All forward-looking statements involve risks, assumptions and uncertainties. You should not rely upon forward-looking statements as predictors of
future events. The occurrence of the events described, and the achievement of the expected results, depend on many events, some or all of which are not
predictable or within our control. Actual results may differ materially from expected results. See the sections “Item 3. Key Information-D. Risk Factors,”
“Item 5. Operating and Financial Review and Prospectus” and elsewhere in this Annual Report for a more complete discussion of these risks, assumptions
and  uncertainties  and  for  other  risks  and  uncertainties.  These  risks,  assumptions  and  uncertainties  are  not  necessarily  all  of  the  important  factors  that
could cause actual results to differ materially from those expressed in any of our forward-looking statements. Other unknown or unpredictable factors also
could harm our results.

All of the forward-looking statements we have included in this Annual Report are based on information available to us on the date of this Annual
Report.  We  undertake  no  obligation,  and  specifically  decline  any  obligation,  to  update  publicly  or  revise  any  forward-looking  statements,  whether  as  a
result of new information, future events or otherwise. In light of these risks, uncertainties and assumptions, the forward-looking events discussed in this
Annual Report might not occur.

The audited financial statements for the years ended December 31, 2020, 2019 and 2018 in this Annual Report have been prepared in accordance

in accordance with U.S. GAAP.

D. Risk Factors

You  should  consider  carefully  the  risks  and  uncertainties  described  below,  together  with  all  of  the  other  information  in  this  Annual  Report,
including the financial statements and the related notes included elsewhere in this Annual Report. The risks and uncertainties described below are not the
only ones we face. Additional risks and uncertainties that we are unaware of, or that we currently believe are not material, may also become important
factors that adversely affect our business. If any of the following risks actually occurs, our business, financial condition, results of operations, and future
prospects could be materially and adversely affected.

Risks Related to Our Financial Condition and Capital Requirements

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

We are a clinical-stage biotechnology company, and we have not yet generated any regular revenue streams. We have incurred losses in each year since our
inception  in  2000,  including  net  losses  of  $24.2  million,  $19.4  million  and  $20.5  million  for  the  years  ended  December  31,  2020,  2019  and  2018,
respectively. As of December 31, 2020, we had an accumulated deficit of $232.2 million.

We have devoted most of our financial resources to research and development, including our clinical and preclinical development activities. To date, we
have financed our operations primarily through the sale of equity securities and convertible debt and, to a lesser extent, through grants from governmental
agencies. The amount of our future net losses will depend, in part, on the rate of our future expenditures and our ability to obtain funding through equity or
debt financings, strategic collaborations or additional grants. We have completed only a single pivotal clinical trial for our product candidates and it will be
a few years, if ever, before we have a product candidate ready for commercialization. Even if we obtain regulatory approval to market a product candidate,
our future revenues will depend upon the size of any markets in which our product candidates have received approval, and our ability to achieve sufficient
market acceptance, reimbursement from third-party payors and adequate market share for our product candidates in those markets.

We expect to continue to incur significant expenses and increasing operating losses for the foreseeable future. We anticipate that our expenses will increase
substantially if and as we:

●

●

●

●

●

●

●

●

●

●

continue our research and preclinical and clinical development of our product candidates;

expand the scope of our current clinical trials for our product candidates;

initiate additional preclinical, clinical or other studies for our product candidates;

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

further develop the manufacturing process for our product candidates;

operate and possibly expand our new, commercial scale manufacturing facility;

change or add additional manufacturers or suppliers;

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

seek to identify and validate additional product candidates;

acquire or in-license other product candidates and technologies;

Table of Contents

●

●

●

●

●

make  milestone  or  other  payments  under  any  in-license  or  other  intellectual  property  related  agreements,  including  our  agreement  with  Tel
Hashomer-Medical Research, Infrastructure and  Services  Ltd.  and  our  license  from  Janssen  Vaccines  &  Prevention  B.V.,  or  Janssen  (formerly
known as Crucell Holland B.V.), and any other licensing arrangements we may enter into the future;

maintain, protect and expand our intellectual property portfolio;

attract and retain skilled personnel;

create additional infrastructure to support our operations as a public company; and

experience any delays or encounter issues with any of the above.

The  net  losses  we  incur  may  fluctuate  significantly  from  quarter  to  quarter  and  year  to  year,  such  that  a  period-to-period  comparison  of  our  results  of
operations  may  not  be  a  good  indication  of  our  future  performance.  In  any  particular  quarter  or  quarters,  our  operating  results  could  be  below  the
expectations of securities analysts or investors, which could cause our share price to decline.

We have never generated any revenue from product sales and may never be profitable.

Our ability to generate revenue and achieve profitability depends on our ability, alone or with strategic collaboration partners, to successfully complete the
development of, obtain the regulatory approvals of, and commercialize our product candidates. We do not anticipate generating revenues from product sales
for the foreseeable future, if ever. Our ability to generate future revenues from product sales depends heavily on our success in:

●

●

●

●

●

●

●

●

●

●

●

●

●

completing research and preclinical and clinical development of our product candidates;

seeking and obtaining regulatory and marketing approvals for product candidates for which we complete clinical trials;

developing a sustainable, scalable, reproducible, and transferable manufacturing process for our product candidates;

establishing and maintaining supply and manufacturing relationships with third parties that can provide products and services adequate, in amount
and quality, to support clinical development and the market demand for our product candidates, if approved;

and/or successfully  establishing,  validating  and  operating  our  own  manufacturing  facilities  to  produce  our  products  in  amount  and  quality,  to
support clinical development and the market demand for our product candidates, if approved, as well as passing inspections by health authorities,
such as the Food and Drug Administration, or FDA, and European Medicines Agency, or EMA, and obtaining approval for our manufacturing
facility and product;

launching and  commercializing  any  product  candidates  for  which  we  obtain  regulatory  and  marketing  approval,  either  by  collaborating  with  a
partner or, if launched independently, by establishing a sales, marketing and distribution infrastructure;

obtaining market acceptance of any product candidates that receive regulatory approval as viable treatment options;

addressing any competing technological and market developments;

implementing additional internal systems and infrastructure, as needed;

identifying and validating new product candidates;

negotiating favorable terms in any collaboration, licensing or other arrangements into which we may enter;

maintaining, protecting and expanding our portfolio of intellectual property rights, including patents, trade secrets and know-how; and

attracting, hiring and retaining qualified personnel.

Even if one or more of our product candidates is approved for commercial sale, we anticipate incurring significant costs associated with commercializing
any approved product candidate. Our expenses could increase beyond expectations if we are required by the FDA, the EMA, or other regulatory agencies,
domestic or foreign, to perform clinical and other studies in addition to those that we currently anticipate. Even if we are able to generate revenues from the
sale of any approved products, we may not become profitable and may need to obtain additional funding to continue operations.

We may need to raise additional funding, which may not be available on acceptable terms, or at all. Failure to obtain this necessary capital when
needed may force us to delay, limit or terminate our product development efforts or other operations.

We are currently advancing VB-111 for solid cancer indications. We intend to advance this current clinical product candidate through clinical development
and other product candidates through preclinical and clinical development. Developing pharmaceutical products is expensive, and we expect our research
and development expenses to increase substantially in connection with our ongoing activities, particularly as we advance our product candidates in clinical
trials.

As of December 31, 2020, our cash and cash equivalents and short-term bank deposits were $30.8 million. As of March 15, 2021, we estimate that the
balance of cash, cash equivalents and short-term bank deposits at December 31, 2020 together with the funds received from the exercise of warrants, the
share  purchases  by  Aspire  Capital  LLC  and  the  share  sales  on  the  ATM  plan  will  be  sufficient  to  fund  our  operations  into  the  fourth  quarter  of  2022.
However,  our  operating  plan  may  change  as  a  result  of  many  factors  currently  unknown  to  us,  and  we  may  need  to  seek  additional  funds  sooner  than
planned through public or private equity or debt financings, government or other third-party funding, marketing and distribution arrangements and other
collaborations, strategic alliances and licensing arrangements or a combination of these approaches. In any event, we might require additional capital to
obtain regulatory approval for our product candidates, and to commercialize any that receive regulatory approval. Raising funds in the current economic
environment may present additional challenges. Global health concerns resulting from the outbreak of the coronavirus in China and worldwide may have
long-term lasting effects on our ability to raise capital, many of which are difficult for us to predict at this time. Even if we believe we have sufficient funds
for our current or future operating plans, we may seek additional capital if market conditions are favorable or if we have specific strategic considerations.

Any  additional  fundraising  efforts  may  divert  our  management  from  their  day-to-day  activities,  which  may  compromise  our  ability  to  develop  and
commercialize our product candidates. In addition, we cannot guarantee that future financing will be available in sufficient amounts or on terms acceptable
to us, if at all. Moreover, the terms of any financing may adversely affect the holdings or the rights of our shareholders, and the issuance of additional
securities,  whether  equity  or  debt,  by  us,  or  the  possibility  of  such  issuance,  may  cause  the  market  price  of  our  ordinary  shares  to  decline.  The  sale  of
additional  equity  or  convertible  securities  would  dilute  all  of  our  shareholders.  The  incurrence  of  indebtedness  would  result  in  increased  fixed  payment
obligations and we may be required to agree to certain restrictive covenants such as limitations on our ability to incur additional debt, limitations on our
ability to acquire, sell or license intellectual property rights and other operating restrictions that could adversely impact our ability to conduct our business.
We  could  also  be  required  to  seek  funds  through  arrangements  with  collaborative  partners  or  otherwise  at  an  earlier  stage  than  otherwise  would  be
desirable, and we may be required to relinquish rights to some of our technologies or product candidates or otherwise agree to terms unfavorable to us.

If  we  are  unable  to  obtain  funding  on  a  timely  basis,  we  may  be  required  to  significantly  curtail,  delay  or  discontinue  one  or  more  of  our  research  or
development programs or the commercialization of any product candidates, and we may be unable to expand our operations or otherwise capitalize on our
business opportunities, as desired.

We have received and may continue to receive Israeli governmental grants to assist in the funding of our research and development activities. If
we lose our funding from these research and development grants, we may encounter difficulties in the funding of future research and development
projects and implementing technological improvements, which would harm our operating results.

Through December 31, 2020 we had received an aggregate of $28.8 million in the form of grants from the Israeli Office of the Chief Scientist, or OCS,
which  has  later  transformed  to  the  Israeli  Innovation  Authority,  or  IIA.  The  requirements  and  restrictions  for  such  grants  are  found  in  the  Israel
Encouragement  of  Research  and  Development  in  Industries,  or  the  Research  Law.  Under  the  Research  Law,  royalties  of  3%  to  3.5%  on  the  revenues
derived from sales of products or services developed in whole or in part using these IIA grants are payable to the Israeli government. We developed both of
our platform technologies, at least in part, with funds from these grants, and accordingly we would be obligated to pay these royalties on sales of any of our
product candidates that achieve regulatory approval. The maximum aggregate royalties paid generally cannot exceed 100% of the grants made to us, plus
annual interest equal to the 12-month LIBOR applicable to dollar deposits, as published on the first business day of each calendar year. As of December 31,
2020, the balance of the principal and interest in respect of our commitments for future payments to the IIA totaled approximately $36.0 million. To date,
we have paid the IIA in relation to our licenses agreement royalties of approximately $0.5 million. As part of funding our current and planned product
development activities, we submitted follow-up grant application.

These  grants  have  funded  some  of  our  personnel,  development  activities  with  subcontractors  and  other  research  and  development  costs  and  expenses.
However, if these awards are not funded in their entirety or if new grants are not awarded in the future, due to, for example, IIA budget constraints or
governmental policy decisions, our ability to fund future research and development and implement technological improvements would be impaired, which
would negatively impact our ability to develop our product candidates.

Table of Contents

The  Israeli  government  grants  we  have  received  for  research  and  development  expenditures  restrict  our  ability  to  manufacture  products  and
transfer technologies outside of Israel and require us to satisfy specified conditions. If we fail to satisfy these conditions, we may be required to
refund grants previously received together with interest and penalties.

Our research and development efforts have been financed, in part, through the grants that we have received from the IIA. We, therefore, must comply with
the requirements of the Research Law.

Under the Research Law, we are required to manufacture the major portion of each of our products developed using these grants in the State of Israel or
otherwise ask for special approvals. We may not receive the required approvals for any proposed transfer of manufacturing activities. Even if we do receive
approval to manufacture products developed with government grants outside of Israel, the royalty rate may be increased and we may be required to pay up
to 300% of the grant amounts plus interest, depending on the manufacturing volume that is performed outside of Israel. This restriction may impair our
ability to outsource manufacturing or engage in our own manufacturing operations for those products or technologies. See “Item 5. Operating and Financial
Review and Prospects-Financial Overview-Research and Development Expenses” for additional information.

Additionally,  under  the  Research  Law,  we  are  prohibited  from  transferring,  including  by  way  of  license,  the  IIA-financed  technologies  and  related
intellectual property rights and know-how outside of the State of Israel, except under limited circumstances and only with the approval of the IIA Research
Committee. We may not receive the required approvals for any proposed transfer and, even if received, we may be required to pay the IIA a portion, to be
set  by  the  IIA  upon  their  approval  of  such  transaction,  of  the  consideration  or  milestone  and  royalties  payments  that  we  receive  upon  any  sale  or  out
licensing of such technology to a non-Israeli entity, up to 600% of the grant amounts plus interest. The scope of the support received, the royalties that we
have already paid to the IIA, the amount of time that has elapsed between the date on which the know-how or the related intellectual property rights were
transferred and the date on which the IIA grants were received and the sale price and the form of transaction will be taken into account in order to calculate
the amount of the payments to the IIA. Approval of the transfer of technology to residents of the State of Israel is required, and may be granted in specific
circumstances only if the recipient abides by the provisions of applicable laws, including the restrictions on the transfer of know-how and the obligation to
pay royalties. No assurance can be made that approval to any such transfer, if requested, will be granted.

These  restrictions  may  impair  our  ability  to  sell  our  technology  assets  or  to  perform  or  outsource  manufacturing  outside  of  Israel,  engage  in  change  of
control  transactions  or  otherwise  transfer  our  know-how  outside  of  Israel  and  may  require  us  to  obtain  the  approval  of  the  IIA  for  certain  actions  and
transactions and pay additional royalties and other amounts to the IIA. In addition, any change of control and any change of ownership of our ordinary
shares that would make a non-Israeli citizen or resident an “interested party,” as defined in the Research Law, requires prior written notice to the IIA, and
our failure to comply with this requirement could result in criminal liability.

These restrictions will continue to apply even after we have repaid the full amount of royalties on the grants. For the years ended December 31, 2020, 2019
and, 2018, we recorded grants totaling $1.5 million, $2.7 million, and $2.0 million from the IIA, respectively. The grants represented an approximately 7%,
15%, and 11% respectively, of our gross research and development expenditures for the years ended December 31, 2020, 2019 and, 2018. If we fail to
satisfy the conditions of the Research Law, we may be required to refund certain grants previously received together with interest and penalties, and may
become subject to criminal charges.

Recent at-the-market sales of our ordinary shares may not have been made in compliance with all applicable securities laws, which could expose
us to potential liabilities, including potential rescission rights.

In  January  and  February  2021,  we  sold  approximately  $3.5  million  of  our  ordinary  shares  pursuant  to  our  existing  Equity  Distribution Agreement  with
Oppenheimer & Co., Inc. Those sales were made in an “at the market” offering as defined in Rule 415 promulgated under the Securities Act of 1933, as
amended, or the Securities Act, pursuant to our effective shelf registration statement on Form F-3 (File No. 333-251821). However, we inadvertently failed
to file a prospectus supplement specifying details regarding such sales. This may have constituted a violation of Section 5 of the Securities Act and may
give rise to liability under Section 12 of the Securities Act (which generally provides a rescission remedy for offers and sales of securities in violation of
Section 5) as well as potential liability under the anti-fraud provisions of federal and state securities laws and state rescission laws.

In such event, anyone who acquired such ordinary shares would have a right to rescind the purchase. If all the shareholders who acquired ordinary shares
demanded rescission, the maximum we would be obligated to repay would be approximately $3.5 million, plus interest. Out of the $3.5 million, there was
an identified buyer of $1.9 million. That buyer has agreed to waive his rescission right and signed a respective waiver. The Securities Act generally requires
that any claim brought for a violation of Section 5 of the Securities Act be brought within one year of the violation. Additionally, if it is determined that
such sales did in fact violate the Securities Act, we may become subject to fines and penalties imposed by the SEC and state securities agencies.

Risks Related to the Discovery and Development of Our Product Candidates

We have planned on the future success of our lead product candidate, VB-111, that missed the primary endpoints in the Phase 3 study in rGBM.
We continue to advance VB-111 for ovarian cancer and other indications. Any failure to successfully develop, obtain regulatory approval for and
commercialize VB-111 for cancer indications or any other product candidates, independently or in cooperation with a third party collaborator, or
the experience of significant delays in doing so, would compromise our ability to generate revenue and become profitable.

We  have  invested  a  significant  portion  of  our  efforts  and  financial  resources  in  the  development  of  VB-111  for  rGBM  and  VB-201  for  psoriasis  and
ulcerative colitis for which we have completed clinical trials in which they did not meet their primary endpoints. Our ability to generate product revenue
from our product candidates depends heavily on the successful development and commercialization of our product candidates, which, in turn, depends on
several factors, including the following:

●

●

●

our ability to continue and support the VTS platform technology and its lead candidate VB-111;

successfully completing our ongoing and future trials of VB-111 or other product candidates;

our ability to raise additional funding sufficient to conduct future clinical trials;

●

demonstrating that  VB-111  for  cancer  indications  or  other  product  candidates  is  safe  and  effective  at  a  sufficient  level  of  statistical  or  clinical
significance and otherwise obtaining marketing approvals from regulatory authorities;

operating our facility for the manufacture of commercial quantities of our product candidates, if approved;

manufacturing our product candidates in large scale and qualifying such processes in compliance with the regulatory requirements for clinical and
commercial supply;

establishing successful manufacturing arrangements with third-party manufacturers that are compliant with current good manufacturing practices,
or cGMP, and which will ensure the supply of our product candidates to the clinical development and commercial use, if approved;

establishing successful sales and marketing arrangements for our products, if approved;

maintaining an acceptable safety and efficacy profile for our products;

the availability of coverage and reimbursement to patients from healthcare payors for our products, if approved; and

other risks described in these “Risk Factors.”

Our product candidates are based on novel technologies, which makes it difficult to predict the time and cost of product candidate development
and potential regulatory approval.

We  have  concentrated  our  product  research  and  development  efforts  on  our  three  distinct  platform  technologies,  and  our  future  success  depends  on  the
successful  development  of  these  technologies.  We  could  experience  development  problems  in  the  future  related  to  our  technologies,  which  could  cause
significant  delays  or  unanticipated  costs,  and  we  may  not  be  able  to  solve  such  development  problems.  We  may  also  experience  delays  in  developing
sustainable, reproducible and scalable manufacturing processes or transferring those processes to commercial partners, if we decide to do so, which may
prevent us from completing our clinical trials or commercializing our products on a timely or profitable basis, if at all.

In addition, the clinical trial requirements of the FDA, the EMA and other regulatory agencies and the criteria these regulators use to determine the safety
and efficacy of a product candidate vary substantially according to the type, complexity, novelty and intended use and market of the potential products. The
regulatory approval process for novel product candidates such as ours can be more expensive and take longer than for other, better known or extensively
studied  pharmaceutical  or  other  product  candidates. Approvals  by  the  FDA  may  not  be  indicative  of  what  the  EMA  or  other  regulatory  agencies  may
require for approval, and vice versa.

Regulatory requirements governing pharmaceutical products have changed frequently and may continue to change in the future. Also, before a clinical trial
can  begin  at  an  institution  funded  by  the  U.S.  National  Institutes  of  Health,  or  the  NIH,  that  institution’s  institutional  review  board,  or  IRB,  and  its
Institutional  Biosafety  Committee  will  have  to  review  the  proposed  clinical  trial  to  assess  the  safety  of  the  trial.  In  addition,  adverse  developments  in
clinical trials of pharmaceutical products conducted by others may cause the FDA or other regulatory bodies to change the requirements for approval of any
of our product candidates.

These regulatory agencies and review committees and the new requirements and guidelines they promulgate may lengthen the regulatory review process,
require  us  to  perform  additional  studies,  increase  our  development  costs,  lead  to  changes  in  regulatory  positions  and  interpretations,  delay  or  prevent
approval and commercialization of these treatment candidates or lead to significant post-approval limitations or restrictions. As we advance our product
candidates, we will be required to consult with these regulatory groups, and comply with applicable requirements and guidelines. If we fail to do so, we
may be required to delay or discontinue development of our product candidates. Delay or failure to obtain, or unexpected costs in obtaining, the regulatory
approval necessary to bring a potential product candidate to market could impair our ability to generate product revenue and to become profitable.

We may find it difficult to enroll patients in our clinical trials, and patients could discontinue their participation in our clinical trials, which could
delay or prevent clinical trials of our product candidates.

Identifying  and  qualifying  patients  to  participate  in  clinical  trials  of  our  product  candidates  is  critical  to  our  success.  The  timing  of  our  clinical  trials
depends on the speed at which we can recruit patients to participate in testing our product candidates. We have experienced delays in some of our clinical
trials, and we may experience similar delays in the future. If patients are unwilling to participate in our clinical trials because of negative publicity from
adverse events in the biotechnology or pharmaceutical industries or for other reasons, including competitive clinical trials for similar patient populations,
the timeline for recruiting patients, conducting trials and obtaining regulatory approval of potential products may be delayed. These delays could result in
increased  costs,  delays  in  advancing  our  product  development,  delays  in  testing  the  effectiveness  of  our  technology  or  termination  of  the  clinical  trials
altogether.

We may not be able to identify, recruit and enroll a sufficient number of patients, or those with required or desired characteristics to achieve diversity in a
trial, to complete our clinical trials in a timely manner. Patient enrollment is affected by factors including:

●

●

●

●

●

●

●

●

●

●

severity of the disease under investigation;

design of the trial protocol;

size of the patient population;

eligibility criteria for the trial in question;

perceived  risks  and  benefits  of  the  product  candidate  under  study,  and  specifically  in  reference  to  studies  in  other  indications,  with  the  same
product;

proximity and availability of clinical trial sites for prospective patients;

availability of competing therapies and clinical trials;

efforts to facilitate timely enrollment in clinical trials;

patient referral practices of physicians; and

ability to monitor patients adequately during and after treatment.

In  particular,  VB-111  for  ovarian  cancer  is  intended  for  a  rare  disorder  with  limited  patient  pools  from  which  to  draw  for  clinical  trials.  The  eligibility
criteria of our clinical trials will further limit the pool of available trial participants. Additionally, the process of finding and diagnosing patients may prove
costly.

Additionally, timely enrollment in clinical trials is reliant on clinical trial sites which may be adversely affected by global health matters, including, among
other  things  pandemics.  For  example,  in  December  2019,  an  outbreak  of  a  novel  strain  of  coronavirus,  or  the  SARS-CoV-2  coronavirus,  which  causes
COVID-19,  had  ripple  effects  to  businesses  around  the  world,  negatively  impacted  activity  and  operations,  including  extended  shutdowns  of  certain
businesses, in many countries, including the USA, European countries and Israel, where our operations are. The list of countries and regions affected by the
coronavirus outbreak is constantly changing and our clinical trial sites may be located in regions currently being afflicted by the COVID-19 pandemic.
Some factors from the coronavirus outbreak that we believe may adversely affect enrollment in our trials include:

● the diversion  of  healthcare  resources  away  from  the  conduct  of  clinical  trial  matters  to  focus  on  pandemic  concerns,  including  the  attention  of
infectious disease physicians serving as our clinical trial investigators, hospitals serving as our clinical trial sites and hospital staff supporting the
conduct of our clinical trials;

● limitations on travel that interrupt key trial activities, such as clinical trial site initiations and monitoring;

● interruption in global shipping affecting the transport of clinical trial materials, such as investigational drug product and comparator drugs used in

our trials; and

● employee furlough days that delay necessary interactions with local regulators, ethics committees and other important agencies and contractors.

These and other factors arising from the COVID-19 pandemic could worsen in countries that are already afflicted with the virus or could continue to spread
to additional countries, each of which may further adversely impact our clinical trials. The global outbreak of the SARS-CoV-2 coronavirus continues to
evolve and the conduct of our trials may continue to be adversely affected, despite efforts to mitigate this impact.

For more information on the extent that the COVID-19 pandemic has impacted our development programs to date, please refer to the related section in the
Overview part.

The  COVID-19  pandemic  could  also  interrupt  the  business  of  our  subcontractors,  vendors  and  external  laboratories,  in  ways  and  to  an  extent,  that  we
cannot foresee yet.

We plan to seek initial marketing approval in Europe in addition to the United States. We may not be able to initiate or continue clinical trials if we cannot
enroll a sufficient number of eligible patients to participate in the clinical trials required by the EMA or other foreign regulatory agencies. Our ability to
successfully  initiate,  enroll  and  complete  a  clinical  trial  in  any  foreign  country  is  subject  to  numerous  risks  unique  to  conducting  business  in  foreign
countries, including:

●

●

●

●

difficulty in establishing or managing relationships with contract research organizations, or CROs, and physicians;

different standards for the conduct of clinical trials;

our inability to locate qualified local consultants, physicians and partners; and

the  potential  burden  of  complying  with  a  variety  of  foreign  laws,  medical  standards  and  regulatory  requirements,  including  the  regulation  of
pharmaceutical and biotechnology products and treatment.

If we have difficulty enrolling a sufficient number of patients to conduct our clinical trials as planned, we may need to delay, limit or terminate ongoing or
planned clinical trials.

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
In addition, patients enrolled in our clinical trials may discontinue their participation at any time during the trial as a result of a number of factors, including
withdrawing their consent or experiencing adverse clinical events, which may or may not be judged related to our product candidates under evaluation. The
discontinuation of patients in any one of our trials may cause us to delay or abandon our clinical trial, or cause the results from that trial not to be positive
or sufficient to support a filing for regulatory approval of the applicable product candidate.

We  may  encounter  substantial  delays  in  our  clinical  trials  or  we  may  fail  to  demonstrate  safety  and  efficacy  to  the  satisfaction  of  applicable
regulatory authorities.

We are currently in Phase 3 clinical trial for VB-111 for ovarian cancer and expect to support two Sponsor-Investigator trials, one for rGBM and the other
for GI tumors in combination with an immune-oncology drug. Before obtaining marketing approval from regulatory authorities for the sale of our product
candidates,  we  must  conduct  extensive  clinical  trials  to  demonstrate  the  safety  and  efficacy  of  the  product  candidates  in  humans.  Clinical  testing  is
expensive,  time-consuming  and  uncertain  as  to  outcome.  We  cannot  guarantee  that  any  clinical  trials  will  be  conducted  as  planned  or  completed  on
schedule, if at all. A failure of one or more clinical trials can occur at any stage of testing. Events that may prevent successful or timely completion of
clinical development include:

●

●

●

●

●

●

●

●

●

●

●

●

●

delays in reaching a consensus with regulatory agencies on trial design;

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

delays in obtaining required IRB or ethics committee approval at each clinical trial site;

delays in  recruiting  suitable  patients  to  participate  in  our  clinical  trials  including  in  particular  for  those  trials  for  rare  diseases  such  as  ovarian
cancer;

imposition of a clinical hold by regulatory agencies, including due to safety reasons with either our product candidate or other product candidates in
the same class or after an inspection of our clinical trial operations or trial sites;

failure by our CROs, other third parties or us to adhere to clinical trial requirements;

failure to perform in accordance with the FDA’s good clinical practices, or GCP, or applicable regulatory requirements in other countries;

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

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

clinical trial sites or patients dropping out of a trial;

occurrence of serious adverse events associated with the product candidate that are viewed to outweigh its potential benefits;

changes in regulatory requirements and guidance that require amending or submitting new clinical trial protocols; or

discontinuation or other hurdles in the expected Sponsor-Investigator trials, which are conducted by academic and other investigational third parties
and are not controlled by us.

