Overview

PART I

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

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

At our core, we are antibody-centric and leverage our proprietary G-MAB™ library and targeted delivery modalities to generate the next generation
of cancer therapeutics. Our fully human antibodies include PD-1, PD-L1, CD38, CD47, BCMA, CTLA-4, CD123, CD47, LAG3, ROR1, VEGFR2, CCR2
and CD137 and SARS-CoV-2 neutralizing antibodies, among others. We also have programs assessing the use of our technologies and products in
autoimmune, inflammatory, viral and neurodegenerative diseases.

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

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

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

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

STI-2020, or plutavimab, is a highly potent neutralizing antibody (“nAb”) to COVID-19 that is currently being developed for intranasal (“IN”)
instillation as STI-2099, or COVIDROPS. In preclinical studies, STI-2020/2099 was highly effective against the original Washington strain and early
variants of concern (“VoCs”), including the delta VoC. STI-2020, the intravenous (“IV”) formulation and COVIDROPS were both cleared by the FDA for
Phase I healthy volunteer studies which were completed and demonstrated that the nAbs were well-tolerated (IV up to 200 mg and intranasal up to 60 mg)
without dose limiting toxicity or severe or serious adverse events (“AEs”). Most AEs were mild and unrelated. Phase II studies of COVIDROPS in
outpatients with COVID-19 have begun enrollment in Mexico, the United Kingdom and the U.S. The United Kingdom study reached the planned interim
analysis threshold in the first half of January 2022. The study in Mexico began pediatric enrollment in early 2022. We are also developing a broad-spectrum
neutralizing antibody, STI-9167 (COVISHIELD), to be formulated both for IV and IN administration. STI-9167 (IV formulation) and STI-9199 (IN
formulation using STI-9167 drug substance) have not only been broadly effective in preclinical studies for prior VoCs but are highly potent against the
Omicron VoC. A healthy subject study for STI-9167/9199 is expected to begin in the first quarter of 2022 with Phase II studies of COVISHIELD to follow.

cleared by the FDA and Abivertinib has completed Phase II clinical studies in the U.S. and Brazil of Abivertinib to treat COVID-19-induced acute
respiratory distress syndrome (“ARDS”). While all patient groups improved with treatment, the U.S. study identified an At-Risk population who were the
best responders: those who required oxygen supplementation with non-invasive ventilation or high flow oxygen at baseline. Although the Brazil study did
not enroll a population as sick as those in the U.S. study, the results were similarly supportive. In the U.S. study, the At-Risk patients were discharged on
average two days sooner from the intensive care unit. In both studies, there was nearly a 50% reduction of death and/or mechanical ventilation or
extracorporeal membrane oxygenation by day 29. This data was used to power a pivotal Phase III Abivertinib study which is expected to begin enrollment
in the second quarter of 2022. Two separate Phase II COVI-MSC studies are currently enrolling in Brazil and the U.S. in patients with COVID-19-induced
ARDS. We are also working with Brazilian regulators (ANVISA) to conduct a COVID-19 study with COVI-MSCs in pulmonary long-haul patients post-
recovery from the acute infection.

In furtherance of our goal to enable early detection and treatment across the entire continuum of COVID-19 solutions, we are further developing a

number of highly sensitive and rapid diagnostic tests. COVISTIX™ is a lateral flow antigen test that uses a proprietary platinum-based colloid and
antibody combination, resulting in high sensitivity and accuracy. This is a simple and rapid (15-minute) test with a shallow nasal swab and is designed for
point-of-care and at-home use. This product has been approved under emergency use authorization for use in Mexico and Brazil as a point-of-care test and
has also received its Conformitè Europëenne (“CE”) mark.

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

patients with stage 4, unresectable adenocarcinoma (four with pancreatic cancer and one with colorectal cancer) and CEA-positive liver metastases with
anti-CEA CAR-T. During 2021, we decided to pivot away from an autologous CAR-T platform to allogeneic DAR-T and successfully submitted an
Investigational New Drug application (“IND”) for our CD38 DAR-T candidate for relapsed or refractory multiple myeloma (“RRMM”). We anticipate the
first patient enrollment in the first quarter of 2022.

With respect to Abivertinib for the treatment of non-small cell lung cancer (NSCLC), our oral small molecule combined EGFR/BTK inhibitor, a

final imaging read of Phase III data is pending with additional follow-up from patients who continued on treatment in the years since the last update
presented at the American Society of Clinical Oncology (ASCO) 2019 Annual Meeting. It is anticipated that a pre-new drug application (“NDA”) meeting
will be requested to discuss the pathway to a planned NDA filing. Finally, we intend to start studies in castrate resistant prostate cancer with Abivertinib in
the U.S. in the first quarter of 2022 and in Brazil in the second quarter of 2022.

With respect to our anti-CD38 ADC program, we began enrolling patients in the first quarter of 2021 in a Phase Ib ascending dose study for
systemic Amyloid light-chain (“AL”) amyloidosis. We intend to start a new study to target RRMM in a partnership with Columbia University in the first
quarter of 2022 and are planning collaborations with Columbia to target metastatic esophageal and lung cancer and with MD Anderson to treat T-cell acute
lymphoblastic leukemia (“T-ALL”).

Additionally, based upon our exclusive licensing arrangement with Mayo Clinic for its antibody-drug-nanoparticle albumin-bound (“ADNAB™”)

platform, the next generation in ADC technology, we intend to file several INDs in 2022 to treat various cancer targets. We also have an ongoing
partnership with Mayo Clinic, directed to the use of lymphatic delivery using a hollow core microneedle array device manufactured by our SOFUSA unit,
to explore whether lymphatic delivery of products traditionally delivered by IV administration can improve the pharmacokinetic profile and efficacy while
reducing their AE profile. We also have an active program using the SOFUSA delivery system to treat rheumatoid arthritis patients resistant to etanercept
and expect to announce preliminary results from an ongoing study in the first quarter of 2022.

Broadly speaking, we believe we are among the world’s leading cellular therapy companies today due to our investments in technology and
infrastructure, which have enabled significant progress in developing our next-generation non-viral, “off-the-shelf” allogeneic DAR-T solutions. DAR-T
therapy can become a versatile drug product platform capable of delivering multiple targeted therapeutic approaches.

Outside of immuno-oncology programs, as part of our global aim to provide a wide range of therapeutic products to meet underserved markets, we

have made investments in non-opioid pain management. These include RTX, a non-opioid naturally-occurring product that specifically targets transient
receptor potential vanilloid-1 (“TRPV1”). Depending on the site of injection, RTX can ablate or destroy targeted nerves (e.g., an epidural injection) or
temporarily defunctionalize them (peripheral injections such as intra-articular). TRPV1 largely is responsible for the noxious chronic and inflammatory
pain signaling that can occur post trauma but leaves other nerve functions intact. RTX has been granted orphan drug status for the treatment of intractable
pain with end-stage or advanced cancer and two Phase Ib first-in-human trials (intrathecal and epidural routes) were completed. A Phase Ib trial studying
the safety and efficacy of RTX to treat moderate to severe osteoarthritis (“OA”) knee pain was completed in early 2021 with one year follow-up data and
preliminary results showed the potential for long-term efficacy with no dose-limiting toxicity. We have received clearance to proceed with Phase II clinical
trials of RTX to treat severe cancer pain (epidural) and moderate-to-severe OA of the knee

pain (intra-articular). The knee OA study began enrolling in the fourth quarter of 2021 and the epidural cancer pain study is expected to start enrolling in
the first quarter of 2022.

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

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

Recent Developments

Positive Top-Line Results for Phase III SP-102 Pivotal Trial

In December 2021, Scilex Holding Company announced highly statistically significant positive top-line results from its Phase III SP-102

(SEMDEXA™) Pivotal Trial C.L.E.A.R Program for its novel, non-opioid, corticosteroid formulation, injectable dexamethasone sodium phosphate
viscous gel product for the treatment of lumbosacral radicular pain (sciatica). SP-102 (SEMDEXA™) has received Fast Track status from the FDA.

Enrollment was completed in the second half of 2021. The Pivotal Phase III trial has met the primary efficacy and key secondary efficacy endpoints with
highly statistical significance:

•

For the primary endpoint of change in average daily pain (as measured by the Numeric Pain Rating Scale) in the affected leg over 4 weeks
following the initial injection the LS Mean (SE) group difference of -1.08 (0.17) compared to placebo with a p-value <0.001.

The two key secondary endpoints assessing Oswestry Disability Index (ODI) and Time to open-label repeat injection have also demonstrated
highly statistically significant results for SP-102. The LS Mean (SE) group difference in ODI compared to placebo at week 4 was -6.28
(1.49) with a p-value <0.001. A Cox proportional hazard model showed significantly longer duration of initial SP-102 (SEMDEXA™)
treatment compared to placebo Hazard Ratio (95% CI) 0.49 (0.36, 0.65), with a p-value <0.001.

Virex Acquisition

On February 1, 2022, we completed the acquisition of Virex Health, Inc. (“Virex”) pursuant to that certain Agreement and Plan of Merger (the

“Virex Merger Agreement”), dated as of January 14, 2022, among us, Virex, VH Merger Sub I, Inc., our wholly owned subsidiary (“Merger Sub”), VH
Merger Sub II, LLC, our wholly owned subsidiary (“Merger LLC”), and Fortis Advisors LLC, as representative of the equityholders of Virex (the
“Stockholders’ Representative”). Pursuant to the terms of the Merger Agreement, Merger Sub was merged with and into Virex (the “Initial Merger”), with
Virex continuing as the surviving corporation in such merger, and subsequent to the Initial Merger, Virex was merged with and into Merger LLC (the
“Subsequent Merger”), with Merger LLC surviving as our wholly owned subsidiary. At the effective time of the Subsequent Merger, the name of Merger
LLC as the surviving company in the Subsequent Merger was changed to Virex Health, LLC.

Upon completion of the Initial Merger, the equityholders of Virex (the “Virex Equityholders”) became entitled to receive the following amounts (to

be paid in cash and stock as further described below): (i) $12,000,000, as such amount was adjusted to $11,566,275 (and may be further adjusted post-
closing) pursuant to the terms of the Virex Merger Agreement for indebtedness, transaction expenses and cash (the “Closing Consideration”) and (ii)
subject to achievement of certain regulatory milestones, up to $10,000,000 in additional consideration (the “Milestone Payment” and together with the
Closing Consideration, the “Merger Consideration”).

Pursuant to the Merger Agreement, the Merger Consideration shall be paid as follows: (i) 59% in cash; and (ii) 41% in shares of our common stock.

Upon completion of the Initial Merger, the Virex Equityholders became entitled to receive an aggregate of $6,824,126 in cash and an aggregate of
1,281,662 shares of our common stock based on a price per share equal to $3.70 (representing the volume weighted average closing price per share of our
common stock for the eleven consecutive trading days ending on the date that was three trading days prior to the closing date). Ten percent of the Closing
Consideration was deposited into an escrow account (in the form of cash and stock) as partial security for the indemnification obligations of the Virex
Equityholders under the Merger Agreement and $150,000 was set aside for expenses that may be incurred by the Stockholders’ Representative.

At any time shares of our common stock are issued in respect of a Milestone Payment, the number of shares to be issued will be based on a price per

share equal to the volume weighted average closing price per share of our common stock for the eleven

consecutive trading days ending on the date that is three trading days prior to the applicable issuance date. The aggregate number of shares of our common
stock issuable pursuant to the Virex Merger Agreement as Merger Consideration shall not exceed 19.99% of the total number of shares of our common
stock issued and outstanding at the closing date.

Our Strategy

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

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

Our core strategic objectives and resources are:

1. Using a deliberate process to optimize our lead product candidates to fill identified unmet needs and advance them rapidly into the clinic for
initiation of Phase I studies. Once demonstrated to be safe and efficacious, we plan to continue to drive through later phase (II and III) studies toward a
NDA filing. Early in this process, we evaluate each program for potential accelerated approval or breakthrough therapy designation to fast-track
development.

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

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

3. Having active programs that utilize our antibodies for DAR-T, our antibody-drug conjugate platform (using our covalent linker technology),

ADNAB platform, and our SOFUSA® DoseConnect™ lymphatic delivery device to treat various oncology indications. Additionally, we have active
programs to treat the spectrum of COVID-19 infections with our highly potent neutralizing antibodies (“nAbs”) to treat outpatients with mild COVID-19
symptoms (IV COVI-AMG and intranasal COVIDROPS™) and hospitalized patients with moderate respiratory compromise (Abivertinib) or with severe
ARDS (COVI-MSC). We are also developing a broad-spectrum neutralizing antibody, STI-9167 (IV) / STI-9199 (IN) (COVISHIELD), to treat outpatients
with mild symptoms and for post-exposure prophylaxis. Finally, we continue to progress RTX, an ultrapotent TRPV-1 agonist, into Phase III for the
treatment of intractable pain in advanced cancer and moderate-to-severe knee osteoarthritis. Our subsidiary, Scilex Holding, is working towards an NDA
submission for SP-102 (SEMDEXA) in the treatment of lumbar radiculopathy.

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

generating data to support more than a dozen new INDs in 2022. These include moving our checkpoint inhibitors from our core antibody portfolio into the
clinic with our strategic key opinion leaders and institutional partners. We will continue to develop our fully human monoclonal antibody (“mAb”)
portfolio for new ADCs and bispecific mAbs. In addition, we expect to commence several clinical trials with our SOFUSA device to explore the safety and
efficacy features of this innovative drug delivery technology.

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

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

6. Continuing strategic partnerships to share in the risk reward of our core franchises and to derive near term value from our non-core programs. Our

partnering objectives include generating revenue through license fees, milestone-related development fees and royalties as well as profit shares or joint
ventures to generate potential returns from our product candidates and technologies.

Segment Information

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

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

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

moderate to severe osteoarthritis of the knee pain. This segment further includes the full suite of COVID-19 treatments, diagnostics and vaccines under
development, including COVIDROPS, COVISHIELD, COVI-MSC, COVISTIX and COVITRACK.

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

segment are exclusively derived from the sale of ZTlido.

Clinical Programs

G-MAB™: Fully Human Antibody Library Platform

Our G-MAB library (“G-MAB”), which forms the backbone of many of our product candidates, was initially invented by Henry Ji, Ph.D., our co-
founder, President and Chief Executive Officer. We believe our proprietary G-MAB library is one of the industry’s largest and most diverse fully human
antibody libraries, with an estimated one quadrillion unique antibodies available for drug discovery and development. We believe G-MAB may offer the
following advantages over competing antibody libraries:

•

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

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

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

Our objective is to leverage G-MAB to develop first-in-class or best-in-class antibody drug candidates that will possess greater efficacy and fewer
side effects as compared to existing drugs and develop them as novel monotherapies (PD-L1, CD47), ADCs (CD38), components of bispecific antibodies,
and as part of our adoptive immunotherapy (CD38, BCMA), oncolytic virus program (Seprehvec) and intracellular targeting programs (STAT3, mutant
KRAS).

To date, we have screened over 100 validated targets and generated a number of fully human antibodies against these targets which are at various
stages of development. These include PD-1, PD-L1, CD38, CD47, BCMA, CTLA-4, CD123, CD47, LAG3, ROR1,VEGFR2, CCR2 and CD137 among
others. Upon the completion of preclinical studies, our objective is to, independently or in tandem with our strategic collaborators, file INDs for these
product candidates.

COVID-19 (SARS-CoV-2)

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

requiring hospitalization, including progression to ARDS and its associated high mortality rate due to a virus-induced hyperinflammatory response or
“cytokine storm”. Patients with COVID-19 may develop elevated blood levels of multiple inflammatory cytokines and chemokines and those who are
admitted to intensive care have even higher levels of these cytokines, which may indicate a far worse outcome.

We have leveraged our expertise in producing fully human monoclonal antibodies and our extensive G-MAB antibody library to develop potent

neutralizing antibodies directed to the spike protein of SARS-CoV-2 or COVID-19. In addition, we have acquired or licensed assets that target the entire
spectrum of COVID-19 infections, from outpatients who are asymptomatic or with mild symptoms to hospitalized patients with moderate symptoms to
patients with severe or critical COVID-19 in intensive care units. Paired with our highly sensitive and specific diagnostic tests for COVID-19 in
development, we have developed the ability to diagnose early and effectively treat every stage of this pandemic infection.

COVISTIX is a lateral flow rapid diagnostic test that offers early and accurate SARS-CoV-2 detection and treatment to not only protect the
population, but also to facilitate early treatment, resulting in improved outcomes for patients who become infected. Using Sorrento’s unique capability to
rapidly screen and develop highly potent antibodies, we developed COVISTIX, a highly sensitive 15-minute antigen test for detection of the SARS-CoV-2
virus. The test uses a proprietary platinum nano-catalyst core (“PtNC”) plus 2 antibody combination which yields up to 100-fold increases in sensitivity
over conventional lateral flow colloidal gold assays. COVISTIX has also demonstrated high sensitivity across all variants, including Omicron, and
maintained its sensitivity even in an all-comers (asymptomatic and symptomatic) patient population. This technology is ideally suited for either rapid point-
of-care testing or at-home use. COVISTIX has been EUA cleared in, and is being marketed in, Mexico (COFEPRIS) and Brazil (ANVISA), and is CE-
marked in Europe for IVD professional point-of-care use. EUA submissions have been completed and we are awaiting regulatory clearance from WHO,
Canada (Health Canada), and the FDA.

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

be effective against the original Wuhan, China COVID-19 strain and the delta VoC. STI-2020, formulated for intravenous administration, blocks viral
interactions with the ACE-2 receptor to prevent cell entry and replication and was engineered to lack any antibody-dependent enhancement (“ADE”) and
tissue cross-reactivity (including possible hypersensitivity), neither of which has been observed in in vitro or in vivo preclinical studies. In the Syrian
Golden hamster model, intravenous STI-2020 rapidly reversed COVID-19 infection and cleared viral particles from lung tissues. After a successful IND
submission, intravenous STI-2020 (administered as a slow intravenous push) completed a healthy subject study demonstrating a benign safety profile.
Further development of STI-2020 was deferred in favor of STI-2099 (COVIDROPS).

STI-2099 (COVIDROPS) is STI-2020 formulated for intranasal delivery. The neutralizing potency of STI-2020 lends itself to intranasal delivery,

which may be an effective way of rapidly reducing infectivity and clearing viral burden from the nasopharynx and lung airways. STI-2099 may be a
preferred treatment for children who may not be willing to receive an injection. After a successful IND clearance, we completed a healthy subject study
demonstrating a benign safety profile for intranasal STI-2099. Phase II studies have begun in the U.S., United Kingdom and Mexico to demonstrate proof-
of-concept. The U.S. study was completed early in the first quarter of 2022 and the UK study reached its interim analysis threshold (50% enrollment) early
in the first quarter of 2022.

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

(“EGFR”) and, importantly, also a BTK receptor. It inhibits the gatekeeper mutation of EGFR; T790M, as well as the common activating mutations
(L858R, 19del), and has minimal inhibitory activity against the wild type (“WT”) receptor, contributing to its observed safety. Additionally, STI-5656
irreversibly binds to the BTK receptor at nanomolar potency, preventing the phosphorylation of the receptor and has shown potent immunomodulatory
activities by inhibiting key pro-inflammatory cytokine production, including IL-1beta, IL-6 and TNF-alpha, all of which are correlated with higher
morbidity and mortality in ARDS and “cytokine storm” due to COVID-19 infections. STI-5656 has completed enrollment in two Phase II studies in the
U.S. and Brazil in subjects with COVID-19-induced respiratory compromise. These studies identified an “At-Risk” population likely to respond to
treatment with STI-5656, those requiring non-invasive ventilation or high flow oxygen supplementation for which no treatments other than supportive care
are available. A pivotal study is planned for 2022.

STI-8282(COVI-MSC): After acquiring an allogeneic culture-expanded adipose-derived mesenchymal stem cell (“MSC”) asset from Personalized
Stem Cells, Inc., we transitioned the open IND and completed a Phase Ib single site (Fresno, CA) study of subjects with severe COVID-19 infections and
acute respiratory failure or frank ARDS who received up to three infusions of STI-8282. In this study, all 10 subjects enrolled were able to be discharged
from the hospital within several days of treatment. Phase II studies in the U.S. and Brazil started enrollment in the fourth quarter of 2021 and are expected
to be completed in the first or second quarter of 2022.

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

September 2020 gave us the ability to use non-viral DNA and RNA gene delivery platforms to create a gene-encoded therapeutic product candidate using
our STI-2020 neutralizing antibody. With this combination, an intramuscular injection can cause a person’s own body to produce the neutralizing antibody,
for possibly months, instead of having to rely on intermittent injections of externally manufactured antibodies, such as STI-2020. STI-8472 is the
combination of the non-viral DNA plasmid with gene-encoded STI-2020. We are in the process of completing the IND-enabling preclinical and chemistry,
manufacturing and controls steps necessary to file an IND in 2022. We envision a combination of an STI-2020 injection to “treat” and STI-8472 to
“prevent” reinfection in those positive for COVID-19, or in subjects negative for COVID-19, to prevent infection. This may be a valuable option for those
who cannot or refuse to be vaccinated for health or other reasons. This program received approved funding from the Defense Advanced Research Projects
Agency (“DARPA”), an advanced-technology branch of the U.S. Department of Defense.

Anti-CD38 CAR-T Program

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

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

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

from most mature resting lymphocytes, with the notable exception of terminally differentiated plasma cells. Because CD38 is highly expressed on multiple
myeloma cells, it represents a valuable and validated therapeutic target against myeloma. Multiple myeloma is a hematologic malignancy in which clonal
plasma cells accumulate in the bone marrow or extramedullary sites and give rise to clinical complications such as painful, lytic bone lesions,
hypercalcemia, renal impairment, cytopenias, and symptomatic plasmacytomas.

STI-2798 and STI-5171 (anti-CD38 CAR-T): Our proprietary, second generation anti-CD38 CAR-T therapy was being developed for the
treatment of RRMM. Our anti-CD38 CAR-T is based on a fully human anti-CD38 monoclonal antibody derived from our G-MAB antibody library. We
completed a Phase Ib ascending dose safety study of STI-5171, which began in 2018 with the initial anti-CD38 CAR-T platform. While long-term follow
up is continuing, in the last two dose cohorts (106 or 107 cells/kg body weight), we achieved a 50% overall response rate. We improved on the CAR-T
construct by removing the “myc tag” (which cannot be used in Europe) from the CAR-T product candidate (STI-2798) and made changes to the
lymphodepletion protocol in hopes of improving long-term cell persistence. We completed a successful IND submission for STI-2798, our new anti-CD38
CAR-T (-myc), for subjects with RRMM but elected to pivot to our new allogeneic anti-CD38 knock-out/knock-in (“KOKI”) DAR-T (STI-1492).

Anti-CD38 KOKI DAR-T Program

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

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

STI-1492 (anti-CD38 DAR-T) is an allogeneic non-viral anti-CD38 A2 KOKI DAR-T cell agent (second generation anti-CD38 “knock-out knock-
in” dimeric antigen receptor 4-1BBζ - engineered T cells), which is IND-cleared and is pending enrollment. STI-1492 consists of allogeneic donor T cells
that are engineered to express an anti-CD38 antigen receptor for the treatment of patients with RRMM. The DAR consists of a Fab variable region instead
of the scFv utilized by CARs. During the production of STI-1492, there is a “knock-in” of the DAR into the T-cell receptor (“TCR”) alpha constant region
(“TRAC”) gene. The TCR alpha is simultaneously inactivated (“knock-out”) by this DAR knock-in process, allowing allogeneic T cells to be administered
therapeutically without the development of graft versus host disease. In addition, STI-1492 utilizes a 4-1BB co-stimulatory domain. The anti-CD38 DAR
design is associated with enhanced cytotoxic activity, longer persistence and potentially less toxicity compared with the anti-CD38 CAR design in
preclinical studies. The ability to administer this agent as modified allogeneic T cells allows STI-1492 to be stored as an off-the-shelf agent that eliminates
the need for leukapheresis and the treatment delay for the manufacturing process for each individual patient associated with autologous cellular therapy.

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

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

•

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

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

applicability to both autologous and allogeneic cellular therapies.

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

Anti-CD38 Antibody-Drug Conjugate (ADC) Program

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

STI-6129 (anti-CD38 ADC) is composed of a human monoclonal anti-CD38 A2 antibody (STI-5171) covalently bound by a chemical linker to a

dolastatin tubulin inhibitor chemotherapeutic derivative (duostatin 5.2). STI-5171 was generated from Sorrento’s proprietary G-MAB antibody library. The
binding affinity of STI-5171 to CD38 is comparable to that of daratumumab but it binds to different epitopes (Sorrento data on file). The STI-6129 ADC is
produced by conjugation of the drug-linker-duostatin moiety to the parent STI-5171 monoclonal antibody. The heavy chain of the STI-5171 parent
antibody included in the STI-6129 ADC has been modified by a C246→S mutation that substitutes a serine amino acid for cysteine. This substitution
results in an antibody with 3 inter-chain disulfide bonds instead of the 4 disulfide bonds present in wild type IgG1 antibodies and provides an ADC with
drug to antibody ratio of 3 (Sorrento data on file). Upon binding to CD38 target cell surface antigen, the STI-6129 ADC is internalized by the cell and
undergoes lysosomal degradation resulting in the release of the duostatin 5.2 chemotherapeutic agent. This targeted delivery of potent chemotherapeutic
agents is designed to enhance activity against the aberrant plasma cells in AL amyloidosis, minimize toxicity in normal tissues, and provide sustained
delivery of the chemotherapy over time. The proprietary stable covalent linker technology reduces premature systemic release of duostatin, which may
reduce or eliminate ocular toxicity and other adverse events. After a successful IND submission, STI-6129 is currently enrolling patients in an ascending
dose study to identify the maximum tolerated dose to be used for the treatment of AL amyloidosis. To date, no ocular toxicity has been observed. Once a
recommended Phase II dose is identified, an expansion cohort will be enrolled. Additionally, we are partnering with Columbia University in New York City
to assess STI-6129 in the treatment of RRMM and metastatic esophageal cancer, and with MD Anderson to assess STI-6129 in the treatment of T-ALL.

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

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

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

STI-6643 (anti-CD47 antibody) is our novel fully human CD47 monoclonal antibody that blocks CD47/SIRPα to promote in vitro anti-tumor

phagocytic activity. When incubated with human peripheral blood mononuclear cells in a mixed lymphocyte reaction assay, STI-6643 demonstrated
minimal T, B or NK cell depletion as opposed to reference clones (prepared based on sequence

analysis) which could result in improved efficacy by preserving the infiltrating anti-tumor immune cells. Additionally, STI-6643 showed 15- to 30-fold
reduction in observed hemagglutination in human and cynomolgus monkey red blood cells, respectively, and despite its high binding to canine red blood
cells, it showed reduced hemagglutination in comparison to magrolimab (clone prepared based on the sequence analysis). After a successful IND
submission, the Phase Ib study has begun enrollment.

Antibody-Drug Nanoparticle Albumin Bound (ADNAB) Platform

We have partnered with Svetomir Markovic, MD, Ph.D. at Mayo Clinic Rochester to use the nanoparticle human serum albumin bound paclitaxel

(or other chemotherapeutic agents) platform to bind various monoclonal antibodies to the external surface of the albumin micelles to form stable complexes
that can be designed to target specific cancers for delivery directly to the tumor microenvironment. This partnership would leverage our existing antibody
library, PD-1, PD-L1, CD38, CD47, BCMA, CTLA-4, CD123, CD47, LAG3, ROR1, VEGFR2, CCR2 and CD137, among others, to create ADNAB
products that may enhance tumor response. The first programs (B cell lymphomas, melanoma and gynecological cancers) are already ongoing under
investigator-initiated INDs that we support. We intend to use our PD-L1 (STI-3031) mAb in an investigator-initiated IND submission in the second quarter
of 2022.

SOFUSA® Lymphatic Delivery System (S-LDS)

SOFUSA is a novel technology platform designed for targeted drug delivery to lymphatics vessels and lymph nodes. Abnormal immune system

function is implicated in many conditions such as cancer and autoimmune diseases (e.g., rheumatoid arthritis, multiple sclerosis and psoriasis). SOFUSA’s
proprietary nanotopography draped microneedles have been shown to reversibly open tight junctions in the skin and facilitate paracellular and transcellular
transport across the epidermis. In preclinical biodistribution studies, this proprietary microneedle and microfluidics system has consistently demonstrated
the ability to deliver over 40-fold in drug concentration to lymph nodes (with lower drug concentration in systemic organs) when compared to traditional
IV and subcutaneous (“SC”) injections. For drugs that target the immune system, SOFUSA offers the potential to achieve a superior clinical response with
potentially lower doses and/or side effects versus systemic injections or infusions.

Phase I clinical safety studies have now been completed, and two Phase 1b studies are underway to evaluate safety and pilot efficacy in our first
human proof of concept studies. The first study is in autoimmune diseases with an anti-TNFα in rheumatoid arthritis (“RA”) and the second study in cancer
with a checkpoint inhibitor (anti-PD-1) in cutaneous T-cell lymphoma (“CTCL”). Early results are quite promising in the RA study in that the first four
patients who were non-responders to full dose subcutaneous injections were switched to a 50% dose using SOFUSA, and all patients showed Disease
Activity Score (“DAS”) improvement. The first patient has completed the 12-week study and demonstrated an approximately 40% improvement in DAS
and a 91% improvement in tender joints (from 11 tender joints to one). The study is now 50% enrolled and should be completed in the second quarter of
2022. The anti-PD-1 CTCL study is expected to start in the first quarter of 2022. We are also conducting multiple intention-to-treat studies to explore
additional drugs (anti-CTLA-4) and indications (e.g., melanoma and non-Hodgkin’s lymphoma).

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

volume peptides and vaccines. The skin (rich in dendritic cells) and lymph nodes are the primary organs for generating both humoral immunity (IgG and
IgM) and cellular immunity (memory T-Cells) for long-term protection. In a preclinical study using a model Ovalbumin (“OVA”) protein antigen,
SOFUSA MuVaxx demonstrated a 60-100 fold increase in anti-OVA IgG antibodies vs intramuscular (“IM”) injections, and in another preclinical COVID-
19 vaccine study, the SOFUSA device resulted in 10-40X higher T-Cell response versus IM and intradermal injections. The SOFUSA MuVaxx device is
designed to be a simple low-cost attachment to a standard syringe for rapid large-scale deployment of our vaccine candidates and, due to the small needle
size, is expected to result in a pain-free injection.

Oncolytic Virus Program (Seprehvir® and Seprehvec®)

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

or young adult non-central nervous system tumors or malignant pleural mesothelioma with intratumoral, intravenous or intrapleural administration. A
second-generation product, STI-1386 (Seprehvec), is a platform that can generate a number of possible product candidates. We successfully completed an
IND submission in the fourth quarter of 2021 and are expecting enrollment to begin in the first quarter of 2022, targeting pancreatic cancer, soft tissue
sarcomas and hepatic metastases.

Resiniferatoxin (“RTX”) Programs

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

An investigator-sponsored Phase I clinical trial of intrathecal RTX has been ongoing at the NIH under a Cooperative Research and Development
Agreement. To date, 16 patients with terminal cancer pain have been treated intrathecally at the NIH. Additional enrollment in this study is planned for
2022.

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

toxicity was observed at doses up to 25 mcg RTX and RTX demonstrated promising efficacy in relieving intractable pain associated with advanced cancer.
A Phase II study was cleared to proceed and enrollment is expected to commence in the second quarter of 2022.

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

limiting toxicities at any of the administered doses. A total of 94 patients were enrolled at RTX doses from 5 mcg to 25 mcg; 40 subjects enrolled in the
placebo-controlled ascending dose portion of the study; 38 subjects received 12.5 mcg and 16 subjects received 25 mcg. The preliminary efficacy results in
this study showed promising evidence of a significant improvement lasting well beyond six months. A Phase II study was cleared to proceed and began
enrolling in the fourth quarter of 2021. It is expected to fully enroll in mid-2022 with one year follow up to provide clarity on long-term safety and efficacy.

Scilex Holding

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

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

ZTlido

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

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

We launched ZTlido in October 2018 with support from an integrated commercial organization using a dedicated contract sales force and our own

sales management, marketing and managed care capabilities. We currently market ZTlido through a dedicated sales force of 60 individuals, targeting
approximately 10,000 primary care physicians, pain specialists, neurologists and palliative care physicians. We are utilizing a multi-channel marketing
strategy to expand awareness and utilization of ZTlido. There is coverage for ZTlido from national and regional pharmacy benefit managers, health
maintenance organizations, Medicare and Medicaid plans for approximately 165 million covered lives.

SEMDEXA

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

to address the serious risks posed by off-label epidural steroid injections (“ESIs”) for the treatment of sciatica, a pathology of low back pain. We believe
SEMDEXA, if successfully developed, has the potential to reduce the disability related to sciatica and help delay or avoid spine surgery. SEMDEXA has
been granted fast track designation by the FDA and, if approved, could become the only FDA-approved alternative to off-label ESIs, which are
administered over 10 million times annually in the United States. Enrollment for the Phase III trial was completed in the second half of 2021. We
announced top-line data from this study in December 2021. The SP-102 pivotal Phase III trial 12-week data demonstrated a highly statistically significant
greater effect over placebo for primary and secondary endpoints with no safety risks identified. The complete six-months data analysis is expected by
March 2022. Based on the current results, we plan to submit a request to the FDA for Breakthrough Therapy Designation, which will help expedite the
overall development program and potential market approval. We also expect to submit a pre-NDA meeting request to the FDA in the first half of 2022.

SP-103

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

the learnings from ZTlido because both products share a similar adhesive drug delivery formulation and manufacturing technology. If approved, we believe
that SP-103 could become the first-in-class lidocaine topical product for low back pain indications. All current uses of topical lidocaine products for low
back pain are off-label. SP-103 has three times the drug load of ZTlido (108 mg versus 36 mg) in the adhesive system to potentially deliver threefold level
of the drug within a targeted area, still with

the convenience of a single topical system. Additionally, SP-103 is designed to deliver a localized dose of lidocaine that is threefold greater than any
lidocaine topical product that we are aware of either on the market or in development. If approved, we believe SP-103 may be able to address the
limitations of prescription lidocaine patches in treating low back pain by delivering a higher dose of lidocaine to the application site. We expect the Phase II
trial to commence in the first half of 2022.

SP-104

We are developing SP-104, a novel low-dose delayed-release naltrexone hydrochloride formulation for the treatment of fibromyalgia. Fibromyalgia
is considered a neurosensory disorder characterized in part by abnormalities in pain processing by the central nervous system. Increased understanding of
the biological bases underlying fibromyalgia is rapidly leading to a new era of specific pharmacologic therapy for the condition. Fibromyalgia affects
approximately ~3-6% of the adult population. There are estimated to be between 8-10 million individuals with fibromyalgia in the United States.
Fibromyalgia is the second most common disorder that rheumatologists encounter, as it is seen in 15% of evaluated patients. Approximately 8% of patients
cared for in primary care clinics have fibromyalgia. Women have a higher frequency of fibromyalgia. Prominent fibromyalgia researchers and specialists
estimate the costs in the U.S. to be between $12-14 billion each year and it accounts for a loss of 1-2% of the national overall productivity. Current FDA-
approved treatments for fibromyalgia include duloxetine, pregabalin, and milnacipran. Despite the availability of these treatments, there is a large unmet
need in the marketplace as these treatments have response rates of less than 50%, ranging from 27 to 40%. Two Phase I studies are ongoing and are
designed to characterize the pharmacokinetics (PK) of SP-104 and the safety of SP-104 relative to the known naltrexone adverse effects. We plan to initiate
a Phase II clinical trial in the second half of 2022.

designed to deliver large molecules, such as antibodies, directly into lymphatic capillaries and tumor draining lymph nodes. This micro-epidermal
infusion system features a proprietary microneedle array and microfluidics reservoir. The SOFUSA technology is the subject of multiple granted and
pending applications with potential patent coverage to at least 2040.

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

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

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

Competition

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

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

collaborative partners, operate larger research and development programs, and have substantially greater commercial and financial resources than we do, as
well as significantly greater experience in: developing product candidates and technologies, undertaking preclinical studies and clinical trials, obtaining
FDA and other regulatory approvals of product candidates, formulating

and manufacturing product candidates and launching, marketing and selling product candidates. As a result, these companies may obtain marketing
approval more rapidly than we are able and may be more effective in developing, selling and marketing their products.

