“ADNAB”) platform, the next generation in ADC technology, we intend to file several INDs to treat various cancer targets.

Outside of immuno-oncology programs, as part of our global aim to provide a wide range of therapeutic products to meet underserved markets, we
have made investments in non-opioid pain management. These include resiniferatoxin (“RTX”), which is a non-opioid-based toxin that specifically targets
transient receptor potential vanilloid-1 (“TRPV1”) which, depending on the site of injection, can ablate, or destroy, nerves expressing TRPV1 or
temporarily defunctionalize them. TRPV1 is responsible for the noxious chronic and inflammatory pain signaling that occurs post injury or trauma, but
leaves other nerve functions intact. RTX has been granted orphan drug status for the treatment of intractable pain with end-stage cancer and two Phase Ib
trials (intrathecal and epidural routes) in that indication have or will soon be completed. A Phase Ib trial studying tolerance and efficacy of RTX for the
control of moderate to severe osteoarthritis knee pain was initiated in late 2018 and intermediate results have shown efficacy with no dose limiting
toxicities. The osteoarthritis trial enrolled the last patient in the first quarter of 2020, and we expect to release the final safety clinical data by the middle of
2021. We plan to start knee arthritis registrational trials after the completion of required preclinical studies.

Also, in this area, we have developed in-house and acquired proprietary technologies to responsibly develop next generation, branded

pharmaceutical products to better manage patients’ medical conditions, maximize the quality of life of patients and assist healthcare providers. The flagship
product of our majority-owned subsidiary, Scilex Pharmaceuticals Inc. (“Scilex Pharma”), ZTlido® (lidocaine topical system 1.8%) (“ZTlido”), is a next-
generation lidocaine delivery system, which was approved by the FDA for the treatment of postherpetic neuralgia, a severe neuropathic pain condition in
February 2018, and was commercially launched in October 2018. Scilex Pharma has now built a full commercial organization, which includes sales,
marketing, market access and medical affairs. ZTlido has demonstrated superior adhesion in comparative head-to-head studies as compared to Lidoderm
and is manufactured by our Japanese partner in their state-of-the-art manufacturing facility.

Impact of COVID-19 on Our Business

We are closely monitoring the COVID-19 pandemic and its potential impact on our business. We are an “Essential Critical Infrastructure Provider”,

as our operations are critical to the continued operations of the healthcare infrastructure of the United States, as set forth by the U.S. Department of
Homeland Security’s Cybersecurity and Infrastructure Security Agency. In an effort to protect the health and safety of our employees, we took proactive
action from the earliest signs of the outbreak, which included implementing social distancing policies at our facilities, facilitating remote working
arrangements and imposing employee travel restrictions.

The COVID-19 pandemic has created uncertainties in the expected timelines for clinical stage biopharmaceutical companies such as ours, including

possible delays in clinical trials and disruptions in the supply chain for raw materials used in clinical trial work.

70

 
Such delays could materially impact our business in future periods. Furthermore, the spread of COVID-19, which has caused a broad impact globally, may
materially affect us economically. While the potential economic impact brought by, and the duration of, COVID-19 may be difficult to assess or predict, a
widespread pandemic could result in significant disruption of global financial markets, reducing our ability to access capital, which could in the future
negatively affect our liquidity. Policymakers around the globe have responded with fiscal policy actions to support the healthcare industries and economies
as a whole. The magnitude and overall effectiveness of these actions remain uncertain. Accordingly, the extent to which the COVID-19 global pandemic
impacts our business, results of operations and financial condition will depend on future developments, which are highly uncertain and are difficult to
predict. These developments include, but are not limited to, the duration and spread of the outbreak, its severity, the actions to contain the virus or address
its impact, U.S. and foreign government actions to respond to the reduction in global economic activity, and how quickly and to what extent normal
economic and operating conditions can resume. For more information on the risks associated with COVID-19, refer to Part I, Item 1A, “Risk Factors”
herein.

Results of Operations

The following discussion of our operating results explains material changes in our results of operations for the years ended December 31, 2020 and
2019. The discussion should be read in conjunction with the consolidated financial statements and related notes included elsewhere in this Annual Report
on Form 10-K. The Company operates in two operating and reportable segments, Sorrento Therapeutics and Scilex.

Comparison of the Years Ended December 31, 2020 and 2019

Revenues. Revenues were $40.0 million for the year ended December 31, 2020, as compared to $31.4 million for the year ended December 31,

2019.

Revenue in our Sorrento Therapeutics segment increased from $10.4 million to $13.7 million for the year ended December 31, 2020 compared to

the prior year and was primarily attributed to higher contract manufacturing service revenues.

Revenue in our Scilex segment increased from $21.0 million to $26.3 million for the year ended December 31, 2020 compared to the prior year due

to increased product sales of ZTlido.

Cost of revenues. Cost of revenues for the years ended December 31, 2020 and 2019 were $9.9 million and $12.2 million, respectively, and relate to

product sales, the sale of customized reagents and providing contract manufacturing services. The costs generally include employee-related expenses,
including salary and benefits, direct materials and overhead costs including rent, depreciation, utilities, facility maintenance and insurance.

Cost of revenues for our Sorrento Therapeutics segment increased by $1.4 million and is primarily attributable to higher contract manufacturing

service revenues.

Cost of revenues for our Scilex segment decreased by $3.7 million as compared to the prior year and is primarily attributed to the release of an

inventory provision as the result of a favorable change in shelf-life expiration requirements.

Research and development expenses. Research and development expenses for the years ended December 31, 2020 and 2019 were $111.3 million and
$106.9 million, respectively. Research and development expenses primarily include expenses associated with isolating and advancing human antibody drug
candidates derived from our libraries, as well as advancing our RTX, COVID-19, SP-102, Oncolytic Virus, antibody drug conjugate (“ADC”) and oncology
programs. Such expenses consist primarily of salaries and personnel-related expenses, stock-based compensation expense, clinical development expenses,
preclinical testing, lab supplies, consulting costs, depreciation and other expenses.

Research and development expenses for our Sorrento Therapeutics segment increased by $4.9 million as compared to the prior fiscal year and were

primarily driven by increased clinical development costs across our research and development platforms.

Research and development expenses for our Scilex segment decreased by $0.4 million as compared to the prior fiscal year and were primarily driven

by reduced costs associated with our research and development product portfolio.

We expect research and development expenses for both segments to increase as we: (i) advance various product candidates into clinical trials and

pursue other development, acquire, develop and manufacture clinical trial materials and increase other regulatory operating activities, (ii) incur incremental
expenses associated with our efforts to further advance a number of potential product candidates into preclinical development activities, (iii) continue to
identify and advance a number of fully human therapeutic antibody and ADC preclinical product candidates, (iv) incur higher salary, lab supply and
infrastructure costs in connection with supporting all of our programs, (v) invest in our joint ventures, collaborations or other third party agreements, and
(vi) expand our corporate infrastructure.

71

 
Acquired in-process research and development expenses. Acquired in-process research and development expenses for the year ended December 31,

2020 was $43.0 million. These expenses primarily related to various licensing arrangements entered into during the year, as well as other investments in
new technologies and preclinical programs. We recognized $75.3 million of expenses for the year ended December 31, 2019, which were incurred due to
acquired in-process research and development expenses associated with the acquisition of Semnur in March 2019.

Selling, general and administrative expenses. General and administrative expenses for the years ended December 31, 2020 and 2019 were $116.2

million and $103.6 million, respectively and consisted primarily of salaries and personnel-related expenses, stock-based compensation expense,
professional fees, infrastructure expenses, legal and other general corporate expenses.

Selling, general and administrative expenses for our Sorrento Therapeutics segment increased by approximately $34.7 million as compared to the

prior fiscal year and were primarily attributed to increased legal fees, professional fees and stock-based compensation expense compared to the same period
of the prior year.

Selling, general and administrative expenses for our Scilex segment decreased by approximately $22.1 million as compared to the prior fiscal year

and were primarily attributed to cost savings resulting from a more focused marketing strategy for ZTlido and savings arising from the transfer of a
contracted to in-house sales force.

Gain (loss) on derivative liabilities. Gain on derivative liabilities for the year ended December 31, 2020 was $6.6 million compared to a loss of

$36.8 million for the year ended December 31, 2019.

Gain on derivative liabilities for our Sorrento Therapeutics segment for the year ended December 31, 2020 totaled $5.8 million and was primarily

attributed to the full repayment of the term loans provided by certain funds and accounts managed by Oaktree Capital Management, L.P. (the “Term
Loans”) during 2020 as further described in Note 8 of the accompanying notes to the consolidated financial statements in this Annual Report on Form 10-
K.

Gain on derivative liabilities for our Scilex segment for the year ended December 31, 2020 was $0.8 million and was primarily attributed to revised

probabilities and revised sales forecasts as further described in Note 3 of the accompanying notes to the consolidated financial statements in this Annual
Report on Form 10-K.

Gain on contingent liabilities and acquisition consideration payable. During the year ended December 31, 2019, we recorded a gain on contingent
liabilities and acquisition consideration payable of approximately $11.1 million, which was comprised of $10.4 million attributed to the settlement of the
acquisition consideration payable associated with the acquisition of Virttu Biologics Limited and an additional $0.7 million due to changes in fair value of
other contingent liabilities.

Interest expense. Interest expense for the years ended December 31, 2020 and 2019 was $20.2 million and $36.1 million, respectively. The decrease

resulted primarily from a decrease in interest expense associated with the Term Loans.

Loss on debt extinguishment. Loss on debt extinguishment for the year ended December 31, 2020 was $51.9 million compared to $27.8 million for

the year ended December 31, 2019.

Loss on debt extinguishment for our Sorrento Therapeutics segment for the year ended December 31, 2020 totaled $51.9 million and was attributed

to the repayments of outstanding principal on the Term Loans as further described in Note 8 of the accompanying notes to the consolidated financial
statements in this Annual Report on Form 10-K. We recognized a loss on debt extinguishment of $27.8 million for the year ended December 31, 2020 due
to the conversion of the Notes associated with the March 2018 Securities Purchase Agreement as further described in Note 8.

72

 
Income tax benefit. Income tax benefit for the year ended December 31, 2020 and 2019 was $2.0 million and $0.5 million. The increase in the year

ended December 31, 2020 resulted primarily from the impact of our valuation allowance in 2020 compared to 2019.

Loss on equity method investments. Loss on equity investments for the year ended December 31, 2020 was $5.8 million compared to a loss on equity
investments of $3.9 million for the year ended December 31, 2019. The decrease was attributed to the recognition of our portion of the loss from operations
from our investments along with an impairment loss of approximately $3.8 million related to an equity method investment for which we determined the
investment’s value is no longer supportable. (See Note 5 of the accompanying notes to consolidated financial statements in this Annual Report on Form 10-
K).

Net loss. Net loss for the year ended December 31, 2020 was $314.4 million as compared to a net loss of $363.0 million for 2019.

For a discussion regarding our financial condition and results of operations for the year ended December 31, 2019 as compared to the year ended
December 31, 2018, please refer to the discussion under the heading “Results of Operations— Comparison of the Years Ended December 31, 2019 and
2018” in Item 7 of our Annual Report on Form 10-K for the fiscal year ended December 31, 2019, filed with the SEC on March 2, 2020.

Liquidity and Capital Resources

As of December 31, 2020, we had $56.5 million in cash and cash equivalents attributable in part to the following financing arrangements:

Debt Financings

2018 Oaktree Term Loan Agreement

In November 2018, we entered into a Term Loan Agreement (the “Loan Agreement”) with certain funds and accounts managed by Oaktree Capital

Management, L.P. (collectively, the “Lenders”) and Oaktree Fund Administration, LLC, as administrative and collateral agent, for an initial term loan of
$100.0 million (the “Initial Loan”). In May 2019, we entered into an amendment to the Loan Agreement, under which terms the Lenders agreed to make
available to us $20.0 million (collectively, with the Initial Loan, the “Term Loans”). During the year ended December 31, 2020, we repaid $120.0 million
of the outstanding principal under the Term Loans plus approximately $9.4 million of related prepayment premium, exit fees and accrued interest thereon.

Scilex Notes

Scilex Pharma entered into purchase agreements (the “2018 Purchase Agreements”) with certain investors (collectively, the “Scilex Note

Purchasers”) and us. Pursuant to the 2018 Purchase Agreements, on September 7, 2018, Scilex Pharma issued and sold to the Scilex Note Purchasers senior
secured notes due 2026 in an aggregate principal amount of $224.0 million (the “Scilex Notes”) for an aggregate purchase price of $140.0 million (the
“Scilex Notes Offering”). In connection with the Scilex Notes Offering, Scilex Pharma also entered into an Indenture (the “Indenture”) governing the
Scilex Notes with U.S. Bank National Association, a national banking association, as trustee and collateral agent, and us. Pursuant to the Indenture, we
agreed to irrevocably and unconditionally guarantee, on a senior unsecured basis, the punctual performance and payment when due of all obligations of
Scilex Pharma under the Indenture.

We identified a number of embedded derivatives that require bifurcation from the Scilex Notes and were separately accounted for in the

consolidated financial statements as derivative liabilities. Certain of these embedded features include default interest provisions, contingent rate increases,
contingent put options, optional and automatic acceleration provisions and tax indemnification obligations. The fair value of the derivative liabilities
associated with the Scilex Notes was estimated using the discounted cash flow method under the income approach combined with a Monte Carlo
simulation model. This involves significant Level 3 inputs and assumptions, including a risk adjusted net sales forecast, an effective debt yield, estimated
marketing approval probabilities for SP-103 and an estimated probability of an initial public offering by Scilex Holding that satisfies certain valuation
thresholds and timing considerations. We re-evaluate this assessment each reporting period.

The 2018 Purchase Agreements and Indenture provide that, upon the occurrence of an event of default, the lenders thereunder may, by written notice

to us, declare all of the outstanding principal and interest under the Indenture immediately due and payable. For purposes of the Indenture, an event of
default includes, among other things, (i) a failure to pay any amounts when due under the Indenture, (ii) a breach or other failure to comply with the
covenants (including financial, notice and reporting covenants) under the Indenture, (iii) a failure to make any payment on, or other event triggering an
acceleration under, other material indebtedness of us,

73

 
and (iv) the occurrence of certain insolvency or bankruptcy events (both voluntary and involuntary) involving us or certain of our subsidiaries. We are
subject to certain customary default clauses under the Indenture and are in compliance with the event of default clauses under the Indenture.

On December 14, 2020, we, Scilex Pharma, the Company, U.S. Bank National Association, a national banking association, as trustee (the “Trustee”)

and collateral agent, and the beneficial owners of the Scilex Notes and the Scilex Note Purchasers entered into a Consent Under and Amendment No. 3 to
Indenture and Letter of Credit (the “Amendment”), which amended: (i) the Indenture, and (ii) the Letter of Credit.

On December 14, 2020, and in connection with the Amendment, the aggregate $45.0 million in restricted funds held in previously established
reserve and collateral accounts were released and Scilex Pharma utilized such funds to repurchase an aggregate of $45.0 million in principal amount of the
Scilex Notes. Scilex Pharma also repurchased an aggregate of $20.0 million in principal amount of the Scilex Notes on December 16, 2020. Pursuant to the
foregoing repurchases, the aggregate principal amount of the Scilex Notes was reduced by an aggregate of $65.0 million.

Equity Financings

Universal Shelf Registration Statement

In March 2020, we filed a universal shelf registration statement on Form S-3 (the “Shelf Registration Statement”) with the SEC, which was declared

effective by the SEC on March 20, 2020. The Shelf Registration Statement provides us with the ability to offer up to $1.0 billion of securities, including
equity and other securities as described in the registration statement. Pursuant to the Shelf Registration Statement, we may offer such securities from time
to time and through one or more methods of distribution, subject to market conditions and our capital needs. Specific terms and prices will be determined at
the time of each offering under a separate prospectus supplement, which will be filed with the SEC at the time of any offering. As of December 31, 2020,
approximately $292.0 million of securities remain available and unallocated for offerings of securities under the Shelf Registration Statement after
reserving for the Amended Sales Agreement (discussed below).

Common Stock Purchase Agreement

In April 2020, we entered into a Common Stock Purchase Agreement (the “Purchase Agreement”) with Arnaki Ltd. (the “Purchaser”), pursuant to

which the Purchaser was committed to purchase up to an aggregate of $250.0 million of shares of our common stock over the 36-month term of the
Purchase Agreement. During the year ended December 31, 2020, we sold an aggregate of 1,423,077 shares of our common stock pursuant to the Purchase
Agreement for aggregate net proceeds of $8.0 million. Effective October 27, 2020, we voluntarily terminated the Purchase Agreement. The Purchase
Agreement was terminable at will by us with no penalty.

Amended Sales Agreement

On December 4, 2020, we entered into Amendment No. 1 (the “Amendment”) to that certain Sales Agreement dated April 27, 2020 (the “Sales
Agreement”), with A.G.P./Alliance Global Partners (the “Agent”). The Sales Agreement provided that we could offer and sell through or to the Agent up to
$250.0 million in shares of its common stock. The Amendment amends the Sales Agreement to provide that we may offer and sell, from time to time,
through or to the Agent, up to an additional $450.0 million in shares of our common stock (the “Additional Shares”), such that we may offer and sell up to
an aggregate of $700.0 million in shares of our common stock (the “Offering”) pursuant to the Sales Agreement, as amended by Amendment No. 1 (the
“Amended Sales Agreement”). We have no obligation to sell any shares of our common stock pursuant to the Amended Sales Agreement and may at any
time suspend offers under the Amended Sales Agreement. The Offering will terminate upon (i) the election of the Agent upon the occurrence of certain
adverse events, (ii) three business days’ advance notice from one party to the other, or (iii) the sale of all $700.0 million of shares of our common stock
pursuant thereto. Under the terms of the Amended Sales Agreement, the Agent will be entitled to a commission at a fixed rate of 3.0% of the gross
proceeds from each sale of shares of our common stock under the Amended Sales Agreement.

During the year ended December 31, 2020, we sold an aggregate of 30,991,918 shares of our common stock pursuant to the Amended Sales

Agreement for aggregate net proceeds to us of approximately $227.7 million.

Purchase Agreement with Aspire Capital

In February 2020, we entered into a Common Stock Purchase Agreement (the “Aspire Purchase Agreement”) with Aspire Capital Fund, LLC

(“Aspire Capital”), pursuant to which Aspire Capital was committed to purchase up to an aggregate of

74

 
$75.0 million of shares of our common stock over a 24-month term. Upon execution of the Aspire Purchase Agreement, we issued to Aspire Capital
897,308 shares of our common stock as a commitment fee. We have used the proceeds we receive under the Aspire Purchase Agreement for working
capital and general corporate purposes and for the repayment of debt. The Aspire Purchase Agreement was terminable by us at any time without any
liability to us. Generally, Aspire Capital could terminate the Aspire Purchase Agreement at any time that an event of default existed. During the year ended
December 31, 2020, we issued and sold an aggregate of 38,825,010 shares of our common stock to Aspire Capital under the Aspire Purchase Agreement
for aggregate net proceeds of approximately $75.0 million. On April 24, 2020, the Aspire Purchase Agreement terminated effective immediately in
accordance with its terms as we had issued and sold, as of such date, the full $75.0 million of shares available for issuance thereunder.

Contingent Consideration

We have contingent consideration obligations in connection with certain acquisition and licensing transactions that are contingent upon achieving

certain specified milestones or the occurrence of certain events, including those described within the accompanying notes to the consolidated financial
statements of this Form 10-K. Upon the achievement of such milestones or the occurrence of such events, we will be obligated to make certain cash or
stock payments in accordance with the terms of such acquisition and license agreements.

Use of Cash

Cash Flows from Operating Activities. Net cash used for operating activities was $159.5 million for 2020 as compared to $173.0 million for 2019.

Net cash used reflects the cash spent on our research activities and cash spent to support the commercial launch of our products.

We expect to continue to incur substantial and increasing losses and negative net cash flows from operating activities as we seek to expand and

support our clinical and pre-clinical research and development activities and support the commercial launch of our products.

Cash Flows from Investing Activities. Net cash used for investing activities was $39.9 million for the year ended December 31, 2020. We invested

approximately $31.1 million in licensing arrangements, which are further described in Note 7 of the accompanying notes to the consolidated financial
statements in this Annual Report on Form 10-K. We also invested approximately $2.3 million in new technologies and preclinical programs and spent
approximately $7.2 million on equipment and building improvements. During the year ended December 31, 2019, net cash used by investing activities was
$38.2 million and was attributed to $17.0 million associated with the Semnur acquisition, $11.4 million for equipment and building improvements and $1.2
million in capital contributions to joint ventures related to our preclinical programs.

Cash Flows from Financing Activities. Net cash provided by financing activities was $174.2 million for 2020 as compared to $78.9 million for 2019.
During the year ended December 31, 2020, we received $317.9 million from equity offerings, proceeds from short-term debt of $18.6 million and proceeds
of $98.4 million from common stock issuances and warrant exercises. During the year ended December 31, 2020, we repaid $120.0 million of outstanding
principal under the Term Loans, paid $6.3 million of related exit and prepayment fees thereon, made payments of $69.8 million on the Scilex Notes and
repaid $9.4 million in short-term debt. We also paid $55.0 million related to the Semnur Share Exchange as further described in Note 7 of the
accompanying notes to the consolidated financial statements in this Annual Report on Form 10-K. During the same period in the prior year, cash provided
by financing activities was primarily driven by proceeds from equity offerings of approximately $46.7 million, $9.8 million from common stock issuances
and warrant exercises and $18.9 million in debt financing, net of issuance costs, from the Term Loans.

Future Liquidity Needs. We have principally financed our operations through underwritten public offerings and private debt and equity financings,
as we have not generated any significant product related revenue from our principal operations to date. We will need to raise additional capital before we
exhaust our current cash resources in order to continue to fund our research and development, including our plans for clinical and preclinical trials and new
product development, as well as to fund operations generally. We will seek to raise additional funds through various potential sources, such as equity and
debt financings or through corporate collaboration, grant agreements and license agreements. We can give no assurances that we will be able to secure such
additional sources of funds to support our operations, or, if such funds are available to us, that such additional financing will be sufficient to meet our
needs. These conditions, among others, raise substantial doubt about our ability to continue as a going concern.

We cannot be certain that additional funding will be available on acceptable terms, or at all. If we issue additional equity securities to raise funds, the

ownership percentage of existing stockholders would be reduced. New investors may demand rights, preferences or privileges senior to those of existing
holders of common stock. If we are unable to raise additional capital in sufficient amounts or on terms acceptable to us, we may have to significantly delay,
scale back or discontinue the development or

75

 
commercialization of one or more of our product candidates. We may also seek collaborators for one or more of our current or future product candidates at
an earlier stage than otherwise would be desirable or on terms that are less favorable than might otherwise be available. These factors raise substantial
doubt about our ability to continue as a going concern. Our financial statements and related notes thereto included elsewhere in this Annual Report on
Form 10-K do not include any adjustments that might result from the outcome of these uncertainties.

We anticipate that we will continue to incur net losses into the foreseeable future as we: (i) advance our product pipeline and other product
candidates into clinical trials, (ii) continue our development of, and seek regulatory approvals for, our product candidates in clinical trials, (iii) expand our
corporate infrastructure, and (iv) incur our share of joint venture and collaboration costs for our products and technologies.

Uses of Cash. We have and plan to expand our business and intellectual property portfolio through the acquisition of new businesses and

technologies as well as entering into licensing arrangements.

Critical Accounting Estimates

Our consolidated financial statements are prepared in accordance with U.S. GAAP. The preparation of these consolidated financial statements
requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, expenses and related disclosures. We evaluate
our estimates and assumptions on an ongoing basis. Our estimates are based on historical experience and various other assumptions that we believe to be
reasonable under the circumstances. Our actual results could differ from these estimates.

We believe the following accounting policies and estimates are most critical to aid in understanding and evaluating our reported financial results.

Revenue Recognition. Our revenues are generated from product revenues, the sale of customized reagents and other materials, contract
manufacturing services, grant revenue and other service revenues. We do not have significant costs associated with costs to obtain contracts with our
customers. Substantially all of our revenues and accounts receivable result from contracts with customers.

We recognize revenue when control of the products is transferred to the customers in an amount that reflects the consideration we expect to receive

from the customers in exchange for those products and services. This process involves identifying the contract with a customer, determining the
performance obligations in the contract and the contract price, allocating the contract price to the distinct performance obligations in the contract and
recognizing revenue when the performance obligations have been satisfied. A performance obligation is considered distinct from other obligations in a
contract when it provides a benefit to the customer either on its own or together with other resources that are readily available to the customer and is
separately identified in the contract. We consider a performance obligation satisfied once we have transferred control of a good or service to the customer,
meaning the customer has the ability to use and obtain the benefit of the good or service. We recognize revenue for satisfied performance obligations only
when no significant reversals are expected. (See Note 1 of the accompanying notes to the consolidated financial statements in this Annual Report on Form
10-K).

Investments in Other Entities. We hold a portfolio of investments in equity securities. Investments in entities over which we have significant

influence but not a controlling interest are accounted for using the equity method, with our share of earnings or losses reported in loss on equity
investments. Our other equity investments are carried at cost, less impairment, plus or minus changes resulting from observable price changes in orderly
transactions for identical or similar investments.

All investments are reviewed on a regular basis for possible impairment. If an investment’s fair value is determined to be less than its net carrying

value and the decline is determined to be other-than-temporary, the investment is written down to its fair value. Such an evaluation is judgmental and
dependent on specific facts and circumstances. Factors considered in determining whether an other-than-temporary decline in value has occurred include:
the magnitude of the impairment and length of time that the estimated market value was below the cost basis; financial condition and business prospects of
the investee; our intent and ability to retain the investment for a sufficient period of time to allow for recovery in market value of the investment; issues that
raise concerns about the investee’s ability to continue as a going concern; any other information that we may be aware of related to the investment. We do
not report the fair value of our equity investments in non-publicly traded companies because it is not readily determinable.

Debt, Including Debt With Detachable Warrants. Debt with detachable warrants are evaluated for the classification of warrants as either equity
instruments, derivative liabilities, or liabilities depending on the specific terms of the warrant agreement. In circumstances in which debt is issued with
equity-classified warrants, the proceeds from the issuance of convertible debt are first allocated to the debt and the warrants at their relative estimated fair
values. The portion of the proceeds so allocated to the warrants are

76

 
accounted for as paid-in capital and a debt discount. The remaining proceeds, as further reduced by discounts created by the bifurcation of embedded
derivatives and beneficial conversion features, are allocated to the debt. We account for debt as liabilities measured at amortized cost and amortize the
resulting debt discount from the allocation of proceeds, to interest expense using the effective interest method over the expected term of the debt
instrument. We consider whether there are any embedded features in debt instruments that require bifurcation and separate accounting as derivative
financial instruments pursuant to Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 815, Derivatives and
Hedging. Embedded features that require bifurcation are initially and subsequently measured at fair value. See Note 3 of the accompanying notes to the
consolidated financial statements in this Annual Report on Form 10-K for additional discussion on the derivative liabilities associated with embedded
features in our debt instruments.

If the amount allocated to the convertible debt results in an effective per share conversion price less than the fair value of our common stock on the
commitment date, the intrinsic value of this beneficial conversion feature is recorded as a discount to the convertible debt with a corresponding increase to
additional paid in capital. The beneficial conversion feature discount is equal to the difference between the effective conversion price and the fair value of
our common stock at the commitment date, unless limited by the remaining proceeds allocated to the debt.

We may enter financing arrangements, the terms of which involve significant assumptions and estimates, including future net product sales, in

determining interest expense, amortization period of the debt discount, as well as the classification between current and long-term portions. In estimating
future net product sales, we assess prevailing market conditions using various external market data against our anticipated sales and planned commercial
activities. Consequently, we impute interest on the carrying value of the debt and record interest expense using an imputed effective interest rate. We
reassess the expected payments each reporting period and account for any changes through an adjustment to the effective interest rate on a prospective
basis, with a corresponding impact to the classification of our current and long-term portions.