Any inability to successfully complete preclinical and clinical development could result in additional costs to us or impair our ability to generate revenue
from product sales. In addition, if we make manufacturing or formulation changes to our product candidates, we may need to conduct additional studies to
bridge our modified product candidates to earlier versions. Clinical trial delays could also shorten any periods during which we may have the exclusive
right  to  commercialize  our  product  candidates  or  allow  our  competitors  to  bring  products  to  market  before  we  do,  which  could  impair  our  ability  to
successfully commercialize our product candidates.

If the results of our clinical trials are inconclusive or if there are safety concerns or adverse events associated with our product candidates, we may:

●

●

●

●

●

●

●

●

●

fail to obtain, or be delayed in obtaining, marketing approval for our product candidates;

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

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

need to change the way the product is administered;

be required to perform additional clinical trials to support approval or be subject to additional post-marketing testing requirements;

have regulatory authorities withdraw their approval of the product or impose restrictions on  its  distribution  in  the  form  of  a  risk  evaluation  and
mitigation strategy, or REMS, or modified REMS;

be subject to the addition of labeling statements, such as warnings or contraindications;

be sued; or

experience damage to our reputation.

Any of these events could prevent us from achieving or maintaining market acceptance of our product candidates and impair our ability to commercialize
our product candidates.

Side effects may occur following treatment with our product candidates, which could make it more difficult for our product candidates to receive
regulatory approval.

Treatment with our product candidates may cause side effects or adverse events. In addition, since our product candidates are in some cases administered in
combination with other therapies, patients or clinical trial participants may experience side effects or other adverse events that are unrelated to our product
candidate, but may still impact the success of our clinical trials. Additionally, our product candidates could potentially cause other adverse events that have
not yet been predicted. The inclusion of critically ill patients in our clinical trials may result in deaths or other adverse medical events due to other therapies
or medications that such patients may be using or the severity of the medical condition treated. The experience of side effects and adverse events in our
clinical trials could make it more difficult to achieve regulatory approval of our product candidates or, if approved, could negatively impact the market
acceptance of such products.

Success in early and prior clinical trials may not be indicative of results obtained in later trials.

There is a high failure rate for drugs and biologics proceeding through clinical trials. A number of companies in the pharmaceutical and biotechnology
industries have suffered significant setbacks in later stage clinical trials even after achieving promising results in earlier stage and prior clinical trials. Data
obtained from preclinical and clinical activities are subject to varying interpretations, which may delay, limit or prevent regulatory approval. In addition,
regulatory  delays  or  rejections  may  be  encountered  as  a  result  of  many  factors,  including  changes  in  regulatory  policy  during  the  period  of  product
development.

The results from our clinical trials may not be sufficiently robust to support the submission for marketing approval for our product candidates.
Before we submit our product candidates for marketing approval, the FDA and the EMA may require us to conduct additional clinical trials, or
evaluate subjects for an additional follow-up period.

It is possible that, even if we achieve favorable results in our clinical trials, the FDA may require us to conduct additional clinical trials, possibly involving
a larger sample size or a different clinical trial design, particularly if the FDA does not find the results from our completed clinical trials to be sufficiently
persuasive to support a Biologics License Application, or BLA, or a New Drug Application, or NDA. For example, because the dose we used in our Phase
2 trial was limited by our production capacity, the dose of VB-111 that we intend to use in our Phase 3 registration enabling trial may not be the maximum
efficacious dose. The FDA might require data on higher doses of VB-111, this will likely delay development. The FDA may also require that we conduct a
longer follow-up period of subjects treated with our product candidates prior to accepting our BLA or NDA.

It is possible that the FDA or the EMA may not consider the results of our clinical trials to be sufficient for approval of our product candidates for their
target indications. If the FDA or the EMA requires additional studies for any reason, we would incur increased costs and delays in the marketing approval
process, which may require us to expend more resources than we have available. In addition, it is possible that the FDA and the EMA may have divergent
opinions  on  the  elements  necessary  for  a  successful  BLA  or  NDA  and  Marketing  Authorization  Application,  which  is  the  equivalent  of  a  BLA,
respectively, which may cause us to alter our development, regulatory or commercialization strategies.

Even  if  we  complete  the  necessary  preclinical  studies  and  clinical  trials,  we  cannot  predict  when  or  if  we  will  obtain  regulatory  approval  to
commercialize a product candidate or the approval may be for a more narrow indication than we expect.

We cannot commercialize a product until the appropriate regulatory authorities have reviewed and approved the product candidate. Even if our product
candidates demonstrate safety and efficacy in clinical trials, the regulatory agencies may not complete their review processes in a timely manner, or we may
not be able to obtain regulatory approval. Additional delays may result if an FDA Advisory Committee or other regulatory authority recommends non-
approval  or  restrictions  on  approval.  In  addition,  we  may  experience  delays  or  rejections  based  upon  additional  government  regulation  from  future
legislation or administrative action, or changes in regulatory agency policy during the period of product development, clinical trials and the review process.
Regulatory  agencies  also  may  approve  a  treatment  candidate  for  fewer  or  more  limited  indications  than  requested  or  may  grant  approval  subject  to  the
performance  of  post-marketing  studies.  In  addition,  regulatory  agencies  may  not  approve  the  labeling  claims  that  are  necessary  or  desirable  for  the
successful commercialization of our treatment candidates.

A fast track designation by the FDA may not actually lead to a faster development or regulatory review or approval process.

If a drug is intended for the treatment of a serious or life-threatening disease or condition and the drug demonstrates the potential to address unmet medical
needs for this disease or condition, the drug sponsor may apply for FDA fast track designation. If fast track designation is obtained, the FDA may initiate
review  of  sections  of  an  NDA  or  BLA,  before  the  application  is  complete.  This  “rolling  review”  is  available  if  the  applicant  provides,  and  the  FDA
approves, a schedule for submission of the individual sections of the application.

We have received fast track designation from the FDA for VB-111 for prolongation of survival in patients with glioblastoma that has recurred following
treatment  with  temozolomide,  a  chemotherapeutic  agent  commonly  used  to  treat  newly  diagnosed  glioblastoma,  and  radiation.  We  may  seek  fast  track
designation  for  other  product  candidates  and  other  indications.  Even  though  we  have  received  fast  track  designation,  we  may  not  experience  a  faster
development process, review or approval compared to conventional FDA procedures. The FDA may withdraw fast track designation if it believes that the
designation is no longer supported by data from our clinical development program. Our fast track designation does not guarantee that we will qualify for or
be able to take advantage of the expedited review procedures or that we will ultimately obtain regulatory approval of VB-111.

Even though we have obtained orphan drug designation for VB-111 for treatment of malignant glioma in the United States and glioma in Europe,
and for the treatment of ovarian cancer in Europe, we may not be able to obtain orphan drug exclusivity for this drug or for any of our other
product candidates.

Regulatory authorities in some jurisdictions, including the United States and Europe, may designate drugs for relatively small patient populations as orphan
drugs. Under the Orphan Drug Act, the FDA may designate a product as an orphan drug if it is a drug intended to treat a rare disease or condition, which is
generally  defined  as  a  patient  population  of  fewer  than  200,000  individuals  annually  in  the  United  States.  For  VB-111,  we  have  obtained  orphan  drug
designation from the FDA for the treatment of malignant glioma and the European Commission for the treatment of glioma and ovarian cancer, and we
may seek orphan drug designation for other drug candidates.

Generally,  if  a  product  with  an  orphan  drug  designation  subsequently  receives  the  first  marketing  approval  for  the  indication  for  which  it  has  such
designation,  the  product  is  entitled  to  a  period  of  marketing  exclusivity,  which  precludes  the  EMA  or  the  FDA  from  approving  another  marketing
application for the same drug for the same use or indication for that time period. The applicable period is seven years in the United States and ten years in
Europe. The European exclusivity period can be reduced to six years if a drug no longer meets the criteria for orphan drug designation or if the drug is
sufficiently profitable so that market exclusivity is no longer justified. Orphan drug exclusivity may be lost if the FDA or EMA determines that the request
for designation was materially defective or if the manufacturer is unable to assure sufficient quantity of the drug to meet the needs of patients with the rare
disease or condition.

Even if we obtain orphan drug exclusivity for a product, that exclusivity may not effectively protect the product from competition because different drugs
can be approved for the same condition. Even after an orphan drug is approved, the FDA can subsequently approve the same drug for the same condition if
the FDA concludes that the later drug is clinically superior in that it is shown to be safer, more effective or makes a major contribution to patient care.

Even if we obtain regulatory approval for a product candidate, our products will remain subject to regulatory scrutiny.

Even if we obtain regulatory approval in a jurisdiction, the regulatory authority may still impose significant restrictions on the indicated uses or marketing
of our product candidates, or impose ongoing requirements for potentially costly post-approval studies or post-market surveillance. For example, the holder
of an approved BLA is obligated to monitor and report adverse events and any failure of a product to meet the specifications in the BLA. The holder of an
approved BLA must also submit new or supplemental applications and obtain FDA approval for certain changes to the approved product, product labeling
or  manufacturing  process.  Advertising  and  promotional  materials  must  comply  with  FDA  rules  and  are  subject  to  FDA  review,  in  addition  to  other
potentially applicable federal and state laws.

In addition, product manufacturers and their facilities are subject to payment of user fees and continual review and periodic inspections by the FDA and
other regulatory authorities for compliance with cGMP, and adherence to commitments made in the BLA or NDA as the case may be. 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 relative to that product or the manufacturing facility, including requiring
recall or withdrawal of the product from the market or suspension of manufacturing.

If we fail to comply with applicable regulatory requirements following approval of any of our product candidates, a regulatory agency may:

●

●

●

●

●

●

●

issue a warning letter asserting that we are in violation of the law;

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

suspend or withdraw regulatory approval or suspend or revoke a license;

suspend any ongoing clinical trials;

refuse to approve a pending BLA or NDA or supplements to a BLA or NDA submitted by us for other indications or new drug products;

seize our product; or

refuse 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  time  and  resources  in  response  and  could  generate
negative publicity. The occurrence of any event or penalty described above may inhibit our ability to commercialize our product candidates and generate
revenues.

We have only limited experience in regulatory affairs and intend to rely on consultants and other third parties for regulatory matters, which may
affect our ability or the time we require to obtain necessary regulatory approvals.

We have limited experience in filing and prosecuting the applications necessary to gain regulatory approvals for drug and biologics candidates. Moreover,
the  product  candidates  that  are  likely  to  result  from  our  development  programs  are  based  on  new  technologies  that  have  not  been  extensively  tested  in
humans.  The  regulatory  requirements  governing  these  types  of  product  candidates  may  be  less  well  defined  or  more  rigorous  than  for  conventional
products. As a result, we may experience a longer regulatory process in connection with obtaining regulatory approvals of any products that we develop.
We intend to rely on independent consultants for purposes of our regulatory compliance and product development and approvals in the United States and
elsewhere. Any failure by our consultants to properly advise us regarding, or properly perform tasks related to, regulatory compliance requirements could
compromise our ability to develop and seek regulatory approval of our product candidates.

In addition to the level of commercial success of our product candidates, if approved, our future prospects are also dependent on our ability to
successfully develop a pipeline of additional product candidates, and we may not be successful in our efforts in using our platform technologies to
identify or discover additional product candidates.

The success of our business depends primarily upon our ability to identify, develop and commercialize products based on our three platform technologies.
Our research programs may fail to identify other potential product candidates for clinical development for a number of reasons. Our research methodology
may be unsuccessful in identifying potential product candidates or our potential product candidates may be shown to have harmful side effects or may have
other characteristics that may make the products unmarketable or unlikely to receive marketing approval.

If any of these events occur, we may be forced to abandon our development efforts for a program or programs. Research programs to identify new product
candidates  require  substantial  technical,  financial  and  human  resources.  We  may  focus  our  efforts  and  resources  on  potential  programs  or  product
candidates that ultimately prove to be unsuccessful.

Risks Related to Our Reliance on Third Parties

We expect to rely on third parties to conduct some or all aspects of our product manufacturing, protocol development, research and preclinical
and clinical testing, and these third parties may not perform satisfactorily.

We do not expect to independently conduct all aspects of our product manufacturing, protocol development, research and preclinical and clinical testing.
We currently rely, and expect to continue to rely, on third parties with respect to these items. In addition, we may pursue further clinical development of
VB-111 for thyroid cancer or other indications with a strategic partner.

Any of these third parties may terminate their engagements with us at any time. If we need to enter into alternative arrangements, it could delay our product
development activities. Our reliance on these third parties for research and development activities will reduce our control over these activities but will not
relieve us of our responsibility to ensure compliance with all required regulations and study protocols. For example, for product candidates that we develop
and commercialize on our own, we will remain responsible for ensuring that each of our Investigational New Drug, or IND, enabling studies and clinical
trials are conducted in accordance with the study plan and protocols.

If these third parties do not successfully carry out their contractual duties, meet expected deadlines or conduct our studies in accordance with regulatory
requirements or our stated study plans and protocols, we will not be able to complete, or may be delayed in completing, the preclinical studies and clinical
trials required to support future IND submissions and approval of our product candidates.

Reliance on third-party manufacturers entails risks to which we would not be subject if we manufactured the product candidates ourselves, including:

●

●

●

●

the inability to negotiate manufacturing agreements with third parties under commercially reasonable terms;

reduced control as a result of using third-party manufacturers for all aspects of manufacturing activities;

termination or nonrenewal of manufacturing agreements with third parties in a manner or at a time that is costly or damaging to us; and

disruptions to the operations of our third-party manufacturers or suppliers caused by conditions unrelated to our business or operations, including
the bankruptcy of the manufacturer or supplier.

Any of these events could lead to clinical trial delays or failure to obtain regulatory approval, or impact our ability to successfully commercialize future
products. Some of these events could be the basis for FDA action, including injunction, recall, seizure or total or partial suspension of production.

We  and  our  contract  manufacturers  are  subject  to  significant  regulation  with  respect  to  manufacturing  our  product  candidates.  The
manufacturing facilities on which we rely may not continue to meet regulatory requirements and have limited capacity.

We currently have relationships with a limited number of suppliers for the manufacturing of our product candidates. Each supplier may require licenses to
manufacture components of our product candidates or to utilize certain processes for the manufacture of our product candidates. If such components or
licenses are not owned by the supplier or in the public domain, we may be unable to transfer or sublicense the intellectual property rights we may have with
respect to such activities.

All entities involved in the preparation of therapeutics for clinical trials or commercial sale, including our existing contract manufacturers for our product
candidates, are subject to extensive regulation. Components of a finished therapeutic product approved for commercial sale or used in late-stage clinical
trials must be manufactured in accordance with cGMP. These regulations govern manufacturing processes and procedures (including record keeping) and
the implementation and operation of systems to control and assure the quality of investigational products and products approved for sale. Poor control of
production processes can lead to the introduction of contaminants, or to inadvertent changes in the properties or stability of our product candidates that may
not  be  detectable  in  final  product  testing.  We  or  our  contract  manufacturers  must  supply  all  necessary  documentation  in  support  of  a  BLA  or  NDA,  as
applicable, on a timely basis and must adhere to the FDA’s good laboratory practices, or GLP, and cGMP regulations enforced by the FDA through its
facilities inspection program. We and our contract manufacturer for VB-111 have not produced a commercially approved product based on viral vectors
and therefore have not yet obtained the requisite FDA approvals to do so. Our facilities and controls and the facilities and controls of some or all of our
third-party  contractors  must  pass  a  pre-approval  inspection  for  compliance  with  the  applicable  regulations  as  a  condition  of  regulatory  approval  of  our
product candidates or any of our other potential products. In addition, the regulatory authorities may, at any time, audit or inspect a manufacturing facility
involved  with  the  preparation  of  our  product  candidates  or  our  other  potential  products  or  the  associated  controls  for  compliance  with  the  regulations
applicable to the activities being conducted. If these facilities do not pass a pre-approval plant inspection, FDA or other regulatory authority approval of the
products will not be granted.

The  regulatory  authorities  also  may,  at  any  time  following  approval  of  a  product  for  sale,  audit  our  manufacturing  facilities  or  those  of  our  third-party
contractors.  If  any  such  inspection  or  audit  identifies  a  failure  to  comply  with  applicable  regulations  or  our  product  specifications,  or  if  a  violation  of
applicable regulations, including a failure to comply with the product specifications, occurs independent of such an inspection or audit, we or the relevant
regulatory authority may require remedial measures that may be costly and/or time-consuming for us or a third party to implement and that may include the
temporary or permanent suspension of a clinical trial or commercial sales or the temporary or permanent closure of a facility.

If  we  or  any  of  our  third-party  manufacturers  fail  to  maintain  regulatory  compliance,  the  FDA  can  impose  regulatory  sanctions  including,  among  other
things, refusal to approve a pending application for a new drug product or biologic product, or revocation of a pre-existing approval.

Additionally,  if  supply  from  one  approved  manufacturer  is  interrupted,  there  could  be  a  significant  disruption  in  commercial  supply.  An  alternative
manufacturer would need to be qualified through a BLA or NDA supplement which could result in further delay. The regulatory agencies may also require
additional studies if a new manufacturer is relied upon for commercial production. Switching manufacturers may involve substantial costs and is likely to
result in a delay in our desired clinical and commercial timelines.

These factors could cause the delay of clinical trials, regulatory submissions, required approvals or commercialization of our product candidates, cause us
to incur higher costs and prevent us from commercializing our products successfully. Furthermore, if our suppliers fail to meet contractual requirements,
and we are unable to secure one or more replacement suppliers capable of production at a substantially equivalent cost, our clinical trials may be delayed or
we could lose potential revenue.

We  expect  to  rely  on  third  parties  to  conduct,  supervise  and  monitor  our  clinical  trials,  and  if  these  third  parties  perform  in  an  unsatisfactory
manner, it may harm our business.

We expect to rely on CROs and clinical trial sites, including clinical investigators, to ensure our clinical trials are conducted properly and on time. While
we will have agreements governing their activities, we will have limited influence over their actual performance. We will control only some aspects of our
CROs’ activities. Nevertheless, we will be responsible for ensuring that each of our clinical trials is conducted in accordance with the applicable protocol,
legal, regulatory and scientific requirements and standards, and our reliance on the CROs does not relieve us of our regulatory responsibilities.

We and our CROs are required to comply with the FDA’s GCPs for conducting, recording and reporting the results of clinical trials to assure that the data
and reported results are credible and accurate and that the rights, integrity and confidentiality of clinical trial participants are protected. The FDA enforces
these GCPs through periodic inspections of study sponsors, principal investigators and clinical trial sites. If we or our CROs fail to comply with applicable
GCPs, the clinical data generated in our clinical trials may be deemed unreliable and the FDA may require us to perform additional clinical trials before
approving any marketing applications. Upon inspection, the FDA may determine that our clinical trials did not comply with GCPs. In addition, our clinical
trials will require a sufficient number of test subjects to evaluate the safety and effectiveness of our product candidates. Recruitment may be challenging in
the event of rare diseases and may require the performance of trials in a significant number of sites which may be harder to monitor. Accordingly, if our
CROs fail to comply with these regulations or fail to recruit a sufficient number of patients, we may be required to repeat such clinical trials, which would
delay the regulatory approval process.

16

 
 
 
 
 
 
 
 
 
 
 
 
 
Table of Contents

Our CROs are not our employees, and we are therefore unable to directly monitor whether or not they devote sufficient time and resources to our clinical
and nonclinical programs. These CROs may also have relationships with other commercial entities, including parties developing potentially competitive
products, for whom they may also be conducting clinical trials or other drug development activities that could harm our competitive position. If our CROs
do not successfully carry out their contractual duties or obligations, fail to meet expected deadlines, or if the quality or accuracy of the clinical data they
obtain is compromised due to the failure to adhere to our clinical protocols or regulatory requirements, or for any other reason, our clinical trials may be
extended, delayed or terminated, and we may not be able to obtain regulatory approval for, or successfully commercialize our product candidates. As a
result,  the  commercial  prospects  for  our  product  candidates  would  be  harmed,  our  costs  could  increase,  and  our  ability  to  generate  revenues  could  be
delayed.

We also expect to rely on other third parties to store and distribute our product candidates for any clinical trials that we may conduct. Any performance
failure on the part of our distributors could delay clinical development or marketing approval of our product candidates or commercialization of our product
candidates, if approved, producing additional losses and depriving us of potential product revenue.

Our reliance on third parties requires us to share our trade secrets, which increases the possibility that a competitor will discover them or that our
trade secrets will be misappropriated or disclosed.

Because we rely on third parties to manufacture our product candidates, and because we collaborate with various organizations and academic institutions
on the advancement of our technology, we must, at times, share trade secrets with them. We seek to protect our proprietary technology in part by entering
into confidentiality agreements and, if applicable, material transfer agreements, collaborative research agreements, consulting agreements or other similar
agreements  with  our  collaborators,  advisors,  employees  and  consultants  prior  to  beginning  research  or  disclosing  proprietary  information.  These
agreements  typically  limit  the  rights  of  the  third  parties  to  use  or  disclose  our  confidential  information,  such  as  trade  secrets.  Despite  these  contractual
provisions,  the  need  to  share  trade  secrets  and  other  confidential  information  increases  the  risk  that  such  trade  secrets  become  known  by  potential
competitors,  are  inadvertently  incorporated  into  the  technology  of  others,  or  are  disclosed  or  used  in  violation  of  these  agreements.  Given  that  our
proprietary  position  is  based,  in  part,  on  our  know-how  and  trade  secrets,  discovery  by  a  third  party  of  our  trade  secrets  or  other  unauthorized  use  or
disclosure would impair our intellectual property rights and protections in our product candidates.

In addition, these agreements typically restrict the ability of our collaborators, advisors, employees and consultants to publish data potentially relating to
our trade secrets. Our academic collaborators typically have rights to publish data, provided that we are notified in advance and may delay publication for a
specified time in order to secure our intellectual property rights arising from the collaboration. In other cases, publication rights are controlled exclusively
by us, although in some cases we may share these rights with other parties. Despite our efforts to protect our trade secrets, our competitors may discover
our trade secrets, either through breach of these agreements, independent development or publication of information including our trade secrets in cases
where we do not have proprietary or otherwise protected rights at the time of publication.

Risks Related to Commercialization of Our Product Candidates

We  intend  to  fully  rely  or  partially  rely  on  third-party  manufacturers  to  produce  commercial  quantities  of  any  of  our  product  candidates  that
receives  regulatory  approval,  but  we  have  not  entered  into  binding  agreements  with  any  such  manufacturers  to  support  commercialization.
Additionally, these manufacturers do not have experience producing our product candidates at commercial levels and may not pass regulatory
inspections  or  achieve  the  necessary  regulatory  approvals  or  produce  our  product  candidates  at  the  quality,  quantities,  locations  and  timing
needed to support commercialization.

We have not yet secured manufacturing capabilities for commercial quantities of our product candidates to support world-wide commercialization of our
product candidates. Although we intend to partially rely on third-party manufacturers for commercialization, we have only entered into agreements with
such  manufacturers  to  assist  in  the  scaling  up  of  the  manufacturing  process  of  VB-111.  We  may  be  unable  to  negotiate  binding  agreements  with  the
manufacturers to support our commercialization activities on commercially reasonable terms, which agreements will further be required to comply with the
restrictions imposed under the Research Law.

We  may  encounter  technical  or  scientific  issues  related  to  manufacturing  or  development  that  we  may  be  unable  to  resolve  in  a  timely  manner  or  with
available  funds.  Although  we  have  established  a  site  in  which  we  are  planning  to  apply  a  commercial  scale  manufacturing,  the  available  capacity  to
manufacture our product candidates on a commercial scale is still limited. In addition, our product candidates are novel, and no manufacturer currently has
the experience or ability to produce our product candidates at commercial levels. If we are unable to produce or engage manufacturing partners to produce
our product candidates on a larger scale on reasonable terms, our commercialization efforts will be harmed.

17

 
 
 
 
 
 
 
 
 
 
 
 
Table of Contents

Even  if  we  timely  complete  the  development  of  a  manufacturing  process  and  successfully  transfer  it  to  the  third-  party  manufacturers  of  our  product
candidates, if we or such third-party manufacturers are unable to produce the necessary quantities of our product candidates, or in compliance with cGMP
or with pertinent regulatory requirements, and within our planned time frame and cost parameters, the development and sales of our product candidates, if
approved, may be impaired.

In  addition,  any  significant  disruption  in  our  supplier  relationships  could  harm  our  business.  We  source  key  materials  from  third  parties,  either  directly
through agreements with suppliers or indirectly through our manufacturers who have agreements with suppliers. There are a small number of suppliers, and
in  some  cases  a  single  supplier  for  certain  key  materials  that  are  used  to  manufacture  our  product  candidates.  Such  suppliers  may  not  sell  these  key
materials to our manufacturers at the times we need them or on commercially reasonable terms. We do not have any control over the process or timing of
the acquisition of these key materials by our manufacturers. Moreover, we currently do not have any agreements for the commercial production of these
key materials.

If we are unable to establish sales and marketing capabilities or enter into agreements with third parties to market and sell any of our product
candidates that obtain regulatory approval, we may be unable to generate any revenue.

We have no experience selling and marketing our product candidates or any other products. To successfully commercialize any products that may result
from our development programs and obtain regulatory approval, we will need to develop these capabilities, either on our own or with others. We may seek
to enter into collaborations with other entities to utilize their marketing and distribution capabilities, but we may be unable to do so on favorable terms, if at
all. If any future collaborative partners do not commit sufficient resources to commercialize our future products, if any, and we are unable to develop the
necessary marketing capabilities on our own, we will be unable to generate sufficient product revenue to sustain our business. We will be competing with
many companies that currently have extensive and well-funded marketing and sales operations. Without sufficient internal capability or the support of a
third party to perform marketing and sales functions, we may be unable to compete successfully against these more established companies or successfully
commercialize any of our product candidates.

We  face  intense  competition  and  rapid  technological  change  and  the  possibility  that  our  competitors  may  develop  therapies  that  are  more
advanced or effective than ours, which could impair our ability to successfully commercialize our product candidates.

We  are  engaged  in  pharmaceutical  development,  which  is  a  rapidly  changing  field.  We  have  competitors  both  in  the  United  States  and  internationally,
including major multinational pharmaceutical companies, biotechnology companies and universities and other research institutions.

Many of our potential competitors have substantially greater financial, technical and other resources, such as larger research and development staff and
experienced  marketing  and  manufacturing  organizations.  Competition  may  increase  further  as  a  result  of  advances  in  the  commercial  applicability  of
technologies  and  greater  availability  of  capital  for  investment  in  these  industries.  Our  potential  competitors  may  succeed  in  developing,  acquiring  or
licensing on an exclusive basis, products that are more effective or less costly than any product candidate that we may develop, or achieve earlier patent
protection, regulatory approval, product commercialization and market penetration than us. Additionally, technologies developed by others may render our
potential product candidates uneconomical or obsolete, and we may not be successful in marketing our product candidates against competitors.

