Item 1. Business.

Overview

We are a clinical-stage biopharmaceutical company focused on the development and commercialization of innovative therapies for the treatment of

liver and cardio-metabolic diseases. Our lead product candidate, BIO89-100, a specifically engineered glycoPEGylated analog of fibroblast growth factor
21 (“ FGF21”), is currently being developed for the treatment of nonalcoholic steatohepatitis (“NASH”). NASH is a severe form of nonalcoholic fatty liver
disease (“NAFLD”), characterized by inflammation and fibrosis in the liver that can progress to cirrhosis, liver failure, hepatocellular carcinoma (“HCC”)
and death. There are currently no approved products for the treatment of NASH. FGF21 is a clinically-validated mechanism that has been shown in humans
to reduce steatosis and address cardio-metabolic dysregulation. We believe BIO89-100 may be a differentiated FGF21 therapy based on its robust and
durable biological effects and a favorable tolerability profile, as well its potential for a longer dosing interval. Combining these characteristics with the
ability to address the key liver pathologies in NASH, as well as the underlying metabolic dysregulation in NASH patients, BIO89-100 has the potential to
become a mainstay of NASH therapy. We successfully completed a Phase 1a, first-in-human, SAD clinical trial with 58 healthy volunteers. The magnitude
and significance of BIO89-100’s biological effects after a single dose on lipid parameters were robust and durable. In July 2019, we initiated our proof of
concept (“POC”) Phase 1b/2a clinical trial in patients with NASH or patients with NAFLD and a high risk of NASH and we expect to report topline data in
the second half of 2020. We also intend to develop BIO89-100 for the treatment of severe hypertriglyceridemia (“SHTG”), a condition identified by
severely elevated levels of triglycerides (greater than or equal to 500 mg/dL), which is associated with an increased risk of NASH, cardiovascular events
and acute pancreatitis. We expect to initiate our Phase 2 trial in SHTG patients in the first half of 2020 in order to evaluate the ability of BIO89-100 to
reduce fasting plasma triglyceride levels compared to baseline levels and to report topline data in the first half of 2021. Based on the U.S. Food and Drug
Administration (“FDA”) guidance for the development of SHTG treatments, as well as the regulatory path followed by other companies that have
successfully developed SHTG therapies, we believe that a combination of smaller clinical trials and shorter development timelines could mean that SHTG
potentially represents a quicker path to market for BIO89-100. We believe BIO89-100 has the potential to address multiple drivers underlying metabolic
dysregulation, which would make it an ideal candidate for selected liver and cardio-metabolic diseases.

The prevalence of NAFLD, which affects approximately 25% of the global population, and NASH, which develops in approximately 20% to 25%
of NAFLD patients, is growing and is driven primarily by the worldwide obesity epidemic. NAFLD and NASH patients have an excessive accumulation of
fat in the liver resulting primarily from a caloric intake above and beyond energy needs. In NAFLD patients, this abnormal liver fat contributes to the
progression to NASH, a liver necro-inflammatory state, that can lead to scarring, also known as fibrosis, and, for some, can progress to cirrhosis and liver
failure. The critical pathophysiologic mechanisms underlying the development and progression of NASH include reduced ability to handle lipids, increased
insulin resistance, injury to hepatocytes and liver fibrosis in response to hepatocyte injury. Patients with NASH frequently have other significant metabolic
co-morbidities such as obesity, hyperglycemia, dyslipidemia and systemic hypertension (a constellation of which is commonly referred to as metabolic
syndrome) and these further contribute to the risk of cardiovascular disease. The number of NASH cases in the United States is projected to expand from
16.5 million in 2015 to 27 million in 2030, with similar prevalence growth expected in Europe. Diet and exercise are currently the standard of care for
NAFLD and NASH, but adherence to this treatment regimen is poor and there remains a high unmet need in the treatment of NASH.

BIO89-100 is a specifically engineered FGF21 analog that we believe has the potential to address the critical pathophysiologic mechanisms
underlying NASH. FGF21 is a metabolic hormone that regulates energy expenditure and glucose and lipid metabolism. FGF21 has been clinically shown to
reduce steatosis in the liver. It is also thought to exert effects on liver fibrosis by improving metabolic regulation, which reduces ongoing liver injury thus
giving the liver time to heal. FGF21 also generates an on-target effect to increase adiponectin, a hormone released from adipose tissue that, among other
functions, can suppress development and progression of hepatic fibrosis. However, FGF21 in its native form suffers from a short half-life and a tendency to
aggregate in solution, both of which impact its suitability as a viable drug. To address these challenges, we have specifically engineered BIO89-100 to
maintain the clinical benefits of FGF21, while extending half-life in vivo, protecting against proteolysis, reducing renal clearance, minimizing
susceptibility to aggregate in solution and optimizing potency.

BIO89-100 has been evaluated in seven animal studies of NASH, diabetes and obesity, including studies in mice and non-human primates. Each
study was customized to assess endpoints relevant to liver and metabolic diseases and conducted according to standard practices at experienced contract
research organizations (“CROs”). In these preclinical studies, consistent beneficial effects across a range of endpoints were observed, including
improvements in hepatic steatosis, injury and fibrosis in a diet-induced NASH study of 50 mice (see “BIO89-100—Results of DIN Mouse Studies” Figure
11 which illustrates that statistically significant mean changes with respect to hepatic steatosis and fibrosis were each observed and Figure 12 which
illustrates that statistically significant mean changes with respect to injury were observed) and improved glycemic control and lipid handling in a study of
24 spontaneously diabetic obese cynomolgus monkeys with elevated triglycerides (see “BIO89-100—Results of Spontaneously Diabetic Obese
Cynomolgus Monkey Studies” Figures 20 and 21, respectively, which illustrate that statistically significant mean changes with respect to glycemic control
and lipid handling were each observed). We believe this demonstrates BIO89-100’s potential to simultaneously address the multiple drivers of NASH
pathogenesis. The histological endpoints assessed in these preclinical studies, NAFLD activity score (“NAS”) and fibrosis score, mirror the endpoints we
expect to assess in our clinical development. In addition, treatment with BIO89-100 in animal models demonstrated consistent reductions in body weight.

In May 2019, we announced positive topline data from our Phase 1a, first-in-human, SAD clinical trial of BIO89-100 in 58 healthy volunteers. In
this SAD study, BIO89-100 demonstrated a favorable tolerability profile in the 43 volunteers who received BIO89-100 with a half-life of 55 to 100 hours.
At single doses of 9.1 mg and higher, BIO89-100 demonstrated significant improvements in key lipid parameters measured at Day 8 and Day 15 after
dosing on Day 1. The mean changes versus baseline include reductions in triglycerides (up to 51%) and LDL-C (up to 37%) and increase in HDL-C (up to
36%) despite the baseline values being in the normal range. As compared to placebo treatment, these mean changes were all statistically significant (p <
0.001). BIO89-100 demonstrated rapid (beginning from Day 2), sustained and durable improvements in lipid parameters for two weeks or more after single
dose administration. Based on these findings and results from our animal studies, we believe such a lengthy duration of effect may confer longer dosing
intervals to BIO89-100.

In the second quarter of 2020, we expect to complete patient enrollment in our POC Phase 1b/2a trial with 83 total patients randomized to receive

once weekly or once every two weeks subcutaneous dosing of either BIO89-100 or placebo, in each case, for up to 12 weeks.

This trial is designed to assess the safety, tolerability and PK properties of BIO89-100, as well as changes in liver steatosis and key biomarker

assessments.

We also intend to develop BIO89-100 for the treatment of SHTG, a condition identified by severely elevated levels of triglycerides (greater than or
equal to 500 mg/dL) and which is associated with an increased risk of NASH, cardiovascular events and acute pancreatitis. SHTG accounts for up to 10%
of all acute pancreatitis episodes. It is estimated that there are 2.5 million to 4 million patients in the United States with TG ≥ 500 mg/dL and up to 50% of
SHTG patients treated with certain approved drugs are refractory to current standard of care. In a study of 24 diabetic obese cynomolgus monkeys with
elevated triglycerides, BIO89-100 showed significant effects on triglycerides at doses as low as 0.1 mg/kg/week, with a 78% reduction from baseline
(range of 52% reduction to 94% reduction) observed at the highest dose level of 1.0 mg/kg/week on Day 56. In our Phase 1a SAD study, BIO89-100
showed a significant reduction in triglycerides of up to 51% after a single dose in healthy volunteers. While currently approved SHTG therapies decrease
TG levels, they generally do not have broader metabolic benefits. To the extent that we are able to show in subsequent human clinical trials that BIO89-100
significantly decreases both TG and LDL-C levels and improves other metabolic parameters, we believe that BIO89-100 could be a differentiated therapy
in this indication. We expect to initiate our Phase 2 trial in SHTG patients in the first half of 2020 in order to evaluate the ability of BIO89-100 to reduce
fasting plasma triglyceride levels compared to baseline levels and to report topline data in the first half of 2021.

We retain exclusive worldwide rights to BIO89-100. BIO89-100 is protected by a family of issued patents with claims directed to composition of

matter and methods of use. The first of our patents for BIO89-100 are projected to expire in the United States in 2028, with the final composition-of-matter
patent projected to expire in the United States in 2038, in each case, without patent term extensions. Because BIO89-100 is a biologic drug, marketing
approval is also expected to provide 12 years of market exclusivity in the United States from the approval date of a BLA. We license the patents and know-
how related to the glycoPEGylation technology for use in the research, development, manufacture and commercialization of BIO89-100 from Teva and
ratiopharm GmbH (“ratiopharm”).

Strategy

Our goal is to become a leading biopharmaceutical company focused on the development and commercialization of innovative therapies for the

treatment of liver and cardio-metabolic diseases. The key components of our strategy are to:

•

•

•

•

•

Rapidly advance BIO89-100 through clinical development for the treatment of NASH. We believe BIO89-100 may be a differentiated
FGF21 therapy based on its robust and durable biological effects and a favorable tolerability profile, as its potential for a longer dosing
interval, and is well positioned to address the complex pathophysiology of NASH. In the second quarter of 2020, we expect to complete
patient enrollment in our POC Phase 1b/2a clinical trial to evaluate the safety and efficacy of BIO89-100. We believe that our trial design
and the use of well-established surrogate clinical endpoints can contribute meaningfully to the rapid advancement of BIO89-100 through its
clinical development. With potential for BIO89-100 to be established as a mainstay monotherapy for NASH, we continue to explore
opportunities to combine BIO89-100 with products targeting other pathways within NASH for possible development as a combination
therapy.

Expand the breadth of indications for BIO89-100 with an initial focus on SHTG. While we are focused on becoming a leader in the
treatment of NASH, the mechanism of action of our FGF21 analog supports evaluation across a spectrum of liver and cardio-metabolic
diseases. We believe BIO89-100’s mechanism and potentially robust and durable biological effects and favorable tolerability profile, as
well as its potential for a longer dosing interval make it an ideal candidate for selected liver and cardio-metabolic diseases. We intend to
develop BIO89-100 for the treatment of SHTG. Based on FDA guidance for the development of SHTG treatments, as well as the
regulatory path followed by other companies that have successfully developed SHTG therapies, we believe that a combination of smaller
clinical trials and shorter development timelines could mean that SHTG potentially represents a quicker path to market for BIO89-100.

Scale-up and optimize the manufacturing of BIO89-100. We currently use an external contract manufacturing organization (“CMO”) to
manufacture BIO89-100 for our ongoing and planned clinical trials. While these trials are ongoing, we plan to work with our CMO to
optimize and scale-up the manufacturing process for BIO89-100 to support the increased production that will be needed for later-stage
clinical trials and commercialization, if BIO89-100 is approved.

Establish a commercial infrastructure in key geographies. We have worldwide rights to BIO89-100 and intend to develop the sales
infrastructure required for commercialization in the United States. We also plan to evaluate options, including strategic collaborations, for
commercializing BIO89-100, if approved, in other key markets, such as Europe and China.

Construct a diversified multi-asset pipeline of novel therapies. We intend to employ a value-driven strategy to identify, acquire, develop
and commercialize product candidates for liver and cardio-metabolic diseases. We intend to focus on product candidates that we believe
have attractive profiles in early clinical testing, address a clear unmet medical need and can advance quickly and efficiently into late-stage
development.

Our Focus on Liver and Cardio-Metabolic Disease

We are focused on developing and commercializing therapeutic interventions that have a clinically meaningful impact on patients with liver and

cardio-metabolic diseases. These diseases, including NASH and SHTG, represent leading global causes of morbidity and mortality. Despite a wave of
public health campaigns to promote better diet and exercise habits and a range of treatment options available for many of these diseases, there is a
significant unmet medical need for more effective therapies to improve patient outcomes and reduce the burden on global healthcare systems.

We are currently developing our lead product candidate, BIO89-100, a specifically engineered glycoPEGylated analog of FGF21, for the treatment

of NASH. We believe BIO89-100 is an ideal candidate for the treatment of NASH based on:

•

•

•

•

its ability to address the key liver pathologies in NASH;

its ability to address the underlying metabolic dysregulation in NASH patients;

its balance of its robust and durable biological effects and favorable tolerability profile; and

its potential for a longer dosing interval.

Given the potential of BIO89-100 to meaningfully reduce triglycerides, we also intend to develop BIO89-100 for the treatment of SHTG. There is

regulatory precedence for the approval of a therapy for the treatment of patients with SHTG in the United States and the reduction in triglycerides from
baseline is recognized by the FDA as the primary endpoint for full approval. Based on FDA guidance for the development of SHTG treatments, as well as
the regulatory path followed by other companies that have successfully developed SHTG therapies, we believe that a combination of smaller clinical trials
and shorter development timelines could mean that SHTG potentially represents a quicker path to market for BIO89-100.

NASH Overview

NAFLD is emerging as the most common chronic liver disorder, driven primarily by the global obesity epidemic. NAFLD affects approximately

25% of the population globally and is often referred to as the hepatic manifestation of metabolic syndrome. Patients with NAFLD have an excessive
accumulation of fat in the liver resulting from a caloric intake above and beyond energy needs. This abnormal fat in the liver contributes to the progression
of NAFLD to NASH, a necro-inflammatory state in the liver that ultimately leads to scarring, also known as fibrosis; and for certain patients, progression
to cirrhosis and liver failure.

Patients with NASH exhibit suboptimal lipid handling, increased insulin resistance, caloric overload and inadequate fat burning, all of which

contribute to the increased risk of cardiovascular disease. Due to an increase in obesity and Type 2 diabetes, which predispose individuals to more
significant liver disease, the number of NASH cases in the United States is projected to expand from 16.5 million in 2015 to 27 million in 2030.

Currently, there are no approved products for the treatment of NASH and diet and exercise is established as the standard of care.

Disease Overview

NAFLD is a condition of excess fat accumulation, or steatosis, of more than 5% in liver cells, also known as hepatocytes. NASH, a severe form of

NAFLD, is characterized histologically by the additional presence of inflammation and hepatocellular injury such as visible ballooning and has a
significantly worse prognosis, with the potential to progress to liver fibrosis, cirrhosis or HCC. Steatohepatitis is a key catalyst in fibrosis development, and
there is a substantial collinearity between the presence of NASH and fibrosis severity. While NAFLD has historically been viewed as benign in terms of
liver-related outcomes, recent studies have challenged this notion since patients with NAFLD may develop NASH and fibrosis over time.

6

 
 
 
 
 
Figure 1 below shows the increase in prevalence liver-related mortality rates by fibrosis stage.

Figure 1: Prevalence and Liver-Related Mortality Rate by Fibrosis Stage

It is estimated that 20% to 25% of NAFLD patients progress to NASH. Of those with NASH, cirrhosis develops in approximately 20% and 45% of

patients and in some cases, cirrhosis progresses to decompensated cirrhosis, which results in permanent liver damage that can lead to liver failure. In
addition, it is estimated that 8% of patients with advanced fibrosis will develop HCC.

There is a high unmet need in the treatment of NASH, and there are currently no approved therapies. In the United States, the number of NASH

cases is projected to expand from 16.5 million in 2015 (5.1% of the population) to 27 million in 2030. The expected lifetime economic burden of all
patients with NASH in the United States in 2017 is estimated at $223 billion. NASH is currently the second leading cause of liver transplants behind
hepatitis C, and is expected to become the leading cause of liver transplants by 2020.

Additionally, multiple epidemiological studies have linked NAFLD to increased cardiovascular disease, concluding that the majority of deaths
among NAFLD patients are attributable to cardiovascular disease. As a result, we believe it is important that new therapeutics options for NASH also
address the underlying cardiovascular and metabolic dysregulations in these patients.

Etiology

Understanding of the pathophysiologic mechanisms that lead to NASH has evolved in recent years. Excessive caloric overload, metabolic
dysregulation, cardio-metabolic co-morbidities and genetic risk factors increase the likelihood of developing NASH, with a multitude of potential
mechanistic contributors to pathophysiology. In NASH, the liver’s capacity to handle the primary metabolic energy substrates, carbohydrates and fatty
acids, is overwhelmed. This occurs when there is an excess of free fatty acids deposited in the liver or their disposal from the liver is impaired. The
accumulation of surplus free fatty acids leads to the formation of toxic lipid species. These toxic lipids then induce endoplasmic reticulum stress, oxidative
stress and an inflammatory response, which can result in hepatocellular injury and death. This may lead to fibrosis and genomic instability, which may
worsen over time to cirrhosis and HCC, respectively.

7

 
 
 
As shown in Figure 2 below, the critical pathophysiologic mechanisms underlying development and progression of NASH include (1) reduced

ability to handle lipids, (2) increased insulin resistance, (3) injury to hepatocytes and (4) development and progression of liver fibrosis in response to
hepatocyte injury.

Figure 2: Mechanisms Underlying Development and Progression of NASH

Reduced Ability to Handle Lipids

Excess consumption of calories, poor diet and a sedentary lifestyle, each often associated with obesity, can burden the body with a surplus of

carbohydrates and lipids. This burden can be progressively more difficult for the liver to handle thereby resulting in steatosis in the liver. The problem is
compounded further as insulin resistance develops.

Free fatty acids (“FFA”) accumulate in the liver primarily from three sources, namely, through (1) the transfer from peripheral adipose tissues

where triglycerides are mobilized, (2) de-novo lipogenesis (“DNL”), and (3) direct dietary intake. The FFA that lead to NASH are believed to arise
primarily from the peripheral tissue pool and secondarily through DNL. The increase in the influx of FFA to the liver from the peripheral tissues is driven
by excessive caloric intake greater than the body’s demand and increased insulin resistance resulting in deposition of fat to the liver for processing. DNL is
a distinct process in the liver by which hepatocytes convert excess carbohydrates, especially fructose, to fatty acids.

The three main fates of fatty acids in the liver are (1) mitochondrial beta-oxidation (to release ATP, or energy), (2) re-esterification to form

triglyceride, which can then be exported into the blood as very low density lipoproteins, or (3) stored in lipid droplets, resulting in liver steatosis and
ultimately NASH. Adiponectin, a hormone derived from adipose tissue, appears to have a pivotal role in improving fatty acid oxidation and decreasing
fatty acid synthesis, components of lipid handling.

An increase in cholesterol accumulation in the liver can also contribute to NASH, though its role is not as clearly defined as in the case of

triglycerides. The dysregulation of the cholesterol pathway can result in an increase in the cholesterol levels in the liver. The increased cholesterol can
accumulate in the liver cell membranes and activate Kupffer cells (activated stellate macrophages), thereby triggering inflammatory pathways and resulting
in the progression of NASH.

8

 
 
 
Increased Insulin Resistance

Insulin resistance, which typically develops in obese individuals, is considered to be a fundamental underlying mechanism in the majority of

NASH patients. Fatty acids are primarily delivered to the liver from blood following lipolysis of triglycerides in adipose tissue, a process that is regulated
by the actions of insulin on adipocytes. Insulin resistance in adipose tissue manifests as dysregulated lipolysis resulting in excessive delivery of FFA to the
liver. The liver tries to cope with the large influx of FFA; however, the build-up of metabolic intermediates interferes with signaling, resulting in hepatic
insulin resistance and the inability of the liver to process this excess FFA influx. The state of hepatic insulin resistance further exacerbates the problem by
triggering DNL and the build-up of excess fat in the liver.

Injury to Hepatocytes

When the disposal of fatty acids through beta-oxidation or the formation of triglycerides is chronically overwhelmed, fatty acids can form lipotoxic
species that lead to stress on the endoplasmic reticulum, oxidative stress and inflammation, all of which are pivotal processes in the development of NASH.
Liver inflammation may be an important link between the initial metabolic stress and subsequent hepatocyte death and stimulation of fibrogenesis in
NASH by promotion of the expression of pro-inflammatory cytokines and of apoptosis (cell death). These processes are core to the steatohepatitis that
gives NASH its name. For example, hepatocyte apoptosis results in the ballooning of cells, a classic pathological feature of NASH. While hepatocytes are
the primary and major target of toxic lipids, other cells such as Kupffer cells and hepatic stellate cells are also affected by lipotoxicity and contribute to the
development of NASH pathology.

Additional factors, including dysregulation of cytokines and adipokines, energy depletion, anti-oxidant deficiencies, products of the gut

microbiome and iron load may modulate hepatocyte vulnerability to the development of lipotoxic stress, injury and inflammation.

Development and Progression of Liver Fibrosis in Response to Hepatocyte Injury

Signaling from stressed or injured hepatocytes and Kupffer cells leads to activation of quiescent hepatic stellate cells. Upon activation, hepatic

stellate cells release collagen and other factors. When the production of collagen and matrix proteins is faster than their degradation, accumulation of these
proteins in the extracellular matrix can lead to progressive fibrosis. As the lipotoxicity and inflammation continue to damage the liver, the hepatic stellate
cells continue to be activated resulting in greater collagen deposition that ultimately leads to fibrosis and cirrhosis.

Co-morbidities Associated with NASH

Patients with NASH frequently have other significant co-morbidities—hypertriglyceridemia, obesity, hyperlipidemia/dyslipidemia, hyperglycemia
(including Type 2 diabetes) and systemic hypertension, a constellation of which is commonly referred to as metabolic syndrome—which also increase the
risk of developing cardiovascular disease. Figure 3 below shows certain co-morbidities associated with NASH.

The association between NASH and features of metabolic syndrome appears to be bidirectional.

Metabolic syndrome increases the risk of NASH and NASH may also exacerbate several features and co-morbidities of metabolic syndrome. Type
2 diabetes, hypertriglyceridemia, obesity and other features of metabolic syndrome have all been shown to be associated with an increased risk for NASH
and advanced liver fibrosis. In addition, it is estimated that approximately 30% of obese patients and approximately 30% of patients with Type 2 diabetes
have NASH.

In addition, NASH was found to independently increase the risk of non-liver-related adverse outcomes, including cardiovascular risk and

malignancy. Multiple epidemiological studies have linked NASH to increased cardiovascular morbidity, concluding that the majority of deaths among
NASH patients are attributable to cardiovascular disease (cardiovascular death is four times higher than death related to liver disease).

In considering therapeutic options to treat NASH, we believe it is important to address the underlying metabolic co-morbidities in addition to the

liver pathology.

Diagnosis

Most people with NASH are asymptomatic and their disease is often discovered incidentally following a liver imaging procedure, such as an

ultrasound, prescribed for other reasons or as part of an investigation for elevated liver enzymes. Once suspected clinically, a liver biopsy is required to
definitively diagnose NASH, which necessitates the joint presence of steatosis, ballooning and lobular inflammation. Once pathologically confirmed, the
severity of NAFLD and NASH is determined using the histologically validated NAS, which grades disease activity on a scale of 0 to 8. The NAS is the
sum of the individual scores for steatosis (0 to 3), lobular inflammation (0 to 3), and hepatocellular ballooning (0 to 2) but does not include a score for
fibrosis.

Fibrosis staging (F0-F4) relies on the Kleiner classification (F0 = no fibrosis; F1 = perisinusoidal or periportal fibrosis (not both); F2 = both

perisinusoidal and periportal fibrosis; F3 = bridging fibrosis; F4 = cirrhosis).

Histological diagnosis remains the gold standard for assessment of NASH and fibrosis. However, given that liver biopsy is associated with risks of
pain, bleeding and other morbidity, as well as significant cost, the procedure is not practical for general patient screening. Several non-invasive tools such
as clinical risk scores and imaging techniques are increasingly used to assess NASH patients. Clinical risk scores such as the NAFLD fibrosis score,
Fibrosis-4 index, the Enhanced Liver Fibrosis score and vibration-controlled transient elastography (“VCTE”), have been validated and are increasingly
used. These tools have an excellent negative predictive value and an acceptable positive predictive value for detection of advanced (≥ F3) fibrosis, and are
increasingly used in clinical settings. Additionally, evidence is emerging that shows a correlation between reduction in steatosis as measured by magnetic
resonance imaging proton density fat fraction (“MRI-PDFF”) and improvement histological changes in the liver. Extensive efforts are also under way to
develop non-invasive means to identify patients with NAS ≥ 4 or fibrosis ≥ F2 patients without a need for a liver biopsy. In a recent draft guidance, the
FDA encouraged sponsors to identify biochemical or noninvasive imaging biomarkers that, once characterized and agreed by the FDA, could replace liver
biopsies for patient selection and efficacy assessment in clinical trials.

We expect that the validation and subsequent adoption of these new tools will result in an increase in the diagnosis and treatment rates for NASH in

the future.

Prevalence

The prevalence of NASH has increased significantly in recent decades, paralleling similar trends in the prevalence of obesity, insulin resistance and

Type 2 diabetes. Alarmingly, the prevalence of these conditions is expected to increase further in view of the unhealthy nutrition habits, such as
consumption of a diet high in fructose, sucrose and saturated fats, and sedentary behavior that characterize modern lifestyle. In the United States, the
number of NASH cases is projected to expand from 16.5 million in 2015 (5.1% of the population) to 27 million in 2030. Approximately 20% of the 16.5
million NASH cases in 2015 had F3/F4 fibrosis, a number that is expected to increase to 7.9 million by 2030, which will be approximately 30% of the total
NASH population. Similar growth trends for NASH cases are expected in Europe (12.6 million in 2016 to 18.3 million in 2030 within France, Germany,
Italy, Spain and the United Kingdom) as well as China (32.6 million in 2016 to 48.3 million in 2030).

10

 
Since no approved drugs exist currently, NASH is emerging as a major economic issue. Lifetime costs of all NASH patients in the United States in
2017 was estimated at $223 billion, and the cost of the advanced NASH population was estimated at $95 billion with estimated increase in NASH cases (as
mentioned above) further expected to drive costs upwards. Progression of patients along the NASH continuum further adds to costs as mean health care
costs (per month) were 32% and 247% higher for patients with compensated cirrhosis ($1,870) and end-stage liver disease ($4,931), respectively, compared
to those without cirrhosis ($1,420) and these results were independent of age. The economic burden of NASH is expected to continue to increase, as NASH
is anticipated to become the leading cause of liver transplants by 2020 in conjunction with the significant increase in liver transplant costs ($577,000 in
2013 to $812,500 in 2017).

Overview of NASH Treatment Options

There are currently no approved therapies for the treatment of NASH. We believe four key attributes are essential for successful NASH therapies:

(1) robust efficacy with respect to liver pathologies; (2) ability to address underlying co-morbidities associated with the disease; (3) limited tolerability
issues at effective doses; and (4) patient convenience. Figure 4 below summarizes the primary interventional and therapeutic approaches to NASH that are
in existence or under development and their key advantages and limitations.

We believe that the market for NASH treatments will evolve to be similar to the multi-billion dollar markets for diabetes and dyslipidemia

treatments and has the potential to support multiple successful commercial products across different therapeutic classes as well as within the same class.
Further, we believe potent injectable therapies have the potential to be a preferred treatment option for some patient populations.

Our Solution

Summary

We are developing BIO89-100, a specifically engineered glycoPEGylated analog of FGF21, for the treatment of NASH and other liver and cardio-
metabolic indications. FGF21 is an endogenous metabolic hormone that is naturally found as a monomeric, non-glycosylated protein and is known to play
a key role in regulating energy expenditure, and glucose and lipid metabolism. FGF21 has been clinically shown to reduce steatosis in the liver. It is also
thought to exert effects on liver fibrosis by improving metabolic regulation, which reduces ongoing liver injury thus giving the liver time to heal. FGF21
also generates an on-target effect to increase adiponectin, a hormone released from adipose tissue that, among other functions, can suppress development
and progression of hepatic fibrosis. Given the relevant and broad-based effects of FGF21, we believe it is a compelling pharmaceutical target for treating
NASH, which may offer benefits and/or address the limitations relative to the therapeutic approaches described in Figure 4 above. We believe FGF21
analogs such as ours have the potential to be the mainstay of therapies for NASH because they can address liver pathologies and the underlying metabolic
dysregulation which result in NASH progression. However, FGF21 in its native form is not suitable as a pharmacological product given it is rapidly broken
down by the body and it is unstable in soluble formulation. BIO89-100 is specifically engineered to overcome these challenges while maintaining the
efficacious properties of the endogenous molecule. We believe BIO89-100 may be a differentiated FGF21 therapy based on its robust and durable
biological effects and a favorable tolerability profile, as well its potential for a longer dosing interval. We are currently evaluating BIO89-100 in a POC
Phase 1b/2a clinical trial in patients with NASH or patients with NAFLD and high risk of NASH.

FGF21 Overview

Fibroblast growth factors (“FGFs”), including FGF21 and FGF19, are a large family of cell-signaling proteins involved in the regulation of many
processes within the body. FGF21 is an endogenous metabolic hormone that regulates energy homeostasis, glucose-lipid-protein metabolism and insulin
sensitivity, and modulates the pathways that mitigate against intracellular stress. FGF21 is secreted primarily by the liver but is also secreted by the white
adipose tissue (“WAT”), skeletal muscle and the pancreas. FGF21 exerts its biological benefits through the activation of three fibroblast growth factor
receptors (“FGFRs”), FGFR1c, FGFR2c and FGFR3c, and requires co-activation of the transmembrane protein cofactor beta Klotho (“ß-Klotho”). FGF21
is not believed to activate FGFR4, which has been associated with adverse effects. FGF21 can act directly or indirectly on target organs by mediating
downstream regulators, such as adiponectin, and upstream regulators that induce FGF21, such as nutritional stress or transcription factors. Figure 5 below
shows effects of FGF21 on the body.

12

 
Figure 5: Biological Effects of FGF21

Reducing Liver Steatosis by Improving Lipid Handling and Insulin Sensitivity

FGF21 has been clinically shown to reduce liver steatosis. FGF21 reduces liver steatosis by (1) increasing fatty acid oxidation in the liver, (2)

reducing the deposition of free fatty acids from peripheral tissue to the liver and (3) reducing DNL in the liver. FGF21 exerts its systemic effects by
reducing the serum levels of lipids (e.g., triglycerides, LDL cholesterol) and increasing insulin sensitivity. Increasing insulin sensitivity reduces lipolysis
and can also reduce serum levels of lipids. In particular, FGF21 has been demonstrated to reduce liver fat in patients with NASH and has also shown
beneficial effects in obese diabetic patients on both serum levels of lipids and insulin resistance.

Improving Liver Inflammation and Fibrosis

FGF21 is believed to reduce liver fibrosis, the pathological change mostly clearly linked to liver-related morbidity in NASH patients via two
potential pathways. One pathway is through the metabolic benefits of FGF21 described above. Long-term improvements in metabolic regulation reduce the
ongoing liver injury that drives fibrosis and thus allows the liver time to heal. The other pathway is a direct anti-fibrotic effect mediated via adiponectin, an
adipokine that is upregulated by FGF21. Increased adiponectin downregulates the hepatic stellate cells that are activated upon hepatic injury and
responsible for collagen deposition and subsequent fibrosis.

13

 
 
 
FGF21 Signaling

As noted above, FGF21 exerts its biological benefits through the co-activation of FGFRs and ß-Klotho. FGFRs are expressed widely throughout
the body whereas ß-Klotho is primarily expressed in metabolic tissues such as adipose tissue, liver, and pancreas, thereby providing organ specificity to
FGF21.

As illustrated in Figure 6 below, the binding of FGF21 is a two-step process. The C-terminus of FGF21 initially binds to ß-Klotho enabling the N-
terminus to form an expanded complex with one of the FGFRs. Once the co-receptor complex has formed with ß-Klotho and one of the FGFRs, a series of
intracellular signaling cascades is initiated. These signaling cascades enable FGF21 to exert its biological functions.

Figure 6: FGF21’s two-step receptor binding with ß-Klotho and FGFRs

FGF21 activates three specific FGFRs (FGFR1c, FGFR2c and FGFR3c), which based on nonclinical studies and clinical trials, appear to be

responsible for mediating the desired therapeutic actions of FGF21 in NASH. FGF19 activates these receptors and acts upon another FGFR known as
FGFR4. Activation of FGFR4 results in an increase in LDL cholesterol and has been implicated in the etiology or progression of HCC. The activation and
downstream signaling pathways of FGF21 are shown in Figure 7 below.

14

 
 
 
Figure 7: FGF21 Receptor Activation

Overcoming the Challenges of Developing FGF21 as a Pharmaceutical Product

While the observed pharmacological effects of recombinant human FGF21 in preclinical disease models clearly highlight its therapeutic potential,

FGF21 in its native form is not suitable for commercialization for two key reasons:

•

•

Native FGF21 is rapidly broken down in the bloodstream and cleared through the kidneys. The native form of FGF21 is a 19.4 kDa
protein with a half-life estimated to be less than two hours. Reducing renal clearance and protecting both ends of the protein from
proteolysis remains key to extending half-life and thereby extending the duration of its effect. If the N-terminus is not intact, signaling
activity of FGF21 is significantly reduced. However, if the C-terminus is not intact, FGF21’s ability to bind with ß-Klotho is impaired,
thereby rendering it inactive.

Native FGF21 is unstable and has a tendency to aggregate in solution. Hence, it is operationally challenging to develop a stable liquid
formulation at high concentration with low viscosity, which is required to achieve good bioavailability via subcutaneous injection.

15

 
 
 
 
 
Clinical Validation of FGF21 and FGF class of drugs

We believe FGF21 has the potential to be the mainstay monotherapy for NASH because it addresses multiple facets of the disease. Specifically, it

has the potential to reduce steatosis, improve fibrosis and importantly, impact the metabolic dysregulation which continues to promote disease progression.
The potential for FGF21 analogs in the treatment for NASH has been demonstrated by clinical trial data with pegbelfermin, a pegylated form of FGF21. In
a third-party Phase 1b study, pegbelfermin was observed to result in reductions in triglycerides, LDL-C and HDL. In addition, a third-party Phase 2a study
conducted in patients with biopsy-proven NASH, pegbelfermin showed a significant reduction in absolute hepatic fat fraction measured by MRI-PDFF, a
significant increase in adiponectin concentration, a decrease in mean liver stiffness and a significant decrease in concentration of PRO-C3, a biomarker of
fibrosis. Clinical outcomes were better when dosed as a daily injection versus a weekly injection. The compound was deemed generally well tolerated,
although a higher frequency of gastrointestinal adverse events was reported in treated patients versus placebo.

A second compound, selectively activating the FGFR1c and its co-receptor ß-Klotho, reported reductions in liver fat content and improvements in

metabolic parameters in a study in NAFLD patients.

In addition, the potential for FGF19 analogs in the treatment for NASH has been demonstrated with aldafermin, an engineered version of the

human hormone FGF19. In a third-party Phase 2 study conducted in patients with biopsy-confirmed NASH, aldafermin showed a significant reduction in
absolute liver fat content measured by MRI-PDFF and a statistically significant improvement in fibrosis and NASH resolution relative to placebo after 24
weeks of treatment. FGF19 and FGF21 share key commonalities in their mechanism of action and activate many of the same FGF receptors in the body.
However, a key difference is that FGF21 is not believed to activate the FGFR4 receptor while FGF19 does activate this receptor. As a result of the
activation of FGFR4, LDL levels rise and aldafermin treatment resulted in significant increase in LDL levels in the clinical trial necessitating protocol-
driven administration of statins. Additionally, aldafermin was dosed as a once daily injection in the trial.

BIO89-100

Overview

We are developing BIO89-100, a specifically engineered glycoPEGylated analog of FGF21, for the treatment of NASH with fibrosis and other

cardio-metabolic indications. BIO89-100 has successfully completed a Phase 1a study, and we are currently evaluating BIO89-100 in a POC Phase 1b/2a
clinical trial in patients with NASH or NAFLD with a high risk of NASH. BIO89-100 has been specifically engineered to: (1) protect against proteolysis
and reduce renal clearance, (2) have an extended half-life, (3) minimize susceptibility to aggregate in solution and (4) optimize its potency, enabling the
potential use of lower dosage/doses. Additionally, we believe that BIO89-100 may enhance binding affinity for ß-Klotho, by altering the conformation of
the C-terminus which could have a positive impact on efficacy.

Primary Structure and Protein Engineering of BIO89-100

BIO89-100 has been optimally constructed with two mutations via substitutions with natural amino acids at site-specific positions (173 and 176)

toward the C-terminus end of the hormone. The mutations were incorporated into the FGF21 sequence after existing proline to create a consensus sequence
for glycosylation. Subsequently, the glycosyl linker and a single 20 kDa glycoPEG moiety were enzymatically introduced at the O-linked glycosylation
consensus site (position 173) via the proprietary glycoPEGylation technology. Our glycoPEG moiety is an activated form of the PEG molecule with the use
of Sialic Acid, CMP-SA-PEG. The proximity of the mutations ensures consistent and efficient attachment of the glycoPEG moiety.

BIO89-100 has two modified natural amino acid residues:

•

•

S173T: Serine modified to Threonine at position 173; and

R176A: Arginine modified to Alanine at position 176.

16

 
 
 
In addition, a Methionine residue was introduced at the N-terminus which acts as the translation initiation signal. A single 20 kDa linear glycoPEG

moiety is attached to the Threonine in position 173 via the proprietary glycoPEGylation technology. Figure 8 below shows the structure of BIO89-100.

Figure 8: Structure of BIO89-100

The increase in the size of the molecule from 19.4 kDa to 40 kDa together with the site-specific mutations adjacent to the primary cleavage site of

FGF21 (by the FAP enzyme between positions 171 and 172 on the native amino acid chain, which would be represented by positions 172 and 173 in our
molecule starting with Methionine in position 1) are designed to prolong the half-life of the molecule. Additionally, we believe that the use of
glycoPEGylation technology produces a comparatively stronger and more flexible structure, which aids in the development of a stable formulation.
PEGylation technology has been used successfully in many pharmaceutical products including products that have been marketed for more than 10 years.

BIO89-100 uses a proprietary glycoPEGylation technology that has been previously validated by a third party, as this technology is incorporated in

another pharmaceutical product (Lonquex® by Teva) that has received regulatory approval and is currently commercialized in the European Union.

The Development and Selection of BIO89-100

The discovery program that led to the selection of BIO89-100 was directed towards achieving an optimal PK and efficacy profile. It has been
shown that the in vivo half-life of FGF21 can be extended by covalently linking a single glycoPEG moiety to the molecule. We performed extensive
screening of FGF21 analogs with mutations at different positions including close to the N-terminus, as well as different glycoPEGylations to select an
optimized molecule based on its potency, PK and in-vivo efficacy.

Stage I—Optimizing Selection of Mutation Sites—In Vitro Potency Testing

Mutations were inserted at different sites for both non-PEGylated FGF21 analogs and corresponding glycoPEGylated analogs and screened in a
cell-based potency assay to select analogs that did not lose potency relative to the native hormone. Amongst the multiple glycoPEGylated analogs tested,
only mutations at sites towards either N-terminus or C-terminus showed potency comparable to that of native FGF21 hormone and were selected for further
development.

17

 
 
 
Stage II—Optimizing for glycoPEG (20 kDa vs 30 kDa)—In Vitro Potency Testing

Analogs selected in Stage I were prepared with either a 20 kDa or a 30 kDa glycoPEG moiety and tested for potency in mouse adipocytes (3T3-L1)

and human embryonic kidney (HEK-293) cell lines. Minimal differences in potencies were observed between the 20 kDa and 30 kDa glycoPEGylated
analogs. However, only the glycoPEGylated analogs that had mutations and a glycoPEG attachment at the C-terminus, as distinct from those with
mutations at the N-terminus, maintained their potency in both mouse and human cell lines. These analogs were selected for future development.

Stage III—Optimizing for PK Properties and Efficacy—In Vivo Testing

Selected analogs from Stage II with either a 20 kDa or a 30 kDa glycoPEG moiety, were chosen for in vivo testing in a diabetic mouse model. In

addition to PK, changes from baseline in glucose, triglycerides and insulin were measured. The data showed that the circulating half-life of the
glycoPEGylated analogs for both glycoPEG sizes was extended (range 15 to 30 hours) as compared to native FGF21 (2 hours). As expected, all analogs
were observed to cause a reduction in blood glucose levels. However, the 20 kDa glycoPEGylated analogs were observed to outperform the 30 kDa analogs
by improving triglycerides at lower doses and across broader dose ranges. BIO89-100 resulted in the greatest reduction of insulin and was selected as the
candidate for clinical development.

In summary, the mutations made to the native FGF21 molecule and the addition of the 20 kDA glycoPEG moiety via the use of the

glycoPEGylation technology were observed to significantly improve the PK properties of the molecule while retaining the therapeutic benefits. We believe
that BIO89-100 is a well-balanced molecule with a unique profile, which has the potential to have therapeutic benefits in NASH and cardio-metabolic
diseases. Figure 9 below sets forth what we believe are the key features and potential benefits of BIO89-100:

Therapeutic Potential of BIO89-100 Supported by Preclinical Animal Models of NASH, Diabetes and Obesity

BIO89-100 was evaluated in multiple distinct animal models of NASH, diabetes and obesity, including non-human primate studies. In each of

these studies, consistent and significant beneficial effects were observed across a range of endpoints, specifically, robust improvements in lipid handling,
glycemic control and insulin resistance as well as significant improvements in hepatic steatosis, injury and fibrosis. We believe these results demonstrate
the potential of BIO89-100 to simultaneously address the multiple drivers of NASH pathogenesis. The histological endpoints, NAS and fibrosis score,
mirror the endpoints we expect to assess in our clinical development. In addition, treatment with BIO89-100 in animal models was observed to result in
consistent reductions in body weight.

BIO89-100 has been evaluated in three animal models of direct relevance to NASH. These included: (1) Stelic Animal Model (“STAM”), (2) Diet-
induced NASH (“DIN”) model and (3) spontaneous diabetic obese cynomolgus monkey model. Additional studies done in diabetes mouse model and diet
induced obesity mouse model showed benefits in key markers of relevance in NASH.

A wide range of doses were tested in these studies as well as weekly and once every two week dosing regimen was tested in a cynomolgus monkey

study. The key outcomes of these studies are summarized in Figure 10 below.

Results of DIN Mouse Studies

Two pharmacology studies were conducted in a DIN mouse model. In the first study of 40 mice (10 per treatment group), the animals received
BIO89-100 via a subcutaneous injection at 0.5 and 2 mg/kg every 3 days for 10 weeks, and a detailed assessment of liver parameters was performed to
evaluate the effectiveness of the dosing regimen. Both doses of BIO89-100 were observed to reduce the total NAS significantly based on histological
evaluation and improved measures with respect to both lipid handling and insulin sensitivity. In addition, expression of hepatic genes involved in
inflammation and fibrosis were significantly reduced following administration of BIO89-100. In the second DIN mouse study of 50 mice (10 per treatment
group), lower dose levels of BIO89-100 were tested (0.02, 0.1 and 0.5 mg/kg every 3 days) but the treatment duration was longer at 19 weeks. In this study
too, BIO89-100 was observed to result in significant reductions in the liver damage induced by the diet in a dose-dependent manner. Specifically, treatment
with BIO89-100 was observed to result in a significant mean reduction of the histological markers of NASH (Figure 11), as well as a reduction in the
marker of hepatic injury (alanine amino transaminase (“ALT”)) (Figure 12), in liver lipids (Figure 13), and in inflammatory and fibrotic markers (Figure
14), each in a dose dependent manner compared to vehicle treatment. In addition to the beneficial effects on the liver, treatment with BIO89-100
demonstrated significant improvements in glycemic control and weight loss. As NAS and measures of fibrosis are histological endpoints for the assessment
of NASH in clinical studies, we believe that the observations in the STAM and DIN mouse models suggest that BIO89-100 is a compelling candidate for
the treatment of NASH.

Results of Spontaneously Diabetic Obese Cynomolgus Monkey Studies

BIO89-100 efficacy was evaluated in 24 spontaneously diabetic obese cynomolgus monkeys (six per treatment group) after multiple subcutaneous

doses. In the first study, BIO89-100 was administered at doses of 0.1, 0.3 and 1 mg/kg once per week for 8 weeks followed by a 6-week washout phase.
Administration of BIO89-100 showed significant effects on triglycerides at all doses tested, with a highly robust 78% reduction observed at the highest
dose level of 1 mg/kg/week (Figure 15). Statistically significant mean reductions were observed in total cholesterol (Figure 16), glucose (Figure 17),
insulin, glycated hemoglobin (HbA1c) and ALT (Figure 18), along with improvement in oral glucose test results.

In a second multiple-dose study in 24 spontaneously diabetic obese cynomolgus monkeys (six per treatment group), BIO89-100 was administered

for 4 weeks at 1 mg/kg once weekly or 1 or 2 mg/kg given once every 2 weeks. A rapid and dramatic reduction in triglycerides (Figure 21), up to 76%, was
observed with BIO89-100. Statistically significant mean reductions were also observed in body weight (Figure 19), HbA1c (Figure 20), glucose, and
insulin, along with increased adiponectin levels (Figure 22) and improvement in oral glucose test results in all BIO89-100-treated groups (both once
weekly and every 2 weeks) in comparison to the vehicle group. The robust effect on body weight and HbA1c over the 4-week treatment period were
particularly unexpected. The PD effects were relatively similar across all three dosing groups suggesting that once every two weeks could be a viable
clinical dosing strategy. BIO89-100 was also assessed in a study of sweetness preference in six obese cynomolgus monkeys. Using a two-bottle sweetness
preference test, monkeys given BIO89-100 at 1 mg/kg by subcutaneous injection every week for three weeks demonstrated a substantial reduction in
sweetness preference and improvements in certain lipid parameters compared to monkeys given vehicle treatment.

Figure 22: Changes in Adiponectin with BIO89-100 in Diabetic Monkey Study 2

We believe the PD effects observed in the animal studies suggest that BIO89-100 is a potent molecule that may address the key pathways in NASH

by (1) improving lipid handling and resultant steatosis, (2) improving insulin resistance, (3) reducing hepatocyte injury and inflammation and (4)
improving fibrosis. Additionally, the data from the cynomolgus monkey studies suggest that the molecule may be amenable to an extended dosing interval.

BIO89-100 Clinical Development

We are developing BIO89-100 for the indication of NASH with fibrosis. In our randomized, double-blind, placebo-controlled, Phase 1a, first-in-

human, SAD clinical trial of BIO89-100 of 58 healthy volunteers, 43 healthy volunteers received BIO89-100 with a half-life of 55 to 100 hours and 15
received placebo treatment. In this SAD study, BIO89-100 was well tolerated, with all treatment related adverse events reported as mild; there were no
serious adverse events reported. At single doses of 9.1 mg and higher, we observed significant improvements in key lipid parameters measured at Day 8
and Day 15 after dosing on Day 1. The mean changes versus baseline include reductions in triglycerides (up to 51%) and LDL-C (up to 37%) and increase
in HDL-C (up to 36%) despite the baseline values being in the normal range. As compared to placebo treatment, these mean changes were all statistically
significant (p < 0.001). BIO89-100 demonstrated rapid (starting from Day 2), sustained and durable improvements on lipid parameters for two weeks or
more after single dose administration. We believe this duration of effect further supports the possibility of an extended dosing interval, as observed in our
preclinical studies.

Phase 1a Clinical Trial of Single Dose of BIO89-100 in Healthy Volunteers

We conducted a Phase 1a clinical trial to evaluate the safety, tolerability and PK of BIO89-100 in healthy volunteers. We enrolled a total of 58
healthy volunteers into one of seven cohorts and randomized to receive a single dose of BIO89-100 or a placebo. Forty-three healthy subjects received
BIO89-100 at the following doses: 0.45 mg, 1.2 mg, 3 mg, 9.1 mg, 18.2 mg, 39 mg and 78 mg.

26

 
 
 
BIO89-100 Exhibited Generally Linear, Dose-proportional PK

The PK profile of BIO89-100 was generally dose-proportional or slightly more than dose-proportional with T1/2 range from approximately 55 to

100 hours. As shown in Figure 23 below, the observed median time of maximum serum concentration ranged from 36 to 60 hours.

Figure 23: Single-dose PK of BIO89-100

27

 
 
 
Our Phase 1a clinical trial enrolled healthy volunteers with a mean (SD) age and BMI of 39.3 (9.7) years and 26.7 (3.1) kg/m2 respectively, with

laboratory parameters in the normal range at baseline (mean values: TG 94.0 mg/dL; LDL 124.1 mg/dL; HDL 47.7 mg/dL). Even in this healthy study
population, after a single dose administration of BIO89-100 at doses 9.1 mg and higher, robust and durable PD effects were observed across key lipid
parameters, including triglycerides (Figures 24 and 25), LDL (Figure 26) and HDL (Figure 27), over two weeks. The changes in lipids parameters started
from Day 2 with maximal effects typically observed at Day 8 or Day 15. The effect on lipid parameters was generally dose-dependent, with single doses of
BIO89-100 at 9.1 mg and higher, demonstrating significant improvements versus baseline in key lipid parameters measured at Day 8 and Day 15 following
dosing. The BIO89-100 effects appeared to plateau at 39 mg with minimal additional effect observed in 78 mg. BIO89-100 also led to increases in mean
adiponectin levels (up to 146% relative to baseline) when measured at Day 8 and Day 29.

BIO89-100 was well tolerated across the dose range in our Phase 1a clinical trial. There were no deaths, serious adverse events or discontinuations

due to adverse events. The most commonly observed treatment-related adverse events, occurring in at least two subjects in the pooled BIO89-100 group,
were injection site reactions and headache, all of which were reported as mild. Injection site reactions were more frequent in the 39 mg cohort, likely due to
a larger injection volume administered at one time in that cohort. No clinically meaningful trends were observed in gastrointestinal events, laboratories or
vital signs including blood pressure or heart rate changes. No tremors were reported. Five of 43 BIO89-100 treated subjects tested positive for anti-drug
antibodies (“ADA”); however, all titers were low (≤ 16) and did not appear to affect the PK or safety profile.

Treatment-related treatment emergent adverse events (“TEAE”) reported in two subjects or more in pooled BIO89-100 treatment group are shown

in Figure 28 below.

These data supported the advancement of BIO89-100 into a study in patients with NASH or patients with NAFLD and a high risk of NASH to

evaluate BIO89-100’s potential as a treatment of NASH. Based on PK/ PD modeling and drug exposure analysis, we have identified BIO89-100 doses in
the range of 9 mg to 36 mg weekly (“QW”) or every other week (“Q2W”) as the target dose range for evaluation in future clinical trials in patients with
NASH or patients with NAFLD and a high risk of NASH.

