ITEM 1. BUSINESS

Overview

PART I

We are a commercial-stage, biopharmaceutical company developing a next generation of vaccines to address unmet needs in infectious disease and
immuno-oncology. We are advancing the prevention and treatment of hepatitis B, with the only trivalent hepatitis B vaccine, Sci-B-Vac, which is approved for
use and commercially available in Israel, and recently completed a pivotal Phase III program in the United States, Europe and Canada, and with VBI-2601
(BRII-179),  an  immunotherapeutic  candidate  in  development  in  collaboration  with  Brii  Biosciences  Limited  (“Brii  Bio”)  for  a  functional  cure  for  chronic
hepatitis B. Our enveloped virus-like particle (“eVLP”) platform technology allows for the development of eVLP vaccines that closely mimic the target virus
to  elicit  a  potent  immune  response.  Integrating  our  cytomegalovirus  (“CMV”)  expertise  with  the  eVLP  platform  technology,  our  lead  eVLP  program
candidates include a glioblastoma (“GBM”) vaccine immunotherapeutic candidate, VBI-1901, and a prophylactic CMV vaccine candidate, VBI-1501. We are
headquartered in Cambridge, Massachusetts, with research operations in Ottawa, Canada, and manufacturing operations in Rehovot, Israel.

Sci-B-Vac: Trivalent Prophylactic Hepatitis B Vaccine

Current 
Development Stage

  Phase III Complete

Phase Ib/IIa

Phase I/IIa
Phase I Complete

Sci-B-Vac is a trivalent prophylactic hepatitis B vaccine, which is approved for use and commercially available in Israel, and recently completed its
pivotal Phase III program in the United States, Europe, and Canada. In contrast to other commercially-available hepatitis B vaccines, which contain only one
surface antigen (the S antigen) of hepatitis B, Sci-B-Vac contains all three of the hepatitis B surface antigens: the S antigen, the pre-S1 antigen, and the pre-S2
antigen. Moreover, Sci-B-Vac is distinguished from other commercially-approved hepatitis B vaccines because it is produced in mammalian cells (Chinese
hamster  ovary  “CHO”  cells)  rather  than  in  yeast.  Published  data  demonstrate  that  T  cell  responses  to  the  pre-S1  and  pre-S2  antigens  can  further  boost
responses to the S antigen, resulting in a more immunogenic response.

Sci-B-Vac has not yet been approved for use by the United States Food and Drug Administration (“FDA”), European Medicines Agency (“EMA”) or
Health  Canada.  The  recently  completed  global  Phase  III  clinical  program  was  designed  to  achieve  FDA,  EMA,  and  Health  Canada  market  approvals  for
commercial  sale  of  Sci-B-Vac  in  the  United  States,  Europe,  and  Canada,  respectively.  Our  wholly-owned  subsidiary,  SciVac  Ltd.,  in  Rehovot,  Israel,
manufactures and sells Sci-B-Vac.

On  June  17,  2019,  we  announced  positive  top-line  results  from  the  randomized,  double-blind,  controlled  pivotal  Phase  III  study,  PROTECT,
designed to evaluate the efficacy and safety of a 10µg dose of Sci-B-Vac compared with a 20µg dose of the standard of care vaccine, Engerix-B. The study,
which enrolled a total of 1,607 adults, of which 81% were age ≥ 45 years, met both of its co-primary endpoints: (1) non-inferiority of seroprotection rate
(“SPR”) of Sci-B-Vac (91.4%) vs. Engerix-B (76.5%) in all subjects age ≥ 18 years, 4 weeks after 3rd vaccination (SPR difference: 14.9%; 95% confidence
interval  (“CI”)  [11.2%,  18.5%]);  and  (2)  superiority  of  SPR  of  Sci-B-Vac  (89.4%)  vs.  Engerix-B  (73.1%)  in  subjects  age  ≥  45  years,  4  weeks  after  3rd
vaccination  (SPR  difference:  16.4%;  95%  CI  [12.2%,  20.7%]).  Moreover,  the  SPR  of  Sci-B-Vac  compared  to  Engerix-B  was  higher  in  all  key  subgroup
analyses of adults age ≥ 18 years, including by age, gender, body mass index (“BMI”), diabetic status, and smoking status, four weeks after 3rd vaccination.

On  January  9,  2020  we  reported  positive  top-line  results  from  CONSTANT,  the  second  pivotal  Phase  III  study,  designed  to  assess  lot-to-lot
manufacturing consistency of Sci-B-Vac, and compare the safety and immunogenicity of Sci-B-Vac to Engerix-B. The CONSTANT Phase III study, which
enrolled  2,838  adults,  age  18-45  years,  met  both  the  primary  and  secondary  endpoints.  The  primary  endpoint  of  CONSTANT  study  was  directed  to  the
manufacturing  consistency  of  Sci-B-Vac.  For  this  primary  endpoint,  the  study  evaluated  the  vaccine  immune  response,  as  measured  by  geometric  mean
concentration  (“GMC”)  of  antibodies  across  three  independent,  consecutively-manufactured  lots  of  Sci-B-Vac,  four  weeks  after  the  third  vaccination.
Together with the positive safety and immunogenicity results of the PROTECT Phase III study, we expect these data to comprise the basis for the regulatory
submissions in the United States, Europe, and Canada.

A secondary endpoint of the CONSTANT study demonstrated non-inferiority of SPR of Sci-B-Vac (99.3%) vs. Engerix-B (94.8%), one month after
completion of the full course of vaccination (SPR difference: 4.49%; 95% CI [2.90%, 6.63%] – up from 90.4% for Sci-B-Vac and 51.6% for Engerix-B at day
168, after only two vaccinations. In addition to demonstrating non-inferiority, the SPR achieved with Sci-B-Vac compared to Engerix-B was higher after both
two  and  three  vaccinations.  An  exploratory  analysis  in  CONSTANT  also  compared  the  SPR  after  two  doses  of  Sci-B-Vac  (90.4%)  to  the  SPR  after  three
doses of Engerix-B (94.8%) (SPR difference: -4.3%; 95% CI [-6.48%, -1.90%]). As per the commonly-used statistical margin of non-inferiority for hepatitis
B vaccines, defined as the lower limit of the 95% CI being above -10%, this analysis demonstrated non-inferiority after two doses of Sci-B-Vac (at day 168)
compared with three doses of Engerix-B (at day 196). Similarly, at these time points, preliminary data from the integrated immunogenicity analysis of both
the PROTECT and CONSTANT studies in subjects age 18-45 years demonstrate a difference in SPR of -4.2%; 95% CI [-6.38%, -1.99%]. The two versus
three  dose  comparison  is  not  part  of  the  regulatory  approval  process  and  will  not  be  included  in  the  expected  indication  we  will  seek,  but  we  believe  it
contributes to the robust immunogenicity profile of Sci-B-Vac.

The safety and tolerability seen in CONSTANT and PROTECT studies were consistent with the known safety profile of Sci-B-Vac. No new safety
risks  were  identified,  and  no  safety  signals  were  observed  in  either  study  cohort.  The  integrated  safety  data  analysis  from  both  the  PROTECT  and
CONSTANT studies is underway.

The  completed  Phase  III  studies  are  expected  to  support  the  Biologics  License  Application  (“BLA”)  to  the  FDA,  the  Marketing  Authorization
Application (“MAA”) to the EMA and the New Drug Submission (“NDS”) to Health Canada. We plan to submit applications for regulatory approvals in the
United States, Europe and Canada beginning in the fourth quarter of 2020.

VBI-2601: Hepatitis B Immunotherapeutic Candidate

VBI-2601 (BRII-179) is our novel, recombinant, protein-based immunotherapeutic candidate in development for the treatment of chronic hepatitis B
infection, a disease that affects more than 250 million people worldwide. Chronic hepatitis B infection can lead to cirrhosis of the liver, hepatocellular cancer,
and other liver disease, making it a life-threatening global health problem. VBI-2601 (BRII-179) is formulated to induce broad immunity against the hepatitis
B virus, including T-cell immunity which plays an important role in controlling hepatitis B infection.

On December 6, 2018, the Company announced that it had entered into a Collaboration and License Agreement (“License Agreement”) with Brii
Bio, pursuant to which, among other things, subject to terms and conditions set forth in the License Agreement, we and Brii Bio agreed to collaborate on the
development of a hepatitis B recombinant protein-based immunotherapeutic candidate in China, Hong Kong, Taiwan and Macau (the “Licensed Territory”),
and to conduct a Phase Ib/IIa collaboration clinical trial for the purpose of comparing VBI-2601 (BRII-179) with a novel composition developed jointly with
Brii Bio.

On November 14, 2019 we announced initiation of enrollment in a Phase Ib/IIa Study of VBI-2601 (BRII-179) in patients with chronic hepatitis B
infection. The Phase Ib/IIa clinical study of VBI-2601 (BRII-179) is a randomized, controlled study designed to assess the safety, tolerability, antiviral, and
immunological  activity  of  VBI-2601  (BRII-179).  The  study  is  designed  as  a  two-part  dose-escalation  study  assessing  different  dose  levels  of  VBI-2601
(BRII-179)  with  and  without  an  immunomodulatory  adjuvant,  and  is  expected  to  enroll  up  to  65  patients.  Initial  human  proof-of-concept  data  from  the
clinical study is anticipated in the second half of 2020. The study is sponsored by Brii Bio and will be conducted at multiple study sites in New Zealand,
Australia, Thailand, South Korea, Hong Kong SAR, and China.

eVLP Platform

The eVLP technology enables the synthetic manufacture of an “enveloped” virus-like particle, or “eVLP”. Many viruses are “enveloped” in that they
are  surrounded  by  a  lipid  bilayer  membrane.  Such  viruses  display  antigenic  proteins  on  the  surface  of  their  “envelope”  which  can  be  targets  for  vaccine
development. The ability to synthetically manufacture an “enveloped” virus-like particle is different from previously developed VLP technologies, which did
not include the lipid bilayer membrane, and thus these technologies were unable to express antigenic proteins within an “envelope” as they occur in nature.

VBI-1901: Cancer Vaccine Immunotherapeutic Candidate

Our GBM brain cancer vaccine immunotherapeutic program, VBI-1901, targets CMV proteins present in GBM tumor cells. CMV is associated with
a number of other solid tumors in addition to GBM, including breast cancer and pediatric medulloblastoma. We initiated dosing in a multi-center Phase I/IIa
clinical study evaluating VBI-1901, in combination with granulocyte-macrophage colony stimulating factor (“GM-CSF”), in patients with recurrent GBM in
January 2018. Enrollment in Part A of the study was completed in December 2018. In April 2019, the independent data safety monitoring board completed
reviews of all safety data from our fully-enrolled Part A portion of the Phase I/IIa trial in recurrent GBM subjects, which included 6 subjects in each of 3
different dose cohorts. The data safety monitoring board unanimously recommended the continuation of the study without modification and had no safety
concerns about any of the 3 dose levels of VBI-1901. On April 23, 2019, we announced that, based on safety and immunogenicity data, the highest dose
tested in Part A of the ongoing Phase I/IIa study in recurrent GBM patients, 10µg, was selected as the optimal dose level to test in Part B of the study. Where
Part  A  was  designed  as  a  dose-escalation  phase  to  assess  safety,  tolerability,  and  to  define  the  optimal  dose  level  of  VBI-1901,  Part  B  is  a  subsequent
extension phase of the optimal dose level defined in Part A.

On September 10, 2019, we entered into a Clinical Collaboration Agreement (“Collaboration Agreement”) with GlaxoSmithKline Biologicals S.A.
(“GSK”) pursuant to which we will investigate the use of GSK’s proprietary AS01B adjuvant system in our ongoing study of VBI-1901. As a result of the
Collaboration  Agreement,  a  second  study  arm  was  added  to  Part  B  of  the  ongoing  Phase  I/IIa  clinical  study.  Part  B  is  now  a  two-arm  open-label  study,
enrolling 20 first recurrent GBM patients to receive VBI-1901 in combination with either granulocyte-macrophage colony-stimulating factor (“GM-CSF”) or
AS01B as immunomodulatory adjuvants. Enrollment of the 10 patients in the VBI-1901 with GM-CSF arm was initiated at the end of July 2019. Initiation of
enrollment of the 10 patients in the VBI-1901 with AS01B was announced in March 2020.

Safety, immunologic responses, and clinical and tumor responses from the VBI-1901 with GM-CSF in Part A and in the GM-CSF arm of Part B of
the  study  were  announced  throughout  2019  and  early  2020,  respectively.  VBI-1901  continues  to  be  well-tolerated,  with  no  vaccine-related  safety  signals
observed. In the high-dose cohort of Part A, vaccine response correlated with tumor response, with all three vaccine responders demonstrating stable disease
(“SD”) for greater than 12 weeks. Two patients in the high-dose cohort of Part A experienced a 60% reduction in the size of primary tumor. VBI-1901 also
induced and expanded robust T cell responses in these two patients. For patients who were vaccines responders, the 12-month overall survival (“OS”) rate
was 83% (n = 5/6), compared to 33% (n = 3/9) for vaccine non-responders. Similarly, among patients evaluable for response and survival in Part A, vaccine
responders saw a 6.25-month improvement in median OS (14.0 months) compared to vaccine non-responders (7.75 months). VBI-1901 continues to be safe
and well tolerated at al doses tested, with no safety signals observed.

Based on the data announced in November 2019, the early tumor and immunologic responses seen in Part B appear similar to the responses observed
in Part A of the study. Correlations between immunologic biomarkers and tumor/clinical responses will continue to be refined throughout the duration of Part
B of the study.

We expect expanded immunologic data and tumor imaging data from the VBI-1901 with GM-CSF arm in Part B of the study in the first half of

2020.

VBI-1501: Prophylactic CMV Vaccine Candidate

Another of our eVLP programs is a vaccine candidate that aims to prevent CMV infections. CMV may cause severe infections in newborn children
(congenital CMV) and may also cause serious infections in people with weakened immune systems, such as solid organ or bone marrow transplant recipients.
Our prophylactic CMV vaccine candidate uses the eVLP platform to express a modified form of the CMV glycoprotein B (“gB”) antigen and is adjuvanted
with alum, an adjuvant used in FDA-approved products.

In May 2018, we announced positive top-line results from the randomized, placebo-controlled Phase I study of VBI-1501. The final Phase I study
results demonstrated that VBI-1501 was safe and well-tolerated at all doses, with and without the adjuvant alum. The highest dose of VBI-1501, 2.0µg, with
alum, elicited CMV-neutralizing antibodies against fibroblast cell infection in 100% of subjects after the third vaccination, up from 81% of subjects after the
second  vaccination,  inducing  titers  comparable  to  those  observed  in  patients  protected  as  a  result  of  natural  infection.  Neutralizing  antibodies  against
epithelial cell infection were also seen in 31% of subjects after the third vaccination of VBI-1501 2.0µg with alum. The data also showed the formulation of
the vaccine with alum enhanced antibody titers. The highest dose of VBI-1501 tested, 2.0µg with alum, contains approximately 10-fold less antigen content
than that used in several other VLP-based vaccines or in previous CMV vaccine candidates developed by other companies.

On December 20, 2018 we announced plans for a Phase II clinical study evaluating VBI-1501 following positive discussions with Health Canada. We
received similarly positive guidance from the FDA in July 2019. The Phase II study is expected to assess the safety and immunogenicity of dosages of VBI-
1501 up to 20µg with alum. The Company is currently evaluating the timing of next steps for the program.

We may also seek to in-license clinical-stage vaccines or vaccine-related technologies that we believe complement our product and pipeline portfolio,

in addition to technologies that may supplement our therapeutic vaccination efforts in immuno-oncology.

Recent Corporate Developments

Modernization and Capacity Increase of our Manufacturing Facility

In 2018, we temporarily closed our manufacturing facility in Rehovot, Israel, for modernization and capacity increase. We re-commenced operations
in May 2019 and the review of the modernization and the capacity increase by the Israeli Ministry of Health (“IMoH”) occurred in December of 2019. We
received  our  certificate  of  Good  Manufacturing  Practice  (“GMP”)  compliance  from  the  IMoH  on  January  27,  2020.  In  addition  to  the  GMP  compliance
certification, the IMoH will also need to review and approve the process validation submission and provide approval for us to sell Sci-B-Vac manufactured at
the modernized facility. We increased the capacity of our manufacturing facility to be able to supply commercial quantities of Sci-B-Vac upon FDA, and/or
EMA and/or Health Canada approval, as well as supply the clinical materials of VBI-2601 (BRII-179).

Equity Financing Activities

In  September  2019,  we  received  aggregate  gross  proceeds  of  $40.25  million  from  an  underwritten  public  offering  of  an  aggregate  of  80,500,000
common  shares  at  a  price  of  $0.50  per  share.  After  deducting  the  underwriting  discounts  and  commissions  and  offering  expenses,  net  proceeds  from  the
offering were $37.4 million. Net proceeds from the offering are being used to support our pipeline programs, to continue the advancement of our clinical
development and research programs and for other general corporate purposes.

NASDAQ Minimum Bid Price Requirement

As  previously  reported,  on  August  14,  2019,  we  received  a  letter  from  the  Listing  Qualifications  Department  of  the  Nasdaq  Stock  Market
(“NASDAQ”)  indicating  that,  based  upon  the  closing  bid  price  of  our  common  shares  for  the  30  consecutive  business  day  period  between  July  2,  2019
through August 13, 2019, we did not meet the minimum bid price of $1.00 per share required for continued listing on The NASDAQ Capital Market pursuant
to NASDAQ Listing Rule 5550(a)(2). The letter also indicated that we would be provided with a compliance period of 180 calendar days, or until February
10, 2020 (the “Compliance Period”), in which to regain compliance pursuant to NASDAQ Listing Rule 5810(c)(3)(A). In order to regain compliance with
NASDAQ’s  minimum  bid  price  requirement,  our  common  shares  needed  to  maintain  a  minimum  closing  bid  price  of  $1.00  for  at  least  ten  consecutive
business  days  during  the  Compliance  Period.  On  January  9,  2020  we  received  notice  from  the  NASDAQ  indicating  that  the  Company  has  regained
compliance with the minimum bid price requirement under Nasdaq Listing Rule 5550(a)(2), and the matter is now closed.

Corporate History

We  were  incorporated  under  the  laws  of  British  Columbia  by  Memorandum  of  Association  on  April  9,  1965  under  the  name  “Alice  Arm
Molybendum Co. Ltd.” On October 21, 1965, we changed our name to “Alice Arm Mining Ltd.” and subsequently, on July 13, 1975, changed our name to
“New Congress Resources Ltd.” On January 12, 1983, we changed our name to “Levon Resources Ltd.”

On July 9, 2015, we, then known as Levon Resources Ltd. (“Levon”), completed a plan of arrangement (the “Levon Merger”) pursuant to which
SciVac Ltd. (“SciVac”), an Israel based company, completed a reverse takeover of Levon. Levon changed its name from Levon Resources Ltd. to SciVac
Therapeutics Inc. and SciVac became our wholly-owned subsidiary.

On May 6, 2016, we completed our acquisition of VBI Vaccines (Delaware) Inc. (“VBI DE”), pursuant to which Seniccav Acquisition Corporation,
a Delaware corporation and our wholly-owned subsidiary, merged with and into VBI DE, with VBI DE continuing as the surviving corporation and as our
wholly-owned subsidiary (the “VBI-SciVac Merger”). Upon completion of the VBI-SciVac Merger, we (then named “SciVac Therapeutics Inc.”) changed our
name to “VBI Vaccines Inc.” and received approval for the listing of our common shares on the NASDAQ Capital Market. Our common shares commenced
trading on the NASDAQ Capital Market at the opening of trading on May 9, 2016 under our new name and the symbol “VBIV.” Following the effective time
of the VBI-SciVac Merger, our common shares began to trade on the TSX under the new symbol “VBV.” Effective as of March 23, 2018, we voluntarily
delisted our common shares from the TSX.

Our registered office is located at Suite 1700, Park Place, 666 Burrard Street, Vancouver British Columbia V6C 2X8. Our principal executive offices
are located at 222 Third St. Suite 2241, Cambridge, MA 02142. Our manufacturing operations are located at 13 Gad Feinstein Road, POB 580, Rehovot,
Israel 7610303 and our research operations are located at 310 Hunt Club Road East, Suite 201, Ottawa, Ontario Canada K1V 1C1.

Background of VBI DE

VBI DE was originally established in 1970 as Paulson Capital Corp., an Oregon corporation (“Paulson Oregon”), which began as a holding company
whose operating subsidiary, Paulson Investment Company, Inc., was a full-service brokerage firm. Effective March 20, 2014, Paulson Oregon changed its
state of incorporation from the State of Oregon to the State of Delaware, and as a result, Paulson Oregon became “Paulson Capital (Delaware) Corp.” and
Paulson Oregon ceased to exist.

On July 25, 2014, Variation Biotechnologies (US), Inc. (“VBI US”) completed its merger with VBI Acquisition Corp. (“Merger Sub”), a Delaware
corporation and wholly-owned subsidiary of Paulson Capital (Delaware) Corp., whereby Merger Sub merged with and into VBI US, with VBI US continuing
as  the  surviving  corporation.  As  a  result  of  this  merger,  VBI  US  was  acquired  by,  and  became  a  wholly-owned  subsidiary  of  Paulson  Capital  (Delaware)
Corp., which changed its name to VBI Vaccines Inc. and then subsequently to VBI Vaccines (Delaware) Inc. on July 19, 2016.

Pursuant to the License Agreement and the initial development plan, Brii Bio shall fund all clinical trials for the Licensed Territory. We and Brii Bio
will  jointly  own  all  right,  title  and  interest  in  the  joint  know-how  development  and  the  patents  claiming  joint  inventions  made  pursuant  to  the  License
Agreement.

As part of the consideration for the collaboration, we received from Brii Bio a total upfront payment of $11 million. We are also eligible to receive
an additional $117.5 million in potential milestone payments, along with potential low double-digit royalties on commercial sales in the Licensed Territory. In
connection with the License Agreement, we and Brii Bio entered into a stock purchase agreement, dated as of December 4, 2018, pursuant to which we issued
to  Brii  Bio  an  aggregate  of  2,295,082  common  shares  in  exchange  for  a  gross  contractual  allocation  of  $7  million  (included  in  the  $11  million  upfront
payment), or $3.05 per share, which had a fair value of $3.6 million on the date of issuance.

The  License  Agreement  will  be  in  effect  until  the  last-to-expire  of  the  latest  of  the  following  terms  in  each  region  of  the  Licensed  Territory:  (i)
expiration,  invalidation  or  lapse  of  the  last  of  our  patent  claiming  a  Licensed  Product,  (ii)  10  years  from  the  date  of  first  commercial  sale  of  a  Licensed
Product in the applicable region, or (iii) termination or expiration of our obligation to pay third party royalties with respect to sales of a Licensed Product.
Upon expiration (but not an earlier termination) of the License Agreement in each region of the Licensed Territory, we will grant Brii Bio a perpetual, non-
exclusive, fully paid-up, royalty free license under our technology related to the licensed compounds or Licensed Products pursuant to the License Agreement
in  such  region  to  make  and  sell  Licensed  Products  for  the  diagnosis  and  treatment  of  hepatitis  B  in  such  region.  Each  party  may  terminate  the  License
Agreement upon a material breach of the License Agreement which has not been cured within 60 days (or 30 days for a breach payment obligations) after
notice from the terminating party requesting cure of the breach, or upon bankruptcy or insolvency, either voluntary or involuntary, dissolution or liquidation
of a party. In addition, Brii Bio may terminate the License Agreement without cause upon 180 days’ notice or, if the Data and Safety Monitoring Board or any
regulatory authority in the Licensed Territory imposes a clinical hold on any clinical trial for a Licensed Product for six consecutive months, immediately
upon notice. We may terminate the License Agreement immediately upon notice, if Brii Bio or its affiliates, directly, or indirectly through any third party,
commences any interference or opposition proceeding with respect to, challenges the validity or enforceability of, or opposes any extension of or the grant of
a supplementary protection certificate with respect to, any patents owned or controlled by us related to the composition or the method of making or using
licensed  compounds  or  Licensed  Products,  or  are  otherwise  necessary  or  useful  to  research,  develop,  make,  or  otherwise  commercialize  the  licensed
compounds or Licensed Products.

Prior to us entering into the License Agreement, we paid $6 million to terminate a distribution agreement with a third party who previously held

certain distribution rights to certain Asian markets.

Ferring and SciGen License Agreements

Our  manufactured  and  marketed  product,  Sci-B-Vac  is  a  trivalent  hepatitis  B  vaccine  which  is  the  subject  of  a  license  agreement  with  Savient
Pharmaceuticals Inc. and SciGen Ltd dated June 2004, as subsequently amended (the “Ferring License Agreement”). Under the Ferring License Agreement,
we  are  committed  to  pay  Ferring  royalties  equal  to  7%  of  net  sales  (as  defined  therein)  of  HbsAg  “Product”  (as  defined  therein).  Under  an  Assignment
Agreement between FDS Pharm LLP and SciGen Ltd., dated February 14, 2012 (the “SciGen Assignment Agreement”), we are required to pay royalties to
SciGen  Ltd.  equal  to  5%  of  net  sales  (as  defined  in  the  Ferring  License  Agreement)  of  Product.  Under  the  Ferring  License  Agreement  and  the  SciGen
Assignment Agreement, we originally were to pay royalties on a country-by-country basis until the date 10 years after the date of commencement of the first
royalty year in respect of such country. In April 2019, we exercised our option to extend the Ferring License Agreement in respect of all the countries that still
make up the territory for an additional 7 years by making a one-time payment to Ferring of $100. Royalties under the Ferring License Agreement and SciGen
Assignment Agreement will continue to be payable for the duration of the extended license periods.

Royalty payments under the Ferring License Agreement of $38 and $42, were recorded in cost of revenues for the year ended December 31, 2019

and 2018, respectively.

Royalty payments under the SciGen Assignment Agreement of $27 and $30 were recorded in cost of revenues for the year ended December 31, 2019

and 2018, respectively.

In  addition,  we  are  committed  to  pay  30%  of  any  and  all  non-royalty  consideration,  in  any  form,  received  by  us  from  sub-licensees  (other  than
consideration based on net sales for which a royalty is due under the Ferring License Agreement), provided that the payment of 30% shall not apply to a grant
of rights in or relating to: (i) the Territory (as such term was defined prior to an amendment dated January 24, 2005); or (ii) the Berna Territory (as defined
therein).

eVLP Technology

We  are  engaged  in  the  inbound  licensing  of  key  intellectual  property  (“IP”).  We  identified  the  need  for  a  vaccine  antigen  discovery  and  design
platform  and,  through  that  certain  sale  and  purchase  agreement  entered  into  on  July  18,  2011  (the  “Sale  and  Purchase  Agreement”)  among  VBI  Cda  and
ePixis SA (“ePixis”) and the shareholders of ePixis (collectively, the “Sellers”), acquired 100% of the outstanding shares of ePixis in order to obtain access to
its exclusive rights to key IP covering its “enveloped Virus Like Particle” or “eVLP” vaccine platform (the “Technology”), including patents (the “Acquired
Patents”) covering the Technology. We paid a purchase price of €400 (approximately $450) for the ePixis shares and approximately $75 in related transaction
costs. VBI Cda also agreed to make certain contingent payments to the Sellers as follows:

● Upon the earlier to occur of (i) first approval by the FDA of a new drug application (an “NDA”) permitting us or any sublicensee to market and sell
any pharmaceutical product or candidate pharmaceutical product that contains or can express an eVLP (a “eVLP Product”) in the United States or
(ii) first approval by the EMA of a Marketing Authorization Application or equivalent submission permitting us or our sublicensees to market and
sell a eVLP Product candidate in one or more countries in the EU, we must pay to the Sellers €1,000, or, if there are no longer any issued and valid
claims of the Acquired Patents in effect at the date such event occurs, €500.

If a eVLP Product is commercialized, we will be required to pay the Sellers the following:

● On the date that Cumulative Net Sales (as defined in the Sale and Purchase Agreement), of all eVLP Products equals or exceeds €25,000, we must
pay to the Sellers €1,500, or, if there are no longer any issued and valid claims of the Acquired Patents in effect at the date such event occurs, €750;
and

● On the Date that Cumulative Net Sales of all eVLP Products equals or exceeds €50,000 in the aggregate, we must pay to the Sellers €2,000 or, if

there are no longer any issued and valid claims of the Acquired Patents in effect at the date such event occurs, €1,000.

8

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
If any eVLP Product is commercialized by one or more sublicensees, we have agreed to make the following payments to the Sellers:

● On the date that Cumulative Net Sales by us or any sublicensees of the eVLP Products equal or exceed €25,000 in the aggregate, we must pay to the

Sellers €750, or, if there are no longer any issued and valid claims of the Acquired Patents in effect at the date such event occurs, €375;

● On the date that Cumulative Net Sales made by us or any sublicensees of the eVLP Products equal or exceed €50,000 in the aggregate, we must pay

to the Sellers €750, or, if there are no longer any issued and valid claims of the Acquired Patents in effect at the date such event occurs, €375;

● On the date that Cumulative Net Sales made by us or any sublicensees of the eVLP Products equal or exceed €75,000 in the aggregate, we must pay

to the Sellers €1,000, or, if there are no longer any issued and valid claims of the Acquired Patents in effect at the date such event occurs, €500; and

● On the date that Cumulative Net Sales made by us or any sublicensees of the eVLP Products equal or exceed €100,000 in the aggregate, we must pay
to the Sellers €1,000, or, if there are no longer any issued and valid claims of the Acquired Patents in effect at the date such event occurs, €500.

Included  in  the  eVLP  Acquired  Patents  were  patents  (the  “UPMC  Patents”)  co-owned  by  L’Universite  Pierre  et  Marie  Curie  (“UPMC”),  and  the
Institut  National  de  la  Santé  et  de  la  Recherche  Médicale  (“INSERM”),  both  in  Paris,  France.  In  July  2006,  ePixis  entered  into  a  license  agreement  (the
“ePixis License Agreement”) with UPMC, INSERM and L’école Normale Supérieure de Lyon (collectively the “Licensor”) pursuant to which the Licensor
granted  to  ePixis  an  exclusive  license  (with  the  right  to  sublicense  with  written  consent  from  UPMC)  to  exploit  the  UPMC  Patents  for  the  purpose  of
developing, promoting and marketing products within the United States, Japan, Canada, and Europe until the invalidation of the last of the UPMC Patents,
including any supplementary protection certificates. Pursuant to the ePixis License Agreement, ePixis was to pay certain fees to the Licensor based on net
sales (as defined in the ePixis License Agreement) of products developed from the UPMC Patents, sublicensing income based on net sales (“Sublicensing
Payments”) and one-time payments (“Lump Sum Payments”) for each product developed from the UPMC Patents. ePixis also agreed to reimburse UPMC for
fees and costs related to filing and maintaining the patent applications.

On  July  12,  2011,  the  parties  to  the  ePixis  License  Agreement  entered  into  the  first  amendment  to  the  ePixis  License  Agreement  (the  “ePixis
Amendment”). The ePixis Amendment authorized the transfer of the ePixis License Agreement to us and laid out new financial terms and conditions for the
rights granted under the ePixis License Agreement.

The ePixis Amendment provides that the fees to be paid to the Licensor by ePixis on net sales of eVLP Products based on the UPMC Patents will be
1.75% of net sales for annual sales between €0 and €50,000, 1% of net sales for annual sales between €50,000 and €100,000, and 0.75% of net sales for
annual sales in excess of €100,000. Pursuant to the ePixis Amendment, Lump Sum Payments would be made as follows:

● €50 when the results from pre-clinical studies are sufficient to allow a product to enter a regulatory filing similar to an IND or a similar entity in a
country other than the United States; this milestone was met and paid during the year ended December 31, 2016 for the CMV candidate and during
the year ended December 31, 2018 for the GBM candidate;

● €150 when  the  results  from  pre-clinical  studies  are  sufficient  to  allow  a  product  into  a  clinical  phase,  including  Phase  I-II  clinical  studies;  this
milestone was met and paid during the year ended December 31, 2016 for the CMV candidate and during the year ended December 31, 2018 for the
GBM candidate;

● €250 when a product enters Phase II clinical studies, an event that is defined by the enrollment of the first patient;

● €500 when a product enters Phase III clinical studies; and

● €1,000 when a product is first marketed.

Sublicensing  Payments  under  the  ePixis  Amendment  were  revised  as  follows:  25%  of  any  amounts  received  by  ePixis  for  the  sublicense  if  the
sublicense is entered into prior to the start of Phase I clinical studies; 10% of any amounts received by ePixis if the sublicense is entered into during Phase I
clinical studies and prior to the start of Phase II clinical studies; 7% of any amounts received by ePixis if the sublicense is entered into during Phase II clinical
studies and prior to the start of Phase III clinical studies, and 5% of any amounts received by ePixis if the sublicense is entered into after the start of Phase III
clinical  studies.  There  was  no  change  to  the  requirement  that  ePixis  reimburse  UPMC  for  fees  and  costs  related  to  filing  and  maintaining  the  patent
applications.

The parties may terminate the ePixis License Agreement, as amended, by mutual agreement. There is also a cancellation right that may be exercised
in the event of breach. UPMC may terminate the ePixis License Agreement if we, among other things, declare bankruptcy; do not put forth reasonable effort
or are unable to develop and market the products, and, in particular, if we suspend the development of the products for more than six months; our inability to
make the payments required by the ePixis License Agreement; lack of sales of a product, or lack of a signed sub-license agreement within one year from the
date of acquiring AMM (Autorisation de mise sur le marché – Regulation of Therapeutic Goods) authorization, or the necessary equivalent authorization for
the use of the products; and lack of sales of a product for more than two years after the initial marketing has taken place. During the year-ended December 31,
2016, VBI Cda paid UPMC €200, in milestone payments related to CMV Phase I clinical trial approval and start. Payments made to UPMC were €0 during
the year ended December 31, 2019 and €200 during the year ended December 31, 2018.

Description of Operations

We are headquartered in Cambridge, Massachusetts, with our manufacturing facility in Rehovot, Israel and our research facility in Ottawa, Ontario,
Canada. The Cambridge headquarters allows us to leverage our location in a biotechnology hub, and provides us with access to experienced consultants and
executive level talent.

We operate a proprietary, mammalian cell-derived vaccine manufacturing facility in Rehovot, Israel, which we use to manufacture Sci-B-Vac. The
facility  was  built  in  December  2006  and  was  GMP  certified  by  the  IMoH.  It  has  also  received  IMoH  authorization  to  release  vaccine  batches  to  export
markets.  In  2013,  the  EU  entered  into  an  agreement  with  Israel  regarding  conformity  assessment  and  acceptance  of  industrial  products.  This  agreement
recognizes  Israel’s  industrial  standards  as  being  equivalent  to  EU  standards.  It  covers  products  for  human  and  veterinary  use  (medicinal  products,  active
pharmaceutical  ingredients  and  excipients)  and  procedures  related  to  GMP.  The  agreement  means  that  Israel  and  the  EU  recognize  each  other’s  GMP
inspection  conclusions,  manufacturing  and  import  authorizations  and  certification  of  conformity  of  batches;  however,  our  facility  will  have  to  pass  FDA
inspection  as  part  of  the  BLA  application  process  for  Sci-B-Vac  in  the  United  States.  In  2018,  we  temporarily  closed  our  manufacturing  facility  for
modernization and capacity increase. We re-commenced operations in May 2019 and we received a certificate of GMP compliance from the IMoH on January
27, 2020. In addition to the GMP compliance certification, the IMoH will also need to review and approve the process validation submission and provide
approval  for  us  to  sell  Sci-B-Vac  manufactured  at  the  modernized  facility.  We  increased  the  capacity  of  our  manufacturing  facility  to  be  able  to  supply
commercial quantities of Sci-B-Vac upon FDA, EMA and/or Health Canada approval as well as supply clinical materials of VBI-2601 (BRII-179).

10

 
 
 
 
 
 
 
The Canadian research site benefits from its location in Canada’s National Capital Region, providing us with access to world-class research facilities at
reasonable rates. This helps keep the unit cost of doing research lower compared to other locations in Canada or the United States. VBI Cda’s active research
collaboration with the Canadian federal government’s National Research Council (“NRC”) provides its staff with on-site access to the NRC’s animal facility
for greater control over the testing of our pipeline candidates. NRC staff manages the general animal husbandry and maintenance requirements for VBI Cda’s
animal research activities.

The three sites collaborate efficiently through the use of a unified information technology infrastructure and web-based video-conferencing services.

Sales and Marketing

We maintain a business development function responsible for inbound and outbound licensing of our IP portfolio. We do not have a traditional sales
and marketing function and distribute Sci-B-Vac through a network of distributors. We have an active named-patient program to supply Sci-B-Vac to patients
in a few countries where Sci-B-Vac has not yet been approved via partnership with local distributors. Additionally, internal work is underway to prepare for
the potential commercial launch of Sci-B-Vac in the United States, Europe, and Canada subject to receiving the applicable regulatory approvals.

Customers

Our customers for Sci-B-Vac vaccines are mainly physicians and pharmacists in markets where the product is approved. Through SciVac, services are
also made available to the biotechnology industry in Israel pursuant to an agreement with the Israel Innovations Authority (formerly the Office of the Chief
Scientist in Israel) and ancillary to the core vaccine development and manufacturing focus.

In addition to direct sales of Sci-B-Vac in approved territories, we are also engaged in the development of vaccine platforms and products which may

be licensed to major pharmaceutical companies and larger biotechnology companies.

Competitors

Our  products  and  pipeline  candidates  face,  and  will  continue  to  face,  intense  competition  from  large  pharmaceutical  companies,  specialty
pharmaceutical  and  biotechnology  companies  as  well  as  academic  and  research  institutions.  We  compete  in  an  industry  that  is  characterized  by:  rapid
technological  change;  evolving  industry  standards;  emerging  competition;  and  new  product  introductions.  Competitors  have  existing  products  and
technologies that will compete with our pipeline candidates and technologies and may develop and commercialize additional products and technologies that
will compete with our pipeline candidates and technologies. Because several competing companies and institutions may have greater financial resources than
us, they may be able to: provide broader services and product lines; make greater investments in research and development (“R&D”); and carry on larger
R&D initiatives. Competitors may also have greater development capabilities than we do and have substantially greater experience in undertaking nonclinical
and clinical testing of products, obtaining regulatory approvals and manufacturing and marketing pharmaceutical products. They may also have greater name
recognition and better access to customers.

We  face  general  market  competition  from  several  subsectors  of  the  vaccine  development  field,  including:  large,  multinational  pharmaceutical
companies including Sanofi S.A., GSK, Merck & Co (“Merck”), Janssen Pharmaceutical, Inc (“Janssen”), Mitsubishi Tanabe Pharma Corporation, Takeda
Pharmaceutical  Company  Limited  and  Pfizer,  Inc.;  mid-size  pharmaceutical  companies  and  emerging  biotechnology  companies  including  Dynavax
Technologies Corporation (“Dynavax”), Moderna, Inc., Hookipa Biotech AG; and academic and not-for-profit vaccine researchers and developers including
the  National  Institutes  of  Health.  The  industry  is  typified  by  extensive  collaboration,  licensing,  and  merger  and  acquisition  activity  despite  the  intense
competition.

Within the hepatitis B vaccine space, we have several key competitors currently commercializing monovalent hepatitis B vaccines, including: GSK,
the  manufacturer  of  Engerix-B,  Merck,  the  manufacturer  of  Recombivax  HB,  and  Dynavax,  the  manufacturer  of  Heplisav-B.  While  Engerix-B  and
Recombivax HB are approved globally, Heplisav-B is currently only approved in the United States.

Within the therapeutic hepatitis B space, we face both competition from and potential collaboration with other developers of innovative hepatitis B
therapeutics designed to achieve a hepatitis B functional cure either as a monotherapy or in combination with other therapeutics. Key large pharmaceutical
companies in the space include: GSK, Janssen, Gilead Sciences, Inc, and F. Hoffmann-La Roche Ltd (“Roche”). Additionally, there are a number of mid-size
companies developing alternative approaches to treat hepatitis B, including: VIR Biotechnology Inc., Arbutus Biopharma Corp, Dicerna Pharmaceuticals Inc,
and Assembly Biosciences, Inc. It is not yet known which mode of action, or combinations thereof, will lead to a hepatitis B functional cure.