In particular, VB-111 may face competition from currently approved drugs and drug candidates under development by others to treat rGBM or ovarian
cancer. In May 2009, the FDA granted accelerated approval to bevacizumab (Avastin®), which is an angiogenesis inhibitor, to treat patients with rGBM at
progression  after  standard  first-line  therapy.  Bevacizumab  also  received  FDA  approval  for  platinum-resistant  ovarian  cancer  in  2014,  and  for  newly
diagnosed patients after their initial surgery in 2018. In addition to bevacizumab, a number of companies are conducting late-stage clinical trials to test
targeted  drugs  focused  on  angiogenesis  inhibition  for  the  treatment  of  ovarian  cancer,  including,  among  others,  Amgen’s  trebananib,  Boehringer
Ingelheim’s nintedanib, AstraZeneca’s cediranib, Novartis’s Votrient, HengRui Medicine’s apatinib and Mereo BioPharma’s navicixizumab. The expansion
of PARP inhibitors (such as olaparib, niraparib and veliparib) for ovarian cancer, and clinical studies evaluating the potential use of checkpoint inhibitors,
antibody-drug conjugates, bispecific Abs, GAS6/AXL inhibitors, WEE1 inhibitors, CDK4/6 inhibitors or Tumor Treating Fields medical device for ovarian
cancer may also affect the prior lines of therapy, or the segment of patient population who will seek treatment with VB-111.

Even if we are successful in achieving regulatory approval to commercialize a product candidate faster than our competitors, we may face competition
from biosimilars. In the United States, the Biologics Price Competition and Innovation Act of 2009 created an abbreviated approval pathway for biological
products that are demonstrated to be “highly similar,” or biosimilar, to or “interchangeable” with an FDA-approved biological product. This pathway could
allow  competitors  to  reference  data  from  biological  products  already  approved  after  12  years  from  the  time  of  approval.  In  Europe,  the  European
Commission has granted marketing authorizations for several biosimilars pursuant to a set of general and product class-specific guidelines for biosimilar
approvals issued over the past few years. In Europe, a competitor may reference data from biological products already approved, but will not be able to
market a biosimilar until ten years after the time of approval. This 10-year period will be extended to 11 years if, during the first eight of those 10 years, the
marketing  authorization  holder  obtains  an  approval  for  one  or  more  new  therapeutic  indications  that  bring  significant  clinical  benefits  compared  with
existing therapies. In addition, companies may be developing biosimilars in other countries that could compete with our products. If competitors are able to
obtain  marketing  approval  for  biosimilars  referencing  our  products,  our  products  may  become  subject  to  competition  from  such  biosimilars,  with  the
attendant competitive pressure and consequences. Expiration or successful challenge of our applicable patent rights could also trigger competition from
other products, assuming any relevant exclusivity period has expired.

18

 
 
 
 
 
 
 
 
 
 
 
 
Table of Contents

In addition, although VB-111 has been granted orphan drug status by the FDA and EMA for a specified indication, there are limitations to the exclusivity.
In  the  United  States,  the  exclusivity  period  for  orphan  drugs  is  seven  years,  while  pediatric  exclusivity  adds  six  months  to  any  existing  patents  or
exclusivity periods. In Europe, orphan drugs may be able to obtain 10 years of marketing exclusivity and up to an additional two years on the basis of
qualifying  pediatric  studies.  However,  orphan  exclusivity  may  be  reduced  to  six  years  if  the  drug  no  longer  satisfies  the  original  designation  criteria.
Additionally, a marketing authorization holder may lose its orphan exclusivity if it consents to a second orphan drug application or cannot supply enough
drug. Orphan drug exclusivity also can be lost when a second applicant demonstrates its drug is “clinically superior” to the original orphan drug.

Finally,  as  a  result  of  the  expiration  or  successful  challenge  of  our  patent  rights,  we  could  face  more  litigation  with  respect  to  the  validity  or  scope  of
patents relating to other parties’ products. The availability of other parties’ products could limit the demand, and the price we are able to charge, for any
products that we may develop and commercialize.

Since some of our product candidates are aimed for rare diseases, loss of exclusivity or competition as described above may be very significant in light of
the limited size of the relevant market.

The commercial success of any current or future product candidate, if approved, will depend upon the degree of market acceptance by physicians,
patients, third-party payors and others in the medical community.

Even  if  we  obtain  the  requisite  regulatory  approvals,  the  commercial  success  of  our  product  candidates  will  depend  in  part  on  the  medical  community,
patients, and third-party payors accepting our product candidates as medically useful, cost-effective, and safe. Any product that we bring to the market may
not gain market acceptance by physicians, patients, third-party payors and others in the medical community. If these products do not achieve an adequate
level of acceptance, we may not generate significant product revenue and may not become profitable. The degree of market acceptance of these product
candidates, if approved for commercial sale, will depend on a number of factors, including:

●

●

●

●

●

●

●

●

the potential efficacy and potential advantages over alternative treatments;

the prevalence and severity of any side effects, including any limitations or warnings contained in a product’s approved labeling;

the prevalence and severity of any side effects resulting from the procedure by which our product candidates are administered;

relative convenience and ease of administration;

the willingness of the target patient population to try new therapies and of physicians to prescribe these therapies;

the strength of marketing and distribution support and timing of market introduction of competitive products;

publicity concerning our products or competing products and treatments; and

sufficient third-party insurance coverage or reimbursement.

Even if a potential product displays a favorable efficacy and safety profile in preclinical studies and clinical trials, market acceptance of the product will not
be known until after it is launched. Our efforts to educate the medical community and third-party payors on the benefits of the product candidates may
require  significant  resources  and  may  never  be  successful.  Such  efforts  to  educate  the  marketplace  may  require  more  resources  than  are  required  by
conventional technologies.

A variety of risks associated with international operations could hurt our business.

If any of our product candidates are approved for commercialization, it is our current intention to market them on a worldwide basis, either alone or in
collaboration with others. In addition, we conduct development activities in various jurisdictions throughout the world. We expect that we will be subject to
additional risks related to engaging in international operations, including:

●

●

●

●

different regulatory requirements for approval of drugs and biologics in foreign countries;

reduced protection for intellectual property rights;

unexpected changes in tariffs, trade barriers and regulatory requirements;

economic weakness, including inflation, or political instability in particular foreign economies and markets;

●

compliance with tax, employment, immigration and labor laws for employees living or traveling abroad;

foreign currency  fluctuations,  which  could  result  in  increased  operating  expenses  and  reduced  revenue,  and  other  obligations  incident  to  doing
business in another country;

workforce uncertainty in countries where labor unrest is more common than in the United States and Israel;

production shortages resulting from any events affecting raw material supply or manufacturing capabilities abroad; and

business interruptions resulting from geopolitical actions, including war and terrorism, global outbreaks of disease, or natural disasters including
earthquakes, typhoons, floods and fires.

We have not undertaken a systematic analysis of the potential consequences to our business as a result of any such natural disaster, public health crisis or
pandemic diseases and do not have an applicable recovery plan in place. In addition, if any of our third-party contract manufacturers are affected by natural
disasters, such as earthquakes, power shortages or outages, floods, wildfire, public health crises, such as pandemics and epidemics terrorism or other events
outside  of  our  control,  our  business  and  operating  results  could  suffer.  For  example,  in  December  2019,  a  strain  of  coronavirus  was  reported  to  have
surfaced in Wuhan, China. At this point, the extent to which the coronavirus may impact our business and operating results is uncertain. We carry only
limited  business  interruption  insurance  that  would  compensate  us  for  actual  losses  from  interruption  of  our  business  that  may  occur  and  any  losses  or
damages incurred by us in excess of insured amounts could cause our business to materially suffer.

The insurance coverage and reimbursement status of newly approved products is uncertain. Failure to obtain or maintain adequate coverage and
reimbursement for any of our product candidates that are approved could limit our ability to market those products and compromise our ability
to generate revenue.

The availability of reimbursement by governmental and private payors is essential for most patients to be able to afford expensive treatments. Sales of our
product candidates will depend substantially, both in the U.S. and abroad, on the extent to which the costs of our product candidates will be paid by health
maintenance,  managed  care,  pharmacy  benefit  and  similar  healthcare  management  organizations,  or  reimbursed  by  government  health  administration
authorities, private health coverage insurers and other third-party payors. If reimbursement is not available, or is available only to limited levels, we may
not  be  able  to  successfully  commercialize  our  product  candidates.  Even  if  coverage  is  provided,  the  approved  reimbursement  amount  may  not  be  high
enough to allow us to establish or maintain pricing sufficient to realize a sufficient return on our investment.

There  is  significant  uncertainty  related  to  the  insurance  coverage  and  reimbursement  of  newly  approved  products.  In  the  United  States,  the  principal
decisions about reimbursement for new medicines are typically made by the Centers for Medicare & Medicaid Services, or CMS, an agency within the U.S.
Department of Health and Human Services, as CMS decides whether and to what extent a new medicine will be covered and reimbursed under Medicare.
Private payors tend to follow CMS to a substantial degree. It is difficult to predict what CMS will decide with respect to reimbursement for fundamentally
novel products such as ours, as there is no body of established practices and precedents for these new products. Reimbursement agencies in Europe may be
more  conservative  than  CMS.  For  example,  a  number  of  cancer  drugs  have  been  approved  for  reimbursement  in  the  United  States  and  have  not  been
approved for reimbursement in certain European countries.

The  intended  use  of  a  drug  product  by  a  physician  can  also  affect  pricing.  For  example,  CMS  could  initiate  a  National  Coverage  Determination
administrative procedure, by which the agency determines which uses of a therapeutic product would and would not be reimbursable under Medicare. This
determination process can be lengthy, thereby creating a long period during which the future reimbursement for a particular product may be uncertain.

Outside  the  United  States,  international  operations  are  generally  subject  to  extensive  governmental  price  controls  and  other  market  regulations,  and  we
believe the increasing emphasis on cost-containment initiatives in Europe, Canada, and other countries is likely to put pressure on the pricing and usage of
any  of  our  product  candidates  that  are  approved  for  marketing.  In  many  countries,  the  prices  of  medical  products  are  subject  to  varying  price  control
mechanisms as part of national health systems. In general, the prices of medicines under such systems are substantially lower than in the United States.
Other countries allow companies to fix their own prices for medicines, but monitor and control company profits. Additional foreign price controls or other
changes in pricing regulation could restrict the amount that we are able to charge for our product candidates. Accordingly, in markets outside the United
States, the reimbursement for our products may be reduced compared with the United States and may be insufficient to generate commercially reasonable
revenue and profits.

Moreover,  increasing  efforts  by  governmental  and  third-party  payors,  in  the  United  States  and  abroad,  to  cap  or  reduce  healthcare  costs,  resulting  in
legislation and reforms may cause such organizations to limit both coverage and level of reimbursement for new products approved and, as a result, they
may not cover or provide adequate payment for our product candidates. We expect to experience pricing pressures in connection with the sale of any of our
product candidates, due to the trend toward managed healthcare, the increasing influence of health maintenance organizations and additional legislative
changes. The downward pressure on healthcare costs in general, particularly prescription drugs and surgical procedures and other treatments, has become
very intense. As a result, increasingly high barriers are being erected to the entry of new products.

The prescription for or promotion of off-label uses of our products by physicians could adversely affect our business.

Any regulatory approval of our products is limited to those specific diseases and indications for which our products have been deemed safe and effective by
the  FDA  or  similar  authorities  in  other  jurisdictions.  In  addition,  any  new  indication  for  an  approved  product  also  requires  regulatory  approval.  If  we
produce an approved therapeutic product, we will rely on physicians to prescribe and administer it as we have directed and for the indications described on
the labeling. It is not, however, uncommon for physicians to prescribe medication for unapproved, or “off-label,” uses or in a manner that is inconsistent
with  the  manufacturer’s  directions.  To  the  extent  such  off-label  uses  and  departures  from  our  administration  directions  become  pervasive  and  produce
results such as reduced efficacy or other adverse effects, the reputation of our products in the marketplace may suffer. In addition, off-label uses may cause
a decline in our revenue or potential revenue, to the extent that there is a difference between the prices of our product for different indications.

Furthermore, while physicians may choose to prescribe our drugs for off-label uses, our ability to promote the products is limited to those indications that
are  specifically  approved  by  the  FDA  or  other  regulators.  Although  regulatory  authorities  generally  do  not  regulate  the  behavior  of  physicians,  they  do
restrict communications by companies with respect to off-label use. If our promotional activities fail to comply with these regulations or guidelines, we
may be subject to warnings from, or enforcement action by, these authorities. In addition, failure to follow FDA rules and guidelines relating to promotion
and advertising can result in the FDA’s refusal to approve a product, the suspension or withdrawal of an approved product from the market, product recalls,
fines, disgorgement of money, operating restrictions, injunctions or criminal prosecution.

Due  to  the  small  target  patient  populations  for  some  of  our  product  candidates,  we  face  uncertainty  related  to  pricing  and  reimbursement  for
these product candidates.

Some of our target patient populations for our initial product candidates are relatively small, as a result of which the pricing and reimbursement of our
product candidates, if approved, must be adequate to support commercial infrastructure. If we are unable to obtain adequate levels of reimbursement, our
ability to successfully market and sell our product candidates will be adversely affected. Inadequate reimbursement for such services may lead to physician
resistance and adversely affect our ability to market or sell our products.

Risks Related to Our Business Operations

Our  future  success  depends  on  our  ability  to  retain  key  employees,  consultants  and  advisors  and  to  attract,  retain  and  motivate  qualified
personnel.

We  are  highly  dependent  on  principal  members  of  our  executive  team  listed  under  “Management”  in  this  report,  including  Prof.  Dror  Harats,  our  chief
executive officer, the loss of whose services may adversely impact the achievement of our objectives. While we have entered into employment agreements
with each of our executive officers, any of them could leave our employment at any time, as all of our employees are “at will” employees. Recruiting and
retaining  other  qualified  employees,  consultants  and  advisors  for  our  business,  including  scientific  and  technical  personnel,  will  also  be  critical  to  our
success. There is currently a shortage of skilled executives in our industry, which is likely to continue. As a result, competition for skilled personnel is
intense and the turnover rate can be high. We may not be able to attract and retain personnel on acceptable terms given the competition among numerous
pharmaceutical and biotechnology companies for individuals with similar skill sets. In addition, failure to succeed in preclinical studies or clinical trials
may  make  it  more  challenging  to  recruit  and  retain  qualified  personnel. The  inability  to  recruit  or  loss  of  the  services  of  any  executive,  key  employee,
consultant or advisor may impede the progress of our research, development and commercialization objectives.

Our collaborations with outside scientists and consultants may be subject to restriction and change.

We work with medical experts, chemists, biologists and other scientists at academic and other institutions, and consultants who assist us in our research,
development and regulatory efforts, including the members of our scientific advisory board. In addition, these scientists and consultants have provided, and
we expect that they will continue to provide, valuable advice regarding our programs and regulatory approval processes. These scientists and consultants
are not our employees and may have other commitments that would limit their future availability to us. If a conflict of interest arises between their work for
us  and  their  work  for  another  entity,  we  may  lose  their  services.  In  addition,  we  are  limited  in  our  ability  to  prevent  them  from  establishing  competing
businesses  or  developing  competing  products.  For  example,  if  a  key  scientist  acting  as  a  principal  investigator  in  any  of  our  clinical  trials  identifies  a
potential product or compound that is more scientifically interesting to his or her professional interests, his or her availability to remain involved in our
clinical trials could be restricted or eliminated.

We will need to expand our organization and we may experience difficulties in managing this growth, which could disrupt our operations.

As of March 1, 2020, we had 38 employees. As we mature and undertake the activities required to advance our product candidates into later stage clinical
development  and  to  operate  as  a  public  company,  we  expect  to  expand  our  full-time  employee  base  and  to  hire  more  consultants  and  contractors.  Our
management may need to divert a disproportionate amount of its attention away from our day-to-day activities and devote a substantial amount of time to
managing  these  growth  activities.  We  may  not  be  able  to  effectively  manage  the  expansion  of  our  operations,  which  may  result  in  weaknesses  in  our
infrastructure, operational mistakes, loss of business opportunities, loss of employees and reduced productivity among remaining employees. Our expected
growth could require significant capital expenditures and may divert financial resources from other projects, such as the development of additional product
candidates. If our management is unable to effectively manage our growth, our expenses may increase more than expected, our ability to generate or grow
revenue  could  be  compromised,  and  we  may  not  be  able  to  implement  our  business  strategy.  Our  future  financial  performance  and  our  ability  to
commercialize product candidates and compete effectively will depend, in part, on our ability to effectively manage any future growth.

Our employees, principal investigators, consultants and commercial partners may engage in misconduct or other improper activities, including
non-compliance with regulatory standards and requirements and insider trading.

We are exposed to the risk of fraud or other misconduct by our employees, principal investigators, consultants and commercial partners. Misconduct by
these parties could include intentional failures to comply with the regulations of the FDA and non-U.S. regulators, provide accurate information to the FDA
and non-U.S. regulators, comply with healthcare fraud and abuse laws and regulations in the United States and abroad, 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, misconduct, kickbacks, self-dealing and other abusive practices. These laws and regulations may
restrict  or  prohibit  a  wide  range  of  pricing,  discounting,  marketing  and  promotion,  sales  commission,  customer  incentive  programs  and  other  business
arrangements. Such misconduct could also involve the improper use of information obtained in the course of clinical trials, which could result in regulatory
sanctions and cause serious harm to our reputation. We have adopted a code of conduct applicable to all of our employees, but it is not always possible to
identify and deter employee misconduct, and the precautions we take to detect and prevent this activity may not be effective in controlling unknown or
unmanaged risks or losses or in protecting us from governmental investigations or other actions or lawsuits stemming from a failure to comply with these
laws or regulations. If any such actions are instituted against us, and we are not successful in defending ourselves or asserting our rights, those actions
could have a significant impact on our business, including the imposition of significant fines or other sanctions.

Pandemics such as the coronavirus could have an adverse impact on our developmental programs and our financial condition.

In  December  2019,  an  outbreak  of  a  novel  strain  of  coronavirus,  or  the  SARS-CoV-2  coronavirus,  which  results  in  COVID-19,  had  ripple  effects  to
businesses around the world, negatively impacted activity and operations, including extended shutdowns of certain businesses, in many countries, including
the  USA,  European  countries  and  Israel,  where  our  operations  are.  The  list  of  countries  and  regions  affected  by  the  coronavirus  outbreak  is  constantly
changing and our clinical trial sites may be located in regions currently being afflicted by the COVID-19 pandemic. Any outbreak of contagious diseases,
or  other  adverse  public  health  developments,  could  have  a  material  and  adverse  effect  on  our  business  operations.  These  could  include  disruptions  or
restrictions on our ability to travel, pursue partnerships and other business transactions, conduct clinical trials, make shipments of biologic materials, as
well as be impacted by the temporary closure of the facilities of suppliers and clinical trial sites. Any disruption of suppliers, clinical trial sites or access to
patients would likely impact our clinical trial enrollment progress and rates as well as our ability to access capital through the financial markets. The extent
to which the coronavirus impacts our business will depend on future developments, which are highly uncertain and cannot be predicted, including new
information which may emerge concerning the severity of the coronavirus and the actions to contain the coronavirus or treat its impact, among others.

We face potential product liability, and, if successful claims are brought against us, we may incur substantial liability and costs. If the use of our
product candidates harms patients, or is perceived to harm patients even when such harm is unrelated to our product candidates, our regulatory
approvals could be revoked or otherwise negatively impacted and we could be subject to costly and damaging product liability claims.

The use of our product candidates in clinical trials and the sale of any products for which we obtain marketing approval exposes us to the risk of product
liability claims. Product liability claims might be brought against us by consumers, healthcare providers, pharmaceutical companies or others selling or
otherwise coming into contact with our product candidates. There is a risk that our product candidates may induce adverse events. If we cannot successfully
defend against product liability claims, we could incur substantial liability and costs. In addition, regardless of merit or eventual outcome, product liability
claims may result in:

●

●

●

●

●

●

●

●

impairment of our business reputation;

withdrawal of clinical trial participants;

costs due to related litigation;

distraction of management’s attention from our primary business;

substantial monetary awards to patients or other claimants;

the inability to commercialize our product candidates;

decreased demand for our product candidates, if approved for commercial sale; and

impairment of our ability to obtain product liability insurance coverage.

We  carry  combined  public  and  products  liability  (including  human  clinical  trials  extension)  insurance  of  $5.0  million  per  occurrence  and  $5.0  million
aggregate limit, with extension to $10.0 million for the Phase 3 study in rGBM and for the Phase 3 study in ovarian cancer. We believe our product liability
insurance coverage is sufficient in light of our current clinical programs; however, we may not be able to maintain insurance coverage at a reasonable cost
or in sufficient amounts to protect us against losses due to liability. If we obtain marketing approval for any product candidates, we intend to expand our
insurance coverage to include the sale of commercial products, but we may not be able to obtain product liability insurance on commercially reasonable
terms or in adequate amounts. On occasion, large judgments have been awarded in class action lawsuits based on drugs or medical treatments that had
unanticipated  adverse  effects.  A  successful  product  liability  claim  or  series  of  claims  brought  against  us  could  cause  our  share  price  to  decline  and,  if
judgments exceed our insurance coverage, could materially and adversely affect our financial position.

Patients with the diseases targeted by some of our product candidates are often already in severe and advanced stages of disease and have both known and
unknown significant pre- existing and potentially life-threatening health risks. During the course of treatment, patients may suffer adverse events, including
death, for reasons that may be related to our product candidates. Such events could subject us to costly litigation, require us to pay substantial amounts of
money to injured patients, delay, negatively impact or end our opportunity to receive or maintain regulatory approval to market our products, or require us
to suspend or abandon our commercialization efforts. Even in a circumstance in which we do not believe that an adverse event is related to our product
candidate,  the  investigation  into  the  circumstance  may  be  time-consuming  or  inconclusive.  These  investigations  may  harm  our  reputation,  delay  our
regulatory approval process, limit the type of regulatory approvals our product candidates receive or maintain, and compromise the market acceptance of
any of our product candidates that receive regulatory approval. As a result of these factors, a product liability claim, even if successfully defended, could
hurt our business and impair our ability to generate revenue.

If  our  existing  or  future  manufacturing  facility  is  damaged  or  destroyed,  or  production  at  any  of  those  facilities  is  otherwise  interrupted,  our
business and prospects would be negatively affected.

We have a manufacturing facility for commercial scale production. If our existing or future manufacturing facilities, or the equipment in it, is damaged or
destroyed, we likely would not be able to quickly or inexpensively replace our manufacturing capacity and possibly would not be able to replace it at all.
Any new facility needed to replace our existing or future manufacturing facility would need to comply with the necessary regulatory requirements, and be
tailored  to  our  manufacturing  requirements  and  processes.  We  would  need  FDA  approval  before  using  any  product  candidates  manufactured  at  a  new
facility  in  clinical  trials  or  selling  any  products  that  are  ultimately  approved.  Such  an  event  could  delay  our  clinical  trials  or,  if  any  of  our  product
candidates are approved by the FDA, reduce or eliminate our product sales.

If we fail to comply with environmental, health and safety laws and regulations, we could become subject to fines or penalties or incur costs that
could have a material adverse effect on the success of our business.

We are subject to numerous environmental, health and safety laws and regulations, including those governing laboratory procedures and the handling, use,
storage,  treatment  and  disposal  of  hazardous  materials  and  wastes.  Our  operations  involve  the  use  of  hazardous  and  flammable  materials,  including
chemicals and biological materials. Our operations also produce hazardous waste products. We generally contract with third parties for the disposal of these
materials and wastes. We cannot eliminate the risk of contamination or injury from these materials. In the event of contamination or injury resulting from
our  use  of  hazardous  materials,  we  could  be  held  liable  for  any  resulting  damages,  and  any  liability  could  exceed  our  resources.  We  also  could  incur
significant costs associated with civil or criminal fines and penalties.

Although we maintain workers’ compensation insurance to cover us for costs and expenses we may incur due to injuries to our employees resulting from
the use of hazardous materials or other work-related injuries, this insurance may not provide adequate coverage against potential liabilities. In addition, we
may incur substantial costs in order to comply with current or future environmental, health and safety laws and regulations. These current or future laws
and  regulations  may  impair  our  research,  development  or  production  efforts.  Failure  to  comply  with  these  laws  and  regulations  also  may  result  in
substantial fines, penalties or other sanctions.

If  our  shipping  capabilities  become  unavailable  due  to  an  accident,  an  act  of  terrorism,  a  labor  strike  or  other  similar  event,  our  supply,
production and distribution processes could be disrupted.

Some of our raw materials for the manufacturing of VB-111, and VB-111 itself, must be transported at a temperature controlled cold chain at temperatures
varying between -4 degrees Celsius to -70 degrees Celsius (25 to -94 degrees Fahrenheit) to ensure their quality and vitality. Not all shipping or distribution
channels are equipped to transport at these temperatures. If any of our shipping or distribution channels become inaccessible because of a serious accident,
an act of terrorism, global health pandemic, a labor strike or other similar event, we may experience disruptions in our continued supply of raw materials,
delays in our production process or a reduction in our ability to distribute our therapeutics to our customers.

We may use our financial and human resources to pursue a particular research program or product candidate and fail to capitalize on programs
or product candidates that may be more profitable or for which there is a greater likelihood of success.

Because we have limited resources, we may forego or delay pursuit of opportunities with certain programs or product candidates or for indications that later
prove to have greater commercial potential. Our resource allocation decisions may cause us to fail to capitalize on viable commercial products or profitable
market  opportunities.  Our  spending  on  current  and  future  research  and  development  programs  for  product  candidates  may  not  yield  any  commercially
viable products. If we do not accurately evaluate the commercial potential or target market for a particular product candidate, we may relinquish valuable
rights  to  that  product  candidate  through  strategic  collaboration,  licensing  or  other  royalty  arrangements  in  cases  in  which  it  would  have  been  more
advantageous for us to retain sole development and commercialization rights to such product candidate, or we may allocate internal resources to a product
candidate in a therapeutic area in which it would have been more advantageous to enter into a collaboration arrangement.

We  will  continue  to  incur  significant  increased  costs  as  a  result  of  operating  as  a  public  company,  and  our  management  will  continue  to  be
required to devote substantial time to new compliance initiatives.

As  a  public  company,  we  will  continue  to  incur  significant  legal,  accounting  and  other  expenses.  In  addition,  the  Sarbanes-Oxley Act,  as  well  as  rules
subsequently implemented by the Securities and Exchange Commission, or SEC, and The NASDAQ Global Market have imposed various requirements on
public companies. Shareholder activism, the current political environment and the current high level of government intervention and regulatory reform may
lead to substantial new regulations and disclosure obligations, which may lead to additional compliance costs and impact the manner in which we operate
our  business  in  ways  we  cannot  currently  anticipate.  Our  management  and  other  personnel  will  need  to  devote  a  substantial  amount  of  time  to  these
compliance initiatives. Moreover, these rules and regulations will increase our legal and financial compliance costs and will make some activities more
time-consuming and costly. For example, we expect these rules and regulations, as well as the increase in the number of class actions and other securities
litigation filed against publicly traded life sciences companies, to make it more difficult and more expensive for us to obtain director and officer liability
insurance  and  we  may  be  required  to  incur  substantial  costs  to  maintain  our  current  levels  of  such  coverage.  While  compliance  with  these  additional
requirements will result in increased costs to us, we cannot accurately predict or estimate at this time the amount of additional costs we may incur as a
public company under both U.S. and Israeli laws.

Table of Contents

Additionally, as of December 31, 2019, we were no longer an “emerging growth company,” as defined in the JOBS Act, and are now required to comply
with additional disclosure and reporting requirements. These additional reporting requirements may increase our legal and financial compliance costs and
cause management and other personnel to divert attention from operational and other business matters to devote substantial time to these public company
requirements. Presently we qualify as a non-accelerated filer, meaning we have a public float of less than $75 million measured as of the last business day
of our most recently completed second fiscal quarter, and thus remain exempt from Section 404(b) of the Sarbanes-Oxley Act, which generally requires
public companies (including foreign private issuers) to provide an independent auditor attestation of the effectiveness of their internal controls. However, in
the event that we become an accelerated filer, we will incur additional costs in connection with compliance with Section 404(b) of the Sarbanes-Oxley Act.