Immunotherapy

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

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

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

RTX

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

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

COVID-19 Product Candidates

Neutralizing antibodies (“nAbs”): We have several nAbs either in development or in the clinic. These nAbs are directed against the COVID-19 spike
protein and have varying degrees of effectiveness dependent on the VoC being targeted. The lead nAb during 2021, STI-2020, was shown to be effective in
preclinical studies against the original Washington strain as well as the delta VoC. With the meteoric rise of the omicron VoC late in 2021, we identified a
new highly potent nAb, STI-9167, which we initially obtained under an exclusive license from Mount Sinai and modified to be a fully-human nAb with
modifications to reduce the potential for antibody-dependent enhancement or human tissue cross-reactivity. This nAb is highly effective in preclinical
studies against Omicron and Omicron plus and we filed an IND early in the first quarter of 2022 to begin human safety studies of both the IV and intranasal
formulations. There are several other companies which have nAbs in early development. In addition, companies that are involved in vaccine development
are indirect competitors in this space, although the vaccines approved to date and known to be in development are not nAbs-based.

Bruton’s Tyrosine Kinase Inhibitors (“BTKi”): We have completed Phase II trials with Abivertinib, our dual EGFR/BTKi, to treat ARD due to

COVID-19. There are several other BTKis approved for oncology conditions that could theoretically be used to treat COVID-19-induced ARD. For
example, Acalabrutinib (Calquence) was used in two Phase II studies but failed to meet its primary endpoint.

Adipose-derived mesenchymal stromal or stem cells (AdMSCs): We are currently enrolling two Phase II studies treating COVID-19-induced ARD

and ARDS in the U.S. and Brazil. There are a large number of companies and universities exploring various MSCs (adipose, bone marrow, cord blood,
umbilical and other sources) in Phase I and II studies to treat moderate to severe COVID-19.

Scilex

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

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

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

The key competitive factors affecting the success of ZTlido, SEMDEXA, SP-103 and SP-104 are likely to be their efficacy, durability, safety, price

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

Government Regulation

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

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

U.S. Government Regulations

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

•

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

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

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

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

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

•

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

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

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

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

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

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

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

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

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

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

•

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

•

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

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

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

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

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

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

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

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

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

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

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

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

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

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

approved BLA or NDA, we would be required to report, among other things, certain adverse reactions and production problems to the FDA, to provide
updated safety and efficacy information, and to comply with requirements concerning advertising and promotional labeling for any of our products. Also,
quality control and manufacturing procedures must continue to conform to cGMP after approval to ensure and preserve the long term stability of the drug
product. The FDA periodically (about every two years) inspects manufacturing facilities to assess compliance with cGMP, which imposes extensive
procedural, substantive and record keeping requirements. In addition, changes to the manufacturing process are strictly regulated, and, depending on the
significance of the change, may require prior FDA approval before being implemented. FDA regulations also require investigation and correction of any
deviations from cGMP and impose reporting and documentation requirements upon us and any third-party manufacturers that we may decide to use.
Accordingly, manufacturers must continue to expend time, money and effort in the area of production and quality control to maintain compliance with
cGMP and other aspects of regulatory compliance.

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

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

Europe/Rest of World Government Regulations

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

trials and any commercial sales and distribution of our products.

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

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

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

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

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

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

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

Available Special Regulatory Procedures

Formal Meetings

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

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

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

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

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

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

Orphan Drug Designation

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

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

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

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

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

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

Authorization Procedures in the European Union

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

•

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

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

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

•

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

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

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

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

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

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

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

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

trials or receive any regulatory approvals.

Pharmaceutical Coverage, Pricing and Reimbursement

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

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

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

•

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

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

•

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

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

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

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

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

Other Healthcare Laws and Compliance Requirements

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

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

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

The federal False Claims Act imposes liability on any person who, among other things, knowingly presents, or causes to be presented, a false or
fraudulent claim for payment by a federal healthcare program. The “qui tam” provisions of the False Claims Act allow a private individual to bring civil
actions on behalf of the federal government alleging that the defendant has submitted a false claim to the federal government, and to share in any monetary
recovery. In addition, various states have enacted false claims laws analogous to the False Claims Act. Many of these state laws apply where a claim is
submitted to any third-party payer and not merely a federal healthcare program. When an entity is determined to have violated the False Claims Act, it may
be required to pay up to three times the actual damages sustained by the government, plus civil penalties of $11,803 to $23,607 (each subject to adjustment
for inflation) for each separate false claim.

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

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

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

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

Antibody Clinical Development

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

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

Marketing and Sales

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

Manufacturing and Raw Materials

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

some of our product candidates. We may or may not manufacture the products we develop, if any. As of December 31, 2021, our ZTlido product is
manufactured by ITOCHU CHEMICAL FRONTIER Corporation. Our internal manufacturing and contract manufacturers are subject to extensive
governmental regulation. Regulatory authorities in our markets require that pharmaceutical products be manufactured, packaged and labeled in conformity
with cGMPs. We have established a quality control and quality assurance program, which includes a set of standard operating procedures and specifications
designed to ensure that our products are manufactured in accordance with cGMPs, and other applicable domestic and foreign regulations.

Employees

As of December 31, 2021, we had 799 employees and 22 consultants and advisors. A significant number of our management and our other

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

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

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

Corporate Information

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

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

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

Item 1A. Risk Factors.

Risk Factor Summary

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

•

We are a clinical and commercial stage company subject to significant risks and uncertainties, including the risk that we or our partners may
fail to develop, obtain regulatory approval or market our product candidates or generate product related revenues.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

•

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

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

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

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

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

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

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

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

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

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

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

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

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

Our strategic investments may result in losses.

Risks Related to Our Financial Position and Capital Requirements

We are a clinical and commercial stage company subject to significant risks and uncertainties, including the risk that we or our partners may fail to
develop, obtain regulatory approval or market our product candidates or generate product related revenues.

We are primarily a clinical and commercial stage biotechnology company that began operating and commenced research and development activities

in 2009. Pharmaceutical product development is a highly speculative undertaking and involves a substantial degree of risk. There is no assurance that our
libraries of fully-human mAbs or any of our other product candidates in development will be suitable for diagnostic or therapeutic use, or that we will be
able to identify and isolate therapeutic product candidates, or develop, market and commercialize these candidates. We do not expect any of our product
candidates in development, including, but not limited to, our fully human mAbs derived from our proprietary G-MAB library platform (e.g., PD-L1,
CD47), antibody drug conjugates (“ADCs”), bispecific antibodies (“BsAbs”), as well as Chimeric Antigen Receptor T Cells (“CAR-T”) and Dimeric
Antigen Receptor T Cells (“DAR-T”) for adoptive cellular immunotherapy, resiniferatoxin (“RTX”), higher strength lidocaine topical system (SP-103),
non-opioid corticosteroid formulated as a viscous gel injection (SP-102) (“SEMDEXATM”) and lymphatic drug delivery system (SOFUSA) to be
commercially available for a few years, if at all. Additionally, our COVID-19 related product candidates, including STI-2020 (affinity matured neutralizing
antibody; COVI-AMG), STI-2099 (intranasal affinity matured neutralizing antibody; COVIDROPS), STI-9167 (broad-spectrum neutralizing antibody;
COVISHIELD), STI-5656 (Abivertinib), STI-8282 (allogeneic adipose-derived mesenchymal stem cells; COVI-MSC), serological IgM/IgG antibody
diagnostic test (COVITRACK) and lateral flow viral antigen diagnostic test for SARS-CoV-2 (COVISTIX), are subject to uncertainties relating to product
development, regulatory approval and commercialization, and further risks based on the constantly evolving situation affecting the United States and the
international community. Even if we are able to commercialize our product candidates, there is no assurance that these candidates would generate revenues
or that any revenues generated would be sufficient for us to become profitable or thereafter maintain profitability.

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

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

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

As of December 31, 2021 and 2020, we had an accumulated deficit of $1,386.6 million and $958.3 million, respectively. We continue to incur

significant research and development and other expenses related to our ongoing operations. We have incurred operating losses since our inception, expect
to continue to incur significant operating losses for the foreseeable future, and we expect these losses to increase as we: (i) advance RTX, STI-6129 (anti-
CD38 ADC), STI-1492 (anti-CD38 DAR-T), STI-6643 (anti-CD47 antibody), SP-103, SEMDEXATM and our other product candidates, including our
COVID-19 related product candidates, STI-2099 (COVIDROPS), STI-9167 (COVISHIELD), STI-8282 (COVI-MSC) and STI-5656 (Abivertinib), into
further clinical trials and pursue other development, acquire, develop and manufacture clinical trial materials and increase other regulatory operating
activities, (ii) conduct further studies for our preclinical COVID-19 related product candidates to advance to clinical trials and seek regulatory approval;
(iii) incur incremental expenses associated with our efforts to further advance a number of potential product candidates into preclinical development
activities, (iv) continue to identify and advance a number of fully human therapeutic antibody and ADC preclinical product candidates, (v) incur higher
salary, lab supply and infrastructure costs incurred in connection with supporting all of our programs, (vi) invest in our joint ventures, collaborations or
other third party agreements, (vii) incur expenses in conjunction with defending and enforcing our rights in various litigation matters, (viii) expand our
corporate, development and manufacturing infrastructure, and (ix) support our subsidiaries, including Bioserv Corporation, Levena Biopharma US Inc.,
Scilex Holding Company (“Scilex Holding”) and SmartPharm Therapeutics, Inc., in their clinical trial, development and commercialization efforts. As
such, we are subject to all risks incidental to the development of new biopharmaceutical products and related companion diagnostics, and we may
encounter unforeseen expenses, difficulties, complications, delays and other unknown factors that may adversely affect our business. Our prior losses,
combined with expected future losses, have had and will continue to have an adverse effect on our stockholders’ equity and working capital.

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

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

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

uncertainty regarding our ability to maintain liquidity sufficient to operate our business effectively, which raises substantial doubt about our ability to
continue as a going concern. If we are unsuccessful in our efforts to raise outside financing, we may be required to significantly reduce or cease operations.
The report of our independent registered public accounting firm on our audited financial statements for the year ended December 31, 2021 included a
“going concern” explanatory paragraph indicating that our recurring losses from operations, negative working capital, recurring negative cash flows from
operations and substantial cumulative net losses raise substantial doubt about our ability to continue as a going concern.

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

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

•

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

•

the number of product candidates we pursue;

our ability to develop and advance our current product candidates and programs into, and successfully complete, clinical studies;

the time and costs involved in obtaining regulatory approvals;

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

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

the effect of competing technological and market developments;

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

general market conditions for offerings from biopharmaceutical companies;

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

our obligations under our debt arrangements;

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

our ability to retain the continued service of our key professionals and to identify, hire and retain additional qualified personnel;

the effect of the COVID-19 pandemic; and

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

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

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

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

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

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

decline or require that we wind down our operations altogether.

Our portfolio of marketable securities is subject to market, interest and credit risk that may reduce its value.

We maintain a portfolio of marketable securities. Changes in the value of our portfolio of marketable securities could adversely affect our earnings.

In particular, the value of our investments may decline due to increases in interest rates, downgrades of the bonds and other securities included in our
portfolio, instability in the global financial markets that reduces the liquidity of securities included in our portfolio, declines in the value of collateral
underlying the securities included in our portfolio and other factors. In addition, the COVID-19 pandemic has and may continue to adversely affect the
financial markets in some or all countries worldwide. Each of these events may cause us to record charges to reduce the carrying value of our investment
portfolio or sell investments for less than our acquisition cost. Although we attempt to mitigate these risks through diversification of our investments and
continuous monitoring of our portfolio’s overall risk profile, the value of our investments may nevertheless decline.

Risks Related to Our Business and Industry

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

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

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

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

variety of functions, including:

•

developing our technology platform;

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

identifying, developing, manufacturing and commercializing product candidates;

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

participating in regulatory approval processes;

formulating and manufacturing products; and

conducting sales and marketing activities.

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

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

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

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

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

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

•

obtaining regulatory approval to commence a trial;

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

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

•

recruiting suitable patients to participate in a trial;

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

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

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

adding new clinical trial sites; or

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

Patient enrollment, a significant factor in the timing of clinical trials, is affected by many factors, including the size and nature of the patient
population, the proximity of patients to clinical sites, the eligibility criteria for the trial, the design of the clinical trial, competing clinical trials and
clinicians’ and patients’ perceptions as to the potential advantages of the product candidate being studied in relation to other available therapies, including
any new drugs that may be approved for the indications we are investigating, as well as the COVID-19 pandemic. Furthermore, we intend to rely on CROs
and clinical trial sites to ensure the proper and timely conduct of our clinical trials and we intend to have agreements governing their committed activities,
but we will have limited influence over their actual performance.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

•

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Disruptions at the FDA, the MHRA, the EMA and comparable foreign authorities may also slow the time necessary for new drugs to be reviewed

and/or approved by necessary government agencies, which would adversely affect our business. For example, over the last several years, the U.S.
government has shut down several times and certain regulatory agencies, such as the FDA, have had to furlough critical FDA and other government
employees and stop critical activities. If a prolonged government shutdown occurs, it could significantly impact the ability of the FDA to timely review and
process our regulatory submissions, which could have a material adverse effect on our business.

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

ADCs and our antibody-drug-nanoparticle albumin-bound (“ADNAB”) platform are emerging technologies and, consequently, it is conceivable that

such technologies may ultimately fail to identify commercially viable products to treat human patients with cancer or other diseases. Due to the unproven
nature of ADCs and ADNABs, significant further research and development activities will be required. We may incur substantial costs in connection with
such research and development activities and there is no guarantee that these activities will lead to the identification of commercially viable products.

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

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

significant strain on our limited human and financial resources. As a result, we may not be able to provide sufficient resources to any single product
candidate to permit the successful development and commercialization of such product candidate, causing material harm to our business. Our resource
allocation decisions may cause us to fail to capitalize on viable commercial products or profitable market opportunities. Our spending on current and future
research and development programs and product candidates for specific indications may not yield any commercially viable products.

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

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

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

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

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

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

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

•

regulatory authorities may withdraw approvals of such products;

regulatory authorities may require additional warnings on the label;

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

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

our reputation may suffer.

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

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

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

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

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

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

or terminated and we may not be able to obtain regulatory approval for or successfully commercialize our product candidates. As a result, our results of
operations and the commercial prospects for our product candidates would be harmed, our costs could increase and our ability to generate revenues could
be delayed.

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

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

We currently manufacture some of our preclinical and clinical materials in-house. In addition, we may enter into collaboration and license
agreements with certain collaborators, pursuant to which we may, among other things, agree to carry out manufacturing of our collaborators’ material and
product candidates. However, we only recently began manufacturing such materials and do not have significant prior experience manufacturing preclinical
or clinical materials or product candidates. Before we can begin commercial manufacture of our or any potential collaborators’ materials or product
candidates, regulatory authorities must approve marketing applications that identify manufacturing facilities operated by us or our contract manufacturers
that have passed regulatory inspection and manufacturing processes that are acceptable to the regulatory authorities. In addition, our pharmaceutical
manufacturing facilities are continuously subject to scheduled and unannounced inspection by the FDA and international regulatory authorities, before and
after product approval, to monitor and ensure compliance with cGMP and other regulations. Additionally, we may use contract manufacturers for the
manufacture of our product candidates from time to time based on capacity needs. Although we are not involved in the day-to-day operations of our
contract manufacturers, we are ultimately responsible for ensuring that our products are manufactured in accordance with cGMP regulations.

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

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

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

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

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

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

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

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

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

would be delayed or there would be a shortage in supply, which would impair our ability to generate revenues from the sale of our product candidates.

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

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

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

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

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

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

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

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

We face potential business disruptions and related risks resulting from the COVID-19 pandemic, which could have a material adverse effect on our
business, financial condition and results of operations.

The COVID-19 pandemic continues to impact the global economy. Financial markets have experienced, and continue to experience, extreme
fluctuations that may cause a contraction in available liquidity globally as important segments of the credit markets react to the development. The COVID-
19 pandemic continues to rapidly evolve, and the extent to which COVID-19 may impact our business, clinical trials and sales of ZTlido will depend on
future developments, which are highly uncertain and cannot be predicted with confidence, such as the continued spread of the disease and variants thereof,
including any future variants, the duration of the outbreak, vaccination rates, travel restrictions and social distancing in the United States and other
countries, business closures or business disruptions and the effectiveness of actions taken in the United States and other countries to contain and treat the
disease.

We are monitoring the continuing impact of the COVID-19 pandemic, and we may continue to experience disruptions that could severely impact the

development of our product candidates, including:

•

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

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

decreases in patients seeking treatment for chronic pain;

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

•

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

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

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

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

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

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

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

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

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

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

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

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

Management is actively monitoring the global situation on our financial condition, liquidity, operations, suppliers, industry and workforce. Given
the continued evolution of the COVID-19 outbreak and the global responses to curb its spread, we are not able to estimate the effects of the COVID-19
outbreak on our results of operations, financial condition or liquidity for fiscal year 2022.

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

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

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

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

and record keeping related to collaborators’ products or product candidates. Noncompliance with any applicable regulatory requirements can result in
government refusal to approve (i) facilities for testing or manufacturing product

candidates or (ii) potential products for commercialization. The FDA and other regulatory agencies can delay, limit or deny approval for many reasons,
including:

•

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

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

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

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

In addition, if new legislation or regulations are enacted or existing legislation or regulations are amended or are interpreted or enforced differently,
we may be required to obtain additional approvals or operate according to different manufacturing or operating standards. This may require a change in our
development and manufacturing techniques or additional capital investments in our facilities. Any related costs may be significant. If we fail to comply
with applicable regulatory requirements in the future, then we may be subject to warning letters and/or civil or criminal penalties and fines, suspension or
withdrawal of regulatory approvals, product recalls, seizure of products, restrictions on the import and export of products, debarment, exclusion,
disgorgement of profits, operating restrictions and criminal prosecution and the loss of contracts and resulting revenue losses. Inspections by regulatory
authorities that identify any deficiencies could result in remedial actions, production stoppages or facility closure, which would disrupt the manufacturing
process and supply of product to our collaborators. In addition, such failure to comply could expose us to contractual and product liability claims, including
claims by collaborators for reimbursement for lost or damaged active pharmaceutical ingredients or recall or other corrective actions, the costs of which
could be significant.

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

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

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

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

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

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

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

to be adversely affected.

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

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

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

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

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

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

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

•

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

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

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

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

obtain adequate supply of Scilex Holding’s products;

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

comply with applicable legal and regulatory requirements.

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

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

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

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

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

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

Our FDA approval for ZTlido and any other regulatory approvals that we may receive for our product candidates may be subject to limitations on

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

•

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

fines, warning letters or holds on clinical trials;

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

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

injunctions or the imposition of civil or criminal penalties.

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

product candidates. If we are slow or unable to adapt to changes in existing requirements or the adoption of new requirements or policies, or if we are not
able to maintain regulatory compliance, we may lose any marketing approval that we may have obtained, which would adversely affect our business,
prospects and ability to achieve or sustain profitability.

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

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

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

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

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

The process of proposing, negotiating and implementing a license or acquisition of a product candidate or approved product is lengthy and complex.

Other companies, including some with substantially greater financial, marketing and sales resources, may

compete with us for the license or acquisition of product candidates and approved products. We have limited resources to identify and execute the
acquisition or in-licensing of third-party products, businesses and technologies and integrate them into our current infrastructure. Moreover, we may devote
resources to potential acquisitions or in-licensing opportunities that are never completed, or we may fail to realize the anticipated benefits of such efforts.
We may not be able to acquire the rights to additional product candidates on terms that we find acceptable, or at all.

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

•

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

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

higher than expected acquisition and integration costs;

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

increased amortization expenses;

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

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

inability to motivate key employees of any acquired businesses; and

assumption of known and unknown liabilities.

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

testing and approval by the FDA and applicable foreign regulatory authorities. All product candidates are prone to risks of failure typical of pharmaceutical
product development, including the possibility that a product candidate will not be shown to be sufficiently safe and effective for approval by regulatory
authorities.

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

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

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

•

the efficacy and safety as demonstrated in clinical trials;

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

the clinical indications for which the product candidate is approved;

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

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

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

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

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

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

the prevalence and severity of adverse side effects; and

the effectiveness of our sales and marketing efforts.

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

current standard of care or otherwise does not provide patient benefit, that product candidate, if approved for commercial sale by the FDA or other
regulatory authorities, likely will not achieve market acceptance. Our ability to effectively

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

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

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

•

developing product candidates and technologies generally;

undertaking preclinical testing and clinical trials;

obtaining FDA and other regulatory approvals of product candidates;

formulating and manufacturing product candidates; and

launching, marketing and selling product candidates.

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

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

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

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

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

•

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

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

attract and retain key personnel;

•

develop relationships with physicians prescribing these products; and

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

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

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

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

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

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

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

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

In some foreign countries, particularly in the European Union, the pricing of prescription pharmaceuticals is subject to governmental control. In

these countries, pricing negotiations with governmental authorities can take considerable time after the receipt of marketing approval for a product
candidate. To obtain reimbursement or pricing approval in some countries, we may be required to conduct additional clinical trials that compare the cost-
effectiveness of our product candidates to other available therapies. If reimbursement of our product candidates is unavailable or limited in scope or amount
in a particular country, or if pricing is set at unsatisfactory levels, we may be unable to achieve or sustain profitability of our products in such country.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

•

funding research, preclinical development, clinical trials and manufacturing;

seeking and obtaining regulatory approvals;

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

successfully commercializing any future product candidates.

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

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

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

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

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

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

From time to time we may engage in efforts to enter into licensing, distribution and/or collaboration agreements with one or more pharmaceutical or
biotechnology companies to assist us with development and/or commercialization of our other product candidates. If we are successful in entering into such
agreements, we may not be able to negotiate agreements with economic terms similar to those negotiated by other companies. We may not, for example,
obtain significant upfront payments, substantial royalty rates or milestones. If we fail to enter into any such agreements in a timely manner or at all, our
efforts to develop and/or commercialize our product candidates may be undermined. In addition, if we do not raise funds through any such agreements, we
will need to rely on other financing mechanisms, such as sales of debt or equity securities, to fund our operations. Such financing mechanisms, if available,
may not be sufficient or timely enough to advance our programs forward in a meaningful way in the short-term.

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

•

competition in seeking appropriate collaborators;

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

inability to negotiate collaborations on acceptable terms;

inability to negotiate collaborations on a timely basis;

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

•

a potential collaborator’s resources and expertise; and

restrictions due to an existing collaboration agreement.

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

we are seeking to collaborate, reduce or delay its development program or those for other of our other development programs, delay its potential
commercialization or reduce the scope of any sales or marketing activities, or increase our expenditures and undertake development or commercialization
activities at our own expense. If we elect to increase our expenditures to fund development or commercialization activities on our own, we may need to
obtain additional capital, which may not be available to us on acceptable terms or at all. If we do not have sufficient funds, we may not be able to develop
or commercialize our product candidates.

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

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

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

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

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

•

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

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

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

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

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

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

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

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

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

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

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

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

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

increased privacy and security obligations on entities handling personal data of consumers or households. The CCPA requires covered companies to
provide new disclosure to consumers about such companies’ data collection, use and sharing practices, provide such consumers new ways to opt-out of
certain sales or transfers of personal information, and provide consumers with additional causes of action. The CCPA went into effect on January 1, 2020,
and beginning July 1, 2020, the California Attorney General may bring enforcement actions for violations. The CCPA, among other things, requires
covered companies to provide disclosures to California consumers concerning the collection and sale of personal information, and will give such
consumers the right to opt-out of certain sales of personal information. The CCPA may increase our company`s compliance costs and potential liability, and
we cannot yet predict the impact of the CCPA on our business. In addition, a new California privacy law, the California Privacy Rights Act (the “CPRA”)
was passed by California voters on November 3, 2020. The CPRA will create additional obligations with respect to processing and storing personal
information that are scheduled to take effect on January 1, 2023 (with certain provisions having retroactive effect to January 1, 2022). Further, a new
Virginia privacy law, Virginia Consumer Data Protection Act (“VCDPA”) was signed into law on March 2, 2021 and is also scheduled to take effect on
January 1, 2023, and the Colorado Privacy Act (“CPA”) will take effect on July 1, 2023. The VCDPA and CPA will impose many similar obligations
regarding the processing and storing of personal information as the CCPA and the CPRA.

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

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

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

We can provide no assurance that future legislation will not prevent us from generating or maintaining personal data or that patients will consent to

the use of their personal information, either of which may prevent us from undertaking or publishing essential

research. These burdens or risks may prove too great for us to reasonably bear and may adversely affect our ability to achieve profitability or maintain
profitably in the future.

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

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

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

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

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

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

We may be exposed to liability claims associated with the use of hazardous materials and chemicals. If we fail to comply with environmental, health
and safety laws and regulations, we could become subject to fines or penalties or incur costs that could harm our business.

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

In addition, we may incur substantial costs in order to comply with current or future environmental, health and safety laws and regulations. These
current or future laws and regulations may impair our research, development or production efforts. Our failure to comply with these laws and regulations
also may result in substantial fines, penalties or other sanctions.

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

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

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

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

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

number of qualified personnel among biopharmaceutical, biotechnology, pharmaceutical and other businesses. Many of the other pharmaceutical
companies that we compete against for qualified personnel have greater financial and other resources, different risk profiles and a longer history in the
industry than we do. They also may provide more diverse opportunities and better chances for career advancement. Some of these characteristics may be
more appealing to high quality candidates than what we have to offer. In addition, we may experience employee turnover as a result of the ongoing “great
resignation” occurring throughout the U.S. economy, which has impacted job market dynamics. New hires require training and take time before they
achieve full productivity. New employees may not become as productive as we expect, and we may be unable to hire or retain sufficient numbers of
qualified individuals. If we are unable to continue to attract and retain high quality personnel, the rate and success at which we can develop and
commercialize product candidates will be limited.

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

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

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

We are exposed to the risk of employee fraud or other misconduct. Misconduct by employees could include intentional failures to comply with FDA
regulations, provide accurate information to the FDA, comply with manufacturing standards we have established, comply with federal and state health-care
fraud and abuse laws and regulations, comply with laws and regulations (including, but not limited to the Foreign Corrupt Practices Act of 1977, as
amended, 15 U.S.C. §§ 78dd-1 (“FCPA”)) and internal policies restricting payments to government agencies and representatives, report financial
information or data accurately or disclose unauthorized activities to us. In particular, sales, marketing and business arrangements in the healthcare industry
are subject to extensive laws and regulations intended to prevent fraud, kickbacks, self-dealing and other abusive practices. These laws and regulations may
restrict or prohibit a wide range of pricing, discounting, marketing and promotion, sales commission, customer incentive programs and other business
arrangements. Employee misconduct could also involve the improper use of information obtained in the course of clinical trials, which could result in
regulatory sanctions and serious harm to our reputation. We have adopted a Code of Business Conduct and Ethics, but it is not always possible to identify
and deter employee misconduct, and the precautions we take to detect and prevent this activity may not be effective in controlling unknown or unmanaged
risks or losses or in protecting us from governmental

investigations or other actions or lawsuits stemming from a failure to be in compliance with such laws or regulations. If any such actions are instituted
against us, and we are not successful in defending ourselves or asserting our rights, those actions could have a significant impact on our business and
results of operations, including the imposition of significant fines or other sanctions.

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

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

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

•

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

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

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

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

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

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

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

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

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

commercialization of any products, including ZTlido, which is marketed and sold through our subsidiary, Scilex Holding. For example, we may be sued if
any product we develop allegedly causes injury or is found to be otherwise unsuitable during product testing, manufacturing, marketing or sale. Any such
product liability claims may include allegations of defects in manufacturing, defects in design, a failure to warn of dangers inherent in the product,
negligence, strict liability, and a breach of warranties. Claims could also be asserted under state consumer protection acts. If we cannot successfully defend
ourselves against product liability claims, we may incur substantial liabilities or be required to limit commercialization of our product candidates, if
approved. Even successful defense would require significant financial and management resources. Regardless of the merits or eventual outcome, liability
claims may result in:

•

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

injury to our reputation;

withdrawal of clinical trial participants;

initiation of investigations by regulators;

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

costs to defend the related litigation;

•

a diversion of management’s time and our resources;

substantial monetary awards to trial participants or patients;

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

loss of revenues from product sales; and

the inability to commercialize our product candidates.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

An Emergency Use Authorization (“EUA”) would allow us to market and sell our COVID-19 product candidates, including COVISTIX, without the

need to pursue the lengthy and expensive drug or device approval process. The FDA may issue an EUA during a public health emergency if it determines
that the potential benefits of a product outweigh the potential risks and if other regulatory criteria are met. If an EUA is granted for any of our COVID-19
product candidates, we will rely on the FDA policies and guidance in connection with the marketing and such product candidates. If these policies and
guidance change unexpectedly and/or materially or if we misinterpret them, potential sales of our COVID-19 product candidates could be adversely
impacted. In addition, the FDA may revoke an EUA where it is determined that the underlying health emergency no longer exists or warrants such
authorization. If granted, we cannot predict how long an EUA for our COVID-19 product candidates would remain in place. The termination of an EUA, if
granted, could adversely impact our business, financial condition and results of operations.

We may also seek additional EUAs from the FDA for our other product candidates for the detection and/or treatment of COVID-19 and the SARS-
CoV-2 virus. If granted, the additional EUAs would allow us to market and sell additional product candidates without the need to pursue the lengthy and
expensive drug approval process. There is no guarantee that we will be able to obtain any additional EUAs. Failure to obtain additional EUAs or the
termination of such EUAs, if obtained, could adversely impact our business, financial condition and results of operations.

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

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

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

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

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

In addition, government-imposed travel restrictions, quarantines, shelter-in-place, shutdowns and similar government orders in response to the

continuing COVID-19 pandemic have resulted, and may continue to result, in direct operational and administrative disruptions to our facilities. Our
operations would be disrupted if any of our employees or employees of our business partners were suspected of having contracted COVID-19, which could
require quarantine of some or all such employees or closure of our facilities for disinfection. If the operations in our principal executive offices or other
facilities are disrupted by a surge of COVID-19 that results in new orders by the health officer of San Diego County, the Governor of California or the State
Public Health and Director of the California Department of Public Health, we may not be able to operate for the duration of such order, which could
negatively impact our business, operating results and financial condition.

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

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

vulnerable to damage from computer viruses, unauthorized access, cybersecurity attacks or hacking, natural disasters, terrorism, war and
telecommunication and electrical failures. In addition, as a result of the COVID-19 pandemic, we may face increased cybersecurity risks due to our
reliance, and the reliance of our CROs, contractors and consultants reliance, on internet technology and the number of our employees, and employees of
our CROs, contractors and consultants, who are working remotely, which may create additional opportunities for cybercriminals to exploit vulnerabilities.
While we have not experienced any such system failure, accident or security breach to date, if such an event were to occur and cause interruptions in our
operations, it could result in a material disruption of our drug development programs. For example, the loss of clinical trial data from completed or ongoing
or planned clinical trials could result in delays in our regulatory approval efforts and significantly increase our costs to recover or reproduce the data. To the
extent that any disruption or security breach was to result in a loss of or damage to our data or applications, or inappropriate disclosure of confidential or
proprietary information, we could incur material legal claims and liability, damage to our reputation, suffer loss or harm to our intellectual property rights
and the further research, development and commercial efforts of our products and product candidates could be delayed. If we are held liable for a claim
against which we are not insured or for damages exceeding the limits of our insurance coverage, whether arising out of cybersecurity matters, or from some
other matter, that claim could have a material adverse effect on our results of operations.

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

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

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

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

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

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

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

well as customary additional affirmative covenants, such as furnishing financial statements to the holders of the Scilex Notes, minimum cash requirements
and net sales reports, and negative covenants, including limitations on the following: the incurrence of debt, the payment of dividends by Scilex Pharma,
the repurchase of shares and, under certain conditions, making certain other restricted payments, the prepayment, redemption or repurchase of subordinated
debt, a merger, amalgamation or consolidation involving Scilex Pharma, engaging in certain transactions with affiliates; and the making of investments
other than those permitted by the Scilex Indenture. In addition, if actual cumulative net sales of ZTlido for the period from October 1, 2022 through
September 30, 2023 do not equal or exceed 80% of a predetermined target sales threshold for such period, the aggregate principal amount shall also be
increased on November 15, 2023 by an amount equal to an amount to be determined by reference to the amount of such deficiency. There can be no
assurance that net sales of ZTlido for the period from October 1, 2022 through September 30, 2023 will meet the predetermined target sales threshold, and
if the principal amount of the Scilex Notes is increased, we may need to obtain additional financing, and cannot be sure that any additional funding, if
needed, will be available on terms favorable to us, or at all.

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

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

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

Our ability to utilize our net operating loss and tax credit carryforwards may be limited.

Section 382 of the Internal Revenue Code of 1986, as amended, and the rules and regulations thereunder (“Section 382”) limit a corporation’s ability

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

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

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

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

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

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

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

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

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

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

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

•

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

unexpected increases in taxes or tariffs;

trade protection measures or import or export licensing requirements;

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

fluctuations in foreign currency exchange rates;

difficulties in staffing and managing international operations;

less favorable intellectual property or other applicable laws;

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

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

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

divergent legal systems and regulatory frameworks; and

political and economic instability or corruption.

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

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

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

Interbank Offered Rate (“LIBOR”) and the sale of LIBOR-indexed securities. In July 2017, the United Kingdom’s Financial Conduct Authority, which
regulates LIBOR, announced its intention to stop persuading or compelling the group of major banks that sustain LIBOR to submit rate quotations after
2021. Effective December 31, 2021, LIBOR will no longer be used to price new loans and one-week and two-month LIBOR will no longer be published.
However, overnight, 1-month, 3-month, 6-month, and 12-month maturities will continue to be published through June 2023.

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

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

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

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

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

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

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

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

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

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

merit, may also result in settlements, injunctions or damages that could have a material adverse effect on our business, financial condition and results of
operations.

Investors’ expectations of our performance relating to environmental, social and governance factors may impose additional costs and expose us to new
risks.

There is an increasing focus from certain investors, employees, regulators and other stakeholders concerning corporate responsibility, specifically

related to environmental, social and governance (“ESG”) factors. Some investors and investor advocacy groups may use these factors to guide investment
strategies and, in some cases, investors may choose not to invest in our company if they believe our policies relating to corporate responsibility are
inadequate. Third-party providers of corporate responsibility ratings and reports on companies have increased to meet growing investor demand for
measurement of corporate responsibility performance, and a variety of organizations currently measure the performance of companies on such ESG topics,
and the results of these assessments are widely publicized. Investors, particularly institutional investors, use these ratings to benchmark companies against
their peers and if we are perceived as lagging with respect to ESG initiatives, certain investors may engage with us to improve ESG disclosures or
performance and may also make voting decisions, or take other actions, to hold us and our board of directors accountable. In addition, the criteria by which
our corporate responsibility practices are assessed may change, which could result in greater expectations of us and cause us to undertake costly initiatives
to satisfy such new criteria. If we elect not to or are unable to satisfy such new criteria, investors may conclude that our policies with respect to corporate
responsibility are inadequate. We may face reputational damage in the event that our corporate responsibility procedures or standards do not meet the
standards set by various constituencies.

We may face reputational damage in the event our corporate responsibility initiatives or objectives do not meet the standards set by our investors,

stockholders, lawmakers, listing exchanges or other constituencies, or if we are unable to achieve an acceptable ESG or sustainability rating from third-
party rating services. A low ESG or sustainability rating by a third-party rating service could also result in the exclusion of our common stock from
consideration by certain investors who may elect to invest with our competition instead. Ongoing focus on corporate responsibility matters by investors and
other parties as described above may impose additional costs or expose us to new risks. Any failure or perceived failure by us in this regard could have a
material adverse effect on our reputation and on our business, share price, financial condition, or results of operations, including the sustainability of our
business over time.

We are subject to recently enacted state laws in California that require gender and diversity quotas for boards of directors of public companies
headquartered in California.

In September 2018, California enacted Senator Bill 826 (“SB 826”), which generally requires public companies with principal executive offices in
California to have at least two female directors on its board of directors if the company has at least five directors, and at least three female directors on its
board of directors if the company has at least six directors.