Given the significant unmet medical need for GBM, there are numerous competitors seeking to develop new immunotherapies or vaccines to treat
GBM.  Among  these,  Immunomic  Therapeutics  Inc  (“Immunomic”),  Immatics  Biotechnologies  GmBH,  Stemline  Therapeutics  Inc.,  Mimivax  LLC,  and
Inovio Pharmaceuticals Inc are developing vaccines that are also currently completing Phase II studies. Immunomic’s approach also targets CMV antigens
associated with GBM using a dendritic cell vaccine. Additional cell-based therapies and oncolytic viruses include those under clinical study by DNAtrix Inc,
Transgene SA, and Ziopharm Oncology Inc.

Within the CMV vaccine space, we have several key competitors, some of whom are further advanced with their CMV vaccine development. Among
these,  Merck’s  replication-defective  CMV  vaccine  entered  Phase  II  testing  in  2019  and  Moderna  Inc’s  mRNA-based  CMV  vaccine  is  in  Phase  II.
Additionally, Hookipa Biotech AG is engaged in clinical development of a prophylactic CMV vaccine.

Suppliers, Contractors and Collaborations

Suppliers

We currently rely on a single source for our supply of vials and certain raw materials required for the manufacturing of Sci-B-Vac. We have supply
agreements with these vendors intended to assure quality and flow of materials. Alternative sources from which we can obtain our supply of these materials is
under assessment. We may not be able to find alternative suppliers in a timely manner that would provide supplies of these materials at acceptable quantities
and prices, if at all. Any interruption in the supply of these materials would disrupt our ability to manufacture Sci-B-Vac and could have a material adverse
effect on our business.

Contractors

We  enter  into  contracts  in  the  normal  course  of  business  with  contract  research  organizations  (“CROs”)  for  clinical  trials  and  with  vendors  for

research studies, research supplies and other services and products for operating purposes. These contracts generally provide for termination on notice.

We engage CRO’s to conduct our clinical programs including the ongoing GBM Phase I/IIa clinical program and the completed Sci-B-Vac Global
Phase III clinical program. Our reliance on these CRO’s reduces our control over these activities and involves certain risks. See “Risk Factors” on page 21 for
more information regarding the risks associated with our reliance on CROs.

We  rely  on  a  number  of  contractors  to  provide  services  to  characterize  and  release  Sci-B-Vac  for  Israel  and  other  markets.  While  alternative
contractors  exist  for  these  services,  we  may  not  be  able  to  transition  to  alternative  contractors  in  a  manner  that  does  not  disrupt  the  normal  course  of
manufacturing operations and the supply of Sci-B-Vac.

Our novel vaccine development efforts depend on a number of key suppliers to continue our research operations. We have identified the following

parties as key suppliers of reagents, technology or expertise which impact our development plans with our eVLP pipeline candidates:

● UPMC  is  the  owner  of  the  eVLP  vaccine  platform  IP  portfolio  to  which  we  have  an  exclusive  license.  Under  the  terms  of  the  ePixis  License
Agreement, as amended, we are required to pay royalties for successful products developed using the IP for as long as claims remain valid in a given
jurisdiction. This patent portfolio has claims that are expected to remain valid until 2022 in the United States and 2021 in other countries, after which
time we are no longer obligated to compensate UPMC for development of vaccines based on the UPMC IP portfolio. After that time, the remaining
patent protection of the CMV vaccine candidate will be based on patent applications co-owned with UPMC which, if granted, would provide patent
protection extending until 2032. We are currently negotiating extension of the ePixis License Agreement to cover the CMV patents. There can be no
assurance that any such patent applications will be granted or, if granted, be enforceable, and they may be amended to reduce the scope of patent
claims.

● We have collaborated with NRC on various vaccine projects since 2004 and have a long history of successful partnerships including several NRC-
funded industrial research grants. The NRC developed a proprietary cell line (HEK-293-NRC) that we are using for production of our eVLP-based
CMV vaccine candidate. VBI Cda and the NRC have signed a research agreement that provides VBI Cda with access to NRC facilities and expertise
for the advancement of the CMV vaccine candidate program. Supplementary to such research agreement, we negotiated terms for a non-exclusive
license to the HEK-293-NRC cell line. Under these terms, we were required to pay success-based milestone payments until the patents on the cell
line expired in November of 2018.

● Key  Reagent  Suppliers:  Characterization  and  release  assays  for  our  eVLP-based  vaccines  require  specialized  reagents.  Several  key  reagents
including  reference  proteins  and  growth  media  are  provided  by  third  parties  and  can  impact  development  timelines.  We  have  secured  sufficient
quantities of third-party reference proteins and growth media for ongoing and planned clinical studies. Supply of these key reagents remains a risk.
See “Risk Factors” on page 21 for more information regarding the risks associated with our reliance on key reagents.

● We,  through  our  wholly-owned  subsidiaries,  depend  on  subcontractor  arrangements  to  facilitate  the  completion  of  our  research  programs.  For
example, Catalent Biologics, previous Paragon Bioservices, has manufactured clinical batches of our CMV vaccine candidate pursuant to the terms
of  a  GMP-Manufacturing  Services  Agreement  (the  “Services  Agreement”)  dated  September  26,  2014.  In  addition,  pursuant  to  the  Services
Agreement,  Catalent  Biologics,  previous  Paragon  Bioservices,  has  manufactured  clinical  quantities  of  our  GBM  vaccine  immunotherapeutic
candidate. The term of the Services Agreement is indefinite, although either party may terminate the Services Agreement upon written notice to the
other party. The Company continues to explore alternative sources of product supply.

Collaborations

We also enter into contracts in the normal course of business with vendors for preclinical safety and research studies, research supplies and other
services  and  products  for  operating  purposes.  These  contracts  generally  provide  for  termination  on  notice  and  do  not  include  any  minimum  purchase
commitments, and therefore are cancellable contracts.

● On December  4,  2018,  we  entered  into  the  License  Agreement  with  Brii  Bio,  pursuant  to  which,  among  other  things,  the  parties  have  agreed  to
collaborate on the development of a protein based immunotherapeutic candidate for treatment of hepatitis B subject to terms and conditions set forth
in the License Agreement as described in “Part I - Item I - Business - Contractual Arrangements”. On November 14, 2019 we announced initiation of
enrollment in a Phase Ib/IIa Study of VBI-2601 (BRII-179) in patients with chronic hepatitis B infection.

● On September 10, 2019, we entered into the Collaboration Agreement with GSK pursuant to which we will investigate the use of GSK’s proprietary
AS01B adjuvant in our ongoing Phase I/IIa study of VBI-1901. As a result of the Collaboration Agreement, we have added a second study arm to
Part  B  of  the  study  and  announced  enrollment  of  patients  in  the  AS01B arm  in  March  2020,  as  described  in  “Part  I  -  Item  I  -  Business  -  eVLP
Platform - VBI-1901: Cancer Vaccine Immunotherapeutic Candidate”.

Employees

As of December 31, 2019, we had a total of 123 full-time and 2 part-time employees. The SciVac manufacturing site in Israel had 85 full-time employees
and 1 part-time employee and the VBI Cda research site employed 31 full-time and 1 part-time employee, as of December 31, 2019. The remaining 7 full-
time  employees  worked  out  of  our  headquarters  in  Cambridge,  MA.  None  of  our  employees  are  represented  by  unions.  Our  management  considers  its
relationship with our employees to be good.

Facilities and Offices

Our registered office is located at Suite 1700, Park Place, 666 Burrard Street, Vancouver, BC V6C 2X8 with our headquarters located at 222 Third Street,
Suite  2241,  Cambridge,  MA  02142.  Our  manufacturing  operations  are  located  in  Rehovot,  Israel  and  our  primary  research  facility  is  located  in  Ottawa,
Ontario, Canada, refer to “Part I – Item 2. Properties.”

We rent office, manufacturing and research facility space under various operating leases, and we made rent payments of $1,128 during the fiscal year

ended December 31, 2019.

We believe that our office, manufacturing and research facilities are suitable and adequate for our current operations but will consider term extensions or

expansion of leased space, depending on market conditions and needs.

Research and Development

We invest heavily in R&D. R&D expenses were $26 million and $38 million for the years ended December 31, 2019 and 2018, respectively. All R&D
was funded by equity financings, term loan financings, collaboration agreements or government grants. Our most significant R&D expenses to date have been
related to Sci-B-Vac, and the development of our CMV candidate, our GBM vaccine immunotherapeutic candidate, and the related eVLP platform. Our R&D
expenses are expected to decrease as the Phase III Sci-B-Vac clinical program is complete, however we plan to continue to invest in the Phase I/IIa GBM
clinical program, further development of our hepatitis B immunotherapeutic candidate and our CMV prophylactic vaccine candidate. In addition, we may
bring other pipeline candidates through the clinical development stage and explore other vaccine opportunities and/or collaborations.

Intellectual Property

Patents

Our IP portfolio includes 18 active patent families consisting of 142 fully owned or co-owned or exclusively licensed patents and patent applications. The

highlights of our patent portfolio include:

●

●

●

●

●

eVLP vaccine related IP: we have an exclusive license to a patent family that protect the eVLP vaccine platform and derivatives thereof. Among
these patents are rights that were originally developed at the UPMC, with which we hold a world-wide exclusive license to the base technology
for the design of an eVLP.

GBM  vaccine  immunotherapeutic  candidate  related  IP:  we  own  or  co-own  three  patent  families  which  directly  address  our  GBM  vaccine
immunotherapeutic candidate. These patents and applications include claims to compositions of matter and methods of treating GBM patients.

CMV vaccine candidate related IP: we own or co-own two patent families which directly address our CMV vaccine candidate. These patents
include a composition of matter patent describing the CMV vaccine candidate as well as a proprietary assays used to provide high-throughput
screening of anti-CMV vaccine candidate responses.

Hepatitis  B  Immunotherapeutic  candidate  related  IP:  we  own  or  co-own  two  patent  families  which  directly  address  our  hepatitis  B
immunotherapeutic candidate. These patent applications include claims to compositions of matter and methods of treating hepatitis B patients.

Lipid Particle  Vaccines  (“LPV”)  vaccine  related  IP:  we  own  six  patent  families  which  protect  our  LPV  technology  platform.  These  patents
include the method for manufacturing an LPV so as to confer thermostability, the proprietary ratios of excipients and antigens that are required
to  give  rise  to  a  thermostable  formulation,  and  specific  parameters  required  to  confer  thermostability  to  several  distinct  classes  of  vaccine
antigens and biologic proteins.

We have a process of continuously monitoring the competitive landscape for infectious disease vaccines to better understand the research, business
and patent activities of our academic and industrial competitors. This process helps management to understand the competitive positioning of our pipeline.
This  knowledge  has  informed  and  shaped  our  patent  portfolio,  which  is  designed  to  protect  our  proprietary  vaccine  technologies  and  establish  a  defense
against third-party infringement claims. Our licensed patent family relating to virus like particles (7 of which have now been issued) has a patent term that
extends to 2022 and in the United States and 2021 in other countries. Our most recently filed patent family will have a patent term that extends to 2039.

Trade Secrets

Some  of  our  know-how  and  technology  is  not  patentable.  To  protect  our  proprietary  rights  in  unpatentable  intellectual  property  and  trade  secrets,  we

require employees, consultants, advisors and collaborators to enter into agreements regarding intellectual property and confidentiality information.

Trademarks

We use the Sci-B-Vac trademarks in connection with our hepatitis B virus vaccine product. We have registered these trademarks in 16 countries. The

trademarks are renewable indefinitely, so long as we make the appropriate filings when required. We also have a registration for the LPV mark in Canada.

Governmental Regulation and Product Approval

Vaccine development is a highly regulated field. The manufacturing and marketing of our potential products and our ongoing research and development
activities are subject to extensive regulation by the FDA and comparable regulatory agencies of local, state and foreign jurisdictions, such as Health Canada in
Canada. New products must go through extensive preclinical and clinical development prior to product launch. This process can take more than ten years
from  candidate  identification  to  licensure/marketing  approval  by  health  authorities  worldwide.  Despite  efforts  to  harmonize  regulatory  requirements  in
different jurisdictions, there exists a divergence of legal and regulatory requirements in different countries and territories. Delays in regulatory approval to
move from one stage of development to another can potentially cause us significant delays and can affect our market capitalization.

United States, Europe and Canada Regulatory Agencies

Before  any  of  our  products  can  be  marketed  and  sold  in  the  United  States,  Europe  or  Canada,  they  must  receive  approval  from  the  relevant
regulatory agencies, including the FDA, EMA or Health Canada, respectively. To receive regulatory approvals to market any drug or vaccine, including those
we develop, the products in development must undergo rigorous preclinical testing and clinical studies that demonstrate the product’s safety and effectiveness
for  each  indicated  use.  This  extensive  regulatory  path  includes  process  controls  in  development,  testing,  manufacturing,  safety,  efficacy,  record  keeping,
labeling, storage, approval, advertising, promotion, sale, and distribution of the pharmaceutical products.

In general, before any new pharmaceutical or biological product can be marketed in the mentioned geographical areas, the process typically required

by the regulatory agencies includes:

●

●

●

●

●

●

Preclinical Testing

preclinical toxicology, laboratory and animal tests;

submission of an investigational new drug application (an “IND”) in the United States, which must be reviewed by the FDA  before
human  clinical  trials  may  begin;  submission  of  a  Scientific  Advice  application  to  EMA  in  Europe  or  submission  of a Clinical Trial
Application to Health Canada;

adequate and well-controlled human clinical trials to establish the safety and efficacy of the proposed drug for its intended use;

pre-approval inspection of manufacturing facilities and selected clinical investigator sites;

submission of a BLA to the FDA, a MAA to the EMA; a NDS to Health Canada; and

FDA approval of a BLA or a BLA supplement (for subsequent indications or other modifications, including a change in location of the
manufacturing facility). EMA approval of the MAA. Health Canada approval of the NDS.

In  the  United  States,  drug  candidates  are  tested  in  animals  until  adequate  proof  of  safety  and  efficacy  is  established.  These  preclinical  studies
generally evaluate the mechanism of action and pharmacology of the product and assess the potential safety and efficacy of the product. Tested compounds
must be produced according to applicable current GMP requirements and preclinical safety tests must be conducted in compliance with FDA and international
regulations regarding good laboratory practices. The results of the preclinical tests, together with manufacturing information and analytical data, are generally
submitted  to  the  FDA  as  part  of  an  IND,  which  must  become  effective  before  human  clinical  trials  may  commence.  The  IND  will  automatically  become
effective 30 days after receipt by the FDA, unless before that time the FDA requests an extension or raises concerns about the conduct of the clinical trials as
outlined in the application. If the FDA has any concerns, the sponsor of the application and the FDA must resolve those concerns before clinical trials may
begin. Regulatory authorities may require additional preclinical data before allowing the clinical studies to commence or proceed from one phase to another,
and could demand that the studies be discontinued or suspended at any time if there are significant safety issues. Furthermore, an independent institutional
review board for each medical center proposing to participate in the conduct of the clinical trial must review and approve the clinical protocol and patient
informed consent form before commencement of the study at the respective medical center.

Clinical Trials

Clinical trials for new vaccine drug candidates are typically conducted in three sequential phases that may overlap. In Phase I, the initial introduction
of  the  vaccine  drug  candidate  into  human  volunteers,  the  emphasis  is  on  testing  for  safety  or  adverse  effects,  dosage,  tolerance,  metabolism,  distribution,
excretion, and clinical pharmacology. Phase II involves studies in a limited patient population to determine the initial efficacy of the vaccine drug candidate
for  specific  targeted  indications,  to  determine  dosage  tolerance  and  optimal  dosage,  and  to  identify  possible  adverse  side  effects  and  safety  risks.  Once  a
vaccine  compound  shows  evidence  of  effectiveness  and  is  found  to  have  an  acceptable  safety  profile  in  Phase  II  evaluations,  pivotal  Phase  III  trials  are
undertaken to more fully evaluate clinical outcomes and to establish the overall risk/benefit profile of the drug, and to provide, if appropriate, an adequate
basis for product labeling. During all clinical trials, physicians will monitor patients to determine the effectiveness of the drug candidate and to observe and
report any reactions or safety risks that may result from use of the vaccine drug candidate. The FDA, the trial sites internal review board and/or the sponsor
may suspend a clinical trial at any time on various grounds, including a finding that the subjects are being exposed to an unacceptable health risk.

Assuming  successful  completion  of  all  required  testing  in  accordance  with  all  applicable  regulatory  requirements,  the  results  of  product
development, nonclinical studies and clinical trials are submitted to the FDA as part of a BLA requesting approval to market the product for one or more
indications. The submission of a BLA requires payment of a substantial user fee to the FDA, and the sponsor of an approved BLA is also subject to annual
product and establishment user fees. These fees are typically increased annually. A waiver of user fees may be obtained under certain limited circumstances.
Under  applicable  laws  and  FDA  regulations,  each  BLA  submitted  for  FDA  approval  is  usually  given  an  internal  administrative  review  within  60  days
following submission of the BLA. If deemed complete, the FDA will “file” the BLA, thereby triggering substantive review of the application. The FDA may
refuse to file any BLA that it deems incomplete or not properly reviewable. The FDA has established internal substantive review goals of six months for
priority BLAs (for biologics addressing serious or life-threatening conditions for which there is an unmet medical need) and ten months for regular BLAs.
However, these are agency proposed time frames, and so the FDA is not legally required to complete its review within these periods, and these performance
goals may change over time. Moreover, the outcome of the review, even if generally favorable, is not typically an actual approval, but an “action letter” that
describes additional work that must be done before the BLA can be approved. The FDA’s review of a BLA may involve review and recommendations by an
independent FDA advisory committee. The FDA may deny approval of a BLA or BLA supplement if the applicable regulatory criteria are not satisfied, or the
FDA may require additional clinical data and/or an additional pivotal Phase III clinical study. Even if such data are submitted, the FDA may ultimately decide
the BLA or BLA supplement does not satisfy its criteria for approval.

Data Review and Approval

Substantial  financial  resources  are  necessary  to  fund  the  research,  clinical  trials  and  related  activities  necessary  to  satisfy  FDA  requirements  or
similar requirements of state, local and foreign regulatory agencies. It normally takes many years to satisfy these various legal and regulatory requirements,
assuming they are ever satisfied. Information generated in this process is susceptible to varying interpretations that could delay, limit, or prevent regulatory
approval at any stage of the process. Accordingly, the actual time and expense required to bring a product to market may vary substantially. We cannot assure
you that we will submit applications for required authorizations to manufacture and/or market potential products or that any such application will be reviewed
and approved by the appropriate regulatory authorities in a timely manner, if at all. Success in early stage clinical trials does not ensure success in later stage
clinical  trials.  Even  if  a  product  candidate  receives  regulatory  approval,  the  approval  may  be  significantly  limited  to  specific  disease  states,  patient
populations and dosages, or have conditions placed on them that restrict the commercial applications, advertising, promotion or distribution of these products.

Once  issued,  the  FDA  may  withdraw  product  approval  if  ongoing  regulatory  standards  are  not  met  or  if  safety  problems  occur  after  the  product
reaches  the  market.  In  addition,  the  FDA  may  require  testing  and  surveillance  programs  to  monitor  the  effect  of  approved  products  which  have  been
commercialized. The FDA also has the power to prevent or limit further marketing of a product based on the results of these post-marketing programs. The
FDA may also request additional clinical trials after a product is approved. These so-called Phase IV studies may be made a condition to be satisfied after a
drug receives approval. The results of Phase IV studies can confirm the effectiveness of a product candidate and can provide important safety information via
the  FDA’s  voluntary  adverse  drug  reaction  reporting  system.  Any  products  manufactured  or  distributed  by  us  pursuant  to  any  FDA  approvals  would  be
subject to continuing regulation by the FDA, including record-keeping requirements and reporting of adverse experiences with the drug. Drug and biologics
manufacturers  and  their  subcontractors  are  required  to  register  their  establishments  with  the  FDA  and  certain  state  agencies,  and  are  subject  to  periodic
unannounced inspections by the FDA and certain state agencies for compliance with GMP, which impose certain procedural and documentation requirements
upon us and our third-party manufacturers. We cannot be certain that we or our present or future suppliers will be able to comply with the GMP regulations
and other FDA regulatory requirements. If our present or future suppliers are not able to comply with these requirements, the FDA may halt our clinical trials,
require us to recall a product from distribution, withdraw approval of the NDA for that drug, or revoke or suspend a biologics license. Furthermore, even after
regulatory  approval  is  obtained,  later  discovery  of  previously  unknown  negative  effects  of  a  product  may  result  in  restrictions  on  the  product  or  even  its
complete withdrawal from the market.

The FDA closely regulates the marketing and promotion of drugs and biologics. Approval is typically subject to post-marketing surveillance and
other  record  keeping  and  reporting  obligations,  and  involves  ongoing  requirements  such  as  post-marketing  annual  reports  and  labeling  updates.  Product
approvals  may  be  withdrawn  if  compliance  with  regulatory  standards  is  not  maintained  or  if  problems  occur  following  initial  marketing.  A  company  can
make  only  those  claims  relating  to  safety  and  efficacy  that  are  approved  by  the  FDA.  Failure  to  comply  with  these  requirements  can  result  in  adverse
publicity, warning letters, corrective advertising and potential civil and/or criminal penalties. Physicians may prescribe legally available drugs for uses that are
not described in the product’s labeling and that differ from those tested by us and approved by the FDA. Such off-label uses are common across medical
specialties. Physicians may believe that such off-label uses are the best treatment for many patients in varied circumstances. The FDA does not regulate the
behavior of physicians in their choice of treatments. The FDA does, however, restrict manufacturers’ communications on the subject of such off-label use.

Biologics Price Competition and Innovation Act of 2009 (BPCIA)

Under the Federal Patient Protection and Affordable Care Act (the “Affordable Care Act”), enacted in 2010, and specifically, the Biologics Price
Competition and Innovation Act of 2009 (BPCIA) included therein, there is an abbreviated path in the United States for regulatory approval of biosimilar
versions of approved biological products. The Affordable Care Act provides a regulatory mechanism that enables FDA approval of biologic drugs that are
similar to (but not exact copies of) innovative drugs on the basis of less extensive data than is required by a full BLA. Under this regulation, an application for
approval  of  a  biosimilar  may  not  be  filed  until  four  years  after  marketing  approval  of  the  innovator  product.  Pioneer  innovative  biological  products  will
receive 12 years of regulatory exclusivity, meaning that the FDA will not approve a biosimilar version until 12 years after the innovative biological product
was first approved by the FDA.

Fast Track Approval

The Federal Food, Drug, and Cosmetic Act (“FDCA”), as amended, and the related FDA regulations provide certain mechanisms for the accelerated
“Fast  Track”  approval  of  potential  products  intended  to  treat  serious  or  life-threatening  illnesses  which  have  demonstrated  the  potential  to  address  unmet
medical needs. These procedures permit early consultation and commitment from the FDA regarding the preclinical and clinical studies necessary to gain
marketing approval. Provisions of this regulatory framework also permit, in certain cases, BLAs to be approved on the basis of valid indirect measurements of
benefit  of  product  effectiveness,  thus  accelerating  the  normal  approval  process.  In  the  future,  certain  potential  products  employing  our  technology  might
qualify for this accelerated regulatory procedure. Even if the FDA agrees that these potential products qualify for accelerated approval procedures, FDA may
deny approval of our drugs or may require additional studies before approval. The FDA may also require us to perform post-approval, or Phase IV, studies as
a  condition  of  such  early  approval.  In  addition,  the  FDA  may  impose  restrictions  on  distribution  and/or  promotion  in  connection  with  any  accelerated
approval, and may withdraw approval if post-approval studies do not confirm the intended clinical benefit or safety of the potential product.

Orphan Drug Designation

Under the Orphan Drug Act, the FDA may grant orphan drug designation to drugs or biologics intended to treat a rare disease or condition, which is
generally a disease or condition that affects fewer than 200,000 individuals in the United States. Orphan drug designation must be requested before submitting
a BLA. After the FDA grants orphan drug designation, the identity of the therapeutic agent and its potential orphan use are disclosed publicly by the FDA.
Orphan drug designation does not convey any advantage in or shorten the duration of the regulatory review and approval process. If a product that has orphan
drug designation subsequently receives FDA approval for the disease for which it has such designation, the product is entitled to orphan product exclusivity,
which means that FDA may not approve any other applications to market the same drug for the same disease, except in very limited circumstances, for seven
years. These very limited circumstances are (i) an inability to supply the drug in sufficient quantities or (ii) a situation in which a new formulation of the drug
has shown superior safety or efficacy. This exclusivity, however, also could block the approval of our product for seven years if a competitor obtains earlier
approval of the same drug for the same indication.

19

 
 
 
 
 
 
 
 
Foreign Regulation

In addition to regulations in the United States, we are and will continue to be subject to a variety of laws and regulations governing clinical trials and
commercial  sales  and  distribution  of  our  products  in  foreign  countries.  Whether  or  not  we  obtain  FDA  approval  for  a  product,  we  must  separately  obtain
approval of a product by the comparable regulatory authorities of those foreign countries before we may commence clinical trials or marketing of the product
in  those  countries.  The  approval  process  varies  from  country  to  country,  and  the  time  may  be  longer  or  shorter  than  that  required  for  FDA  approval.  The
requirements governing the conduct of clinical trials, product licensing, pricing and reimbursement vary greatly from country to country.

Under  the  applicable  EU  regulatory  systems,  we  may  submit  marketing  authorization  applications  either  under  a  centralized  or  decentralized
procedure. The centralized procedure, which is available for medicines produced by biotechnology or which are highly innovative, provides for the grant of a
single  marketing  authorization  that  is  valid  for  all  EU  member  states.  This  authorization  is  an  MAA.  The  decentralized  procedure  provides  for  mutual
recognition of national approval decisions.

Under  this  decentralized  procedure,  the  holder  of  a  national  marketing  authorization  may  submit  an  application  to  the  remaining  member  states.
Within 90 days of receiving the applications and assessment report, each member state must decide whether to recognize approval. This procedure is referred
to as the mutual recognition procedure.

The policies of the FDA and foreign regulatory authorities may change and additional government regulations may be enacted which could prevent
or delay regulatory approval of our products and could also increase the cost of regulatory compliance. For example, the procedure for obtaining marketing
approval in the United Kingdom will be affected by Brexit, which took place on January 31, 2020. A transitional period is in place until December 31, 2020,
during  which  time  regulation  of  pharmaceuticals  will  be  governed  by  EU  law.  However,  it  is  not  known  at  this  time  whether  EU  law  will  continue  to  be
applied  after  this  period,  or  whether  a  separate  regulatory  system  will  be  established  in  the  United  Kingdom.  We  cannot  predict  the  likelihood,  nature  or
extent of adverse governmental regulation that might arise from future legislative or administrative action, either in the United States or abroad.

Other Government Regulation

Our research and development activities use biological and hazardous materials that are dangerous to human health and safety or the environment.
We  are  subject  to  a  variety  of  federal,  provincial,  state  and  local  laws  and  regulations  governing  the  use,  generation,  manufacture,  storage,  handling  and
disposal of these materials and wastes resulting from these materials. We are also subject to regulation by the Occupational Safety and Health Administration
and federal, provincial and state environmental protection agencies and to regulation under the Toxic Substances Control Act.

In addition, once our products are marketed commercially, we will have to comply with the various laws relating to the Medicare, Medicaid and

other federal healthcare programs. These federal laws include, by way of example, the following:

● The anti-kickback statute (Section 1128B(b) of the Social Security Act) which prohibits certain business practices and relationships that might affect the
provision and cost of healthcare services reimbursable under Medicare, Medicaid and other federal healthcare programs, including the payment or receipt
of remuneration for the referral of patients whose care will be paid by Medicare or other governmental programs;

● The physician self-referral prohibition (Ethics in Patient Referral Act of 1989, as amended, commonly referred to as the Stark Law, Section 1877 of the
Social Security Act), which prohibits referrals by physicians of Medicare or Medicaid patients to providers of a broad range of designated healthcare
services  in  which  the  physicians  (or  their  immediate  family  members)  have  ownership  interests  or  with  which  they  have  certain  other  financial
arrangements;

● The anti-inducement law (Section 1128A(a)(5) of the Social Security Act), which prohibits providers from offering anything to a Medicare or Medicaid

beneficiary to induce that beneficiary to use items or services covered by either program;

● The False Claims Act (31 U.S.C. § 3729 et seq.), which prohibits any person from knowingly presenting or causing to be presented false or fraudulent

claims for payment to the federal government (including the Medicare and Medicaid programs); and

● The Civil Monetary Penalties Law (Section 1128A of the Social Security Act), which authorizes the United States Department of Health and Human

Services to impose civil penalties administratively for fraudulent or abusive acts.

20

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Sanctions  for  violating  these  federal  laws  include  criminal  and  civil  penalties  that  range  from  punitive  sanctions,  damage  assessments,  money
penalties, imprisonment, denial of Medicare and Medicaid payments, or exclusion from the Medicare and Medicaid programs, or some combination thereof.
These laws also impose an affirmative duty on those receiving Medicare or Medicaid funding to ensure that they do not employ or contract with persons
excluded from Medicare and other government programs.

We are building our government relations and regulatory capabilities by leveraging consultants who have extensive experience with the regulatory

process.

We  also  use  additional  regulatory  consultants  including  several  former  FDA  regulators  with  experience  at  the  Center  for  Biologics  Evaluation  &

Research (“CBER”) which is the division of FDA that regulates vaccines and other drugs.

ITEM 1A: RISK FACTORS

We are subject to various risks that may materially harm our business, prospects, financial condition and results of operations. An investment in our
common shares is speculative and involves a high degree of risk. In evaluating an investment in our common shares, you should carefully consider the risks
described below, together with the other information included in this Form 10-K, including the consolidated financial statements and related notes.

The risks described below are not the only risks we face. If any of the events described in the following risk factors actually occurs, or if additional
risks and uncertainties later materialize, that are not presently known to us or that we currently deem immaterial, then our business, prospects, results of
operations and financial condition could be materially adversely affected. In that event, the trading price of our common shares could decline, and you may
lose all or part of your investment in our shares. The risks discussed below include forward-looking statements, and our actual results may differ substantially
from those discussed in these forward-looking statements.

Risks Related to Our Product Development

Because  our  product  development  efforts  depend  on  new  and  rapidly  evolving  technologies,  we  cannot  be  certain  that  our  efforts  will  be

successful.

Our  product  development  efforts  depend  on  new,  rapidly  evolving  technologies  and  on  the  marketability  and  profitability  of  our  products.

Commercialization of our vaccines could fail for a variety of reasons, and include the possibility that:

● Sci-B-Vac may not be approved for sale in the United States, Europe or Canada;

● our eVLP vaccine technologies, any or all of the products based on such technologies or our manufacturing process will be ineffective or unsafe, or

otherwise fail to receive necessary regulatory clearances or achieve commercial viability;

21

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
● we or Brii Bio may be unable to successfully carry out the development and commercialization plans under the Brii License Agreement;

● we may be unable to develop a scale-up method for our manufacturing protocols in a cost-effective manner;

● the products, if safe and effective, will be difficult to manufacture on a large-scale or may be uneconomical to market;

● our subcontracted third-party manufacturing facility may fail to continue to pass regulatory inspections;

● proprietary rights of third parties will prevent us or our collaborators from exploiting technologies, and manufacturing or marketing products; and

● third-party competitors will gain greater market share due to superior products or marketing capabilities.

The  FDA  and  corresponding  foreign  regulatory  agencies  may  require  more  clinical  trials  for  our  Sci-B-Vac  than  we  currently  expect  or  are

conducting before granting regulatory approval, if regulatory approval is granted at all.

Our registration and commercial timelines for Sci-B-Vac depend on further discussions with the FDA and corresponding foreign regulatory agencies.
They could have additional requirements and requests, beyond the ongoing Phase III studies, for additional data or completion of additional clinical trials,
including a request to increase the size of the safety data set. Any such requirements or requests could:

● adversely  affect  our  ability  to  timely  and  successfully  commercialize  or  market  Sci-B-Vac  in  the  United  States,  Europe,  Canada  and  other

jurisdictions where Sci-B-Vac is not currently approved;

● result in significant additional costs;

● potentially diminish any competitive advantages for Sci-B-Vac;

● potentially limit the markets for Sci-B-Vac;

● adversely affect our ability to enter into collaborations or receive milestone payments or royalties from potential collaborators;

● cause  us  to  abandon  the  further  development  of  Sci-B-Vac  or  certain  of  our  pipeline  candidates  to  comply  with  requests  by  the  FDA  or  other

jurisdictions where it is not currently approved; or

● limit our ability to obtain additional financing on acceptable terms, if at all.

Pre-clinical and clinical trials will be lengthy and expensive. Delays in clinical trials are common for many reasons and any such delays could

result in increased costs to us and jeopardize or delay our ability to obtain regulatory approval and commence product sales as currently contemplated.

As part of the regulatory process, we must conduct clinical trials for each vaccine candidate to demonstrate safety and efficacy to the satisfaction of
the  regulatory  authorities,  including  the  FDA  for  the  United  States,  the  EMA  for  the  European  Union  and  Health  Canada  for  Canada.  Clinical  trials  are
subject  to  current  Good  Clinical  Practice  regulations  (“cGCP”).  cGCPs  are  rigorous  practices  that  are  incorporated  into  the  FDA’s  clinical  trial  regulatory
requirements and are expensive and time-consuming to design and implement. We may experience delays in clinical trials for any of our pipeline candidates,
and  the  projected  timelines  for  continued  development  of  the  technologies  and  related  pipeline  candidates  by  us  may  otherwise  be  subject  to  delay  or
suspension. Our planned clinical trials might not begin on time; may be interrupted, delayed, suspended, or terminated once commenced; might need to be
redesigned; might not enroll a sufficient number of patients; or might not be completed on schedule, if at all. Clinical trials can be delayed for a variety of
reasons, including the following:

22

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
● delays in obtaining regulatory approval to commence a trial;

● imposition of a clinical hold following an inspection of our clinical trial operations or trial sites by the FDA or other regulatory authorities;

● imposition of a clinical hold because of safety or efficacy concerns by the FDA, a data safety monitoring board or committee, a clinical trial

site’s institutional review board, or us;

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

● delays in obtaining required institutional review board approval at each site for clinical trial protocols;

● delays in identifying, recruiting and training suitable clinical investigators;

● delays in recruiting suitable patients to participate in a trial;

● delays in having patients complete participation in a trial or return for post-treatment follow-up;

● clinical sites dropping out of a trial to the detriment of enrollment;

● time required to add new sites;

● delays in obtaining sufficient supplies of clinical trial materials, including comparator drugs;

● delays resulting from negative or equivocal findings of a data safety monitoring board for a trial; or

● adverse or inconclusive results from pre-clinical testing or 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 biologic being studied in relation to other available therapies, including any new biologics that
may be approved for the indications we are investigating. Any of these delays in completing our clinical trials could increase costs, slow down the product
development and approval process, and jeopardize our ability to commence product sales and generate revenue.

Development of sufficient and appropriate clinical protocols to demonstrate safety and efficacy are required, and we may not adequately develop

such protocols to support approval.

In  addition  to  FDA  requirements  and  those  of  other  regulatory  authorities,  an  independent  institutional  review  board  or  an  independent  ethics
committee at each medical institution proposing to participate in the conduct of the clinical trial generally must review and approve the clinical trial design
and  patient  informed  consent  form  before  commencement  of  the  study  at  the  respective  medical  institution.  The  institutional  review  boards  approve  the
clinical trial protocols and conduct periodic reviews of the clinical trials. The clinical trial protocols describe the type of people who may participate in the
clinical trial, the schedule of tests and procedures, the medications and dosages to be studied, the length of the study, the study’s objectives, and other details.
In general, the institutional review board will consider, among other matters, ethical factors, the safety of human subjects and the possibility of liability of the
institution  conducting  the  trial.  Our  preclinical  studies  may  not  be  adequate  proof  of  safety  and  efficacy,  and  as  a  result,  we  may  not  be  successful  in
developing clinical trial protocols necessary to support institutional review board approval. Any delay or failure to obtain institutional review board approval
to conduct a clinical trial at a prospective site could materially impact the costs, timing or successful completion of a clinical trial.

We  rely  on  CROs,  third-party  investigators,  and  independent  sites  to  conduct  our  clinical  trials.  If  these  third  parties  do  not  fulfill  their
contractual  obligations  or  meet  expected  deadlines,  our  planned  clinical  trials  may  be  extended,  delayed,  modified,  or  terminated  and  we  may  fail  to
obtain the regulatory approvals necessary to commercialize our pipeline candidates.

We rely on third-party CROs to conduct our clinical trials, including the Sci-B-Vac Phase III clinical studies. CROs, third-party investigators, and
independent  sites  are  subject  to  cGCPs  that  include  conducting,  recording,  and  reporting  the  results  of  clinical  trials  and  to  assure  that  data  and  reported
results are credible and accurate and that the rights, integrity and confidentiality of trial participants are protected. The FDA enforces cGCPs through periodic
inspections.  If  these  CROs  do  not  perform  their  obligations,  comply  with  laws  or  cGCPs,  or  meet  expected  deadlines,  our  planned  clinical  trials  may  be
extended, delayed, modified or terminated. We rely on the processes of our CROs to ensure that accurate records are maintained to support the results of the
clinical trials. While we or our CROs conduct regular monitoring of clinical sites, we are dependent on the processes and quality control efforts of our third-
party contractors to ensure that detailed, quality records are maintained to support the results of the clinical trials that they are conducting on our behalf. Any
extension, delay, modification or termination of our clinical trials or failure to ensure adequate documentation and the quality of the results in the clinical
trials could delay or otherwise adversely affect our ability to commercialize our products and pipeline candidates and could have a material adverse effect on
our business and operations.

We rely upon independent sites and investigators, such as universities and medical institutions and their faculty or staff, to conduct our clinical trials.
These  sites  and  investigators  are  not  our  employees  and  we  cannot  control  the  amount  or  timing  of  resources  that  they  devote  to  our  programs.  If  these
investigators or collaborators fail to devote sufficient time and resources to our product development programs, do not conduct their activities in compliance
with the law, or if their performance is substandard, the approval of our regulatory submissions and our introductions of new products will be delayed or
prevented.

Our potential collaborators may also have relationships with other commercial entities, some of which may compete with us. If outside collaborators
assist  our  competitors  to  our  detriment,  the  approval  of  our  regulatory  submissions  will  be  delayed  and  the  sales  from  our  products,  if  and  when
commercialized, will be less than expected. Even if clinical trials are completed as planned, their results may not support expectations or intended marketing
claims. The clinical trials process may fail to demonstrate that our pipeline candidates are safe and effective for indicated uses. Such failure could cause us to
abandon one or more pipeline candidates and could delay development of other pipeline candidates.

Additional delays to the completion of clinical studies may result from modifications being made to the protocol during the clinical trial, if such

modifications are warranted and/or required by the occurrences in the given trial.

Each modification to a protocol for a clinical trial must be submitted to the FDA or foreign regulatory authorities and the institutional review boards.
This submission could result in the delay or suspension of a clinical trial while the modification is evaluated. In addition, depending on the magnitude and
nature of the changes made, the FDA and other regulatory authorities could take the position that the data generated by the clinical trial prior to the protocol
modification cannot be pooled with the data collected after the modification because the same protocol was not used throughout the trial. This prohibition
might  require  the  enrollment  of  additional  subjects,  which  could  result  in  the  extension  of  the  clinical  trial  and  the  FDA  and  other  regulatory  authorities
delaying approval of one or more pipeline candidates.

We may be required to suspend or discontinue clinical trials because of adverse side effects or other safety risks that could preclude approval of

our biologic candidates.

Our clinical trials may be suspended or terminated at any time for a number of reasons. A clinical trial may be suspended or terminated by us, our
collaborators,  the  FDA,  or  other  regulatory  authorities  because  of  a  failure  to  conduct  the  clinical  trial  in  accordance  with  regulatory  requirements  or  our
clinical protocols, presentation of unforeseen safety issues or adverse side effects, failure to demonstrate a benefit from using the investigational biologic,
changes in governmental regulations or administrative actions, lack of adequate funding to continue the clinical trial, or negative or equivocal findings of the
data safety monitoring board or the institutional review board for a clinical trial. An institutional review board may also suspend or terminate our clinical
trials  for  failure  to  protect  patient  safety  or  patient  rights.  We  may  voluntarily  suspend  or  terminate  our  clinical  trials  if  at  any  time  we  believe  that  they
present an unacceptable risk to participants. If we elect or are forced to suspend or terminate any clinical trial of any proposed product that we develop, the
commercial prospects of such proposed product will be harmed and our ability to generate product revenue from such proposed product will be delayed or
eliminated. Any of these occurrences may harm our business, financial condition, results of operations and prospects significantly.

24

 
 
 
 
 
 
 
 
 
 
The  future  results  of  our  current  or  future  clinical  trials  may  not  support  our  pipeline  candidates  claims  or  may  result  in  the  discovery  of

unexpected adverse side effects.