We believe that the totality of the data from our Phase 1a study, the preclinical data with BIO89-100 and the clinical data from third parties
collectively support the hypothesis that BIO89-100 has the potential to address the complex nature of NASH, especially given the frequency of metabolic
co-morbidities in NASH patients. The magnitude and significance of BIO89-100’s biological effects after a single dose on lipid parameters in healthy
volunteers were observed to be robust and durable, and the magnitude of these reductions appear to be comparable or better than data reported to date in
Phase 1 clinical trials of other FGF analogs, although no head-to-head studies have been conducted.

Phase 1b/2a POC Clinical Trial

In the second quarter of 2020, we expect to complete patient enrollment in our Phase 1b/2a POC clinical trial. Our clinical trial is a multicenter,
randomized, double-blind, placebo-controlled, multiple ascending dose-ranging trial in patients with NASH or patients with NAFLD and a high risk of
NASH, with 83 total patients randomized to receive QW or Q2W subcutaneous dosing of BIO89-100 or placebo for up to 12 weeks. This clinical trial is
designed to assess the safety, tolerability and PK properties of BIO89-100 as well as change in liver fat measured by MRI-PDFF and key biomarker
assessments. These data are aimed at providing proof-of-concept for BIO89-100 in NASH and help inform dose selection for larger, longer-term paired-
biopsy trials. At our meeting with the FDA in June 2019, the FDA concurred with our overall trial design, including study population, dose selection and
study treatment duration.

Our POC study is enrolling patients with NASH or patients with NAFLD and a high risk of NASH, defined as patients with steatosis greater than

10% who have central obesity and Type 2 diabetes or central obesity and evidence of liver injury. NAFLD patients, especially the subset of NAFLD
patients we will enroll, have similar disease characteristics as patients with biopsy-proven NASH, and we expect that the data from these NAFLD patients
will be informative regarding the potential of BIO89-100 as treatment for NASH. The trial will include a set number of patients with biopsy confirmed
NASH with fibrosis (F1-F3) to help inform the design of subsequent clinical trials.

The key objectives of the trial are to:

•

•

•

•

•

evaluate the safety and tolerability of multiple ascending doses of BIO89-100;

assess change from baseline in liver fat (measured via MRI-PDFF);

assess changes from baseline in lipids, glycemic control parameters, fibrosis and inflammation markers;

characterize the PK properties of BIO89-100; and

evaluate the immunogenicity of BIO89-100 as measured by presence of ADA.

31

 
 
 
 
 
 
The design of the trial is presented in Figure 29 below:

Figure 29: POC Clinical Trial Design

Our planned active treatment groups are: 3 mg, 9 mg 18 mg and 27 mg QW, and 18 mg and 36 mg Q2W. In February 2020 we completed the

second dose escalation and began enrolling patients in the final three dose cohorts. We have designed the trial to detect differences on MRI-PDFF between
BIO89-100 at different dose levels and the pooled placebo group. We expect to report topline data in the second half of 2020. In addition, we anticipate
initiating a Phase 2b trial in the first half of 2021.

BIO89-100 Differentiation

We believe BIO89-100 could have a differentiated profile relative to other therapies targeting FGF21 and FGFR1c that are in development.

A PEGylated form of FGF21 is currently in two third-party Phase 2b studies in NASH. The compound has a reported half-life of 19 to 24 hours

and includes mutations with non-native amino acid substitutions. In this third party’s Phase 2a study, the molecule showed a significant reduction in
absolute liver fat measured by MRI-PDFF and a significant decrease in concentration of PRO-C3 (a biomarker of fibrosis), but no significant changes on
lipid markers. Study outcomes were better when dosed as a daily injection versus a weekly injection. The compound was deemed generally well tolerated,
although a higher frequency of gastrointestinal adverse events was reported in treated patients. Sixty-three percent to 92% of treated patients in the Phase
2a study tested positive for anti-drug and anti-FGF21 antibodies.

32

 
 
 
A second compound, a long-acting Fc-FGF21 fusion protein with extended half-life of approximately three to four days, has completed third-party

Phase 1 studies in which patients with Type 2 diabetes demonstrated decreases in triglycerides and increases in HDL-C, with improvements in insulin
sensitivity, but modest to no changes in LDL in doses approximating those advancing to further development. The highest doses tested in the single and
multiple-ascending dose study were not well-tolerated with adverse events of significance being gastrointestinal disorders and tremors. The compound is
currently in a Phase 2a study in NASH with weekly dosing.

A third compound, an agonistic antibody selectively activating FGFR1c and its co-receptor ß-Klotho, has completed a third-party Phase 1 study as

a once-monthly injectable insulin sensitizer for the treatment of NASH. Reductions in liver fat content and improvements in metabolic parameters were
reported in a clinical trial evaluating a high single dose in obese, insulin-resistant, non-diabetic subjects with NAFLD. The most common adverse events
reported were injection site reaction and increased appetite. Subjects gained an average of 1.6 kg body weight 36 days after dosing compared to baseline.
The compound agonizes only the FGFR1c receptor and is not believed to have any activity on the FGFR2c and FGFR3c receptors.

We believe BIO89-100 may be a differentiated FGF21 therapy based on its robust and durable biological effects and a favorable tolerability profile.
In addition, BIO89-100 has the potential for a once every two-weeks dosing interval that could provide significant value to asymptomatic patients who will
be taking the product chronically. In market research that we conducted amongst obese diabetic subjects (n=150), respondents were asked for their
preference when selecting an injectable product with different dosing regimens for the treatment of a chronic liver condition. In this study, 63% of
respondents expressed a preference or strong preference for a product injected once every two weeks versus a product injected every week, and 68% of
respondents expressed similar preferences for a product injected once every two weeks versus a product injected daily. Further, we believe that BIO89-100
may have a differentiated tolerability profile and that tolerability issues may influence physician and patient preference in NASH, a chronic and generally
asymptomatic disease. We believe the risk of CNS effects, significant gastrointestinal tolerability issues and weight gain could significantly impact
adoption by physicians and patients. Finally, based on the non-human primate study results and the human SAD study results across different lipid markers
(triglyceride reduction up to 51% and LDL reduction up to 37%), we believe BIO89-100 may offer robust and durable biological effects. We believe that
activation of the FGFR1c, 2c and 3c receptors may confer benefits versus activation of a single receptor (FGFR1c) given the expression of the receptors in
the key organs of interest (FGFR1c in adipose tissue and FGFR2c and FGFR3c in the liver) and provide a more balanced approach.

Severe Hypertriglyceridemia

We also intend to develop BIO89-100 for the treatment of SHTG. Hypertriglyceridemia (“HTG”) is characterized by elevated fasting plasma

triglyceride levels higher than 200 mg/dL and SHTG is typically defined as triglyceride levels of greater than or equal to 500 mg/dL. SHTG is associated
with an increased risk of NAFLD, NASH and cardiovascular diseases, as well as acute pancreatitis, accounting for up to 10% of all acute pancreatitis
episodes. A recent third-party study utilizing an omega-3 fatty acid (“omega-3 FA”) demonstrated the linkage between a reduction in triglycerides and
favorable cardiovascular clinical outcomes.

It is estimated that there are 2.5 million to 4 million patients in the United States with triglyceride levels of greater than or equal to 500 mg/dL. Of
these patients, it is estimated that 42% have dyslipidemia and 27% have diabetes. This patient population is expected to increase due to the triple epidemic
of obesity, metabolic syndrome and Type 2 diabetes. In addition, the addressable market has the potential to expand as a result of increasing awareness of
the importance of treating elevated TG levels, similar to the focus today of physicians on managing LDL levels, as well as due to third party commercial
efforts expected to promote TG reduction.

The treatment regimen for SHTG includes dietary restrictions and lipid-lowering drug treatment such as fibrates, omega-3 fish oils and niacin.

Some statins are indicated in HTG but do not have an indication for use in SHTG. In third-party studies, up to 50% of treated SHTG patients were unable
to reduce their triglyceride levels to < 500 mg/dL despite using approved drugs and are considered refractory patients. These refractory patients have
substantial unmet medical need and represent a significant market opportunity as there are no approved therapies for the treatment of refractory SHTG.

33

 
Despite multiple agents approved for the treatment of SHTG, these agents have limitations that may not make them ideal for all patients. For

example, fibrates have demonstrated reductions in triglycerides of up to approximately 55% at 12 weeks of treatment. However, they have also shown
increases in LDL-C (up to 45%), a detrimental effect in this patient population, risk of drug-drug interactions and increases in transaminases, as well as
tolerability issues including myopathy. Omega 3 fish oils have shown more modest benefits in reduction of triglycerides from baseline of approximately
25% to 45%. However, fish oils with a higher percentage reduction in triglycerides have also showed major increases in LDL-C (up to 45%). Fish oils also
have a significant pill burden given the high daily doses required. In addition, these agents fail to meaningfully address the related co-morbidities of SHTG,
including glycemic control, which, when left untreated, may further exacerbate the condition. Yet, despite these limitations, the existing drugs have
achieved commercial success with two third parties each generating peak sales of approximately $1 billion or greater. While we believe BIO89-100 has the
potential to address the co-morbidities of SHTG, there is no guarantee that it would earn comparable peak sales if it is approved by the FDA. Given the
continuing unmet need in SHTG and limitations of current treatments, there are several agents in development for the treatment of SHTG, including a fish
oil product, a fibrate, and novel drugs primarily targeting rare, genetically defined subsets of SHTG, including ANGPTL3 and ApoC III inhibitors.
Dyslipidemia apart from SHTG also continues to be a very active area for pharmaceutical development. We believe BIO89-100 may be a differentiated
SHTG therapy due to its pleiotropic metabolic benefits and its potential to target a broader patient population versus those therapies primarily targeting
rare, genetically defined subsets of SHTG.

BIO89-100 has demonstrated significant reduction in triglyceride levels in both its non-human primate studies and our Phase 1a clinical study. In
diabetic obese cynomolgus monkeys with elevated triglyceride levels, BIO89-100 showed significant effects on triglycerides with a maximal reduction of
78% and 76% at doses of 1 mg/kg (see Figures 15 and 21). In monkeys treated with baseline levels of triglycerides > 500mg/dL (n=4), the three monkeys
treated with BIO89-100 1 mg/kg weekly had TG reductions > 90% at study end. In our Phase 1a clinical study, in patients with baseline triglyceride values
in the normal range (mean baseline 94 mg/dL), BIO89-100 demonstrated reductions of triglycerides from baseline up to 51% at Day 8 after a single dose in
healthy volunteers. While currently approved SHTG therapies decrease TG levels, they generally do not have broader metabolic benefits. In our Phase 1a
study, BIO89-100 demonstrated a reduction in LDL of up to 37% (see Figure 26) and to the extent that we are able to show in subsequent human clinical
trials that BIO89-100 significantly decreases both TG and LDL-C levels and improves other metabolic parameters, such as glycemic control, we believe
that BIO89-100 could be a differentiated therapy in this indication. Based on a mechanism of action that is distinct from the currently approved therapies,
we believe that BIO89-100 has the potential to be used as a monotherapy agent or in combination with other agents. Another FGF21 analog developed by a
third party has also demonstrated a statistically significant reduction in triglycerides in obese, Type 2 diabetes patients. We intend to initiate a Phase 2 trial
in SHTG patients in the first half of 2020 in order to evaluate the ability of BIO89-100 to reduce triglyceride levels compared to baseline levels and to
report topline data in the first half of 2021. Secondary endpoints will evaluate other lipids, high sensitivity C-reactive Protein (hsCRP), glucose, body
weight, safety, and pharmacokinetics. We expect this Phase 2 trial to enroll approximately 90 patients with triglyceride levels greater than or equal to 500
mg/dL at baseline and include both patients on no background triglyceride lowering therapy or on a stable dose of statin and/or prescription fish oil.
Patients will be randomized to receive multiple doses of BIO89-100 or placebo for six to eight weeks.

There is regulatory precedence in the United States for the approval of therapies to treat SHTG based on such therapies demonstrating a reduction

in triglycerides from baseline at 12 weeks. The FDA surrogate endpoint table for drug approval lists a reduction in triglycerides from baseline as the
endpoint for full approval of a therapy in SHTG. A clinical outcome study was not required for certain third-party approvals in SHTG or as a post-
marketing commitment. The SHTG Phase 3 trial for some of these products consisted of a single study of a 12-week duration with 75 to 100 patients per
treatment group. Based on current plans, we anticipate initiating a registrational trial in SHTG patients by the end of 2021, which we expect will follow
existing SHTG regulatory precedence.

Based on FDA guidance for the development of SHTG treatments, as well as the regulatory path followed by other companies that have
successfully developed SHTG therapies, we believe that a combination of smaller clinical trials and shorter development timelines could mean that SHTG
potentially represents a quicker path to market for BIO89-100.

Agreements with Teva

Agreements Relating to FGF21 Program

On April 16, 2018, we entered into an Asset Transfer and License Agreement (the “FGF21 Agreement”) with Teva Pharmaceutical Industries Ltd

(“Teva”), under which we acquired certain patents, intellectual property and other assets relating to Teva’s glycoPEGylated FGF21 program. Under this
agreement, Teva also granted a perpetual, non-exclusive (but exclusive as to BIO89-100), non-transferable, worldwide license to patents and know-how
related to glycoPEGylation technology for use in the research, development, manufacture and commercialization of the compound BIO89-100 and products
containing BIO89-100. In addition, we entered into a Sublicense Agreement with ratiopharm (the “ratiopharm Sublicense”), under which we were granted
a perpetual, exclusive, worldwide sublicense to patents and know-how related to glycoPEGylation technology used in the development, manufacture and
commercialization of BIO89-100 and products containing BIO89-100.

Government Regulation and Product Approval

The FDA and other regulatory authorities at federal, state and local levels, as well as in foreign countries, extensively regulate, among other things,

the research, development, testing, manufacture, quality control, import, export, safety, effectiveness, labeling, packaging, storage, distribution, record
keeping, approval, advertising, promotion, marketing, post-approval monitoring and post-approval reporting of biologics, such as those we are developing.
We, along with third-party contractors, will be required to navigate the various preclinical, clinical and commercial approval requirements of the governing
regulatory agencies of the countries in which we wish to conduct studies or seek approval or licensure of our product candidates.

The process required by the FDA before biologic product candidates may be marketed in the United States generally involves the following:

•

•

•

•

•

•

•

•

•

completion of preclinical laboratory tests and animal studies performed in accordance with the FDA’s current Good Laboratory Practice
regulation;

submission to the FDA of an investigational new drug (“IND”) application, which must become effective before clinical trials may begin
and must be updated annually or when significant changes are made;

approval by an independent Institutional Review Board (“IRB”) or ethics committee at each clinical site before the trial is commenced;

performance of adequate and well-controlled human clinical trials to establish the safety, purity and potency of the proposed biologic
product candidate for its intended purpose;

preparation of and submission to the FDA of a biologics license application (“BLA”) after completion of all pivotal clinical trials;

satisfactory completion of an FDA Advisory Committee review, if applicable;

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

satisfactory completion of an FDA pre-approval inspection of the manufacturing facility or facilities at which the proposed product is
produced to assess compliance with cGMP and to assure that the facilities, methods and controls are adequate to preserve the biological
product’s continued safety, purity and potency, and of selected clinical investigation sites to assess compliance with current Good Clinical
Practices (“cGCP”); and

FDA review and approval of the BLA to permit commercial marketing of the product for particular indications for use in the United States.

Preclinical and Clinical Development

Prior to beginning the first clinical trial with a product candidate, we must submit an IND to the FDA. An IND is a request for authorization from
the FDA to administer an investigational new drug product to humans. The central focus of an IND submission is the general investigational plan and the
protocol(s) for clinical studies. The IND also includes results of animal and in vitro studies assessing the toxicology, PK, pharmacology and PD
characteristics of the product; chemistry, manufacturing and controls information; and any available human data or literature to support the use of the
investigational product. An IND must become effective before human clinical trials may begin. The IND automatically becomes effective 30 days after
receipt by the FDA, unless the FDA, within the 30-day time period, raises safety concerns or questions about the proposed clinical trial. 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 the clinical trial can
begin. Submission of an IND therefore may or may not result in FDA authorization to begin a clinical trial.

Clinical trials involve the administration of the investigational product to human subjects under the supervision of qualified investigators in
accordance with cGCPs, which include the requirement that all research subjects provide their informed consent for their participation in any clinical study.
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 effectiveness criteria to be evaluated. A separate submission to the existing IND must be made for each successive clinical trial conducted during
product development and for any subsequent protocol amendments. Furthermore, an independent IRB for each site proposing to conduct the clinical trial
must review and approve the plan for any clinical trial and its informed consent form before the clinical trial begins at that site, and must monitor the study
until completed. Regulatory authorities, the IRB or the sponsor may suspend a clinical trial at any time on various grounds, including a finding that the
subjects are being exposed to an unacceptable health risk or that the trial is unlikely to meet its stated objectives. Some studies also include oversight by an
independent group of qualified experts organized by the clinical study sponsor, known as a data safety monitoring board, which provides authorization for
whether or not a study may move forward at designated check points based on access to certain data from the study and may halt the clinical trial if it
determines that there is an unacceptable safety risk for subjects or other grounds, such as no demonstration of efficacy. There are also requirements
governing the reporting of ongoing clinical studies and clinical study results to public registries.

For purposes of BLA approval, human clinical trials are typically conducted in three sequential phases that may overlap.

•

•

•

Phase 1—The investigational product is initially introduced into healthy human subjects or patients with the target disease or condition.
These studies are designed to test the safety, dosage tolerance, absorption, metabolism and distribution of the investigational product in
humans, the side effects associated with increasing doses, and, if possible, to gain early evidence on effectiveness.

Phase 2—The investigational product is administered to a limited patient population with a specified disease or condition to evaluate the
preliminary efficacy, optimal dosages and dosing schedule and to identify possible adverse side effects and safety risks. Multiple Phase 2
clinical trials may be conducted to obtain information prior to beginning larger and more expensive Phase 3 clinical trials.

Phase 3—The investigational product is administered to an expanded patient population to further evaluate dosage, to provide statistically
significant evidence of clinical efficacy and to further test for safety, generally at multiple geographically dispersed clinical trial sites.
These clinical trials are intended to establish the overall risk/benefit ratio of the investigational product and to provide an adequate basis for
product approval.

In some cases, the FDA may require, or companies may voluntarily pursue, additional clinical trials after a product is approved to gain more
information about the product. These so called Phase 4 studies may be made a condition to approval of the BLA. Concurrent with clinical trials, companies
may complete additional animal studies and develop additional information about the biological characteristics of the product candidate, and must finalize a
process for manufacturing the product in commercial quantities in accordance with cGMP requirements. The manufacturing process must be capable of
consistently producing quality batches of the product candidate and, among other things, must develop methods for testing the identity, strength, quality
and purity of the final product, or for biologics, the safety, purity and potency. Additionally, appropriate packaging must be selected and tested and stability
studies must be conducted to demonstrate that the product candidate does not undergo unacceptable deterioration over its shelf life.

37

 
 
 
 
BLA Submission and Review

Assuming successful completion of all required testing in accordance with all applicable regulatory requirements, the results of product
development, nonclinical studies and clinical trials are submitted to the FDA as part of a BLA requesting approval to market the product for one or more
indications. The BLA must include all relevant data available from pertinent preclinical and clinical studies, 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. The submission of a BLA requires payment of a substantial application user fee to FDA, unless a waiver or exemption applies.

Once a BLA has been submitted, the FDA’s goal is to review standard applications within ten months after it accepts the application for filing, or, if

the application qualifies for priority review, six months after the FDA accepts the application for filing. In both standard and priority reviews, the review
process is often significantly extended by FDA requests for additional information or clarification. The FDA reviews a BLA to determine, among other
things, whether a product is safe, pure and potent and the facility in which it is manufactured, processed, packed, or held meets standards designed to assure
the product’s continued safety, purity and potency. The FDA may convene an advisory committee to provide clinical insight on application review
questions. Before approving a BLA, the FDA will typically inspect the facility or facilities where the product is manufactured. The FDA will not approve
an application unless it determines that the manufacturing processes and facilities are in compliance with cGMP requirements and adequate to assure
consistent production of the product within required specifications. Additionally, before approving a BLA, the FDA will typically inspect one or more
clinical sites to assure compliance with cGCP. If the FDA determines that the application, manufacturing process or manufacturing facilities are not
acceptable, it will outline the deficiencies in the submission and often will request additional testing or information. Notwithstanding the submission of any
requested additional information, the FDA ultimately may decide that the application does not satisfy the regulatory criteria for approval.

After the FDA evaluates a BLA and conducts inspections of manufacturing facilities where the investigational product and/or its drug substance

will be produced, the FDA may issue an approval letter or a Complete Response letter. An approval letter authorizes commercial marketing of the product
with specific prescribing information for specific indications. A Complete Response letter will describe all of the deficiencies that the FDA has identified in
the BLA, except that where the FDA determines that the data supporting the application are inadequate to support approval, the FDA may issue the
Complete Response letter without first conducting required inspections, testing submitted product lots, and/or reviewing proposed labeling. In issuing the
Complete Response letter, the FDA may recommend actions that the applicant might take to place the BLA in condition for approval, including requests for
additional information or clarification. The FDA may delay or refuse approval of a BLA if applicable regulatory criteria are not satisfied, require additional
testing or information and/or require post-marketing testing and surveillance to monitor safety or efficacy of a product.

If regulatory approval of a product is granted, such approval will be granted for particular indications and may entail limitations on the indicated

uses for which such product may be marketed. For example, the FDA may approve the BLA with a Risk Evaluation and Mitigation Strategy (“REMS”) to
ensure the benefits of the product outweigh its risks. A REMS is a safety strategy to manage a known or potential serious risk associated with a product and
to enable patients to have continued access to such medicines by managing their safe use, and 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 or the development of adequate controls and specifications. Once approved, the
FDA may withdraw the product approval if compliance with pre- and post-marketing requirements is not maintained or if problems occur after the product
reaches the marketplace. The FDA may require one or more Phase 4 postmarket studies and surveillance to further assess and monitor the product’s safety
and effectiveness after commercialization, and may limit further marketing of the product based on the results of these post-marketing studies.

38

 
Expedited Programs for Serious Conditions

The FDA maintains several programs intended to facilitate and expedite development and review of new drugs and biologics to address unmet

medical needs in the treatment of serious or life-threatening diseases or conditions. These programs include Fast Track designation, Breakthrough Therapy
designation, Priority Review and Accelerated Approval. These programs can significantly reduce the time it takes for the FDA to review a BLA, but they
do not guarantee that a product will receive FDA approval. Even if a product qualifies initially, the FDA may later decide that the product no longer meets
the conditions for qualification or decide that the time period for FDA review will not be shortened. In May 2018, the Right to Try Act also established a
program to increase access to unapproved, investigational treatments for patients diagnosed with life-threatening diseases or conditions who have
exhausted approved treatment options and who are unable to participate in a clinical trial.

A new drug or biologic is eligible for Fast Track designation if it is intended to treat a serious or life- threatening disease or condition and

demonstrates the potential to address unmet medical needs for such disease or condition. Fast Track designation provides increased opportunities for
sponsor interactions with the FDA during preclinical and clinical development, in addition to the potential for rolling review once a marketing application
is filed, meaning that the agency may review portions of the marketing application before the sponsor submits the complete application, as well as Priority
Review, discussed below. In addition, a new drug or biologic may be eligible for Breakthrough Therapy designation if it is intended to treat a serious or
life-threatening disease or condition and preliminary clinical evidence indicates that the drug may demonstrate substantial improvement over existing
therapies on one or more clinically significant endpoints, such as substantial treatment effects observed early in clinical development. Breakthrough
Therapy designation provides all the features of Fast Track designation in addition to intensive guidance on an efficient drug development program
beginning as early as Phase 1, and FDA organizational commitment to expedited development, including involvement of senior managers and experienced
review staff in a cross-disciplinary review, where appropriate.

Any product submitted to the FDA for approval, including a product with Fast Track or Breakthrough Therapy designation, may also be eligible for
additional FDA programs intended to expedite the review and approval process, including Priority Review designation and accelerated approval. A product
is eligible for Priority Review if it has the potential to provide a significant improvement in safety or effectiveness in the treatment, diagnosis or prevention
of a serious disease or condition. Under priority review, FDA will review an application in six months compared to ten months for a standard review.
Products are eligible for accelerated approval if they can be shown to have an effect on a surrogate endpoint that is reasonably likely to predict clinical
benefit, or an effect on a clinical endpoint that can be measured earlier than an effect on irreversible morbidity or mortality which is reasonably likely to
predict an effect on irreversible morbidity or mortality or other clinical benefit, taking into account the severity, rarity, or prevalence of the condition and
the availability or lack of alternative treatment. Accelerated approval is usually contingent on a sponsor’s agreement to conduct additional post-approval
studies to verify and describe the product’s clinical benefit. In addition, unless otherwise informed by the FDA, the FDA currently requires, as a condition
for accelerated approval, that all advertising and promotional materials that are intended for dissemination or publication be submitted to FDA for review
before the initial dissemination or publication.

Post-Approval Requirements

Any products manufactured or distributed by us pursuant to FDA approvals are subject to pervasive and continuing regulation by the FDA,
including, among other things, requirements relating to record-keeping, reporting of adverse experiences, periodic reporting, product sampling and
distribution, and advertising and promotion of the product. After approval, most changes to the approved product, such as adding new indications or other
labeling claims, are subject to prior FDA review and approval. There also are continuing user fee requirements, under which FDA assesses an annual
program fee for each product identified in an approved BLA. Biologic manufacturers and their subcontractors are required to register their establishments
with the FDA and certain state agencies, and are subject to periodic unannounced inspections by the FDA and certain state agencies for compliance with
cGMP, which impose certain procedural and documentation requirements upon us and our third-party manufacturers. 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 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.

39

 
The FDA may withdraw approval if compliance with regulatory requirements and standards is not maintained or if problems occur after the

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

•

•

•

•

•

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

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

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

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

injunctions or the imposition of civil or criminal penalties.

The FDA closely regulates the marketing, labeling, advertising and promotion of biologics. A company can make only those claims relating to
safety and efficacy, purity and potency that are approved by the FDA and in accordance with the provisions of the approved label. The FDA and other
agencies actively enforce the laws and regulations prohibiting the promotion of off-label uses. Failure to comply with these requirements can result in,
among other things, adverse publicity, warning letters, corrective advertising and potential civil and criminal penalties. Physicians may prescribe legally
available products for uses that are not described in the product’s labeling and that differ from those tested by us and approved by the FDA. Such off-label
uses are common across medical specialties. Physicians may believe that such off-label uses are the best treatment for many patients in varied
circumstances. The FDA does not regulate the behavior of physicians in their choice of treatments. The FDA does, however, restrict manufacturer’s
communications on the subject of off-label use of their products.

Biosimilars and Reference Product Exclusivity

The Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act of 2010 (collectively, the
“Affordable Care Act”), signed into law in 2010, includes a subtitle called the Biologics Price Competition and Innovation Act of 2009 (“BPCIA”), which
created an abbreviated approval pathway for biological products that are biosimilar to or interchangeable with an FDA-approved reference biological
product. To date, a number of biosimilars have been licensed under the BPCIA, and numerous biosimilars have been approved in Europe. The FDA has
issued several guidance documents outlining an approach to review and approval of biosimilars.

Biosimilarity, which requires that there be no clinically meaningful differences between the biological product and the reference product in terms of

safety, purity, and potency, can be shown through analytical studies, animal studies, and a clinical study or studies. Interchangeability requires that a
product is biosimilar to the reference product and the product must demonstrate that it can be expected to produce the same clinical results as the reference
product in any given patient and, for products that are administered multiple times to an individual, the biologic and the reference biologic may be
alternated or switched after one has been previously administered without increasing safety risks or risks of diminished efficacy relative to exclusive use of
the reference biologic. Complexities associated with the larger, and often more complex, structures of biological products, as well as the processes by
which such products are manufactured, pose significant hurdles to implementation of the abbreviated approval pathway that are still being worked out by
the FDA.

40

 
 
 
 
 
 
Under the BPCIA, an application for a biosimilar product may not be submitted to the FDA until four years following the date that the reference

product was first licensed by the FDA. In addition, the approval of a biosimilar product may not be made effective by the FDA until 12 years from the date
on which the reference product was first licensed. During this 12-year period of exclusivity, another company may still market a competing version of the
reference product if the FDA approves a full BLA for the competing product containing that applicant’s own preclinical data and data from adequate and
well-controlled clinical trials to demonstrate the safety, purity and potency of its product. The BPCIA also created certain exclusivity periods for
biosimilars approved as interchangeable products. At this juncture, it is unclear whether products deemed “interchangeable” by the FDA will, in fact, be
readily substituted by pharmacies, which are governed by state pharmacy law.

The BPCIA is complex and continues to be interpreted and implemented by the FDA. In addition, recent government proposals have sought to

reduce the 12-year reference product exclusivity period. Other aspects of the BPCIA, some of which may impact the BPCIA exclusivity provisions, have
also been the subject of recent litigation. As a result, the ultimate impact, implementation, and impact of the BPCIA is subject to significant uncertainty.

Other U.S. Healthcare Laws and Compliance Requirements

In the United States, our current and future operations are subject to regulation by various federal, state and local authorities in addition to the

FDA, including but not limited to, the Centers for Medicare & Medicaid Services (“CMS”), other divisions of the U.S. Department of Health and Human
Services (“HHS”) (such as the Office of Inspector General, Office for Civil Rights and the Health Resources and Service Administration), the U.S.
Department of Justice and state and local governments. For example, our clinical research, sales, marketing and scientific/educational grant programs may
have to comply with the anti-fraud and abuse provisions of the Social Security Act, the false claims laws, the privacy and security provisions of HIPAA,
and similar state laws, each as amended, as applicable.

The federal Anti-Kickback Statute prohibits, among other things, any person or entity from knowingly and willfully offering, paying, soliciting or

receiving any remuneration, directly or indirectly, overtly or covertly, in cash or in kind, to induce or in return for purchasing, leasing, ordering or arranging
for the purchase, lease or order of any item or service reimbursable, in whole or in part, under Medicare, Medicaid or other federal healthcare programs.
The term remuneration has been interpreted broadly to include anything of value. The Anti-Kickback Statute has been interpreted to apply to arrangements
between therapeutic product manufacturers on one hand and prescribers, purchasers, and formulary managers on the other. There are a number of statutory
exceptions and regulatory safe harbors protecting some common activities from prosecution. The exceptions and safe harbors are drawn narrowly and
practices that involve remuneration that may be alleged to be intended to induce prescribing, purchasing or recommending may be subject to scrutiny if
they do not qualify for an exception or safe harbor. Failure to meet all of the requirements of a particular applicable statutory exception or regulatory safe
harbor does not make the conduct per se illegal under the Anti-Kickback Statute. Instead, the legality of the arrangement will be evaluated on a case-by-
case basis based on a cumulative review of all of its facts and circumstances. Our practices may not in all cases meet all of the criteria for protection under
a statutory exception or regulatory safe harbor. The statutory exceptions and regulatory safe harbors are also subject to change.

Additionally, the intent standard under the Anti-Kickback Statute was amended by the Affordable Care Act, to a stricter standard such that a person

or entity no longer needs to have actual knowledge of the statute or specific intent to violate it in order to have committed a violation. In addition, the
Affordable Care Act also codified case law 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 federal FCA (discussed below).

41

 
The federal false claims laws, including the FCA, which imposes significant penalties and can be enforced by private citizens through civil qui tam

actions, and civil monetary penalty laws prohibit any person or entity from, among other things, knowingly presenting, or causing to be presented, a false
or fraudulent claim for payment to, or approval by, the federal government, including federal healthcare programs, such as Medicare and Medicaid;
knowingly making, using, or causing to be made or used a false record or statement material to a false or fraudulent claim to the federal government; or
knowingly making a false statement to improperly avoid, decrease or conceal an obligation to pay money to the federal government. A claim includes “any
request or demand” for money or property presented to the U.S. government. Although we would not submit claims directly to payors, manufacturers can
be held liable under these laws if they are deemed to “cause” the submission of false or fraudulent claims by, for example, providing inaccurate billing or
coding information to customers or promoting a product off-label. In addition, our future activities relating to the reporting of wholesaler or estimated retail
prices for our products, the reporting of prices used to calculate Medicaid rebate information and other information affecting federal, state, and third-party
reimbursement for our products, and the sale and marketing of our products, are subject to scrutiny under this law. For example, pharmaceutical companies
have been prosecuted under the FCA in connection with their alleged off-label promotion of drugs, purportedly concealing price concessions in the pricing
information submitted to the government for government price reporting purposes, and allegedly providing free product to customers with the expectation
that the customers would bill federal health care programs for the product.

HIPAA created additional federal criminal statutes that prohibit, among other things, knowingly and willfully executing, or attempting to execute, a

scheme to defraud or to obtain, by means of false or fraudulent pretenses, representations or promises, any money or property owned by, or under the
control or custody of, any healthcare benefit program, including private third-party payors, willfully obstructing a criminal investigation of a healthcare
offense, and knowingly and willfully falsifying, concealing or covering up by trick, scheme or device, a material fact or making any materially false,
fictitious or fraudulent statement in connection with the delivery of or payment for healthcare benefits, items or services. Like the Anti-Kickback Statute,
the Affordable Care Act amended the intent standard for certain healthcare fraud statutes under HIPAA such that a person or entity no longer needs to have
actual knowledge of the statute or specific intent to violate it in order to have committed a violation.

Also, many states have similar, and typically more prohibitive, fraud and abuse statutes or regulations that apply to items and services reimbursed

under Medicaid and other state programs, or, in several states, apply regardless of the payor.

In addition, we may be subject to data privacy, data security and data breach notification laws, regulations, standards, and codes of conduct by both

the U.S. federal government and the states. These laws, regulations, standards, and codes of conduct may govern the collection, use, disclosure and
protection of health-related and other personal information. HIPAA, as amended by the HITECH, imposes requirements relating to the privacy, security and
transmission of individually identifiable health information. HIPAA requires covered entities to limit the use and disclosure of protected health information
to specifically authorized situations, and requires covered entities to implement security measures to protect health information that they maintain in
electronic form. The federal government may impose civil, criminal, and administrative fines and penalties and/ or additional reporting or oversight
obligations for a violation of HIPAA’s requirements. Among other things, HITECH makes HIPAA’s privacy and security standards directly applicable to
business associates that receive or obtain protected health information in connection with providing a service on behalf of a covered entity.

HITECH also created four new tiers of civil monetary penalties, amended HIPAA to make civil and criminal penalties directly applicable to

business associates, and gave state attorneys general new authority to file civil actions for damages or injunctions in federal courts to enforce HIPAA and
seek attorneys’ fees and costs associated with pursuing federal civil actions. In addition to HIPAA and HITECH, many state laws govern the privacy and
security of health information in specified circumstances, many of which differ from each other in significant ways, are often not pre-empted by federal
law, and may have a more prohibitive effect than federal law, thus complicating compliance efforts.

42

 
We may develop products that, once approved, may be administered by a physician. Under currently applicable U.S. law, certain products not

usually self-administered (including injectable drugs) may be eligible for coverage under Medicare through Medicare Part B. Medicare Part B is the part of
Medicare that covers outpatient services and supplies, including certain pharmaceutical products, that are medically necessary to treat a beneficiary’s health
condition. As a condition of receiving Medicare Part B reimbursement for a manufacturer’s eligible drugs, the manufacturer is required to participate in
other government healthcare programs, including the Medicaid Drug Rebate Program and the 340B Drug Pricing Program. The Medicaid Drug Rebate
Program requires pharmaceutical manufacturers to enter into and have in effect a national rebate agreement with the Secretary of HHS as a condition for
states to receive federal matching funds for the manufacturer’s outpatient drugs furnished to Medicaid patients. Under the 340B Drug Pricing Program, the
manufacturer must extend discounts to entities that participate in the program.

In addition, many pharmaceutical manufacturers must calculate and report certain price reporting metrics to the government, such as average sales

price and best price. Penalties may apply in some cases when such metrics are not submitted accurately and timely.

Additionally, the federal Physician Payments Sunshine Act (the “Sunshine Act”) within the Affordable Care Act, and its implementing regulations,

require that certain manufacturers of drugs, devices, biological and medical supplies for which payment is available under Medicare, Medicaid or the
Children’s Health Insurance Program (with certain exceptions) report annually to CMS information related to certain payments or other transfers of value
made or distributed to physicians, as defined by such law, and teaching hospitals, or to entities or individuals at the request of, or designated on behalf of,
the physicians and teaching hospitals and to report annually certain ownership and investment interests held by physicians and their immediate family
members. This information is made publicly available on a CMS website, and failure to report accurately could result in penalties. In addition, many states
also govern the reporting of payments or other transfers of value, many of which differ from each other in significant ways, are often not pre-empted, and
may have a more prohibitive effect than the Sunshine Act, thus further complicating compliance efforts.

In order to distribute products commercially, we must comply with state laws that require the registration of manufacturers and wholesale
distributors of drug and biological products in a state, including, in certain states, manufacturers and distributors who ship products into the state even if
such manufacturers or distributors have no place of business within the state. Some states also impose requirements on manufacturers and distributors to
establish the pedigree of product in the chain of distribution, including some states that require manufacturers and others to adopt new technology capable
of tracking and tracing product as it moves through the distribution chain. Several state and local laws have been enacted requiring pharmaceutical and
biotechnology companies to establish marketing compliance programs, file periodic reports with the state, make periodic public disclosures on sales,
marketing, pricing, clinical trials and other activities, and/or register their sales representatives, as well as to prohibit pharmacies and other healthcare
entities from providing certain physician prescribing data to pharmaceutical and biotechnology companies for use in sales and marketing, and to prohibit
certain other sales and marketing practices. In addition, all of our activities are potentially subject to federal and state consumer protection and unfair
competition laws.

Ensuring business arrangements with third parties comply with applicable healthcare laws and regulations is a costly endeavor. If our operations

are found to be in violation of any of the federal and state healthcare laws described above or any other current or future governmental regulations that
apply to us, we may be subject to significant penalties, including without limitation, civil, criminal and/or administrative penalties, damages, fines,
disgorgement, imprisonment, exclusion from participation in government programs, such as Medicare and Medicaid, injunctions, private “qui tam” actions
brought by individual whistleblowers in the name of the government, or refusal to allow us to enter into government contracts, contractual damages,
reputational harm, administrative burdens, diminished profits and future earnings, additional reporting obligations and oversight if we become subject to a
corporate integrity agreement or other agreement to resolve allegations of non-compliance with these laws, 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.

43

 
Coverage, Pricing and Reimbursement

Significant uncertainty exists as to the coverage and reimbursement status of any product candidates for which we may obtain regulatory approval.
In the United States and in foreign markets, sales of any products for which we receive regulatory approval for commercial sale will depend, in part, on the
extent to which third-party payors provide coverage and establish adequate reimbursement levels for such products. In the United States, third-party payors
include federal and state healthcare programs, private managed care providers, private health insurers and other organizations. Adequate coverage and
reimbursement from governmental healthcare programs, such as Medicare and Medicaid in the United States, and commercial payors are critical to new
product acceptance.

Our ability to commercialize any products successfully also will depend in part on the extent to which coverage and adequate reimbursement for
these products and related treatments will be available from government health administration authorities, private health insurers and other organizations.
Government authorities and third-party payors, such as private health insurers and health maintenance organizations, decide which therapeutics they will
pay for and establish reimbursement levels. Coverage and reimbursement by a third-party payor may depend upon a number of factors, including the third-
party payor’s determination that use of a therapeutic is:

•

•

•

•

•

a covered benefit under its health plan;

safe, effective and medically necessary;

appropriate for the specific patient;

cost-effective; and

neither experimental nor investigational.

We cannot be sure that reimbursement will be available for any product that we commercialize and, if coverage and reimbursement are available,

what the level of reimbursement will be. Coverage may also be more limited than the purposes for which the product is approved by the FDA or
comparable foreign regulatory authorities. Reimbursement may impact the demand for, or the price of, any product for which we obtain regulatory
approval.

Third-party payors are increasingly challenging the price, examining the medical necessity, and reviewing the cost-effectiveness of medical
products, therapies and services, in addition to questioning their safety and efficacy. Obtaining reimbursement for our products may be particularly difficult
because of the higher prices often associated with branded drugs and drugs administered under the supervision of a physician. 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. Obtaining coverage and reimbursement
approval of a product from a government or other third-party payor is a time-consuming and costly process that could require us to provide to each payor
supporting scientific, clinical and cost-effectiveness data for the use of our product on a payor-by-payor basis, with no assurance that coverage and
adequate reimbursement will be obtained. A payor’s decision to provide coverage for a product does not imply that an adequate reimbursement rate will be
approved. Further, one payor’s determination to provide coverage for a product does not assure that other payors will also provide coverage for the product.
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. If reimbursement is not available or is available only at limited levels, we may not be able to successfully commercialize any
product candidate that we successfully develop.

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 has become 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.

44

 
 
 
 
 
 
The marketability of any product candidates 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, emphasis on managed care, the increasing influence of health maintenance
organizations, and additional legislative changes in the United States has increased, and we expect will continue to increase, the pressure on healthcare
pricing. The downward pressure on the rise in healthcare costs in general, particularly prescription medicines, medical devices and surgical procedures and
other treatments, has become very intense. 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.

Healthcare Reform

In the United States and some foreign jurisdictions, there have been, and continue to be, several legislative and regulatory changes and proposed

changes regarding the healthcare system that could prevent or delay marketing approval of product candidates, restrict or regulate post-approval activities,
and affect the ability to profitably sell product candidates for which marketing approval is obtained. Among policy makers and payors in the United States
and elsewhere, there is significant interest in promoting changes in healthcare systems with the stated goals of containing healthcare costs, improving
quality and/or expanding access. In the United States, the pharmaceutical industry has been a particular focus of these efforts and has been significantly
affected by major legislative initiatives.

For example, the Affordable Care Act has substantially changed healthcare financing and delivery by both governmental and private insurers. The

Affordable Care Act and its implementing regulations, among other things, revised the methodology for calculating rebates for covered outpatient drugs
and certain biologics owed by manufacturers to the state and federal government under the Medicaid Drug Rebate Program, increased the minimum
Medicaid rebates owed by most manufacturers under the Medicaid Drug Rebate Program, extended the Medicaid Drug Rebate program to utilization of
prescriptions of individuals enrolled in Medicaid managed care organizations, subjected manufacturers to new annual fees and taxes for certain branded
prescription drugs, and expanded programs designed to test innovative payment models, service delivery models, or value-based arrangements, and fund
comparative effectiveness research.

There remain legal and political challenges to certain aspects of the Affordable Care Act. Since January 2017, President Trump has signed
executive orders and other directives designed to delay, circumvent or loosen certain requirements mandated by the Affordable Care Act. On December 22,
2017, President Trump signed into law the Tax Cuts and Jobs Act of 2017 (the “Tax Act”), which included a provision that repealed the tax penalty for an
individual’s failure to maintain Affordable Care Act-mandated health insurance, effective January 1, 2019.

Further, the 2020 federal spending package permanently eliminated, effective January 1, 2020, the Affordable Care Act’s mandated “Cadillac” tax

on high-cost employer-sponsored health coverage and medical device tax and, effective January 1, 2021, also eliminates the health insurer tax.

Moreover, the Bipartisan Budget Act of 2018 (the “BBA”) among other things, amended the Affordable Care Act, effective January 1, 2019, to
close the coverage gap in most Medicare drug plans, commonly referred to as the “donut hole.” Additionally, in December 2018, CMS published a final
rule permitting further collections and payments to and from certain Affordable Care Act qualified health plans and health insurance issuers under the
Affordable Care Act risk adjustment program in response to the outcome of federal district court litigation regarding the method CMS uses to determine
this risk adjustment.

On December 14, 2018, a United States District Court judge in Texas ruled that the Affordable Care Act is unconstitutional in its entirety because

the “individual mandate” was repealed by Congress as part of the Tax Cuts and Jobs Act of 2017. The decision was been appealed to the United States
Court of Appeals for the Fifth Circuit and on December 18, 2019, the United States Court of Appeals for the Fifth Circuit upheld the District Court’s ruling
that the individual mandate was unconstitutional, but remanded the case back to the District Court to determine whether the remaining provisions of the
Affordable Care Act were nonetheless valid. On March 2, 2020, the United States Supreme Court granted the petitions for writs of certiorari to review this
case, and has allotted one hour for oral arguments, which are expected to occur in the fall. It is unclear how such litigation and other efforts to repeal and
replace the Affordable Care Act will impact the Affordable Care Act.

45

 
We anticipate that the Affordable Care Act, if substantially maintained in its current form, will continue to result in additional downward pressure

on coverage and the price that we receive for any approved product, and could seriously harm our business. Any reduction in reimbursement from
Medicare and other government programs may result in a similar reduction in payments from private payors. The implementation of cost containment
measures or other healthcare reforms may prevent us from being able to generate revenue, attain profitability, or commercialize our products. Such reforms
could have an adverse effect on anticipated revenue from product candidates that we may successfully develop and for which we may obtain regulatory
approval and may affect our overall financial condition and ability to develop product candidates.

In addition, further legislation or regulation could be passed that could harm our business, financial condition and results of operations. Other
legislative changes have been proposed and adopted since the Affordable Care Act was enacted. For example, in August 2011, President Obama signed into
law the Budget Control Act of 2011, which, among other things, created the Joint Select Committee on Deficit Reduction to recommend to Congress
proposals in spending reductions. The Joint Select Committee on Deficit Reduction did not achieve a targeted deficit reduction of at least $1.2 trillion for
fiscal years 2012 through 2021, triggering the legislation’s automatic reduction to several government programs. This includes aggregate reductions to
Medicare payments to providers of up to 2% per fiscal year, which went into effect beginning on April 1, 2013 and which, under the Bipartisan Budget Act
of 2019, have been extended through 2029, subject to additional Congressional action. In January 2013, the American Taxpayer Relief Act of 2012 was
signed into law, which, among other things, further reduced Medicare payments to several types of providers, including hospitals, imaging centers and
cancer treatment centers, and increased the statute of limitations period for the government to recover overpayments to providers from three to five years.

Additionally, there has been increasing legislative and enforcement interest in the United States with respect to specialty drug pricing practices.

Specifically, there have been several recent U.S. Congressional inquiries and proposed federal legislation designed to, among other things, bring more
transparency to drug pricing, reduce the cost of prescription drugs under Medicare, review the relationship between pricing and manufacturer patient
programs, and reform government program reimbursement methodologies for drugs. At the federal level, the Trump administration’s budget proposal for
fiscal year 2021 includes a $135 billion allowance to support legislative proposals seeking to reduce drug prices, increase competition, lower out-of-pocket
drug costs for patients, and increase patient access to lower-cost generic and biosimilar drugs. On March 10, 2020, the Trump administration sent
“principles” for drug pricing to Congress, calling for legislation that would, among other things, cap Medicare Part D beneficiary out-of-pocket pharmacy
expenses, provide an option to cap Medicare Part D beneficiary monthly out-of-pocket expenses, and place limits on pharmaceutical price increases.
Previously, the Trump administration released a “Blueprint,” or plan, to lower drug prices and reduce out of pocket costs of drugs that contained proposals
to increase drug manufacturer competition, increase the negotiating power of certain federal healthcare programs, incentivize manufacturers to lower the
list price of their products, and reduce the out of pocket costs of drug products paid by consumers.

HHS has solicited feedback on some of these measures and has implemented others under its existing authority. For example, in May 2019, CMS

issued a final rule to allow Medicare Advantage plans the option to use step therapy for Part B drugs beginning January 1, 2020. This final rule codified
CMS’s policy change that was effective January 1, 2019.  Further, in December 2019, the FDA issued draft guidance describing procedures for drug
manufacturers to facilitate the importation of FDA-approved drugs and biologics manufactured abroad and originally intended for sale in a foreign country
into the United States. President Trump’s administration has also proposed to establish an international pricing index that would tie domestic prices for
certain drugs and biologics to the prices in other countries. While some proposed measures may require additional authorization through additional
legislation to become effective, Congress and the Trump administration have each indicated that it will continue to seek new legislative and/or
administrative measures to control drug costs.

46

 
Individual states in the United States have also become increasingly active in passing legislation and implementing regulations designed to control

pharmaceutical product pricing, including price or patient reimbursement constraints, discounts, restrictions on certain product access and marketing cost
disclosure and transparency measures, and, in some cases, designed to encourage importation from other countries and bulk purchasing. For example, after
some pharmacy benefit managers and insurers adopted policies stating that the amount of a copay coupon would not be applied to the enrollee’s deductible
or out-of-pocket maximum (referred to as “accumulator adjustment programs”), some states passed legislation banning these policies. On January 31, 2020,
CMS released its proposed 2021 Notice of Benefit and Payment Parameters rule, which provides that insurers would no longer be required to count any
coupons from drug manufacturers towards a consumer’s out-of-pocket limit. The implementation of cost containment measures or other healthcare reforms
may prevent us from being able to generate revenue, attain profitability, or commercialize our product candidates, if approved.

Additional Regulation

In addition to the foregoing, local, state and federal laws, including in the United States and Israel, regarding such matters as safe working
conditions, manufacturing practices, environmental protection, fire hazard control and hazardous substances, including the Occupational Safety and Health
Act, the Resource Conservancy and Recovery Act and the Toxic Substances Control Act, affect our business. These and other laws govern our use,
handling and disposal of various biological, chemical and radioactive substances used in, and wastes generated by, our operations. If our operations result
in contamination of the environment or expose individuals to hazardous or biohazardous substances, we could be liable for damages, environmental
remediation, and/or governmental fines. We believe that we are in material compliance with applicable environmental laws and occupational health and
safety laws that continued compliance therewith will not have a material adverse effect on our business. We cannot predict, however, how changes in these
laws may affect our future operations. We may incur significant costs to comply with such laws and regulations now or in the future.

Competition

The biopharmaceutical industry is intensely competitive and subject to rapid innovation and significant technological advancements. We believe
the key competitive factors that will affect the development and commercial success of BIO89-100 and any future product candidates are efficacy, safety
and tolerability profile, reliability, convenience of dosing, price, the level of generic competition and reimbursement. Our competitors include multinational
pharmaceutical companies, specialized biotechnology companies, universities and other research institutions. A number of biotechnology and
pharmaceutical companies are pursuing the development or marketing of pharmaceuticals that target the same diseases that we are targeting. Smaller or
earlier-stage companies may also prove to be significant competitors, particularly through collaborative arrangements with large, established companies.
Given the high incidence of NASH, it is likely that the number of companies seeking to develop products and therapies for the treatment of liver and
cardio-metabolic diseases, such as NASH, will increase.