Additionally, on September 30, 2020, California enacted Assembly Bill 979 (“AB 979”), which generally requires public companies with principal

executive offices in California to include specified numbers of directors from “underrepresented communities”. A director from an “underrepresented
community” means a director who self-identifies as Black, African American, Hispanic, Latino, Asian, Pacific Islander, Native American, Native
Hawaiian, Alaska Native, gay, lesbian, bisexual or transgender. By December 31, 2021, each public company with principal executive offices in California
was required to have at least one director from an underrepresented community. By December 31, 2022, a public company with more than four but fewer
than nine directors will be required to have a minimum of two directors from underrepresented communities, and a public company with nine or more
directors will need to have a minimum of three directors from underrepresented communities.

We cannot assure that we can recruit, attract and/or retain qualified members of the board and meet gender and diversity quotas as required by SB
826 or AB 979, and our board of directors does not currently satisfy the quota required under SB 826. A failure to comply with either SB 826 or AB 979
could result in fines from the California Secretary of State, with a $100,000 fine for the first violation and a $300,000 fine for each subsequent violation of
either law, and our reputation may be adversely affected.

Risks Related to Acquisitions

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

businesses and technologies.

For example, in November 2016, we acquired a majority of the outstanding capital stock of Scilex Pharma, which was contributed to our majority-

owned subsidiary Scilex Holding in connection with the corporate reorganization of Scilex Holding and acquisition of Semnur by Scilex Holding in March
2019. These assets, together, constitute our Scilex segment. We also acquired Virttu Biologics Limited in 2017, SOFUSA assets, a revolutionary drug
delivery technology, in July 2018 and SmartPharm Therapeutics, Inc. in September 2020. In June 2021, we acquired ACEA Therapeutics, Inc. and in
February 2022, we acquired Virex Health, Inc., and are in the process of integrating these two companies and their technologies with ours.

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

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

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

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

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

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

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

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

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

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

These milestone obligations could impose substantial additional costs on our Scilex operating segment, divert resources from other aspects of its
business, and adversely affect the overall profitability of SEMDEXA, if approved. We may need to obtain additional financing to satisfy these milestone
payments, and cannot be sure that any additional funding, if needed, will be available on terms favorable to us, or at all.

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

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

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

•

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

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

diversion of financial and managerial resources from existing operations;

•

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

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

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

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

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

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

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

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

Risks Related to Our Intellectual Property

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

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

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

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

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

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

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

We may become involved in lawsuits to protect or enforce our patents or other intellectual property, which could be expensive, time consuming and
unsuccessful.

Competitors may infringe our patents, trademarks, copyrights or other intellectual property. To counter infringement or unauthorized use, we may be

required to file infringement claims, which can be expensive and time consuming and divert the time and attention of our management and scientific
personnel. Any claims we assert against perceived infringers could provoke these parties to assert counterclaims against us alleging that we infringe their
patents, in addition to counterclaims asserting that our patents are invalid or unenforceable, or both. In any patent infringement proceeding, there is a risk
that a court will decide that a patent of ours is invalid or unenforceable, in whole or in part, and that we do not have the right to stop the other party from
using the invention at issue. There is also a risk that, even if the validity of such patents is upheld, the court will construe the patent’s claims narrowly or
decide that we do not have the right to stop the other party from using the invention at issue on the grounds that our patent claims do not cover the
invention. An adverse outcome in a litigation or proceeding involving our patents could limit our ability to assert our patents against those parties or other
competitors, and may curtail or preclude our ability to exclude third parties from making and selling similar or competitive products. Any of these
occurrences could adversely affect our competitive business position, business prospects and financial condition. Similarly, if we assert trademark
infringement claims, a court may determine that the marks we have asserted are invalid or unenforceable, or that the party against whom we have asserted
trademark infringement has superior rights to the marks in question. In this case, we could ultimately be forced to cease use of such trademarks.

Even if we establish infringement, the court may decide not to grant an injunction against further infringing activity and instead award only
monetary damages, which may or may not be an adequate remedy. Furthermore, because of the substantial amount of discovery required in connection with
intellectual property litigation, there is a risk that some of our confidential information could be compromised by disclosure during litigation. There could
also be public announcements of the results of hearings, motions or other interim proceedings or developments. If securities analysts or investors perceive
these results to be negative, it could have a material adverse effect on the price of shares of our common stock. Moreover, there can be no assurance that we
will have sufficient financial or other resources to file and pursue such infringement claims, which typically last for years before they are concluded. Even
if we ultimately prevail in such claims, the monetary cost of such litigation and the diversion of the attention of our management and scientific personnel
could outweigh any benefit we receive as a result of the proceedings.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

•

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

redesign our products or processes to avoid infringement;

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

•

pay damages; and

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

and results of operations.

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

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

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

•

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

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

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

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

Our pending patent applications may not lead to issued patents;

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

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

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

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

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

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

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

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

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

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

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

Risks Related to Ownership of Our Common Stock

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

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

time to time experienced significant price and volume fluctuations that are unrelated to the operating performance of particular companies. For example,
from January 4, 2021 to December 31, 2021, our closing stock price ranged from $4.65 to $16.51

per share. The market price of our common stock may fluctuate significantly in response to numerous factors, some of which are beyond our control, such
as:

•

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

our failure to commercialize our product candidates, if approved;

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

adverse regulatory decisions;

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

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

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

our dependence on third parties, including CROs;

announcements of the introduction of new products by our competitors;

market conditions in the pharmaceutical and biotechnology sectors;

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

future issuances of common stock or other securities;

the addition or departure of key personnel;

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

actual or anticipated variations in quarterly operating results;

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

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

conditions or trends in the biotechnology and biopharmaceutical industries;

introduction of new products offered by us or our competitors;

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

issuances of debt or equity securities;

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

trading volume of our common stock;

ineffectiveness of our internal controls;

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

failure to effectively integrate the acquired companies’ operations;

general political and economic conditions;

effects of natural or man-made catastrophic events;

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

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

Further, the equity markets in general have recently experienced extreme price and volume fluctuations. Continued market fluctuations could result

in extreme volatility in the price of our common stock, which could cause a decline in the value of our

common stock. Price volatility of our common stock might worsen if the trading volume of our common stock is low. The realization of any of the above
risks or any of a broad range of other risks, including those described in these “Risk Factors,” could have a dramatic and material adverse impact on the
market price of our common stock.

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

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

Our strategic investments may result in losses.

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

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

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

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

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

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

Our quarterly operating results may fluctuate significantly.

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

including:

•

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

the addition or termination of clinical trials;

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

regulatory developments affecting our product candidates; and

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

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

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

We may issue additional equity securities to fund future expansion and pursuant to equity incentive or employee benefit plans. We may also issue

additional equity for other purposes. These securities may have the same rights as our common stock or,

alternatively, may have dividend, liquidation or other preferences to our common stock. The issuance of additional equity securities will dilute the holdings
of existing stockholders and may reduce the share price of our common stock.

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

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

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

As of December 31, 2021, 61.3 million shares of our common stock were reserved for issuance under our equity incentive plans, of which 22.5

million shares of our common stock were subject to options outstanding at such date at a weighted-average exercise price of $6.19 per share, 3.4 million
shares of our common stock were subject to outstanding restricted stock units, 3.2 million shares of our common stock were reserved for issuance pursuant
to our 2019 Stock Incentive Plan and 7.2 million shares of our common stock were reserved for issuance pursuant to our 2020 Employee Stock Purchase
Plan. In addition, 24,935,882 shares of our common stock are subject to the 10-year CEO performance award granted to Dr. Ji that is tied solely to
achieving market capitalization milestones and has an exercise price of $17.30 per share. To the extent outstanding options are exercised, our existing
stockholders may incur dilution.

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

and other service providers may further dilute our stockholders.

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

As of February 28, 2022, our directors and executive officers beneficially owned, in the aggregate, approximately 3.0% of our outstanding voting

securities. As a result, if some or all of them acted together, they would have the ability to exert significant influence over the election of our board of
directors and the outcome of issues requiring approval by our stockholders. This concentration of ownership may also have the effect of delaying or
preventing a change in control of our company that may be favored by other stockholders. This could prevent transactions in which stockholders might
otherwise recover a premium for their shares over current market prices.

Our certificate of incorporation, as amended, and bylaws provide for indemnification of officers and directors at our expense and limits their liability,
which may result in a major cost to us and hurt the interests of our stockholders because corporate resources may be expended for the benefit of our
officers and/or directors.

Our certificate of incorporation, as amended, bylaws and applicable Delaware law provide for the indemnification of our directors, officers,
employees, and agents, under certain circumstances, against attorney’s fees and other expenses incurred by them in any litigation to which they become a
party arising from their association with or activities on our behalf. We will also bear the expenses of such litigation for any of our directors, officers,
employees, or agents, upon such person’s promise to repay us, therefore if it is ultimately determined that any such person shall not have been entitled to
indemnification. This indemnification policy could result in substantial expenditures by us, which we will be unable to recover.

Our corporate documents and Delaware law contain provisions that could discourage, delay or prevent a change in control of our company, prevent
attempts to replace or remove current management and reduce the market price of our common stock.

Provisions in our certificate of incorporation, as amended, and bylaws may discourage, delay or prevent a merger or acquisition involving us that

our stockholders may consider favorable. For example, our certificate of incorporation, as amended, authorizes our board of directors to issue up to
100,000,000 shares of “blank check” preferred stock. As a result, without further stockholder approval, the board of directors has the authority to attach
special rights, including voting and dividend rights, to this preferred stock. With these rights, preferred stockholders could make it more difficult for a third
party to acquire us.

We are also subject to the anti-takeover provisions of the General Corporation Law of the State of Delaware. Under these provisions, if anyone
becomes an “interested stockholder,” we may not enter into a “business combination” with that person for three years without special approval, which
could discourage a third party from making a takeover offer and could delay or prevent a change in control of us. An “interested stockholder” means,
generally, someone owning 15% or more of our outstanding voting stock

or an affiliate of ours that owned 15% or more of our outstanding voting stock within the past three years, subject to certain exceptions as described in the
General Corporation Law of the State of Delaware.

Our Amended and Restated Bylaws provide that the Court of Chancery in the State of Delaware is the sole and exclusive forum for substantially all
disputes between us and our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our
directors, officers or employees.

Our Amended and Restated Bylaws (our “Bylaws”), provide that, unless our Board of Directors consents to an alternative forum, the Court of

Chancery in the State of Delaware will be the sole and exclusive forum for: (i) any derivative action or proceeding brought by or on our behalf; (ii) any
direct action asserting a claim against us or any of our directors or officers pursuant to any of the provisions of the General Corporation Law of the State of
Delaware, our Restated Certificate of Incorporation or our Bylaws; (iii) any action asserting a claim of breach of fiduciary duties owed by any of our
directors, officers or other employees to our stockholders; or (iv) any action asserting a violation of Delaware decisional law relating to our internal affairs.
This provision does not apply to (a) actions in which the Court of Chancery in the State of Delaware concludes that an indispensable party is not subject to
the jurisdiction of Delaware courts, or (b) actions in which a federal court has assumed exclusive jurisdiction to a proceeding. This choice of forum
provision is not intended to apply to any actions brought under the Securities Act of 1933, as amended, or the Securities Act, or the Securities Exchange
Act of 1934, as amended, or the Exchange Act. Section 27 of the Exchange Act creates exclusive federal jurisdiction over all suits brought to enforce any
duty or liability created by the Exchange Act or the rules and regulations thereunder. As a result, the exclusive forum provision will not apply to suits
brought to enforce any duty or liability created by the Exchange Act or any other claim for which the federal courts have exclusive jurisdiction. However,
our Bylaws do not relieve us of our duties to comply with federal securities laws and the rules and regulations thereunder, and our stockholders will not be
deemed to have waived our compliance with these laws, rules and regulations. Our Bylaws also provide that any person or entity purchasing or otherwise
acquiring any interest in shares of our capital stock will be deemed to have notice of and consented to this choice of forum provision.

This choice of forum provision in our Bylaws may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes

with us or our directors, officers or other employees, which may discourage such lawsuits against us and our directors, officers and other employees. In
addition, stockholders who do bring a claim in the Court of Chancery in the State of Delaware could face additional litigation costs in pursuing any such
claim, particularly if they do not reside in or near Delaware. Furthermore, the enforceability of similar choice of forum provisions in other companies’
governing documents has been challenged in legal proceedings, and it is possible that a court could find these types of provisions to be inapplicable or
unenforceable. If a court were to find the choice of forum provision in our Bylaws to be inapplicable or unenforceable in an action, we may incur additional
costs associated with resolving such action in other jurisdictions, which could adversely affect our business and financial condition.

Compliance with changing regulations concerning corporate governance and public disclosure may result in additional expenses.

There have been changing laws, regulations and standards relating to corporate governance and public disclosure, including the Dodd-Frank Wall
Street Reform and Consumer Protection Act (the “Dodd-Frank Act”), the Sarbanes-Oxley Act of 2002 (“Sarbanes-Oxley”), new regulations promulgated
by the U.S. Securities and Exchange Commission (the “SEC”) and rules promulgated by the national securities exchanges. The Dodd-Frank Act, enacted in
July 2010, expanded federal regulation of corporate governance matters and imposes requirements on public companies to, among other things, provides
stockholders with a periodic advisory vote on executive compensation and also adds compensation committee reforms and enhanced pay-for-performance
disclosures. While some provisions of the Dodd-Frank Act were effective upon enactment, others have been and will be implemented upon the SEC’s
adoption of related rules and regulations. The scope and timing of the adoption of such rules and regulations is uncertain and, accordingly, the cost of
compliance with the Dodd-Frank Act is also uncertain. Areas subject to potential change, amendment or repeal include the Dodd-Frank Act, including §
619 (12 U.S.C. § 1851) known as the Volcker Rule and various swaps and derivatives regulations, the authority of the Federal Reserve and the Financial
Stability Oversight Council, and renewed proposals to separate banks’ commercial and investment banking activities.

These new or changed laws, regulations and standards are, or will be, subject to varying interpretations in many cases due to their lack of specificity,

and, as a result, their application in practice may evolve over time as new guidance is provided by regulatory and governing bodies, which could result in
continuing uncertainty regarding compliance matters and higher costs necessitated by ongoing revisions to disclosure and governance practices. As a result,
our efforts to comply with evolving laws, regulations and standards are likely to continue to result in increased general and administrative expenses and a
diversion of management time and attention from revenue-generating activities to compliance activities. Members of our board of directors and our
principal executive officer and principal financial officer could face an increased risk of personal liability in connection with the performance of their
duties. As a result, we may have difficulty attracting and retaining qualified directors and executive officers, which could harm our business. If the actions
we take in our efforts to comply with new or changed laws, regulations and standards differ from the actions intended by regulatory or governing bodies,
we could be subject to liability under applicable laws or our reputation may be harmed.

We have identified a material weakness in our internal control over financial reporting, and our financial controls and procedures may not in the
future be sufficient to ensure timely and reliable reporting of financial information, which could, if not remediated, result in a material misstatement in
our financial statements and could adversely affect our future results of operations, our stock price, and our ability to raise capital.

A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting such that there is a reasonable
possibility that a material misstatement of our annual or interim consolidated financial statements will not be prevented or detected on a timely basis.

As previously disclosed on our Current Report on Form 8-K filed with the Securities and Exchange Commission on January 7, 2022, our former

Chief Financial Officer passed away unexpectedly on January 6, 2022. Due in large part to the unexpected passing of our former Chief Financial Officer,
our management has identified that we did not employ sufficient accounting resources with appropriate experience and technical expertise to effectively
execute controls over certain judgmental accounting areas. As a result, certain of our control activities in the areas of revenue, business combinations,
investments, debt, derivative liabilities and leases did not operate effectively and have been deemed deficient and the combination of the aforementioned
deficiencies represented a material weakness in our internal control over financial reporting as of December 31, 2021. The material weakness did not result
in a restatement of previously issued annual consolidated financial statements or condensed interim consolidated financial statements.

As a result of the material weakness, we are in the process of implementing remediation measures including, but not limited to, hiring a Chief
Financial Officer and other personnel with appropriate experience and technical expertise to effectively execute controls over judgmental accounting areas.
We believe that our remediation measures, if effectively implemented, will provide reasonable assurance regarding the reliability of financial reporting and
the preparation of our financial statements for external purposes in accordance with generally accepted accounting principles (“GAAP”). We cannot assure
you that the measures we have taken to date or any measures we may take in response to the material weakness in the future will be sufficient to remediate
such material weakness or to avoid potential future material weaknesses. Any failure to implement these improvements to our internal control over
financial reporting would result in a continued material weakness in our internal control and could impact our ability to produce reliable financial reports,
effectively manage the company or prevent fraud, and could potentially harm our business and our performance. Even if we develop effective controls,
these new controls may become inadequate because of changes in conditions or the degree of compliance with these policies or procedures may deteriorate.
If we experience future material weaknesses or deficiencies in internal controls and we are unable to correct them in a timely manner, our ability to record,
process, summarize and report financial information accurately and within the time periods specified in the rules and forms of the SEC, will be adversely
affected. Any such failure could negatively affect the market price and trading liquidity of our common stock, lead to delisting, cause investors to lose
confidence in our reported financial information, subject us to civil and criminal investigations and penalties, and generally materially and adversely impact
our business and financial condition.

results and the timing of events could differ materially from those anticipated in these forward-looking statements as a result of a number of factors,
including those set forth under the cautionary note regarding “Forward-Looking Statements” contained elsewhere in this Annual Report on Form 10-K.
Additionally, you should read the “Risk Factors” section of this Annual Report on Form 10-K for a discussion of important factors that could cause actual
results to differ materially from the results described in or implied by the forward-looking statements contained in the following discussion and analysis.

Overview

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

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

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

developing a broad-spectrum neutralizing antibody, STI-9167 (COVISHIELD), to be formulated both for IV and IN administration. STI-9167 (IV
formulation) and STI-9199 (IN formulation using STI-9167 drug substance) have not only been broadly effective in preclinical studies for prior VoCs but
are highly potent against the Omicron VoC. A healthy subject study for STI-9167/9199 is expected to begin in the first quarter of 2022 with Phase II studies
of COVISHIELD to follow.

We have also developed two promising potential rescue treatments with Abivertinib (STI-5656), an oral next generation dual epidermal growth
factor receptor (“EGFR”) (including mutant forms)/BTK inhibitor, or epidermal growth factor receptor/BTK inhibitor to treat hospitalized COVID-19
patients and COVI-MSC™ (samtonadstrocel or STI-8282), human allogeneic adipose-derived mesenchymal stromal cells for patients suffering from
COVID-19-induced acute respiratory distress (“ARD”). Both have been cleared by the FDA and Abivertinib has completed Phase II clinical studies in the
U.S. and Brazil of Abivertinib to treat COVID-19-induced acute respiratory distress syndrome (“ARDS”). While all patient groups improved with
treatment, the U.S. study identified an At-Risk population who were the best responders: those who required oxygen supplementation with non-invasive
ventilation or high flow oxygen at baseline. Although the Brazil study did not enroll a population as sick as those in the U.S. study, the results were
similarly supportive. In the U.S. study, the At-Risk patients were discharged on average two days sooner from the intensive care unit. In both studies, there
was nearly a 50% reduction of death and/or mechanical ventilation or extracorporeal membrane oxygenation by day 29. This data was used to power a
pivotal Phase III Abivertinib study which is expected to begin enrollment in the second quarter of 2022. Two separate Phase II COVI-MSC studies are
currently enrolling in Brazil and the U.S. in patients with COVID-19-induced ARDS. We are also working with Brazilian regulators (ANVISA) to conduct
a COVID-19 study with COVI-MSCs in pulmonary long-haul patients post-recovery from the acute infection.

In furtherance of our goal to enable early detection and treatment across the entire continuum of COVID-19 solutions, we are further developing a

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

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

Impact of COVID-19 on Our Business

We are closely monitoring the COVID-19 pandemic and its potential impact on our business. In an effort to protect the health and safety of our

employees, we took proactive action from the earliest signs of the outbreak, including implementing social distancing policies at our facilities, facilitating
remote working arrangements and imposing employee travel restrictions.

The extent to which COVID-19 may impact our business, clinical trials and sales of ZTlido will depend on future developments, which are highly
uncertain and cannot be predicted with confidence, such as the ultimate geographic spread of the disease, the duration of the outbreak, travel restrictions
and social distancing in the United States and other countries, business closures or business disruptions and the effectiveness of actions taken in the United
States and other countries to contain and treat the disease.

Recent Developments

On February 1, 2022, we completed the acquisition of Virex Health, Inc. (“Virex”) pursuant to that certain Agreement and Plan of Merger (the

Upon completion of the Initial Merger, the equityholders of Virex (the “Virex Equityholders”) became entitled to receive the following amounts (to

Results of Operations

The following discussion of our operating results explains material changes in our results of operations for the years ended December 31, 2021 and
2020. The discussion should be read in conjunction with the consolidated financial statements and related notes included elsewhere in this Annual Report
on Form 10-K. We operate in two operating and reportable segments, Sorrento Therapeutics and Scilex.

Comparison of the Years Ended December 31, 2021 and 2020

Revenues. Revenues were $52.9 million for the year ended December 31, 2021, as compared to $40.0 million for the year ended December 31,

2020.

Revenues in our Sorrento Therapeutics segment increased from $13.7 million to $24.4 million for the year ended December 31, 2021 compared to

the prior year and were primarily attributed to higher contract manufacturing service revenues.

Revenues in our Scilex segment increased from $26.3 million to $28.5 million for the year ended December 31, 2021 compared to the prior year due

to increased product sales of ZTlido.

Cost of revenues. Cost of revenues for the years ended December 31, 2021 and 2020 were $13.0 million and $9.9 million, respectively, and relate to

product sales, the sale of customized reagents and providing contract manufacturing services. The costs generally include employee-related expenses,
including salary and benefits, direct materials and overhead costs including rent, depreciation, utilities, facility maintenance and insurance.

Cost of revenues for our Sorrento Therapeutics segment increased by $1.6 million and was driven by the increase in revenues.

Cost of revenues for our Scilex segment increased by $1.5 million as compared to the prior year and was attributable to higher sales volumes of

ZTlido.

Research and development expenses. Research and development expenses for the years ended December 31, 2021 and 2020 were $206.9 million

and $111.3 million, respectively. Research and development expenses primarily include expenses associated with isolating and advancing human antibody
drug candidates derived from our libraries, as well as advancing our RTX, COVID-19, SP-102, Oncolytic Virus, antibody drug conjugate (“ADC”) and
oncology programs. Such expenses consist primarily of salaries and personnel-related expenses, stock-based compensation expense, clinical development
expenses, preclinical testing, lab supplies, consulting costs, depreciation and other expenses.

Research and development expenses for our Sorrento Therapeutics segment increased by $96.3 million as compared to the prior fiscal year and were

primarily driven by higher headcount and increased clinical development costs spent on advancing our various research and development programs.

Research and development expenses for our Scilex segment decreased by $0.8 million as compared to the prior fiscal year and were primarily driven

by lower clinical development costs.

We expect research and development expenses for both segments to increase as we: (i) advance various product candidates into clinical trials and

pursue other development, acquire, develop and manufacture clinical trial materials and increase other regulatory operating activities, (ii) incur incremental
expenses associated with our efforts to further advance a number of potential product candidates into preclinical development activities, (iii) continue to
identify and advance a number of fully human therapeutic antibody and ADC preclinical product candidates, (iv) incur higher salary, lab supply and
infrastructure costs in connection with supporting all of our programs, (v) invest in our joint ventures, collaborations or other third party agreements, and
(vi) expand our corporate infrastructure.

Acquired in-process research and development expenses. Acquired in-process research and development expenses for the year ended December 31,

2021was $24.2 million. These expenses related to the Aardvark Asset Purchase Agreement for $5.0 million and the entry into the Mount Sinai License
Agreement for $7.5 million during the period as further described in Note 7 of the accompanying notes to the consolidated financial statements in this
Annual Report on Form 10-K. These expenses also related to $10.2 million related to our investment in Deverra Therapeutics, Inc. during the period as
further described in Note 5 of the

accompanying notes to the consolidated financial statements in this Annual Report on Form 10-K. The remainder related to our investments in various
licensing arrangements entered into during the period. We recognized $43.0 million of acquired in-process research and development expenses for the year
ended December 31, 2020, which were primarily related to various licensing arrangements entered into during the year, as well as other investments in new
technologies and preclinical programs.

Selling, general and administrative expenses. General and administrative expenses for the years ended December 31, 2021 and 2020 were $196.9

million and $116.2 million, respectively and consisted primarily of salaries and personnel-related expenses, stock-based compensation expense,
professional fees, infrastructure expenses, legal and other general corporate expenses.

Selling, general and administrative expenses for our Sorrento Therapeutics segment increased by approximately $73.1 million as compared to the

prior fiscal year and were primarily attributed to higher headcount, professional fees and stock-based compensation expense as compared to the same
period of the prior year.

Selling, general and administrative expenses for our Scilex segment increased by approximately $7.6 million as compared to the prior fiscal year

and were primarily attributed to higher professional fees.

Loss on derivative liabilities. Loss on derivative liabilities for the year ended December 31, 2021 was $0.3 million compared to a loss of $6.6

million for the year ended December 31, 2020.

Loss on contingent consideration. During the year ended December 31, 2021, we recorded a loss on contingent consideration and acquisition
consideration payable of approximately $9.2 million resulting from the change in fair value of the Earn-Out Consideration associated with the acquisition
of ACEA Therapeutics, Inc. (“ACEA”). (See Note 3 and Note 7 of the accompanying notes to consolidated financial statements in this Annual Report on
Form 10-K). During the year ended December 31, 2020, we did not record any loss or gain on contingent consideration.

There was no gain or loss on derivative liabilities for our Sorrento Therapeutics segment during the year ended December 31, 2021. Gain on
derivative liabilities for our Sorrento Therapeutics segment for the year ended December 31, 2020 totaled $5.8 million and was primarily attributed to the
full repayment of the term loans provided by certain funds and accounts managed by Oaktree Capital Management, L.P. (the “Term Loans”) during 2020 as
further described in Note 8 of the accompanying notes to the consolidated financial statements in this Annual Report on Form 10-K

Loss on derivative liabilities for our Scilex segment for the year ended December 31, 2021 totaled $0.3 million and was primarily attributed to

revised probabilities and revised sales forecasts as further described in Note 3 of the accompanying notes to the consolidated financial statements in this
Annual Report on Form 10-K. Gain on derivative liabilities for our Scilex segment for the year ended December 31, 2020 totaled $0.8 million and was
primarily attributed to revised probabilities and revised sales forecasts as further described in Note 3 of the accompanying notes to the consolidated
financial statements in this Annual Report on Form 10-K

Loss on Marketable Investments. Loss on marketable investments reflects $39.8 million in unrealized losses related to the change in fair value of our
shares of Celularity Inc. and $24.1 million of realized gains from the sale of our shares of ImmunityBio, Inc. during the year ended December 31, 2021. We
recorded approximately $0.7 million in realized gains related to other investments during the year ended December 31, 2021. During the year ended
December 31, 2020, we did not have any marketable investments.

Scilex Notes principal increase. Actual cumulative net sales of ZTlido from the issue date of the Scilex Notes through December 31, 2021 did not

equal or exceed 95% of a predetermined target sales threshold for such period, which resulted in a $28.0 million increase in the principal amount of the
Scilex Notes, effective February 15, 2022. As a result, we recorded the increase of $28.0 million in principal and non-operating expense at December 31,
2021.

Interest expense. Interest expense for the years ended December 31, 2021 and 2020 was $10.2 million and $20.2 million, respectively. The decrease
resulted primarily from a decrease in interest expense associated with the term loans with Oaktree Capital Management L.P. and affiliates, which were fully
repaid in the year ended December 31, 2020. Interest income was immaterial for both periods.

Loss on debt extinguishment. Loss on debt extinguishment for the year ended December 31, 2021 was $6.7 million and was attributable to the

repurchases of the outstanding principal on the Scilex Notes, and was partially offset by short-term debt forgiveness. Loss on debt extinguishment for the
year ended December 31, 2020 was $51.9 million and was attributed to the repayments of outstanding principal on the Term Loans.

Income tax benefit. Income tax benefit for the year ended December 31, 2021 and 2020 was $33.5 million and $2.0 million, respectively. The
increase in the year ended December 31, 2021 was primarily due to deferred tax liabilities recognized from the ACEA acquisition resulting in a release of
valuation allowance in 2021 compared to 2020.

Loss on equity method investments. Loss on equity investments for the year ended December 31, 2021 was $0.1 million compared to a loss on equity

investments of $5.8 million for the year ended December 31, 2020. The loss was attributed to the recognition of our portion of the net loss or net income
from our equity method investments. During the year ended December 31, 2020, we also recorded an impairment loss of approximately $3.8 million
related to an equity method investment for which we determined the investment’s value was no longer supportable. (See Note 5 of the accompanying notes
to consolidated financial statements in this Annual Report on Form 10-K).

Net loss. Net loss for the year ended December 31, 2021 was $429.1 million as compared to a net loss of $314.4 million for 2020.

Comparison of the Years Ended December 31, 2020 and 2019

For a discussion regarding our financial condition and results of operations for the year ended December 31, 2020 as compared to the year ended
December 31, 2019, please refer to the discussion under the heading “Results of Operations— Comparison of the Years Ended December 31, 2020 and
2019” in Item 7 of our Annual Report on Form 10-K for the fiscal year ended December 31, 2020, filed with the Securities and Exchange Commission (the
“SEC”) on February 19, 2021.

Liquidity and Capital Resources

As of December 31, 2021, we had $36.7 million in cash and cash equivalents attributable in part to proceeds from the following debt and equity

financing arrangements:

Debt Financings

ACEA Significant Debt Arrangements

At the closing of the transactions contemplated by the Agreement and Plan of Merger, dated as of April 2, 2021, by and among us, AT Merger Sub,

Inc., an exempted company incorporated with limited liability in the Cayman Islands and our now wholly owned subsidiary, ACEA, and Fortis Advisors
LLC, as representative of the shareholders of ACEA and as a result thereof, on June 1, 2021, we, as the indirect parent to Hangzhou ACEA Pharmaceutical
Research Co., Ltd. (“ACEA Hangzhou”) and Zhejiang ACEA Pharmaceutical Co., Ltd. (“ACEA Zhejiang”), each of which are indirect subsidiaries of
ACEA, succeeded to the financial obligations of ACEA Hangzhou and ACEA Zhejiang, each of whom are parties to agreements with ACEA Bio
(Hangzhou) Co., Ltd. (“ACEA Bio”) (an entity unrelated to ACEA Hangzhou and ACEA Zhejiang) as set forth below.

Pursuant to that certain contract, dated as of August 15, 2018, between ACEA Hangzhou and ACEA Bio, ACEA Hangzhou borrowed an aggregate
of approximately $29.1 million (184,600,000 RMB) from ACEA Bio in a series of loans thereunder (the “Contract”). Each loan under the Contract is for a
period of 10 years and the maturity dates thereof range from August 15, 2023 to August 15, 2028. Each loan is interest free for the first five years, after
which time the interest rate is 5.39% per annum.

The outstanding principal amount under the Contract as of December 31, 2021 is $29.1 million. As a part of the preliminary purchase price

allocation, we estimated the fair value of the Contract to be approximately $17.1 million.

2018 Oaktree Term Loan Agreement

In November 2018, we entered into a Term Loan Agreement (the “Loan Agreement”) with certain funds and accounts managed by Oaktree Capital

Management, L.P. (collectively, the “Lenders”) and Oaktree Fund Administration, LLC, as administrative and collateral agent, for an initial term loan of
$100.0 million (the “Initial Loan”). In May 2019, we entered into an amendment to the Loan Agreement, under which terms the Lenders agreed to make
available to us $20.0 million (collectively, with the Initial Loan, the “Term Loans”). During the year ended December 31, 2020, we repaid $120.0 million
of the outstanding principal under the Term Loans plus approximately $9.4 million of related prepayment premium, exit fees and accrued interest thereon.

Scilex Notes

Scilex Pharma entered into purchase agreements (the “2018 Purchase Agreements”) with certain investors (collectively, the “Scilex Note

Purchasers”) and us. Pursuant to the 2018 Purchase Agreements, on September 7, 2018, Scilex Pharma issued and sold to

the Scilex Note Purchasers senior secured notes due 2026 in an aggregate principal amount of $224.0 million (the “Scilex Notes”) for an aggregate
purchase price of $140.0 million (the “Scilex Notes Offering”). In connection with the Scilex Notes Offering, Scilex Pharma also entered into an Indenture
(the “Indenture”) governing the Scilex Notes with U.S. Bank National Association, a national banking association, as trustee and collateral agent, and us.
Pursuant to the Indenture, we agreed to irrevocably and unconditionally guarantee, on a senior unsecured basis, the punctual performance and payment
when due of all obligations of Scilex Pharma under the Indenture.

We identified a number of embedded derivatives that require bifurcation from the Scilex Notes and were separately accounted for in the

consolidated financial statements as derivative liabilities. Certain of these embedded features include default interest provisions, contingent rate increases,
contingent put options, optional and automatic acceleration provisions and tax indemnification obligations. The fair value of the derivative liabilities
associated with the Scilex Notes was estimated using the discounted cash flow method under the income approach combined with a Monte Carlo
simulation model. This involves significant Level 3 inputs and assumptions, including a risk adjusted net sales forecast, an effective debt yield, estimated
marketing approval probabilities for SP-103 and an estimated probability of an initial public offering by Scilex Holding that satisfies certain valuation
thresholds and timing considerations. We re-evaluate this assessment each reporting period.

The 2018 Purchase Agreements and Indenture provide that, upon the occurrence of an event of default, the lenders thereunder may, by written notice

to us, declare all of the outstanding principal and interest under the Indenture immediately due and payable. For purposes of the Indenture, an event of
default includes, among other things, (i) a failure to pay any amounts when due under the Indenture, (ii) a breach or other failure to comply with the
covenants (including financial, notice and reporting covenants) under the Indenture, (iii) a failure to make any payment on, or other event triggering an
acceleration under, other material indebtedness of us, and (iv) the occurrence of certain insolvency or bankruptcy events (both voluntary and involuntary)
involving us or certain of our subsidiaries. We are subject to certain customary default clauses under the Indenture and are in compliance with the event of
default clauses under the Indenture.

On December 14, 2020, we, Scilex Pharma, U.S. Bank National Association, a national banking association, as trustee (the “Trustee”) and collateral

agent, and the beneficial owners of the Scilex Notes and the Scilex Note Purchasers entered into a Consent Under and Amendment No. 3 to Indenture and
Letter of Credit (the “Amendment”), which amended: (i) the Indenture, and (ii) the Letter of Credit.

On December 14, 2020, and in connection with the Amendment, the aggregate $45.0 million in restricted funds held in previously established
reserve and collateral accounts were released and Scilex Pharma utilized such funds to repurchase an aggregate of $45.0 million in principal amount of the
Scilex Notes. Scilex Pharma also repurchased $20.0 million in principal amount of the Scilex Notes in each of December 2020, February 2021 and April
2021.

Actual cumulative net sales of ZTlido from the issue date of the Scilex Notes through December 31, 2021 did not equal or exceed 95% of a

predetermined target sales threshold for such period, which resulted in a $28.0 million increase in the principal amount of the Scilex Notes, effective
February 15, 2022. As a result, we recorded the increase of $28.0 million in principal and non-operating expense at December 31, 2021.

Effective February 14, 2022, Scilex Pharma issued a draw notice to us under the Letter of Credit as required under the terms of the Indenture
because actual cumulative net sales of ZTlido from the issue date of the Scilex Notes through December 31, 2021 were less than a specified sales threshold
for such period, and we paid to Scilex Pharma $35,000,000 in a single lump-sum amount as a subordinated loan. Per the terms of the Amendment, in
February 2022, Scilex Pharma repurchased Scilex Notes from the holders thereof on a pro rata basis in an aggregate amount equal to the lesser of $20.0
million at a purchase price in cash equal to 100% of the principal amount thereof.

Bridge Loan Agreement

On February 16, 2022, we entered into a Bridge Loan Agreement between us, as borrower, and B. Riley Commercial Capital, LLC, as lender (the
“Lender”), pursuant to which we borrowed $45.0 million from the Lender (the “Bridge Loan”). For services rendered in connection with originating and
arranging the Bridge Loan, we agreed to pay to B. Riley Securities, Inc., an affiliate of the Lender, an upfront fee equal to four percent of the principal
amount of the Bridge Loan. The Bridge Loan bears no interest and will mature on June 16, 2022. Upon the occurrence and during the continuance of an
“Event of Default” under the Loan Agreement, the Bridge Loan shall bear interest at the rate of 15% per annum.