We are subject to foreign currency exchange risk, and fluctuations between the U.S. dollar and the NIS, the Euro and other non-U.S. currencies
may negatively affect our earnings and results of operations.

We operate in a number of different currencies. While the dollar is our functional and reporting currency and investments in our share capital have been
denominated in dollars, our financial results may be adversely affected by fluctuations in currency exchange rates as a significant portion of our operating
expenses, including our salary-related and manufacturing expenses are denominated in the NIS.

We are exposed to the risks that the NIS may appreciate relative to the dollar, or, if the NIS instead devalues relative to the dollar, that the inflation rate in
Israel may exceed such rate of devaluation of the NIS, or that the timing of such devaluation may lag behind inflation in Israel. In any such event, the dollar
cost of our operations in Israel would increase and our dollar- denominated results of operations would be adversely affected. We cannot predict any future
trends in the rate of inflation in Israel or the rate of devaluation (if any) of the NIS against the dollar. For example, the average exchange rate of the dollar
against the NIS decreased materially in 2020, and decreases moderately in 2019 and in 2018. Market volatility and currency fluctuations may limit our
ability to cost- effectively hedge against our foreign currency exposure and, in addition, our ability to hedge our exposure to currency fluctuations in certain
emerging markets may be limited. Hedging strategies may not eliminate our exposure to foreign exchange rate fluctuations and may involve costs and risks
of  their  own,  such  as  devotion  of  management  time,  external  costs  to  implement  the  strategies  and  potential  accounting  implications.  Foreign  currency
fluctuations, independent of the performance of our underlying business, could lead to materially adverse results or could lead to positive results that are
not repeated in future periods.

Risks Related to Our Intellectual Property

We depend on our license agreement with Janssen Vaccines & Prevention B.V. and if we cannot meet requirements under such license agreement,
we could lose the rights to our products, which could have a material adverse effect on our business.

VB-111 incorporates an adenoviral vector as the delivery vehicle, which its manufacturing is based on our rights under a license agreement with Janssen
Vaccines & Prevention B.V. If we fail to meet our obligations under this license agreement, including various diligence, milestone payment, royalty and
other obligations, Janssen Vaccines & Prevention B.V. has the right to terminate our license, and upon the effective date of such termination, our right to
use the licensed technology would terminate. We may enter into additional agreements in the future with Janssen Vaccines & Prevention B.V. that may
impose similar obligations on us. While we would expect to exercise all rights and remedies available to us, including attempting to cure any breach by us,
and otherwise seek to preserve our rights under the patents and other technology licensed to us, we may not be able to do so in a timely manner, at an
acceptable cost or at all. Any uncured, material breach under the license agreement could result in our loss of rights and may lead to a complete termination
of  our  product  development  and  any  commercialization  efforts  for  the  applicable  product  candidates  since  there  are  currently  no  significant  similar
alternatives on the market.

If we are unable to obtain or protect intellectual property rights related to our product candidates, we may not be able to obtain exclusivity for our
product candidates or prevent others from developing similar competitive products.

We  rely  upon  a  combination  of  patents,  trade  secret  protection  and  confidentiality  agreements  to  protect  the  intellectual  property  related  to  our  product
candidates. The strength of patents in the biotechnology and pharmaceutical field involves complex legal and scientific questions and can be uncertain. The
patent applications that we own or in-license may fail to result in issued patents with claims that cover our product candidates in the United States or in
other foreign countries. There is no assurance that all of the potentially relevant prior art relating to our patents and patent applications has been found,
which can invalidate a patent or prevent a patent from issuing from a pending patent application. Even if patents do successfully issue and even if such
patents  cover  our  product  candidates,  third  parties  may  challenge  their  validity,  enforceability  or  scope,  which  may  result  in  the  patent  claims  being
narrowed  or  invalidated.  Furthermore,  even  if  they  are  unchallenged,  our  patents  and  patent  applications  may  not  adequately  protect  our  intellectual
property,  provide  exclusivity  for  our  product  candidates  or  prevent  others  from  designing  around  our  claims.  Any  of  these  outcomes  could  impair  our
ability to prevent competition from third parties.

24

 
 
 
 
 
 
 
 
 
 
 
 
Table of Contents

If the patent applications we hold or have in-licensed with respect to our programs or product candidates fail to issue, if the breadth or strength of our patent
protection  is  threatened,  or  if  our  patent  portfolio  fails  to  provide  meaningful  exclusivity  for  our  product  candidates,  it  could  dissuade  companies  from
collaborating  with  us  to  develop  product  candidates  and  threaten  our  ability  to  commercialize  future  products.  Several  patent  applications  covering  our
product candidates have been filed recently. We cannot offer any assurances about which, if any, applications will issue as patents, the breadth of any such
issued patent claims or whether any issued claims will be found invalid and unenforceable or will be threatened by third parties. Any successful opposition
to these patents or any other patents owned by or licensed to us could deprive us of rights necessary for the successful commercialization of any product
candidates  that  we  may  develop.  Further,  if  we  encounter  delays  in  regulatory  approvals,  the  period  of  time  during  which  we  could  market  a  product
candidate under patent protection could be reduced. Since patent applications in the United States and most other countries are confidential for a period of
time after filing, and some remain so until issued, we cannot be certain that we or our licensors were the first to file any patent application related to a
product candidate. Furthermore, if third parties have filed such patent applications, an interference proceeding in the United States can be initiated by a
third party to determine who was the first to invent any of the subject matter covered by the patent claims of our applications. In addition, patents have a
limited lifespan. In the United States, the natural expiration of a patent is generally 20 years after it is filed. Various extensions may be available, but the
life of a patent, and the protection it affords, is limited. Even if patents covering our product candidates are obtained, once the patent life has expired for a
product, we may be open to competition from generic medications. This risk is material in light of the length of the development process of our products
and lifespan of our current patent portfolio.

In addition to the protection afforded by patents, we rely on trade secret protection and confidentiality agreements to protect proprietary know-how that is
not patentable or that we elect not to patent, processes for which patents are difficult to enforce and any other elements of our product candidate discovery
and development processes that involve proprietary know- how, information or technology that is not covered by patents. However, trade secrets can be
difficult to protect. We seek to protect our proprietary technology and processes, in part, by entering into confidentiality agreements with our employees,
consultants,  scientific  advisors  and  contractors.  We  also  seek  to  preserve  the  integrity  and  confidentiality  of  our  data  and  trade  secrets  by  maintaining
physical security of our premises and physical and electronic security of our information technology systems. Security measures may be breached, and we
may  not  have  adequate  remedies  for  any  breach.  In  addition,  our  trade  secrets  may  otherwise  become  known  or  be  independently  discovered  by
competitors. Although we expect all of our employees and consultants to assign their inventions to us, and all of our employees, consultants, advisors and
any third parties who have access to our proprietary know-how, information or technology to enter into confidentiality agreements, we cannot provide any
assurances that all such agreements have been duly executed or that our trade secrets and other confidential proprietary information will not be disclosed or
that  competitors  will  not  otherwise  gain  access  to  our  trade  secrets  or  independently  develop  substantially  equivalent  information  and  techniques.
Misappropriation  or  unauthorized  disclosure  of  our  trade  secrets  could  impair  our  competitive  position  and  may  have  a  material  adverse  effect  on  our
business. Additionally, if the steps taken to maintain our trade secrets are deemed inadequate, we may have insufficient recourse against third parties for
misappropriating the trade secret. In addition, others may independently discover our trade secrets and proprietary information. For example, the FDA, as
part  of  its  Transparency  Initiative,  is  currently  considering  whether  to  make  additional  information  publicly  available  on  a  routine  basis,  including
information  that  we  may  consider  to  be  trade  secrets  or  other  proprietary  information,  and  it  is  not  clear  at  the  present  time  how  the  FDA’s  disclosure
policies may change in the future, if at all.

Further, the laws of some foreign countries do not protect proprietary rights to the same extent or in the same manner as the laws of the United States. As a
result, we may encounter significant problems in protecting and defending our intellectual property both in the United States and abroad. If we are unable
to prevent material disclosure of the non-patented intellectual property related to our technologies to third parties, and there is no guarantee that we will
have any such enforceable trade secret protection, we may not be able to establish or maintain a competitive advantage in our market.

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

Our commercial success depends in part on our avoiding infringement of the patents and proprietary rights of third parties. There is a substantial amount of
litigation,  both  within  and  outside  the  United  States,  involving  patent  and  other  intellectual  property  rights  in  the  biotechnology  and  pharmaceutical
industries,  including  patent  infringement  lawsuits,  interferences,  oppositions  and  inter  partes  review  proceedings  before  the  U.S.  Patent  and  Trademark
Office, or U.S. PTO, and corresponding foreign patent offices. Numerous U.S. and foreign issued patents and pending patent applications, which are owned
by third parties, exist in the fields in which we are pursuing development candidates. As the biotechnology and pharmaceutical industries expand and more
patents are issued, the risk increases that our product candidates may be subject to claims of infringement of the patent rights of third parties.

Third parties may assert that we are employing their proprietary technology without authorization. There may be third-party patents or patent applications
with  claims  to  materials,  formulations,  methods  of  manufacture  or  methods  for  treatment  related  to  the  use  or  manufacture  of  our  product  candidates.
Because patent applications can take many years to issue, there may be currently pending patent applications which may later result in issued patents that
our  product  candidates  may  be  accused  of  infringing.  In  addition,  third  parties  may  obtain  patents  in  the  future  and  claim  that  use  of  our  technologies
infringes upon these patents. If any third-party patents were held by a court of competent jurisdiction to cover the manufacturing process of any of our
product candidates, any molecules formed during the manufacturing process or any final product itself, the holders of any such patents may be able to block
our ability to commercialize such product candidate unless we obtained a license under the applicable patents, or until such patents expire. Similarly, if any
third-party patents were held by a court of competent jurisdiction to cover aspects of our formulations, processes for manufacture or methods of use, the
holders of any such patents may be able to block our ability to develop and commercialize the applicable product candidate unless we obtained a license or
until such patent expires. In either case, such a license may not be available on commercially reasonable terms or at all.

25

 
 
 
 
 
 
 
 
 
Table of Contents

Parties  making  claims  against  us  may  obtain  injunctive  or  other  equitable  relief,  which  could  effectively  block  our  ability  to  further  develop  and
commercialize one or more of our product candidates. Defense of these claims, regardless of their merit, would involve substantial litigation expense and
would be a substantial diversion of employee resources from our business. In the event of a successful claim of infringement against us, we may have to
pay substantial damages, including treble damages and attorneys’ fees for willful infringement, pay royalties, redesign our infringing products or obtain one
or more licenses from third parties, which may be impossible or require substantial time and monetary expenditure.

We may not be successful in obtaining or maintaining necessary rights to pharmaceutical product components and processes for our development
pipeline through acquisitions and in- licenses.

Presently we have rights to the intellectual property, through licenses from Janssen Vaccines & Prevention B.V. and under patents that we own, to develop
our  product  candidates.  Because  our  programs  may  involve  additional  product  candidates  that  may  require  the  use  of  proprietary  rights  held  by  third
parties,  the  growth  of  our  business  may  depend  in  part  on  our  ability  to  acquire,  in-license  or  use  these  proprietary  rights.  In  addition,  our  product
candidates may require specific formulations to work effectively and efficiently and these rights may be held by others. We may be unable to acquire or in-
license any compositions, methods of use, processes or other third- party intellectual property rights from third parties that we identify. The licensing and
acquisition  of  third-party  intellectual  property  rights  is  a  competitive  area,  and  a  number  of  more  established  companies  are  also  pursuing  strategies  to
license or acquire third-party intellectual property rights that we may consider attractive. These established companies may have a competitive advantage
over us due to their size, cash resources and greater clinical development and commercialization capabilities. In addition, companies that perceive us to be a
competitor may be unwilling to assign or license rights to us. We also may be unable to license or acquire third-party intellectual property rights on terms
that would allow us to make an appropriate return on our investment.

We may enter into license agreements with third parties, and if we fail to comply with our obligations in such agreements under which we license
intellectual property rights from third parties or otherwise experience disruptions to our business relationships with our licensors, we could lose
license rights that are important to our business.

We may need to obtain licenses from third parties to advance our research or allow commercialization of our product candidates, and we have done so from
time to time. We may fail to obtain any of these licenses at a reasonable cost or on reasonable terms, if at all. In that event, we may be required to expend
significant time and resources to develop or license replacement technology. If we are unable to do so, we may be unable to develop or commercialize the
affected product candidates.

In many cases, patent prosecution of our in-licensed technology is controlled solely by the licensor. If our licensors fail to obtain and maintain patent or
other protection for the proprietary intellectual property we license from them, we could lose our rights to the intellectual property or our exclusivity with
respect to those rights, and our competitors could market competing products using the intellectual property. In some cases, we control the prosecution of
patents resulting from licensed technology. In the event we breach any of our obligations related to such prosecution, we may incur significant liability to
our licensing partners. Licensing of intellectual property is of critical importance to our business and involves complex legal, business and scientific issues
and  is  complicated  by  the  rapid  pace  of  scientific  discovery  in  our  industry.  Disputes  may  arise  regarding  intellectual  property  subject  to  a  licensing
agreement, including:

●

●

●

●

●

●

the scope of rights granted under the license agreement and other interpretation-related issues;

the extent to which our technology and processes infringe on intellectual property of the licensor that is not subject to the licensing agreement;

the sublicensing of patent and other rights under any collaboration relationships we might enter into in the future;

our diligence obligations under the license agreement and what activities satisfy those diligence obligations;

the ownership of inventions and know-how resulting from the joint creation or use of intellectual property by our licensors and us and our partners;
and

the priority of invention of patented technology.

If disputes over intellectual property that we have licensed prevent or impair our ability to maintain our current licensing arrangements on acceptable terms,
we may be unable to successfully develop and commercialize the affected product candidates.

We may be involved in lawsuits to protect or enforce our patents or the patents of our licensors, which could be expensive, time-consuming and
unsuccessful.

Competitors may infringe our patents or the patents of our licensors. To counter infringement or unauthorized use, we may be required to file infringement
claims, which can be expensive and time-consuming. In addition, in an infringement proceeding, a court may decide that a patent of ours or our licensors is
not valid, is unenforceable or is not infringed, or may refuse to stop the other party from using the technology at issue on the grounds that our patents do
not  cover  the  technology  in  question.  An  adverse  result  in  any  litigation  or  defense  proceedings  could  put  one  or  more  of  our  patents  at  risk  of  being
invalidated or interpreted narrowly and could put our patent applications at risk of not issuing.

Interference proceedings provoked by third parties or brought by us may be necessary to determine the priority of inventions with respect to our patents or
patent applications or those of our licensors. An unfavorable outcome could require us to cease using the related technology or to attempt to license rights
to it from the prevailing party. Our business could be harmed if the prevailing party does not offer us a license on commercially reasonable terms. Our
defense of litigation or interference proceedings may fail and, even if successful, may result in substantial costs and distract our management and other
employees. We may not be able to prevent, alone or with our licensors, misappropriation of our intellectual property rights, particularly in countries where
the laws may not protect those rights as fully as in the United States.

Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation, there is a risk that some of our
confidential  information  could  be  compromised  by  disclosure  during  this  type  of  litigation.  There  could  also  be  public  announcements  of  the  results  of
hearings, motions or other interim proceedings or developments. If securities analysts or investors perceive these results to be negative, it could have a
material adverse effect on the trading price of our ordinary shares.

Recent  patent  reform  legislation  could  increase  the  uncertainties  and  costs  surrounding  the  prosecution  of  our  patent  applications  and  the
enforcement or defense of our issued patents.

Patent reform legislation (the Leahy-Smith Act) enacted in 2013 continues to increase the uncertainties and costs surrounding the prosecution of our patent
applications and the enforcement or defense of our issued patents. The Leahy-Smith Act introduced a number of significant changes to U.S. patent law,
including  provisions  that  affect  the  way  patent  applications  are  prosecuted  and  patent  litigation  is  conducted.  The  U.S.  PTO  continues  to  develop
regulations and procedures to govern administration of the Leahy-Smith Act, and many of the substantive changes to patent law associated with the Act, in
particular, the Inter Partes Review (IPR) proceedings. It remains to be seen what impact the Leahy-Smith Act will have on the operation of our business.
However, the Act and its implementation increases the uncertainties and costs surrounding the prosecution of our patent applications and the enforcement
or defense of our issued patents, all of which could have a material adverse effect on our business and financial condition.

We  may  be  subject  to  claims  that  our  employees,  consultants  or  independent  contractors  have  wrongfully  used  or  disclosed  confidential
information of third parties or that our employees have wrongfully used or disclosed alleged trade secrets of their former employers.

Certain of our key employees and personnel are or were previously employed at universities, medical institutions or other biotechnology or pharmaceutical
companies, including our competitors or potential competitors.

Although we try to ensure that our employees, consultants and independent contractors do not use the proprietary information or know-how of others in
their work for us, we may be subject to claims that we or our employees, consultants or independent contractors have inadvertently or otherwise used or
disclosed intellectual property, including trade secrets or other proprietary information, of any of our employee’s former employer or other third parties.
Litigation may be necessary to defend against these claims. If we fail in defending any such claims, in addition to paying monetary damages, we may lose
valuable intellectual property rights or personnel. Even if we are successful in defending against such claims, litigation could result in substantial costs and
be  a  distraction  to  management  and  other  employees.  Furthermore,  universities  or  medical  institutions  who  employ  some  of  our  key  employees  and
personnel  in  parallel  to  their  engagement  by  us  may  claim  that  intellectual  property  developed  by  such  person  is  owned  by  the  respective  academic  or
medical institution under the respective institution intellectual property policy or applicable law.

We  may  become  subject  to  claims  for  remuneration  or  royalties  for  assigned  service  invention  rights  by  our  employees,  which  could  result  in
litigation and adversely affect our business.

A significant portion of our intellectual property has been developed by our employees in the course of their employment for us. Under the Israeli Patent
Law,  5727-1967,  or  the  Patent  Law,  inventions  conceived  by  an  employee  during  the  term  and  as  part  of  the  scope  of  his  or  her  employment  with  a
company are regarded as “service inventions,” which belong to the employer, absent a specific agreement between the employee and employer giving the
employee  service  invention  rights.  The  Patent  Law  also  provides  that  if  there  is  no  such  agreement  between  an  employer  and  an  employee,  the  Israeli
Compensation and Royalties Committee, or the Committee, a body constituted under the Patent Law, shall determine whether the employee is entitled to
remuneration  for  his  inventions.  Recent  decisions  by  the  Committee  (which  have  been  upheld  by  the  Israeli  Supreme  Court  on  appeal)  have  created
uncertainty in this area, as it held that employees may be entitled to remuneration for their service inventions despite having specifically waived any such
rights.  Further,  the  Committee  has  not  yet  determined  the  method  for  calculating  this  remuneration  nor  the  criteria  or  circumstances  under  which  an
employee’s  waiver  of  his  right  to  remuneration  will  be  disregarded.  We  generally  enter  into  assignment-of-invention  agreements  with  our  employees
pursuant to which such individuals assign to us all rights to any inventions created in the scope of their employment or engagement with us. Although our
employees have agreed to assign to us service invention rights, we may face claims demanding remuneration in consideration for assigned inventions. As a
consequence of such claims, we could be required to pay additional remuneration or royalties to our current or former employees, or be forced to litigate
such claims, which could negatively affect our business.

We may be subject to claims challenging the inventorship or ownership of our patents and other intellectual property.

We  may  be  subject  to  claims  that  former  employees,  collaborators  or  other  third  parties  have  an  ownership  interest  in  our  patents  or  other  intellectual
property. We may have to in the future, ownership disputes arising, for example, from conflicting obligations of consultants or others who are involved in
developing our product candidates. Litigation may be necessary to defend against these and other claims challenging inventorship or ownership. If we fail
in defending any such claims, in addition to paying monetary damages, we may lose valuable intellectual property rights, such as exclusive ownership of,
or right to use, valuable intellectual property. Such an outcome could have a material adverse effect on our business. Even if we are successful in defending
against such claims, litigation could result in substantial costs and be a distraction to management and other employees.

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

Periodic maintenance fees, renewal fees, annuity fees and various other governmental fees on patents and applications will be due to be paid to the U.S.
PTO and various governmental patent agencies outside of the United States in several stages over the lifetime of the patents and applications. The U.S.
PTO  and  various  non-U.S.  governmental  patent  agencies  require  compliance  with  a  number  of  procedural,  documentary,  fee  payment  and  other  similar
provisions during the patent application process. There are situations in which non-compliance can result in abandonment or lapse of the patent or patent
application, resulting in partial or complete loss of patent rights in the relevant jurisdiction.

Issued patents covering our product candidates could be found invalid or unenforceable if challenged in court.

If  we  or  one  of  our  licensing  partners  initiated  legal  proceedings  against  a  third  party  to  enforce  a  patent  covering  one  of  our  product  candidates,  the
defendant may contend that the patent covering our product candidate is invalid, unenforceable or fails to cover the product candidate or the infringing
product.  In  patent  litigation  in  the  United  States,  defendants  commonly  allege  that  asserted  patent  claims  are  invalid  and  unenforceable.  Grounds  for  a
validity challenge could be an alleged failure to meet one or more of several statutory requirements, including lack of novelty, obviousness, lack of written
description, indefiniteness and non-enablement. Grounds for an unenforceability assertion could be an allegation that someone connected with prosecution
of the patent withheld relevant information from the U.S. PTO, or made a misleading statement, during prosecution. Third parties may also raise similar
claims before administrative bodies in the United States or abroad, even outside the context of litigation. Such mechanisms include re-examination, post
grant review, and equivalent proceedings in foreign jurisdictions, such as opposition proceedings. Such proceedings could result in revocation, amendments
to our patent claims or statements being made on the record such that our claims may no longer be construed to cover our product candidates. The outcome
following legal assertions of invalidity and unenforceability is unpredictable. With respect to the validity question, for example, we cannot be certain that
there is no invalidating prior art, of which we and the patent examiner were unaware during prosecution. If a defendant were to prevail on a legal assertion
of invalidity, unenforceability or non-infringement, we would lose at least part, and perhaps all, of the patent protection on our product candidates. Even if
resolved in our favor, litigation or other legal proceedings relating to intellectual property claims may cause us to incur significant expenses, and could
distract  our  technical  and  management  personnel  from  their  normal  responsibilities.  In  addition,  there  could  be  public  announcements  of  the  results  of
hearings, motions or other interim proceedings or developments, and if securities analysts or investors perceive these results to be negative, it could have a
substantial adverse effect on the market price of our ordinary shares. Such litigation or proceedings could substantially increase our operating losses and
reduce the resources available for development activities or any future sales, marketing or distribution activities.

Changes in U.S. patent law could diminish the value of patents in general, thereby impairing our ability to protect our products.

As is the case with other biotechnology companies, our success is heavily dependent on intellectual property, particularly patents. Obtaining and enforcing
patents in the biotechnology industry involve both technological and legal complexity, and is therefore costly, time- consuming and inherently uncertain. In
addition, the United States has recently enacted and is currently implementing wide-ranging patent reform legislation. Recent U.S. Supreme Court rulings
have narrowed the scope of patent protection available in certain circumstances and weakened the rights of patent owners in some situations. In addition to
increasing uncertainty with regard to our ability to obtain patents in the future, this combination of events has created uncertainty with respect to the value
of patents, once obtained. Depending on decisions by the U.S. Congress, the federal courts, and the U.S. PTO, the laws and regulations governing patents
could change in unpredictable ways that would weaken our ability to obtain new patents or to enforce our existing patents and patents that we might obtain
in the future.

We have not yet registered trademarks for a commercial trade name for some of our product candidates and failure to secure such registrations
could adversely affect our business.

We have not yet registered trademarks for a commercial trade name for some of our product candidates. During trademark registration proceedings, we
may  receive  rejections.  Although  we  would  be  given  an  opportunity  to  respond  to  those  rejections,  we  may  be  unable  to  overcome  such  rejections.  In
addition, in the U.S. PTO and in comparable agencies in many foreign jurisdictions, third parties are given an opportunity to oppose pending trademark
applications and to seek to cancel registered trademarks. Opposition or cancellation proceedings may be filed against our trademarks, and our trademarks
may not survive such proceedings. Moreover, any name we propose to use with our product candidates in the United States must be approved by the FDA,
regardless of whether we have registered it, or applied to register it, as a trademark. The FDA typically conducts a review of proposed product names,
including an evaluation of potential for confusion with other product names. If the FDA objects to any of our proposed proprietary product names, we may
be required to expend significant additional resources in an effort to identify a suitable substitute name that would qualify under applicable trademark laws,
not infringe the existing rights of third parties and be acceptable to the FDA.

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

Filing, prosecuting and defending patents on product candidates in all countries throughout the world would be prohibitively expensive, and our intellectual
property  rights  in  some  countries  outside  the  United  States  can  be  less  extensive  than  those  in  the  United  States.  In  addition,  the  laws  of  some  foreign
countries do not protect intellectual property rights to the same extent as federal and state laws in the United States. Consequently, we may not be able to
prevent  third  parties  from  practicing  our  inventions  in  all  countries  outside  the  United  States,  or  from  selling  or  importing  products  made  using  our
inventions in and into the United States or other jurisdictions. Potential competitors may use our technologies in jurisdictions where we have not obtained
patent protection to develop their own products and further, may export otherwise infringing products to territories where we have patent protection, but
enforcement is not as strong as that in the United States. These products may compete with our product candidates, if approved, and our patents or other
intellectual property rights may not be effective or sufficient to prevent them from competing.

Many companies have encountered significant problems in protecting and defending intellectual property rights in foreign jurisdictions. The legal systems
of  certain  countries,  particularly  certain  developing  countries,  do  not  favor  the  enforcement  of  patents,  trade  secrets  and  other  intellectual  property
protection, particularly those relating to biotechnology products, which could make it difficult for us to stop the infringement of our patents or marketing of
competing  products  in  violation  of  our  proprietary  rights  generally.  Proceedings  to  enforce  our  patent  rights  in  foreign  jurisdictions  could  result  in
substantial costs and divert our efforts and attention from other aspects of our business, could put our patents at risk of being invalidated or interpreted
narrowly and our patent applications at risk of not issuing and could provoke third parties to assert claims against us. We may not prevail in any lawsuits
that  we  initiate  and  the  damages  or  other  remedies  awarded,  if  any,  may  not  be  commercially  meaningful.  Accordingly,  our  efforts  to  enforce  our
intellectual property rights around the world may be inadequate to obtain a significant commercial advantage from the intellectual property that we develop
or license.

Under applicable employment laws, we may not be able to enforce covenants not to compete.

We generally enter into non-competition agreements with our employees. These agreements prohibit our employees, if they cease working for us, from
competing directly with us or working for our competitors or clients for a limited period. We may be unable to enforce these agreements under the laws of
the  jurisdictions  in  which  our  employees  work  and  it  may  be  difficult  for  us  to  restrict  our  competitors  from  benefitting  from  the  expertise  our  former
employees  or  consultants  developed  while  working  for  us.  For  example,  Israeli  labor  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 protection of a company’s trade secrets or other intellectual property.

Risks Related to Ownership of Our Ordinary Shares

The market price of our ordinary shares may be highly volatile, and you may not be able to resell your shares at the purchase price.

An active trading market for our ordinary shares may not be available. You may not be able to sell your shares quickly or at the market price if trading in
our ordinary shares is not active.