If BIO89-100 is approved for the treatment of NASH, future competition could also arise from products currently in development, including:
cenicriviroc, an immunomodulator that blocks CCR2 and CCR5 from Allergan plc; GS-0976, an ACC inhibitor, and GS-9674, an FXR agonist, from
Gilead Sciences, Inc.; PF-05221304, an ACC inhibitor, and PF-06835919, a KHK inhibitor, from Pfizer Inc.; Ocaliva, an FXR agonist from Intercept
Pharmaceuticals, Inc.; resmetirom, a beta-thyroid hormone receptor agonist from Madrigal Pharmaceuticals, Inc.; VK2809, a beta-thyroid hormone
receptor agonist from Viking Therapeutics, Inc.; aldfermin, an FGF19 analog from NGM Biopharmaceuticals, Inc.; MK-3655, an FGFR1c/KLB agonist
antibody from Merck & Co., Inc.; pegbelfermin, a PEGylated FGF21 analog from Bristol-Myers Squibb Company; AKR-001, a FGF21 fusion protein
from Akero Therapeutics, Inc.; elobixibat, an IBAT-inhibitor from Albireo Pharma, Inc.; a Galectin-3 inhibitor from Galectin Therapeutics Inc.; a synthetic
conjugate of cholic acid and arachidic acid from Galmed Pharmaceuticals Ltd.; an FXR agonist from Metacrine, Inc.; FXR agonists from Novartis AG; a
mitochondrial pyruvate complex modulator from Cirius Therapeutics, Inc.; semaglutide, a GLP-1 receptor agonist from Novo Nordisk A/S; tirzepatide, a
dual IP/GLP-1 receptor agonist from Eli Lilly and Company; and elafibranor, a PPAR alpha/delta agonist from Genfit S.A.

47

 
If BIO89-100 is approved for the treatment of SHTG, we would face competition from currently approved and marketed products, including
statins, fibrates, Vascepa, Epanova and Lovaza, as well as generic products. Further competition could arise from products currently in development,
including: AKCEA-APOCIII-LRx, an ApoC III inhibitor and AKCEA-ANGPTL3, an anti-ANGPTL3 from Akcea Therapeutics, Inc.; evinacumab, an
Anti-ANGPTL3 from Regeneron Pharmaceuticals, Inc.; pemafibrate, a PPAR alpha agonist from Kowa Research Institute, Inc.; gemcabene; CaPre, an
omega-3 fatty acid from Acasti Pharma Inc.; and ARO-APOC3, an ApoC III inhibitor and ARO-ANG3, an anti-ANGPTL3 from Arrowhead
Pharmaceuticals, Inc.

Many of our competitors have substantially greater financial, technical, human and other resources than we do and may be better equipped to

develop, manufacture and market technologically superior products. In addition, many of these competitors have significantly longer operating histories
and greater experience than we have in undertaking nonclinical studies and human clinical trials of new pharmaceutical products and in obtaining
regulatory approvals of human therapeutic products. Many of our competitors have established distribution channels for the commercialization of their
products, whereas we have no such channel or capabilities. In addition, many competitors have greater name recognition and more extensive collaborative
relationships. As a result, our competitors may obtain regulatory approval of their products more rapidly than we do or may obtain patent protection or
other intellectual property rights that limit our ability to develop or commercialize our product candidate or any future product candidates. Our competitors
may also develop and succeed in obtaining approval for drugs that are more effective, more convenient, more widely used and less costly or have a better
safety profile than our products and these competitors may also be more successful than we are in manufacturing and marketing their products. If we are
unable to compete effectively against these companies, then we may not be able to commercialize our product candidate or any future product candidates or
achieve a competitive position in the market. This would adversely affect our ability to generate revenue. Our competitors also compete with us in
recruiting and retaining qualified scientific, management and commercial personnel, establishing clinical trial sites and enrolling patients for clinical trials,
as well as in acquiring technologies complementary to, or necessary for, our programs.

Manufacturing and Supply

We do not own or operate manufacturing facilities for the production of BIO89-100, nor do we have plans to develop our own manufacturing

operations in the foreseeable future. We currently rely, and expect to continue to rely, on third parties for the manufacturing of our product candidates for
preclinical and clinical testing, as well as for commercial manufacturing if BIO89-100 or any future product candidate receives marketing approval.

BIO89-100 drug substance is manufactured by fermentation of a recombinant strain of the bacterium E. coli. Product accumulates as insoluble
particles (inclusion bodies) within the cells and is recovered by cell disruption, followed by solubilization of the inclusion bodies, protein refolding and
purification with two chromatographic separation columns. Purified material is glycoPEGylated in a 2-step enzymatic reaction where a 20kDa linear
glycoPEG moiety is attached to the protein through GalNAc and Sialic Acid linkers.

GlycoPEGylated protein is purified with two chromatographic columns to yield product with target quality attributes. Purified glycoPEGylated

protein is concentrated and then formulated to a target concentration with formulation buffer as drug product.

BTPH is our sole source supplier for BIO89-100. While any reduction or halt in supply of drug product from BTPH could limit our ability to
develop BIO89-100 until a replacement contract manufacturer is found and qualified, we have recently produced several batches to support toxicology and
clinical studies. We currently have material available to support our ongoing Phase POC 1b/2a trial of BIO89-100 for the treatment of NASH and for our
SHTG trial.

We are working with BTPH on process optimization to support large-scale production for future trials and commercialization. In parallel, we have
entered into a contract with a formulation development company to explore the potential for a new refrigerated liquid formulation and/or a freeze-dried, or
lyophilized product.

48

 
BTPH Agreement

On May 7, 2018, we entered into a master services agreement with BTPH, under which BTPH agreed to provide us certain services, including the

manufacturing, packaging, labeling and storing of BIO89-100, under statements of work for such services to be agreed by the parties from time to time.
The master services agreement will continue for the duration of time that BTPH is providing services to us, unless earlier terminated by either party upon
its terms. We may terminate the agreement at any time after a specified notice period and subject to the payment of certain agreed upon fees where such
termination results in cancellation of manufacturing scheduled within a certain period. In addition, either party may terminate the agreement for cause for
the other party’s uncured material breach, in the event of bankruptcy of the other party, in the event of the commission of fraud by the other party or in the
event of a force majeure.

Sales and Marketing

We currently have no marketing, sales or distribution capabilities. In order to commercialize any products that are approved for commercial sale,

we must either develop a sales and marketing infrastructure or collaborate with third parties that have sales and marketing experience.

We may elect to establish our own sales force to market and sell a product for which we obtain regulatory approval if we expect that the geographic

market for a product we develop on our own is limited or that the prescriptions for the product will be written principally by a relatively small number of
physicians. If we decide to market and sell any products ourselves, we do not expect to establish direct sales capability until shortly before the products are
approved for commercial sale.

We plan to seek third-party support from established pharmaceutical and biotechnology companies for those products that would benefit from the

promotional support of a large sales and marketing force. In these cases, we might seek to promote our products in collaboration with marketing partners or
rely on relationships with one or more companies with large established sales forces and distribution systems.

Intellectual Property

Our success depends in part upon our ability to protect our core technology and intellectual property. To protect our intellectual property rights, we

rely on patents, trademarks, copyrights and trade secret laws, confidentiality procedures, and employee disclosure and invention assignment agreements.
Our intellectual property is critical to our business and we strive to protect it through a variety of approaches, including by obtaining and maintaining patent
protection in the United States and internationally for our product candidates, novel biological discoveries, new targets and applications, and other
inventions that are important to our business. For our product candidates, we generally intend to pursue patent protection covering compositions of matter,
methods of making and methods of use. As we continue the development of our product candidates, we plan to identify additional means of obtaining
patent protection that would potentially enhance commercial success, including pursuit of claims directed to new therapeutic indications.

FGF21 Patents

Our FGF21 patent portfolio includes two families: the first is entitled “Remodeling and GlycoPEGylation of Fibroblast Growth Factor (FGF)” and
the second is entitled “Mutant FGF-21 Peptide Conjugate and Uses Thereof.” The first family provides granted patent protection in 39 countries around the
globe, including the United States (U.S. Patent Number 9,200,049; expiry June 25, 2028), Canada, Europe (broadly), and Japan (latter three expire October
31, 2025) for FGF21 conjugates comprising a variety of modifying groups that can be attached at several different amino acid positions. GlycoPEGylated
FGF21 is specifically claimed. The granted claims broadly protect our lead drug candidate BIO89-100 and pharmaceutical compositions thereof, as well as
methods for making and using BIO89-100 to treat FGF21 deficiency in a patient in need thereof. One U.S. application is pending in this family.

49

 
The second family is specifically directed to BIO89-100. The progenitor PCT Application for this family was filed on September 4, 2018
(PCT/IB2018/00112). A U.S. Prioritized Examination Continuation Patent Application (Application Serial No. 16/225,640) was filed on December 19,
2018 as a continuation of PCT/IB2018/0112 and from which U.S. Patent Number 10,407,479 issued on September 10, 2019. The term of the U.S. Patent
Number 10,407,479 is September 4, 2038. The issued claims are directed to BIO89-100 and a defined genus specifically encompassing BIO89-100 and
compositions thereof (including site-specific mutations at positions 173 and 176), as well as methods for making and using BIO89-100 for a variety of
therapeutic indications. Such indications include methods for treating NASH or metabolic syndrome. Subjects wherein there is a need to reduce blood
glucose or to reduce HbA1C include those afflicted with diabetes Type 2, NASH and metabolic syndrome. The claims encompass different therapeutic
regimens for administering BIO89-100 (e.g., once a week or once every two weeks), which regimens are based on BIO89-100’s surprisingly long half-life
in vivo.

National phase entry of this PCT Application in March of 2020 provides the opportunity to pursue global protection of specific mutant FGF21
peptide conjugates, and particularly BIO89-100. National phase entry has been initiated in Europe, China, Japan, Australia, Canada, Israel and Korea.

FASN Patents

Our FASN patent portfolio currently consists of three patent families, including patents and/or patent applications in the United States, the

European Patent Convention, Canada, Mexico, Israel and Japan.

The first patent family, directed to TEV-48317, which we acquired from Teva under the FASN Agreement, and other 1,4-substituted piperidine-

based FASN inhibitors, is currently protected by two granted U.S. patents that cover these compounds, pharmaceutical compositions comprising these
compounds, and methods of treating FASN-mediated disorders using these compounds. The non-extended term for these patents would expire on June 17,
2036. A pending U.S. application is directed to additional methods of treatment using these compounds. The second patent family is directed to other 1,4-
substituted piperidine-based FASN inhibitors, pharmaceutical compositions, and methods of treating FASN-mediated disorders. The third patent family is
directed to spiropiperidine FASN inhibitors, pharmaceutical compositions containing these compounds, and methods of treating FASN-mediated disorders
using these compounds.

Employees

As of December 31, 2019, we had 19 full-time employees and 20 total employees. 14 employees are engaged in research and development
activities. None of our employees are represented by labor unions or covered by collective bargaining agreements. We consider our relationship with our
employees to be good.

Corporate Information

We were incorporated in January 2018 in Israel under the name 89Bio Ltd. 89bio, Inc., the registrant whose name appears on the cover page of this
Annual Report on Form 10-K, was incorporated in June 2019 for the purpose of an internal reorganization transaction. In September 2019, all of the equity
holders of 89Bio Ltd. exchanged 100% of the equity of 89Bio Ltd. for 100% of the equity of 89bio, Inc. Following this exchange, 89Bio Ltd. became a
wholly owned subsidiary of 89bio, Inc.

Our principal executive offices are located at 142 Sansome Street, San Francisco, California 94104 and our telephone number is (415) 500-4614.

Our website is www.89bio.com. Information contained on or accessible through our website is not a part of this Annual Report on Form 10-K, and the
inclusion of our website address in this Annual Report on Form 10-K is an inactive textual reference only.

We file electronically with the SEC our Annual Report on Form 10-K, Quarterly Reports on Form 10-Q, Current Reports on Form 8-K and

amendments to those reports filed or furnished pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934, as amended (the “Exchange
Act”). We make available on our website at www.89bio.com, under “Investors,” free of charge, copies of these reports as soon as reasonably practicable

Implications of Being an Emerging Growth Company and a Smaller Reporting Company

We are an emerging growth company (“emerging growth company”), as defined in Section 2(a) of the Securities Act of 1933, as amended (the

“Securities Act”), as modified by the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”), and we may take advantage of certain exemptions
from various reporting requirements that are applicable to other public companies that are not emerging growth companies, including relief from the
auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002, as amended, less extensive disclosure obligations regarding executive
compensation in our registration statements, periodic reports and proxy statements, exemptions from the requirements to hold a nonbinding advisory vote
on executive compensation, and exemptions from stockholder approval of any golden parachute payments not previously approved. We may also elect to
take advantage of other reduced reporting requirements in future filings. As a result, our stockholders may not have access to certain information that they
may deem important and the information that we provide to our stockholders may be different than, and not comparable to, information presented by other
public reporting companies. We could remain an emerging growth company until the earlier of (1) the last day of the year following the fifth anniversary of
the completion of our initial public offering (“IPO”), (2) the last day of the year in which we have total annual gross revenue of at least $1.07 billion, (3)
the last day of the year in which we are deemed to be a “large accelerated filer” as defined in Rule 12b-2 under the Exchange Act, which would occur if the
market value of our common stock held by non-affiliates exceeded $700.0 million as of the last business day of the second fiscal quarter of such year or (4)
the date on which we have issued more than $1.0 billion in non-convertible debt securities during the prior three-year period.

In addition, the JOBS Act also provides that an emerging growth company may take advantage of the extended transition period provided in the

Securities Act for complying with new or revised accounting standards. An emerging growth company may therefore delay the adoption of certain
accounting standards until those standards would otherwise apply to private companies. We have elected to avail ourselves of this exemption and, as a
result, will not be subject to the same implementation timing for new or revised accounting standards as are required of other public companies that are not
emerging growth companies, which may make comparison of our consolidated financial information to those of other public companies more difficult.

We are also a smaller reporting company (“smaller reporting company”), as defined in the Exchange Act. We may continue to be a smaller

reporting company even after we are no longer an emerging growth company. We may take advantage of certain of the scaled disclosures available to
smaller reporting companies and will be able to take advantage of these scaled disclosures for so long as (i) our voting and non-voting common stock held
by non-affiliates is less than $250.0 million measured on the last business day of our second fiscal quarter or (ii) our annual revenue is less than $100.0
million during the most recently completed fiscal year and our voting and non-voting common stock held by non-affiliates is less than $700.0 million
measured on the last business day of our second fiscal quarter.

Item 1A. Risk Factors.

An investment in our common stock involves a high degree of risk. You should carefully consider the risks and uncertainties described below before

deciding whether to make an investment decision with respect to shares of our common stock. You should also refer to the other information contained in
this Annual Report on Form 10-K, including “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and our audited
consolidated financial statements and related notes. Our business, financial condition, results of operations and prospects could be materially and
adversely affected by any of these risks or uncertainties. In any such case, the trading price of our common stock could decline, and you could lose all or
part of your investment. We caution you that the risks, uncertainties and other factors referred to below and elsewhere in this Annual Report on Form 10-K
may not contain all of the risks, uncertainties and other factors that may affect our future results and operations. Moreover, new risks will emerge from time
to time. It is not possible for our management to predict all risks.

Risks Related to Our Business and Industry

We are a clinical-stage biopharmaceutical company with a limited operating history and no products approved  for commercial sale. We have incurred
net losses since our inception, we expect to incur significant and increasing operating losses and we may never be profitable. Our stock is a highly
speculative investment.

We are a clinical-stage biopharmaceutical company with a limited operating history that may make it  difficult to evaluate the success of our

business to date and to assess our future viability. We commenced operations in 2018, and to date, our operations have been limited to organizing and
staffing our company, business planning, raising capital, acquiring our initial product candidate, BIO89-100 and licensing certain related technology,
conducting research and development activities, including preclinical studies and early  clinical trials, and providing general and administrative support for
these operations. Investment in biopharmaceutical product development is highly speculative because it entails substantial upfront capital expenditures and
significant risk that any potential product candidate will fail to demonstrate adequate effect and/ or an acceptable safety profile, gain regulatory approval
and become commercially viable. We have no products approved for commercial sale, we have not generated any revenue from product sales to date and
we continue to incur significant research and development and other expenses related to our ongoing operations. We have limited experience as a company
conducting clinical trials and no experience as a company commercializing any products.

We are not profitable and have incurred net losses since our inception. As of December 31, 2019, we had an accumulated deficit of $73.6 million.
Consequently, predictions about our future success or viability may not be as accurate as they would be if we had a longer operating history or a history of
successfully developing and commercializing pharmaceutical products. We have spent, and expect to continue to spend, significant resources to fund
research and development of, and seek regulatory approvals for, BIO89-100 and any future product candidates. We expect to incur substantial and
increasing operating losses over the next several years as our research, development, preclinical testing and clinical trial activities increase. As a result, our
accumulated deficit will also increase significantly. We may encounter unforeseen expenses, difficulties, complications, delays and other unknown factors
that may adversely affect our business. The size of our future net losses will depend, in part, on the rate of future growth of our expenses and our ability to
generate revenue. Our prior losses and expected future losses have had and will continue to have an adverse effect on our stockholders’ equity (deficit) and
working capital. The net losses we incur may fluctuate significantly from quarter-to-quarter such that a period-to-period comparison of our results of
operations may not be a good indication of our future performance. Even if we eventually generate product revenue, we may never be profitable and, if we
do achieve profitability, we may not be able to sustain or increase profitability on a quarterly or annual basis.

52

 
We currently have no source of product revenue and may never become profitable.

BIO89-100 is in the early stages of development. To date, we have not generated any revenue from the licensing or commercialization of BIO89-

100. We will not be able to generate product revenue unless and until BIO89-100 or any future product candidate, alone or with future partners,
successfully completes clinical trials, receives regulatory approval and is successfully commercialized. As BIO89-100 is in the early stages of
development, we do not expect to receive revenue from it for a number of years, if ever. Although we may seek to obtain revenue from collaboration or
licensing agreements with third parties, we currently have no such  agreements that could provide us with material, ongoing future revenue and we may
never enter into any such agreements. Our ability to generate future product revenue from BIO89-100 or any future product candidates also depends on a
number of additional factors, including our or our future partners’ ability to:

•

•

•

•

•

•

•

•

successfully complete research and clinical development of BIO89-100 and any future product candidates;

establish and maintain supply and manufacturing relationships with third parties, and ensure adequate and legally compliant manufacturing
of bulk drug substances and drug products to maintain that supply;

launch and commercialize future product candidates for which we obtain marketing approval, if any, and, if launched independently,
successfully establish a sales force, marketing and distribution infrastructure;

demonstrate the necessary safety data post-approval to ensure continued regulatory approval;

obtain coverage and adequate product reimbursement from third-party payors, including government payors;

achieve market acceptance for our or our future partners’ products, if any;

establish, maintain, protect and enforce our intellectual property rights; and

attract, hire and retain qualified personnel.

In addition, because of the numerous risks and uncertainties associated with pharmaceutical product development, including that our product

candidates may not advance through development or achieve the endpoints of applicable clinical trials, we are unable to predict the timing or amount of
increased expenses, or if or when we will achieve or maintain profitability. In addition, our expenses could increase beyond expectations if we decide, or
are required by the FDA or comparable foreign regulatory authorities, to perform studies or trials in addition to those that we currently anticipate. Even if
we complete the development and regulatory processes described above, we anticipate incurring significant costs associated with launching and
commercializing these products.

Even if we generate revenue from the sale of any of our product candidates that may be approved, we may not become profitable and may need to

obtain additional funding to continue operations. If we fail to become profitable or do not sustain profitability on a continuing basis, then we may be unable
to continue our operations at planned levels and be forced to reduce our operations.

We will require substantial additional capital to finance our operations, which may not be available to us on acceptable terms, or at all. As a result, we
may not complete the development and commercialization of BIO89-100 or develop new product candidates.

As a clinical-stage biopharmaceutical company, our operations have consumed significant amounts of  cash since our inception. We expect our

research and development expenses to increase substantially in connection with our ongoing activities, particularly as we conduct our Phase 1b/2a clinical
trial and future clinical trials of BIO89-100 and seek regulatory approvals for BIO89-100.

We believe that the net proceeds from our IPO, together with our existing cash and cash equivalents will fund our projected operating requirements into

the second half of 2021. Our forecast of the period of time through which our financial resources will adequately support our operations is a forward-looking
statement and involves risks and uncertainties, and actual results could vary as a result of a number of factors, including the factors discussed elsewhere in this
“Risk Factors” section. We have based this estimate on assumptions that may prove to be wrong, and we could utilize our available capital resources sooner
than we currently expect. Our future funding requirements, both short and long-term, will depend on many factors, including:

•

•

•

•

•

•

•

•

the initiation, progress, timing, costs and results of preclinical and clinical studies for BIO89-100 and any future product candidates we
may develop;

the outcome, timing and cost of seeking and obtaining regulatory approvals from the FDA and comparable foreign regulatory authorities,
including the potential for such authorities to require that we perform more studies than those that we currently expect or change their
requirements on studies that had previously been agreed to;

the cost to establish, maintain, expand, enforce and defend the scope of our intellectual property portfolio, including the amount and timing
of any payments we may be required to make, or that we may receive, in connection with licensing, preparing, filing, prosecuting,
defending and enforcing of any patents or other intellectual property rights;

the effect of competing technological and market developments;

market acceptance of any approved product candidates, including product pricing and product coverage and adequate reimbursement by
third-party payors;

the cost of acquiring, licensing or investing in additional businesses, products, product candidates and technologies;

the cost and timing of selecting, auditing and potentially validating a manufacturing site for commercial-scale manufacturing of BIO89-
100; and

the cost of establishing sales, marketing and distribution capabilities for BIO89-100 and any future product candidates for which we may
receive regulatory approval and that we determine to commercialize ourselves or in collaboration with our future partners.

We will require additional capital to discover, develop, obtain regulatory approval for and commercialize BIO89-100 and any future product
candidates. We do not have any committed external source of funds. We expect to finance future cash needs through public or private equity or debt
offerings or product collaborations. Additional capital may not be available in sufficient amounts or on reasonable terms, if at all. If we do not raise
additional capital, we may not be able to expand our operations or otherwise capitalize on our business opportunities, our business and financial condition
will be negatively impacted and we may need to:

•

•

•

•

significantly delay, scale back or discontinue research and discovery efforts and the development or commercialization of any product
candidates or cease operations altogether;

seek strategic alliances for research and development programs when we otherwise would not, or at an earlier stage than we would
otherwise desire or on terms less favorable than might otherwise be available; or

relinquish, or license on unfavorable terms, our rights to technologies or any product candidates that we otherwise would seek to develop or
commercialize ourselves.

In addition, if BIO89-100 receives approval and is commercialized, we will be required to make milestone and royalty payments to Teva,
from whom we acquired certain patents and intellectual property relating to BIO89-100, and from whom we licensed patents and know-
how related to glycoPEGylation technology that is used in the manufacture of BIO89-100. For additional information regarding this license
agreement, please see the section titled “Business—Agreements with Teva” and Note 5 to our consolidated financial statements
accompanying this Annual Report on Form 10-K.

54

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

Existing stockholders could suffer dilution or be negatively affected by fixed payment obligations we may incur if we raise additional funds

through the issuance of additional equity securities or debt. Furthermore,  these securities may have rights senior to those of our common stock and could
contain covenants or protective rights that would restrict our operations and potentially impair our competitiveness, such as limitations on our ability to
incur additional debt, limitations on our ability to acquire, sell or license intellectual property rights and other operating restrictions that could adversely
impact our ability to conduct our business. If we need to secure additional financing, such additional fundraising efforts may divert our management and
research efforts from our day-to-day activities, which may adversely affect our ability to develop and commercialize BIO89-100 and any future product
candidates.

To the extent we obtain additional funding through product collaborations, these arrangements would generally require us to relinquish rights to
some of our technologies, product candidates or products, and we may not be able to enter into such agreements, on acceptable terms, if at all. If we are
unable to obtain additional funding on a timely basis, we may be required to curtail or terminate some or all of our development programs or product
candidates.

We will need to raise additional funds to operate our business, but additional funds may not be available on acceptable terms, or at all. Any inability to
raise required capital when needed could harm our liquidity, financial condition, business, operating results and prospects.

As of December 31, 2019, we had no revenue, an accumulated deficit of $73.6 million and cash and cash equivalents of $93.3 million. Based on

our current operating plan, we believe that our cash and cash equivalents, together with the net proceeds from our IPO will be sufficient to meet our
anticipated cash requirements into the second half of 2021. However, to date, we have not generated revenues from our activities and have incurred
substantial operating losses. We expect that we will continue to generate substantial operating losses for the foreseeable future until we complete
development of BIO89-100 or our other product candidates and seek regulatory approvals to market such product candidates. We plan to continue to fund
our operations primarily through utilization of our current financial resources and additional raises of capital. We may raise funds from our current
investors as well as potential outside investors. We expect to finance future cash needs through public or private equity or debt offerings or product
collaborations. However, there is no assurance that such funding will be available to us or that it will be obtained on terms favorable to us or will provide us
with sufficient funds to meet our objectives. Any failure to raise capital as and when needed could have a negative impact on our financial condition and on
our ability to pursue our business plans and strategies.

Our business depends on the success of BIO89-100, our only product candidate under clinical development, which is in the early stages of clinical
development and has not completed a pivotal trial. If we are unable to obtain regulatory approval for and successfully commercialize BIO89-100 or
other future product candidates, or we experience significant delays in doing so, our business will be materially harmed.

To date, the primary focus of our product development has been BIO89-100 for the treatment of patients with NASH. Currently, BIO89-100 is our

only product candidate under clinical development. This may make an investment in our company riskier than similar companies that have multiple
product candidates in active development and that therefore may be able to better sustain a failure of a lead candidate. Successful continued development
and ultimate regulatory approval of BIO89-100 for the treatment of NASH or other indications, including SHTG, is critical to the future success of our
business. We have invested, and will continue to invest, a significant portion of our time and financial resources in the clinical development of BIO89-100.
If we cannot successfully develop, obtain regulatory approval for and commercialize BIO89-100, we may not be able to continue our operations. The
future regulatory and commercial success of BIO89-100 is subject to a number of risks, including the following:

•

•

we may not have sufficient financial and other resources to complete the necessary clinical trials for BIO89-100, including, but not limited
to, the clinical trials needed to obtain drug approval;

the mechanism of action of BIO89-100 is complex, and we do not know the degree to which it will translate into a therapeutic benefit, if
any, in NASH or any other indication, and we do not know the degree to which the complex mechanism of action may contribute to long-
term safety issues or adverse events, if any, when BIO89-100 is taken for prolonged periods such as in the treatment of NASH or any other
indication;

55

 
 
 
 
 
•

•

•

•

•

•

•

•

•

•

we may not be able to obtain adequate evidence from clinical trials of efficacy and safety for BIO89-100 for the treatment of NASH or
other indications;

in our clinical trials for BIO89-100, we may need to adjust our clinical trial procedures and may need additional clinical trial sites, which
could delay our clinical trial progress;

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

patients in our clinical trials may suffer serious adverse effects for reasons that may or may not be related to BIO89-100, which could delay
or prevent further clinical development;

the standards implemented by clinical or regulatory agencies may change at any time and we cannot be certain what efficacy endpoints the
FDA or foreign clinical or regulatory agencies may require in pivotal clinical trials with respect to NASH or any other indication for the
approval of BIO89-100;

the results of later stage clinical trials may not be as favorable as the results we have observed to date in our preclinical studies and Phase
1a clinical trial;

if we obtain accelerated approval of BIO89-100 or any other product candidate based on a surrogate endpoint, we may be required to
conduct a post-approval clinical outcomes trial to confirm the clinical benefit of the product candidate; if any such post-approval trial is not
successful we may not be able to continue marketing the product;

we cannot be certain of the number and type of clinical trials and non-clinical studies that the FDA or other regulatory agencies will require
in order to approve BIO89-100 for the treatment of NASH or any other indication, including SHTG;

if approved for NASH or SHTG, BIO89-100 will likely compete with products that may reach approval for the treatment of NASH prior to
BIO89-100, products that are currently approved for the treatment of SHTG and the off-label use of currently marketed products for NASH
and SHTG; and

we may not be able to obtain, maintain or enforce our patents and other intellectual property rights.

Of the large number of drugs in development in the pharmaceutical industry, only a small percentage results in the submission of a new drug
application or a new BLA to the FDA and even fewer are approved for commercialization. Furthermore, even if we do receive regulatory approval to
market BIO89-100, any such approval may be subject to limitations on the indicated uses or patient populations for which we may market the products.
Accordingly, even if we are able to obtain the requisite financing to continue to fund our development programs, we may be unable to successfully develop
or commercialize BIO89-100. If we or any of our future development collaborators are unable to develop, or obtain regulatory approval for, or, if approved,
successfully commercialize BIO89-100, we may not be able to generate sufficient revenue to continue our business.

Clinical drug development involves a lengthy and expensive process with uncertain timelines and uncertain outcomes, and the results of prior
preclinical or clinical trials are not necessarily predictive of our future results. Our clinical trials may fail to adequately demonstrate the safety and
efficacy of BIO89-100 or any future product candidates.

BIO89-100 and any future product candidates will be subject to rigorous and extensive clinical trials and extensive regulatory approval processes
implemented by the FDA and comparable foreign regulatory authorities before obtaining marketing approval from these regulatory authorities. The drug
development and approval process is lengthy and expensive, and approval is never certain. Investigational new drugs, such as BIO89-100, may not prove to
be safe and effective in clinical trials. We have no direct experience as a company in conducting later stage clinical trials required to obtain regulatory
approval. We may be unable to conduct clinical trials at preferred sites, enlist clinical investigators, enroll sufficient numbers of participants or begin or
successfully complete clinical trials in a timely fashion, if at all. In addition, the design of a clinical trial can determine whether its results will support
approval of a product, and flaws in the design of a clinical trial may not become apparent until the clinical trial is well advanced. Because we have limited
experience as a company designing clinical trials, we may be unable to design and execute a clinical trial to support regulatory approval. Even if our
current clinical trial is successful, it will be insufficient to demonstrate that BIO89-100 is safe or effective for registration purposes.

56

 
 
 
 
 
 
 
 
 
 
 
There is a high failure rate for drugs and biologic products proceeding through clinical trials. Failure can occur at any time during the clinical trial

process. The results of preclinical studies and early clinical trials of BIO89-100 or any future product candidate may not be predictive of the results of
later-stage clinical studies or trials and the results of studies or trials in one set of patients or line of treatment may not be predictive of those obtained in
another. In fact, many companies in the pharmaceutical and biotechnology industries have suffered significant setbacks in late stage clinical trials even
after achieving promising results in preclinical studies and earlier stage clinical trials. In addition, data obtained from preclinical and clinical activities is
subject to varying interpretations, which may delay, limit or prevent regulatory approval. It is impossible to predict when or if BIO89-100 or any future
product candidate will prove effective or safe in humans or will receive regulatory approval. Owing in part to the complexity of biological pathways,
BIO89-100 or any future product candidate may not demonstrate in patients the biochemical and pharmacological properties we anticipate based on
laboratory studies or earlier stage clinical trials, and they may interact with human biological systems or other drugs in unforeseen, ineffective or harmful
ways. The number of patients exposed to product candidates and the average exposure time in the clinical development programs may be inadequate to
detect rare adverse events or findings that may only be detected once a product candidate is administered to more patients and for greater periods of time.
To date, our Phase 1a clinical trial has involved a small patient population of healthy volunteers and, because of the small sample size in such trial, the
results of this clinical trial may be subject to substantial variability and may not be indicative of either future interim results or final results in patients with
liver or cardio-metabolic diseases. If we are unable to successfully demonstrate the safety and efficacy of BIO89-100 or other future product candidates
and receive the necessary regulatory approvals, our business will be materially harmed.

If we experience delays in clinical testing, our commercial prospects will be adversely affected, our costs may increase and our business may be
harmed.

Conducting clinical studies for any product candidates for approval in the United States requires filing an IND application and reaching agreement

with the FDA on clinical protocols, finding appropriate clinical sites and clinical investigators, securing approvals for such studies from the institutional
review board at each such site, manufacturing clinical quantities of product candidates and supplying drug product to clinical sites. Currently, we have an
active IND with the FDA in the United States for BIO89-100. Because our IND is with the gastrointestinal division of the FDA, we may file an additional
IND with another division for any future indications, including SHTG. If any such future IND is not approved by the FDA, our clinical development
timeline may be negatively impacted and any future clinical programs may be delayed or terminated.

We cannot guarantee that we will be able to successfully accomplish required regulatory activities or all of the other activities necessary to initiate
and complete clinical trials. As a result, our preclinical studies and clinical trials may be extended, delayed or terminated, and we may be unable to obtain
regulatory approvals or successfully commercialize our products. We do not know whether any other clinical trials will begin as planned, will need to be
restructured or will be completed on schedule, or at all. Our product development costs will increase if we experience delays in clinical testing. Significant
clinical trial delays also could shorten any periods during which we may have the exclusive right to commercialize BIO89-100 and any future product
candidates or allow our competitors to bring products to market before we do, which would impair our ability to successfully commercialize BIO89-100 or
any future product candidates and may harm our business, results of operations and prospects. Events that may result in a delay or unsuccessful completion
of clinical development include:

•

•

•

•

•

delays in reaching agreement on acceptable terms with prospective CROs and clinical trial sites;

ongoing discussions with the FDA or comparable foreign authorities regarding the scope or design of our clinical trials;

deviations from the trial protocol by clinical trial sites and investigators, or failures to conduct the trial in accordance with regulatory
requirements;

the need to repeat clinical trials as a result of inconclusive or negative results or poorly executed testing or changes in required endpoints or
requests for additional information by the FDA or comparable foreign authorities;

unfavorable FDA inspection and review of a clinical trial site or records of any clinical or preclinical investigation;

57

 
 
 
 
 
 
•

•

•

•

•

•

•

•

•

•

•

•

•

the placement of a clinical hold on a clinical trial by the FDA or comparable foreign authorities;

delays in obtaining, or the inability to obtain, required approvals from institutional review boards or other governing entities at clinical sites
selected for participation in our clinical trials;

failure of third parties, such as CROs, to satisfy their contractual duties to us or meet expected deadlines;

delays in the testing, validation, manufacturing and delivery of the product candidates to the clinical sites;

insufficient supply or deficient quality of product candidate materials or other materials necessary to conduct our clinical trials;

for clinical trials in selected patient populations, delays in identification and auditing of central or other laboratories and the transfer and
validation of assays or tests to be used to identify selected patients;

delays in enrolling participants into our clinical trials;

delays in patients completing a trial or returning for post-treatment follow-up;

delays caused by patients dropping out of a trial due to side effects, disease progression or otherwise;

serious and unexpected drug-related adverse effects experienced by participants in our clinical trials;

implementation of new, or changes to, guidance or interpretations from the FDA or comparable foreign authorities with respect to approval
pathways for any product candidates we are pursuing, such as the draft guidance documents from the FDA and the European Medicines
Agency for the development of NASH that were issued in 2018 and 2019;

withdrawal of clinical trial sites from our clinical trials as a result of changing standards of care or the ineligibility of a site to participate in
our clinical trials; or

changes in government regulations or administrative actions or lack of adequate funding to continue the clinical trials.

Our or our future collaborators’ inability to timely complete clinical development could result in additional costs to us as well as impair our ability

to generate product revenue, continue development, commercialize BIO89-100 and any future product candidates, reach sales milestone payments and
receive royalties on product sales. In addition, if we make changes to a product candidate, we may need to conduct additional nonclinical studies or clinical
trials to bridge or demonstrate the comparability of our modified product candidate to earlier versions, which could delay our clinical development plan or
marketing approval for our current product candidate and any future product candidates.

If we encounter difficulties in enrolling patients in our clinical trials, our clinical development activities could be delayed or otherwise adversely
affected.

The timely completion of clinical trials largely depends on patient enrollment. We may encounter delays in enrolling, or be unable to enroll, a

sufficient number of patients to complete any of our clinical trials, and even once enrolled, we may be unable to retain a sufficient number of patients to
complete any of our trials.

Furthermore, as a result of the inherent difficulties in diagnosing NASH, which can currently only be definitively  diagnosed through a liver biopsy,
and the significant competition for recruiting NASH patients in clinical trials, we or our future collaborators may be unable to enroll the patients we need to
complete clinical trials on a timely basis, or at all.

Many factors affect patient enrollment, including:

•

•

•

•

the size and nature of the patient population, which may be limited due to diagnostic requirements;

the number and location of clinical sites;

competition with other companies for clinical sites or patients;

the availability and amount of any patient stipend;

58

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
•

•

•

•

•

•

the eligibility and exclusion criteria for the trial, including any potential requirement for a biopsy;

the design of the clinical trial;

inability to obtain and maintain patient consents;

significant adverse events or other side effects observed, if any;

risk that enrolled participants will drop out before completion; and

competing clinical trials and clinicians’ and patients’ perceptions as to the potential advantages of the drug being studied in relation to other
available therapies (oral versus injectables, like BIO89-100), including any new drugs that may be approved for the indications we are
investigating.

In addition, our competitors, some of whom have significantly greater resources than we do, are conducting clinical trials for the same indications

and seek to enroll patients in their studies that may otherwise be eligible for our clinical studies or trials, which could lead to slow recruitment and delays in
our clinical programs. Further, since the number of qualified clinical investigators is limited, we expect to conduct some of our clinical trials at the same
clinical trial sites that some of our competitors use, which could further reduce the number of patients who are available for our clinical trials in these sites.

Our inability to enroll a sufficient number of patients for our clinical trials would result in significant delays or may require us to abandon one or

more clinical trials altogether. If we are unable to enroll a sufficient number of patients that will complete clinical testing, we will be unable to seek or gain
marketing approval for BIO89-100 and any future product candidates and our business will be harmed. Even if we are able to enroll a sufficient number of
patients in our clinical studies or trials, delays in patient enrollment may result in increased costs or may affect the timing or outcome of our clinical trials,
which could prevent completion of these trials and adversely affect our ability to advance the development of BIO89-100 and any future product
candidates.

An epidemic of the coronavirus disease is ongoing and may result in significant disruptions to our clinical trials or other business operations, which
could have a material adverse effect on our business.

An epidemic of the coronavirus disease is ongoing throughout the world. As the outbreak is still evolving, much of its impact remains unknown.

As of this filing, it is impossible to predict the effect and potential spread of the coronavirus disease globally. The coronavirus disease may cause significant
disruptions to our clinical trials. If the patients involved with our clinical trials become infected with the coronavirus disease, we may have more AEs and
deaths in our clinical trials as a result. We may also face difficulties enrolling patients in our clinical trials if the patient populations that are eligible for our
clinical trials are impacted by the coronavirus disease. Additionally, if our clinical trial patients are unable to travel to our clinical trial sites as a result of
quarantines or other restrictions resulting from the coronavirus disease, we may experience higher drop-out rates or delays in our clinical trials, and some
patients may not be able to comply with clinical trial protocols if quarantines impede patient movement or interrupt healthcare services, which could impact
our ability to determine the efficacy or safety of BIO89-100. Site initiation and patient enrollment may also be delayed due to prioritization of hospital
resources toward the COVID-19 outbreak.

Additionally, travel restrictions have been implemented with respect to certain countries in an effort to contain the coronavirus disease, and several

countries have expanded screenings of travelers. As travel restrictions are increasingly implemented and extended to other countries, we and our CROs
may be unable to visit our clinical trial sites and monitor the data from our clinical trials on timely basis. Our employees may also face travel restrictions,
which would impact our business. Furthermore, some of our manufacturers and suppliers are in Europe and may be impacted by port closures and other
restrictions resulting from the coronavirus outbreak, which may disrupt our supply chain or limit our ability to obtain sufficient materials for our drug
products.

The ultimate impact of the COVID-19 outbreak or a similar health epidemic is highly uncertain and subject to change. We do not yet know the full
extent of potential delays or impacts on our business, our clinical trials, our CROs, healthcare systems or the global economy as a whole. However, any one
or a combination of these events could have an adverse effect on the operation of and results from our clinical trials and on our other business operations,
which could prevent or delay us from obtaining approval for BIO89-100.

59

 
 
 
 
 
 
 
We are initially developing BIO89-100 for the treatment of NASH, an indication for which there are no approved products. This makes it difficult to
predict the timing and costs of the clinical development of BIO89-100 for the treatment of NASH.

Our current research and development efforts are focused on developing BIO89-100 for the treatment of NASH, an indication for which there are

no approved products. The regulatory approval process for novel  product candidates such as BIO89-100 can be more expensive and take longer than for
other, better known or extensively studied product candidates. As other companies are in later stages of clinical trials for their potential NASH therapies,
we expect that the path for regulatory approval for NASH therapies may continue to evolve in the near term as these other companies refine their
regulatory approval strategies and interact with regulatory authorities. Such evolution may impact our future clinical trial designs, including trial size and
endpoints, in ways that we cannot predict today. Our anticipated development costs would likely increase if development of BIO89-100 or any future
product candidate is delayed because we are required by the FDA to perform studies or trials in addition to, or different from, those that we currently
anticipate. Because of the numerous risks and uncertainties associated with pharmaceutical product development, we are unable to predict the timing or
amount of any increase in our anticipated development costs.

BIO89-100 and any future product candidates may cause undesirable side effects or have other properties that could delay or prevent their regulatory
approval or limit the commercial profile of an approved label.

Undesirable side effects caused by BIO89-100 or any future 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 regulatory
authorities. Additional clinical studies may be required to evaluate the safety profile of BIO89-100 or any future product candidates.

While no serious adverse events were reported in our Phase 1a clinical trial of BIO89-100, the following treatment-related adverse events were

reported in at least two subjects in the treatment cohort: injection site reactions and headaches. Further, it is possible that side effects will become apparent
in long-term animal safety studies, such as those that remain ongoing. We have seen evidence of physiological changes in mice that are consistent with the
changes that may accompany a dramatic amount of weight loss relative to growth in non-obese animals. As with any animal safety finding, to the extent
that these side effects are determined to be clinically relevant, they could have a negative impact on our clinical program.

Future results of our trials could reveal a high and unacceptable severity and prevalence of side effects or unexpected characteristics. In such an

event, we could suspend or terminate our trials or the FDA or comparable foreign regulatory authorities could order us to cease clinical trials or deny
approval of BIO89-100 or any future product candidates for any or all targeted indications. Drug-related side effects could affect patient recruitment or the
ability of enrolled subjects to complete the trial or result in potential product liability claims.

Any of these occurrences could materially and adversely affect our business, financial condition, results of operations and prospects.

It may be difficult to discern whether certain events or symptoms observed during our clinical trials or by patients using our approved products are

related to BIO89-100 or any future product candidates or approved products or some other factor. As a result, we and our development programs may be
negatively affected even if such events or symptoms are ultimately determined to be unlikely related to BIO89-100 or any future product candidates or
approved products. We cannot assure you that additional or more severe adverse side effects related to BIO89-100 or any future product candidates will not
be observed in our clinical trials or in the commercial setting. Further, we expect that BIO89-100 will require multiple administrations vis subcutaneous
injection in the course of a clinical trial, and this chronic administration increases the risk that our clinical drug development programs may not uncover all
possible adverse events that may eventually be experienced by patients treated with BIO89-100, such as rare adverse events or chance findings that may
only be detected once product candidates are administered to ore patients or for greater periods of time. If observed, such adverse side effects could delay
or preclude regulatory approval of BIO89-100 or any future product candidates, limit commercial use or result in the withdrawal of previously granted
marketing approvals. If we or others identify undesirable or unacceptable side effects caused by BIO89-100 or any future product candidates or products:

•

•

we may be required to modify, suspend or terminate our clinical trials;

we may be required to modify or include additional dosage and administration instructions, warnings and precautions, contraindications,
boxed warnings, limitations, restrictions or other statements in the product label for our approved products, or issue field alerts to
physicians and pharmacies;

60

 
 
 
•

•

•

•

•

•

we may be required to conduct costly additional clinical trials;

we may be subject to limitations on how we may promote our approved products;

sales of our approved products may decrease significantly;

regulatory authorities may require us to take our approved products off the market;

we may be subject to regulatory investigations, government enforcement actions, litigation or product liability claims; and

our products may become less competitive or our reputation may suffer.

Any of these results could decrease or prevent any sales of our approved product or substantially increase the costs and expenses of

commercializing and marketing our product.

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

The biopharmaceutical industry is intensely competitive and subject to rapid innovation and significant technological advancements. We believe
the key competitive factors that will affect the development and commercial success of BIO89-100 and any future product candidates are efficacy, safety
and tolerability profile, reliability, convenience of dosing, price, the level of generic competition and reimbursement. Our competitors include multinational
pharmaceutical companies, specialized biotechnology companies, universities and other research institutions. A number of biotechnology and
pharmaceutical companies are pursuing the development or marketing of pharmaceuticals that target the same diseases that we are targeting. Smaller or
earlier-stage companies may also prove to be significant competitors, particularly through collaborative arrangements with large, established companies.
Given the high incidence of NASH and SHTG, it is likely that the number of  companies seeking to develop products and therapies for the treatment of
liver and cardio-metabolic diseases, such as NASH and SHTG, will increase.

There are no currently approved therapies for the treatment of NASH. Although there are no approved therapies that specifically target the
signaling pathways that BIO89-100 is designed to affect, there are numerous  currently approved therapies for treating diseases other than NASH and some
of these currently approved therapies may exert effects that could be similar to BIO89-100. Many of these approved drugs are well-established therapies or
products and are widely accepted by physicians, patients and third-party payors. Some of these drugs are branded and subject to patent protection, and
others are available on a generic basis. Insurers and other third-party payors may also encourage the use of generic products or specific branded products.
We expect that if BIO89-100 or any future product candidates are approved, they will be priced at a significant premium over competitive generic products,
including branded generic products. This may make it difficult for us to differentiate our products from currently approved therapies, which may adversely
impact our business strategy. In addition, many companies are developing new therapeutics, and we cannot predict what the standard of care will be as
BIO89-100 or any future product candidates progress through clinical development. In addition, to the extent BIO89-100 or any future product candidates
are approved for cardio-metabolic indications, such as SHTG, the commercial success of our products will also depend on our ability to demonstrate
benefits over the then-prevailing standard of care, including diet, exercise and lifestyle modifications.

Further, if BIO89-100 or any future product candidates are approved for the treatment of SHTG, we will compete with currently approved
therapies and therapies further along in development. Our competitors both in the United States and abroad include large, well-established pharmaceutical
and generic companies with significantly greater name recognition. Our competitors may be able to charge lower prices than we can, which may adversely
affect our market acceptance. Many of these competitors have greater resources than we do, including financial, product development, marketing,
personnel and other resources. Clinical trials for the treatment of SHTG may be relatively costly and time consuming. The requirements for approval by the
FDA and  comparable foreign regulatory authorities may change over time and this may require changes to ongoing or future clinical trial designs that
could impact timelines and cost.

If our competitors market products that are more effective, safer or cheaper than our products or that reach the market sooner than our products, we

may not achieve commercial success. In addition, the biopharmaceutical industry is characterized by rapid technological change. Because our research
approach integrates many technologies, it may be difficult for us to stay abreast of the rapid changes in other technologies. If we fail to stay at the forefront
of technological change, we may be unable to compete effectively.

61

 
 
 
 
 
 
 
Technological advances or products developed by our competitors may render our technologies, products or product candidates obsolete, less

competitive or not economical.

Many of our competitors have substantially greater financial, technical, human and other resources than we do and may be better equipped to

develop, manufacture and market technologically superior products. In addition, many of these competitors have significantly longer operating histories
and greater experience than we have in undertaking nonclinical studies and human clinical trials of new pharmaceutical products and in obtaining
regulatory approvals of human therapeutic products. Many of our competitors have established distribution channels for the commercialization of their
products, whereas we have no such channel or capabilities. In addition, many competitors have greater name recognition and more extensive collaborative
relationships.

As a result, our competitors may obtain regulatory approval of their products more rapidly than we do or may obtain patent protection or other

intellectual property rights that limit our ability to develop or commercialize our product candidate or any future product candidates. Our competitors may
also develop and succeed in obtaining approval for drugs that are more effective, more convenient, more widely used and less costly or have a better safety
profile than our products and these competitors may also be more successful than we are in manufacturing and marketing their products. If we are unable to
compete effectively against these companies, then we may not be able to commercialize our product candidate or any future product candidates or achieve
a competitive position in the market. This would adversely affect our ability to generate revenue. Our competitors also compete with us in recruiting and
retaining qualified scientific, management and commercial personnel, establishing clinical trial sites and enrolling patients for clinical trials, as well as in
acquiring technologies complementary to, or necessary for, our programs. Our inability to compete effectively in any of these aspects of our business could
harm our business, financial condition, results of operations and prospects.

Lack of efficacy, adverse events or undesirable side effects may emerge in clinical trials conducted by third parties developing FGF product candidates,
which could adversely affect our stock price, our ability to attract additional capital and our development program.

Lack of efficacy, adverse events or undesirable side effects may emerge in clinical trials conducted by third parties developing FGF product

candidates like ours. For example, Bristol-Myers Squibb Company and Akero Therapeutics, Inc. are also developing FGF21 product candidates for the
treatment of NASH. We have no control over their clinical trials or development program, and lack of efficacy, adverse events or undesirable side effects
experienced by subjects in their clinical trials could adversely affect our stock price, our ability to attract additional capital and our development of BIO89-
100 or even the viability of BIO89-100 as a product candidate, including by creating a negative perception of FGF therapeutics by healthcare providers or
patients.

Interim, topline 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 publicly disclose preliminary or topline data from our clinical trials, which are 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 or trial. 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. Topline 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, topline data should be viewed with caution until the final data are available. From time to time, we may also disclose interim data
from our clinical trials. In addition, we may report interim analyses of only certain endpoints rather than all endpoints. 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 continues and more patient
data become available.

62

 
In addition, adverse changes between interim data and final data could significantly harm our business and prospects. Additional disclosure of

interim data by us or by our competitors in the future could also result in volatility in the price of our common stock. 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. 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, drug candidate or our business. If the topline 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, BIO89-100 or any future
product candidates may be harmed, which could harm our business, financial condition, results of operations and prospects.

We may encounter difficulties in managing our growth, which could adversely affect our operations.

We are in the early stages of building the full management team and employee base that we anticipate we will need to complete the development
BIO89-100 and other future product candidates. As of December 31, 2019, we had 20 employees, some of whom are based in the United States and some
of whom are based in Israel. As we advance our preclinical and clinical development programs for product candidates, seek regulatory approval in the
United States and elsewhere and increase the number of ongoing product development programs, we anticipate that we will need to increase our product
development, scientific and administrative headcount. We will also need to establish commercial capabilities in order to commercialize any product
candidates that may be approved. Such an evolution may impact our strategic focus and our deployment and allocation of resources. Our management,
personnel and systems may experience difficulty in adjusting to our growth and strategic focus.