Marketable Investments

On March 9, 2021, NantKwest, Inc. and ImmunityBio completed their previously announced 100% stock-for-stock merger (the “ImmunityBio

Merger”). The combined company operates under the name ImmunityBio, Inc. and its shares of common stock commenced trading on the Nasdaq Global
Select Market on March 10, 2021 under the new ticker, “IBRX”. The former stockholders of ImmunityBio were entitled to receive 0.8190 shares of
common stock of the combined company for each outstanding share of ImmunityBio common stock held immediately prior to the ImmunityBio Merger.
Prior to the closing of the ImmunityBio Merger, we owned 10,000,000 shares of common stock of ImmunityBio, and we therefore received 8,190,000
shares of common stock of the post-merger company.

Prior to the ImmunityBio Merger, our investment in ImmunityBio was historically included as an equity investment in our consolidated balance

sheets and accounted for as an equity security without a readily determinable fair value. As of the completion of the ImmunityBio Merger, we accounted
for our investment in ImmunityBio as an equity investment with a readily determinable fair value and reclassified our investment in ImmunityBio to
marketable investments within our consolidated balance sheets. The investment in ImmunityBio was classified as a current asset because the investment
was liquidated to finance our current operations. In connection with the change in fair value of our investment in ImmunityBio, we recorded a realized gain
on marketable investments of $24.1 million during the year ended December 31, 2021. We sold 8,190,000 shares of ImmunityBio common stock during the
year ended December 31, 2021 for net proceeds to us of $124.0 million. We had no remaining shares of ImmunityBio common stock as of December 31,
2021.

On July 16, 2021, Celularity Inc. (“Pre-Merger Celularity”), a company of which we held an equity interest, completed its previously announced

merger with GX Acquisition Corp. (the “Celularity Merger”). Following the completion of the Celularity Merger, the combined, publicly traded company
formerly known as GX Acquisition Corp. was renamed Celularity Inc. (“Celularity”) and its Class A common stock commenced trading on the Nasdaq
Capital Market on July 19, 2021 under the ticker “CELU”. In connection with the Celularity Merger, all outstanding shares of Series A Preferred Stock of
Pre-Merger Celularity were converted into shares of Pre-Merger Celularity common stock and then each share of Pre-Merger Celularity common stock was
converted into the right to receive shares of Class A common stock of the post-merger company. We received 19,922,124 shares of Class A common stock
of the post-merger company in the Celularity Merger. We also purchased an aggregate of 500,000 shares of Class A common stock of Celularity for an
aggregate purchase price of $5,000,000 in a private placement transaction that closed on July 16, 2021 concurrently with the closing of the Celularity
Merger. Our investment in Celularity has historically been accounted for as an equity security without a readily determinable fair value. As of the trading
commencement date, we account for our investment in Celularity as an equity security with a readily determinable fair value. As of December 31, 2021, we
owned 20,422,124 shares of Class A common stock of Celularity. 19,922,124 shares of the Class A Common Stock of Celularity held by us are subject to
transfer restrictions until the earliest to occur of (i) 365 days after July 16, 2021; (ii) the first day after the date on which the closing price of the Class A

trading days within any 30-trading day period commencing at least 150 days after July 16, 2021; or (iii) the date on which Celularity completes a
liquidation, merger, capital stock exchange, reorganization or other similar transaction that results in all of Celularity’s public shareholders having the right
to exchange their Class A Common Stock for cash, securities or other property, subject to certain exceptions.

Equity Financings

At-the-Market Sales Agreement

On April 27, 2020, we entered into a Sales Agreement (the “Sales Agreement”) with A.G.P./Alliance Global Partners, as sales agent (the “Agent”),

pursuant to which we could offer and sell through or to the Agent up to $250.0 million in shares of its common stock (the “Shares”). On December 4, 2020,
we entered into Amendment No. 1 (the “December 2020 Amendment”) to the Sales Agreement, which amended the Sales Agreement to provide that we
could offer and sell, from time to time, through or to the Agent, up to an additional $450.0 million in shares of our common stock, such that we could offer
and sell up to an aggregate of $700.0 million in shares of our common stock pursuant to the Sales Agreement, as amended by the December 2020
Amendment (the “Original Amended Sales Agreement”).

On December 3, 2021, we amended and restated the Original Amended Sales Agreement to include Cantor Fitzgerald & Co., B. Riley Securities,

Inc. and H.C. Wainwright & Co., LLC as additional sales agents for our “at the market offering” program (the “Amended and Restated Sales Agreement”).

On December 23, 2021, we entered into Amendment No. 1 (the “December 2021 Amendment”) to the Amended and Restated Sales Agreement,

with Cantor Fitzgerald & Co., B. Riley Securities, Inc. and H.C. Wainwright & Co., LLC (the “Sales Agents”).

The December 2021 Amendment amended the Amended and Restated Sales Agreement to provide that we may offer and sell, from time to time,

through or to the Sales Agents, as sales agents and/or principals, up to an additional $5,000,000,000 in shares of our common stock (the “Additional
Shares”), such that we may offer and sell up to an aggregate of $5,442,943,290 in shares of our common stock (the “Offering”) pursuant to the Amended
and Restated Sales Agreement, as amended by the December 2021 Amendment (the “Amended Sales Agreement”), inclusive of $442,943,290 in shares
sold pursuant to the Original Amended Sales Agreement and the Amended and Restated Sales Agreement through December 22, 2021. Any Additional
Shares offered and sold in the Offering will be issued pursuant to our shelf registration statement on Form S-3ASR (the “Registration Statement”), which
became automatically effective upon filing with the SEC on December 23, 2021. The Additional Shares may be offered only by means of a prospectus
forming a part of the Registration Statement.

Subject to the terms and conditions of the Amended Sales Agreement, each Sales Agent will use its commercially reasonable efforts to sell the
shares of our common stock from time to time, based upon our instructions. Under the Amended Sales Agreement, the Sales Agents may sell the shares of
our common stock by any method permitted by law deemed to be an “at the market offering” as defined in Rule 415 promulgated under the Securities Act
of 1933, as amended.

We have no obligation to sell any shares of our common stock pursuant to the Amended Sales Agreement, and may at any time suspend offers under

the Amended Sales Agreement. The Offering will terminate upon (i) the election of the Sales Agents upon the occurrence of certain adverse events, (ii)
three business days’ advance notice from us to the Sales Agents or a Sales Agent (with respect to itself) to us, or (iii) the sale of all $5,442,943,290.81 of
shares of our common stock pursuant thereto.

Under the terms of the Amended Sales Agreement, the Sales Agents will be entitled to a commission at an initial fixed rate of 3.0% of the gross
proceeds from each sale of shares of our common stock under the Amended Sales Agreement, which percentage may be adjusted (but not above 3.0%)
based on the aggregate amount of securities sold by the Sales Agents pursuant to the Amended Sales Agreement.

We currently intend to use any additional net proceeds from the Offering for working capital and general corporate purposes, which may include

capital expenditures, research and development expenditures, regulatory affairs expenditures, clinical trial expenditures, acquisitions of new technologies
and investments, business combinations and the repayment, refinancing, redemption or repurchase of indebtedness or capital stock. We also may use a
portion of the net proceeds to repurchase or redeem a portion or all of the Scilex Notes.

During the year ended December 31, 2021, we sold an aggregate of 21,085,014 shares of our common stock pursuant to the Original Amended Sales

Agreement and the Amended Sales Agreement for aggregate net proceeds to us of approximately $175.6 million.

Universal Shelf Registration Statement

On December 23, 2021, we filed an automatic universal shelf registration statement on Form S-3 (the “WKSI Shelf Registration Statement”) with

the SEC as a well-known seasoned issuer as defined in Rule 405 under the Securities Act. The WKSI Shelf Registration Statement provides us with the
ability to offer an indeterminate amount of securities, including equity and other securities as described in the WKSI Shelf Registration Statement. Pursuant
to the WKSI Shelf Registration Statement, we may offer such securities from time to time and through one or more methods of distribution, subject to
market conditions and our capital needs. Specific terms and prices will be determined at the time of each offering under a separate prospectus supplement,
which will be filed with the SEC at the time of any offering. In connection with the WKSI Shelf Registration Statement, we entered into the Amended
Sales Agreement (discussed above) and included in the WKSI Shelf Registration Statement a prospectus covering $5,000,000,000 of shares of our common
stock issuable pursuant to the Amended Sales agreement.

Contingent Consideration

We have contingent consideration obligations in connection with certain acquisition and licensing transactions that are contingent upon achieving

certain specified milestones or the occurrence of certain events, including those described within the accompanying notes to the consolidated financial
statements of this Form 10-K. Upon the achievement of such milestones or the occurrence of such events, we will be obligated to make certain cash or
stock payments in accordance with the terms of such acquisition and license agreements.

Use of Cash

Cash Flows from Operating Activities. Net cash used for operating activities was $281.8 million for 2021 as compared to $159.5 million for 2020.

Net cash used reflects the cash spent on our research activities and cash spent to support the commercial launch of our products.

We expect to continue to incur substantial and increasing losses and negative net cash flows from operating activities as we seek to expand and

support our clinical and preclinical development and research activities, support the commercial launch of our products and fund our joint ventures,
collaborations and other third-party agreements.

Cash Flows from Investing Activities. Net cash provided by investing activities was $79.8 million for the year ended December 31, 2021 and was

attributed to proceeds received of $124.8 million from sales of marketable investments. We also spent approximately $35.3 million related to various
investments in new technologies and preclinical programs, $0.8 million in connection with the acquisition of ACEA, net of cash acquired, and
approximately $8.9 million primarily attributed to expenditures on laboratory equipment. During the year ended December 31, 2020, net cash used by
investing activities was $39.9 million. We invested approximately $31.1 million in licensing arrangements, invested approximately $2.3 million in new
technologies and preclinical programs and spent approximately $6.5 million on equipment and building improvements.

Cash Flows from Financing Activities. Net cash provided by financing activities was $181.3 million for 2021 as compared to $174.2 million for
2020. During the year ended December 31, 2021, we received $201.8 million from equity offerings, proceeds from short-term debt of $49.7 million and
proceeds of $15.4 million from common stock issuances and warrant exercises. During the year ended December 31, 2021, we repaid $45.9 million in
principal amount of the Scilex Notes, of which $32.7 million was attributed to principal included within financing activities and $13.1 million was
attributed to principal included in operating activities. We also repaid $53.0 million in other short-term debt. During the year ended December 31, 2020, we
received $317.9 million from equity offerings, proceeds from short-term debt of $18.6 million and proceeds of $98.4 million from common stock issuances
and warrant exercises. During the year ended December 31, 2020, we repaid $120.0 million of outstanding principal under the Term Loans, paid $6.3
million of related exit and prepayment fees thereon, made payments of $69.8 million on the Scilex Notes and repaid $9.4 million in short-term debt. We
also paid $55.0 million related to the Semnur Share Exchange as further described in Note 7 of the accompanying notes to the consolidated financial
statements in this Annual Report on Form 10-K.

Future Liquidity Needs. We have principally financed our operations through underwritten public offerings and private debt and equity financings,
as we have not generated any significant product related revenue from our principal operations to date. We will need to raise additional capital before we
exhaust our current cash resources in order to continue to fund our research and development, including our plans for clinical and preclinical trials and new
product development, as well as to fund operations generally. We will seek to raise additional funds through various potential sources, such as equity and
debt financings or through corporate collaboration, grant agreements and license agreements. We can give no assurances that we will be able to secure such
additional sources of funds to support our operations, or, if such funds are available to us, that such additional financing will be sufficient to meet our
needs. These conditions, among others, raise substantial doubt about our ability to continue as a going concern.

We cannot be certain that additional funding will be available on acceptable terms, or at all. If we issue additional equity securities to raise funds, the

ownership percentage of existing stockholders would be reduced. New investors may demand rights, preferences or privileges senior to those of existing
holders of common stock. If we are unable to raise additional capital in sufficient amounts or on terms acceptable to us, we may have to significantly delay,
scale back or discontinue the development or commercialization of one or more of our product candidates. We may also seek collaborators for one or more
of our current or future product candidates at an earlier stage than otherwise would be desirable or on terms that are less favorable than might otherwise be
available. These factors raise substantial doubt about our ability to continue as a going concern. Our financial statements and related notes thereto included
elsewhere in this Annual Report on Form 10-K do not include any adjustments that might result from the outcome of these uncertainties.

We anticipate that we will continue to incur net losses into the foreseeable future as we: (i) advance our product pipeline and other product
candidates into clinical trials, (ii) continue our development of, and seek regulatory approvals for, our product candidates in clinical trials, (iii) expand our
corporate infrastructure, and (iv) incur our share of joint venture and collaboration costs for our products and technologies.

Uses of Cash. We have and plan to expand our business and intellectual property portfolio through the acquisition of new businesses and

technologies as well as entering into licensing arrangements.

Material Cash Requirements

accompanying notes to the consolidated financial statements in this Annual Report on Form 10-K.
In connection with the acquisition of ACEA as further discussed in Note 7, we recorded long term contingent consideration of $123.8 million as
of December 31, 2021.

Critical Accounting Estimates

Our consolidated financial statements are prepared in accordance with U.S. GAAP. The preparation of these consolidated financial statements
requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, expenses and related disclosures. We evaluate
our estimates and assumptions on an ongoing basis. Our estimates are based on historical experience and various other assumptions that we believe to be
reasonable under the circumstances. Our actual results could differ from these estimates.

We believe the following accounting policies and estimates are most critical to aid in understanding and evaluating our reported financial results.

Revenue Recognition. Our revenues are generated from product revenues, the sale of customized reagents and other materials, contract
manufacturing services, grant revenue and other service revenues. We do not have significant costs associated with costs to obtain contracts with our
customers. Substantially all of our revenues and accounts receivable result from contracts with customers.

We recognize revenue when control of the products is transferred to the customers in an amount that reflects the consideration we expect to receive

from the customers in exchange for those products and services. This process involves identifying the contract with a customer, determining the
performance obligations in the contract and the contract price, allocating the contract price to the distinct performance obligations in the contract and
recognizing revenue when the performance obligations have been satisfied. A performance obligation is considered distinct from other obligations in a
contract when it provides a benefit to the customer either on its own or together with other resources that are readily available to the customer and is
separately identified in the contract. We consider a performance obligation satisfied once we have transferred control of a good or service to the customer,
meaning the customer has the ability to use and obtain the benefit of the good or service. We recognize revenue for satisfied performance obligations only
when no significant reversals are expected. (See Note 1 of the accompanying notes to the consolidated financial statements in this Annual Report on Form
10-K).

Investments in Other Entities. We hold a portfolio of investments in equity securities. Investments in entities over which we have significant

influence but not a controlling interest are accounted for using the equity method, with our share of earnings or losses reported in loss on equity
investments. Our other equity investments are carried at cost, less impairment, plus or minus changes resulting from observable price changes in orderly
transactions for identical or similar investments.

All investments are reviewed on a regular basis for possible impairment. If an investment’s fair value is determined to be less than its net carrying

value and the decline is determined to be other-than-temporary, the investment is written down to its fair value. Such an evaluation is judgmental and
dependent on specific facts and circumstances. Factors considered in determining whether an other-than-temporary decline in value has occurred include:
the magnitude of the impairment and length of time that the estimated market value was below the cost basis; financial condition and business prospects of
the investee; our intent and ability to retain the investment for a sufficient period of time to allow for recovery in market value of the investment; issues that
raise concerns about the investee’s ability to continue as a going concern; any other information that we may be aware of related to the investment. We do
not report the fair value of our equity investments in non-publicly traded companies because it is not readily determinable.

Debt, Including Debt With Detachable Warrants. Debt with detachable warrants is evaluated for the classification of warrants as either equity

instruments, derivative liabilities, or liabilities depending on the specific terms of the warrant agreement. In circumstances in which debt is issued with
equity-classified warrants, the proceeds from the issuance of convertible debt are first allocated to the debt and the warrants at their relative estimated fair
values. The portion of the proceeds so allocated to the warrants are accounted for as paid-in capital and a debt discount. The remaining proceeds, as further
reduced by discounts created by the bifurcation of embedded derivatives and beneficial conversion features, are allocated to the debt. We account for debt
as liabilities measured at amortized cost and amortize the resulting debt discount from the allocation of proceeds, to interest expense using the effective
interest method over the expected term of the debt instrument. We consider whether there are any embedded features in debt instruments that require
bifurcation and separate accounting as derivative financial instruments pursuant to Financial Accounting Standards Board (“FASB”) Accounting Standards
Codification (“ASC”) Topic 815, Derivatives and Hedging. Embedded features that require bifurcation are initially and subsequently measured at fair
value. See Note 3 of the accompanying notes to the consolidated financial statements in this Annual Report on Form 10-K for additional discussion on the
derivative liabilities associated with embedded features in our debt instruments.

If the amount allocated to the convertible debt results in an effective per share conversion price less than the fair value of our common stock on the
commitment date, the intrinsic value of this beneficial conversion feature is recorded as a discount to the convertible debt with a corresponding increase to
additional paid in capital. The beneficial conversion feature discount is equal to the difference between the effective conversion price and the fair value of
our common stock at the commitment date, unless limited by the remaining proceeds allocated to the debt.

We may enter financing arrangements, the terms of which involve significant assumptions and estimates, including future net product sales, in

determining interest expense, amortization period of the debt discount, as well as the classification between current and long-term portions. In estimating
future net product sales, we assess prevailing market conditions using various external market data against our anticipated sales and planned commercial
activities. Consequently, we impute interest on the carrying value of the debt and record interest expense using an imputed effective interest rate. We
reassess the expected payments each reporting period and account for any changes through an adjustment to the effective interest rate on a prospective
basis, with a corresponding impact to the classification of our current and long-term portions.

Intangible assets. In order to estimate the fair value of our identifiable intangible assets and other long-lived assets, we primarily use an income

approach, using the present value of estimated future cash flows from those assets. The key assumptions that we use in our discounted cash flow model are
the amount and timing of estimated future cash flows to be generated by the asset over an extended period of time and a rate of return that considers the
relative risk of achieving the cash flows, the time value of money, and other factors that a willing market participant would consider. Significant judgment
is required to estimate the amount and timing of future cash flows and the relative risk of achieving those cash flows.

Contingent consideration. The fair value of contingent consideration liabilities assumed in business combinations is recorded as part of the purchase

price consideration of the acquisition and is determined using a discounted cash flow model or Monte Carlo simulation model. The significant inputs of
such models are not observable in the market, such as certain financial metric growth rates, volatility rates, projections associated with applicable
milestones, discount rates and the related probabilities and payment structure in the contingent consideration arrangement. Fair value adjustments to
contingent consideration liabilities are recorded through operating expenses in the consolidated statement of operations. Contingent consideration
arrangements assumed by an asset acquisition will be measured and accrued when such contingency is resolved.

Recent Accounting Pronouncements

Refer to Note 1 of the accompanying notes to the consolidated financial statements in this Annual Report on Form 10-K for a discussion of recent

accounting pronouncements.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk.

Interest Rate Risk. Our exposure to market risk is confined to our cash and cash equivalents and debt. We have cash and cash equivalents and invest

primarily in high-quality money market funds, which we believe are subject to limited credit risk. Due to the low risk profile of our investments, an
immediate 10% change in interest rates would not have a material effect on the fair market value of our portfolio. We do not believe that we have any
material exposure to interest rate risk arising from our investments and we do not use derivative financial instruments to hedge against interest rate risk.

We are not subject to interest rate risk on the Scilex Notes associated with our 2018 Purchase Agreements as repayment of the Scilex Notes is
determined by projected net sales as further discussed in Note 8 of the accompanying notes to the consolidated financial statements in this Annual Report
on Form 10-K. For the Scilex Notes, changes in interest rates will generally affect the fair value of the debt instrument, but not our earnings or cash flows.

Capital Market Risk. We currently do not have significant revenues from grants or sales and services and we have no product revenues from our

planned principal operations and therefore depend on funds raised through other sources. One source of funding is through future debt or equity offerings.
Our ability to raise funds in this manner depends upon, among other things, capital market forces affecting our stock price.

Beginning in 2021, we held investments in marketable investments with readily determinable fair values, which are included as current marketable

investments within our consolidated balance sheets. Our investment in these publicly traded equity securities is recorded at fair value and is subject to
market price volatility. Changes in the fair value of such investments are recorded in our consolidated statement of operations within loss on marketable
investments. A portion of our marketable investments is subject to certain transfer restrictions and is adjusted for a discount for lack of marketability as
further discussed in Note 3 and in Note 5 of the accompanying notes to consolidated financial statements in this Annual Report on Form 10-K. As of
December 31, 2021, a price change of 10 percent would increase or decrease the fair value of our current marketable investments by approximately $9.0
million in the aggregate.

Concentration Risk. During the fiscal years ended December 31, 2021, 2020 and 2019, sales to the sole customer and third-party logistics

distribution provider of Scilex Pharma, Cardinal Health, represented 100% of the net revenue of Scilex Pharma. This exposes us to concentration of
customer risk. We monitor the financial condition of the sole customer of Scilex Pharma, limit our credit exposure by setting credit limits, and did not
experience any credit losses for the years ended December 31, 2021, 2020 and 2019. As we continue to expand the commercialization of ZTlido, we are
not limited to the current customer and have the option of expanding our distribution network with additional distributors through establishing our own
affiliates, by acquiring existing third-party business or product rights or by partnering with additional third parties. We obtain our commercial supply of
ZTlido and our clinical supply of SP-103 exclusively from Oishi Koseido Co., Ltd. and ITOCHU CHEMICAL FRONTIER Corporation in Japan.

Item 8. Financial Statements and Supplementary Data.

Our consolidated financial statements and supplementary data required by this item are set forth at the pages indicated in Item 15(a)(1) and (a)(2),

respectively, of this Annual Report on Form 10-K.

Item 9. Changes in and Disagreements With Accountants on Accounting and Financial Disclosure.

None.

Item 9A. Controls and Procedures.

Disclosure Controls and Procedures

We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our reports filed under the

Securities Exchange Act of 1934, as amended (the “Exchange Act”), is recorded, processed, summarized and reported within the time periods specified in
the SEC’s regulations, rules and forms and that such information is accumulated and communicated to our management, including our principal officers, as
appropriate, to allow for timely decisions regarding required disclosure.

In designing and evaluating our disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well

designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management is required to apply its
judgment in evaluating the cost-benefit relationship of possible controls and procedures. As required by Rule 13a-15(b) promulgated by the SEC under the
Exchange Act, we carried out an evaluation, under the supervision and with the participation of our management, including our Principal Executive Officer
and Principal Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures as of the end of the period
covered by this Annual Report on Form 10-K. Based on the foregoing, our Principal Executive Officer and Principal Financial Officer concluded that our
disclosure controls and procedures were not effective as of the end of the period covered by this Annual Report on Form 10-K as a result of the material
weakness described below.

Management’s Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as defined in Rule 13a-15(f) and
15d-15(f) promulgated under the Exchange Act. Internal control over financial reporting is a process designed by, or under the supervision of, our Principal
Executive Officer and Principal Financial Officer and effected by our Board of Directors, management and other personnel, to provide reasonable
assurance regarding the reliability of financial reporting and the preparation of our financial statements for external purposes in accordance with U.S.
GAAP. Internal control over financial reporting includes policies and procedures that: (i) pertain to the maintenance of records that, in reasonable detail,
accurately and fairly reflect the transactions and dispositions of an issuer’s assets; (ii) provide reasonable assurance that transactions are recorded as
necessary to permit preparation of financial statements in accordance with U.S. GAAP, and that an issuer’s receipts and expenditures are being made only
in accordance with authorizations of its management and directors; and (iii) provide reasonable assurance regarding prevention or timely detection of
unauthorized acquisition, use or disposition of an issuer’s assets that could have a material effect on the consolidated financial statements. 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 the annual or interim financial statements will not be prevented or detected on a timely basis. Because of its inherent limitations,
internal control over financial reporting may not prevent or detect misstatements. Also, the application of any evaluation of effectiveness to future periods
is subject to the risk that controls may become inadequate because of changes in conditions, or that compliance with the policies or procedures may
deteriorate.

As required by Rule 13a-15(c) promulgated under the Exchange Act, our management, with the participation of our Principal Executive Officer and
Principal Financial Officer, evaluated the effectiveness of our internal control over financial reporting as of December 31, 2021. Management’s assessment
was based on criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control - Integrated Framework
(2013 Framework) (“COSO”). Based on management’s assessment, management has concluded that our internal control over financial reporting was not
effective as of December 31, 2021 due to the material weakness in our internal control over financial reporting, as follows: As previously disclosed on our
Current Report on Form 8-K filed with the Securities and Exchange Commission on January 7, 2022, our former Chief Financial Officer passed away
unexpectedly on January 6, 2022. As a result of our former Chief Financial Officer`s passing as well as other considerations, management concluded that
we did not employ sufficient accounting resources with appropriate experience and technical expertise to effectively execute controls over certain
judgmental accounting areas. As a result, certain of our control activities in the areas of revenue, business combinations, investments, debt, derivative
liabilities and leases did not operate effectively and have been deemed deficient and the combination of the aforementioned deficiencies represents a
material weakness in our internal control over financial reporting.

Ernst & Young, LLP, our independent registered public accounting firm, has issued a report on our internal control over financial reporting as of

December 31, 2021. See “Report of Independent Registered Public Accounting Firm – Opinion on Internal Control over Financial Reporting” beginning on
Page F-2 of this Annual Report on Form 10-K.

Planned Remediation of Material Weaknesses

As a result of the material weakness described above, we are in the process of implementing remediation measures, including, but not limited to,
hiring a Chief Financial Officer and other personnel with appropriate experience and technical expertise to effectively execute controls over judgmental
accounting areas. We believe that our remediation measures, if effectively implemented, will provide reasonable assurance regarding the reliability of
financial reporting and the preparation of our financial statements for external purposes in accordance with U.S. GAAP. Any failure to implement these
improvements to our internal control over financial reporting would result in a continued material weakness in our internal control and could impact our
ability to produce reliable financial reports, effectively manage the company or prevent fraud, and could potentially harm our business and our
performance.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting (as defined by Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during

the quarter ended December 31, 2021 that have materially affected, or are reasonably likely to materially affect, our internal control over financial
reporting. As identified above under “Management’s Report on Internal Control Over Financial

Reporting”, a material weakness was identified in our internal control over financial reporting as of December 31, 2021. Our plans for remediating such
material weakness, enumerated above, will constitute changes in our internal control over financial reporting, prospectively, when such remediation plans
are effectively implemented.

Inherent Limitations over Internal Controls

Our management, including our Principal Executive Officer and Principal Financial Officer, intends that our disclosure controls and procedures and

internal control over financial reporting are designed to provide reasonable assurance of achieving their objectives. However, our management does not
expect that our disclosure controls and procedures or our internal control over financial reporting will prevent all errors and all fraud. A control system, no
matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the
design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs.
Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of
fraud, if any, have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can
occur because of a simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more
people or by management override of the controls. The design of any system of controls also is based in part upon certain assumptions about the likelihood
of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions; over time,
controls may become inadequate because of changes in conditions, or the degree of compliance with policies or procedures may deteriorate. Because of the
inherent limitations in a cost effective control system, misstatements due to error or fraud may occur and not be detected.

Item 11. Executive Compensation.

Compensation Discussion and Analysis

Compensation Philosophy

The primary goals of our Board with respect to executive compensation are to attract and retain talented and dedicated executives, to tie annual and
long-term cash and stock incentives to achievement of specified performance objectives, and to create incentives resulting in increased stockholder value.
To achieve these goals, our Compensation Committee recommends to our Board executive compensation packages, generally comprising a mix of salary,
discretionary bonus and equity awards. Although we have not adopted any formal guidelines for allocating total compensation between equity
compensation and cash compensation, we have implemented and maintain compensation plans that tie a substantial portion of our executives’ overall
compensation to achievement of corporate goals.

Role of Compensation Consultant

The Compensation Committee has the power to engage independent advisors to assist it in carrying out its responsibilities. For 2021, through

August 2021, the Compensation Committee re-engaged Compensia, Inc. (“Compensia”), a national compensation consulting firm, as its compensation
consultant to review and advise on our compensation practices. The Compensation Committee assessed the independence of Compensia pursuant to SEC
rules and concluded that the work of Compensia has not raised any conflict of interest. In 2021, Compensia undertook the following projects for the
Compensation Committee:

•

June 2021—Evaluated the compensation arrangements for the Company’s chief executive officer against a comparable group of similar life
sciences companies and its own proprietary data; and

June 2021—Evaluated the compensation arrangements for the members of the Company’s Board of Directors against a comparable group of
similar life sciences companies and its own proprietary data.

With respect to the salary increase for our chief executive officer to $1,000,000 that was retroactive to January 1, 2021 and the increase in his target bonus
to 100%, each of which was approved by the Compensation Committee in June 2021, the comparable group of life sciences companies consisted of the
following companies, determined to: (i) generally have similar revenues as us;

(ii) generally have similar market capitalization as us, (iii) generally have similar operating income as us, and (iv) generally have the same number of
employees as us:

AbCellera Biologics Inc.

Acceleron Pharma Inc.

Allogene Therapeutics, Inc.

Arcus Biosciences, Inc.

Arrowhead Pharmaceuticals, Inc.

Dicerna Pharmaceuticals, Inc.

Fate Therapeutics, Inc.

Heron Therapeutics, Inc.

ImmunityBio, Inc.

ImmunoGen, Inc.

Inovio Pharmaceuticals, Inc.

MacroGenics, Inc.

Mersana Therapeutics, Inc.

Mirati Therapeutics, Inc.

Nektar Therapeutics

Quidel Corporation

SpringWorks Therapeutics, Inc.

Turning Point Therapeutics, Inc.

Twist BioScience Corporation

Vir Biotechnology, Inc.

Xencor, Inc.

In August 2021, the Compensation Committee engaged Prescient Healthcare Group (“Prescient”) as its compensation consultant. In August 2021,

Prescient conducted a competitive landscapes and compensation structures analysis for the Compensation Committee, which included an executive
compensation structure analysis for the Company’s chief executive officer, chief financial officer and non-employee directors.

With respect to the grant of an option to purchase 2,500,000 shares of our common stock to our chief executive officer in August 2021 and the salary

increase for our chief executive officer to $1,500,000 that was retroactive to January 1, 2021 and approved by the Compensation Committee in December
2021, the comparable group of life sciences companies consisted of the following companies that have approved products or product candidates that are
competitive with the Company’s products and product candidates:

Abbott Laboratories

AbbVie Inc.

Johnson & Johnson

Merck KGaA

Alexion Pharmaceuticals, Inc.

Merck Sharp & Dohme Corp.

Amgen Inc.

Arrowhead Pharmaceuticals, Inc.

AstraZeneca PLC

Bayer AG

Moderna, Inc.

Novartis AG

Pfizer Inc.

PTC Therapeutics, Inc.

BioHaven Pharmaceutical Holding Company Ltd.

Regeneron Pharmaceuticals, Inc.

Bristol-Myers Squibb Company

Roche Holding AG

Eli Lilly and Company

Gilead Sciences, Inc.

GlaxoSmithKline plc

Incyte Corporation

Sanofi

Takeda Pharmaceutical Company Limited

Teva Pharmaceutical Industries Limited

In 2021, Compensia and Prescient reviewed and advised the Compensation Committee on the matters described above.

In setting 2021 compensation, the Compensation Committee reviewed the competitive market analyses provided by Compensia in June 2021 and

Prescient in August 2021 and compared each named executive officer’s base salary, target annual performance bonus and equity compensation value,
separately and in the aggregate, to amounts paid to similarly-situated executives at our peer companies. The Compensation Committee believes that
targeting compensation towards similarly situated executives at our peer companies helps achieve the compensation objectives described above. However,
compensation for each named executive officer may vary from this range depending on other factors the Compensation Committee considers relevant, such
as internal pay equity among

our named executive officers or levels of authority, responsibility and experience of our named executive officers that exceed the norms for individuals
holding comparably-titled positions at other companies.

Elements of Compensation

We evaluate individual executive performance with a goal of setting compensation at levels our Board or any applicable committee thereof believes

are comparable with executives in other companies of similar size and stage of development while taking into account our relative performance and our
own strategic goals. The compensation received by our named executive officers consists of the following elements:

Base Salary

Base salaries for our executives are established based on the scope of their responsibilities and individual experience, taking into account

competitive market compensation paid by other companies for similar positions within our industry.

The Compensation Committee considers compensation data from the peer companies to the extent the executive positions at these companies are

considered comparable to our positions and informative of the competitive environment. Compensation data for our peer group were collected from
available proxy-disclosed data. This information was gathered and analyzed for the 25th, 50th and 75th percentiles for annual base salary, short-term
incentive pay elements and long-term incentive pay elements.

The amended and restated employment agreement between us and Dr. Ji, dated May 9, 2017, provided for an annual base salary for Dr. Ji of
$600,000, as may be adjusted from time to time. In May 2018, the Compensation Committee increased Dr. Ji’s annual base salary from $600,000 to
$670,000 with retroactive effect to January 1, 2018. Dr. Ji’s salary was not adjusted, and remained $670,000, during 2019. In June 2020, after considering a
competitive market analysis provided by Compensia in June 2020, the Compensation Committee increased Dr. Ji’s annual base salary to $700,000, with
retroactive effect to January 1, 2020. In June 2021, after considering the competitive market analysis provided by Compensia in June 2021, the
Compensation Committee increased Dr. Ji’s annual base salary to $1,000,000, with retroactive effect to January 1, 2021. Following discussions with Dr. Ji
regarding his compensation in the second half of 2021, culminating in a process rooted in the findings of the Prescient competitive analysis of two key
factors: (1) a detailed analysis of each member of the peer group’s pipeline of products in clinical trials (as defined from IND filing, Ph. I, Ph. II, Ph. III, up
to and including an NDA filing), and (2) a detailed competitive compensation analysis of a peer group with similar pipeline dynamics, and after
considering both the June 2021 competitive analysis from Compensia as well as the more expansive Prescient competitive analysis, in December 2021, the
Compensation Committee increased Dr. Ji’s annual base salary to $1,500,000, with retroactive effect to January 1, 2021.

The offer letter between us and Najjam Asghar, our former Senior Vice President and Chief Financial Officer, dated April 24, 2019, provided for an
annual base salary of $300,000, as could be adjusted from time to time. In October 2020, the Compensation Committee considered the competitive market
analysis provided by Compensia in June 2020 and increased Mr. Asghar’s annual base salary to $400,000, retroactive to August 18, 2020, the effective date
of his promotion to Senior Vice President and Chief Financial Officer. In March 2021, the Compensation Committee increased Mr. Asghar’s salary to
$450,000, with retroactive effect to January 1, 2021. The main drivers that the Compensation Committee considered in setting Mr. Asghar’s salary increase
were as follows: (1) the increase still fit comfortably within a reasonable range within the peer group in the June 2020 Compensia competitive analysis, and
(2) the Compensation Committee considered the increase important for both motivational and retention purposes. Mr. Asghar passed away on January 6,
2022.

Variable Pay

We design our variable pay programs to be both affordable and competitive in relation to the market. We monitor the market and adjust our variable

pay programs as needed. Our variable pay programs, such as our bonus program, are designed to motivate employees to achieve overall goals. Our
programs are designed to avoid entitlements, to align actual payouts with the actual results achieved, and to be easy to understand and administer.

Bonuses

For 2021, Dr. Ji’s target annual bonus was equal to 100% of his annual salary, which the Compensation Committee set in June 2021 after
considering the competitive market analysis provided by Compensia in June 2021. Our offer letter with Mr. Asghar provided that Mr. Asghar’s annual
target bonus was equal to 30% of his annual salary, which the Compensation Committee increased to 40% in October 2020 after considering the
competitive market analysis provided by Compensia in 2020 and Mr. Asghar’s promotion in August 2020. Mr. Asghar passed away on January 6, 2022.