Acquired In-Process Research and Development Expense. We have acquired and may continue to acquire the rights to develop and commercialize
new drug candidates. The up-front payments to acquire a new drug compound or drug delivery devices, as well as future milestone payments associated
with asset acquisitions that do not meet the definition of a derivative and are deemed probable to achieve the milestones, are immediately expensed as
acquired in-process research and development provided that the drug has not achieved regulatory approval for marketing and, absent obtaining such
approval, have no alternative future use. Intangible assets acquired in a business combination that are used for in-process research and development
activities are considered indefinite lived until the completion or abandonment of the associated research and development efforts. Upon commercialization
of the relevant research and development project, the Company amortizes the acquired in-process research and development over its estimated useful life.
Capitalized in-process research and development is reviewed annually for impairment or more frequently as changes in circumstance or the occurrence of
events suggest that the remaining value may not be recoverable.

Item 7A.

Quantitative and Qualitative Disclosures About Market Risk.

Interest Rate Risk. Our exposure to market risk is confined to our cash and cash equivalents and debt. We have cash and cash equivalents and invest

primarily in high-quality money market funds, which we believe are subject to limited credit risk. Due to 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 portfolio. We do not believe that we have any
material exposure to interest rate risk arising from our investments and we do not use derivative financial instruments to hedge against interest rate risk.  

We are not subject to interest rate risk on the Scilex Notes associated with our 2018 Purchase Agreements as repayment of the Scilex Notes is
determined by projected net sales as further discussed in Note 8 of the accompanying notes to the consolidated financial statements in this Annual Report
on Form 10-K. For the Scilex Notes, changes in interest rates will generally affect the fair value of the debt instrument, but not our earnings or cash flows. 

Capital Market Risk. We currently do not have significant revenues from grants or sales and services and we have no product revenues from our

planned principal operations and therefore depend on funds raised through other sources. One source of funding is through future debt or equity offerings.
Our ability to raise funds in this manner depends upon, among other things, capital market forces affecting our stock price.

Concentration Risk. During the fiscal years ended December 31, 2020, 2019 and 2018, sales to the sole customer and third-party logistics

distribution provider of Scilex Pharma, Cardinal Health, represented 100% of the net revenue of Scilex Pharma. This exposes us to concentration of
customer risk. We monitor the financial condition of the sole customer of Scilex Pharma, limit our credit exposure by setting credit limits, and did not
experience any credit losses for the years ended December 31, 2020, 2019 and 2018. As we continue to expand the commercialization of ZTlido, we are
not limited to the current customer and have the option of expanding our distribution network with additional distributors through establishing our own
affiliates, by acquiring existing third-party business or product rights or by partnering with additional third parties.

Controls and Procedures.

Disclosure Controls and Procedures

We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our reports filed under the

Securities Exchange Act of 1934, as amended (the “Exchange Act”), is recorded, processed, summarized and reported within the time periods specified in
the SEC’s regulations, rules and forms and that such information is accumulated and communicated to our management, including our Chief Executive
Officer (“CEO”) and Chief Financial Officer (“CFO”), as appropriate, to allow for timely decisions regarding required disclosure.

An evaluation was conducted under the supervision and with the participation of our management, including the CEO and CFO, on the effectiveness

of our disclosure controls and procedures, as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act. Based on this evaluation, our
CEO and CFO concluded that our disclosure controls and procedures were effective as of the end of the period covered by this Annual Report on Form 10-
K.

Management’s Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in

Exchange Act Rule 13a-15(f). Under the supervision and with the participation of our management, including our CEO and our CFO, we conducted an
evaluation of the effectiveness of our internal control over financial reporting based on the framework in Internal Control – Integrated Framework (2013)
issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on the evaluation of our disclosure controls and procedures
under this framework, our CEO and CFO have concluded that our internal control over financial reporting was effective as of December 31, 2020.

The effectiveness of our internal control over financial reporting at December 31, 2020 has also been audited by Ernst & Young LLP, an

independent registered public accounting firm, as stated in their report included in this Annual Report on Form 10-K.

78

 
Inherent Limitations over Internal Controls

Our internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the

preparation of consolidated financial statements for external purposes in accordance with generally accepted accounting principles. Our internal control
over financial reporting includes those policies and procedures that:

(1)

(2)

(3)

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 our receipts and expenditures are being made in accordance with authorizations of
management and directors; 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.

Internal control over financial reporting cannot provide absolute assurance of achieving financial reporting objectives because of its inherent

limitations, including the possibility of human error and circumvention by collusion or overriding of controls. Accordingly, even an effective internal
control system may not prevent or detect material misstatements on a timely basis. Additionally, 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.

Changes in Internal Control Over Financial Reporting

There were no changes to our internal control over financial reporting (as defined in Rules 13a-15(f) and 15-d-15(f) under the Exchange Act) that
occurred during the quarter ended December 31, 2020 that have materially affected, or are reasonably likely to materially affect, our internal control over
financial reporting.

Executive Compensation.

Compensation Discussion and Analysis

Compensation Philosophy

The primary goals of our Board with respect to executive compensation are to attract and retain talented and dedicated executives, to tie annual and
long-term cash and stock incentives to achievement of specified performance objectives, and to create incentives resulting in increased stockholder value.
To achieve these goals, our Compensation Committee recommends to our Board executive compensation packages, generally comprising a mix of salary,
discretionary bonus and equity awards. Although we have not adopted any formal guidelines for allocating total compensation between equity
compensation and cash compensation, we have implemented and maintain compensation plans that tie a substantial portion of our executives’ overall
compensation to achievement of corporate goals.

Role of Compensation Consultant

The Compensation Committee has the power to engage independent advisors to assist it in carrying out its responsibilities. In 2020, the

Compensation Committee re-engaged Compensia, Inc. (“Compensia”), a national compensation consulting firm, to review and advise on our compensation
practices. The Compensation Committee assessed the independence of Compensia pursuant to SEC rules and concluded that the work of Compensia has
not raised any conflict of interest.

In 2020, Compensia undertook the following projects for the Compensation Committee:

•

•

•

June 2020 - Evaluated the compensation arrangements for the Company’s executive and other officers against a comparable group of similar
life sciences companies and its own proprietary data;

June 2020 - Evaluated the compensation arrangements for the members of the Company’s Board of Directors against a comparable group of
similar life sciences companies and its own proprietary data; and

January - August 2020 - Assisted the Compensation Committee in developing the CEO Performance Award (discussed in more detail below
and approved by our stockholders at our 2020 annual meeting of stockholders held in October 2020).

With respect to the compensation decisions for our executive officers for 2020, including the option award granted and salary increase to our Chief

Executive Officer in June 2020 and the option award granted to our then-current Chief Financial Officer in June 2020, the comparable group of life
sciences companies consisted of the following companies, determined to: (i) generally have similar revenues as us; (ii) generally have similar market
capitalization as us, (iii) generally have similar operating income as us, and (iv) generally have the same number of employees as us:

Adaptimmune Therapeutics PLC.

Mersana Therapeutics, Inc.

Allogene Therapeutics, Inc.

Momenta Pharmaceuticals, Inc.

ChemoCentryx, Inc.

Epizyme, Inc.

Fate Therapeutics, Inc.

ImmunoGen, Inc.

NantKwest, Inc.

Novavax, Inc.

Sage Therapeutics, Inc.

Sangamo Therapeutics, Inc.

Inovio Pharmaceuticals, Inc.

Veracyte, Inc.

Karyopharm Therapeutics, Inc.

Vir Biotechnology, Inc.

MacroGenics, Inc.

Xencor, Inc.

In 2020, Compensia reviewed and advised the Compensation Committee on the matters described above.

In setting 2020 compensation, the Compensation Committee reviewed the competitive market analysis provided by Compensia in 2020 and
compared each named executive officer’s base salary, target annual performance bonus and equity compensation value, separately and in the aggregate, to
amounts paid to similarly-situated executives at our peer companies. The Compensation Committee believes that targeting compensation towards similarly
situated executives at our peer companies helps achieve the compensation objectives described above. However, compensation for each named executive
officer may vary from this range depending on other factors the Compensation Committee considers relevant, such as internal pay equity among our named
executive officers or levels of authority, responsibility and experience of our named executive officers that exceed the norms for individuals holding
comparably-titled positions at other companies.

With respect to the option award granted to our Chief Executive Officer by Scilex Holding Company in December 2020, the decision to grant such

options was approved by the Compensation Committee of the Board of Directors of Scilex Holding Company, which is comprised solely of an independent
director that is also not on our Board or an officer or employee of our company. Dr. Ji has agreed to forego and relinquish his December 2020 option to
purchase 7,844,554 shares of common stock of Scilex Holding Company if it is not approved by our stockholders at our 2021 annual meeting of
stockholders.

Elements of Compensation

We evaluate individual executive performance with a goal of setting compensation at levels our Board or any applicable committee thereof believes

are comparable with executives in other companies of similar size and stage of development while taking into account our relative performance and our
own strategic goals. The compensation received by our named executive officers consists of the following elements:

Base Salary

Base salaries for our executives are established based on the scope of their responsibilities and individual experience, taking into account

competitive market compensation paid by other companies for similar positions within our industry.

The Compensation Committee considers compensation data from the peer companies to the extent the executive positions at these companies are

considered comparable to our positions and informative of the competitive environment. Compensation data for our peer group were collected from
available proxy-disclosed data. This information was gathered and analyzed for the 25th, 50th and 75th percentiles for annual base salary, short-term
incentive pay elements and long-term incentive pay elements.

The amended and restated employment agreement between us and Dr. Ji, dated May 9, 2017, provides for an annual base salary for Dr. Ji of
$600,000, as may be adjusted from time to time. Based on a review of Dr. Ji’s individual performance since joining us in 2006 and the competitive market
base pay data for chief executive officers included in our peer group in the May 2018 Report, effective May 29, 2018, the Compensation Committee
increased Dr. Ji’s annual base salary from $600,000 to $670,000 with retroactive effect to January 1, 2018. Dr. Ji’s salary was not adjusted, and remained
$670,000, during all of 2019. In June 2020, after considering the competitive market analysis provided by Compensia in 2020, the Compensation
Committee increased Dr. Ji’s annual base salary to $700,000, with retroactive effect to January 1, 2020.

The offer letter between us and Mr. Asghar, our Senior Vice President and Chief Financial Officer, dated April 24, 2019, provided for an annual base

salary of $300,000, as may be adjusted from time to time. In October 2020, the Compensation Committee considered the competitive market analysis
provided by Compensia in 2020 and increased Mr. Asghar’s annual base salary to $400,000, retroactive to August 18, 2020, the effective date of his
promotion to the role of Senior Vice President and Chief Financial Officer.

The offer letter between us and Mr. Shao, our former Executive Vice President and Chief Financial Officer, dated March 15, 2018, provided for an
annual base salary for Mr. Shao of $450,000, as could be adjusted from time to time. Mr. Shao’s salary was not adjusted, and remained $450,000 for all of
2020 through the termination of his employment in August 2020.

Variable Pay

We design our variable pay programs to be both affordable and competitive in relation to the market. We monitor the market and adjust our variable

pay programs as needed. Our variable pay programs, such as our bonus program, are designed to motivate employees to achieve overall goals. Our
programs are designed to avoid entitlements, to align actual payouts with the actual results achieved and to be easy to understand and administer.

Bonuses

For 2020, Dr. Ji’s target annual bonus was equal to 80% of his annual salary, which the Compensation Committee set in June 2020 after considering

the competitive market analysis provided by Compensia in 2020. Our offer letter with Mr. Asghar provided that Mr. Asghar’s annual target bonus was
equal to 30% of his annual salary, which the Compensation Committee increased to 40% in October 2020 after considering the competitive market analysis
provided by Compensia in 2020 and Mr. Asghar’s promotion in August 2020.

As of the date of the filing of this Annual Report on Form 10-K, the Compensation Committee has not yet determined the annual bonus amounts, if

any, that will be awarded our named executive officers for 2020. We expect the Compensation Committee to assess 2020 performance and determine the
2020 annual bonus awards for our executive officers in the second half of 2021. Once such annual bonus amounts, if any, have been determined, we will, in
accordance with Securities and Exchange Commission rules and regulations, file a Current Report on Form 8-K or otherwise disclose the 2020 annual
bonus amounts within four business days after the Compensation Committee has assessed 2020 performance and determined the 2020 annual bonus awards
for our named executive officers.

85

 
Equity-Based Incentives

Salaries and bonuses are intended to compensate our executive officers for short-term performance. We also have adopted an equity incentive

program intended to reward longer-term performance and to help align the interests of our named executive officers with those of our stockholders. We
believe that long-term performance is achieved through an ownership culture that rewards performance by our named executive officers through the use of
equity incentives. Our equity incentive plan has been established to provide our employees, including our named executive officers, with incentives to help
align those employees’ interests with the interests of our stockholders.

When making equity-award decisions, the Compensation Committee considers market data, the grant size, the forms of long-term equity
compensation available to it under our existing plans and the status of previously granted awards. The amount of equity incentive compensation granted
reflects the executives’ expected contributions to our future success. Existing ownership levels are not a factor in award determination, as the
Compensation Committee does not want to discourage executives from holding significant amounts of our stock.

Future equity awards that we make to our named executive officers will be driven by our sustained performance over time, our named executive
officers’ ability to impact our results that drive stockholder value, their level of responsibility, their potential to fill roles of increasing responsibility, and
competitive equity award levels for similar positions in comparable companies. Equity forms a key part of the overall compensation for each executive
officer and is evaluated each year as part of the annual performance review process and incentive payout calculation.

The amounts awarded to the named executive officers are based on the Compensation Committee’s subjective determination of what is appropriate

to incentivize the executives. Generally, the grants to named executive officers vest over: (i) a four-year period with 25% vesting on each anniversary of the
grant date, or (ii) a four-year period with 1/4 of the shares vesting on the first anniversary of the applicable vesting commencement date, and 1/48 of the
shares vesting thereafter on a monthly basis. All equity awards to our employees, including named executive officers, and to directors have been granted
and reflected in our financial statements, based upon the applicable accounting guidance, with the exercise price equal to the fair market value of one share
of common stock on the grant date.

In order to encourage a long-term perspective and to encourage key employees to remain with us, our stock options typically have annual vesting

over a four-year period and a term of ten years. Generally, vesting ends upon termination of services and exercise rights of vested options cease three
months after termination of services. Prior to the exercise of an option, the holder has no rights as a stockholder with respect to the shares subject to such
option, including voting rights and the right to receive dividends or dividend equivalents.

In June 2020, the Compensation Committee determined to grant to Dr. Ji and Mr. Shao a long-term equity based incentive in the form of an option
to purchase 1,500,000 shares of our common stock and 120,000 shares of our common stock, respectively. The Compensation Committee considered the
competitive market analysis provided by Compensia in 2020 and other data, including the fact that no annual bonus had yet been awarded to Dr. Ji or Mr.
Shao for 2019, in determining the number of options granted to Dr. Ji and Mr. Shao in June 2020. In November 2020, Mr. Asghar was granted a long-term
equity based incentive in the form of option to purchase 120,000 shares of our common stock. This grant was made in connection with Mr. Asghar’s
promotion to the role of Senior Vice President and Chief Financial Officer in August 2020 and the Compensation Committee also considered the
competitive market analysis provided by Compensia in 2020 in determining the number of options granted to Mr. Asghar. It is our view that option-based
awards best align with the interest of our stockholders.

In addition, in December 2020, Scilex Holding Company granted to Dr. Ji and Mr. Asghar an option to purchase 7,844,554 and 750,000 shares of its
common stock, respectively. In determining the number of options to grant to Dr. Ji and Mr. Asghar, the Scilex Holding Company board and compensation
committee considered recommendations by a third party compensation study. Dr. Ji’s option to purchase shares of Scilex Holding Company provides that
Dr. Ji will forego and relinquish his right to receive the option if it is not approved by our stockholders. Our stockholders will consider the Scilex Holding
Company option award grant to Dr. Ji at our 2021 annual meeting of stockholders. The equity awards granted by us and Scilex Holding Company to our
named executive officers in 2020 are set forth in the 2020 Summary Compensation Table and Grants of Plan-Based Awards During Fiscal Year 2020 table
contained herein.

CEO Performance Award

On August 7, 2020, the Compensation Committee approved a grant to Dr. Ji of a 10-year CEO performance award tied solely to achieving market
capitalization milestones (the “CEO Performance Award”) which was approved by our stockholders at the 2020 Annual Meeting of Stockholders held on
October 16, 2020. The CEO Performance Award consists of a 10-year option to purchase an aggregate of 24,935,882 shares of our common stock, which
was equal to 10% of our outstanding shares of common stock on the day

86

 
prior to the date of grant, and vests in ten tranches. Each of the ten tranches vests only if a market capitalization milestone is achieved, which requires two
market capitalization prongs to be met to achieve each milestone: (1) a six calendar month trailing average (based on trading days); and (2) a 30 calendar
day trailing average (based on trading days). To meet the first market capitalization milestone, our current market capitalization must increase to $5.0
billion. For the next two milestones, our market capitalization must continue to increase in additional $2.0 billion increments. For the three milestones
thereafter, our market capitalization must increase in additional $3.0 billion increments. For the next three milestones thereafter, our market capitalization
must increase in additional $4.0 billion increments. For the final milestone, our market capitalization must increase by an additional $5.0 billion. Thus, for
Dr. Ji to fully vest in the award, our market capitalization must increase to $35.0 billion. The exercise price per share subject to the CEO Performance
Award is $17.30, which is a 20% premium to the closing sales price of our common stock on August 7, 2020, the date the CEO Performance Award was
approved by the Compensation Committee.

Benefits Programs

We design our benefits programs to be both affordable and competitive in relation to the market while conforming with local laws and practices. We
monitor the market and local laws and practices and adjust our benefits programs as needed. We design our benefits programs to provide an element of core
benefits and, to the extent possible, offer options for additional benefits, be tax-effective for employees in each country and balance costs and cost sharing
between us and our employees.

Timing of Equity Awards

Only the Compensation Committee may approve stock option grants to our executive officers. Stock options are generally granted at meetings of the
Compensation Committee or pursuant to a unanimous written consent of the Compensation Committee. The exercise price of a newly granted option is the
closing price of our common stock on the date of grant.

Executive Equity Ownership

We encourage our executives to hold a significant equity interest in our company. However, we do not have specific share retention and ownership

guidelines for our executives.

Hedging Policy

Our Insider Trading and Window Period Policy prohibits our directors, officers and employees, and their family members, from engaging in hedging

transactions involving our securities.

Consideration of Advisory Votes to Approve the Compensation of our Named Executive Officers

We value the opinions of our stockholders, including as expressed through advisory votes to approve the compensation of our named executive

officers (“Say-on-Pay Votes”). In our most recent Say-On-Pay Vote, conducted at our 2018 annual meeting of stockholders, held on August 24, 2018, our
stockholders approved the compensation of our named executive officers on an advisory basis, with approximately 90% of the votes cast in favor of the
fiscal 2017 compensation of our named executive officers. In setting fiscal 2019 compensation, we considered the outcome of the Say-on-Pay Vote during
our 2018 annual meeting of stockholders and will continue to consider the outcome of future Say-on-Pay Votes, as well as stockholder feedback received
throughout the year, when making compensation decisions for our executive officers.

Effect of Accounting and Tax Treatment on Compensation Decisions

In the review and establishment of our compensation programs, we consider the anticipated accounting and tax implications to us and our

executives.

Generally, Section 162(m) of the Code disallows public companies a tax deduction for federal income tax purposes of compensation in excess of $1

million paid to their chief executive officer and certain other specified officers in any taxable year. For tax years ending prior to December 31, 2017,
compensation in excess of $1 million could only be deducted if it was “performance-based compensation” within the meaning of Section 162(m) of the
Code or qualified for one of the other exemptions from the deduction limit. The exemption from Section 162(m) of the Code’s deduction limit for
performance-based compensation has been repealed, effective for taxable years beginning after December 31, 2017, such that compensation paid to our
covered officers (which now also includes our Chief Financial Officer) in excess of $1 million will generally not be deductible unless it qualifies for
transition relief applicable to certain arrangements in place as of November 2, 2017. We seek to maintain flexibility in compensating our executives in a
manner designed to promote our corporate goals and, therefore, while we are mindful of the benefit of the full

87

 
deductibility of compensation, our Compensation Committee has not adopted a policy requiring that any or all compensation to be deductible. Our
Compensation Committee may authorize compensation payments that are not fully tax deductible if we believe that such payments are appropriate to
attract and retain executive talent or meet other business objectives.

Role of Executives in Executive Compensation Decisions

The Board and our Compensation Committee generally seek input from our Chief Executive Officer, Dr. Ji, when discussing the performance of,

and compensation levels for, executives other than himself. The Compensation Committee also works with Dr. Ji and our Chief Financial Officer to
evaluate the financial, accounting, tax and retention implications of our various compensation programs. Neither Dr. Ji nor any of our other executives
participate in deliberations relating to his compensation.

Compensation Risk Management

We have considered the risk associated with our compensation policies and practices for all employees, and we believe we have designed our
compensation policies and practices in a manner that does not create incentives that could lead to excessive risk taking that would have a material adverse
effect on us for the following reasons:

•

•

We structure our compensation to consist of base salary, variable pay, equity-based pay and benefits. The base portion of compensation is
designed to provide a steady income regardless of our stock price performance so that executives do not feel pressured to focus exclusively
on stock price performance to the detriment of other important business measures. Our variable pay and equity-based pay programs are
designed to reward both short- and long-term corporate performance. For short-term performance, our variable pay programs are designed to
motivate employees to achieve overall goals. For long-term performance, our stock option awards generally vest over four years and are only
valuable if our stock price increases over time. We believe that these variable elements of compensation are a sufficient percentage of overall
compensation to motivate executives to produce superior short- and long-term corporate results, while the fixed element is also sufficiently
high that the executives are not encouraged to take unnecessary or excessive risks in doing so.

Our bonus program has been structured around attainment of overall corporate goals for the past several years and we have seen no evidence
that it encourages unnecessary or excessive risk taking.

The following table provides certain summary information concerning compensation awarded to, earned by or paid to each person who served as
our principal executive officer at any time during fiscal year 2020 and each person who served as our principal financial officer at any time during fiscal
year 2020 (collectively, the “named executive officers”). We did not have any other executive officers during fiscal year 2020.

Does not include for 2020 the amount of any annual bonuses that may be awarded to our named executive officers as the Compensation Committee
has not, as of the date of the filing of this Annual Report on Form 10-K, yet determined the annual bonus amounts, if any, that will be awarded our
named executive officers for 2020. See “-Elements of Compensation-Variable Pay-2020 Bonuses” above for a discussion of the target bonus
amounts for each named executive officer for fiscal year 2020. We expect the Compensation Committee to assess 2020 performance and determine
the 2020 annual bonus awards for our executive officers in the second half of 2021. Dr. Ji may also be entitled to receive a bonus from Scilex
Holding Company in connection with his role as its Executive Chairperson; however, the amount of any such bonus has not yet been determined.
Once such annual bonus amounts, if any, have been determined, we will, in accordance with Securities and Exchange Commission rules and
regulations, file a Current Report on Form 8-K or otherwise disclose the 2020 annual bonus amounts within four business days after the
Compensation Committee has assessed 2020 performance and determined the 2020 annual bonus awards for our named executive officers.

These amounts represent the aggregate grant date fair value of awards for grants of options to purchase shares of our common stock and, for 2020,
options to purchase shares of Scilex Holding Company, to each named executive officer in the relevant fiscal year, computed in accordance with
FASB ASC Topic 718. The dollar amounts listed do not necessarily reflect the dollar amounts of compensation actually realized or that may be
realized by our named executive officers. For a detailed description of the assumptions used for purposes of determining grant date fair value, see
Note 10 of the accompanying notes to the consolidated financial statements in this Annual Report on Form 10-K. These amounts represent the
aggregate grant date fair value of awards for grants of options and warrants to each named executive officer in the relevant fiscal year, computed in
accordance with FASB ASC Topic 718.

Comprised of payments for executive disability benefits.

Comprised of $700,000 of salary paid by us and $441,000 of salary payable by Scilex Holding Company for Dr. Ji’s role as its Executive

on October 16, 2020. Dr. Ji has agreed to forego and relinquish his right to receive any of the additional $301,750 of salary payable from Scilex
Holding Company in the event our stockholders do not approve such compensation at our 2021 annual meeting of stockholders.

Includes $6,510,980 of grant date fair value attributable to the option to purchase 7,844,554 shares of common stock of Scilex Holding Company
that Dr. Ji has agreed to forego and relinquish if it is not approved by our stockholders at our 2021 annual meeting of stockholders. Also includes
$150,317,148 of grant date fair value attributable to the CEO Performance Award, which was approved by our stockholders at our 2020 Annual

The amounts shown in this column do not reflect dollar amounts actually received by our named executive officers. Instead, these amounts
represent the aggregate grant date fair value of the stock option awards determined in accordance with FASB ASC Topic 718. The valuation
assumptions used in determining the amounts are described in Note 10 of the accompanying notes to the consolidated financial statements in
this Annual Report on Form 10-K. Our named executive officers will only realize compensation to the extent the trading price of our common
stock is greater than the exercise price of such stock options on the date the options are exercised.

Reflects the CEO Performance Award, which is intended to compensate Dr. Ji over its 10-year maximum term and will vest only if certain pre-
established market capitalization milestones are achieved, which requires two market capitalization prongs to be met to achieve each milestone:
(1) a six calendar month trailing average (based on trading days); and (2) a 30 calendar day trailing average (based on trading days).  For the
first tranche to vest, Sorrento’s market capitalization has to increase to $5 billion.  For the next two tranches to vest, Sorrento must increase its
market capitalization in additional $2 billion increments, then by increments of $3 billion for the three tranches after that, then by increments of
$4 billion for the next three tranches and a final increment of $5 billion for the final tranche—up to a total market capitalization of $35
billion.  For each tranche that is achieved, Dr. Ji will vest and earn the right to exercise the option for that number of shares of Sorrento
common stock that corresponds to approximately 1% of Sorrento’s total outstanding shares, calculated as of August 6, 2020. The option, to the
extent vested, will be exercisable until August 7, 2030 (ten years from the date of grant). The CEO Performance Award was approved by our
stockholders at the 2020 Annual Meeting of Stockholders held on October 16, 2020.

Represents options granted by our subsidiary, Scilex Holding Company.

Dr. Ji has agreed to forego and relinquish this option award if it is not approved by our stockholders at our 2021 annual meeting of
stockholders.

Represents the fair market value of a share of our common stock, as determined by the Board, on the option’s grant date.

Shares subject to the option vested 25% on each one year anniversary of the Vesting Commencement Date.

Shares subject to the option vest and become exercisable over a four-year period, with 1/4 of the shares vesting on the first anniversary of the
Vesting Commencement Date, and 1/48 of the shares vesting following each one-month period of the participant’s continued employment or service
with the Company thereafter.

62.5% of the shares subject to the option vested over a four-year period, with 1/4 of the shares vesting on the first anniversary of the Vesting
Commencement Date, and 1/48 of the shares vesting following each one-month period of the participant’s continued employment or service with the
Company thereafter. The remaining 37.5% of the shares subject to the option vested upon the consummation of a certain strategic transaction.

Reflects the CEO Performance Award, which is intended to compensate Dr. Ji over its 10-year maximum term and will vest only if certain pre-
established market capitalization milestones are achieved, which requires two market capitalization prongs to be met to achieve each milestone: (1) a
six calendar month trailing average (based on trading days); and (2) a 30 calendar day trailing average (based on trading days).  For the first tranche
to vest, Sorrento’s market capitalization has to increase to $5 billion.  For the next two tranches to vest, Sorrento must increase its market
capitalization in additional $2 billion increments, then by increments of $3 billion for the three tranches after that, then by increments of $4 billion
for the next three tranches and a final increment of $5 billion for the final tranche—up to a total market capitalization of $35 billion.  For each

approximately 1% of Sorrento’s total outstanding shares, calculated as of August 6, 2020. The option, to the extent vested, will be exercisable until
August 7, 2030 (ten years from the date of grant). The CEO Performance Award was approved by our stockholders at the 2020 Annual Meeting of
Stockholders held on October 16, 2020.

NONQUALIFIED DEFERRED COMPENSATION

No pension benefits were paid to any of our named executive officers during fiscal 2020. We do not currently sponsor any non-qualified defined

contribution plans or non-qualified deferred compensation plans.