Our ability to manage our operations and growth effectively depends upon the continual improvement of our procedures, reporting systems and
operational, financial and management controls. We may not be able to implement administrative and operational improvements in an efficient or timely
manner and may discover deficiencies in existing systems and controls. If we do not meet these challenges, we may be unable to execute our business
strategies and may be forced to expend more resources than anticipated addressing these issues.

We may acquire additional technology and complementary businesses in the future. Acquisitions involve many risks, any of which could

materially harm our business, including the diversion of management’s attention from core business concerns, failure to effectively exploit acquired
technologies, failure to successfully integrate the acquired business or realize expected synergies or the loss of key employees from either our business or
the acquired businesses.

In addition, in order to continue to meet our obligations as a public company and to support our anticipated long-term growth, we will need to

increase our general and administrative capabilities. Our management, personnel and systems may not be adequate to support this future growth.

If we are unable to successfully manage our growth and the increased complexity of our operations, our business, financial position, results of

operations and prospects may be materially and adversely affected.

We must attract and retain highly skilled employees in order to succeed. If we are not able to retain our current senior management team and our
scientific advisors or continue to attract and retain qualified scientific, technical and business personnel, our business will suffer.

We may not be able to attract or retain qualified personnel and consultants due to the intense competition for such individuals among in the
biotechnology and pharmaceutical industries. If we are not able to attract and retain necessary personnel and consultants to accomplish our business
objectives, we may experience constraints that will significantly impede the achievement of our development and commercial objectives, our ability to
raise additional capital and our ability to implement our business strategy.

63

 
Our industry has experienced a high rate of turnover of management personnel in recent years. We are highly dependent on the development,

regulatory, commercialization and business development expertise of the members of our executive team, as well as other key employees and consultants.
If we lose one or more of our executive officers or other key employees or consultants, our ability to implement our business strategy successfully could be
seriously harmed. Any of our executive officers or other key employees or consultants may terminate their employment at any time and replacing such
individuals may be difficult and time-consuming because of the limited number of individuals in our industry with the necessary breadth of skills and
experience. Competition to hire and retain employees and consultants from this limited pool is intense, and we may be unable to hire, train, retain or
motivate such individuals. Additionally, we do not currently maintain “key person” life insurance on the lives of our executives or any of our employees.
This lack of insurance means that we may not receive adequate compensation for the loss of the services of these individuals. If we are unable to continue
to attract and retain high-quality personnel, the rate and success with which we can discover and develop product candidates and our business will be
limited.

We have relied on, and expect to continue to rely on, third-party manufacturers to produce BIO89-100 or any future product candidates. Any failure by
a third-party manufacturer to produce acceptable product candidates for us pursuant to our specifications and regulatory standards may delay or
impair our ability to initiate or complete our clinical trials, obtain and maintain regulatory approvals or commercialize approved products.

The manufacturing of biologic drugs such as BIO89-100 is complex and the process of identifying the qualifying suppliers takes a significant

investment of time and money. We do not own or operate manufacturing facilities for the production of clinical or commercial quantities of our product
candidates, and we lack the resources and the capabilities to do so. As a result, we currently rely, and expect to rely for the foreseeable future, on third-
party manufacturers to supply us with BIO89-100 and any future product candidates.

We currently have a sole source relationship with Northway Biotechpharma (“BTPH”) pursuant to which they supply us with BIO89-100. If there

should be any disruption in our supply arrangement with BTPH, including any adverse events affecting BTPH, it could have a negative effect on the
clinical development of BIO89-100 and other operations while we work to identify and qualify an alternate supply source.

We do not have a long-term supply agreement with any third-party manufacturer. Reliance on third-party manufacturers entails risks to which we

would not be subject if we manufacture product candidates or products ourselves. For example, if we do not maintain our key manufacturing relationships,
we may fail to find replacement manufacturers or develop our own manufacturing capabilities in a timely manner or at all, which could delay or impair our
ability to obtain regulatory approval for our products and substantially increase our costs or deplete profit margins, if any. If we do find replacement
manufacturers, we may not be able to enter into agreements with them on terms and conditions favorable to us, and there could be a substantial delay
before new facilities could be qualified and registered with the FDA and other comparable foreign regulatory authorities.

Even if we are able to establish agreements with third-party manufacturers, reliance on third-party manufacturers entails additional risks, including:

•

•

•

•

the possible failure of the third party to manufacture product candidates according to our schedule, or at all, including if our third-party
contractors give greater priority to the supply of other products over our product candidates or otherwise do not satisfactorily perform
according to the terms of the agreements between us and them;

the possible breach of the manufacturing agreement by the third party because of factors beyond our control (including a failure to
manufacture product candidates in accordance with our product specifications);

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

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

64

 
 
 
 
 
•

•

•

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

the possible termination or nonrenewal of the agreement by the third party at a time that is costly or inconvenient for us; and

reliance on the third party for regulatory compliance, quality assurance and safety and pharmacovigilance reporting.

Certain raw materials necessary for the manufacture of BIO89-100 under our current manufacturing process, such as reagents that are needed for

the glycoPEGylation, are available only from a single supplier. In April 2018, we entered into a Reagent Supply and Technology Transfer Agreement with
Teva under which Teva agreed to supply us several reagents required for the glycoPEGylation process until December 31, 2022 and transfer the know-how
required for our production of these reagents. We expect the manufacture of these reagents will be transferred to a new supplier prior to expiration of the
agreement with Teva. Any complications arising under our agreement with Teva, with the subsequent transfer of know-how to us, or any difficulties
securing a new supplier could considerably delay the manufacture of BIO89-100. Any significant delay in the acquisition or decrease in the availability of
these raw materials from Teva or any new supplier could considerably delay the manufacture of BIO89-100, which could adversely impact the timing of
any planned trials or the regulatory approvals of BIO89-100.

The FDA and other comparable foreign regulatory authorities require manufacturers to register manufacturing facilities. The FDA and other

comparable foreign regulatory authorities also inspect these facilities to confirm compliance with current good manufacturing practices (“cGMP”).
Contract manufacturers may face manufacturing or quality control problems causing drug substance production and shipment delays or a situation where
the contractor may not be able to maintain compliance with the applicable cGMP requirements. We may have little to no control regarding the occurrence
of third-party manufacturer incidents. Any failure to comply with cGMP requirements or other FDA or comparable foreign regulatory requirements could
adversely affect our clinical research activities and our ability to develop BIO89-100 or any future product candidates and market our products following
approval. Our sole source supplier, BTPH, has not yet manufactured a commercial product, and as a result, has not been subject to inspection by the FDA
and other comparable foreign regulatory authorities.

If BIO89-100 or any future product candidates are approved by the FDA or other comparable foreign regulatory authorities for commercial sale,
we may need to manufacture such product candidate in larger quantities. We intend to use third-party manufacturers for commercial quantities of BIO89-
100 to the extent we advance this product candidate and other product candidates. Our manufacturers may not be able to successfully increase the
manufacturing capacity for any of our product candidates in a timely or efficient manner, or at all. If we are unable to successfully increase the
manufacturing capacity for a product candidate, the regulatory approval or commercial launch of that product candidate may be delayed or there may be a
shortage in the supply of the product candidate.

In addition, the operations of our third-party manufacturers may be subject to earthquakes, power shortages, telecommunications failures, failures

or breaches of information technology systems, water shortages, floods, hurricanes, typhoons, fires, extreme weather conditions, medical epidemics, and
other natural or man-made disasters or business interruptions. Damage or extended periods of interruption to our facilities due to fire, natural disaster,
power loss, communications failure, unauthorized entry or other events could cause us to cease or delay development of some or all of our product
candidates. Our ability to obtain clinical supplies of our product candidates could be disrupted if the operations of these suppliers are affected by a man-
made or natural disaster or other business interruption.

Our current and anticipated future dependence upon others for the manufacture of our product candidates may adversely affect our future profit

margins and our ability to develop our product candidates and commercialize any products that receive regulatory approval on a timely basis.

In some cases, the technical skills or technology required to manufacture our product candidates may be unique or proprietary to the original

manufacturer, we may have difficulty transferring such skills or technology to another third party and a feasible alternative many not exist. These factors
would increase our reliance on such manufacturer or require us to obtain a license from such manufacturer in order to have another third party manufacture
our product candidates. If we are required to change manufacturers for any reason, we will be required to verify that the new manufacturer maintains
facilities and procedures that comply with quality standards and with all applicable regulations and guidelines. For example, in the event that we need to
switch our third-party manufacturer of BIO89-100 from BTPH, which is our sole manufacturing source for BIO89-100, we anticipate that the complexity
of the glycoPEGylation manufacturing process may materially impact the amount of time it may take to secure a replacement manufacturer. The delays
associated with the verification of a new manufacturer, if we are able to identify an alternative source, could negatively affect our ability to develop
product candidates in a timely manner or within budget.

65

 
 
 
 
The manufacture of biologic products is complex and we are subject to many manufacturing risks, any of which could substantially increase our costs
and limit supply of our products.

To date, BIO89-100 has been manufactured by a single third-party manufacturer, BTPH, solely for preclinical studies and clinical trials. This

manufacturer may not be able to scale production to the larger quantities required for large clinical trials and to commercialize BIO89-100. The process of
manufacturing BIO89-100 is complex, highly regulated and subject to several risks, including:

•

•

•

the process of manufacturing biologics is susceptible to product loss due to contamination, equipment failure, improper installation or
operation of equipment, vendor or operator error and improper storage conditions. Even minor deviations from normal manufacturing
processes could result in reduced production yields, product defects and other supply disruptions. If microbial, viral or other
contaminations are discovered in our products or in the manufacturing facilities in which our products are made, the manufacturing
facilities may need to be closed for an extended period of time to investigate and eliminate the contamination;

the manufacturing facilities in which our products are made could be adversely affected by equipment failures, labor and raw material
shortages, financial difficulties of our contract manufacturers, natural disasters, power failures, local political unrest and numerous other
factors; and

any adverse developments affecting manufacturing operations for our products may result in shipment delays, inventory shortages, lot
failures, product withdrawals or recalls or other interruptions in the supply of our products. We may also have to record inventory write-
offs and incur other charges and expenses for products that fail to meet specifications, undertake costly remediation efforts or seek costlier
manufacturing alternatives.

The manufacture of biologic products, and in particular, the glycoPEGylation process, is complex and requires significant expertise and capital
investment, including the development of advanced manufacturing techniques and process controls. Manufacturers of biologic products often encounter
difficulties in production, particularly in scaling up and validating initial production and ensuring the avoidance of contamination. These problems include
difficulties with production costs and yields, quality control, including stability of the product, quality assurance testing, operator error and shortages of
qualified personnel, as well as compliance with strictly enforced federal, state and foreign regulations. We cannot assure you that any stability or other
issues relating to the manufacture of BIO89-100 will not occur in the future.

We have limited process development capabilities and have access only to external manufacturing capabilities. We do not have and we do not
currently plan to acquire or develop the facilities or capabilities to manufacture bulk drug substance or filled drug product for use in human clinical trials or
commercialization. Any delay or interruption in the supply of clinical trial materials, including as a result of breach by us or BTPH  of our agreement with
BTPH, or our inability to agree to the terms of supply or related services in any statement of work, could delay the completion of clinical trials, increase the
costs associated with maintaining clinical trial programs and, depending upon the period of delay, require us to commence new clinical trials at additional
expense or terminate clinical trials completely.

We  plan  to  develop  a  new  drug  product  formulation  for  BIO89-100  and  we  may  be  unsuccessful.  Any  changes  in  methods  of  product  candidate
manufacturing or formulation may result in the need to perform new clinical trials, which would require additional costs and cause delay.

We plan to develop a new drug product formulation of BIO89-100 for late stage clinical trials and commercialization. Our current drug product is

stored as a frozen liquid and is therefore not well-suited to larger clinical trials or commercialization. We have engaged a formulation development
company to explore both a new refrigerated liquid formulation and a freeze-dried, or lyophilized formulation. We also plan to begin development of a pen-
type autoinjector for the new drug product formulation. There is no assurance that we will be successful in developing a new drug product formulation or
an autoinjector on a timely basis or at all, which could impede our development and commercialization strategy for BIO89-100. The FDA or other
comparable foreign regulatory authorities could require nonclinical studies or clinical trials to support introduction of any new formulation and
autoinjector, which could delay completion of clinical trials, require the conduct of bridging clinical trials or the repetition of one or more clinical trials,
increase our clinical trial costs, delay approval of BIO89-100 and jeopardize our ability to commence product sales and generate revenue from BIO89-100,
if approved.

66

 
 
 
 
We rely on third parties to conduct our clinical trials and some aspects of our research and preclinical testing, and those third parties may not perform
satisfactorily, including failing to meet deadlines for the completion of such trials, research or testing.

We currently rely on, and expect to continue to rely on, third parties, such as CROs, clinical data management organizations, medical institutions,

consultants and clinical investigators, to conduct our clinical trials and certain aspects of our research and preclinical testing. Any of these third parties may
terminate their engagements with us at any time. If we need to enter into alternative arrangements, it would delay our product development activities and
such alternative arrangements may not be available on terms acceptable to us.

Our reliance on these third parties for research and development activities will reduce our control over these activities, but will not relieve us of our

responsibilities. For example, we will remain responsible for ensuring that each of our clinical trials is conducted in accordance with the general
investigational plan and protocols for the trial. Moreover, the FDA requires us to comply with standards, commonly referred to as current Good Clinical
Practices, for conducting, recording and reporting the results of clinical trials to assure that data and reported results are credible and accurate and that the
rights, integrity and confidentiality of trial participants are protected. We also are required to register ongoing clinical trials and post the results of
completed clinical trials on a government-sponsored database, ClinicalTrials.gov, within certain timeframes. Failure to do so can result in fines, adverse
publicity and civil and criminal sanctions.

Furthermore, these third parties may also have relationships with other entities, some of which may be our competitors. If these third parties do not

successfully carry out their contractual duties, meet expected deadlines or conduct our clinical trials in accordance with regulatory requirements or our
stated protocols, we will not be able to obtain, or may be delayed in obtaining, marketing approvals for BIO89-100 or any future product candidates and
will not be able to, or may be delayed in our efforts to, successfully commercialize our medicines.

We also expect to rely on other third parties to store and distribute drug supplies for our clinical trials. Any performance failure on the part of our

distributors could delay clinical development, marketing approval and/or commercialization of BIO89-100 or any future product candidates, producing
additional losses and depriving us of potential revenue.

In addition, while we have received the majority of the knowledge with regard to our current product candidate from Teva, we may still depend on
Teva to provide information and documentation regarding certain aspects of BIO89-100 or any future product candidates. If Teva delays providing or fails
to provide such information or documentation, we may also be delayed in our efforts to successfully commercialize BIO89-100 or any future product
candidates. We also depend on Teva to support our efforts to transfer the manufacturing process to a contract manufacturer. If Teva is unable to or
otherwise fails to support such transfer, we may incur significant delay and increased costs in commercializing BIO89-100 or any future product
candidates.

We may not be able to obtain and maintain the third-party relationships that are necessary to develop, commercialize and manufacture some or all of
our product candidates.

We expect to depend on collaborators, partners, licensees, clinical investigators, CROs, manufacturers and other third parties to support our

discovery efforts, to formulate product candidates, to conduct clinical trials for some or all of our product candidates, to manufacture clinical and
commercial scale quantities of our drug substance and drug product and to market, sell and distribute any products we successfully develop. Any problems
we experience with any of these third parties could delay the development, commercialization and manufacturing of our product candidates, which could
harm our results of operations.

We cannot guarantee that we will be able to successfully negotiate agreements for, or maintain relationships with, collaborators, partners, licensees,
clinical investigators, CROs, manufacturers and other third parties on favorable terms, if at all. If we are unable to obtain or maintain these agreements, we
may not be able to clinically develop, formulate, manufacture, obtain regulatory approvals for or commercialize BIO89-100 and any future product
candidates, which will in turn adversely affect our business.

67

 
We expect to expend substantial management time and effort to enter into relationships with third parties and, if we successfully enter into such

relationships, to manage these relationships. In addition, substantial amounts will be paid to third parties in these relationships. However, we cannot control
the amount or timing of resources our future contract partners will devote to our research and development programs, product candidates or potential
product candidates, and we cannot guarantee that these parties will fulfill their obligations to us under these arrangements in a timely fashion, if at all. In
addition, while we manage the relationships with third parties, we cannot control all of the operations of and any outsourcing used by such third parties. We
rely on third parties’ knowledge regarding specific local laws and regulatory requirements in foreign jurisdictions, where applicable.

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

Although the development and commercialization of BIO89-100 is currently our primary focus, as part of our longer-term growth strategy, we plan

to evaluate the development and commercialization of other therapies related to NASH and other liver and cardio-metabolic diseases. The success of this
strategy depends primarily upon our ability to identify and validate new therapeutic candidates, and to identify, develop and commercialize new drugs and
biologics. Our research efforts may initially show promise in discovering potential new drugs and biologics, yet fail to yield product candidates for clinical
development for a number of reasons, including:

•

•

•

•

•

we may need to rely on third parties to generate molecules for some of our product candidate programs;

we may encounter product manufacturing difficulties that limit yield or produce undesirable characteristics that increase the cost of
manufacturing our product candidates, cause delays or make our product candidates unmarketable;

product candidates may cause adverse effects in patients or subjects, even after successful initial toxicology studies, which may make the
product candidates unmarketable;

product candidates may not demonstrate a meaningful benefit to patients or subjects; and

our future collaboration partners may change their development profiles or plans for potential product candidates or abandon a therapeutic
area or the development of a partnered product.

If any of these events occur, we may be forced to abandon our development efforts for one or more programs, which could have a material adverse
effect on our business, operating results and prospects and could potentially cause us to cease operations. Future research programs to identify new product
candidates may require substantial technical, financial and human resources. We may focus our efforts and resources on potential programs or product
candidates that ultimately prove to be unsuccessful.

Product candidates may require additional, time-consuming development efforts prior to commercial sale, including preclinical studies, clinical

trials and approval by the FDA and/or comparable foreign regulatory authorities. All product candidates are prone to the risks of failure that are inherent in
pharmaceutical product development, including the possibility that the product candidate will not be shown to be sufficiently safe and effective for
approval by regulatory authorities. In addition, we cannot assure you that any such products that are approved will be manufactured or produced
economically, be successfully commercialized, be widely accepted in the marketplace, or be more effective than other commercially available alternatives.

We may use our limited financial and human resources to pursue a particular research program or product candidate that is ultimately unsuccessful or
less successful than other programs or product candidates that we may have forgone or delayed.

Because we have limited personnel and financial resources, we may forego or delay the development of certain programs or product candidates
that later prove to have greater commercial potential than the programs or product candidates that we do pursue. 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 for product candidates may not yield any commercially viable products. Similarly, our decisions to delay or terminate drug
development programs may also be incorrect and could cause us to miss valuable opportunities. If we fail to accurately evaluate the commercial potential
or target market for a particular product candidate, we may relinquish valuable rights to that product candidate through strategic collaboration, licensing or
other arrangements or we may allocate our limited internal resources to that product candidate when it would have been more advantageous to enter into
such an arrangement. Any such failure could have a material adverse effect on our business, financial condition, results of operations or prospects.

68

 
 
 
 
 
 
As we evolve from a company that is primarily involved in clinical development to a company that is also involved in commercialization, we may
encounter difficulties in expanding our operations successfully.

As we advance our product candidates through clinical trials, we will need to expand our development, regulatory, manufacturing, and marketing

and sales capabilities and may need to further contract with third parties to provide these capabilities, such as collaborators, distributors, marketers and
additional suppliers. We currently have no experience as a company in or infrastructure for sales, marketing and distribution, and our operations are
currently limited to clinical development activities and as our operations expand, we likely will need to manage additional relationships with such third
parties.

If BIO89-100 or any future product candidate is approved, we intend either to establish a sales organization with technical expertise and supporting

distribution capabilities to commercialize BIO89-100 or any future product candidate or to outsource such functions to one or more third parties. Either of
these options would be expensive and time-consuming. Some or all of these costs may be incurred in advance of any approval of BIO89-100 or any future
product candidate. In addition, we may not be able to hire a sales force that is sufficient in size or has adequate expertise in the medical markets that we
intend to target. Any failure or delay in the development of our internal sales, marketing and distribution capabilities would adversely affect the
commercialization of BIO89-100 and other future product candidates.

Maintaining third-party relationships for these purposes will impose significant added responsibilities  on members of our management and other

personnel. We must be able to effectively manage our development efforts, recruit and train sales and marketing personnel, effectively manage our
participation in the clinical trials in which our product candidates are involved and improve our managerial, development, operational and finance systems,
all of which may impose a strain on our administrative and operational infrastructure.

If we enter into arrangements with third parties to perform sales, marketing or distribution services, any product revenues that we receive, or the

profitability of these product revenues to us, are likely to be lower than if we were to market and sell any products that we develop without the involvement
of these third parties. In addition, we may not be successful in entering into arrangements with third parties to sell and market our products or in doing so
on terms that are favorable to us. We likely will have little control over such third parties, and any of them may fail to devote the necessary resources and
attention to sell and market our products effectively. If we do not establish sales and marketing capabilities successfully, either on our own or in
collaboration with third parties, we will not be successful in commercializing our products.

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

Our drug development programs and the potential commercialization of our product candidates will require substantial additional cash to fund

expenses. We may decide to collaborate with other pharmaceutical and biotechnology companies for the development and potential commercialization of
our product candidates.

We face significant competition in seeking appropriate collaborators. Whether we reach a definitive agreement for a collaboration will depend,

among other things, upon our assessment of the collaborator’s resources and expertise, the terms and conditions of the proposed collaboration and the
proposed collaborator’s evaluation of a number of factors. Those factors may include the design or results of clinical trials, the likelihood of approval by
the FDA or comparable foreign regulatory authorities, the potential market for the subject product candidate, the costs and complexities of manufacturing
and delivering such product candidate to patients, the potential of competing products and the existence of uncertainty with respect to our ownership of
technology, which can exist if there is a challenge to such ownership without regard to the merits of the challenge and industry and market conditions
generally. The collaborators may also consider alternative product candidates or technologies for similar indications that may be available to collaborate on
and whether such a collaboration could be more attractive than the one with us for our product candidate.

Collaborations are complex and time-consuming to negotiate and document. In addition, there have been a significant number of business

combinations among large pharmaceutical companies that have resulted in a reduced number of potential future collaborators.

69

 
We may not be able to negotiate collaborations on a timely basis, on acceptable terms, or at all. If we are unable to do so, we may have to curtail
the development of the product candidate for which we are seeking to collaborate, reduce or delay its development program or one or more of our other
development programs, delay its potential commercialization or reduce the scope of any sales or marketing activities or increase our expenditures and
undertake development or commercialization activities at our own expense. If we elect to increase our expenditures to fund development or
commercialization activities on our own, we may need to obtain additional capital, which may not be available to us on acceptable terms, or at all. If we do
not have sufficient funds, we may not be able to further develop our product candidates or bring them to market and generate product revenue.

We may not be successful in our efforts to identify, in-license or acquire, discover, develop or commercialize additional product candidates.

Although a substantial amount of our effort will focus on the development and potential commercialization of BIO89-100, we also may seek to
identify, in-license or acquire, discover, develop and commercialize additional product candidates. We cannot assure you that our effort to in-license or
acquire additional product candidates will be successful. Even if we are successful in in-licensing or acquiring additional product candidates, their requisite
development activities may require substantial resources, and we cannot assure you that these development activities will result in regulatory approvals.

BIO89-100 and any future product candidates may not achieve adequate market acceptance among physicians, patients, healthcare payors and others
in the medical community necessary for commercial success.

Even if our product candidates receive regulatory approval, they may not gain adequate market acceptance among physicians, patients, healthcare
payors and others in the medical community. Given the number of drugs in development for the treatment of NASH, if we are unsuccessful in achieving a
differentiated profile with BIO89-100 based on efficacy, safety and tolerability, dosing and administration, market acceptance will be limited. Efforts to
educate the medical community and third-party payors on the benefits of our product candidates may require significant resources and may not be
successful. Demonstrating the safety and efficacy of our product candidates and obtaining regulatory approvals will not guarantee future revenue. Our
commercial success also depends on coverage and adequate reimbursement of our product candidates by third-party payors, including government payors,
which may be difficult or time-consuming to obtain, may be limited in scope and may not be obtained in all jurisdictions in which we may seek to market
our products. Governments and private insurers closely examine medical products to determine whether they should be covered by reimbursement and, if
so, the level of reimbursement that will apply. We cannot be certain that third-party payors will sufficiently reimburse sales of our products, or otherwise
enable us to sell our products at profitable prices. Similar concerns could also limit the reimbursement amounts that health insurers or government agencies
in other countries are prepared to pay for our products. In many countries or regions where we may market our products, either directly or with
collaborators, the pricing of prescription drugs is controlled by the government or regulatory agencies.

Regulatory agencies in these countries could determine that the pricing for our products should be based on prices of other commercially available

drugs for the same disease, rather than allowing us to market our products at a premium as new drugs. This may be particularly true for drugs that treat
NASH or SHTG, which some healthcare providers and payors may deem to be a “lifestyle” disease that could be ameliorated by changes in diet and
exercise. The degree of market acceptance of any of our approved product candidates will depend on a number of factors, including:

•

•

•

•

•

•

the efficacy, safety and dosing profile of the product candidate as demonstrated in clinical trials;

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

the clinical indications for which the product candidate is approved;

acceptance of the product candidate as a safe and effective treatment by physicians and patients;

the potential and perceived advantages of the product candidate over alternative treatments, including any similar generic treatments;

the cost of treatment in relation to alternative treatments;

70

 
 
 
 
 
 
 
•

•

•

•

•

•

the availability of coverage and adequate reimbursement and pricing by third parties and government authorities, including any
requirements for biopsy-proven NASH prior to being  approved for reimbursement;

patients’ willingness to pay out-of-pocket in the absence of coverage and/or adequate reimbursement from third-party payors;

the relative convenience and ease of administration;

the frequency and severity of adverse events;

the effectiveness of sales and marketing efforts; and

unfavorable publicity relating to the product candidate.

Sales of medical products also depend on the willingness of physicians to prescribe the treatment, which is likely to be based on a determination by

these physicians that the products are safe, therapeutically effective and cost effective. In addition, the inclusion or exclusion of products from treatment
guidelines established by various physician groups and the viewpoints of influential physicians can affect the willingness of other physicians to prescribe
the treatment. We cannot predict whether physicians, physicians’ organizations, hospitals, other healthcare providers, government agencies or private
insurers will determine that our products are safe, therapeutically effective and cost effective as compared with competing treatments. If any product
candidate is approved but does not achieve an adequate level of acceptance by such parties, we may not generate or derive sufficient revenue from that
product candidate and may not become or remain profitable.

Even if we commercialize BIO89-100 or any future product candidate, we may face challenges to achieving profitability such as our products becoming
subject to unfavorable pricing regulations, third-party reimbursement practices or healthcare reform initiatives, which could harm our business.

The regulations that govern marketing approvals, pricing and reimbursement for new drug products vary widely from country to country. Current

and future legislation may significantly change the approval requirements in ways that could involve additional costs and cause delays in obtaining
approvals. Some countries require approval of the sale price of a drug before it can be marketed. In many countries, the pricing review period begins after
marketing or product licensing approval is granted. In some foreign markets, prescription pharmaceutical pricing remains subject to continuing
governmental control even after initial approval is granted. As a result, we might obtain marketing approval for a product in a particular country, but then
be subject to price regulations that delay or limit our commercial launch of the product, possibly for lengthy time periods, which could negatively impact
the revenue we generate from the sale of the product in that particular country. Adverse pricing limitations may hinder our ability to recoup our investment
in one or more product candidates, even if our product candidates obtain marketing approval.

Our ability to commercialize any products successfully also will depend in part on the extent to which coverage and adequate reimbursement for

these products and related treatments will be available from third-party payors, including government health care programs and private health insurers.
Such third-party payors determine which medications they will cover and establish reimbursement levels. Government authorities and other third-party
payors have attempted to control costs by limiting coverage and the amount of reimbursement for particular medications. Increasingly, third-party payors
are requiring that drug companies provide them with predetermined discounts from list prices and are challenging the prices charged for medical products.
We cannot be sure that coverage and reimbursement will be available for any product that we or our future collaborators commercialize and, if
reimbursement is available, what the level of reimbursement will be. Coverage and reimbursement may impact the demand for, or the price of, any product
candidate for which we or our future collaborators obtain marketing approval. If coverage and reimbursement are not available or reimbursement is
available only to limited levels, we and our future collaborators may not be able to successfully commercialize any product candidate for which marketing
approval is obtained.

There may be significant delays in obtaining coverage and reimbursement for newly approved drugs, and coverage may be more limited than the
purposes for which the drug is approved by the FDA or comparable foreign regulatory authorities. Moreover, eligibility for coverage and reimbursement
does not imply that a drug will be paid for in all cases or at a rate that covers our costs, including research, development, manufacture, sale and distribution.
Interim reimbursement levels for new drugs, if applicable, may also not be sufficient to cover our costs and may only be temporary. Reimbursement rates
may vary according to the use of the drug and the clinical setting in which

71

 
 
 
 
 
 
 
it is used, may be based on reimbursement levels already set for lower cost drugs and may be incorporated into existing payments for other services. Net
prices for drugs may be reduced by mandatory discounts or rebates required by government healthcare programs or private payors and by any future
relaxation of laws that presently restrict imports of drugs from countries where they may be sold at lower prices than in the United States. Our inability to
promptly obtain coverage and profitable reimbursement rates from both government-funded and private payors for any approved products that we develop
could have a material adverse effect on our operating results, our ability to raise capital needed to commercialize products and our overall financial
condition.

To become and remain profitable, we or any potential future collaborator must develop and eventually commercialize BIO89-100 or any future

product candidates with significant market potential at an adequate profit margin after cost of goods sold and other expenses. Commercialization of BIO89-
100 or any future product candidates may entail a substantial cost of goods sold and there can be no assurance that we will be able to achieve a suitable
gross margin with respect to sales of BIO89-100 or any future product candidates.

Healthcare reform in the United States may negatively impact our ability to profitably sell our product candidates, if approved, and to recoup the
upfront investment needed to obtain regulatory approval of our product candidates.

Third-party payors, whether domestic or foreign, or governmental or commercial, are continually developing and advancing new methods of

controlling healthcare costs. The United States and many foreign jurisdictions have enacted or proposed legislative and regulatory changes affecting the
healthcare system that could prevent or delay marketing approval of our product candidates, restrict or regulate post-approval activities and affect our
ability to profitably sell any product for which we obtain marketing approval.

In March 2010, the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act of 2010

(collectively, the “Affordable Care Act”) was enacted, which includes measures that have significantly changed the way health care is financed by both
governmental and private insurers. Among the provisions of the Affordable Care Act of particular importance include:

•

•

•

•

•

•

•

•

an annual, nondeductible fee on any entity that manufactures or imports specified branded prescription drugs and biologic agents, which is
apportioned among these entities according to their market share in certain government healthcare programs;

a Medicare Part D coverage gap discount program, in which manufacturers must agree to offer point-of-sale discounts off negotiated prices
of applicable brand drugs to eligible beneficiaries during their coverage gap period, as a condition for the manufacturer’s outpatient drugs
to be covered under Medicare Part D;

an increase in the statutory minimum rebates a manufacturer must pay under the Medicaid Drug Rebate Program to 23.1% and 13.0% of
the average manufacturer price for branded and generic drugs, respectively;

a methodology by which rebates owed by manufacturers under the Medicaid Drug Rebate Program are calculated for drugs that are
inhaled, infused, instilled, implanted or injected;

a licensure framework for follow-on biologic products;

an extension of a manufacturers’ Medicaid rebate liability to covered drugs dispensed to individuals who are enrolled in Medicaid managed
care organizations;

a new Patient-Centered Outcomes Research Institute to oversee, identify priorities in and conduct comparative clinical effectiveness
research, along with funding for such research; and

establishment of a Center for Medicare Innovation at the Centers for Medicare & Medicaid Services (“CMS”) to test innovative payment
and service delivery models to lower Medicare and Medicaid spending, potentially including prescription drug spending.

72

 
 
 
 
 
 
 
 
 
There remain judicial, executive, and congressional challenges to certain aspects of the Affordable Care Act which could potentially void or

significantly modify the Affordable Care Act in part or in whole. For example, since January 2017, President Trump signed Executive Orders and other
directives designed to delay, circumvent, or loosen certain requirements mandated by the Affordable Care Act. On December 22, 2017, President Trump
signed into law the Tax Act, which includes a provision repealing the individual mandate to maintain health insurance coverage under the Affordable Care
Act effective January 1, 2019. Additionally, the 2020 federal spending package permanently eliminated, effective January 1, 2020, the Affordable Care
Act’s mandated “Cadillac” tax on high-cost employer-sponsored health coverage and medical device tax and, effective January 1, 2021, also eliminates the
health insurer tax. On December 14, 2018, a U.S. District Court Judge in the Northern District of Texas ruled that the individual mandate is a critical and
inseverable feature of the Affordable Care Act, and because it was repealed as part of the Tax Act, the remaining provisions of the Affordable Care Act are
invalid as well. The decision was been appealed to the United States Court of Appeals for the Fifth Circuit and on December 18, 2019, the United States
Court of Appeals for the Fifth Circuit upheld the District Court’s ruling that the individual mandate was unconstitutional, but remanded the case back to the
District Court to determine whether the remaining provisions of the Affordable Care Act were nonetheless valid. On March 2, 2020, the United States
Supreme Court granted the petitions for writs of certiorari to review this case, and has allotted one hour for oral arguments, which are expected to occur in
the fall. It is unclear how such litigation and other efforts will impact the Affordable Care Act.

At the same time, there has been increasing legislative and enforcement interest in the United States with respect to specialty drug pricing
practices. Specifically, there have been several recent U.S. congressional inquiries and proposed bills designed to, among other things, bring more
transparency to drug pricing, reduce the cost of prescription drugs under Medicare, review the relationship between pricing and manufacturer patient
programs and reform government program reimbursement methodologies for drugs. At the federal level, the Trump administration’s budget proposal for
the government’s fiscal year 2021 includes a $135 billion allowance to support legislative proposals seeking to reduce drug prices, increase competition,
lower out-of-pocket drug costs for patients, and increase patient access to lower-cost generic and biosimilar drugs. The Trump administration previously
released a “Blueprint,” or plan, to lower drug prices and reduce out of pocket costs of drugs that contained  proposals to increase drug manufacturer
competition, increase the negotiating power of certain federal healthcare programs, incentivize manufacturers to lower the list price of their products, and
reduce the out of pocket costs of drug products paid by consumers. We expect that the healthcare reform measures that have been adopted and may be
adopted in the future may result in more rigorous coverage criteria and in additional downward pressure on the price that we receive for any approved
product and could seriously harm our future revenues. Any reduction in reimbursement from Medicare or other government programs may result in a
similar reduction in payments from private payors. The implementation of cost containment measures or other healthcare reforms may prevent us from
being able to generate product revenue, attain profitability or commercialize our products.

There have been, and likely will continue to be, legislative and regulatory proposals at the foreign, federal and state levels directed at broadening

the availability of healthcare and containing or lowering the cost of healthcare. The implementation of cost containment measures or other healthcare
reforms may prevent us from being able to generate product revenue, attain profitability, or commercialize our products. Such reforms could have an
adverse effect on anticipated revenue from product candidates that we may successfully develop and for which we may obtain regulatory approval and may
affect our overall financial condition, including our ability to recoup the upfront investment needed to obtain regulatory approval for our product
candidates.

Our international operations may expose us to business, regulatory, political, operational, financial, pricing and reimbursement risks associated with
doing business outside of the United States.

Our use of our international facilities subject us to U.S. and foreign governmental trade, import and export, and customs regulations and laws.

Compliance with these regulations and laws is costly and exposes us to penalties for non-compliance. Furthermore, if we succeed in developing any
products, we intend to market them in other jurisdictions in addition to the United States. If approved, we may hire sales representatives and conduct
physician and patient association outreach activities outside of the United States.

Doing business internationally potentially involves a number of risks, including but not limited to:

•

•

•

multiple, conflicting and changing laws and regulations such as privacy regulations, tax laws, export and import restrictions, employment
laws, regulatory requirements, and other governmental approvals, permits and licenses;

failure by us to obtain and maintain regulatory approvals for the use of our products in various countries;

rejection or qualification of foreign clinical trial data by the competent authorities of other countries;

73

 
 
 
 
•

•

•

•

•

•

•

•

•

•

•

•

additional potentially relevant third-party patent rights;

complexities and difficulties in obtaining, maintaining, protecting and enforcing our intellectual property;

difficulties in staffing and managing foreign operations;

a shortage of high-quality employees;

laws and business practices favoring local companies;

complexities associated with managing multiple payor reimbursement regimes, government payors or patient self-pay systems;

limits in our ability to penetrate international markets;

financial risks, such as longer payment cycles, difficulty collecting accounts receivable, the impact of local and regional financial crises on
demand and payment for our products and exposure to foreign currency exchange rate fluctuations;

natural disasters, political and economic instability, including wars, terrorism and political unrest, actual or potential public health
emergencies, including the recent coronavirus (COVID-19) disease outbreak, boycotts, curtailment of trade and other business restrictions;

the imposition of restrictions on the activities of foreign agents and representatives;

certain expenses including, among others, expenses for travel, translation and insurance; and

regulatory and compliance risks that relate to anti-corruption compliance and record-keeping that may fall within the purview of the U.S.
Foreign Corrupt Practices Act, its accounting provisions or its anti-bribery provisions or provisions of anti-corruption or anti-bribery laws
in other countries.

Any of these factors could harm our ongoing international clinical operations and supply chain, as well as any future international expansion and

operations and, consequently, our business, financial condition, prospects and results of operations.

If we fail to comply with foreign regulatory requirements governing human clinical trials and marketing approval for drugs, we could be prevented
from selling our product candidates in foreign markets, which may adversely affect our operating results and financial condition.

The requirements governing the conduct of clinical trials, product licensing, pricing, and reimbursement for marketing our product candidates

outside the United States vary greatly from country to country and may require additional testing. We expect that our future clinical development of our
product candidates will involve a number of clinical trials in foreign jurisdictions. We have no direct experience as a company in obtaining foreign
regulatory approvals. The time required to obtain approvals outside the United States may differ from that required to obtain FDA approval. We may not
obtain foreign regulatory approvals on a timely basis, if at all. Approval by the FDA does not guarantee approval by comparable foreign regulatory
authorities, and approval by one foreign regulatory authority does not ensure approval by regulatory authorities in other countries or by the FDA. Failure to
comply with these regulatory requirements or obtain required approvals could impair our ability to develop foreign markets for our product candidates and
may have a material adverse effect on our results of operations and financial condition.

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

We face an inherent risk of product liability exposure related to the testing of our product candidates in human clinical trials and will face an even

greater risk if we commercialize any resulting products. Product liability claims may be brought against us by subjects enrolled in our clinical trials,
patients, or others using our products. If we cannot successfully defend ourselves against claims that our product candidates or products that we may
develop caused injuries, we could incur substantial liabilities. Regardless of merit or eventual outcome, liability claims may result in:

•

•

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

product recalls or a change in the indications for which products may be used;

74

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
•

•

•

•

•

•

•

•

termination of clinical trial sites or entire trial programs;

injury to our reputation and significant negative media attention;

withdrawal of clinical trial participants;

significant costs to defend the related litigation;

substantial monetary awards to trial subjects or patients;

loss of revenue;

diversion of management and scientific resources from our business operations; and

the inability to commercialize any products that we may develop.

Our clinical trial liability insurance coverage may not adequately cover all liabilities that we may incur. We may not be able to maintain insurance

coverage at a reasonable cost or in an amount adequate to satisfy any liability that may arise. Our inability to obtain product liability insurance at an
acceptable cost or to otherwise protect against potential product liability claims could prevent or delay the commercialization of any products or product
candidates that we develop. We intend to expand our insurance coverage for products to include the sale of commercial products if we obtain marketing
approval for our product candidates in development, but we may be unable to obtain commercially reasonable product liability insurance for any products
approved for marketing. Large judgments have been awarded in class action lawsuits based on drugs that had unanticipated side effects. If we are sued for
any injury caused by our products, product candidates or processes, our liability could exceed our product liability insurance coverage and our total assets.
Claims against us, regardless of their merit or potential outcome, may also generate negative publicity or hurt our ability to obtain physician endorsement
of our products or expand our business.

Our employees, contractors, vendors, principal investigators, consultants and future partners may engage in misconduct or other improper activities,
including noncompliance with regulatory standards and requirements and insider trading.

We are exposed to the risk of fraud or other misconduct by our employees, contractors, vendors, principal investigators, consultants or future

partners. Misconduct by these parties could include failures to comply with FDA regulations, to provide accurate information to the FDA, to comply with
federal and state healthcare fraud and abuse laws and regulations, to report financial information or data timely, completely or accurately, or to 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, misconduct, 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. Third-
party 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. Although we have adopted a Code of Business Conduct and Ethics, it is not always possible to identify and deter
misconduct, and the precautions we take to detect and prevent this activity may not be effective in controlling unknown or unmanaged risks or losses or in
protecting us from governmental investigations or other actions or lawsuits stemming from a failure to comply with these laws or regulations. If any such
actions are instituted against us resulting from this misconduct and we are not successful in defending ourselves or asserting our rights, those actions could
have a significant impact on our business, including the imposition of significant fines or other sanctions. If we or our future partners market products in a
manner that violates fraud and abuse and other healthcare laws, or if we or our future partners violate government price reporting laws, we or our future
partners may be subject to administrative civil and/or criminal penalties, among other sanctions.

Most states also have statutes or regulations similar to these federal laws, which may apply to items such as pharmaceutical products and services
reimbursed by private insurers. We and/or our future partners may be subject to administrative, civil and criminal sanctions for violations of any of these
federal and state laws.

75

 
 
 
 
 
 
 
 
 
Pharmaceutical and other healthcare companies have been prosecuted under these laws for a variety of promotional and marketing activities, such

as: providing free trips, free goods, sham consulting fees and grants and other monetary benefits to prescribers; reporting to pricing services inflated
average wholesale prices that were then used by federal programs to set reimbursement rates; engaging in off-label promotion; and submitting inflated best
price information to the Medicaid Rebate Program to reduce liability for Medicaid rebates. Ensuring that our internal operations and future business
arrangements with third parties comply with applicable healthcare laws and regulations will involve substantial costs. It is possible that governmental
authorities will conclude that our business practices do not comply with current or future statutes, regulations, agency guidance or case law involving
applicable fraud and abuse or other healthcare laws and regulations.

Our business operations and relationships with investigators, healthcare professionals, consultants, third-party payors, patient organizations and
customers are subject to broadly applicable healthcare regulatory laws, which could expose us to penalties.

Healthcare providers, physicians and third-party payors will play a primary role in the recommendation and prescription of any product candidate

for which we obtain regulatory approval. Our current and future arrangements may expose us to broadly applicable fraud and abuse and other healthcare
laws that may constrain the business or financial arrangements and relationships through which we would research, market, sell and distribute our products.
Even though we will not control referrals of healthcare services or bill directly to Medicare, Medicaid or other third-party payors, federal and state
healthcare laws pertaining to fraud and abuse are and will be applicable to our business. Such laws include, but are not limited to, the following:

•

•

•

•

Federal false claims laws, including the federal civil False Claims Act (“FCA”), which can be enforced through civil whistleblower or qui
tam actions, and false statements and civil monetary penalties law prohibit, among others, any person from knowingly presenting, or
causing to be presented, a false claim for payment to the federal government or knowingly making, or causing to be made, a false statement
to get a false claim paid.

The federal Anti-Kickback Statute prohibits, among other things, knowingly and willfully offering, paying, soliciting or receiving
remuneration to induce, or in return for, purchasing, leasing, ordering or arranging for the purchase, lease or order of any healthcare item or
service reimbursable under Medicare, Medicaid or other federally financed healthcare programs. This statute has been interpreted to apply
to arrangements between pharmaceutical manufacturers, on the one hand, and prescribers, purchasers and formulary managers, on the
other. Although there are several statutory exceptions and regulatory safe harbors protecting certain common activities from prosecution,
the exceptions and safe harbors are drawn narrowly, and practices that involve remuneration intended to induce prescribing, purchasing or
recommending may be subject to scrutiny if they do not qualify for an exception or safe harbor. In addition, the intent standard under the
federal Anti-Kickback Statute was amended by the Affordable Care Act to a stricter standard such that a person or entity no longer needs to
have actual knowledge of the statute or specific intent to violate it in order to have committed a violation. Moreover, 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 FCA.

The federal Health Insurance Portability and Accountability Act of 1996 (“HIPAA”), which prohibits, among other things, knowingly and
willfully executing, or attempting to execute, a scheme or artifice to defraud any healthcare benefit program or obtain, by means of false or
fraudulent pretenses, representations, or promises, any of the money or property owned by, or under the custody or control of, any
healthcare benefit program, regardless of the payor (e.g., public or private), willfully obstructing a criminal investigation of a healthcare
offense, and knowingly and willfully falsifying, concealing or covering up by any trick or device a material fact or making any materially
false, fictitious or fraudulent statements in connection with the delivery of, or payment for, healthcare benefits, items or services relating to
healthcare matters. Similar to the federal Anti-Kickback Statute, a person or entity does not need to have actual knowledge of the statute or
specific intent to violate it in order to have committed a violation.

Patient data privacy and security regulation, including, in the United States, HIPAA, as amended by the Health Information Technology for
Clinical Health Act of 2009 (“HITECH”), and their respective implementing regulations, which impose specified requirements on
“covered entities,” including healthcare providers, health plans, and healthcare clearinghouses, as well as their respective “business
associates” that perform services for them that involve the use, or disclosure of, individually identifiable health information relating to the
privacy, security and transmission of individually identifiable health information.

76

The federal transparency requirements under the Physician Payments Sunshine Act, enacted as part of the Affordable Care Act, that require
applicable manufacturers of covered drugs, devices, biologics and medical supplies for which payment is available under Medicare,
Medicaid or the Children’s Health Insurance Program, with specific exceptions, to track and annually report to CMS payments and other
transfers of value provided to physicians, as defined by such law, and teaching hospitals and certain ownership and investment interests
held by physicians or their immediate family members in the applicable manufacturer, and disclosure of such information will be made by
CMS on a publicly available website.

Analogous state, local or foreign laws, such as state anti-kickback and false claims laws, which may apply to items or services reimbursed
by any third-party payor, including commercial insurers; state and local marketing and/or transparency laws applicable to manufacturers
that may be broader in scope than the federal requirements; state laws that require biopharmaceutical companies to comply with the
biopharmaceutical industry’s voluntary compliance guidelines and the relevant compliance guidance promulgated by the federal
government; state and local laws that require licensure or registration by sales and marketing agents of a pharmaceutical company; state
laws that require disclosure of information related to drug pricing; and state and foreign 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 as
HIPAA.

Pharmaceutical and other healthcare companies have been prosecuted under these laws for a variety of promotional and marketing activities, such

as: providing free trips, free goods, sham consulting fees and grants and other monetary benefits to prescribers; reporting to pricing services inflated
average wholesale prices that were then used by federal programs to set reimbursement rates; engaging in off-label promotion; and submitting inflated best
price information to the Medicaid Rebate Program to reduce liability for Medicaid rebates. Ensuring that our internal operations and future business
arrangements with third parties comply with applicable healthcare laws and regulations will involve substantial costs. It is possible that governmental
authorities will conclude that our business practices do not comply with current or future statutes, regulations, agency guidance or case law involving
applicable fraud and abuse or other healthcare laws and regulations.

The global data protection landscape is rapidly evolving, and we may be affected by or subject to new, amended or existing laws and regulations in

the future, including as our operations continue to expand or if we operate in foreign jurisdictions. For example, in June 2018, California enacted the
California Consumer Privacy Act of 2018 (the “CCPA”), which took effect on January 1, 2020. The CCPA gives California residents the right to access and
require deletion of their personal information, the right to opt out of certain personal information sharing, and the right to detailed information about how
their personal information is collected, used and shared. The CCPA provides civil penalties for violations, as well as a private right of action for data
breaches that is expected to increase data breach litigation. Although the CCPA includes exemptions for certain clinical trials data, the law may increase
our compliance costs and potential liability with respect to other personal information we collect about California residents. The CCPA has prompted a
wave of proposals for new federal and state privacy legislation that, if passed, could increase our potential liability, increase our compliance costs and
adversely affect our business. Several foreign jurisdictions, including the European Union (EU), its member states, the United Kingdom, Japan and
Australia, among others, have adopted legislation and regulations that increase or change the requirements governing the collection, use, disclosure and
transfer of the personal information of individuals in these jurisdictions. Additionally, certain countries have passed or are considering passing laws that
require local data residency and/or restrict the international transfer of data. These laws have the potential to increase costs of compliance, risks of
noncompliance and penalties for noncompliance.

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

significant civil, criminal and administrative penalties, damages, disgorgement, fines, imprisonment, exclusion from government funded healthcare
programs, such as Medicare and Medicaid, additional oversight and reporting obligations, contractual damages, reputational harm, diminished profits and
future earnings, and the curtailment or restructuring of our operations. If any of the physicians or other healthcare providers or entities with whom we
expect to do business is found not to be in compliance with applicable laws, that person or entity may be subject to significant criminal, civil or
administrative sanctions, including exclusions from government funded healthcare programs.

77

 
 
 
We depend on our information technology systems and those of our third-party collaborators, service providers, contractors or consultants. Our
internal computer systems, or those of our third-party collaborators, service providers, contractors or consultants, may fail or suffer security breaches,
disruptions, or incidents, which could result in a material disruption of our development programs or loss of data or compromise the privacy, security,
integrity or confidentiality of sensitive information related to our business and have a material adverse effect on our reputation, business, financial
condition or results of operations.

In the ordinary course of our business, we collect, store and transmit large amounts of confidential information, including intellectual property,
proprietary business information and personal information. Our internal technology systems and infrastructure, and those of our current or future third-
party collaborators, service providers, contractors and consultants are vulnerable to damage from computer viruses, unauthorized access or use resulting
from malware, natural disasters, terrorism, war and telecommunication and electrical failures, denial-of-service attacks, cyber-attacks or cyber-intrusions
over the Internet, hacking, phishing and other social engineering attacks, persons inside our organizations (including employees or contractors), loss or
theft, or persons with access to systems inside our organization. Attacks on information technology systems are increasing in their frequency, levels of
persistence, sophistication and intensity, and they are being conducted by increasingly sophisticated and organized foreign governments, groups and
individuals with a wide range of motives and expertise. In addition to extracting or accessing sensitive information, such attacks could include the
deployment of harmful malware, ransomware, denial-of-service attacks, social engineering and other means to affect service reliability and threaten the
security, confidentiality, integrity and availability of information. The prevalent use of mobile devices that access sensitive information also increases the
risk of data security incidents which could lead to the loss of confidential information or other intellectual property. While to our knowledge we have not
experienced any material system failure, accident or security breach to date, if such an event were to occur and cause interruptions in our operations or the
operations of third-party collaborators, service providers, contractors and consultants, it could result in a material disruption of our development programs
and significant reputational, financial, legal, regulatory, business or operational harm. The costs to us to mitigate, investigate and respond to potential
security incidents, breaches, disruptions, network security problems, bugs, viruses, worms, malicious software programs and security vulnerabilities could
be significant, and while we have implemented security measures to protect our data security and information technology systems, our efforts to address
these problems may not be successful, and these problems could result in unexpected interruptions, delays, cessation of service and other harm to our
business and our competitive position.