Even if our clinical trials are completed as planned, we cannot be certain that the results will support our pipeline candidates claims or that the FDA
or foreign regulatory authorities will agree with our conclusions regarding them. Success in pre-clinical studies and early clinical trials does not ensure that
later clinical trials will be successful, and we cannot be sure that the later trials will replicate the results of prior trials and pre-clinical studies. The clinical
trial  process  may  fail  to  demonstrate  that  our  pipeline  candidates  are  safe  and  effective  for  the  proposed  indicated  uses.  If  the  FDA  or  foreign  regulatory
authorities  conclude  that  the  clinical  trials  for  any  of  our  pipeline  candidates  for  which  we  might  seek  approval  have  failed  to  demonstrate  safety  and
effectiveness,  we  would  not  receive  regulatory  approval  to  market  that  product  in  the  United  States  or  in  other  jurisdictions  for  the  indications  sought.  In
addition, such an outcome could cause us to abandon the pipeline candidates and might delay development of others. Any delay or termination of our clinical
trials will delay the filing of any product submissions with the FDA or foreign regulatory authorities and, ultimately, our ability to commercialize our pipeline
candidates and generate revenues. It is also possible that patients enrolled in clinical trials will experience adverse side effects that are not currently part of the
product candidate’s profile. Adverse clinical trial results, such as death or injury due to side effects, could jeopardize regulatory approval, and if approval is
granted, such results may also lead to marketing restrictions or prohibitions. In addition, the clinical trials performed for programs other than for Sci-B-Vac
involve a relatively small patient population. Because of the small sample size, their results may not be indicative of future results.

International commercialization of Sci-B-Vac and our pipeline candidates faces significant obstacles, including obtaining regulatory approvals.

Failure to obtain regulatory approval in foreign jurisdictions will prevent us from marketing or selling our products in such jurisdictions.

Sci-B-Vac  is  approved  for  sale  in  Israel.  In  countries  where  we  do  not  currently  have  the  required  approvals  (including  the  United  States,  many
European countries and Canada), we will need to obtain separate approvals from the relevant regulatory, pricing and reimbursement authorities to market or
sell Sci-B-Vac or any of our pipeline candidates. Pursuing regulatory approvals will be time-consuming and expensive, and we may not obtain United States
or  foreign  regulatory  approvals  on  a  timely  basis,  if  at  all.  The  regulations  vary  among  countries,  and  regulatory  authorities  in  one  market  may  require
different or additional clinical trials than those required to obtain approval for Sci-B-Vac or our pipeline candidates in another market, and the time required to
obtain  approval  may  differ  in  one  market  from  that  required  to  obtain  approval  for  Sci-B-Vac  or  our  pipeline  candidates  in  another  market.  Obtaining
approval in one country does not ensure approval by regulatory authorities in other countries.

In addition, we have limited international regulatory, clinical and commercial resources. We currently market or sell Sci-B-Vac through collaborative
relationships  with  foreign  partners  and  entered  into  a  collaborative  relationship  with  Brii  Bio  for  development  of  a  hepatitis  B  recombinant  protein-based
immunotherapeutic in China, Hong Kong, Taiwan and Macau, and may plan to do so with other pipeline candidates in the future, and, as such, current and
future partners are critical to our international success. We may not be able to maintain current, or enter into future, collaboration agreements with appropriate
partners for important foreign markets on acceptable terms, if at all. Current and future collaborations with foreign partners may not be effective or profitable.

Future legislation, or regulations and policies adopted by the FDA or other regulatory authorities may increase the time and costs required for

us to conduct and complete clinical trials for Sci-B-Vac and our pipeline candidates.

The  FDA  has  established  regulations,  guidelines  and  policies  to  govern  the  pharmaceutical  and  biologic  development  and  approval  processes,  as
have  foreign  regulatory  authorities.  We  expect  there  will  continue  to  be  federal  and  state  laws  and/or  regulations,  proposed  and  implemented,  that  could
impact our operations and business. Any change in regulatory requirements resulting from the adoption of new legislation, regulations or policies may require
us to amend existing clinical trial protocols or add new clinical trials to comply with these changes. Such amendments to existing protocols or clinical trial
applications or the need for new ones, may significantly and adversely affect the cost, timing and completion of the clinical trials for our candidates.

25

 
 
 
 
 
 
 
 
 
In addition, the FDA’s policies and those of other regulatory authorities may change and additional government regulations may be issued that could
prevent,  limit  or  delay  regulatory  approval  of  our  pipeline  candidates,  or  impose  more  stringent  product  labeling  and  post-marketing  testing  and  other
requirements.

Developments by competitors may establish standards of care that affect our ability to conduct our clinical trials as planned.

Changes in standards related to clinical trial design could affect our ability to design and conduct clinical trials as planned. For example, regulatory
authorities may not allow us to compare one or more of our pipeline candidates to a placebo in a particular clinical indication where approved products are
available. In that case, both the cost and the amount of time required to conduct a clinical trial could increase.

We face product liability exposure, which, if not covered by insurance, could result in significant financial liability.

The  risk  of  product  liability  is  inherent  in  the  research,  development,  manufacturing,  marketing  and  use  of  pharmaceutical  products.  Sci-B-Vac
which is currently approved for sale in Israel; our pipeline candidates currently in clinical trials; and any products that we may commercially market in the
future may cause, or may appear to have caused, injury or dangerous drug reactions, and expose us to product liability claims. These claims might be made by
patients  who  use  the  product,  healthcare  providers,  pharmaceutical  companies,  our  corporate  collaborators  or  others  selling  such  products.  If  our  current
products or any of our pipeline candidates during clinical trials were to cause adverse side effects, we may be exposed to substantial liabilities. In September
2018, two civil claims were brought in the District of Court of the central district in Israel which named our subsidiary SciVac Ltd. as a defendant. In one
claim,  two  minors,  through  their  parents,  allege  among  other  things,  defects  in  certain  batches  of  Sci-B-Vac  discovered  in  July  2015;  that  Sci-B-Vac  was
approved for use in children and infants in Israel without sufficient evidence establishing its safety; that SciVac Ltd failed to provide accurate information
about Sci-B-Vac to consumers and that each child suffered side effects from the vaccine. The claim was filed together with a motion seeking approval of a
class action on behalf of 428,000 children vaccinated with Sci-B-Vac in Israel since April 2011 and seeking damages in a total amount of NIS 1,879,500,000
(not in thousands) ($543.8 million). The second claim is a civil action brought by two minors and their parents against SciVac Ltd and IMoH alleging, among
other things, that SciVac Ltd. marketed an experimental, defective, hazardous or harmful vaccine; that Sci-B-Vac was marketed in Israel without establishing
its safety; and that Sci-B-Vac was produced and marketed in Israel without approval of a western regulatory body. The claim seeks damages for past and
future  losses  and  expenses  as  well  as  punitive  damages.  The  motion  seeking  approval  of  a  class  action  has  been  suspended  until  a  ruling  is  given  on  the
question  of  liability  in  the  civil  action.  The  preliminary  hearings  for  the  trial  of  the  civil  action  began  on  January  15,  2020.  Regardless  of  the  merits  or
eventual outcome, product liability claims or other claims related to our products or pipeline candidates may result in:

● decreased demand for our products due to negative public perception;

● injury to our reputation;

● withdrawal of clinical trial participants or difficulties in recruiting new trial participants;

● initiation of investigations by regulators;

● costs to defend or settle 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 any of our pipeline candidates, if approved.

We  currently  maintain  product  liability  insurance,  and  we  generally  obtain  clinical  trial  insurance  once  a  clinical  trial  is  initiated.  However,  the
insurance coverage may not be sufficient to reimburse us for any expenses or losses we may suffer. Insurance coverage is becoming increasingly expensive,
and, in the future, we, or any of our collaborators, may not be able to maintain insurance coverage at a reasonable cost or in sufficient amounts or at all to
protect us against losses due to liability. Even if our agreements with any current or future collaborators entitle us to indemnification against product liability
losses,  such  indemnification  may  not  be  available  or  adequate  should  any  claim  arise.  Our  inability  to  obtain  sufficient  product  liability  insurance  at  an
acceptable cost to protect against product liability claims could prevent or inhibit the commercialization of our pipeline candidates. If a successful product
liability claim or series of claims is brought against us for uninsured liabilities or in excess of insured liabilities, our assets may not be sufficient to cover such
claims and our business operations could be impaired.

Should  any  of  the  events  described  above  occur,  this  could  have  a  material  adverse  effect  on  our  business,  financial  condition  and  results  of

operations.

Even if we obtain regulatory approval for one or more of our pipeline candidates, we will still face extensive, ongoing regulatory requirements

and review, and our products may face future development and regulatory difficulties.

Even if we obtain regulatory approval for one or more of our pipeline candidates in the United States or other regions, which we cannot guarantee,
the FDA or other regulatory bodies may still impose significant restrictions on a product’s indicated uses or marketing or impose conditions for approval, or
impose  ongoing  requirements  for  potentially  costly  post-approval  studies,  including  Phase  IV  clinical  trials  or  post-market  surveillance.  As  a  condition  to
granting marketing approval of a product, the FDA or other regulatory bodies may require us to conduct additional clinical trials. The results generated in
these post-approval clinical trials could result in loss of marketing approval, changes in product labeling, or new or increased concerns about side effects or
efficacy of a product. For example, the labeling for our pipeline candidates, if approved, may include restrictions on use or warnings. The Food and Drug
Administration Amendments Act of 2007 gives the FDA enhanced post-market authority, including the explicit authority to require post-market studies and
clinical  trials,  labeling  changes  based  on  new  safety  information  and  compliance  with  FDA-approved  Risk  Evaluation  and  Mitigation  Strategies  (“REMS
programs”).  If  approved,  our  pipeline  candidates  will  also  be  subject  to  ongoing  FDA  requirements  governing  the  manufacturing,  labeling,  packaging,
storage,  distribution,  safety  surveillance,  advertising,  promotion,  record  keeping  and  reporting  of  safety  and  other  post-market  information.  The  FDA’s
exercise of its authority could result in delays or increased costs during product development, clinical trials and regulatory review, increased costs to comply
with additional post-approval regulatory requirements and potential restrictions on sales of approved products. Foreign regulatory agencies often have similar
authority and may impose comparable costs. Post-marketing studies, whether conducted by us or by others and whether mandated by regulatory agencies or
voluntary, and other emerging data about marketed products, such as adverse event reports, may also adversely affect sales of our pipeline candidates once
approved,  and  potentially  our  other  marketed  products.  Further,  the  discovery  of  significant  problems  with  a  product  similar  to  one  of  our  products  that
implicate (or are perceived to implicate) an entire class of products could have an adverse effect on sales of our approved products. Accordingly, new data
about our products could negatively affect demand because of real or perceived side effects or uncertainty regarding efficacy and, in some cases, could result
in  product  withdrawal  or  recall.  Furthermore,  new  data  and  information,  including  information  about  product  misuse,  may  lead  government  agencies,
professional societies and practice management groups or organizations involved with various diseases to publish guidelines or recommendations related to
the  use  of  our  products  or  the  use  of  related  therapies  or  place  restrictions  on  sales.  Such  guidelines  or  recommendations  may  lead  to  lower  sales  of  our
products.

The  holder  of  a  BLA  that  has  been  approved  also  is  subject  to  obligations  to  monitor  and  report  adverse  events  and  instances  of  the  failure  of  a
product to meet the specifications in the BLA. License holders must submit new or supplemental applications and obtain FDA approval for certain changes to
the approved product, product labeling, or manufacturing process. Application holders must also submit advertising and other promotional material to the
FDA. Advertising and promotional materials must comply with FDA rules in addition to other potentially applicable federal and state laws, including, by way
of example, the Federal Trade Commission Act. Any sales and promotional activities are also potentially subject to federal and state consumer protection and
unfair competition laws. The FDA and other regulatory agencies strictly regulate the promotional claims that may be made about prescription products. In
particular, a product may not be promoted for uses that are not approved by the FDA, or such other regulatory agencies as reflected in the product’s approved
labeling. In particular, any labeling approved by such regulatory agencies for our pipeline candidates may also include restrictions on use. Such regulatory
agencies may impose further requirements or restrictions on the distribution or use of our pipeline candidates as part of a mandatory plan, such as limiting
prescribing to certain physicians or medical centers that have undergone specialized training, limiting treatment to patients who meet certain safe-use criteria
and requiring treated patients to enroll in a registry. If we receive marketing approval for one or more of our pipeline candidates, physicians may nevertheless
prescribe such products to their patients in a manner that is inconsistent with the approved label. If we are found to have promoted such off-label uses, we
may become subject to significant liability. In particular, the United States federal government has levied large civil and criminal fines against companies for
alleged improper promotion and has enjoined several companies from engaging in off-label promotion. The FDA has also requested that companies enter into
consent decrees or permanent injunctions under which specified promotional conduct is changed or curtailed.

27

 
 
 
 
 
 
 
Depending on the circumstances, failure to meet post-approval requirements by us or our third-party collaborators can result in criminal prosecution,
fines or other penalties, injunctions, recall or seizure of products, total or partial suspension of production, denial or withdrawal of pre-marketing product
approvals, FDA issuance of Form 483, untitled letters, and/or warning letters, suspension or termination of any ongoing clinical trials, or refusal to allow us to
enter into supply contracts, including government contracts. Any government investigation of alleged violations of law could require us to expend significant
amounts of time and resources in response, and could generate negative publicity and significantly inhibit our ability to bring to market or continue to market
our products and generate revenue.

We may seek to in-license pipeline candidates or technologies to expand our product pipeline and may not succeed.

If and when we deem it to be our strategic priority, we may seek to in-license pipeline candidates or technologies to expand our product pipeline and
may not succeed. The number of such candidates and technologies is limited. Competition among large pharmaceutical companies and biopharmaceutical
companies for promising pipeline candidates and technologies is intense because such companies generally desire to expand their product pipelines through
in-licensing.  If  we  fail  to  carry  out  such  in-licensing  and  expand  our  product  pipeline,  our  potential  future  revenues  may  suffer  especially  if  our  current
products or pipeline candidates fail to generate material revenue.

The  failure  by  us  or  our  current  or  future  manufacturers  to  obtain  FDA  or  other  regulatory  agencies’  approval  for  manufacturing  facilities

could have a material adverse impact on our business, results of operations, financial condition and prospects.

Our  manufacturing  facilities  and  any  of  our  current  and  future  contract  manufacturers,  whether  the  facilities  are  ours  or  third-party  manufacturer
facilities, must be inspected by the FDA, after we submit a BLA and before approval, or by the regulators in other jurisdictions for our pipeline candidates to
be  manufactured  for  commercial  production.  In  the  event  that  we  are  approved  to  market  a  drug  product  in  the  United  States,  we  or  our  third-party
manufacturers must register the manufacturing facilities with the FDA and are subject to continual review and periodic inspections by the FDA and other
regulatory authorities for compliance with the FDA’s current Good Manufacturing Practices regulations. Similar rules apply in the event we are approved to
market  a  medicinal  product  in  the  European  Union.  Other  than  Sci-B-Vac,  which  is  currently  manufactured  by  us,  we  are  completely  dependent  on  these
third-party  manufacturers  for  compliance  with  the  requirements  of  United  States  and  non-United  States  regulators  for  the  manufacture  of  our  finished
products. If we or our third-party manufacturers cannot successfully produce material that conforms to our specifications and current good manufacturing
practice  requirements  of  any  applicable  regulatory  agency,  we  will  not  be  able  to  secure  approval  for  our  manufacturing  facilities.  If  the  FDA  or  another
regulatory agency does not approve these facilities for commercial production, we will need to find alternative suppliers, which would result in significant
delays in obtaining required regulatory approvals. In addition, if we or a regulatory agency discover previously unknown problems with a product, such as
adverse  events  of  unanticipated  severity  or  frequency  or  problems  with  the  facility  where  the  product  is  manufactured,  a  regulatory  agency  may  impose
restrictions  on  that  product,  the  manufacturing  facility,  or  us,  including  requiring  recall  or  withdrawal  of  the  product  from  the  market  or  suspension  of
manufacturing, requiring new warnings or other labeling changes to limit use of the drug, requiring that we conduct additional clinical trials, imposing new
monitoring requirements or requiring that we establish a REMS program. These challenges may have a material adverse impact on our business, results of
operations, financial condition and prospects.

28

 
 
 
 
 
 
 
We  manufacture  clinical  and  commercial  supplies  of  Sci-B-Vac  at  a  single  location.  Any  disruption  in  the  operations  of  our  manufacturing

facility could adversely affect our business and results of operations.

We  rely  on  our  manufacturing  facility  in  Rehovot,  Israel,  for  the  manufacture  of  all  clinical  and  commercial  supplies  of  Sci-B-Vac  and  clinical
supplies of VBI-2601. Our current manufacturing facility contains highly specialized equipment and materials and utilizes complicated production processes
developed over a number of years, which would be difficult, time-consuming and costly to duplicate or, though a remote risk, may be impossible to duplicate.
If our facility were damaged or destroyed, or otherwise subject to disruption, including contamination, it would require substantial lead-time to replace our
manufacturing capabilities and could cause costly delays. In such event, we would be forced to identify and rely entirely on third-party contract manufacturers
for an indefinite period of time, which we may not be able to do in a timely manner and would further increase our production costs. Any disruptions or
delays at our facility or its failure to meet regulatory compliance would significantly impair our ability to manufacture Sci-B-Vac for sale in the jurisdictions
where it is approved for sale and for our ongoing and future clinical studies of VBI-2601 and for future clinical studies of Sci-B-Vac, if required, where we
seek regulatory approval, which would result in increased costs and losses and adversely affect our business and results of operations.

We incurred significant costs to modernize and increase the capacity of our manufacturing facility in Rehovot, Israel. Any delays in validating
the  modernization  and  capacity  increase  of  our  facility  could  adversely  affect  our  ability  to  supply  our  vaccines  for  commercial  sale  and  clinical
development.

We  invested  substantial  funds  to  modernize  and  increase  the  capacity  of  our  manufacturing  facility  in  Rehovot,  Israel,  where  we  manufacture  all
clinical and commercial supplies of Sci-B-Vac and clinical materials of VBI-2601. During the modernization and capacity increase, which started in April
2018, we ceased manufacturing operations at our manufacturing facility. Although the modernization and the capacity increase of our manufacturing facility
has been completed and we obtained a certificate of GMP compliance from the IMoH on January 27, 2020, the IMoH will also need to review and approve
the process validation submission and provide approval for us to sell Sci-B-Vac manufactured at the modernized facility. If we are unable to promptly obtain
IMoH approval, our ability to commercially sell Sci-B-Vac could be interrupted, the costs associated with our modernization project would increase, and our
sales of Sci-B-Vac and the timing of our clinical studies related to VBI-2601 could be adversely affected.

If a supplier of our raw materials and certain reagents fails to provide sufficient quantities to us, we may not be able to obtain an alternative

supply on a timely or acceptable basis.

We rely on a single source for our supply of some of our raw materials and certain reagents required for the manufacture of Sci-B-Vac and VBI-
2601. We do not have a written or oral agreement with these single sources of supply, as all orders are handled through individual purchase orders or on an
order-by-order  basis.  Alternative  sources  from  which  we  can  obtain  our  supply  of  most  of  these  materials  exist.  However,  we  may  not  be  able  to  find
alternative  suppliers  in  a  timely  manner  that  would  provide  supplies  of  these  raw  materials  or  reagents  at  acceptable  quantities  and  prices,  if  at  all.  Any
interruption  in  the  supply  of  these  materials  would  disrupt  our  ability  to  manufacture  Sci-B-Vac  or  VBI-2601  for  further  development,  current  and  future
clinical trials, and commercial manufacturing, and could have a material adverse effect on our business, commercialization of Sci-B-Vac and VBI-2601 and
future profit margins, if any.

We do not manufacture any of our raw materials nor do we plan to develop any capacity to do so. Instead, we rely on multiple sources to supply our
raw materials so that we can manufacture sufficient quantities of Sci-B-Vac and VBI-2601 at our manufacturing facility. Some of the countries of origin of
our raw materials are not the same as our drug manufacturing location. Any disruption in supply of raw materials from a qualified supplier could result in
significant delays with our manufacturing, clinical trials, BLA filing, BLA approval or commercial sale of the finished product due to contract delays, the
need to manufacture new raw materials, out of specification raw materials, the need for import and export permits, and the failure of the newly sourced raw
materials to perform to the standards of the previously sourced raw materials. These delays could have a material adverse effect on our business and future
profit margins, if any.

29

 
 
 
 
 
 
 
 
 
We  expect  the  healthcare  industry  to  face  increased  limitations  on  reimbursement,  rebates  and  other  payments  as  a  result  of  continued
healthcare reform changes, which could adversely affect third-party coverage of our products and how much or under what circumstances healthcare
providers will prescribe or administer our products.

In  both  the  United  States  and  other  countries,  sales  of  our  products  will  depend  in  part  upon  the  availability  of  reimbursement  from  third-party
payers, which include governmental authorities, managed care organizations and other private health insurers. Third-party payers are increasingly challenging
the price and examining the cost effectiveness of medical products and services.

Increasing  expenditures  for  healthcare  have  been  the  subject  of  considerable  public  attention  in  the  United  States.  Both  private  and  government
entities are seeking ways to reduce or contain healthcare costs. Numerous proposals that would effect changes in the United States healthcare system have
been introduced or proposed in Congress and in some state legislatures, including reducing reimbursement for prescription products and reducing the levels at
which consumers and healthcare providers are reimbursed for purchases of pharmaceutical products.

Cost reduction initiatives and changes in coverage implemented through legislation or regulation could decrease utilization of and reimbursement for
any  approved  products,  which  in  turn  would  affect  the  price  we  can  receive  for  those  products.  Any  reduction  in  reimbursement  that  results  from  federal
legislation  or  regulation  may  also  result  in  a  similar  reduction  in  payments  from  payers.  New  laws  may  also  result  in  additional  reductions  in  healthcare
funding, which could have a material adverse effect on our customers, which may affect our financial operations. Legislative and regulatory proposals may
expand  post-approval  requirements  and  restrict  sales  and  promotional  activities  for  pharmaceutical  products.  We  cannot  be  certain  whether  additional
legislative changes will be enacted, or whether relevant regulations, guidance, or interpretations will be changed, or what the impact of such changes on our
products may be.

Although we cannot predict the full effect on our business of the implementation of existing legislation or the enactment of additional legislation
pursuant to healthcare and other legislative reform, we believe that legislation or regulations that would reduce reimbursement for, or restrict coverage of, our
products could adversely affect how much or under what circumstances healthcare providers will prescribe or administer our products. This could materially
and  adversely  affect  our  business  by  reducing  our  ability  to  generate  revenue,  raise  capital,  obtain  additional  collaborators  and  market  our  products.  In
addition,  we  believe  the  increasing  emphasis  on  managed  care  in  the  United  States  has  and  will  continue  to  put  pressure  on  the  price  and  usage  of
pharmaceutical products, which may adversely impact product sales.

Governments outside the United States tend to impose strict price controls, which may adversely affect our future revenues.

In  some  countries,  particularly  countries  in  Europe,  the  pricing  and/or  reimbursement  of  prescription  pharmaceuticals  is  subject  to  governmental
control. In Canada, the prices of patented medicines are subject to price controls. In these countries, pricing negotiations with governmental authorities can
take  considerable  time  after  the  receipt  of  marketing  approval  for  a  product.  To  obtain  reimbursement  or  pricing  approval  in  some  countries,  we  may  be
required to conduct a study that compares the cost-effectiveness of our products to other available therapies. If reimbursement of our products is unavailable
or limited in scope or amount, or if pricing is set at unsatisfactory levels, our business could be harmed, possibly materially.

30

 
 
 
 
 
 
 
 
 
We face intense competition and rapid technological change, which may make it more difficult to achieve significant market penetration. If we
cannot compete successfully for market share against other drug companies, we may not achieve sufficient product revenues and our business will suffer.

The market for our pipeline candidates is characterized by intense competition and rapid technological advances. For example, if it is approved in the
future, Sci-B-Vac will compete in the United States with approved hepatitis B virus vaccines marketed by GSK, Dynavax, and Merck and compete outside the
United  States  with  vaccines  from  GSK,  Merck,  and  several  additional  established  pharmaceutical  companies.  If  competitors’  existing  products  or  new
products  are  more  effective  than  or  considered  superior  to  our  current  or  future  products,  the  commercial  opportunity  for  our  products  will  be  reduced  or
eliminated. Existing or future competing products may provide greater therapeutic convenience or clinical or other benefits for a specific indication than our
products or may offer comparable performance at a lower cost. We face competition from 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 our competitors have products or pipeline candidates already approved or in development. In addition, many of these competitors, either alone or
together  with  their  collaborative  partners,  are  larger  than  us  and  have  substantially  greater  financial,  technical,  research,  marketing,  sales,  distribution  and
other resources. Existing and potential competitors may develop or market products that are more effective or commercially attractive than any that we are
developing or marketing. Competitors may obtain regulatory approvals and introduce and commercialize products before we do. These developments could
have a significant negative effect on our financial condition. Even if we are able to compete successfully, we may not be able to do so in a profitable manner.

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

Our  research  and  development  activities  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,  provincial  and  local  laws  and  regulations,  we  cannot
completely 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.  In  addition,  the  federal,
provincial,  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 adversely affect our business and financial condition.

Our pipeline candidates may never achieve market acceptance, even if we obtain regulatory approvals.

Even if we receive regulatory approvals for the commercial sale of our pipeline candidates, the commercial success of these pipeline candidates will
depend on, among other things, their acceptance by physicians, patients, third-party payers such as health insurance companies and other members of the
medical community as a vaccine and a cost-effective alternative to competing products. If our pipeline candidates fail to gain market acceptance, we may be
unable to earn sufficient revenue to continue our business. Market acceptance of, and demand for, any product that we may develop and commercialize will
depend on many factors, including:

● our ability to provide acceptable evidence of safety and efficacy;

● the prevalence and severity of adverse side effects;

● whether our vaccines are differentiated from other vaccines based on immunogenicity;

● availability, relative cost and relative efficacy of alternative and competing treatments;

● the effectiveness of our marketing and distribution strategy;

● publicity concerning our products or competing products and treatments; and

● our ability to obtain sufficient third-party insurance coverage or reimbursement.

In particular, there are significant challenges to obtaining regulatory approval for CMV vaccine candidates developed for a target market (i.e. pre-
pregnant women) due to the relatively low tolerance for risk to these populations. The risk-benefit analysis undertaken by the FDA and other regulators in
deciding whether or not to approve this product candidate will be high relative to other vaccines and biologic products that target less sensitive populations.

If our pipeline candidates do not become widely accepted by physicians, patients, third-party payers and other members of the medical community,

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

If  we  are  unable  to  manufacture  our  eVLP  pipeline  candidates  in  sufficient  quantities,  at  sufficient  yields  or  are  unable  to  obtain  regulatory
approvals  for  a  manufacturing  facility  for  our  vaccines,  we  may  experience  delays  in  product  development,  clinical  trials,  regulatory  approval  and
commercial distribution.

Completion  of  our  clinical  trials  and  commercialization  of  our  eVLP  pipeline  candidates  require  access  to,  or  development  of,  facilities  to
manufacture our eVLP pipeline candidates at sufficient yields and at commercial-scale. We have limited experience manufacturing any of our eVLP pipeline
candidates in the volumes that will be necessary to support large-scale clinical trials or commercial sales. Efforts to establish these capabilities may not meet
initial expectations as to scheduling, scale-up, reproducibility, yield, purity, cost, potency or quality.

If  we  are  unable  to  manufacture  our  eVLP  pipeline  candidates  in  clinical  or  commercial  quantities,  as  the  case  may  be,  in  sufficient  yields,  with
sufficient purity, potency, quality, and identity, then we must find, qualify, and rely on third parties. Any new third-party manufacturers must also receive
FDA approval before we may use product manufactured by them as our commercial products and pipeline candidates. Our products may be in competition
with  other  products  for  access  to  these  facilities  and  may  be  subject  to  delays  in  manufacture  if  our  third-party  manufacturers  give  other  products  greater
priority. Any delays experienced by third-party manufacturers, whether directly or by its raw material suppliers in relation to our project, may result in delays
in clinical development of our eVLP pipeline candidates.

As a result, any delay or interruption could have a material adverse effect on our business, financial condition, results of operations and cash flows.

In light of our current resources and limited commercial experience, we may need to establish successful third-party relationships to successfully

commercialize our pipeline candidates.

The near and long-term viability of our pipeline candidates may depend, in part, on our ability to successfully establish new strategic collaborations
with pharmaceutical and biotechnology companies, non-profit organizations and government agencies. Establishing and maintaining strategic collaborations
and  obtaining  government  funding  is  difficult  and  time-consuming.  Potential  collaborators  may  reject  collaborations  based  upon  their  assessment  of  our
financial, regulatory or intellectual property position or based on their internal pipeline; government agencies may reject contract or grant applications based
on their assessment of public need, the public interest, the ability of our products to address these areas, or other reasons beyond our expectations or control.
If we fail to establish or maintain a sufficient number of collaborations or government relationships on acceptable terms, we may not be able to commercialize
our pipeline candidates or generate sufficient revenue to fund further research and development efforts.

Even  if  we  establish  new  collaborations  or  obtain  government  funding,  these  relationships,  including  our  collaboration  with  Brii  Bio,  may  never

result in the successful development or commercialization of any pipeline candidates for several reasons, including the fact that:

● we may not have the ability to control the activities of our partners and cannot provide assurance that they will fulfill their obligations  to  us,

including with respect to the license, development and commercialization of pipeline candidates, in a timely manner or at all;

● such partners may not devote sufficient resources to our pipeline candidates or properly maintain or defend our intellectual property rights;

● relationships with our collaborators could also be subject to certain fraud and abuse laws if not structured properly to comply with such laws;

● any failure on the part of our partners to perform or satisfy their obligations to us could lead to delays in the development or commercialization

of our pipeline candidates and affect our ability to realize product revenue; and

● disagreements, including disputes over the ownership of technology developed with such collaborators, could result in litigation, which would
be time-consuming and expensive, and may delay or terminate research and development efforts, regulatory approvals and commercialization
activities.

If we or our collaborators fail to maintain our existing agreements or in the event we fail to establish agreements as necessary, we could be required
to undertake research, development, manufacturing and commercialization activities solely at our own expense. These activities would significantly increase
our  capital  requirements  and,  given  our  lack  of  sales,  marketing  and  distribution  capabilities,  significantly  delay  the  commercialization  of  our  pipeline
candidates.

Our marketing, promotional and business practices, including those that occur prior to the FDA’s or another regulatory authority’s approval of a

product candidate, are subject to extensive regulation and any material failure to comply could result in significant sanctions against us.

The marketing, promotional, and business practices of pharmaceutical and biologics companies are subject to extensive regulation, the enforcement

of which may result in the imposition of civil and/or criminal penalties, injunctions, and/or limitations on marketing practices for some of our products.

There is no official FDA definition of “promotion,” but FDA regulations, guidance documents, and enforcement actions make clear that the FDA
takes  a  broad  view  of  the  term.  Promotional  materials  include  any  written,  oral,  graphic,  or  broadcast  material  made  and  distributed  to  consumers  by  a
company or its agents with the intent to proactively communicate certain attributes (e.g., use/indication, safety, effectiveness, etc.) of a given drug or biologic
product. Examples include presentations, posters, brochures, notes, e-mail messages (external), blog postings, corporate websites, social media posts, videos,
oral representations made by company representatives, product samples, reprints of scientific and medical articles, among others. To be lawful, promotions, at
a minimum, must:

● be consistent with, and not contrary to, labeling;

● present “fair balance” between risks and benefits;

● be truthful and not false or misleading;

● be adequately substantiated (when required); and

● include adequate directions for use.

Aside from off-label promotion, a lack of fair balance between risk information and benefit information has become the highest enforcement priority
for the FDA in this context. We may also be subject to enforcement action in connection with any promotion of an investigational product. Under the Food,
Drug and Cosmetic Act, a sponsor or investigator, or any person acting on behalf of a sponsor or investigator, shall not represent in a promotional context that
an investigational new drug is safe or effective for the purposes for which it is under investigation or otherwise promote the product candidate. The most
common factors that trigger FDA enforcement actions for unauthorized promotion of an investigational drug include:

● Absence of clear and prominent statement on investigational status;

● Use of trade name pre-approval (without adequate clarification as to status);

● Lack of separation between information on investigational and approved products;

● Characterizations  and  descriptions  of  a  promotional  nature  that  are  phrased  as  established  facts  (e.g.,  “long  actions,”  “tamper-resistant,”  “next

generation”); and

● Presentation of information in a manner that visually suggests it is an approved product (e.g., under a heading titled “Products”).

Any enforcement action or lawsuit brought against us in connection with alleged violations of applicable promotion requirements, or prohibitions,

could harm our business and our reputation, as well as the reputation of any then approved products we may promote or commercialize.

We may be subject to additional risks due to the involvement of third-party drugs, devices, or other products in clinical studies evaluating the
safety  and/or  efficacy  of  our  pipeline  candidates  and/or  in  connection  with  the  commercial  use  of  any  such  candidates  approved  by  the  FDA  for
marketing in the United States in the future.

One or more existing FDA-approved therapies may be involved in the clinical testing of a given product candidate, as such product candidate may be
tested  in  combination  with  a  therapy  developed  by  another  company  or  administered  using  a  third-party  medical  device.  For  example,  our  vaccine
immunotherapeutic  candidate  VBI-1901  is  administered  in  conjunction  with  two  existing  adjuvant  therapies  via  intradermal  injection.  Accordingly,  our
clinical  studies  for  VBI-1901,  and  any  other  study  involving  a  third-party  product,  may  subject  us  to  additional  risks  that  we  may  not  otherwise  face  in
connection with studies conducted without third-party products.

Among other potential risks, a third-party product we utilize could be defective, removed from the market, or otherwise rendered unavailable for the
applicable use. Additionally, the safety and/or efficacy of such products may be called into question for reasons beyond our control, including, but not limited
to, serious adverse events associated with the product; regulatory enforcement action against the product’s manufacturer, developer, or other responsible party,
as  applicable;  or  any  other  circumstance  or  finding  that  negatively  impacts  the  perceived  utility  or  reliability  of  the  product.  The  occurrence  of  any  such
events in connection with a third-party drug, device, or other product used in our clinical studies could cause the FDA and/or industry to question the validity
of our clinical trial data or improperly attribute safety or efficacy issues to our pipeline candidates, either of which could have a material adverse effect on our
ability to successfully develop and commercialize such candidates. We cannot predict the ultimate impact that any third-party product used in our clinical
studies may have on our business, as such is dependent upon a number of factors outside of our reasonable control.

Risks Related to Our Capital Requirements and Financings

We will need additional financing to continue our operations. If we are unable to obtain additional financing on acceptable terms, we may have

to curtail or cease our development plans and operations.

Our revenue generating activities include product sales and research and development services pursuant to fee for service agreements, collaboration
agreements and certain governmental research and development grants. However, our revenues have not been significant to date. Our long-term success and
ability to continue as a going concern is dependent upon obtaining sufficient capital to fund the research and development of our products, to bring about their
successful  commercial  release,  if  approved,  to  generate  revenue  and,  ultimately,  to  attain  profitable  operations  or  alternatively  advance  the  products  and
technology to such a point that an acquirer would find attractive. We face substantial demand on our cash resources to fund operations and our growth plans
in the future.

To date, we have been able to obtain financing; however, there is no assurance that financing will be available in the future, or if it is, that it will be
available  at  terms  acceptable  to  us.  Additional  financings  may  be  effected  through  debt  financing  and/or  the  issuance  of  equity  securities,  there  being  no
assurance that any type of financing on terms acceptable to us will be available or otherwise occur. Debt financing must be repaid regardless of whether we
generate revenues or cash flows from operations and may be secured by substantially all of our assets. Any equity financing or debt financing that requires the
issuance of equity securities or securities convertible into equity securities would cause the percentage ownership of our shareholders to be diluted, which
dilution may be substantial. Also, any additional equity securities issued may have rights, preferences or privileges senior to those of existing shareholders.
Furthermore,  if  we  issue  additional  securities,  whether  equity  or  debt,  or  if  investors  believe  we  may  issue  additional  securities,  the  market  price  of  our
common  shares  could  decline.  If  such  financing  is  not  available  when  required  or  is  not  available  on  acceptable  terms,  we  may  be  required  to  reduce  or
eliminate certain pipeline candidates and development activities, and it may ultimately require us to suspend or cease operations, which could cause investors
to lose the entire amount of their investment.

34

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

We have incurred significant net losses and negative operating cash flows since inception. We incurred net losses of approximately $55 million and
$64 million in 2019 and 2018, respectively. As of December 31, 2019, we had an accumulated deficit of $262 million. Our income generating activities have
been from sales of our Sci-B-Vac product in markets that have generated a limited number of sales to-date, fees from research and development services and
revenue  from  partnership  collaborations.  We  expect  to  incur  significant  operating  losses  for  the  next  several  years  as  we  support  Sci-B-Vac  regulatory
submissions  and  pre-commercialization  activities,  expand  our  research  and  development,  advance  other  pipeline  candidates  into  and  through  clinical
development,  including  our  immunotherapeutic  hepatitis  B  candidate,  CMV  candidate  and  GBM  vaccine  immunotherapeutic  candidate,  complete  clinical
trials  and  seek  regulatory  approval.  Because  of  the  numerous  risks  and  uncertainties  associated  with  developing  and  commercializing  pharmaceutical
products, as well as those related to our expectations for the Brii License Agreement, we are unable to predict the extent of any future losses or guarantee
when, or if, our company will become profitable or cash flow positive. If we never achieve profitability or positive cash flows, or achieve either later than we
anticipate, you may lose some or all of your investment in us.

Our  financial  statements  have  been  prepared  on  a  going  concern  basis;  we  must  raise  additional  capital  to  fund  our  operations  in  order  to

continue as a going concern.

In  its  report  dated  March  5,  2020,  EisnerAmper  LLP,  our  independent  registered  public  accounting  firm,  expressed  substantial  doubt  about  our
ability to continue as a going concern as we have suffered recurring losses from operations and have insufficient liquidity to fund our future operations. If we
are unable to improve our liquidity position we may not be able to continue as a going concern. The accompanying consolidated financial statements do not
include any adjustments that might result if we are unable to continue as a going concern and, therefore, be required to realize our assets and discharge out
liabilities other than in the normal course of business which could cause investors to suffer the loss of all or a substantial portion of their investment. As of
December 31, 2019, we had $44.2 million of cash. In order to have sufficient cash to fund our operations in the future, we will need to raise additional equity
or debt capital and cannot provide any assurance that we will be successful in doing so.

Risks Related to Our Business

Adverse effects resulting from other immunotherapy drugs or therapies could also negatively affect the perceptions by members of the health

care community, including physicians, about the safety and effectiveness of our pipeline candidates.

There are many other companies that have developed or are currently trying to develop immuno-oncology products for the treatment of cancer. If
adverse effects were to result from any immunotherapy drugs or therapies being developed, manufactured and marketed by others it could be attributed to our
products or immunotherapy protocols as a whole. In fact, in the past biologics have been associated with certain safety risks and other companies developing
biologics  have  had  patients  in  trials  suffer  from  serious  adverse  events,  including  death.  Any  such  attribution  could  negatively  affect  the  perceptions  by
members of the health care community, including physicians, about the safety and effectiveness of our pipeline candidates and the future of immunotherapy
for the treatment of cancer. Our industry is susceptible to rapid technological changes and there can be no assurance that we will be able to overcome any new
technological challenges presented by the adverse effects resulting from immunotherapy drugs or therapies developed, manufactured or marketed by others.

We have international operations, which subject us to risks inherent with operations outside of Canada.

We have international operations and we may seek to obtain market approvals in foreign markets that we deem to generate significant opportunities.
However, even with the cooperation of a commercialization partner, conducting drug development in foreign countries involves inherent risks, including, but
not  limited  to:  difficulties  in  staffing,  funding  and  managing  foreign  operations;  different  and  unexpected  changes  in  regulatory  requirements;  export
restrictions; tariffs and other trade barriers; different reimbursement systems; economic weaknesses or political instability in particular foreign economies and
markets;  compliance  with  tax,  employment,  immigration  and  labor  laws  for  employees  living  or  travelling  abroad;  supply  chain  and  raw  materials
management; difficulties in protecting, acquiring, enforcing and litigating intellectual property rights; fluctuations in currency exchange rates; and potentially
adverse tax consequences.