Employment, Severance, Separation and Change in Control Agreements

Chief Executive Officer Amended and Restated Employment Agreement

On May 9, 2017, we entered into an Amended and Restated Employment Agreement (the “Restated Agreement”) with Dr. Ji. Pursuant to the
Restated Agreement, Dr. Henry Ji will continue to serve as our President and Chief Executive Officer for an initial term of three years commencing on May
9, 2017. Following this initial three year term, the Restated Agreement shall renew automatically for additional 12 month terms unless either we or Dr. Ji
provide written notice of non-renewal at least three months in advance of the expiration of the then-current term. The Restated Agreement supersedes and
replaces a prior employment agreement with Dr. Ji, dated September 21, 2012, as amended on October 18, 2012.

Pursuant to the Restated Agreement, Dr. Ji shall (i) receive an annual base salary (the “Annual Base Salary”) of $600,000, as may be adjusted from

time to time; (ii) be eligible to participate in an annual incentive program, with a target annual bonus incentive equal to 55% of his then-current Annual
Base Salary (the “Annual Bonus”); and (iii) receive employee benefits, paid personal leave and expense reimbursement in accordance with our policies. In
addition, Dr. Ji’s performance will be reviewed by the Board at least annually, and his Annual Base Salary, target Annual Bonus and any other
compensation will be subject to adjustment by the Board, provided that Dr. Ji’s Annual Base Salary and target Annual Bonus may not be adjusted
downward.

Pursuant to the Restated Agreement, we have the right to terminate Dr. Ji’s employment at any time with or without “cause” (as defined in the
Restated Agreement). In addition, Dr. Ji may resign with or without “good reason” (as defined in the Restated Agreement) upon thirty days’ written notice
to us. Under each such circumstance, Dr. Ji will be entitled to receive any accrued but unpaid base salary as of the date of termination or resignation, any
expenses owed to him and any amount accrued and arising from his participation in, or vested benefits accrued under, any employee benefit plans,
programs or arrangements, including any 401(k), profit sharing or pension plan (collectively, the “Termination Payments”).

In the event that Dr. Ji’s employment is terminated by us without “cause” or by our non-renewal of the term of the Restated Agreement, or by Dr. Ji
for “good reason,” in either case outside of a Change of Control Window (as defined below), then, subject to Dr. Ji’s timely execution and non-revocation
of a release in favor of us, Dr. Ji will be entitled to receive the following: (i) the Termination Payments; (ii) an amount equal to his then-current Annual
Base Salary, payable in a lump sum; (iii) an amount equal to his pro-rata then-current target Annual Bonus, payable in a lump sum; (iv) 12 months of health
insurance benefits for Dr. Ji and for his eligible dependents who were covered under our health insurance plans as of the date his employment was
terminated; and (v) one year of accelerated vesting of Dr. Ji’s then-outstanding awards of equity compensation, with performance-criteria deemed satisfied
at target.

If Dr. Ji’s employment is terminated without “cause” or by our non-renewal of the term of the Restated Agreement, or by Dr. Ji for “good reason,” in

either case during the period commencing three months prior to a Change of Control and ending 12 months after a Change of Control (as defined in the
Restated Agreement) (the “Change of Control Window”), then, subject to Dr. Ji’s timely execution and non-revocation of a release in favor of us, Dr. Ji will
be entitled to receive the following: (i) the Termination Payments; (ii) an amount equal to twice his then-current Annual Base Salary, payable in a lump
sum; (iii) an amount equal to twice his pro-rata then-current target Annual Bonus, payable in a lump sum; (iv) 24 months of health insurance benefits for
Dr. Ji and for his eligible dependents who were covered under our health insurance plans as of the date his employment was terminated; and (v) accelerated
vesting of Dr. Ji’s then-outstanding awards of equity compensation, with performance-criteria deemed satisfied target.

The CEO Performance Award does not provide for automatic acceleration of vesting upon a change in control event; however, in the event of a
change of control, the achievement of the market capitalization milestones will be based on our market capitalization determined by the product of the total
number of outstanding shares of our common stock immediately before the change of control multiplied by the per share price (plus the per share value of
any other consideration) received by our stockholders in the change of

93

 
control. Any portion of the  CEO Performance Award that does not vest in accordance with the above will be forfeited automatically as of immediately
prior to the effective time of the change of control and never shall become vested.

Chief Financial Officer Change of Control Severance Agreement

On November 5, 2020, we entered into a Change of Control and Severance Agreement (the “Severance Agreement”) with Mr. Asghar. Pursuant to
the Severance Agreement, if Mr. Asghar’s employment is terminated without “cause” or by Mr. Asghar for “good reason,” in either case during the period
commencing three months prior to a Change of Control (as defined in the Severance Agreement) and ending 12 months after a Change of Control, then,
subject to Mr. Asghar’s timely execution and non-revocation of a release in favor of us, Mr. Asghar will be entitled to receive the following: (i) an amount
equal to his then-current annual base salary, payable in a lump sum; (ii) an amount equal to his then-current target annual bonus, payable in a lump sum;
(iii) 12 months of health insurance benefits for Mr. Asghar and for his eligible dependents who were covered under the Company’s health insurance plans
as of the date his employment was terminated; and (iv) accelerated vesting of Mr. Asghar’s then-outstanding awards of equity compensation, with
performance-criteria, if any, deemed satisfied at target.

POTENTIAL PAYMENTS UPON TERMINATION OR CHANGE IN CONTROL

Other than the provisions of the executive severance benefits to which our named executive officers would be entitled to at December 31, 2020 (the
last trading day of the year) as set forth above, we have no liabilities under termination or change in control conditions. We do not have a formal policy to
determine executive severance benefits. Each executive severance arrangement is negotiated on an individual basis.

The tables below estimate the current value of amounts payable to our named executive officers that were serving as such as of the end of December
31, 2020 in the event that a termination of employment occurred on December 31, 2020 (the last trading day of the year). The closing price of our common
stock, as reported on the Nasdaq Capital Market, was $6.82 on December 31, 2020. The following tables exclude certain benefits, such as accrued vacation,
that are available to all employees generally. The actual amount of payments and benefits that would be provided can only be determined at the time of a
change in control and/or the named executive officer’s qualifying separation from the Company.

Outside Director Compensation Policy

Our outside director compensation policy provides that each non-executive director is entitled to receive a $55,000 annual cash retainer, with the

amount being increased to $78,000 for any Lead Director and $100,000 for any Board chairman. Further, the chairperson of each of our Audit,
Compensation and Transaction Committees receives an additional annual cash retainer of $25,000. Other members of our Audit, Compensation and
Transaction Committees receive an additional cash retainer of $10,000. In addition, each non-executive director will be entitled to receive an annual grant
of a stock option to purchase 100,000 (subject to adjustment for stock splits, reverse stock splits, stock dividends and similar transactions) shares of
common stock, which vests monthly over a period of 12 months from the date of grant, subject to continued service through each vesting date.
Additionally, we reimburse each outside director for reasonable travel expenses related to such director’s attendance at Board and committee meetings.

Other Compensation

We intend to provide benefits and perquisites for our named executive officers at levels comparable to those provided to other executive officers in

our industry. Our Board or any applicable committee thereof, in its discretion, may revise, amend or add to the benefits and perquisites of any named
executive officer as it deems it advisable and in the best interest of the Company and our stockholders.

Compensation Committee Interlocks and Insider Participation

Our Compensation Committee consists of two directors, each of whom is a non-employee director: Mr. Followwill and Dr. Wu. Dr. Wu serves as the
Chairperson of the Compensation Committee. During 2020, neither Mr. Followwill nor Dr. Wu was an officer or employee of ours, was formerly an officer
of ours or had any relationship requiring disclosure by us under Item 404 of Regulation S-K. No interlocking relationship as described in Item 407(e)(4) of
Regulation S-K exists between any of our executive officers or Compensation Committee members, on the one hand, and the executive officers or
compensation committee members of any other entity, on the other hand, nor has any such interlocking relationship existed in the past.

Compensation Committee Report

The Compensation Committee has reviewed and discussed the Compensation Discussion and Analysis required by Item 402(b) of Regulation S-K
of the SEC’s rules and regulations with management and, based on such review and discussions, the Compensation Committee recommended to the Board
of Directors that the Compensation Discussion and Analysis be included in this Annual Report on Form 10-K.

Compensation Committee

Dr. Yue Alexander Wu

Mr. Dorman Followwill

The foregoing Compensation Committee Report shall not be deemed to be “soliciting material,” deemed “filed” with the SEC or subject to the

liabilities of Section 18 of the Exchange Act. Notwithstanding anything to the contrary set forth in any of the Company’s previous filings under the
Securities Act of 1933, as amended, or the Exchange Act that might incorporate by reference future filings, including this Annual Report on Form 10-K, in
whole or in part, the foregoing Compensation Committee Report shall not be incorporated by reference into any such filings.

Pay Ratio Disclosure

As of the date of the filing of this Annual Report on Form 10-K, the pay ratio for Dr. Ji, our Chief Executive Officer, is not calculable. The pay ratio
is not calculable as the Compensation Committee has not, as of the date of the filing of this Annual Report on Form 10-K, yet determined the annual bonus
amounts, if any, that will be awarded our Chief Executive Officer for 2020. We expect the Compensation Committee to assess 2020 performance and
determine the 2020 annual bonus award and actual total compensation for our Chief Executive Officer in the second half of 2021. Once such annual bonus
amount, if any, has been determined, we will, in accordance with Securities and Exchange Commission rules and regulations, file a Current Report on Form
8-K or otherwise disclose the pay ratio within four business days after the Compensation Committee has assessed 2020 performance and determined the
2020 annual bonus awards and actual total compensation for our Chief Executive Officer.

Security Ownership of Certain Beneficial Owners and Management and Related Stockholder Matters.

The following table sets forth information as of January 31, 2021, with respect to the beneficial ownership of shares of our common stock by:

•

•

•

•

each person or group known to us to be the beneficial owner of more than five percent of our common stock;

each of our directors;

each of our named executive officers; and

all of our current directors and executive officers as a group.

This table is based upon information supplied by officers, directors and principal stockholders and a review of Schedules 13D and 13G, if any, filed

with the SEC. Other than as set forth below, we are not aware of any other beneficial owner of more than five percent of our common stock as of January
31, 2021. Except as indicated by the footnotes below, we believe, based on the information furnished to us, that the persons and entities named in the table
below have sole voting and investment power with respect to all shares of common stock that they beneficially own, subject to applicable community
property laws.

Applicable percentage ownership is based on 279,518,736 shares of common stock outstanding as of January 31, 2021, adjusted as required by rules

promulgated by the SEC. These rules generally attribute beneficial ownership of securities to persons who possess sole or shared voting power or
investment power with respect to those securities. In addition, the rules include shares of common stock issuable pursuant to the exercise of stock options
and warrants that are either immediately exercisable or exercisable on or before April 1, 2021, which is 60 days after January 31, 2021. These shares are
deemed to be outstanding and beneficially owned by the person holding those options for the purpose of computing the percentage ownership of that
person, but they are not treated as outstanding for the purpose of computing the percentage ownership of any other person.

Unless otherwise noted below, the address of each beneficial owner listed in the table is c/o Sorrento Therapeutics, Inc., 4955 Directors Place, San

Diego, California 92121.

Item 13.

Certain Relationships and Related Transactions, and Director Independence.

Review, Approval or Ratification of Transactions with Related Persons

The Board conducts an appropriate review of and oversees all related party transactions on a continuing basis and reviews potential conflict of

interest situations where appropriate. The Board has not adopted formal standards to apply when it reviews, approves or ratifies any related party
transaction. However, the Board has followed the following standards: (i) all related party transactions must be fair and reasonable and on terms
comparable to those reasonably expected to be agreed to with independent third parties for the same goods and/or services at the time they are authorized
by the Board and (ii) all related party transactions should be authorized, approved or ratified by the affirmative vote of a majority of the directors who have
no interest, either directly or indirectly, in any such related party transaction.

Transactions with Related Persons

The following is a description of transactions or series of transactions since January 1, 2020, or any currently proposed transaction, to which we

have been a party, in which the amount involved in the transaction or series of transactions exceeds $120,000 and in which any of our directors, executive
officers or persons who we know held more than five percent of any class of our capital stock, including their immediate family members, had or will have

Pulsar Therapeutics, Inc. License Agreement

On May 13, 2020, we entered into a license agreement with Pulsar Therapeutics, Inc. (“Pulsar”), pursuant to which we licensed Pulsar’s

nanoparticle technology for vaccine and antibody uses in exchange for a cash payment, certain royalties of net sales, a sublicense fee and an investment by
the Company in Pulsar through the transfer of 1.0 million shares of our common stock in exchange for a 5.0% equity interest in Pulsar. As of the date of the
investment, Henry Ji, Ph.D., a member of our Board and our Chief Executive Officer and President, was a director and chairperson of the board of directors
of Pulsar and owned approximately 45.0% of Pulsar’s outstanding shares, and Jaisim Shah, a member of our Board, owned approximately 5.0% of Pulsar’s
outstanding shares.

Cytimm Therapeutics, Inc. Equity Interest

On May 15, 2020, we acquired a 50% equity interest in Cytimm Therapeutics, Inc. (“Cytimm”) in exchange for an investment of $2.5 million by the

Company. As of the date of the acquisition, Henry Ji, Ph.D., a member of our Board and our Chief Executive Officer and President, was a director, the
chairperson of the board of directors and a stockholder of Cytimm.

Semnur Pharmaceuticals, Inc. Acquisition

On March 18, 2019, we, for limited purposes, entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Semnur

Pharmaceuticals, Inc. Scilex Holding Company (“Scilex Holding"), Sigma Merger Sub, Inc., the prior wholly owned subsidiary of Scilex Holding (“Merger
Sub”), and Fortis Advisors LLC, solely as representative of the holders of Semnur equity (the “Equityholders’ Representative”). Pursuant to the Merger
Agreement, Merger Sub merged with and into Semnur (the “Merger”), with Semnur surviving as a wholly owned subsidiary of Scilex Holding and thereby
Scilex Holding acquired Semnur’s SEMDEXATM (SP-102) technology for consideration valued at approximately $70.0 million, excluding contingent
consideration, transaction costs of $3.1 million and liabilities assumed of $4.2 million, which was allocated based on the relative fair value of the assets
acquired. The $70.0 million of consideration consisted of approximately $15.0 million in cash and shares of Scilex Holding valued at approximately $55.0
million (the “Stock Consideration”). Following the issuance of the Stock Consideration, the Company’s ownership in Scilex Holding was diluted to
approximately 58% of Scilex Holding’s issued and outstanding capital stock.

Pursuant to the Merger Agreement, and upon the terms and subject to the conditions contained therein, Scilex Holding also agreed to pay the
Semnur Equityholders up to $280.0 million in aggregate contingent cash consideration based on the achievement of certain milestones, which is comprised
of a $40.0 million payment that will be due upon obtaining the first approval of a New Drug Application of a Semnur product by the U.S. Food and Drug
Administration (the “FDA”) and additional payments that will be due upon the achievement of certain amounts of net sales of Semnur products as follows:
(a) a $20.0 million payment upon the achievement of $100.0 million in cumulative net sales of a Semnur product, (b) a $20.0 million payment upon the
achievement of $250.0 million in cumulative net sales of a Semnur product, (c) a $50.0 million payment upon the achievement of $500.0 million in
cumulative net sales of a Semnur product, and (d) a $150.0 million payment upon the achievement of $750.0 million in cumulative net sales of a Semnur
product.

In March 2019, we also entered into an Exchange and Registration Rights Agreement (the “Exchange Agreement”) with the Semnur Equityholders.

Pursuant to the Exchange Agreement, if within 18 months of the closing of the Merger, 100% of the outstanding equity of Scilex Holding had not been
acquired by a third party or Scilex Holding had not entered into a definitive agreement with respect to, or otherwise consummated, a firmly underwritten
offering of Scilex Holding’s capital stock that meets certain requirements and includes the Stock Consideration, then the Semnur Equityholders could
collectively elect to exchange, during the 60-day period commencing the date that is the 18 month anniversary of the closing of the Merger, the Stock
Consideration for shares of our common stock with a value of $55.0 million (the “Semnur Share Exchange”) based on a price per share of our common
stock equal to the greater of (a) the 30-day trailing volume weighted average price of one share of our common stock as reported on the Nasdaq Capital
Market as of the consummation of the Semnur Share Exchange and (b) $5.55 (subject to adjustment for any stock dividend, stock split, stock combination,
reclassification or similar transaction) (the “Exchange Price”). On September 28, 2020, we entered into an amendment to the Exchange Agreement to,
among other things, provide that if we received notice from the Semnur Equityholders that they will proceed with the Semnur Share Exchange (the
“Exchange Notice”), we could, in our sole discretion, elect, within seven days of receipt of the Exchange Notice, to exchange all the Stock Consideration
and the rights to receive cash from Scilex Holding held by the Semnur Equityholders for an amount in cash equal to $55.0 million, in lieu of issuing $55.0
million of shares of our common stock at the Exchange Price. On September 28, 2020, the Semnur Equityholders delivered the Exchange Notice to us. On
October 5, 2020, we notified the Semnur Equityholders of our election to pay cash, and paid $55.0 million in cash to the Semnur Equityholders and
effectuated the Semnur Share Exchange on October 9, 2020.

Jaisim Shah, a member of our Board of Directors, was Semnur’s Chief Executive Officer, a member of its Board of Directors and a stockholder of

Semnur prior to the acquisition transaction.

Mahendra Shah Assignment Agreement

Semnur is party to an Assignment Agreement with Shah Investor LP, pursuant to which Shah Investor LP assigned certain intellectual property to

Semnur and Semnur agreed to pay Shah Investor LP a contingent quarterly royalty in the low-single digits based on quarterly net sales of any
pharmaceutical formulations for local delivery of steroids by injection developed using such intellectual property, which would include SEMDEXA.
Mahendra Shah, Ph.D., who served on the board of directors of Scilex Holding from March 2019 to October 2020, is the managing partner of Shah
Investor LP.

ITOCHU Product Development Agreement

As of December 31, 2020, approximately 14.7% of the outstanding capital stock of Scilex Holding represented a noncontrolling interest that was
held by ITOCHU CHEMICAL FRONTIER Corporation. Scilex Pharma has entered into a product development agreement with ITOCHU CHEMICAL
FRONTIER Corporation, which serves as the sole manufacturer and supplier to Scilex Pharma for ZTlido® (lidocaine topical system 1.8%). During the

Oaktree Term Loan Agreement

On November 7, 2018, we and certain of our domestic subsidiaries (the “Guarantors”) entered into that certain Term Loan Agreement, dated as of

November 7, 2018, by and among the Company, the Guarantors, certain funds affiliated with Oaktree Capital Management, L.P. (“Oaktree” and such funds,
the “Lenders”) and the Oaktree Fund Administration, LLC, as administrative and collateral agent (the “Agent”), as administrative and collateral agent (the
“Original Loan Agreement”), for an initial term loan of $100.0 million on November 7, 2018 (the “Initial Loan”) and a second tranche of $50.0 million,
subject to the achievement of certain commercial and financial milestones between August 7, 2019 and November 7, 2019 and the satisfaction of certain
customary conditions (the “Conditional Loan”). In connection with the Original Loan Agreement, we and the Guarantors entered into a Collateral
Agreement with the Agent (the “Collateral Agreement”). The Collateral Agreement provided that the Initial Loan and the Conditional Loan were secured
by substantially all of our and the Guarantors’ assets and a pledge of 100% of the equity interests in other entities that each of us and the Guarantors held
(subject to certain exceptions and other than equity interests held by us or a Guarantor in certain foreign subsidiaries, which is limited to 65% of such
voting equity interests).

In connection with the Original Loan Agreement, on November 7, 2018, we issued to the Lenders warrants to purchase 6,288,985 shares of the

Company’s common stock (the “Initial Warrants”). The Initial Warrants have an exercise price per share of $3.28, subject to adjustment for stock splits,
reverse stock splits, stock dividends and similar transactions, are exercisable from May 7, 2019 through May 7, 2029 and are exercisable solely on a cash
basis, unless there is not an effective registration statement covering the resale of the shares issuable upon exercise of the Initial Warrants, in which case the
Initial Warrants shall also be exercisable on a cashless exercise basis.

On May 3, 2019, we, the Guarantors and the Lenders and the Agent entered into an amendment (the “First Amendment” and the Original Loan

Agreement, as amended by the First Amendment the “Loan Agreement”). Under the terms of the First Amendment, among other things, on May 3, 2019,
the Lenders loaned to us $20.0 million of the Conditional Loan in the form an additional term loan of $20.0 million on May 3, 2019 (the “Early Conditional
Loan”, and together, with the Initial Loan, the “Term Loans”), notwithstanding that the commercial and financial milestones had not occurred. The Initial
Loan was set to mature on November 7, 2023. The Early Conditional Loan was set to mature on May 3, 2020. The Term Loans may be prepaid by us, in
whole or in part at any time, subject to a prepayment fee. Upon any prepayment or repayment of all or a portion of the Term Loans, we had agreed to pay
the Lenders an exit fee equal to 1.25% of the principal amount paid or prepaid amounting to approximately $1.5 million. The Loan Agreement provided
that, in the event of an optional prepayment of all or any portion of the Term Loans prior to November 7, 2021, we would be obligated to pay a prepayment
fee in an amount equal to the amount of interest that would have been paid on the principal amount of the Term Loans being prepaid for the period from
and including the date of such prepayment to, but excluding, November 7, 2021, based on the interest rate in effect on the date of any such prepayment (the
“Make-Whole Payment”), plus 3% of the principal amount of the Term Loans being so prepaid.

In connection with the First Amendment, on May 3, 2019, we issued to the Lenders warrants to purchase an aggregate of 1,333,304 shares of our
common stock (the “2019 Warrants”). The 2019 Warrants have an exercise price per share of $3.94, subject to adjustment for stock splits, reverse stock
splits, stock dividends and similar transactions, are exercisable from November 3, 2019 through November 3, 2029 and are exercisable solely on a cash
basis, unless there is not an effective registration statement covering the resale of the shares issuable upon exercise of the 2019 Warrants, in which case the
2019 Warrants shall also be exercisable on a cashless exercise basis.

101

 
We paid Oaktree an annual fee of $100,000 for certain advisory services provided to our Board and an annual fee of $100,000 for certain advisory

services provided to the Board of Directors of Scilex Holding Company.

On December 6, 2019, we, the Guarantors, the Lenders and the Agent entered into an amendment (the “Second Amendment”) to the Loan
Agreement. Under the terms of the Second Amendment, the Lenders agreed that, in the event of an optional prepayment of all or any portion of the Term
Loans on or prior to March 31, 2020, the prepayment fee would be equal to 3% of the principal amount of the Term Loans being prepaid, and we would not
be required to pay any Make-Whole Payment. Pursuant to the Second Amendment, we also agreed to certain financial milestones and to fund and maintain,
in a blocked liquidity account, an amount equal to (i) $2.5 million, or (ii) $20.0 million upon the achievement by us of certain financial milestones;
provided, that the amount required to be maintained in the blocked liquidity account was $10.0 million if we made an optional prepayment of at least $50.0
million in principal amount of the Term Loans on or prior to March 31, 2020.

In connection with the Second Amendment, on December 6, 2019, we paid the Lenders certain fees of $1.2 million in the aggregate and issued to

the Lenders warrants to purchase an aggregate of 2,000,000 shares of the Company’s common stock (the “Warrants”). The Warrants have an exercise price
per share of $3.26, subject to adjustment for stock splits, reverse stock splits, stock dividends and similar transactions, will be exercisable from June 6,
2020 through June 6, 2030 and will be exercisable solely on a cash basis, unless there is not an effective registration statement covering the resale of the
shares issuable upon exercise of the Warrants (the “Warrant Shares”), in which case the Warrants shall also be exercisable on a cashless exercise basis.

In connection with the Second Amendment, on December 6, 2019, we and the Lenders entered into an amendment (the “RRA Amendment” and,
together with the Amendment and the Warrants, the “Transaction Documents”) to that certain Registration Rights Agreement, dated as of November 7,
2018, as amended by that certain Amendment No. 1 to the Registration Rights Agreement, dated as of May 3, 2019, by and among us and the persons party
thereto. Under the terms of the RRA Amendment, we agreed to file one or more registration statements with the SEC for the purpose of registering for
resale the Warrant Shares by no later than the 45th day following the issuance of the Warrants.

In connection with the Second Amendment, on December 6, 2019, we and Oaktree entered into a letter agreement (the “Letter Agreement”)

pursuant to which we agreed that our Board would increase the number of members of our Board and, subject to the satisfaction of certain conditions,
appoint Mr. Edgar Lee as a member of our Board. We also agreed that our Board would nominate Mr. Lee as a director at the 2020 annual meeting of our
stockholders and at each subsequent annual meeting during the term of the Letter Agreement. In the event that Mr. Lee resigned as a director or otherwise
refused or was unable to serve as a director during the term of the Letter Agreement, Oaktree could designate a replacement director who would be
independent of Oaktree, considered an independent director under the listing rules of The Nasdaq Stock Market LLC, is mutually agreed upon in writing by
us and Oaktree and had a comparable amount of business experience to Mr. Lee. The Letter Agreement provided that it would terminate if, at any time, the
aggregate principal amount of the Term Loans held by funds associated with Oaktree is $70.0 million or less. Mr. Lee served on the Board from December
2019 to October 2020.

Mr. Lee was a Managing Director at Oaktree, which is the manager of each of the Lenders, during each of the above transactions. In addition,
Oaktree is the parent of OCM Investments LLC, which is the investment manager of each of the Lenders. Mr. Lee was the Chairman of the Board of
Directors, Chief Executive Officer and Chief Investment Officer of Oaktree Strategic Income II, Inc., which is one of the Lenders, during each of the above
transactions. Mr. Lee was the Chief Executive Officer and Chief Investment Officer for Oaktree Specialty Lending Corporation, which is the sole owner
and managing member of OCSL SRNE, LLC, which is one of the Lenders, during each of the above transactions.

On June 12, 2020, we paid off all obligations owing under, and terminated, the Loan Agreement. Pursuant to the Loan Agreement, upon the

prepayment of the amounts outstanding under the Loan Agreement, we paid a prepayment fee in an amount equal to 5% of the principal amount of the
Term Loans prepaid, plus an exit fee in an amount equal to 1.25% of the principal amount of the Term Loans prepaid. The security interests and liens
granted in connection with the Loan Agreement were terminated in connection with our discharge of indebtedness thereunder. In addition, the Letter
Agreement, and the rights of Oaktree thereunder, terminated in connection with our prepayment of the amounts outstanding under the Loan Agreement.

Indemnification Agreements with Directors and Executive Officers

We have entered into indemnity agreements with certain directors, officers and other key employees of ours under which we agreed to indemnify
those individuals under the circumstances and to the extent provided for in the agreements, for expenses, damages, judgments, fines, settlements and any
other amounts they may be required to pay in actions, suits or proceedings which they are or may be made a party or threatened to be made a party by
reason of their position as a director, officer or other agent of ours, and otherwise to the fullest extent permitted under Delaware law and our Bylaws. We
also have an insurance policy covering our directors and executive officers with respect to certain liabilities, including liabilities arising under the Securities
Act of 1933, as amended, or

102

 
otherwise. We believe that these provisions and insurance coverage are necessary to attract and retain qualified directors, officers and other key employees.

Board Independence

Our Board is responsible for establishing corporate policies and for our overall performance, although it is not involved in our day-to-day
operations. Our Board consults with our counsel to ensure that our Board’s determinations are consistent with all relevant securities and other laws and
regulations regarding the definition of “independent,” including those set forth in the rules of The Nasdaq Stock Market LLC, as in effect from time to
time. Consistent with these considerations, after review of all relevant transactions or relationships between each director, or any of his or her family
members, us, our senior management and our independent registered public accounting firm, our Board has determined that all of our directors, other than
Dr. Ji, Dr. Janda and Mr. Shah, are independent.