For example, the loss of clinical trial data from completed, ongoing or planned clinical trials for our product candidates 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 real or perceived security breach
affects our systems (or those of our third-party collaborators, service providers, contractors or consultants), or results in the loss of or accidental, unlawful
or unauthorized access to, use of, release of, or other processing of personally identifiable information or damage to our data or applications or other data
or applications relating to our technology or product candidates, or inappropriate disclosure of confidential or proprietary information, we could incur
liabilities and the further development of our product candidates could be delayed. Such a breach may require notification to governmental agencies, the
media or individuals pursuant to various foreign, domestic (federal and state) privacy and security laws, if applicable, including HIPAA, as amended by
HITECH, and its implementing rules and regulations, as well as regulations promulgated by the Federal Trade Commission and state breach notification
laws. In addition, our liability insurance may not be sufficient in type or amount to cover us against claims related to security breaches, cyberattacks and
other related incidents.

Any failure or perceived failure by us or any third-party collaborators, service providers, contractors or consultants to comply with our privacy,

confidentiality, data security or similar obligations, or any data security incidents or other security breaches that result in the accidental, unlawful or
unauthorized access to, use of, release of, processing of, or transfer of sensitive information, including personally identifiable information, may result in
negative publicity, harm to our reputation, governmental investigations, enforcement actions, regulatory fines, litigation or public statements against us,
could cause third parties to lose trust in us or could result in claims by third parties, including those that assert that we have breached our privacy,
confidentiality, data security or similar obligations, any of which could have a material adverse effect on our reputation, business, financial condition or
results of operations. To the extent we maintain individually identifiable health information, we could be subject to fines and penalties (including civil and
criminal) under HIPAA for any failure by us or our business associates to comply with HIPAA’s requirements. Moreover, data security incidents and other
security breaches can be difficult to detect, and any delay in identifying them may lead to increased harm. While we have implemented data security
measures intended to protect our information, data, information technology systems, applications and infrastructure, there can be no assurance that such
measures will successfully prevent service interruptions or data security incidents.

European data collection is governed by restrictive regulations governing the collection, use, processing and cross-border transfer of personal
information.

We may collect, process, use or transfer personal information from individuals located in the European Economic Area in connection with our

business, including in connection with conducting clinical trials in the European Economic Area (the “EEA”). Additionally, if any of our product
candidates are approved, we may seek to commercialize those products in the European Economic Area. The collection and use of personal health data in
the European Economic Area is governed by the provisions of the General Data Protection Regulation ((EU) 2016/679) (the “GDPR”), along with other
European Union and country-specific laws and regulations. The United Kingdom and Switzerland have also adopted data protection laws and regulations.
These legislative acts (together with regulations and guidelines) impose requirements relating to having legal bases for processing personal data relating to
identifiable individuals and transferring such data outside of the European Economic Area, including to the United States, providing details to those
individuals regarding the processing of their personal data, keeping personal data secure, having data processing agreements with third parties who process
personal data, responding to individuals’ requests to exercise their rights in respect of their personal data, reporting security breaches involving personal
data to the competent national data protection authority and affected individuals, appointing data protection officers or corporate representatives,
conducting data protection impact assessments and record-keeping. The GDPR imposes additional responsibilities and liabilities in relation to personal
data that we process and we may be required to put in place additional mechanisms ensuring compliance with the new data protection rules. Failure to
comply with the requirements of the GDPR and related national data protection laws of the member states of the European Economic Area and other states
in the European Economic Area may result in substantial fines, other administrative penalties and civil claims being brought against us, which could have a
material adverse effect on our business, financial condition and results of operations. European data protection authorities may interpret the GDPR and
national laws differently and may impose additional requirements, which adds to the complexity of processing personal data in or from the EEA or United
Kingdom. Guidance on implementation and compliance practices are often updated or otherwise revised.

Our insurance policies are expensive and only protect us from some business risks, leaving us exposed to significant uninsured liabilities.

We do not carry insurance for all categories of risk that our business may encounter. We believe that we maintain insurance customary for

businesses of our size and type, including clinical trial liability insurance.

However, there are types of losses we may incur that cannot be insured against or that we believe are not economically reasonable to insure.

Moreover, any loss incurred could exceed policy limits and policy payments made to us may not be made on a timely basis. Such losses could adversely
affect our business prospects, results of operations, cash flows and financial condition. We do not know if our current levels of coverage are adequate or if
we will be able to obtain insurance with adequate levels of coverage in the future, if at all. Any significant uninsured liability may require us to pay
substantial amounts, which could materially and adversely affect our financial position and results of operations.

Disputes under key agreements or conflicts of interest with our scientific advisors or clinical investigators could delay or prevent development or
commercialization of our product candidates.

Any agreements we have or may enter into with third parties, such as collaboration, license, formulation supplier, manufacturing, clinical research

organization or clinical trial agreements, may give rise to disputes regarding the rights and obligations of the parties. Disagreements could develop over
contract interpretation, rights to ownership or use of intellectual property, the scope and direction of research and development, the approach for regulatory
approvals or commercialization strategy. We intend to conduct research programs in a range of therapeutic areas, but our pursuit of these opportunities
could result in conflicts with the other parties to these agreements that may be developing or selling pharmaceuticals or conducting other activities in these
same therapeutic areas. Any disputes or commercial conflicts could lead to the termination of our agreements, delay progress of our product development
programs, compromise our ability to renew agreements or obtain future agreements, lead to the loss of intellectual property rights, result in increased
financial obligations for us or result in costly litigation.

79

 
We work with outside scientific advisors and collaborators at academic and other institutions that assist us in our research and development efforts.
Our scientific advisors are not our employees and may have other commitments that limit their availability to us. If a conflict of interest between their work
for us and their work for another entity arises, we may lose their services.

If the market opportunities for any product that we or our strategic collaborators develop are smaller than we believe they are, our revenue may be
adversely affected and our business may suffer.

We intend to initially focus our product candidate development on therapies for the treatment of liver and cardio-metabolic diseases. Our
projections of addressable patient populations that have the potential to benefit from treatment with our product candidates are based on estimates. These
estimates have been derived from a variety of sources, including the scientific literature, surveys of clinics, patient foundations or market research, and may
prove to be incorrect. Further, new studies may change the estimated incidence or prevalence of these diseases. The number of patients may turn out to be
lower than expected. Additionally, the potentially addressable patient population for our product candidates may not ultimately be amenable to treatment
with our product candidates. Our market opportunity may also be limited by future competitor treatments that enter the market. If any of our estimates are
inaccurate, the market opportunities for any of our product candidates could be significantly diminished and have an adverse material impact on our
business.

Monitoring safety of patients receiving our product candidates is challenging, which could adversely affect our ability to obtain regulatory approval
and commercialize.

For our ongoing clinical trial and planned clinical trials, we have and expect to contract with CROs and clinical trial sites experienced in the

assessment and management of toxicities arising during clinical trials.

Nonetheless, these CROs and clinical trial sites may have difficulty observing patients and treating toxicities, which may be more challenging due

to personnel changes, inexperience, shift changes, house staff coverage or related issues. This could lead to more severe or prolonged toxicities or even
patient deaths, which could result in us or the FDA delaying, suspending or terminating one or more of our clinical trials, and which could jeopardize
regulatory approval. We also expect the centers using our product candidates, if approved, on a commercial basis could similarly have difficulty in
managing adverse events. Medicines used at centers to help manage adverse side effects of our product candidates may not adequately control the side
effects and/or may have a detrimental impact on the efficacy of the treatment. Use of these medicines may increase with new physicians and centers
administering our product candidates.

Unstable market and economic conditions may have serious adverse consequences on our business and financial condition.

Global credit and financial markets have experienced extreme disruptions at various points over the last few decades, characterized by diminished

liquidity and credit availability, declines in consumer confidence, declines in economic growth, increases in unemployment rates and uncertainty about
economic stability. If another such disruption in credit and financial markets and deterioration of confidence in economic conditions occurs, our business
may be adversely affected. If the equity and credit markets were to deteriorate significantly in the future, it may make any necessary debt or equity
financing more difficult to complete, more costly, and more dilutive. Failure to secure any necessary financing in a timely manner and on favorable terms
could have a material adverse effect on our growth strategy, financial performance and share price and could require us to delay or abandon development or
commercialization plans. In addition, there is a risk that one or more of our service providers, manufacturers or other partners would not survive or be able
to meet their commitments to us under such circumstances, which could directly affect our ability to attain our operating goals on schedule and on budget.

80

 
We are subject to U.S. and certain foreign export and import controls, sanctions, embargoes, anti-corruption laws, and anti-money laundering laws and
regulations. Compliance with these legal standards could impair our ability to compete in domestic and international markets. We can face criminal
liability and other serious consequences for violations, which can harm our business.

We are subject to export control and import laws and regulations, including the U.S. Export Administration Regulations, U.S. Customs regulations,

various economic and trade sanctions regulations administered by the U.S. Treasury Department’s Office of Foreign Assets Controls, the U.S. Foreign
Corrupt Practices Act of 1977, as amended, the U.S. domestic bribery statute contained in 18 U.S.C. § 201, the U.S. Travel Act, the USA PATRIOT Act,
and other state and national anti-bribery and anti-money laundering laws in the countries in which we conduct activities. Anti-corruption laws are
interpreted broadly and prohibit companies and their employees, agents, contractors, and other collaborators from authorizing, promising, offering, or
providing, directly or indirectly, improper payments or anything else of value to recipients in the public or private sector. We may engage third parties to
sell our products sell our products outside the United States, to conduct clinical trials, and/or to obtain necessary permits, licenses, patent registrations, and
other regulatory approvals. We have direct or indirect interactions with officials and employees of government agencies or government-affiliated hospitals,
universities, and other organizations. We can be held liable for the corrupt or other illegal activities of our employees, agents, contractors, and other
collaborators, even if we do not explicitly authorize or have actual knowledge of such activities. Any violations of the laws and regulations described above
may result in substantial civil and criminal fines and penalties, imprisonment, the loss of export or import privileges, debarment, tax reassessments, breach
of contract and fraud litigation, reputational harm, and other consequences.

Changes in our effective income tax rate could adversely affect our results of operations.

As an international company, we are subject to taxation in numerous countries, states and other jurisdictions. Our effective tax rate is derived from
a combination of statutory tax rates in the various jurisdictions in which we operate. In preparing our financial statements, our effective tax rate is based on
estimates of the amount of tax that will become payable in each of these jurisdictions. Our effective tax rate may, however, differ from estimates due to
numerous factors, including a change in the mix of our profitability from country to country and changes in tax laws. The fluctuations in our effective tax
rate could have an adverse effect on our business, financial condition and results of operations and cash flows.

Risks Related to Regulatory Approvals

BIO89-100 has not received regulatory approval. If we are unable to obtain regulatory approvals to market BIO89-100 or any future product
candidates, our business will be adversely affected.

We do not expect BIO89-100 or any future product candidate to be commercially available for several years, if at all. BIO89-100 is and any future

product candidate will be subject to strict regulation by regulatory authorities in the United States and in other countries. We cannot market any product
candidate until we have completed all necessary preclinical studies and clinical trials and have obtained the necessary regulatory approvals. We do not
know whether regulatory agencies will grant approval for BIO89-100 or any future product candidate. Even if we complete preclinical studies and clinical
trials successfully, we may not be able to obtain regulatory approvals or we may not receive approvals to make claims about our products that we believe to
be necessary to effectively market our products. Data obtained from preclinical studies and clinical trials is subject to varying interpretations that could
delay, limit or prevent regulatory approval, and failure to comply with regulatory requirements or inadequate manufacturing processes are examples of
other problems that could prevent approval. The regulatory authorities in the United States and the EU have not approved any products for the treatment of
NASH, and while there are recent guidelines issued by the FDA for the development of drugs for the treatment of NASH and a FDA surrogate endpoint
table for drug approval that includes SHTG, it is unclear  whether the requirements for approval will change in the future. Any such changes may require us
to conduct new trials that could delay our timeframe and increase the costs of our programs related to BIO89-100 or any future product candidate for the
treatment of NASH or SHTG. While the FDA has approved reduction in  triglycerides levels as a surrogate endpoint for the full approval of drugs for the
treatment of SHTG, it is unclear whether this endpoint will apply to any product candidates that we develop. If such endpoint is not deemed to apply to our
product candidates, it would delay our development timeline and increase the costs of our programs for the treatment of SHTG. We have not had any
discussions with the FDA regarding a surrogate endpoint or  accelerated approval regulations. However, we currently expect that our SHTG program would
be subject to smaller clinical trials and that we may expect a relatively quick overall development timeline for this indication. These expectations are based
on a published FDA surrogate endpoint table for drug approval that includes SHTG, as well as the development path followed by other companies that
developed an SHTG therapy.

81

 
However, we do not have a Special Protocol Assessment or other agreement with the FDA on the required clinical trials needed to support an
application for approval of BIO89-100 in SHTG, and the overall clinical requirements and development timeline may be greater than expected. In addition,
we may encounter delays or rejections due to additional government regulation from future legislation, administrative action or changes in the policies of
the FDA or comparable foreign regulatory authorities. Even if the FDA or a comparable foreign regulatory authority approves a product, the approval will
be limited to those indications covered in the approval.

Even if we are able to obtain regulatory approvals for BIO89-100 or any future product candidate, if they exhibit harmful side effects after approval,
our regulatory approvals could be revoked or otherwise negatively impacted, and we could be subject to costly and damaging product liability claims.

Even if we receive regulatory approval for BIO89-100 or any future product candidates, we will have  tested them in only a small number of patients
during our clinical trials. If our applications for marketing are  approved and more patients begin to use our product, new risks and side effects associated with
our products may  be discovered. As a result, regulatory authorities may revoke their approvals. We have not had any discussions with  the FDA regarding a
surrogate endpoint or accelerated approval regulations. However, based on recent guidelines  issued by the FDA for the development of drugs for the treatment
of NASH, if BIO89-100 is approved by the FDA  based on a surrogate endpoint pursuant to section 506(c) of the Federal Food, Drug, and Cosmetic Act and
the  accelerated approval regulations (21 C.F.R. part 314, subpart H; 21 C.F.R. part 601, subpart E), consistent with  FDA guidance, we will be required to
conduct additional clinical trials establishing clinical benefit on the ultimate  outcome of NASH. If BIO89-100 is approved by the FDA for the treatment of
SHTG based on an endpoint of the  reduction of triglycerides, the FDA may still require a cardiovascular outcomes study as part of a post-marketing
authorization commitment. Such a study would be time consuming and costly and we cannot guarantee that we will  see positive results, which could result in
the revocation of the approval. Additionally, we may be required to  conduct additional clinical trials, make changes in labeling of our product, reformulate our
product or make  changes and obtain new approvals for our and our suppliers’ manufacturing facilities for BIO89-100 and any future  product candidates. We
might have to withdraw or recall our products from the marketplace. We may also  experience a significant drop in the potential sales of our product if and
when regulatory approvals for such product  are revoked. As a result, we may experience harm to our reputation in the marketplace or become subject to
lawsuits, including class actions. Any of these results could decrease or prevent any sales of our approved product  or substantially increase the costs and
expenses of commercializing and marketing our product.

The regulatory approval processes of the FDA and comparable foreign regulatory authorities are lengthy, time-consuming and inherently
unpredictable. Our inability to obtain regulatory approval for BIO89-100 or any future product candidates would substantially harm our business.

Currently, we do not have any product candidates that have received regulatory approval. The time required to obtain approval from the FDA and
comparable foreign regulatory authorities is unpredictable but typically takes many years following the commencement of preclinical studies and 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 development and may vary among
jurisdictions. It is possible that none of BIO89-100 or any future product candidates will ever obtain regulatory approval.

BIO89-100 or any future product candidate could fail to receive regulatory approval from the FDA or comparable foreign regulatory authorities for

many reasons, including:

•

•

•

•

•

disagreement with the design or implementation of our clinical trials;

failure to demonstrate that a product candidate is safe and effective for its proposed indication;

failure of clinical trials to meet the level of statistical significance required for approval;

failure to demonstrate that a product candidate’s clinical and other benefits outweigh its safety risks;

disagreement with our interpretation of data from preclinical studies or clinical trials;

82

 
 
 
 
 
 
•

•

•

the insufficiency of data collected from clinical trials of a product candidate to support the submission and filing of a BLA or other
submission or to obtain regulatory approval;

failure to obtain approval of the manufacturing processes or facilities of third-party manufacturers with whom we contract for clinical and
commercial supplies; or

changes in the approval policies or regulations that render our preclinical and clinical data insufficient for approval.

The FDA or comparable foreign regulatory authorities may require more information, including additional preclinical or clinical data to support

approval, which may delay or prevent approval and our commercialization plans, or we may decide to abandon the development program for other reasons.
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
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.

Our failure to obtain regulatory approval in international jurisdictions would prevent us from marketing our product candidates outside the United
States.

If we succeed in developing any products, we intend to market them in foreign jurisdictions in addition to the United States. In order to market and
sell our products in other jurisdictions, we must obtain separate marketing approvals and comply with numerous and varying regulatory requirements. We
may not obtain foreign regulatory approvals on a timely basis, if at all. Approval by the FDA does not ensure approval by regulatory authorities in other
countries or jurisdictions. Approval by one regulatory authority outside the United States does not ensure approval by regulatory authorities in other
countries or jurisdictions or by the FDA. If we fail to obtain approval of any of our product candidates by regulatory authorities in another country we will
be unable to commercialize our product in that country, and the commercial prospects of that product candidate and our business prospects could decline.
The approval procedure varies among countries and can involve additional testing. The time required to obtain approval may differ substantially from that
required to obtain FDA approval. The regulatory approval process outside the United States generally includes all of the risks associated with obtaining
FDA approval. In addition, in many countries outside the United States, we must secure product reimbursement approvals before regulatory authorities will
approve the product for sale in that country.

Obtaining foreign regulatory approvals and compliance with foreign regulatory requirements could result in significant delays, difficulties and
costs for us and could delay or prevent the introduction of our products in certain countries. Further, clinical trials conducted in one country may not be
accepted by regulatory authorities in other countries and regulatory approval in one country does not ensure approval in any other country, while a failure
or delay in obtaining regulatory approval in one country may have a negative effect on the regulatory approval process in others. Also, regulatory approval
for any of our product candidates may be withdrawn if we fail to comply with regulatory requirements, if problems occur after the product candidate
reaches the market or for other reasons. If we fail to comply with the regulatory requirements in international markets and fail to receive applicable
marketing approvals, our target market will be reduced and our ability to realize the full market potential of our product candidates will be harmed and our
business will be adversely affected.

Even if BIO89-100 or any future product candidate receives regulatory approval, it may still face future development and regulatory difficulties.

Even if we obtained regulatory approval for a product candidate, it would be subject to ongoing requirements by the FDA and comparable foreign

regulatory authorities governing the manufacture, quality control, further development, labeling, packaging, storage, distribution, safety surveillance,
import, export, advertising, promotion, recordkeeping and reporting of safety and other post-market information. The FDA and comparable foreign
regulatory authorities will continue to closely monitor the safety profile of any product even after approval. If the FDA, or comparable foreign regulatory
authorities, become aware of new safety information after approval of any of our product candidates, it may require labeling changes or establishment of a
risk evaluation and mitigation strategy or similar strategy, impose significant restrictions on a product’s indicated uses or marketing or impose ongoing
requirements for potentially costly post-approval studies or post-market surveillance.

83

 
 
 
 
In addition, manufacturers of drug products and their facilities are subject to continual review and periodic inspections by the FDA and other

regulatory authorities for compliance with cGMP, regulations and standards. If we or a regulatory agency discover previously unknown problems with a
product, such as adverse events of unanticipated severity or frequency, or problems with the facility where the product is manufactured, a regulatory
agency may impose restrictions on that product, the manufacturing facility or us, including requiring recall or withdrawal of the product from the market or
suspension of manufacturing. If we, our product candidates or the manufacturing facilities for our product candidates fail to comply with applicable
regulatory requirements, or undesirable side effects caused by such products are identified, a regulatory agency may:

•

•

•

•

•

•

•

•

•

•

issue safety alerts, Dear Healthcare Provider letters, press releases or other communications containing warnings about such product;

mandate modifications to promotional materials or require us to provide corrective information to healthcare practitioners;

require that we conduct post-marketing studies;

require us to enter into a consent decree, which can include imposition of various fines, reimbursements for inspection costs, required due
dates for specific actions and penalties for noncompliance;

seek an injunction or impose civil or criminal penalties or monetary fines;

suspend marketing of, withdraw regulatory approval of or recall such product;

suspend any ongoing clinical studies;

refuse to approve pending applications or supplements to applications filed by us;

suspend or impose restrictions on operations, including costly new manufacturing requirements; or

seize or detain products, refuse to permit the import or export of products or require us to initiate a product recall.

The occurrence of any event or penalty described above may inhibit our ability to commercialize our products and generate product revenue.

Advertising and promotion of any product candidate that obtains approval in the United States will be heavily scrutinized by the FDA, the
Department of Justice, the Department of Health and Human Services’ Office of Inspector General, state attorneys general, members of Congress and the
public. Violations, including promotion of our products for unapproved (or off-label) uses, are subject to enforcement letters, inquiries and investigations,
and significant civil and criminal sanctions by the government. In the United States, engaging in the impermissible promotion of our products for off-label
uses can also subject us to false claims litigation under federal and state statutes, which can lead to significant civil and criminal penalties. Additionally,
comparable foreign regulatory authorities will heavily scrutinize advertising and promotion of any product candidate that obtains approval outside of the
United States.

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 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.

84

 
 
 
 
 
 
 
 
 
 
 
Risks Relating to Intellectual Property

Our success depends upon our ability to obtain and maintain intellectual property protection for our products and technologies.

Our success will depend in significant part on our current or future licensors’, licensees’ or collaborators’ ability to establish and maintain adequate

protection of our owned and licensed intellectual property covering the product candidates we plan to develop, and the ability to develop these product
candidates and commercialize the products resulting therefrom, without infringing the intellectual property rights of others. In addition to taking other steps
to protect our intellectual property, we hold issued patents, we have applied for patents, and we intend to continue to apply for, patents with claims covering
our technologies, processes and product candidates when and where we deem it appropriate to do so. We have filed numerous patent applications both in
the United States and in certain foreign jurisdictions to obtain patent rights to inventions we have discovered, with claims directed to compositions of
matter, methods of use and other technologies relating to our programs. There can be no assurance that any of these patent applications will issue as patents
or, for those applications that do mature into patents, that the claims of the patents will exclude others from making, using or selling our product candidates
or products that compete with or are similar to our product candidates. In countries where we have not sought and do not seek patent protection, third
parties may be able to manufacture and sell our product candidates without our permission, and we may not be able to stop them from doing so.

With respect to patent rights, we do not know whether any of the pending patent applications for any of our product candidates will result in the

issuance of patents that effectively protect our technologies, processes and product candidates, or if any of our issued patents or our current or future
licensors’, licensees’ or collaborators’ issued patents will effectively prevent others from commercializing competitive technologies, processes and
products. Publications of discoveries in the scientific literature often lag behind the actual discoveries, and patent applications in the United States and
other jurisdictions are typically not published until 18 months after filing or in some cases not at all, until they are issued as a patent. Therefore, we cannot
be certain that we or our current or future licensors, licensees or collaborators were the first to make the inventions claimed in our owned or licensed
patents or pending patent applications, or that we or our current or future licensors, licensees or collaborators were the first to file for patent protection of
such inventions.

Any changes we make to our BIO89-100 or any future product candidates to cause them to have what we view as more advantageous properties

may not be covered by our existing patents and patent applications, and we may be required to file new applications and/or seek other forms of protection
for any such altered product candidates. The patent landscape surrounding the technology underlying our product candidates is crowded, and there can be
no assurance that we would be able to secure patent protection that would adequately cover an alternative to BIO89-100 or any future product candidates.

The patent prosecution process is expensive and time-consuming, and we and our current or future licensors, licensees or collaborators may not be
able to prepare, file and prosecute all necessary or desirable patent applications at a reasonable cost or in a timely manner. It is also possible that we or our
current or future licensors, licensees or collaborators will fail to identify patentable aspects of inventions made in the course of development and
commercialization activities before it is too late to obtain patent protection for them. Moreover, in some circumstances, we may not have the right to
control the preparation, filing and prosecution of patent applications, or to maintain or enforce the patents, covering technology that we license from or
license to third parties and may be reliant on our current or future licensors, licensees or collaborators to perform these activities, which means that these
patent applications may not be prosecuted, and these patents enforced, in a manner consistent with the best interests of our business. If our current or future
licensors, licensees or collaborators fail to establish, maintain, protect or enforce such patents and other intellectual property rights, such rights may be
reduced or eliminated. If our current or future licensors, licensees or collaborators are not fully cooperative or disagree with us as to the prosecution,
maintenance or enforcement of any patent rights, such patent rights could be compromised.

85

 
Similar to the patent rights of other biotechnology companies, the scope, validity and enforceability of our owned and licensed patent rights

generally are highly uncertain and involve complex legal and factual questions. The issuance of a patent is not conclusive as to its inventorship, scope,
validity or enforceability, and our patents may be challenged in the courts or patent offices in the United States and abroad. In recent years, these areas have
been the subject of much litigation in the industry. As a result, the issuance, scope, validity, enforceability and commercial value of our and our current or
future licensors’, licensees’ or collaborators’ patent rights are highly uncertain. Our and our current or future licensors’, licensees’ or collaborators’
pending and future patent applications may not result in patents being issued that protect our technology or product candidates, or products resulting
therefrom, in whole or in part, or that effectively prevent others from commercializing competitive technologies and products. The patent examination
process may require us or our current or future licensors, licensees or collaborators to narrow the scope of the claims of pending and future patent
applications, which would limit the scope of patent protection that is obtained, if any. Our and our current or future licensors’, licensees’ or collaborators’
patent applications cannot be enforced against third parties practicing the technology that is currently claimed in such applications unless and until a patent
issues from such applications, and then only to the extent the claims that issue are broad enough to cover the technology being practiced by those third
parties.

Furthermore, given the amount of time required for the development, testing and regulatory review of new product candidates, patents protecting

such candidates might expire before or shortly after the resulting products are commercialized. As a result, our owned and in-licensed patents may not
provide us with sufficient rights to exclude others from commercializing products similar or identical to ours. We expect to seek extensions of patent terms
for our issued patents, where available. This includes in the United States under the Hatch-Waxman Act, which permits a patent term extension of up to
five years beyond the original expiration date of the patent as compensation for regulatory delays. However, such a patent term extension cannot lengthen
the remaining term of a patent beyond a total of 14 years from the product’s approval date. Only one patent applicable to an approved drug is eligible for
the extension and the application for the extension must be submitted prior to the expiration of the patent. During the period of patent term extension, the
claims of a patent are not enforceable for their full scope, but are instead limited to the scope of the approved product. In addition, the applicable
authorities, including the FDA in the United States, and any comparable foreign regulatory authorities, may not agree with our assessment of whether such
extensions are available, and may refuse to grant extensions to our patents, or may grant more limited extensions than we request. In addition, we may not
be granted an extension because of, for example, failing to apply within applicable deadlines, failing to apply prior to the expiration of relevant patents or
otherwise failing to satisfy applicable requirements. If this occurs, any period during which we have the right to exclusively market our product will be
shorter than we would otherwise expect, and our competitors may obtain approval of and launch products earlier than might otherwise be the case.

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

The legal protection afforded to inventors and owners of intellectual property in countries outside of the United States may not be as protective or

effective as that in the United States and we may, therefore, be unable to acquire and enforce intellectual property rights outside the United States to the
same extent as in the United States. Whether filed in the United States or abroad, our patent applications may be challenged or may fail to result in issued
patents.

In addition, our existing patents and any future patents we obtain may not be sufficiently broad to prevent others from practicing our technologies

or from developing or commercializing competing products. Furthermore, others may independently develop or commercialize similar or alternative
technologies or drugs, or design around our patents. Our patents may be challenged, invalidated, circumvented or narrowed, or fail to provide us with any
competitive advantages. In many foreign countries, patent applications and/or issued patents, or parts thereof, must be translated into the native language. If
our patent applications or issued patents are translated incorrectly, they may not adequately cover our technologies; in some countries, it may not be
possible to rectify an incorrect translation, which may result in patent protection that does not adequately cover our technologies in those countries.

Filing, prosecuting, enforcing and defending patents on product candidates in all countries throughout the world would be prohibitively expensive,

and our intellectual property rights in some countries outside the United States are less extensive than those in the United States. In addition, the laws of
some foreign countries do not protect intellectual property rights to the same extent as federal and certain state laws in the United States.

86

 
Consequently, we may not be able to prevent third parties from practicing our inventions in all countries outside the United States, or from selling

or importing products made using our inventions in and into the United States or other jurisdictions. Competitors may use 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 United States. These products may compete with BIO89-100 or any future product
candidates and our patents or other intellectual property rights may not be effective or sufficient to prevent them from 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. This could make it difficult for us to stop the infringement of our patents or the marketing of competing
products in violation of our proprietary rights, generally. Proceedings to enforce our patent rights in foreign jurisdictions could result in substantial costs
and divert our efforts and attention from other aspects of our business, could put our patents at risk of being invalidated or interpreted narrowly, could place
our patent applications at risk of not issuing and could provoke third parties to assert claims against us or our collaborator. We may not prevail in any
lawsuits that we initiate and the damages or other remedies awarded, if any, may not be commercially meaningful.

The requirements for patentability differ and certain countries have heightened requirements for patentability, requiring more disclosure in the

patent application. In addition, certain countries have compulsory licensing laws under which a patent owner may be compelled to grant licenses to third
parties. In those countries, we may have limited remedies if patents are infringed or if we are compelled to grant a license to a third party, which could
materially diminish the value of those patents. This could limit our potential revenue opportunities. In addition, many countries limit the enforceability of
patents against government agencies or government contractors. In these countries, the patent owner may have limited remedies, which could materially
diminish the value of such patent. Accordingly, our efforts to enforce intellectual property rights around the world may be inadequate to obtain a significant
commercial advantage from the intellectual property that we own or license.

We rely on a license from Teva and a sublicense from ratiopharm to patents and know-how related to glycoPEGylation technology that are used in the
development, manufacture and commercialization of BIO89-100. Any termination or loss of significant rights, including the right to glycoPEGylation
technology, or breach, under these agreements or any future license agreement related to our product candidates, would materially and adversely affect
our ability to continue the development and commercialization of the related product candidates.

In April 2018, we entered into an Asset Transfer and License Agreement (the “FGF21 Agreement”) with Teva under which we acquired certain
patents, intellectual property and other assets relating to Teva’s glycoPEGylated FGF21 program, including BIO89-100. Under this agreement, we were
granted a perpetual,  non-exclusive (but exclusive as to BIO89-100), non-transferable, worldwide license to patents and know-how related to
glycoPEGylation technology used in the development, manufacture and commercialization of BIO89-100 and products containing BIO89-100. The FGF21
Agreement also contains numerous covenants with which we must comply, including the utilization of commercially reasonable efforts to develop and
ultimately commercialize BIO89-100, as well as certain reporting covenants and the obligation to make royalty payments, if and when BIO89-100 is
approved for commercialization. Our failure to satisfy any of these covenants could result in the termination of the FGF21 Agreement. In addition, we
entered into a Sublicense Agreement with ratiopharm (the “ratiopharm Sublicense”), under which we were granted a perpetual, exclusive, worldwide
sublicense to patents and know-how related to glycoPEGylation technology used in the development, manufacture and commercialization of BIO89-100
and products containing BIO89-100. Termination of the FGF21 Agreement or the ratiopharm Sublicense will impact our rights under the intellectual
property licensed to us by Teva and ratiopharm, respectively, including our license to glycoPEGylation technology, but will not affect  our rights under the
assets assigned to us.

87

 
Beyond this agreement, our commercial success will also depend upon our ability, and the ability of our licensors, to develop, manufacture, market

and sell our product candidates and use our proprietary technologies without infringing the proprietary rights of third parties. A third party may hold
intellectual property rights, including patent rights, that are important or necessary to the development of our product candidates. As a result, we may enter
into additional license agreements in the future. If we fail to comply with the obligations under these agreements, including payment and diligence
obligations, our licensors may have the right to terminate these agreements, in which event we may not be able to develop, manufacture, market or sell any
product that is covered by these agreements or to engage in any other activities necessary to our business that require the freedom to operate afforded by
the agreements, or we may face other penalties under the agreements.

Any of the foregoing could materially and adversely affect the value of the product candidate being developed under any such agreement.
Termination of these agreements or reduction or elimination of our rights under these agreements may result in our having to negotiate new or amended
agreements, which may not be available to us on equally favorable terms, or at all, or cause us to lose our rights under these agreements, including our
rights to intellectual property or technology important to our development programs.

Changes in patent law could diminish the value of patents in general, thereby impairing our ability to protect BIO89-100 and any future product
candidates.

As is the case with other biotechnology and pharmaceutical companies, our success is heavily dependent on intellectual property rights,
particularly patents. Obtaining and enforcing patents in the biopharmaceutical industry involves technological and legal complexity, and obtaining and
enforcing biopharmaceutical patents is costly, time-consuming and inherently uncertain. The U.S. Supreme Court in recent years has issued rulings either
narrowing the scope of patent protection available in certain circumstances or weakening the rights of patent owners in certain situations or ruling that
certain subject matter is not eligible for patent protection. In addition to increasing uncertainty with regard to our ability to obtain patents in the future, this
combination of events has created uncertainty with respect to the value of patents, once obtained. Depending on decisions by Congress, the federal courts,
the USPTO and equivalent bodies in foreign jurisdictions, the laws and regulations governing patents could change in unpredictable ways that would
weaken our ability to obtain new patents or to enforce existing patents and patents we may obtain in the future.

Patent reform laws, such as the Leahy-Smith America Invents Act (the “Leahy-Smith Act”), as well as changes in how patent laws are interpreted,
could increase the uncertainties and costs surrounding the prosecution of our patent applications and the enforcement or defense of our issued patents. The
Leahy-Smith Act made a number of significant changes to U.S. patent law. These include provisions that affect the filing and prosecution strategies
associated with patent applications, including a change from a “first-to-invent” to a “first-inventor-to-file” patent system, and a change allowing third-party
submission of prior art to the USPTO during patent prosecution and additional procedures to attack the validity of a patent by USPTO-administered post-
grant proceedings, including post-grant review, inter partes review and derivation proceedings. The USPTO has developed regulations and procedures to
govern administration of the Leahy-Smith Act, and many of the substantive changes to patent law associated with the Leahy-Smith Act and, in particular,
the “first-inventor-to-file” provisions, became effective in 2013. The Leahy-Smith Act and its implementation may increase the uncertainties and costs
surrounding the prosecution of our patent applications and the enforcement or defense of our issued patents, all of which could have a material adverse
effect on our business, financial condition and results of operations.

We may be unable to obtain intellectual property rights or technology necessary to develop and commercialize BIO89-100 and any future product
candidates.

The patent landscape around our programs is complex, and we are aware of several third-party patents and patent applications containing subject

matter that might be relevant to BIO89-100. Depending on what claims ultimately issue from these patent applications, and how courts construe the issued
patent claims, as well as depending on the ultimate formulation and method of use of BIO89-100 or any future product candidates, we may need to obtain a
license to practice the technology claimed in such patents. There can be no assurance that such licenses will be available on commercially reasonable
terms, or at all. If a third party does not offer us a necessary license or offers a license only on terms that are unattractive or unacceptable to us, we might be
unable to develop and commercialize one or more of our product candidates, which would have a material adverse effect on our business, financial
condition and results of operations. Moreover, even if we obtain licenses to such intellectual property, but subsequently fail to meet our obligations under
the relevant license agreements, or such license agreements are terminated for any other reasons, we may lose our rights to the technologies licensed under
those agreements.

88

 
The licensing or acquisition of third-party intellectual property rights is an area in which many companies operate that have interests that are in

conflict with ours, and several more established companies may pursue strategies to license or acquire third-party intellectual property rights that we may
consider attractive or necessary. These established companies may have a competitive advantage over us due to their size, capital resources and greater
clinical development and commercialization capabilities. In addition, companies that perceive us to be a competitor may be unwilling to assign or license
rights to us. We also may be unable to license or acquire third-party intellectual property rights on terms that would allow us to make an appropriate return
on our investment, or at all. If we are unable to successfully obtain rights to required third-party intellectual property rights or maintain the existing
intellectual property rights we have, we may have to abandon development of the relevant program or product candidate, which could have a material
adverse effect on our business, financial condition, results of operations and prospects.

We may become involved in lawsuits or other proceedings to protect or enforce our intellectual property, which could be expensive, time-consuming
and unsuccessful and have a material adverse effect on the success of our business.

Third parties may infringe our patents or misappropriate or otherwise violate our intellectual property rights. In the future, we may initiate legal
proceedings to enforce or defend our intellectual property rights, to protect our trade secrets or to determine the validity or scope of intellectual property
rights we own or control. Also, third parties may initiate legal proceedings against us to challenge the validity or scope of intellectual property rights we
own, control or to which we have rights. For example, generic or biosimilar drug manufacturers or other competitors or third parties may challenge the
scope, validity or enforceability of our patents, requiring us to engage in complex, lengthy and costly litigation or other proceedings. These proceedings
can be expensive and time-consuming and many of our adversaries in these proceedings may have the ability to dedicate substantially greater resources to
prosecuting these legal actions than we can. Accordingly, despite our efforts, we may not be able to prevent third parties from infringing upon or
misappropriating intellectual property rights we own, control or have rights to, particularly in countries where the laws may not protect those rights as fully
as in the United States. Litigation could result in substantial costs and diversion of management resources, which could harm our business and financial
results. In addition, if we initiated legal proceedings against a third party to enforce a patent covering a product candidate, the defendant could
counterclaim that such patent is invalid or unenforceable. In patent litigation in the United States, defendants usually assert counterclaims alleging
invalidity or unenforceability. Grounds for a validity challenge could be an alleged failure to meet any of several statutory requirements, including lack of
novelty, obviousness or non-enablement. Grounds for an unenforceability assertion could be an allegation that someone connected with prosecution of the
patent withheld relevant information from the USPTO, or made a misleading statement, during prosecution. In an infringement or declaratory judgment
proceeding, a court may decide that a patent owned by or licensed to us is invalid or unenforceable, or may refuse to stop the other party from using the
subject matter alleged to be infringing on the grounds that our patents do not cover that subject matter. An adverse result in any litigation proceeding could
put one or more of our patents at risk of being invalidated, narrowed, held unenforceable or interpreted in such a manner that would not preclude third
parties from entering the market with competing products.

Third-party pre-issuance submission of prior art to the USPTO, or opposition, derivation, revocation, reexamination, inter partes review or

interference proceedings, or other pre-issuance or post-grant proceedings or other patent office proceedings or litigation in the United States or other
jurisdictions provoked by third parties or brought by us, may be necessary to determine the inventorship, priority, patentability or validity of inventions
with respect to our patents or patent applications. An unfavorable outcome could leave our technology or product candidates without patent protection,
allow third parties to commercialize our technology or product candidates and compete directly with us, without payment to us, or could require us to
obtain license rights from the prevailing party in order to be able to manufacture or commercialize our product candidates without infringing third-party
patent rights. Our business could be harmed if the prevailing party in such a case does not offer us a license on commercially reasonable terms, or at all.
Even if we obtain a license, it may be non-exclusive, thereby giving our competitors access to the same technologies licensed to us. In addition, if the
breadth or strength of protection provided by our patents and patent applications is threatened, it could dissuade companies from collaborating with us to
license, develop or commercialize current or future product candidates. Even if we successfully defend such litigation or proceeding, we may incur
substantial costs and our defense may distract our management and other employees.

89

 
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 this type of litigation. In addition, many foreign jurisdictions have rules of
discovery that are different than those in the United States and that may make defending or enforcing our patents extremely difficult. 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.

Third parties may initiate legal proceedings against us alleging that we infringe their intellectual property rights or we may initiate legal proceedings
against third parties to challenge the validity or scope of intellectual property rights controlled by third parties, the outcome of which would be
uncertain and could have a material adverse effect on our business.

Our commercial success depends upon our ability to develop, manufacture, market and sell BIO89-100 and any future product candidates that we

may develop and use our proprietary technologies without infringing, misappropriating or otherwise violating the intellectual property and proprietary
rights of third parties. The biotechnology and pharmaceutical industries are characterized by extensive litigation regarding patents and other intellectual
property rights. Third parties may initiate legal proceedings against us alleging that we infringe their intellectual property rights or we may initiate legal
proceedings against third parties to challenge the validity or scope of intellectual property rights controlled by third parties, including in oppositions,
interferences, revocations, reexaminations, inter partes review or derivation proceedings before the USPTO or its counterparts in other jurisdictions. These
proceedings can be expensive and time-consuming and many of our adversaries in these proceedings may have the ability to dedicate substantially greater
resources to prosecuting these legal actions than we can.

We could be found liable for monetary damages, including treble damages and attorneys’ fees, if we are found to have willfully infringed a patent

of a third party. A finding of infringement could prevent us from commercializing our BIO89-100 or any future product candidates or force us to cease
some of our business operations, which could materially harm our business.

We may not be aware of all third-party intellectual property rights potentially relating to BIO89-100 or any future product candidates and
technologies. We are not aware of any facts that would lead us to conclude that the valid and enforceable claims of any third-party patents would
reasonably be interpreted to cover our product candidates. As to pending third-party applications, we cannot predict with any certainty which claims will
issue, if any, or the scope of such issued claims. Even if we believe third-party intellectual property claims are without merit, there is no assurance that a
court would find in our favor on questions of infringement, validity, enforceability or priority. A court of competent jurisdiction could hold that these third-
party patents are valid, enforceable and infringed, which could materially and adversely affect our ability to commercialize any product candidates we may
develop and any other product candidates or technologies covered by the asserted third-party patents. In order to successfully challenge the validity of any
such U.S. patent in federal court, we would need to overcome a presumption of validity. As this burden is a high one requiring us to present clear and
convincing evidence as to the invalidity of any such U.S. patent claim, there is no assurance that a court of competent jurisdiction would invalidate the
claims of any such U.S. patent. If any such third-party patents (including those that may issue from such applications) were successfully asserted against us
or other commercialization partners and we were unable to successfully challenge the validity or enforceability of any such asserted patents, then we and
other commercialization partners may be prevented from commercializing our product candidates, or may be required to pay significant damages,
including treble damages and attorneys’ fees if we are found to willfully infringe the asserted patents, or obtain a license to such patents, which may not be
available on commercially reasonable terms, or at all. Even if we were able to obtain a license, it could be non-exclusive, thereby giving our competitors
and other third parties access to the same technologies licensed to us, and it could require us to make substantial licensing and royalty payments. Any of the
foregoing would have a material adverse effect on our business, financial condition and operating results.

90

 
Although we have reviewed certain third-party patents and patent filings that we believe may be relevant to our therapeutic candidates or products,

we have not conducted a freedom-to-operate search or analysis for any of our therapeutic candidates or products, and we may not be aware of patents or
pending or future patent applications that, if issued, would block us from commercializing our therapeutic candidates or products. Thus, we cannot
guarantee that our therapeutic candidates or products, or our commercialization thereof, do not and will not infringe any third party’s intellectual property.

We may be subject to claims by third parties asserting misappropriation of intellectual property, or claiming ownership of what we regard as our own
intellectual property.

Although we seek to ensure that our employees do not use the proprietary information or know-how of others in their work for us, we may be

subject to claims that we or these employees have used or disclosed confidential information or intellectual property, including trade secrets or other
proprietary information, of any such employee’s former employer, or that third parties have an interest in our patents as an inventor or co-inventor.
Litigation may be necessary to defend against these claims. If we fail in prosecuting or defending any such claims, in addition to paying monetary
damages, we may lose valuable intellectual property rights or the services of personnel or sustain other damages. Such intellectual property rights could be
awarded to a third party, and we could be required to obtain a license from such third party to commercialize our technology or products. Such a license
may not be available on commercially reasonable terms, or at all. Even if we successfully prosecute or defend against such claims, litigation could result in
substantial costs and distract management.

In addition, while it is our policy to require our employees and contractors who may be involved in the conception or development of intellectual

property to execute agreements assigning such intellectual property to us, we may be unsuccessful in executing such an agreement with each party who, in
fact, conceives or develops intellectual property that we regard as our own. The assignment of intellectual property rights may not be self-executing, or the
assignment agreements may be breached, and we may be forced to bring claims against third parties, or defend claims that they may bring against us, to
determine the ownership of what we regard as our intellectual property. Such claims could have a material adverse effect on our business, financial
condition, results of operations and prospects.

Our inability to protect our confidential information and trade secrets would harm our business and competitive position.

In addition to seeking patents for some of our technology and product candidates, we also rely substantially on trade secrets, including unpatented

know-how, technology and other proprietary materials and information, to maintain our competitive position. We seek to protect these trade secrets, in part,
by entering into non-disclosure and confidentiality agreements with parties who have access to them, such as our employees, corporate collaborators,
outside scientific collaborators, contract manufacturers, consultants, advisors and other third parties. We also enter into confidentiality and invention or
patent assignment agreements with our employees and consultants. However, these steps may be inadequate, we may fail to enter into agreements with all
such parties or any of these parties may breach the agreements and disclose our trade secrets and there may be no adequate remedy available for such
breach of an agreement. We cannot assure you that our trade secrets will not be disclosed or that we can meaningfully protect our trade secrets. Enforcing a
claim that a party illegally disclosed or misappropriated a trade secret is difficult, expensive and time consuming, and the outcome is unpredictable. In
addition, some courts both within and outside the United States may be less willing, or unwilling, to protect trade secrets. If a competitor lawfully obtained
or independently developed any technology or information that we protect as trade secret, we would have no right to prevent such competitor from using
that technology or information to compete with us, which could harm our competitive position.

91

 
Intellectual property rights do not necessarily address all potential threats.

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. For example:

•

•

•

•

•

•

•

•

•

•

others may be able to make products that are similar to BIO89-100 and any future product candidates we may develop or utilize similar
technology but that are not covered by the claims of the patents that we exclusively license or may own in the future;

we, or our future collaborators, might not have been the first to make the inventions covered by the issued patents and pending patent
applications that we exclusively license or may own in the future;

we, or our future collaborators, might not have been the first to file patent applications covering certain of our or their inventions;

others may independently develop similar or alternative technologies or duplicate any of our technologies without infringing our owned or
exclusively licensed intellectual property rights;

it is possible that our pending patent applications or those that we may file in the future will not result in issued patents;

issued patents that we hold rights to may be held invalid or unenforceable, including 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 major commercial markets in which we do not have
sufficient patent rights to stop such sales;

we may not develop additional proprietary technologies that are patentable;

the patents of others may be asserted against our product candidates and technologies in a manner that harms our business; and

we may choose not to file a patent application in order to maintain certain trade secrets or know-how, and a third party may subsequently
file a patent covering such trade secrets or know-how.

Should any of these events occur, they could have a material adverse effect on our business, financial condition, results of operations and prospects.

If our trademarks and trade names are not maintained and adequately protected, we may not be able to build name recognition in our markets of
interest, and our business may be adversely affected.

Failure to obtain trademark registrations in the future, could limit our ability to protect and enforce our trademarks and impede our marketing

efforts in the countries in which we operate. We may not be able to protect our rights to trademarks and trade names which we may need to build name
recognition with potential partners or customers in our markets of interest. As a means to enforce any future trademark rights and prevent infringement, we
may be required to file trademark claims against third parties or initiate trademark opposition proceedings. This can be expensive, and strain the financial
resources of a company of our size, and time-consuming, and we may not be successful in enforcing our trademark rights. In addition, our registered or
unregistered trademarks or trade names may be challenged, infringed, circumvented, declared generic or determined to be infringing on other marks.

Future trademark applications in the United States and in other foreign jurisdictions where we may file may not be allowed or may subsequently be
opposed. Even if these applications result in registration of trademarks, third parties may challenge our use or registration of these trademarks in the future.
Over the long term, if we are unable to establish name recognition based on our trademarks and trade names, then we may not be able to compete
effectively and our business may be adversely affected.

Risks Related to Ownership of Our Common Stock

The price of our common stock may be volatile, and you may lose all or part of your investment.

The market price of our common stock could fluctuate significantly, and you may not be able to resell your shares at or above the price you paid

for your shares. Those fluctuations could be based on various factors in addition to those otherwise described in this prospectus, including those described
in these “Risk Factors.” Any of these factors may result in large and sudden changes in the volume and trading price of our common stock. In the past,
following periods of volatility in the market price of a company’s securities, stockholders have often instituted securities class action litigation against that
company. If we were involved in a class action suit, it could divert the attention of management, result in negative press reports and, if adversely
determined, have a material adverse effect on our results of operations and financial condition.

In addition, the stock market, in general, and the stocks of many small healthcare and biotechnology companies, in particular, have experienced

extreme price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of these companies. Broad market
and industry factors may negatively affect the market price of our common stock, regardless of our actual operating performance. Further, a decline in the
broader financial markets and related factors beyond our control may cause the price of our common stock to decline rapidly and unexpectedly.

Sales of our common stock, or the perception that such sales may occur, could depress the price of our common stock.

Sales of a substantial number of shares of our common stock in the public market, or the perception that such sales may occur, could depress the
market price of our common stock. Holders of an aggregate of 7,077,366 shares of our common stock have rights, subject to certain conditions, to require
us to file registration statements covering their shares or to include their shares in registration statements that we may file for ourselves or other
stockholders. In addition, we have filed a registration statement registering under the Securities Act the shares of our common stock reserved for issuance
under our 2019 Equity Incentive Plan, including shares issuable upon exercise of outstanding options. These shares can be freely sold in the public market
upon issuance, subject to volume limitations applicable to affiliates and the lock-up agreements described above. Further, as opportunities present
themselves, we may enter into financing or similar arrangements in the future, including the issuance of debt or equity securities. If we issue common stock
or securities convertible into our common stock, our common stockholders would experience additional dilution and, as a result, the price of our common
stock may decline.

Our directors, executive officers and current holders of 5% or more of our capital stock have substantial control over our company, which could limit
your ability to influence the outcome of matters subject to stockholder approval, including a change of control.