As of the date of the filing of this Annual Report on Form 10-K, the Compensation Committee has not yet determined the annual bonus amount, if

any, that will be awarded Dr. Ji for 2021. We expect the Compensation Committee to assess 2021 performance and determine the 2021 annual bonus
awards for Dr. Ji in the second half of 2022. Once such annual bonus amount, if any, has been determined, we will, in accordance with Securities and
Exchange Commission rules and regulations, file a Current Report on Form 8-K or otherwise disclose the 2021 annual bonus amount within four business
days after the Compensation Committee has assessed 2021 performance and determined the 2021 annual bonus awards for Dr. Ji.

Equity-Based Incentives

Salaries and bonuses are intended to compensate our executive officers for short-term performance. We also have adopted an equity incentive

program intended to reward longer-term performance and to help align the interests of our named executive officers with those of our stockholders. We
believe that long-term performance is achieved through an ownership culture that rewards performance by our named executive officers through the use of
equity incentives. Our equity incentive plan has been established to provide our employees, including our named executive officers, with incentives to help
align those employees’ interests with the interests of our stockholders.

When making equity-award decisions, the Compensation Committee considers market data, the grant size, the forms of long-term equity
compensation available to it under our existing plans and the status of previously granted awards. The amount of equity incentive compensation granted
reflects the executives’ expected contributions to our future success. Existing ownership levels are not a factor in award determination, as the
Compensation Committee does not want to discourage executives from holding significant amounts of our stock.

Future equity awards that we make to our named executive officers will be driven by our sustained performance over time, our named executive
officers’ ability to impact our results that drive stockholder value, their level of responsibility, their potential to fill roles of increasing responsibility, and
competitive equity award levels for similar positions in comparable companies. Equity forms a key part of the overall compensation for each executive
officer and is evaluated each year as part of the annual performance review process and incentive payout calculation.

The amounts awarded to the named executive officers are based on the Compensation Committee’s subjective determination of what is appropriate

to incentivize the executives. Generally, the grants to named executive officers vest over: (i) a four-year period with 25% vesting on each anniversary of the
grant date, or (ii) a four-year period with 1/4 of the shares vesting on the first anniversary of the applicable vesting commencement date, and 1/48 of the
shares vesting thereafter on a monthly basis. All equity awards to our employees, including named executive officers, and to directors have been granted
and reflected in our financial statements, based upon the applicable accounting guidance, with the exercise price equal to the fair market value of one share
of common stock on the grant date.

In order to encourage a long-term perspective and to encourage key employees to remain with us, our stock options typically have annual vesting

over a four-year period and a term of ten years. Generally, vesting ends upon termination of services and exercise rights of vested options cease three
months after termination of services. Prior to the exercise of an option, the holder has no rights as a stockholder with respect to the shares subject to such
option, including voting rights and the right to receive dividends or dividend equivalents.

In August 2021, the Compensation Committee determined to grant to Dr. Ji a long-term equity based incentive in the form of an option to purchase

2,500,000 shares of our common stock, 25% of which shares shall vest on August 30, 2022 and 1/48th of which shall vest monthly thereafter. The
Compensation Committee considered the competitive market analysis provided by Prescient in August 2021 and other data in determining the number of
options granted to Dr. Ji, and also considered the following: Dr. Ji, having taken on the additional role as the head of research and development, had driven
a remarkable pipeline increase from five products in the clinic to 23 products in the clinic over the previous 18 month period, a major leap forward for the
company, especially in light of our lean company size of roughly 500 employees. This significant increase in pipeline productivity was the main driver for
this grant.

In March 2021, Mr. Asghar was granted long-term equity based incentives in the form of an option to purchase 100,000 shares of our common

stock, 25% of which shares were to vest on March 16, 2022 and 1/48th of which were to vest monthly thereafter, and a restricted stock award with respect
to 56,974 shares of our common stock that were to vest 1/4 annually from the date of grant. These grants were well within the Chief Financial Officer peer
group analysis provided by Compensia and the Compensation Committee believed that they were important for ongoing motivational purposes, and for
retention in an incredibly tight labor market. Mr. Asghar passed away on January 6, 2022, on which date the stock option and the restricted stock award
terminated unvested.

CEO Performance Award

On August 7, 2020, the Compensation Committee approved a grant to Dr. Ji of a 10-year CEO performance award tied solely to achieving market
capitalization milestones (the “CEO Performance Award”) which was approved by our stockholders at the 2020 Annual Meeting of Stockholders held on
October 16, 2020. The CEO Performance Award consists of a 10-year option to purchase an aggregate of 24,935,882 shares of our common stock, which
was equal to 10% of our outstanding shares of common stock on the day prior to the date of grant, and vests in ten tranches. Each of the ten tranches vests
only if a market capitalization milestone is achieved, which requires two market capitalization prongs to be met to achieve each milestone: (1) a six
calendar month trailing average (based on trading days); and (2) a 30-calendar day trailing average (based on trading days). To meet the first market
capitalization milestone, our current market capitalization must increase to $5.0 billion. For the next two milestones, our market capitalization must
continue to increase in additional $2.0 billion increments. For the three milestones thereafter, our market capitalization must increase in additional $3.0
billion increments. For the next three milestones thereafter, our market capitalization must increase in additional $4.0 billion increments. For the final
milestone, our market capitalization must increase by an additional $5.0 billion. Thus, for Dr. Ji to fully vest in the award, our market capitalization must
increase to $35.0 billion. The exercise price per share subject to the CEO Performance Award is $17.30, which is a 20% premium to the closing sales price
of our common stock on August 7, 2020, the date the CEO Performance Award was approved by the Compensation Committee. As of December 31, 2021,
none of the CEO Performance Award was vested.

Benefits Programs

We design our benefits programs to be both affordable and competitive in relation to the market while conforming with local laws and practices. We
monitor the market and local laws and practices and adjust our benefits programs as needed. We design our benefits programs to provide an element of core
benefits and, to the extent possible, offer options for additional benefits, be tax-effective for employees in each country and balance costs and cost sharing
between us and our employees.

Timing of Equity Awards

Only the Compensation Committee may approve stock option grants to our executive officers. Stock options are generally granted at meetings of the
Compensation Committee or pursuant to a unanimous written consent of the Compensation Committee. The exercise price of a newly granted option is the
closing price of our common stock on the date of grant.

Executive Equity Ownership

We encourage our executives to hold a significant equity interest in our company. However, we do not have specific share retention and ownership

guidelines for our executives.

Hedging Policy

Our Insider Trading and Window Period Policy prohibits our directors, officers and employees, and their family members, from engaging in hedging

transactions involving our securities.

Consideration of Advisory Votes to Approve the Compensation of our Named Executive Officers

We value the opinions of our stockholders, including as expressed through advisory votes to approve the compensation of our named executive

officers (“Say-on-Pay Votes”). In our most recent Say-On-Pay Vote, conducted at our 2021 annual meeting of stockholders, held on November 15, 2021,
our stockholders approved the compensation of our named executive officers on an advisory basis, with approximately 63.3% of the votes cast in favor of
the fiscal 2020 compensation of our named executive officers. In setting fiscal 2022 compensation, we will consider the outcome of the Say-on-Pay Vote
during our 2021 annual meeting of stockholders and will continue to consider the outcome of future Say-on-Pay Votes, as well as stockholder feedback
received throughout the year, when making compensation decisions for our executive officers.

Effect of Accounting and Tax Treatment on Compensation Decisions

In the review and establishment of our compensation programs, we consider the anticipated accounting and tax implications to us and our

executives.

Generally, Section 162(m) of the Code disallows public companies a tax deduction for federal income tax purposes of compensation in excess of $1

million paid to their chief executive officer and certain other specified officers in any taxable year. For tax years ending prior to December 31, 2017,
compensation in excess of $1 million could only be deducted if it was

“performance-based compensation” within the meaning of Section 162(m) of the Code or qualified for one of the other exemptions from the deduction
limit. The exemption from Section 162(m) of the Code’s deduction limit for performance-based compensation has been repealed, effective for taxable years
beginning after December 31, 2017, such that compensation paid to our covered officers (which now also includes our Chief Financial Officer) in excess of
$1 million will generally not be deductible unless it qualifies for transition relief applicable to certain arrangements in place as of November 2, 2017. We
seek to maintain flexibility in compensating our executives in a manner designed to promote our corporate goals and, therefore, while we are mindful of the
benefit of the full deductibility of compensation, our Compensation Committee has not adopted a policy requiring that any or all compensation to be
deductible. Our Compensation Committee may authorize compensation payments that are not fully tax deductible if we believe that such payments are
appropriate to attract and retain executive talent or meet other business objectives.

Role of Executives in Executive Compensation Decisions

The Board and our Compensation Committee generally seek input from our Chief Executive Officer, Dr. Ji, when discussing the performance of,

and compensation levels for, executives other than himself. The Compensation Committee also works with Dr. Ji and our Chief Financial Officer to
evaluate the financial, accounting, tax and retention implications of our various compensation programs. Neither Dr. Ji nor any of our other executives
participate in deliberations relating to his compensation.

Compensation Risk Management

We have considered the risk associated with our compensation policies and practices for all employees, and we believe we have designed our
compensation policies and practices in a manner that does not create incentives that could lead to excessive risk taking that would have a material adverse
effect on us for the following reasons:

•

We structure our compensation to consist of base salary, variable pay, equity-based pay and benefits. The base portion of compensation is
designed to provide a steady income regardless of our stock price performance so that executives do not feel pressured to focus exclusively
on stock price performance to the detriment of other important business measures. Our variable pay and equity-based pay programs are
designed to reward both short- and long-term corporate performance. For short-term performance, our variable pay programs are designed to
motivate employees to achieve overall goals. For long-term performance, our stock option awards generally vest over four years and are only
valuable if our stock price increases over time. We believe that these variable elements of compensation are a sufficient percentage of overall
compensation to motivate executives to produce superior short- and long-term corporate results, while the fixed element is also sufficiently
high that the executives are not encouraged to take unnecessary or excessive risks in doing so.

Our bonus program has been structured around attainment of overall corporate goals for the past several years and we have seen no evidence
that it encourages unnecessary or excessive risk taking.

The following table provides certain summary information concerning compensation awarded to, earned by or paid to each person who served as
our principal executive officer at any time during fiscal year 2021 and each person who served as our principal financial officer at any time during fiscal
year 2021 (collectively, the “named executive officers”). We did not have any other executive officers during fiscal year 2021.

of Compensation-Variable Pay-2021 Bonuses” above for a discussion of the target bonus amount for Dr. Ji for fiscal year 2021. We expect the
Compensation Committee to assess 2021 performance and determine the 2021 annual bonus award for Dr. Ji in the second half of 2022. Dr. Ji may
also be entitled to receive a bonus from Scilex Holding Company in connection with his role as its Executive Chairperson; however, the amount of
any such bonus has not yet been determined. Once such annual bonus amounts, if any, have been determined, we will, in accordance with Securities
and Exchange Commission rules and regulations, file a Current Report on Form 8-K or otherwise disclose the 2021 annual bonus amounts within
four business days after the Compensation Committee has assessed 2021 performance and determined the 2021 annual bonus awards for Dr. Ji.

Represents the fair market value of a share of our common stock, as determined by the Board, on the option’s grant date.

Shares subject to the option vest and become exercisable over a four-year period, with 1/4 of the shares vesting on the first anniversary of the
Vesting Commencement Date, and 1/48 of the shares vesting following each one-month period of the participant’s continued employment or
service with the Company thereafter.

62.5% of the shares subject to the option vested over a four-year period, with 1/4 of the shares vesting on the first anniversary of the Vesting
Commencement Date, and 1/48 of the shares vesting following each one-month period of the participant’s continued employment or service
with the Company thereafter. The remaining 37.5% of the shares subject to the option vested upon the consummation of a certain strategic
transaction.

Represents options granted by our subsidiary, Scilex Holding Company.

Reflects the CEO Performance Award, which is intended to compensate Dr. Ji over its 10-year maximum term and will vest only if certain
pre-established market capitalization milestones are achieved, which requires two market capitalization prongs to be met to achieve each
milestone: (1) a six-calendar month trailing average (based on trading days); and (2) a 30-calendar day trailing average (based on trading
days). For the first tranche to vest, Sorrento’s market capitalization has to increase to $5 billion. For the next two tranches to vest, Sorrento
must increase its market capitalization in additional $2 billion increments, then by increments of $3 billion for the three tranches after that,
then by increments of $4 billion for the next three tranches and a final increment of $5 billion for the final tranche—up to a total market
capitalization of $35 billion. For each tranche that is achieved, Dr. Ji will vest and earn the right to exercise the option for that number of
shares of Sorrento common stock that corresponds to approximately 1% of Sorrento’s total outstanding shares, calculated as of August 6,
2020. The option, to the extent vested, will be exercisable until August 7, 2030 (ten years from the date of

101

grant). The CEO Performance Award was approved by our stockholders at the 2020 Annual Meeting of Stockholders held on October 16,
2020. As of December 31, 2021, none of the CEO Performance Award was vested.

(6) Mr. Asghar passed away on January 6, 2022.

1/4thof the shares subject to the restricted stock unit award were to vest on each one year anniversary of the grant date.

Employment, Severance, Separation and Change in Control Agreements

Chief Executive Officer Amended and Restated Employment Agreement

On May 9, 2017, we entered into an Amended and Restated Employment Agreement (the “Restated Agreement”) with Dr. Ji. Pursuant to the
Restated Agreement, Dr. Henry Ji will continue to serve as our President and Chief Executive Officer for an initial term of three years commencing on May
9, 2017. Following this initial three year term, the Restated Agreement shall renew automatically for additional 12 month terms unless either we or Dr. Ji
provide written notice of non-renewal at least three months in advance of the expiration of the then-current term. The Restated Agreement supersedes and
replaces a prior employment agreement with Dr. Ji, dated September 21, 2012, as amended on October 18, 2012.

Pursuant to the Restated Agreement, Dr. Ji shall (i) receive an annual base salary (the “Annual Base Salary”) of $600,000, as may be adjusted from

time to time; (ii) be eligible to participate in an annual incentive program, with a target annual bonus incentive equal to 55% of his then-current Annual
Base Salary (the “Annual Bonus”); and (iii) receive employee benefits, paid personal leave and expense reimbursement in accordance with our policies. In
addition, Dr. Ji’s performance will be reviewed by the Board at least annually, and his Annual Base Salary, target Annual Bonus and any other
compensation will be subject to adjustment by the Board, provided that Dr. Ji’s Annual Base Salary and target Annual Bonus may not be adjusted
downward.

Pursuant to the Restated Agreement, we have the right to terminate Dr. Ji’s employment at any time with or without “cause” (as defined in the
Restated Agreement). In addition, Dr. Ji may resign with or without “good reason” (as defined in the Restated Agreement) upon 30 days’ written notice to
us. Under each such circumstance, Dr. Ji will be entitled to receive any accrued but unpaid base salary as of the date of termination or resignation, any
expenses owed to him and any amount accrued and arising from his participation in, or vested benefits accrued under, any employee benefit plans,
programs or arrangements, including any 401(k), profit sharing or pension plan (collectively, the “Termination Payments”).

In the event that Dr. Ji’s employment is terminated by us without “cause” or by our non-renewal of the term of the Restated Agreement, or by Dr. Ji
for “good reason,” in either case outside of a Change of Control Window (as defined below), then, subject to Dr. Ji’s timely execution and non-revocation
of a release in favor of us, Dr. Ji will be entitled to receive the following: (i) the Termination Payments; (ii) an amount equal to his then-current Annual
Base Salary, payable in a lump sum; (iii) an amount equal to his pro-rata then-current target Annual Bonus, payable in a lump sum; (iv) 12 months of health
insurance benefits for Dr. Ji and for his eligible dependents who were covered under our health insurance plans as of the date his employment was
terminated; and (v) one year of accelerated vesting of Dr. Ji’s then-outstanding awards of equity compensation, with performance-criteria deemed satisfied
at target.

If Dr. Ji’s employment is terminated without “cause” or by our non-renewal of the term of the Restated Agreement, or by Dr. Ji for “good reason,” in

either case during the period commencing three months prior to a Change of Control and ending 12 months after a Change of Control (as defined in the
Restated Agreement) (the “Change of Control Window”), then, subject to Dr. Ji’s timely execution and non-revocation of a release in favor of us, Dr. Ji will
be entitled to receive the following: (i) the Termination Payments; (ii) an amount equal to twice his then-current Annual Base Salary, payable in a lump
sum; (iii) an amount equal to twice his pro-rata then-current target Annual Bonus, payable in a lump sum; (iv) 24 months of health insurance benefits for
Dr. Ji and for his eligible

103

dependents who were covered under our health insurance plans as of the date his employment was terminated; and (v) accelerated vesting of Dr. Ji’s then-
outstanding awards of equity compensation, with performance-criteria deemed satisfied target.

The CEO Performance Award does not provide for automatic acceleration of vesting upon a change in control event; however, in the event of a
change of control, the achievement of the market capitalization milestones will be based on our market capitalization determined by the product of the total
number of outstanding shares of our common stock immediately before the change of control multiplied by the per share price (plus the per share value of
any other consideration) received by our stockholders in the change of control. Any portion of the CEO Performance Award that does not vest in
accordance with the above will be forfeited automatically as of immediately prior to the effective time of the change of control and never shall become
vested.

Former Chief Financial Officer Change of Control Severance Agreement

On November 5, 2020, we entered into a Change of Control and Severance Agreement (the “Severance Agreement”) with Mr. Asghar. Pursuant to

the Severance Agreement, if Mr. Asghar’s employment was terminated without “cause” or by Mr. Asghar for “good reason,” in either case during the
period commencing three months prior to a Change of Control (as defined in the Severance Agreement) and ending 12 months after a Change of Control,
then, subject to Mr. Asghar’s timely execution and non-revocation of a release in favor of us, Mr. Asghar would have been entitled to receive the following:
(i) an amount equal to his then-current annual base salary, payable in a lump sum; (ii) an amount equal to his then-current target annual bonus, payable in a
lump sum; (iii) 12 months of health insurance benefits for Mr. Asghar and for his eligible dependents who were covered under the Company’s health
insurance plans as of the date his employment was terminated; and (iv) accelerated vesting of Mr. Asghar’s then-outstanding awards of equity
compensation, with performance-criteria, if any, deemed satisfied at target. Mr. Asghar passed away on January 6, 2022 and this agreement is therefore no
longer in effect.

POTENTIAL PAYMENTS UPON TERMINATION OR CHANGE IN CONTROL

Other than the provisions of the executive severance benefits to which our named executive officers would be entitled to at December 31, 2021 (the
last trading day of the year) as set forth above, we have no liabilities under termination or change in control conditions. We do not have a formal policy to
determine executive severance benefits. Each executive severance arrangement is negotiated on an individual basis.

The tables below estimate the current value of amounts payable to our named executive officers that were serving as such as of the end of December
31, 2021 in the event that a termination of employment occurred on December 31, 2021 (the last trading day of the year). The closing price of our common
stock, as reported on the Nasdaq Capital Market, was $4.65 on December 31, 2021. The following tables exclude certain benefits, such as accrued vacation,
that are available to all employees generally. The actual amount of payments and benefits that would be provided can only be determined at the time of a
change in control and/or the named executive officer’s qualifying separation from the Company.

Outside Director Compensation Policy

Our outside director compensation policy in effect during 2021 provided that each non-executive director received a $55,000 annual cash retainer,

with the amount being increased to $78,000 for any Lead Director and $100,000 for any Board chairman. Further, the chairperson of each of our Audit,
Compensation and Corporate Governance and Nominating Committees received an additional annual cash retainer of $25,000. Other members of our
Audit, Compensation and Corporate Governance and Nominating Committees received an additional cash retainer of $10,000. In addition, each non-
executive director was entitled to receive an annual grant of a stock option to purchase 250,000 shares of common stock, which vests monthly over a period
of 48 months from the date of grant, subject to continued service through each vesting date. As a new director, Ms. Czerepak was granted an option to
purchase

105

100,000 shares of common stock, which vests monthly over a period of 12 months from the date of grant, subject to continued service through each vesting
date. Additionally, we reimbursed each outside director for reasonable travel expenses related to such director’s attendance at Board and committee
meetings.

Effective January 1, 2022, our Compensation Committee approved an amendment and restatement of our outside director compensation policy (the

“Amended Outside Director Compensation Policy”). Pursuant to the Amended Outside Director Compensation Policy, each non-executive director is
entitled to receive a $82,500 annual cash retainer, with the amount being increased to $117,000 for any Lead Independent Director or any Board
chairperson. Further, the chairperson of each of our Audit, Compensation and Corporate Governance and Nominating Committees is entitled to receive an
additional annual cash retainer of $37,500. Other members of our Audit, Compensation and Corporate Governance and Nominating Committees are
entitled to receive an additional cash retainer of $15,000. In addition, each non-executive director will be entitled to receive an annual grant of a stock
option to purchase 250,000 shares of common stock, which vests monthly over a period of 48 months from the date of grant, subject to continued service
through each vesting date. Additionally, we will reimburse each outside director for reasonable travel expenses related to such director’s attendance at
Board and committee meetings.

Other Compensation

We intend to provide benefits and perquisites for our named executive officers at levels comparable to those provided to other executive officers in

our industry. Our Board or any applicable committee thereof, in its discretion, may revise, amend or add to the benefits and perquisites of any named
executive officer as it deems it advisable and in the best interest of the Company and our stockholders.

Compensation Committee Interlocks and Insider Participation

Our Compensation Committee consists of two directors, each of whom is a non-employee director: Mr. Followwill and Dr. Wu. Dr. Wu serves as the
Chairperson of the Compensation Committee. During 2021, neither Mr. Followwill nor Dr. Wu was an officer or employee of ours, was formerly an officer
of ours or had any relationship requiring disclosure by us under Item 404 of Regulation S‑K. No interlocking relationship as described in Item 407(e)(4) of
Regulation S-K exists between any of our executive officers or Compensation Committee members, on the one hand, and the executive officers or
compensation committee members of any other entity, on the other hand, nor has any such interlocking relationship existed in the past.

Compensation Committee Report

The Compensation Committee has reviewed and discussed the Compensation Discussion and Analysis required by Item 402(b) of Regulation S-K
of the SEC’s rules and regulations with management and, based on such review and discussions, the Compensation Committee recommended to the Board
of Directors that the Compensation Discussion and Analysis be included in this Annual Report on Form 10-K.

Compensation Committee

Dr. Yue Alexander Wu

Mr. Dorman Followwill

The foregoing Compensation Committee Report shall not be deemed to be “soliciting material,” deemed “filed” with the SEC or subject to the

liabilities of Section 18 of the Exchange Act. Notwithstanding anything to the contrary set forth in any of the Company’s previous filings under the
Securities Act of 1933, as amended, or the Exchange Act that might incorporate by reference future filings, including this Annual Report on Form 10-K, in
whole or in part, the foregoing Compensation Committee Report shall not be incorporated by reference into any such filings.

Pay Ratio Disclosure

As of the date of the filing of this Annual Report on Form 10-K, the pay ratio for Dr. Ji, our Chief Executive Officer, is not calculable. The pay ratio
is not calculable as the Compensation Committee has not, as of the date of the filing of this Annual Report on Form 10-K, yet determined the annual bonus
amounts, if any, that will be awarded our Chief Executive Officer for 2021. We expect the Compensation Committee to assess 2021 performance and
determine the 2021 annual bonus award and actual total compensation for our Chief Executive Officer in the second half of 2022. Once such annual bonus
amount, if any, has been determined, we will, in accordance with Securities and Exchange Commission rules and regulations, file a Current Report on Form
8-K or otherwise disclose the pay ratio within four business days after the Compensation Committee has assessed 2021 performance and determined the
2021 annual bonus awards and actual total compensation for our Chief Executive Officer.

Item 12. Security Ownership of Certain Beneficial Owners and Management and Related Stockholder Matters.

The following table sets forth information as of February 28, 2022, with respect to the beneficial ownership of shares of our common stock by:

•

each person or group known to us to be the beneficial owner of more than five percent of our common stock;

each of our directors;

each of our named executive officers; and

all of our current directors and executive officers as a group.

This table is based upon information supplied by officers, directors, and principal stockholders and a review of Schedules 13D and 13G, if any, filed
with the SEC. Other than as set forth below, we are not aware of any other beneficial owner of more than five percent of our common stock as of February
28, 2022. Except as indicated by the footnotes below, we believe, based on the information furnished to us, that the persons and entities named in the table
below have sole voting and investment power with respect to all shares of common stock that they beneficially own, subject to applicable community
property laws.

Applicable percentage ownership is based on 342,335,102 shares of common stock outstanding as of February 28, 2022, adjusted as required by
rules promulgated by the SEC. These rules generally attribute beneficial ownership of securities to persons who possess sole or shared voting power or
investment power with respect to those securities. In addition, the rules include shares of common stock issuable pursuant to the exercise of stock options
and warrants that are either immediately exercisable or exercisable on or before April 29, 2022, which is 60 days after February 28, 2022. These shares are
deemed to be outstanding and beneficially owned by the person holding those options for the purpose of computing the percentage ownership of that
person, but they are not treated as outstanding for the purpose of computing the percentage ownership of any other person.

Unless otherwise noted below, the address of each beneficial owner listed in the table is c/o Sorrento Therapeutics, Inc., 4955 Directors Place, San

Diego, California 92121.

Item 13. Certain Relationships and Related Transactions, and Director Independence.

Review, Approval or Ratification of Transactions with Related Persons

The Board conducts an appropriate review of and oversees all related party transactions on a continuing basis and reviews potential conflict of

interest situations where appropriate. The Board has not adopted formal standards to apply when it reviews, approves or ratifies any related party
transaction. However, the Board has followed the following standards: (i) all related party transactions must be fair and reasonable and on terms
comparable to those reasonably expected to be agreed to with independent third parties for the same goods and/or services at the time they are authorized
by the Board and (ii) all related party transactions should be authorized, approved or ratified by the affirmative vote of a majority of the directors who have
no interest, either directly or indirectly, in any such related party transaction.

Transactions with Related Persons

The following is a description of transactions or series of transactions since January 1, 2021, or any currently proposed transaction, to which we

have been a party, in which the amount involved in the transaction or series of transactions exceeds $120,000 and in which any of our directors, executive
officers or persons who we know held more than five percent of any class of our capital stock, including their immediate family members, had or will have
a direct or indirect material interest, other than compensation arrangements that are described under Item 11 of this Annual Report on Form 10-K.

Dr. Janda Consulting Agreement

manufacturer and supplier to Scilex Pharmaceuticals Inc. for ZTlido® (lidocaine topical system 1.8%). Effective January 19, 2021, ITOCHU CHEMICAL
FRONTIER Corporation no longer held any shares of outstanding capital stock of Scilex Holding Company. During the year ended December 31, 2021,
Scilex Pharmaceuticals Inc. purchased approximately $5.7 million of inventory from ITOCHU CHEMICAL FRONTIER Corporation.

Pulsar Therapeutics, Inc. License Agreement

On May 13, 2020, we entered into a license agreement with Pulsar Therapeutics, Inc. (“Pulsar”), pursuant to which we licensed Pulsar’s

nanoparticle technology for vaccine and antibody uses in exchange for a cash payment, certain royalties of net sales, a sublicense fee and an investment by
us in Pulsar through the transfer of 1.0 million shares of our common stock in exchange for a 5.0% equity interest in Pulsar. As of the date of the
investment, Henry Ji, Ph.D., a member of our Board and our Chief Executive Officer and President, was a director and chairperson of the board of directors
of Pulsar and owned approximately 45.0% of Pulsar’s outstanding shares, and Jaisim Shah, a member of our Board, owned approximately 5.0% of Pulsar’s
outstanding shares.

Cytimm Therapeutics, Inc. Equity Interest

On May 15, 2020, we acquired a 50% equity interest in Cytimm Therapeutics, Inc. (“Cytimm”) in exchange for an investment of $2.5 million by us.
As of the date of the acquisition, Henry Ji, Ph.D., a member of our Board and our Chief Executive Officer and President, was a director, the chairperson of
the board of directors and a stockholder of Cytimm.

Transactions with Deverra Therapeutics, Inc.

On December 7, 2021, we loaned Deverra Therapeutics, Inc. (“Deverra”) $1.0 million in consideration for the issuance of a promissory note by

Deverra to us. The note accrues interest at a rate of 10% per year and matures on the date that is six months from the date of issuance. As of the date of the
loan, Henry Ji, Ph.D., a member of our Board and our Chief Executive Officer and President, was a director and the chairperson of the board of directors of
Deverra, and Jaisim Shah, a member of our Board, was a director of Deverra.

Transactions with Aardvark Therapeutics, Inc.

In April 2021, we entered into an asset purchase agreement (the “Aardvark Asset Purchase Agreement”) with Aardvark Therapeutics, Inc. to acquire

Aardvark’s Delayed Burst Release Low Dose Naltrexone (DBR-LDN), or ARD-301, asset and intellectual property rights, for the treatment of chronic
pain, fibromyalgia and chronic post-COVID syndrome. As consideration for the purchase of the assets, we paid Aardvark an upfront license fee of $5.0
million comprised of 616,655 shares of our common stock. We also agreed to pay Aardvark (i) milestone payments upon the receipt of certain regulatory
approvals, and (ii) milestone payments upon our achievement of certain commercial sales milestones. We will also pay certain royalties in the mid-single
digit to low-double digit percentages of annual net sales by us. In May 2021, we paid $5.0 million in cash for 3,888,932 shares of Series B Preferred Stock
of Aardvark. In July 2021, we paid consideration of $5.0 million in cash for an additional 3,888,932 shares of Series B Preferred Stock of Aardvark,
resulting in an increase in our ownership interest in Aardvark to approximately 8%. Tien Lee, MD, a member of the board of directors of Scilex Holding
Company, our majority owned subsidiary, is the founder and chief executive officer of Aardvark. Kim D. Janda, Ph.D., a member of our Board, is a
member of the advisory board of Aardvark.

Indemnification Agreements with Directors and Executive Officers

We have entered into indemnity agreements with certain directors, officers and other key employees of ours under which we agreed to indemnify
those individuals under the circumstances and to the extent provided for in the agreements, for expenses, damages, judgments, fines, settlements and any
other amounts they may be required to pay in actions, suits or proceedings which they are or may be made a party or threatened to be made a party by
reason of their position as a director, officer or other agent of ours, and otherwise to the fullest extent permitted under Delaware law and our Bylaws. We
also have an insurance policy covering our directors and executive officers with respect to certain liabilities, including liabilities arising under the Securities
Act of 1933, as amended, or otherwise. We believe that these provisions and insurance coverage are necessary to attract and retain qualified directors,
officers and other key employees.

110

Board Independence

Our Board is responsible for establishing corporate policies and for our overall performance, although it is not involved in our day-to-day
operations. Our Board consults with our counsel to ensure that our Board’s determinations are consistent with all relevant securities and other laws and
regulations regarding the definition of “independent,” including those set forth in the rules of The Nasdaq Stock Market LLC, as in effect from time to
time. Consistent with these considerations, after review of all relevant transactions or relationships between each director, or any of his or her family
members, us, our senior management and our independent registered public accounting firm, our Board has determined that all of our directors, other than
Dr. Ji, Dr. Janda and Mr. Shah, are independent.

Item 14. Principal Accounting Fees and Services.

The following table represents aggregate fees billed to us for the fiscal years ended December 31, 2021 and December 31, 2020 by Ernst & Young

Audit fees consisted of fees for services rendered in connection with the annual audit of our consolidated financial statements, quarterly
reviews of financial statements included in our quarterly reports on Form 10-Q, and the audit of internal control over financial reporting.
Audit fees also consisted of services provided in connection with issuances of consents included in registration statements, standalone audits,
consultation on accounting matters, and SEC registration statement services.

Audit Committee’s Pre-Approval Policies and Procedures

The Audit Committee has adopted a policy for the pre-approval of audit and non-audit services rendered by our independent registered public
accounting firm. The policy generally pre-approves specified services in the defined categories of audit services, audit-related services and tax services up
to specified amounts. Pre-approval may also be given as part of the Audit Committee’s approval of the scope of the engagement of the independent auditors
or on an individual explicit case-by-case basis before the independent registered public accounting firm are engaged to provide each service. The pre-
approval of services may be delegated to one or more of the Audit Committee members, but the decision must be reported to the full Audit Committee at
its next scheduled meeting. By the adoption of this policy, the Audit Committee has delegated the authority to pre-approve services to the Chairperson of
the Audit Committee, subject to certain limitations.

The Audit Committee has determined that the rendering of services by Ernst & Young LLP other than audit services is compatible with maintaining

the principal accounting firm’s independence.

Report of Independent Registered Public Accounting Firm

To the Stockholders and the Board of Directors of Sorrento Therapeutics, Inc.

Opinion on Internal Control over Financial Reporting

We have audited Sorrento Therapeutics, Inc.’s internal control over financial reporting as of December 31, 2021, based on criteria established in Internal
Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO
criteria). In our opinion, because of the effect of the material weakness described below on the achievement of the objectives of the control criteria,
Sorrento Therapeutics, Inc. (the Company) has not maintained effective internal control over financial reporting as of December 31, 2021, based on the
COSO criteria.

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 the company’s annual or interim financial statements will not be prevented or detected on a timely basis. The following
material weakness has been identified and included in management’s assessment in the section, “Management’s Annual Report on Internal Control over
Financial Reporting”. Management has identified that the Company did not employ sufficient accounting resources with appropriate experience and
technical expertise to effectively execute controls over certain judgmental and technical accounting areas. As a result, certain of the Company’s control
activities in the areas of revenue, business combinations, investments, debt, derivative liabilities and leases did not operate effectively and have been
deemed deficient and the combination of the aforementioned deficiencies represents a material weakness in the Company’s internal control over financial
reporting.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated
balance sheets of the Company as of December 31, 2021 and 2020, the related consolidated statements of operations, comprehensive loss, stockholders’
equity and cash flows for the years then ended, and the related notes. This material weakness was considered in determining the nature, timing and extent
of audit tests applied in our audit of the 2021 consolidated financial statements, and this report does not affect our report dated March 11, 2022, which
expressed an unqualified opinion thereon that included an explanatory paragraph regarding the Company’s ability to continue as a going concern.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of
internal control over financial reporting included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our
responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm
registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the
applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether effective internal control over financial reporting was maintained in all material respects.

Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and
evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered
necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control Over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting
and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control
over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly
reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit
preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are
being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding
prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial
statements.

F-2

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of
effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of
compliance with the policies or procedures may deteriorate.

Report of Independent Registered Public Accounting Firm

To the Stockholders and the Board of Directors of Sorrento Therapeutics, Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Sorrento Therapeutics, Inc. (the Company) as of December 31, 2021 and 2020, the
related consolidated statements of operations, comprehensive loss, stockholders’ equity and cash flows for the years then ended, and the related notes
(collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material
respects, the financial position of the Company at December 31, 2021 and 2020, and the results of its operations and its cash flows for the years then ended,
in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s
internal control over financial reporting as of December 31, 2021, based on criteria established in Internal Control — Integrated Framework issued by the
Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) and our report dated March 11, 2022 expressed an adverse
opinion thereon.

The Company's Ability to Continue as a Going Concern

The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in
Note 2 to the consolidated financial statements, the Company has suffered recurring losses from operations, has recurring negative cash flows from
operations, and has stated that substantial doubt exists about the Company’s ability to continue as a going concern. Management's evaluation of the events
and conditions and management’s plans regarding these matters are also described in Note 2. The consolidated financial statements do not include any
adjustments that might result from the outcome of this uncertainty.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial
statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the
Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the
PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing
procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to
those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits
also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the
financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matters

The critical audit matters communicated below are matters arising from the current period audit of the financial statements that were communicated or
required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the financial statements and (2)
involved our especially challenging, subjective or complex judgments. The communication of critical audit matters does not alter in any way our opinion
on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions
on the critical audit matters or on the accounts or disclosures to which they relate.

Valuation of acquired intangible assets and contingent consideration liabilities recorded in connection with the ACEA Therapeutics, Inc. business
combination

F-3

Description of the
Matter

As disclosed in Note 7 of the consolidated financial statements, the Company completed the acquisition of ACEA
Therapeutics, Inc. (“ACEA”) on June 1, 2021 for net consideration of approximately $166.2 million. The transaction was
accounted for as a business combination. In connection with the acquisition, the Company recorded intangible assets
consisting of in-process research and development of $190.8 million. The Company recognized a liability of $122.1 million on
the acquisition date for consideration payable that is contingent upon achieving certain regulatory and sales-based milestones.
The Company determines the fair value of these contingent consideration arrangements, both as part of the initial purchase
price allocation and on an ongoing basis each reporting period, until the arrangements are settled. As of December 31, 2021,
the amount recorded for future estimated contingent consideration related to the ACEA acquisition is $131.3 million.