Audit Committee’s Pre-Approval Policies and Procedures

The Audit Committee has adopted a policy for the pre-approval of audit and non-audit services rendered by our independent registered public
accounting firm. The policy generally pre-approves specified services in the defined categories of audit services, audit-related services and tax services up
to specified amounts. Pre-approval may also be given as part of the Audit Committee’s approval of the scope of the engagement of the independent auditors
or on an individual explicit case-by-case basis before the independent registered public accounting firm are engaged to provide each service. The pre-
approval of services may be delegated to one or more of the Audit Committee members, but the decision must be reported to the full Audit Committee at
its next scheduled meeting. By the adoption of this policy, the Audit Committee has delegated the authority to pre-approve services to the Chairperson of
the Audit Committee, subject to certain limitations.

The Audit Committee has determined that the rendering of services by Ernst & Young LLP other than audit services is compatible with maintaining

the principal accounting firm’s independence.

Report of Independent Registered Public Accounting Firm

To the stockholders and the Board of Directors of Sorrento Therapeutics, Inc.

Opinion on Internal Control over Financial Reporting

We have audited Sorrento Therapeutics, Inc.’s internal control over financial reporting as of December 31, 2020, based on criteria established in Internal
Control—Integrated  Framework  issued  by  the  Committee  of  Sponsoring  Organizations  of  the  Treadway  Commission  (2013  framework)  (the  COSO
criteria). In our opinion, Sorrento Therapeutics, Inc. (the Company) maintained, in all material respects, effective internal control over financial reporting as
of December 31, 2020, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated
balance sheet of Sorrento Therapeutics, Inc. as of December 31, 2020, the related consolidated statements of operations, comprehensive loss, stockholders’
equity  and  cash  flows  for  the  year  ended  December  31,  2020,  and  the  related  notes  and  our  report  dated  February  19,  2021  expressed  an  unqualified
opinion thereon.

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.

Report of Independent Registered Public Accounting Firm

To the Stockholders and the Board of Directors of Sorrento Therapeutics, Inc.

Opinion on the Financial Statements

We  have  audited  the  accompanying  consolidated  balance  sheet  of  Sorrento  Therapeutics,  Inc.  (the  Company)  as  of  December  31,  2020,  the  related
consolidated  statements  of  operations,  comprehensive  loss,  stockholders’  equity  and  cash  flows  for  the  year  ended  December  31,  2020,  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 financial position of the Company at December 31, 2020, and the results of its operations and its cash flows for the year ended December 31,
2020, in conformity with U.S. generally accepted accounting principles.

We also have 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 issued by the
Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) and our report dated February 19, 2021 expressed an unqualified
opinion thereon.

The Company's Ability to Continue as a Going Concern
The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in
Note 2 to the consolidated financial statements, the Company has suffered recurring losses from operations, has a working capital deficiency, and has stated
that  substantial  doubt  exists  about  the  Company’s  ability  to  continue  as  a  going  concern.  Management's  evaluation  of  the  events  and  conditions  and
management’s plans regarding these matters are also described in Note 2. The consolidated financial statements do not include any adjustments that might
result from the outcome of this uncertainty.
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.

Critical Audit Matters

The  critical  audit  matters  communicated  below  are  matters  arising  from  the  current  period  audit  of  the  financial  statements  that  were  communicated  or
required  to  be  communicated  to  the  audit  committee  and  that:  (1)  relate  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 consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions
on the critical audit matters or on the accounts or disclosures to which they relate.

Description
of the
Matter

into  an 

As  discussed  in  Note  8  to  the  consolidated
in  September  2018,
financial  statements, 
Scilex Pharma issued senior notes due 2026 in
an aggregate principal amount of $224 million.
The carrying value of the Scilex Pharma senior
notes,  as  of  December  31,  2020,  was  $97.2
million.  In  connection  with  the  issuance,
Scilex  Pharma  entered 
indenture
governing  the  notes,  pursuant  to  which  the
Company  agreed  to  guarantee  all  obligations
of  Scilex  Pharma  pertaining  to  the  notes.
Management 
identified  embedded  features
within  the  terms  of  the  arrangement  and
ultimately  concluded  certain  features  required
bifurcation  and  recognition  at  fair  value  as  of
each  balance  sheet  date.  During  2020,  the
Company  amended  the  terms  of  the  indenture
and letter of credit and have accounted for the
amendments  in  accordance  with  the  relevant
authoritative guidance.

Auditing  the  Company’s  accounting  for  these
amendments  of  the  indenture  to  the  Scilex
Pharma  senior  notes  was  challenging  because
of  the  complexity  involved  in  evaluating  the
accounting  for  the  amendments,  including
accounting for changes to previously identified
embedded derivatives.

How We
Addressed
the Matter
in Our
Audit

the  Company’s  debt 

We  evaluated  and  tested  the  design  and
operating  effectiveness  of  internal  controls
over 
amendment
accounting  process,  including  controls  over
management’s  assessment  of  the  terms  of  the
amendments  and 
related  accounting
the 
impact.

Our  substantive  audit  procedures  included,
among  others,  evaluating  and  testing  the
accounting  conclusions 
the

Valuation of derivative liabilities

The  Company’s  derivative  liabilities  were
valued  at  $35.4  million  as  of  December  31,
2020.  The  derivative  liabilities  consisted  of
various embedded features in the Scilex notes
and  in  term  loans.  During  the  year,  the
derivatives associated with the term loans were
extinguished as a result of the settlement of the
term  loans.  As  discussed  in  Note  3  to  the
the  fair
consolidated  financial  statements, 
value of the derivative liabilities was estimated
using  the  discounted  cash  flow  method  under
the income approach, combined with a Monte
Carlo simulation model.

Report of Independent Registered Public Accounting Firm

To the stockholders and the Board of Directors of
Sorrento Therapeutics, Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheet of Sorrento Therapeutics, Inc. and subsidiaries (the "Company") as of December 31, 2019,
the related consolidated statements of operations, comprehensive income (loss), stockholders' equity, and cash flows for the two years in the period ended
December 31, 2019, 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, 2019, and the results of its operations and its cash flows for each of the two
years in the period ended December 31, 2019, in conformity with accounting principles generally accepted in the United States of America.

Change in Accounting Principle

As discussed in Note 1 to the financial statements, effective January 1, 2019, the Company adopted FASB Accounting Standards Update 2016-02, Leases,
using the modified retrospective approach.

Going Concern

The accompanying financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 2 to the
financial statements, the Company’s negative working capital, recurring losses from operations, recurring negative cash flows from operations and
substantial cumulative net losses raise substantial doubt about its ability to continue as a going concern. Management's plans in regard to these matters are
also described in Note 2. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.

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.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Organization and Significant Accounting Policies

Description of Business

Sorrento Therapeutics, Inc. (the “Company”) is a clinical stage, antibody-centric, biopharmaceutical company developing new therapies to treat

cancers and COVID-19. The Company’s multimodal, multipronged approach to fighting cancer is made possible by its extensive immuno-oncology
platforms, including key assets such as fully human antibodies (“G-MAB™ library”), clinical stage immuno-cellular therapies (“CAR-T”, “DAR-T™”),
antibody-drug conjugates (“ADCs”) and clinical stage oncolytic virus (Seprehvir™). The Company is also developing potential antiviral therapies and
vaccines against coronaviruses, including COVI-GUARD™, COVI-AMG™, COVI-SHIELD™, Gene-MAb™, COVI-MSC™ and COVI-DROPS™; and
diagnostic test solutions, including COVI-TRACK™, COVI-STIX™ and COVI-TRACE™. 

The Company’s commitment to life-enhancing therapies for patients is also demonstrated by our effort to advance a first-in-class (TRPV1 agonist)

non-opioid pain management small molecule, resiniferatoxin (“RTX”), and SP-102 (10 mg, dexamethasone sodium phosphate viscous gel)
(SEMDEXA™), a novel, viscous gel formulation of a widely used corticosteroid for epidural injections to treat lumbosacral radicular pain, or sciatica, and
through the commercialization of ZTlido® (lidocaine topical system) 1.8% for the treatment of post-herpetic neuralgia.

Basis of Presentation and Principles of Consolidation

The accompanying consolidated financial statements include the accounts of the Company`s subsidiaries. For consolidated entities where the

Company owns or is exposed to less than 100% of the economics, the Company records net income (loss) attributable to noncontrolling interests in its
consolidated statements of operations equal to the percentage of the economic or ownership interest retained in such entities by the respective
noncontrolling parties. All intercompany balances and transactions have been eliminated in consolidation. The Company operates in two operating and
reportable segments, Sorrento Therapeutics and Scilex.

Use of Estimates

The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America

(“U.S. GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial
statements and the reported amounts of expenses during the reporting period. Management believes that these estimates are reasonable; however, actual
results may differ from these estimates.

Cash and Cash Equivalents

The Company considers all highly liquid investments purchased with original maturities of three months or less to be cash equivalents. Cash and

cash equivalents consist of money market accounts and bank deposits, which are highly liquid and readily tradable. The Company minimizes its credit risk
associated with cash and cash equivalents by periodically evaluating the credit quality of its primary financial institutions. The balance at times may exceed
federally insured limits. The Company has not experienced any losses on such accounts.

Restricted Cash

As of December 31, 2020 there was no restricted cash in the Company`s consolidated balance sheet. Restricted cash in the Company's consolidated
balance sheet as of December 31, 2019 included approximately $45.0 million of restricted cash related to the Scilex Notes in the form of both the Reserve
Account and the Collateral Account (See Note 8). Restricted cash in the Company's consolidated balance sheet as of December 31, 2019 also included
approximately $13.1 million of restricted cash related to the Oaktree Term Loan Agreement in the form of a Reserve Account.

Fair Value of Financial Instruments

The Company follows accounting guidance on fair value measurements for financial instruments measured on a recurring basis, as well as for
certain assets and liabilities that are initially recorded at their estimated fair values. Fair value is defined as the exit price, or the amount that would be
received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The Company
uses the following three-level hierarchy that maximizes the use of observable inputs and minimizes the use of unobservable inputs to value its financial
instruments:

•

•

Level 1: Observable inputs such as unadjusted quoted prices in active markets for identical instruments.

Level 2: Quoted prices for similar instruments that are directly or indirectly observable in the marketplace.

F-12

 
 
 
•

Level 3: Significant unobservable inputs which are supported by little or no market activity and that are financial instruments whose values
are determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which the
determination of fair value requires significant judgment or estimation.

Financial instruments measured at fair value are classified in their entirety based on the lowest level of input that is significant to the fair value

measurement. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires it to make
judgments and consider factors specific to the asset or liability. The use of different assumptions and/or estimation methodologies may have a material
effect on estimated fair values. Accordingly, the fair value estimates disclosed or initial amounts recorded may not be indicative of the amount that the
Company or holders of the instruments could realize in a current market exchange.

The carrying amounts of cash equivalents approximate their fair value based upon quoted market prices. Certain of the Company’s financial

instruments are not measured at fair value on a recurring basis, but are recorded at amounts that approximate their fair value due to their liquid or short-
term nature, such as accounts receivable and payable, and other financial instruments in current assets or current liabilities.

Accounts Receivable, Net

Accounts receivable are presented net of allowances for expected credit losses and consist of trade receivables from sales and services provided to
certain customers, which are generally unsecured. Estimated credit losses related to trade accounts receivable are recorded as general and administrative
expenses and as an allowance for doubtful accounts and accounts receivable, net. The Company reviews reserves and makes adjustments based on
historical experience and known collectability issues and disputes. When internal collection efforts on accounts have been exhausted, the accounts are
written off by reducing the allowance for doubtful accounts. The allowance for doubtful accounts is not material.

Inventory, Net

The Company determines inventory cost on a first-in, first-out basis. The Company reduces the carrying value of inventories to a lower of cost or
net realizable value for those items that are potentially excess, obsolete or slow-moving. The Company considers the need for allowances for excess and
obsolete inventory based upon historical experience, sales trends, and specific categories of inventory and expiration dates for inventory on hand. As of
December 31, 2020, net inventory was $1.8 million and primarily comprised of finished goods. Net inventory as of December 31, 2019 was $3.4 million
and primarily comprised of finished goods.

Property and Equipment

Property and equipment are carried at cost less accumulated depreciation. Depreciation of property and equipment is computed using the straight-
line method over the estimated useful lives of the assets, which are generally three to five years. Leasehold improvements are amortized over the lesser of
the life of the lease or the life of the asset. Repairs and maintenance are charged to expense as incurred.

Acquisitions

The Company accounts for business combinations using the acquisition method of accounting, which requires that assets acquired, including in-

process research and development (“IPR&D”) projects and liabilities assumed be recorded at their fair values as of the acquisition date on the Company`s
consolidated balance sheets. Any excess of purchase price over the fair value of net assets acquired is recorded as goodwill. The determination of estimated
fair value requires the Company to make significant estimates and assumptions. As a result, the Company may record adjustments to the fair values of
assets acquired and liabilities assumed within the measurement period (up to one year from the acquisition date) with the corresponding offset to goodwill.
Transaction costs associated with business combinations are expensed as they are incurred.

When the Company determines net assets acquired do not meet the definition of a business combination under the acquisition method of accounting,

the transaction is accounted for as an acquisition of assets and, therefore, no goodwill is recorded and contingent consideration such as payments upon
achievement of various developmental, regulatory and commercial milestones generally is not recognized at the acquisition date. In an asset acquisition,
up-front payments allocated to IPR&D projects at the acquisition date and subsequent milestone payments are charged to expense in the Company`s
consolidated statements of operations unless there is an alternative future use.

Acquired In-Process Research and Development Expense

The Company has acquired, and may continue to acquire, the rights to develop and commercialize new drug candidates. The up-front payments to

acquire new drug compounds or drug delivery devices, as well as future milestone payments associated with assets

F-13

 
 
that do not meet the definition of a derivative and that are deemed probable to achieve, are immediately expensed as acquired IPR&D, provided that the
drug candidates have not achieved regulatory approval for marketing and, absent obtaining such approval, have no alternative future use. Intangible assets
acquired in a business combination that are used for IPR&D activities are considered indefinite lived until the completion or abandonment of the associated
research and development efforts. Upon commercialization of the relevant research and development project, the Company amortizes the acquired IPR&D
over its estimated useful life. Capitalized IPR&D is reviewed annually for impairment or more frequently as changes in circumstance or the occurrence of
events suggest that the remaining value may not be recoverable.

Goodwill and Other Long-Lived Assets

Goodwill, which has an indefinite useful life, represents the excess of cost over fair value of net assets acquired. Goodwill is reviewed at the
reporting unit level for impairment at least annually during the fourth quarter, or more frequently if events occur indicating the potential for impairment.
During its goodwill impairment review, the Company assesses qualitative factors to determine whether it is more likely than not that the fair value of its
reporting unit is less than its carrying amount, including goodwill. The qualitative factors include, but are not limited to, macroeconomic conditions,
industry and market considerations, and the overall financial performance of the Company. If, after assessing the totality of these qualitative factors, the
Company determines that it is not more likely than not that the fair value of its reporting unit is less than its carrying amount, then no additional assessment
is deemed necessary. Otherwise, the Company performs a quantitative goodwill impairment test. The Company may also elect to bypass the qualitative
assessment in a period and elect to proceed to perform the quantitative goodwill impairment test. The Company performed its annual assessment for
goodwill impairment at the Sorrento Therapeutics and Scilex reporting unit levels in the fourth quarter of 2020, noting no indication of impairment. There
were no triggering events indicating the potential for impairment through December 31, 2020.

The Company evaluates its long-lived and intangible assets with definite lives, such as property and equipment, acquired technology, customer

relationships, patent and license rights, for impairment by considering the expected use of the assets and the effects of obsolescence, demand, anticipated
technological advances, market influences and other economic factors. The factors that drive the estimate of useful life are often uncertain and are reviewed
on a periodic basis or when events occur that warrant review. Recoverability is measured by comparison of the assets’ book value to future net
undiscounted cash flows that the assets are expected to generate. No impairment charges were recorded during the year ended December 31, 2020.

Debt, Including Debt With Detachable Warrants

Detachable warrants are evaluated for the classification of warrants as either equity instruments, derivative liabilities, or liabilities depending on the
specific terms of the warrant agreement. In circumstances in which debt is issued with equity-classified warrants, the proceeds from the issuance of debt are
first allocated to the debt and the warrants at their relative estimated fair values. The portion of the proceeds allocated to the warrants are accounted for as
paid-in capital and a debt discount. The remaining proceeds, as further reduced by discounts created by the bifurcation of embedded derivatives and
beneficial conversion features, are allocated to the debt. The Company accounts for debt as liabilities measured at amortized cost and amortizes the
resulting debt discount from the allocation of proceeds, to interest expense using the effective interest method over the expected term of the debt
instrument. The Company considers whether there are any embedded features in debt instruments that require bifurcation and separate accounting as
derivative financial instruments pursuant to Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 815,
Derivatives and Hedging.

If the amount allocated to the convertible debt results in an effective per share conversion price less than the fair value of the Company’s common

stock on the commitment date, the intrinsic value of this beneficial conversion feature is recorded as a discount to the convertible debt with a corresponding
increase to additional paid in capital. The beneficial conversion feature discount is equal to the difference between the effective conversion price and the
fair value of the Company’s common stock at the commitment date, unless limited by the remaining proceeds allocated to the debt.

The Company may enter financing arrangements, the terms of which involve significant assumptions and estimates, including future net product
sales, in determining interest expense, amortization period of the debt discount, as well as the classification between current and long-term portions. In
estimating future net product sales, the Company assesses prevailing market conditions using various external market data against the Company’s
anticipated sales and planned commercial activities. Consequently, the Company imputes interest on the carrying value of the debt and records interest
expense using an imputed effective interest rate. The Company reassesses the expected payments each reporting period and accounts for any changes
through an adjustment to the effective interest rate on a prospective basis, with a corresponding impact to the classification of the Company’s current and
long-term portions.

Derivative Liabilities

Derivative liabilities are recorded on the Company`s consolidated balance sheets at their fair value on the date of issuance and are revalued on each

balance sheet date until such instruments are settled or expire, with changes in the fair value between reporting periods recorded as other income or
expense.

F-14

 
Investments in Other Entities

The Company holds a portfolio of investments in equity securities. Investments in entities over which the Company has significant influence, but

not a controlling interest, are accounted for using the equity method, with the Company’s share of earnings or losses reported in loss on equity method
investments. The Company’s other equity investments are carried at cost, less impairment, plus or minus changes resulting from observable price changes
in orderly transactions for identical or similar investments.

Research and Development Costs

The Company expenses the cost of research and development as incurred. Research and development expenses are comprised of costs incurred in

performing research and development activities, including clinical trial costs, manufacturing costs for both clinical and preclinical materials as well as other
contracted services, license fees and other external costs. Nonrefundable advance payments for goods and services that will be used in future research and
development activities are expensed when the activity is performed or when the goods have been received, rather than when payment is made, in
accordance with FASB ASC Topic 730, Research and Development.

Income Taxes

The provisions of the FASB ASC Topic 740 “Income Taxes,” addresses the determination of whether tax benefits claimed or expected to be claimed
on a tax return should be recorded in the financial statements. Under ASC Topic 740-10, the Company may recognize the tax benefit from an uncertain tax
position only if it is more likely than not that the tax position will be sustained on examination by taxing authorities, based on the technical merits of the
position. The Company has determined that it has uncertain tax positions.

The Company accounts for income taxes using the asset and liability method to compute the differences between the tax basis of assets and

liabilities and the related financial amounts, using currently enacted tax rates.

The Company has deferred tax assets, which are subject to periodic recoverability assessments. Valuation allowances are established, when
necessary, to reduce deferred tax assets to the amount that more likely than not will be realized. As of December 31, 2020, the Company maintained a full
valuation allowance against its deferred tax assets, with the exception of an amount equal to its deferred tax liabilities that are scheduled to reverse against
the Company's deferred tax assets.

Leases

The Company determines if an arrangement is a lease at inception. Operating lease right-of-use (“ROU”) assets and lease liabilities are recognized

at the commencement date based on the present value of lease payments over the lease term. As the Company`s leases do not provide an implicit rate, it
uses its incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments. The
Company calculates the associated lease liability and corresponding ROU asset upon lease commencement using a discount rate based on a credit-adjusted
secured borrowing rate commensurate with the term of the lease. The operating lease ROU asset also includes any lease payments made and is reduced by
lease incentives. The Company`s lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will
exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term.

Revenue Recognition

The Company`s revenues are generated from product revenues, the sale of customized reagents and other materials, contract manufacturing services,

and other service revenues.

The following table shows revenue disaggregated by product and service type for the years ended December 31, 2020, 2019 and 2018 (in

The Company is obligated to accept from customers the return of products sold that are damaged or do not meet certain specifications. The
Company may authorize the return of products sold in accordance with the terms of its sales contracts and estimates allowances for such amounts at the
time of sale. The Company has not experienced any material sales returns.

The Company does not disclose the value of unsatisfied performance obligations for (i) contracts with an original expected length of one year or less

and (ii) contracts for which it recognizes revenue at the amount to which it has the right to invoice for services performed.

Scilex Product Sales

Revenues from product sales is fully comprised of sales of ZTlido. The Company's performance obligation with respect to sales of ZTlido is

satisfied at a point in time, which transfers control upon delivery of product to the customer. The Company considers control to have transferred upon
delivery because the customer has legal title to the asset, physical possession of the asset has been transferred to the customer, the customer has significant
risks and rewards of ownership of the asset, and the Company has a present right to payment at that time. The Company identified a single performance
obligation. Invoicing typically occurs upon shipment and the length of time between invoicing and when payment is due is not significant. The aggregate
dollar value of unfulfilled orders as of December 31, 2020 was not material. Sales of ZTlido are generated within the United States. Substantially all of the
Company’s product revenue and accounts receivable result from a sole customer.

For product sales, the Company records gross-to-net sales adjustments for government and managed care rebates, chargebacks, wholesaler and

distributor fees, sales returns and prompt payment discounts. Such variable consideration is estimated in the period of the sale and are estimated using a
most likely amount approach based primarily upon provisions included in the Company’s customer contract, customary industry practices and current
government regulations.

Other Product Revenue

Revenues from the sale of materials associated with the Company's research and development arrangements are recognized at a point in time upon

the transfer of control, which is generally upon shipment.

Concortis Biosystems Corporation (“Concortis”)

Contract manufacturing associated with sales of customized reagents for Concortis operations relate to providing synthetic expertise to customers’

synthesis by delivering proprietary cytotoxins, linkers and linker-toxins and ADC service using industry standard toxin and antibodies provided by
customers which are recognized at a point in time upon the transfer of control, which is generally upon shipment given the short contract terms which are
generally three months or less.

Bioserv Corporation (“Bioserv”)

Contract manufacturing services associated with the Company’s Bioserv operations related to finish and fill activities for drug products and reagents

are recognized ratably over the contract term, which reflects the transfer of services to the customer because the manufactured products are highly
customized and do not have an alternative use to the Company. As of December 31, 2020 and 2019, the estimated revenue expected to be recognized for
future performance obligations associated with contract manufacturing services was approximately $3.4 million and $2.2 million, respectively.

Joint Development Agreement

In 2017, the Company entered into a joint development agreement with Celularity Inc. (“Celularity”) whereby the Company agreed to provide

research services to Celularity through June 2018 in exchange for an upfront payment of $5.0 million. The revenue related to the joint development
agreement of $5.0 million was recognized over the length of the service agreement as services were performed. The Company recorded sales and services
revenues under the joint development agreement of $3.3 million for the year ended December 31, 2018. The Company recorded no sales and services
revenues under the joint development agreement during the years ended December 31, 2020 and 2019 as such arrangement is complete.

Other Service Revenue

License fees for the licensing of product rights are recorded as deferred revenue upon receipt of cash and recognized as revenue on a straight-line

basis over the license period, with the exception of license agreements with no remaining performance obligations or undelivered obligations. The
Company applies judgment in determining the timing of revenue recognition related to contracts that include multiple performance obligations. The total
transaction price of the contract is allocated to each performance obligation in an amount based on the estimated relative standalone selling prices of the
promised goods or services underlying each performance

F-16

 
 
obligation. For goods or services for which observable standalone selling prices are not available, the Company develops an estimated standalone selling
price of each performance obligation.

As of December 31, 2020, future performance obligations for license revenues relate to the ImmuneOncia Therapeutics, LLC (“ImmuneOncia”) and

NantCell, Inc. (“NantCell”) license agreements.

The total consideration for the ImmuneOncia license performance obligation, effective September 1, 2016, represented $9.6 million. The estimated
revenue expected to be recognized for future performance obligations, as of December 31, 2020, was approximately $7.5 million. The Company expects to
recognize license revenue of approximately $0.5 million of the remaining performance obligation annually through the remaining term. The Company
applied judgment in estimating the 20-year contract term, analogous to the expected life of the patent, over which revenue is recognized over time given the
ongoing performance obligation related to the Company's participation on a steering committee for the technologies under the agreement.

As of December 31, 2020 and 2019, the NantCell license agreement, effective April 21, 2015, represented $110.0 million of contract liabilities

reflected in long-term deferred revenue. See Note 7 for additional information regarding the remaining performance obligation for the agreement.

In November 2020, the Company was awarded a contract with the Defense Advanced Research Projects Agency (“DARPA Contract”) and co-
funded by the Joint Program Executive Office for Chemical, Biological, Radiological and Nuclear Defense, to develop a rapid countermeasure to COVID-
19 using gene-encoded neutralizing antibodies. The contract provides SmartPharm Therapeutics, Inc. (“SmartPharm”) funding of up to $34.0 million for
the development through Phase II clinical studies of a gene-encoded antibody that could enable rapid protection from and/or treatment of SARS-CoV-2
infection and COVID-19. The Company recognized $0.2 million in grant revenue associated with the DARPA Contract during the year ended December
31, 2020, which is included within other service revenue.

Stock-Based Compensation

The Company estimates the fair value of stock option awards and its Employee Stock Purchase Plan (“ESPP”) on the grant or offering date using the
Black-Scholes option-pricing model. The Black-Scholes option-pricing model requires inputs such as the risk-free interest rate, expected term and expected
volatility.Stock-based compensation expense is recognized on a straight-line basis, net of actual forfeitures in the period.

Comprehensive Loss

Comprehensive loss is primarily comprised of net income (loss) and foreign currency translation adjustments. The Company displays

comprehensive loss and its components in its consolidated statements of comprehensive loss.

Net Income (Loss) per Share

Basic net income (loss) per share is computed by dividing net loss for the period by the weighted average number of shares of common stock

outstanding. Diluted net loss per share reflects the additional dilution from potential issuances of common stock, such as stock issuable pursuant to the
exercise of stock options or the exercise of outstanding warrants. The treasury stock method and the if-converted method are used to calculate the potential
dilutive effect of these common stock equivalents. Potentially dilutive shares are excluded from the computation of diluted net loss per share when their
effect is anti-dilutive. In periods where a net loss is presented, all potentially dilutive securities are anti-dilutive and are excluded from the computation of
diluted net loss per share.

Recent Accounting Pronouncements

In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-13, Financial

Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, to improve financial reporting by requiring timely
recording of credit losses on loans and other financial instruments held by financial institutions and other organizations. The ASU requires the
measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions and reasonable
and supportable forecasts. The ASU was effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years.
The amendments in this update were adopted using a modified retrospective transition method as of January 1, 2020, which had no cumulative impact to
accumulated deficit.

In August 2018, the FASB issued ASU No. 2018-13, Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement,

to improve the effectiveness of the disclosure requirements for fair value measurements. The ASU was effective for fiscal years and interim periods
beginning after December 15, 2019. Amendments on changes in unrealized gains and losses, the range and weighted average of significant unobservable
inputs used to develop Level 3 fair value measurements and the narrative description of measurement uncertainty were applied prospectively as of the
beginning of the fiscal year of adoption with all other amendments being applied retrospectively to all periods presented upon their effective date. The
Company adopted the standard in the first quarter of 2020 with no material impact on the Company’s consolidated financial statements.