35

 
 
 
 
 
 
 
 
 
 
 
If  we  were  to  experience  any  of  the  difficulties  listed  above,  or  any  other  difficulties,  our  international  development  activities  and  our  overall

financial condition may suffer and cause us to reduce or discontinue our international development and market approval efforts.

We may not be successful in hiring and retaining key employees, in which case our business may be harmed.

Our business is highly dependent upon the continued services of our senior management and key scientific and technical personnel. As such, our
future  success  depends  on  our  ability  to  identify,  attract,  hire  or  engage,  retain  and  motivate  well-qualified  managerial,  technical,  clinical  and  regulatory
personnel.  Our  operations  require  qualified  personnel  with  expertise  in  nonclinical  pharmacology  and  toxicology,  pharmaceutical  development,  clinical
research,  regulatory  affairs,  manufacturing,  sales  and  marketing.  We  must  compete  for  qualified  individuals  with  numerous  biopharmaceutical  companies,
universities and other research institutions. Competition for such individuals is intense, and, when the need arises, we may not be able to hire the personnel
necessary to support our efforts. There can be no assurance that these professionals will be available in the market, or that we will be able to retain existing
professionals or to meet or to continue to meet their compensation requirements. Furthermore, the cost base in relation to such compensation, which may
include  equity  compensation,  may  increase  significantly,  which  could  have  a  material  adverse  effect  on  us.  Failure  to  establish  and  maintain  an  effective
management team and work force could adversely affect our ability to operate, grow and manage our business.

Our employees may engage in misconduct or other improper activities, including noncompliance with regulatory standards and requirements.

We are exposed to the risk of employee fraud or other misconduct. Misconduct by employees could include intentional failures to:

● comply with FDA regulations or similar regulations of comparable foreign regulatory authorities;

● provide accurate information to the FDA or comparable foreign regulatory authorities;

● comply with manufacturing standards that we have established;

● comply with  federal  and  state  healthcare  fraud  and  abuse  laws  and  regulations  and  similar  laws  and  regulations  established  and  enforced  by

comparable foreign regulatory authorities;

● properly protect patient information which is subject to federal and state privacy and security laws or similar laws in foreign countries;

● 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 commissions, 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. It is not always possible
to identify and deter employee misconduct, and the precautions that 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 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  to  federal,  provincial  and  state  healthcare  laws,  regulations,  and  policies  in  connection  with  our  current  and/or  future

activities and our failure to comply with those laws could have a material adverse effect on our results of operations and financial conditions.

In addition to FDA restrictions on marketing and other applicable regulations, if we obtain FDA approval to commercialize any of our current or
future product candidates in the United States, our operations may be directly, or indirectly, through our relationships with healthcare providers, customers
and third-party payors, subject to various federal and state fraud and abuse laws, including, without limitation the following:

● the federal Anti-Kickback Statute (and state equivalents), which prohibits, among other things, persons from knowingly and willfully soliciting,
receiving,  offering  or  paying  remuneration,  directly  or  indirectly,  in  exchange  for  or  to  induce  either  the  referral  of  an  individual,  or  the
furnishing, arranging for, or the purchase, order or recommendation of, any item or service that is reimbursable, in whole or in part, by a federal
healthcare program such as the Medicare and Medicaid programs;

● the federal physician self-referral law, commonly known as the “Stark Law” (and state equivalents), which prohibits a physician from making a
referral for certain designated health services covered by the Medicare program if the physician or an immediate family member has a financial
relationship with the entity providing the designated health services, unless the financial relationship falls within an applicable exception to the
prohibition;

● the federal False Claims Act and related laws (and state equivalents) that prohibit and impose liability on any person or entity that, among other

things, knowingly presents, or causes to be presented, a false or fraudulent claim for payment to the federal government;

● the so-called qui tam provisions of the federal and state False Claims Act, which permit whistleblowers to sue in the name of the federal or state
governments’  healthcare  providers  and  others  for  alleged  violations  of  those  laws  and  which  permit  whistleblowers  to  obtain  a  reward  for
bringing the case. These qui tam cases have been on the rise in recent years;

● federal  criminal  laws  that  prohibit  executing  a  scheme  to  defraud  any  healthcare  benefit  program  or  making  false  statements  relating  to

healthcare matters;

● the federal transparency requirements under the Affordable Care Act, including the provisions commonly referred to as the Physician Payments
Sunshine  Act,  which  requires  certain  manufacturers  of  drugs,  devices,  biologics  and  medical  supplies  that  are  reimbursable  under  Medicare,
Medicaid or Children’s Health Insurance Program to report annually to the Centers for Medicare & Medicaid Services information related to
payments and other transfers of value to physicians and teaching hospitals, and ownership and investment interests held by physicians and their
immediate family members;

 ● the federal Civil Monetary Penalties Law, which prohibits, among other things, the offering or transfer of remuneration to a Medicare or state
healthcare program beneficiary if the person knows or should know it is likely to influence the beneficiary’s selection of a particular provider,
practitioner, or supplier of services reimbursable by Medicare or a state healthcare program, unless an exception applies;

● the Prescription Drug Marketing Act, as amended, which governs the distribution of prescription drug samples to healthcare practitioners;

● the  fraud  and  abuse  provisions  of  the  federal  Health  Insurance  Portability  and  Accountability  Act  of  1996,  as  amended  by  the  Health
Information Technology for Economic and Clinical Health Act (“HITECH”), and its implementing regulations (collectively “HIPAA”), which
imposes  criminal  and  civil  liability  for  executing  a  scheme  to  defraud  any  healthcare  benefit  program  or  making  false  statements  relating  to
healthcare matters and established comprehensive federal standards with respect to the privacy and security of protected health information and
requirements for the use of certain standardized electronic transactions, and amendments made in 2013 to HIPAA under the Health Information
Technology  for  Economic  and  Clinical  Health  Act,  which  strengthens  and  expands  HIPAA  privacy  and  security  compliance  requirements,
increases penalties for violators, extends enforcement authority to state attorneys general, and imposes requirements for breach notification;

● analogous state laws and regulations, including (among others) state anti-kickback, self-referral, and false claims laws, which may apply to our
business practices, including, but not limited to, research, distribution, sales and marketing arrangements and claims involving healthcare items
or services reimbursed by any third-party payor, including private insurers; state laws that require pharmaceutical companies to comply with the
pharmaceutical  industry’s  voluntary  compliance  guidelines  and  the  relevant  compliance  guidance  promulgated  by  the  United  States  federal
government,  or  otherwise  restrict  payments  that  may  be  made  to  healthcare  providers  and  other  potential  referral  sources;  state  laws  and
regulations that require drug manufacturers to file reports relating to pricing and marketing information and that require tracking gifts and other
remuneration  and  items  of  value  provided  to  healthcare  professionals  and  entities;  state  and  local  laws  that  require  the  registration  of
pharmaceutical sales representatives; and

● state and local law equivalents of HIPAA related to the privacy and security of patient information in certain circumstances, which are typically
not preempted by HIPAA and may apply more broadly, and/or contain different, potentially more stringent, restrictions and obligations, than
HIPAA thus complicating compliance efforts.

Further,  the  Affordable  Care  Act,  among  other  things,  amended  the  intent  requirement  of  the  federal  anti-kickback  and  criminal  healthcare  fraud
statutes. A person or entity can be found guilty of fraud or false claims under the Affordable Care Act without actual knowledge of the statute or specific
intent to violate it. In addition, the Affordable Care Act provides that 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 false claims statutes. Ensuring that our future business
arrangements with third parties comply with applicable healthcare laws and regulations could involve substantial costs. Possible sanctions for violation of the
applicable  fraud-and-abuse  laws  may  include  monetary  fines,  civil  and  criminal  penalties,  exclusion  from  Medicare,  Medicaid  and  other  government
programs,  forfeiture  of  amounts  collected  in  violation  of  such  prohibitions,  individual  imprisonment,  additional  reporting  obligations  and  oversight  (if  we
become  subject  to  a  corporate  integrity  agreement  or  other  agreement  to  resolve  allegations  of  non-compliance  with  these  laws),  and  the  curtailment  or
restructuring of our operations. Any violations of these laws, or any action against us for violation of these laws, even if we successfully defend against such
claims, could result in a material adverse effect on our reputation, business, results of operations and financial condition. In addition, there has been a recent
trend  of  increased  federal  and  state  regulation  of  payments  made  to  physicians  and  teaching  hospitals  for  marketing,  medical  directorships,  and  other
purposes. Some states impose a legal obligation on companies to adhere to voluntary industry codes of behavior (e.g., the PhRMA Code and the AdvaMed
Code  of  Ethics),  which  apply  to  pharmaceutical  and  medical  device  companies’  interactions  with  healthcare  providers;  some  mandate  implementation  of
corporate compliance programs, along with the tracking and reporting of gifts, compensation and other remuneration to physicians, and some states limit or
prohibit such gifts.

Most recently, there has been a trend in federal and state legislation aimed at requiring pharmaceutical companies to disclose information about their
production and marketing costs, and ultimately lowering costs for drug products. Several states have passed or introduced bills that would require disclosure
of certain pricing information for prescription drugs that have no threshold amount or are above a certain annual wholesale acquisition cost. In June 2016,
Vermont became the first state to pass legislation requiring certain drug companies to disclose information relating to justification of certain price increases
and various others have since-followed. The United States Congress has also introduced bills targeting prescription drug price transparency, and two such
bills—the Patient Right to Know Drug Prices Act (for private plans) and the Know the Lowest Price Act (for Medicare Parts C and D)—were signed into law
on October 10, 2018. These laws and any other such implementation of legislation requiring publication of drug costs could materially and adversely impact
our business, financial condition and results of operations by promoting a reduction in drug prices.

The scope and enforcement of these laws is uncertain and subject to change in the current environment of healthcare reform, especially in light of the
lack of applicable precedent and regulations. We are not able to predict the impact on our business of any changes in these laws. Federal or state regulatory
authorities may challenge our future activities under these laws. Any such challenge could have a material adverse effect on our reputation, business, results
of  operations  and  financial  condition.  Any  state  or  federal  regulatory  review  of  the  Company,  regardless  of  the  outcome,  would  be  costly  and  time-
consuming.

Our business, and our current and future activities, product candidates, or any future approved products, if any, may also be subject to equivalent
healthcare-related laws and regulations of any or all of the other countries, provinces, or other applicable jurisdictions in which we currently operate or may
operate in the future. There can be no assurance that the potential compliance obligations of any such foreign laws, and any corresponding consequences of
noncompliance, will be similar to those of United States fraud and abuse laws.

Healthcare legislative reform measures or other changes may have a material adverse effect on our business and results of operations.

In the United States, there have been a number of legislative and regulatory initiatives focused on containing the cost of healthcare. The Affordable
Care Act, for example, substantially changed the way healthcare is financed by both governmental and private insurers. The Affordable Care Act contains a
number of provisions that could impact our business and operations, primarily, once we obtain FDA approval to commercialize one of our product candidates
in the United States, if ever, and may also affect our operations in ways we cannot currently predict. ACA provisions that may affect our business include
those  governing  enrollment  in  federal  healthcare  programs,  reimbursement  changes,  rules  regarding  prescription  drug  benefits  under  health  insurance
exchanges,  expansion  of  the  340B  program,  expansion  of  state  Medicaid  programs  and  fraud  and  abuse  enforcement.  Such  changes  may  impact  existing
government  healthcare  programs,  industry  competition,  formulary  composition,  and  may  result  in  the  development  of  new  programs,  including  Medicare
payment for performance initiatives, health technology assessments and improvements to the physician quality reporting system and feedback program.

38

 
 
 
 
 
 
 
 
Since  taking  office,  President  Trump  has  continued  to  support  the  repeal  of  all  or  portions  of  the  Affordable  Care  Act.  However,  the  current
administration’s relevant repeal and/or reform efforts have been met with substantial opposition from various federal and state legislators and agencies and
other industry stakeholders, which has contributed to the current state of uncertainty as to the validity and application of healthcare reform measures initiated
thus far, the fate of the Affordable Care Act, and the current and future implications for applicable participants within the United States healthcare industry,
including providers, patients, manufacturers, developers, and other relevant individuals and institutions. The adoption or implementation of new or amended
legislation at the federal or state level could affect our ability to obtain regulatory approval for any of our vaccine candidates and the commercial viability of
our future approved products, if any. We cannot predict the ultimate nature, timing, or effect of any changes to the Affordable Care Act or other federal and
state reform efforts, and there is no assurance that such efforts will not adversely affect our future business and financial results.

In January 2017, Congress passed a budget resolution that authorizes congressional committees to draft legislation to repeal all or portions of the
Affordable Care Act and permits such legislation to pass with a majority vote in the Senate. President Trump also issued an executive order in which he stated
that it is his administration’s policy to seek the prompt repeal of the Affordable Care Act and directed executive departments and federal agencies to waive,
defer, grant exemptions from, or delay the implementation of the provisions of the Affordable Care Act to the maximum extent permitted by law.

Additionally, the Tax Cuts and Jobs Act of 2017 eliminated the Affordable Care Act provision requiring individuals to purchase and maintain health
coverage, or the “individual mandate,” by reducing the associated penalty to zero, beginning in 2019. In December 2018, a district court in Texas held that the
individual  mandate  is  unconstitutional  and  that  the  rest  of  the  Affordable  Care Act  is,  therefore,  invalid.  On  appeal,  the  Fifth  Circuit  Court  of  Appeals
affirmed the holding on the individual mandate but remanded the case back to the lower court to reassess whether and how such holding affects the validity of
the rest of the Affordable Care Act. Substantial uncertainty remains as to the future of the Affordable Care Act after the United States Supreme Court declined
to expedite its review of the Fifth Circuit’s holding on January 21, 2020. It is, thus, unlikely that these issues will be resolved before the next presidential
election in November 2020. There is no way to predict whether, and to what extent, if any, the Affordable Care Act will remain in-effect in the future, and it is
unclear  how  these  decisions,  subsequent  appeals,  or  other  efforts  to  repeal  and  replace  the  Affordable  Care  Act  will  impact  the  United  States  healthcare
industry or our business.

Our  internal  computer  systems,  or  those  of  our  third-party  vendors,  collaborators,  or  other  contractors  may  be  subject  to  various  federal  and
state confidentiality and privacy laws in the United States and abroad and could sustain system failures, security breaches, or other disruptions, any of
which could have a material adverse effect on our business.

Numerous international, national, federal, provincial and state laws, including state privacy laws (such as the California Consumer Privacy Act, or
“CCPA”),  state  security  breach  notification  and  information  security  laws,  and  federal  and  state  consumer  protection  laws  govern  the  collection,  use,  and
disclosure of personal information. In addition, most healthcare providers who may, in future, prescribe and dispense our products in the United States and
research  institutions  in  the  United  States  with  whom  we  collaborate  for  our  sponsored  clinical  trials  are  “covered  entities”  subject  to  privacy  and  security
requirements  under  HIPAA.  Among  other  things,  HITECH  makes  HIPAA’s  privacy  and  security  standards  directly  applicable  to  business  associates,
independent contractors, or agents of covered entities that receive or obtain protected health information in connection with providing a service on behalf of a
covered entity. HITECH also created four new tiers of civil monetary penalties, amended HIPAA to make civil and criminal penalties directly applicable to
business  associates,  and  gave  state  attorneys  general  new  authority  to  file  civil  actions  for  damages  or  injunctions  in  federal  courts  to  enforce  the  federal
HIPAA laws and seek attorneys’ fees and costs associated with pursuing federal civil actions. We could be subject to a wide range of penalties and sanctions
under  HIPAA,  including  criminal  penalties  if  we,  our  affiliates,  or  our  agents  knowingly  obtain  or  disclose  individually  identifiable  health  information
maintained by a covered entity in a manner that is not authorized or permitted by HIPAA. Failure to comply with applicable HIPAA requirements or other
current and future privacy laws and regulations could result in governmental enforcement actions (including the imposition of significant penalties), criminal
and civil liability, and/or adverse publicity that negatively affects our business.

39

 
 
 
 
 
 
 
Moreover,  we  rely  on  our  internal  and  third-party  provided  information  technology  systems  and  applications  to  support  our  operations  and  to
maintain  and  process  company  information  including  personal  information,  confidential  business  information  and  proprietary  information.  If  these
information technology systems are subject to cybersecurity attacks, or are otherwise compromised, due to cyberattacks, human error or malfeasance, system
errors  or  otherwise,  it  may  adversely  impact  our  business,  disrupt  our  operations,  or  lead  to  the  loss,  theft,  destruction,  corruption,  or  compromise  of  our
information or that of our collaborators, study subjects, or other third-party contractors, as applicable. Such information technology or security events could
also lead to legal liability, regulatory investigations or enforcement actions, loss of business, negative media coverage, and reputational damage. While we
seek to protect our information technology systems from these types of incidents, the healthcare sector continues to see a high frequency of cyberattacks and
increasingly sophisticated threat actors, and our systems and the information maintained within those systems remain potentially vulnerable to data security
incidents. Moreover, losses from such events may not be completely covered by insurance coverage (or may not be covered at all by any of our insurance
policies depending on the circumstances).

Any  of  the  above-described  cyber  or  other  security-related  incidents  may  trigger  notification  obligations  to  affected  individuals  and  government
agencies,  legal  claims  or  proceedings,  and  liability  under  foreign,  federal,  provincial  and  state  laws  that  protect  the  privacy  and  security  of  personal
information. Our proprietary and confidential information may also be accessed. Any one of these events could cause our business to be materially harmed
and our results of operations may be adversely impacted. Finally, as cyber threats continue to evolve, and privacy and cybersecurity laws and regulations
continue  to  develop,  we  may  need  to  invest  additional  resources  to  implement  new  compliance  measures,  strengthen  our  information  security  posture,  or
respond to cyber threats and incidents.

We could be adversely affected by violations of the United States Foreign Corrupt Practices Act and similar anti-bribery laws.

We  are  subject  to  the  United  States  Foreign  Corrupt  Practices  Act  and  similar  anti-corruption  laws  in  other  jurisdictions.  These  laws  generally
prohibit  companies  and  their  intermediaries  from  engaging  in  bribery  or  making  other  prohibited  payments  to  government  officials  for  the  purpose  of
obtaining or retaining business, and some have record keeping requirements. The failure to comply with these laws could result in substantial criminal and/or
monetary  penalties.  We  operate  in  jurisdictions  that  have  experienced  corruption,  bribery,  pay-offs  and  other  similar  practices  from  time-to-time  and,  in
certain circumstances, such practices may be local custom. Our Code of Business Conduct and Ethics mandates compliance with these anti-corruption laws.
However, we cannot be certain that these policies and procedures will protect us against liability. There can be no assurance that our employees, other agents,
or third-party manufacturers or other organizations will not engage in such conduct for which we might be held responsible. If our employees, other agents, or
third-party  manufacturers  or  other  organizations  are  found  to  have  engaged  in  such  practices,  we  could  suffer  severe  criminal  or  civil  penalties  and  other
consequences that could have a material adverse effect on our business, financial condition, results of operations, cash flows, and/ or share price.

We may expand our business through the acquisition of rights to new pipeline candidates that could disrupt our business and harm our financial

condition.

We may expand our product offerings, and we may seek acquisitions of pipeline candidates or technologies to do so. We may also seek to expand our
business  through  the  acquisition  of  businesses  or  companies  having  rights  to  new  pipeline  candidates.  Acquisitions  involve  numerous  risks,  including
substantial cash expenditures; potentially dilutive issuances of equity securities; incurrence of debt and contingent liabilities, some of which may be difficult
or  impossible  to  identify  at  the  time  of  the  acquisition;  difficulties  in  assimilating  the  acquired  technologies  or  the  operations  of  the  acquired  companies;
diversion of management’s attention away from other business concerns; risks of entering markets in which we have limited or no direct experience; and the
potential loss of key employees or key employees of the acquired companies.

40

 
 
 
 
 
 
 
 
There can be no assurance that any acquisition by us will result in short-term or long-term benefits to us. We may incorrectly judge the value or
worth of an acquired product, company or business. In addition, future success of the combined company will depend in part on our ability to manage the
rapid growth associated with some of these acquisitions. There can be no assurance that we will be able to make the combination of our business with that of
any acquired products, businesses or companies work or be successful. Furthermore, the development or expansion of our business or any acquired products,
businesses or companies may require a substantial capital investment by us. We may not have these necessary funds, or such funds might not be available on
acceptable terms or at all. We may also seek to raise funds by selling capital stock or instruments convertible into or exercisable for capital stock, which could
dilute each shareholder’s ownership interest.

Business interruptions could limit our ability to operate our business.

Our operations, as well as those of any collaborators on which we depend, are vulnerable to damage or interruption from computer viruses, human
error, natural disasters, extreme weather, electrical and telecommunication failures, international acts of terror, public health crises, such as pandemics and
epidemics,  and  similar  events.  Our  formal  disaster  recovery  plan  and  back-up  operations  and  business  interruption  insurance  may  not  be  adequate  to
compensate us for losses we may suffer. A significant business interruption could result in losses or damages incurred by us and require us to cease or curtail
our operations.

In December 2019, a novel strain of coronavirus was reported to have surfaced in Wuhan, China and has reached multiple other countries, resulting
in  government-imposed  quarantines,  travel  restrictions  and  other  public  health  safety  measures  in  China  and  such  other  countries.  We  and  Brii  Bio  are
conducting a Phase Ib/IIa clinical study of VBI-2601 (BRII-179) at multiple study sites including South Korea, Thailand, Hong Kong SAR and China. The
extent  to  which  the  coronavirus  may  impact  our  results  will  depend  on  future  developments,  which  are  highly  uncertain  and  cannot  be  predicted,  but
enrollment of patients in our study may be delayed due to the outbreak of the coronavirus, as hospitals in South Korea, Thailand, Hong Kong SAR and China
shift  resources  to  patients  affected  by  the  disease.  As  a  result,  our  expected  development  timeline  for  VBI-2601  (BRII-179)  may  be  negatively  impacted.
Moreover,  the  coronavirus  outbreak  has  begun  to  have  indeterminable  adverse  effects  on  general  commercial  activity  and  the  world  economy,  and  our
business and results of operations could be adversely affected to the extent that this coronavirus or any other epidemic harms the global economy generally.

Our business and operations would suffer in the event of computer system failures, cyber-attacks or deficiencies in our cyber-security.

In  the  ordinary  course  of  our  business,  we  collect  and  store  sensitive  data,  including  intellectual  property,  research  data,  our  proprietary  business
information and that of our suppliers, technical information about our products, clinical trial plans and employee records. Similarly, our third-party providers
possess  certain  of  our  sensitive  data  and  confidential  information.  The  secure  maintenance  of  this  information  is  critical  to  our  operations  and  business
strategy.  Despite  the  implementation  of  security  measures,  our  internal  computer  systems,  and  those  of  third  parties  on  which  we  rely,  are  vulnerable  to
damage from computer viruses, malware, ransomware, cyber fraud, natural disasters, terrorism, war, telecommunication and electrical failures, cyber-attacks
or cyber-intrusions over the Internet, attachments to emails, persons inside our organization, or persons with access to systems inside our organization. The
risk of a security breach or disruption, particularly through cyber-attacks or cyber-intrusion, including by computer hackers, foreign governments, and cyber
terrorists, has generally increased as the number, intensity and sophistication of attempted attacks and intrusions from around the world have increased. Any
such  breach  could  compromise  our  networks  and  the  information  stored  there  could  be  accessed,  publicly  disclosed,  encrypted,  lost  or  stolen.  Any  such
access,  inappropriate  disclosure  of  confidential  or  proprietary  information  or  other  loss  of  information,  including  our  data  being  breached  at  third-party
providers, could result in legal claims or proceedings, liability or financial loss under laws that protect the privacy of personal information, disruption of our
operations or our product development programs and damage to our reputation, which could adversely affect our business. 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.

Under  current  United  States,  Canadian  and  Israeli  law,  we  may  not  be  able  to  enforce  covenants  not  to  compete  or  to  prevent  the  breach  of
confidentiality agreements, and therefore, may be unable to prevent our competitors from benefiting from the expertise of some of our former employees.

We generally enter into non-competition agreements with our employees and certain key consultants. These agreements prohibit our employees and
certain key consultants, if they cease working for us, from competing directly with us or working for our competitors or clients for a limited period of time.
However, under current United States, Canadian and Israeli law, we may be unable to enforce these agreements, in whole or in part, and therefore, we cannot
be sure that these employees and key consultants will not compete with us. For example, in the past, Israeli courts have required employers seeking to enforce
non-compete undertakings of a former employee to demonstrate that the competitive activities of the former employee will harm one of a limited number of
material interests of the employer which have been recognized by the courts, such as the secrecy of a company’s confidential commercial information or the
protection  of  its  intellectual  property.  If  we  are  unable  to  demonstrate  that  harm  would  be  caused  to  us  or  otherwise  enforce  these  non-competition
agreements,  in  whole  or  in  part,  we  may  be  unable  to  prevent  our  competitors  from  benefitting  from  the  expertise  our  former  employees  or  consultants
developed while working for us and our ability to remain competitive may be diminished.

41

 
 
 
 
 
 
 
 
 
 
We  rely  on  confidential  information  that  we  seek  to  protect  through  confidentiality  agreements  with  our  employees  and  other  parties.  If  these
agreements are breached, competitors may obtain and use our confidential information to gain a competitive advantage over us or could substantially delay
product  development  or  harm  our  commercialization  activities.  We  may  not  have  any  remedies  against  our  competitors  and  any  remedies  that  may  be
available to us may not be adequate to protect our business or compensate us for the damaging disclosure. In addition, we may have to expend resources to
protect our interests from possible infringement by others, which may divert our available funds away from our business activities.

We  have  significant  operations  located  in  Israel  and,  therefore,  our  results  may  be  adversely  affected  by  political,  economic  and  military

instability in Israel.

Our subsidiary’s operations are located in Rehovot, Israel. Accordingly, political, economic and military conditions in Israel may directly affect our
business. Since the establishment of the State of Israel in 1948, a number of armed conflicts have taken place between Israel and its neighboring countries.
Any  hostilities  involving  Israel  or  the  interruption  or  curtailment  of  trade  between  Israel  and  its  trading  partners  could  adversely  affect  our  business  and
results of operations.

Any armed conflicts, terrorist activities or political instability in the region could adversely affect business conditions and could harm our results of
operations  and  could  make  it  more  difficult  for  us  to  raise  capital.  Parties  with  whom  we  do  business  have  sometimes  declined  to  travel  to  Israel  during
periods of heightened unrest or tension, forcing us to make alternative arrangements when necessary in order to meet our business partners face to face. In
addition, the political and security situation in Israel may result in parties with whom we have agreements involving performance in Israel claiming that they
are not obligated to perform their commitments under those agreements pursuant to force majeure provisions in such agreements.

Since the Gaza Strip’s 2007 coup, by which the terrorist organization Hamas seized control, there have been a number of armed conflicts between
Hamas and Israel – in December-January 2008-9, November 2012, July-August 2014 and as recently as May 2019 – in all of which conflicts, rockets were
fired from Gaza into Israeli civilian population centers. During the summer of 2006, Israel was engaged in an armed conflict with Hezbollah, a Lebanese
Islamist  Shiite  militia  group  and  political  party  backed  by  Iran  and  controlling  large  swathes  of  Lebanon.  These  conflicts  involved  missile  strikes  against
civilian targets in various parts of Israel, including areas in which our Rehovot facilities, employees and some of our consultants are located, and negatively
affected  business  conditions  in  Israel.  Civil  unrest  and  political  turbulence  has  occurred  in  other  countries  in  the  region,  including  Syria  which  shares  a
common  border  with  Israel,  and  is  affecting  the  political  stability  of  those  countries.  Since  April  2011,  a  civil  war  that  has  been  ongoing  in  Syria  has
escalated, and evidence indicates that chemical weapons have been used in the region. This instability and any intervention may lead to additional conflicts in
the region. In addition, Iran has threatened to attack Israel and is widely believed to be developing nuclear weapons. Iran also has a strong influence among
extremist groups in the region, such as Hamas in Gaza, Hezbollah in Lebanon, and both the Allawite regime and various rebel militia groups in Syria. These
situations may potentially escalate in the future to more violent events which may affect Israel and us. Any armed conflicts, terrorist activities or political
instability in the region could adversely affect business conditions and could harm our results of operations and could make it more difficult for us to raise
capital.

Commercial insurance does not cover losses that may occur as a result of an event associated with the security situation in the Middle East. Although
the Israeli government is currently committed to covering the reinstatement value of direct damages that are caused by terrorist attacks or acts of war, we
cannot assure that this government coverage will be maintained, or if maintained, will be sufficient to compensate us fully for damages incurred. Any losses
or  damages  incurred  by  us  could  have  a  material  adverse  effect  on  our  business.  Any  armed  conflicts  or  political  instability  in  the  region  would  likely
negatively affect business conditions generally and could harm our results of operations.

42

 
 
 
 
 
 
 
 
Political relations could limit our ability to sell or buy internationally.

We could be adversely affected by the interruption or reduction of trade between Israel and its trading partners. To date the State of Israel and Israeli
companies have been repeatedly subjected to economic boycotts. Several countries, companies and organizations continue to participate in a boycott of Israeli
firms  and  others  doing  business  with  Israel  or  with  Israeli  companies.  Also,  over  the  past  several  years  there  have  been  calls  in  Europe  and  elsewhere  to
reduce trade with Israel. These restrictive laws and policies may have an adverse impact on our operating results, financial condition or the expansion of our
business.

The operations of our subsidiary in Israel may be disrupted as a result of the obligation of Israeli citizens to perform military service.

Many Israeli citizens are obligated to perform several days, and in some cases more, of annual military reserve duty until they reach the age of 40 (or
older, for reservists who are officers or who have certain special training) and, in the event of a military conflict, may be called to active duty. In response to
increases in terrorist activity and recent armed conflicts, there have been periods of significant call-ups of military reservists. It is possible that there will be
military reserve duty call-ups in the future. The operations of our subsidiary in Israel could be disrupted by such call-ups, which may include the call-up of
our  employees  or  the  employees  of  our  Israeli  business  partners.  Such  disruption  could  materially  adversely  affect  our  business,  financial  condition  and
results of operations.

Exchange rate fluctuations between the United States dollar, Canadian dollar and the New Israeli Shekel currencies may negatively affect our

earnings cash flows.

Our functional currency is the United States dollar. We incur expenses in New Israeli Shekel, which we refer to as NIS, Canadian Dollars and United
States dollars. As a result, we are exposed to the risks that the United States dollar may devalue relative to the Canadian Dollar or NIS, or, if the United States
dollar appreciates relative to the Canadian Dollar or NIS, that the inflation rate in the United States may exceed such rate of devaluation of the United States
dollar, or that the timing of such devaluation may lag behind inflation in the United States. The average exchange rate for the year ended December 31, 2019,
was US$1.00 = NIS 3.564 and US$1.00 = C$1.3267. We cannot predict any future trends in the rate of inflation in the United States or the rate of devaluation,
if any, of the United States dollar against the Canadian Dollar or NIS.

Risks Related to Our Intellectual Property

Our success depends on our ability to maintain the proprietary nature of our technology. We may become subject to third parties’ claims alleging
infringement of patents and proprietary rights or seeking to invalidate our patents or proprietary rights, which would be costly, time-consuming and, if
successfully asserted against us, delay or prevent the development of our current or future pipeline candidates or commercialization of our products.

Our success in large part depends on our ability to maintain the proprietary nature of our technology. To do so, we must, at significant cost, prosecute
and maintain existing patents, obtain new patents and pursue trade secret and other intellectual property protection. We also must operate without infringing
the  proprietary  rights  of  third  parties  or  allowing  third  parties  to  infringe  our  rights.  We  currently  have  rights  to  over  142  fully  owned,  co-owned  or
exclusively licensed patents and patent applications. However, patent issues relating to pharmaceuticals and biologics involve complex legal, scientific and
factual questions.

To  date,  no  consistent  policy  has  emerged  regarding  the  breadth  of  biotechnology  patent  claims  that  are  granted  by  the  United  States  Patent  and
Trademark Office or enforced by the federal courts. Therefore, we do not know whether our patent applications will result in the issuance of patents, or that
any patents issued to us will provide us with any competitive advantage. We also cannot be sure that we will develop additional proprietary products that are
patentable. Furthermore, there is a risk that others will independently develop similar technology or products or circumvent the patents issued to us.

43

 
 
 
 
 
 
 
 
 
 
 
 
Even  if  we  are  issued  patents  for  our  technologies,  there  is  always  a  risk  that  third  parties  will  initiate  post  grant  review  or  inter  parties  review
proceedings to challenge the validity of one or more of our patents. These proceedings can result in the loss of patent claims. Even if we are successful in
defending  our  patents  during  post  grant  review  or  inter  parties  review  proceedings,  these  procedures  are  time  consuming  and  expensive  and  may  have  a
negative impact on our results.

There is also a risk that third parties may challenge our existing patents in court or claim that we are infringing their patents or proprietary rights. We
cannot assure you that the manufacture, use, sale, offer for sale, or importation of any of our products or current or future pipeline candidates will not infringe
existing or future patents. Because we have not conducted a formal freedom to operate analysis for patents related to our products or pipeline candidates, we
may not be aware of patents that have already been issued that a third-party might assert are infringed by one of our products or current or future pipeline
candidates. Because patent applications can take many years to issue and may be confidential for eighteen months or more after filing, there also may be
applications now pending of which we are unaware and which may later result in issued patents that we may infringe by commercializing any of our products
or current or future pipeline candidates. We could incur substantial costs in defending patent infringement suits or in filing suits against others to have their
patents  declared  invalid  or  to  claim  infringement  of  our  patents.  It  is  also  possible  that  we  may  be  required  to  obtain  licenses  from  third  parties  to  avoid
infringing third-party patents or other proprietary rights. We cannot be sure that such third-party licenses would be available to us on acceptable terms, if at
all. If we are unable to obtain required third-party licenses, we may be delayed in or prohibited from developing, manufacturing or selling products requiring
such licenses.

Although our patent filings include claims covering various features of our pipeline candidates, including composition, methods of manufacture and
use,  our  patents  do  not  provide  us  with  complete  protection  against  the  development  of  competing  products.  Furthermore,  follow-on  versions  of  patented
biologic products (i.e., biosimilars) may have structural differences that cause them to fall outside the scope of patent claims. Some of our know-how and
technology  is  not  patentable.  To  protect  our  proprietary  rights  in  unpatentable  intellectual  property  and  trade  secrets,  we  require  employees,  consultants,
advisors and collaborators to enter into confidentiality agreements. These agreements may not provide meaningful protection for our trade secrets, know-how
or other proprietary information.

Sci-B-Vac  is  not  currently  protected  by  any  pending  patent  application  nor  any  unexpired  patent.  Accordingly,  Sci-B-Vac  may  be  subject  to

competition from the sale of generic products that could adversely affect our business and operations.

Sci-B-Vac  has  no  patent  protection,  and  therefore,  we  will  seek  to  rely  on  non-patent  data  exclusivity  in  the  United  States  Biologics  Price
Competition  and  Innovation  Act  (the  “BPCI  Act”)  and  similar  legislation  in  other  countries,  which  is  described  further  under  “—Risks  Related  to  our
Intellectual Property —We may not be able to obtain marketing exclusivity in the United States under the BPCI Act or equivalent regulatory data exclusivity
protection in other jurisdictions for our products.”

Sci-B-Vac is the only product we currently market. Failure to obtain and retain marketing exclusivity or expiration of the market exclusivity could

seriously adversely affect the revenue potential for Sci-B-Vac in the jurisdictions where it is approved for sale.

Our ability to protect and enforce our patents does not guarantee that we will secure the right to commercialize the patents.

A patent is a limited monopoly right conferred upon an inventor, and any successors in title, in return for the making and disclosing of a useful, new,
and non-obvious invention. This monopoly is of limited duration but, while in force, allows the patent holder to prevent others from making and/or using his
invention. While a patent gives the holder this right to exclude others, it is not a license to commercialize the invention, where other permissions may be
required for permissible commercialization to occur. For example, a drug cannot be marketed in the United States without the appropriate authorization from
the  FDA,  regardless  of  the  existence  of  a  patent  covering  the  product.  Further,  the  invention,  even  if  patented  itself,  may  be  prohibited  from
commercialization if it infringes the valid patent rights of another party.

44

 
 
 
 
 
 
 
 
 
 
Obtaining  and  maintaining  our  patent  protection  depends  on  compliance  with  various  procedural,  documentary,  fee  payment  and  other
requirements  imposed  by  governmental  patent  offices,  and  our  patent  protection  could  be  reduced  or  eliminated  for  non-compliance  with  these
requirements.

The United States Patent and Trademark Office and various foreign governmental patent offices require compliance with a number of procedural,
documentary, fee payment and other provisions during the patent process. There are situations in which noncompliance can result in abandonment or lapse of
a patent or patent application, resulting in partial or complete loss of patent rights in the relevant jurisdiction. In such an event, competitors might be able to
enter the market earlier than would otherwise have been the case, which could result in a material adverse effect on our business or results of operations.

We are dependent on technologies we have licensed, and we may need to license in the future, and if we fail to obtain licenses we need, or fail to
comply with our payment obligations in the agreements under which we in-license intellectual property and other rights from third parties, we could lose
our ability to develop our pipeline candidates.

We  currently  are  dependent  on  licenses  from  third  parties  for  certain  of  our  key  technologies,  including  the  license  under  the  Ferring  License
Agreement and the license from UPMC. Under the Ferring License Agreement, we are committed to pay Ferring royalties equal to 7% of net sales (as defined
therein) of HbsAg “Product” (as defined therein). Under the SciGen Assignment Agreement, we are required to pay royalties to SciGen Ltd. equal to 5% of
net  sales  (as  defined  in  the  Ferring  License  Agreement)  of  Product.  Under  the  Ferring  License  Agreement  and  the  SciGen  Assignment  Agreement,  we
originally were to pay royalties on a country-by-country basis until the date 10 years after the date of commencement of the first royalty year in respect of
such country. In April 2019, we exercised our option to extend the Ferring License Agreement in respect of all the countries that still make up the territory for
an additional 7 years by making a one-time payment to Ferring of $100. Royalties under the Ferring License Agreement and SciGen Assignment Agreement
will continue to be payable for the duration of the extended license periods. Under our license agreement with UPMC and other licensors relating to eVLP
technology, we have an exclusive license to a family of patents and patent applications that is expected to expire in the United States in 2022 and 2021 in
other countries. Under this agreement, we are required to pay UPMC between 0.75% to 1.75% of net sales and certain lump-sum milestone payments. UPMC
is also a co-owner of the patent family covering our VBI-1501 CMV vaccine and we are currently negotiating extension of our existing license to cover this
patent family.

No assurance can be given that our existing license will be extended on reasonable terms or at all. In addition, we expect we will need to license
intellectual property from other third parties in the future and that these licenses will be material to our business. No assurance can be given that we will
generate  sufficient  revenue  or  raise  additional  financing  to  meet  our  payment  obligations  in  the  license  agreements  with  Ferring,  UPMC  or  other  license
agreements we enter into with third parties in the future. Any failure to make the payments required by the license agreements may permit the licensor to
terminate the license. If we were to lose or otherwise be unable to maintain these licenses for any reason, it would halt our ability to develop our pipeline
candidates.  Furthermore,  such  loss  of  these  licenses  may  enable  development  of  new  products  that  may  compete  with  our  pipeline  candidates,  and  our
competitors may gain proprietary position. Any of the foregoing could result in a material adverse effect on our business or results of operations.

In  addition,  we  do  not  own  the  patents  or  patent  applications  that  we  license,  and  as  such,  we  may  need  to  rely  upon  our  licensors  to  properly
prosecute and maintain those patent applications and prevent infringement of those patents. If our licensors are unable to adequately protect their proprietary
intellectual  property  we  license  from  legal  challenges,  or  the  Company  is  unable  to  enforce  such  licensed  intellectual  property  against  infringement  or
alternative technologies, we will not be able to compete effectively in the drug discovery and development business.

45

 
 
 
 
 
 
 
 
If patent laws or the interpretation of patent laws change, our competitors may be able to develop and commercialize our discoveries.

Important legal issues remain to be resolved as to the extent and scope of available patent protection for biopharmaceutical products and processes in
the United States and other important markets outside the United States, such as Europe, China and Japan. As such, litigation or administrative proceedings
may be necessary to determine the validity, scope and ownership of certain of our and others’ proprietary rights. Any such litigation or proceeding may result
in a significant commitment of resources in the future and could force us to do one or more of the following: cease selling or using any of our products that
incorporate the challenged intellectual property, which would adversely affect our revenue; obtain a license or other rights from the holder of the intellectual
property  right  alleged  to  have  been  infringed  or  otherwise  violated,  which  license  may  not  be  available  on  reasonable  terms,  if  at  all;  and  redesign  our
products  to  avoid  infringing  or  violating  the  intellectual  property  rights  of  third  parties,  which  may  be  time-consuming  or  impossible  to  do.  In  addition,
changes  in  patent  laws  in  the  United  States  and  other  countries  may  result  in  allowing  others  to  use  our  discoveries  or  develop  and  commercialize  our
products. We cannot provide assurance that the patents we obtain or the unpatented technology we hold will afford us significant commercial protection.