As of March 1, 2020, our executive officers, directors and other holders of 5% or more of our common stock beneficially owned a majority of our
outstanding common stock. As a result, our executive officers, directors and other holders of 5% or more of our common stock, if they act, will be able to
influence or control matters requiring approval by our stockholders, including the election of directors and the approval of mergers, acquisitions or other
extraordinary transactions. In addition, our current directors, executive officers and other holders of 5% or more of our common stock, acting together,
would have the ability to control the management and affairs of our company. They may also have interests that differ from yours and may vote in a way
with which you disagree and that may be adverse to your interests. This concentration of ownership may have the effect of delaying, preventing or
deterring a change of control of our company, could deprive our stockholders of an opportunity to receive a premium for their shares of our common
stock as part of a sale of our company and could affect the market price of our common stock.

If securities or industry analysts do not publish research, or publish inaccurate or unfavorable research, about our stock or business, the price of our
common stock and trading volume could decline.

The trading market for our common stock depends, in part, on the research and reports that securities or industry analysts publish about us or our
business. If one or more of the analysts who cover us downgrade our stock or publish inaccurate or unfavorable research about our business, demand for
our common stock could decrease and the price of our common stock could decline. In addition, if our operating results fail to meet the forecast of analysts,
the price of our common stock would likely decline. If one or more of these analysts cease coverage of our company or fail to publish reports on us
regularly, demand for our stock could decrease, which might cause the price of our common stock and trading volume to decline.

93

 
We have identified material weaknesses in our internal control over financial reporting. If our remediation of the material weaknesses is not effective,
or if we experience additional material weaknesses or otherwise fail to maintain an effective system of internal controls in the future, we may not be
able to produce timely and accurate financial statements, and we or our independent registered public accounting firm may conclude that our internal
control over financial reporting is not effective, which could adversely affect our investors’ confidence and our stock price.

Prior to our initial public offering, we were a private company and were not required to test our internal controls on a systematic basis. As an

emerging growth company under the JOBS Act, our management will be required to report upon the effectiveness of our internal control over financial
reporting under Section 404 (“Section 404”) of the Sarbanes-Oxley Act of 2002, as amended (the “Sarbanes-Oxley Act”) beginning with our Annual
Report on Form 10-K for the year ending December 31, 2020. Our independent registered public accounting firm is not required to formally attest to the
effectiveness of our internal control over financial reporting until the date we are no longer an emerging growth company and reach accelerated filer status.

Effective internal controls over financial reporting are necessary for us to provide reliable financial information and, together with adequate
disclosure controls and procedures, are designed to prevent fraud. Any failure to implement required new or improved controls, or difficulties encountered
in their implementation, could cause us to fail to meet our reporting obligations. In addition, any testing by us conducted in connection with Section 404, or
any subsequent testing by our independent registered public accounting firm, may reveal deficiencies in our internal controls over financial reporting that
are deemed to be material weaknesses or that may require prospective or retroactive changes to our consolidated financial statements or identify other areas
for further attention or improvement. 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.

In connection with our financial statement close process for 2018, we identified material weaknesses in the design and operating effectiveness of

our internal control over financial reporting.

These material weaknesses related to the following:

•

•

We did not have an internal finance department. Consequently, we lacked sufficient personnel with an appropriate level of knowledge and
requisite U.S. generally accepted accounting principles expertise to identify, evaluate and account for complex and non-routine transaction
and an adequate supervisory review structure that is needed to comply with financial reporting requirements.

We did not have an adequate assessment of risks that could significantly impact internal control over financial reporting and did not
effectively design and monitor controls in response to the risks of material misstatement.

We have implemented and are in the process of implementing measures designed to improve our disclosure controls and procedures and internal

control over financial reporting to address the underlying causes of these material weaknesses, including the implementation of appropriate segregation of
duties, formalization of accounting policies and controls, implementation of accounting systems to automate manual processes, formalization of our hiring
practices, hiring of our Chief Financial Officer, principal accounting officer and additional qualified accounting and finance personnel, recruitment of a
new audit committee chair and financial expert (following the resignation of Tomer Kariv, our audit committee chair and financial expert, from our board
of directors in December 2019) and engagement of financial consultants to enable the implementation of internal controls over financial reporting.

Our remediation efforts are ongoing. While we believe that these efforts have improved and will continue to improve our internal control over

financial reporting, remediation of the material weaknesses will require validation and testing of the design and operating effectiveness of internal controls
over a sustained period of financial reporting cycles. We cannot assure you that these measures will significantly improve or remediate the material
weaknesses described above. We, and our independent registered public accounting firm, were not required to perform an evaluation of our internal control
over financial reporting as of December 31, 2019 in accordance with the provisions of the Sarbanes-Oxley Act. Accordingly, we cannot assure you that we
have identified all material weaknesses or that there will not be additional material weaknesses or deficiencies that we will identify.

94

 
 
 
We are required to comply with Section 404, which requires management to certify financial and other information in our quarterly and annual

reports and provide an annual management report on the effectiveness of our internal control over financial reporting commencing with our second annual
report. To achieve compliance with Section 404 we will need to continue to dedicate internal resources, outside consultants and continue to execute a
detailed work plan to assess and document the adequacy of internal control over financial reporting, continue steps to improve control processes, as
appropriate, validate through testing that controls are functioning as documented and implement a continuous reporting and improvement process for
internal control over financial reporting. Despite our efforts, there is a risk that we will not be able to conclude, within the prescribed timeframe or at all,
that our internal control over financial reporting is effective as required by Section 404 and material weaknesses may still exist.  We also cannot assure you
that there will not be additional material weaknesses or significant deficiencies in our internal controls in the future. In the event that we are not able to
successfully remediate the existing material weaknesses in our internal control over financial reporting or demonstrate compliance with the Sarbanes-Oxley
Act, that our internal control over financial reporting is perceived as inadequate or that we are unable to produce timely or accurate consolidated financial
statements, investors may lose confidence in our operating results, our stock price could decline and we may not be able to remain listed on The Nasdaq
Global Market.

We have and will continue to incur increased costs as a result of operating as a public company, and our management will devote substantial time to
new compliance initiatives.

As a public company, we have and will continue to incur significant legal, accounting and other expenses that we did not incur as a private

company, and these expenses may increase even more after we are no longer an emerging growth company. As a public company, we are subject to the
reporting requirements of the Exchange Act, the Sarbanes-Oxley Act, the Dodd-Frank Wall Street Reform and Protection Act, as well as rules adopted, and
to be adopted, by the SEC and Nasdaq. Our management and other personnel will need to devote a substantial amount of time to these compliance
initiatives. Moreover, we expect these rules and regulations to substantially increase our legal and financial compliance costs and to make some activities
more time-consuming and costly.

The increased costs will increase our net loss. For example, we expect these rules and regulations to make it more difficult and more expensive for
us to obtain director and officer liability insurance and we may be forced to accept reduced policy limits or incur substantially higher costs to maintain the
same or similar coverage. We cannot predict or estimate the amount or timing of additional costs we may incur to respond to these requirements. The
impact of these requirements could also make it more difficult for us to attract and retain qualified persons to serve on our board of directors, our board
committees or as executive officers.

We are an emerging growth company, as defined in the Securities Act, and we cannot be certain if the reduced disclosure requirements applicable to
emerging growth companies will make our common stock less attractive to investors.

We are an emerging growth company, as defined in Section 2(a) of the Securities Act, as modified by the JOBS Act, and we may take advantage of

certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies, including
relief from the auditor attestation requirements of Section 404 less extensive disclosure obligations regarding executive compensation in our registration
statements, periodic reports and proxy statements, exemptions from the requirements to hold a nonbinding advisory vote on executive compensation, and
exemptions from stockholder approval of any golden parachute payments not previously approved. As a result, our stockholders may not have access to
certain information that they may deem important. We could be an emerging growth company for up to five years, although circumstances could cause us
to lose that status earlier.

In addition, the JOBS Act also provides that an emerging growth company can take advantage of the extended transition period provided in the

Securities Act for complying with new or revised accounting standards. An emerging growth company can therefore delay the adoption of certain
accounting standards until those standards would otherwise apply to private companies. We have elected to avail ourselves of this exemption and, as a
result, will not be subject to the same implementation timing for new or revised accounting standards as for other public companies that are not emerging
growth companies, which may make comparison of our consolidated financial statements to those of other public companies more difficult.

We cannot predict if investors will find our common stock less attractive because we may rely on these exemptions. If some investors find our

common stock less attractive as a result, there may be a less active trading market for our common stock and the price of our common stock may be more
volatile.

Because we do not expect to pay dividends in the foreseeable future, you must rely on price appreciation of our common stock for return on your
investment.

We intend to retain most, if not all, of our available funds and earnings to fund the development and growth of our business. As a result, we do not

expect to pay any cash dividends in the foreseeable future.

Therefore, you should not rely on an investment in our common stock as a source for any future dividend income.

Our board of directors has significant discretion as to whether to distribute dividends and in what amounts. Even if our board of directors decides

to declare and pay dividends, the timing, amount and form of future dividends, if any, will depend on, among other matters, our future results of operations
and cash flow, our capital requirements and surplus, the amount of distributions, if any, received by us from our subsidiaries, our financial condition,
contractual restrictions and other factors deemed relevant by our board of directors.

Our amended and restated certificate of incorporation, amended and restated bylaws and Delaware law could prevent a third party from acquiring us
(even if an acquisition would benefit our stockholders), may limit the ability of our stockholders to replace our management and limit the price that
investors might be willing to pay for shares of our common stock.

Our amended and restated certificate of incorporation and our amended and restated bylaws could have the effect of making it more difficult for a

third party to acquire, or of discouraging a third party from attempting to acquire, control of us. These provisions could delay or prevent a change in control
of the company and could limit the price that investors might be willing to pay in the future for shares of our common stock. These provisions, among other
things.

provide that shareholders can remove directors only for cause and only upon the approval of not less than 662/3 of all outstanding shares of
our voting stock;

require the approval of not less than 662/3 of all outstanding shares of our voting stock to amend our bylaws and specific provisions of our
certificate of incorporation; and

As a Delaware corporation, we are subject to the anti-takeover provisions of Section 203 of the Delaware General Corporation Law, which
prohibits a Delaware corporation from engaging in a business combination specified in the statute with an interested stockholder (as defined in the statute)
for a period of three years after the date of the transaction in which the person first becomes an interested stockholder, unless the business combination is
approved in advance by a majority of the independent directors or by the holders of at least two-thirds of the outstanding disinterested shares. The
application of Section 203 of the Delaware General Corporation Law could also have the effect of delaying or preventing a change of control of us.

Our amended and restated certificate of incorporation provides that the Court of Chancery of the State of Delaware and the federal district courts of
the United States will be the 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 certificate of incorporation provides that the Court of Chancery of the State of Delaware is the exclusive forum for the
following types of actions or proceedings under Delaware statutory or common law: any derivative action or proceeding brought on our behalf; any action
asserting a breach of a fiduciary duty; any action asserting a claim against us arising pursuant to the Delaware General Corporation Law, our amended and
restated certificate of incorporation or our amended and restated bylaws; or any action asserting a claim against us that is governed by the Delaware
internal affairs doctrine. This provision would not apply to claims brought to enforce a duty or liability created by the Exchange Act or any other claim for
which the federal courts have exclusive jurisdiction. Our amended and restated certificate of incorporation provides further that the federal district courts of
the United States will be the exclusive forum for resolving any complaint asserting a cause of action arising under the Securities Act, subject to and
contingent upon a final adjudication in the State of Delaware of the enforceability of such exclusive forum provision. These choice of forum provisions
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.
If a court were to find the choice of forum provision contained in our amended and restated certificate of incorporation to be inapplicable or unenforceable
in an action, we may incur additional costs associated with resolving such action in other jurisdictions, which could harm our business. For example, under
the Securities Act, federal courts have concurrent jurisdiction over all suits brought to enforce any duty or liability created by the Securities Act, and
investors cannot waive compliance with the federal securities laws and the rules and regulations thereunder, and the Court of Chancery of the State of
Delaware recently determined that the exclusive forum provision of federal district courts of the United States for resolving any complaint asserting a cause
of action arising under the Securities Act is not enforceable. However, this decision may be reviewed and ultimately overturned by the Delaware Supreme
Court. If the Court of Chancery’s decision were to be overturned, we would enforce the federal district court exclusive forum provision in our amended and
restated certificate of incorporation.

Item 1B. Unresolved Staff Comments.

None.

Item 2. Properties.

We lease office space, which consists of approximately 1,600 square feet located at 6 Hamada Street, Herzliya, 4673340, Israel. This lease expires
on April 30, 2020. We also lease office space at 142 Sansome Street, San Francisco, California 94104, which consists of approximately 3,600 square feet.
This lease expires on January 14, 2022. We believe that our current spaces are adequate for our needs. We also believe we will be able to obtain additional
space, as needed, on commercially reasonable terms.

Item 3. Legal Proceedings.

We are currently not a party to any material legal proceedings. From time to time, we may become involved in legal proceedings arising in the

ordinary course of our business. Regardless of outcome, litigation can have an adverse impact on us due to defense and settlement costs, diversion of
management resources, negative publicity, reputational harm and other factors, and there can be no assurances that favorable outcomes will be obtained.

Item 5. Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities.

Market Information

Our common stock is traded on The Nasdaq Global Market under the symbol “ETNB.”

As of March 1, 2020, there were approximately 11 stockholders of record of our common stock.

Dividend Policy

We have never declared or paid cash dividends on our capital stock and have no present intention to pay cash dividends on our common stock for

the foreseeable future. Any determination to pay dividends to holders of our common stock will be at the discretion of our board of directors and will
depend on many factors, including our financial condition, results of operations, liquidity, earnings, projected capital and other cash requirements, legal
requirements, restrictions in the agreements governing any indebtedness we may enter into, business prospects and other factors that our board of directors
deems relevant.

Use of Proceeds from our Initial Public Offering

On November 13, 2019, we completed our IPO, pursuant to which we issued and sold an aggregate of 6,100,390 shares of common stock
(inclusive of 795,703 shares pursuant to the underwriters’ option to purchase additional shares) at the IPO price of $16.00 per share. The aggregate gross
proceeds from our IPO were $97.6 million, and the net proceeds were $87.7 million after deducting underwriting discounts and commissions of $6.8
million and other offering expenses of $3.1 million. The offer and sale of the shares of common stock in the IPO were registered pursuant to registration
statements on Form S-1 (File Nos. 333-234174 and 333-234617), which the SEC declared effective on November 8, 2019. No offering expenses were paid
directly or indirectly to any of our directors or officers (or their associates) or persons owning 10% or more of any class of our equity securities or to any
other affiliates. The underwriters for our IPO were BofA Securities, Inc., SVB Leerink LLC, RBC Capital Markets, LLC, and Oppenheimer & Co. Inc.

There has been no material change in the intended use of proceeds from our IPO as described in our final prospectus filed with the SEC pursuant to

Rule 424(b)(4) on November 12, 2019.

Item 6. Selected Financial Data.

We are a smaller reporting company, as defined by Rule 12b-2 under the Securities and Exchange Act of 1934 and in Item 10(f)(1) of Regulation

S-K, and are not required to provide the information under this item.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

You should read the following discussion and analysis of our financial condition and results of operations together with our consolidated financial
statements and related notes and other financial information included elsewhere in this Annual Report on Form 10-K. Some of the information contained
in this discussion and analysis includes forward-looking statements that involve risks and uncertainties. Our actual results could differ materially from
those described in or implied by these forward-looking statements. Factors that could cause or contribute to such differences include, but are not limited to,
those identified below and those discussed in the section titled “Risk Factors” included elsewhere in this Annual Report on Form 10-K.

Overview

We are a clinical-stage biopharmaceutical company focused on the development and commercialization  of innovative therapies for the treatment of
liver and cardio-metabolic diseases. Our lead product candidate, BIO89-100, a specifically engineered glycoPEGylated analog of FGF21, is currently being
developed for the treatment of NASH. NASH is a severe form of NAFLD, characterized by inflammation and fibrosis in the liver that can progress to
cirrhosis, liver failure, HCC and death. There are currently no approved products for the treatment of NASH. FGF21 is a clinically-validated mechanism
that has been shown in humans to reduce steatosis and address cardio-metabolic dysregulation. We believe BIO89-100 may be a differentiated FGF21
therapy based on its robust and durable biological effects and a favorable tolerability profile, as well as its potential for a longer dosing interval. Combining
these characteristics with the ability to address the key liver pathologies in NASH, as well as the underlying metabolic dysregulation in NASH patients,
BIO89-100 has the  potential to become a mainstay of NASH therapy. We successfully completed a Phase 1a, first-in-human, SAD clinical trial with 58
healthy volunteers. The magnitude and significance of BIO89-100’s biological effects after a single dose on lipid parameters were robust and durable. In
July 2019, we initiated our POC Phase 1b/2a clinical trial in patients with NASH or patients with NAFLD and a high risk of NASH and we expect to report
topline data in the second half of 2020. We also intend to develop BIO89-100 for the treatment of SHTG, a condition identified by severely elevated levels
of triglycerides (greater than or equal to 500 mg/dL), which is associated with an increased risk of NASH, cardiovascular events and acute pancreatitis. We
expect to initiate our Phase 2 trial in SHTG patients in the first half of 2020 in order to evaluate the ability of BIO89-100 to reduce fasting plasma
triglyceride levels compared to baseline levels and to report topline data in the first half of 2021. Based on FDA guidance for the development of SHTG
treatments, as well as the regulatory path followed by other companies that have successfully developed SHTG therapies, we believe that a combination of
smaller clinical trials and shorter development timelines could mean that SHTG potentially represents a quicker path to  market for BIO89-100. We believe
BIO89-100 has the potential to address multiple drivers underlying metabolic dysregulation, which would make it an ideal candidate for selected liver and
cardio-metabolic diseases.

We commenced operations in 2018 and have devoted substantially all of our resources to organizing and staffing our company, business planning,

raising capital, acquiring our initial product candidate, BIO89-100, and licensing certain related technology, conducting research and development
activities, including preclinical studies and early clinical trials, and providing general and administrative support for these operations. We have funded our
operations since our inception to December 31, 2019 through the issuance and sale of capital stock. As of December 31, 2019, our cash and cash
equivalents totaled $93.3 million. Based on our current operating plan, we believe that our cash and cash equivalents will be sufficient to meet our
anticipated cash requirements into the second half of 2021.

On November 8, 2019, our Registration Statements on Form S-1 (File No. 333-234174 and 333-234617) relating to our IPO, were declared
effective by the SEC. Pursuant to the Registration Statements, we issued and sold an aggregate of 6,100,390 shares of common stock (inclusive of 795,703
shares pursuant to the underwriters’ option to purchase additional shares) at a price of $16.00 per share for aggregate cash proceeds of $87.7 million, net of
underwriting discounts and commissions and estimated offering costs. Both the sale and issuance of 5,304,687 shares in the IPO and the sale and issuance
of an additional 795,703 shares pursuant to the underwriters’ option to purchase additional shares closed on November 13, 2019. Upon the closing of the
IPO, all outstanding shares of convertible preferred stock automatically converted into 7,077,366 shares of common stock. Subsequent to the closing of the
IPO, there were no shares of preferred stock outstanding.

99

 
We have incurred net losses since our inception. Our net losses were $57.4 million and $16.2 million for 2019 and the period from January 18

(inception) to December 31, 2018, respectively. As of December 31, 2019, we had an accumulated deficit of $73.6 million. We expect to continue to incur
significant expenses and increasing operating losses as we advance BIO89-100 and any future product candidates through clinical trials, seek regulatory
approval for BIO89-100 and any future product candidates, expand our clinical, regulatory, quality, manufacturing and commercialization capabilities,
protect our intellectual property, prepare for and, if approved, proceed to commercialization of BIO89-100 and any future product candidates, expand our
general and administrative support functions, including hiring additional personnel, and incur additional costs associated with operating as a public
company. Our net losses may fluctuate significantly from quarter-to-quarter and year-to-year, depending on the timing of our clinical trials and our
expenditures on other research and development activities.

We have never generated revenue and do not expect to generate revenue from product sales unless and until we successfully complete development

and obtain regulatory approval for BIO89-100, which we expect will not be for at least several years, if ever. Accordingly, until such time as we can
generate significant revenue from sales of BIO89-100, if ever, we expect to finance our cash needs through a combination of public or private equity
offerings, debt financings or other capital sources, including potential collaborations, licenses and other similar arrangements. However, we may be unable
to raise additional funds or enter into such other arrangements when needed on favorable terms or at all. Our failure to raise capital or enter into such other
arrangements when needed would have a negative impact on our financial condition and could force us to delay, limit, reduce or terminate our product
development or future commercialization efforts or grant rights to develop and market product candidates that we would otherwise prefer to develop and
market ourselves.

Reorganization

We were incorporated in January 2018 in Israel under the name 89Bio Ltd. 89bio, Inc. was incorporated in June 2019 for the purpose of an internal

reorganization transaction. In September 2019, all of the equity holders of 89Bio Ltd. exchanged 100% of the equity of 89Bio Ltd. for 100% of the equity
of 89bio, Inc (the “Reorganization”). Following this reorganization, 89Bio Ltd.  became a wholly owned subsidiary of 89bio, Inc. The Reorganization was
retrospectively adjusted to inception given the transaction was between entities under common control.

Agreements with Teva

In April 2018, we entered into the FGF21 Agreement with Teva, under which we acquired certain patents, intellectual property and other assets

relating to Teva’s glycoPEGylated FGF21 program, including BIO89-100. Under the FGF21 Agreement, Teva also granted us a perpetual, non-exclusive
(but exclusive as to BIO89-100), non-transferable, worldwide license to patents and know-how related to glycoPEGylation technology for use in the
research, development, manufacture and commercialization of BIO89-100 and products containing BIO89-100. We also entered into an Asset Transfer and
License Agreement with Teva under which we acquired from Teva certain patents, intellectual property and other assets relating to Teva’s development
program of small molecule inhibitors of FASN (the “FASN Agreement” and collectively with the FGF21 Agreement, the “Teva Agreements”).

Pursuant to the Teva Agreements, we paid Teva a nonrefundable upfront payment of $6.0 million in 2018. In addition, we are required to make

certain payments to Teva under each of the Teva Agreements of up to $2.5 million for the achievement of certain development milestones, and additional
payments of up to $65.0 million upon achievement of certain commercial milestones, for a total under both Teva Agreements of up to $135.0 million. We
are also obligated to pay Teva tiered royalties at percentages in the low-to-mid single-digits on worldwide net sales of products containing BIO89-100 or
FASN.

The assets acquired from Teva did not meet the definition of a business and therefore, this acquisition was treated as an asset acquisition for

accounting purposes. In addition, we recorded the total consideration transferred to Teva in connection with this acquisition as research and development
expense because the acquired technology represented in-process research and development and had no alternative future use.

Components of Results of Operations

Research and Development Expenses

Research and development expenses consist primarily of costs incurred for the development of our lead product candidate, BIO89-100. Our

research and development expenses consist primarily of external costs related to preclinical and clinical development, including costs related to acquiring
patents and intellectual property, expenses incurred under license agreements and agreements with contract research organizations and consultants, costs
related to acquiring and manufacturing clinical trial materials, including under agreements with contract manufacturing organizations and other vendors,
costs related to the preparation of regulatory submissions and expenses related to laboratory supplies and services, as well as personnel costs. Personnel
costs consist of salaries, employee benefits and share-based compensation for individuals involved in research and development efforts.

We expense all research and development expenses in the periods in which they are incurred. We accrue for costs incurred as the services are being
provided by monitoring the status of specific activities and the invoices received from our external service providers. We adjust our accrual as actual costs
become known.

Payments associated with licensing agreements to acquire licenses to develop, use, manufacture and commercialize products that have not reached
technological feasibility and do not have alternate commercial use are expensed as incurred. Where contingent milestone payments are due to third parties
under research and development arrangements or license agreements, the milestone payment obligations are expensed when the milestone results are
probable and estimable, which is generally upon achievement of milestones.

We expect our research and development expenses to increase substantially for the foreseeable future as we continue the development of BIO89-
100 and continue to invest in research and development activities. The process of conducting the necessary clinical research to obtain regulatory approval
is costly and time consuming, and the successful development of BIO89-100 and any future product candidates is highly uncertain. To the extent that
BIO89-100 continues to advance into larger and later stage clinical trials, our expenses will increase substantially and may become more variable. The
actual probability of success for BIO89-100 or any future product candidate may be affected by a variety of factors, including the safety and efficacy of our
product candidates, investment in our clinical programs, manufacturing capability and competition with other products. As a result, we are unable to
determine the timing of initiation, duration and completion costs of our research and development efforts or when and to what extent we will generate
revenue from the commercialization and sale of BIO89-100 or any future product candidate.

Our future clinical development costs may vary significantly based on factors such as:

•

•

•

•

•

•

•

•

•

•

•

•

•

the cost and timing of manufacturing BIO89-100 and any future product candidates;

per-patient trial costs;

the number of trials required for approval;

the number of sites included in the trials;

the countries in which the trials are conducted;

the length of time required to enroll eligible patients;

the number of patients that participate in the trials;

the number of doses evaluated in the trials;

the drop-out or discontinuation rates of patients;

potential additional safety monitoring requested by regulatory agencies;

the duration of patient participation in the trials and follow-up;

the phase of development of BIO89-100 and any future product candidates; and

the efficacy and safety profile of BIO89-100 and any future product candidates.

General and Administrative Expenses

Our general and administrative expenses consist primarily of personnel costs, expenses for outside professional services, including legal, human
resource, audit and accounting services, consulting costs and allocated facilities costs. Personnel and related costs consist of salaries, benefits and share-
based compensation for personnel in executive, finance and other administrative functions. Facilities costs consist of rent and maintenance of facilities. We
expect our general and administrative expenses to increase for the foreseeable future as we increase the size of our administrative function to support the
growth of our business and support our continued research and development activities. We also anticipate increased expenses as a result of operating as a
public company, including increased expenses related to audit, legal, regulatory and tax-related services associated with maintaining compliance with
exchange listing and SEC requirements, director and officer insurance premiums and investor relations costs.

Other Expenses (Income), Net

Other expenses (income), net primarily consists of the revaluation of our convertible preferred stock liability.

Research and development expenses increased by $7.7 million, or 56%, to $21.4 million for the year ended December 31, 2019 from $13.7 million

during the period from January 18, 2018 (inception) to December 31, 2018. The increase was primarily due to an increase of $3.9 million in contract
manufacturing costs, an increase of $3.6 million in clinical development costs as we continue to advance our current clinical programs with our lead
product candidate, BIO89-100 and an increase of $2.9 million in pre-clinical costs. In addition, personnel-related costs, including share-based
compensation, increased by $2.7 million and other expenses increased by $0.6 million due to increased headcount and other costs as we ramped up our
operations. These increases were partially offset by a $6.0 million decrease due to an up-front license payment to Teva during the period from January 18,
2018 (inception) to December 31, 2018 and there were no such license payment expenses related to Teva during the year ended December 31, 2019.

General and Administrative Expenses

General and administrative expenses increased by $3.8 million, or 257%, to $5.3 million for the year ended December 31, 2019 from $1.5 million

during the period from January 18, 2018 (inception) to December 31, 2018. The increase was primarily due to an increase of $1.9 million in professional
and accounting consulting service fees incurred in connection with our preparation to become a public company, an increase of $1.6 million in personnel-
related costs, including share-based compensation, driven by an increase in headcount and an increase of $0.3 million in insurance related costs.

Other Expenses (Income), Net

Other expenses (income), net increased by $29.6 million to $30.6 million for the year ended December 31, 2019 from $1.0 million during the
period from January 18, 2018 (inception) to December 31, 2018. The increase in other expenses was primarily due to the revaluation of our convertible
preferred stock liability.

Liquidity and Capital Resources

To date, we have incurred significant net losses and negative cash flows from operations. As of December 31, 2019, we had available cash and cash

equivalents of $93.3 million and an accumulated deficit of $73.6 million. Prior to our IPO, we funded our operations from the issuance and sale of capital
stock. In connection with our IPO, we issued and sold an aggregate of 6,100,390 shares of common stock (inclusive of 795,703 shares of common stock
from the exercise of the option to purchase additional shares granted to the underwriters) at a price of $16.00 per share. We received proceeds of $87.7
million, net of underwriting discounts and commissions and estimated offering costs.

Our primary use of cash is to fund operating expenses, which consist primarily of research and development expenditures related to our lead

product candidate, BIO89-100. We plan to increase our research and development expenses substantially for the foreseeable future as we continue the
clinical development of our current and future product candidates. At this time, due to the inherently unpredictable nature of clinical development, we
cannot reasonably estimate the costs we will incur and the timelines that will be required to complete development, obtain marketing approval, and
commercialize our current product candidate or any future product candidates. For the same reasons, we are also unable to predict when, if ever, we will
generate revenue from product sales or our current or any future license agreements which we may enter into or whether, or when, if ever, we may achieve
profitability. Clinical and preclinical development timelines, the probability of success, and development costs can differ materially from expectations. In
addition, we cannot forecast the timing and amounts of milestone, royalty and other revenue from licensing activities, which future product candidates may
be subject to future collaborations, when such arrangements will be secured, if at all, and to what degree such arrangements would affect our development
plans and capital requirements.

Based on our research and development plans, we expect that our existing cash and cash equivalents will be sufficient to fund our operations into
the second half of 2021. However, our operating plans and other demands on our cash resources may change as a result of many factors, and we may seek
additional funds sooner than planned. There can be no assurance that we will be successful in acquiring additional funding at levels sufficient to fund our
operations or on terms favorable to us.

103

 
Our future funding requirements will depend on many factors, including the following:

•

•

•

•

•

•

•

•

•

the progress, timing, scope, results and costs of our clinical trials of BIO89-100 and preclinical studies or clinical trials of other potential
product candidates we may choose to pursue in the future, including the ability to enroll patients in a timely manner for our clinical trials;

the costs and timing of obtaining clinical and commercial supplies and validating the commercial manufacturing process for BIO89-100
and any other product candidates we may identify and develop;

the cost, timing and outcomes of regulatory approvals;

the timing and amount of any milestone, royalty or other payments we are required to make pursuant to current or any future collaboration
or license agreements;

costs of acquiring or in-licensing other product candidates and technologies;

the terms and timing of establishing and maintaining collaborations, licenses and other similar arrangements;

the costs associated with attracting, hiring and retaining additional qualified personnel as our business grows;

our efforts to enhance operational systems and hire additional personnel to satisfy our obligations as a public company, including enhanced
internal controls over financial reporting; and

the cost of preparing, filing, prosecuting, defending and enforcing any patent claims and other intellectual property rights.

We expect to continue to generate substantial operating losses for the foreseeable future as we expand our research and development activities. We
will continue to fund our operations primarily through utilization of our current financial resources and through additional raises of capital to advance our
current product candidate through clinical development, to develop, acquire or in-license other potential product candidates and to fund operations for the
foreseeable future. However, there is no assurance that such funding will be available to us or that it will be obtained on terms favorable to us or will
provide us with sufficient funds to meet our objectives. Any failure to raise capital as and when needed could have a negative impact on our financial
condition and on our ability to pursue our business plans and strategies.

To the extent that we raise additional capital through partnerships or licensing arrangements with third parties, we may have to relinquish valuable

rights to our product candidates, future revenue streams or research programs or to grant licenses on terms that may not be favorable to us. If we raise
additional capital through public or private equity offerings, the ownership interest of our then-existing stockholders will be diluted, and the terms of these
securities may include liquidation or other preferences that adversely affect our stockholders’ rights. If we raise additional capital through debt financing,
we may be subject to covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or
declaring dividends. If we are unable to obtain adequate financing when needed, we may have to delay, reduce the scope of or suspend one or more of our
clinical trials or preclinical studies, research and development programs or commercialization efforts or grant rights to develop and market our product
candidates even if we would otherwise prefer to develop and market such product candidates ourselves.

Net Cash Used in Operating Activities

During the year ended December 31, 2019, net cash used in operating activities was $25.5 million, which consisted of a net loss of $57.4 million,
partially offset by non-cash charges of $31.0 million and a net change of $0.9 million in our net operating assets and liabilities. The non-cash charges are
primarily comprised of the revaluation of our convertible preferred stock liability of $30.6 million and $0.4 million in share-based compensation. The
change in our operating assets and liabilities was primarily due to a $2.9 million increase in accounts payable and accrued expenses as we grew our
operations, partially offset by a $2.0 million increase in other current assets and other assets due to the timing of payments.

During the period from January 18, 2018 (inception) to December 31, 2018, net cash used in operating activities was $12.5 million, which
consisted of a net loss of $16.2 million, partially offset by non-cash charges of $1.1 million and a net change of $2.6 million in our net operating assets and
liabilities. The non-cash charges are primarily comprised of the revaluation of our convertible preferred stock liability of $1.0 million and $0.1 million in
share-based compensation. The change in our net operating assets and liabilities was primarily due to a $2.7 million increase in accounts payable and
accrued expenses as we grew our operations.

Net Cash Used in Investing Activities

During the year ended December 31, 2019 and the period from January 18, 2018 (inception) to December 31, 2018, net cash used in investing

activities consisted of purchases of fixed assets.

Net Cash Provided by Financing Activities

During the year ended December 31, 2019 net cash provided by financing activities was $107.7 million, which consisted of net proceeds of $87.7
million received from our initial public offering and net proceeds of $20.0 million received from the issuance and sale of our convertible preferred stock.

During the period from January 18 (inception) to December 31, 2018 net cash provided by financing activities was $23.8 million, which primarily

consisted of net proceeds of $23.7 million from the issuance and sale of our convertible preferred stock.

Critical Accounting Polices and Estimates

Our management’s discussion and analysis of our financial condition and results of operations is based on our consolidated financial statements,
which have been prepared in accordance with United States generally accepted accounting principles (“GAAP”). The preparation of these consolidated
financial statements requires us to make  estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent
assets and liabilities as of the date of the consolidated financial statements, as well as the reported expenses incurred during the reporting periods. Our
estimates are based on our historical experience and on various other factors that we believe are reasonable under the circumstances, the results of which
form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may
differ from these estimates under different assumptions or conditions. We believe that the accounting policies discussed below are critical to understanding
our historical and future performance, as these policies relate to the more significant areas involving management’s judgments and estimates.

While our significant accounting policies are described in the notes to our consolidated financial statements included elsewhere in this Annual

Report on Form 10-K, we believe that the following critical accounting policies are most important to understanding and evaluating our reported financial
results.

Accrued Research and Development Expenses

We record accrued expenses for estimated preclinical and clinical trial and research expenses related to the services performed but not yet invoiced

pursuant to contracts with research institutions, contract research organizations and clinical manufacturing organizations that conduct and manage
preclinical studies, and clinical trials, and research services on our behalf. Payments for these services are based on the terms of individual agreements and
payment timing may differ significantly from the period in which the services were performed. Our estimates are based on factors such as the work
completed, including the level of patient enrollment. We monitor patient enrollment levels and related activity to the extent reasonably possible and make
judgments and estimates in determining the accrued balance in each reporting period. Our estimates of accrued expenses are based on the facts and
circumstances known at the time. If we underestimate or overestimate the level of services performed or the costs of these services, our actual expenses
could differ from our estimates. As actual costs become known, we adjust our accrued expenses. To date, we have not experienced significant changes in
our estimates of preclinical studies and clinical trial accruals.

Convertible Preferred Stock Liability

The freestanding instruments related to the commitments by the Series A convertible preferred shareholders to purchase and by us to sell our Series

A convertible preferred shares in subsequent closings, contingent upon the achievement of certain developmental milestones and approval by the board of
directors, at a fixed price per share, were considered a liability (or an asset) measured at fair value as the shares underlying the rights contain liquidation
preferences upon certain “deemed liquidation events” that were not solely within the Company’s control and which were considered in-substance
contingent redemption features. The instruments were subject to revaluation at each balance sheet date until settlement or extinguishment, with revaluations
recognized as a component of either other expenses (income), net in the consolidated statements of operations and comprehensive loss, or additional paid-
in capital in the consolidated balance sheets.

Share-Based Compensation

We recognize compensation expense related to share-based awards granted to employees, directors, and non-employee service providers, including

stock options, based on the estimated fair value of the awards on the date of grant. We estimate the grant date fair value, and the resulting share-based
compensation, using the Black-Scholes option-pricing model. The grant date fair value of the share-based awards, which have graded vesting, is recognized
using the straight-line method over the requisite service period of each award, which is generally the vesting period of the respective awards. We recognize
forfeitures as they occur.

106

 
We use the Black-Scholes option-pricing model to estimate the fair value of stock option awards that requires the use of subjective assumptions to

determine the fair value of share-based awards. These assumptions include:

•

•

•

•

Expected volatility—Since we have limited trading history for our common stock due to our short trading history, the expected volatility
was estimated based on the average volatility for comparable publicly traded biotechnology companies during the equivalent period of the
calculated expected term of the options granted. The comparable companies were chosen based on their similar size, stage in the life cycle
or area of specialty.

Risk-free interest rate—The risk-free interest rate is based on the U.S. Treasury zero coupon bonds in effect at the time of grant for periods
corresponding with the expected term of the option.

Expected term—The expected term of options granted to employees and directors is determined using the “simplified” method. Under this
approach, the expected term is presumed to be the mid-point between the weighted-average vesting term and the contractual term of the
option. The simplified method makes the assumption that the employee will exercise share options evenly over the period when the share
options are vested and ending on the date when the share options would expire. The expected option term for options granted to non-
employees is based on the contractual term.

Expected dividend—We have never paid dividends on our shares of common stock and have no plans to pay dividends on our shares of
common stock. Therefore, we used an expected dividend of zero.

We will continue to use judgment in evaluating the expected volatility and expected term utilized for our share-based compensation calculations on

a prospective basis.

Assumptions we used in applying the Black-Scholes option-pricing model to determine the estimated fair value of our stock options granted

involve inherent uncertainties and the application of significant judgment. As a result, if factors or expected outcomes change and we use significantly
different assumptions or estimates, our equity-based compensation could be materially different.

Prior to our IPO, given the absence of a public trading market for our shares of common stock, our board of directors exercised their judgment and

considered a number of objective and subjective factors to determine the best estimate of the fair value of our shares of common stock, including timely
valuations of our shares of common stock prepared by an unrelated third-party valuation firm, important developments in our operations, sales of
convertible preferred shares, actual operating results and financial performance, the conditions in the biotechnology industry and the economy in general,
the stock price performance and volatility of comparable public companies, and the lack of liquidity of our shares of common stock, among other factors.
Following our IPO, the closing price per share of our common stock as reported on The Nasdaq Global Market on the date of grant is used to determine the
determine the fair value of each share of common stock. Options granted shall be exercisable at a price per share not less than the estimated per share fair
value of shares of common stock underlying those options on the date of grant.

Recent Accounting Pronouncements

See Note 2 to our consolidated financial statements appearing under Part II, Item 8 for more information about recent accounting pronouncements,

the timing of their adoption, and our assessment, to the extent we have made one yet, of their potential impact on our financial condition of results of
operations.

JOBS Act Accounting Election

We are an emerging growth company, as defined in the JOBS Act. Under the JOBS Act, emerging growth companies can delay adopting new or

revised accounting standards issued subsequent to the enactment of the JOBS Act until such time as those standards apply to private companies.

We have elected to use this extended transition period to enable us to comply with new or revised accounting standards that have different effective

dates for public and private companies until the earlier of the date we (i) are no longer an emerging growth company or (ii) affirmatively and irrevocably
opt out of the extended transition period provided in the JOBS Act. As a result, our consolidated financial statements and our interim consolidated financial
statements may not be comparable to companies that comply with new or revised accounting pronouncements.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk.

We are a smaller reporting company, as defined by Rule 12b-2 under the Securities and Exchange Act of 1934 and in Item 10(f)(1) of Regulation

Report of Independent Registered Public Accounting Firm

To the stockholders and the Board of Directors of 89bio, Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheet of 89bio, Inc. and subsidiaries (the “Company”) as of December 31, 2019, the related
consolidated statements of operations and comprehensive loss, convertible preferred stock and stockholders’ equity (deficit), and cash flows, for the year
then ended, 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 the year ended
December 31, 2019, in conformity with accounting principles generally accepted in the United States of America.

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 Public Company Accounting Oversight Board (United States) (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. The Company is not required to have, nor
were we engaged to perform, an audit of its internal control over financial reporting. As part of our audit, we are required to obtain an understanding of
internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over
financial reporting. Accordingly, we express no such opinion.

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.

Report of Independent Registered Public Accounting Firm

To the stockholders and the Board of Directors of 89bio, Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheet of 89bio, Inc. and subsidiaries (operating as 89Bio Ltd. prior to the reorganization described
in Note 1) (the “Company”) as of December 31, 2018 and the related consolidated statements of operations and comprehensive loss, convertible preferred
shares and shareholders’ deficit and cash flows for the period from January 18, 2018 (inception) to December 31, 2018, 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, 2018, and the results of its operations and its cash flow for the period from January 18, 2018 (inception) to December 31,
2018, in conformity with accounting principles generally accepted in the United States of America.

Going Concern

The 2018 financial statements were prepared assuming that the Company will continue as a going concern. As of the date of issuance of the Company’s
2018 financial statements, the Company’s lack of revenues and substantial operating losses raised substantial doubt about its ability to continue as a going
concern. The 2018 financial statements did not include any adjustments that might result from the outcome of these uncertainties.

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 Public Company Accounting Oversight Board (United States)
(“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. The Company is not required to have, nor
were we engaged to perform, an audit of its internal control over financial reporting. As part of our audit, we are required to obtain an understanding of
internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over
financial reporting. Accordingly, we express no such opinion.

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.

Notes to Consolidated Financial Statements

1. Organization and Basis of Presentation

Description of Business

89bio, Inc. (“89bio” or the “Company”) is a clinical-stage biopharmaceutical company focused on the development and commercialization of

innovative therapies for the treatment of liver and cardio-metabolic diseases. The Company’s lead product candidate, BIO89-100, a specifically engineered
glycoPEGylated analog of fibroblast growth factor 21, is currently being developed for the treatment of nonalcoholic steatohepatitis.

89Bio Ltd. was incorporated in Israel in January 2018 and has two wholly owned subsidiaries: 89bio Management, Inc., located in San Francisco,
California and UAB 89bio Lithuania, located in Vilnius, Lithuania. 89bio, Inc. was formed as a Delaware corporation on June 28, 2019, for the purpose of
completing an initial public offering (“IPO”) and related transactions in order to carry on the business of 89Bio Ltd.

The Company completed an internal reorganization transaction in September 2019, pursuant to which 89Bio Ltd. became a wholly owned

subsidiary of 89bio, Inc. (the “Reorganization”). As part of the Reorganization, all of the equity holders of 89Bio Ltd. Exchanged 100% of the equity of
89Bio Ltd. for 100% of the equity of 89bio, Inc.

The Reorganization was considered a transaction between entities under common control. As a result, the accompanying consolidated financial

statements have been retrospectively adjusted to reflect the Reorganization.

Initial Public Offering

On November 13, 2019, 89bio, Inc. completed the IPO, pursuant to which it issued and sold an aggregate of 6,100,390 shares of common stock

(inclusive of 795,703 shares pursuant to the underwriters’ option to purchase additional shares) at the IPO price of $16.00 per share, resulting in net
proceeds of $87.7 million after deducting underwriting discounts and commissions of $6.8 million and other offering expenses of $3.1 million. Upon the
closing of the IPO, the Company’s outstanding convertible preferred stock automatically converted into 7,077,366 shares of common stock of 89bio, Inc.
based on a proportional adjustment to the conversion ratio of the convertible preferred stock on a 1-for-6.217 basis.

Reverse Stock Split

On October 24, 2019, 89bio, Inc.’s board of directors approved an amendment to the amended and restated certificate of incorporation of 89bio,

Inc. to effect a 1 for 6.217 reverse split (“Reverse Split”) of shares of the common stock of 89bio, Inc. and a proportional adjustment to the conversion ratio
of the convertible preferred stock, which was effected on October 25, 2019. The par value and authorized shares of common stock, and the par value,
authorized and outstanding shares of the convertible preferred stock were not adjusted as a result of the Reverse Split. All of the share and per share
information for 89bio, Inc. included in the accompanying consolidated financial statements has been adjusted to reflect the Reverse Split.

Liquidity

The accompanying consolidated financial statements have been prepared assuming the Company will continue as a going concern, which
contemplates the realization of assets and liquidation of liabilities in the normal course of business. To date, the Company has not generated revenues from
its activities and has incurred substantial operating losses. Management expects the Company to continue to generate substantial operating losses for the
foreseeable future until it completes development of its products and seeks regulatory approvals to market such products. The Company had cash and cash
equivalents of $93.3 million as of December 31, 2019. Management expects to continue to fund its operations primarily through utilization of its current
financial resources and through additional raises of capital.

116

 
89bio, Inc.
Notes to Consolidated Financial Statements

The Company intends to raise such capital through the issuance of additional equity financing and/or debt financing. However, if such financing is
not available at adequate levels, the Company will need to reevaluate its operating plan and may be required to delay the development of its products. The
Company expects that its cash and cash equivalents as of December 31, 2019 will be sufficient to fund operating expenses and capital expenditure
requirements for a period of at least one year from the date these audited consolidated financial statements are filed with the Securities and Exchange
Commission (“SEC”).

2. Summary of Significant Accounting Policies

Basis of Presentation

The consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States (“U.S.

GAAP”).

Principles of Consolidation

The accompanying consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany

balances and transactions have been eliminated in consolidation.

Foreign Currencies

Certain transactions during the period from January 18, 2018 (inception) to December 31, 2018 and the year ended December 31, 2019 were

denominated in the Euro or Israeli New Shekel. Gains and losses from foreign currency transactions were not material for all periods presented and are
reflected in the consolidated statement of operations and comprehensive loss as a component of other expenses (income), net. The financial statements of
UAB 89bio Lithuania use the Euro as the functional currency. The re-measurement from Euros to U.S. dollars results in translation gain and loss
adjustments, which were not material for all periods presented. Accordingly, the Company has not presented translation gain and loss adjustments
separately as a component of comprehensive loss.

Use of Estimates

The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the consolidated financial statements
and the reported amounts of expenses during the reporting period. Significant estimates and assumptions made in the accompanying consolidated financial
statements include but are not limited to the fair value of stock options, the convertible preferred stock liability and certain accruals. The Company
evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors and adjusts those estimates and assumptions when
facts and circumstances dictate. Actual results could differ from those estimates.

Fair Value Measurements

Financial assets and liabilities are recorded at fair value on a recurring basis in the balance sheets. The carrying values of Company’s financial

assets and liabilities, including cash and cash equivalents, restricted cash, prepaid and other current assets, accounts payable, and accrued expenses
approximate to their fair value due to the short-term maturity of these instruments. Fair value is defined as the price that would be received to sell an asset
or paid to transfer a liability (an exit price) in an orderly transaction between market participants at the reporting date. Assets and liabilities recorded at fair
value are categorized based upon the level of judgment associated with the inputs used to measure their fair value. Hierarchical levels are directly related to
the amount of subjectivity with the inputs to the valuation of these assets or liabilities as follows:

Level 1—Observable inputs such as unadjusted, quoted prices in active markets for identical assets or liabilities at the measurement date;

Level 2—Inputs (other than quoted prices included in Level 1) are either directly or indirectly observable inputs for similar assets or liabilities.
These include quoted prices for identical or similar assets or liabilities in active markets and quoted prices for identical or similar assets or
liabilities in markets that are not active;

Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

Notes to Consolidated Financial Statements

Convertible Preferred Stock Liability

The freestanding instruments related to the commitment by the Series A convertible preferred stockholders to purchase and by the Company to sell

its Series A convertible preferred stock in subsequent closings, contingent upon the achievement of certain developmental milestones and approval by the
board of directors, at a fixed price per stock, were considered a liability (or an asset), measured at fair value as the shares underlying the rights contained
liquidation preferences upon certain “deemed liquidation events” that were not solely within the Company’s control and which were considered in-
substance contingent redemption features (refer to Note 7 for further discussion on the redemption rights of the convertible preferred stock). The
instruments were subject to revaluation at each balance sheet date until settlement or extinguishment, with revaluations recognized as either a component of
other expenses (income), net in the consolidated statements of operations and comprehensive loss, or additional paid-in capital in the consolidated balance
sheets.

Cash and Cash Equivalents and Restricted Cash

The Company considers all highly liquid investments purchased with original maturities of three months or less from the purchase date to be cash

equivalents. Cash equivalents consist primarily of amounts invested in money market accounts and are stated at fair value. Restricted cash consists of a
money market account that serves as collateral for the Company’s operating lease agreement for its facility in Israel.

Concentrations of Credit Risk

Financial instruments that potentially subject the Company to a concentration of credit risk consist primarily of cash and cash equivalents. Bank

deposits are held by accredited financial institutions and these deposits may at times be in excess of insured limits. The Company limits its credit risk
associated with cash and cash equivalents by placing them with financial institutions that it believes are of high quality. The Company has not experienced
any losses on its deposits of cash or cash equivalents.

Other Risks and Uncertainties

The Company’s future results of operations involve a number of other risks and uncertainties. Factors that could affect the Company’s future

operating results and cause actual results to vary materially from expectations include, but are not limited to, the Company’s early stages of clinical drug
development; the Company’s ability to advance product candidates into, and successfully complete, clinical trials on the timelines it projects; the
Company’s ability to adequately demonstrate sufficient safety and efficacy of its product candidates; the Company’s ability to enroll patients in its ongoing
and future clinical trials; the Company’s ability to successfully manufacture and supply its product candidates for clinical trials; the Company’s ability to
obtain additional capital to finance its operations; uncertainties related to the projections of the size of patient populations suffering from the diseases the
Company is targeting; the Company’s ability to obtain, maintain, and protect its intellectual property rights; developments relating to the Company’s
competitors and its industry, including competing product candidates and therapies; general economic and market conditions; and other risks and
uncertainties.

The Company’s product candidates will require approvals from the U.S. Food and Drug Administration and comparable foreign regulatory
agencies prior to commercial sales in their respective jurisdictions. There can be no assurance that any product candidates will receive the necessary
approvals. If the Company was denied approval, approval was delayed or the Company was unable to maintain approval for any product candidate, it could
have a materially adverse impact on the Company.

Property and Equipment, Net

Property and equipment are stated at cost, less accumulated depreciation. Depreciation is calculated on a straight-line basis over the estimated
useful lives of the related assets, generally ranging from three to seven years. Leasehold improvements are amortized on a straight-line basis over the
shorter of the assets’ estimated useful life or the remaining term of the lease. Upon retirement or sale of the assets, the cost and related accumulated
depreciation and amortization are removed from the balance sheet and the resulting gains or losses are recorded to the statements of operations.
Maintenance and repair costs are expensed as incurred.

Notes to Consolidated Financial Statements

Impairment of Long-Lived Assets

The Company periodically evaluates its long-lived assets, including property and equipment, for impairment whenever events or changes in
business circumstances indicate that the carrying amount of the assets or group of assets may not be fully recoverable. If indicators of impairment exist and
the undiscounted future cash flows that the assets are expected to generate are less than the carrying value of the assets, the Company reduces the carrying
amount of the assets through an impairment charge, to their estimated fair values based on a discounted cash flow approach or, when available and
appropriate, to comparable market values. There were no such indicators for the periods presented.