In January 2017, the FASB issued ASU No. 2017-04, Simplifying the Test for Goodwill Impairment (Topic 350). This standard eliminates Step 2
from the goodwill impairment test, instead requiring an entity to recognize a goodwill impairment charge for the amount by which the goodwill carrying
amount exceeds the reporting unit’s fair value. This update also eliminated the qualitative assessment requirements for a reporting unit with zero or
negative carrying value. This guidance was effective for interim and annual goodwill impairment tests in fiscal years beginning after December 15, 2019,
with early adoption permitted, and must be applied on a prospective basis. The Company adopted the standard in the first quarter of 2020 with no material
impact on the Company’s consolidated financial statements.

In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. The amendments

in this update simplify the accounting for income taxes by removing certain exceptions to the general principles in Accounting Standards Codification
(“ASC”) Topic 740. The amendments also improve consistent application of and simplify U.S. GAAP for other areas of ASC Topic 740 by clarifying and
amending existing guidance. The amendments in this update are effective for interim and annual periods for the Company beginning after December 15,
2020, with early adoption permitted. The Company has evaluated the changes from the standard update and determined any impacts would be immaterial
on its consolidated financial statements. The Company will adopt the new guidance on January 1, 2021.

2. Liquidity and Going Concern

The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern, which
contemplates the realization of assets and satisfaction of liabilities in the normal course of business. The Company has negative working capital and
recurring losses from operations, recurring negative cash flows from operations and substantial cumulative net losses to date and anticipates that it will
continue to do so for the foreseeable future as it continues to identify and invest in advancing product candidates, as well as expanding corporate
infrastructure.  

The Company has plans in place to obtain sufficient additional fundraising to fulfill its operating and capital requirements for the next 12 months.

The Company’s plans include continuing to fund its operating losses and capital funding needs through public or private equity or debt financings, strategic
collaborations, licensing arrangements, asset sales, government grants or other arrangements. Although management believes such plans, if executed,
should provide the Company sufficient financing to meet its needs, successful completion of such plans is dependent on factors outside of the Company’s
control. As such, management cannot conclude that such plans will be effectively implemented within one year after the date that the financial statements
are issued. As a result, management has concluded that the aforementioned conditions, among others, raise substantial doubt about the Company’s ability to
continue as a going concern within one year after the date the financial statements are issued.

If the Company is unable to raise additional capital in sufficient amounts or on terms acceptable, the Company may have to significantly delay, scale

back or discontinue the development or commercialization of one or more of its product candidates. The Company may also seek collaborators for one or
more of its current or future product candidates at an earlier stage than otherwise would be desirable or on terms that are less favorable than might
otherwise be available. The consolidated financial statements do not reflect any adjustments that might be necessary if the Company is unable to continue
as a going concern.

If the Company raises additional funds by issuing equity securities, substantial dilution to existing stockholders would result. If the Company raises

additional funds by incurring debt financing, the terms of the debt may involve significant cash payment obligations as well as covenants and specific
financial ratios that may restrict the Company’s ability to operate its business.

There were no changes to the fair value of acquisition consideration payable during the year ended December 31, 2020.

During the year ended December 31, 2019, the fair value remeasurement adjustments related to the Company’s acquisitions resulted in a decrease to

the contingent consideration liabilities by $0.7 million. The Company also recorded a $10.4 million gain related to the settlement of the acquisition
consideration payable associated with the Virttu acquisition.

During the year ended December 31, 2018, the fair value remeasurement adjustments related to the Company’s acquisitions resulted in an increase

to the contingent consideration liabilities by $9.6 million. The Company recorded $51.9 million in settlements of contingent consideration primarily related
to such liabilities, which included the settlements of Scilex Pharmaceuticals Inc. (“Scilex Pharma”) and BDL liabilities for $38.2 million and $2.3 million,
respectively, and the $11.3 million partial settlement of the Virttu financing milestone in common stock of the Company.

Derivative liabilities

The Company recorded a gain on derivative liabilities of $6.6 million and a loss on derivative liabilities of $36.8 million for the years ended
December 31, 2020 and 2019, respectively, which related to the compound derivative liabilities associated with the Term Loans and the Scilex Notes (as
defined in Note 8). The compound derivative liabilities consist of the fair value of various embedded features as further described in Note 8. The fair value
of the derivative liabilities associated with the Scilex Notes was estimated using the discounted cash flow method under the income approach combined
with a Monte Carlo simulation model. This involves significant Level 3 inputs and assumptions. The key assumptions for the Scilex Notes for the year
ended December 31, 2020 included a 7% risk-adjusted net sales forecast, an effective debt yield of 15% and an estimated probability of 100% of not
obtaining marketing approval before March 31, 2021. The key assumptions for the Scilex Notes for the year ended December 31, 2019 included an 8% risk
adjusted net sales forecast, an effective debt yield of 19.7% and estimated probabilities of 55% and 100% of not obtaining marketing approval before July
1, 2023 and March 31, 2021, respectively, and an estimated high probability of a Scilex Holding IPO that satisfies certain valuation thresholds.

Significant Level 3 inputs and assumptions for derivative liabilities associated with the Term Loans primarily included the estimated probabilities of

satisfying certain commercial and financial milestones estimated using a with and without discounted cash flow approach. As explained further in Note 8,
the Term Loans, which include the Early Conditional Loan, were paid in full as of December 31, 2020 and the associated derivative liabilities were
relieved.

During the year ended December 31, 2019, the Company recorded a derivative liability and corresponding debt discount of approximately
$7.0 million, which was attributed to a contingent acceleration feature related to the Early Conditional Loan. The debt discount was amortized over the
remaining term of the Term Loans and was recorded as interest expense in the consolidated statement of operations. Additionally, the Company recorded a
mark-to-market loss on derivative liabilities related to the contingent acceleration feature of the Early Conditional Loan of $1.8 million for the year ended
December 31, 2019. The Company also recorded a loss on derivative liabilities of $4.3 million during 2019 associated with the 2019 Warrants (as defined
in Note 8) for the year ended December 31, 2019.

5. Investments

The Company’s equity method investments include an ownership interest in Immunotherapy NANTibody, LLC (“NANTibody”),

NantCancerStemCell, LLC (“NantStem”) and ImmuneOncia Therapeutics, LLC, among others. The Company’s other equity investments include an
ownership interest in ImmunityBio, Inc., NantBioScience, Inc. (“NantBioScience”), and Celularity Inc.

During the year ended December 31, 2020, the Company recorded an impairment loss of approximately $3.8 million related to an equity method

investment for which the Company determined the investment’s value is no longer supportable. The loss is included within loss on equity method
investments in the Company’s consolidated statement of operations.

NANTibody

The Company’s investment in NANTibody is reported in equity method investments on its consolidated balance sheets and its share of

NANTibody’s income or loss is recorded in loss on equity method investments on its consolidated statement of operations. The Company continues to hold
40% of the outstanding equity of NANTibody and NantCell holds the remaining 60%. The carrying value of the Company’s investment in NANTibody was
approximately $0.5 million and $2.5 million as of December 31, 2020 and 2019, respectively.

NANTibody recorded net loss of $0.1 million, $2.4 million and $0.7 million for the twelve months ended September 30, 2020, 2019 and 2018,
respectively. As of September 30, 2020, NANTibody had $4.9 million in current assets, $3.5 million in current liabilities, $0.2 million in noncurrent assets
and no noncurrent liabilities. As of September 30, 2019, NANTibody had $7.3 million in current assets, $1.0 million in current liabilities, $0.2 in
noncurrent assets and no noncurrent liabilities.

The financial statements of NANTibody are not received sufficiently timely for the Company to record its portion of earnings or loss in the current

financial statements and therefore the Company reports its portion of earnings or loss on a one quarter lag.  

NantStem

The Company’s investment in NantStem is reported in equity method investments on its consolidated balance sheets and its share of NantStem’s

income or loss is recorded in loss on equity method investments on its consolidated statement of operations. The Company is accounting for its interest in
NantStem as an equity method investment, due to the significant influence the Company has over the operations of NantStem through its board
representation and 20% voting interest. The carrying value of the Company’s investment in NantStem was approximately $18.1 million and $17.9 million
as of December 31, 2020 and 2019, respectively.

NantStem recorded a net gain of $0.1 million and net loss of $0.9 million for the twelve months ended September 30, 2020 and 2019, respectively.

As of September 30, 2020, NantStem had $80.0 million in current assets, no current liabilities and $1.7 million noncurrent assets and no noncurrent
liabilities. As of September 30, 2019, NantStem had $75.9 million in current assets, $0.2 million in current liabilities, $4.7 million in noncurrent assets and
no noncurrent liabilities. A loss related to other-than-temporary impairment of $0.5 million was recognized for the equity investment in NantStem for the
year ended December 31, 2018.

6. Goodwill and Intangible Assets

The Company had goodwill of $43.6 million as of December 31, 2020, which increased by $5.3 million as compared to $38.3 million as of

December 31, 2019 due to the Company’s acquisition of SmartPharm. The Company performed a qualitative test for goodwill impairment by segment
during the fourth quarter of 2020. No goodwill impairment was recognized for the years ended December 31, 2020, 2019 and 2018.

Commencing January 1, 2019, the Company re-segmented its business into two new operating segments: the Sorrento Therapeutics segment and the

Scilex segment. These segments are the Company’s reporting units and are the level at which the Company conducts its goodwill impairment evaluations.
Goodwill was allocated to the Sorrento Therapeutics and the Scilex operating segments on a relative fair value basis. Goodwill for the Sorrento
Therapeutics segment and Scilex segment was $36.9 million and $6.7 million, respectively, as of December 31, 2020.

On September 1, 2020, the Company completed the acquisition of SmartPharm, a gene-encoded protein therapeutics company developing non-viral

DNA and RNA gene delivery platforms for COVID-19, Influenza and rare diseases with broad potential for application in enhancing antibody-centric
therapeutics. The total base consideration paid to the holders of capital stock of SmartPharm in the acquisition was $19.5 million, which was comprised of
approximately 1.8 million shares of the Company’s common stock.

The purchase price allocation resulted in net identifiable assets of $19.5 million, which includes separate and distinct indefinite lived intangible

assets comprised of acquired in-process research and development of $13.9 million, goodwill of $5.3 million and other net assets of $0.3 million.
Customary tax related matters such as the filing of pre-acquisition tax returns are subject to finalization as of December 31, 2020. Such matters may result
in adjustments to the purchase price allocation. Goodwill largely reflects the synergies expected to be achieved with SmartPharm’s gene delivery platforms
and the assembled workforce. Goodwill is not deductible for tax purposes. Results of operations since the date of acquisition were not material.

2019 Acquisition

Acquisition of Semnur Pharmaceuticals, Inc. (“Semnur”)

On March 18, 2019, the Company entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Semnur Pharmaceuticals, Inc.

(“Semnur”) and Scilex Holding, whereby Semnur became a wholly-owned subsidiary of Scilex Holding (the “Merger”), and thereby Scilex Holding
acquired Semnur’s SEMDEXATM (SP-102) technology for consideration valued at approximately $70.0 million, excluding contingent consideration,
transaction costs of $3.1 million and liabilities assumed of $4.2 million, which was allocated based on the relative fair value of the assets acquired. The
$70.0 million of consideration consisted of approximately $15.0 million in cash and shares of Scilex Holding valued at approximately $55.0 million (the
“Stock Consideration”). Following the issuance of the Stock Consideration, the Company’s ownership in Scilex Holding was diluted to approximately 58%
of Scilex Holding’s issued and outstanding capital stock.

Pursuant to the Merger Agreement, Scilex Holding also agreed to pay the holders of Semnur’s capital stock and options (the “Semnur

Equityholders”) up to $280.0 million in aggregate contingent cash consideration based on the achievement of certain milestones, which is comprised of a
$40.0 million payment that will be due upon obtaining the first approval of a New Drug Application of a Semnur product by the U.S. Food and Drug
Administration (the “FDA”) and additional payments that will be due upon the achievement of certain amounts of net sales of Semnur products as follows:
(a) a $20.0 million payment upon the achievement of $100.0 million in cumulative net sales of a Semnur product, (b) a $20.0 million payment upon the
achievement of $250.0 million in cumulative net sales of a Semnur product, (c) a $50.0 million payment upon the achievement of $500.0 million in
cumulative net sales of a Semnur product, and (d) a $150.0 million payment upon the achievement of $750.0 million in cumulative net sales of a Semnur
product.

In March 2019, the Company also entered into an Exchange and Registration Rights Agreement (the “Exchange Agreement”) with the Semnur

Equityholders. Pursuant to the Exchange Agreement, if within 18 months of the closing of the Merger, 100% of the outstanding equity of Scilex Holding
had not been acquired by a third party or Scilex Holding had not entered into a definitive agreement with respect to, or otherwise consummated, a firmly
underwritten offering of Scilex Holding’s capital stock that meets certain requirements and includes the Stock Consideration, then the Semnur
Equityholders could collectively elect to exchange, during the 60-day period commencing the date that is the 18 month anniversary of the closing of the
Merger, the Stock Consideration for shares of the Company’s common stock with a value of $55.0 million (the “Semnur Share Exchange”) based on a price
per share of the Company’s common stock equal to the greater of (a) the 30-day trailing volume weighted average price of one share of the Company’s
common stock as reported on the Nasdaq Capital Market as of the consummation of the Semnur Share Exchange and (b) $5.55 (subject to adjustment for
any stock dividend, stock split, stock combination, reclassification or similar transaction) (the “Exchange Price”). On September 28, 2020, the Company
entered into an amendment to the Exchange Agreement to, among other things, provide that if the Company received notice from the Semnur
Equityholders that they will proceed with the Semnur Share Exchange (the “Exchange Notice”), the Company could, in its sole discretion, elect, within
seven days of receipt of the Exchange Notice, to exchange all the Stock Consideration and the rights to receive cash from Scilex Holding held by the
Semnur Equityholders for an amount in cash equal to $55.0 million, in lieu of issuing $55.0 million of shares of the Company’s common stock at the
Exchange Price. On September 28, 2020, the Semnur Equityholders delivered the Exchange Notice to the Company. On October 5, 2020, the Company
notified the Semnur Equityholders of its election to pay cash, and paid $55.0 million in cash to the Semnur Equityholders and effectuated the Semnur Share
Exchange on October 9, 2020. Following the completion of the Semnur Share Exchange and as of December 31, 2020, the Company held approximately
82.3% of the outstanding common stock of Scilex Holding. On January 29, 2021, the Company acquired additional shares of Scilex Holding, resulting in
the Company holding approximately 99.9% of the outstanding common stock of Scilex Holding.

The transaction was accounted for as an asset acquisition since substantially all the value of the gross assets was concentrated in a single asset. No
contingent consideration was recorded as of December 31, 2019 and 2020 since the related regulatory approval milestones are not deemed probable until
they actually occur. Approximately $75.3 million was expensed as acquired in-process research and development during the year ended December 31,
2019.

2018 Acquisition

Acquisition of Sofusa®

In July 2018, the Company acquired Kimberly-Clark’s Sofusa® micro-needle drug delivery system platform (the “Sofusa Acquisition”). At the

closing of the Sofusa Acquisition, the Company paid $10.0 million and agreed to pay additional consideration to Kimberly-Clark upon the achievement of
certain regulatory and net sales milestones, as well as a percentage in the low double-digits of any non-royalty amounts received by the Company in
connection with any license, sale or other grant of rights by the Company to develop or commercialize the Sofusa Assets (the “Sofusa Contingent
Consideration”). Under the Sofusa Purchase Agreement, the aggregate amount of the Sofusa Contingent Consideration payable by the Company will not
exceed $300.0 million. The Company also agreed to pay Kimberly-Clark a low single-digit royalty on all net sales with respect to the first five products
developed by the Company or its licensees that utilizes intellectual property included in the Sofusa Assets. The transaction was accounted for as an asset
acquisition since substantially all the value of the gross assets was concentrated in a single asset. No contingent consideration was recorded as of December
31, 2020 since the related regulatory approval milestones are not deemed probable until they actually occur. As a result, $9.5 million was expensed as
acquired in-process research and development and the remaining $0.5 million was recorded primarily to fixed assets.

License Agreements

License Agreement with ACEA Therapeutics, Inc.

In July 2020, the Company entered into a License Agreement (the “ACEA License Agreement”) with ACEA Therapeutics, Inc. (“ACEA”).

Pursuant to the ACEA License Agreement, ACEA granted the Company an exclusive license and right under certain patents and certain know-how and
other intellectual property (“Licensed Know-How”) to fully utilize, exploit and commercialize (i) the Licensed Know-How, (ii) Abivertinib (AC0010), a

achievement of certain commercial sales milestones. The milestone payments may be comprised of cash or any combination of cash and common stock of
the Company, in any case as determined by the

F-24

 
Company so long as no more than 50% of any upfront payment or milestone payment is comprised of common stock. The Company will also pay certain
royalties in the mid-single digit to low-double digit percentages of annual net sales by the Company.

License Agreement with The Trustees of Columbia University in the City of New York

In July 2020, the Company entered into an Exclusive License Agreement (the “Columbia License Agreement”) with The Trustees of Columbia

ten days following the first bona fide commercial sale of a Product to a third-party customer and on an annual basis thereafter. In addition, the Company
agreed to pay Columbia a percentage of certain non-royalty sublicense revenue and other payments received by the Company from its sublicensees as
consideration for the grant of any sublicense, option or similar rights. Pursuant to the Columbia License Agreement, the Company also agreed to pay
certain one-time, development milestone payments to Columbia upon the receipt of certain regulatory approvals or the first commercial sale of certain
Products for diagnostic applications within the Field.

License Agreement with Mayo Foundation

In September 2020, the Company entered into a patent and know-how license agreement (the “Mayo License Agreement”) with Mayo Foundation

for Medical Education and Research (“Mayo”). Pursuant to the Mayo License Agreement, Mayo granted the Company a sublicensable license under certain
of Mayo’s patents, know-how, and materials relating to targeted nanoparticle therapies (“Patent Rights”, “Know-How”, and “Materials”, respectively) to
reproduce, use, commercialize, and exploit related products, processes and services (“Licensed Products”) for the prevention, diagnosis and/or treatment of
human diseases and conditions worldwide.

As consideration for the license under the Mayo License Agreement, the Company paid Mayo an upfront license fee of $9.3 million comprised of

approximately $2.3 million in cash and 996,803 shares of the Company’s common stock, which was expensed as acquired in-process research and
development during the year ended December 31, 2020. The Company also agreed to (i) reimburse Mayo up to $3.4 million for preclinical and clinical
research expenses associated with the Know-How, Patent Rights and Materials arising prior to the entry into the Mayo License Agreement, and (ii)
reimburse Mayo approximately $2.0 million for expenses related to the development and manufacturing of the Materials arising prior to the entry into the
Mayo License Agreement. Such reimbursements were paid and expensed as acquired in-process research and development during the year ended
December 31, 2020.

The Company also agreed to pay Mayo (i) certain milestone payments upon the initiation of certain clinical trials, (ii) certain milestone payments

upon the receipt of certain regulatory approvals, and (iii) certain milestone payments upon the achievement of certain commercial sales milestones. The
Company will also pay certain royalties in the low-single digit to mid-single digit percentages of annual net sales of Licensed Products by the Company
and a share of any sublicense revenue received by the Company from sublicensees.

License Agreement with Personalized Stem Cells, Inc.

In October 2020, the Company entered into a license agreement (the “License Agreement”) with Personalized Stem Cells, Inc. (“PSC”). Pursuant

to the License Agreement, PSC granted the Company an exclusive license and right under certain patents, certain know-how and other intellectual property
to fully utilize, exploit and commercialize certain products and services using allogeneic adipose-derived stem cells for or in respect of human health,
including the diagnosis and treatment and/or cure of any human disease or disorder (excluding commercial sales for the diagnosis, treatment and/or cure of
SARS-CoV-2 or other respiratory diseases in the People’s Republic of China) worldwide (excluding the People’s Republic of China for products directed at
COVID-19 or other respiratory diseases). PSC also agreed to transfer certain cell lines composed of stromal vascular cells, master cell banks and finished
final drug lots (the “Product Materials”) to the Company. The Company agreed to grant PSC rights to use data derived by the Company from a certain
Phase I COVID-19 study for PSC’s own programs that are not competitive with the businesses or activities of the Company, and for PSC to sublicense such
data to third parties for research, development and regulatory purposes.

F-25

 
 
As consideration for the license under the License Agreement, the Company paid PSC an upfront license fee of $3.5 million in cash, which was

expensed as acquired in-process research and development during the year ended December 31, 2020. The Company also agreed to pay PSC (i) a milestone
payment upon the issuance of a regulatory approval, and (ii) certain milestone payments upon PSC’s manufacture and delivery of the Product Materials to
the Company. The Company will also pay royalties in the low-single digit percentages of annual net sales of licensed products and services by the
Company and a share of any sublicense revenue received by the Company from sublicensees.

License Agreement with NantCell

In April 2015, the Company and NantCell entered into a license agreement. Under the terms of the agreement, the Company granted an exclusive
license to NantCell covering patent rights, know-how, and materials related to certain antibodies, ADCs and two CAR-TNK products. NantCell agreed to
pay a royalty not to exceed five percent (5%) to the Company on any net sales of products (as defined) from the assets licensed by the Company to
NantCell. In addition to the future royalties payable under this agreement, NantCell paid an upfront payment of $10.0 million to the Company and issued
10 million shares of NantCell common stock to the Company valued at $100.0 million based on a recent equity sale of NantCell common stock to a third
party. The Company terminated the agreement, effective January 29, 2020, due to NantCell`s material breach of the agreement. The termination and
remedies related to such termination are currently pending in an arbitration before the American Arbitration Association. The Company has therefore
deferred recognition of the upfront payment and the value of the equity interest received until the arbitration is concluded or resolved. The Company’s
ownership interest in NantCell does not provide the Company with control or the ability to exercise significant influence; therefore the $100.0 million
investment is carried at cost in the consolidated balance sheets and evaluated for other-than-temporary impairment on a quarterly basis.

Short-term working capital funding arrangements

In November 2019, the Company entered into short-term working capital funding arrangements (the “Arrangements”) in which the Company
received proceeds of approximately $8.0 million, for a fee of 5% per annum. Additionally, the Company provided security deposits in an aggregate amount
of approximately $8.5 million (RMB 60.0 million). During the fiscal year ended December 31, 2020, the Company repaid $8.0 million of the
Arrangements in full, including fees, which was included in the current portion of debt.

2018 Purchase Agreements and Indenture for Scilex

On September 7, 2018, Scilex Pharma entered into Purchase Agreements (the “2018 Purchase Agreements”) with certain investors (collectively, the
“Scilex Note Purchasers”) and the Company. Pursuant to the 2018 Purchase Agreements, on September 7, 2018, Scilex Pharma, among other things, issued
and sold to the Scilex Note Purchasers senior secured notes due 2026 in an aggregate principal amount of $224,000,000 (the "Scilex Notes") for an
aggregate purchase price of $140,000,000  million (the “Scilex Notes Offering”). In connection with the Scilex Notes Offering, Scilex Pharma also entered
into an Indenture (the “Indenture”) governing the Scilex Notes with U.S. Bank National Association, a national banking association, as trustee (the
“Trustee”) and collateral agent (the “Collateral Agent”), and the Company. Pursuant to the Indenture, the Company agreed to irrevocably and
unconditionally guarantee, on a senior unsecured basis, the punctual performance and payment when due of all obligations of Scilex Pharma under the
Indenture (the "Guarantee").

The net proceeds of the Offering were approximately $89.3 million, after deducting the Offering expenses payable by Scilex Pharma and funding a

segregated reserve account ($20.0 million) (the “Reserve Account”) and a segregated collateral account ($25.0 million) (the “Collateral Account”) pursuant
to the terms of the Indenture. Funds in the Reserve Account were to be released to Scilex Pharma upon receipt by the Trustee of an officer’s certificate
under the Indenture from Scilex Pharma confirming receipt of a marketing approval letter from the FDA with respect to SP-103 (the “Marketing Approval
Letter”) on or prior to July 1, 2023. Funds in the Collateral Account were to be released upon receipt of a written consent authorizing such release from the
holders of a majority in principal amount of the Scilex Notes issued, upon the occurrence and during the continuance of an event of default at the direction
of the holders of a majority in principal amount of the Scilex Notes issued or upon the repayment in full of all amounts owed under the Scilex Notes.

The holders of the Scilex Notes are entitled to receive quarterly payments of principal of the Scilex Notes equal to a percentage, in the range of 10%

to 20% of the net sales of ZTlido for the prior fiscal quarter, beginning on February 15, 2019. If Scilex Pharma has not received the Marketing Approval
Letter by March 31, 2021, the percentage of net sales payable shall be increased to be in the range of 15% to 25%. If actual cumulative net sales of ZTlido
from October 1, 2022 through September 30, 2023 are less than 60% of a predetermined target sales threshold for such period, then Scilex Pharma will be
obligated to pay an additional installment of principal of the Scilex Notes each quarter in an amount equal to an amount to be determined by reference to
the amount of such deficiency.

F-26

 
The aggregate principal amount due under the Scilex Notes shall be increased by $28,000,000 on February 15, 2022 if actual cumulative net sales of

ZTlido from the issue date of the Scilex Notes through December 31, 2021 do not equal or exceed 95% of a predetermined target sales threshold for such
period. If actual cumulative net sales of ZTlido for the period from October 1, 2022 through September 30, 2023 do not equal or exceed 80% of a
predetermined target sales threshold for such period, the aggregate principal amount shall also be increased on November 15, 2023 by an amount equal to
an amount to be determined by reference to the amount of such deficiency.

The final maturity date of the Scilex Notes will be August 15, 2026. The Scilex Notes may be redeemed in whole at any time upon 30 days’ written

notice at Scilex Pharma’s option prior to August 15, 2026 at a redemption price equal to 100% of the then-outstanding principal amount of the Scilex
Notes. In addition, upon a change of control of Scilex Pharma (as defined in the Indenture), each holder of a Scilex Note shall have the right to require
Scilex Pharma to repurchase all or any part of such holder’s Scilex Note at a repurchase price in cash equal to 101% of the then-outstanding principal
amount thereof.

The Indenture governing the Scilex Notes contains customary events of default with respect to the Scilex Notes (including a failure to make any
payment of principal on the Scilex Notes when due and payable), and, upon certain events of default occurring and continuing, the Trustee by notice to
Scilex Pharma, or the holders of at least 25% in principal amount of the outstanding Scilex Notes by notice to Scilex Pharma and the Trustee, may (subject
to the provisions of the Indenture) declare 100% of the then-outstanding principal amount of the Scilex Notes to be due and payable. Upon such a
declaration of acceleration, such principal will be due and payable immediately. In the case of certain events, including bankruptcy, insolvency or
reorganization involving the Company or Scilex Pharma, the Scilex Notes will automatically become due and payable.

Pursuant to the Indenture, the Company and Scilex Pharma must also comply with certain covenants with respect to the commercialization of

ZTlido, as well as customary additional affirmative covenants, such as furnishing financial statements to the holders of the Scilex Notes, minimum cash
requirements and net sales reports; and negative covenants, including limitations on the following: the incurrence of debt; the payment of dividends, the
repurchase of shares and under certain conditions making certain other restricted payments; the prepayment, redemption or repurchase of subordinated
debt; a merger, amalgamation or consolidation involving Scilex Pharma; engaging in certain transactions with affiliates; and the making of investments
other than those permitted by the Indenture.

Pursuant to a Collateral Agreement by and among Scilex Pharma, the Trustee and the Collateral Agent (the “Collateral Agreement”), the Scilex

Notes will be secured by ZTlido and all of the existing and future property and assets of Scilex Pharma necessary for, or otherwise relevant to, now or in
the future, the manufacture and sale of ZTlido, on a worldwide basis (exclusive of Japan), including, but not limited to, the intellectual property related to
ZTlido, the marketing or similar regulatory approvals related to ZTlido, any licenses, agreements and other contracts related to ZTlido, and the current
assets related to ZTlido such as inventory, accounts receivable and cash and any and all future iterations, improvements or modifications of such product
made, developed or licensed (or sub-licensed) by Scilex Pharma or any of its affiliates or licensees (or sub-licensees) (including SP-103).