We may not be able to enforce our intellectual property rights throughout the world. This risk is exacerbated for us because we expect that one or

more of our pipeline candidates will be manufactured and used in a number of foreign countries.

The laws of foreign countries may not protect intellectual property rights to the same extent as the laws of the United States. Many companies have
encountered  significant  problems  in  protecting  and  defending  intellectual  property  rights  in  certain  foreign  jurisdictions.  This  risk  is  exacerbated  for  us
because we currently have one product manufactured, and we expect that one or more of our pipeline candidates will be manufactured, and used in a number
of foreign countries.

The  legal  systems  of  some  countries,  particularly  developing  countries,  do  not  favor  the  enforcement  of  patents  and  other  intellectual  property
protection, especially those relating to life sciences. This could make it difficult for us to stop the infringement or other misappropriation of our intellectual
property rights. For example, several foreign countries have compulsory licensing laws under which a patent owner must grant licenses to third parties. In
addition, some countries limit the enforceability of patents against third parties, including government agencies or government contractors. In these countries,
patents and trade secrets may provide limited or no benefit.

Most jurisdictions in which we have applied for, intend to apply for or have been issued patents have patent protection laws similar to those of the
United States, but some of them do not. For example, in addition to the collaboration with Brii Bio, we may do business in China, Indonesia and India in the
future and the countries in these regions may not provide the same or similar protection as that provided in the United States. Additionally, due to uncertainty
in patent protection law, we have not filed applications in many countries where significant markets exist.

Proceedings to enforce patent rights in foreign jurisdictions could result in substantial costs and divert our efforts and attention from other aspects of
our business. Accordingly, efforts to protect our intellectual property rights in such countries may be inadequate. In addition, changes in the law and legal
decisions by courts in the United States and foreign countries may affect our ability to obtain adequate protection for our technology and the enforcement of
our intellectual property.

We may not be able to monetize intangible assets, including In Process Research and Development (“IPR&D”) and goodwill, which may result

in the need to record an impairment charge.

Our balance sheet contains approximately $60.8 million of intangible assets. For IPR&D assets, the risk of failure is significant, and there can be no
certainty that these assets ultimately will yield successful products. The nature of our business is high-risk and requires that we invest in a large number of
projects in an effort to achieve a successful portfolio of approved products. Our ability to realize value on these significant investments is often contingent
upon, among other things, regulatory approvals and market acceptance. These IPR&D and goodwill assets may become impaired and be written off at some
time in the future. An example of an event that is indicative of impairment is a projection or forecast that indicates losses or reduced profits associated with an
asset or the market capitalization of a company falling below the net equity value. For IPR&D projects, this could result from, among other things, a change
in outlook based on clinical trial data, a delay in the projected launch date or additional expenditures to commercialize the product. During the third quarter of
2019 to date, our market capitalization was below our net equity value for a substantial number of days, and we recorded an impairment charge for the year
ended December 31, 2019 of $6,292 in the consolidated statement of operations and comprehensive loss.

46

 
 
 
 
 
 
 
 
 
 
 
While  all  intangible  assets  can  face  events  and  circumstances  that  can  lead  to  impairment,  in  general,  intangible  assets  that  are  most  at  risk  of

impairment include IPR&D assets. IPR&D assets are high-risk, as research and development is an inherently risky activity.

We may not be able to obtain marketing exclusivity in the United States under the BPCI Act or equivalent regulatory data exclusivity protection

in other jurisdictions for our products.

The  BPCI  Act,  which  is  included  in  the  Affordable  Care  Act,  provides  the  manufacturer  of  innovator  biologic  to  seek  a  twelve-year  period  of
marketing exclusivity. Similar data exclusivity regimes exist in the European Union and in Canada, although the term of market exclusivity is shorter than in
the United States. We intend to seek the maximum period of market exclusivity for Sci-B-Vac and our other pipeline candidates in each jurisdiction, but there
is  no  guarantee  that  any  of  our  products  will  receive  any  marketing  exclusivity  under  the  BPCI  Act,  or  under  analogous  legislation  in  other  jurisdictions.
Furthermore, changes in applicable law could alter any period of market exclusivity or limit its availability. Our failure to obtain exclusivity for any product
that is ultimately approved by the FDA, the EMA or Health Canada may expose us to substantial competition, which could have significant adverse financial
consequences.

Risks Related to Our Indebtedness

Our  obligations  under  our  credit  facility  are  secured  by  substantially  all  of  our  assets,  so  if  we  default  on  those  obligations,  the  lender  could
foreclose on our assets. As a result of these security interests, such assets would only be available to satisfy claims of our general creditors or to holders of
our  equity  securities  if  we  were  to  become  insolvent  at  a  time  when  the  value  of  such  assets  exceeded  the  amount  of  our  indebtedness  and  other
obligations.

Perceptive  Credit  Holdings,  LP  (“Perceptive  Credit”),  pursuant  to  the  Amended  and  Restated  Credit  Agreement  and,  dated  December  6,  2016  as
amended (the “Amended Credit Facility”), has a security interest in all of our assets other than excluded and future projects. As a result, if we default under
our obligations to the lender, the lender could foreclose on its security interests and liquidate some or all of these assets, which would harm our business,
financial condition and results of operations. The principal amount of the term loan as of December 31, 2019, was $15.0 million ($15.3 million including the
exit fee).

In  the  event  of  a  default  in  connection  with  our  bankruptcy,  insolvency,  liquidation,  or  reorganization,  the  lender  would  have  a  prior  right  to
substantially all of our assets to the exclusion of our general creditors. In that event, our assets would first be used to repay in full all indebtedness and other
obligations secured by the lender, resulting in all or a portion of our assets being unavailable to satisfy the claims of any unsecured indebtedness. Only after
satisfying the claims of any unsecured creditors would any amount be available for our equity holders. These events of default include, among other things,
our failure to pay any amounts due under the Amended Credit Facility or any of the other loan documents, a breach of covenants under the Amended Credit
Facility,  our  insolvency,  a  material  adverse  effect  occurring,  the  occurrence  of  certain  defaults  under  certain  other  indebtedness  or  certain  final  judgments
against us.

The pledge of these assets and other restrictions may limit our flexibility in raising capital for other purposes. Because substantially all of our assets
are pledged under the term loan, our ability to incur additional secured indebtedness or to sell or dispose of assets to raise capital may be impaired, which
could have an adverse effect on our financial flexibility.

If  we  are  unable  to  comply  with  certain  financial  and  operating  restrictions  in  our  existing  credit  facility,  we  may  be  limited  in  our  business

activities and access to credit or may default under our credit facility.

Provisions in the Amended Credit Facility impose restrictions or require prior approval on our ability, and the ability of certain of our subsidiaries to,

among other things:

● incur additional debt;

● pay cash dividends and make distributions;

● make certain investments and acquisitions;

47

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
● guarantee the indebtedness of others or our subsidiaries;

● redeem or repurchase capital shares;

● create liens or encumbrances;

● enter into transactions with affiliates;

● engage in new lines of business;

● sell, lease or transfer certain parts of our business or property;

● incur obligations for capital expenditures;

● issue additional capital shares; and

● acquire new companies and merge or consolidate.

The Amended  Credit  Facility  also  contains  other  customary  covenants,  including  covenants  that  require  us  to  meet  specified  financial  ratios  and
financial tests and maintain a minimum cash balance of $2.5 million. We may not be able to comply with these covenants in the future. Our failure to comply
with  these  covenants  may  result  in  the  declaration  of  an  event  of  default,  which,  if  not  cured  or  waived,  may  result  in  the  acceleration  of  the  maturity  of
indebtedness outstanding under this agreement and would require us to pay all amounts outstanding. If the maturity of our indebtedness is accelerated, we
may  not  have  sufficient  funds  available  for  repayment  or  we  may  not  have  the  ability  to  borrow  or  obtain  sufficient  funds  to  replace  the  accelerated
indebtedness on terms acceptable to us or at all. Our failure to repay our indebtedness would result in our lender foreclosing on all or a portion of our assets
and force us to curtail or cease our operations.

Our outstanding term loan obligations may adversely affect our cash flow and our ability to operate our business.

Pursuant to the terms of Amended Credit Facility, the lender made a term loan to us in aggregate amount of $15.0 million. In 2019, we made average
monthly payments of interest in the amount of approximately $170. Commencing January 2020, our monthly payments include capital repayments of $200
until June 2020, when the entire amount is due. On July 17, 2018, the Amended Credit Facility was amended by the second amendment, pursuant to which
we were required to make monthly interest payments plus monthly principal payments in the amount of approximately $200 per month from January 2019
until the loan matures and to extend the expiration date of certain warrants to purchase 363,771 common shares issued to Perceptive Credit with an original
expiration date of July 25, 2019 to December 6, 2021. As amended by the second amendment, the term loan was set to mature on December 31, 2019. On
January 31, 2019, we further amended the Amended Credit Facility by the third amendment to (i) extend the period we are required to pay only the interest on
the loan from December 31, 2018, to January 31, 2020, (ii) extend the maturity of the term loan to June 30, 2020, and (iii) reduce the exercise price of certain
warrants to purchase common shares issued to Perceptive Credit to $2.75 from $4.13 for 363,771 warrants issued on July 25, 2014, and for 363,771 warrants
issued on December 6, 2016, and from $3.355 for 1,341,282 warrants issued on December 6, 2016. The principal amount of the term loan as of December 31,
2019, was $15.0 million ($15.3 million including the exit fee).

The terms of our term loan could have negative consequences to us, such as:

● we may be unable to obtain additional financing to fund working capital, operating losses, capital expenditures or acquisitions on terms acceptable to

us, or at all;

● the amount of our interest expense may increase because our term loan has a variable rate of interest at any time dependent on one-month London

Interbank Offered Rate greater than 1%; and

● we may be more vulnerable to economic downturns and adverse developments in our industry or the economy in general.

Our  ability  to  meet  our  expenses  and  debt  obligations  will  depend  on  our  future  performance,  which  will  be  affected  by  financial,  business,
economic, regulatory and other factors. We will be unable to control many of these factors, such as economic conditions. We cannot be certain that we will
continue to have sufficient capital to allow us to pay the principal and interest on our debt and meet any other obligations. If we do not have enough money to
service our debt, we may be required, but unable to refinance all or part of our existing debt, sell assets, borrow money or raise equity on terms acceptable to
us, if at all, and the lender could foreclose on its security interests and liquidate some or all of our assets.

Risks Related to Our Common Shares

The price of our common shares has been, and may continue to be, volatile. This may affect the ability of our investors to sell their shares, and

the value of an investment in our common shares may decline.

During the 12-month period ended December 31, 2019, our common shares traded as high as $2.20 per share and as low as $0.466 per share. The
market prices of our common shares may continue to be volatile and could fluctuate widely in response to various factors, many of which are beyond our
control, including the following:

● future announcements about us, our collaborators or competitors, including the results of testing, technological innovations, or new products

and services;

● clinical trial results;

● depletion of cash reserves;

● additions or departures of key personnel;

● operating results that fall below expectations;

● announcements by us relating to any strategic relationship;

● sales of equity securities or issuance of additional debt;

● industry developments;

● changes in state, provincial or federal regulations affecting us and our industry;

● economic, political and other external factors; and

● period-to-period fluctuations in our financial results.

Furthermore, the stock market in general and the market for biotechnology companies, in particular, have from time to time experienced extreme
price and volume fluctuations that are unrelated or disproportionate to the operating performance of the affected companies. Such broad market fluctuations
may adversely affect the market price of our common shares.

We may not meet the continued listing requirements of The NASDAQ Capital Market, which could result in a delisting of our common shares.

Our common shares are listed on the NASDAQ Capital Market. We have in the past, and may in the future, be unable to comply with certain of the
listing standards that we are required to meet to maintain the listing of our common shares on the NASDAQ Capital Market. For instance, on August 14,
2019, we received a letter from the Listing Qualifications Department of NASDAQ indicating that, based upon the closing bid price of our common shares
for the 30 consecutive business day period between July 2, 2019 through August 13, 2019, we did not meet the minimum bid price of $1.00 per share required
for  continued  listing  on  The  NASDAQ  Capital  Market  pursuant  to  NASDAQ  Listing  Rule  5550(a)(2).  On  January  9,  2020  we  received  notice  from  the
NASDAQ  indicating  that  the  Company  has  regained  compliance  with  the  minimum  bid  price  requirement  under  Nasdaq  Listing  Rule  5550(a)(2),  and  the
matter is now closed.

If  the  NASDAQ  Capital  Market  delists  our  common  shares  from  trading  on  its  exchange  for  failure  to  meet  the  listing  standards,  we  and  our

shareholders could face significant material adverse consequences including:

● a limited availability of market quotations for our securities;

● a determination that our common shares are a “penny stock” which will require brokers trading in our common shares to adhere to more stringent

rules, possibly resulting in a reduced level of trading activity in the secondary trading market for our common shares;

● a limited amount of analyst coverage; and

● a decreased ability to issue additional securities or obtain additional financing in the future.

Delisting could also have other negative results, including the potential loss of confidence by employees, the loss of institutional investor interest and fewer
business development opportunities.

We have no immediate plans to pay dividends.

We plan to reinvest all of our earnings, to the extent we have earnings, in order to market our products and to cover operating costs and to otherwise
become and remain competitive. We do not plan to pay any cash dividends with respect to our securities in the foreseeable future. We cannot assure you that
we would, at any time, generate sufficient surplus cash that would be available for distribution to the holders of our common shares as a dividend. In addition,
our Amended Credit Facility with Perceptive Credit prohibits us from declaring or paying cash dividends or making distributions on any class of our capital
stock. We currently intend to retain earnings, if any, for reinvestment in our business. Therefore, holders of our common shares should not expect to receive
cash dividends on our common shares.

Common shares eligible for future sale may cause the price of our common shares to decline.

From time to time, certain of our shareholders may be eligible to sell all or some of their restricted common shares by means of ordinary brokerage
transactions in the open market pursuant to Rule 144, promulgated under the Securities Act of 1933, as amended, subject to certain limitations. In general,
pursuant to Rule 144, non-affiliate shareholders may sell freely after six months, subject only to the current public information requirement (which disappears
after  one  year).  Of  the  178,257,199  common  shares  outstanding  as  of  December  31,  2019,  approximately  117,781,686  common  shares  are  held  by  “non-
affiliates,” all of which are currently freely tradable either because those were issued in a registered offering or pursuant to Rule 144.

Any  substantial  sale  of  our  common  shares  pursuant  to  Rule  144  or  pursuant  to  any  resale  prospectus  may  have  a  material  adverse  effect  on  the

market price of our common shares.

In  addition,  as  of  December  31,  2019,  we  had  outstanding  options,  awards,  and  warrants  for  the  purchase  of  9,248,529  common  shares.  Of  this
amount,  options,  awards  and  warrants  for  the  purchase  of  1,369,105  common  shares  are  held  by  non-affiliates,  who  may  sell  these  shares  in  the  public
markets from time to time, without limitations on the timing, amount or method of sale. If our share price rises, the holders may exercise their options and sell
a large number of shares. This could cause the market price of our common shares to decline.

We are required to comply with the domestic reporting regime under the Securities Exchange Act of 1934, as amended, and incur significant
legal, accounting and other expenses and resources, and our management are required to devote substantial time to compliance initiatives and corporate
governance practices.

We  are  required  to  comply  with  all  of  the  periodic  disclosure  and  current  reporting  requirements  of  the  Securities  Exchange  Act  of  1934,  as
amended, applicable to a publicly traded United States domestic issuer. The obligations of being a public reporting company require significant expenditures,
including costs resulting from public company reporting obligations under the Securities Exchange Act of 1934, as amended, and the rules and regulations
regarding corporate governance practices, including those under the Sarbanes-Oxley Act, the Dodd-Frank Wall Street Reform and Consumer Protection Act,
and  the  listing  requirements  of  the  Nasdaq  Capital  Market.  These  rules  require  the  establishment  and  maintenance  of  effective  disclosure  and  financial
controls and procedures, internal control over financial reporting and corporate governance practices, among many other complex rules that are often difficult
and time consuming to implement, monitor and maintain compliance with. Moreover, despite recent reforms made possible by the JOBS Act, the reporting
requirements,  rules,  and  regulations  will  make  some  activities  more  time-consuming  and  costly,  particularly  after  we  are  no  longer  an  “emerging  growth
company.”  In  addition,  these  rules  and  regulations  make  it  more  difficult  and  more  expensive  for  us  to  obtain  director  and  officer  liability  insurance.
Compliance with such requirements also places significant demands on our management, administrative, operational, internal audit and accounting resources.
As a result, we incur, and we expect to continue to incur, legal and financial compliance costs and some activities are highly time consuming and costly.

There are inherent limitations in all control systems, and misstatements due to error or fraud may occur and not be detected.

The ongoing internal control provisions of Section 404 of the Sarbanes-Oxley Act require us to identify material weaknesses in internal control over
financial reporting, which is a process to provide reasonable assurance regarding the reliability of financial reporting for external purposes in accordance with
accounting principles generally accepted in the United States. Our management, including our chief executive officer and principal financial officer, does not
expect that our internal controls and disclosure controls 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. In addition, the design of a control system must reflect
the fact that there are resource constraints and the benefit of controls must be 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,  in  our  company  have  been  detected.  These
inherent limitations include the realities that judgments in decision-making can be faulty and that breakdowns can occur because of simple errors or mistakes.
Further, controls can be circumvented by individual acts of some persons, by collusion of two or more persons, or by management override of the controls.
The design of any system of controls is also 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 our stated goals under all potential future conditions. Over time, a control may be inadequate because of changes in
conditions,  such  as  growth  of  the  company  or  increased  transaction  volume,  or  the  degree  of  compliance  with  the  policies  or  procedures  may  deteriorate.
Because of inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.

In addition, discovery and disclosure of a material weakness, by definition, could have a material adverse impact on our financial statements. Such
an occurrence could discourage certain customers or suppliers from doing business with us, cause downgrades in our future debt ratings leading to higher
borrowing costs and affect how our common shares trade. This could, in turn, negatively affect our ability to access public debt or equity markets for capital.

We are an “emerging growth company” and may elect to comply with reduced public company reporting requirements, which could make our

common shares less attractive to investors.

We  are  an  “emerging  growth  company,”  as  defined  in  the  Jumpstart  Our  Business  Startups  Act.  For  as  long  as  we  continue  to  be  an  “emerging
growth company”, we may take advantage of exemptions from various reporting requirements that are applicable to other public reporting companies that are
not emerging growth companies, including not being required to comply with the auditor attestation requirements of Section 404(b) of the Sarbanes-Oxley
Act  and  reduced  disclosure  obligations  regarding  executive  compensation  in  our  periodic  reports.  We  could  be  an  “emerging  growth  company”  up  until
December 31, 2021, although circumstances could cause us to lose that status earlier if our annual revenues exceed $1.07 billion, if we issue more than $1.0
billion in non-convertible debt in any three-year period or if the market value of our common shares held by non-affiliates exceeds $700.0 million as of any
June 30th, in which case we would no longer be an “emerging growth company” as of the following December 31st. We cannot predict if investors will find
our securities less attractive because we may rely on these exemptions. If some investors find our securities less attractive as a result, there may be a less
active trading market for our securities and the price of our securities may be more volatile.

United States civil liabilities may not be enforceable against us or certain of our officers.

We  are  governed  by  the  Business  Corporations  Act  (British  Columbia)  (“BCBCA”)  and  a  substantial  portion  of  our  assets,  including  our
manufacturing facility in Rehovot, Israel, and our research facility in Ottawa, Canada, are located outside the United States. As a result, it may be difficult for
investors  to  effect  service  of  process  within  the  United  States  upon  us  or  to  enforce  judgments  obtained  against  us  in  United  States  courts,  in  any  action,
including actions predicated upon the civil liability provisions of United States federal securities laws or any other laws of the United States. Additionally,
rights predicated solely upon civil liability provisions of United States federal securities laws or any other laws of the United States may not be enforceable in
original actions, or actions to enforce judgments obtained in United States courts, brought in Canadian or Israeli courts. In addition, two of our officers reside
outside of the United States, and all or a substantial portion of their assets may be located outside the United States, which may make effecting service of
process within the United States or enforcing judgments obtained against such persons in United States courts difficult.

51

 
 
 
 
 
 
 
 
 
We are governed by the corporate laws of British Columbia which in some cases have a different effect on shareholders than the corporate laws

of Delaware, United States.

We are governed by the BCBCA and other relevant laws, which may affect the rights of shareholders differently than those of a company governed
by  the  laws  of  a  United  States  jurisdiction,  and  may,  together  with  our  charter  documents,  including  the  advance  notice  provisions  in  our  articles  for  the
nomination of directors, have the effect of delaying, deferring or discouraging another party from acquiring control of our company by means of a tender
offer, a proxy contest or otherwise, or may affect the price an acquiring party would be willing to offer in such an instance. The material differences between
the BCBCA and Delaware General Corporation Law, or DGCL, that may have the greatest such effect include, but are not limited to, the following: (i) for
material corporate transactions (such as mergers and amalgamations, other extraordinary corporate transactions or amendments to our articles) the BCBCA
generally requires a two-thirds majority vote by shareholders, whereas DGCL generally only requires a majority vote; and (ii) under the BCBCA a holder of
5% or more of our common shares can requisition a special meeting of shareholders, whereas such right does not exist under the DGCL.

We may be subject to securities litigation, which is expensive and could divert management attention.

In the past, companies that have experienced volatility in the market price of their securities have been subject to securities class action litigation. We
may be the target of this type of litigation in the future. Litigation of this type could result in substantial costs and diversion of management’s attention and
resources, which could seriously hurt our business. Any adverse determination in litigation could also subject us to significant liabilities.

The  concentration  of  the  capital  stock  ownership  with  our  insiders  will  likely  limit  the  ability  of  other  shareholders  to  influence  corporate

matters.

As of December 31, 2019, approximately 33.9% of our outstanding common shares was controlled by our officers, directors, beneficial owners of
10% or more of our securities and their respective affiliates. As a result, these shareholders, if they acted together, may be able to determine or influence
matters  that  require  approval  by  our  shareholders,  including  the  election  of  directors  and  approval  of  significant  corporate  transactions.  Corporate  actions
might  be  taken  even  if  other  shareholders  oppose  them.  This  concentration  of  ownership  might  also  have  the  effect  of  delaying  or  preventing  a  corporate
transaction that other shareholders may view as beneficial.

If  securities  or  industry  analysts  do  not  publish  research  or  publish  inaccurate  or  unfavorable  research  about  our  business,  the  price  of  our

common shares and trading volume could decline.

The trading market for our common shares will depend in part on the research and reports that securities or industry analysts publish about us or our
business. Multiple securities and industry analysts currently cover us. If one or more of the analysts downgrade our common shares or publish inaccurate or
unfavorable research about our business, the price of our common shares would likely decline. If one or more of these analysts cease coverage of us or fail to
publish reports on us regularly, demand for our common shares could decrease, which could cause the price of our common shares and trading volume to
decline.

ITEM 2: PROPERTIES

We rent office and research facility space under several operating leases.

a) Our headquarters, which is currently comprised of approximately 3,475 square feet of office space, is held pursuant to a lease agreement that
was  entered  into  on  May  31,  2012  with  American  Twine  Limited  Partnership,  subsequent  assigned  to  American  Twine  Owner  LLC,  and
currently pursuant to the sixth amendment we have extended the lease to April 30, 2020 with a base rent for the premises of $19 per month. The
lease has been amended since it was entered into for the purpose of revising the length, providing for a new base rent and adding additional
office space. We are also responsible for the payment of additional rent, including our pro rata share of real estate taxes, operating expenses, as
defined in the lease, and betterment assessments, as defined in the lease.

b) Our manufacturing facility, which is currently comprised of approximately of 3,586 square meters of manufacturing suite, laboratory and office
space is held pursuant to a lease agreement that was entered into on June 16, 2006 with Eilot Hashkaot and has been amended five times since it
was entered into for the purpose of revising the length of the term, providing for a new base rent and adding additional office space. The amount
of the lease is approximately $34 per month and linked to the CPI. The commitments for existing and additional space are for a term of five
years ending January 31, 2022, with a five-year option to extend until January 31, 2027 with an increase of 10%.

On January 16, 2017, we entered into a sublease agreement for additional office space of 200 square meters with Green Power YE. The term of
the sub lease has been extended twice, and on January 15, 2019, we signed a three year and 9 day extension for the sub lease agreement, the
amount of the extended sub lease was for a fixed price including all rental utilities of $7 per month.

c) VBI Cda’s  research  facility,  which  is  comprised  of  laboratory  and  office  space,  is  held  pursuant  to  a  sub-sublease  that  was  entered  into  on
September 1, 2014 with Iogen Corporation and subsequently amended to include some additional space had an initial term ending on December
31, 2019 with the option to extend the term for two periods of three years each. On September 5, 2019, the sub-sublease was assigned by Iogen
Corporation to 310 Hunt Club GP Inc. (“the Assignee”) and the term of the sub-sub-lease was extended until December 31, 2022 with an option
to extend the lease for one additional three year period. The base and additional rent for the premises is approximately $21 USD per square foot
per year through December 31, 2022. VBI Cda is also responsible for its pro rata share of additional rent, payable monthly, which includes, but
is not limited to, operating and maintenance costs, real estate taxes, general maintenance and repair costs, insurance and professional fees. In
addition to the base rent and the additional rent, VBI Cda is responsible for the payment of a refundable harmonized sales tax as require by the
Excise Tax Act (Canada). Pursuant to the sub-sublease, the additional rent per month will not exceed $20.50 dollars CAD per square foot of
rentable premises. VBI Cda was required to provide a security deposit in the amount of $18.80 CAD which the Assignee will hold until the end
of the term and may, in the event of a failure by VBI Cda to pay rent as and when due, apply the security deposit to the unpaid rent obligation.

Pursuant to these leases, we made rent payments of $1,128 in 2019.

We  believe  that  our  office,  manufacturing  and  research  facilities  are  suitable  and  adequate  for  our  current  operations  but  will  consider  term

extensions or expansion of leased space, depending on market conditions and needs.

ITEM 3: LEGAL PROCEEDINGS

From  time  to  time,  the  Company  may  be  involved  in  certain  claims  and  litigation  arising  out  of  the  ordinary  course  and  conduct  of  business.
Management assesses such claims and, if it considers that it is probable that an asset had been impaired or a liability had been incurred and the amount of loss
can be reasonably estimated, provisions for loss are made based on management’s assessment of the most likely outcome.

On September 13, 2018, two actions were brought in the District Court of the central district in Israel naming our subsidiary SciVac as a defendant.
In one claim, two minors, through their parents, allege among other things, defects in certain batches of Sci-B-Vac discovered in July 2015; that Sci-B-Vac
was approved for use in children and infants in Israel without sufficient evidence establishing its safety; that SciVac failed to provide accurate information
about Sci-B-Vac to consumers and that each child suffered side effects from the vaccine. The claim was filed together with a motion seeking approval of a
class action on behalf of 428,000 children vaccinated with Sci-B-Vac in Israel from April, 2011 and seeking damages in a total amount of NIS 1,879,500,000
(not in thousands) ($543,837). The second claim is a civil action brought by two minors and their parents against SciVac and the IMoH alleging, among other
things,  that  SciVac  marketed  an  experimental,  defective,  hazardous  or  harmful  vaccine;  that  Sci-B-Vac  was  marketed  in  Israel  without  sufficient  evidence
establishing its safety; and that Sci-B-Vac was produced and marketed in Israel without approval of a western regulatory body. The claim seeks damages for
past and future losses and expenses as well as punitive damages.

SciVac believes these matters to be without merit and intends to defend these claims vigorously.

The District Court accepted SciVac’s motion to suspend reaching a decision on the approval of the class action pending the determination of liability

under the civil action. Preliminary hearings for the trial of the civil action began on January 15, 2020.

Overview

We are a commercial-stage, biopharmaceutical company developing a next generation of vaccines to address unmet needs in infectious disease and
immuno-oncology. We are advancing the prevention and treatment of hepatitis B, with the only trivalent hepatitis B vaccine, Sci-B-Vac®, which is approved
for use and commercially available in Israel, and recently completed a pivotal Phase III program in the United States, Europe, and Canada, and with VBI-
2601  (BRII-179),  an  immunotherapeutic  candidate  in  development  in  collaboration  with  Brii  Biosciences  Limited  (“Brii  Bio”)  for  a  functional  cure  for
chronic hepatitis B. Our enveloped virus-like particle (“eVLP”) platform technology allows for the development of eVLP vaccines that closely mimic the
target  virus  to  elicit  a  potent  immune  response.  Integrating  our  cytomegalovirus  (“CMV”)  expertise  with  the  eVLP  platform  technology,  our  lead  eVLP
program  candidates  include  a  glioblastoma  (“GBM”)  vaccine  immunotherapeutic  candidate,  VBI-1901,  and  a  prophylactic  CMV  vaccine  candidate,  VBI-
1501. We are headquartered in Cambridge, Massachusetts, with research operations in Ottawa, Canada, and manufacturing operations in Rehovot, Israel.

Sci-B-Vac: Trivalent Prophylactic Hepatitis B Vaccine

Current
Development Stage

Phase III Complete
Phase Ib/IIa

Phase I/IIa
Phase I Complete

Sci-B-Vac is a trivalent prophylactic hepatitis B vaccine, which is approved for use and commercially available in Israel, and recently completed its
pivotal Phase III program in the United States, Europe, and Canada. In contrast to other commercially-available hepatitis B vaccines, which contain only one
surface antigen (the S antigen) of hepatitis B, Sci-B-Vac contains all three of the hepatitis B surface antigens: the S antigen, the pre-S1 antigen, and the pre-S2
antigen. Moreover, Sci-B-Vac is distinguished from other commercially-approved hepatitis B vaccines because it is produced in mammalian cells (Chinese
hamster  ovary  “CHO”  cells)  rather  than  in  yeast.  Published  data  demonstrate  that  T  cell  responses  to  the  pre-S1  and  pre-S2  antigens  can  further  boost
responses to the S antigen, resulting in a more immunogenic response.

Sci-B-Vac has not yet been approved for use by the United States Food and Drug Administration (“FDA”), European Medicines Agency (“EMA”) or
Health  Canada.  The  recently-completed  global  Phase  III  clinical  program  was  designed  to  achieve  FDA,  EMA,  and  Health  Canada  market  approvals  for
commercial  sale  of  Sci-B-Vac  in  the  United  States,  Europe,  and  Canada  respectively.  Our  wholly-owned  subsidiary,  SciVac  Ltd.,  in  Rehovot,  Israel,
manufactures and sells Sci-B-Vac.

On  June  17,  2019,  we  announced  positive  top-line  results  from  the  randomized,  double-blind,  controlled  pivotal  Phase  III  study,  PROTECT,
designed to evaluate the efficacy and safety of a 10µg dose of Sci-B-Vac compared with a 20µg dose of the standard-of-care vaccine, Engerix-B®. The study,
which enrolled a total of 1,607 adults, of which 81% were age ≥ 45 years, met both of its co-primary endpoints: (1) non-inferiority of seroprotection rate
(“SPR”) of Sci-B-Vac (91.4%) vs. Engerix-B (76.5%) in all subjects age ≥ 18 years, 4 weeks after 3rd vaccination (SPR difference: 14.9%; 95% confidence
interval  (“CI”)  [11.2%,  18.5%]);  and  (2)  superiority  of  SPR  of  Sci-B-Vac  (89.4%)  vs.  Engerix-B  (73.1%)  in  subjects  age  ≥  45  years,  4  weeks  after  3rd
vaccination  (SPR  difference:  16.4%;  95%  CI  [12.2%,  20.7%]).  Moreover,  the  SPR  of  Sci-B-Vac  compared  to  Engerix-B  was  higher  in  all  key  subgroup
analyses of adults age ≥ 18 years, including by age, gender, body mass index (“BMI”), diabetic status, and smoking status, four weeks after 3rd vaccination.

55

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
On  January  9,  2020  we  reported  positive  top-line  results  from  CONSTANT,  the  second  pivotal  Phase  III  study,  designed  to  assess  lot-to-lot
manufacturing consistency of Sci-B-Vac, and compare the safety and immunogenicity of Sci-B-Vac to Engerix-B. The CONSTANT Phase III study, which
enrolled  2,838  adults,  age  18-45  years,  met  both  the  primary  and  secondary  endpoints.  The  primary  endpoint  of  CONSTANT  study  was  directed  to  the
manufacturing  consistency  of  Sci-B-Vac.  For  this  primary  endpoint,  the  study  evaluated  the  vaccine  immune  response,  as  measured  by  geometric  mean
concentration  (“GMC”)  of  antibodies  across  three  independent,  consecutively-manufactured  lots  of  Sci-B-Vac,  four  weeks  after  the  third  vaccination.
Together with the positive safety and immunogenicity results of the PROTECT Phase III study, we expect these data to comprise the basis for the regulatory
submissions in the United States, Europe, and Canada.

A secondary endpoint of the CONSTANT study demonstrated non-inferiority of SPR of Sci-B-Vac (99.3%) vs. Engerix-B (94.8%), one month after
completion of the full course of vaccination (SPR difference: 4.49%; 95% CI [2.90%, 6.63%] – up from 90.4% for Sci-B-Vac and 51.6% for Engerix-B at day
168, after only two vaccinations. In addition to demonstrating non-inferiority, the SPR achieved with Sci-B-Vac compared to Engerix-B was higher after both
two  and  three  vaccinations.  An  exploratory  analysis  in  CONSTANT  also  compared  the  SPR  after  two  doses  of  Sci-B-Vac  (90.4%)  to  the  SPR  after  three
doses of Engerix-B (94.8%) (SPR difference: -4.3%; 95% CI [-6.48%, -1.90%]). As per the commonly-used statistical margin of non-inferiority for hepatitis
B vaccines, defined as the lower limit of the 95% CI being above -10%, this analysis demonstrated non-inferiority after two doses of Sci-B-Vac (at day 168)
compared with three doses of Engerix-B (at day 196). Similarly, at these time points, preliminary data from the integrated immunogenicity analysis of both
the PROTECT and CONSTANT studies in subjects age 18-45 years demonstrate a difference in SPR of -4.2%; 95% CI [-6.38%, -1.99%]. The two versus
three  dose  comparison  is  not  part  of  the  regulatory  approval  process  and  will  not  be  included  in  the  expected  indication  we  will  seek,  but  we  believe  it
contributes to the robust immunogenicity profile of Sci-B-Vac.

The safety and tolerability seen in CONSTANT and PROTECT studies were consistent with the known safety profile of Sci-B-Vac. No new safety
risks  were  identified,  and  no  safety  signals  were  observed  in  either  study  cohort.  The  integrated  safety  data  analysis  from  both  the  PROTECT  and
CONSTANT studies is underway.

The  completed  Phase  III  studies  are  expected  to  support  the  Biologics  License  Application  (“BLA”)  to  the  FDA,  the  Marketing  Authorization
Application (“MAA”) to the EMA and the New Drug Submission (“NDS”) to Health Canada. We plan to submit applications for regulatory approvals in the
United States, Europe and Canada beginning in the fourth quarter of 2020.

VBI-2601: Hepatitis B Immunotherapeutic Candidate

VBI-2601 (BRII-179) is our novel, recombinant, protein-based immunotherapeutic candidate in development for the treatment of chronic hepatitis B
infection, a disease that affects more than 250 million people worldwide. Chronic hepatitis B infection can lead to cirrhosis of the liver, hepatocellular cancer,
and other liver disease, making it a life-threatening global health problem. VBI-2601 (BRII-179) is formulated to induce broad immunity against hepatitis B
virus, including T-cell immunity which plays an important role in controlling hepatitis B infection.

On December 6, 2018, the Company announced that it had entered into a Collaboration and License Agreement (“License Agreement”) with Brii
Bio, pursuant to which, among other things, subject to terms and conditions set forth in the License Agreement, we and Brii Bio agreed to collaborate on the
development of a hepatitis B recombinant protein-based immunotherapeutic candidate in China, Hong Kong, Taiwan and Macau (the “Licensed Territory”),
and to conduct a Phase Ib/IIa collaboration clinical trial for the purpose of comparing VBI-2601 (BRII-179) with a novel composition developed jointly with
Brii Bio.

On November 14, 2019, we announced initiation of enrollment in a Phase Ib/IIa Study of VBI-2601 (BRII-179) in patients with chronic hepatitis B
infection. The Phase Ib/IIa clinical study of VBI-2601 (BRII-179) is a randomized, controlled study designed to assess the safety, tolerability, antiviral and
immunological  activity  of  VBI-2601  (BRII-179).  The  study  is  designed  as  a  two-part  dose-escalation  study  assessing  different  dose  levels  of  VBI-2601
(BRII-179)  with  and  without  an  immunomodulatory  adjuvant,  and  is  expected  to  enroll  up  to  65  patients.  Initial  human  proof-of-concept  data  from  the
clinical study is anticipated in the second half of 2020. The study is sponsored by Brii Bio and will be conducted at multiple study sites in New Zealand,
Australia, Thailand, South Korea, Hong Kong SAR, and China.

eVLP Platform

The eVLP technology enables the synthetic manufacture of an “enveloped” virus-like particle, or “eVLP”. Many viruses are “enveloped” in that they
are  surrounded  by  a  lipid  bilayer  membrane.  Such  viruses  display  antigenic  proteins  on  the  surface  of  their  “envelope”  which  can  be  targets  for  vaccine
development. The ability to synthetically manufacture an “enveloped” virus-like particle is different from previously developed VLP technologies, which did
not include the lipid bilayer membrane, and thus these technologies were unable to express antigenic proteins within an “envelope” as they occur in nature.

VBI-1901: Cancer Vaccine Immunotherapeutic Candidate

Our GBM brain cancer vaccine immunotherapeutic program, VBI-1901, targets CMV proteins present in GBM tumor cells. CMV is associated with
a number of other solid tumors in addition to GBM, including breast cancer and pediatric medulloblastoma. We initiated dosing in a multi-center Phase I/IIa
clinical study evaluating VBI-1901, in combination with granulocyte-macrophage colony stimulating factor (“GM-CSF”), in patients with recurrent GBM in
January 2018. Enrollment in Part A of the study was completed in December 2018. In April 2019, the independent data safety monitoring board completed
reviews of all safety data from our fully-enrolled Part A portion of the Phase I/IIa trial in recurrent GBM subjects, which included 6 subjects in each of 3
different dose cohorts. The data safety monitoring board unanimously recommended the continuation of the study without modification and had no safety
concerns about any of the 3 dose levels of VBI-1901. On April 23, 2019, we announced that, based on safety and immunogenicity data, the highest dose
tested in Part A of the ongoing Phase I/IIa study in recurrent GBM patients, 10µg, was selected as the optimal dose level to test in Part B of the study. Where
Part  A  was  designed  as  a  dose-escalation  phase  to  assess  safety,  tolerability,  and  to  define  the  optimal  dose  level  of  VBI-1901,  Part  B  is  a  subsequent
extension phase of the optimal dose level defined in Part A.

On September 10, 2019, we entered into a Clinical Collaboration Agreement (“Collaboration Agreement”) with GlaxoSmithKline Biologicals S.A.
(“GSK”) pursuant to which we will investigate the use of GSK’s proprietary AS01B adjuvant system in our ongoing study of VBI-1901. As a result of the
Collaboration  Agreement,  a  second  study  arm  was  added  to  Part  B  of  the  ongoing  Phase  I/IIa  clinical  study.  Part  B  is  now  a  two-arm  open-label  study,
enrolling 20 first recurrent GBM patients to receive VBI-1901 in combination with either granulocyte-macrophage colony-stimulating factor (“GM-CSF”) or
AS01B as immunomodulatory adjuvants. Enrollment of the 10 patients in the VBI-1901 with GM-CSF arm was initiated at the end of July 2019. Initiation of
enrollment of the 10 patients in the VBI-1901 with AS01B was announced in March 2020.