The market price of our ordinary shares has been and is likely to remain volatile. Our share price could be subject to wide fluctuations in response to a
variety of factors, including the following:

●

●

●

adverse results or delays in preclinical studies or clinical trials, and resulting changes in our clinical development programs;

reports of adverse events in other similar products or clinical trials of such products;

inability to obtain additional funding;

any delay in filing an IND or BLA for any of our product candidates and any adverse development or perceived adverse development with respect
to the FDA’s review of that IND or BLA;

failure to  develop  successfully  and  commercialize  our  product  candidates  for  the  proposed  indications  and  future  product  candidates  for  other
indications or new candidates;

failure to maintain our licensing arrangements or enter into strategic collaborations;

failure by us or our licensors and strategic collaboration partners to prosecute, maintain or enforce our intellectual property rights;

changes in laws or regulations applicable to future products;

inability to scale up our manufacturing capabilities (including in Israel), inability to obtain adequate product supply for our product candidates or
the inability to do so at acceptable prices;

adverse regulatory decisions, including by the IIA under the Research Law;

introduction of new products, services or technologies by our competitors;

failure to meet or exceed financial projections we may provide to the public;

failure to meet or exceed the financial expectations of the investment community;

the perception of the pharmaceutical industry by the public, legislatures, regulators and the investment community;

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

disputes or other developments relating to proprietary rights, including patents, litigation matters and our ability to obtain patent protection for our
technologies;

additions or departures of key scientific or management personnel;

significant lawsuits, including patent or shareholder litigation;

changes in the market valuations of similar companies;

sales of our ordinary shares by us or our shareholders in the future; and

trading volume of our ordinary shares.

In addition, companies trading in the stock market in general, and biopharmaceutical companies in particular, have experienced extreme price and volume
fluctuations that have often been unrelated or disproportionate to the operating performance of these companies. Broad market and industry factors may
negatively affect the market price of our ordinary shares, regardless of our actual operating performance.

There has been limited trading volume for our ordinary shares.

Even though our ordinary shares have been listed on the NASDAQ Global Market, there has been limited liquidity in the market for the ordinary shares,
which could make it more difficult for holders to sell their ordinary shares. There can be no assurance that an active trading market for our ordinary shares
will  be  sustained.  In  addition,  the  stock  market  generally  has  experienced  extreme  price  and  volume  fluctuations  that  have  often  been  unrelated  or
disproportionate  to  the  operating  performance  of  listed  companies.  Broad  market  and  industry  factors  may  negatively  affect  the  market  price  of  our
ordinary shares, regardless of our actual operating performance. The market price and liquidity of the market for our ordinary shares that will prevail in the
market may be higher or lower than the price you pay and may be significantly affected by numerous factors, some of which are beyond our control.

Our principal shareholders and management own a significant percentage of our shares and will be able to exert significant control over matters
subject to shareholder approval.

As of December 31, 2020, to the best of our information, our executive officers, directors, five percent shareholders and their affiliates beneficially owned
approximately  30.5%  of  our  voting  shares.  Therefore,  these  shareholders  have  the  ability  to  control  us  through  their  ownership  positions.  These
shareholders may be able to determine all matters requiring shareholder approval. For example, these shareholders, if they were to act together, may be able
to  control  elections  of  directors,  amendments  of  our  organizational  documents,  or  approval  of  any  merger,  sale  of  assets,  or  other  major  corporate
transaction. This may prevent or discourage unsolicited acquisition proposals or offers for our ordinary shares that you may believe are in your best interest
as one of our shareholders.

Our ordinary shares are subject to substantial dilution in their book value.

As of December 31, 2020, options, RSUs and warrants to purchase 23,264,072 ordinary shares at a weighted average exercise price of $2.38 per share were
outstanding. The exercise of any of these options and warrants would result in additional dilution.

Sales of a substantial number of our ordinary shares in the public market could cause our share price to fall.

If our existing shareholders sell, indicate an intention to sell or the market perceives that they intend to sell, substantial amounts of our ordinary shares in
the public market, the market price of our ordinary shares could decline significantly. As of December 31, 2020, we had outstanding a total of 48,187,463
ordinary shares. Substantially all of the shares are available for sale in the public market.

As  of  December  31,  2020,  14,678,180  ordinary  shares  are  held  by  directors,  executive  officers  and  other  affiliates  (holders  of  more  than  10%  of  the
Company’s share capital) and are subject to Rule 144 under the Securities Act of 1933, as amended, or the Securities Act.

In addition, as of March 1, 2021, an aggregate of 15,009,831 ordinary shares that are either subject to outstanding options, reserved for future issuance
under our 2014 Plan or subject to outstanding warrants will or may become eligible for sale in the public market to the extent permitted by the provisions of
various vesting schedules and Rule 144 and Rule 701 under the Securities Act. If these additional ordinary shares are sold, or if it is perceived that they will
be sold, in the public market, the market price of our ordinary shares could decline.

Future sales and issuances of our ordinary shares or rights to purchase ordinary shares, including pursuant to our equity incentive plans, could
result in additional dilution of the percentage ownership of our shareholders and could cause our share price to fall.

Additional capital will be needed in the future to continue our planned operations. To the extent we raise additional capital by issuing equity securities, our
shareholders may experience substantial dilution. We may sell ordinary shares, convertible securities or other equity securities in one or more transactions
at  prices  and  in  a  manner  we  determine  from  time  to  time.  If  we  sell  ordinary  shares,  convertible  securities  or  other  equity  securities  in  more  than  one
transaction, investors may be materially diluted by subsequent sales. These sales may also result in material dilution to our existing shareholders, and new
investors could gain rights superior to our existing shareholders.

Pursuant  to  our  Employee  Share  Ownership  and  Option  Plan  (2014),  or  the  2014  Plan,  our  management  is  authorized  to  grant  share  options  and  other
equity-based awards to our employees, directors and consultants. Currently, we plan to register the increased number of shares available for issuance under
the 2014 Plan each year. If our board of directors elects to increase the number of shares available for future grant by the maximum amount each year, our
shareholders may experience additional dilution, which could cause our share price to fall.

We could be subject to securities class action litigation.

In the past, securities class action litigation has often been brought against a company following a decline in the market price of its securities. This risk is
especially relevant for us because pharmaceutical companies have experienced significant share price volatility in recent years. For example, the price of
our ordinary shares, which reached its high record of $17.02 per share at the close of the trading on January 27, 2015, decreased as low as $2.8 per share at
the close of the trading on February 1, 2016 a drop of about 84%. In addition, the price of our ordinary shares, which was $6.80 per share at the close of the
trading on March 7, 2018, decreased to $2.65 per share at the close of the trading on March 8, 2018 and to its low record of $0.6 per share at the close of
the trading on December 21, 2018. If we face such litigation, it could result in substantial costs and a diversion of management’s attention and resources,
which could harm our business.

We do not intend to pay dividends on our ordinary shares in the foreseeable future, so any returns will be limited to the value of our shares.

We have never declared or paid any cash dividends on our share capital. We currently anticipate that we will retain future earnings for the development,
operation and expansion of our business and do not anticipate declaring or paying any cash dividends for the foreseeable future. Any return to shareholders
will therefore be limited to the appreciation of their shares. In addition, Israeli law limits our ability to declare and pay dividends, and may subject our
dividends to Israeli withholding taxes. Furthermore, our payment of dividends (out of tax- exempt income) may retroactively subject us to certain Israeli
corporate income taxes, to which we would not otherwise be subject.

If  equity  research  analysts  do  not  publish  research  reports  about  our  business  or  if  they  issue  unfavorable  commentary  or  downgrade  our
ordinary shares, the price of our ordinary shares could decline.

The trading market for our ordinary shares relies in part on the research and reports that equity research analysts publish about us and our business. The
price of our ordinary shares could decline if we do not obtain research analyst coverage, or one or more securities analysts downgrade our ordinary shares
or if those analysts issue other unfavorable commentary or cease publishing reports about us or our business.

Risks Related to Our Incorporation and Operations in Israel

We are a “foreign private issuer” and intend to follow certain home country corporate governance practices, and our shareholders may not have
the same protections afforded to shareholders of companies that are subject to all NASDAQ corporate governance requirements. Additionally, we
cannot be certain if the reduced disclosure requirements applicable to our status as a foreign private issuer, will make our ordinary shares less
attractive to investors.

As a foreign private issuer, we are permitted, and intend, to follow certain home country corporate governance practices instead of those otherwise required
under the NASDAQ Stock Market for domestic U.S. issuers. For instance, we intend to follow home country practice in Israel with regard to the quorum
requirement  for  shareholder  meetings.  As  permitted  under  the  Israeli  Companies  Law,  5759-1999,  or  the  Companies  Law,  our  articles  of  association
provide  that  the  quorum  for  any  meeting  of  shareholders  shall  be  the  presence  of  at  least  two  shareholders  present  in  person,  by  proxy  or  by  a  voting
instrument, who hold at least 25% of the voting power of our shares instead of the 33 1/3% of the issued share capital requirement. We may in the future
elect  to  follow  home  country  practices  in  Israel  (and  consequently  avoid  the  requirements  that  would  otherwise  apply  to  a  U.S.  company  listed  on  The
NASDAQ Global Market) with regard to other matters, as well, such as the formation of compensation, nominating and governance committees, separate
executive sessions of independent directors and non-management directors and the requirement to obtain shareholder approval for certain dilutive events
(such as for the establishment or amendment of certain equity-based compensation plans, issuances that will result in a change of control of the company,
certain transactions other than a public offering involving issuances of a 20% or more interest in the company and certain acquisitions of the stock or assets
of another company). Following our home country governance practices as opposed to the requirements that would otherwise apply to a U.S. company
listed  on  The  NASDAQ  Global  Market  may  provide  less  protection  to  you  than  what  is  accorded  to  investors  under  the  NASDAQ  Stock  Market  rules
applicable to domestic U.S. issuers. See “Item 16G. Corporate Governance” for more information.

In addition, as a foreign private issuer, we are exempt from the rules and regulations under the Exchange Act related to the furnishing and content of proxy
statements,  including  with  regards  to  compensation  of  executive  officers  and  our  officers,  directors  and  principal  shareholders  we  are  exempt  from  the
reporting  and  the  short-swing  profit  recovery  provisions  contained  in  Section  16  of  the  Exchange  Act.  We  are  also  permitted  to  disclose  limited
compensation information for our executive officers on an individual basis and we are generally exempt from filing quarterly reports with the SEC under
the Exchange Act. A recent amendment to regulations under the Israeli Companies Law requires us to disclose in the notice for our annual meeting of
shareholders, the annual compensation of our five most highly compensated officers on an individual, rather than aggregate, basis. However, this disclosure
is not as extensive as that required of a U.S. domestic issuer.

Further, we are not required under the Exchange Act to file annual and current reports and financial statements with the SEC as frequently or as promptly
as U.S. domestic companies whose securities are registered under the Exchange Act. Moreover, we are not required to comply with Regulation FD, which
restricts  the  selective  disclosure  of  material  nonpublic  information  to,  among  others,  broker-dealers  and  holders  of  a  company’s  securities  under
circumstances in which it is reasonably foreseeable that the holder will trade in the company’s securities on the basis of the information. These exemptions
and leniencies reduce the frequency and scope of information and protections to which you may otherwise have been eligible in relation to a U.S. domestic
issuer.

We  would  lose  our  foreign  private  issuer  status  if  a  majority  of  our  directors  or  executive  officers  are  U.S.  citizens  or  residents  and  we  fail  to  meet
additional  requirements  necessary  to  avoid  loss  of  foreign  private  issuer  status.  Although  we  have  elected  to  comply  with  certain  U.S.  regulatory
provisions, our loss of foreign private issuer status would make such provisions mandatory. The regulatory and compliance costs to us under U.S. securities
laws as a U.S. domestic reporting company may be significantly higher. If we are not a foreign private issuer, we will be required to file periodic reports
and registration statements on U.S. domestic reporting company forms with the SEC, which are more detailed and extensive than the forms available to a
foreign private issuer. We may be required to modify certain of our policies to comply with accepted governance practices associated with U.S. domestic
reporting companies. Such conversion and modifications will involve additional costs. In addition, we may lose our ability to rely upon exemptions from
certain corporate governance requirements on U.S. stock exchanges that are available to foreign private issuers.

We cannot predict if investors will find our ordinary shares less attractive because we may rely on these reduced requirements. If some investors find our
ordinary shares less attractive as a result, there may be a less active trading market for our ordinary shares and our share price may be more volatile.

Potential political, economic and military instability in the State of Israel, where the majority of our senior management and our research and
development facilities are located, may adversely affect our results of operations.

We are incorporated under Israeli law and our offices and operations are located in the State of Israel. In addition, our key employees, officers and all but
two of our directors are residents of Israel. Accordingly, political, economic and military conditions in Israel directly affect our business. Since the State of
Israel was established in 1948, a number of armed conflicts have occurred between Israel and its neighboring countries.

Any hostilities involving Israel or the interruption or curtailment of trade between Israel and its present trading partners, or a significant downturn in the
economic or financial condition of Israel, could affect adversely our operations. Since October 2000, there have been increasing occurrences of terrorist
violence.  Ongoing  and  revived  hostilities  or  other  Israeli  political  or  economic  factors  could  harm  our  operations,  product  development  and  results  of
operations.

Although Israel has entered into various agreements with Egypt, Jordan and the Palestinian Authority, there has been an increase in unrest and terrorist
activity, which began in October 2000 and has continued with varying levels of severity. The establishment in 2006 of a government in the Palestinian
Authority by representatives of the Hamas militant group has created additional unrest and uncertainty in the region. In 2006, a conflict between Israel and
the  Hezbollah  in  Lebanon  resulted  in  thousands  of  rockets  being  fired  from  Lebanon  up  to  50  miles  into  Israel.  Starting  in  December  2008,  for
approximately three weeks, Israel engaged in an armed conflict with Hamas in the Gaza Strip, which involved missile strikes against civilian targets in
various parts of Israel and negatively affected business conditions in Israel. In November 2012, for approximately one week, Israel experienced a similar
armed  conflict,  resulting  in  hundreds  of  rockets  being  fired  from  the  Gaza  Strip  and  disrupting  most  day-to-day  civilian  activity  in  southern  Israel.
Beginning in July 2014, for approximately seven weeks, Israel experienced additional armed conflict between Israel and Hamas, which included rocket
strikes against civilian targets in various parts of Israel. If renewed, these hostilities may negatively affect business conditions in Israel. In addition, Israel
faces threats from more distant neighbors, in particular, Iran. Our insurance policies do not cover us for the damages incurred in connection with these
conflicts  or  for  any  resulting  disruption  in  our  operations.  The  Israeli  government,  as  a  matter  of  law,  provides  coverage  for  the  reinstatement  value  of
direct damages that are caused by terrorist attacks or acts of war; however, the government may cease providing such coverage or the coverage might not
be enough to cover potential damages. In the event that hostilities disrupt the ongoing operation of our facilities or the airports and seaports on which we
depend to import and export our supplies and products, our operations may be materially adversely affected.

In addition, since the end of 2010, numerous acts of protest and civil unrest have taken place in several countries in the Middle East and North Africa,
many of which involved significant violence. The civil unrest in Egypt, which borders Israel, resulted in the resignation of its president Hosni Mubarak,
and to significant changes to the country’s government. In Syria, also bordering Israel, a civil war is continuing to take place. The ultimate effect of these
developments on the political and security situation in the Middle East and on Israel’s position within the region is not clear at this time. Such instability
may lead to deterioration in the political and trade relationships that exist between the State of Israel and certain other countries.

Popular uprisings in various countries in the Middle East and North Africa are affecting the political stability of those countries. Such instability may lead
to deterioration in the political and trade relationships that exist between the State of Israel and these countries. Several countries, principally in the Middle
East,  still  restrict  doing  business  with  Israel  and  Israeli  companies,  and  additional  countries  may  impose  restrictions  on  doing  business  with  Israel  and
Israeli companies if hostilities in Israel or political instability in the region continues or increases. Any hostilities involving Israel or the interruption or
curtailment  of  trade  between  Israel  and  its  present  trading  partners,  or  significant  downturns  in  the  economic  or  financial  condition  of  Israel,  could
adversely  affect  our  operations  and  product  development  and  adversely  affect  our  share  price.  Similarly,  Israeli  companies  are  limited  in  conducting
business with entities from several countries. For instance, in 2008, the Israeli legislature passed a law forbidding any investments in entities that transact
business with Iran.

Our operations may be disrupted by the obligations of personnel to perform military service.

As of March 1, 2021, we had 38 employees, all of whom were based in Israel. Some of our employees may be called upon to perform up to 36 days (and in
some cases more) of annual military reserve duty until they reach the age of 40 (and in some cases, up to 45 or older) and, in emergency circumstances,
could be called to immediate and unlimited active duty. In the event of severe unrest or other conflict, individuals could be required to serve in the military
for  extended  periods  of  time.  Since  September  2000,  in  response  to  increased  tension  and  hostilities,  there  have  been  occasional  call-ups  of  military
reservists,  including  in  connection  with  the  2006  conflict  in  Lebanon,  and  the  December  2008,  November  2012  and  July-August  2014  conflicts  with
Hamas, and it is possible that there will be additional call-ups in the future. Our operations could be disrupted by the absence of a significant number of our
employees related to military service or the absence for extended periods of one or more of our key employees for military service. Such disruption could
materially  adversely  affect  our  business  and  results  of  operations.  Additionally,  the  absence  of  a  significant  number  of  the  employees  of  our  Israeli
suppliers and contractors related to military service or the absence for extended periods of one or more of their key employees for military service may
disrupt their operations.

The tax benefits that are available to us if and when we generate taxable income require us to meet various conditions and may be prevented or
reduced in the future, which could increase our costs and taxes.

If and when we generate taxable income, we would be eligible for certain tax benefits provided to “Benefited Enterprises” under the Israeli Law for the
Encouragement  of  Capital  Investments,  1959,  as  amended,  or  the  Investment  Law.  In  order  to  remain  eligible  for  the  tax  benefits  for  “Benefited
Enterprises” we must continue to meet certain conditions stipulated in the Investment Law and its regulations, as amended. In addition, we informed the
Israeli Tax Authority of our choice of 2012 as a “Benefited Enterprise” election year, all under the Investment Law. The benefits available to us under this
tax  regulation  are  subject  to  the  fulfillment  of  conditions  stipulated  in  the  regulation.  Further,  in  the  future  these  tax  benefits  may  be  reduced  or
discontinued. If these tax benefits are reduced, cancelled or discontinued, our Israeli taxable income would be subject to regular Israeli corporate tax rates.
The standard corporate tax rate for Israeli companies is 23% for 2018 and thereafter. Additionally, if we increase our activities outside of Israel through
acquisitions, for example, our expanded activities might not be eligible for inclusion in future Israeli tax benefit programs. See “Item 10E. Taxation-Israeli
Tax Considerations and Government Programs-Law for the Encouragement of Capital Investments, 5719-1959.”

It may be difficult to enforce a U.S. judgment against us, our officers and directors and the Israeli experts named in this prospectus in Israel or the
United States, or to assert U.S. securities laws claims in Israel or serve process on our officers and directors and these experts.

We were incorporated in Israel, and our corporate headquarters and substantially all of our operations are located in Israel. All of our executive officers and
all but two of our directors, and the Israeli experts named in this prospectus, are located in Israel. The majority of our assets and the assets of these persons
are located outside the United States. Therefore, it may be difficult for an investor, or any other person or entity, to enforce a U.S. court judgment based
upon the civil liability provisions of the U.S. federal securities laws against us or any of these persons in a U.S. or Israeli court, or to effect service of
process upon these persons in the United States. Additionally, it may be difficult for an investor, or any other person or entity, to assert U.S. securities law
claims in original actions instituted in Israel. Israeli courts may refuse to hear a claim based on an alleged violation of U.S. securities laws against us or our
officers and directors on the grounds that Israel is not the most appropriate forum in which to bring such a claim. Even if an Israeli court agrees to hear a
claim, it may determine that Israeli law and not U.S. law is applicable to the claim. If U.S. law is found to be applicable, the content of applicable U.S. law
must be proved as a fact, which can be a time-consuming and costly process. Certain matters of procedure will also be governed by Israeli law. There is
little binding case law in Israel addressing the matters described above.

Your  rights  and  responsibilities  as  our  shareholder  will  be  governed  by  Israeli  law,  which  may  differ  in  some  respects  from  the  rights  and
responsibilities of shareholders of U.S. corporations.

Since we are incorporated under Israeli law, the rights and responsibilities of our shareholders are governed by our articles of association and Israeli law.
These rights and responsibilities differ in some material respects from the rights and responsibilities of shareholders of U.S. corporations. In particular, a
shareholder of an Israeli company has a duty to act in good faith and in a customary manner in exercising its rights and performing its obligations towards
the company and other shareholders and to refrain from abusing its power in the company, including, among other things, in voting at the general meeting
of shareholders on certain matters, such as an amendment to the company’s articles of association, an increase of the company’s authorized share capital, a
merger of the company and approval of related party transactions that require shareholder approval. A shareholder also has a general duty to refrain from
discriminating against other shareholders. In addition, a controlling shareholder or a shareholder who knows that it possesses the power to determine the
outcome of a shareholder vote or to appoint or prevent the appointment of an officer of the company has a duty to act in fairness towards the company with
regard to such vote or appointment. However, Israeli law does not define the substance of this duty of fairness. There is limited case law available to assist
us in understanding the nature of this duty or the implications of these provisions. These provisions may be interpreted to impose additional obligations and
liabilities  on  our  shareholders  that  are  not  typically  imposed  on  shareholders  of  U.S.  corporations.  See  “Item  6.  Directors,  Senior  Management  and
Employees-Approval of Related Party Transactions Under Israeli Law-Shareholders’ Duties.”

Provisions  of  Israeli  law  and  our  amended  and  restated  articles  of  association  could  make  it  more  difficult  for  a  third  party  to  acquire  us  or
increase the cost of acquiring us, even if doing so would benefit our shareholders.

Israeli  law  regulates  mergers,  requires  tender  offers  for  acquisitions  of  shares  above  specified  thresholds,  requires  special  approvals  for  transactions
involving directors, officers or significant shareholders and regulates other matters that may be relevant to such types of transactions. For example, a tender
offer for all of a company’s issued and outstanding shares can only be completed if the acquirer receives positive responses from the holders of at least 95%
of the issued share capital. Completion of the tender offer also requires approval of a majority of the offerees that do not have a personal interest in the
tender  offer,  unless  at  least  98%  of  the  company’s  outstanding  shares  are  tendered.  Furthermore,  the  shareholders,  including  those  who  indicated  their
acceptance of the tender offer (unless the acquirer stipulated in its tender offer that a shareholder that accepts the offer may not seek appraisal rights), may,
at any time within six months following the completion of the tender offer, petition an Israeli court to alter the consideration for the acquisition. See “Item
10B. Memorandum and Articles of Association-Acquisitions under Israeli Law” for additional information.

Further, Israeli tax considerations may make potential transactions undesirable to us or to some of our shareholders whose country of residence does not
have  a  tax  treaty  with  Israel  granting  tax  relief  to  such  shareholders  from  Israeli  tax.  For  example,  Israeli  tax  law  does  not  recognize  tax-free  share
exchanges to the same extent as U.S. tax law. With respect to mergers, Israeli tax law allows for tax deferral in certain circumstances but makes the deferral
contingent on the fulfillment of a number of conditions, including, in some cases, a holding period of two years from the date of the transaction during
which  sales  and  dispositions  of  shares  of  the  participating  companies  are  subject  to  certain  restrictions.  Moreover,  with  respect  to  certain  share  swap
transactions, the tax deferral is limited in time, and when such time expires, the tax becomes payable even if no disposition of the shares has occurred.

Certain U.S. shareholders may be subject to adverse tax consequences if we are characterized as “Controlled Foreign Corporation.”

Each “Ten Percent Shareholder” in a non-U.S. corporation that is classified as a “controlled foreign corporation,” or a CFC, for U.S. federal income tax
purposes generally is required to include in income for U.S. federal tax purposes such Ten Percent Shareholder’s pro rata share of the CFC’s “Subpart F
income” and investment of earnings in U.S. property, even if the CFC has made no distributions to its shareholders. A non-U.S. corporation generally will
be  classified  as  a  CFC  for  U.S.  federal  income  tax  purposes  if  Ten  Percent  Shareholders  own,  directly  or  indirectly,  more  than  50%  of  either  the  total
combined voting power of all classes of stock of such corporation entitled to vote or of the total value of the stock of such corporation. A “Ten Percent
Shareholder” is a U.S. person (as defined by the U.S. Internal Revenue Code of 1986, as amended), who owns or is considered to own 10% or more of the
total  combined  voting  power  of  all  classes  of  stock  entitled  to  vote  of  such  corporation.  The  determination  of  CFC  status  is  complex  and  includes
attribution rules, the application of which is not entirely certain.

We  do  not  believe  that  we  were  a  CFC  for  the  taxable  year  ended  December  31,  2019  or  that  we  are  currently  a  CFC.  It  is  possible,  however,  that  a
shareholder treated as a U.S. person for U.S. federal income tax purposes will acquire, directly or indirectly, enough shares to be treated as a Ten Percent
Shareholder after application of the constructive ownership rules and, together with any other Ten Percent Shareholders of our company, cause us to be
treated as a CFC for U.S. federal income tax purposes. We believe that certain of our shareholders are Ten Percent Shareholders for U.S. federal income tax
purposes. Holders should consult their own tax advisors with respect to the potential adverse U.S. federal income tax consequences of becoming a Ten
Percent Shareholder in a CFC.

We might be classified as a passive foreign investment company in future years, and our U.S. shareholders may suffer adverse tax consequences as
a result.

Generally, if, for any taxable year, at least 75% of our gross income is passive income, or at least 50% of the value of our assets is attributable to assets that
produce  passive  income  or  are  held  for  the  production  of  passive  income,  including  cash,  we  would  be  characterized  as  a  passive  foreign  investment
company, or PFIC, for U.S. federal income tax purposes. For purposes of these tests, passive income includes dividends, interest, and gains from the sale or
exchange of investment property and rents and royalties other than rents and royalties which are received from unrelated parties in connection with the
active conduct of a trade or business. If we are characterized as a PFIC, our U.S. shareholders may suffer adverse tax consequences, including having gains
realized  on  the  sale  of  our  ordinary  shares  treated  as  ordinary  income,  rather  than  capital  gain,  the  loss  of  the  preferential  rate  applicable  to  dividends
received on our ordinary shares by individuals who are U.S. holders, and having interest charges apply to distributions by us and the proceeds of share
sales. See “Item 10E. Taxation-Certain Material U.S. Federal Income Tax Considerations-Passive Foreign Investment Company Considerations.”

Since PFIC status depends on the composition of our income and the composition and value of our assets (which may be determined in part by reference to
the market value of our ordinary shares, which may be volatile) from time to time, there can be no assurance that we will not be considered a PFIC for any
taxable year. We had no revenue-producing operations until and including table year 2016. We believe that we were not a PFIC for our 2017, 2018, 2019
and  2020  taxable  years.  In  addition,  unless  and  until  we  generate  sufficient  revenue  from  active  licensing  and  other  non-passive  sources  and  otherwise
satisfy the asset test above, we might be treated as a PFIC in future taxable years.

Capital Expenditures

For a discussion of our capital expenditures, see “Item 5. Operating and Financial Review and Prospects-Liquidity and Capital Resources.”