Pursuant to the terms of the Indenture, the Company issued an irrevocable standby letter of credit to Scilex Pharma (the “Letter of Credit”), which

provides that, in the event that (1) Scilex Pharma does not hold at least $35,000,000 in unrestricted cash (which is inclusive of the amount in the Collateral
Account) as of the end of any calendar month during the term of the Scilex Notes, (2) actual cumulative net sales of ZTlido from the issue date of the
Scilex Notes through December 31, 2021 are less than a specified sales threshold for such period, or (3) actual cumulative net sales of ZTlido for any
calendar year during the term of the Scilex Notes, beginning with the 2022 calendar year, are less than a specified sales threshold for such calendar year,
Scilex Pharma as beneficiary of the Letter of Credit, will draw, and the Company will pay to Scilex Pharma, $35,000,000 in a single lump-sum amount as a
subordinated loan. In the event that Scilex Pharma draws on, and the Company pays to Scilex Pharma, $35,000,000 in a single lump-sum amount as a
subordinated loan, each holder of the Scilex Notes had the right to require the Company to purchase all or any part of such holder’s outstanding Scilex
Notes in the principal amount of, and at a purchase price in cash equal to, $25,000,000 multiplied by such holder’s pro rata portion of the then-outstanding
Scilex Notes. The Letter of Credit will terminate upon the earliest to occur of: (a) the repayment of the Scilex Notes in full, (b) the actual net sales of
ZTlido for any calendar year during the term of the Scilex Notes exceeding a certain threshold, (c) the consummation of an initial public offering on a
major international stock exchange by Scilex Pharma that satisfies certain valuation thresholds, and (d) the replacement of the Letter of Credit with another
letter of credit in form and substance, including as to the identity and creditworthiness of issuer, reasonably acceptable to the holders of at least 80% in
principal amount of outstanding Scilex Notes.

On December 14, 2020, Scilex Pharma, the Company, the Trustee and the Agent, and the beneficial owners of the Scilex Notes and the Scilex Note

Purchasers entered into a Consent Under and Amendment No. 3 to Indenture and Letter of Credit (the “Amendment”), which amended: (i) the Indenture,
and (ii) the Letter of Credit.

Pursuant to the Amendment, the Scilex Note Purchasers agreed to release all of the aggregate $45.0 million in restricted funds held in the Reserve

Account and the Collateral Account for the purpose of consummating the repurchase of an aggregate of $45.0 million of principal amount of the Securities
from the Holders on a pro rata basis at a purchase price equal to 100% of the principal amount thereof (such repurchase, the “Effective Date Repurchase”).
In connection with the Effective Date Repurchase, the parties also

F-27

 
agreed to remove Scilex Pharma’s obligations under the Indenture to (i) repurchase $25.0 million of Securities from the holders if the Letter of Credit is
drawn on, and (ii) repurchase $20.0 million of Securities from the holders if Scilex Pharma does not receive the Marketing Approval Letter on or prior to
July 1, 2023.

The Amendment also revised the minimum cash covenant in the Indenture to provide that the amount of cash equivalents in bank accounts that

Scilex Pharma is required to have as of the end of any calendar month shall, commencing with the month ending December 31, 2020, be equal to at least
$4.0 million in the aggregate, provided that if Scilex Pharma does not effectuate (i) the December Optional Repurchase (as defined below) and (ii) at least
one of either (x) the February Optional Repurchase (as defined below) or (y) the April Optional Repurchase (as defined below), then, commencing with the
month ending April 30, 2021, and for each month thereafter, such amount shall be at least $10.0 million in the aggregate. If Scilex Pharma fails to meet the
foregoing minimum cash requirements, then Scilex Pharma will be required to draw on the Letter of Credit.

The Amendment also provides Scilex Pharma with the option, in its sole and absolute discretion, to repurchase Securities from the holders thereof
on a pro rata basis on each of December 16, 2020 (the “December Optional Repurchase”), February 12, 2021 (the “February Optional Repurchase”) and
April 13, 2021 (the “April Optional Repurchase” and, together with the December Optional Repurchase and the February Optional Repurchase, the
“Optional Repurchases”), in each case in an aggregate amount equal to the lesser of $20.0 million or the then-outstanding principal amount of Securities, at
a purchase price in cash equal to 100% of the principal amount thereof.

The Amendment further provides that in the event that the Letter of Credit is drawn upon by Scilex Pharma, then Scilex Pharma shall, within five

business days of such draw, repurchase Securities from the holders thereof on a pro rata basis in an aggregate amount equal to the lesser of $20.0 million or
the then-outstanding principal amount of Securities, at a purchase price in cash equal to 100% of the principal amount thereof.

Pursuant to the Amendment, the Holders also consented to Scilex Pharma incurring up to $10.0 million of indebtedness in connection with an

accounts receivable revolving loan facility with another lender and the incurrence of liens and the pledge of collateral to such lender in connection
therewith.

On December 14, 2020, the restricted funds in the Reserve Account and the Collateral Account were released and the Effective Date Repurchase

was effected. Scilex Pharma also effectuated the December Optional Repurchase on December 16, 2020. Following the Effective Date Repurchase and the
December Optional Repurchase, the aggregate principal amount of the Scilex Notes was reduced by an aggregate of $65.0 million. The Company
accounted for the Amendment as a debt modification under ASC Topic 470-50 as the modified terms were not substantially different than the pre-modified
terms.

On February 12, 2021, Scilex Pharma effectuated the February Optional Repurchase, which reduced the aggregate principal amount of the Scilex

Notes by $20.0 million.

To estimate the fair value of the Scilex Notes, the Company uses the discounted cash flow method under the income approach, which involves
significant Level 3 inputs and assumptions, combined with a Monte Carlo simulation as appropriate. The value of the debt instrument is based on the
present value of future principal payments and the discounted rate of return reflective of the Company’s credit risk.

The Company made principal payments of $69.8 million and $2.3 million during the fiscal years ended December 31, 2020 and 2019, respectively.

Debt discount and debt issuance costs, which are presented as a direct reduction of the Scilex Notes in the consolidated balance sheets, are amortized as
interest expense using the effective interest method. As principal repayments on the Scilex Notes are based on a percentage of net sales of ZTlido and SP-
103, if the Marketing Approval Letter is received, the Company has elected to account for changes in estimated cash flows from future net sales
prospectively. Specifically, a new effective interest rate will be determined based on revised estimates of remaining cash flows and changes in expected
cash flows will be recognized prospectively. The imputed effective interest rate at December 31, 2020 was 9.15%. The amount of debt discount and debt
issuance costs included in interest expense for the fiscal years ended December 31, 2020, 2019 and 2018 was approximately $10.6 million, $15.0 million
and $6.8 million, respectively.

The Company identified a number of embedded derivatives that require bifurcation from the Scilex Notes and that were separately accounted for in

the consolidated financial statements as derivative liabilities. Certain of these embedded features include default interest provisions, contingent rate
increases, contingent put options, optional and automatic acceleration provisions and tax indemnification obligations. The fair value of the derivative
liabilities associated with the Scilex Notes was estimated using the discounted cash flow method under the income approach combined with a Monte Carlo
simulation model. This involves significant Level 3 inputs and assumptions, including a risk adjusted net sales forecast, an effective debt yield, estimated
marketing approval probabilities for SP-103 and an estimated probability of an initial public offering by Scilex Holding that satisfies certain valuation
thresholds and timing considerations. The Company re-evaluates this assessment each reporting period.

The 2018 Purchase Agreements and Indenture, as amended, provide that, upon the occurrence of an event of default, the lenders thereunder may, by

written notice to the Company, declare all of the outstanding principal and interest under the Indenture immediately due and payable. For purposes of the
Indenture, an event of default includes, among other things, (i) a failure to pay any amounts when due under the Indenture, (ii) a breach or other failure to
comply with the covenants (including financial, notice and reporting covenants) under the Indenture, (iii) a failure to make any payment on, or other event
triggering an acceleration under, other material indebtedness of the Company, and (iv) the occurrence of certain insolvency or bankruptcy events (both
voluntary and involuntary) involving the Company or certain of its subsidiaries. The Company is subject to certain customary default clauses under the
Indenture and is in compliance with event of default clauses under the Indenture.

2018 Oaktree Term Loan Agreement

In November 2018, the Company entered into a Term Loan Agreement (the “Loan Agreement”) with certain funds and accounts managed by
Oaktree Capital Management, L.P. (collectively, the “Lenders”) and Oaktree Fund Administration, LLC, as administrative and collateral agent, for an initial
term loan of $100.0 million (the “Initial Loan”). In May 2019, the Company entered into an amendment to the Loan Agreement, under which terms the
Lenders agreed to make available to the Company $20.0 million (the “Early Conditional Loan”, and collectively, with the Initial Loan, the “Term Loans”).
The Initial Loan matured on November 7, 2023 and bore interest at a rate equal to the London Interbank Offered Rate plus the applicable margin, or 7%. In
connection with the Loan Agreement, on November 7, 2018, the Company issued to the Lenders warrants to purchase 6,288,985 shares of the Company’s
common stock (the “Initial Warrants”). The Initial Warrants have an exercise price per share of $3.28 and will be exercisable from May 7, 2019 through
May 7, 2029.

In connection with the May 2019 amendment, the Company issued to the Lenders warrants to purchase an aggregate of 1,333,304 shares of the

Company’s common stock (the “2019 Warrants”). The Company recorded a loss on derivative liabilities associated with the 2019 Warrants of $4.3 million
on the issuance date.

During the year ended December 31, 2020, the Company repaid $120.0 million of outstanding principal under the Term Loans plus approximately

$9.4 million of related prepayment premium, exit fees and accrued interest thereon. In connection with the repayment of outstanding principal, the
Company recorded a loss on debt settlement of $51.9 million.

Interest expense recognized for stated interest on the Term Loans totaled $3.0 million and $10.7 million and $1.4 million for the years ended

December 31, 2020, 2019 and 2018, respectively. Debt discount and debt issuance costs were amortized as interest expense using the effective interest
method. The amount of debt discount and debt issuance costs included in interest expense on the Term Loans for the years ended December 31, 2020, 2019
and 2018 was approximately $2.2 million $5.5 million and $0.5 million, respectively.

2018 Securities Purchase Agreement for Private Placement

In March 2018, the Company entered into a Securities Purchase Agreement (the “March 2018 Securities Purchase Agreement”) with certain

investors (the “March 2018 Purchasers”), in which the Company issued and sold to the March 2018 Purchasers, (1) convertible promissory notes in an
aggregate principal amount of $120,500,000 (the “Notes”), and (2) warrants to purchase 8,591,794 shares of the Company’s common stock (the
“Warrants”). In June 2018, the Company entered into an amendment (the “June 2018 Amendment”), in which the Company issued and sold to the March
2018 Purchasers, (1) Notes in an aggregate principal amount of $37,848,750, and (2) Warrants to purchase an aggregate of 2,698,662 shares of the
Company’s common stock.

In November 2019, the March 2018 Purchasers agreed to convert the full principal amount, plus all accrued interest into shares of the Company’s
common stock. The Company accounted for the conversion as an induced conversion of debt and recorded a loss on settlement of debt of $27.8 million.

9. Stockholders’ Equity

Amended Sales Agreement

On December 4, 2020, Sorrento Therapeutics, Inc. (the “Company”) entered into Amendment No. 1 to the Sales Agreement dated April 27, 2020,

by and between the Company and A.G.P./Alliance Global Partners (the “Agent”). The Sales Agreement provided that the Company could offer and sell
through or to the Agent up to $250.0 million in shares of its common stock. The Amendment amends the Sales Agreement to provide that the Company

the other, or (iii) the sale of all $700.0 million of shares of the Company’s common stock pursuant thereto. Under the terms of the Amended Sales
Agreement, the Agent will be entitled to a commission at a fixed rate of 3.0% of the gross proceeds from each sale of shares of the Company’s common
stock under the Amended Sales Agreement.

During the year ended December 31, 2020, the Company sold an aggregate of 30,991,918 shares of its common stock pursuant to the Sales

10. Stock Incentive and Employee Benefit Plans

2019 Stock Incentive Plan

In September 2019, the Company’s stockholders approved the Sorrento Therapeutics, Inc. 2019 Stock Incentive Plan (the “2019 Plan”). The 2019
Plan replaced and superseded the Company’s Amended and Restated 2009 Stock Incentive Plan (the “2009 Plan”) and no further awards will be granted
under the 2009 Plan. The 2019 Plan provides for the grant of incentive stock options, non-incentive stock options, stock appreciation rights, restricted stock
awards, unrestricted stock awards, restricted stock unit awards and performance awards to eligible recipients. Recipients of stock options shall be eligible to
purchase shares of the Company’s common stock at an exercise price equal to no less than the estimated fair market value of such stock on the date of
grant. The maximum term of options granted under the Stock Plan is ten years. Employee option grants generally vest 25% on the first anniversary of the
original vesting commencement date, with the balance vesting monthly over the remaining three years.

The following table summarizes stock option activity as of December 31, 2020 under the 2019 Plan and the 2009 Plan, and the changes for the

period then ended (dollar values in thousands, other than weighted-average exercise price):

During the year ended December 31, 2020, the Company also granted 37,891 shares of unrestricted stock that vested on the grant date and were
fully expensed in the period therein. The aggregate intrinsic value of options exercised during the years ended December 31, 2020, 2019 and 2018 was $4.1
million, $0.5 million and $0.1 million, respectively. The fair value of employee stock options was estimated at the grant date using the following
assumptions:

The assumed dividend yield was based on the Company’s expectation of not paying dividends in the foreseeable future. The expected volatility is

based on the historical volatility of the Company's stock. The risk-free interest rate is based on the U.S. Treasury yield curve over the expected term of the
option. The weighted average expected life of options was estimated using the average of the contractual term and the weighted average vesting term of the
options.

Under the 2019 Plan and the Company’s prior equity award and option plans, total stock-based compensation recorded as operating expense was
$15.0 million, $8.3 million and $6.2 million for the years ended December 31, 2020, 2019 and 2018, respectively. The total unrecognized compensation
cost related to unvested employee and director stock option grants as of December 31, 2020 was $40.1 million and the weighted average period over which
these grants are expected to vest is 2.8 years.

Scilex Holding Company

In June 2019, the stockholders of Scilex Holding approved the Scilex Holding Company 2019 Stock Option Plan (the “2019 Stock Option Plan”).
Under Scilex Holding, total stock-based compensation recorded as operating expenses was $5.4 million, $4.3 million and $0.3 million for the years ended
December 31, 2020, 2019 and 2018, respectively. The total unrecognized compensation cost related to unvested employee and director stock option grants
as of December 31, 2020 was $10.3 million and the weighted average period over which these grants are expected to vest is 2.2 years.

As of December 31, 2020, options to purchase 38,234,314 shares of the common stock of Scilex Holding were outstanding and 10,023,186 shares

were reserved for awards available for future issuance under the 2019 Stock Option Plan. 

Employee Stock Purchase Plan

On October 16, 2020 at the Company’s 2020 Annual Meeting of Stockholders (the “Annual Meeting”), the Company’s stockholders approved the
Company’s 2020 Employee Stock Purchase Plan (“ESPP”). Under the terms of the ESPP, the Company’s employees can elect to have up to 15% of their
annual compensation, up to a maximum of $25,000 per year, withheld to purchase shares of the Company’s common stock for a purchase price equal to
85% of the lesser of the fair market value per share (at closing) of the Company’s common stock on (i) the commencement date of the six-month offering
period, or (ii) the respective purchase date. The initial offering period commenced on November 6, 2020 and will end on May 5, 2021, with subsequent
offering periods commencing on May 6th of each year and ending on November 5th of the following year. Total stock-based compensation recorded as
operating expense for the ESPP was $0.2 million for the year ended December 31, 2020.

CEO Performance Award

On August 7, 2020, the Compensation Committee of the Company`s Board of Directors (the “Compensation Committee”) approved a grant to

Henry Ji, Ph.D., the Company’s Chairman of the Board, Chief Executive Officer and President, of a 10-year CEO performance award tied solely to
achieving market capitalization milestones (the “CEO Performance Award”), subject to approval of the Company’s stockholders at the Annual Meeting.
The CEO Performance Award consists of a 10-year option to purchase an aggregate of 24,935,882 shares of the Company’s common stock, which was
equal to 10% of the Company’s outstanding shares of common stock on the day prior to the date of grant, and vests in ten tranches. Each of the ten tranches
vests only if a market capitalization milestone is achieved, which requires two market capitalization prongs to be met to achieve each milestone: (1) a six
calendar month trailing average (based on trading days); and (2) a 30 calendar day trailing average (based on trading days). To meet the first market
capitalization milestone, the Company’s current market capitalization must increase to $5.0 billion. For the next two milestones, the Company’s market
capitalization must continue to increase in additional $2.0 billion increments. For the three milestones thereafter, the Company’s market capitalization must
increase in additional $3.0 billion increments. For the next three

F-32

 
 
 
 
 
 
 
 
 
 
 
 
   
   
   
   
   
 
 
 
 
 
milestones thereafter, the Company’s market capitalization must increase in additional $4.0 billion increments. For the final milestone, the Company’s
market capitalization must increase by an additional $5.0 billion. Thus, for Dr. Ji to fully vest in the award, the Company’s market capitalization must
increase to $35.0 billion. The exercise price per share subject to the CEO Performance Award is $17.30, which is a 20% premium to the closing sales price
of the Company’s common stock on August 7, 2020, the date the CEO Performance Award was approved by the Compensation Committee. The CEO
Performance Award was approved by the Company`s stockholders at the Annual Meeting held on October 16, 2020, which represents the date of grant for
accounting purposes.

Recognition of stock-based compensation expense of all the tranches commenced on the date of grant, as the probability of meeting the ten market

capitalization milestones is not considered in determining the timing of expense recognition. The expense will be recognized ratably over the expected
vesting period of each respective tranche. If the related market capitalization milestone is achieved earlier than its expected achievement period, then the
stock-based compensation expense for that vesting tranche will be accelerated and recorded in the period in which the associated milestone is achieved.
The market capitalization requirement is considered a market condition under FASB ASC Topic 718 Compensation – Stock Compensation and is estimated
on the grant date using Monte Carlo simulations. Key assumptions for estimating the performance-based awards fair value at the date of grant included,
volatility of the Company’s common stock price, post-vesting exercise behavior, and the derived service period.

Total stock-based compensation recorded as operating expense for the CEO Performance Award was $10.8 million for the year ended December 31,
2020. As of December 31, 2020, the Company had approximately $139.5 million of total unrecognized stock-based compensation expense remaining under
the CEO Performance Award if all market capitalization milestones are achieved. The assumptions used in determining this valuation included an expected
volatility of 91.0%, a dividend yield of zero, a risk-free interest rate of 0.75%, and an expected remaining term of 9.8 years.

Common Stock Reserved for Future Issuance

As of December 31, 2020, approximately 82.0 million shares of common stock were reserved for future issuance, comprised of 18.6 million shares

for common stock warrants, 24.9 million for the CEO Performance Award, 7.5 million reserved for issuance under the ESPP plan and approximately
30.9 million shares under stock incentive plans. As of December 31, 2020, approximately 12.1 million shares of common stock remained available for
grant under the 2019 Plan.

Employee Benefit Plan

The Company maintains a defined contribution 401(k) plan available to eligible employees. Employee contributions are voluntary and are
determined on an individual basis, limited to the maximum amount allowable under federal tax regulations. The Company made matching contributions to
the 401(k) plan totaling $1.4 million, $1.3 million and $0.9 million, for the years ended December 31, 2020, 2019 and 2018, respectively.

11. Commitments and Contingencies

Litigation

In the normal course of business, the Company may be named as a defendant in one or more lawsuits. Other than as set forth below, the Company is
not a party to any outstanding material litigation and management is currently not aware of any legal proceedings that, individually or in the aggregate, are
deemed to be material to the Company’s financial condition or results of operations.

On April 3, 2019, the Company filed two legal actions against, among others, Patrick Soon-Shiong and entities controlled by him, asserting claims
for, among other things, fraud and breach of contract, arising out of Dr. Soon-Shiong’s purchase of the drug Cynviloq™ from the Company in May 2015.
The actions allege that Dr. Soon-Shiong and the other defendants, among other things, acquired the drug Cynviloq™ for the purpose of halting its
progression to the market. Specifically, the Company has filed:

•

An arbitration demand with the American Arbitration Association in Los Angeles, California against NantPharma, LLC and Chief Executive
Officer Patrick Soon-Shiong, seeking damages in excess of $1.0 billion, as well as additional punitive damages, related to alleged fraud and
breaches of the Stock Sale and Purchase Agreement, dated May 14, 2015, entered into between NantPharma, LLC and the Company, filed as
Exhibit 10.2 to the Company’s Quarterly Report on Form 10-Q filed with the Securities and Exchange Commission (the “SEC”) on August 7,
2015. On May 24, 2019, NantCell, Inc., Dr. Soon-Shiong and Immunotherapy NANTibody LLC (“NANTibody”) General Counsel Charles
Kim filed a motion in the Los Angeles Superior Court to stay or dismiss the Company’s arbitration demand. On October 9, 2019, the Los
Angeles Superior Court denied the motion to stay or dismiss the arbitration demand, and the arbitration is ongoing. On March 5, 2020, the
Company filed a legal action against Dr. Soon-Shiong in Los Angeles Superior Court,

F-33

 
 
 
•

asserting claims for fraudulent inducement and common law fraud, arising out of Dr. Soon-Shiong’s purchase of the drug Cynviloq™ from
the Company in May 2015. The action alleges that, among other things, Dr. Soon-Shiong acquired the drug Cynviloq™ for the purpose of
halting its progression to the market. In connection with filing this civil action in the Los Angeles Superior Court, where the Company will
have the right to a jury trial against Dr. Soon-Shiong, the Company has dismissed Dr. Soon-Shiong from the related, ongoing arbitration
against NantPharma, LLC; and

An action in the Los Angeles Superior Court derivatively on behalf of NANTibody against NantCell, Inc., NANTibody Board Member and
NantCell, Inc. Chief Executive Officer Patrick Soon-Shiong, and NANTibody officer Charles Kim, related to several breaches of the June 11,
2015 Limited Liability Company Agreement for NANTibody entered into between the Company and NantCell, Inc. The suit also alleges
breaches of fiduciary duties and seeks, inter alia, a declaration that the Assignment Agreement entered into on July 2, 2017, between
NantPharma, LLC and NANTibody is void and an equitable unwinding of the Assignment Agreement. The suit calls for the restoration of
$90.05 million to the NANTibody capital account, thereby restoring the Company’s equity method investment in NANTibody to its invested
amount as of June 30, 2017 of $40.0 million. On May 24, 2019, NantCell, Inc. and Dr. Soon-Shiong filed a cross-complaint against the
Company and Dr. Ji, seeking unspecified damages, as well as additional punitive damages and specific performance, related to alleged fraud,
alleged breaches of the Exclusive License Agreement for certain antibodies (dated April 21, 2015 and entered into between NantCell, Inc.
and the Company), and tortious interference with contract. On May 24, 2019, NANTibody and NantPharma, LLC filed a new complaint in
the action against the Company and Dr. Ji, seeking unspecified damages, as well as additional punitive damages and specific performance,
related to alleged fraud, alleged breaches of the Stock Sale and Purchase Agreement, alleged breaches of the Exclusive License Agreement
for certain antibodies (dated April 21, 2015 and entered into between NantCell, Inc. and the Company), and tortious interference with
contract. On July 8, 2019, the Company and Dr. Ji filed motions to compel the cross-complaint and new action to arbitration. On October 9,
2019, the Los Angeles Superior Court granted the motions to compel to arbitration all of the claims brought by NANTibody, NantCell, Inc.
and NantPharma, LLC, and denied the motions to compel as to the claims brought by Dr. Soon-Shiong.  Subsequently, NANTibody,
NantCell, Inc., and NantPharma, LLC have re-filed their claims in arbitration. On July 21, 2020, NantPharma, LLC’s demands in arbitration
were dismissed. The arbitration claims by NANTibody and NantCell are currently pending before the American Arbitration Association. The
claims against Dr. Soon-Shiong have been stayed pending resolution of the claims filed in arbitration. The original derivative action is no
longer stayed, and the parties are currently engaged in discovery in the suit.

On May 26, 2020, Wasa Medical Holdings filed a putative federal securities class action in the U.S. District Court for the Southern District of
California, Case No. 3:20-cv-00966-AJB-DEB, against us, our President, Chief Executive Officer and Chairman of the Board of Directors, Henry Ji, Ph.D.,
and our SVP of Regulatory Affairs, Mark R. Brunswick, Ph.D. The action alleges that the Company, Dr. Ji and Dr. Brunswick made materially false and/or
misleading statements to the investing public by publicly issuing false and/or misleading statements regarding STI-1499 and its ability to inhibit the SARS-
CoV-2 virus infection and that such statements violated Section 10(b) of the Securities Exchange Act of 1934, as amended, and Rule 10b-5 promulgated
thereunder. The suit seeks to recover damages caused by the alleged violations of federal securities laws, along with the plaintiffs’ reasonable costs and
expenses incurred in the lawsuit, including counsel fees and expert fees. On June 11, 2020, Jeannette Calvo filed a second putative federal securities class
action in the U.S. District Court for the Southern District of California, Case No. 3:20-cv-01066-JAH-WVG, against the same defendants alleging the same
claims and seeking the same relief. On February 12, 2021, the U.S. District Court for the Southern District of California issued an order consolidating the
cases and appointing a lead plaintiff, Andrew Zenoff (“Plaintiff”), and lead counsel.  It is anticipated that the Plaintiff will file a consolidated amended
complaint pursuant to a court scheduling order or stipulation of the parties. No deadline for the filing of that complaint or any response thereto by
defendants has been set. The Company is defending these matters vigorously.

Operating Leases

The Company leases administrative, research and development, sales and marketing and manufacturing facilities under various non-cancelable lease

agreements. Facility leases generally provide for periodic rent increases, and many contain escalation clauses and renewal options. As of December 31,
2020, the Company’s leases have remaining lease terms of approximately 0.5 to 8.9 years, some of which include options to extend the lease terms for up
to five years, and some of which allow for early termination. Many of the Company’s leases are subject to variable lease payments. Variable lease payments
are recognized in the period in which the obligation for those payments are incurred, are not included in the measurement of the ROU assets or lease
liabilities and are immaterial. As of December 31, 2020, the Company has no finance leases.

F-34

 
 
 
Operating lease costs were approximately $10.1 million, $10.0 million and $6.1 million for the twelve months ended December 31, 2020, 2019 and

2018, respectively, and were primarily comprised of long-term operating lease costs. Short-term operating lease costs were immaterial. Supplemental

The Company has evaluated the available evidence supporting the realization of its gross deferred tax assets, including the amount and timing of

future taxable income, and has determined that it is more likely than not that the deferred tax assets will not be realized. Due to such uncertainties
surrounding the realization of the domestic deferred tax assets, the Company maintains a valuation allowance of $203.5 million against its deferred tax
assets as of December 31, 2020. Realization of the deferred tax assets will be primarily dependent upon the Company's ability to generate sufficient taxable
income prior to the expiration of its net operating losses. For 2019, the change in valuation allowance also included approximately $8.1 million attributable
to the Semnur Pharmaceuticals, Inc. acquisition.

As of December 31, 2020, the Company had $566.8 million, $185.8 million and $19.9 million of federal, state and foreign net operating loss
carryforwards, respectively. The net operating loss carryforwards begin to expire in 2034, 2028 and 2024 for federal, state and foreign, respectively.

The Company also had research and development and orphan drug income tax credits of $19.2 million and $10.8 million for federal and state,

respectively. The federal income tax credits begin to expire in 2029, while the state income tax credits carryforward indefinitely.

Internal Revenue Code Section 382 rules apply to limit a corporation's ability to utilize existing net operating loss and tax credit carryforwards once
the corporation experiences an ownership change as defined in Section 382. The Company has undergone an ownership change in a prior year. For the year
ended December 31, 2020, there was no impact of such limitations on the Company’s income tax provision.

The Company is subject to taxation in the U.S., various state tax jurisdictions and various foreign tax jurisdictions. The Company's tax years starting

on January 1, 2007 through December 31, 2020 are open and subject to examination by the U.S. and state taxing authorities due to the carryforward of net
operating losses and research and development credits. There are no active audits as of December 31, 2020.