Safety, immunologic responses, and clinical and tumor responses from the VBI-1901 with GM-CSF in Part A and in the GM-CSF arm of Part B of
the  study  were  announced  throughout  2019  and  early  2020,  respectively.  VBI-1901  continues  to  be  well-tolerated,  with  no  vaccine-related  safety  signals
observed. In the high-dose cohort of Part A, vaccine response correlated with tumor response, with all three vaccine responders demonstrating stable disease
(“SD”) for greater than 12 weeks. Two patients in the high-dose cohort of Part A experienced a 60% reduction in the size of primary tumor – VBI-1901 also
induced and expanded robust T cell responses in these two patients. For patients who were vaccines responders, the 12-month overall survival (“OS”) rate
was 83% (n = 5/6), compared to 33% (n = 3/9) for vaccine non-responders. Similarly, among patients evaluable for response and survival in Part A, vaccine
responders saw a 6.25-month improvement in median OS (14.0 months) compared to vaccine non-responders (7.75 months). VBI-1901 continues to be safe
and well tolerated at al doses tested, with no safety signals observed.

Based on the data announced in November 2019, the early the tumor and immunologic responses seen in Part B appear similar to the responses and
observed  in  Part  A  of  the  study.  Correlations  between  immunologic  biomarkers  and  tumor/clinical  responses  will  continue  to  be  refined  throughout  the
duration of Part B of the study.

We expect expanded immunologic data and tumor imaging data from the VBI-1901 with GM-CSF arm in Part B of the study in the first half of

2020.

VBI-1501: Prophylactic CMV Vaccine Candidate

Another of our eVLP programs is a vaccine candidate that aims to prevent CMV infections. CMV may cause severe infections in newborn children
(congenital CMV) and may also cause serious infections in people with weakened immune systems, such as solid organ or bone marrow transplant recipients.
Our prophylactic CMV vaccine candidate uses the eVLP platform to express a modified form of the CMV glycoprotein B (“gB”) antigen, and is adjuvanted
with alum, an adjuvant used in FDA-approved products.

In May 2018, we announced positive top-line results from the randomized, placebo-controlled Phase I study of VBI-1501. The final Phase I study
results demonstrated that VBI-1501 was safe and well-tolerated at all doses, with and without the adjuvant alum. The highest dose of VBI-1501, 2.0µg, with
alum, elicited CMV-neutralizing antibodies against fibroblast cell infection in 100% of subjects after the third vaccination, up from 81% of subjects after the
second  vaccination,  inducing  titers  comparable  to  those  observed  in  patients  protected  as  a  result  of  natural  infection.  Neutralizing  antibodies  against
epithelial cell infection were also seen in 31% of subjects after the third vaccination of VBI-1501 2.0µg with alum. The data also showed the formulation of
the vaccine with alum enhanced antibody titers. The highest dose of VBI-1501 tested, 2.0µg with alum, contains approximately 10-fold less antigen content
than that used in several other VLP-based vaccines or in previous CMV vaccine candidates developed by other companies.

On December 20, 2018 we announced plans for a Phase II clinical study evaluating VBI-1501 following positive discussions with Health Canada. We
received similarly positive guidance from the FDA in July 2019. The Phase II study is expected to assess the safety and immunogenicity of dosages of VBI-
1501 up to 20µg with alum. The Company is currently evaluating the timing of next steps for the program.

We  may  also  seek  to  in-license  clinical-stage  vaccines  or  vaccine-related  technologies  that  we  believe  complement  our  product  and  pipeline

portfolio, in addition to technologies that may supplement our therapeutic vaccination efforts in immuno-oncology.

58

 
 
 
 
 
 
 
At present, our operations are focused on:

● preparing marketing authorization applications for Sci-B-Vac in the United States, Europe and Canada;

● preparing  for  commercialization  of  Sci-B-Vac  in  additional  markets,  including  the  United  States,  Europe,  and  Canada,  where  we  may  obtain

regulatory approval;

● conducting the Phase I/IIa clinical study of our GBM vaccine immunotherapeutic candidate, VBI-1901;

● developing VBI-2601  (BRII-179),  our  protein-based  immunotherapeutic  candidate  for  treatment  of  chronic  hepatitis  B,  in  collaboration  with  Brii

Bio;

● preparation for further development of VBI-1501, our preventative CMV vaccine candidate, into the next phase of development;

● ensuring our recently modernized manufacturing facility in Rehovot, Israel obtains all required regulatory approvals;

● increasing sales of Sci-B-Vac in territories where it is currently registered or available on a named-patient basis;

● continuing  the  research  and  development  (“R&D”)  of  our  pipeline  candidates,  including  the  exploration  and  development  of  new  pipeline

candidates,

● implementing operational, financial and management information systems, including through third party partners, to support our commercialization

activities;

● maintaining, expanding and protecting our intellectual property portfolio; and

● developing our internal systems and processes for regulatory affairs and compliance.

VBI’s revenue generating activities have been the sale of Sci-B-Vac product in markets where it is approved or on a named patient basis where it is
not  approved,  though  those  markets  have  generated  a  limited  number  of  sales  to-date,  various  business  development  transactions,  and  R&D  services
generating  fees.  VBI  has  incurred  significant  net  losses  and  negative  operating  cash  flows  since  inception  and  expects  to  continue  incurring  losses  and
negative  cash  flows  from  operations  as  we  carry  out  our  planned  clinical,  regulatory,  R&D,  sales  and  manufacturing  activities  with  respect  to  the
advancement of our Sci-B-Vac and new pipeline candidates. As of December 31, 2019, VBI had an accumulated deficit of approximately $262.4 million and
stockholders’  equity  of  approximately  $88.3  million.  Our  ability  to  maintain  our  status  as  an  operating  company  and  to  realize  our  investment  in  our  In-
Process Research and Development (“IPR&D”) assets is dependent upon obtaining adequate cash to finance our clinical development, manufacturing, our
administrative overhead and our research and development activities, and ultimately to profitably monetize our IPR&D. We plan to finance future operations
with existing cash reserves. We expect that we will need to secure additional financing to finance our business plans, which may be a combination of proceeds
from  the  issuance  of  equity  securities,  the  issuance  of  additional  debt,  structured  asset  financings  and  revenues  from  potential  business  development
transactions, if any. There is no assurance the Company will manage to obtain these sources of financing, if required. These factors raise substantial doubt
about the Company’s ability to continue as a going concern. The accompanying financial statements have been prepared assuming that we will continue as a
going concern. The financial statements do not include any adjustments to reflect the possible future effects on the recoverability and classification of assets
or the amounts and classifications of liabilities that may result should we be unable to continue as a going concern.

We have incurred operating losses since inception, have not generated significant product sales revenue and have not achieved profitable operations.
We incurred net losses of $54.8 million for the year ended December 31, 2019 and we expect to continue to incur losses in future periods. We anticipate that
we  will  continue  to  incur  operating  expenses  as  we  continue  our  research  and  development,  clinical  studies  and  as  we  take  steps  to  commercialize  our
product. These include expenses related to:

● preparing marketing authorization applications for Sci-B-Vac in the United States, Europe and Canada;

● preparing for commercialization and commercialization of Sci-B-Vac in additional markets, including the United States, Europe, and Canada, where

we may obtain approval;

● continuing  the  research  and  development  of  our  pipeline  candidates,  including  further  development  of  VBI-1901,  our  cancer  vaccine
immunotherapeutic candidate, VBI-2601 (BRII-179), our hepatitis B immunotherapeutic candidate, and VBI-1501, our prophylactic CMV vaccine
candidate;

● manufacturing, obtaining and maintaining required regulatory approvals at our recently modernized manufacturing facility in Rehovot, Israel;

● maintaining, expanding and protecting our intellectual property portfolio;

● hiring additional clinical, manufacturing, and scientific personnel or contractors; and

● implementing operational, financial and management information systems and adding human resources support, including additional personnel, to

support our product development; and

● developing our internal systems and processes for regulatory affairs and compliance.

In addition, we have incurred and will continue to incur significant expenses as a public company, which subjects us to the reporting requirements of the
Securities Exchange Act of 1934, as amended (the “Exchange Act”), the Sarbanes-Oxley Act and the rules and regulations of the NASDAQ Capital Market
and the Canadian securities regulators.

Amended Credit Facility

In  2016,  the  Company  through  VBI  DE  assumed  a  term  loan  facility  with  Perceptive  Credit  Holdings,  LP,  a  related  party,  (the  “Lender”)  in  the
amount  of  $6,000  (the  “Facility”).  On  December  6,  2016,  the  Company  amended  the  Facility  (the  “Amended  Credit  Facility”)  and  raised  the  Lender’s
commitment amount to $13,200, which was combined with the remaining balance from the Facility of $1,800. On July 17, 2018, the Company amended the
Amended Credit Facility by the Second Amendment to extend the period the Company is required to pay only the interest on the loan from May 31, 2018 to
December 31, 2018 and to extend the expiration date of certain warrants to purchase 363,771 common shares issued to the Lender with an original issue date
of July 25, 2014, from July 25, 2019 to December 6, 2021. The Company accounted for this as a debt modification, and as a result of the extension of the
warrant expiration date in connection with the Second Amendment, the debt discount was increased by $386. This amount represents the incremental fair
value of the modified warrants. On January 31, 2019 we further amended the Amended Credit Facility by the Third Amendment to i) extend the period we are
required to pay only the interest on the loan from December 31, 2018 to January 31, 2020; ii) to extend the maturity date of the term loan from December 31,
2019 to June 30, 2020 and iii) reduce the exercise price of certain warrants to purchase common shares issued to the Lender to $2.75 from $4.13 for 363,771
warrants issued on July 25, 2014 and for 363,771 warrants issued on December 6, 2016 and from $3.355 for 1,341,282 warrants issued on December 6, 2016.

Research and Development Services

Pursuant to an agreement with the Israel Innovation Authority (formerly the Office of the Chief Scientist of Israel), the Company is required to make
services  available  for  the  biotechnology  industry  in  Israel.  These  services  include  relevant  activities  for  development  and  manufacturing  of  therapeutic
proteins according to international standards and GMP quality level suitable for toxicological studies in animals and clinical studies (Phase I & II) in humans.
Service activities include analytics/bio analytics methods for development and process development of therapeutic proteins starting with a candidate clone
through the upstream, purification, formulation and filling processes and manufacturing for Phase I & II clinical trials.

These R&D services are primarily marketed to the Israeli research community in academia and Israeli biotechnology companies in the life sciences
lacking the infrastructure or experience in the development and production of therapeutic proteins to the standards and quality required for clinical trials for
human  use.  During  the  year  ended  December  31,  2019,  the  Company  provided  services  to  biotechnology  companies  including  analytical  development,
upstream development process, protein purification and formulation and filling for Phase I clinical studies.

In addition, pursuant to the License Agreement with Brii Bio we provide R&D services to Brii Bio as part of the development of VBI-2601 (BRII-

179).

Modernization and Capacity Increase of Our Manufacturing Facility

In 2018, we temporarily closed our manufacturing facility in Rehovot, Israel, for modernization and capacity increase. We re-commenced operations
in May 2019 and the review of the modernization and the capacity increase by the IMoH occurred in December of 2019. We received our certificate of Good
Manufacturing Practice (“GMP”) compliance from the IMoH on January 27, 2020. In addition to the GMP compliance certification, the IMoH will also need
to review and approve the process validation submission and provide approval for us to sell Sci-B-Vac manufactured at the modernized facility. We increased
the capacity of our manufacturing facility to be able to supply commercial quantities of Sci-B-Vac upon FDA, and/or EMA and/or Health Canada approval
and to supply clinical materials of VBI-2601 (BRII-179).

Third Party License and Assignment Agreements

We currently are dependent on licenses from third parties for certain of our key technologies, including the license granted under the Ferring License
Agreement and the license from the L’Universite Pierre et Marie Curie (“UPMC”). Under the Ferring License Agreement, we are committed to pay Ferring
royalties equal to 7% of net sales (as defined therein) of HBsAg “Product” (as defined therein). Under the SciGen Assignment Agreement, we are required to
pay royalties to SciGen Ltd. equal to 5% of net sales (as defined in the Ferring License Agreement) of Product. Under the Ferring License Agreement and the
SciGen Assignment Agreement, we originally were to pay royalties on a country-by-country basis until the date 10 years after the date of commencement of
the first royalty year in respect of such country. In April 2019, we exercised our option to extend the Ferring License Agreement in respect of all the countries
that still make up the territory for an additional 7 years by making a one-time payment to Ferring of $100. Royalties under the Ferring License Agreement and
SciGen Assignment Agreement will continue to be payable for the duration of the extended license periods. Under our license agreement with UPMC and
other licensors relating to eVLP technology, we have an exclusive license to a family of patents that is expected to expire in the United States in 2022 and
2021 in other countries. Under this agreement, we are required to pay UPMC between 0.75% to 1.75% of net sales and certain lump-sum milestone payments.
UPMC is also a co-owner of the patent family covering our VBI-1501 CMV vaccine and we are currently negotiating extension of our existing license to
cover this patent family.

NASDAQ Minimum Bid Price Requirement

As  previously  reported,  on  August  14,  2019,  we  received  a  letter  from  the  Listing  Qualifications  Department  of  the  Nasdaq  Stock  Market  (“NASDAQ”)
indicating that, based upon the closing bid price of our common shares for the 30 consecutive business day period between July 2, 2019 through August 13,
2019,  we  did  not  meet  the  minimum  bid  price  of  $1.00  per  share  required  for  continued  listing  on  The  NASDAQ  Capital  Market  pursuant  to  NASDAQ
Listing Rule 5550(a)(2). The letter also indicated that we would be provided with a compliance period of 180 calendar days, or until February 10, 2020 (the
“Compliance  Period”),  in  which  to  regain  compliance  pursuant  to  NASDAQ  Listing  Rule  5810(c)(3)(A).  In  order  to  regain  compliance  with  NASDAQ’s
minimum bid price requirement, our common shares were required to maintain a minimum closing bid price of $1.00 for at least ten consecutive business
days during the Compliance Period. On January 9, 2020, we received notice from the NASDAQ indicating that the Company has regained compliance with
the minimum bid price requirement under Nasdaq Listing Rule 5550(a)(2), and the matter is now closed.

Financial Overview

Overall Performance

The Company had net losses of approximately $54.8 million and $63.6 million for the years ended December 31, 2019, and 2018, respectively. The
Company  has  an  accumulated  deficit  of  $262.4  million  as  December  31,  2019.  The  Company  had  $44.2  million  of  cash  at  December  31,  2019  and  net
working capital of approximately $17.2 million.

Revenues

Revenues consist primarily of R&D services revenue recognized as part of the License Agreement with Brii Bio. Other revenues relate to the sale of

products and services.

Cost of revenues

Cost  of  revenues  consist  primarily  of  costs  incurred  for  manufacturing  the  Sci-B-Vac  vaccine,  which  includes  cost  of  materials,  consumables,
supplies,  contractors  and  manufacturing  salaries.  Certain  cost  of  revenues  related  to  the  temporary  closure  of  the  manufacturing  facility,  during  the
modernization and capacity increase, of approximately $348 was allocated to general and administrative expenses in the year ended December 31, 2019.

62

 
 
 
 
 
 
 
 
 
 
 
Research and Development Expenses

R&D expenses consist primarily of costs incurred for the development of Sci-B-Vac, VBI-1901, our GBM vaccine immunotherapeutic candidate,

and VBI-1501, our CMV candidate which include:

● the cost of acquiring, developing and manufacturing clinical study materials and other consumables and lab supplies used in our pre-clinical studies;

● expenses incurred  under  agreements  with  contractors  or  contract  manufacturing  organizations  or  CROs  to  advance  the  vaccines  into  and  through

completion of clinical studies; and

● employee-related expenses, including salaries, benefits, travel and stock-based compensation expense.

We expense R&D costs when we incur them.

General and Administration Expenses

General and administration expenses (“G&A”) consist principally of salaries and related costs for executive and other administrative personnel and
consultants, including stock-based compensation, and travel expenses. Other G&A expenses include professional fees for legal, patent protection, consulting
and accounting services, travel and conference fees, including board, rent, maintenance of facilities, depreciation, office supplies and expenses, insurance and
other general expenses. G&A expenses are expensed when incurred.

We  expect  that  our  G&A  expenses  will  increase  in  the  future  as  a  result  of  adding  employees  and  scaling  our  operations  commensurate  with
advancing clinical candidates and continuing to support a public company infrastructure. These increases will likely include increased costs for insurance,
hiring of additional personnel, board committees, outside consultants, investor relations, lawyers and accountants, among other expenses.

Impairment Charges

Impairment  charges  consist  of  impairment  on  intangible  assets  and  goodwill,  if  any.  See  Note  6  of  the  Notes  to  the  Consolidated  Financial

Statements.

Interest Income

Interest income consists principally of interest income earned on cash balances.

Interest Expense

Interest expense is associated with our credit facility as discussed in Note 9 of the Notes to the Consolidated Financial Statements.

Revenue for the year ended December 31, 2019 was $2,221 as compared to $3,355 for the year ended December 31, 2018. The revenue decreased by
$1,134 or 34%, as a result of the license revenue earned as part of the License Agreement with Brii Bio in the year ended December 31, 2018 with no similar
transaction  in  the  year  ended  December  31,  2019,  offset  by  increased  R&D  services  revenue  as  part  of  the  License  Agreement  with  Brii  Bio  for  the  year
ended December 31, 2019. The decrease in revenue was also due to decreased product sales in Europe in the year ended December 31, 2019 due to reduced
named-patient sales.

Cost of revenues for the year ended December 31, 2019 was $7,904 as compared to $4,509 for the year ended December 31, 2018. The increase in
the cost of revenues of $3,395, or 75%, was due to cost of revenue related to the License Agreement with Brii Bio during the year ended December 31, 2019
of $1,141, which did not occur during the year ended December 31, 2018; the net increase related to the reclassification of certain costs of revenues to G&A
expenses during the year ended December 31, 2018, which were not as significant in the year ended December 31, 2019 of $372; and the re-commencement
of manufacturing subsequent to the temporary closure of our manufacturing facility in Rehovot, Israel which occurred in the second quarter of 2019.

Research and Development Expenses

R&D expenses for the year ended December 31, 2019 were $26,332 as compared to $38,467 for the year ended December 31, 2018. The decrease in
R&D expenses of $12,135, or 32%, was primarily due to a decrease in the costs related to the Sci-B-Vac Phase III clinical studies and our GBM vaccine
immunotherapeutic candidate clinical study. With regard to the Sci-B-Vac clinical studies, we announced top-line results for the Sci-B-Vac CONSTANT study
in January 2020 and completed the Sci-B-Vac PROTECT study during the second quarter of 2019, as compared to the year ended December 31, 2018, during
which period both studies were ongoing. For the GBM vaccine immunotherapeutic, there were fewer patients on trial for the year ended December 31, 2019
compared to year ended December 31, 2018 as only the high dose cohort of Part A of the Phase I/IIa study was ongoing and Part B of the Phase I/IIa study

December 31, 2019 compared to the year ended December 31, 2018.

General and Administration

G&A  expenses  for  the  year  ended  December  31,  2019  were  $14,092  as  compared  to  $20,509  for  the  year  ended  December  31,  2018.  The  G&A
expense decrease of $6,417, or 31%, was primarily due to a $6 million payment made to re-obtain distribution rights in Asia during the year ended December
31,  2018  with  no  similar  payment  made  during  the  year  ended  December  31,  2019.  Other  variances  include  decreased  administrative  expenses  and  the
allocation to G&A expenses of certain costs of revenues related to the temporary facility closure, as discussed above in “Cost of Revenues”.

Impairment Charges

Impairment charges for the year ended December 31, 2019 were $6,292 as compared to $278 for the year ended December 31, 2018. There was an
impairment charge for the year ended December 31, 2019 related to goodwill of $6,292 as compared to the impairment charge on property and equipment of
$278 for the year ended December 31, 2018.

Net Loss from Operations

Net loss from operations for the year ended December 31, 2019 was $52,399 as compared to $60,408 for the year ended December 31, 2018. The
$8,009 decrease in the net loss from operations resulted from the increased cost of revenues and impairment charges offset by decreased R&D expenses and
G&A expenses as discussed above.

Interest Expense, Net of Interest Income

Interest expense, net of interest income, decreased by $436 as a result of decreased amortization of the debt discount as a result of the debt extension
from December 31, 2019 to June 30, 2020 offset by increased interest income earned on cash balances during the year ended December 31, 2019, compared
to interest earned during the year ended December 31, 2018.

Foreign Exchange Loss

Foreign exchange loss for the year ended December 31, 2019 was $218 compared to a foreign exchange loss of $560 for the year ended December

31, 2018. The change is a result of the changes in the exchange rate in which the foreign currency transactions were denominated for each of those periods.

Income Tax Expense

We did not incur any income tax expense for the year ended December 31, 2018 and for the year ended December 31, 2019.

Net Loss

The net loss decreased by $8,787, or 14%, from $63,600 for the year ended December 31, 2018 to $54,813 for the year ended December 31, 2019.

The decrease in net loss is mainly attributable to the decrease in net loss from operations, discussed above.

As of December 31, 2019, we had cash of $44,213 as compared to $59,270 as of December 31, 2018. As of December 31, 2019, the Company had
working capital of $17,206 as compared to working capital of $38,354 at December 31, 2018. Working capital is calculated by subtracting current liabilities
from current assets.

We  expect  that  we  will  need  to  secure  additional  financing  in  the  future  to  carry  out  all  of  our  planned  clinical,  regulatory,  R&D,  sales  and
manufacturing activities with respect to the advancement of our Sci-B-Vac and new pipeline candidates. We base this belief on assumptions that are subject to
change, and we may be required to use our available cash resources sooner than we currently expect. The Company expects to re-finance the current term
loan obligations and secure additional funds in order to continue its ongoing development programs. The additional funds may be a combination of proceeds
from  the  issuance  of  equity  securities,  the  issuance  of  additional  debt,  structured  asset  financings  or  revenues  from  potential  business  development
transactions, and may require that additional warrants be issued. To date, the Company has been able to obtain financing as and when it was needed; however,
there is no assurance that financing will be available in the future, or if it is, that it will be available at acceptable terms.

The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern; however, the
above conditions raise substantial doubt about the Company’s ability to do so. The consolidated financial statements do not include any adjustments to reflect
the possible future effects on the recoverability and classification of assets or the amounts and classifications of liabilities that may result should the Company
be unable to continue as a going concern. The Company’s long-term success and ability to continue as a going concern is dependent upon obtaining sufficient
capital  to  fund  our  planned  clinical,  regulatory,  and  research  and  development  of  our  products  and  pipeline  candidates,  to  bring  about  their  successful
commercial release, to generate revenue and, ultimately, to attain profitable operations or, alternatively, to advance its products and technology to such a point
that they would be attractive candidates for acquisition by others in the industry.

In  September  2019,  we  received  aggregate  gross  proceeds  of  $40.25  million  from  an  underwritten  public  offering  of  an  aggregate  of  80,500,000
common  shares  at  a  price  of  $0.50  per  share.  After  deducting  the  underwriting  discounts  and  commissions  and  offering  expenses,  net  proceeds  from  the
offering were $37.4 million. Net proceeds from the offering are being used to support our pipeline programs, to continue the advancement of our clinical
development and research programs and for other general corporate purposes.

On December 17, 2018, we closed an underwritten public offering of an aggregate of 30,665,304 common shares at a price of $1.40 per share for
total gross proceeds of $42.9 million. The Company incurred $3.1 million of issuance costs related to the offering resulting in net cash proceeds of $39.8
million.

On  December  4,  2018,  we  entered  into  the  License  Agreement  with  Brii  Bio,  whereby  we  received  a  total  upfront  payment  of  $11  million  to
collaborate on the development of a hepatitis B recombinant protein based immunotherapeutic in China, Hong Kong, Taiwan and Macau and to conduct a
Phase  II  collaboration  clinical  trial.  The  License  Agreement  specified  an  allocation  of  $7  million  of  this  amount  as  an  equity  investment  in  exchange  for
2,295,082 common shares. The License Agreement set forth a price of $3.05 per share which was at a premium to the closing market price of $1.58 on the
day  of  issuance,  resulting  in  actual  allocation  of  the  fair  value  of  the  2,295,082  shares  being  $3.6  million.  The  remaining  $7.4  million  of  the  $11  million
consideration received was allocated to the sale of the license and research and development services.

Our actual future capital requirements will depend on many factors, including the progress and results of our clinical trials, the duration and cost of
discovery and preclinical development, laboratory testing and clinical trials for our products, the timing and outcome of regulatory review of our products,
product sales outside of Israel, the costs involved in preparing, filing, prosecuting, maintaining, defending and enforcing patent claims and other intellectual
property rights, the number and development requirements of other pipeline candidates that we pursue and the costs of commercialization activities, including
product marketing, sales and distribution.

The Company will require significant additional funds to conduct clinical and non-clinical trials, achieve regulatory approvals, and, subject to such
approvals, commercially launch its products and will need to secure additional financing in the future to support our operations and to realize our investment
in our IPR&D assets.

We  expect  to  finance  our  future  cash  needs  through  public  or  private  equity  offerings,  debt  financings  or  structured  asset  financings,  or  business
development  transactions.  Although  we  are  pursuing  different  opportunities,  other  than  as  disclosed  in  this  report,  we  currently  do  not  have  any  signed
commitments for future external funding. We may need to raise additional funds more quickly if one or more of our assumptions prove to be incorrect or if we
choose to expand our product development efforts more rapidly than we presently anticipate. We may also decide to raise additional funds even before we
need  them  if  the  conditions  for  raising  capital  are  favorable.  Additional  equity  or  debt  or  structured  asset  financing,  grants  or  business  development
transactions  may  not  be  available  on  acceptable  terms,  if  at  all.  If  adequate  funds  are  not  available,  we  may  be  required  to  delay,  reduce  the  scope  of  or
eliminate  our  R&D  programs,  reduce  our  planned  commercialization  efforts  or  obtain  funds  through  arrangements  with  collaborators  or  others  that  may
require us to relinquish rights to certain pipeline candidates that we might otherwise seek to develop or commercialize independently.

To the extent we raise additional capital by issuing equity securities or obtaining borrowings convertible into equity, ownership dilution to existing
stockholders will result and future investors may be granted rights superior to those of existing stockholders. The incurrence of indebtedness or debt financing
would result in increased fixed obligations and could also result in covenants that would restrict our operations. Our ability to obtain additional capital may
depend on prevailing economic conditions and financial, business and other factors beyond our control. The unstable economic environment in Europe, and
disruptions in the United States and global financial markets may adversely impact the availability and cost of credit, as well as our ability to raise money in
the  capital  markets.  Current  economic  conditions  have  been,  and  continue  to  be,  volatile.  Continued  instability  in  these  market  conditions  may  limit  our
ability to access the capital necessary to fund and grow our business.

Year Ended December 31, 2019 Compared to the Year Ended December 31, 2018

Net cash flows used in Operating Activities

The Company incurred net losses of $54,813 and $63,600 in the years ended December 31, 2019 and 2018, respectively. The Company used $48,712
and $45,533 in cash for operating activities during the years ended December 31, 2019 and 2018, respectively. The increase in cash outflows is largely as a
result of an increase in net changes in working capital items, specifically accounts payable, other current liabilities and deferred revenue.

Net cash flows used in Investing Activities

The  Company’s  net  cash  used  in  investing  activities  for  the  year  ended  December  31,  2019  consisted  primarily  of  the  purchase  of  property  and
equipment in SciVac as part of the modernization and capacity increase of the manufacturing facility. Our net cash used in investing activities for the year
ended December 31, 2019 consisted of purchases of equipment of $3,673 compared to purchases of equipment of $5,993 for the year ended December 31,
2018.

Net cash flows provided by Financing Activities

Cash flows provided by financing activities decreased by $6,202, from $43,617 for the year ended December 31, 2018 to $37,415 for the year ended
December 31, 2019. In 2019, the Company closed an underwritten public offering for gross proceeds of $40,250 offset by $2,835 of share issuance costs.
During the year ended December 31, 2018 the Company received $46,558 from the proceeds from the issuance of common shares for cash offset by $3,006
of cash issuance costs.

Off-Balance Sheet Arrangements

The  Company  has  no  off-balance  sheet  transactions,  arrangements,  obligations  (including  contingent  obligations),  or  other  relationships  with
unconsolidated  entities  or  other  persons  that  have,  or  may  have,  a  material  effect  on  our  financial  condition,  changes  in  financial  condition,  revenues  or
expenses, results of operations, liquidity, capital expenditures or capital resources.

Net Operating Loss Carryforwards

At  December  31,  2019,  the  Company  had  net  operating  loss  carryovers  (“NOL’s”)  aggregating  approximately  $218.9  million.  The  NOL’s  are

NOL and tax credit carryforwards are subject to review and possible adjustment by the tax authorities in the respective countries. This could limit the
amount of tax attributes that can be utilized annually to offset future taxable income or tax liabilities. At December 31, 2019, we recorded a 100% valuation
allowance against our NOL, as we believe it is more likely than not that the tax benefits will not be fully realized. In the future, if we determine that a portion
or all of the tax benefits associated with our tax carryforwards will be realized, net income would increase in the period of determination.

Critical Accounting Policies and Estimates

Critical accounting policies are those that are most important to the portrayal of our financial condition and results of operations and require difficult,
subjective and complex judgments by management in order to make estimates about the effect of matters that are inherently uncertain. During the year ended
December  31,  2019,  there  were  no  significant  changes  to  our  critical  accounting  policies,  which  are  discussed  in  Note  2  to  our  Consolidated  Financial
Statements.

Preparation  of  the  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 and disclosure of contingent
assets  and  liabilities  at  the  date  of  the  consolidated  financial  statements  and  the  reported  amounts  of  revenues  and  expenses  during  the  reporting  period.
Actual amounts could differ from the estimates made. We continually evaluate estimates used in the preparation of the consolidated financial statements for
reasonableness. Appropriate adjustments, if any, to the estimates used are made prospectively based upon such periodic evaluation.

In  particular,  significant  judgments  made  by  management  in  the  application  of  U.S.  GAAP  during  the  preparation  of  the  consolidated  financial

statements and estimates with a risk of material adjustment include:

70

 
 
 
 
 
 
Revenue Recognition

We recognize revenue when we transfer promised goods or services to customers in an amount that reflects the consideration to which we expect to
be entitled in exchange for those goods or services. To determine revenue recognition for contracts with customers we perform the following five steps: (i)
identify  the  contract(s)  with  a  customer;  (ii)  identify  the  performance  obligation(s)  in  the  contract;  (iii)  determine  the  transaction  price;  (iv)  allocate  the
transaction price to the performance obligation(s) in the contract; and (v) recognize revenue when (or as) we satisfy the performance obligation(s). At contract
inception, we assess the goods or services promised within each contract, assess whether each promised good or service is distinct and identify those that are
performance obligations.

The  Company  must  use  significant  judgment  to  determine:  a)  the  number  of  performance  obligations  based  on  the  determination  under  step  (ii)
above  and  whether  those  performance  obligations  are  distinct  from  other  performance  obligations  in  the  contract;  b)  the  transaction  price  under  step  (iii)
above; and c) the stand-alone selling price for each performance obligation identified in the contract for the allocation of transaction price in step (iv) above.
The Company uses judgment to determine whether milestones or other variable consideration, except for royalties, should be included in the transaction price.
The transaction price is allocated to each performance obligation on an estimated stand-alone selling price basis, for which the Company recognizes revenue
as or when the performance obligations under the contract are satisfied.

Where a portion of non-refundable up-front fees or other payments received are allocated to continuing performance obligations under the terms of a
collaborative arrangement, they are recorded as contract liabilities and recognized as revenue when (or as) the underlying performance obligation is satisfied.

Product Sales

The Company recognizes revenue from product sales when obligations under the terms of the contract with the customer are satisfied; this occurs

upon the transfer of control of the goods to the customers.

Collaborative Arrangements

The Company first evaluates license and/or collaboration arrangements to determine whether the arrangement (or part of the arrangement) represents
a collaborative arrangement pursuant to Accounting Standards Codification (“ASC”) Topic 808, Collaborative Arrangements (“ASC 808”), based on the risks
and rewards and activities of the parties pursuant to the contractual arrangement. The Company then determines if the collaborative arrangements are within
the scope of ASC Topic 606, Revenue Recognition (“ASC 606”).

Collaborative arrangements with partners which are within the scope of ASC 606 typically include payment to us of one of more of the following: (i)
license fees; (ii) R&D services to be performed as part of the contract; (iii) payments related to the achievement of developmental, regulatory, or commercial
milestones; and (iv) royalties on net sales of licensed products.

Collaborative arrangements (or elements within the contract that are deemed part of a collaborative arrangement) with partners which represent a

collaborative relationship and not a customer relationship, are accounted for outside the scope of ASC Topic 606.

License Fees

If  a  license  to  our  intellectual  property  is  determined  to  be  distinct  from  the  other  performance  obligations  identified  in  the  arrangement,  we
recognize revenues from non-refundable, up-front fees allocated to the license when the license is transferred to the licensee and the licensee is able to use
and benefit from the license.

R&D Services

The  promises  under  the  Company’s  collaboration  and  license  agreements  generally  include  R&D  services  to  be  performed  by  the  Company.  For
performance  obligations  that  include  R&D  services,  the  Company  generally  recognizes  revenue  allocated  to  such  performance  obligations  based  on  an
appropriate  measure  of  progress.  The  Company  utilizes  judgment  to  determine  the  appropriate  method  of  measuring  progress  for  purposes  of  recognizing
revenue, which is generally an input measure such as costs incurred. The Company evaluates the measure of progress each reporting period and, if necessary,
adjusts the measure of performance and related revenue recognition.

71

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Royalties

For  arrangements  that  include  sales-based  royalties,  including  milestone  payments  based  on  a  level  of  sales,  and  the  license  is  deemed  to  be  the
predominant item to which the royalties relate, the Company recognizes revenue at the later of (i) when the related sales occur or (ii) when the performance
obligation  to  which  some  or  all  of  the  royalty  has  been  allocated  has  been  satisfied  (or  partially  satisfied).  To  date,  the  Company  has  not  recognized  any
royalty revenue resulting from any of its licensing arrangements.

Income Taxes

In assessing the probability of realizing income tax assets, management makes estimates related to expectations of future taxable income, applicable
tax opportunities, expected timing of reversals of existing temporary differences and likelihood that tax positions taken will be sustained upon examination by
applicable tax authorities. The Company has recorded a full valuation allowance on its entire net deferred tax assets as it believes it is not more likely than not
the tax benefits will be realized.

Intangible Assets and Goodwill

Our intangible assets determined to have indefinite useful lives including In-Process Research and Development (“IPR&D”) and goodwill, are tested
for impairment annually, or more frequently if events or circumstances indicate that the assets might be impaired. Such circumstances could include but are
not limited to: (i) a significant adverse change in legal factors or in business climate, (ii) unanticipated competition, or (iii) an adverse action or assessment by
a regulator. The Company has established August 31st as the date for its annual impairment test of IPR&D and goodwill.

The Company’s IPR&D assets, which consist of CMV and GBM projects, were acquired in a business combination, capitalized as an intangible asset
and  are  tested  for  impairment  at  least  annually  until  commercialization,  after  which  time  the  IPR&D  is  amortized  over  its  estimated  useful  life.  The
impairment test compares the carrying amount of the IPR&D asset to its fair value. If the carrying amount exceeds the fair value of the asset, such excess is
recorded as an impairment loss. There was no IPR&D impairment determined as a result of the Company’s annual testing on August 31, 2019. The fair value
of the IPR&D assets included in the impairment test was determined using the income approach method and is considered Level 3 in the fair value hierarchy.
Some of the more significant estimates and assumptions inherent in the estimate of the fair value of IPR&D assets include the amount and timing of costs to
develop  the  IPR&D  into  viable  products,  the  amount  and  timing  of  future  cash  inflows,  the  discount  rate  and  the  probability  of  technical  and  regulatory
success applied to the cash flows. The discount rate used was 12.5% and the cumulative probability of technical and regulatory success to achieve approval to
market the products ranged from approximately 6% to 17%.

Goodwill represents the excess of the purchase price over the fair value of the net tangible and identifiable intangible assets acquired in a business
combination. When evaluating goodwill for impairment, we may first perform an assessment qualitatively whether it is more likely than not that a reporting
unit’s  carrying  amount  exceeds  its  fair  value,  referred  to  as  a  “step  zero”  approach.  Subsequently  (if  necessary,  after  step  zero),  if  the  carrying  value  of  a
reporting unit exceeded its fair value an impairment would be recorded. We would perform our goodwill impairment test by comparing the fair value of a
reporting unit with its carrying amount. The Company recorded an impairment of goodwill of $4,549 as a result of its annual impairment test on August 31,
2019. The Company considered the decline in its stock price as of September 30, 2019 to be a triggering event for an interim goodwill impairment test, which
resulted  in  an  additional  impairment  of  $1,743.  The  total  impairment  of  goodwill  recorded  during  the  year  ended  December  31,  2019  was  $6,292  and  is
included  in  impairment  charges  in  the  accompanying  consolidated  statements  of  operations  and  comprehensive  loss.  The  Company  consists  of  a  single
reporting unit and used its market capitalization to determine the fair value of the reporting unit. In order to determine the market capitalization, the Company
used the trailing 20-day volume weighted average price of its stock as of each testing date.

Accrued Clinical Expenses

When  preparing  our  financial  statements,  we  are  required  to  estimate  our  accrued  clinical  expenses.  This  process  involves  reviewing  contracts  and
communicating  with  our  personnel  to  identify  services  that  have  been  performed  on  our  behalf  and  estimating  the  level  of  service  performed  and  the
associated cost incurred for the service when we have not yet been invoiced or otherwise notified of actual cost. Payments under some of the contracts we
have  with  third  parties  depend  on  factors,  such  as  successful  enrollment  of  certain  numbers  of  patients,  site  initiation  and  the  completion  of  clinical  trial
milestones.

When accruing clinical expenses, we estimate the time period over which services will be performed and the level of effort to be expended in each
period. If possible, we obtain information regarding unbilled services directly from our service providers. However, we may be required to estimate the cost
of these services based only on information available to us. If we underestimate or overestimate the cost associated with a trial or service at a given point in
time,  adjustments  to  research  and  development  expenses  may  be  necessary  in  future  periods.  Historically,  our  estimated  accrued  clinical  expenses  have
approximated actual expense incurred.

Trends, Events and Uncertainties

As  with  other  companies  that  are  in  the  process  of  commercializing  novel  vaccines,  we  will  need  to  successfully  manage  normal  business  and
scientific risks. Research and development of new technologies is, by its nature, unpredictable. We cannot assure you that our technology will be adopted, that
we will ever earn revenues sufficient to support our operations, or that we will ever be profitable. Furthermore, other than as discussed in this report, we have
no committed source of financing and may not be able to raise money as and when we need it to continue our operations. If we cannot raise funds as and
when we need them, we may be required to severely curtail, or even to cease, our operations.

Other than as discussed above and elsewhere in this report, we are not aware of any trends, events or uncertainties that are likely to have a material

effect on our financial condition.

Related Parties

SciVac entered into a services agreement with OPKO Biologics Ltd. (“OPKO Bio”), a wholly-owned subsidiary of OPKO Health, Inc., a related
party shareholder of the Company, dated as of March 15, 2015 as amended on January 25, 2016, pursuant to which SciVac agreed to provide certain aseptic
process filling services to OPKO Bio. For the years ended December 31, 2019 and 2018 revenue recognized amounted to $0 and $0, respectively. Effective
October 17, 2018, OPKO Bio is no longer a related party.

During the year ended December 31, 2019, the Company entered into a car loan lease with an officer of the Company, as part of their compensation

arrangement, for $53, repayable over 3 years.

Our credit facility, pursuant to the Amended Credit Facility, as amended, with Perceptive Credit is from a lender that is affiliated with the Company’s

largest shareholder and is a related party, see Note 9 of Notes to Consolidated Financial Statements.

JOBS Act

In April 2012, the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”) was enacted in the United States Section 107 of the JOBS Act
provides that an “emerging growth company” can take advantage of the extended transition period provided in Section 7(a)(2)(B) of the Securities Act for
complying with new or revised accounting standards. Thus, an emerging growth company can delay the adoption of certain accounting standards until those
standards would otherwise apply to private companies. We have irrevocably elected not to avail ourselves of this extended transition period and, as a result,
we will adopt new or revised accounting standards on the relevant dates on which adoption of such standards is required for non-emerging growth public
companies.

ITEM 7A: QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Interest Rate Risk

We are exposed to market risk related to changes in interest rates with respect to our cash holdings and our outstanding long-term debt.