Business Overview

We are a clinical-stage biopharmaceutical company focused on the discovery, development and commercialization of first-in-class treatments for areas of
unmet  need  in  cancer  and  immune/inflammatory  indications.  We  have  developed  three  platform  technologies:  a  gene-therapy  based  technology  for
targeting newly formed blood vessels with focus on cancer, an antibody-based technology targeting MOSPD2 for immuno-oncology and anti-inflammatory
applications, and the Lecinoxoids, a family of small-molecules for chronic immune-related indications.

Our main program in oncology is based on our proprietary Vascular Targeting System, or VTS, platform technology, which we believe will allow us to
develop  product  candidates  for  multiple  oncology  indications.  The  VTS  technology  utilizes  genetically  targeted  therapy  to  destroy  newly  formed,  or
angiogenic, blood vessels. By utilizing a viral vector as a delivery mechanism, the VTS platform can also lead to induction or enhancement of a localized
anti-tumor immune response, thereby turning immunologically ‘cold’ tumors ‘hot’.

Our lead product candidate, VB-111 (ofranergene obadenovec), is a gene-based biologic that we are developing for solid tumor indications, and which we
have advanced to programs for ovarian cancer, recurrent glioblastoma, or rGBM, an aggressive form of brain cancer, and thyroid cancer. We have obtained
fast track designation for VB-111 in the United States for prolongation of survival in patients with glioblastoma that has recurred following treatment with
standard chemotherapy and radiation. We have also received orphan drug designation for GBM in both the United States and Europe. VB-111 has also
received an orphan designation for the treatment of ovarian cancer by the European Commission.

OVAL is our international Phase 3 randomized pivotal registration enabling clinical trial that compares a combination of VB-111 and paclitaxel to placebo
plus paclitaxel, in patients with platinum-resistant ovarian cancer. The study is planned to enroll 400 patients. In March 2020, we announced the outcome
of  the  planned  interim  analysis  in  the  OVAL  study.  The  OVAL  independent  Data  Safety  Monitoring  Committee  (DSMC)  reviewed  unblinded  data  and
assessed CA-125 response, measured according to the GCIG criteria, in the first 60 enrolled subjects evaluable for CA-125 analysis. The DSMC confirmed
that the study met the interim pre-specified efficacy criterion, of an absolute percentage advantage of 10% or higher CA-125 response rate for the VB-111
treatment  arm,  and  recommended  the  study  continue.  The  overall  response  rate  in  the  first  60  randomized  evaluable  patients  was  53%.  Assuming  a
balanced randomization, the response rate in the treatment arm (VB-111 in addition to weekly paclitaxel) was 58% or higher. In patients who had post-
dosing  fever,  which  is  a  marker  for  VB-111  treatment,  the  response  rate  was  69%.  Results  of  the  interim  analysis  were  published  in  a  peer-review
manuscript (Arend et al., Gynecol Oncol. 2021).

The  following  analysis  of  the  OVAL  study  was  conducted  in  August  2020.  The  DSMC  reviewed  unblinded  overall  survival  (OS)  data  of  the  first  100
enrolled subjects with a follow-up of at least 3 months. The committee also looked at response rate and safety information. The DSMC recommended that
the study continue as planned. The primary endpoint of the OVAL Phase 3 study is OS.

In February 2021, we announced the results of a subsequent DSMC pre-planned review of the OVAL study. The committee, which reviewed unblinded
data of about 200 patients, found no safety issues with the trial and recommended its continuation as planned. The next DSMC review in the OVAL study is
expected  in  the  third  quarter  of  2021.  Our  OVAL  study  is  being  conducted  in  collaboration  with  the  GOG  Foundation,  Inc.,  a  leading  organization  for
research excellence in the field of gynecologic malignancies.

Final results from our Phase 1/2 clinical trial of VB-111 for recurrent platinum-resistant ovarian cancer were reported in June 2019 and published online in
April 2020 (Arend et al., Gynecol Oncol. 2020). Data demonstrated a median OS of 498 days in the VB-111 therapeutic-dose arm, versus 172.5 days in the
low-dose arm (p=0.03). 58% of evaluable patients treated with the therapeutic dose of VB-111 had a GCIG CA-125 response. VB-111 activity signals were
seen despite unfavorable prognostic characteristics (48% platinum refractory disease and 52% previous treatment with anti-angiogenics). There was a trend
for favorable survival in patients who had CA-125 decrease >50% in the VB-111 therapeutic-dose arm (808 vs. 351 days; p=0.067) implicating CA-125 as
a potentially valuable biomarker for response to VB-111. Post treatment fever was also associated with a signal for improved survival (808 vs. 479 days;
p=0.27).

In a Phase 2 study for rGBM, patients who were primed with VB-111 monotherapy that was continued after progression with the addition of bevacizumab
(Avastin®)  showed  significant  survival  (414  vs  223  days;  HR  0.48;  p=0.043)  and  progression  free  survival  (PFS)  advantage  (90  vs  60  days;  HR  0.36;
p=0.032) compared to a cohort of patients that had limited exposure to VB-111 (Brenner et al., Neuro Oncol. 2019). Radiographic responders to VB-111
exhibited specific imaging characteristics related to its mechanism of action. Survival advantage was also seen in comparison to historic controls, with the
percentage of patients living more than one year doubling from 24% to 57%.

Our  Phase  3  GLOBE  study  in  rGBM  compared  upfront  concomitant  administration  of  VB-111,  without  priming,  and  bevacizumab  to  bevacizumab
monotherapy. The study, which enrolled a total of 256 patients in the US, Canada and Israel was conducted under a special protocol assessment, or SPA,
agreement  with  the  U.S.  Food  and  Drug  Administration,  or  FDA,  with  full  endorsement  by  the  Canadian  Brain  Tumor  Consortium  (CBTC).  In  this
modified regimen, the treatment did not improve overall survival (OS) and PFS outcomes in rGBM. Study results (Cloughesy et al. Neuro Oncol. 2019)
attribute the contradictory outcomes between the Phase 2 and Phase 3 trials as being related to the lack of VB-111 monotherapy priming in the GLOBE
study, providing clinical, mechanistic and radiographic support for this hypothesis. Notably, GLOBE data show improved outcomes associated with a post
VB-111 fever reaction, similar to outcomes from previous VB-111 studies, providing support that fever is a potential biomarker for better survival with
VB-111, secondary to the drug’s immunologic mechanism of action. No new safety concerns associated with VB-111 have been identified in the study. We
do not think that results of the GLOBE study will necessarily have implications on the prospects for VB-111 in other regimens or tumor types.

On March 1, 2021, we announced that patient dosing has been initiated in a Phase 2 clinical trial investigating VB-111 for the treatment of rGBM. The new
Phase 2 study, sponsored by Dana-Farber Cancer Institute in collaboration with a group of top neuro-oncology US medical centers, will investigate neo-
adjuvant and adjuvant treatment with VB-111 in rGBM patients undergoing a second surgery.

VB-111 is also being studied in combination with nivolumab, an anti-PD1 immune checkpoint inhibitor, in the treatment of metastatic colorectal cancer.
The study is being sponsored by the U.S. National Cancer Institute under a Cooperative Research and Development Agreement, or CRADA. The open
label exploratory Phase 2 study will investigate if priming with VB-111 can drive immune cells into the tumor and turn the colorectal tumors from being
immunologically “cold” to “hot.” Enrollment in this clinical trial started in September 2020. A preliminary readout in this study is expected in the first half
of 2021.

In  February  2017,  we  reported  full  data  from  our  exploratory  Phase  2  study  of  VB-111  in  recurrent,  iodine-resistant  differentiated  thyroid  cancer.  The
primary endpoint of the trial, defined as 6-month progression-free-survival (PFS-6) of 25%, was met with a dose response. Forty-seven percent of patients
in the therapeutic-dose cohort reached PFS-6, versus 25% in the sub-therapeutic cohort, both groups meeting the primary endpoint. An overall survival
benefit was seen, with a tail of more than 40% at 3.7 years for the therapeutic-dose cohort, similar to historical data for pazopanib (Votrient®), a tyrosine
kinase inhibitor; however, most patients in the VB-111 study had tumors that previously had progressed on pazopanib or other kinase inhibitors.

Over 300 patients were exposed to VB-111 in completed clinical trials and it has been observed to be well-tolerated. In December 2015, we have been
granted a US composition of matter patents that provides intellectual property protection for VB-111 in the US until October 2033 before any patent term
extension.

We are also conducting two parallel drug development programs that are exploring the potential of MOSPD2, a protein that we identified as a key regulator
of cell motility, as a therapeutic target for inflammatory diseases and cancer.

For inflammatory applications, we are developing classical antibodies that are designed to bind and block MOSPD2 on immune cells. Our data show that
MOSPD2, which is predominantly expressed on the surface of human monocytes, is essential for their migration. By inhibiting this protein, we seek to
block this migration of monocytes to sites of inflammation, and accordingly to reduce inflammation and tissue damage. We believe that antibodies targeting
MOSPD2 have potential for treatment of various inflammatory indications, and are advancing our lead preclinical candidate VB-601 through IND-enabling
studies. In September 2020, we announced the successful completion of a Type B pre-IND meeting with the FDA regarding our development plan for VB-
601. Toxicology studies for VB-601 are currently underway. Submission of an IND for the clinical development of VB-601 is expected to occur in the first
half of 2022.

For oncology applications, we are developing antibodies aimed to kill tumor cells, based on MOSPD2 as a target whose expression is induced in multiple
tumors. We found that MOSPD2 was detected in the majority of cancerous organs, including colon, esophagus, liver and breast, where MOSPD2 seems to
play a key role in cancer cell metastasis (Salem et al., Int J. Cancer 2019). Given the specificity of MOSPD2 expression and its highly elevated expression
in tumors, we believe MOSPD2 can serve as a novel target for immuno-oncology mediated therapy for cancer.

In  October  2020,  we  announced  that  the  European  Patent  Office  (EPO)  has  granted  Patents  #3328408  and  #3328401,  which  cover  VBL’s  proprietary
investigational anti-MOSPD2 monoclonal antibodies to treat inflammatory conditions and oncology conditions, respectively. The patents are expected to
provide protection for VBL’s MOSPD2 antibodies for inflammation and cancer, until at least July 2036.

We also have been conducting a program targeting anti-inflammatory diseases, based on the use of our Lecinoxoid platform technology. Lecinoxoids are a
novel  class  of  small  molecules  we  developed  that  are  structurally  and  functionally  similar  to  naturally  occurring  molecules  known  to  modulate
inflammation.  The  lead  product  candidate  from  this  program,  VB-201,  is  a  Phase  2-stage  molecule  that  demonstrated  activity  in  reducing  vascular
inflammation in a Phase 2 sub-study in psoriatic patients with cardiovascular risk.

In January 2021, we announced the dosing of the first patient in a randomized controlled Phase 2 study of VB-201 for the treatment of COVID-19. The
study will assess the ability of VB-201 to prevent clinical deterioration and reduce morbidity and mortality in patients with severe COVID-19. Based on
recent preclinical studies, we also believe that VB-201 and some second generation molecules such as VB-703 may have potential applicability for NASH
and renal fibrosis.

In  October  2017,  we  announced  the  opening  of  our  new  gene  therapy  pharmaceutical  grade  manufacturing  plant  in  Modi’in,  Israel.  The  facility  was
established to support the commercial supply of VB-111 for the first indication, if approved. The Modi’in facility is the first commercial-scale gene therapy
manufacturing  facility  in  Israel  (20,000  sq.  ft.).  In  July  2019,  our  facility  was  certified  by  a  European  Union  (EU)  Qualified  Person  (QP)  as  being  in
compliance with EU Good Manufacturing Practices (GMP). In November 2019 our facility was awarded by the Israeli Ministry of Health the Certificate of
GMP Compliance of a Manufacturer.

In November 2017, we signed an exclusive license agreement with NanoCarrier Co., Ltd. (TSE Mothers:4571) for the development, commercialization,
and supply of VB-111 in Japan. VBL retains rights to VB-111 in the rest of the world. Under terms of the agreement, VBL has granted NanoCarrier an
exclusive license to develop and commercialize VB-111 in Japan for all indications. VBL will supply NanoCarrier with VB-111, and NanoCarrier will be
responsible for all regulatory and other clinical activities necessary for commercialization in Japan. Under the agreement, VBL is entitled to receive greater
than $100 million in development and commercial milestone payments, in addition to tiered royalties on net sales in the high-teens.

In  March  2019,  we  executed  an  exclusive  option  license  agreement  with  an  animal  health  company  for  the  development  of  our  proprietary  anti-
inflammatory molecule, VB-201, for veterinary use. We retain VB-201 rights for treatment of humans worldwide. Under the terms of the agreement, we
have granted an exclusive option license to explore the potential of VB-201 for animal health indications. In consideration, we received an undisclosed up-
front payment, and are entitled to receive additional development milestone payments. In April 2020, another milestone event under this agreement was
reached,  following  which  we  received  an  undisclosed  payment.  If  the  option  to  license  would  be  exercised,  we  will  receive  additional  milestones  and
royalties on net sales.

In January 2021, we announced that we entered into an Ordinary Share Purchase Agreement with Aspire Capital Fund, LLC. Under the Agreement, Aspire
has committed to purchase up to $20 million of our ordinary shares at our discretion from time to time during a 30-month period at prices based on the
market price at the time of each sale. We will retain full control as to the timing and amount of any sale of ordinary shares to Aspire, subject to certain
limitations specified in the Purchase Agreement. There are no warrants or other derivative securities associated with the transaction. We have the right to
terminate the Purchase Agreement at any time without any additional cost or penalty.

Our Strategy

Our goal is to become a leading biopharmaceutical company focused on discovering, developing and commercializing innovative therapeutics that leverage
our proprietary technologies for oncology and immune/inflammatory indications. We intend to achieve this goal by pursuing the following strategies:

●

Pursue regulatory approval for our lead oncology drug candidate, VB-111

We  believe  VB-111  has  the  potential  for  applications  in  various  solid  tumors.  Currently,  our  focus  is  on  development  of  VB-111  for  platinum-resistant
ovarian  cancer.  We  launched  the  OVAL  Phase  3  registration-enabling  study  for  this  indication  in  December  2017  and  we  expect  to  complete  patient
enrollment  at  the  end  of  2021  or  in  early  2022.  OVAL  is  an  event-driven  study.  We  intend  to  advance  VB-111  to  additional  cancer  indications,  either
independently or through investigator-sponsored studies or strategic collaborations.

Based on the understanding that study regimen may be a key factor for VB-111 activity in rGBM, we believe the outcome of the GLOBE study will not
necessarily have implications on the prospects for VB-111 in other regimens or tumor types. In March 2021, we announced that patient dosing has been
initiated  in  a  Phase  2  clinical  trial  investigating  VB-111  for  the  treatment  of  rGBM.  The  Phase  2  study,  sponsored  by  Dana-Farber  Cancer  Institute  in
collaboration with a group of top neuro-oncology US medical centers, will investigate neo-adjuvant and adjuvant treatment with VB-111 in rGBM patients
undergoing a second surgery.

Similarly,  in  February  2020,  we  announced  the  launch  of  a  Phase  2  clinical  trial  of  VB-111  in  combination  with  nivolumab  (Opdivo®),  an  immune
checkpoint inhibitor, in the treatment of metastatic colorectal cancer, under a Cooperative Research and Development Agreement (CRADA) between VBL
and the National Cancer Institute (NCI). We also conducted Phase 2 clinical trial of VB-111 in thyroid cancer, with positive results.

●

Selectively enter into licensing and collaboration arrangements to supplement our internal development capabilities

As  we  advance  our  pipeline  of  anti-cancer  product  candidates,  we  will  evaluate  opportunities  to  selectively  form  collaborative  alliances  for  our  non-
oncology assets, such as the Lecinoxoids platform or the MOSPD2 mAbs for inflammation, to expand our capabilities and accelerate the development and
commercialization of our oncology products. Accordingly, in March 2019, we announced a strategic exclusive option license agreement with one of the
world-leading European animal health companies, for the development of VB-201 for veterinary use. We retain the VB-201 rights for treatment of humans,
worldwide,  as  well  as  the  global  rights  for  other  Lecinoxoids  and  VB-600  candidates.  We  engage  in  conversations  with  third  parties  to  evaluate  such
potential collaborations on an ongoing basis.

●

Expand our manufacturing capacity to support clinical trials and possible commercialization of VB-111

We previously manufactured clinical quantities of VB-111 at our facility in Or-Yehuda, Israel and through a third party in the United States. In October
2017, we announced the opening of our new gene therapy manufacturing plant in Modi’in, Israel. In July 2019, our facility was certified by a European
Union (EU) Qualified Person (QP) as being in compliance with EU Good Manufacturing Practices (GMP). This plant can be the first commercial facility
for  production  of  VB-111  if  it  receives  regulatory  approval.  On  the  longer  term,  we  intend  to  have  more  than  one  manufacturing  site  for  VB-111,  if
regulatory approved.

Our Product Candidates and Technology

The following table summarizes the status of pipeline:

Our VTS Platform

Overview

Our  innovative,  proprietary  VTS  platform  technology  enables  systemic  administration  of  gene  therapy  to  either  destroy  or  promote  angiogenic  blood
vessels. VTS is both tissue- and condition-specific, allowing for targeted and limited gene expression in endothelial cells, the thin layer of cells that lines
the interior surface of blood vessels undergoing angiogenesis.

Our VTS platform technology comprises three components, a viral vector, a promoter and a transgene:

1. Viral vector - a modified virus that is used as a delivery vehicle to distribute the promoter and the transgene throughout the body.

2. Promoter - our proprietary, genetically modified promoter, called PPE-1-3X, that specifically targets the endothelial cells of angiogenic blood vessels.
When present in these cells, the promoter initiates the expression of the transgene.

3. Transgene - a genetic sequence designed to yield a specific biologic effect, the expression of which is directed by PPE-1-3X. The particular transgene
will vary depending on the therapeutic objectives of the product candidate.

Once the gene therapy has reached the angiogenic blood vessels, the PPE-1-3X promoter activates expression of the transgene to produce a desired RNA or
protein in the endothelial cells of those vessels. For oncology applications, the transgene selected is designed to destroy angiogenic blood vessels that feed
solid  tumors.  For  other  potential  applications,  such  as  the  treatment  of  ischemia,  a  different  transgene  can  be  selected  that  is  designed  to  promote  the
development of angiogenic blood vessels instead of their destruction.

VB-111 (ofranergene obadenovec)

VB-111 is a unique biologic agent that uses a dual mechanism to target solid tumors. Its mechanism combines blockade of tumor vasculature with an anti-
tumor immune response.

Based  on  a  non-integrating,  non-replicating,  Adeno  5  vector,  VB-111  utilizes  our  proprietary  Vascular  Targeting  System  (VTS)  to  target  the  tumor
vasculature for cancer therapy. We designed VB-111 to address oncology indications, specifically solid tumors, by selectively targeting the blood vessels
required  for  tumor  growth  and  encouraging  the  programmed  cell-death  process,  or  apoptosis,  of  cells  in  those  blood  vessels.  VB-111  is  administered
intravenously.  PPE-1-3X  is  activated  specifically  in  angiogenic  endothelial  cells  and  regulates  a  transgene  consisting  of  a  combination  of  two  gene
sequences known as Fas and TNFR1. When expressed, the transgene produces a unique pro-apoptotic protein, the Fas-TNFR1 chimera, that interacts with
a native inflammatory molecule, Tumor Necrosis Factor, or TNF-alpha, and results in the destruction of newly formed or immature blood vessels. When
activated by PPE-1-3X, specifically in angiogenic endothelial cells, this combination enables VB-111 to reduce tumor growth in a highly targeted manner.

In addition, VB-111 induces a specific anti-tumor immune response. The immunologic mechanism-of-action of viral-mediated anti-cancer therapies takes
advantage  of  the  natural  interplay  of  viruses  with  the  immune  system  and  the  ability  of  viruses  to  ‘kick-start’  immune  reactions.  In  response  to  viral
infection,  cells  within  the  tumor  microenvironment  express  immune-stimulating  cytokines  attracting  immune  cells  into  the  tumor.  Furthermore,  it  is
anticipated  that  the  anti-angiogenic  effect  of  VB-111  will  trigger  tumor  starvation,  destruction  of  tumor  cells  and  subsequent  release  of  cell  debris  and
tumor  neo-antigens  that  are  ingested  by  antigen  presenting  cells,  further  stimulating  the  anti-tumor  immune  response.  VB-111  specific  expression  in
endothelial  angiogenic  cells  focuses  the  immune  reaction  on  tumor  milieu  and  prevents  systemic  immune-mediated  damage.  In  2004,  we  published
preclinical data, which suggested that there is an immune inflammatory response to the presence of the viral vector and the Fas-TNFR1 chimera. Support
for  a  potential  role  of  the  immune  system  as  part  of  VB-111’s  mechanism  of  action  came  from  an  observation  that  patients  who  developed  fever  as  a
response to VB-111 administration, at least once along the treatment course, had a survival benefit over those who did not experience post-dosing fever.
Moreover, an immunotherapeutic effect was also observed in biopsies taken from ovarian cancer patients. Immunohistochemistry staining showed regions
of apoptotic cancer cells and infiltration of cytotoxic CD8 T-cells following treatment with VB-111.

VB-111’s mechanism of action is illustrated below:

Unlike  anti-VEGF  agents  (such  as  Avastin®)  or  tyrosine-kinase  inhibitors  (TKIs),  VB-111  does  not  aim  to  block  a  specific  pro-angiogenic  pathway;
instead, it uses an angiogenesis-specific sensor (our PPE-1-3x proprietary promoter) to specifically induce cell death in angiogenic endothelial cells in the
tumor milieu. This mechanism may retain activity regardless of baseline tumor mutations or the identity of the pro-angiogenic factors secreted by the tumor
and shows activity even after failure of prior treatment with other anti-angiogenics. Moreover, VB-111 induces specific anti-tumor immune response, which
is  accompanied  by  recruitment  of  CD8  T-cells  and  apoptosis  of  tumor  cells.  We  believe  that  this  mode  of  action  makes  VB-111  less  susceptible  to
resistance and, therefore, potentially applicable for a broader patient population than current therapies.

We have conducted preclinical studies in animal models of lung cancer, colon cancer, thyroid cancer, rGBM and melanoma. Based on those studies, and
clinical results to date, we believe that VB-111 has anti-tumoral activity that may hold clinical promise and may be suitable for treatment of some solid
tumors. We currently advance VB-111 in a randomized-controlled Phase 3 study in platinum-resistant ovarian cancer.

VB-111 Clinical Programs- Overview

We initially studied VB-111 in a Phase 1 “all comers” trial involving patients with multiple types of advanced metastatic cancer types, including thyroid
cancer, neuroendocrine cancer, renal cell carcinoma and lung cancer. In that trial, VB-111 was well-tolerated and showed a dose-dependent extension in
median overall survival across a range of tumor types. Based on these results, we decided to proceed with the development of VB-111 for rGBM, as well as
to investigate VB-111 as a monotherapy for the treatment of thyroid cancer and, in combination with chemotherapy, for ovarian cancer. We have an open
IND for VB-111 with the Office of Tissues and Advanced Therapies within FDA’s Center for Biologics Evaluation and Research.

VB-111 Clinical Program in Ovarian Cancer

Ovarian  cancer  is  the  leading  cause  of  gynecologic  cancer  death  in  the  United  States  affecting  approximately  22,000  women  annually.  In  patients  with
platinum-resistant disease, addition of the anti-angiogenic agent bevacizumab to chemotherapy has resulted in significantly improved PFS and response
rate. However, the addition of bevacizumab did not result in a significant improvement of OS. Given the limited response to additional therapies, there is an
unmet  need  to  make  significant  improvements  in  the  outcomes  of  patients  with  recurrent  platinum-resistant  ovarian  cancer  following  first  line  therapy.
Therefore, we conducted a Phase 1/2 clinical trial in ovarian cancer using VB-111 in combination with paclitaxel, a common chemotherapeutic agent.

This trial was designed as a Phase 1/2 dose escalation study. The primary objectives were to evaluate the safety and tolerability and identify dose limiting
toxicity in combination of VB-111 and weekly paclitaxel; and explore the efficacy in an expanded cohort of the optimally tolerated dose of combination
VB-111 and weekly paclitaxel, based on RECIST response, CA-125 response, progression free survival (PFS) and overall survival (OS) in patients with
recurrent platinum-resistant ovarian cancer.

Twenty one patients with recurrent platinum-resistant Müllerian/ovarian cancer were enrolled at Massachusetts General Hospital and Dana-Farber Cancer
Institute, and received up to 7 doses of treatment. Patients were treated in two consecutive cohorts: Low Dose Treatment (n=4, 3x1012 VPs + 40mg/80 mg
paclitaxel) or a Therapeutic Dose (n=17, 1x1013 VPs + 80 mg paclitaxel). Papillary serous carcinoma was the most common histology (n=9, 42.9%); with
other histologic subtypes including clear cell, adenocarcinoma, carcinosarcoma, and other (transitional/serous, mixed serous and clear-cell, and high grade
serous with malignant mixed mullerian tumor components). The most common cancer stage at diagnosis was IIIC (n=12, 64.7%). Patients had been treated
with  a  mean  number  of  2.6  prior  therapies.  Fifty-two  percent  received  prior  anti-angiogenic  treatment,  including  Avastin,  and  48%  were  considered
platinum refractory having a platinum free interval of less than 3 months. Median age at enrollment was 65 (41-79).

Trial results showed a significant increase in overall survival at the therapeutic dose of VB-111 vs. the low dose level (498 vs. 172 days, p=0.03). Among
the evaluable patients treated with the therapeutic dose, 58% (7/12) had a GCIG CA-125 response confirmed over four weeks. Mean duration of response
was 10 months (range 1.5-24.9). Objective CA-125 response was associated with improved survival. Median OS was 808 vs. 351 days in patients with CA-
125 decrease of 50% compared to those without 50% decrease in CA-125 (P=0.067). Post treatment fever occurred in 29% and was also associated with a
signal for improved survival: median OS was 808 days in patients with fever compared to 479 days in patients without fever (p=0.27).

The 58% GCIG CA-125 response represents an approximate doubling in response rate, compared to historical data with ovarian cancer patients treated
with a combination of Avastin ® and chemotherapy in the AURELIA trial which reported CA-125 response in 11.6% of patients treated with chemotherapy
and 31.8% CA-125 response in ovarian cancer patients treated with a combination of chemotherapy and Avastin ®.

An immunotherapeutic effect was also observed in biopsies taken from patients. H&E and immunohistochemistry staining showed regions of apoptotic
cancer cells and infiltration of cytotoxic CD8 T-cells following treatment with VB-111. VB-111 was found to be safe and well tolerated. The most common
VB-111  related  AEs  were  transient  mild-moderate  fever/flu  like  symptoms,  characteristic  of  infection  with  a  viral  vector.  These  events  were  generally
grade 1-2 and responded to antipyretic treatment. No dose limiting toxicities were reported at any dose level.

In December 2016 we had an end-of-Phase 2 meeting with the FDA to discuss the clinical path of VB-111 in ovarian cancer. We reached agreement with
the FDA on our clinical plan to proceed to a Phase 3 registration enabling study of VB-111 in platinum-resistant patients. We intend to advance VB-111 for
this  patient  population,  for  which  most  current  therapies  fail  to  prolong  patient  survival,  and  in  December  2017  announced  the  enrollment  of  the  first
patient in the OVAL registration enabling Phase 3 study of VB-111 in platinum-resistant ovarian cancer. The OVAL study is conducted in collaboration
with the Gynecologic Oncology Group (GOG) Foundation, Inc., a leading organization for research excellence in the field of gynecologic malignancies.