Leases

The Company leases its office facilities under a non-cancelable operating lease agreement and recognizes related rent expense on a straight-line

basis over the term of the lease.

Research and Development Expenses and Accrued Research and Development Expenses

Research and development expenses consist primarily of costs incurred for the development of the Company’s lead product candidate, BIO89-100.
Research and development expenses consist primarily of external costs related to acquiring and licensing patents and intellectual properties, preclinical and
clinical development and related supplies, and personnel costs. Personnel costs consist of salaries, employee benefits and  share-based compensation for
individuals involved in research and development efforts. The Company estimates preclinical and clinical study and research expenses based on the
services performed, pursuant to contracts with research institutions that conduct and manage preclinical and clinical studies and research services on its
behalf. The Company records the costs of research and development activities based upon the estimated amount of services provided but not yet invoiced
and includes these costs in accrued liabilities in the consolidated balance sheets. These costs are a component of the Company’s research and development
expenses.

The Company accrues for these costs based on factors such as estimates of the work completed and in accordance with agreements established with

its third-party service providers under the service agreements. The Company makes significant judgments and estimates in determining the accrued
liabilities balance. As actual costs become known, the Company adjusts its accrued expenses. The Company has not experienced any material differences
between accrued costs and actual costs incurred. However, the status and timing of actual services performed may vary from the Company’s estimates,
resulting in adjustments to expense in future periods. Changes in these estimates that result in material changes to the Company’s accruals could materially
affect the Company’s results of operations. Payments associated with licensing agreements to acquire licenses to develop, use, manufacture and
commercialize products that have not reached technological feasibility and do not have alternate commercial use are expensed as incurred. Contingent
milestone payments, if any, are expensed when the milestone results are probable and estimable, which is generally upon achievement of the milestone.

Share-Based Compensation

The Company measures its share-based payment awards made to employees, directors, and non-employee service providers based on estimated

fair values and recognizes compensation over the requisite service period.

The Company estimates the fair value of share-based payment awards on the date of grant using a Black-Scholes option pricing model. The value

of the portion of the share-based payment award that is ultimately expected to vest is recognized as an expense over the requisite service period in the
consolidated statements of operations and comprehensive loss.

The Company recognizes compensation for the value of share-based payment awards, which have graded vesting, using the straight-line method

over the requisite service period of each award. The Company accounts for forfeitures as they occur.

119

 
89bio, Inc.
Notes to Consolidated Financial Statements

The Black-Scholes option pricing model requires a number of assumptions, of which the most significant are expected volatility, expected option

term (the time from the grant date until the options are exercised or expire), risk-free rate, and expected divided rate. Expected volatility is estimated based
on volatility of comparable publicly traded biotechnology companies. The Company has historically not paid dividends and has no foreseeable plans to pay
dividends, therefore the Company uses an expected dividend yield of 0%. The risk-free interest rate is based on the yield from U.S. Treasury zero-coupon
bonds with an equivalent expected term. The expected option term is calculated for options granted to employees and directors using the “simplified”
method. Under this approach, the expected term is presumed to be the midpoint between the weighted average vesting term and the contractual term of the
option. The simplified method makes the assumption that the employee will exercise share options evenly over the period when the share options are
vested and ending on the date when the share options expire. The expected option term for options granted to non-employees is based on the contractual
term. Changes in the determination of each of the inputs can affect the fair value of the share options granted and the results of operations of the Company.

Deferred Offering Costs

Deferred offering costs, consisting of legal, accounting, and filing fees directly relating to the IPO, were capitalized and upon completion of the

IPO, approximately $3.1 million of deferred offering costs were offset against the IPO proceeds in additional paid-in capital. For the year ended December
31, 2018, the Company did not incur any deferred offering costs.

Income Taxes

Income taxes are accounted for under the asset and liability method. Under this method, deferred tax assets and liabilities are recognized for the
future tax consequences attributable to differences between the consolidated financial statements carrying amounts of existing assets and liabilities and
their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates applied to
taxable income in the years in which those temporary differences are expected to be realized. The effect on deferred tax assets and liabilities of a change in
tax rates is recognized as income or loss in the period that includes the enactment date. A valuation allowance is established when necessary to reduce
deferred tax assets to the amount expected to be realized. Interest and penalties related to unrecognized tax benefits are included within the provision of
income tax. To date, there have been no unrecognized tax benefits balances.

Basic and Diluted Net Loss per Share

Basic loss per share is computed by dividing the net loss by the weighted average number of common stock outstanding during the period. Diluted

loss per share is computed by dividing the net loss by the weighted average number of common stock outstanding together with the number of additional
common stock that would have been outstanding if all potentially dilutive common stock had been issued. Since the Company was in a loss position for the
periods presented, basic net loss per share is the same as diluted net loss per share since the effects of potentially dilutive securities are antidilutive.

Comprehensive Loss

The Company’s comprehensive loss is comprised of changes related to translation gain and loss adjustments, which were not material for all

periods presented. Accordingly, the Company has not presented comprehensive loss separately from net loss on the consolidated statements of operations
and comprehensive loss.

Segment Reporting

The Company has one operating segment. The Company’s chief operating decision maker, its Chief Executive Officer, manages the Company’s

operations on a consolidated basis for the purposes of allocating resources and evaluating financial performance.

Recently Adopted Accounting Standards

In May 2014, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) 2014-09—Revenue from

contracts with customers, to achieve a consistent application of revenue recognition, resulting in a single revenue model to be applied by reporting
companies under U.S. GAAP. Under the new model, recognition of revenue occurs when a customer obtains control of the promised goods or services in
an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In addition, the standard requires
that reporting companies disclose the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. The
standard is effective for public entities for fiscal years beginning after December 15, 2017 and is effective for nonpublic entities for fiscal years beginning
after December 15, 2018. The standard is required to be applied retrospectively to each prior reporting period presented or retrospectively with the
cumulative effect of initially applying it recognized at the date of initial application. The Company adopted this standard on January 1, 2019, and as the
Company has no revenues to date, the adoption of the standard did not have any impact on its consolidated financial statements.

In June 2018, the FASB issued ASU No. 2018-07 Compensation—Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based
Payment Accounting, which is intended to reduce the cost and complexity and to improve financial reporting for nonemployee share based payment. The
standard expands the scope of Topic 718, (which currently only includes share-based payments to employees) to include share-based payments issued to
nonemployees for goods or services. Consequently, the accounting for share-based payments to nonemployees and employees will be substantially aligned.
The standard is effective for public entities for fiscal years beginning after December 15, 2019 and nonpublic entities for fiscal years beginning after
December 15, 2020. Early adoption is permitted but no earlier than a company’s adoption date of Topic 606. The Company early adopted this standard on
January 1, 2019, and the impact of its adoption on the Company’s consolidated financial statements was not material.

Recent Accounting Pronouncements

In February 2016, the FASB issued ASU 2016-02—Leases, requiring the recognition of lease assets and liabilities on the balance sheet. The

standard: (a) clarifies the definition of a lease; (b) requires a dual approach to lease classification similar to current lease classifications; and (c) causes
lessees to recognize leases on the balance sheet as a lease liability with a corresponding right-of-use asset for leases with a lease-term of more than twelve
months. The standard is effective for public entities for fiscal years beginning after December 15, 2018 and for nonpublic entities for fiscal years beginning
after December 15, 2020. The Company is currently evaluating the impact of this standard on its consolidated financial statements and related disclosures.

In August 2018, the FASB issued ASU No. 2018-13, Disclosure Framework – Changes to the Disclosure Requirements for Fair Value

Measurement, which amends ASC 820, Fair Value Measurement. This ASU modifies the disclosure requirements for fair value measurements by
removing, modifying, or adding certain disclosures. The standard is effective for public and nonpublic entities for fiscal years beginning after December
15, 2019, with early adoption permitted for the removed disclosures and delayed adoption until fiscal years beginning after December 15, 2019 permitted
for the new disclosures. The removed and modified disclosures will be adopted on a retrospective basis and the new disclosures will be adopted on a
prospective basis. The Company is currently evaluating the impact of this standard on its consolidated financial statements and related disclosures.

In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes (“ASU 2019-12”),
which is intended to simplify the accounting for income taxes. ASU 2019-12 removes certain exceptions to the general principles in Topic 740 and also
clarifies and amends existing guidance to improve consistent application. The new standard is effective for public entities for fiscal years beginning after
December 15, 2020 and for nonpublic entities for fiscal years beginning after December 15, 2021. The Company is currently evaluating the impact of this
standard on its consolidated financial statements and related disclosures.

The Company’s convertible preferred stock liability resulted from the initial sale of Series A convertible preferred stock where the investors’

committed to purchase additional shares of Series A convertible preferred stock in subsequent closings, contingent upon the achievement by the Company
of certain development milestones and approval by the board of directors. The investors’ commitment to purchase and the Company’s commitment to sell
shares of Series A convertible preferred stock represented a freestanding instrument accounted for at fair value and re-measured at each reporting date. The
Company estimated the fair value of this commitment using the Black Scholes option pricing model using the following assumptions:

Exercise price
Expected term (years)
Expected volatility

Rent expense was $159,000 for year ended December 31, 2019 and $39,000 during the period from January 18, 2018 (inception) to December 31,

2018. The Company has security deposit balances of $95,000, which are included in restricted cash and other assets in the consolidated balance sheets as of
December 31, 2019. The security deposit balance of $23,000 was included in restricted cash in the consolidated balance sheets as of December 31, 2018.

Asset Transfer and License Agreement with Teva Pharmaceutical Industries Ltd

In April 2018, the Company concurrently entered into two Asset Transfer and License Agreements (the “Teva Agreements”) with Teva

Pharmaceutical Industries Ltd (“Teva”) under which it acquired certain patents and intellectual property relating to two programs: (1) Teva’s
glycoPEGylated FGF21 program, including the compound TEV-47948 (BIO89-100), a glycoPEGylated long-acting FGF21 and (2) Teva’s development
program of small molecule inhibitors of Fatty Acid Synthase. Pursuant to the Teva Agreements, the Company paid Teva an initial nonrefundable upfront
payment of $6.0 million and the Company could be obligated to pay Teva up to $67.5 million under each program, for a total of $135.0 million, upon the
achievement of certain clinical development and commercial milestones. In addition, the Company is obligated to pay Teva tiered royalties at percentages
in the low-to-mid single-digits on worldwide net sales on all products containing the Teva compounds.

The Teva Agreements can be terminated (i) by the Company without cause, after the first anniversary of the effective date, upon 120 days’ written
notice to Teva, (ii) by either party, if the other party materially breaches any of its obligations under the Agreements and fails to cure such breach within 60
days after receiving notice thereof, or (iii) by either party, if a bankruptcy petition is filed against the other party and is not dismissed within 60 days. In
addition, Teva can also terminate the agreement related to the Company’s glycoPEGylated FGF21 program in the event the Company, or any of its affiliates
or sublicensees, challenges any of the Teva patents licensed to the Company, and the challenge is not withdrawn within 30 days of written notice from
Teva.

The Company accounted for the acquisition of technology as an asset acquisition because it did not meet the definition of a business. The Company

recorded the total consideration transferred to Teva as research and development expense in the consolidated statements of operations and comprehensive
loss because the acquired technology represented in-process research and development and had no alternative future use. During the period from January
18, 2018 (inception) to December 31, 2018, the Company recognized an up-front license payment of $6.0 million in research and development expenses
under the Teva Agreements in its consolidated statements of operations and there were no such license payment expenses related to the Teva Agreements
during the year ended December 31, 2019.

6. Convertible Note

In March 2018, the Company entered into a Convertible Loan Agreement (the “Convertible Note”) with a principal amount of $100,000 and a
fixed interest rate of 8% per annum. The Convertible Note was automatically convertible into the Company’s next equity financing, or upon an earlier
event of default. In April 2018, the entire amount outstanding converted into 100,000 shares of Series A convertible preferred stock upon the initial closing
of the Series A financing.

7. Convertible Preferred Stock

In April 2018, the Company entered into the Series A Share Purchase Agreement (the “ Series A SPA”), pursuant to which the investors committed

to invest an aggregate amount of up to $60.0 million for the issuance of shares of Series A convertible preferred stock at a price of $1.00 per share.

The initial closing occurred on April 16, 2018, and the Company issued 14,900,000 shares of Series A convertible preferred stock at a price per

share of $1.00 for net cash proceeds of $14.7 million. The investors also committed to purchase 15,000,000 and 30,000,000 shares of Series A convertible
preferred stock at a price of $1.00 per share in second and third closings, respectively, contingent upon the achievement by the Company of certain
development milestones and approval by the board of directors.

89bio, Inc.
Notes to Consolidated Financial Statements

The investors’ commitment to purchase and the Company’s commitment to sell shares of Series A convertible preferred stock represent a
freestanding instrument accounted for at fair value and re-measured at each reporting date. The Company estimates the fair value of this commitment using
the Black-Scholes option pricing model. On the date of the initial closing, the Company recorded the commitments associated with the second and third
closings of the Series A convertible preferred stock at a net value of $638,000. For the year ended December 31, 2019 and for the period from January 18,
2018 (inception) to December 31, 2018, the Company recorded an expense of $30.6 million and $1.0 million, respectively, for the revaluation of the
convertible preferred stock liability, within other expenses (income), net in the consolidated statements of operations and comprehensive loss.

In December 2018, the Series A convertible preferred stockholders partially accelerated the second closing and the Company issued 9,000,000

shares of Series A convertible preferred stock at a price of $1.00 per share and received net proceeds of $9.0 million.

In June 2019, the Company and the Series A convertible preferred stockholders agreed to issue the remaining 6,000,000 shares of Series A
convertible preferred stock at a price of $1.00 per share related to the second closing, and to partially accelerate 14,000,000 shares of Series A convertible
preferred stock at a price of $1.00 per share related to the third closing. The shares were issued and the aggregate net proceeds of $20.0 million were
received in June and July 2019.

In September 2019, the Company completed an internal reorganization transaction pursuant to which 89Bio Ltd. became a wholly owned
subsidiary of 89bio, Inc. As part of the Reorganization, all outstanding convertible preferred shares of 89Bio Ltd. were exchanged into shares of convertible
preferred stock of 89bio, Inc.

On October 25, 2019, the Company and the Series A preferred stockholders amended the Series A SPA, and the parties agreed that the Series A

SPA would terminate upon consummation of the Company’s IPO.

Upon the completion of the Company’s IPO on November 13, 2019, the remaining 16,000,000 shares of convertible preferred stock that were

previously issuable under the third closing were no longer issuable. Accordingly, the preferred stock liability was extinguished and because the transaction
occurred between related parties, the resulting $25.6 million was accounted for as a capital contribution by the preferred stockholders. 

Additionally, immediately prior to the completion of the Company’s IPO, all outstanding shares of convertible preferred stock automatically

converted into 7,077,366 shares of common stock and the related carrying value was reclassified to common stock and additional paid-in capital.
Accordingly, there were no shares of convertible preferred stock outstanding as of December 31, 2019.  

Convertible preferred stock as of December 31, 2018 consisted of the following:

The Company’s certificate of incorporation did not provide redemption rights to the holders of the Series A convertible preferred stock. In the

event of a liquidation event, all the funds and assets of the Company available for distribution among all the stockholders would be distributed in the
following order of preference: (a) the holders of the Series A convertible preferred stock would be entitled to receive an amount per share equal to $1.00
per each Series A convertible preferred stock (less the amount of distributions actually received in any prior liquidation event, plus all declared but unpaid
dividends) and (b) the remaining assets of the Company available for distribution to stockholders would be distributed among the holders of common stock
and to the holders of the Series A convertible preferred stock on an as-converted and pro rata basis.

Notes to Consolidated Financial Statements

Although the convertible preferred stock was not redeemable, in the event of certain “deemed liquidation events” that were not solely within the

Company’s control (including merger, acquisition, or sale of all or substantially all of the Company’s assets), the holders of the convertible preferred stock
would be entitled to preference amounts paid before distribution to other stockholders and hence effectively redeeming the preference amount. As of
December 31, 2018, the convertible preferred stock was classified outside of stockholders’ equity (deficit) as a result of these in-substance contingent
redemption rights and the Company did not adjust the carrying values of the convertible preferred stock to the deemed liquidation values of such shares
since a liquidation event was not probable of occurring.

8. Common Stock

The Company is authorized to issue a total of 100,000,000 shares of common stock with a par value of $0.001 per share, 13,788,982 of which were

issued and outstanding as of December 31, 2019.

Equity Incentive Plans

In 2018, the Company’s board of directors adopted the 89Bio Ltd. 2018 Equity Incentive Plan (the “2018 Plan”). In connection with the
Reorganization, in September 2019, the Company’s board of directors approved the 2019 Equity Incentive Plan (the “2019 Plan”), which became effective
on September 17, 2019. From and after the effective date of the 2019 Plan, the Company will no longer be making any future awards under the 2018 Plan.

The Company initially reserved 2,844,193 shares of common stock for issuance under the 2019 Plan. In addition, the number of shares of common

stock reserved for issuance under the 2019 Plan will automatically increase on the first day of January for a period of up to ten years, commencing on
January 1, 2020, in an amount equal to 4% of the total number of shares of the Company’s capital stock outstanding on the immediately preceding
December 31, or a lesser number of shares determined by the Company’s board of directors. As of December 31, 2019, there were 1,523,950 shares of
common stock available for issuance as future option grants under the 2019 Plan.

The Board determines the period over which options become exercisable and options generally vest over a four-year period, with 25% of options
vesting on the first anniversary of employment, and thereafter, the remaining options vesting quarterly, over the following 36-month period. The options
will expire within ten years from the date of grant. The exercise price of awards granted will not be less than the estimated fair value of the shares on the
date of grant.

Employees Share Purchase Plan (ESPP)

In October 2019, the Company adopted the 2019 Employee Stock Purchase Plan (“ESPP”), which became effective following the date of the IPO.

The Company initially reserved 225,188 shares of common stock for purchase under the ESPP. The number of shares of common stock reserved for
issuance under the 2019 ESPP will automatically increase on the first day of January for a period of up to ten years, in an amount equal to 1% of the total
number of shares of the Company’s common stock outstanding on the immediately preceding December 31, or a lesser number of shares determined by the
Company’s board of directors. Purchases will be accomplished through the participation of discrete offering periods. Each offering will be no more than 27
months long. For each offering period, ESPP participants will purchase shares of common stock at a price per share equal to 85% of the lesser of the fair
market value of the Company’s common stock on (1) the first trading day of the applicable offering period or (2) the last trading day of each purchase
period the applicable offering period.

reporting purposes and the amounts used for income tax purposes. Significant components of the Company’s deferred tax assets are as follows (in

As of December 31, 2019 and 2018, the Company recorded a valuation allowance of $10.0 million and $3.5 million, respectively, in respect of

deferred tax assets resulting from tax loss carryforwards and other temporary differences. Realization of deferred tax assets is dependent upon future
earnings, if any, the time and amount of which are uncertain. As the Company  is still in its development stage and has not yet generated revenues, it is
more likely than not that sufficient taxable income will not be available for the tax losses to be utilized in the future. Therefore, a valuation allowance was
recorded to reduce the deferred tax assets to their recoverable amounts. The valuation allowance increased by $6.5 million in 2019, which primarily relates
to significant taxable losses. It also includes a recapture of the valuation allowance against the Company’s deferred tax assets in the United States due to the
reorganization that occurred in 2019, which increased the valuation allowance by $20,000.

Available Carryforward Tax Losses and Credits

As of December 31, 2019, the Company has an accumulated tax loss carryforward of approximately $9.1 million and $23.8 million for U.S. and

Israeli tax purposes, respectively. For the period from January 18, 2018 (inception) to December 31, 2018, the Company had an accumulated tax loss
carryforward of approximately $6.7 million for Israeli tax purposes. Federal net operating losses generated after 2017 can be carried forward indefinitely
but utilization will be limited to 80% of taxable income in the period that net operating losses are being utilized. Carryforward tax losses in Israel have no
expiration date.

As of December 31, 2019, the Company has state research and development credit carryforwards of approximately $156,000, which will

carryforward indefinitely.

Utilization of the U.S. federal and state net operating losses and credit carryforwards may be subject to an annual limitation provided for in Section

382 of the Internal Revenue Code and similar state codes. Any annual limitation could result in a deferral of the utilization of the net operating loss and
credit carryforwards.

Unrecognized Tax Benefits

During the year ended December 31, 2019, the amount of gross unrecognized tax benefits increased by $39,000 from a balance at the beginning of
the year of $0. If the total amount of unrecognized tax benefits was recognized, it would not have an impact to the effective tax rate as it would be offset by
the reversal of related deferred tax assets which are subject to a full valuation allowance.

The Company recognizes interest and penalties related to uncertain tax positions as part of the income tax provision. As of December 31, 2019 and

2018, such interest and penalties have not been material.

The Company is subject to taxation in the United States, California and several foreign jurisdictions. To date, the Company has not been subject to

any federal or state income tax audits. As of December 31, 2019, all tax years remain open to examination.

Notes to Consolidated Financial Statements

12. Related Party Transactions

The Company incurred $170,000 and $147,000 in professional consulting services expense related to certain members of the board of directors for

the year ended December 31, 2019 and for the period from January 18, 2018 (inception) to December 31, 2018, respectively, which were recorded within
research and development expenses on the Company’s consolidated statements of operations and comprehensive loss. The related party liability balance
was $11,000 and $23,000 as of December 31, 2019 and 2018, respectively, which was recorded within accounts payable and accrued expenses on the
Company’s consolidated balance sheets.

The Company and the Series A preferred stockholders amended the Series A SPA on October 25, 2019, and the parties agreed that the Series A

SPA would terminate upon consummation of the Company’s IPO. Upon the completion of the Company’s IPO on November 13, 2019, the remaining
16,000,000 shares of convertible preferred stock that were issuable were no longer issuable. Accordingly, the preferred stock liability was extinguished and
because the transaction occurred between related parties, the resulting $25.6 million was accounted for as a capital contribution by the preferred
stockholders and recorded as part of additional paid-in capital on the consolidated balance sheets (see Note 7).

Item 9. Changes in and Disagreements With Accountants on Accounting and Financial Disclosure.

None.

Item 9A. Controls and Procedures.

Evaluation of Disclosure Controls and Procedures

As of December 31, 2019, our management, with the participation and supervision of our principal executive officer and our principal financial

officer, evaluated our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act). The term “disclosure
controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, means controls and other procedures of a company that are
designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded,
processed, summarized and reported, within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without
limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under
the Exchange Act is accumulated and communicated to the Company’s management, including its principal executive and principal financial officers, as
appropriate to allow timely decisions regarding required disclosure. Management recognizes that any controls and procedures, no matter how well designed
and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost
benefit relationship of possible controls and procedures. Based on this evaluation, our principal executive officer and our principal financial officer
concluded that solely as a result of the material weaknesses in our internal control over financial reporting described below, our disclosure controls and
procedures were not effective as of December 31, 2019 to provide reasonable assurance that information we are required to disclose in reports that we file
or submit under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in SEC rules and forms, and that
such information is accumulated and communicated to our management, including our principal executive officer and our principal financial officer, as
appropriate, to allow timely decisions regarding required disclosure.

Remediation Efforts on Previously Reported Material Weaknesses

During the audit of our consolidated financial statements for the period from January 18, 2018 (inception) to December 31, 2018, material
weaknesses were identified in our internal control over financial reporting. A material weakness is a deficiency or 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 by the company’s internal controls. The material weaknesses that were identified related to
the following:

•

•

We did not have an internal finance department. Consequently, we lacked sufficient personnel with an appropriate level of knowledge and
requisite U.S. generally accepted accounting principles expertise to identify, evaluate and account for complex and non-routine transactions
and an adequate supervisory review structure that is needed to comply with financial reporting requirements.

We did not have an adequate assessment of risks that could significantly impact internal controls over financial reporting and did not
effectively design and monitor controls in response to the risks of material misstatement.

132

 
 
 
 
In 2019, we implemented plans to remedy these material weaknesses and as of December 31, 2019 our remediation efforts were ongoing. While we

believe that these efforts have improved and will continue to improve our internal control over financial reporting, remediation of the material weaknesses
will require validation and testing of the design and operating effectiveness of internal controls over a sustained period of financial reporting cycles
resulting in the reporting of these material weaknesses as of December 31, 2019. We have implemented and are in the process of implementing additional
measures and risk assessment procedures designed to improve our disclosure controls and procedures and internal control over financial reporting to
address the underlying causes of these material weaknesses, including the implementation of appropriate segregation of duties, formalization of accounting
policies and controls, and implementation of accounting systems to automate manual processes. In 2019, we also hired our Chief Financial Officer,
principal accounting officer and additional qualified accounting and finance personnel, formalized our hiring practices, engaged financial consultants to
enable the implementation of internal controls over financial reporting and are actively recruiting a new audit committee chair and financial expert
(following the resignation of Tomer Kariv, our audit committee chair and financial expert, from our board of directors in December 2019).

We cannot assure you that we have identified all, or that we will not in the future have additional, material weaknesses. Material weaknesses may

still exist when we report on the effectiveness of our internal control over financial reporting as required by reporting requirements under Section 404 of the
Sarbanes-Oxley Act.

Changes in Internal Control over Financial Reporting

Other than the changes intended to remediate the material weaknesses noted above, no change in our internal control over financial reporting (as

defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) occurred during the quarter ended December 31, 2019 that has materially affected, or is
reasonably likely to materially affect, our internal control over financial reporting.

Management’s Annual Report on Internal Control Over Financial Reporting

This Annual Report on Form 10-K does not include a report of management’s assessment regarding our internal control over financial reporting (as

defined in Rule 13a-15(f) under the Exchange Act) or an attestation report of our independent registered accounting firm due to a transition period
established by rules of the Securities and Exchange Commission for newly public companies.

Attestation Report of Registered Public Accounting Firm

As an emerging growth company, we are not required to provide an attestation report on our internal control over financial reporting issued by the

Company’s independent registered public accounting firm.

Code of Conduct

We have adopted a written code of business conduct and ethics that applies to our directors, officers and employees, including our principal
executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions. A copy of the code is
available on the Corporate Governance section of our website, which is located at http://ir.89bio.com/corporate-governance/governance-overview. We
intend to disclose on our website any amendments to, or waivers from, the code of business conduct and ethics that are required to be disclosed pursuant to
the disclosure requirements of Item 5.05 of Form 8-K within four business days following the date of the amendment or waiver.

Audit Committee and Audit Committee Financial Expert

We have a separately-designated standing audit committee established in accordance with Section 3(a)(58)(A) of the Exchange Act. Dr. DiRocco
and Dr. Hayden serve on the audit committee. Our board of directors has determined that each member of the audit committee is “independent” for audit
committee purposes as that term is defined in the rules of the SEC and the applicable Nasdaq Listing Rules, and has sufficient knowledge in financial and
auditing matters to serve on the audit committee. We do not currently have an audit committee financial expert as defined in Item 407(d)(5) of Regulation
S-K promulgated under the Securities Act or audit committee chair following Mr. Kariv’s resignation from the board of directors in December 2019.
However, our board of directors intends to retain an audit committee financial expert and audit committee chair in the near future.

Mr. Palekar, Dr. Mansbach and Mr. Le-Nguyen commenced employment as of July 16, 2018, December 17, 2018 and March 18, 2019, respectively.
Following the end of the fiscal year, we awarded each NEO a bonus in respect of company and individual performance in fiscal year 2019 and, for Dr. Mansbach $35,000 in respect of
his efforts in connection with the completion of our initial public offering.
Amounts shown in this column represent the aggregate grant date fair value (calculated in accordance with FASB Accounting Standards Codification Topic 718) of stock options
granted during the year. A description of the methodologies and assumptions we use to value equity awards and the manner in which we recognize the related expense are described in
Note 9 to our consolidated financial statements included elsewhere in this Annual Report on Form 10-K, Share-Based Compensation. These amounts may not correspond to the actual

process, Dr. Mansbach’s annualized base salary was $380,000, and Mr. Le-Nguyen’s annualized base salary was $340,000.

Incentive Compensation

Annual Incentive. For fiscal year 2019, Mr. Palekar, Dr. Mansbach and Mr. Le-Nguyen had target bonus opportunities equal to 45% of base salary

through July 15, 2019 and 50% thereafter, 35% of base salary and 30% of base salary, respectively (subject to proration for any partial-year service).

Following the end of the fiscal year, our board of directors evaluated the performance of Mr. Palekar, Dr. Mansbach and Mr. Le-Nguyen, and based
on Company and individual performance in 2019, determined to award bonuses to the named executive officers as disclosed in the Summary Compensation

offering.

Equity Incentive. During 2019, all of our named executive officers received stock option awards under our 89Bio Ltd. 2018 Equity Incentive Plan

(the “2018 Plan”). In connection with the Reorganization, in September 2019, our board of directors adopted and our stockholders approved our 2019
Equity Incentive Plan (the “2019 Plan”), the successor to the 2018 Plan. All stock awards granted under the 2018 Plan prior to the effective time of the
2019 Plan that were outstanding as of the effectiveness of the 2019 Plan were canceled and replaced with equivalent awards under the 2019 Plan. See the
table titled “Outstanding Equity Awards at 2019 Fiscal-Year End” for more information with respect to these grants.

Post-Employment Compensation and Change in Control Payments and Benefits

Severance

Pursuant to the terms of the offer letter agreements with the NEOs, upon a termination without cause (as defined in the agreements) not in
connection with a change in control (as defined in the agreements), the NEOs will receive, subject to execution and non-revocation of a release of claims in
favor of the Company (the “release condition”), severance equal to six months (in the case of Mr. Palekar), four months (in the case of Dr. Mansbach) or
three months (in the case of Mr. Le-Nguyen) of the base salary as then in effect, a pro-rata amount of the target bonus opportunity based on the number of
months employed during the year of termination and payment or reimbursement of COBRA premiums for up to six months (in the case of Mr. Palekar),
four months (in the case of Dr. Mansbach) or three months (in the case of Mr. Le-Nguyen), or, if sooner, until eligible for similar coverage through another
employer.

If the NEO is terminated without cause or for good reason (as defined in the agreements) within 90 days prior to, or 12 months following, the

consummation of a change in control, then, subject to the release condition, the benefits described above will be provided for 12 months (in the case of Mr.
Palekar) or six months (in the case of the other NEOs) and all outstanding equity awards will vest in full.

401(k) Plan

We offer eligible employees, including our NEOs based in the United States, the opportunity to participate in our tax-qualified 401(k) plan.
Employees can contribute 1%-100% of their eligible earnings up to the Internal Revenue Service’s annual limits on a before-tax basis. For every dollar an
employee contributes up to 6% of their compensation, we may contribute 25 cents per dollar, provided that there are no matching contributions in excess of
1.5% of eligible IRS compensation. Matches provided to our NEOs are reflected in the “All Other Compensation” column of the Summary Compensation
Table above. Our funds are 100% vested after the completion of one year of service.

Dr. Hayden is party to a letter agreement with the Company pursuant to which the Company pays him a monthly fee of $3,333 for service on the Board. The fees payable to the non-
employee directors for their service on the board of directors from the completion of our initial public offering through the end of the fiscal year have not yet been determined. The
Company expects to determine and pay such amounts in the first quarter of fiscal 2020 and will disclose such payments via a Current Report on Form 8-K.
Amounts shown in this column represent the aggregate grant date fair value (calculated in accordance with FASB Accounting Standards Codification Topic 718) of stock options
granted during the year. A description of the methodologies and assumptions we use to value equity awards and the manner in which we recognize the related expense are described in
Note 9 to our consolidated financial statements included elsewhere in this Annual Report on Form 10-K, Share-Based Compensation. These amounts may not correspond to the actual
value eventually realized by the director because the value depends on the market value of our common stock at the time the award is exercised. As of December 31, 2019, Dr. Hayden
held 134,214 outstanding stock options, of which 36,692 were exercisable. No other non-employee director held any outstanding equity awards as of such date.

We did not compensate Mr. Palekar for his service on our board of directors during 2019 and we do not expect to compensate our employee

directors for their service on our board of directors in the future.

Non-Employee Director Compensation Policy

Our board of directors has adopted a non-employee director compensation policy that went into effect following our initial public offering. Under

the policy, each director who is not an employee was entitled to receive cash compensation as set forth below:

Annual retainer for board of directors membership
Additional annual retainer for service as a committee chair*
Additional annual retainer for service as chairman of the board of directors

  $
  $
  $

40,000 
10,000 
60,000  

*

Applies with respect to each of the audit, compensation and nominating and corporate governance committees.

Following the end of the fiscal year, our board of directors approved the following changes to the non-employee director compensation policy:

Annual retainer for board of directors membership (other than the chair)
Additional annual retainer for service as chair of the audit committee
Additional annual retainer for service as chair of the compensation and governance
   committees
Additional annual retainer for service as a member of the audit committee
Additional annual retainer for service as a member of the compensation committee
Additional annual retainer for service as a member of the governance committee
Annual retainer for service as chairman of the board of directors

We pay all such amounts in quarterly installments.

In addition, the compensation committee of our board of directors may in its discretion grant equity awards to any or all non-employee directors

under the 2019 Plan. Such awards may include: (i) an initial, one-time equity award granted to a new non-employee director upon his or her election to our
board of directors; (ii) equity awards granted to non-employee directors on an annual basis for their service on our board of directors; and/or (iii) equity
awards granted to non-employee directors on an annual basis for their service in a leadership role or on a committee of our board of directors. During 2019,
prior to our initial public offering, we awarded Dr. Hayden, our sole independent director, 9,380 stock options that vested 25% on April 16, 2019 with the
remainder vesting in equal quarterly installments thereafter and 36,367 stock options that will vest 25% on July 23, 2020 with the remainder vesting in
equal quarterly installments thereafter.  

We reimburse all necessary and reasonable out-of-pocket expenses incurred by non-employee directors in connection with their service on our

board of directors, subject to any applicable Company policies that may be in effect from time to time.

A non-employee director may decline all or any portion of his or her compensation by giving notice to us prior to, as the case may be, the date cash

is to be paid or equity awards are to be granted.

Our board of directors periodically reviews our director compensation program and may revise the compensation arrangements for our directors

from time to time.

Compensation Committee Interlocks and Insider Participation

None of the members of our compensation committee has at any time during the prior three years been one of our officers or employees. None of

our executive officers currently serves, or in the past fiscal year has served, as a member of our board of directors or compensation committee of any entity
that has one or more executive officers serving on our board of directors or compensation committee.

We are a party to a right of first refusal and co-sale agreement, effective as of September 17, 2019 (the “ROFR Agreement”), with our stockholders

who previously held our Series A convertible preferred shares, including our 5% stockholders and entities affiliated with our directors. The ROFR
Agreement terminated upon completion our IPO.

Other than the above described sales of securities, the IRA, the Voting Agreement, the ROFR Agreement and the compensation arrangements for

our named executive officers and directors, which are described elsewhere in the “Executive and Director Compensation” sections of this Annual Report on
Form 10-K, we have not been a party to any transaction since January 18, 2018, our inception, in which the amounts involved exceeded or will exceed the
lesser of $120,000 or one percent of the average of our total assets at year end for the last two years, and any of our directors, executive officers or holders
of more than 5% of our capital stock, or any member of the immediate family of, or person sharing the household with, the foregoing persons, had or will
have a direct or indirect material interest.1

Board Determination of Independence

Rule 5605 of the Nasdaq Listing Rules requires a majority of a listed company’s board of directors to be comprised of independent directors within

one year of listing. In addition, the Nasdaq Listing Rules require that, subject to specified exceptions, each member of a listed company’s audit,
compensation and nominating and corporate governance committees be independent under the Securities Exchange Act of 1934, as amended (the
“Exchange Act”). Audit committee members must also satisfy the independence criteria set forth in Rule 10A-3 under the Exchange Act, and compensation
committee members must also satisfy the independence criteria set forth in Rule 10C-1 under the Exchange Act. Under Rule 5605(a)(2) of the Nasdaq
Listing Rules, a director will only qualify as an “independent director” if, in the opinion of our board of directors, that person does not have a relationship
that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. In order to be considered independent for
purposes of Rule 10A-3, a member of an audit committee of a listed company may not, other than in his or her capacity as a member of the audit
committee, the board of directors, or any other board committee, accept, directly or indirectly, any consulting, advisory, or other compensatory fee from the
listed company or any of its subsidiaries or otherwise be an affiliated person of the listed company or any of its subsidiaries. In order to be considered
independent for purposes of Rule 10C-1, the board must consider, for each member of a compensation committee of a listed company, all factors
specifically relevant to determining whether a director has a relationship to such company which is material to that director’s ability to be independent from
management in connection with the duties of a compensation committee member, including, but not limited to: (1) the source of compensation of the
director, including any consulting advisory or other compensatory fee paid by such company to the director; and (2) whether the director is affiliated with
the company or any of its subsidiaries or affiliates.

Our board of directors undertook a review of the composition of our board of directors and its committees and the independence of each director.

Based upon information requested from and provided by each director concerning his or her background, employment and affiliations, including family
relationships, our board of directors has determined that each of our current directors listed above under the “Directors and Executive Officers” section of
this Annual Report on Form 10-K (as well as Tomer Kariv, who served as a director until December 2019), with the exceptions of Rohan Palekar, is an
“independent director” as defined under Rule 5605(a)(2) of the Nasdaq Listing Rules (or was independent during the time of service on our board).
Mr. Palekar is not an independent director under Rule 5605(a)(2) because he is our chief executive officer.

Our board of directors also determined that each of the directors currently serving on the audit committee (Dr. DiRocco and Dr. Hayden) satisfy the
independence standards for audit committees established by the SEC and the Nasdaq Listing Rules, including the independence requirements contemplated
by Rule 10A-3 under the Exchange Act. In addition, our board of directors determined that each of the directors currently serving on the compensation
committee (Dr. Grunberg, Dr. Hayden and Ms. Naschitz) satisfy the independence standards for compensation committees established by the SEC and the
Nasdaq Listing Rules, including the independence requirements contemplated by Rule 10C-1 under the Exchange Act. In making such determinations, our
board of directors considered the relationships that each such non-employee director has with our company and all other facts and circumstances our board
of directors deemed relevant in determining independence, including the beneficial ownership of our capital stock by each non-employee director.

“Audit Fees” consist of fees for the audit of our annual financial statements, reviews of quarterly financial statements included in Quarterly Reports on Forms 10-Q, and services
provided in connection with SEC filings, including consents and comment and comfort letters.
“Tax Fees” consist of fees for services for tax compliance, tax advice, and tax planning.

Pre-Approval Policies and Procedures

Our audit committee has adopted procedures requiring the pre-approval of all audit and non-audit services performed by our independent registered
public accounting firm in order to assure that these services do not impair the auditor’s independence. These procedures generally approve the performance
of specific services subject to a cost limit for all such services. This general approval is to be reviewed, and if necessary modified, at least annually.
Management must obtain the specific prior approval of the audit committee for each engagement of the independent registered public accounting firm to
perform other audit-related or other non-audit services. The audit committee does not delegate its responsibility to approve services performed by the
independent registered public accounting firm to any member of management. Our audit committee has delegated authority to the committee chair to pre-
approve any audit or non-audit service to be provided to us by our independent registered public accounting firm provided that the fees for such services do
not exceed $100,000. Any approval of services by the committee chair pursuant to this delegated authority must be reported to the audit committee at the
next meeting of the committee.

DESCRIPTION OF REGISTRANT’S SECURITIES REGISTERED PURSUANT TO SECTION 12 OF THE SECURITIES EXCHANGE ACT
OF 1934

The following description of our capital stock is intended as a summary only and therefore is not a complete description of our capital

stock. This description is based upon, and is qualified by reference to, our second amended and restated certificate of incorporation (the “Amended
Certificate”), our second amended and restated bylaws (the “Amended Bylaws”) and applicable provisions of Delaware corporate law. You should read our
Amended Certificate and Amended Bylaws, which are filed as exhibits to our Annual Report on Form 10-K, to which this exhibit is also appended.

Our authorized capital stock consists of 100,000,000 shares of common stock and 10,000,000 shares of preferred stock.

Common Stock

Our Amended Certificate authorizes the issuance of up to 100,000,000 shares of our common stock. All outstanding shares of our common

stock are validly issued, fully paid and nonassessable.

The holders of our common stock are entitled to one vote per share on all matters submitted to a vote of stockholders. A majority vote of

the shares present in person or represented by proxy and entitled to vote on the subject matter is required for the holders of our common stock to take action
on all matters (except for election of directors (as discussed below)), except as otherwise required by law, our Amended Certificate or our Amended
Bylaws. Our Amended Certificate does not provide for cumulative voting in the election of directors. The holders of our common stock will receive ratably
any dividends declared by our board of directors out of funds legally available therefor. In the event of our liquidation, dissolution or winding-up, the
holders of our common stock will be entitled to share ratably in all assets remaining after payment of or provision for any liabilities.

Preferred Stock

Under the terms of our Amended Certificate, our board of directors has the authority, without further action by our stockholders, to issue up

to 10,000,000 shares of preferred stock in one or more series, to establish from time to time the number of shares to be included in each such series, to fix
the dividend, voting and other rights, preferences and privileges of the shares of each wholly unissued series and any qualifications, limitations or
restrictions thereon, and to increase or decrease the number of shares of any such series, but not below the number of shares of such series then outstanding.

Our board of directors may authorize the issuance of preferred stock with voting or conversion rights that could adversely affect the voting

power or other rights of the holders of our common stock. The issuance of preferred stock, while providing flexibility in connection with possible
acquisitions and other corporate purposes, could, among other things, have the effect of delaying, deferring or preventing a change in our control and may
adversely affect the market price of our common stock and the voting and other rights of the holders of our common stock.

Registration Rights

The holders of 7,077,366 shares of our common stock are entitled to rights with respect to the registration of these securities under the
Securities Act of 1933, as amended (the “Securities Act”). These rights are provided under the terms of our investors’ rights agreement, effective as of
September 17, 2019 (the “IRA”). The IRA includes demand registration rights, short-form registration rights and piggyback registration rights. All fees,
costs and expenses of underwritten registrations under this agreement will be borne by us and all selling expenses, including underwriting discounts and
selling commissions, will be borne by the holders of the shares being registered.

 
 
 
 
Demand Registration Rights

Beginning on May 6, 2020, the holders of 7,077,366 shares of our common stock are entitled to demand registration rights. Under the

terms of the IRA, we will be required, upon the written request of at least 50% of the holders of the registrable securities, including either OrbiMed Israel
Partners II, L.P. or OrbiMed Private Investments VI, LP, provided that the anticipated aggregate offering price is at least $10 million, to file a registration
statement on Form S-1 and use commercially reasonable efforts to effect the registration of these shares for public resale. The right to have such shares
registered on Form S-1 is further subject to other specified conditions and limitations.

Piggyback Registration Rights

Pursuant to the IRA, if we register any of our common stock either for our own account or for the account of other security holders, the
holders of registrable shares party to the IRA are entitled to include their shares in the registration, subject to certain marketing and other limitations. We
may terminate or withdraw any registration initiated before the effective date of such registration in our sole discretion.

Form S-3 Registration Rights

Pursuant to the IRA, if we are eligible to file a registration statement on Form S-3, upon the written request of at least 10% of the holders
of registrable securities to sell registrable securities at an aggregate price of at least $5 million, we will be required to use commercially reasonable efforts
to effect a registration of such shares. The right to have such shares registered on Form S-3 is further subject to other specified conditions and limitations.

Anti-Takeover Effects of Our Amended Certificate, Amended Bylaws and Delaware Law

Our Amended Certificate and our Amended Bylaws include a number of provisions that may have the effect of delaying, deferring or

preventing another party from acquiring control of us and encouraging persons considering unsolicited tender offers or other unilateral takeover proposals
to negotiate with our board of directors rather than pursue non-negotiated takeover attempts.

•

•

•

Issuance of undesignated preferred stock: Under our Amended Certificate, our board of directors has the authority, without further
action by the stockholders, to issue up to 10,000,000 shares of undesignated preferred stock with rights and preferences, including voting
rights, designated from time to time by our board of directors. The existence of authorized but unissued shares of preferred stock enables
our board of directors to make it more difficult to attempt to obtain control of us by means of a merger, tender offer, proxy contest or
otherwise.

Classified board: Our Amended Certificate establishes a classified board of directors consisting of three classes of directors, with
staggered three-year terms. Only one class of directors will be elected at each annual meeting of our stockholders, with the other classes
continuing for the remainder of their respective three-year terms. This provision may have the effect of delaying a change in control of
our board of directors.

Election and removal of directors and board vacancies: Our Amended Bylaws provide that directors will be elected by a plurality vote.
Our Amended Certificate and Amended Bylaws also provide that our board of directors has the right to increase or decrease the size of
the board and to fill vacancies on the board. Directors may be removed only for cause by the affirmative vote of the holders of at least
662⁄3% of the votes that all our stockholders would be entitled to cast in an annual election of directors. Only our board of directors is
authorized to fill vacant directorships. In addition the number of directors constituting our board of directors may be set only by
resolution adopted by a majority vote of the directors then in office. These provisions prevent stockholders from increasing the size of our
board of directors and gaining control of our board of directors by filling the resulting vacancies with its own nominees.

Requirements for advance notification of stockholder nominations and proposals: Our Amended Bylaws establish advance notice
procedures with respect to stockholder proposals and the nomination of candidates for election as directors that specify certain
requirements as to the timing, form and content of a stockholder’s notice. Business that may be conducted at an annual meeting of
stockholders will be limited to those matters properly brought before the meeting. These provisions may make it more difficult for our
stockholders to bring matters before our annual meeting of stockholders or to nominate directors at annual meetings of stockholders.

No written consent of stockholders: Our Amended Certificate provides that all stockholder actions be taken by a vote of the stockholders
at an annual or special meeting, and that stockholders may not take any action by written consent in lieu of a meeting. This limit may
lengthen the amount of time required to take stockholder actions and would prevent the amendment of our Amended Bylaws or removal
of directors by our stockholders without holding a meeting of stockholders.

No stockholder ability to call special meetings: Our Amended Certificate and Amended Bylaws provide that only a majority of the
members of our board of directors then in office may be able to call special meetings of stockholders and only those matters set forth in
the notice of the special meeting may be considered or acted upon at a special meeting of stockholders.

Amendments to certificate of incorporation and bylaws: Any amendment to our Amended Certificate will be required to be approved by
a majority of our board of directors as well as, if required by law or the Amended Certificate, a majority of the outstanding shares entitled
to vote on the amendment and a majority of the outstanding shares of each class entitled to vote thereon as a class, except that the
amendment of provisions to board classification, stockholder action, certificate amendments, and liability of directors must be approved
by not less than 662⁄3% of the outstanding shares entitled to vote on the amendment, voting together as a single class. Any amendment to
our Amended Bylaws must be approved by either a majority of our board of directors or not less than 662⁄3% of the outstanding shares
entitled to vote on the amendment, voting together as a single class.

These provisions are designed to enhance the likelihood of continued stability in the composition of our board of directors and its policies,

to discourage certain types of transactions that may involve an actual or threatened acquisition of us and to reduce our vulnerability to an unsolicited
acquisition proposal. We also designed these provisions to discourage certain tactics that may be used in proxy fights. However, these provisions could
have the effect of discouraging others from making tender offers for our shares and, as a consequence, they may also reduce fluctuations in the market price
of our shares that could result from actual or rumored takeover attempts.

Section 203 of the Delaware General Corporation Law

We are subject to the provisions of Section 203 of the Delaware General Corporation Law. In general, Section 203 prohibits a publicly held

Delaware corporation from engaging in a “business combination” with an “interested stockholder” for a three-year period following the time that this
stockholder becomes an interested stockholder, unless the business combination is approved in a prescribed manner.

Choice of Forum

Our Amended Certificate requires that the Court of Chancery of the State of Delaware be the exclusive forum for the following types of

actions or proceedings under Delaware statutory or common law: (1) any derivative action or proceeding brought on our behalf; (2) any action asserting a
breach of fiduciary duty owed by any director, officer or other employee to us or our stockholders; (3) any action asserting a claim against us or any
director or officer or other employee arising pursuant to the Delaware General Corporation Law, our Amended Certificate or Amended Bylaws; or (4) any
action asserting a claim against us or any director or officer or other employee that is governed by the internal affairs doctrine. This provision would not
apply to claims brought to enforce a duty or liability created by the Securities Exchange Act of 1934, as amended, or any other claim for which the federal
courts have exclusive jurisdiction. Our Amended Certificate provides further that the federal district courts of the United States will be the exclusive forum
for resolving any complaint asserting a cause of action arising under the Securities Act, subject to and contingent upon a final adjudication in the State of
Delaware of the enforceability of such exclusive forum provision. Although we believe these provisions benefit us by providing increased consistency in
the application of Delaware law for the specified types of actions and proceedings, the provisions may have the effect of discouraging lawsuits against us or
our directors or officers.

OFFICE LEASE

1.

This Lease is made this 5th day of December, 2019 between King Family Irrevocable Trust, as Landlord, and 89bio, Inc. as
Tenant,

WITNESSETH:

PREMISES

2.

Landlord  hereby  leases  to  Tenant  and  Tenant  hereby  hires  from  Landlord  those  certain  premises  (hereinafter  called
“premises”) being the entire 2nd floor of that certain building (hereinafter called “building”) known as 142 Sansome Street,
San Francisco, CA, 94104.

Said letting and hiring is upon and subject to the terms, covenants and conditions herein set forth and Tenant covenants as a
material part of the consideration for this Lease to keep and perform each and all of said terms, covenants and conditions by
it to be kept and performed and that this Lease is made upon the condition of such performance.

PURPOSE

3.

The premises shall be used for general office purposes and for no other use or purpose without the prior written consent of
Landlord.

TERM

4.

The term of this Lease shall be for two (2) years, commencing on the 15th day of January, 2020, and ending on the 14th day
of January, 2022 (the “Lease Term”).  Landlord shall provide Tenant access to the premises between December 9, 2019 to
December 19, 2019 without any obligation to pay rent for the sole purpose of Tenant’s work (see Exhibit C).  In addition,
beginning January 6, 2020 Tenant shall have access to complete Tenant’s Work and for installation of furniture, fixtures and
equipment.  No access to the premises will be given to Tenant during December 20, 2019 to January 5, 2020.

4.1 Option to Extend

Tenant shall have the option to extend the Lease Term for an additional period of two (2) years (the “Extension Term”).  The
Extension Term shall be on all the terms and conditions of this Lease, except that Tenant shall not have the option to further
extend the Lease Term and the rental rate will be at Market Value (as defined in Paragraph 6(c)).  Tenant must exercise its
option to extend the Lease Term by written notice to Landlord no less than one hundred eighty (180) days and no more than
two hundred seventy (270) days prior to the end of the initial “Lease Term.”

3

 
POSSESSION

5.