At December 31, 2020, 2019 and 2018, $5.6 million, $4.4 million and $3.6 million, respectively, of the Company’s total unrecognized tax benefits,

if recognized, would impact the effective tax rate, however given the full valuation allowance in the jurisdiction in which the unrecognized tax benefits
relate to, the impact on the effective tax rate would be nil.

The Company’s policy is to recognize interest and penalties related to income tax matters in income tax expense. No interest or penalties have been

recognized as of and for the periods ended December 31, 2020, 2019 or 2018.

The Company believes that no material amount of the liabilities for uncertain tax positions will expire within 12 months of December 31, 2020.

13. Related Party Agreements and Other

Jaisim Shah, a member of the Company’s Board of Directors, was Semnur’s Chief Executive Officer, a member of its Board of Directors and a

stockholder of Semnur prior to the acquisition transaction.

Semnur is party to an Assignment Agreement with Shah Investor LP, pursuant to which Shah Investor LP assigned certain intellectual property to

Semnur and Semnur agreed to pay Shah Investor LP a contingent quarterly royalty in the low-single digits based on quarterly net sales of any
pharmaceutical formulations for local delivery of steroids by injection developed using such intellectual property, which would include SEMDEXA.
Mahendra Shah, Ph.D., who served on the board of directors of Scilex Holding from March 2019 to October 2020, is the managing partner of Shah
Investor LP.

As of December 31, 2020, approximately 14.7% of the outstanding capital stock of Scilex Holding represented a noncontrolling interest and was
held by ITOCHU CHEMICAL FRONTIER Corporation. Scilex Pharma has entered into a product development agreement (the “Product Development
Agreement”) with ITOCHU CHEMICAL FRONTIER Corporation and another party (together, the “Developers”), which together serve as the sole
manufacturer and supplier to Scilex Pharma for lidocaine tape products, including ZTlido and SP-103 (each, a “Product”). During the year ended December
31, 2020, Scilex Pharma purchased approximately $1.0 million of inventory from the Developers pursuant to the Product Development Agreement.
Pursuant to the Product Development Agreement, Scilex Pharma is required to make aggregate royalty payments between 25% and 35% to the Developers
based on net profits. Net profits are defined as net sales, less cost of goods and marketing expenses. Net sales are defined as total gross sales of any
Product, less all applicable deductions, to the extent accrued, paid or allowed in the ordinary course of business with respect to the sale of such Product,
and to the extent that they are in accordance with U.S. GAAP. If Scilex Pharma were to sublicense the licensed technologies, the Developers will receive
the same proportion of any sub-licensing fees received therefrom. The Product Development Agreement will continue in full force and effect until October
2, 2028, the date that is ten years from the date of the first commercial sale of ZTlido. The Product Development Agreement will renew automatically for
subsequent successive one-year renewal periods unless Scilex Pharma or the Developers terminate it upon 6-month written notice.

On July 15, 2020, the Company entered into a consulting agreement with Kim Janda, Ph.D., a member of the Company’s Board of Directors,

pursuant to which Dr. Janda will provide consulting and advisory services in exchange for (i) a one-time fee of $250,000,

F-37

 
 
 
 
 
   
   
 
   
   
   
 
 
which is payable at a rate of 1/12th per month over twelve months, and (ii) an option to purchase up to 150,000 shares of the Company’s common stock,
which was granted on August 7, 2020 and vests at a rate of 1/48th per month commencing on July 15, 2020.

On May 13, 2020, the Company entered into a license agreement with Pulsar Therapeutics, Inc. (“Pulsar”), pursuant to which it licensed Pulsar’s

nanoparticle technology for vaccine and antibody uses in exchange for a cash payment, certain royalties of net sales, a sublicense fee and an investment by
the Company in Pulsar through the transfer of 1.0 million shares of the Company’s common stock in exchange for a 5.0% equity interest in Pulsar. As of
the date of the investment, Henry Ji, Ph.D., a member of the Company’s Board of Directors and the Company’s Chief Executive Officer and President, was
a director and chairperson of the board of directors of Pulsar and owned approximately 45.0% of Pulsar’s outstanding shares, and Jaisim Shah, a member
the Company’s Board of Directors, owned approximately 5.0% of Pulsar’s outstanding shares.

On May 15, 2020, the Company acquired a 50% equity interest in Cytimm Therapeutics, Inc. (“Cytimm”) in exchange for an investment of $2.5

million by the Company. As of the date of the acquisition, Henry Ji, Ph.D., a member of the Company’s Board of Directors and the Company’s Chief
Executive Officer and President, was a director, the chairperson of the board of directors and a stockholder of Cytimm.

14. Segment Information

As of January 1, 2019, the Company realigned its businesses into two operating and reportable segments, Sorrento Therapeutics and Scilex. The

Company reports segment information based on the management approach. The management approach designates the internal reporting used by the Chief
Operating Decision Maker (“CODM”), which is the Company’s Chief Executive Officer, for making decisions and assessing performance as the source of
the Company’s reportable segments. The CODM allocates resources and assesses the performance of each operating segment based on licensing, product
sales and services revenue, operating expenses, and operating income (loss) before interest and taxes. The Company has determined its reportable segments
to be Sorrento Therapeutics and Scilex based on the information used by the CODM.

Sorrento Therapeutics. The Sorrento Therapeutics segment is organized around the Company’s immuno-oncology therapeutic area, leveraging its

proprietary G-MAB™ antibody library and targeted delivery modalities to generate the next generation of cancer therapeutics. These modalities include
proprietary CAR-T, DAR-T, and ADCs as well as bispecific antibody approaches. Additionally, this segment also includes Sofusa®, a drug delivery
technology that delivers biologics directly into the lymphatic system to potentially achieve improved efficacy and fewer adverse effects than standard
parenteral immunotherapy, and RTX, which is a non-opioid-based neurotoxin and is currently in clinical trials for late stage cancer pain and osteoarthritis.

Scilex. The Scilex segment is largely organized around the Company’s non-opioid pain management operations. Revenues from the Scilex segment

are exclusively derived from the sale of ZTlido.

•

•

In October 2018, Scilex Pharma commercially launched ZTlido and began recognizing revenue.

Semnur’s SEMDEXATM (SP-102) compound could become the first FDA-approved epidural steroid product for the treatment of sciatica.
SEMDEXATM has been awarded fast track status by the FDA.

The Company manages its assets on a company basis, not by segments, as many of its assets are shared or commingled. With the exception of
unrestricted cash balances, the Company’s CODM does not regularly review asset information by reportable segment. The majority of long-lived assets for
both segments are located in the United States.

The following table presents information about the Company’s reportable segments for the twelve months ended December 31, 2020, 2019 and

16. Loss Per Share

For the years ended December 31, 2020, 2019, and 2018, basic earnings per share of common stock is computed by dividing net income by the
weighted average number of shares of common stock outstanding during the period. Diluted earnings per share of common stock is calculated to give effect
to all dilutive securities, using the treasury stock method and the if-converted method for potentially dilutive shares of common stock issuable upon the
Semnur Share Exchange, which is described in Note 7.

The following table sets forth the reconciliation of basic and diluted earnings per share for the years ended December 31, 2020, 2019 and 2018 (in

thousands, except per share):

Exhibit 4.18

The authorized capital stock of Sorrento Therapeutics, Inc., a Delaware corporation (the “Company”), consists of:

DESCRIPTION OF SECURITIES OF SORRENTO THERAPEUTICS, INC.

•

•

750,000,000 shares of common stock, $0.0001 par value per share (“Common Stock”); and

100,000,000 shares of preferred stock, $0.0001 par value per share (“Preferred Stock”).

Common Stock

Except as otherwise expressly provided in the Company’s Restated Certificate of Incorporation, as amended (the “Certificate of
Incorporation”) or as required by applicable law, all shares of Common Stock have the same rights and privileges and rank
equally, share ratably and are identical in all respects as to all matters, including, without limitation, those described below:

Voting rights. Each holder of Common Stock is entitled to one vote per share on each matter that requires stockholder
approval. Holders of Common Stock do not have any cumulative voting rights. There is no provision for cumulative
voting for the election of directors, which means that more than one-half of the shares voted can elect all of the
directors then standing for election. The Company’s Amended and Restated Bylaws (the “Bylaws”) provide that all
elections shall be determined by a plurality of votes cast, and except as otherwise required by law or the rules and
regulations of any stock exchange applicable to the Company, all other matters shall be determined by a majority of
votes cast affirmatively or negatively.

Dividend rights. The holders of outstanding shares of Common Stock are entitled to receive ratably such dividends, if
any, as may be declared by the Company’s board of directors (the “Board”) out of legally available funds. However, the
current policy of the Board is to retain earnings, if any, for the operations and potential expansion of the business.

Liquidation rights. Upon liquidation, dissolution or winding-up, the holders of Common Stock are entitled to share
ratably in all of the Company’s assets which are legally available for distribution, after payment of or provision for all
liabilities.

No preemptive or similar rights. The holders of Common Stock have no preemptive, subscription, redemption or
conversion rights.

Anti-Takeover Provisions. See the below section titled “Anti-Takeover Effects of Provisions of the Company’s
Certificate of Incorporation, Bylaws and the DGCL”.

Listing

The Common Stock is listed on the Nasdaq Capital Market under the symbol “SRNE.”

 
 
 
 
 
 
 
 
 
Preferred Stock

The Certificate of Incorporation provides that the Board may by resolution, without further vote or action by the stockholders,
establish one or more classes or series of Preferred Stock having the number of shares and relative voting rights, designation,
dividend rates, liquidation, and other rights, preferences and limitations as may be fixed by them without further stockholder
approval. Once designated by the Board, each series of Preferred Stock will have specific financial and other terms that will be
set forth in the applicable certificate of designation for the series. Prior to the issuance of shares of each series of Preferred Stock,
the Board is required by the General Corporation Law of the State of Delaware (the “DGCL”) and the Certificate of
Incorporation to adopt resolutions and file a certificate of designation with the Secretary of State of the State of Delaware. The
certificate of designation fixes for each class or series the designations, powers, preferences, rights, qualifications, limitations and
restrictions, including, but not limited to, some or all of the following:

•

•

The distinctive designation of such series and the number of shares which shall constitute such series, which number
may be increased (except where otherwise provided by the Board in creating such series) or decreased (but not below
the number of shares thereof then outstanding) from time to time by resolution of the Board;

The rate and manner of payment of dividends payable on shares of such series, including the dividend rate, date of
declaration and payment, whether dividends shall be cumulative and the conditions upon which and the date from
which such dividends shall be cumulative;

• Whether shares of such series shall be redeemable, the time or times when, and the price or prices at which, shares of

such series shall be redeemable, the redemption price, the terms and conditions of redemption and the sinking fund
provisions, if any, for the purchase or redemption of such shares;

•

•

•

•

The amount payable on shares of such series and the rights of holders of such shares in the event of any voluntary or
involuntary liquidation, dissolution or winding up of the affairs of the Company;

The rights, if any, of the holders of shares of such series to convert such shares into, or exchange such shares for, shares
of Common Stock, other securities or shares of any other class or series of Preferred Stock and the terms and conditions
of such conversion or exchange;

The voting rights, if any, and whether full or limited, of the shares of such series, which may include no voting rights,
one vote per share or such higher or lower number of votes per share as may be designated by the Board; and

The preemptive or preferential rights, if any, of the holders of shares of such series to subscribe for, purchase, receive or
otherwise acquire any part of any new or additional issue of stock of any class, whether now or hereafter authorized, or
of any bonds,

2

 
 
 
 
 
 
 
 
debentures, notes or any of the Company’s other securities, whether or not convertible into shares of Common Stock.

All shares of Preferred Stock offered hereby will, when issued, be fully paid and nonassessable, including shares of Preferred
Stock issued upon the exercise of preferred stock warrants or subscription rights, if any.

Although the Board has no intention at the present time of doing so, it could authorize the issuance of a series of Preferred Stock
that could, depending on the terms of such series, impede the completion of a merger, tender offer or other takeover attempt.

Warrants

As of December 31, 2020, the Company had outstanding warrants to purchase an aggregate of 18,604,896 shares of Common
Stock as follows:

•

•

•

•

•

•

•

warrants to purchase an aggregate of 34,642 shares with an exercise price of $12.99 per share, all of which are
currently exercisable and expire on March 31, 2021, all of which shall be automatically exercised on a “cashless” basis
upon expiration if the fair market value of the Common Stock is greater than the exercise price of the warrants on the
expiration date of the warrants;

warrants to purchase an aggregate of 2,424,242 shares with an exercise price of $2.61 per share, all of which are
currently exercisable and expire on June 21, 2023;

warrants to purchase an aggregate of 2,663,012 shares with an exercise price of $3.28 per share, all of which are
currently exercisable (subject to certain beneficial ownership limitations) and expire on December 13, 2023;

warrants to purchase an aggregate of 500,000 shares with an exercise price of $3.28 per share, all of which are
currently exercisable and expire on May 7, 2029;

warrants to purchase an aggregate of 1,250,000 shares with an exercise price of $3.94 per share, all of which are
currently exercisable and expire on November 3, 2029;

Series A warrants to purchase an aggregate of 6,033,000 shares with an exercise price of $3.75 per share, all of which
are currently exercisable (subject to certain beneficial ownership limitations) and expire on July 2, 2029, all of which
shall be automatically exercised on a “cashless” basis upon expiration in accordance with the terms of the Series A
warrants;

Series C warrants to purchase an aggregate of 5,250,000 shares with an exercise price of $3.75 per share, all of which
are currently exercisable (subject to certain beneficial ownership limitations) and expire on July 2, 2029, all of which
may be automatically exercised on a “cashless” basis upon expiration in accordance with the terms of the Series C
warrants; and

3

 
 
 
 
 
 
 
 
 
•

warrants to purchase an aggregate of 450,000 shares with an exercise price of $2.40 per share, all of which are
currently exercisable (subject to certain beneficial ownership limitations) and expire on October 9, 2026, all of which
shall be automatically exercised on a “cashless” basis upon expiration in accordance with the terms of the warrants.

All of the outstanding warrants contain provisions for the adjustment of the exercise price in the event of stock dividends, stock
splits or similar transactions. In addition, certain of the warrants contain a “cashless exercise” feature that allows the holders
thereof to exercise the warrants without a cash payment to the Company under certain circumstances. Certain of the warrants also
contain provisions that provide certain rights to warrantholders in the event of a fundamental transaction, including a merger or
consolidation with or into another entity, such as:

•

•

•

the right to receive the same amount and kind of consideration paid to the holders of Common Stock in the fundamental
transaction;

the right to require the Company to repurchase the unexercised portion of certain warrants at the warrant’s respective
fair value using the Black Scholes option pricing formula; or

the right to require the Company or a successor entity to redeem the unexercised portion of certain warrants for the
same consideration paid to holders of Common Stock in the fundamental transaction at the warrant’s respective fair
value using the Black Scholes option pricing formula.

Anti-Takeover Effects of Certain Provisions of the Company’s Certificate of Incorporation, Bylaws and General
Corporation Law of the State of Delaware

Certain provisions of the Certificate of Incorporation, the Bylaws and the DGCL may have the effect of discouraging potential
acquisition proposals or tender offers or delaying or preventing a change in control. It is possible that these provisions could
make it more difficult to accomplish or could deter transactions that stockholders may otherwise consider to be in their best
interest or in the Company’s best interests, including attempts by stockholders to replace or remove the Company’s management.

These provisions, 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 the Company to first negotiate with the Board.
These provisions may delay or prevent someone from acquiring or merging with the Company, which may cause the market price
of the Common Stock to decline.

Blank Check Preferred Stock

The Board is authorized to create and issue from time to time, without stockholder approval, up to an aggregate of 100,000,000
shares of Preferred Stock in one or more series and to establish the number of shares of any series of Preferred Stock and to fix
the designations, powers, preferences and rights of the shares of each series and any qualifications, limitations or restrictions of
the shares of each series.

4

 
 
 
 
 
The authority to designate Preferred Stock may be used to issue a series of Preferred Stock, or rights to acquire Preferred Stock,
that could dilute the interest of, or impair the voting power of, holders of the Common Stock or could also be used as a method of
determining, delaying or preventing a change of control.

Advance Notice Bylaws

The Bylaws contain an advance notice procedure for stockholder proposals to be brought before any meeting of stockholders,
including proposed nominations of persons for election to the Board. Stockholders at any meeting will only be able to consider
proposals or nominations specified in the notice of meeting or brought before the meeting by or at the direction of the Board or
by a stockholder who was a stockholder of record on the record date for the meeting, who is entitled to vote at the meeting and
who has given the Company’s corporate secretary timely written notice, in proper form, of the stockholder’s intention to bring
that business before the meeting. Although the Bylaws do not give the Board the power to approve or disapprove of stockholder
nominations of candidates or proposals regarding other business to be conducted at a special or annual meeting, the Bylaws may
have the effect of precluding the conduct of certain business at a meeting if the proper procedures are not followed or may
discourage or deter a potential acquirer from conducting a solicitation of proxies to elect its own slate of directors or otherwise
attempting to obtain control of the Company.

Choice of Forum

The Bylaws provide that, unless the Board consents to an alternative forum, the Court of Chancery in the State of Delaware will
be the sole and exclusive forum for: (i) any derivative action or proceeding brought by or on behalf of the Company; (ii) any
direct action asserting a claim against the Company or any of its directors or officers pursuant to any of the provisions of the
DGCL, the Certificate of Incorporation or the Bylaws; (iii) any action asserting a claim of breach of fiduciary duties owed by any
of its directors, officers or other employees to its stockholders; or (iv) any action asserting a violation of Delaware decisional law
relating to its internal affairs. This provision does not apply to (a) actions in which the Court of Chancery in the State of
Delaware concludes that an indispensable party is not subject to the jurisdiction of Delaware courts, or (b) actions in which a
federal court has assumed exclusive jurisdiction to a proceeding. This choice of forum provision is not intended to apply to any
actions brought under the Securities Act or the Exchange Act. Section 27 of the Exchange Act creates exclusive federal
jurisdiction over all suits brought to enforce any duty or liability created by the Exchange Act or the rules and regulations
thereunder. As a result, the exclusive forum provision will not apply to suits brought to enforce any duty or liability created by
the Exchange Act or any other claim for which the federal courts have exclusive jurisdiction. However, the Bylaws do not relieve
the Company of its duties to comply with federal securities laws and the rules and regulations thereunder, and its stockholders
will not be deemed to have waived the Company’s compliance with these laws, rules and regulations. The Bylaws also provide
that any person or entity purchasing or otherwise acquiring any interest in shares of capital stock of the Company will be deemed
to have notice of and consented to this choice of forum provision.

This choice of forum provision in the Bylaws may limit a stockholder’s ability to bring a claim in a judicial forum that it finds
favorable for disputes with the Company or its directors, officers

5

 
or other employees, which may discourage such lawsuits against the Company and its directors, officers and other employees. In
addition, stockholders who do bring a claim in the Court of Chancery in the State of Delaware could face additional litigation
costs in pursuing any such claim, particularly if they do not reside in or near Delaware. Furthermore, the enforceability of similar
choice of forum provisions in other companies’ governing documents has been challenged in legal proceedings, and it is possible
that a court could find these types of provisions to be inapplicable or unenforceable.

Interested Stockholder Transactions

The Company is subject to Section 203 of the DGCL, which prohibits “business combinations” between a publicly-held
Delaware corporation and an “interested stockholder,” which is generally defined as a stockholder who is a beneficial owner of
15% or more of a Delaware corporation’s voting stock for a three-year period following the date that such stockholder became an
interested stockholder, unless: (i) the transaction is approved by the board of directors before the date the interested stockholder
attained that status; (ii) upon consummation of the transaction which resulted in the stockholder becoming an interested
stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the
transaction commenced; or (iii) on or after the date of the transaction, the transaction is approved by the board of directors and
authorized at a meeting of stockholders, and not by written consent, by the affirmative vote of at least 66 2/3% of the outstanding
voting stock that is not owned by the interested stockholder. In general, the DGCL defines a business combination to include the
following: (a) any merger or consolidation involving the corporation and the interested stockholder; (b) any sale, transfer, pledge
or other disposition of 10% or more of the assets of the corporation involving the interested stockholder; (c) subject to certain
exceptions, any transaction that results in the issuance or transfer by the corporation of any stock of the corporation to the
interested stockholder; (d) any transaction involving the corporation that has the effect of increasing the proportionate share of
the stock of any class or series of the corporation beneficially owned by the interested stockholder; or (e) the receipt by the
interested stockholder of the benefit of any loans, advances, guarantees, pledges or other financial benefits provided by or
through the corporation.

Filling Vacancies

The Certificate of Incorporation provides that the number of directors shall be fixed from time to time exclusively by the Board
pursuant to a resolution adopted by a majority of the total number of authorized directors whether or not there exist any vacancies
in previously authorized directorships. As of December 31, 2020, the Board consists of seven directors.

In the event of a vacancy on the Board, however occurring, including a vacancy resulting from an increase in the size of the
Board, unless otherwise required by law or by resolution of the Board, such vacancy shall be filled only by a majority vote of the
directors then in office, though less than a quorum (and not by stockholders), and directors so chosen shall serve for the
remainder of the full term of the director for which the vacancy was created or occurred or until such director’s successor shall
have been duly elected and qualified. This system of electing and filling vacancies may tend to discourage a third party from
making a tender offer or otherwise

6

 
attempting to obtain control of the Company, because it generally makes it more difficult for stockholders to replace a majority of
the directors.

Removal of Directors

The Certificate of Incorporation provides for the removal of any of the Company’s directors only for cause and only by the
affirmative vote of the holders of at least 67% of the voting power of all of the then outstanding shares of the Company’s capital
stock then entitled to vote at an election of directors, voting together as a single class. However, in December 2015, the Delaware
Chancery Court issued a decision, In Re VAALCO Energy, Inc., in which the court interpreted Section 141(k) of the DGCL and
held that if a company does not have (i) a classified board of directors or (ii) cumulative voting in election of directors, then such
company may not provide in its certificate of incorporation or bylaws that its directors may be removed only for cause. Prior to
the VAALCO decision, it was not clear whether Section 141(k) prohibits this type of provision when the company does not have
classified board or cumulative vote. The VAALCO decision made it clear that the removal provision in the Certificate of
Incorporation is now invalid. As previously disclosed in a Current Report on Form 8-K filed by the Company on April 18, 2018,
the Board resolved that, until such time as an amendment to the Certificate of Incorporation is approved by the Company’s
stockholders to permit stockholders to remove the Company’s directors with or without cause by a majority of stockholders, the
Company will not enforce the director removal provision of the Certificate of Incorporation to the extent it purports to limit
removal of directors by stockholders only for cause or only by a supermajority of the voting power of all of the then-outstanding
shares of capital stock of the Company.

No Stockholder Action by Written Consent; Special Meetings

The Certificate of Incorporation eliminates the right of stockholders to act by written consent without a meeting and the right to
call a special meeting of stockholders or to require that the Board call a special meeting, except as may be required by statute.

Amendment of Charter Provisions

The amendment of any of the above provisions in the Certificate of Incorporation, except for the provision making it possible for
the Company’s board of directors to issue undesignated Preferred Stock, would require approval by a stockholder vote by the
holders of at least 67% of the voting power of the then outstanding shares of capital stock entitled to vote generally in the election
of directors.

The provisions of the DGCL and the Certificate of Incorporation could have the effect of discouraging others from attempting
hostile takeovers and, as a consequence, they may also inhibit temporary fluctuations in the market price of the Common Stock
that often result from actual or rumored hostile takeover attempts. These provisions may also have the effect of preventing
changes in the Company’s management. It is possible that these provisions could make it more difficult to accomplish
transactions that stockholders may otherwise deem to be in their best interests.

ARTICLE I
DEFINITIONS; INTERPRETATION

Section  1.1

Definitions.  For  the  purposes  of  this  Agreement,  the  following  terms  have  the  meanings  set  forth

below:

“Affiliate” means, as to any Person, any other Person who, directly or indirectly, controls, is controlled by, or is under common
control with, such Person. For purposes of this definition, the term “control” of a Person means: (a) the power to vote, directly or indirectly,
fifty percent (50%) or more of the securities having ordinary voting power for the election of directors of such Person; or (b) the possession,
directly  or  indirectly,  of  the  power  to  direct  or  cause  the  direction  of  the  management  and  policies  of  such  Person,  whether  through  the

Page 2 of 23

“Commercially Reasonable Efforts” means efforts and the deployment of a quantity and quality of resources consistent with the
exercise  of  diligent  efforts  and  reasonable  and  prudent  scientific  and  business  judgment,  as  applied  to  other  pharmaceutical  products  of
similar  potential,  characteristics,  and  market  size  by  the  Party  in  question,  where  the  products  are  in  a  similar  stage  of  development  or
commercialization and with similar market potential and product life, taking into account the safety and efficacy of the products, competitive
products  in  the  marketplace,  proprietary  position  of  the  products  (including  patent  coverage  and  regulatory  exclusivity),  the  regulatory
structure involved, anticipated or approved labelling, anticipated profitability of the products (including pricing and reimbursement), and all
other relevant factors, and in all cases taking into account and subject to such Party’s reasonable business judgment. The term “Commercially
Reasonable Efforts” shall not be deemed to require Sorrento to give any guarantee to PSC.

“Controlled”  or  “Controls”  means,  with  respect  to  an  item  of  Know-How  or  Intellectual  Property  Rights,  Generated  Data,
Regulatory Materials, contracts, or other rights, the right (whether by ownership, license or other authorization) to grant and authorize the

“Cover”  means,  with  respect  to  any  subject  matter,  the  manufacture,  use,  performance,  sale,  offering  for  sale,  importation,
exportation or other exploitation of such subject matter would infringe a claim of a patent or patent application at the time thereof absent
ownership or license therein or thereto, as applicable. As used in this definition, “infringe” shall include direct infringement, contributorily
infringing  or  inducing  the  infringement  of  such  claim.  For  clarity,  with  respect  to  a  claim  within  a  patent  application,  “Cover”  includes  a
claim in such patent application if such claim were issued as then prosecuted. “Covered” and “Covering” shall have correlative meanings.

“Data” means any data (whether pre-clinical, clinical, or otherwise) for the Licensed Materials or any Licensed Product that is

Controlled by PSC.

“Field” means and includes all fields of use of allogeneic adipose-derived stem cells for or in respect of human health, including

(a) was or becomes generally known to the public by means other than a breach by the Receiving Party of a
contractual,  legal,  or  fiduciary  duty  of  confidentiality  owed  to  the  Disclosing  Party,  its  Affiliates,  its
subcontractors (if applicable), or any of its or their Representatives;

(b)

shown  by  Recipient’s  then-contemporaneous  written  files  and  records  kept  in  the  ordinary  course  of
business; or

Royalty Payments.

Royalties. During the applicable Royalty Term (as defined in Section 4.3(b)  below),  on  a
Royalty-Bearing  Product-by-Royalty-Bearing  Product  and  country-by-country  basis,  Sorrento  shall  pay  to  PSC  a  royalty  equal  to  the

such country (the “Royalty Term”) and shall expire twenty (20) years thereafter.

(b)

Section 4.4

Sublicense Revenue. For all Sublicense Revenue received from Sublicensee to Sorrento, […***…]
percent ([…***…]%) shall be paid to PSC. “Sublicense Revenue” shall mean all revenue from a Sublicensee attributable to the granting of a
sublicense hereunder, excluding (except as stated below) royalties based on the sales of products by the Sublicensees for which the Section
4.3(a)  royalties  are  paid  to  PSC,  but  including  up-front  payments,  fixed  or  periodic  fees,  and  milestone  fees.  For  the  avoidance  of  doubt,
Sublicense Revenue does not include loans or other debt, equity, investments, or consideration arising out of a sale of any business or assets
of Sorrento.