The randomized, controlled, double-blind, Phase 3 OVAL international study in recurrent platinum-resistant ovarian cancer has been designed to enroll up
to 400 adult patients at approximately 75 clinical sites in the United States, Europe, Israel and Japan. Patients are randomized 1:1 to VB-111 (1x1013 VPs
once  every  8  weeks)  in  combination  with  chemotherapy  (80mg/m2  paclitaxel  once  weekly),  or  to  placebo  with  chemotherapy.  The  primary  endpoint  is
overall survival. Additional endpoints include objective response rate (ORR), PFS, CA-125, RECIST 1.1 response and patient reported outcome measures.

In  March  2020,  we  announced  results  of  a  pre-specified  interim  analysis  in  the  OVAL  study,  which  reviewed  unblinded  data  and  assessed  CA-125
response, measured according to the GCIG criteria, in the first 60 enrolled subjects evaluable for CA-125 analysis. Based on the overall response rate in the
first  60  patients  across  both  arms  of  53%,  and  assuming  balanced  randomization  and  an  absolute  advantage  of  10%  or  higher  to  the  VB-111  arm,  the
response rate in the treatment arm (VB-111 in addition to weekly paclitaxel) was calculated to be 58% or higher. In patients who had post-dosing fever,
which is a marker for VB-111 treatment, the response rate was 69%. The futility rule determined for this analysis was that the response rate of VB-111
must be greater than the response rate of placebo by at least 10% in order to continue the study. This rule was successfully met. Based on the results of the
interim analysis, the DSMC recommended continuing the trial as planned. Results of the interim analysis were published in an international peer reviewed
journal (Arend et al., Gynecol Oncol. 2021).

In August 2020, we announced that the DSMC completed its pre-planned review of unblinded Overall Survival (OS), response rate and safety data of the
first 100 randomized patients with a follow-up of at least 3 months. The committee recommended that the study continue as planned. A subsequent DSMC
pre-planned review of the OVAL study was announced in February 2021, with a dataset of 200 treated patients. The committee found no safety issues with
the trial and recommended its continuation as planned.

The  OVAL  study  is  progressing  according  to  plan.  Periodic  DSMC  reviews  in  the  OVAL  study  are  planned  twice  a  year.  The  next  DSMC  review  is
expected in the third quarter of 2021. We expect to complete patient enrollment in the OVAL study at the end of 2021 or in early 2022.

VB-111 Clinical Program in GBM

Glioblastoma  is  a  brain  cancer  that  affects  approximately  12,000  to  13,000  newly  diagnosed  people  each  year  in  the  United  States.  It  is  a  devastating,
rapidly progressing tumor, with a median time from diagnosis to the patient’s death of 12 to 15 months. In recurrent glioblastoma, treatment consists of
both symptomatic and palliative therapies. However, with currently available therapies, glioblastoma typically remains fatal within a very short period of
time.

We conducted an open-label Phase 2 trial in rGBM, which was originally initiated as an adaptive Phase 1/2 trial. The trial was intended to evaluate the
safety and efficacy of VB-111, both by itself and in combination with bevacizumab, an anti-angiogenesis agent approved by the FDA for use in rGBM. In
this trial, patients were initially dosed with VB-111 alone. After disease progression on VB-111 alone, they receive either bevacizumab alone as standard of
care, or, in a second cohort, a combination of VB-111 and bevacizumab. Disease progression was defined as a worsening of the patient’s cancer with an
increase of at least 25% in the overall mass of measurable tumors, the appearance of new tumors, the worsening of non-measurable tumors since beginning
of treatment, a need for an increased dose of corticosteroids or clinical deterioration.

Our  Phase  2  trial  results  include  46  patients  with  rGBM  treated  with  VB-111;  upon  disease  progression,  23  patients  were  treated  with  VB-111  in
combination with Avastin ®, and 22 received Avastin ® alone. One patient, who received VB-111 monotherapy and achieved a complete response, is stable
for more than 6 years as of January 2020, and was included in the continuous exposure cohort. The median number of bi-monthly VB-111 doses was four
for  the  cohort,  which  was  treated  with  VB-111  through  progression,  versus  one  in  the  limited  exposure  cohort  (average  of  4.7  vs.  2.2,  respectively).
Continuous  exposure  to  VB-111  demonstrated  significant  improvement  in  overall  survival,  with  median  overall  survival  of  59.1  weeks  (414  days),
compared to 31.9 weeks (223 days) in patients on limited VB-111 exposure (p=0.043), meeting the primary endpoint of the trial. Two complete responses
and five partial responses were seen in the VB-111 continuous exposure cohort (n=24), compared to only two partial responses in VB-111 limited exposure
cohort (n=22). VB-111 was found to be well tolerated.

The trial data also showed that VB-111 may induce an immuno-therapeutic effect. Of the 46 patients who received VB-111, 25 patients experienced a fever
post-dosing of VB-111 at least once, while 21 patients did not. Patients with fevers demonstrated increased overall survival of 16 months, compared to
patients without fevers, who had a median overall survival of 8.5 months (p=0.03). Additional biomarkers analyses presented at the SNO conference in
November 2017 have demonstrated that in addition to fever, VB-111 is also associated with immune-mediated responses, including secretion of immune-
stimulatory cytokines that correlate with OS, further supporting a role of the immune system as part of VB-111’s dual mechanism of action.

In June 2016 at the ASCO conference, we presented clinical data that demonstrate a significant overall survival benefit in rGBM patients receiving VB-111
compared  with  historical  Avastin  ®  meta-analysis  data.  In  the  Phase  2  VB-111  trial,  the  median  overall  survival  of  patients  who  received  continuous
exposure  of  VB-111  in  combination  with  Avastin  was  59.1  weeks.  This  is  compared  to  32.1  weeks  in  the  pooled  data  from  the  8  studies  in  the  meta-
analysis (p=0.0295; Hazard Ratio 0.62, 95% CI: 0.40-0.96). Median survival ranged from 26.0 weeks to 45.7 weeks in the meta-analysis. Overall survival
at 12 months for patients on continuous exposure of VB-111 was 57%, compared with 24% overall survival (range 16%-38%) for the pooled Avastin ®
treated rGBM data (p=0.03).

In 62 patients with rGBM, the most frequent toxicity was self-limited fever, starting several hours post therapy and usually resolving within 24 hours and
controlled  with  anti-pyretics.  There  were  22  adverse  events  classified  as  grade  3  or  higher,  of  which  7  were  considered  possibly  related  to  VB-111
including asthenia, pyrexia, brain edema, depressed consciousness, pulmonary embolism, or PE (in a patient with PE prior to enrollment in the trial) and
hypertension.  Safety  results  were  reviewed  five  times  by  the  trial  Data  and  Safety  Monitoring  Board,  as  well  as  by  the  FDA,  without  safety  concerns.
Based  on  interim  Phase  2  data  of  VB-111  in  rGBM,  the  FDA  has  allowed  VBL  to  launch  a  Phase  3  study  of  VB-111  in  rGBM  patients  prior  to  the
completion of the Phase 2 trial.

Our  Phase  3  GLOBE  study  in  rGBM  compared  upfront  concomitant  administration  of  VB-111,  without  priming,  and  bevacizumab  to  bevacizumab
monotherapy. The study, which enrolled a total of 256 patients in the US, Canada and Israel was conducted under a special protocol assessment, or SPA,
agreement with the U.S. Food and Drug Administration, or FDA, with full endorsement by the Canadian Brain Tumor Consortium (CBTC).

Three safety reviews were conducted during the GLOBE trial, by the independent DSMC. In December 2016, we announced that the DSMC reviewed the
GLOBE safety data collected through a cutoff date in September 2016, and did not find any adverse events that would be cause for concern. As a result, the
DSMC  recommended  that  the  study  continue  as  planned.  In  April  2017,  we  announced  that  the  committee  reviewed  the  GLOBE  safety  data  collected
through a cutoff date in March 2017 and unanimously recommended that the study continue as planned. The third and final DSMC review took place in
September 2017. The committee reviewed the GLOBE safety data, including mortality data, collected through a cutoff date in August 2017, and stated that
they  did  not  identify  any  safety  concerns.  The  DSMC  confirmed  that  no  additional  follow  up  will  be  necessary.  Accordingly,  the  DSMC  unanimously
recommended that the study continue as planned, to completion.

On March 8, 2018, we announced top-line data from the GLOBE study. In this modified regimen, the treatment did not improve overall survival (OS) and
PFS outcomes in rGBM. No new safety concerns associated with VB-111 have been identified in the GLOBE study. Thorough analyses of the baseline risk
factors of the Phase 2 and the Phase 3 treatment groups did not reveal any differences. Therefore, patient selection or different patient populations could not
explain the difference between the results of the two studies.

Study results (Cloughesy et al. Neuro Oncol. 2019) attribute the contradictory outcomes between the Phase 2 and Phase 3 trials as being related to the lack
of VB-111 monotherapy priming in the GLOBE study, providing clinical, mechanistic and radiographic support for this hypothesis. Notably, GLOBE data
show improved outcomes associated with a post VB-111 fever reaction, similar to outcomes from previous VB-111 studies, providing support that fever is
a potential biomarker for better survival with VB-111, secondary to the drug’s immunologic mechanism of action.

Based on the understanding that study regimen may be a key factor for VB-111 activity in rGBM, we believe the outcome of the GLOBE study will not
necessarily have implications on the prospects for VB-111 in other regimens or tumor types. In March 2021, we announced that patient dosing has been
initiated  in  a  Phase  2  clinical  trial  investigating  VB-111  for  the  treatment  of  rGBM.  The  Phase  2  study,  sponsored  by  Dana-Farber  Cancer  Institute  in
collaboration with a group of top neuro-oncology US medical centers, will investigate neo-adjuvant and adjuvant treatment with VB-111 in rGBM patients
undergoing a second surgery.

VB-111 Program in Thyroid Cancer

We conducted an exploratory Phase 2 clinical trial to evaluate safety and efficacy of VB-111 in advanced thyroid cancer. According to the National Cancer
Institute (seer.cancer.gov), in 2017, there were an estimated 859,838 people living with thyroid cancer in the United States. The estimated number of new
US  cases  of  thyroid  cancer  in  2020  was  52,890.  Most  cases  can  be  treated  by  surgery  and  radioactive  iodine.  If  radioactive  iodine  is  ineffective,  other
treatments are prescribed, such tyrosine kinase inhibitors and systemic chemotherapy. However, if such treatments are unsuccessful, the therapeutic options
for  patients  are  currently  very  limited.  This  subset  of  patients  has  an  unmet  need  for  novel  therapeutic  options.  The  estimated  number  of  US  deaths  of
thyroid cancer in 2020 was 2,180.

Our  open-label  dose-escalating  study  enrolled  patients  with  advanced,  recently-progressive,  differentiated  thyroid  cancer  that  was  unresponsive  to
radioactive iodine, in two cohorts. Most patients had tumors that had not responded to multiple therapies prior to enrollment, including radiation and kinase
inhibitors. In the first cohort, thirteen patients received a single intravenous infusion of VB-111 at a sub-therapeutic dose of 3X1012 viral particles (VPs).

The second cohort included seventeen patients, who received VB-111 at a therapeutic dose of 10 13 VPs every two months until disease progression. One
patient proceeded from a single low dose to receive later multiple high doses at progression and was included in both groups (for PFS only).

On February 21, 2017, we announced full data from this trial. The primary endpoint of the trial, defined as 6-month progression-free-survival (PFS-6) of
25%, was met with a dose response. Forty-seven percent (47%; 8/17) of patients in the therapeutic-dose cohort reached PFS-6, versus 25% (4/12) in the
sub-therapeutic cohort, both groups meeting the primary endpoint. Reduction in tumor measurement after the first dose was seen in 44% (7/16) of patients
in the therapeutic-dose cohort, compared to 9% (1/11) in the sub-therapeutic-dose cohort. An overall survival benefit was seen with a tail of more than 40%
at  3.7  years  for  the  therapeutic-dose  cohort  (mOS  684  days).  This  is  similar  to  historical  data  for  pazopanib  (Votrient®),  a  tyrosine  kinase  inhibitor;
however, most patients in the VB-111 study had tumors that previously had progressed on pazopanib or other kinase inhibitors. VB-111 was observed to be
well-tolerated in this study, with no signs of clinically significant safety issues.

We  see  these  positive  data  as  additional  proof-of-concept  for  VB-111  in  another  advanced  solid  tumor,  particularly  important  for  investigating  the
therapeutic potential of VB-111 even as monotherapy. Our primary focus continues to be advancement of VB-111 towards commercialization, if approved,
in  ovarian  cancer.  Further  clinical  development  of  VB-111  for  thyroid  cancer  may  also  be  pursued,  potentially  with  a  strategic  partner,  or  via  an
investigator-sponsored study.

VB-111 Program in Colorectal Cancer

Based  on  support  from  preclinical  data,  which  we  presented  at  the  American  Society  of  Gene  &  Cell  Therapy  (ASGCT)  conference  in  May  2017,  and
histological  data  in  ovarian  cancer  showing  the  ability  of  VB-111  to  recruit  T-cells  into  ‘cold’  tumors,  we  believe  that  treatment  with  VB-111  may  be
further enhanced by addition of immune checkpoint inhibitors.

In  February  2020,  we  announced  the  launch  of  a  Phase  2  clinical  trial  of  VB-111  in  combination  with  nivolumab  (Opdivo®),  an  immune  checkpoint
inhibitor,  in  the  treatment  of  metastatic  colorectal  cancer  under  a  Cooperative  Research  and  Development Agreement  (CRADA)  between  VBL  and  the
National Cancer Institute (NCI). NCI serves as the IND sponsor for this study. The open label exploratory Phase 2 study will investigate if priming with
VB-111 can drive immune cells into the tumor and turn the colorectal tumors from being immunologically “cold” to “hot.” Enrollment in this clinical trial
started in September 2020. A preliminary readout in this study is expected in the first half of 2021.

Additional VTS Pipeline candidates

Our VTS platform technology enables systemic administration of gene therapy to either destroy or promote angiogenic blood vessels. Beyond VB-111, we
have  generated  additional  preclinical  product  candidates  which  utilize  the  same  vector  and  promoter  as  in  VB-111,  yet  comprise  alternative  functional
transgenes.  VB-511  is  an  anti-angiogenic  candidate,  while  VB-211  and  VB-411  are  pro-angiogenic  candidates  that  may  be  employed  for  ischemic
conditions like peripheral vascular disease.

Expanding our Pipeline - The VB-600 series of monoclonal antibodies targeting MOSPD2 for Inflammation and Oncology

We are conducting two parallel drug development programs that are exploring the potential of MOSPD2, a protein which we identified as a key regulator
of cell motility, as a therapeutic target for inflammatory diseases and cancer.

MOSPD2  is  a  membrane  protein  whose  function  was  unknown.  We  discovered  new  biological  findings,  which  seem  to  position  MOSPD2  as  a  critical
pathway controlling monocyte migration and as a key regulator of disease pathogenesis in different inflammatory autoimmune settings. Our data show that
inhibition of MOSPD2 by either knockdown, silencing or proprietary antibodies, results in a significant reduction in the ability of monocytes to migrate,
regardless of the inflammatory signals employed to attract them.

Since many of the receptors involved in regulation of immune cell migration are also utilized by cancer cells in the process of dissemination through the
body and formation of metastases, we asked whether MOSPD2 plays a role in this setting as well. We found that MOSPD2 was detected in the majority of
cancerous  organs,  including  colon,  esophagus,  liver  and  breast.  In  a  manuscript  published  in  the  International  Journal  of  Cancer  as  well  as  in  scientific
conferences, we showed that MOSPD2 is required for the migration and invasion of breast cancer cells in vitro, and that it promotes breast cancer cell
metastasis in vivo. Given the specificity of MOSPD2 expression and its highly elevated expression in tumors, we believe MOSPD2 can serve as a novel
mechanism for targeting of tumor cells.

Classical mAbs for Inflammatory Indications

Our  data  show  that  MOSPD2  which  is  predominantly  expressed  on  the  surface  of  human  monocytes,  is  essential  for  their  migration.  By  inhibiting  this
protein, we seek to block this migration of monocytes to sites of inflammation, and accordingly to reduce inflammation and tissue damage.

At the ECTRIMS 2018 meeting, we presented the critical role of MOSPD2 in the development of multiple sclerosis (MS) and its potential as a novel target
for treatment of inflammation in the Central Nervous System (CNS) and other organs. One of the key cell types that causes inflammation in MS is the
monocyte. In MS, monocytes that circulate in the peripheral blood infiltrate into the CNS and play a key role in the inflammatory process, particularly
through damaging the myelin coating which protects the nerve fibers, therefore leading to acute neurological symptoms. Using MOSPD2 knockout mice,
our data show that MOSPD2 was critical for the development of the disease in the experimental autoimmune encephalomyelitis (EAE) model for MS, as
knockout mice essentially do not develop the disease. Furthermore, we developed proprietary monoclonal antibodies against MOSPD2 that successfully
prevented development of EAE, and also showed activity in treatment of the animals after the neurological symptoms had already appeared.

Table of Contents

In September 2020, at the MS Virtual 2020 Meeting, we presented human proof-of-concept data that showed that our anti-MOSPD2 mAbs significantly
inhibited migration of monocytes isolated from all MS patients included in the study (n=33) by up to 97% (p<0.001), regardless of disease severity, gender
or  active  treatment.  The  activity  was  seen  not  only  in  the  monocytes  from  relapsing-remitting  patients,  but  also  those  from  primary  progressive  and
secondary  progressive  patients  with  high  Expanded  Disability  Status  Scale  (EDSS)  scores  of  5.5-6.5.  These  clinical  data  are  backed  up  by  strong
preclinical studies (Yacov et al., Clin Exp Immunol. 2020). We believe that our antibodies offer a novel mechanism for potential treatment of MS, through
blocking the accumulation of monocytes/macrophages in the central nervous system, which is differentiated from the existing available treatments, which
mostly target T and B cells.

In May 2020, we presented data at the Digestive Disease Week® (DDW) 2020 virtual meeting, demonstrating that treatment with anti-MOSPD2 antibody
decreased inflammation and fibrosis in a NASH model and reduced the disease activity in a colitis model. Knockout of MOSPD2 also lead to reduction in
liver fibrosis in a high-fat-high-carbohydrate model for NASH.

In  June  2020,  we  presented  data  at  the  European  League  Against  Rheumatism  (EULAR)  2020  Congress,  demonstrating  the  potential  of  anti-MOSPD2
mAbs for treatment of RA with differentiation from anti-TNF treatment. Data presented at Keystone symposia in February 2019 showed that mice in which
the MOSPD2 gene was knocked out had minimal or no disease in the collagen antibody-induced arthritis model for RA.

We  believe  that  antibodies  targeting  MOSPD2  have  potential  for  treatment  of  various  inflammatory  indications,  and  are  advancing  our  lead  preclinical
candidate VB-601 through IND-enabling studies. In September 2020, we announced the successful completion of a Type B pre-IND meeting with the FDA
regarding our development plan for VB-601. Toxicology studies for VB-601 are currently underway. Submission of an IND for the clinical development of
VB-601 is expected to occur in the first half of 2022.

Anti-MOSPD2 mAbs for Oncology Indications

We found that MOSPD2 was detected in the majority of cancerous organs, including colon, esophagus, liver and breast, where MOSPD2 seems to play a
key role in cancer cell metastasis (Salem et al., Int J. Cancer 2019). Our preliminary data indicate that knock-out of MOSPD2 in tumor cells may reduce
metastasis by 95% in some preclinical settings.

Based  on  these  findings,  our  approach  is  to  utilize  MOSPD2  as  a  target  for  attacking  tumor  cells.  We  presented  preclinical  proof-of-concept  for  this
approach in April 2018 at the AACR conference using a BiTE antibody, and in June 2020 using bi-specific full-IgG antibody candidates.

In  October  2020,  we  announced  that  the  European  Patent  Office  (EPO)  granted  Patents  #3328408  and  #3328401,  which  cover  VBL’s  proprietary
investigational anti-MOSPD2 monoclonal antibodies to treat inflammatory conditions and oncology conditions, respectively. The patents are expected to
provide protection for VBL’s MOSPD2 antibodies for inflammation and cancer, until at least July 2036.

Our Lecinoxoid Platform Technology

Our proprietary Lecinoxoid platform technology comprises a family of orally administered small molecules designed to modulate the body’s inflammatory
response.  Lecinoxoids  are  compounds  that  are  structurally  and  functionally  similar  to  naturally  occurring  molecules,  known  as  oxidized  phospholipids,
which possess immune modulating anti-inflammatory properties, modified to enhance stability and activity. We believe that Lecinoxoids hold significant
promise in their ability to treat a range of chronic immune-based inflammatory diseases.

45

 
 
 
 
 
 
 
 
 
 
 
Table of Contents

The  inflammatory  response  is  a  complex  physiologic  process  balancing  both  pro-  and  anti-  inflammatory  components  that  interact  intimately  with  the
body’s immune system. Oxidized phospholipids are instrumental in the interplay of these components that maintain equilibrium. When the inflammatory
response  is  not  adequately  balanced,  excess  inflammation  results  and  may  cause  both  acute  and  chronic  disease  states.  We  believe  that  by  identifying
naturally  occurring  anti-inflammatory  compounds  and  modifying  them  to  enhance  stability  and  activity  we  may  achieve  more  physiologically  balanced
responses than other available anti-inflammatory therapies.

VB-201

Our lead Lecinoxoid-based product candidate, VB-201, was designed as an oral agent for the control of chronic inflammatory disorders. VB-201 is a Phase
2-stage immune-modulator that demonstrated activity in reducing vascular inflammation in a Phase 2 sub-study in psoriatic patients with cardiovascular
risk. It was also clinically studied for psoriasis and ulcerative colitis, however, our data did not support further development for these indications. VB-201
has demonstrated tolerability in over 600 patients across eight clinical trials. We believe that VB-201 has potential in other disorders in which TLR-2 and
TLR-4 or monocytes play a role, such as atherosclerosis, NASH/Liver fibrosis and renal fibrosis.

As monocytes/macrophages play a key role in the cytokine storm seen with COVID-19, targeting their accumulation in the lungs represents an encouraging
strategy for curbing hyper-inflammation and tissue damage. In January 2021, we announced the dosing of the first patient in a randomized controlled Phase
2 study of VB-201 for the treatment of COVID-19. The study will assess the ability of VB-201 to prevent clinical deterioration and reduce morbidity and
mortality in patients with severe COVID-19. This exploratory open-label study is designed to enroll 30 patients, randomized in equal ratio to VB-201 plus
standard  of  care  versus  standard  of  care.  The  study  is  being  conducted  in  Israel  and  is  currently  recruiting  patients.  For  additional  information  see
ClinicalTrials.gov Identifier: NCT04733833.

In  March  2019,  we  executed  an  exclusive  option  license  agreement  with  an  animal  health  company  for  the  development  of  our  proprietary  anti-
inflammatory molecule, VB-201, for veterinary use. We retain VB-201 rights for treatment of humans worldwide. Under the terms of the agreement, we
have granted an exclusive option license to explore the potential of VB-201 for animal health indications. In consideration, we received an undisclosed up-
front payment, and are entitled to receive additional development milestone payments. In April 2020, another milestone event under this agreement was
reached,  following  which  we  received  an  undisclosed  payment.  If  the  option  to  license  would  be  exercised,  we  will  receive  additional  milestones  and
royalties on net sales.

Beyond VB-201, we have developed second and third generations of Lecinoxoid product candidates. Our results highlight the potential of some of these
molecules, such as VB-703, a third generation candidate whose IP life-cycle can extend to the mid-2030s.

Manufacturing

We  generally  perform  process  development  for  our  drug  substance  candidates  and  manufacture  quantities  of  our  drug  candidates  necessary  to  conduct
preclinical studies and clinical trials of our drug candidates. We rely on third-party manufacturers to produce bulk drug substance required for our clinical
trials and expect to continue to rely on third parties to manufacture clinical trial drug supplies for the foreseeable future. We also contract with additional
third parties for the formulating, labeling, packaging, storage and distribution of the final drug products.

VB-111

Until  late  2017,  we  manufactured  the  active  pharmaceutical  ingredient  and  the  formulated  drug  product  of  VB-111  for  the  clinical  development  at  our
small-scale cGMP-compliant production facility in Or-Yehuda, Israel and pursuant to an arrangement with a third party in the United States.

In October 2017, we announced the opening of our new gene therapy manufacturing plant in Modi’in, Israel. This plant will be the commercial facility for
production of the Company’s lead product candidate, VB-111, if approved. The site design enables modular expansion of the manufacturing capacity, to
supply growing demand following commercialization. The Modi’in facility shall also enable us to comply with the restrictions of the Research Law and our
undertaking to the OCS that an essential portion of our VB-111 production, and in any event not less than the majority of VB-111 production, will remain
in Israel. In July 2019, our facility was certified by a European Union (EU) Qualified Person (QP) as being in compliance with EU Good Manufacturing
Practices (GMP). In November 2019 our facility was awarded by the Israeli Ministry of Health the Certificate of GMP Compliance of a Manufacturer.

Employees

As of March 1, 2021, we employed 38 employees, including 30 in research and development, and 8 in general and administrative positions, and of which
12 employees have either MDs or PhDs. All of our employees are located in Israel. We believe our employee relations are good.

Israeli  labor  laws  govern  the  length  of  the  workday,  minimum  wages  for  employees,  procedures  for  hiring  and  dismissing  employees,  determination  of
severance pay, annual leave, sick days, advance notice of termination of employment, equal opportunity and anti- discrimination laws and other conditions
of employment. Subject to specified exceptions, Israeli law generally requires severance pay upon the retirement, death or dismissal of an employee, and
requires  us  and  our  employees  to  make  payments  to  the  National  Insurance  Institute,  which  is  similar  to  the  U.S.  Social  Security  Administration.  Our
employees have defined benefit pension plans that comply with the applicable Israeli legal requirements.

None of our employees currently work under any collective bargaining agreements.

Report have been prepared in accordance with U.S. GAAP.

Overview

We are a clinical-stage biopharmaceutical company focused on the discovery, development and commercialization of first-in-class treatments for areas of
unmet  need  in  cancer  and  immune/inflammatory  indications.  We  have  developed  three  platform  technologies:  a  gene-therapy  based  technology  for
targeting newly formed blood vessels with focus on cancer, an antibody-based technology targeting MOSPD2 for immuno-oncology and anti-inflammatory
applications, and the Lecinoxoids, a family of small-molecules for chronic immune-related indications.

Our main program in oncology is based on our proprietary Vascular Targeting System, or VTS, platform technology, which we believe will allow us to
develop  product  candidates  for  multiple  oncology  indications.  The  VTS  technology  utilizes  genetically  targeted  therapy  to  destroy  newly  formed,  or
angiogenic, blood vessels. By utilizing a viral vector as a delivery mechanism, the VTS platform can also lead to induction or enhancement of a localized
anti-tumor immune response, thereby turning immunologically ‘cold’ tumors ‘hot’.

Our lead product candidate, VB-111, is a gene-based biologic that we are developing for solid tumor indications, and which we have advanced to programs
for ovarian cancer, recurrent glioblastoma, or rGBM, an aggressive form of brain cancer, and thyroid cancer. We have obtained fast track designation for
VB-111 in the United States for prolongation of survival in patients with glioblastoma that has recurred following treatment with standard chemotherapy
and  radiation.  We  have  also  received  orphan  drug  designation  for  GBM  in  both  the  United  States  and  Europe.  VB-111  has  also  received  an  orphan
designation for the treatment of ovarian cancer by the European Commission.