Auditing the Company’s accounting for its acquisition of ACEA was complex due to the significant estimation uncertainty in
determining the fair value of identified intangible assets and the recorded contingent consideration liabilities. The significant
estimation uncertainty was primarily due to the sensitivity of the respective fair values to underlying assumptions including
discount rates, revenue projections and estimated probabilities of successful commercialization. These significant assumptions
are forward-looking and could be affected by future economic and market conditions.

How We Addressed the
Matter in Our Audit

Our substantive audit procedures included, among others, involving our internal valuation specialists to assist us in evaluating
and testing the valuation methodologies and significant assumptions stated above. For example, we compared the significant
assumptions to current industry, market and economic trends, to historical results of the Company's business and other
guideline companies in the same industry and to other sources. Furthermore, we performed, among other procedures,
independent comparative calculations to estimate certain significant assumptions and compared our estimates with those of the
Company. We also performed a sensitivity analysis of the significant assumptions to evaluate the change in the fair value of
the acquired in-process research and development assets and contingent consideration liabilities recorded that would result
from changes in the assumptions.

Scilex notes and valuation of embedded derivative liabilities

Description of the
Matter

The carrying value of the Company’s Scilex notes was $101.2 million as of December 31, 2021. As discussed in Note 1 to the
consolidated financial statements, the Company accounts for debt, such as the Scilex notes, as liabilities measured at amortized
cost and amortizes the resulting debt discount from the allocation of proceeds, to interest expense using the effective interest
method over the expected term of the debt instrument. The Company’s derivative liabilities were valued at $35.7 million as of
December 31, 2021. The derivative liabilities consist of various embedded features in the Scilex notes. As discussed in Note 3
to the consolidated financial statements, the fair value of the embedded derivative liabilities was estimated using the
discounted cash flow method under the income approach, combined with a Monte Carlo simulation model.

Auditing the carrying value of the Scilex notes was challenging because of the subjective auditor judgment necessary in
evaluating the propriety of the Company’s accounting for certain embedded features within the Scilex notes that are not
derivative liabilities. Such embedded features include contractual increases in outstanding principal, contingent on the
achievement of certain predetermined target sales thresholds over certain periods. Auditing the Company’s valuation of its
embedded derivative liabilities was challenging because of the subjective auditor judgment necessary in evaluating the
propriety of the complex valuation methodologies and significant assumptions used in estimating the fair value of such
embedded derivative liabilities as of the balance sheet date. Such significant assumptions include a risk adjusted net sales
forecast and an effective debt yield.

How We Addressed the
Matter in Our Audit

Our substantive audit procedures included, among others, assessing the impact on the carrying value of embedded features
within the Scilex notes that are not derivative liabilities and independently recalculating the carrying value of the Scilex notes
in accordance with the terms of the arrangement. As it relates to the embedded derivative liabilities, we involved our internal
valuation specialists to assist us in evaluating and testing the valuation methodologies and significant assumptions stated
above. For example, we performed independent comparative calculations to estimate a risk adjusted net sales forecast and
effective debt yield and compared our estimates with the Company’s assumptions. Additionally, we searched for contrary
evidence, including, for example, comparing the Company’s revenue projections within the valuation models to the historical
financial results of the Company.

year ended December 31, 2019, in conformity with accounting principles generally accepted in the United States of America.

Going Concern

The accompanying financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 2 to the
financial statements, the Company’s negative working capital, recurring losses from operations, recurring negative cash flows from operations and
substantial cumulative net losses raise substantial doubt about its ability to continue as a going concern. Management's plans in regard to these matters are
also described in Note 2. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company’s financial
statements based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company
in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audit included performing procedures
to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks.
Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audit also included
evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial
statements. We believe that our audit provides a reasonable basis for our opinion.

SORRENTO THERAPEUTICS, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Organization and Significant Accounting Policies

Description of Business

Sorrento Therapeutics, Inc. (the “Company”) is a clinical and commercial stage biopharmaceutical company developing new therapies to treat
cancer, pain (non-opioid treatments), autoimmune disease and COVID-19. The Company’s multimodal, multipronged approach to fighting cancer is made
possible by its extensive immuno-oncology platforms, including key assets such as fully human antibodies (“G-MAB™ library”), immuno-cellular
therapies (“DAR-T™”), antibody-drug conjugates (“ADCs”), and oncolytic virus (“Seprehvec™”). The Company is also developing potential antiviral
therapies and vaccines against coronaviruses, including Abivertinib, COVI-AMG™, COVISHIELD™, COVI-MSC™ and COVIDROPS™; and diagnostic
test solutions, including COVITRACK™ and COVISTIX™.

The Company’s commitment to life-enhancing therapies for patients is also demonstrated by its effort to advance a first-in-class (TRPV1 agonist)

non-opioid pain management small molecule, resiniferatoxin (“RTX”), and SP-102 (10 mg, dexamethasone sodium phosphate viscous gel)
(SEMDEXA™), a novel, viscous gel formulation of a widely used corticosteroid for epidural injections to treat lumbosacral radicular pain, or sciatica, and
to commercialize ZTlido® (lidocaine topical system) 1.8% for the treatment of post-herpetic neuralgia (PHN). RTX has been cleared for a Phase II trial for
intractable pain associated with cancer and a Phase II trial in osteoarthritis patients. SEMDEXA announced highly statistically significant positive top-line
results from its Phase III Pivotal Trial C.L.E.A.R Program for its novel, non-opioid product for the treatment of lumbosacral radicular pain (sciatica).
ZTlido® was approved by the FDA on February 28, 2018.

Basis of Presentation and Principles of Consolidation

The accompanying consolidated financial statements include the accounts of the Company`s subsidiaries. For consolidated entities where the

Company owns or is exposed to less than 100% of the economics, the Company records net income (loss) attributable to noncontrolling interests in its
consolidated statements of operations equal to the percentage of the economic or ownership interest retained in such entities by the respective
noncontrolling parties. All intercompany balances and transactions have been eliminated in consolidation. The Company operates in two operating and
reportable segments, Sorrento Therapeutics and Scilex. The Sorrento Therapeutics segment is organized around the Company’s immuno-oncology
therapeutic area, leveraging its proprietary G-MAB™ antibody library and targeted delivery modalities to generate the next generation of cancer
therapeutics. The Scilex segment is largely organized around the Company’s non-opioid pain management operations. See Note 14.

Use of Estimates

The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America

(“U.S. GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the reporting period. Management believes that these estimates are reasonable;
however, actual results may differ from these estimates.

Cash and Cash Equivalents

The Company considers all highly liquid investments purchased with original maturities of three months or less to be cash equivalents. Cash and

cash equivalents consist of money market accounts and bank deposits, which are highly liquid and readily tradable.

Fair Value of Financial Instruments

The Company follows accounting guidance on fair value measurements for financial instruments measured on a recurring basis, as well as for
certain assets and liabilities that are initially recorded at their estimated fair values. Fair value is defined as the exit price, or the amount that would be
received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The Company
uses the following three-level hierarchy that maximizes the use of observable inputs and minimizes the use of unobservable inputs to value its financial
instruments:

•

Level 1: Observable inputs such as unadjusted quoted prices in active markets for identical instruments.

Level 2: Quoted prices for similar instruments that are directly or indirectly observable in the marketplace.

F-12

•

Level 3: Significant unobservable inputs which are supported by little or no market activity and that are financial instruments whose values
are determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which the
determination of fair value requires significant judgment or estimation.

Financial instruments measured at fair value are classified in their entirety based on the lowest level of input that is significant to the fair value

measurement. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires it to make
judgments and consider factors specific to the asset or liability. The use of different assumptions and/or estimation methodologies may have a material
effect on estimated fair values. Accordingly, the fair value estimates disclosed or initial amounts recorded may not be indicative of the amount that the
Company or holders of the instruments could realize in a current market exchange.

The carrying amounts of cash equivalents approximate their fair value based upon quoted market prices. Certain of the Company’s financial

instruments are not measured at fair value on a recurring basis, but are recorded at amounts that approximate their fair value due to their liquid or short-
term nature, such as accounts receivable and payable, and other financial instruments in current assets or current liabilities.

Accounts Receivable, Net

Accounts receivable are presented net of allowances for expected credit losses and consist of trade receivables from sales and services provided to

certain customers, which are generally unsecured. The Company reviews reserves and makes adjustments based on historical experience and known
collectability issues and disputes. When internal collection efforts on accounts have been exhausted, the accounts are written off by reducing the allowance
for doubtful accounts. The allowance for doubtful accounts is not material.

Inventory

The Company determines inventory cost on a first-in, first-out basis. The Company reduces the carrying value of inventories to a lower of cost or
net realizable value for those items that are potentially excess, obsolete or slow-moving. The Company considers the need for allowances for excess and
obsolete inventory based upon historical experience, sales trends, and specific categories of inventory and expiration dates for inventory on hand. As of
December 31, 2021, net inventory was $8.1 million, comprised of $4.7 million of finished goods and $3.3 million of raw materials and supplies. Net
inventory as of December 31, 2020 was $1.8 million, primarily comprised of finished goods.

Property and Equipment

Property and equipment are carried at cost less accumulated depreciation. Depreciation of property and equipment is computed using the straight-

line method over the estimated useful lives of the assets, which are generally three to five years. Leasehold improvements are amortized over the lesser of
the life of the lease or the life of the asset. Repairs and maintenance are charged to expense as incurred.

Acquisitions

The Company accounts for business combinations using the acquisition method of accounting, which requires that assets acquired, including in-

process research and development (“IPR&D”) projects and liabilities assumed be recorded at their fair values as of the acquisition date on the Company`s
consolidated balance sheets. Any excess of purchase price over the fair value of net assets acquired is recorded as goodwill. The determination of estimated
fair value requires the Company to make significant estimates and assumptions. As a result, the Company may record adjustments to the fair values of
assets acquired and liabilities assumed within the measurement period (up to one year from the acquisition date) with the corresponding offset to goodwill.
Transaction costs associated with business combinations are expensed as they are incurred.

When the Company determines net assets acquired do not meet the definition of a business combination under the acquisition method of accounting,

the transaction is accounted for as an acquisition of assets and, therefore, no goodwill is recorded and contingent consideration such as payments upon
achievement of various developmental, regulatory and commercial milestones generally is not recognized at the acquisition date. In an asset acquisition,
up-front payments allocated to IPR&D projects at the acquisition date and subsequent milestone payments are charged to expense in the Company`s
consolidated statements of operations unless there is an alternative future use.

Contingent Consideration

F-13

The fair value of contingent consideration liabilities assumed in business combinations is recorded as part of the purchase price consideration of the

acquisition, and is determined using a discounted cash flow model or Monte Carlo simulation model. The significant inputs of such models are not
observable in the market, such as certain financial metric growth rates, volatility rates, projections associated with applicable milestones, discount rates and
the related probabilities and payment structure in the contingent consideration arrangement. Fair value adjustments to contingent consideration liabilities
are recorded through operating expenses in the consolidated statement of operations. Contingent consideration arrangements assumed in an asset
acquisition will be measured and accrued when such contingency is resolved.

Acquired In-Process Research and Development

The Company has acquired, and may continue to acquire, the rights to develop and commercialize new drug candidates. The up-front payments to

acquire new drug compounds or drug delivery devices, as well as future milestone payments associated with assets that do not meet the definition of a
derivative and that are deemed probable to achieve, are immediately expensed as acquired IPR&D, provided that the drug candidates have not achieved
regulatory approval for marketing and, absent obtaining such approval, have no alternative future use. Intangible assets acquired in a business combination
that are used for IPR&D activities are considered indefinite lived until the completion or abandonment of the associated research and development efforts.
Upon commercialization of the relevant research and development project, the Company amortizes the acquired IPR&D over its estimated useful life.
Capitalized IPR&D is reviewed annually for impairment or more frequently as changes in circumstance or the occurrence of events suggest that the
remaining value may not be recoverable.

Goodwill and Other Long-Lived Assets

Goodwill, which has an indefinite useful life, represents the excess of cost over fair value of net assets acquired. Goodwill is reviewed at the
reporting unit level for impairment at least annually during the fourth quarter, or more frequently if events occur indicating the potential for impairment.
During its goodwill impairment review, the Company assesses qualitative factors to determine whether it is more likely than not that the fair value of its
reporting unit is less than its carrying amount, including goodwill. The qualitative factors include, but are not limited to, macroeconomic conditions,
industry and market considerations, and the overall financial performance of the Company. If, after assessing the totality of these qualitative factors, the
Company determines that it is not more likely than not that the fair value of its reporting unit is less than its carrying amount, then no additional assessment
is deemed necessary. Otherwise, the Company performs a quantitative goodwill impairment test. The Company may also elect to bypass the qualitative
assessment in a period and elect to proceed to perform the quantitative goodwill impairment test. The Company performed its annual assessment for
goodwill impairment at the Sorrento Therapeutics and Scilex reporting unit levels in the fourth quarter of 2021, noting no indication of impairment. There
were no triggering events indicating the potential for impairment through December 31, 2021.

The Company evaluates its long-lived and intangible assets with definite lives, such as property and equipment, acquired technology, customer

relationships, patent and license rights, for impairment by considering the expected use of the assets and the effects of obsolescence, demand, anticipated
technological advances, market influences and other economic factors. The factors that drive the estimate of useful life are often uncertain and are reviewed
on a periodic basis or when events occur that warrant review. Recoverability is measured by comparison of the assets’ net book value to future net
undiscounted cash flows that the assets are expected to generate.

Debt, Including Debt With Detachable Warrants

Detachable warrants are evaluated for the classification of warrants as either equity instruments, derivative liabilities, or liabilities depending on the
specific terms of the warrant agreement. In circumstances in which debt is issued with equity-classified warrants, the proceeds from the issuance of debt are
first allocated to the debt and the warrants at their relative estimated fair values. The portion of the proceeds allocated to the warrants are accounted for as
paid-in capital and a debt discount. The remaining proceeds, as further reduced by discounts created by the bifurcation of embedded derivatives and
beneficial conversion features, are allocated to the debt. The Company accounts for debt as liabilities measured at amortized cost and amortizes the
resulting debt discount from the allocation of proceeds, to interest expense using the effective interest method over the expected term of the debt
instrument. The Company considers whether there are any embedded features in debt instruments that require bifurcation and separate accounting as
derivative financial instruments pursuant to Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 815,
Derivatives and Hedging.

If the amount allocated to the convertible debt results in an effective per share conversion price less than the fair value of the Company’s common

stock on the commitment date, the intrinsic value of this beneficial conversion feature is recorded as a discount to the convertible debt with a corresponding
increase to additional paid in capital. The beneficial conversion feature discount is equal

F-14

to the difference between the effective conversion price and the fair value of the Company’s common stock at the commitment date, unless limited by the
remaining proceeds allocated to the debt.

The Company may enter financing arrangements, the terms of which involve significant assumptions and estimates, including future net product
sales, in determining interest expense, amortization period of the debt discount, as well as the classification between current and long-term portions. In
estimating future net product sales, the Company assesses prevailing market conditions using various external market data against the Company’s
anticipated sales and planned commercial activities. Consequently, the Company imputes interest on the carrying value of the debt and records interest
expense using an imputed effective interest rate. The Company reassesses the expected payments each reporting period and accounts for any changes
through an adjustment to the effective interest rate on a prospective basis, with a corresponding impact to the classification of the Company’s current and
long-term portions.

Derivative Liabilities

Derivative liabilities are recorded on the Company`s consolidated balance sheets at their fair value on the date of issuance and are revalued on each

balance sheet date until such instruments are settled or expire, with changes in the fair value between reporting periods recorded as other income or
expense.

Investments in Other Entities

The Company holds a portfolio of investments in equity securities. Investments in entities over which the Company has significant influence, but

not a controlling interest, are accounted for using the equity method, with the Company’s share of earnings or losses reported in loss on equity method
investments. The Company’s other equity investments non-marketable securities are carried at cost, less impairment, plus or minus changes resulting from
observable price changes in orderly transactions for identical or similar investments. The Company’s investments in marketable equity securities are
measured at fair value.

Research and Development Costs

The Company expenses the cost of research and development as incurred. Research and development expenses are comprised of costs incurred in

performing research and development activities, including clinical trial costs, manufacturing costs for both clinical and preclinical materials as well as other
contracted services, license fees and other external costs. Nonrefundable advance payments for goods and services that will be used in future research and
development activities are expensed when the activity is performed or when the goods have been received, rather than when payment is made, in
accordance with FASB ASC Topic 730, Research and Development.

Income Taxes

The provisions of the FASB ASC Topic 740 “Income Taxes,” addresses the determination of whether tax benefits claimed or expected to be claimed
on a tax return should be recorded in the financial statements. Under ASC Topic 740-10, the Company may recognize the tax benefit from an uncertain tax
position only if it is more likely than not that the tax position will be sustained on examination by taxing authorities, based on the technical merits of the
position. The Company has determined that it has uncertain tax positions.

The Company accounts for income taxes using the asset and liability method to compute the differences between the tax basis of assets and

liabilities and the related financial amounts, using currently enacted tax rates.

The Company has deferred tax assets, which are subject to periodic recoverability assessments. Valuation allowances are established, when
necessary, to reduce deferred tax assets to the amount that more likely than not will be realized. As of December 31, 2021, the Company maintained a full
valuation allowance against its deferred tax assets, with the exception of an amount equal to its deferred tax liabilities that are scheduled to reverse against
the Company's deferred tax assets.

Leases

The Company determines if an arrangement is a lease at inception. Operating lease right-of-use (“ROU”) assets and lease liabilities are recognized

at the commencement date based on the present value of lease payments over the lease term. As the Company`s leases do not provide an implicit rate, it
uses its incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments. The
Company calculates the associated lease liability and corresponding ROU asset upon lease commencement using a discount rate based on a credit-adjusted
secured borrowing rate commensurate with the term of the lease. The operating lease ROU asset also includes any lease payments made and is reduced by

F-15

lease incentives. The Company’s lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will
exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term.

Revenue Recognition

The Company`s revenues are generated from product sales, the sale of customized reagents and other materials, contract manufacturing services,

and other service revenues.

The following table shows revenue disaggregated by product and service type for the years ended December 31, 2021, 2020 and 2019 (in

The Company is obligated to accept from customers the return of products sold that are damaged or do not meet certain specifications. The
Company may authorize the return of products sold in accordance with the terms of its sales contracts and estimates allowances for such amounts at the
time of sale.

The Company does not disclose the value of unsatisfied performance obligations for (i) contracts with an original expected length of one year or less

and (ii) contracts for which it recognizes revenue at the amount to which it has the right to invoice for services performed.

Scilex Product Sales

Revenues from product sales is fully comprised of sales of ZTlido. The Company's performance obligation with respect to sales of ZTlido is

satisfied at a point in time, which transfers control upon delivery of product to the customer. The Company considers control to have transferred upon
delivery because the customer has legal title to the asset, physical possession of the asset has been transferred to the customer, the customer has significant
risks and rewards of ownership of the asset, and the Company has a present right to payment at that time. The Company identified a single performance
obligation. Invoicing typically occurs upon shipment and the length of time between invoicing and when payment is due is not significant. The aggregate
dollar value of unfulfilled orders as of December 31, 2021 was not material. Sales of ZTlido are generated within the United States. Substantially all of the
Company’s product revenue and accounts receivable result from a sole customer.

For product sales, the Company records gross-to-net sales adjustments for government and managed care rebates, chargebacks, wholesaler and
distributor fees, sales returns and prompt payment discounts. Such variable consideration is estimated in the period of the sale and is estimated using a most
likely amount approach based primarily upon provisions included in the Company’s customer contract, customary industry practices and current
government regulations.

Concortis Biosystems Corporation (“Concortis”)

Contract manufacturing revenue associated with sales of customized reagents related to delivering proprietary cytotoxins, linkers and linker-toxins is

recognized at a point in time upon the transfer of control, which is generally upon shipment given the short contract terms of two months or less generally.
Revenue associated with contract development and manufacturing of highly customized ADC services related to providing synthetic expertise to antibodies
provided by customers is recognized over time as the service and related deliverables are highly customized and unique to each customer’s needs, which
does not have alternative use to the Company. The Company also has an enforceable right to the payment for the ADC services completed to date. In
recognizing the revenue over time, the Company measures its progress using an input method based on the effort it expends toward the satisfaction of its
performance obligations. The Company estimates the amount of effort it expends including the time it will take the Company to complete the activities
relative to the estimated total effort to satisfy each performance obligation. This approach requires the Company to make estimates and use judgement. If
the Company’s estimates or judgements change over the course of the contract, they may affect the timing and amount of revenue that the Company
recognizes in the current and future periods.

F-16

As of December 31, 2021, the estimated revenue expected to be recognized for future performance obligations associated with contract development

and manufacturing services was approximately $0.2 million.

Bioserv Corporation (“Bioserv”)

Contract manufacturing services associated with the Company’s Bioserv operations related to finish and fill activities for drug products and reagents

are recognized ratably over the contract term, which reflects the transfer of services to the customer because the manufactured products are highly
customized and do not have an alternative use to the Company.

As of December 31, 2021 and 2020, the estimated revenue expected to be recognized for future performance obligations associated with contract

manufacturing services was approximately $0.1 million and $3.4 million, respectively.

Other Service Revenue

If the license to the Company’s intellectual property is determined to be distinct from the other performance obligations identified in the

arrangement, the Company recognizes revenue from non-refundable, up-front fees allocated to the license when the license is transferred to the customer
and the customer is able to use and benefit from the license. If the license to the Company’s intellectual property is bundled with other promises that are not
distinct, the Company assesses the nature of the combined performance obligation to determine whether it is satisfied over time or at a point in time and, if
over time, the appropriate method of measuring progress for purposes of recognizing revenue from non-refundable, up-front fees. The Company recorded
the non-refundable, up-front license fee under current license agreements as deferred revenue upon receipt of the payment as it is determined not distinct
from the ongoing performance obligation. License revenue is recognized over the term when the ongoing performance obligation is satisfied.

As of December 31, 2021, future performance obligations for license revenues relate to the ImmuneOncia Therapeutics, LLC (“ImmuneOncia”) and

NantCell, Inc. (“NantCell”) license agreements.

The total consideration for the ImmuneOncia license performance obligation, effective September 1, 2016, represented $9.6 million. The estimated
revenue expected to be recognized for future performance obligations, as of December 31, 2021, was approximately $7.0 million. The Company expects to
recognize license revenue of approximately $0.5 million of the remaining performance obligation annually through the remaining term. The Company
applied judgment in estimating the 20-year contract term, analogous to the expected life of the patent, over which revenue is recognized over time given the
ongoing performance obligation related to the Company's participation on a steering committee for the technologies under the agreement.

As of December 31, 2021 and 2020, the NantCell license agreement, effective April 21, 2015, represented $110.0 million of contract liabilities

reflected in long-term deferred revenue. See Note 7 for additional information regarding the remaining performance obligation for the agreement.

In November 2020, the Company was awarded a contract with the Defense Advanced Research Projects Agency (“DARPA Contract”) and co-
funded by the Joint Program Executive Office for Chemical, Biological, Radiological and Nuclear Defense, to develop a rapid countermeasure to COVID-
19 using gene-encoded neutralizing antibodies. The contract provides funding of up to $34.0 million for the development through Phase II clinical studies
of a gene-encoded antibody that could enable rapid protection from and/or treatment of SARS-CoV-2 infection and COVID-19. The Company recognized
$2.8 million and $0.2 million in grant revenue associated with the DARPA Contract during the years ended December 31, 2021 and 2020, respectively,
which is included within other service revenue.

F-17

Stock-Based Compensation

The Company estimates the fair value of stock option awards and its Employee Stock Purchase Plan (“ESPP”) on the grant or offering date using the
Black-Scholes option-pricing model. The Black-Scholes option-pricing model requires inputs such as the risk-free interest rate, expected term and expected
volatility. Stock-based compensation expense is recognized on a straight-line basis, net of actual forfeitures in the period. The Company estimated the CEO
Performance Award (as defined in Note 10) on the grant date using Monte Carlo simulations. Key assumptions for estimating the performance-based
awards fair value at the date of grant included, volatility of the Company’s common stock price, post-vesting exercise behavior, and the derived service
period. Recognition of stock-based compensation expense of all the tranches commenced on the date of grant, as the probability of meeting the ten market
capitalization milestones is not considered in determining the timing of expense recognition. The expense will be recognized ratably over the expected
vesting period of each respective tranche.

Comprehensive Loss

Comprehensive loss is primarily comprised of net income (loss) and foreign currency translation adjustments. The Company displays

comprehensive loss and its components in its consolidated statements of comprehensive loss.

Net Loss per Share

Basic net loss per share is computed by dividing net loss for the period by the weighted average number of shares of common stock outstanding.

Diluted net loss per share reflects the additional dilution from potential issuances of common stock, such as stock issuable pursuant to the exercise of stock
options or the exercise of outstanding warrants. The treasury stock method and the if-converted method are used to calculate the potential dilutive effect of
these common stock equivalents. Potentially dilutive shares are excluded from the computation of diluted net loss per share when their effect is anti-
dilutive. In periods where a net loss is presented, all potentially dilutive securities are anti-dilutive and are excluded from the computation of diluted net
loss per share.

Recent Accounting Pronouncements

In October 2021, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2021-08, Business

Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers, which requires an acquirer in a
business combination to recognize and measure contract assets and contract liabilities in accordance with Accounting Standards Codification (“ASC”)
Topic 606. ASU 2021-08 is effective for fiscal years beginning after December 15, 2022 and early adoption is permitted. The Company is evaluating the
impact the standard will have on its consolidated financial statements.

In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. The amendments
in this update simplify the accounting for income taxes by removing certain exceptions to the general principles in ASC Topic 740. The amendments also
improve consistent application of and simplify U.S. GAAP for other areas of ASC Topic 740 by clarifying and amending existing guidance. The
amendments in this update are effective for interim and annual periods for the Company beginning after December 15, 2020. The Company adopted the
standard on January 1, 2021. The adoption of the standard had no impact on its consolidated financial statements.

2. Liquidity and Going Concern

The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern, which
contemplates the realization of assets and satisfaction of liabilities in the normal course of business. The Company has negative working capital and
recurring losses from operations, recurring negative cash flows from operations and substantial cumulative net losses to date and anticipates that it will
continue to do so for the foreseeable future as it continues to identify and invest in advancing product candidates, as well as expanding corporate
infrastructure.

The Company has plans in place to obtain sufficient additional fundraising to fulfill its operating and capital requirements for the next 12 months.

The Company’s plans include continuing to fund its operating losses and capital funding needs through public or private equity or debt financings, strategic
collaborations, licensing arrangements, asset sales, government grants or other arrangements. Although management believes such plans, if executed,
should provide the Company sufficient financing to meet its needs, successful completion of such plans is dependent on factors outside of the Company’s
control. As such, management cannot conclude that such plans will be effectively implemented within one year after the date that the financial statements
are issued. As a result, management has concluded that the aforementioned conditions, among others, raise substantial doubt about the Company’s ability to
continue as a going concern within one year after the date the financial statements are issued.

If the Company is unable to raise additional capital in sufficient amounts or on terms acceptable, the Company may have to significantly delay, scale

back or discontinue the development or commercialization of one or more of its product candidates. The

F-18

Company may also seek collaborators for one or more of its current or future product candidates at an earlier stage than otherwise would be desirable or on
terms that are less favorable than might otherwise be available. The consolidated financial statements do not reflect any adjustments that might be
necessary if the Company is unable to continue as a going concern.

If the Company raises additional funds by issuing equity securities, substantial dilution to existing stockholders would result. If the Company raises

additional funds by incurring debt financing, the terms of the debt may involve significant cash payment obligations as well as covenants and specific
financial ratios that may restrict the Company’s ability to operate its business.

As further discussed in Note 5, the Company holds 20,422,124 shares of Celularity Inc. (“Celularity”) Class A Common Stock of which 19,922,124
shares with a value of approximately $87.7 million as of December 31, 2021 are subject to certain transfer restrictions. The shares held by the Company are
measured at fair value at each reporting period based on the closing price of Celularity’s common stock on the last trading day of each reporting period, and
the shares subject to transfer restriction are adjusted for a discount for lack of marketability. As of December 31, 2021, the discount for lack of
marketability was determined using a Monte Carlo simulation model resulting in an implied discount for lack of marketability of 14.0%.

Contingent Consideration

In connection with the acquisition of ACEA Therapeutics, Inc. (“ACEA”) as further discussed in Note 7, the Company preliminarily recorded

estimated contingent consideration of $122.1 million as of the acquisition date of June 1, 2021. The Company

F-19

assessed the fair value of contingent consideration using a discounted cash flow method combined with a Monte Carlo simulation model. Significant Level
3 assumptions used in the measurement include revenue projections, estimated probabilities of successful commercialization and a discount rate of 14.4%
and 15.0% as of June 1, 2021 and December 31, 2021, respectively. As further discussed in Note 7, the Indebtedness Shares (as defined in Note 7) were
subject to a true-up, as set forth in the ACEA Merger Agreement (as defined in Note 7), if the price at which such shares were issued was greater than the
closing price of the Company’s common stock on the date that was six months after June 1, 2021 (“Put Option”). The Company assessed the fair value of
the Put Option using a Black-Scholes model and Level 3 assumptions. The Company recorded a total fair value of $8.9 million and $7.5 million associated
with the Put Option as of June 1, 2021 and December 31, 2021, respectively. The Put Option is included within the current portion of the contingent
consideration and acquisition consideration payable. During the year ended December 31, 2021, the Company recorded a loss of $9.2 million related to the
change in fair value of the contingent consideration.

There were no changes to the fair value of contingent consideration during the year ended December 31, 2020.

During the year ended December 31, 2019, the fair value remeasurement adjustments related to the Company’s acquisitions resulted in a decrease to

the contingent consideration liabilities by $0.7 million. The Company also recorded a $10.4 million gain related to the settlement of the acquisition
consideration payable associated with the acquisition of Virttu Biologics Limited in 2017.

Derivative liabilities

The Company recorded a loss on derivative liabilities of $0.3 million during the year ended December 31, 2021, which related to the compound
derivative liabilities associated with the Scilex Notes (as defined in Note 8). The Company recorded a gain on derivative liabilities of $6.6 million and a
loss on derivative liabilities of $36.8 million for the years ended December 31, 2020 and 2019, respectively, which related to the compound derivative
liabilities associated with the Term Loans (as defined in Note 8) and the Scilex Notes. The compound derivative liabilities consist of the fair value of
various embedded features as further described in Note 8. The fair value of the derivative liabilities associated with the Scilex Notes was estimated using
the discounted cash flow method under the income approach combined with a Monte Carlo simulation model. This involves significant Level 3 inputs and
assumptions.

The key assumptions for the Scilex Notes for the year ended December 31, 2021 included a 6.2% risk-adjusted net sales forecast and an effective
debt yield of 15.0%. The key assumptions for the Scilex Notes for the year ended December 31, 2020 included a 7% risk-adjusted net sales forecast, an
effective debt yield of 15% and an estimated probability of 100% of not obtaining marketing approval before March 31, 2021. The key assumptions for the
Scilex Notes for the year ended December 31, 2019 included an 8% risk adjusted net sales forecast, an effective debt yield of 19.7% and estimated
probabilities of 55% and 100% of not obtaining marketing approval before July 1, 2023 and March 31, 2021, respectively, and an estimated high
probability of a Scilex Holding IPO that satisfies certain valuation thresholds.

As further discussed in Note 8, the Term Loans, which include the Early Conditional Loan, were paid in full as of December 31, 2020 and the
associated derivative liabilities were relieved. Significant Level 3 inputs and assumptions for derivative liabilities associated with the Term Loans primarily
included the estimated probabilities of satisfying certain commercial and financial milestones estimated using a with and without discounted cash flow
approach.

During the year ended December 31, 2019, the Company recorded a derivative liability and corresponding debt discount of approximately $7.0

million, which was attributed to a contingent acceleration feature related to the Early Conditional Loan. The debt discount was amortized over the
remaining term of the Term Loans and was recorded as interest expense in the consolidated statement

F-20

of operations. Additionally, the Company recorded a mark-to-market loss on derivative liabilities related to the contingent acceleration feature of the Early
Conditional Loan of $1.8 million for the year ended December 31, 2019. The Company also recorded a loss on derivative liabilities of $4.3 million during
2019 associated with the 2019 Warrants (as defined in Note 8) for the year ended December 31, 2019.

5. Investments

The Company’s investments include investments accounted for as equity method investments, equity investments without readily determinable fair

value and equity investments with readily determinable fair value. As of December 31, 2021, the Company’s equity method investments include an
ownership interest in Immunotherapy NANTibody, LLC (“NANTibody”), NantCancerStemCell, LLC (“NantStem”), Deverra Therapeutics, Inc.
(“Deverra”) and ImmuneOncia Therapeutics, LLC, among others. The Company’s equity investments without readily determinable fair value include an
ownership interest in NantBioScience, Inc. (“NantBioScience”), Aardvark Therapeutics, Inc. (“Aardvark”) and Elsie Biotechnologies, Inc. (“Elsie”),
among others. The Company’s equity investments with readily determinable fair value include an ownership interest in Celularity.

The Company recorded no impairment loss for the year ended December 31, 2021. During the year ended December 31, 2020, the Company

value is no longer supportable. The loss is included within loss on equity method investments in the Company’s consolidated statement of operations.

Celularity

On July 16, 2021, Celularity (“Pre-Merger Celularity”), a company of which the Company held an equity interest, completed its previously
announced merger with GX Acquisition Corp. (the “Celularity Merger”). Following the completion of the Celularity Merger, the combined, publicly traded
company formerly known as GX Acquisition Corp. was renamed Celularity Inc. and its Class

F-21

A common stock commenced trading on the Nasdaq Capital Market on July 19, 2021 under the ticker “CELU”. In connection with the Celularity Merger,
all outstanding shares of Series A Preferred Stock of Pre-Merger Celularity were converted into shares of Pre-Merger Celularity common stock and then
each share of Pre-Merger Celularity common stock was converted into the right to receive shares of Class A common stock of the post-merger company.
The Company received 19,922,124 shares of Class A common stock of the post-merger company in the Celularity Merger. The Company also purchased an
aggregate of 500,000 shares of Class A common stock of Celularity for an aggregate purchase price of $5,000,000 in a private placement transaction that
closed on July 16, 2021 concurrently with the closing of the Celularity Merger (the “Private Placement Shares”). Dr. Henry Ji, the Company’s Chief
Executive Officer and Chairperson, and Jaisim Shah, a member of the Company’s Board of Directors, each served on the board of directors of Pre-Merger
Celularity from June 2017 until the closing of the Celularity Merger in July 2021. Dr. Robin L. Smith, who served as a member of the Company’s Board of
Directors from December 2019 through November 15, 2021, served on the board of directors of Pre-Merger Celularity from August 2019 until the closing
of the Celularity Merger in July 2021 and has served on the board of directors of Celularity since the closing of the Celularity Merger in July 2021.

The Company’s investment in Celularity has historically been included as an equity investment in its consolidated balance sheets and accounted for
as an equity security without a readily determinable fair value of $125.0 million before the trading commencement date. As of the trading commencement
date, the Company accounts for its investment in Celularity as an equity security with a readily determinable fair value. As of December 31, 2021, the
Company owned 20,422,124 shares of Class A common stock of Celularity. 19,922,124 shares of the Class A Common Stock of Celularity held by the
Company are subject to transfer restrictions until the earliest to occur of (i) 365 days after July 16, 2021; (ii) the first day after the date on which the closing
price of the Class A Common Stock equals or exceeds $12.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and
the like) for any 20 trading days within any 30-trading day period commencing at least 150 days after July 16, 2021; or (iii) the date on which Celularity
completes a liquidation, merger, capital stock exchange, reorganization or other similar transaction that results in all of Celularity’s public shareholders
having the right to exchange their Class A Common Stock for cash, securities or other property, subject to certain exceptions (the “Restricted Shares”).