If Landlord, for any reason whatsoever, cannot deliver possession of the premises to Tenant at the commencement of the
term hereof, this Lease shall not be void or voidable, nor shall Landlord be liable to Tenant for any loss or damage resulting
therefrom, but in that event there shall be a proportionate reduction of rent covering the period between the commencement
of  the  term  and  the  time  when  Landlord  can  deliver  possession.    Should  Landlord  tender  possession  of  the  premises  to
Tenant  prior  to  the  date  specified  for  the  commencement  of  the  term,  and  Tenant  accepts  such  prior  tender,  such  prior
occupancy shall be subject to all terms, covenants, and conditions of this Lease.  No delay in delivery of possession shall
operate  to  extend  the  term  hereof.    Tenant  hereby  accepts  the  premises  in  its  “AS  IS”  condition  with  the  exception  that
Tenant, at Tenant’s sole cost and expense shall perform the work to the premises which is identified on Exhibit C attached
hereto.    The  premises  will  be  delivered  vacant,  broom  clean,  with  all  furniture  and  personal  property  removed  and  all
building systems in good operating condition.

RENT

6.

(a)  On  or  before  the  first  day  of  each  calendar  month  during  the  term  hereof  Tenant  shall  pay  to  Landlord,  as  minimum
monthly rent for the premises, the sum described in the Basic Lease Information.  The minimum monthly rent for any partial
month  (inclusive  of  the  month  of  February)  shall  be  prorated  at  the  rate  of  1/30  of  the  minimum  monthly  rent  per
day.  Notwithstanding the foregoing, Tenant shall pay to Landlord together with Tenant’s execution of this Lease, an amount
equal to the monthly base rent payable for the first full calendar month of the Lease term, which amount shall be applied to
the monthly base rent first due and payable hereunder.

Said rent shall be paid by Tenant to Landlord, c/o King & Co. Investment Management Inc., in advance, without deduction
or offset, in lawful money of the United States of America at King & Co. Investment Management Inc., 142 Sansome Street,
Suite 600, San Francisco, California, 94104 or to such other person or to such other place as Landlord may from time to
time designate in writing.

(b)
All charges and other amounts of any kind payable by Tenant to Landlord pursuant to this Lease shall be deemed
additional rent.  Landlord shall have the same remedies for default in the payment of additional rent as for default in the
payment of basic rent.  Basic rent and additional rent are collectively sometimes hereinafter referred to as rent.

(c)
If Tenant exercises its option to extend the Lease Term pursuant to Paragraph 4.1, the monthly rent payable during
such extension period shall be adjusted as of the first (1st) day of the extension term (the “Market Rent Date”) to the Market
Rent, determined as follows:

Definition.  The  term  “Market  Rent”  shall  mean  the  monthly  amount  per  rentable  square  foot  in  the  Premises  that  a
willing, non-equity, non-renewal, non-expansion new tenant would pay and a willing landlord would accept at arm’s length
for  space  in  a  comparable  building  or  buildings,  with  comparable  tenant  improvements,  in  a  comparable  location,  giving
appropriate  consideration  to  monthly  rental  rates  per  rentable  square  foot,  the  presence  or  absence  of  periodic  rent
escalations, operating expenses and tax pass-throughs, length of lease term, site and location of premises being leased, and
other generally applicable terms and conditions of tenancy for a similar building or buildings; provided, however, Market
Rent shall in no event be less than the minimum monthly rent during the last month of the initial Lease term.

4

 
Agreement on Market Rent. No later than one hundred eighty (180) days prior to the Market Rent Date, Landlord and
Tenant, upon notice from Landlord, shall agree on the Market Rent. If the parties are unable to agree on the Market Rent, the
parties shall choose  a  licensed  Real  Estate  Appraiser  who  shall  determine  the  Market Rent.  The cost of said Real Estate
Appraiser shall be borne equally by the parties.  If the parties are unable to agree on a licensed Real Estate Appraiser, each
party shall select one Appraiser to appraise the Market Rent.  If the difference between the two appraisals is 20% or less of
the  lower  appraisal,  then  the  Market  Rent  shall  be  the  average  of  the  two  appraisals.    If  the  difference  between  the  two
appraisals is greater than 20% of the lower appraisal, the two Appraisers shall select a third licensed Real Estate Appraiser
to appraise the Market Rent.  The Market Rent shall in such case be the average of the three appraisals.  The cost of the third
appraisal shall be borne equally by the parties.

Amendment of Lease.  Immediately after the Market Rent is determined pursuant to this Paragraph 6(c), Landlord and

Tenant shall execute an amendment to the Lease stating the new Base Rent in effect.

RENTAL ADJUSTMENT

7.

(a) In addition to the monthly rent provided for in Paragraph 6 hereof, Tenant shall pay to Landlord the sums set forth in the
following subparagraphs.  Tenant’s percentage share as set forth below has been calculated by dividing the number of square
feet of rentable area in the Premises by the number of square feet of rentable area in the building.  In the event the rentable
area of the building is changed, the Tenant’s percentage share shall be appropriately adjusted. Rentable area shall be based
upon  the  then  current  Building  Owners  and  Managers  Association  International  (BOMAI)  standard  method  of  floor
measurement  for  office  buildings.    Tenant  hereby  approves  and  accepts  Landlord’s  calculation  of  Tenant’s  current
percentage share as set forth below.

(b)

Tax Increases and Assessments

Tenant shall pay to Landlord Tenant’s percentage share of any increase in real property taxes and assessments or other fees
or charges of whatsoever kind or character imposed by a governmental agency which may be levied on the land and building
of which the premises are a part and personal property taxes levied on personal property of Landlord used in the operation of
said land and building above the amount of such taxes levied and assessed for the Base Tax Year, either by way of increase
in the rate or in the assessed valuation of said land and building or by imposition of any such charges by ordinance or statute
of any authority having jurisdiction.  For the purposes of the foregoing, (a) real and personal property taxes shall include,
without limitation, taxes of every kind and nature levied and assessed in lieu of or in substitution for existing or additional
real or personal property taxes on said land and building as well as any form of assessment, license, fee, levy, penalty, or tax
(other  than  income,  inheritance  or  estate  taxes),  imposed  by  any  authority  having  the  direct  or  indirect  power  to  tax,
including any city, county, state, or federal government, or any school, agriculture, lighting, drainage, or other improvement
district, as against any legal or equitable interest of Landlord in the premises or in the real property of which the premises
are a part, or as against Landlord’s right to rent or other income therefrom, or as against Landlord’s business of leasing

5

 
the  premises.    In  addition,  Tenant  shall  pay  one  hundred  per  cent  (100%)  of  any  increase  in  taxes  or  assessments  of
whatsoever  kind  and  nature  (including,  without  limitation,  all  personal  property  taxes)  caused  by  improvements  or
installations made by Tenant to the premises at any time during the term hereof.  The total amounts due hereunder shall be
paid  to  Landlord  on  or  before  the  date  full  payment  of  such  taxes  or  assessments  or,  if  payable  in  installments,  the  date
payment of the first installment of such taxes or assessments shall become due.  In the event said taxes or assessments are
charged  to  or  paid  or  payable  by  Landlord,  Tenant  forthwith  upon  demand  therefore,  shall  reimburse  Landlord  for  all
amounts of such taxes or assessments chargeable against Tenant pursuant to this subparagraph (b) and paid by Landlord.

(c)

Operating Expense Increases

Tenant shall pay to Landlord, at the times hereinafter set forth, an amount equal to Tenant’s percentage share of any increase
in direct expenses paid or incurred by Landlord on account of the operation or maintenance of the building above such direct
expenses paid or incurred by Landlord during the Base Expense Year.  “Direct Expenses” as used herein shall include all
direct  costs  of  operation  and  maintenance  as  determined  by  standard  accounting  practices  as  set  forth  in  the  Building
Owners  and  Managers  Association  International  (BOMAI)  chart  of  accounts  from  time  to  time  (excluding,  however,  any
and all taxes of the nature set forth in subparagraph (b) above) and shall include the following by way of illustration but not
limitation:  the cost of contesting by appropriate proceeding the amount or the validity of any of the aforementioned taxes or
fees;  water  and  sewer  charges;  insurance  premiums,  license;  permit  and  inspection  fees;  charges  for  all  power;  janitorial
services; labor; supplies; materials, equipment and tools; management expenses and the cost of capital improvements made
by  Landlord  to  the  building  that  are  intended  to  reduce  other  Operating  Expenses  or  that  are  required  under  any
governmental  law  or  regulation  that  is  not  applicable  to  the  building  as  of  the  date  of  this  Lease,  such  cost  or  allocable
portion  thereof  to  be  amortized  over  such  reasonable  period  as  Landlord  shall  determine  together  with  interest  on  the
unamortized balance at the rate that was paid by Landlord on funds borrowed for the purpose of constructing or installing
such capital improvements, or, if Landlord does not borrow such funds, would have been paid had the Landlord borrowed
funds  for  such  purpose  but  in  no  event  shall  such  interest  rate  exceed  the  maximum  rate  permitted  by  law.    “Direct
expenses”  as  used  herein  shall  not  include  depreciation  on  the  building,  real  estate  broker’s  commissions,  tenant
improvements, interest and capital items other than those referred to above.

Statements of the amount of direct expenses for the preceding calendar year and the amount of such increase payable by
Tenant shall be determined or estimated by Landlord and shall be given to Tenant on such date as Landlord shall from time
to  time  determine.   All  amounts  payable  by  Tenant  as  shown  on  said  statement  shall  be  paid  by  Tenant  within  the  time
required by said statement.  If during any such year Landlord shall revise its estimate of Tenant’s share of said expense for
said  year,  Landlord  shall  advise  Tenant  and  commencing  on  the  next  date  payment  of  additional  charges  are  due,  Tenant
shall  pay  all  additional  charges  based  on  such  revised  estimate  for  the  portion  of  the  year  already  elapsed  and  shall
commence paying the additional charges based on such revised estimate for the remainder of such year.

SECURITY DEPOSIT

8.

Simultaneously with the execution of this Lease, Tenant shall deposit with Landlord the sum of $71,992.20 which shall be
held  by  Landlord  as  security  for  the  faithful  performance  by  Tenant  of  all  the  terms,  covenants  and  conditions  of  this
Lease.  Provided that at the end of the term Tenant shall have delivered up the Premises to Landlord, broom clean, and in the
same  condition  as  at  the  commencement  date,  reasonable  wear  excepted,  said  sum  held  as  security  shall  be  returned  to
Tenant.  No interest shall be payable thereon and Landlord shall not be required to keep said sum in a separate account.  If
Tenant  fails  to  pay  any  Rent  or  other  charges  due  hereunder,  or  otherwise  defaults  with  respect  to  any  provision  of  this
Lease,  Landlord  may  at  its  option  apply  or  retain  all  or  any  portion  of  the  deposit  for  the  payment  of  any  Rent  or  other
charge  in  default  or  the  payment  of  any  other  sum  to  which  Landlord  may  become  obligated  by  Tenant’s  default,  or  to
compensate Landlord for any loss or damage which Landlord may suffer thereby.  If Landlord so uses or applies all or any
portion  of  the  deposit,  then  within  10  days  after  demand  therefor  Tenant  shall  deposit  cash  with  Landlord  in  an  amount
sufficient to restore the deposit to the full amount thereof, and Tenant’s failure to do so shall be a material breach of this
Lease.  Landlord’s application or retention of the deposit shall not constitute a waiver of Tenant’s default to the extent that
the  deposit  does  not  fully  compensate  Landlord  for  all  losses  or  damages  incurred  by  Landlord  in  connection  with  such
default and shall not prejudice any other rights or remedies available to Landlord under this Lease or by law.  Tenant hereby
unconditionally and irrevocably waives the benefits and protections of California Civil Code Section 1950.7, and, without
limitation  of  the  scope  of  such  waiver,  acknowledges  that  Landlord  may  use  all  or  any  part  of  the  security  deposit  to
compensate Landlord  for  damages  resulting  from  termination  of  this  Lease  and the tenancy created hereunder (including,
without limitation, damages recoverable under California Civil Code Section 1951.2).

No security or guaranty which may now or hereafter be furnished Landlord for the payment of the rent herein reserved or for
performance by Tenant of the other covenants or conditions of this Lease shall in any way be a bar or defense to any action
in unlawful detainer, or for the recovery of the premises, or to any action which Landlord may at any time commence for a
breach of any of the covenants or conditions of this Lease.

LATE CHARGE

9. All rent payable by Tenant to Landlord hereunder, if not received by Landlord within five (5) days after its due date, shall
bear  a  late  charge  equal  to  ten  percent  (10%)  of  the  amount  due  together  with  interest  accruing  from  the  date  due  at  the
maximum  interest  rate  permitted  by  law,  which  late  charge  and  interest  shall  be  payable  forthwith  upon  demand.    (The
foregoing shall be in addition to any other right or remedy of Landlord.)

USES PROHIBITED

10. Tenant shall not do or permit anything to be done in or about the premises nor bring or keep anything therein which will in
any  way  increase  the  rate  of  or  affect  any  fire  or  other  insurance  upon  the  building  or  any  of  its  contents  or  cause  a
cancellation of any insurance policy covering said building or contents.  Tenant shall not do or permit anything to be done in
or about the

7

 
premises which will in any way obstruct or interfere with the rights of other Tenants or occupants of the building or injure or
annoy them, or use or allow the premises to be used for any residential, immoral, unlawful or objectionable purpose, nor
shall Tenant cause, maintain or permit any nuisance in, on or about the premises.  No cooking devices or other odor causing
devices, water filtration devices or dispensers, dishwashers, loudspeakers or other similar device, system or apparatus which
can be heard or experienced outside the premises shall, without the prior written approval of Landlord, be used in or at the
premises.  Tenant shall not commit or suffer to be committed any waste in or upon the premises.

COMPLIANCE WITH LAW

11. Tenant shall not use or permit anything to be done in or about the premises which will in any way conflict with any law,
statute,  ordinance  or  governmental  rule,  regulation  or  requirement  now  in  force  or  which  may  hereafter  be  enacted  or
promulgated.    Tenant,  at  its  sole  cost  and  expense,  shall  promptly  comply  with  all  laws,  statutes,  ordinances  and
governmental rules, regulations or requirements now in force or which may hereafter be in force and with the requirements
of any board of fire underwriters or other similar body now or hereafter constituted relating to or affecting the condition, use
of occupancy of the premises, excluding structural changes not related to or affected by Tenant’s improvements or acts.  The
judgement of any court of competent jurisdiction or the admission of Tenant in an action against Tenant, whether Landlord
be a party thereto or not, that Tenant has violated any law, statute, ordinance or governmental rule, regulation or requirement
shall be conclusive of that fact as between Landlord and Tenant.  Further, Tenant shall at all times and in all respects comply
with  all  federal,  state  and  local  laws,  ordinances  and  regulations  (“Hazardous  Materials  Laws”)  relating  to  hygiene,
environmental  protection,  or  the  presence,  use  generation,  storage,  transportation  or  disposal  of  any  toxic  or  hazardous
substances, as the same may be amended from time to time, including without limitation, obtaining any required permits or
licenses, and Tenant shall handle, treat, manage and dispose of any and all toxic or hazardous substances in strict conformity
with all manufacturers’ instructions and prudent business practices.

ALTERATIONS

12. Tenant  shall  not  make  or  suffer  to  be  made  any  alterations,  additions  or  improvements  to  or  of  the  premises  or  any  part
thereof without the written consent of Landlord first had and obtained.  Any alterations, additions or improvements to or of
said premises, including without limitation any partitions, movable or otherwise, and all carpeting, shall at once become a
part  of  the  realty  and  belong  to  Landlord.    Movable  furniture,  equipment  and  trade  fixtures  shall  remain  the  property  of
Tenant.  If Landlord consents to the making of any alterations, additions or improvements to the premises by Tenant, the
same shall be made by Tenant at Tenant’s sole cost and expense and any contractor or person selected by Tenant to make the
same must first be approved of in writing by Landlord.  Upon the expiration or sooner termination of the term Tenant, upon
demand by Landlord, at Tenant’s sole cost and expense, forthwith and with all due diligence shall remove any alterations,
additions or improvements made by Tenant designated by Landlord to be removed, and Tenant, forthwith and with all due
diligence, at its sole cost and expense, shall repair any damage to the premises caused by such removal.  Tenant’s obligation
to remove any alterations, additions, improvements, fixtures and/or personal property and to repair any damage from such
removal shall survive the termination of this Lease.

8

 
Construction  of  the  alterations,  additions  or  improvements  shall  be  completed  in  accordance  with  drawings  and
specifications approved in advance in writing by Landlord, shall be carried out in a good and workmanlike manner, and shall
comply  with  all  applicable  requirements  of  governmental  authorities  and  such  additional  conditions  as  Landlord  may
reasonably impose.

Tenant hereby agrees to use reasonable efforts to notify Landlord if Tenant makes any alterations or improvements to the
Premises  that  might  impact  accessibility  to  the  Premises  or  Building  under  any  disability  access  laws,  and  any  disability
access  improvements  to  the  Building  or  Premises  required  due  to  alterations  or  improvements  made  to  the  Premises  by
Tenant shall be the responsibility of Tenant.  Landlord hereby agrees to use reasonable efforts to notify Tenant if Landlord
makes any alterations or improvements to the Premises that might impact accessibility to the Premises or Building under any
disability access laws.

REPAIR

13. By  entry  hereunder  upon  the  commencement  of  the  term  hereof,  Tenant  accepts  the  premises  as  being  in  good,  sanitary
order, condition and repair.  Tenant, at Tenant’s sole cost and expense, shall keep the premises and every part thereof in good
condition  and  repair,  damage  thereto  by  fire,  earthquake,  act  of  God  or  the  elements  not  caused  by  Tenant’s  negligent  or
willful act excepted, Tenant hereby waiving all rights to make repairs at the expense of the Landlord as provided by law,
stature  or  ordinance  now  or  hereafter  in  effect,  including,  without  limitation,  the  provisions  of  California  Civil  Code
Sections 1932(1), 1941 and 1942.  Upon the expiration or sooner termination of the term hereof, Tenant shall surrender the
premises to Landlord in the same condition as when received, ordinary wear and tear and damage by fire, earthquake, act of
God or the elements excepted, unless caused by Tenant’s negligent or willful act. It  is  specifically understood  and  agreed
that Landlord has no obligation and has made no promises to alter, remodel, improve, repair, decorate or paint the premises
or any part thereof and that no representations respecting the condition of the premises or the building have been made by
Landlord  to  Tenant.  There  shall  be  no  abatement  of  Rent  and  no  liability  to  Landlord  by  reason  of  any  injury  or  to
interference with Tenant’s business arising from the making of any repairs or performance of any maintenance obligations
by  the  Landlord.    Landlord  shall  be  responsible  for  maintenance,  repairs  and  replacement,  as  necessary,  of  structured
elements, building systems and common areas.

ABANDONMENT

14. Tenant shall not vacate or abandon the premises at any time during the term hereof, and if Tenant shall abandon, vacate or
surrender the premises or be dispossessed by process of law, or otherwise, any personal property belonging to Tenant and
left on the premises shall be deemed to be abandoned, at the option of Landlord.

LIENS

15. Tenant shall keep the premises and the building and the land upon which the building is situated free from any liens arising
out of any work performed, materials furnished or obligations incurred by Tenant.  Tenant shall in the event of the filing of
any such lien, post any bond required to release the premises therefrom.  Should Tenant fail to remove any such lien within
five (5) business days after notice to do so from Landlord, Landlord may, in addition to any other remedies, record a bond
pursuant to California Civil Code Section 3143 and all amounts incurred by Landlord in so doing shall become immediately
due  and  payable  by  Tenant  to  Landlord  as  additional  rent.    Landlord  shall  have  the  right  to  post  and  keep  posted  on  the
Premises any notices that may be provided by law or which Landlord may deem to be proper for the protection of Landlord,
the Premises and the building from such liens.

9

 
ASSIGNMENT AND SUBLETTING

16.

(a) Tenant shall not mortgage, pledge, hypothecate or encumber this Lease or any interest therein.  Tenant shall not assign
this Lease or sublet or suffer any other person (the agents and servants of Tenant excepted) to occupy or use the premises, or
any part thereof, or sublet any right or privilege appurtenant thereto without the prior written consent of Landlord first had
and  obtained,  which  consent  shall  not  be  unreasonably  withheld.    Landlord’s  consent  to  one  assignment,  subleasing  or
occupancy shall not be deemed to be a consent to any subsequent assignment, subleasing or occupancy.

Provided further and notwithstanding anything herein before set forth:  In the event that at any time or from time
(b)
to time during the term of this Lease, Tenant desires to assign this Lease or sublet all or any part of the Premises, Tenant
shall notify the Landlord in writing (the “Transfer Notice”) of the terms of the proposed assignment or subletting, and, in the
case of a sublease, the area so proposed to be sublet and shall give Landlord the right to (x) terminate this Lease or (y) sublet
from Tenant such space proposed to be subleased on the same terms as those contained in the Sublet Notice.  Such option
shall be exercisable by Landlord in writing for a period of 15 days after receipt of the Sublet Notice.

If  Landlord  fails  to  exercise  its  option  and  Tenant  desires  to  complete  the  proposed  sublease,  Tenant  shall  deliver  an
executed copy of such sublease to Landlord in order to obtain its consent as required in paragraph 16(a) above.  If Landlord
consents to a sublease, then such sublease shall be subject to and made upon the following terms:

(i) any such sublease shall be subject to the terms of this Lease and the term thereof may not extend beyond
the expiration of the term of this Lease; and

(ii) no subtenant shall have a right to further sublease its premises.

If Landlord fails to exercise such option, and Tenant fails to consummate a sublease with a third party within 60 days after
the expiration of Landlord’s option period on the same terms and conditions contained in the Sublet Notice, Tenant shall be
required to deliver a new Sublet Notice to Landlord and comply with the terms and conditions set forth above before any
further subletting shall be permitted.

Any rent or other consideration realized by Tenant under any assignment or sublease, in excess of the rent and all
(c)
other  amounts  (including  without  limitation,  Tenant’s  share  of  the  increases)  payable  hereunder  (or  the  amount  thereof
proportionate  to  the  portion  of  the  premises  subject  to  such  sublease  or  assignment)  and  reasonable  commissions  and  the
cost  of  any  alterations  incurred  in  connection  with  such  sublease  or  assignment,  shall  be  divided  and  paid  fifty  percent
(50%) to Landlord and fifty percent (50%) to Tenant.

(d)
the primary liability of Tenant to pay rent and perform other obligations of Tenant under this Lease.

Regardless of Landlord’s consent, no subletting nor assignment shall release Tenant of Tenant’s obligation or alter

10

 
Tenant  shall  pay  Landlord’s  reasonable  cost,  including  without  limitation  of  any  legal  fees,  which  incurred  in
(e)
connection with Tenant’s request to assign this Lease or sublet the premises, regardless whether or not the Landlord consents
to the proposed transfer.

If Tenant is a corporation or a partnership, the transfer (as a consequence of a single transaction) of fifty percent
(f)
(50%) or more of the beneficial ownership interest of the voting stock of Tenant issued and outstanding as of the date hereof
or of the partnership interests in Tenant, as the case may be, shall constitute an assignment hereunder for which such consent
is required.  Any such sublease or assignment without the written consent of Landlord shall be void, and, at the option of
Landlord, shall terminate this Lease.

(g)
Tenant will have the right in the event of a merger, consolidation, reorganization, or recapitalization, whether or
not Tenant survives as the surviving corporation, to assign or transfer this Lease to such surviving corporation; provided,
however, such right of assignment or transfer will be limited to an assignee (i) whose net worth is equal to or greater than
the net worth of Tenant at the time of such assignment or transfer and (ii) whose historical profitability (in both duration and
amount) is equal to or greater than Tenant, as viewed at the time of the proposed assignment or transfer.  In the event Tenant
contemplates making an assignment or transfer as provided in this subparagraph, Tenant will give thirty (30) days’ notice to
Landlord of its intention to make such assignment or transfer and will furnish Landlord with all pertinent information as to
the net worth of the proposed assignee or transferee.

INDEMNIFICATION OF LANDLORD

17. Tenant agrees to indemnify and defend Landlord against and save Landlord harmless from any and all loss, cost, liability,
damage  and  expense,  including  without  limitation  penalties,  fines  and  reasonable  attorneys’  fees  and  costs,  incurred  in
connection with or arising from any cause whatsoever in, on or about the premises, including without limiting the generality
of the foregoing:  (1) any default by Tenant in the observance or performance of any of the terms, covenants or conditions of
this Lease on Tenant’s part to be observed or performed, or (2) the use of occupancy or manner of the use or occupancy of
the  premises  by  Tenant  or  any  other  person  or  entity  claiming  through  or  under  Tenant,  including  without  limitation,  the
presence, use, generation, storage, transportation or disposal of any toxic or hazardous substances, or (3) the condition of the
premises  or  any  occurrence  or  happening  on  the  premises  from  any  cause  whatsoever,  or  (4)  any  acts,  omissions  or
negligence  of  Tenant  or  of  Tenant’s  agents,  contractors,  employees,  subtenants,  licensees,  invitees  or  visitors  or  any  such
person  or  entity,  in,  on  or  about  the  premises  or  the  building,  either  prior  to  the  commencement  of,  during,  or  after  the
expiration of the term, including without limitation any acts, omissions or negligence in the making or performing of any
alterations.  Tenant further agrees to indemnify, defend and save harmless Landlord and Landlord’s agents from and against
any and all loss, cost, liability, damage and expense, incurred in connection with or arising from any claims by any persons
by reason of injury to persons or damage to property occasioned by any use, occupancy condition, occurrence, happening,
act, omission or negligence referred to in the preceding sentence.  In the event any action or proceeding is brought against
Landlord  for  any  claim  against  which  Tenant  is  obligated  to  indemnify  Landlord  hereunder,  Tenant  upon  notice  from
Landlord shall defend such action or proceeding at Tenant’s sole expense by counsel approved by Landlord, which approval
shall not be unreasonably withheld.  The provisions of this Paragraph 17 shall survive the expiration or earlier termination of
this lease.

11

 
INSURANCE

18. Tenant agrees to keep in force during the term hereof, at Tenant’s expense, (i) public liability and property damage insurance
with combined single limits in the amount of not less than $2 million ($2,000,000.00), (ii) employer’s liability for bodily
injury  by  disease  per  person  and  bodily  injury  by  accident  with  minimum  limits  of  $1  million  ($1,000,000),  and  (iii)
statutory  workers’  compensation,  (iv)  an  “all  risk”  or  “special  causes  of  loss”  property  policy  in  the  amount  of  the  full
replacement cost covering Tenant’s personal property and any alterations made by or at the request of Tenant, with Landlord
insured as its interest may appear, and (v) an “all risk” or “special causes of loss” policy of business interruption and/or loss
of  income  insurance  covering  a  period  of  one  (1)  year.    Said  public  liability  policy  shall  name  Landlord  as  an  additional
insured,  and  shall  insure  Landlord’s  contingent  liability  as  respects  acts  or  omissions  of  Tenant,  shall  be  issued  by  an
insurance  company  licensed  to  do  business  in  the  state  of  California;  and  shall  provide  that  said  insurance  shall  not  be
cancelled  or  amended  unless  thirty  (30)  days  prior  written  notice  to  Landlord  is  first  given.    Said  policy  or  a  certificate
thereof  shall  be  delivered  to  Landlord  by  Tenant  prior  to  the  commencement  of  the  term  and  each  renewal  of  such
insurance.  Tenant hereby waives all rights of subrogation against Landlord to which any insurance carrier may at any time
become entitled under any policy of insurance carried by Tenant.  Landlord herby waives all rights of subrogation against
Tenant to which any insurance carrier may at any time become entitled under any policy of insurance carried by Landlord.

UTILITIES

19. Landlord shall furnish to the premises, during the period from 8:00 a.m. to 5:00 p.m., Monday through Friday, except for
New Year’s Day, Washington’s Birthday, Memorial Day, Independence Day, Labor Day, Thanksgiving, Christmas, and other
such  holidays  as  are  generally  recognized  in  San  Francisco,  California,  and  subject  to  rules  and  regulations  from  time  to
time established by Landlord:  (a) heating, air conditioning in amounts required in Landlord’s reasonable judgement, for the
normal use and occupancy of the Premises, (b) passenger elevator service, (c) electricity, (d) water for lavatory purposes and
(e)  janitorial  services  consistent  with  office  buildings  in  the  San  Francisco  financial  district  suitable  for  the  use  of  the
premises.  It is understood that such passenger elevator service, electricity and water will be available twenty-four (24) hours
a day, 365 days a year, subject to force majeure or security procedures.  At Tenant’s written request, lighting, heating and air
conditioning (“HVAC”) will be available at hours other than those specified above after twenty-four (24) hour written notice
to Landlord (provided that if Tenant fails to provide such written notice 24 hours in advance, Landlord shall nonetheless use
good faith efforts to provide such service) and upon Tenant’s agreement to pay Landlord’s charges for such services.  The
current charge for such non-standard HVAC is fifty-five dollars ($55) per hour per floor.  Tenant understands and agrees that
such costs are those currently charged by Landlord as of the date of this Lease, and that such figures are not intended in any
way  be  binding  upon  Landlord.    Landlord  shall  not  be  liable  for,  and  Tenant  shall  not  be  entitled  to  any  abatement  or
reduction  of  rent  by  reason  of  Landlord’s  failure  to  furnish  any  of  the  foregoing  when  such  failure  or  delay  is  caused  by
accident,  breakage,  repairs,  strikes,  lockouts  or  other  labor  disturbances  or  labor  disputes  of  any  character,  or  is  caused
directly or indirectly by the limitation, curtailment, rationing or restrictions on use of water, electricity, gas or any other form
of  energy  serving  the  premises  or  the  building,  or  by  any  other  cause,  similar  or  dissimilar.    Landlord  shall  not  be  liable
under  any  circumstances  for  loss  of  business  or  injury  to  property,  however  occurring,  through  or  in  connection  with  or
incidental to failure to furnish any of the foregoing. Tenant shall pay and provide for all services and utilities not furnished
by Landlord.  In no event, however, shall Landlord be liable to Tenant for any loss or damage, including the theft of Tenant’s
property arising out of or in connection with the failure of any security services, personnel or equipment.

12

 
Tenant will not, without the written consent of Landlord, use any apparatus or device in the premises which will in any way
increase the amount of electricity, cooling capacity or water usually furnished or supplied for use of the premises for general
office purposes or connect with electric current, except through existing electrical outlets in the premises, or water pipes, any
apparatus  or  device  for  the  purpose  of  using  electric  current  or  water.    If  Tenant  shall  require  water  or  electric  current  in
excess of that customarily furnished or supplied to other Tenants of the building for use of their premises for general office
purposes, Tenant shall first procure the consent of Landlord, which Landlord may refuse, to the use thereof.

PERSONAL PROPERTY AND OTHER TAXES

20. Tenant shall pay, before delinquency, (a) any and all taxes levied or assessed and which become payable during the term
hereof upon Tenant’s equipment, furniture, fixtures and other personal property located in the premises; (b) any and all taxes
or  increases  therein  levied  or  assessed  on  Landlord  or  Tenant  by  virtue  of  alterations,  additions  or  improvements  to  the
premises  made  by  Tenant  or  Landlord  at  Tenant’s  request;  and  (c)  any  and  all  taxes  payable  by  Landlord  (other  than  net
income taxes) whether or not now customary or within the contemplation of the parties hereto which are upon or measured
by the monthly rent or other charges payable hereunder, including, without limitation, any gross receipts tax or excise tax
levied by the City and County of San Francisco, the State of California, the Federal government or any other governmental
body with respect to the receipt of such rental.  In the event said taxes are charged to or paid or payable by Landlord, Tenant,
forthwith upon demand therefore, shall reimburse Landlord for all of such taxes paid by Landlord.

RULES AND REGULATIONS

21. Tenant  shall  faithfully  observe  and  comply  with  the  rules  and  regulations  printed  on  or  annexed  to  this  Lease  and  all
modifications of and additions thereto applicable to all Tenants of the building from time to time put into effect by Landlord
of which Tenant shall have notice.  Landlord shall not be responsible to Tenant for the nonperformance by any other Tenant
or occupant of the building of any of said rules and regulations. However, Landlord shall enforce its rules and regulations in
a non-discriminatory manner.

HOLDING OVER

22.

If Tenant holds possession of the premises after the term of this lease, Tenant shall, (at option of Landlord to be exercised by
Landlord’s giving written notice to Tenant and not otherwise) become a Tenant from month to month upon the terms and
conditions herein specified, so far as applicable, at a monthly rental equal to one hundred fifty percent (150%) of the office
base rent then being paid, payable in advance, in lawful money, and shall continue to be such Tenant until thirty (30) days
after Tenant shall have given to Landlord or Landlord shall have given to Tenant a written notice of intent to terminate such
monthly tenancy.  Unless Landlord shall exercise the option hereby given him, Tenant shall be a Tenant at sufferance only,
whether or not Landlord shall accept any rent from Tenant while Tenant is so holding over.  In addition, if the Premises are
not timely surrendered at the expiration or sooner termination of this Lease, Tenant hereby agrees to indemnify Landlord
against all loss or liability resulting from any delay by Tenant in so surrendering the Premises, including, but not limited to,
any claims made by any succeeding tenant, losses to Landlord due to lost opportunities to lease to succeeding tenants, and
actual attorneys’ fees and costs.

13

 
SUBORDINATION

23. This Lease shall be subject and subordinate at all times to all ground or underlying leases which may now exist or hereafter
be executed affecting the building and/or the land upon which the building is situated and to the lien of any mortgages or
deeds of trust in any amount or amounts whatsoever now or hereafter placed on or against said building and/or land or on or
against  the  Landlord’s  interest  or  estate  therein  or  on  or  against  any  ground  or  underlying  lease  without  the  necessity  of
having further instruments on the part of Tenant to effectuate such subordination.  Notwithstanding the foregoing, Tenant
covenants and agrees to execute and deliver, upon demand, such further instruments evidencing such subordination of this
Lease to such ground or underlying leases and to the lien of any such mortgages or deeds of trust as may be required by
Landlord.    Tenant  hereby  irrevocably  appoints  Landlord  the  attorney  in  fact  of  Tenant  to  execute  and  deliver  any  such
instrument or instruments for or in the name of Tenant. In the event of termination of any ground or underlying lease, or in
the event of foreclosure or exercise of any power of sale under any mortgage or deed of trust superior to this Lease or to
which this Lease is subject or subordinate, upon Tenant’s attornment to the Lessor under such ground or underlying lease or
to the purchaser at any foreclosure sale or sale pursuant to the exercise of any power of sale under any mortgage or deed of
trust,  this  Lease  shall  not  terminate  and  Tenant  shall  automatically  be  and  become  the  Tenant  of  said  Lessor  under  such
ground or underlying Lease or to said purchaser, whichever shall make demand therefore.

ENTRY BY LANDLORD

24. Landlord reserves and shall at any and all reasonable times, upon reasonable prior notice to Tenant, except in cases of an
emergency,  have  the  right  to  enter  the  premises  to  inspect  the  same,  to  supply  janitor  service  and  any  other  service  to  be
provided by Landlord to Tenant hereunder, to submit the premises to prospective purchasers or Tenants, to post notices of
non-responsibility, and to alter, improve or repair the premises and any portion of the building without abatement of rent and
may for that purpose erect scaffolding and other necessary structures where reasonably required by the character of the work
to be performed, always providing the entrance to the premises shall not be blocked thereby and further providing that the
business of Tenant shall not be interfered with unreasonably.  Tenant hereby waives any claim for damages for any injury or
inconvenience to or interference with Tenant’s business, any loss of occupancy of quiet enjoyment of the premises, and other
loss occasioned by such entry.  For each of the aforesaid purposes, Landlord shall at all times have and retain a key with
which to unlock all of the doors, in, upon and about the premises excluding Tenant’s vaults and safes, and Landlord shall
have the right to use any and all means which Landlord may deem proper to open said doors in an emergency in order to
obtain entry to the premises, and any entry to the premises obtained by Landlord by any of said means, or otherwise, shall
not under any circumstances be construed or deemed to be a forcible or unlawful entry into or a detainer of the premises or
an eviction of Tenant from the premises or any portion thereof.

14

 
INSOLVENCY OR BANKRUPTCY

25. Either (a) the appointment of a receiver to take possession of all or substantially all of the assets of Tenant, (b) an assignment
by  Tenant  for  the  benefit  of  creditors,  or  (c)  any  action  taken  or  suffered  by  Tenant  under  any  insolvency,  bankruptcy  or
reorganization act shall constitute a breach of this Lease by Tenant.  Upon the happening of any such event this Lease shall
terminate five (5) days after written notice of termination from Landlord to Tenant.  In no event shall this Lease be assigned
or assignable by reason of any voluntary or involuntary bankruptcy proceedings nor shall any rights or privileges hereunder
be an asset of Tenant in any bankruptcy, insolvency or reorganization proceedings.

DEFAULT

26.

In the event of any breach or default of Lease by Tenant, which remains uncured after three (3) business days’ notice from
Landlord  to  Tenant,  or  any  non-monetary  breach  or  default  which  remains  uncured  after  fifteen  (15)  days’  notice  from
Landlord to Tenant, then Landlord, besides any other rights and remedies of Landlord at law or equity, shall have the right
either  to  terminate  Tenant’s  right  to  possession  of  the  premises  and  thereby  terminate  this  Lease  or  to  have  this  Lease
continue in full force and effect with Tenant at all times having the right to possession of the premises.  Any property of
Tenant removed may be stored in a public warehouse or elsewhere at the cost and for the account of Tenant.  Upon such
termination Landlord, in addition to any other rights and remedies (including rights and remedies under Subparagraphs (1),
(2) and (4) of Subdivision (a) of Section 1951.2 of the California Civil Code of any amendment thereto), shall be entitled to
recover from Tenant the worth at the time of award of the amount by which the unpaid rent for the balance of the term after
the time of award exceeds the amount of such rental loss that the Tenant proves could be reasonably avoided.  The worth at
the  time  of  award  of  the  amount  referred  to  in  subparagraphs  (1)  and  (2)  of  Subdivision  (a)  of  Section  1951.2  of  the
California Civil Code shall be computed by allowing interest at the maximum rate allowed by law.  The worth at the time of
the award of the amount referred to in subparagraph (3) of Subdivision (a) of Section 1951.2 of the California Civil Code
shall be computed by discounting such amount at the discount rate of the Federal Reserve Bank of San Francisco at the time
of the award plus 1%.

Any proof by Tenant of the amount of rental loss that could be reasonably avoided shall be made in the following manner:
Landlord and Tenant shall each select a licensed real estate broker in the business of renting property of the same type and
use as the premises and in the same geographic vicinity and such two real estate brokers shall select a third licensed real
estate broker and the three licensed real estate brokers so selected shall determine the amount of rental loss that could be
reasonably avoided for the balance of the term of this Lease after the time of award.  The decision of the majority of said
licensed real estate brokers shall be final and binding upon the parties hereto.

Should Landlord, following any breach or default of this Lease by Tenant, elect to keep this Lease in full force and effect,
with Tenant retaining the right to possession of the premises (notwithstanding the fact the Tenant may have abandoned the
leased premises), then Landlord, besides the rights and remedies specified in Section 1951.4 of the California Civil Code
“(lessor may continue lease in effect after lessee’s breach and abandonment and recover rent

15

 
as  it  becomes  due,  if  lessee  has  right  to  sublet  or  assign,  subject  only  to  reasonable  limitations)”  and  all  other  rights  and
remedies Landlord may have at law or equity, shall have the right to enforce all of Landlord’s rights and remedies under this
Lease.    Notwithstanding  any  such  election  to  have  this  Lease  remain  in  full  force  and  effect,  Landlord  may  at  any  time
thereafter elect to terminate Tenant’s right to possession of said premises and thereby terminate this Lease for any previous
breach or default which remains uncured, or for any subsequent breach or default.  If Tenant is in default even before the
move-in  date,  Tenant  shall  be  responsible  for  any  loss,  including,  but  not  limited  to  the  broker’s  commission,  Tenant
Improvement costs, rent, and any legal fees.

DESTRUCTION OR DAMAGE

27.

(a)  In  the  event  the  premises  or  a  portion  of  the  building  is  damaged  by  fire  or  other  insured  casualty,  Landlord  shall
diligently repair the same to the extent possible with the insurance proceeds received by Landlord, subject to the provisions
of  this  Section  hereinafter  set  forth,  if  such  repairs  can  in  Landlord’s  opinion  be  made  within  90  days  after  issuance  of  a
building  permit  therefor  under  the  laws  and  regulations  of  federal,  state  and  local  governmental  authorities  having
jurisdiction thereof.  In such event this Lease shall remain in full force and effect except that if such damage is not the result
of the negligence or willful misconduct of Tenant or Tenant’s agents, contractors, employees, subtenants, licensees, invitees
or visitors, an abatement of basic rent shall be allowed Tenant for such part of the premises as shall be rendered unusable by
Tenant  in  the  conduct  of  its  business  during  the  time  such  part  is  so  unusable.    Notwithstanding  the  foregoing,  if  such
damage shall occur during the final year of the term of this Lease, Landlord shall not be obligated to repair such damage, but
may instead elect to terminate this Lease upon written notice given to Tenant within 30 days after the date of such fire or
other casualty, in which event this Lease shall terminate as of the termination date specified in Landlord’s notice.

(b)
If such repairs cannot in Landlord’s opinion be made within 90 days after issuance of a building permit therefor or
if such damage is uninsured, Landlord may elect upon notice to Tenant given 60 days after the date of such fire or other
casualty to (i) repair or restore such damage, in which event this Lease shall continue in full force and effect, but basic rent
shall be partially abated as hereinabove in this Section provided or (ii) terminate this Lease in which event this Lease shall
terminate as of the termination date specified in Landlord’s notice.

(c)
A  total  destruction  of  the  building  automatically  shall  terminate  this  Lease.    Landlord  and  Tenant  acknowledge
that this Lease constitutes the entire agreement of the parties regarding events of damage or destruction, and Tenant waives
the provisions of California Civil Code Section 1932(2) and 1933(4) and any similar statute now or hereafter in force.

(d)
If the premises are to be repaired under this Section, Landlord shall repair at its cost any injury or damage to the
building itself and the initial improvements made by Landlord.  Tenant shall pay the cost of repairing or replacing all other
improvements in the premises and Tenant’s trade fixtures, furnishings, equipment and other personal property.

16

 
EMINENT DOMAIN

28.

If all or any part of the premises shall be taken or appropriated by any public or quasi-public authority under the power of
eminent domain, and such taking will substantially impair Tenant’s use of the premises for more than 90 days, either party
hereto shall have the right, at its option, to terminate this Lease.  If all or any part of the building of which the premises are a
part shall be taken or appropriated by any public or quasi-public authority under any power of eminent domain, Landlord
may terminate this Lease.  In either of such events, Landlord shall be entitled to and Tenant upon demand of Landlord shall
assign to Landlord any rights of Tenant to any and all income, rent, award, or any interest therein whatsoever which may be
paid or made in connection with such public or quasi-public use or purpose, and Tenant shall have no claim against Landlord
or  the  condemnor  for  the  value  of  any  unexpired  term  of  this  Lease.    If  a  part  of  the  premises  shall  be  so  taken  or
appropriated  and  neither  party  hereto  shall  elect  to  terminate  this  Lease,  the  rent  thereafter  to  be  paid  shall  be  equitably
reduced.

PLATS AND RIDERS

29. Clauses, plats and riders, if any, signed by Landlord and Tenant and endorsed on or affixed to this Lease are a part hereof,
and in the event of variation or discrepancy the duplicate original hereof, including such clauses, plats and riders, if any, held
by Landlord shall control.

ESTOPPEL CERTIFICATES

30. At  any  time  and  from  time  to  time,  upon  not  more  than  ten  (10)  business  days  prior  request  by  Landlord,  Tenant  shall
execute, acknowledge and deliver to Landlord a statement certifying the date of commencement of this Lease, stating that
this Lease is unmodified and in full force and effect (or if there have been modifications, that this Lease is in full force and
effect as modified and the date and nature of such modifications) and the dates to which the rent has been paid, and setting
forth such other matters as may reasonably be requested by Landlord.  Landlord and Tenant intend that any such statement
delivered pursuant to this paragraph may be relied upon by any mortgagee or the beneficiary of any Deed of Trust or by any
purchaser or prospective purchaser of the building.  Tenant hereby irrevocably appoints Landlord as its agent and attorney
in-fact to execute, acknowledge and deliver any such certificate in the name of and on behalf of Tenant, in the event that
Tenant fails to so execute, acknowledge and deliver any such certificate within 10 days after receipt thereof.

RIGHT OF LANDLORD TO PERFORM

31. All covenants and agreements to be kept or performed by Tenant under any of the terms of this Lease shall be performed by
Tenant at Tenant’s sole cost and expense and without any abatement of rent.  If Tenant shall fail to pay any sum of money,
other  than  rent,  required  to  be  paid  by  it  hereunder  or  shall  fail  to  perform  any  other  act  on  its  part  to  be  performed
hereunder, and such failure shall continue for ten (10) days after notice thereof by Landlord, Landlord may, but shall not be
obligated to, and without waiving any default of Tenant or releasing Tenant from any obligations of Tenant hereunder, make
any such payment or perform any such other act on Tenant’s part to be made or performed as in this Lease provided.  All
sums  so  paid  by  the  Landlord  and  all  necessary  incidental  costs,  together  with  interest  thereon  at  the  rate  of  ten  percent
(10%)  per  annum  from  the  date  of  such  payment  by  the  Landlord,  shall  be  paid  to  Landlord  forthwith  on  demand,  and
Landlord  shall  have  (in  addition  to  any  other  right  or  remedy  of  Landlord)  the  same  rights  and  remedies  in  the  event  of
nonpayment thereof by Tenant as in the case of default by Tenant in payment of rent.

17

 
ATTORNEY FEES

32.

If as a result of any breach or default on the part of Tenant under this Lease, Landlord uses the services of any attorney in
order to secure compliance with this Lease, Tenant shall reimburse Landlord upon demand as additional rent for any and all
reasonable  attorneys’  fees  and  expenses  incurred  by  Landlord,  whether  or  not  formal  legal  proceedings  are
instituted.  Should either party bring action against the other party, by reason of or alleging the failure of the other party to
comply with any or all of its obligations hereunder, whether for declaratory or other relief, then the party which prevails in
such  action  shall  be  entitled  to  its  reasonable  attorneys’  fees  and  expenses  related  to  such  action,  in  addition  to  all  other
recovery  or  relief.   A  party  shall  be  deemed  to  have  prevailed  in  any  such  action  (without  limiting  the  generality  of  the
foregoing) if such action is dismissed upon the payment by the other party of the sums allegedly due or the performance of
obligations  allegedly  not  complied  with,  or  if  such  party  obtains  substantially  the  relief  sought  by  it  in  the  action,
irrespective of whether such action is prosecuted to judgment.  In addition, if either party to this Lease becomes a party to or
is involved in any way in any action concerning this Lease or the premises by reason in whole or in part of any act, neglect,
fault or omission of any duty by the other party, its employees or contractors, the party subjected to said involvement shall
be entitled to reimbursement for any and all reasonable attorneys’ fees and costs.

SURRENDER OF PREMISES

33. The voluntary or other surrender of this Least by Tenant or mutual cancellation thereof shall not work a merger and, at the
option of Landlord, shall terminate all or any existing subleases or subtenancies, or at the option of Landlord, may operate as
an assignment to Landlord of any or all such subleases or subtenancies.

WAIVER

34. The waiver by Landlord or Tenant of performance of any term, covenant or condition herein contained shall not be deemed
to  be  a  waiver  of  such  term,  covenant  or  condition  or  any  subsequent  breach  of  the  same  or  any  other  term,  covenant  or
condition herein contained.  The subsequent acceptance of rent hereunder by Landlord shall not be deemed to be a waiver of
any preceding breach by Tenant of any term, covenant or condition of this Lease, other than the failure of Tenant to pay the
particular rent so accepted, regardless of Landlord’s knowledge of such preceding breach at the time of acceptance of such
rent.

NOTICES

35. All notices and demands which may or are required to be given by either party to the other hereunder shall be in writing.  All
notices  and  demands  by  Landlord  to  Tenant  shall  be  delivered  personally  or  sent  by  United  States  certified  or  registered
mail, postage prepaid, addressed to Tenant at the premises, or to Valence Law Group, PC, 2855 Mitchell Drive, Suite 260,
Walnut Creek, CA 94598 Fax: (415) 358-4570, krista@valencelaw.com, Attn: Krista Kim, or to such other place as Tenant

REQUIRED DISCLOSURES RELATED TO ACCESSIBILITY STANDARDS

44. For  purposes  of  Section  1938  of  the  California  Civil  Code,  Landlord  hereby  discloses  to  Tenant,  and  Tenant  hereby
acknowledges, that the Premises have not undergone inspection by a Certified Access Specialist (CASp).  As required by
Section 1938(c) of the California Civil Code, Landlord hereby states as follows:  “A Certified Access Specialist (CASp) can
inspect  the  subject  premises  and  determine  whether  the  subject  premises  comply  with  all  of  the  applicable  construction-
related  accessibility  standards  under  state  law.    Although  state  law  does  not  require  a  CASp  inspection  of  the  subject
premises, the commercial property owner or lessor may not prohibit the lessee or tenant from obtaining a CASp inspection
of  the  subject  premises  for  the  occupancy  or  potential  occupancy  of  the  lessee  or  tenant,  if  requested  by  the  lessee  or
tenant.  The parties shall mutually agree on the arrangements for the time and manner of the CASp inspection, the payment
of the fee for the CASp inspection, and the cost of making any repairs necessary to correct violations of construction-related
accessibility  standards  within  the  premises.”  In  furtherance  of  the  foregoing,  Landlord  and  Tenant  hereby  agree  as
follows:  (a) any CASp inspection requested by Tenant shall be conducted, at Tenant’s sole cost and expense, by a CASp
designated by Landlord; and (b) pursuant to the terms of Article 13 hereof, Tenant, at its cost, is responsible for making any
repairs within the Premises to correct violations of construction-related accessibility standards; and, if anything done by or
for  Tenant  in  its  use  or  occupancy  of  the  Premises  shall  require  repairs  to  the  Building  (outside  the  Premises)  to  correct
violations of construction-related accessibility standards, then Tenant shall, at Landlord’s option, either perform such repairs
at  Tenant’s  sole  cost  and  expense  or  reimburse  Landlord  upon  demand,  as  additional  rent,  for  the  cost  to  Landlord  of
performing such repairs.

Landlord  and  Tenant  hereby  acknowledge  that  prior  to  the  execution  of  this  Lease,  Landlord  and  Tenant  executed  a
Disability  Access  Obligations  Notice  pursuant  to  San  Francisco  Administrative  Code  Chapter  38.    In  addition,  Tenant
acknowledges  receipt  from  Landlord  of  an  Access  Information  Notice  in  Tenant’s  requested  language  as  required  by  San
Francisco Administrative Code Chapter 38, and Tenant hereby confirms that Tenant’s requested language is English.  Tenant
acknowledges that such notices comply with the requirements of San Francisco Administrative Code Chapter 38.