Section  4.5

Records  and  Audit  Rights.  Sorrento  will  maintain  records  in  sufficient  detail  to  permit  PSC  to
confirm  the  accuracy  of  Sorrento’s  calculations  of  payments  owed  under  this  Agreement.  Such  records  shall  be  available  for  audit  and
inspection during regular business hours for a period of three (3) years from the end of the calendar quarter to which they pertain, and not
more often than once each calendar year, unless the audit reveals non-compliance or underpayment. PSC shall provide Sorrento with thirty
(30)  calendar  days’  prior  written  notice  of  such  audit.  Audits  and  inspections  may  be  conducted  only  by  an  internationally  recognized
certified  public  accounting  firm  mutually  agreed  upon  by  Sorrento  and  PSC,  and  who  agrees  to  be  bound  by  a  reasonable  confidentiality
agreement. The mutually agreed upon certified public accounting firm may examine Sorrento’s records relating to this Agreement for the sole
purpose of verifying the accuracy of the aforesaid calculations. With regard to such calculations, the accountants shall disclose to PSC, with a
copy to Sorrento, only whether such calculations are correct or incorrect, and the amount of discrepancy, if any. Once examined, such books
and records will no longer be subject to further examination by PSC under this Section 4.4. Any amounts shown to have been underpaid shall
be paid by Sorrento to PSC and any amounts shown to have been overpaid shall be refunded by PSC to Sorrento, in each case, within forty-
five (45) calendar days from the accountant’s report. PSC shall bear the full cost of such audit unless such audit discloses an underpayment of
more than […***…] percent ([…***…]%) of the amount actually owed during the applicable calendar quarter, in which case Sorrento shall
reimburse PSC for its reasonable Third Party out-of-pocket costs incurred for such audit.

Section 4.6

Taxes. Each Party shall be responsible for its own tax liabilities arising under this Agreement. Subject
to this Section 4.5, PSC shall be liable for all income, value added, sales, and other taxes (including interest) (“Taxes”) imposed upon any
payments or other consideration made by Sorrento to PSC under this Agreement (“Agreement Payments”). If Applicable Laws require the
withholding of

 
 
 
License Agreement
Page 13 of 23

Taxes, Sorrento shall make withholding payments in a timely manner and shall subtract the amount thereof from the Agreement Payments.
Sorrento  shall  promptly  (as  available)  submit  to  PSC  appropriate  proof  of  payment  of  the  withheld  Taxes  as  well  as  the  official  receipts
within a reasonable period of time. Notwithstanding the foregoing, if as a result of PSC changing its domicile or other circumstances outside
of Sorrento’s control, additional Taxes become due that would not have otherwise been due hereunder with respect to Agreement Payments,
PSC shall be responsible for all such additional Taxes.

Section  4.7  Grant  Revenue.    PSC  has  applied  for  a  California  Institute  of  Regenerative  Medicine  (“CIRM")  grant  for
approximately  $2.6M.    PSC  and  Sorrento  will  cooperate  to  attempt  to  get  this  grant  awarded  and  to  attempt  to  get  the  grant  sponsorship
transferred to Sorrento.  If the transfer is successful, Sorrento agrees to abide by all of the rules and regulations associated with the grant.  If
the CIRM grant is transferred to Sorrento, then as a fee for PSC’s prior work related to the grant, Sorrento will, to the extent permitted by
Applicable  Law,  pay  to  PSC  a  sum  equal  to  […***…]%  of  all  those  CIRM  grant  dollars  received  by  Sorrento,  which  sum  shall  be  paid
within thirty (30) days after receipt by Sorrento.  

ARTICLE V
INTELLECTUAL PROPERTY OWNERSHIP; PATENT PROSECUTION AND ENFORCEMENT

Section 5.1

Prosecution. Subject to this Article V, PSC shall have the sole right (but not the obligation), to control
the  filing  and  prosecution,  at  its  expense,  and  using  patent  counsel  chosen  by  PSC,  any  patents  and  patent  applications  for  the  Licensed
Intellectual  Property  Rights;  provided,  however,  that  PSC  shall:  (a)  keep  Sorrento  reasonably  informed  with  respect  to  the  status  of  such
matters; (b) provide copies of all material submissions to any patent office related to such matters; and (c) give Sorrento an opportunity to
review  and  comment  on  the  nature  and  text  of  any  new  or  pending  patent  applications  and  consider  in  good  faith  any  comments  from
Sorrento regarding steps that might be taken to strengthen patent protection with respect to any such patent applications and shall conduct
discussions  with  Sorrento  on  a  reasonable  basis  regarding  the  patent  prosecution  strategy  for  the  Licensed  Intellectual  Property  Rights.  If
PSC elects not to file or prosecute any patents or patent applications for the Licensed Intellectual Property Rights then Sorrento shall have the
option to take over responsibility and the expenses for such patent matters; and if Sorrento elects to do so, then PSC will promptly (and in all
cases at last ninety (90) days prior to any applicable deadline necessary to keep such patents or patent applications subsisting and in full force
and effect) transfer to Sorrento, free of charge, the files for such patent matters; and thereafter, such patents shall be owned jointly by both
PSC and Sorrento, and such patents shall no longer be considered for purposes of determining a Royalty-Bearing Product.

Section  5.2

Maintenance.  PSC  will  pay  all  maintenance,  annuity,  and  like  fees  and  amounts  to  maintain  all
Licensed Intellectual Property Rights as subsisting and in full force and effect. If PSC elects not to pay any maintenance, annuity, or other
such fees for any patents or patent applications for the Licensed Intellectual Property Rights then, then Sorrento shall have the option to take
over responsibility and expense for such patent matters; and if Sorrento elects to do so, then  PSC will promptly (and in all cases at last ninety
(90) days prior to any applicable payment deadline) transfer to Sorrento, free of charge, the files for such patent matters; and thereafter such
patents  will  be  jointly  owned  by  both  PSC  and  Sorrento.;  and  such  patents  will  no  longer  be  considered  for  purposes  of  determining  a
Royalty-Bearing Product. In the case where any patents or patent applications become jointly owned by PSC and Sorrento under Section 5.1
or this Section 5.2, the ownership rights of PSC will still be subject to the restrictions on use by PSC pursuant to this Agreement. For such
patents and patent applications, Sorrento will have exclusive control over future filing, prosecution, maintenance, and enforcement decisions
with respect to such patents and patent applications; and at the request and expense of Sorrento, PSC shall provide to Sorrento all reasonable
assistance  and  cooperation  to  transfer  such  patents  and  patent  applications  to  Sorrento  and  assist  in  the  enforcement  thereof,  including
providing any necessary powers of attorney and

 
 
License Agreement
Page 14 of 23

assignments of employees of PSC and its Affiliates and Third Party contractors and executing any other required documents or instruments.

Section 5.3

Patent Enforcement.

(a)

By Sorrento. Sorrento shall have the exclusive right (but not the obligation) at its expense to
enforce the Licensed Patents in the Field in the Territory in connection with matters and/or products relating to the Licensed Products, and to
settle  any  claims  in  connection  with  such  enforcement  (a  “Sorrento  Enforcement  Action”).  All  Sorrento  Enforcement  Actions  shall  be
entirely under Sorrento’s direction and control and expense; Sorrento shall have sole responsibility for determining the strategy of Sorrento
Enforcement Actions and filing all papers in connection therewith. Sorrento shall keep PSC reasonably informed of the progress of any such
Sorrento Enforcement Action, and PSC shall have the right to participate in the Sorrento Enforcement Action with counsel of its own choice
at  its  own  expense.  In  any  event,  at  the  request  and  expense  of  Sorrento,  PSC  shall  reasonably  cooperate  with  Sorrento  in  any  Sorrento
Enforcement Action, shall provide Sorrento with such information as Sorrento reasonably requests to facilitate Sorrento’s enforcement of the
Sorrento Enforcement Action, and shall join as a named party in any Sorrento Enforcement Action at the request and expense of Sorrento.
Any recovery received as a result of any Sorrento Enforcement Action shall be used first to reimburse the Parties for the costs and expenses
(including attorneys’ and professional fees) incurred in connection with such Sorrento Enforcement Action (and not previously reimbursed).
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. If, after such reimbursement, any funds remain from such recovery, then such remainder amount of the
recovery shall be retained by Sorrento and treated as Sublicense Revenue received by Sorrento for purposes of calculating the sums owed by
Sorrento to PSC under Section 4.4.

(b)

By PSC. PSC may, solely upon receiving Sorrento’s prior written consent, and at PSC’s sole
expense,  enforce  the  Licensed  Patents  outside  of  the  Field  (a  “PSC  Enforcement  Action”).  PSC  will  have  the  right  to  control  any  PSC
Enforcement  Action,  provided  that  PSC  will  give  Sorrento  an  opportunity  to  review  and  comment  on  the  nature  and  strategy  of  the  PSC
Enforcement  Action  and  consider  in  good  faith  any  comments  from  Sorrento  regarding  the  same.  In  addition,  PSC  shall  keep  Sorrento
reasonably  informed  of  the  progress  of  any  PSC  Enforcement  Action,  and  Sorrento  shall  have  the  right  to  participate  in  any  PSC
Enforcement  Action  with  counsel  of  their  own  choice  at  their  own  expense.  Any  recovery  received  as  a  result  of  any  PSC  Enforcement
Action  shall  be  used  first  to  reimburse  the  Parties  for  the  costs  and  expenses  (including  attorneys’  and  professional  fees)  incurred  in
connection with such PSC Enforcement Action (and not previously reimbursed). 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.  If,  after  such
reimbursement,  any  funds  remain  from  such  recovery,  then  such  remainder  amount  of  the  recovery  shall  be  retained  by  PSC.  For  the
avoidance  of  doubt,  PSC  may  not  threaten  or  bring  any  action  to  enforce  the  Licensed  Patents  without  first  obtaining  Sorrento’s  written
consent to do so. Notwithstanding the foregoing, in no event shall PSC: (i) admit the invalidity of, or after exercising its right to bring and
control an action under this Section 5.3(b), fail to defend the validity of, any Licensed Patents without Sorrento’s prior written consent; or (ii)
settle any PSC Enforcement Action under this Section 5.3(b) without the prior written consent of Sorrento, which consent, in each instance,
may be withheld in Sorrento’s sole discretion.

Section 5.4

Defense of Infringement Claims. In the event that a claim is brought against either Party alleging the
infringement, violation or misappropriation of any Third Party Intellectual Property Right based on the manufacture, use, sale or importation
of the Licensed Materials or Licensed Products, the Parties shall promptly meet to discuss the defense of such claim, and the Parties shall, as
appropriate,  enter  into  a  joint  defense  agreement  with  respect  to  the  common  interest  privilege  protecting  communications  regarding  such
claim in a form reasonably acceptable to the Parties. The Party against

 
 
License Agreement
Page 15 of 23

which such claim is brought shall have the right to control the defense of such claim and shall keep the other Party reasonably informed with
respect thereto.

ARTICLE VI
TERM AND TERMINATION

Section 6.1

Term.  This  Agreement  shall  become  effective  as  of  the  Agreement  Date,  and  will  continue  in  full
force and effect unless and until: (a) mutually terminated in writing by the Parties, or (b) otherwise terminated pursuant to and in accordance
with the terms of this Agreement.

Section 6.2

Termination.

(a)

Termination for Material Breach.

(i)

By Sorrento. If PSC commits a material breach of this Agreement,

Sorrento may provide to PSC a written notice specifying the nature of the breach, requiring PSC to make good or otherwise cure such breach,
and stating its intention to terminate this Agreement if such breach is not cured. If such breach is not cured within ninety (90) days after the
receipt of such notice then, subject to Section 6.2(a)(iii), Sorrento shall be entitled, without prejudice to any of its other rights conferred under
this Agreement, and in addition to any other remedies available to it by law or in equity, to terminate this Agreement by written notice to
PSC.

(ii)

By PSC. If Sorrento commits a material breach of its payment

obligations to PSC under this Agreement, then Sorrento shall have thirty (30) days after receipt of a written notice of the payment breach to
cure that breach; provided, however, regarding the payment of the Upfront Payment per Section 4.1, there is no such cure right and this
Agreement terminates automatically if the Upfront Payment is not paid when due. If Sorrento commits a material breach of any non-payment
obligation, or if Sorrento fails to use Commercially Reasonable Efforts to develop, make, market, and sell a Licensed Product, then PSC may
provide to Sorrento a written notice specifying the nature of the breach or failure, requiring Sorrento to make good or otherwise cure such
breach or failure, and stating its intention to terminate this Agreement if such breach or failure is not cured. If such (i) breach for a non-
payment obligation (excluding a failure to use Commercially Reasonable Efforts) is not cured within ninety (90) days after the receipt of
such breach notice, or (ii) if such failure to use Commercially Reasonable Efforts is not remedied within six (6) months after the receipt of
such failure notice, then, subject to Section 6.2(a)(iii), PSC shall be entitled, without prejudice to any of its other rights conferred under this
Agreement, and in addition to any other remedies available to it by law or in equity, to terminate this Agreement by written notice to
Sorrento. For the avoidance of doubt, PSC shall not be permitted to terminate or rescind this Agreement as a result of any circumstances that
are not expressly addressed in this Section 6.2(a)(ii) or Section 6.2(c) below. For clarity, if PSC terminates this Agreement for failure of
Sorrento to use Commercially Reasonable Efforts, Sorrento shall not have any liability for any damages from such breach.

(iii)

If the alleged breaching Party disputes in good faith the existence or
materiality of a breach specified in a notice provided by the other Party in accordance with Section 6.2(a) (i) or Section 6.2(a)(ii), and such
alleged breaching Party provides the other Party notice of such dispute within fifteen (15) days of the date of the notice provided by the other
Party in accordance with Section 6.2(a) and, with respect to payment, such alleged breaching Party pays any portion of such payment not in
dispute, then the non-breaching Party will not have the right to terminate this Agreement under Section 6.2(a) unless and until: (1) the
arbitrators, in accordance with Section 6.2(a)(iii) and Section 6.2(a)(iv), have determined that the alleged breaching Party has materially
breached this Agreement (an “Arbitral Decision”) and such breach would entitle the other Party to terminate this Agreement, and (2) the
alleged breaching Party has failed to cure such breach within ninety (90) days following such Arbitral Decision.

 
 
License Agreement
Page 16 of 23

The Arbitral Decision will include a description of what is required to cure such breach. If the arbitrators determine that a Party should be
regarded as the prevailing Party, then such prevailing Party in such arbitration shall be reimbursed by the other Party for all of such prevailing
Party’s expenses related to such arbitration proceeding. It is understood and agreed that during the pendency of such dispute, all of the terms
and conditions of this Agreement will remain in effect.

(iv)

The Arbitral Decision shall be reached, and the arbitration proceeding
shall be conducted, in accordance with the simplified process procedures of the American Arbitration Association. The number of arbitrators
shall be three, one of whom shall be appointed by each of the parties and the third of whom shall be selected by mutual agreement of the co-
arbitrators with the input of the parties, within thirty (30) days of the selection of the second arbitrator and thereafter by the American
Arbitration Association. The seat of the arbitration will be San Diego, California. The arbitration award rendered by the arbitrators shall be
final and binding on the parties. Judgment on the award may be entered in any court having jurisdiction thereof.

As to termination by PSC, the Parties agree that termination pursuant to
Section 6.2(a)(ii) is a remedy to be invoked only if the breach is not adequately remedied within 6 months through a combination of specific
performance and the payment of money damages.

(v)

(b)

Termination for Convenience by Sorrento. Sorrento may terminate this Agreement for no

reason or for any reasons upon three (3) months’ written notice to PSC

(c)

Termination Due to Abandonment of the Licensed Products by Sorrento. If Sorrento is not
expending any efforts to develop or commercialize any Licensed Products (other than due to a force majeure) and Sorrento does not have
good faith plans to do so in the near-future, then PSC may provide a notice of abandonment to Sorrento and, if Sorrento has not resumed
good faith Commercially Reasonable Efforts for the development or commercialization of a Licensed Product within one hundred and eighty
(180) days from the date of a rightful notice of abandonment, then PSC may terminate this Agreement by providing a written notice of
termination to Sorrento, which termination will be effective immediately as of the date of such notice.

All remedies set forth herein shall be cumulative and in addition to any other remedies such Party may have at law or in equity.

Section 6.3

Effects of Termination or Expiration.

(a)

By  PSC  for  Cause;  or  Abandonment  by  Sorrento;  or  by  Sorrento  without  Cause.
Termination of this Agreement (i) by PSC under Section 6.2(a)(ii)  or  Section 6.2(c)  or  (ii)  by  Sorrento  under  Section 6.2(b)  will  result  in
termination of Sorrento’s license rights under Section 2.1; provided, however, that, unless terminated under Section 6.2(c), Sorrento and its
Sublicensees may, for a period not to exceed one (1) year, finish manufacturing and selling any inventories of Licensed Products existing
(including in process inventories or inventories subject to contractual manufacturing or purchase commitments) on the date of termination,
provided  Sorrento  shall  continue  to  fulfill  all  of  its  respective  payment  obligations  under  Article  4  of  this  Agreement.      For  clarity,  such
termination will result in (i) the termination of all license rights, and (ii) all data, materials, and PSC Confidential Information previously
provided by PSC to Sorrento shall be returned to PSC following such one (1) year wind down period.

By Sorrento for Cause. Termination of this Agreement by Sorrento under Section 6.2(a) for
material  breach  of  this  Agreement  by  PSC  will  result  in  the  licenses  in  Section  2.1  becoming  irrevocable  and  all  further  Royalties  and
Milestone Payments will be reduced by […***…] percent ([…***…]%).

(b)

 
 
License Agreement
Page 17 of 23

Expiration. Upon expiration of this Agreement with respect to a particular country pursuant
to  Section  6.1  all  rights  and  licenses  granted  to  Sorrento  under  this  Agreement  with  respect  to  such  country  will  become  fully  paid,
irrevocable, and royalty free.

(c)

(d)

 Survival. The rights and obligations of the Parties set forth in the following provisions shall

Binding Term Sheet

for the Acquisition of ACEA Therapeutics, Inc. by

Sorrento Therapeutics, Inc.
October 14, 2020

Exhibit 10.23

This Term Sheet (“Term Sheet”) sets forth certain non-binding understandings and certain binding agreements regarding the proposed
acquisition  of  ACEA  Therapeutics,  Inc.  (“ACEA”)  by  Sorrento  Therapeutics,  Inc.  (“Sorrento”).    Collectively  ACEA  and  Sorrento  are
“Parties”.    

As promptly as practicable following the acceptance, execution and delivery of this Term Sheet by Sorrento, the Parties would expect

to commence negotiations to enter into a definitive agreement regarding the Transaction (as defined below) (the “Definitive Agreement”).

Upon  execution  by  Sorrento  of  this  Term  Sheet,  the  Sections  numbered  1  and  4  through  6  of  this  Term  Sheet  (collectively,  the
“Nonbinding Provisions”) reflect the Parties’ mutual understanding of the matters described in such sections.  Each Party acknowledges that
the  Nonbinding  Provisions  are  not  intended  to,  and  do  not,  create  or  constitute  any  legally  binding  obligation  between  Sorrento  and
ACEA.  The Parties do not intend to be bound by any agreement, and neither Sorrento nor ACEA shall have any liability to the other Party
with  respect  to  the  Nonbinding  Provisions,  until  the  Definitive  Agreement  is  executed  and  delivered  by  and  between  all  Parties.    Upon
execution  by  Sorrento  of  this  Term  Sheet,  the  Sections  numbered  2,  3  and  7  through  15  of  this  Term  Sheet  (collectively,  the  “Binding
Provisions”) will constitute the legally binding and enforceable agreements of Sorrento and ACEA in recognition of the significant costs to
be borne by each in pursuing the Transaction and further in consideration of their mutual undertakings as to the matters described herein.

Section

1.   Acquisition

Sorrento  would  acquire  100%  of  the  outstanding  equity  securities  of  ACEA  by  means  of  a  reverse
triangular  merger  in  which  a  newly-formed  subsidiary  of  Sorrento  would  be  merged  with  and  into
ACEA  (the  “Transaction”).  As  a  result  of  the  Transaction,  ACEA  would  become  a  wholly  owned
subsidiary of Sorrento.  

The Parties recognize the structure of the Transaction is subject to continuing review and analysis and
that it may be necessary or appropriate to change the structure as a result of tax, accounting or other
considerations, as may be mutually agreed.

 
 
 
 
 
Section

2.   Merger Consideration The  consideration  payable  by  Sorrento  shall  be  comprised  of  a  $38  million  upfront  payment  upon
completion of the Transaction, License Agreement Payments (as defined below), Royalty Payments (as
defined below) and $265 million in additional milestone-based contingent value rights.

Sorrento shall acquire all outstanding equity interests of ACEA on a fully-diluted basis.

For the purposes of this Term Sheet, fully-diluted basis means all outstanding shares of common and
preferred stock of ACEA and assuming the exercise of all options, warrants and rights to exercise or
convert outstanding securities of ACEA, if any, at the effective

time of the proposed merger (whether or  not then exercisable or vested).  All such shares, options,
warrants, and other rights shall be canceled and converted into the right to receive a portion of the
merger consideration, less the exercise price thereof (if applicable).  

Except as otherwise provided herein, Sorrento may, in its sole and absolute discretion, elect to make any
payments referenced herein, including the Upfront Payments (as defined below) and settlement of any of
the  CVRs  (as  defined  below),  in  either  cash  or  shares  of  Sorrento  common  stock  or  a  combination  of
cash and shares of Sorrento common stock, based on an exchange ratio to be agreed by the Parties.

If Sorrento elects to satisfy any such payments, including the Upfront Payments and settlement of any of
the CVRs, in shares of Sorrento common stock, then following any such issuance, Sorrento shall file a
resale registration statement with the Securities and Exchange Commission to register for resale such
shares of Sorrento common stock.  In the event Sorrento satisfies all or a portion of the foregoing
consideration payments through the delivery to ACEA’s equityholders of shares of Sorrento common
stock (the “Consideration Shares”), the price per share of the Consideration Shares (the “Consideration
Per-Share Price”) used for calculating the number of the Consideration Shares to be issued to ACEA’s
equityholders shall be the volume weighted average price of the shares of common stock of Sorrento
traded on The NASDAQ Stock Market LLC for ten (10) trading days ending on the date that is three (3)
trading days prior to the applicable date of issuance. If the Consideration Per-Share Price is greater than
the closing price per share of Sorrento common stock, as reported on The Nasdaq Stock Market LLC on
the date that is six (6) months after the date of issuance of Consideration Shares (the “Consideration
Payment 6-Month Price”), as applicable, Sorrento shall reimburse ACEA’s equityholders for the
difference in value through (a) the payment of cash, (b) the delivery of additional shares of Sorrento
common stock valued at the Consideration Payment 6-Month Price or (c) a combination of the
foregoing.

Upfront Payment

Sorrento  shall  make  the  following  payments  within  ten  (10)  days  of  closing  the  Transaction
(collectively, the “Upfront Payments”):

(1)$36  million,  in  respect  of  existing  shareholder  loans  to  be  paid  directly  to  the  bridge  lenders,

which shall be paid in shares of Sorrento common stock; and

(2)the remainder of the consideration shall be payable to ACEA’s  equityholders.

of ACEA 5% of the annual Net Sales (to be defined in the Definitive Agreement in a manner consistent
in all material respects with such term as defined in the License Agreement) of all products of Sorrento
incorporating  Abivertinib  (China),  AC0058  (worldwide)  and  AC0939  (worldwide)  (such  products,
collectively,  the  “Royalty  Bearing  Products”  and  such  payments,  the  “Royalty  Payments”).    The
Definitive  Agreement  will  include  ordinary  and  customary  royalty  step  down  and  royalty  stacking

Sorrento prior to the signing of a Definitive Agreement, shall enter into non-competition agreements to
be effective as of the effective time of the merger.

8.   Confidentiality;

Publicity

ACEA’s Chief Executive Officer’s future arrangement and compensation with Sorrento will be
transparent to ACEA’s Board of Directors and stockholders.

Each Party recognizes that this Term Sheet is confidential and that disclosure of the provisions contained
herein would cause irreparable harm to the other Party. Accordingly, each Party agrees that the terms,
conditions and contents of this Term Sheet will be kept confidential and will not be published or
disclosed, other than to a Party’s advisors and consultants who have a need to know and who are subject
to obligations of confidentiality, or as may be required by applicable law, rule or regulation.

The Parties have entered into a Mutual Confidentiality Disclosure Agreement dated February 24,
2020.  Each Party acknowledges and agrees that such agreement shall remain in full force and effect
following execution of this Term Sheet and hereby ratifies and confirms their obligations thereunder.

Neither party will make any public disclosure related to this Term Sheet without the prior written
consent of the other party, except that Sorrento shall be permitted (without the prior written consent of
ACEA), to make such public disclosure, announcements and filings as may be required by applicable
law or by applicable rules of any stock exchange on which Sorrento lists or trades securities.

9.   Costs

10.   Exclusivity

11.   Termination

Each of Sorrento and ACEA will pay its own direct costs and expenses, including the fees of attorneys,
accountants, investment bankers and other advisors, incurred at any time in

connection with the Transaction; provided, however, that any fees and expenses incurred by the Parties in
submitting any regulatory filings shall be borne one-half by Sorrento and one-half by ACEA.

For the period commencing on the date on which both Parties have executed this Term Sheet (the
“Effective Date”) and ending at 5:00 p.m. San Diego, California local time on the date that is 90 days
from the Effective Date (the “Exclusivity Period”), ACEA (including its directors, officers, managers,
employees and professional advisors) will negotiate exclusively and in good faith with Sorrento with
respect to entering into the Definitive Agreement and the other matters contemplated by this Term
Sheet.  During the Exclusivity Period, ACEA (including its directors, officers, managers, employees and
professional advisors) will not, directly or indirectly, solicit, initiate, seek, entertain, knowingly
encourage, knowingly facilitate or support any inquiry, proposal or offer from, furnish any information
to, or participate in any discussions or negotiations with, any person or entity other than Sorrento and its
representatives with respect to any sale or other disposition of any equity securities of ACEA, or any
merger, consolidation, business combination or similar transaction, any sale, license, lease or other
disposition of all or substantially all of the assets of ACEA (a “Competing Proposal”), or enter into any
agreement with any such other person or entity concerning such a transaction.  ACEA further covenants
and agrees to terminate any such discussions or negotiations in respect of a Competing Proposal in
progress as of the Effective Date.  If ACEA (including any of its directors, officers, managers,
employees or professional advisors) receives an offer or expression of interest to make an offer for a
Competing Proposal from a third party, ACEA will promptly (but in any event within 24 hours) notify
Sorrento in writing of the terms and conditions of such offer and the identity of the person or entity
making such offer.

This Term Sheet, including the Binding Provisions, (i) will terminate, without further action by either
Sorrento or ACEA, at 5:00 p.m. San Diego, California local time on the last day of the Exclusivity
Period, if the Definitive Agreement has not been executed by that date, and (ii) may be terminated by
Sorrento upon written notice delivered to ACEA if Sorrento determines that it does not desire in its sole
discretion to proceed with the Transaction.  Upon termination, the Parties shall have no further
obligations hereunder, except that the provisions of Sections 8, 9 and 14 shall survive any such
termination.

12.   Amendment

Any waiver, amendment, modification or supplement of or to any term or condition of the Binding
Provisions shall be effective only if in writing and signed by Sorrento and ACEA, and the Parties hereby
waive the right to amend the provisions of this Section 12 orally.

13.   Non-Assignment

This Term Sheet is not, and the Definitive Agreement will not be, assignable by Sorrento or ACEA
without the prior written consent of the other Party.

14.   Choice of Law; Venue The Binding Provisions will be construed and enforced in accordance with the laws of the State of

Delaware without regard to conflicts of law principles.  Any action or proceeding seeking to enforce any
provision of, or based on any right arising out of, this Term Sheet may be brought against any Party in
the federal and state courts of the State of Delaware and each Party consents to the jurisdiction of such
courts in any such action or proceeding and waives any objection to venue laid therein.  Process in any
action or proceeding referred to in the preceding sentence may be served on any Party anywhere in the
world.

15.   Counterparts

This Term Sheet may be executed in one or more counterparts, each of which will be deemed to be an
original and all of which, when taken together, will be deemed to constitute one and the same document.

Note:  Solely  with  respect  to  the  Milestone  Payments,  Sorrento  will  pay  ACEA’s  equityholders  all  such  payments  due,  even  if
completed  clinical  trials  are  not  conducted  because  of  the  purchased  assets  receiving  a  Fast  Track  or  Breakthrough  Therapy
designation, and/or receiving Accelerated Approval by the U.S. Food and Drug Administration or the equivalent  governing body in
the applicable jurisdiction.