In connection with the change in fair value of the Restricted Shares, the Company recorded an unrealized loss on equity investment of $37.3 million

during the year ended December 31, 2021. The Company has reclassified its investment in Celularity associated with the Restricted Shares to marketable
investments under current assets within its consolidated balance sheets. The investment in Celularity associated with the Restricted Shares is classified as a
current asset because the investment can be liquidated to finance the Company’s current operations once the transfer restrictions are lifted, which will occur
before December 31, 2022. In connection with the change in fair value of the Private Placement Shares, the Company recorded an unrealized loss of $2.4
million on marketable investments during the year ended December 31, 2021. The Company classifies its investment in Celularity associated with the
Private Placement Shares as marketable investments within its consolidated balance sheets. The investment in Celularity associated with the Private
Placement Shares is classified as a current asset because the investment can be liquidated to finance the Company’s current operations.

ImmunityBio

On March 9, 2021, NantKwest, Inc. and ImmunityBio (formerly known as NantCell, Inc.) completed their previously announced 100% stock-for-

stock merger (the “ImmunityBio Merger”). The combined company operates under the name ImmunityBio, Inc. and its shares of common stock
commenced trading on the Nasdaq Global Select Market on March 10, 2021 under the new ticker, “IBRX”. The former stockholders of ImmunityBio were
entitled to receive 0.8190 shares of common stock of the combined company for each outstanding share of ImmunityBio common stock held immediately
prior to the ImmunityBio Merger. Prior to the closing of the ImmunityBio Merger, the Company owned 10,000,000 shares of common stock of
ImmunityBio, and the Company therefore received 8,190,000 shares of common stock of the post-merger company.

Prior to the ImmunityBio Merger, the Company’s investment in ImmunityBio was historically included as an equity investment in its consolidated

balance sheets and accounted for as an equity security without a readily determinable fair value. As of the completion of the ImmunityBio Merger, the
Company accounted for its investment in ImmunityBio as an equity investment with a readily determinable fair value and reclassified its investment in
ImmunityBio to marketable investments within its consolidated balance sheets. The investment in ImmunityBio was classified as a current asset because
the investment was liquidated to finance the Company’s current operations. In connection with the disposal of its investment in ImmunityBio, the Company
recorded a realized gain on marketable investments of $24.1 million during the year ended December 31, 2021. The Company sold 8,190,000 shares of
ImmunityBio common stock during the year ended December 31, 2021 for net proceeds to the Company of $124.0 million. The Company had no
remaining shares of ImmunityBio common stock as of December 31, 2021.

Aardvark

F-22

During the year ended December 31, 2021, the Company paid $10.0 million in cash for an aggregate of 7,777,864 shares of Series B Preferred Stock

of Aardvark. The Company accounts for its investment in Aardvark as an equity investment without a readily determinable fair value and carries its
investment in Aardvark at cost, less impairment, plus or minus changes resulting from observable price changes in orderly transactions for identical or
similar investments. Tien Lee, MD, a member of the board of directors of Scilex Holding Company (“Scilex Holding”), a majority owned subsidiary of the
Company, is the founder and chief executive officer of Aardvark. Kim D. Janda, Ph.D., a member of the Board of Directors of the Company, is a member
of the advisory board of Aardvark.

Deverra

During the year ended December 31, 2021, the Company paid approximately $10.2 million in consideration for an aggregate of 5,622,703 shares of

common stock of Deverra, a development-stage, biotechnology company focused on developing cellular immunotherapy programs. The Company’s
payment consisted of (i) the cancellation of certain promissory notes issued by Deverra to the Company with an aggregate principal amount of $6.0 million
and unpaid accrued interest of approximately $0.1 million and (ii) a cash payment of $4.1 million. In addition, on December 7, 2021, the Company loaned
Deverra an aggregate of $1.0 million in consideration of a promissory note, which matures six months from the date of issuance. The Company initially
agreed to make additional investments in Deverra, but the Company and Deverra subsequently terminated the Company’s obligation to make such
additional investments. The Company has determined that its investment in Deverra’s common stock represents an equity method investment and that
substantially all of the fair value of the underlying assets of Deverra relates to a single IPR&D asset. The Company immediately expensed all costs
associated with the investment and the total consideration paid was expensed as acquired in-process research and development during the year ended
December 31, 2021. The Company has a variable interest in Deverra and Deverra is deemed to be a variable interest entity (“VIE”). The Company is not,
however, the primary beneficiary of the VIE as it does not have the power to direct the activities of Deverra. In connection with the Company’s purchase of
Deverra common stock, Dr. Henry Ji, the Company’s Chief Executive Officer and Chairperson, and Jaisim Shah, a member of the Company’s Board of
Directors, were appointed to the board of directors of Deverra.

Elsie

During the year ended December 31, 2021, the Company paid $10.0 million in cash for 10,000,000 shares of Series A Preferred Stock of Elsie. The

Company accounts for its investment in Elsie as an equity investment without a readily determinable fair value and carries its investment in Elsie at cost,
less impairment, plus or minus changes resulting from observable price changes in orderly transactions for identical or similar investments. In connection
with the Company's purchase of Elsie Series A Preferred Stock, Dr. Henry Ji was appointed to the board of directors of Elsie.

NANTibody

The Company’s investment in NANTibody is reported in equity method investments on its consolidated balance sheets and its share of

NANTibody’s income or loss is recorded in loss on equity method investments on its consolidated statement of operations. The Company continues to hold
40% of the outstanding equity of NANTibody and NantCell holds the remaining 60%. The Company’s investment in NANTibody had a carrying value of
zero as of December 31, 2021 due to the Company’s share of cumulative losses. The carrying value of the Company’s investment in NANTibody was
approximately $0.5 million as of December 31, 2020.

NANTibody recorded net loss of $0.7 million, $0.1 million and $2.4 million for the twelve months ended September 30, 2021, 2020 and 2019,
respectively. As of September 30, 2021, NANTibody had $2.4 million in current assets, $9.6 million in current liabilities, $0.1 million in noncurrent assets
and no noncurrent liabilities. As of September 30, 2020, NANTibody had $4.9 million in current assets, $3.5 million in current liabilities, $0.2 in
noncurrent assets and no noncurrent liabilities.

The financial statements of NANTibody are not received sufficiently timely for the Company to record its portion of earnings or loss in the current

financial statements and therefore the Company reports its portion of earnings or loss on a one quarter lag.

NantCancerStemCell (“NantStem”)

The Company’s investment in NantStem is reported in equity method investments on its consolidated balance sheets and its share of NantStem’s

income or loss is recorded in loss on equity method investments on its consolidated statement of operations. The Company is accounting for its interest in
NantStem as an equity method investment, due to the significant influence the Company has over the operations of NantStem through its board
representation and 20% voting interest. The carrying value of the Company’s investment in NantStem was approximately $18.5 million and $18.1 million
as of December 31, 2021 and 2020, respectively.

F-23

NantStem recorded a net gain of $0.1 million for the twelve months ended September 30, 2021 and 2020, respectively, and a net loss of $0.9 million

for the twelve months ended September 30, 2019. As of September 30, 2021, NantStem had $83.1 million in current assets, no current liabilities, $0.5
million in noncurrent assets and no noncurrent liabilities. As of September 30, 2020, NantStem had $80.0 million in current assets, no current liabilities,
$1.7 million in noncurrent assets and no noncurrent liabilities.

The financial statements of NantStem are not received sufficiently timely for the Company to record its portion of earnings or loss in the current

financial statements and therefore the Company reports its portion of earnings or loss on a one quarter lag.

6. Goodwill and Intangible Assets

Goodwill totaled $79.5 million as of December 31, 2021. Goodwill for the Sorrento Therapeutics segment and Scilex segment was $72.8 million
and $6.7 million, respectively, as of December 31, 2021. Goodwill increased by $35.9 million during the year ended December 31, 2021 as compared to
$43.6 million as of December 31, 2020 as a result of the Company’s acquisition of ACEA. The Company performed an annual assessment for goodwill
impairment in the fourth quarter of 2021, noting no impairment.

Amortization for the intangible assets that have finite useful lives is generally recorded on a straight-line basis over their useful lives. Intangible

assets with indefinite useful lives totaling $218.4 million are included in acquired in-process research and development in the table below. A summary of

On June 1, 2021 (the “Closing Date”), the Company completed the acquisition of ACEA pursuant to the terms of the Agreement and Plan of Merger

(the “ACEA Merger Agreement”), dated as of April 2, 2021, by and among the Company, AT Merger Sub, Inc., an exempted company incorporated with
limited liability in the Cayman Islands and wholly owned subsidiary of the Company, ACEA and Fortis Advisors LLC, as representative of the
shareholders of ACEA, whereby ACEA became a wholly owned subsidiary of the Company. With operations in both China and the United States, ACEA
is developing multiple clinical and preclinical-stage new chemical entity compounds, including the late clinical drug candidate, Abivertinib.

The total value of the consideration paid by the Company for the acquisition of ACEA was equal to $38.0 million plus approximately $1.9 million

(which amount represented the Company’s agreed upon share of certain interest, fees and other expenses) resulting in an aggregate payment of
approximately $39.9 million (which amount was subject to further adjustment for indebtedness, transaction expenses and cash, in each case pursuant to the
terms of the ACEA Merger Agreement) (the “Closing Consideration”). Pursuant to the terms of the ACEA Merger Agreement, a portion of the Closing
Consideration equal to (i) $38,059,326 was used to repay certain existing indebtedness of ACEA, which amount was paid to the holders thereof in the form
of shares of common stock of the Company and an aggregate of 5,519,469 shares (“Indebtedness Shares”) of the Company’s common stock were issued in
respect thereof based on a price per share equal to $6.8955 (representing the volume weighted average closing price per share of Common Stock, as
reported on The Nasdaq Stock Market LLC, for the 10 consecutive trading days ending on the date that was three trading days prior to the Closing Date)
and (ii) $100,000 was set aside for expenses incurred by the shareholders’ representative thereunder. The Indebtedness Shares were subject to a true-up, as
set forth in the ACEA Merger Agreement, if the price at which such shares were issued is greater than the closing price of the Company’s common stock on
the date that is six months after June 1, 2021.

In addition to the Closing Consideration, the Company will pay the ACEA equityholders (i) up to $450.0 million in additional payments, subject to

the receipt of certain regulatory approvals and achievement of certain net sales targets with respect to the assets acquired from ACEA and (ii) five to ten
percent of the annual net sales on specified royalty-bearing products (the “Earn-Out Consideration”). The fair value of the Earn-Out Consideration on the
acquisition date was preliminarily estimated to be $122.1 million. The fair value of the Earn-Out Consideration as of December 31, 2021 was $131.3
million. The amount referenced in clause (i) of the preceding sentence includes the amounts that would have otherwise been due to ACEA under that
certain License Agreement, dated July 13, 2020, between the Company and ACEA, which agreement was terminated in its entirety upon completion of the
acquisition of ACEA.

The preliminary purchase price allocation was calculated based on an upfront consideration of $44.1 million, which was based on the Company’s

closing share price on June 1, 2021. The ACEA Merger Agreement resulted in net identifiable assets of approximately $166.2 million, which includes
separate and distinct intangible assets comprised of acquired in-process research and development of $190.8 million, goodwill of $36.0 million, fair value
of debt assumed of approximately $32.1 million, deferred tax liabilities of $31.4 million and other net assets of approximately $2.9 million. The purchase
price allocation is preliminary as the Company is still completing the valuation of the intangible assets, contingent consideration, taxes, the fair value of
debt assumed and other net assets, changes to which may also increase or decrease the amount of goodwill recognized. Goodwill largely reflects the broad-
spectrum and synergistic infrastructures and expertise in pharmaceutical and biological drug discovery, development and manufacturing, and expanded
geographic coverage in China and North America and is not deductible for tax purposes. Acquisition costs related to the acquisition of ACEA were not
material. Results of operations prior to and since the date of acquisition were not material. Customary tax related matters such as the filing of pre-
acquisition tax returns are subject to finalization as of December 31, 2021, and such matters may result in adjustments to the purchase price allocation.

The Company is still in the process of finalizing the working capital adjustments and the purchase price allocation, given the size and scope of the

assets and liabilities subject to valuation. While the Company does not expect material changes in the valuation

F-25

outcome, certain assumptions and findings that were in place at the date of acquisition could result in changes in the purchase price allocation.

Asset Purchase Agreement with Aardvark Therapeutics, Inc.

In April 2021, the Company entered into an asset purchase agreement (the “Aardvark Asset Purchase Agreement”) with Aardvark to acquire

Aardvark’s Delayed Burst Release Low Dose Naltrexone (DBR-LDN), or ARD-301, asset and intellectual property rights, for the treatment of chronic
pain, fibromyalgia and chronic post-COVID syndrome. As consideration for the purchase of the assets, the Company paid Aardvark an upfront license fee
of $5.0 million comprised of 616,655 shares of the Company’s common stock, and which was expensed as acquired in-process research and development
during the year ended December 31, 2021. The Company also agreed to pay Aardvark (i) milestone payments upon the receipt of certain regulatory
approvals, and (ii) milestone payments upon the Company’s achievement of certain commercial sales milestones. The Company will also pay certain
royalties in the mid-single digit to low-double digit percentages of annual net sales by the Company. Tien Lee, MD, a member of the board of directors of
Scilex Holding, a majority owned subsidiary of the Company, is the founder and chief executive officer of Aardvark. Kim D. Janda, Ph.D., a member of the
board of directors of the Company, is a member of the advisory board of Aardvark. As discussed in Note 5, the Company holds an investment interest in
Aardvark.

2020 Acquisition

Acquisition of SmartPharm Therapeutics, Inc.

On September 1, 2020, the Company completed the acquisition of SmartPharm, a gene-encoded protein therapeutics company developing non-viral

DNA and RNA gene delivery platforms for COVID-19, Influenza and rare diseases with broad potential for application in enhancing antibody-centric
therapeutics. The total base consideration paid to the holders of capital stock of SmartPharm in the acquisition was $19.5 million, which was comprised of
approximately 1.8 million shares of the Company’s common stock.

The purchase price allocation resulted in net identifiable assets of $19.5 million, which includes separate and distinct indefinite lived intangible
assets comprised of acquired in-process research and development of $13.9 million, goodwill of $5.3 million and other net assets of $0.3 million. Goodwill
largely reflects the synergies expected to be achieved with SmartPharm’s gene delivery platforms and the assembled workforce. Goodwill is not deductible
for tax purposes. Results of operations since the date of acquisition were not material.

2019 Acquisition

Acquisition of Semnur Pharmaceuticals, Inc. (“Semnur”)

On March 18, 2019, the Company entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Semnur Pharmaceuticals, Inc.

(“Semnur”) and Scilex Holding, whereby Semnur became a wholly-owned subsidiary of Scilex Holding (the “Merger”), and thereby Scilex Holding
acquired Semnur’s SEMDEXATM (SP-102) technology for consideration valued at approximately $70.0 million, excluding contingent consideration,
transaction costs of $3.1 million and liabilities assumed of $4.2 million, which was allocated based on the relative fair value of the assets acquired. The
$70.0 million of consideration consisted of approximately $15.0 million in cash and shares of Scilex Holding valued at approximately $55.0 million (the
“Stock Consideration”). Following the issuance of the Stock Consideration, the Company’s ownership in Scilex Holding was diluted to approximately 58%
of Scilex Holding’s issued and outstanding capital stock.

Pursuant to the Merger Agreement, Scilex Holding also agreed to pay the holders of Semnur’s capital stock and options (the “Semnur

Equityholders”) up to $280.0 million in aggregate contingent cash consideration based on the achievement of certain milestones, which is comprised of a
$40.0 million payment that will be due upon obtaining the first approval of a New Drug Application of a Semnur product by the U.S. Food and Drug
Administration (the “FDA”) and additional payments that will be due upon the achievement of certain amounts of net sales of Semnur products as follows:
(a) a $20.0 million payment upon the achievement of $100.0 million in cumulative net sales of a Semnur product, (b) a $20.0 million payment upon the
achievement of $250.0 million in cumulative net sales of a Semnur product, (c) a $50.0 million payment upon the achievement of $500.0 million in
cumulative net sales of a Semnur product, and (d) a $150.0 million payment upon the achievement of $750.0 million in cumulative net sales of a Semnur
product.

In March 2019, the Company also entered into an Exchange and Registration Rights Agreement (the “Exchange Agreement”) with the Semnur

Equityholders. Pursuant to the Exchange Agreement, if within 18 months of the closing of the Merger, 100% of the outstanding equity of Scilex Holding
had not been acquired by a third party or Scilex Holding had not entered into a definitive agreement with respect to, or otherwise consummated, a firmly
underwritten offering of Scilex Holding’s capital stock that meets certain requirements and includes the Stock Consideration, then the Semnur
Equityholders could collectively elect to exchange, during

F-26

the 60-day period commencing the date that is the 18 month anniversary of the closing of the Merger, the Stock Consideration for shares of the Company’s
common stock with a value of $55.0 million (the “Semnur Share Exchange”) based on a price per share of the Company’s common stock equal to the
greater of (a) the 30-day trailing volume weighted average price of one share of the Company’s common stock as reported on the Nasdaq Capital Market as
of the consummation of the Semnur Share Exchange and (b) $5.55 (subject to adjustment for any stock dividend, stock split, stock combination,
reclassification or similar transaction) (the “Exchange Price”). On September 28, 2020, the Company entered into an amendment to the Exchange
Agreement to, among other things, provide that if the Company received notice from the Semnur Equityholders that they will proceed with the Semnur
Share Exchange (the “Exchange Notice”), the Company could, in its sole discretion, elect, within seven days of receipt of the Exchange Notice, to
exchange all the Stock Consideration and the rights to receive cash from Scilex Holding held by the Semnur Equityholders for an amount in cash equal to
$55.0 million, in lieu of issuing $55.0 million of shares of the Company’s common stock at the Exchange Price. On September 28, 2020, the Semnur
Equityholders delivered the Exchange Notice to the Company. On October 5, 2020, the Company notified the Semnur Equityholders of its election to pay
cash, and paid $55.0 million in cash to the Semnur Equityholders and effectuated the Semnur Share Exchange on October 9, 2020. Following the
completion of the Semnur Share Exchange and as of December 31, 2020, the Company held approximately 82.3% of the outstanding common stock of
Scilex Holding. On January 29, 2021, the Company acquired additional shares of Scilex Holding in exchange for 2,567,456 shares of the Company’s stock,
resulting in the Company holding approximately 99.9% of the outstanding common stock of Scilex Holding. As of December 31, 2021, the Company held
approximately 99.9% of the outstanding common stock of Scilex Holding.

The transaction was accounted for as an asset acquisition since substantially all the value of the gross assets was concentrated in a single asset. No
contingent consideration was recorded as of December 31, 2019 and 2020 since the related regulatory approval milestones are not deemed probable until
they actually occur. Approximately $75.3 million was expensed as acquired in-process research and development during the year ended December 31,
2019.

to such termination are currently pending in an arbitration before the American Arbitration Association (See the information under the heading “Litigation”
in Note 11 for additional information). The Company has therefore deferred recognition of the upfront payment and the value of the equity interest received
until the arbitration is concluded or resolved. On March 9, 2021, NantKwest, Inc. and ImmunityBio (formerly known as NantCell, Inc.) completed their
previously announced 100% stock-for-stock merger (See Note 5).

8. Debt

2018 Purchase Agreements and Indenture for Scilex

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

The net proceeds of the Offering were approximately $89.3 million, after deducting the Offering expenses payable by Scilex Pharma and funding a

segregated reserve account ($20.0 million) (the “Reserve Account”) and a segregated collateral account ($25.0 million) (the “Collateral Account”) pursuant
to the terms of the Indenture. Funds in the Reserve Account were to be released to Scilex Pharma upon receipt by the Trustee of an officer’s certificate
under the Indenture from Scilex Pharma confirming receipt of a marketing approval letter from the FDA with respect to SP-103 (the “Marketing Approval
Letter”) on or prior to July 1, 2023. Funds in the Collateral Account were to be released upon receipt of a written consent authorizing such release from the
holders of a majority in principal amount of the Scilex Notes issued, upon the occurrence and during the continuance of an event of default at the direction
of the holders of a majority in principal amount of the Scilex Notes issued or upon the repayment in full of all amounts owed under the Scilex Notes.

The holders of the Scilex Notes were initially entitled to receive quarterly payments of principal of the Scilex Notes equal to a percentage, in the

range of 10% to 20% of the net sales of ZTlido for the prior fiscal quarter, beginning on February 15, 2019. However, because Scilex Pharma did not
receive the Marketing Approval Letter by March 31, 2021, the percentage of net sales payable was increased to be in the range of 15% to 25%. If actual
cumulative net sales of ZTlido from October 1, 2022 through September 30, 2023 are less than 60% of a predetermined target sales threshold for such
period, then Scilex Pharma will be obligated to pay an additional installment of principal of the Scilex Notes each quarter in an amount equal to an amount
to be determined by reference to the amount of such deficiency.

The aggregate principal amount due under the Scilex Notes was to be increased by $28,000,000 on February 15, 2022 if actual cumulative net sales

of ZTlido from the issue date of the Scilex Notes through December 31, 2021 do not equal or exceed 95% of a predetermined target sales threshold for such
period. If actual cumulative net sales of ZTlido for the period from October 1, 2022 through September 30, 2023 do not equal or exceed 80% of a
predetermined target sales threshold for such period, the aggregate principal amount shall also be increased on November 15, 2023 by an amount equal to
an amount to be determined by reference to the amount of such deficiency.

The final maturity date of the Scilex Notes will be August 15, 2026. The Scilex Notes may be redeemed in whole at any time upon 30 days’ written

notice at Scilex Pharma’s option prior to August 15, 2026 at a redemption price equal to 100% of the then-outstanding principal amount of the Scilex
Notes. In addition, upon a change of control of Scilex Pharma (as defined in the Indenture),

F-29

each holder of a Scilex Note shall have the right to require Scilex Pharma to repurchase all or any part of such holder’s Scilex Note at a repurchase price in
cash equal to 101% of the then-outstanding principal amount thereof.

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

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

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

Pursuant to a Collateral Agreement by and among Scilex Pharma, the Trustee and the Collateral Agent (the “Collateral Agreement”), the Scilex

Notes will be secured by ZTlido and all of the existing and future property and assets of Scilex Pharma necessary for, or otherwise relevant to, now or in
the future, the manufacture and sale of ZTlido, on a worldwide basis (exclusive of Japan), including, but not limited to, the intellectual property related to
ZTlido, the marketing or similar regulatory approvals related to ZTlido, any licenses, agreements and other contracts related to ZTlido, and the current
assets related to ZTlido such as inventory, accounts receivable and cash and any and all future iterations, improvements or modifications of such product
made, developed or licensed (or sub-licensed) by Scilex Pharma or any of its affiliates or licensees (or sub-licensees) (including SP-103).

Pursuant to the terms of the Indenture, the Company issued an irrevocable standby letter of credit to Scilex Pharma (the “Letter of Credit”), which

provides that, in the event that (1) Scilex Pharma does not hold at least $35,000,000 in unrestricted cash (which is inclusive of the amount in the Collateral
Account) as of the end of any calendar month during the term of the Scilex Notes, (2) actual cumulative net sales of ZTlido from the issue date of the
Scilex Notes through December 31, 2021 are less than a specified sales threshold for such period, or (3) actual cumulative net sales of ZTlido for any
calendar year during the term of the Scilex Notes, beginning with the 2022 calendar year, are less than a specified sales threshold for such calendar year,
Scilex Pharma as beneficiary of the Letter of Credit, will draw, and the Company will pay to Scilex Pharma, $35,000,000 in a single lump-sum amount as a
subordinated loan. In the event that Scilex Pharma draws on, and the Company pays to Scilex Pharma, $35,000,000 in a single lump-sum amount as a
subordinated loan, each holder of the Scilex Notes had the right to require the Company to purchase all or any part of such holder’s outstanding Scilex
Notes in the principal amount of, and at a purchase price in cash equal to, $25,000,000 multiplied by such holder’s pro rata portion of the then-outstanding
Scilex Notes. The Letter of Credit will terminate upon the earliest to occur of: (a) the repayment of the Scilex Notes in full, (b) the actual net sales of
ZTlido for any calendar year during the term of the Scilex Notes exceeding a certain threshold, (c) the consummation of an initial public offering on a
major international stock exchange by Scilex Pharma that satisfies certain valuation thresholds, and (d) the replacement of the Letter of Credit with another
letter of credit in form and substance, including as to the identity and creditworthiness of issuer, reasonably acceptable to the holders of at least 80% in
principal amount of outstanding Scilex Notes.

On December 14, 2020, Scilex Pharma, the Company, the Trustee and the Agent, and the beneficial owners of the Scilex Notes and the Scilex Note

Purchasers entered into a Consent Under and Amendment No. 3 to Indenture and Letter of Credit (the “Amendment”), which amended: (i) the Indenture,
and (ii) the Letter of Credit.

Pursuant to the Amendment, the Scilex Note Purchasers agreed to release all of the aggregate $45.0 million in restricted funds held in the Reserve

Account and the Collateral Account for the purpose of consummating the repurchase of an aggregate of $45.0 million of principal amount of the Scilex
Notes from the Holders on a pro rata basis at a purchase price equal to 100% of the principal amount thereof (such repurchase, the “Effective Date
Repurchase”). In connection with the Effective Date Repurchase, the parties also agreed to remove Scilex Pharma’s obligations under the Indenture to (i)
repurchase $25.0 million of Scilex Notes from the holders if the Letter of Credit is drawn on, and (ii) repurchase $20.0 million of the Scilex Notes from the
holders if Scilex Pharma does not receive the Marketing Approval Letter on or prior to July 1, 2023.

The Amendment also revised the minimum cash covenant in the Indenture to provide that the amount of cash equivalents in bank accounts that

Scilex Pharma is required to have as of the end of any calendar month shall, commencing with the month ending December 31, 2020, be equal to at least
$4.0 million in the aggregate, provided that if Scilex Pharma did not effectuate (i) the

F-30

December Optional Repurchase (as defined below) and (ii) at least one of either (x) the February Optional Repurchase (as defined below) or (y) the April
Optional Repurchase (as defined below), then, commencing with the month ending April 30, 2021, and for each month thereafter, such amount would be at
least $10.0 million in the aggregate. If Scilex Pharma fails to meet the foregoing minimum cash requirements, then Scilex Pharma will be required to draw
on the Letter of Credit.

The Amendment also provided Scilex Pharma with the option, in its sole and absolute discretion, to repurchase Scilex Notes from the holders
thereof on a pro rata basis on each of December 16, 2020 (the “December Optional Repurchase”), February 12, 2021 (the “February Optional Repurchase”)
and April 13, 2021 (the “April Optional Repurchase” and, together with the December Optional Repurchase and the February Optional Repurchase, the
“Optional Repurchases”), in each case in an aggregate amount equal to the lesser of $20.0 million or the then-outstanding principal amount of Scilex Notes,
at a purchase price in cash equal to 100% of the principal amount thereof.

The Amendment further provides that in the event that the Letter of Credit is drawn upon by Scilex Pharma, then Scilex Pharma shall, within five

business days of such draw, repurchase Scilex Notes from the holders thereof on a pro rata basis in an aggregate amount equal to the lesser of $20.0 million
or the then-outstanding principal amount of the Scilex Notes, at a purchase price in cash equal to 100% of the principal amount thereof. In addition, upon
the Letter of Credit being drawn on, Scilex Pharma will be required to have minimum cash of $10.0 million at all times thereafter.

Pursuant to the Amendment, the Holders also consented to Scilex Pharma incurring up to $10.0 million of indebtedness in connection with an

accounts receivable revolving loan facility with another lender and the incurrence of liens and the pledge of collateral to such lender in connection
therewith.

On December 14, 2020, the restricted funds in the Reserve Account and the Collateral Account were released and the Effective Date Repurchase

was effected. Scilex Pharma also effectuated the December Optional Repurchase on December 16, 2020. Following the Effective Date Repurchase and the
December Optional Repurchase, the aggregate principal amount of the Scilex Notes was reduced by an aggregate of $65.0 million. The Company
accounted for the Amendment as a debt modification under ASC Topic 470-50 as the modified terms were not substantially different than the pre-modified
terms.

Scilex Pharma effectuated the February Optional Repurchase and the April Optional Repurchase, which reduced the aggregate principal by $40.0

million during the year ended December 31, 2021. In connection with the repurchases, the Company recorded a loss on partial debt extinguishment of
$14.0 million during the year ended December 31, 2021.

Actual cumulative net sales of ZTlido from the issue date of the Scilex Notes through December 31, 2021 did not equal or exceed 95% of a

predetermined target sales threshold for such period, which resulted in a $28.0 million increase in the principal amount of the Scilex Notes, effective
February 15, 2022. As a result, the Company recorded the increase of $28.0 million in principal and non-operating expense at December 31, 2021.

Effective February 14, 2022, Scilex Pharma issued to the Company a draw notice under the Letter of Credit as required under the terms of the
Indenture because actual cumulative net sales of ZTlido from the issue date of the Scilex Notes through December 31, 2021 were less than a specified sales
threshold for such period. As a result of the draw notice being issued, the Company paid to Scilex Pharma $35,000,000 in a single lump-sum amount as a
subordinated loan. Per the terms of the Amendment, in February 2022, Scilex Pharma repurchased Scilex Notes from the holders thereof on a pro rata basis
in an aggregate amount equal to $20.0 million at a purchase price in cash equal to 100% of the principal amount thereof.

To estimate the fair value of the Scilex Notes, the Company uses the discounted cash flow method under the income approach, which involves
significant Level 3 inputs and assumptions, combined with a Monte Carlo simulation as appropriate. The value of the debt instrument is based on the
present value of future principal payments and the discounted rate of return reflective of the Company’s credit risk.

The Company made principal payments of $45.9 million and $69.8 million during the fiscal years ended December 31, 2021 and 2020, respectively.

Debt discount and debt issuance costs, which are presented as a direct reduction of the Scilex Notes in the consolidated balance sheets, are amortized as
interest expense using the effective interest method. As principal repayments on the Scilex Notes are based on a percentage of net sales of ZTlido and SP-
103, if the Marketing Approval Letter is received, the Company has elected to account for changes in estimated cash flows from future net sales
prospectively. Specifically, a new effective interest rate will be determined based on revised estimates of remaining cash flows and changes in expected
cash flows will be recognized prospectively. The imputed effective interest rate at December 31, 2021 was 7.7 %. The amount of debt discount and debt
issuance costs included in interest expense for the fiscal years ended December 31, 2021, 2020 and 2019 was approximately $7.9 million, $10.6 million
and $15.0 million, respectively.

The Company identified a number of embedded derivatives that require bifurcation from the Scilex Notes and that were separately accounted for in

the consolidated financial statements as derivative liabilities. Certain of these embedded features include default interest provisions, contingent rate
increases, contingent put options, optional and automatic acceleration provisions and tax indemnification obligations. The fair value of the derivative
liabilities associated with the Scilex Notes was estimated using the discounted cash flow method under the income approach combined with a Monte Carlo
simulation model. This involves significant Level 3 inputs and assumptions, including a risk adjusted net sales forecast, an effective debt yield, estimated
marketing approval probabilities for SP-103 and an estimated probability of an initial public offering by Scilex Holding that satisfies certain valuation
thresholds and timing considerations. The Company re-evaluates this assessment each reporting period.

The 2018 Purchase Agreements and Indenture, as amended, provide that, upon the occurrence of an event of default, the lenders thereunder may, by

written notice to the Company, declare all of the outstanding principal and interest under the Indenture immediately due and payable. For purposes of the
Indenture, an event of default includes, among other things, (i) a failure to pay any amounts when due under the Indenture, (ii) a breach or other failure to
comply with the covenants (including financial, notice and reporting covenants) under the Indenture, (iii) a failure to make any payment on, or other event
triggering an acceleration under, other material indebtedness of the Company, and (iv) the occurrence of certain insolvency or bankruptcy events (both
voluntary and involuntary) involving the Company or certain of its subsidiaries. The Company is subject to certain customary default clauses under the
Indenture and is in compliance with event of default clauses under the Indenture.

Effective February 15, 2022, in accordance with the Indenture, the principal amount of the Scilex Notes was increased by $28.0 million because

actual cumulative net sales of ZTlido from the issue date of the Scilex Notes through December 31, 2021 did not equal or exceed 95% of a predetermined
target sales threshold for such period.

2018 Oaktree Term Loan Agreement

In November 2018, the Company entered into a Term Loan Agreement (the “Loan Agreement”) with certain funds and accounts managed by

Oaktree Capital Management, L.P. (collectively, the “Lenders”) and Oaktree Fund Administration, LLC, as

F-32

administrative and collateral agent, for an initial term loan of $100.0 million (the “Initial Loan”). In May 2019, the Company entered into an amendment to
the Loan Agreement, under which terms the Lenders agreed to make available to the Company $20.0 million (the “Early Conditional Loan”, and
collectively, with the Initial Loan, the “Term Loans”). The Initial Loan matured on November 7, 2023 and bore interest at a rate equal to the London
Interbank Offered Rate plus the applicable margin, or 7%. In connection with the Loan Agreement, on November 7, 2018, the Company issued to the
Lenders warrants to purchase 6,288,985 shares of the Company’s common stock (the “Initial Warrants”). The Initial Warrants have an exercise price per
share of $3.28 and will be exercisable from May 7, 2019 through May 7, 2029.

In connection with the May 2019 amendment, the Company issued to the Lenders warrants to purchase an aggregate of 1,333,304 shares of the
Company’s common stock (the “2019 Warrants”). The 2019 Warrants have an exercise price per share of $3.94, subject to adjustment for stock splits,
reverse stock splits, stock dividends and similar transactions, and are exercisable from November 3, 2019 through November 3, 2029. The Company
recorded a loss on derivative liabilities associated with the 2019 Warrants of $4.3 million on the issuance date.

During the year ended December 31, 2020, the Company repaid $120.0 million of outstanding principal under the Term Loans plus approximately

$9.4 million of related prepayment premium, exit fees and accrued interest thereon. In connection with the repayment of outstanding principal, the
Company recorded a loss on debt settlement of $51.9 million.

Interest expense recognized for stated interest on the Term Loans totaled $3.0 million and $10.7 million and for the years ended December 31, 2020

and 2019, respectively. Debt discount and debt issuance costs were amortized as interest expense using the effective interest method. The amount of debt
discount and debt issuance costs included in interest expense on the Term Loans for the years ended December 31, 2020 and 2019 was approximately $2.2
million and $5.5 million, respectively.

2018 Securities Purchase Agreement for Private Placement

In March 2018, the Company entered into a Securities Purchase Agreement (the “March 2018 Securities Purchase Agreement”) with certain

investors (the “March 2018 Purchasers”), in which the Company issued and sold to the March 2018 Purchasers, (1) convertible promissory notes in an
aggregate principal amount of $120,500,000 (the “Notes”), and (2) warrants to purchase 8,591,794 shares of the Company’s common stock (the
“Warrants”). In June 2018, the Company entered into an amendment (the “June 2018 Amendment”), in which the Company issued and sold to the March

2019 Stock Incentive Plan

In September 2019, the Company’s stockholders approved the Sorrento Therapeutics, Inc. 2019 Stock Incentive Plan (the “2019 Plan”). The 2019
Plan replaced and superseded the Company’s Amended and Restated 2009 Stock Incentive Plan (the “2009 Plan”) and no further awards will be granted
under the 2009 Plan. The 2019 Plan provides for the grant of incentive stock options, non-incentive stock options, stock appreciation rights, restricted stock
awards, unrestricted stock awards, restricted stock unit awards and performance awards to eligible recipients. Recipients of stock options shall be eligible to
purchase shares of the Company’s common stock at an exercise price equal to no less than the estimated fair market value of such stock on the date of
grant. The maximum term of options granted under the Stock Plan is ten years. Employee option grants generally vest 25% on the first anniversary of the
original vesting commencement date, with the balance vesting monthly over the remaining three years.

The following table summarizes stock option activity as of December 31, 2021 under the 2019 Plan and the 2009 Plan, and the changes for the

period then ended (dollar values in thousands, other than weighted-average exercise price):

The assumed dividend yield was based on the Company’s expectation of not paying dividends in the foreseeable future. The expected volatility is

based on the historical volatility of the Company's stock. The risk-free interest rate is based on the U.S. Treasury yield curve over the expected term of the
option. The weighted average expected life of options was estimated using the average of the contractual term and the weighted average vesting term of the
options.