As of December 31, 2019, and 2018, we had cash of $44.2 million and $59.3 million, respectively, which has been deposited in high interest rate
bank accounts. Our cash holdings are in accordance with our investment policy approved by our board of directors, which specifies the categories, allocations
and ratings of securities we may consider for investment. The primary objective of our investment activities is to preserve principal while at the same time
maximizing  the  income  we  receive  without  significantly  increasing  risk.  We  do  not  hold  or  issue  derivatives,  derivative  commodity  instruments  or  other
financial instruments for speculative trading purposes. Further, we do not believe our cash has significant risk of default or illiquidity.

As of December 31, 2019 and 2018 we had long-term debt outstanding of $15.3 million and $15.3 million, respectively. The debt bears interest at the
greater of (a) one-month LIBOR (subject to a 5% cap) or (b) 1% plus the Applicable margin of 11%. The interest rate at December 31, 2019 and 2018 was
12.75% and 13.3125%, respectively. Our interest rate risk exposure is primarily due to LIBOR fluctuations when the rate is greater than 1%, capped to a
maximum of 5%.

Based on our current interest rate risk, we do not believe that our results of operations or our financial position would be materially affected by a

change in interest rates of 100 basis points.

Foreign Currency Risk

We are also exposed to market risk related to change in foreign currency exchange rates. We have operations in Israel, Canada, and the United States
and therefore we incur expenses in NIS, Canadian Dollars and United States dollars. We also contract with certain vendors that are located in Europe which
have  contracts  denominated  in  foreign  currencies.  We  are  subject  to  fluctuations  in  foreign  currency  rates  in  connection  with  our  foreign  operations  and
certain agreements. We do not currently hedge our foreign exchange rate risk. As of December 31, 2019, and December 31, 2018, we had minimal liabilities
denominated in foreign currencies.

ITEM 9A: CONTROLS AND PROCEDURES

Disclosure Controls and Procedures

Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed
by  an  issuer  in  the  reports  that  it  files  or  submits  under  the  Exchange  Act  is  accumulated  and  communicated  to  the  issuer’s  management,  including  its
principal  executive  and  principal  financial  officers,  or  persons  performing  similar  functions,  as  appropriate  to  allow  timely  decisions  regarding  required
disclosure.

We  carried  out  an  evaluation,  under  the  supervision  and  with  the  participation  of  our  management,  including  our  Chief  Executive  Officer  (our
principal  executive  officer)  and  our  Chief  Financial  Officer  and  Head  of  Business  Development  (our  principal  financial  and  accounting  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 Form 10-K. The evaluation was
undertaken  in  consultation  with  our  accounting  personnel  and  external  consultants.  Based  on  that  evaluation,  our  Chief  Executive  Officer  and  our  Chief
Financial Officer and Head of Business Development concluded that, as of December 31, 2019, our disclosure controls and procedures are effective to ensure
that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported
within the time periods specified in the SEC’s rules and forms.

Management’s Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining internal control over financial reporting. Internal control over financial reporting is
defined in Rule 13a-15(f) and 15d-15(f) promulgated under the Exchange Act as a process designed by, or under the supervision of, our principal executive
and  principal  financial  and  accounting  officers  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  financial  statements  for  external  purposes  in  accordance  with  generally  accepted
accounting principles and includes those policies and procedures that:

● pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of our assets;

● provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally
accepted accounting principles, and that our receipts and expenditures are being made only in accordance with authorizations of management and
our directors; and

● provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a

material effect on the financial statements.

Because  of  its  inherent  limitations,  our  internal  control  over  financial  reporting  may  not  prevent  or  detect  misstatements.  Therefore,  even  those
systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation. 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.

Our Chief Executive Officer and our Chief Financial Officer and Head of Business Development assessed the effectiveness of our internal control
over financial reporting as of December 31, 2019. In making this assessment, management evaluated the criteria set forth by the Committee of Sponsoring
Organizations of the Treadway Commission (COSO) in Internal Control—Integrated Framework (2013).

Based on our assessment, our Chief Executive Officer and our Chief Financial Officer and Head of Business Development determined that, as of

December 31, 2019, our internal control over financial reporting is effective.

Changes in Internal Control over Financial Reporting

There  have  been  no  changes  in  our  internal  control  over  financial  reporting  (as  such  term  is  defined  in  Rules  13a-15(f)  and  15d-15(f)  under  the
Exchange Act) during the fourth quarter of the last fiscal year that have materially affected, or are reasonably likely to materially affect, our internal control
over financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Stockholders of
VBI Vaccines Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of VBI Vaccines Inc. and Subsidiaries (the “Company”) as of December 31, 2019 and 2018,
and the related consolidated statements of operations and comprehensive loss, stockholders’ equity, and cash flows for each of the years then ended, and the
related  notes  (collectively  referred  to  as  the  “financial  statements”).  In  our  opinion,  the  financial  statements  present  fairly,  in  all  material  respects,  the
consolidated financial position of the Company as of December 31, 2019 and 2018, and the consolidated results of their operations and their cash flows for
each of the years then ended, 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  1  to  the
financial statements, the Company has incurred, and it anticipates it will continue to incur, significant losses and generate negative operating cash flows and
as such will require significant additional funds to continue its development activities to ultimately achieve commercial launch of its products. These factors
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  1.  The
financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Basis for Opinion

These  financial  statements  are  the  responsibility  of  the  Company’s  management.  Our  responsibility  is  to  express  an  opinion  on  the  Company’s  financial
statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”)
and are required to be independent with respect to the Company in accordance with the United States 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. The Company is not required to have, nor
were  we  engaged  to  perform,  an  audit  of  its  internal  control  over  financial  reporting.  As  part  of  our  audits  we  are  required  to  obtain  an  understanding  of
internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial
reporting. Accordingly, we express no such opinion.

Our  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.

We have served as the Company’s auditor since 2016.

Notes to Consolidated Financial Statements
(in thousands except share and per share amounts)

1. NATURE OF BUSINESS AND CONTINUATION OF BUSINESS

Corporate Overview

VBI Vaccines Inc. (the “Company” or “VBI”) was incorporated under the laws of British Columbia, Canada on April 9, 1965.

The Company and its wholly-owned subsidiaries, VBI Vaccines (Delaware) Inc., a Delaware corporation (“VBI DE”); VBI DE’s wholly-owned subsidiary,
Variation  Biotechnologies  (US),  Inc.,  a  Delaware  corporation  (“VBI  US”);  Variation  Biotechnologies,  Inc.  a  Canadian  company  and  the  wholly-owned
subsidiary of VBI US (“VBI Cda”); and SciVac Ltd. an Israeli company (“SciVac”) and SciVac Hong Kong Limited (“SciVac HK”) are collectively referred
to as the “Company”, “we”, “us”, “our” or “VBI”.

The Company’s registered office is located at Suite 1700, Park Place, 666 Burrard Street, Vancouver, BC V6C 2X8 with its principal office located at 222
Third  Street,  Suite  2241,  Cambridge,  MA  02142.  In  addition,  the  Company  has  manufacturing  facilities  located  in  Rehovot,  Israel  and  research  facilities
located in Ottawa, Ontario, Canada.

Principal Operations

VBI is a commercial-stage, biopharmaceutical company developing a next generation of vaccines to address unmet needs in infectious disease and immuno-
oncology. We are advancing the prevention and treatment of hepatitis B, with the only trivalent hepatitis B vaccine, Sci-B-Vac®, which is approved for use
and  commercially  available  in  Israel,  and  recently  completed  a  pivotal  Phase  III  program  in  the  United  States,  Europe,  and  Canada,  and  with  VBI-2601
(BRII-179),  an  immunotherapeutic  candidate  in  development  in  collaboration  with  Brii  Biosciences  Limited  (“Brii  Bio”)  for  a  functional  cure  for  chronic
hepatitis B. Our enveloped virus-like particle (“eVLP”) platform technology allows for the development of eVLP vaccines that closely mimic the target virus
to  elicit  a  potent  immune  response.  Integrating  our  cytomegalovirus  (“CMV”)  expertise  with  the  eVLP  platform  technology,  our  lead  eVLP  program
candidates include a glioblastoma (“GBM”) vaccine immunotherapeutic candidate, VBI-1901, and a prophylactic CMV vaccine candidate, VBI-1501. 

F-7

 
 
 
 
 
 
 
 
 
 
 
Liquidity and Going Concern

The Company has a limited operating history and faces a number of risks, including but not limited to, uncertainties regarding the success of the development
and commercialization of its products, demand and market acceptance of the Company’s products and reliance on major customers. The Company anticipates
that it will continue to incur significant operating costs and losses in connection with the development of its products.

The Company has an accumulated deficit of $262,388 as of December 31, 2019 and cash outflows from operating activities of $48,712, for the year-ended
December 31, 2019.

The Company will require significant additional funds to conduct clinical and non-clinical trials, achieve regulatory approvals, and, subject to such approvals,
commercially launch its products. The Company plans to finance future operations with existing cash reserves. Additional financing may be obtained from
the  issuance  of  equity  securities,  the  issuance  of  additional  debt,  structured  asset  financings,  and/or  revenues  from  potential  business  development
transactions, if any. There is no assurance the Company will manage to obtain these sources of financing, if required. The above conditions raise substantial
doubt about the Company’s ability to continue as a going concern. The consolidated financial statements do not include any adjustments to reflect the possible
future effects on the recoverability and classification of assets or the amounts and classifications of liabilities that may result should the Company be unable
to continue as a going concern.

On May 15, 2017, the Company entered into an equity distribution agreement (the “Distribution Agreement”) with a registered broker-dealer, as sales agent
(the “Sales Agent”), pursuant to which the Company may offer and sell, from time to time, through the Sales Agent its common shares having an aggregate
offering price of up to $30 million. The Company is not obligated to sell any common shares under the Distribution Agreement. Subject to the terms and
conditions  of  the  Distribution  Agreement,  the  Sales  Agent  will  use  commercially  reasonable  efforts  consistent  with  its  normal  trading  and  sales  practices,
applicable  state  and  federal  law,  rules  and  regulations,  and  the  rules  of  the  NASDAQ  Capital  Market  to  sell  shares  from  time  to  time  based  upon  the
Company’s instructions, including any price, time or size limits specified by the Company. The Company will pay the Sales Agent a commission of 3.0% of
the aggregate gross proceeds from each sale of common shares occurring pursuant to the Distribution Agreement, if any. The Distribution Agreement may be
terminated by the Sales Agent or the Company at any time upon ten days’ notice to the other party, or by the Sales Agent at any time in certain circumstances.
To-date, no amounts have been raised under the Distribution Agreement and there are no assurances as to how much, if any, funds will be raised under the
Distribution Agreement.

On December 4, 2018, the Company entered into a license and collaboration agreement (“License Agreement”) with Brii Bio, whereby we received a total
upfront payment of $11,000 to collaborate on the development of a hepatitis B recombinant protein based immunotherapeutic in China, Hong Kong, Taiwan
and  Macau  and  to  conduct  a  Phase  II  collaboration  clinical  trial.  In  connection  with  the  License  Agreement,  we  entered  into  a  stock  purchase  agreement
through which we issued to Brii Bio 2,295,082 common shares. See Note 11 and 12 for further discussion.

On  December  17,  2018,  the  Company  closed  an  underwritten  public  offering  of  30,665,304  common  shares  at  a  price  of  $1.40  per  share  for  total  gross
proceeds of $42,932. The Company incurred $3,152 of share issuance costs related to the offering resulting in net cash proceeds of $39,780.

In September 2019, the Company closed an underwritten public offering of 80,500,000 common shares at a price of $0.50 per share for total gross proceeds
of $40,250. The Company incurred $2,835 of share issuance costs related to the offering resulting in net cash proceeds of $37,415.

2. SIGNIFICANT ACCOUNTING POLICIES

Basis of Consolidation

The consolidated financial statements include the accounts of VBI and its wholly owned subsidiaries, SciVac, SciVac HK, VBI DE, VBI US and VBI Cda.

Intercompany balances and transactions between the Company and its subsidiaries are eliminated in the consolidated financial statements.

Foreign currency

The  functional  and  reporting  currency  of  the  Company  is  the  United  States  dollar.  Each  of  the  Company’s  subsidiaries  determines  its  own  respective
functional currency, based on the primary economic environment that it operates in, and this currency is used to separately measure each entity’s financial
position and operating results.

Assets and liabilities of foreign operations with a different functional currency from that of the Company are translated at the closing rate at the end of each
reporting period. Profit or loss items are translated at average exchange rates for all the relevant periods. All resulting translation differences are recognized as
a component of other comprehensive loss /income.

F-8

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Foreign exchange gains and losses arising from transactions denominated in a currency other than the functional currency of the entity involved, are included
in operating results.

Use of Estimates

Preparation  of  the  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 and disclosure of contingent assets
and  liabilities  at  the  date  of  the  consolidated  financial  statements  and  the  reported  amounts  of  revenues  and  expenses  during  the  reporting  period.  Actual
amounts  could  differ  from  the  estimates  made.  We  continually  evaluate  estimates  used  in  the  preparation  of  the  consolidated  financial  statements  for
reasonableness. Appropriate adjustments, if any, to the estimates used are made prospectively based upon such periodic evaluation. The significant areas of
estimation include revenue recognition, determining the deferred tax valuation allowance, estimating accrued clinical expenses, the inputs in determining the
fair value of the in-process research and development (“IPR&D”) and goodwill as part of the annual impairment analysis and the inputs in determining the
fair value of equity-based awards and warrants issued. Actual results may differ from those estimates.

Concentration of Credit Risk

Financial instruments that potentially subject us to significant concentrations of credit risk consist principally of cash and accounts receivable. We place our
cash primarily in commercial checking accounts. Commercial bank balances may from time to time exceed federal insurance limits. However, the Company
believes credit risk is low as the cash resides in large highly rated financial institutions.

The Company has not experienced any losses in cash and accounts receivable for years ended December 31, 2019 and 2018, respectively.

Inventory

Inventory components include all raw materials, work-in-progress and finished goods. Cost is determined on a first-in, first-out basis. The cost of inventories
comprises costs to purchase, costs incurred in bringing the inventories to their present location and condition, and costs incurred in the manufacturing process
including  labor  and  overhead.  Inventory  is  valued  at  the  lower  of  cost  or  net  realizable  value.  Net  realizable  value  is  the  estimated  selling  prices  in  the
ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. On an quarterly basis, the Company evaluates the
condition and age of inventories and makes provisions for slow moving inventories accordingly.

Deferred financing costs

Offering costs related to debt and equity financing consist of direct incremental external expenses. The Company presents debt issuance costs related to a
recognized long-term debt in the consolidated balance sheet as a direct reduction of the carrying value of the long-term debt, consistent with the accounting
treatment  of  debt  discounts.  The  amortization  of  debt  issuance  costs  follows  the  effective  interest  rate  method  (see  Note  9).  Offering  costs  related  to
registration statements and the initiation of the Distribution Agreement are recorded as an asset and are reclassified to equity upon the successful selling of
common shares. The costs are reviewed for impairment and will be recorded to expense if and when the Company determines that future equity offerings are
not probable of occurring. At December 31, 2019 and 2018, the Company had $169 and $154 of deferred offering costs, respectively, recorded as an other
current asset.

Property and equipment

Property and equipment are recorded at cost less accumulated depreciation.

F-9

 
 
 
 
 
 
 
 
 
 
 
 
 
 
The assets are depreciated by the straight-line method over the estimated useful lives of the related assets as follows:

Furniture and office equipment
Machinery and equipment
Computers
Leasehold improvements

Number of years
5-14
3-7
2-3
shorter of useful life or the term of the lease

When assets are retired or otherwise disposed of, the cost and the related accumulated depreciation is removed from the accounts, and any resulting gain or
loss is recognized in the consolidated statement of operations and comprehensive loss. The cost of maintenance and repairs is charged to expense as incurred;
significant renewals and betterments are capitalized.

Impairment of long-lived assets

Long-lived  assets,  such  as  property  and  equipment  and  finite-lived  intangible  assets,  are  reviewed  for  impairment  whenever  events  or  changes  in
circumstances indicate that the carrying amount of the asset may not be recoverable. Recoverability of assets to be held and used is measured by comparison
of the carrying amount of an asset to the estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of the asset
exceeds its estimated future cash flows, then an impairment charge is recognized for the amount by which the carrying amount of the asset exceeds the fair
value of the asset.

The  Company  recorded  an  impairment  of  $278  during  the  year  ended  December  31,  2018  related  to  certain  leasehold  improvements  and  manufacturing
equipment  no  longer  being  utilized  in  the  business  as  a  result  of  the  modernization  and  capacity  increase  of  our  manufacturing  facility.  The  amount
represented the remaining net book value of these assets. The impairment is included in impairment charges in the accompanying consolidated statements of
operations and comprehensive loss. The Company did not record an impairment for long-lived assets during the year ended December 31, 2019.

In-Process Research and Development Assets and Goodwill

The  Company’s  intangible  assets  determined  to  have  indefinite  useful  lives  including  IPR&D  and  goodwill,  are  tested  for  impairment  annually,  or  more
frequently  if  events  or  circumstances  indicate  that  the  assets  might  be  impaired.  Such  circumstances  could  include  but  are  not  limited  to:  (i)  a  significant
adverse change in legal factors or in business climate, (ii) unanticipated competition, or (iii) an adverse action or assessment by a regulator. The Company has
established August 31st as the date for its annual impairment test of IPR&D and goodwill.

The IPR&D assets, which consist of CMV and GBM projects, were acquired in a business combination, capitalized as an intangible asset and are tested for
impairment at least annually until commercialization, after which time the IPR&D is amortized over its estimated useful life. The impairment test compares
the carrying amount of the IPR&D asset to its fair value. If the carrying amount exceeds the fair value of the asset, such excess is recorded as an impairment
loss.  There  was  no  IPR&D  impairment  determined  as  a  result  of  the  Company’s  annual  testing  on  August  31,  2019.  The  fair  value  of  the  IPR&D  assets
included in the impairment test was determined using the income approach method and is considered Level 3 in the fair value hierarchy. Some of the more
significant estimates and assumptions inherent in the estimate of the fair value of IPR&D assets include the amount and timing of costs to develop the IPR&D
into viable products, the amount and timing of future cash inflows, the discount rate and the probability of technical and regulatory success applied to the cash
flows. The discount rate used was 12.5% and the cumulative probability of technical and regulatory success to achieve approval to market the products ranged
from approximately 6% to 17%.

Goodwill  represents  the  excess  of  the  purchase  price  over  the  fair  value  of  the  net  tangible  and  identifiable  intangible  assets  acquired  in  a  business
combination. When evaluating goodwill for impairment, we may first perform an assessment qualitatively whether it is more likely than not that a reporting
unit’s  carrying  amount  exceeds  its  fair  value,  referred  to  as  a  “step  zero”  approach.  Subsequently  (if  necessary  after  step  zero),  if  the  carrying  value  of  a
reporting unit exceeded its fair value an impairment would be recorded. We would perform our goodwill impairment test by comparing the fair value of a
reporting unit with its carrying amount. The Company recorded an impairment of goodwill of $4,549 as a result of its annual impairment test on August 31,
2019. The Company considered the decline in its stock price as of September 30, 2019 to be a triggering event for an interim goodwill impairment test, which
resulted  in  an  additional  impairment  of  $1,743.  The  total  impairment  of  goodwill  recorded  during  the  year  ended  December  31,  2019  was  $6,292  and  is
included  in  impairment  charges  in  the  accompanying  consolidated  statements  of  operations  and  comprehensive  loss.  The  Company  consists  of  a  single
reporting unit and used its market capitalization to determine the fair value of the reporting unit. In order to determine the market capitalization, the Company
used the trailing 20-day volume weighted average price of its stock as of each testing date.

F-10

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Other Intangible Assets

The Company’s other intangible assets include patents with finite lives. These assets obtained are recorded at cost less accumulated amortization and any
impairment losses.

The Company amortizes intangible assets with finite lives on a straight-line basis over their estimated useful lives.

Long Term Debt

The Company accounts for amendments to long-term debt as a substantial modification if the present value of the cash flows under the terms of the new debt
instrument  is  at  least  10  percent  different  from  the  present  value  of  the  remaining  cash  flows  under  the  terms  of  the  original  instrument.  A  substantial
modification  shall  be  accounted  for  like  an  extinguishment.  If  the  cash  flow  effect  on  a  present  value  basis  is  less  than  10%,  the  debt  instruments  are
accounted for as a debt modification.

Research and development

All costs of research and development are expensed as incurred.

When  preparing  our  financial  statements,  we  are  required  to  estimate  our  accrued  clinical  expenses.  This  process  involves  reviewing  contracts  and
communicating  with  our  personnel  to  identify  services  that  have  been  performed  on  our  behalf  and  estimating  the  level  of  service  performed  and  the
associated cost incurred for the service when we have not yet been invoiced or otherwise notified of actual cost. Payments under some of the contracts we
have  with  third  parties  depend  on  factors,  such  as  successful  enrollment  of  certain  numbers  of  patients,  site  initiation  and  the  completion  of  clinical  trial
milestones.

When accruing clinical expenses, we estimate the time period over which services will be performed and the level of effort to be expended in each period. If
possible, we obtain information regarding unbilled services directly from our service providers. However, we may be required to estimate the cost of these
services based only on information available to us. If we underestimate or overestimate the cost associated with a trial or service at a given point in time,
adjustments  to  research  and  development  expenses  may  be  necessary  in  future  periods.  Historically,  our  estimated  accrued  clinical  expenses  have
approximated actual expense incurred.

Revenue recognition

We  recognize  revenue  when  we  transfer  promised  goods  or  services  to  customers  in  an  amount  that  reflects  the  consideration  to  which  we  expect  to  be
entitled  in  exchange  for  those  goods  or  services.  To  determine  revenue  recognition  for  contracts  with  customers  we  perform  the  following  five  steps:  (i)
identify  the  contract(s)  with  a  customer;  (ii)  identify  the  performance  obligation(s)  in  the  contract;  (iii)  determine  the  transaction  price;  (iv)  allocate  the
transaction price to the performance obligation(s) in the contract; and (v) recognize revenue when (or as) we satisfy the performance obligation(s). At contract
inception, we assess the goods or services promised within each contract, assess whether each promised good or service is distinct and identify those that are
performance obligations.

The Company must use significant judgment to determine: a) the number of performance obligations based on the determination under step (ii) above and
whether those performance obligations are distinct from other performance obligations in the contract; b) the transaction price under step (iii) above; and c)
the stand-alone selling price for each performance obligation identified in the contract for the allocation of transaction price in step (iv) above. The Company
uses  judgment  to  determine  whether  milestones  or  other  variable  consideration,  except  for  royalties,  should  be  included  in  the  transaction  price.  The
transaction price is allocated to each performance obligation on an estimated stand-alone selling price basis, for which the Company recognizes revenue as or
when the performance obligations under the contract are satisfied.

F-11

 
 
 
 
 
 
 
 
 
 
 
 
 
 
Where  a  portion  of  non-refundable  up-front  fees  or  other  payments  received  are  allocated  to  continuing  performance  obligations  under  the  terms  of  a
collaborative arrangement, they are recorded as contract liabilities and recognized as revenue when (or as) the underlying performance obligation is satisfied.

Product sales

The Company recognizes revenue from product sales when obligations under the terms of the contract with the customer are satisfied; this occurs upon the
transfer of control of the goods to the customers.

Collaborative Arrangements

The  Company  first  evaluates  license  and/or  collaboration  arrangements  to  determine  whether  the  arrangement  (or  part  of  the  arrangement)  represents  a
collaborative arrangement pursuant to Accounting Standards Codification (“ASC”) Topic 808, Collaborative Arrangements (“ASC 808”), based on the risks
and rewards and activities of the parties pursuant to the contractual arrangement. The Company then determines if the collaborative arrangements are within
the scope of ASC Topic 606, Revenue Recognition (“ASC 606”).

Collaborative arrangements with partners which are within the scope of ASC 606 typically include payment to us of one or more of the following: (i) license
fees;  (ii)  research  and  development  services  to  be  performed  as  part  of  the  contract  (“R&D  services”)  (iii)  payments  related  to  the  achievement  of
developmental, regulatory, or commercial milestones; and (iv) royalties on net sales of licensed products.

Collaborative  arrangements  (or  elements  within  the  contract  that  are  deemed  part  of  a  collaborative  arrangement)  with  partners  which  represent  a
collaborative relationship and not a customer relationship, are accounted for outside the scope of ASC Topic 606.

License fees

If  a  license  to  our  intellectual  property  is  determined  to  be  distinct  from  the  other  performance  obligations  identified  in  the  arrangement,  we  recognize
revenues from non-refundable, up-front fees allocated to the license when the license is transferred to the licensee and the licensee is able to use and benefit
from the license.

R&D Services

The  promises  under  the  Company’s  collaboration  and  license  agreements  generally  include  research  and  development  services  to  be  performed  by  the
Company.  For  performance  obligations  that  include  research  and  development  services,  the  Company  generally  recognizes  revenue  allocated  to  such
performance obligations based on an appropriate measure of progress. The Company utilizes judgment to determine the appropriate method of measuring
progress for purposes of recognizing revenue, which is generally an input measure such as costs incurred. The Company evaluates the measure of progress
each reporting period and, if necessary, adjusts the measure of performance and related revenue recognition.

Royalties

For arrangements that include sales-based royalties, including milestone payments based on a level of sales, and the license is deemed to be the predominant
item to which the royalties relate, the Company recognizes revenue at the later of (i) when the related sales occur or (ii) when the performance obligation to
which some or all of the royalty has been allocated has been satisfied (or partially satisfied). To date, the Company has not recognized any royalty revenue
resulting from any of its licensing arrangements.

Employee benefits

The Company operates a defined contribution retirement benefit plan for all qualifying employees with corresponding federal, and state/provincial law. For
qualifying employees in Israel, under Israeli law, the assets of the plan are held separately from those of the Company in funds under the control of trustees.

The Company’s liability for severance pay for the employees of its subsidiary in Israel is calculated in accordance with Israeli law based on the most recent
salary paid to employees and the length of employment in the Company. The Company records its obligation with respect to employee severance payments as
if it were payable at each balance sheet date.

Obligations for employee benefits are recognized as a component of operating expenses in the statement of operations and comprehensive loss in the periods
during which services are rendered by employees. The Company records its obligation with respect to employee severance payments as if it was payable at
each balance sheet date.

Income taxes

Deferred tax assets and liabilities are determined based on the differences between the financial reporting and tax basis of assets and liabilities using enacted
tax rates which will be in effect when the differences reverse. The Company provides a valuation allowance against net deferred tax assets unless, based upon
the available evidence, it is more likely than not that the deferred tax asset will be realized.

The Company recognizes 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 the taxing authorities based on the technical merits of the position. The benefit is measured as the largest amount that is more likely than not to be realized
upon ultimate settlement. The Company does not have any uncertain tax positions or accrued penalties and interest as of December 31, 2019 and 2018. If
such matters were to arise, the Company would recognize interest and penalties related to income tax matters in income tax expense.

The Company’s claim for Scientific Research and Experimental Development (SR&ED) deductions for income tax purposes are based upon management’s
interpretation  of  the  applicable  legislation  in  the  Income  Tax  Act  (Canada).  These  amounts  are  subject  to  review  and  acceptance  by  the  Canada  Revenue
Agency and may be subject to adjustment.

Fair value measurements of financial instruments

Accounting  guidance  defines  fair  value  as  the  price  that  would  be  received  to  sell  an  asset  or  paid  to  transfer  a  liability  (the  exit  price)  in  an  orderly
transaction between market participants at the measurement date. The accounting guidance outlines a valuation framework and creates a fair value hierarchy
in order to increase the consistency and comparability of fair value measurements and the related disclosures.

The fair value hierarchy is broken down into three levels based on the source of inputs as follows:

Level 1 — Valuations based on unadjusted quoted prices in active markets for identical assets or liabilities.

Level 2 — Valuations based on observable inputs and quoted prices in active markets for similar assets and liabilities.

Level 3 — Valuations based on inputs that are unobservable and models that are significant to the overall fair value measurement.

Financial  instruments  recognized  in  the  consolidated  balance  sheet  consist  of  cash,  accounts  receivable,  other  current  assets,  accounts  payable  and  other
current liabilities. The Company believes that the carrying value of its current financial instruments approximates their fair values due to the short-term nature
of these instruments. The Company does not hold any derivative financial instruments.

The carrying amounts of the Company’s long-term financial assets approximate their respective fair values.

The fair value of our outstanding debt, including the current portion, is estimated to be approximately $15,272 and $14,975 at December 31, 2019 and 2018,
respectively. The fair value of the outstanding debt is considered to be Level 3 in the fair value hierarchy and was estimated by discounting to present value
the scheduled coupon payments and principal repayment, using an appropriate fair market yield.

Loss per share

Basic  loss  per  share  is  computed  by  dividing  net  loss  by  the  weighted  average  number  of  shares  outstanding  during  the  period.  Diluted  loss  per  share  is
computed  by  dividing  net  loss  by  the  weighted  average  number  of  shares  outstanding  after  giving  effect  to  the  impact  of  all  potentially  dilutive  potential
shares. There was no dilutive effect on the earnings per share for all periods presented.

Leases

The  Company  determines  if  an  arrangement  is  a  lease  at  inception.  For  the  Company’s  operating  leases,  the  right-of-use  (“ROU”)  assets  represents  the
Company’s right to use an underlying asset for the lease term and operating lease liabilities represent an obligation to make lease payments arising from the
lease. ROU assets and lease liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. Since
the Company’s lease agreements do not provide an implicit rate, the Company estimated an incremental borrowing rate in determining the present value of its
lease  payments.  Operating  lease  expense  is  recognized  on  a  straight-line  basis  over  the  lease  term,  subject  to  any  changes  in  the  lease  or  expectations
regarding the terms. Variable lease costs such as operating costs and property taxes are expensed as incurred. See also Note 3.

Stock-based compensation

The  Company  accounts  for  share-based  awards  to  employees  and  directors  in  accordance  with  the  provisions  of  ASC  718,  Compensation—Stock
Compensation  (“ASC  718”).  Under  ASC  718,  share-based  awards  are  valued  at  fair  value  on  the  date  of  grant  and  that  fair  value  is  recognized  over  the
requisite service period. The Company values its stock options using the Black-Scholes option pricing model. The Company accounts for forfeitures when
they occur.

The  Company  accounts  for  share-based  payments  to  non-employees  issued  in  exchange  for  services  based  upon  the  fair  value  of  the  equity  instruments
issued. Compensation expense for stock options issued to non-employees is calculated using the Black-Scholes option pricing model and is recorded over the
service  performance  period.  Options  subject  to  vesting  are  required  to  be  periodically  remeasured  over  their  service  performance  period  until  the
measurement date, when service is completed.

3. NEW ACCOUNTING PRONOUNCEMENTS

Recently Adopted Accounting Pronouncements

Leases

In  February  2016,  the  Financial  Accounting  Standards  Board  (“FASB”)  issued  Accounting  Standards  Update  (“ASU”)  No.  2016-02,  Leases  (Topic  842)
(“ASU  2016-02”),  which  sets  out  the  principles  for  the  recognition,  measurement,  presentation  and  disclosure  of  leases  for  both  lessees  and  lessors.  On
January 1, 2019, the Company adopted the new lease standard using the optional transition method under which comparative financial information will not be
restated and continue to apply the provisions of the previous lease standard in its annual disclosures for the comparative periods. In addition, the new lease
standard provides a number of optional practical expedients in transition. The Company elected the package of practical expedients. As such, the Company
did not have to reassess whether expired or existing contracts are or contain a lease and did not have to reassess the lease classifications or reassess the initial
direct costs associated with expired or existing leases.

The  new  lease  standard  also  provides  practical  expedients  for  an  entity’s  ongoing  accounting.  The  Company  elected  the  short-term  lease  recognition
exemption under which the Company will not recognize ROU assets or lease liabilities for short term leases. The Company elected the practical expedient to
not separate lease and non-lease components.

On January 1, 2019, the Company recognized ROU assets and lease liabilities of $1,653 on its consolidated balance sheet.

Compensation – Stock Compensation

In  June  2018,  the  FASB  issued  ASU  2018-07:  Compensation  –  Stock  Compensation  (Topic  718):  Improvements  to  Nonemployee  Share-Based  Payment
Accounting. This ASU expands the scope of Topic 718 to include share-based payment transactions for acquiring goods and services from non-employees,
and as a result, the accounting for share-based payments to non-employees will be substantially aligned. Our adoption of this ASU, effective January 1, 2019,
did not have a material impact on our consolidated financial statements and the related footnote disclosures.

Recently Issued Accounting Standards, Not Yet Adopted

Intangibles – Goodwill and Other, Internal-Use Software

In August 2018, the FASB issued ASU 2018-15: Intangibles – Goodwill and Other – Internal-Use Software (Subtopic 350-40): Customers’ accounting for
implementation  costs  incurred  in  a  cloud  computing  arrangement  that  is  a  service  contract  (“ASU  2018-15”).  ASU  2018-15  aligns  the  requirements  for
capitalizing  implementation  costs  incurred  in  a  hosting  arrangement  that  is  a  service  contract  with  the  requirements  for  capitalizing  implementation  costs
incurred  to  develop  or  obtain  internal-use  software. Accordingly,  the  amendments  require  an  entity  (customer)  in  a  hosting  arrangement  that  is  a  service
contract to follow the guidance in Subtopic 350-40 to determine which implementation costs to capitalize as an asset related to the service contract and which
costs to expense. ASU 2018-15 is effective for fiscal years beginning after December 15, 2019 and interim periods within those fiscal years. Early adoption is
permitted. This ASU can be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption. The Company will
apply this ASU prospectively and we do not anticipate that this new guidance will have a material impact on its consolidated financial statements and related
disclosures going forward.

The  license  is  held  in  Israel  at  SciVac.  Amortization  expenses  for  the  years  ended  December  31,  2019  and  2018  amounted  to  $62  and  $61,  respectively.
Amortization is expected to be approximately $63 per year until its fully amortized. These amounts do not include any amortization related to the IPR&D
assets, which will not begin amortizing until the Company commercializes its products.

The IPR&D assets are in VBI Cda and the change in carrying value from December 31, 2018 relates to currency translation adjustments which increased
IPR&D assets by $2,552 for the year ended December 31, 2019. The change in carrying value from December 31, 2017 to December 31, 2018 relates to
currency translation adjustments which decreased IPR&D assets by $4,976.

8. LOSS PER SHARE OF COMMON SHARES

Basic  loss  per  share  is  computed  by  dividing  net  loss  applicable  to  common  stockholders  by  the  weighted  average  number  of  shares  of  common  shares
outstanding during each period. Diluted loss per share includes the effect, if any, from the potential exercise or conversion of securities, such as warrants, and
stock  options,  which  would  result  in  the  issuance  of  incremental  shares  of  common  shares  unless  such  effect  is  anti-dilutive.  In  computing  the  basic  and
diluted net loss per share applicable to common stockholders, the weighted average number of shares remained the same for both calculations due to the fact
that  when  a  net  loss  exists,  dilutive  shares  are  not  included  in  the  calculation.  These  potentially  dilutive  securities  are  more  fully  described  in  Note  11,
Stockholders’ Equity and Additional Paid-in Capital.

On  May  6,  2016,  the  Company  through  VBI  US  assumed  a  term  loan  facility  with  Perceptive  Credit  Holdings,  LP,  a  related  party  (the  “Lender”)  in  the
amount  of  $6,000  (the  “Facility”).  On  December  6,  2016,  the  Company  amended  the  Facility  (the  “Amended  Credit  Facility”)  and  raised  the  Lender’s
commitment  amount  to  $13,200,  which  was  combined  with  the  remaining  balance  from  the  Facility  of  $1,800.  In  connection  with  the  Amended  Credit
Facility, on December 6, 2016 the Company issued to the Lender two warrants; the first warrant to purchase 363,771 shares of the Company’s common shares
at an exercise price of $4.13, and the second warrant to purchase 1,341,282 shares of the Company’s common shares at an exercise price of $3.355. The total
proceeds attributed to the warrants was $2,793 based on the relative fair value of the warrants as compared to the sum of the fair values of the warrants and
debt. This resulted in the debt being issued at a discount. The Company incurred $360 of debt issuance costs and is required to pay an exit fee of $300 upon
full repayment of the debt resulting in additional debt discount. Following the Amended Credit Facility and the warrant issuance, the total debt discount was
$3,453.

On July 17, 2018, the Company amended the Amended Credit Facility (the “Second Amendment”) to extend the period the Company is required to pay only
the interest on the loan from May 31, 2018 to December 31, 2018 and to extend the expiration date of certain warrants to purchase 363,771 common shares
issued to the Lender with an original expiration date of July 25, 2019 to December 6, 2021. The Company accounted for this as a debt modification, and as a
result  of  the  extension  of  the  warrant  expiration  date  in  connection  with  the  Second  Amendment,  the  debt  discount  was  increased  by  $386.  This  amount
represents the incremental fair value of the modified warrants. 

On January 31, 2019, the Company further amended the Amended Credit Facility (the “Third Amendment”) to i) extend the period the Company is required
to pay only the interest on the loan from December 31, 2018 to January 31, 2020, ii) extend the maturity of the term loan to June 30, 2020 and iii) reduce the
exercise price of certain warrants to purchase common shares issued to the Lender to $2.75 from $4.13 for 363,771 warrants issued on July 25, 2014 and for
363,771 warrants issued on December 6, 2016 and from $3.355 for 1,341,282 warrants issued on December 6, 2016. The Company has accounted for this as a
debt modification, and as a result of the amendment to the exercise price in connection with the Third Amendment, the debt discount was increased by $179.
This amount represents the incremental fair value of the modified warrants.

The total principal amount of the loan under the Amended Credit Facility, as subsequently amended, outstanding at December 31, 2019, including the $300
exit fee discussed below, is $15,300. The principal amount of the loan made under the Amended Credit Facility accrues interest at an annual rate equal to the
greater of (a) one-month LIBOR (subject to a 5.00% cap) or (b) 1.00%, plus the applicable margin. The applicable margin will be 11.00%. The Company was
required to only pay interest initially until May 31, 2018, which date was extended to December 31, 2018, pursuant to the Second Amendment and further
extended to January 31, 2020, pursuant to the Third Amendment. The interest rate as of December 31, 2019 was 12.75%. Upon the occurrence of an Event of
Default  (as  defined  in  the  Amended  Credit  Facility),  and  during  the  continuance  of  an  Event  of  Default,  the  applicable  margin,  described  above,  will  be
increased by 4.00% per annum. This term loan facility maturity date has been extended from December 6, 2019 to June 30, 2020 and includes both financial
and  non-financial  covenants,  including  a  minimum  cash  balance  requirement.  The  Company  was  in  compliance  with  these  covenants  as  of  December  31,
2019. Pursuant to the Amended Credit Facility, the Company agreed that the Lender shall designate an individual who would be appointed to the Company’s
board  of  directors  (the  “Board”).  The  Lender’s  designee  was  also  a  portfolio  manager  of  the  Company’s  largest  shareholder.  Effective  January  2018,  the
Lender’s designee resigned from our Board.

The Company’s obligations under the Amended Credit Facility are secured on a senior basis by a lien on substantially all of the assets of the Company and its
subsidiaries and are guaranteed by the Company and its subsidiaries. The Amended Credit Facility also contains customary events of default.

The total debt discount of $4,018 is being charged to interest expense using the effective interest method over the term of the debt. As of December 31, 2019,
and December 31, 2018, the unamortized debt discount was $455 and $1,274, respectively.

Defined contribution plan

The  Company  operates  a  defined  contribution  retirement  benefit  plan  for  all  qualifying  employees  in  accordance  with  corresponding  federal  and
state/provincial law. For qualifying employees in Israel, under Israeli law, the assets of the plan are held separately from those of the Company, in funds under
the control of trustees.

The total expense recognized for the years ended December 31, 2019 and 2018 was $263 and $218, respectively, and represents contributions payable to these
plans by the Company at rates specified in the rules of the plan.

For VBI DE and VBI Cda employees, the respective companies contribute up to 1.5% of the employee’s salary to a retirement benefit, which contribution is
based on a 25% match of participating employee contributions. Such expense is not significant for any of the periods presented.

Liability for severance pay

Israel’s labor laws and the Law “severance pay, 1963” (the “Law”), require the Company to pay severance pay to employees during dismissal, disability and
retirement. Legal retirement age under Israeli labor laws is currently 64 for women and 67 for men. Thus, under the plan, an employee who was employed by
the Company for at least one year (and in the circumstances defined by the law) and was involuntarily terminated by the Company after the said period is
entitled to severance pay. The rate of compensation listed in the Law is the employee’s final monthly salary for each year of employment.

F-21

 
 
 
 
 
 
 
 
 
Under the program, the Company is obligated to deposit amounts at the rate fixed by Law (since January 1, 2008), to ensure the accrual of such a severance
pay  due  to  the  employee  as  described  above.  The  rate  required  by  law  is  8.33%  of  the  employee’s  salary,  which  is  deposited  in  a  pension  fund/insurance
severance fund.