Under the 2019 Plan and the Company’s prior equity award and option plans, total stock-based compensation recorded as operating expense was

$29.7 million, $15.0 million and $8.3 million for the years ended December 31, 2021, 2020 and 2019, respectively. The total unrecognized compensation
cost related to unvested employee and director stock option grants as of December 31, 2021 was $86.7 million and the weighted average period over which
these grants are expected to vest is 2.8 years.

Employee Stock Purchase Plan

On October 16, 2020 at the Company’s 2020 Annual Meeting of Stockholders (the “Annual Meeting”), the Company’s stockholders approved the
Company’s 2020 Employee Stock Purchase Plan (“ESPP”). Under the terms of the ESPP, the Company’s employees can elect to have up to 15% of their
annual compensation, up to a maximum of $25,000 per year, withheld to purchase shares of the Company’s common stock for a purchase price equal to
85% of the lesser of the fair market value per share (at closing) of the Company’s common stock on (i) the commencement date of the six-month offering
period, or (ii) the respective purchase date. The initial offering period commenced on November 6, 2020 and ended on May 5, 2021, with subsequent
offering periods commencing on May 6th of each year and ending on November 5th of the following year. Total stock-based compensation recorded as
operating expense for the ESPP was $1.1 million and $0.2 million for the years ended December 31, 2021 and 2020, respectively.

F-36

CEO Performance Award

On August 7, 2020, the Compensation Committee of the Company`s Board of Directors (the “Compensation Committee”) approved a grant to

Henry Ji, Ph.D., the Company’s Chairman of the Board, Chief Executive Officer and President, of a 10-year CEO performance award tied solely to
achieving market capitalization milestones (the “CEO Performance Award”), subject to approval of the Company’s stockholders at the Annual Meeting.
The CEO Performance Award consists of a 10-year option to purchase an aggregate of 24,935,882 shares of the Company’s common stock, which was
equal to 10% of the Company’s outstanding shares of common stock on the day prior to the date of grant, and vests in ten tranches. Each of the ten tranches
vests only if a market capitalization milestone is achieved, which requires two market capitalization prongs to be met to achieve each milestone: (1) a six
calendar month trailing average (based on trading days); and (2) a 30 calendar day trailing average (based on trading days). To meet the first market
capitalization milestone, the Company’s current market capitalization must increase to $5.0 billion. For the next two milestones, the Company’s market
capitalization must continue to increase in additional $2.0 billion increments. For the three milestones thereafter, the Company’s market capitalization must
increase in additional $3.0 billion increments. For the next three milestones thereafter, the Company’s market capitalization must increase in additional $4.0
billion increments. For the final milestone, the Company’s market capitalization must increase by an additional $5.0 billion. Thus, for Dr. Ji to fully vest in
the award, the Company’s market capitalization must increase to $35.0 billion. The exercise price per share subject to the CEO Performance Award is
$17.30, which is a 20% premium to the closing sales price of the Company’s common stock on August 7, 2020, the date the CEO Performance Award was
approved by the Compensation Committee. The CEO Performance Award was approved by the Company`s stockholders at the Annual Meeting held on
October 16, 2020, which represents the date of grant for accounting purposes.

Recognition of stock-based compensation expense of all the tranches commenced on the date of grant, as the probability of meeting the ten market

capitalization milestones is not considered in determining the timing of expense recognition. The expense will be recognized ratably over the expected
vesting period of each respective tranche. If the related market capitalization milestone is achieved earlier than its expected achievement period, then the
stock-based compensation expense for that vesting tranche will be accelerated and recorded in the period in which the associated milestone is achieved.
The market capitalization requirement is considered a market condition under FASB ASC Topic 718 Compensation – Stock Compensation and is estimated
on the grant date using Monte Carlo simulations. Key assumptions for estimating the performance-based awards fair value at the date of grant included,
volatility of the Company’s common stock price, post-vesting exercise behavior, and the derived service period.

Total stock-based compensation recorded as operating expense for the CEO Performance Award was $51.8 million and $10.8 million for the year
ended December 31, 2021 and 2020, respectively. As of December 31, 2021, the Company had approximately $87.7 million of total unrecognized stock-
based compensation expense remaining under the CEO Performance Award if all market capitalization milestones are achieved. The assumptions used in
determining this valuation included an expected volatility of 91.0%, a dividend yield of zero, a risk-free interest rate of 0.75%, and an expected remaining
term of 9.8 years. As of December 31, 2021, the expected remaining term is 8.8 years.

Common Stock Reserved for Future Issuance

As of December 31, 2021, approximately 77.3 million shares of common stock were reserved for future issuance, comprised of 16.0 million shares
for common stock warrants, 24.9 million for the CEO Performance Award, 7.2 million reserved for issuance under the ESPP plan and approximately 25.9
million shares under stock incentive plans. As of December 31, 2021, approximately 3.2 million shares of common stock remained available for grant
under the 2019 Plan.

Employee Benefit Plan

The Company maintains a defined contribution 401(k) plan available to eligible employees. Employee contributions are voluntary and are
determined on an individual basis, limited to the maximum amount allowable under federal tax regulations. The Company made matching contributions to
the 401(k) plan totaling $1.7 million, $1.4 million and $1.3 million, for the years ended December 31, 2021, 2020 and 2019, respectively.

11. Commitments and Contingencies

Litigation

In the normal course of business, the Company may be named as a defendant in one or more lawsuits. Other than as set forth below, the Company is
not a party to any outstanding material litigation and management is currently not aware of any legal proceedings that, individually or in the aggregate, are
deemed to be material to the Company’s financial condition or results of operations.

F-37

On April 3, 2019, the Company filed two legal actions against, among others, Patrick Soon-Shiong and entities controlled by him, asserting claims
for, among other things, fraud and breach of contract, arising out of Dr. Soon-Shiong’s purchase of the drug Cynviloq™ from the Company in May 2015.
The actions allege that Dr. Soon-Shiong and the other defendants, among other things, acquired the drug Cynviloq™ for the purpose of halting its
progression to the market. Specifically, the Company has filed:

•

An arbitration demand with the American Arbitration Association in Los Angeles, California against NantPharma, LLC (“NantPharma”) and
Chief Executive Officer Patrick Soon-Shiong, related to alleged fraud and breaches of the Stock Sale and Purchase Agreement, dated May
14, 2015, entered into between NantPharma and the Company, filed as Exhibit 10.2 to the Company’s Quarterly Report on Form 10-Q filed
with the Securities and Exchange Commission on August 7, 2015. On May 24, 2019, NantCell, Inc., Dr. Soon-Shiong and Immunotherapy
NANTibody LLC (“NANTibody”) General Counsel Charles Kim filed a motion in the Los Angeles Superior Court to stay or dismiss the
Company’s arbitration demand. On October 9, 2019, the Los Angeles Superior Court denied the motion to stay or dismiss the arbitration
demand, and the arbitration is ongoing against NantPharma. On March 5, 2020, the Company filed a legal action against Dr. Soon-Shiong in
Los Angeles Superior Court, asserting claims for fraudulent inducement and common law fraud, arising out of Dr. Soon-Shiong’s purchase of
the drug Cynviloq™ from the Company in May 2015. The action alleges that, among other things, Dr. Soon-Shiong acquired the drug
Cynviloq™ for the purpose of halting its progression to the market. In connection with filing this civil action in the Los Angeles Superior
Court, where the Company will have the right to a jury trial against Dr. Soon-Shiong, the Company has dismissed Dr. Soon-Shiong from the
related, ongoing arbitration against NantPharma; and

An action in the Los Angeles Superior Court derivatively on behalf of NANTibody against NantCell, Inc., NANTibody Board Member and
NantCell, Inc. Chief Executive Officer Patrick Soon-Shiong, and NANTibody officer Charles Kim, related to several breaches of the June 11,
2015 Limited Liability Company Agreement for NANTibody entered into between the Company and NantCell, Inc. The suit also alleges
breaches of fiduciary duties and seeks, inter alia, a declaration that the Assignment Agreement entered into on July 2, 2017, between
NantPharma and NANTibody is void and an equitable unwinding of the Assignment Agreement. The suit calls for the restoration of $90.05
million to the NANTibody capital account, thereby restoring the Company’s equity method investment in NANTibody to its invested amount
as of June 30, 2017 of $40.0 million. On May 24, 2019, NantCell, Inc. and Dr. Soon-Shiong filed a cross-complaint against the Company and
Dr. Henry Ji, seeking unspecified damages, as well as additional punitive damages and specific performance, related to alleged fraud, alleged
breaches of the Exclusive License Agreement for certain antibodies (dated June 11, 2015 and entered into between NANTibody, LLC and the
Company), and alleged tortious interference with contract. On May 24, 2019, NANTibody and NantPharma filed a new complaint in the
action against the Company and Dr. Henry Ji, seeking unspecified damages, as well as additional punitive damages and specific performance,
related to alleged fraud, alleged breaches of the Stock Sale and Purchase Agreement, alleged breaches of the Exclusive License Agreement
for certain antibodies (dated April 21, 2015 and entered into between NantCell, Inc. and the Company), and alleged tortious interference with
contract. On July 8, 2019, the Company and Dr. Henry Ji filed motions to compel the cross-complaint and new action to arbitration. On
October 9, 2019, the Los Angeles Superior Court granted the motions to compel to arbitration all of the claims brought by NANTibody,
NantCell, Inc. and NantPharma, and denied the motions to compel as to the claims brought by Dr. Soon-Shiong. Subsequently, NANTibody,
NantCell, Inc., and NantPharma have re-filed their claims in arbitration with the American Arbitration Association. On May 4, 2020, the
Company filed counterclaims against NANTibody and NantPharma related to breaches of the April 21, 2015 and June 11, 2015 Exclusive
License Agreements. The claims against Dr. Soon-Shiong have been stayed pending resolution of the claims filed in arbitration. The original
derivative action is no longer stayed, and the parties are currently engaged in discovery in the suit.

F-38

On May 26, 2020, Wasa Medical Holdings filed a putative federal securities class action in the U.S. District Court for the Southern District of
California, Case No. 3:20-cv-00966-AJB-DEB, against the Company, its President, Chief Executive Officer and Chairman of the Board of Directors, Henry
Ji, Ph.D., and its SVP of Regulatory Affairs, Mark R. Brunswick, Ph.D. The action alleges that the Company, Dr. Ji and Dr. Brunswick made materially
false and/or misleading statements to the investing public by publicly issuing false and/or misleading statements regarding STI-1499 and its ability to
inhibit the SARS-CoV-2 virus infection and that such statements violated Section 10(b) of the Securities Exchange Act of 1934, as amended, and Rule 10b-
5 promulgated thereunder. The suit seeks to recover damages caused by the alleged violations of federal securities laws, along with the plaintiffs’
reasonable costs and expenses incurred in the lawsuit, including counsel fees and expert fees. On June 11, 2020, Jeannette Calvo filed a second putative
federal securities class action in the U.S. District Court for the Southern District of California, Case No. 3:20-cv-01066-JAH-WVG, against the same
defendants alleging the same claims and seeking the same relief. On February 12, 2021, the U.S. District Court for the Southern District of California
issued an order consolidating the cases and appointing a lead plaintiff, Andrew Zenoff (“Plaintiff”), and lead counsel. On April 5, 2021, Plaintiff filed a
consolidated amended complaint in accordance with the U.S. District Court for the Southern District of California’s scheduling order. Pursuant to that
scheduling order, the defendants filed a motion to dismiss on May 20, 2021 and Plaintiff filed its opposition to the motion on July 2, 2021. The defendants’
reply was filed on August 4, 2021. On or about November 18, 2021, the U.S. District Court for the Southern District of California issued an order granting
the motion to dismiss with leave to amend. On November 30, 2021, Plaintiff filed a first amended consolidated complaint. On December 30, 2021, the
defendants filed a motion to dismiss the first amended consolidated complaint. Pursuant to a stipulated scheduling order, the defendants filed their
opposition to the motion on February 7, 2022, and the defendants filed their reply on February 28, 2022. A hearing is scheduled for the motion on May 19,
2022. The Company is defending these matters vigorously.

On July 26, 2021, Sachin Chaudhari filed a verified stockholder derivative complaint in the U.S. District Court for the Southern District of
California, Case No. 0723211, against Dr. Ji, Mr. Brunswick, and the Company’s Board of Directors as defendants, and against the Company, as a nominal
defendant. The action alleges, among other things, that defendants breached their fiduciary duties, violated Section 20(a) of the Securities Exchange Act of
1934, as amended, engaged in waste and were unjustly enriched in connection with the alleged false and misleading statements to the investing public by
publicly issuing false and/or misleading statements regarding STI-1499 and its ability to inhibit the SARS-CoV-2 virus infection. The suit seeks to recover
on behalf of the Company those damages caused by the alleged breaches of duty and related claims, along with the plaintiffs’ reasonable costs and
expenses incurred in the lawsuit, including counsel fees and expert fees. On July 27, 2021, Michael Sabatina filed a verified stockholder derivative
complaint in the Delaware Chancery Court, Case No. 2021-0654 against Dr. Ji and Mr. Brunswick, as defendants, and against the Company as a nominal
defendant, alleging the same general claims and seeking the same general relief. Both of these derivative cases have been stayed by their respective courts
pending resolution of the motion to dismiss the federal securities class action described above. The Company is defending these matters vigorously.

Operating Leases

The Company leases administrative, research and development, sales and marketing and manufacturing facilities under various non-cancelable lease

agreements. Facility leases generally provide for periodic rent increases, and many contain escalation clauses and renewal options. As of December 31,
2021, the Company’s leases have remaining lease terms of approximately 0.5 to 16.8 years, some of which include options to extend the lease terms for up
to five years, and some of which allow for early termination. Many of the Company’s leases are subject to variable lease payments. Variable lease payments
are recognized in the period in which the obligation for those payments are incurred, are not included in the measurement of the ROU assets or lease
liabilities and are immaterial. As of December 31, 2021, the Company has no finance leases.

Operating lease costs were approximately $12.5 million, $10.1 million and $10.0 million for the years ended December 31, 2021, 2020 and 2019,

respectively, and were primarily comprised of long-term operating lease costs. Short-term operating lease costs were immaterial. Supplemental quantitative

The Company has evaluated the available evidence supporting the realization of its gross deferred tax assets, including the amount and timing of

future taxable income, and has determined that it is more likely than not that the deferred tax assets will not be realized. Due to such uncertainties
surrounding the realization of the domestic deferred tax assets, the Company maintains a valuation allowance of $261.2 million against its deferred tax
assets as of December 31, 2021. Realization of the deferred tax assets will be primarily dependent upon the Company's ability to generate sufficient taxable
income prior to the expiration of its net operating losses. The change in valuation allowance also included approximately $41.6 million in 2021 and $8.1
million in 2019 attributable to the ACEA Therapeutics, Inc. and Semnur Pharmaceuticals, Inc. acquisitions, respectively.

As of December 31, 2021, the Company had $788.5 million, $246.4 million and $3.6 million of federal, state and foreign net operating loss
carryforwards, respectively. The net operating loss carryforwards begin to expire in 2035, 2029 and 2024 for federal, state and foreign, respectively.

The Company also had research and development and orphan drug income tax credits of $27.3 million and $17.9 million for federal and state,

respectively. The federal income tax credits begin to expire in 2030, while the state income tax credits carryforward indefinitely.

Internal Revenue Code Section 382 rules apply to limit a corporation's ability to utilize existing net operating loss and tax credit carryforwards once
the corporation experiences an ownership change as defined in Section 382. The Company has undergone an ownership change in a prior year. For the year
ended December 31, 2021, there was no impact of such limitations on the Company’s income tax provision.

The Company is subject to taxation in the U.S., various state tax jurisdictions and various foreign tax jurisdictions. The Company's tax years starting

on January 1, 2007 through December 31, 2021 are open and subject to examination by the U.S. and state taxing authorities due to the carryforward of net
operating losses and research and development credits. There are no active audits as of December 31, 2021.

A reconciliation of the beginning and ending amount of unrecognized tax expense (benefits) is as follows for the years ended December 31, 2021,

2020 and 2019 (in thousands):

At December 31, 2021, 2020 and 2019, $8.3 million, $5.6 million and $4.4 million, respectively, of the Company’s total unrecognized tax benefits,

if recognized, would impact the effective tax rate, however given the full valuation allowance in the jurisdiction in which the unrecognized tax benefits
relate to, the impact on the effective tax rate would be nil.

F-42

The Company’s policy is to recognize interest and penalties related to income tax matters in income tax expense. No interest or penalties have been

recognized as of and for the periods ended December 31, 2021, 2020 or 2019.

The Company believes that no material amount of the liabilities for uncertain tax positions will expire within 12 months of December 31, 2021.

Semnur is party to an Assignment Agreement with Shah Investor LP, pursuant to which Shah Investor LP assigned certain intellectual property to

Semnur and Semnur agreed to pay Shah Investor LP a contingent quarterly royalty in the low-single digits based on quarterly net sales of any
pharmaceutical formulations for local delivery of steroids by injection developed using such intellectual property, which would include SEMDEXA.
Mahendra Shah, Ph.D., who served on the board of directors of Scilex Holding from March 2019 to October 2020, is the managing partner of Shah
Investor LP.

ordinary course of business with respect to the sale of such Product, and to the extent that they are in accordance with U.S. GAAP. If Scilex Pharma were to
sublicense the licensed technologies, the Developers will receive the same proportion of any sub-licensing fees received therefrom. The Product
Development Agreement will continue in full force and effect until October 2, 2028, the date that is ten years from the date of the first commercial sale of
ZTlido. The Product Development Agreement will renew automatically for subsequent successive one-year renewal periods unless Scilex Pharma or the

14. Segment Information

As of January 1, 2019, the Company realigned its businesses into two operating and reportable segments, Sorrento Therapeutics and Scilex. The

Company reports segment information based on the management approach. The management approach designates the internal reporting used by the Chief
Operating Decision Maker (“CODM”), which is the Company’s Chief Executive Officer, for making decisions and assessing performance as the source of
the Company’s reportable segments. The CODM allocates resources and assesses the performance of each operating segment based on licensing, product
sales and services revenue, operating expenses, and operating income (loss) before interest and taxes. The Company has determined its reportable segments
to be Sorrento Therapeutics and Scilex based on the information used by the CODM.

Sorrento Therapeutics. The Sorrento Therapeutics segment is organized around the Company’s immuno-oncology therapeutic area, leveraging its

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

Scilex. The Scilex segment is largely organized around the Company’s non-opioid pain management operations. Revenues from the Scilex segment

are exclusively derived from the sale of ZTlido.

•

In October 2018, Scilex Pharma commercially launched ZTlido and began recognizing revenue.

Semnur’s SEMDEXATM (SP-102) compound could become the first FDA-approved epidural steroid product for the treatment of sciatica.
SEMDEXATM has been awarded fast track status by the FDA.

Product candidates also include SP-104, 4.5 mg Delayed Burst Release Low Dose Naltrexone Hydrochloride (DBR-LDN) Capsule, for the
treatment of chronic pain, fibromyalgia.

The Company manages its assets on a company basis, not by segments, as many of its assets are shared or commingled. With the exception of
unrestricted cash balances, the Company’s CODM does not regularly review asset information by reportable segment. The majority of long-lived assets for
both segments are located in the United States.

16. Loss Per Share

For the years ended December 31, 2021, 2020, and 2019, basic earnings per share of common stock is computed by dividing net income by the
weighted average number of shares of common stock outstanding during the period. Diluted earnings per share of common stock is calculated to give effect
to all dilutive securities, using the treasury stock method and the if-converted method for potentially dilutive shares of common stock issuable upon the
Semnur Share Exchange, which is described in Note 7.

The following table sets forth the reconciliation of basic and diluted earnings per share for the years ended December 31, 2021, 2020 and 2019 (in

LLC, as lender (the “Lender”), pursuant to which the Company borrowed $45.0 million from the Lender (the “Bridge Loan”). For services rendered in
connection with originating and arranging the Bridge Loan, the Company agreed to pay to B. Riley Securities, Inc., an affiliate of the Lender, an upfront fee
equal to four percent of the principal amount of the Bridge Loan. The Bridge Loan bears no interest and will mature on June 16, 2022. Upon the occurrence
and during the continuance of an “Event of Default” under the Loan Agreement, the Bridge Loan shall bear interest at the rate of 15% per annum. An
“Event of Default” under the Loan Agreement includes, among other things, the Company’s failure to pay any principal of, or interest on, the Bridge Loan
when such principal or interest becomes due and payable or to otherwise perform or observe the terms of the Loan Agreement (subject to cure periods), a
material inaccuracy of the Company’s representation and warranties under the Loan Agreement, a failure by the Company to generally pay its debts as they
become due or a bankruptcy, insolvency or similar event involving the Company.

Exhibit 4.19

The authorized capital stock of Sorrento Therapeutics, Inc., a Delaware corporation (the “Company”), consists of:

DESCRIPTION OF SECURITIES OF SORRENTO THERAPEUTICS, INC.

•

750,000,000 shares of common stock, $0.0001 par value per share (“Common Stock”); and

100,000,000 shares of preferred stock, $0.0001 par value per share (“Preferred Stock”).

Common Stock

Except as otherwise expressly provided in the Company’s Restated Certificate of Incorporation, as amended (the “Certificate of
Incorporation”) or as required by applicable law, all shares of Common Stock have the same rights and privileges and rank
equally, share ratably and are identical in all respects as to all matters, including, without limitation, those described below:

•

Voting rights. Each holder of Common Stock is entitled to one vote per share on each matter that requires stockholder
approval. Holders of Common Stock do not have any cumulative voting rights. There is no provision for cumulative
voting for the election of directors, which means that more than one-half of the shares voted can elect all of the directors
then standing for election. The Company’s Amended and Restated Bylaws (the “Bylaws”) provide that all elections shall
be determined by a plurality of votes cast, and except as otherwise required by law or the rules and regulations of any
stock exchange applicable to the Company, all other matters shall be determined by a majority of votes cast affirmatively
or negatively.

• Dividend rights. The holders of outstanding shares of Common Stock are entitled to receive ratably such dividends, if

any, as may be declared by the Company’s board of directors (the “Board”) out of legally available funds. However, the
current policy of the Board is to retain earnings, if any, for the operations and potential expansion of the business.

•

Liquidation rights. Upon liquidation, dissolution or winding-up, the holders of Common Stock are entitled to share
ratably in all of the Company’s assets which are legally available for distribution, after payment of or provision for all
liabilities.

• No preemptive or similar rights. The holders of Common Stock have no preemptive, subscription, redemption or

conversion rights.

•

Anti-Takeover Provisions. See the below section titled “Anti-Takeover Effects of Provisions of the Company’s
Certificate of Incorporation, Bylaws and the DGCL”.

Listing

The Common Stock is listed on the Nasdaq Capital Market under the symbol “SRNE.”

Preferred Stock

The Certificate of Incorporation provides that the Board may by resolution, without further vote or action by the stockholders,
establish one or more classes or series of Preferred Stock having the number of shares and relative voting rights, designation,
dividend rates, liquidation, and other rights, preferences and limitations as may be fixed by them without further stockholder
approval. Once designated by the Board, each series of Preferred Stock will have specific financial and other terms that will be
set forth in the applicable certificate of designation for the series. Prior to the issuance of shares of each series of Preferred Stock,
the Board is required by the General Corporation Law of the State of Delaware (the “DGCL”) and the Certificate of
Incorporation to adopt resolutions and file a certificate of designation with the Secretary of State of the State of Delaware. The
certificate of designation fixes for each class or series the designations, powers, preferences, rights, qualifications, limitations and
restrictions, including, but not limited to, some or all of the following:

•

The distinctive designation of such series and the number of shares which shall constitute such series, which number
may be increased (except where otherwise provided by the Board in creating such series) or decreased (but not below the
number of shares thereof then outstanding) from time to time by resolution of the Board;

The rate and manner of payment of dividends payable on shares of such series, including the dividend rate, date of
declaration and payment, whether dividends shall be cumulative and the conditions upon which and the date from which
such dividends shall be cumulative;

• Whether shares of such series shall be redeemable, the time or times when, and the price or prices at which, shares of
such series shall be redeemable, the redemption price, the terms and conditions of redemption and the sinking fund
provisions, if any, for the purchase or redemption of such shares;

•

The amount payable on shares of such series and the rights of holders of such shares in the event of any voluntary or
involuntary liquidation, dissolution or winding up of the affairs of the Company;

The rights, if any, of the holders of shares of such series to convert such shares into, or exchange such shares for, shares
of Common Stock, other securities or shares of any other class or series of Preferred Stock and the terms and conditions
of such conversion or exchange;

The voting rights, if any, and whether full or limited, of the shares of such series, which may include no voting rights,
one vote per share or such higher or lower number of votes per share as may be designated by the Board; and

The preemptive or preferential rights, if any, of the holders of shares of such series to subscribe for, purchase, receive or
otherwise acquire any part of any new or additional issue of stock of any class, whether now or hereafter authorized, or
of any bonds,

debentures, notes or any of the Company’s other securities, whether or not convertible into shares of Common Stock.

All shares of Preferred Stock offered hereby will, when issued, be fully paid and nonassessable, including shares of Preferred
Stock issued upon the exercise of preferred stock warrants or subscription rights, if any.

Although the Board has no intention at the present time of doing so, it could authorize the issuance of a series of Preferred Stock
that could, depending on the terms of such series, impede the completion of a merger, tender offer or other takeover attempt.

Warrants

As of December 31, 2021, the Company had outstanding warrants to purchase an aggregate of 16,020,254 shares of Common
Stock as follows:

• warrants to purchase an aggregate of 2,424,242 shares with an exercise price of $2.61 per share, all of which are

currently exercisable and expire on June 21, 2023;

• warrants to purchase an aggregate of 2,663,012 shares with an exercise price of $3.28 per share, all of which are
currently exercisable (subject to certain beneficial ownership limitations) and expire on December 13, 2023;

• warrants to purchase an aggregate of 500,000 shares with an exercise price of $3.28 per share, all of which are currently

exercisable and expire on May 7, 2029;

• warrants to purchase an aggregate of 750,000 shares with an exercise price of $3.94 per share, all of which are currently

exercisable and expire on November 3, 2029;

•

Series A warrants to purchase an aggregate of 6,033,000 shares with an exercise price of $3.75 per share, all of which
are currently exercisable (subject to certain beneficial ownership limitations) and expire on July 2, 2029, all of which
shall be automatically exercised on a “cashless” basis upon expiration in accordance with the terms of the Series A
warrants; and

Series C warrants to purchase an aggregate of 3,650,000 shares with an exercise price of $3.75 per share, all of which are
currently exercisable (subject to certain beneficial ownership limitations) and expire on July 2, 2029, all of which may
be automatically exercised on a “cashless” basis upon expiration in accordance with the terms of the Series C warrants.

All of the outstanding warrants contain provisions for the adjustment of the exercise price in the event of stock dividends, stock
splits or similar transactions. In addition, certain of the warrants contain a “cashless exercise” feature that allows the holders
thereof to exercise the warrants without a cash payment to the Company under certain circumstances. Certain of the warrants also
contain provisions that provide certain rights to warrantholders in the event of a fundamental transaction, including a merger or
consolidation with or into another entity, such as:

•

the right to receive the same amount and kind of consideration paid to the holders of Common Stock in the fundamental
transaction;

the right to require the Company to repurchase the unexercised portion of certain warrants at the warrant’s respective fair
value using the Black Scholes option pricing formula; or

the right to require the Company or a successor entity to redeem the unexercised portion of certain warrants for the same
consideration paid to holders of Common Stock in the fundamental transaction at the warrant’s respective fair value
using the Black Scholes option pricing formula.

Anti-Takeover Effects of Certain Provisions of the Company’s Certificate of Incorporation, Bylaws and General
Corporation Law of the State of Delaware

Certain provisions of the Certificate of Incorporation, the Bylaws and the DGCL may have the effect of discouraging potential
acquisition proposals or tender offers or delaying or preventing a change in control. It is possible that these provisions could
make it more difficult to accomplish or could deter transactions that stockholders may otherwise consider to be in their best
interest or in the Company’s best interests, including attempts by stockholders to replace or remove the Company’s management.

These provisions, summarized below, are expected to discourage coercive takeover practices and inadequate takeover bids. These
provisions are also designed to encourage persons seeking to acquire control of the Company to first negotiate with the Board.
These provisions may delay or prevent someone from acquiring or merging with the Company, which may cause the market price
of the Common Stock to decline.

Blank Check Preferred Stock

The Board is authorized to create and issue from time to time, without stockholder approval, up to an aggregate of 100,000,000
shares of Preferred Stock in one or more series and to establish the number of shares of any series of Preferred Stock and to fix
the designations, powers, preferences and rights of the shares of each series and any qualifications, limitations or restrictions of
the shares of each series.

The authority to designate Preferred Stock may be used to issue a series of Preferred Stock, or rights to acquire Preferred Stock,
that could dilute the interest of, or impair the voting power of, holders of the Common Stock or could also be used as a method of
determining, delaying or preventing a change of control.

Advance Notice Bylaws

The Bylaws contain an advance notice procedure for stockholder proposals to be brought before any meeting of stockholders,
including proposed nominations of persons for election to the Board. Stockholders at any meeting will only be able to consider
proposals or nominations specified in the notice of meeting or brought before the meeting by or at the direction of the Board or
by a stockholder who was a stockholder of record on the record date for the meeting,

who is entitled to vote at the meeting and who has given the Company’s corporate secretary timely written notice, in proper form,
of the stockholder’s intention to bring that business before the meeting. Although the Bylaws do not give the Board the power to
approve or disapprove of stockholder nominations of candidates or proposals regarding other business to be conducted at a
special or annual meeting, the Bylaws may have the effect of precluding the conduct of certain business at a meeting if the proper
procedures are not followed or may discourage or deter a potential acquirer from conducting a solicitation of proxies to elect its
own slate of directors or otherwise attempting to obtain control of the Company.

Choice of Forum

The Bylaws provide that, unless the Board consents to an alternative forum, the Court of Chancery in the State of Delaware will
be the sole and exclusive forum for: (i) any derivative action or proceeding brought by or on behalf of the Company; (ii) any
direct action asserting a claim against the Company or any of its directors or officers pursuant to any of the provisions of the
DGCL, the Certificate of Incorporation or the Bylaws; (iii) any action asserting a claim of breach of fiduciary duties owed by any
of its directors, officers or other employees to its stockholders; or (iv) any action asserting a violation of Delaware decisional law
relating to its internal affairs. This provision does not apply to (a) actions in which the Court of Chancery in the State of
Delaware concludes that an indispensable party is not subject to the jurisdiction of Delaware courts, or (b) actions in which a
federal court has assumed exclusive jurisdiction to a proceeding. This choice of forum provision is not intended to apply to any
actions brought under the Securities Act or the Exchange Act. Section 27 of the Exchange Act creates exclusive federal
jurisdiction over all suits brought to enforce any duty or liability created by the Exchange Act or the rules and regulations
thereunder. As a result, the exclusive forum provision will not apply to suits brought to enforce any duty or liability created by
the Exchange Act or any other claim for which the federal courts have exclusive jurisdiction. However, the Bylaws do not relieve
the Company of its duties to comply with federal securities laws and the rules and regulations thereunder, and its stockholders
will not be deemed to have waived the Company’s compliance with these laws, rules and regulations. The Bylaws also provide
that any person or entity purchasing or otherwise acquiring any interest in shares of capital stock of the Company will be deemed
to have notice of and consented to this choice of forum provision.

This choice of forum provision in the Bylaws may limit a stockholder’s ability to bring a claim in a judicial forum that it finds
favorable for disputes with the Company or its directors, officers or other employees, which may discourage such lawsuits
against the Company and its directors, officers and other employees. In addition, stockholders who do bring a claim in the Court
of Chancery in the State of Delaware could face additional litigation costs in pursuing any such claim, particularly if they do not
reside in or near Delaware. Furthermore, the enforceability of similar choice of forum provisions in other companies’ governing
documents has been challenged in legal proceedings, and it is possible that a court could find these types of provisions to be
inapplicable or unenforceable.

Interested Stockholder Transactions

The Company is subject to Section 203 of the DGCL, which prohibits “business combinations” between a publicly-held
Delaware corporation and an “interested stockholder,” which is

generally defined as a stockholder who is a beneficial owner of 15% or more of a Delaware corporation’s voting stock for a three-
year period following the date that such stockholder became an interested stockholder, unless: (i) the transaction is approved by
the board of directors before the date the interested stockholder attained that status; (ii) upon consummation of the transaction
which resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the voting
stock of the corporation outstanding at the time the transaction commenced; or (iii) on or after the date of the transaction, the
transaction is approved by the board of directors and authorized at a meeting of stockholders, and not by written consent, by the
affirmative vote of at least 66 2/3% of the outstanding voting stock that is not owned by the interested stockholder. In general, the
DGCL defines a business combination to include the following: (a) any merger or consolidation involving the corporation and the
interested stockholder; (b) any sale, transfer, pledge or other disposition of 10% or more of the assets of the corporation involving
the interested stockholder; (c) subject to certain exceptions, any transaction that results in the issuance or transfer by the
corporation of any stock of the corporation to the interested stockholder; (d) any transaction involving the corporation that has the
effect of increasing the proportionate share of the stock of any class or series of the corporation beneficially owned by the
interested stockholder; or (e) the receipt by the interested stockholder of the benefit of any loans, advances, guarantees, pledges
or other financial benefits provided by or through the corporation.

Filling Vacancies

The Certificate of Incorporation provides that the number of directors shall be fixed from time to time exclusively by the Board
pursuant to a resolution adopted by a majority of the total number of authorized directors whether or not there exist any vacancies
in previously authorized directorships. As of December 31, 2021, the Board consists of seven directors.

In the event of a vacancy on the Board, however occurring, including a vacancy resulting from an increase in the size of the
Board, unless otherwise required by law or by resolution of the Board, such vacancy shall be filled only by a majority vote of the
directors then in office, though less than a quorum (and not by stockholders), and directors so chosen shall serve for the
remainder of the full term of the director for which the vacancy was created or occurred or until such director’s successor shall
have been duly elected and qualified. This system of electing and filling vacancies may tend to discourage a third party from
making a tender offer or otherwise attempting to obtain control of the Company, because it generally makes it more difficult for
stockholders to replace a majority of the directors.

Removal of Directors

The Certificate of Incorporation provides for the removal of any of the Company’s directors only for cause and only by the
affirmative vote of the holders of at least 67% of the voting power of all of the then outstanding shares of the Company’s capital
stock then entitled to vote at an election of directors, voting together as a single class. However, in December 2015, the Delaware
Chancery Court issued a decision, In Re VAALCO Energy, Inc., in which the court interpreted Section 141(k) of the DGCL and
held that if a company does not have (i) a classified board of directors or (ii) cumulative voting in election of directors, then such
company may not provide in its certificate of incorporation or bylaws that its directors may be removed only for

cause. Prior to the VAALCO decision, it was not clear whether Section 141(k) prohibits this type of provision when the company
does not have classified board or cumulative vote. The VAALCO decision made it clear that the removal provision in the
Certificate of Incorporation is now invalid. As previously disclosed in a Current Report on Form 8-K filed by the Company on
April 18, 2018, the Board resolved that, until such time as an amendment to the Certificate of Incorporation is approved by the
Company’s stockholders to permit stockholders to remove the Company’s directors with or without cause by a majority of
stockholders, the Company will not enforce the director removal provision of the Certificate of Incorporation to the extent it
purports to limit removal of directors by stockholders only for cause or only by a supermajority of the voting power of all of the
then-outstanding shares of capital stock of the Company.

No Stockholder Action by Written Consent; Special Meetings

The Certificate of Incorporation eliminates the right of stockholders to act by written consent without a meeting and the right to
call a special meeting of stockholders or to require that the Board call a special meeting, except as may be required by statute.

Amendment of Charter Provisions

The amendment of any of the above provisions in the Certificate of Incorporation, except for the provision making it possible for
the Company’s board of directors to issue undesignated Preferred Stock, would require approval by a stockholder vote by the
holders of at least 67% of the voting power of the then outstanding shares of capital stock entitled to vote generally in the election
of directors.

The provisions of the DGCL and the Certificate of Incorporation could have the effect of discouraging others from attempting
hostile takeovers and, as a consequence, they may also inhibit temporary fluctuations in the market price of the Common Stock
that often result from actual or rumored hostile takeover attempts. These provisions may also have the effect of preventing
changes in the Company’s management. It is possible that these provisions could make it more difficult to accomplish
transactions that stockholders may otherwise deem to be in their best interests.