Included in cost of revenues for the year ended December 31, 2019 is $24 of severance payments pursuant to the aforementioned statutory or contractual
obligations.

Included in research and development expenses for the year ended December 31, 2018 is $24 of severance payments pursuant to the aforementioned statutory
or contractual obligations.

Stock option plans

The Company’s stock option plans are approved by and administered by the Board and its Compensation Committee. The Board designates, in connection
with recommendations from the Compensation Committee, eligible participants to be included under the plan, and designates the number of options, exercise
price and vesting period of the new options.

2006 VBI US Stock Option Plan

The  2006  VBI  US  Stock  Option  Plan  (the  “2006  Plan”),  was  approved  by  and  was  previously  administered  by  the  VBI  US  board  of  directors  which
designated  eligible  participants  to  be  included  under  the  2006  Plan,  and  designated  the  number  of  options,  exercise  price  and  vesting  period  of  the  new
options. The 2006 Plan was not approved by the stockholders of VBI US. The 2006 Plan was superseded by the 2014 Plan (as defined below) following the
PLCC Merger and no further options will be issued under the 2006 Plan. As of December 31, 2019, there were 994,716 options outstanding under the 2006
Plan.

2013 Stock Incentive Plan

The 2013 Equity Incentive Plan (the “2013 Plan”) was approved by and was previously administered by the VBI DE board of directors which designated
eligible participants to be included under the 2013 Plan, and designated the number of options, exercise price and vesting period of the new options. The 2013
Plan was approved by the VBI DE shareholders on November 8, 2013. No further options will be issued under the 2013 Plan. As of December 31, 2019, there

outstanding under the 2014 Plan.

2016 VBI Equity Incentive Plan

The  2016  Plan  is  a  rolling  incentive  plan  that  sets  the  number  of  common  shares  issuable  under  the  2016  Plan,  together  with  any  other  security-based
compensation arrangement of the Company, at a maximum of 10% of the aggregate common shares issued and outstanding on a non-diluted basis at the time
of any grant under the 2016 Plan. The 2016 Plan is an omnibus equity incentive plan pursuant to which the Company may grant equity and equity-linked
awards to eligible participants in order to promote the success of the Company by providing a means to offer incentives and to attract, motivate, retain and
reward  persons  eligible  to  participate  in  the  2016  Plan.  Grants  under  the  2016  Plan  include  a  grant  or  right  consisting  of  one  or  more  options,  stock
appreciation rights (“SARs”), restricted share units (“RSUs”), performance share units (“PSUs”), shares of restricted stock or other such award as may be
permitted under the 2016 Plan. As of December 31, 2019, there were 4,955,750 options outstanding and 157,997 RSUs unvested under the 2016 Plan.

The principal features of the 2016 Plan are as follows:

Eligible Participants

Eligible participants include individuals employed (including services as a director) by the Company or its affiliates, including a service provider, who, by the
nature of his or her position or job is, in the opinion of the Board, in a position to contribute to the success of the Company (“Eligible Persons”).

F-23

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Reservation of Shares

The  aggregate  number  of  common  Shares  reserved  for  issuance  to  any  one  participant  under  the  2016  Plan,  together  with  all  other  security-based
compensation arrangements must not exceed 5% of the total number of issued and outstanding common shares on a non-diluted basis.

The maximum number of common shares (a) issued to insiders within any one year period; and (b) issuable to insiders at any time, under the 2016 Plan, when
combined with all of the Company’s other security-based compensation arrangements, must not exceed 10% of the total number of issued and outstanding
common shares.

The aggregate number of common shares remaining available for issuance for awards under the 2016 Plan totaled 10,001,505 at December 31, 2019.

The source of common shares issued under the various stock option plans are new common shares.

Options and Stock Appreciation Rights

The Company may grant options to Eligible Persons on such terms and conditions consistent with the 2016 Plan. The exercise price for an option must not be
less than 100% of the “market price,” as that term is defined in the 2016 Plan, based on the trading price per common share, on the date of grant of such
option.

With  respect  to  SARs  attached  to  an  option,  which  allows  the  holder,  upon  vesting  of  the  option  and  Tandem  SAR,  to  choose  to  exercise  the  stock
appreciation right or to exercise the option, the exercise price is the exercise price applicable to the option (as explained above) to which the Tandem SAR
relates, subject to adjustment provisions under the 2016 Plan. For stand-alone SARs, a SAR that is granted without reference to any related Company options,
the base price must not be less than 100% of the market price on the date of grant of such Stand-Alone SAR. Stock appreciation rights (and in the case of
Tandem  SARs,  the  related  options)  will  be  settled  by  payment  in  cash  or  common  shares  or  a  combination  thereof,  with  an  aggregate  value  equal  to  the
product  of  (a)  the  excess  of  the  market  price  on  the  date  of  exercise  over  the  exercise  price  or  base  price  under  the  applicable  stock  appreciation  right,
multiplied by (b) the number of stock appreciation rights exercised or settled. The Company has not issued any SARs under the 2016 Plan at December 31,
2019 and 2018.

Under the 2016 Plan unless otherwise designated by the Board of Directors, 25% of the options will vest on each of the first four anniversaries of the grant
date. The term of options will be for a maximum of 10 years, unless exercised or terminated earlier in accordance with the terms of the 2016 VBI Plan or the
applicable grant agreement.

Upon a participant’s termination of employment due to death, or in the case of disability: (a) the outstanding options that were granted prior to the year that
includes the participant’s death or disability that have not become vested prior to such date will continue to vest and, upon vesting, be exercisable during the
36-month period following such date; and (b) the outstanding options that have become vested prior to the participant’s death or disability will continue to be
exercisable during the 36-month period following such date.

In the case of a participant’s termination of employment or contract for services without cause: (a) the outstanding options that have not become vested prior
to the participant’s termination will continue to vest and, upon vesting, be exercisable during the 120-day period following such date; and (b) the outstanding
options that have become vested prior to the participant’s termination will continue to be exercisable during the 120-day period following such date.

In the case of a participant’s termination due to resignation (including voluntary withdrawal of services by a non-employee participant): (a) the outstanding
options that have not become vested prior to the date of notice of resignation will be forfeited and cancelled as of such date; and (b) the outstanding options
that have become vested prior to the date of notice of resignation will continue to be exercisable during the 90-day period following such date.

In  the  case  of  a  participant’s  termination  of  employment  or  contract  for  services  for  cause,  any  and  all  then  outstanding  unvested  options  granted  to  such
participant will be immediately forfeited and cancelled, without any consideration therefor, as of the date such notice of termination is given.

Share Units

The Board of Directors may grant share units, which include RSUs and PSUs, to Eligible Persons on such terms and conditions consistent with the 2016 Plan.

The Board will determine the grant value and the valuation date for each grant of share units. The number of share units to be covered by each grant will be
determined by dividing the grant value for such grant by the market value of a common share as of the valuation date, rounded up to the next whole number.

Share units subject to a grant will vest as specified in the grant agreement governing such grant, provided that the participant is employed on the relevant
vesting  date.  RSUs  and  PSUs  will  be  settled  upon,  or  as  soon  as  reasonably  practicable  following  the  vesting  thereof,  subject  to  the  terms  of  the  grant
agreement. In all events, RSUs and PSUs will be settled on or before the earlier of the 90th day following the vesting date and the date that is 2 ½ months
after  the  end  of  the  year  in  which  the  vesting  occurred.  Settlement  will  be  made  by  way  of  issuance  of  one  common  share  for  each  RSU  or  PSU,  a  cash
payment equal to the market value of the RSUs or PSUs being settled, or a combination thereof. If the share units would be settled within a blackout period,
such  settlement  will  be  postponed  until  the  earlier  of  the  6th  trading  day  following  the  end  of  such  blackout  period  and  the  otherwise  applicable  date  of
settlement as determined in accordance with the settlement provision set out above. The Company has not issued any PSUs under this plan at December 31,
2019 and 2018. All RSUs issued under the plan at December 31, 2019 and 2018 contain no cash settlement provision.

If and when cash dividends are paid with respect to common shares to shareholders of record during the period from the grant date to the date of settlement of
the RSUs or PSUs, a number of dividend equivalent RSUs or PSUs, as applicable, will be credited to the share unit account of such participant.

In the event a participant’s employment is terminated due to resignation, share units that have not vested prior to the date of resignation will not vest and all
such common shares will be forfeited immediately.

In the case of a participant’s termination due to death, or in the case of disability, all share units granted prior to the year that includes the participant’s death
or disability, that have not vested prior to the participant’s death or disability will vest at the end of the vesting period and in the case of PSUs, subject to the
achievement  of  applicable  performance  conditions  and  the  adjustment  of  the  number  of  PSUs  that  vest  to  reflect  the  extent  to  which  such  performance
conditions were achieved.

In the event a participant’s employment or contract for services is terminated without cause, prior to the end of a vesting period relating to such participant’s
grant, the number of RSUs or PSUs, respectively, as determined by their respective formula set out in the 2016 Plan will become vested at the end of the
vesting period.

In the event a participant’s employment is terminated for cause, share units that have not vested prior to the date of the termination for cause will not vest and
all such share units will be forfeited immediately.

Restricted Stock

Restricted stock means common shares that are subject to restrictions on such participant’s free enjoyment of the common shares granted, as determined by
the Board. Notwithstanding the restrictions, the participant will receive dividends paid on the restricted stock, will receive proceeds of the restricted stock in
the event of any change in the common shares and will be entitled to vote the restricted stock during the restriction period.

The participant will not have rights to sell, transfer or assign, or otherwise dispose of the shares of restricted stock or any interest therein while the restrictions
remain in effect. Grants of restricted stock will be forfeited if the applicable restriction does not lapse prior to such date or occurrence of such event or the
satisfaction of such other criteria as is specified in the grant agreement.

No restricted stock has been issued through December 31, 2019.

The intrinsic value of outstanding options at December 31, 2019 was $0 (the intrinsic value of vested options was $0 and the intrinsic value of those expected
to vest was $0). The fair value of the vested RSU’s was $1,153 for the year ended December 31, 2019. There were no options exercised for the year ended
December 31, 2019 and the intrinsic value of exercised options was not significant for the year ended December 31, 2018.

In  determining  the  amount  of  stock-based  compensation  the  Company  used  the  Black-Scholes  option  pricing  model  to  establish  the  fair  value  of  options
granted by applying the following weighted average assumptions:

Volatility
Risk free interest rate
Expected term in years
Expected dividend yield
Weighted average fair value per option

  $

114.68%

The volatility was based on an average of volatility rates of a pool of public pharmaceutical or biotechnology companies that are at a comparable stage of
development and the Company’s recent historic volatility, all calculated taking into account the expected term of the option.

The risk-free rate was based on rates provided by the United States Treasury with a term equal to the expected life of the option.

The Company does not have sufficient historical exercise data to provide a reasonable basis upon which to estimate expected term due to the limited period of
time  its  equity  shares  have  been  publicly  traded.  As  a  result,  the  Company  uses  the  simplified  method  to  determine  the  expected  term  of  stock  options
whereby the expected term equals the average between the vesting period and the contractual life.

The fair value of the options is recognized as an expense on a straight-line basis over the vesting period, forfeitures are accounted for when they occur.

The total stock-based compensation expense recorded in the years ended December 31, was as follows:

period of 1.88 years.

The  number  of  restricted  stock  awards  vested  during  the  year  ended  December  31,  2019  and  2018  includes  no  shares  and  9,281  shares  withheld  or

Collaboration and License Agreement – Brii Bio

On December 4, 2018, we entered into the License Agreement with Brii Bio, whereby:

● the Company and Brii Bio agreed to collaborate on the development of a hepatitis B recombinant protein-based immunotherapeutic in the licensed
territory, which consists of China, Hong Kong, Taiwan and Macau (collectively, the “Licensed Territory”), and to conduct a Phase II collaboration
clinical trial for the purpose of comparing VBI-2601 (BRII-179), which is a recombinant protein-based immunotherapeutic developed by VBI for
use in treating chronic hepatitis B, with a novel composition developed jointly with Brii Bio (either being the “Licensed Product”); and

● The Company granted Brii Bio an exclusive royalty-bearing license to perform studies, and regulatory and other activities, as may be required to
obtain and maintain marketing approval of the Licensed Product, for the treatment of hepatitis B in the Licensed Territory and to commercialize and
the Licensed Product for the diagnosis and treatment of chronic hepatitis B in the Licensed Territory

Pursuant to the License Agreement, the Company is responsible for the R&D Services and Brii Bio is responsible for costs relating to the clinical trials for the
Licensed Territory.

The initial consideration of the License Agreement consisted of a $11 million non-refundable upfront payment. As part of License Agreement, the Company
and Brii Bio entered into a stock purchase agreement. Under the terms of the stock purchase agreement, the Company issued to Brii Bio 2,295,082 shares of
its common stock valued at $3.6 million (based on the Company’s common stock price on December 4, 2018). See Note 11. The remaining $7.4 million,
deemed to be the initial transaction price, was allocated to two performance obligations: i) the VBI-2601 (BRII-179) license and ii) R&D services. The R&D
services  were  allocated  $4.8  million  of  the  transaction  price  using  an  estimated  selling  price  based  on  an  expected  cost  plus  a  margin  approach  and  the
remaining transaction price of $2.6 million was allocated to the VBI-2601 (BRII-179) license using the residual method.

In addition, the Company is also eligible to receive an additional $117.5 million in potential regulatory and sales milestone payments, along with royalties on
commercial sales in the Licensed Territory. Milestone payments that are not within the control of the Company or the licensee, such as regulatory approvals,
are not considered probable of being achieved until those approvals are received. Therefore, no variable consideration was included in the initial transaction
price and no such amounts have been recognized to date.

On December 4, 2018, the Company recognized the VBI-2601 (BRII-179) license when it was transferred and Brii Bio is able to use and benefit from the
license, as it was determined to be distinct. The R&D Services will be satisfied over time as services are rendered using the “cost-to-cost” input method as
this method represents the most accurate depiction of the transfer of services based on the types of costs expected to be incurred. As of December 31, 2019
R&D services related Brii Bio that remain unsatisfied are $3.1 million, out of the $3.8 million total deferred revenue.

Upon termination of the License Agreement prior to the end of the term, there is no obligation for refund and any amounts in deferred revenue related to
unsatisfied performance obligations will be immediately recognized.

Prior to us entering into the License Agreement, the Company paid $6 million to terminate a distribution agreement with a third party who previously held
certain distribution rights to certain Asian markets. This amount is included in general and administrative expenses for the year ended December 31, 2018.

13. COLLABORATIVE ARRANGEMENTS

GlaxoSmithKline Biologicals S.A. (“GSK”)

On September 10, 2019, we entered into a Clinical Collaboration Agreement (“Collaboration Agreement”) pursuant to which we will investigate the use of
GSK’s proprietary AS01B adjuvant system in our ongoing study of VBI-1901. As a result of the Collaboration Agreement, a second study arm was added to
Part B of the ongoing Phase Ib/IIa clinical study to accommodate the AS01B adjuvant.

This relationship is considered a collaborative relationship and not a customer relationship, and is therefore accounted for outside the scope of ASC Topic
606.  Costs  associated  with  the  second  study  arm  will  be  expensed  as  incurred  in  Research  and  Development  expenses;  year  to  date  costs  have  been  de
minimis.

Brii Biosciences Limited

On December 4, 2018, we entered into a License Agreement with Brii Bio, as described in Note 12.

As of December 31, 2019, and 2018, the Company had United States federal net operating loss carryovers (“NOLs”) of approximately $49.8 million and
$39.0 million, respectively, including $29.0 million related to the acquisition of VBI DE, available to offset taxable income which expire beginning in 2026.
The NOLs may be limited pursuant to Section 382 of the Internal Revenue Code and similar state statutes due to the acquisition of VBI DE in 2016 and other
equity transactions through December 31, 2019. Generally, NOL utilization is limited if a corporation has a more than 50% change in ownership over a three-
year  period.  The  Company  plans  on  undertaking  a  detailed  analysis  of  any  historical  and/or  current  Section  382  ownership  changes  that  may  limit  the
utilization of the net operating loss carryovers.

As  of  December  31,  2019,  and  2018,  the  Company  also  had  Canadian  net  operating  loss  carryovers  of  approximately  $52.3  million  and  $47.0  million,
respectively available to offset future taxable income which expire beginning in 2024. As of December 31, 2019, and 2018, the Company also had Israel net
operating loss carryovers of approximately $116.8 million and $80.3 million, respectively, which can be carried forward indefinitely.

At  December  31,  2019  and  2018,  the  Company  had  $5.5  million  and  $4.9  million,  respectively,  of  investment  tax  credits  available  to  carry  forward  and
reduce future years’ Canadian income taxes which expire beginning in 2026.

As of December 31, 2019, and 2018, the Company had unclaimed research and development expenses in Canada of approximately $19.9 million and $17.2
million, respectively, which are available to offset future taxable income indefinitely.

15. COMMITMENTS AND CONTINGENCIES

Licensing

(a)

In connection with the acquisition of the ePixis technology in 2011, VBI Cda also agreed to make certain contingent payments as follows:

Upon  the  completion  of  a  “Successful  Technology  Transfer”,  as  defined  in  the  Sale  and  Purchase  Agreement  (“SPA”),  to  a  contract  manufacturing
organization, VBI Cda paid €102 (approximately $110 and referred to as the “Transfer Payment”) to the Sellers during the second quarter of 2015. The
Transfer Payment related to the achievement of the first milestone, which occurred during the three months ended June 30, 2015.

The Company is committed to make further contingent payments pursuant to defined milestones in the SPA depending on whether there continue to exist
any issued and valid claims on the acquired patents. Contingent payments include:

●

●

Upon first approval in the United States or the European Union: €500 to €1,000;

Upon commercialization when cumulative net sales equals or exceeds:

○

○

€25,000: €750 to €1,500; and,

€50,000: €1,000 to €2,000;

Upon commercialization by one or more sublicenses when cumulative net sales equals or exceeds:

○

○

○

○

○

€25,000: €375 to €750;

€50,000: €375 to €750;

€75,000: €500 to €1,000;

€100,000: €500 to €1,000,

VBI will be obligated to pay to the Sellers the balance still owing on the total €3,500 when either cumulative net sales of €50,000
by VBI or €100,000 by VBI and its sublicenses is achieved.

The  Company  is  further  committed  to  pay  all  costs  of  protecting  the  patents  and  make  contingent  payments  to  the  licensor  of  the  acquired  patents
pursuant  to  defined  milestones  in  an  amendment  to  the  related  license  agreement  which  include:  royalty  fees  ranging  between  0.75%  and  1.75%
depending on the level of net sales; and, lump sum payments ranging from €50 to €1,000 depending on the stage of clinical development and ultimately
commercial approval. Additionally, 5% to 25% of any sublicensing fees depending on stage of clinical development are also payable to the licensor.

Except for the Transfer Payment, which became due upon successful technology transfer to a contract manufacturing organization, the events obliging
the Company to make these payments to the Sellers have not yet occurred and are not probable of occurring; consequently, no amounts are accrued in
respect of these contingencies.

(b) The Company’s manufactured and marketed product, Sci-B-Vac is a recombinant trivalent hepatitis B vaccine whose sales and territories are governed by
the Savient Pharmaceuticals Inc and SciGen Ltd., dated June 2014 (“Ferring License Agreement”). Under the Ferring License Agreement the Company
is committed to pay Ferring royalties equal to 7% of net sales (as defined therein) of the HBsAg “Product” (as defined therein). Under an Assignment
Agreement between FDS Pharm LLP and SciGen Ltd., dated February 14, 2012 (the “SciGen Assignment Agreement”), we are required to pay royalties
to SciGen Ltd. equal to 5% of net sales (as defined in the Ferring License Agreement) of Product.

Royalty payments under the Ferring License Agreement of $38 and $42, were recorded in cost of revenues for the year ended December 31, 2019 and
2018, respectively.

Royalty payments under the SciGen Assignment Agreement of $27 and $30 were recorded in cost of revenues for the year ended December 31, 2019 and
2018, respectively.

In addition, the Company is committed to pay 30% of any and all non-royalty consideration, in any form, received by Company from sub-licensees (other
than consideration based on net sales for which a royalty is due under the Ferring License Agreement), provided that the payment of 30% shall not apply
to a grant of rights in or relating to: (i) the territory as such term was defined prior to an amendment dated January 24, 2005; or (ii) the Berna Territory
(as defined in therein).

Under the Ferring License Agreement and the SciGen Assignment Agreement, we originally were to pay royalties on a country-by-country basis until the
date 10 years after the date of commencement of the first royalty year in respect of such country. In April 2019, we exercised our option to extend the
Ferring  License  Agreement  in  respect  of  all  the  countries  that  still  make  up  the  territory  for  an  additional  7  years  by  making  a  one-time  payment  to
Ferring of $100. Royalties under the Ferring License Agreement and SciGen Assignment Agreement will continue to be payable for the duration of the
extended license periods.

Legal Proceedings

From time to time, the Company may be involved in certain claims and litigation arising out of the ordinary course and conduct of business. Management
assesses such claims and, if it considers that it is probable that an asset had been impaired or a liability had been incurred and the amount of loss can be
reasonably estimated, provisions for loss are made based on management’s assessment of the most likely outcome.

On September 13, 2018, two actions were brought in the District Court of the central district in Israel naming our subsidiary SciVac as a defendant. In one
claim,  two  minors,  through  their  parents,  allege  among  other  things,  defects  in  certain  batches  of  Sci-B-Vac  discovered  in  July  2015;  that  Sci-B-Vac  was
approved for use in children and infants in Israel without sufficient evidence establishing its safety; that SciVac failed to provide accurate information about
Sci-B-Vac to consumers and that each child suffered side effects from the vaccine. The claim was filed together with a motion seeking approval of a class
action on behalf of 428,000 children vaccinated with Sci-B-Vac in Israel from April, 2011 and seeking damages in a total amount of NIS 1,879,500,000 (not
in thousands) ($543,837). The second claim is a civil action brought by two minors and their parents against SciVac and the Israel Ministry of Health alleging,
among other things, that SciVac marketed an experimental, defective, hazardous or harmful vaccine; that Sci-B-Vac was marketed in Israel without sufficient
evidence  establishing  its  safety;  and  that  Sci-B-Vac  was  produced  and  marketed  in  Israel  without  approval  of  a  western  regulatory  body.  The  claim  seeks
damages for past and future losses and expenses as well as punitive damages.

SciVac believes these matters to be without merit and intends to defend these claims vigorously.

The  District  Court  has  accepted  SciVac’s  motion  to  suspend  reaching  a  decision  on  the  approval  of  the  class  action  pending  the  determination  of  liability
under the civil action. Preliminary hearings for the trial of the civil action began on January 15, 2020.

16. LEASES

The  Company  has  entered  into  various  non-cancelable  lease  agreements  for  its  office,  lab  and  manufacturing  facilities,  which  are  classified  as  operating
leases.  The  office  facility  lease  agreement  in  the  United  States  expires  on  April  30,  2020,  with  no  option  to  extend.  Our  manufacturing  facility  lease
agreement expires on January 31, 2022, which includes one five-year option to extend until January 31, 2027. The lease agreement for our research facility in
Canada, which comprises of office and laboratory space, had an initial term ending on December 31, 2019 with the option to extend the term for two periods
of three years. Effective September 5, 2019, the term of the lease was extended until December 31, 2022, with an option to extend the lease for one additional
period of three years.

Options to extend are not recognized as part of the lease liabilities or recognized as right to use assets. There are no residual value guarantees, no variable
lease  payments,  and  no  restrictions  or  covenants  imposed  by  leases.  The  discount  rate  used  in  measuring  the  lease  liabilities  and  right  of  use  assets  was
determined by reviewing our incremental borrowing rate at the initial measurement date.

DESCRIPTION OF VBI VACCINES INC. COMMON SHARES

Exhibit 4.7

The following description of the capital stock of VBI Vaccines Inc. (the “Company,” “VBI,” “we,” “our,” or “us”) is a summary of the rights of our common
shares  and  certain  provisions  of  our  Articles  as  currently  in  effect.  This  summary  does  not  purport  to  be  complete  and  is  qualified  in  its  entirety  by  the
provisions of our Articles, copies of which are filed as exhibits to this Annual Report on Form 10-K and are incorporated by reference herein. We encourage
you to read our Articles and the applicable provisions of British Columbia Business Corporations Act (the “BCBCA”), for additional information.

Description of Common Shares

We are authorized to issue an unlimited number of common shares with no par value. We are governed by the BCBCA and other relevant laws, which may
affect  the  rights  of  shareholders  differently  than  those  of  a  company  governed  by  the  laws  of  a  U.S.  jurisdiction,  and  may,  together  with  our  charter
documents,  including  the  advance  notice  provisions  in  our  Articles  for  the  nomination  of  directors,  have  the  effect  of  delaying,  deferring  or  discouraging
another party from acquiring control of our Company by means of a tender offer, a proxy contest or otherwise, or may affect the price an acquiring party
would be willing to offer in such an instance.

Holders of our common shares are entitled to such dividends as may be declared by our board of directors out of funds legally available for such purpose. The
BCBCA  provides  that  we  may  declare  or  pay  dividends  unless  there  are  reasonable  grounds  for  believing  that  (a)  the  Company  is  insolvent,  or  (b)  the
payment of the dividend would render the Company insolvent.

Each holder of our common shares is entitled to one vote for each such share outstanding in the holder’s name. No holder of common shares is entitled to
cumulate votes in voting for directors.

In  the  event  of  our  liquidation,  dissolution  or  winding  up,  the  holders  of  our  common  shares  are  entitled  to  receive  pro  rata  our  assets  which  are  legally
available for distribution, after payments of all debts and other liabilities.

Our directors may, subject to our Articles and the BCBCA, issue, allot, sell, grant options on or otherwise dispose of the unissued shares, and issued shares
held by the Company, at the times, to the persons, including directors, in the manner, on the terms and conditions and for the issue prices that the directors, in
their absolute discretion, may determine by board resolution. Shares may be issued in consideration for past services, property or money. Shares must not be
issued until they are fully paid. There are no preemptive, redemption, purchase or conversion rights attaching to our common shares. There are no sinking
fund provisions applicable to our common shares. Our common shares are issued in fully registered form, although we are able to issue fractional shares.

Since we are authorized to issue an unlimited number of common shares with no par value, the authorized but unissued common shares are available for
future issuance without any further vote or action by our shareholders. These additional shares may be utilized for a variety of corporate purposes, including
future  public  offerings  to  raise  additional  capital,  corporate  acquisitions,  and  employee  benefit  plans.  The  existence  of  authorized  but  unissued  common
shares could render more difficult or discourage an attempt to obtain control over us by means of a proxy contest, tender offer, merger or otherwise.

Registration Rights

Pursuant to the warrants issued to Perceptive Credit Holdings, LP (the “Lender”) in accordance with that certain Amended and Restated Credit Agreement
and Guaranty, as may be amended from time to time in accordance with its terms, at any time after the one hundred eightieth day following the original issue
date  of  the  warrant,  which  was  December  6,  2016,  the  Lender,  or  its  assignees,  may  request  that  we  register  all  or  any  portion  of  the  common  shares
underlying the warrants for sale on a registration statement under the Securities Act of 1933, as amended (the “Securities Act”).

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
In addition, if at any time we propose to register any of our common shares under the Securities Act for public sale either for our own account or for the
account  of  other  shareholders,  the  holder  of  the  warrants  are  entitled  to  notice  of  the  registration  and  may  request  that  we  include  all  or  a  portion  of  the
common  shares  in  the  registration.  These  piggyback  registration  rights  are  subject  to  specified  conditions  and  limitations,  including  the  right  of  the
underwriters to limit the number of shares included in any such registration under specified circumstances.

Anti-takeover Effects of Provisions of VBI’s Articles and BCBCA, Alterations

The  BCBCA  does  not  contain  a  provision  comparable  to  Section  203  of  the  Delaware  General  Corporation  Law  (DGCL)  with  respect  to  business
combinations.

Under the BCBCA and our Articles, certain extraordinary company alterations, such as changes to authorized share structure, continuances, into or out of
province,  certain  amalgamations,  sales,  leases  or  other  dispositions  of  all  or  substantially  all  of  the  undertaking  of  a  company  (other  than  in  the  ordinary
course of business) liquidations, dissolutions, and certain arrangements are required to be approved by ordinary or special resolution as applicable.

An ordinary resolution is a resolution (i) passed at a shareholders’ meeting by a simple majority, or (ii) passed, after being submitted to all of the shareholders,
by  being  consented  to  in  writing  by  shareholders  who,  in  the  aggregate,  hold  shares  carrying  at  least  two-thirds  of  the  votes  entitled  to  be  cast  on  the
resolution.  A  special  resolution  is  a  resolution  (i)  passed  by  not  less  than  two-thirds  of  the  votes  cast  by  the  shareholders  who  voted  in  respect  of  the
resolution at a meeting duly called and held for that purpose or (ii) signed by all shareholders entitled to vote on the resolution.

Under the BCBCA, an action that prejudices or interferes with a right or special right attached to issued shares of a class or series of shares must be approved
by a special separate resolution of the holders of the class or series of shares being affected.

Under the BCBCA, arrangements are permitted and a company may make any proposal it considers appropriate “despite any other provision” of the BCBCA.
In general, a plan of arrangement is approved by a company’s board of directors and then is submitted to a court for approval. It is not unusual for a company
in such circumstances to apply to a court initially for an interim order governing various procedural matters prior to calling any security holder meeting to
consider the proposed arrangement. Plans of arrangement involving shareholders must be approved by a special resolution of shareholders, including holders
of shares not normally entitled to vote. The court may, in respect of an arrangement proposed with persons other than shareholders and creditors, require that
those persons approve the arrangement in the manner and to the extent required by the court. The court determines, among other things, to whom notice shall
be  given  and  whether,  and  in  what  manner,  approval  of  any  person  is  to  be  obtained  and  also  determines  whether  any  shareholders  may  dissent  from  the
proposed arrangement and receive payment of the fair value of their shares. Following compliance with the procedural steps contemplated in any such interim
order (including as to obtaining security holder approval), the court would conduct a final hearing and approve or reject the proposed arrangement.

The BCBCA does not contain a provision comparable to Section 251(h) of the DGCL.

Election and removal of directors

According to our Articles, all directors cease to hold office immediately before the election or appointment of directors at every annual general meeting, but
are eligible for re-election or re- appointment. Under Section 14.10 of VBI’s Articles, shareholders of VBI may remove any director before the expiration of
his  or  her  term  of  office  by  a  special  resolution  of  shareholders.  This  system  of  electing  and  removing  directors  generally  makes  it  more  difficult  for
shareholders to replace a majority of our directors.

Shareholder action; advance notification of stockholder nominations and proposals

Under the BCBCA, the holders of not less than 5% of our common shares may requisition that the directors call a meeting of shareholders for the purpose of
transacting any business that may be transacted at a general meeting. Upon receiving a requisition that complies with the technical requirements set out in the
BCBCA,  the  directors  must,  subject  to  certain  limited  exceptions,  call  a  meeting  of  shareholders  to  be  held  not  more  than  4  months  after  receiving  the
requisition. If the directors do not call such a meeting within 21 days after receiving the requisition, the requisitioning shareholders or any of them holding in
aggregate not less than 2.5% of the issued shares of the Company that carry the right to vote at general meetings may call the meeting.

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Under the BCBCA, shareholder proposals may be made by registered or beneficial owners of shares entitled to vote at general meetings of shareholders who
have been the registered or beneficial owner of such shares for an uninterrupted period of at least two years before the date of signing of the proposal, and
who together in the aggregate constitute at least 1% of the issued shares that carry on the right to vote at general meetings or have a fair market value of
shares in excess of CAD$2,000. Those registered or beneficial holders must, alongside the proposal, submit and sign a declaration providing the requisite
information under the BCBCA. To be a valid proposal, the proposal must be submitted at least three months before the anniversary of the previous year’s
annual reference date.

Under the advance notice provisions contained in Section 10.9 of VBI’s Articles, subject only to the BCBCA, only persons who are nominated in accordance
with the procedures set forth therein shall be eligible for election as directors of the Company. Nominations of persons for election to the Board may be made
at any annual meeting of shareholders, or at any special meeting of shareholders if one of the purposes for which the special meeting was called was the
election of directors: (a) by or at the direction of the Board, including pursuant to a notice of meeting; (b) by or at the direction or request of one or more
shareholders pursuant to a proposal made in accordance with the provisions of the BCBCA, or a requisition of the shareholders made in accordance with the
provisions of the BCBCA; or (c) by any person (a “Nominating Shareholder”): (A) who, at the close of business on the date of the giving of the notice and on
the record date for notice of such meeting, is entered in the securities register as a holder of one or more shares carrying the right to vote at such meeting or
who beneficially owns shares that are entitled to be voted at such meeting; and (B) who complies with the notice procedures set forth in our Articles.

In addition to any other applicable requirements, for a nomination to be made by a Nominating Shareholder, the Nominating Shareholder must have given
timely notice thereof in proper written form to the Secretary of the Company at the principal executive offices of the Company.

To  be  timely,  a  Nominating  Shareholder’s  notice  to  the  Secretary  of  the  Company  must  generally  be  made:  (a)  in  the  case  of  an  annual  meeting  of
shareholders, not less than 30 nor more than 65 days prior to the date of the annual meeting of shareholders.

These  provisions  may  have  the  effect  of  deterring  unsolicited  offers  to  acquire  the  Company  or  delaying  changes  in  control  of  our  management.  These
provisions  could  also  have  the  effect  of  delaying  until  the  next  shareholder  meeting  any  shareholder  actions,  even  if  they  are  favored  by  the  holders  of  a
majority of our outstanding voting securities.

Amendment to Articles

Under the BCBCA, a company may amend its articles or notice of articles by (i) the type of resolution specified in the BCBCA, (ii) if the BCBCA does not
specify a type of resolution, then by the type specified in the company’s articles, or (iii) if the company’s articles do not specify a type of resolution, then by
special resolution. The BCBCA permits many substantive changes to a company’s articles (such as a change in the company’s authorized share structure or a
change  in  the  special  rights  or  restrictions  that  may  be  attached  to  a  certain  class  or  series  of  shares)  to  be  changed  by  the  resolution  specified  in  that
company’s articles.

Our Articles provide that, subject to the BCBCA, certain alterations to our share structure be done by way of directors’ resolution. Any creation, variation or
deletion of special rights and restrictions attached to a series or class of shares must be done by way of special resolution.

Our Articles also provide that, the shareholders may from time to time, by ordinary resolution, make any alteration to our notice of articles and articles as
permitted by the BCBCA.

 
 
 
 
 
 
 
 
 
 
 
 
 
 
Limitation of Liability and Indemnification

Section 21.2 of VBI’s Articles requires VBI, subject to the BCBCA, to indemnify a director, former director or alternate director and his or her heirs and legal
representatives  against  all  eligible  penalties  to  which  such  person  is  or  may  be  liable  and  after  the  disposition  of  an  eligible  proceeding  pay  the  expenses
actually and reasonably incurred by such person in respect of that proceeding.

Pursuant to Section 21.3 of VBI’s Articles, VBI may indemnify any person subject to the restrictions of the BCBCA.

Pursuant to Section 162 of the BCBCA, prior to the final disposition, VBI may pay, as they are incurred, the expenses actually and reasonably incurred by an
eligible  party,  or  the  heirs  and  personal  or  other  legal  representatives  in  respect  of  that  proceeding,  if  VBI  first  receives  from  such  person  a  written
undertaking that if the indemnification is ultimately determined to be prohibited pursuant to the BCBCA, such person will repay the amounts advanced.

Indemnification  under  the  BCBCA  is  prohibited  if  any  of  the  following  circumstances  apply:  (1)  if  the  indemnity  or  payment  is  made  under  an  earlier
agreement  and  at  the  time  the  agreement  to  indemnify  or  pay  expenses  was  made  the  company  was  prohibited  from  doing  so  under  its  memorandum  or
articles; (2) if the indemnity or payment is made otherwise than under an earlier agreement and at the time the indemnity or payment is made, the company is
prohibited from doing so under its memorandum or articles; (3) if, in relation to the subject matter of the eligible proceeding, the eligible party did not act
honestly and in good faith with a view to the best interests of the company or the associated corporation; or (4) in the case of an eligible proceeding other than
a civil proceeding, if the eligible party did not have reasonable grounds for believing that the eligible party’s conduct in respect of which the proceeding was
brought was lawful.

If an eligible proceeding is brought against an eligible party, or the heirs and personal or other legal representatives in respect of that proceeding, by or on
behalf of VBI or an associated corporation, VBI must not indemnify that person for any penalties such person is or may be liable for and must not pay the
expenses of that person in respect of the proceeding.

In  addition,  on  the  application  of  VBI  or  an  eligible  party,  a  court  may:  (a)  order  VBI  to  indemnify  an  eligible  party  against  any  liability  incurred  by  the
eligible party in respect of an eligible proceeding; (b) order VBI to pay some or all of the expenses incurred by an eligible party in respect of an eligible
proceeding; (c) order the enforcement of, or any payment under, an agreement of indemnification entered into by VBI; (d) order VBI to pay some or all of the
expenses actually and reasonably incurred by any person in obtaining an order under the BCBCA; (e) make any other order the court considers appropriate.

Control Block Distributions

Under applicable securities laws in Canada, any person (or group of persons) who owns a sufficient number of any of the securities of an issuer so as to affect
materially the control of that issuer is considered to be a “control person”. For such purposes, any person who has or acquires control or direction over more
than 20% of the voting securities of an issuer will be deemed, in the absence of evidence to the contrary, to be a “control person”. Any “trade” of securities by
a control person is considered to be a “distribution”, and accordingly, the disposition of such securities must be qualified by a prospectus, absent an available
exemption.

Certain Takeover Bid Requirements

Any offer made by a person (an “offeror”) to acquire outstanding shares of a Canadian entity that, when aggregated with the offeror’s holdings (and those of
persons or companies acting jointly with the offeror), would constitute 20% or more of the outstanding shares, would be subject to the take-over provisions of
Canadian securities laws, unless the offer constitutes an exempt transaction.

In addition to those take-over bid requirements noted above, the acquisition of shares may trigger the application of additional statutory regimes including
amongst others, the Investment Canada Act and the Competition Act (Canada).

Listing

Our common shares are listed for trading on the NASDAQ Capital Market under the symbol “VBIV.”

Transfer Agent and Registrar

The transfer agent and registrar for our common shares is Computershare. Its address is 510 Burrard Street, 2nd Floor, Vancouver, British Columbia V6C
3B9, and its telephone number is (604) 661-9442.

This summary is not a comprehensive description of relevant or applicable considerations regarding such requirements and, accordingly, is not intended to be,
and  should  not  be  interpreted  as,  legal  advice  to  any  prospective  purchaser  and  no  representation  with  respect  to  such  requirements  to  any  prospective
purchaser  is  made.  Prospective  investors  should  consult  their  own  Canadian  legal  advisors  with  respect  to  any  questions  regarding  securities  law  in  the
provinces and territories of Canada.

respect to the 2019 Audited Financial Statements will contain an Impermissible Qualification;

ANNEX A
REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Stockholders of
VBI Vaccines, Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of VBI Vaccines Inc. and Subsidiaries (the “Company”) as of December 31, 2019 and 2018,
and the related consolidated statements of operations and comprehensive loss, stockholders’ equity, and cash flows for each of the years then ended, and the
related  notes  (collectively  referred  to  as  the  “financial  statements”).  In  our  opinion,  the  financial  statements  present  fairly,  in  all  material  respects,  the
consolidated financial position of the Company as of December 31, 2019 and 2018, and the consolidated results of their operations and their cash flows for
each of the years then ended, 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  1  to  the
financial statements, the Company has incurred, and it anticipates it will continue to incur, significant losses and generate negative operating cash flows and
as such will require significant additional funds to continue its development activities to ultimately achieve commercial launch of its products. These factors
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  1.  The
financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Basis for Opinion

These  financial  statements  are  the  responsibility  of  the  Company’s  management.  Our  responsibility  is  to  express  an  opinion  on  the  Company’s  financial
statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”)
and are required to be independent with respect to the Company in accordance with the United States 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. The Company is not required to have, nor
were  we  engaged  to  perform,  an  audit  of  its  internal  control  over  financial  reporting.  As  part  of  our  audits  we  are  required  to  obtain  an  understanding  of
internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial
reporting. Accordingly, we express no such opinion.

Our  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.

We have served as the Company’s auditor since 2016.

CONSENT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