OVAL is our international Phase 3 randomized pivotal registration enabling clinical trial that compares a combination of VB-111 and paclitaxel to placebo
plus paclitaxel, in patients with platinum-resistant ovarian cancer. The study is planned to enroll 400 patients. In March 2020, we announced the outcome
of  the  planned  interim  analysis  in  the  OVAL  study.  The  OVAL  independent  Data  Safety  Monitoring  Committee  (DSMC)  reviewed  unblinded  data  and
assessed CA-125 response, measured according to the GCIG criteria, in the first 60 enrolled subjects evaluable for CA-125 analysis. The DSMC confirmed
that the study met the interim pre-specified efficacy criterion, of an absolute percentage advantage of 10% or higher CA-125 response rate for the VB-111
treatment  arm,  and  recommended  the  study  continue.  The  overall  response  rate  in  the  first  60  randomized  evaluable  patients  was  53%.  Assuming  a
balanced randomization, the response rate in the treatment arm (VB-111 in addition to weekly paclitaxel) was 58% or higher. In patients who had post-
dosing  fever,  which  is  a  marker  for  VB-111  treatment,  the  response  rate  was  69%.  Results  of  the  interim  analysis  were  published  in  a  peer-review
manuscript (Arend et al., Gynecol Oncol. 2021).

The  following  analysis  of  the  OVAL  study  was  conducted  in  August  2020.  The  DSMC  reviewed  unblinded  overall  survival  (OS)  data  of  the  first  100
enrolled subjects with a follow-up of at least 3 months. The committee also looked at response rate and safety information. The DSMC recommended that
the study continue as planned. The primary endpoint of the OVAL Phase 3 study is OS.

In February 2021, we announced the results of a subsequent DSMC pre-planned review of the OVAL study. The committee, which reviewed unblinded
data of 200 treated patients, found no safety issues with the trial and recommended its continuation as planned. The next DSMC review in the OVAL study
is expected in the third quarter of 2021. Our OVAL study is being conducted in collaboration with the GOG Foundation, Inc., a leading organization for
research excellence in the field of gynecologic malignancies.

Final results from our Phase 1/2 clinical trial of VB-111 for recurrent platinum-resistant ovarian cancer were reported in June 2019 and published online in
April 2020 (Arend et al., Gynecol Oncol. 2020). Data demonstrated a median OS of 498 days in the VB-111 therapeutic-dose arm, versus 172.5 days in the
low-dose arm (p=0.03). 58% of evaluable patients treated with the therapeutic dose of VB-111 had a GCIG CA-125 response. VB-111 activity signals were
seen despite unfavorable prognostic characteristics (48% platinum refractory disease and 52% previous treatment with anti-angiogenics). There was a trend
for favorable survival in patients who had CA-125 decrease >50% in the VB-111 therapeutic-dose arm (808 vs. 351 days; p=0.067) implicating CA-125 as
a potentially valuable biomarker for response to VB-111. Post treatment fever was also associated with a signal for improved survival (808 vs. 479 days;
p=0.27).

In a Phase 2 study for rGBM, patients who were primed with VB-111 monotherapy that was continued after progression with the addition of bevacizumab
(Avastin®)  showed  significant  survival  (414  vs  223  days;  HR  0.48;  p=0.043)  and  progression  free  survival  (PFS)  advantage  (90  vs  60  days;  HR  0.36;
p=0.032) compared to a cohort of patients that had limited exposure to VB-111 (Brenner et al., Neuro Oncol. 2019). Radiographic responders to VB-111
exhibited specific imaging characteristics related to its mechanism of action. Survival advantage was also seen in comparison to historic controls, with the
percentage of patients living more than one year doubling from 24% to 57%.

Our  Phase  3  GLOBE  study  in  rGBM  compared  upfront  concomitant  administration  of  VB-111,  without  priming,  and  bevacizumab  to  bevacizumab
monotherapy. The study, which enrolled a total of 256 patients in the US, Canada and Israel was conducted under a special protocol assessment, or SPA,
agreement  with  the  U.S.  Food  and  Drug  Administration,  or  FDA,  with  full  endorsement  by  the  Canadian  Brain  Tumor  Consortium  (CBTC).  In  this
modified regimen, the treatment did not improve overall survival (OS) and PFS outcomes in rGBM. Study results (Cloughesy et al. Neuro Oncol. 2019)
attribute the contradictory outcomes between the Phase 2 and Phase 3 trials as being related to the lack of VB-111 monotherapy priming in the GLOBE
study, providing clinical, mechanistic and radiographic support for this hypothesis. Notably, GLOBE data show improved outcomes associated with a post
VB-111 fever reaction, similar to outcomes from previous VB-111 studies, providing support that fever is a potential biomarker for better survival with
VB-111, secondary to the drug’s immunologic mechanism of action. No new safety concerns associated with VB-111 have been identified in the study. We
do not think that results of the GLOBE study will necessarily have implications on the prospects for VB-111 in other regimens or tumor types.

On March 1, 2021, we announced that patient dosing has been initiated in a Phase 2 clinical trial investigating VB-111 for the treatment of rGBM. The new
Phase 2 study, sponsored by Dana-Farber Cancer Institute in collaboration with a group of top neuro-oncology US medical centers, will investigate neo-
adjuvant and adjuvant treatment with VB-111 in rGBM patients undergoing a second surgery.

In  February  2020,  we  announced  the  launch  of  a  phase  2  clinical  trial  of  VB-111  in  combination  with  nivolumab  (Opdivo®),  an  immune  checkpoint
inhibitor, in the treatment of metastatic colorectal cancer. Under a Cooperative Research and Development Agreement (CRADA) between VBL and the
National Cancer Institute (NCI), NCI will serve as the IND sponsor for this study. IND application for the study has been approved by the FDA. This new
study will investigate if priming with VB-111 can drive immune cells into the tumor and turn the colorectal tumor from immunologically ‘cold’ to ‘hot’.
The addition of nivolumab to VB-111 may further boost the anti-tumor immune response.

VB-111 is also being studied in combination with nivolumab, an anti-PD1 immune checkpoint inhibitor, in the treatment of metastatic colorectal cancer.
The study is being sponsored by the U.S. National Cancer Institute under a Cooperative Research and Development Agreement, or CRADA. The open
label exploratory Phase 2 study will investigate if priming with VB-111 can drive immune cells into the tumor and turn the colorectal tumors from being
immunologically “cold” to “hot.” Enrollment in this clinical trial started in September 2020. A preliminary readout in this study is expected in the first half
of 2021.

In  February  2017,  we  reported  full  data  from  our  exploratory  Phase  2  study  of  VB-111  in  recurrent,  iodine-resistant  differentiated  thyroid  cancer.  The
primary endpoint of the trial, defined as 6-month progression-free-survival (PFS-6) of 25%, was met with a dose response. Forty-seven percent of patients
in the therapeutic-dose cohort reached PFS-6, versus 25% in the sub-therapeutic cohort, both groups meeting the primary endpoint. An overall survival
benefit was seen, with a tail of more than 40% at 3.7 years for the therapeutic-dose cohort, similar to historical data for pazopanib (Votrient ®), a tyrosine
kinase inhibitor; however, most patients in the VB-111 study had tumors that previously had progressed on pazopanib or other kinase inhibitors.

Over 300 patients were exposed to VB-111 in completed clinical trials and it has been observed to be well-tolerated. In December 2015, we have been
granted a US composition of matter patents that provides intellectual property protection for VB-111 in the US until October 2033 before any patent term

We are also conducting two parallel drug development programs that are exploring the potential of MOSPD2, a protein that we identified as a key regulator
of cell motility, as a therapeutic target for inflammatory diseases and cancer.

For inflammatory applications, we are developing classical antibodies that are designed to bind and block MOSPD2 on immune cells. Our data show that
MOSPD2, which is predominantly expressed on the surface of human monocytes, is essential for their migration. By inhibiting this protein, we seek to
block this migration of monocytes to sites of inflammation, and accordingly to reduce inflammation and tissue damage. We believe that antibodies targeting
MOSPD2 have potential for treatment of various inflammatory indications, and are advancing our lead preclinical candidate VB-601 through IND-enabling
studies. In September 2020, we announced the successful completion of a Type B pre-IND meeting with the FDA regarding our development plan for VB-
601. Toxicology studies for VB-601 are currently underway. Submission of an IND for the clinical development of VB-601 is expected to occur in the first
half of 2022.

For oncology applications, we are developing antibodies aimed to kill tumor cells, based on MOSPD2 as a target whose expression is induced in multiple
tumors. We found that MOSPD2 was detected in the majority of cancerous organs, including colon, esophagus, liver and breast, where MOSPD2 seems to
play a key role in cancer cell metastasis (Salem et al., Int J. Cancer 2019). Given the specificity of MOSPD2 expression and its highly elevated expression
in tumors, we believe MOSPD2 can serve as a novel target for immuno-oncology mediated therapy for cancer.

In  October  2020,  we  announced  that  the  European  Patent  Office  (EPO)  has  granted  Patents  #3328408  and  #3328401,  which  cover  VBL’s  proprietary
investigational anti-MOSPD2 monoclonal antibodies to treat inflammatory conditions and oncology conditions, respectively. The patents are expected to
provide protection for VBL’s MOSPD2 antibodies for inflammation and cancer, until at least July 2036.

We also have been conducting a program targeting anti-inflammatory diseases, based on the use of our Lecinoxoid platform technology. Lecinoxoids are a
novel  class  of  small  molecules  we  developed  that  are  structurally  and  functionally  similar  to  naturally  occurring  molecules  known  to  modulate
inflammation.  The  lead  product  candidate  from  this  program,  VB-201,  is  a  Phase  2-stage  molecule  that  demonstrated  efficacy  in  reducing  vascular
inflammation  in  a  Phase  2  sub-study  in  psoriatic  patients  with  cardiovascular  risk.  Due  to  business  limitations  associated  with  the  heavy  burden  of
developing medications for cardiovascular diseases, we chose to test it in psoriasis and ulcerative colitis; however, as we reported in February 2015, VB-
201 failed to meet the primary endpoint in Phase 2 clinical trials for psoriasis and for ulcerative colitis.

In January 2021, we announced the dosing of the first patient in a randomized controlled Phase 2 study of VB-201 for the treatment of COVID-19. The
study will assess the ability of VB-201 to prevent clinical deterioration and reduce morbidity and mortality in patients with severe COVID-19. Based on
recent preclinical studies, we also believe that VB-201 and some second generation molecules such as VB-703 may have potential applicability for NASH
and renal fibrosis.

In  October  2017,  we  announced  the  opening  of  our  new  gene  therapy  pharmaceutical  grade  manufacturing  plant  in  Modi’in,  Israel.  The  facility  was
established to support the commercial supply of VB-111 for the first indication, if approved. The Modi’in facility is the first commercial-scale gene therapy
manufacturing  facility  in  Israel  (20,000  sq.  ft.).  In  July  2019,  our  facility  was  certified  by  a  European  Union  (EU)  Qualified  Person  (QP)  as  being  in
compliance with EU Good Manufacturing Practices (GMP). In November 2019 our facility was awarded by the Israeli Ministry of Health the Certificate of
GMP Compliance of a Manufacturer.

In November 2017, we signed an exclusive license agreement with NanoCarrier Co., Ltd. (TSE Mothers:4571) for the development, commercialization,
and supply of VB-111 in Japan. VBL retains rights to VB-111 in the rest of the world. Under terms of the agreement, VBL has granted NanoCarrier an
exclusive license to develop and commercialize VB-111 in Japan for all indications. VBL will supply NanoCarrier with VB-111, and NanoCarrier will be
responsible for all regulatory and other clinical activities necessary for commercialization in Japan. Under the agreement, VBL is entitled to receive greater
than $100 million in development and commercial milestone payments, in addition to tiered royalties on net sales in the high-teens.

In  March  2019,  we  executed  an  exclusive  option  license  agreement  with  an  animal  health  company  for  the  development  of  our  proprietary  anti-
inflammatory molecule, VB-201, for veterinary use. We retain VB-201 rights for treatment of humans worldwide. Under the terms of the agreement, we
have granted an exclusive option license to explore the potential of VB-201 for animal health indications. In consideration, we received an undisclosed up-
front payment, and are entitled to receive additional development milestone payments. In April 2020, another milestone event under this agreement was
reached,  following  which  we  received  an  undisclosed  payment.  If  the  option  to  license  would  be  exercised,  we  will  receive  additional  milestones  and
royalties on net sales.

In January 2021, we announced that we entered into an Ordinary Share Purchase Agreement with Aspire Capital Fund, LLC. Under the Agreement, Aspire
has committed to purchase up to $20 million of our ordinary shares at our discretion from time to time during a 30-month period at prices based on the
market price at the time of each sale. We will retain full control as to the timing and amount of any sale of ordinary shares to Aspire, subject to certain
limitations specified in the Purchase Agreement. There are no warrants or other derivative securities associated with the transaction. We have the right to
terminate the Purchase Agreement at any time without any additional cost or penalty.

We commenced operations in 2000, and our operations to date have been limited to organizing and staffing our company, business planning, raising capital,
developing our VTS, MOSPD2 and Lecinoxoid platform technologies and developing our product candidates, including conducting preclinical studies for
all  three  technologies  and  clinical  trials  of  VB-111  and  VB-201.  To  date,  we  have  funded  our  operations  through  private  sales  of  preferred  shares,  a
convertible  loan,  public  offering,  revenues  from  licensing  agreements  and  grants  from  the  Israeli  Office  of  Chief  Scientist,  or  OCS,  which  has  later
transformed to the Israeli Innovation Authority, or IIA, under the Israel Encouragement of Research and Development in Industry, or the Research Law. We
have no products that have received regulatory approval and accordingly have never generated regular revenue streams from sales of our products. Since
our inception and through December 31, 2020, we had raised an aggregate of $275.8 million to fund our operations, of which $113.4 million was from
sales of our equity securities, $40.5 from our initial public offering, or IPO, $15 million from a November 3, 2015 underwritten offering, approximately
$24.0 million from a June 7, 2016 registered direct offering, $17.9 million from a November 16, 2017 underwritten offering, $15.5 million from a June 27,
2018 registered direct offering, $18.1 million from both a May 11, 2020 and May 13, 2020 registered direct offerings, $28.8 million from IIA grants and
$2.6 million from at-the-market equity facility.

Since inception, we have incurred significant losses. For the years ended December 31, 2020, 2019 and 2018, our loss was $24.2 million, $19.4 million,
and $20.5 million, respectively. We expect to continue to incur significant expenses and losses for at least the next several years. As of December 31, 2020,
we had an accumulated deficit of $232.2 million. Our losses may fluctuate significantly from quarter to quarter and year to year, depending on the timing of
our  clinical  trials,  the  receipt  of  payments  under  any  future  collaborations  we  may  enter  into,  and  our  expenditures  on  other  research  and  development
activities.

 
 
 
 
 
 
 
 
 
 
 
 
As  of  December  31,  2020,  we  had  cash,  cash  equivalents,  short-term  bank  deposits  and  restricted  bank  deposits  of  $30.8  million.  To  fund  further
operations, we may need to raise additional capital. We may seek to raise more capital to pursue additional activities, which may be through a combination
of private and public equity offerings, government grants, strategic collaborations and licensing arrangements. Additional financing may not be available
when we specifically need it or may not be available on terms that are favorable to us. As of March 1, 2021, we had 38 employees.

Financial Overview

Revenues and Cost of Revenues

Since  inception,  we  generated  cumulative  revenues  of  approximately  $15.9  million  revenue  from  exclusive  license  agreements  for  the  development,
commercialization,  and  supply  of  VB-111  in  Japan  for  all  indications  and  an  option  to  license  agreement  for  the  development  of  VB-201  for  animal
healthcare  worldwide.  The  generated  revenues  comprise  upfront  and  milestone  payments.  The  cost  of  revenues  associated  with  these  payments  was
approximately  $1.1  million.  We  do  not  expect  to  receive  any  other  revenue  from  any  product  candidates  that  we  develop  unless  and  until  we  obtain
regulatory  approval  and  commercialize  our  products,  meet  regulatory  milestones  in  relation  to  our  existing  collaborative  agreements  or  enter  into  new
collaborative  agreements  with  third  parties.  For  more  detail  on  our  revenue  recognition  treatment  under  US  GAAP,  refer  to  Note  1.m.  to  our  Financial
reports.

Research and Development Expenses

Research and development expenses consist of costs incurred for the development of our three platform technologies and our product candidates. Those
expenses include:

● employee-related expenses, including salaries and share-based compensation expenses for employees in research and development functions;

● expenses incurred in operating our laboratories and small-scale manufacturing facility;

● expenses incurred under agreements with CROs and investigative sites that conduct our clinical trials;

● expenses relating to outsourced and contracted services, such as external laboratories, consulting and advisory services;

● supply, development and manufacturing costs relating to clinical trial materials;

● maintenance of facilities, depreciation and other expenses, which include direct and allocated expenses for rent and insurance; and

● costs associated with preclinical and clinical activities.

Research and development activities are the primary focus of our business. Product candidates in later stages of clinical development generally have higher
development costs than those in earlier stages of clinical development, primarily due to the increased size and duration of later-stage clinical trials. Our
research  and  development  expenses  may  increase  in  absolute  dollars  in  future  periods  as  we  continue  to  invest  in  research  and  development  activities
related to the development of our platform technologies and product candidates. In particular, our research and development expenses may increase as we
develop VB-111 beyond ovarian cancer, and continue its clinical development in other oncology indications. In addition, our research and development
expenses may increase as we develop our VB-600 series of product candidates.

Research  expenses  are  recognized  as  incurred.  An  intangible  asset  arising  from  the  development  of  our  product  candidates  is  recognized  if  certain
capitalization conditions are met. As of December 31, 2020, we did not have any capitalized development costs.

We  have  received  grants  from  the  IIA  as  part  of  the  research  and  development  programs  for  our  VTS  and  Lecinoxoid  platform  technologies.  The
requirements and restrictions for such grants are found in the Research Law. These grants are subject to repayment through future royalty payments on any
products resulting from these research and development programs, including VB-111 and VB-201. Under the Research Law, royalties of 3% to 3.5% on the
revenues  derived  from  sales  of  products  or  services  developed  in  whole  or  in  part  using  these  IIA  grants  are  payable  to  the  Israeli  government.  The
maximum aggregate royalties paid generally cannot exceed 100% of the grants made to us, plus annual interest generally equal to the 12-month LIBOR
applicable to dollar deposits, as published on the first business day of each calendar year. The total gross amount of grants actually received by us from the
IIA, including accrued LIBOR interest as of December 31, 2020 and 2019, totaled $36.0 million and $33.4 million, respectively.

The  Research  Law  is  targeted  at  maintaining  the  intellectual  property  and  manufacturing  rights  relating  to  IIA-funded  projects  in  Israel.  Under  certain
circumstances,  where  the  above  is  not  followed,  the  royalty  rate  might  be  higher  and  accordingly  calculated  to  a  formula  based  on  the  ratio  of  the
participation by the State in the project to the total project costs incurred us.

Table of Contents

In addition to paying any royalty due, we must abide by other restrictions associated with receiving such grants under the Research Law that continue to
apply following repayment to the IIA. These restrictions may impair our ability to outsource manufacturing, engage in change of control transactions or
otherwise  transfer  our  know-how  outside  of  Israel,  and  may  require  us  to  obtain  the  approval  of  the  IIA  for  certain  actions  and  transactions  and  pay
additional royalties and other amounts to the IIA. In addition, any change of control and any change of ownership of our ordinary shares that would make a
non-Israeli citizen or resident an “interested party,” as defined in the Research Law, requires prior written notice to the IIA. If we fail to comply with the
Research Law, we may be subject to criminal charges.

Under  applicable  accounting  rules,  the  grants  income  from  the  IIA  have  been  accounted  for  as  an  off-set  against  the  related  research  and  development
expenses in our financial statements. As a result, our research and development expenses are shown on our financial statements net of the IIA grants.

General and Administrative Expenses

General  and  administrative  expenses  consist  principally  of  salaries  and  related  costs  for  personnel  in  executive  and  finance  functions  such  as  salaries,
benefits  and  share-based  compensation.  Other  general  and  administrative  expenses  include  facility  costs  not  otherwise  included  in  research  and
development expenses, communication expenses, and professional fees for legal services, patent counseling and portfolio maintenance, consulting, auditing
and accounting services.

Marketing Expenses

Marketing expenses consists principally of salaries and related cost for personnel in marketing and commercialization functions such as salaries, benefits
and share-based compensation, in addition to commercialization consulting services.

Financial Expenses (Income), Net

Financial income is comprised of interest income generated from interest earned on our cash, cash equivalents and short-term bank deposits and gains and
losses due to fluctuations in foreign currency exchange rates mainly in the appreciation and depreciation of the NIS exchange rate against the U.S. dollar.

Financial expenses primarily consist of gains and losses due to fluctuations in foreign currency exchange rates.

Taxes on Income

We have not generated taxable income since our inception, and had carry forward tax losses as of December 31, 2020 of $198.1 million. We anticipate that
we will be able to carry forward these tax losses indefinitely to future tax years. Accordingly, we do not expect to pay taxes in Israel until we have taxable
income after the full utilization of our carry forward tax losses.

The Company recognizes full valuation allowance since we do not expect taxable income.

Critical Accounting Policies and Significant Judgments and Estimates

This  management’s  discussion  and  analysis  of  our  financial  condition  and  results  of  operations  is  based  on  our  financial  statements,  which  have  been
prepared in accordance with US GAAP. The preparation of these financial statements requires us to make estimates and assumptions that affect the reported
amounts  of  assets  and  liabilities  and  the  disclosure  of  contingent  assets  and  liabilities  at  the  date  of  the  financial  statements,  as  well  as  the  reported
expenses incurred during the reporting periods. Estimates and judgments are continually evaluated and are based on historical experience and other factors,
including expectations of future events that are believed to be reasonable under the circumstances.

We make estimates and assumptions concerning the future. The resulting accounting estimates will, by definition, seldom equal the related actual results.
The estimates and assumptions that have a significant risk of causing a material adjustment to the carrying amounts of assets and liabilities within the next
financial year are discussed below.

Revenue recognition

With respect to the License Agreement, the Company used its judgement in the following main issues:

Identifying the performance obligations in the agreement and determining whether the license provided is distinct - based on the Company’s analysis, the
license  is  distinct  as  the  licensee  is  able  to  benefit  from  the  license  on  its  own  at  its  current  stage  (inter  alia,  due  to  sublicensing  rights,  rights  and
responsibility for development in the territory, etc.).

Allocation  of  the  transaction  price  -  the  Company  estimated  the  standalone  selling  prices  of  the  services  to  be  provided  based  on  expected  cost  plus  a
margin and used the residual approach to estimate the standalone selling price of the license as the Company has not yet established a price for the license,
and it has not previously been sold on a standalone basis.

Variable consideration consists of potential future milestone payments. The Company determined that all such variable consideration shall be allocated to
the license (the satisfied performance obligation).

Share-Based Compensation

With respect to grants to employees, the value of the labor services received from them in return is measured on the date of grant based on the fair value of
the equity instruments granted to the employees.

The value of the transactions, measured as aforesaid, is expensed over the period during which the right of the employees and non-employees to exercise or
receive  the  underlying  equity  instruments  vests;  commensurate  with  every  periodic  recognition  of  the  expense,  a  corresponding  increase  is  recorded  to
additional paid in capital, included under the Company’s equity (see also Note 9).

Clinical trial accruals

Clinical trial expenses are charged to research and development expense as incurred. The Company accrues for expenses resulting from obligations under
contracts  with  clinical  research  organizations  (CROs).  The  financial  terms  of  these  contracts  are  subject  to  negotiations,  which  vary  from  contract  to
contract  and  may  result  in  payment  flows  that  do  not  match  the  periods  over  which  materials  or  services  are  provided.  The  Company  reflects  the
appropriate trial expense in the financial statements by matching the appropriate expenses with the period in which services and efforts are expended. As of
December 31, 2020, the company had clinical accruals in the amount of approximately $1.8 million.

Lease

In determining the lease term, we consider all facts and circumstances that create an economic incentive to exercise an extension option, or not exercise a
termination option. Extension options are only included in the lease term if the lease is reasonably certain to be extended. At initial recognition of lease
liability, we used incremental borrowing rate, which is the rate that the lessee would have to pay to borrow the funds necessary to obtain an asset of similar
value in a similar economic environment with similar terms and conditions (see also Note 5).

Revenues for the year ended December 31, 2020 were $922 thousand, compared to $562 thousand for the year ended in 2019 and $585 thousand for the
year ended December 31, 2018, an increase of $360 thousand or 64% and a decrease of $23 thousand or 4%, respectively.

The  Cost  of  revenues  for  the  year  ended  December  31,  2020  were  $394  thousand,  compared  to  $222  thousand  for  the  year  ended  in  2019  and  $255
thousand  for  the  year  ended  December  31,  2018.  The  cost  of  revenues  is  attributed  to  the  labor  costs  and  other  expenses  related  to  the  performance
obligations that were delivered during the period.

Research and development expenses, net

Research and development expenses are shown net of IIA grants. Research and development expenses, net for the year ended December 31, 2020 were
$19.7 million, compared to $14.7 million for the year ended December 31, 2019 and $15.2 million for the year ended December 31, 2018, an increase of
$4.9 million or 34% and a decrease of $0.5 million, or 3%, respectively.

The  increase  in  research  and  development  expenses,  net,  in  2020  was  comprised  of  an  increase  of  MOSPD2  and  Ovarian  Phase  III  activity  for
approximately $4.0 million in addition to a decrease in IIA grants received of approximately $1.3 million, offset mainly by payroll related costs for share-
based compensation expense of approximately $0.3 million.

The decrease in research and development expenses, net, in 2019 was comprised of a decrease of approximately $0.8 million in share-based compensation
costs, a decrease in internal manufacturing and facility expenses at our own new manufacturing facility of approximately $1.3 million for materials and
maintenance, a decrease of $4.3 million in costs incurred for the Phase 3 pivotal trial of VB-111 in rGBM that was at its peak activity in 2017 and ended in
2018 and an increase in the amounts of IIA grants received of $0.7 million in 2019 for the VB-111 program, offset by an increase of about $5.2 million in
2019 in the expenses for the Ovarian Phase 3 trial and $1.3 million for further pipeline developments.

General and administrative expenses

General and administrative expenses for the year ended December 31, 2020 were $5.3 million, compared to $5.7 million for the year ended December 31,
2019 and $6.0 million for the year ended December 31, 2018, a decrease of $0.4 million or 6%, and a decrease of $0.3 million or 5%, respectively.

This decrease in 2020 is mainly attributed to share-based compensation expense and financial advisory costs. The decrease in 2019 is mainly attributed to
share-based compensation expense.

Marketing expenses

No marketing expenses for the year ended December 31, 2020 and December 31, 2019. Marketing expenses for the year ended December 31, 2018 were
$0.4 million.

Financial expense (income), net

Financial expense (income), net for the year ended December 31, 2020 was ($258) thousand, compared to ($686) thousand for the year ended December
31, 2019, and ($749) thousand for the year ended December 31, 2018, a decrease of $428 thousand or 62% in income, and a decrease in income of $63
thousand or 8%, respectively. The decrease in 2020 is mainly due lower interest rates received compared to 2019. The increase in 2019 is mainly due less
favorable exchange rates in comparison to its preceding year.

Liquidity and Capital Resources

Since our inception and through December 31, 2020, we have raised a total of $113.4 million from sales of our equity securities before the initial public
offering, $40.5 million gross in our initial public offering ($34.9 million net), $15.0 million from a November 3, 2015 underwritten offering ($13.6 million
net), $24.0 million from a June 7, 2016 registered direct offering ($21.9 million net), $17.9 million from a November 16, 2017 underwritten offering, $15.5
million from a June 27 registered direct offering, $18.1 million from both a May 11, 2020 and May 13, 2020 registered direct offerings, $28.8 million from
IIA grants and $2.6 million from at-the-market equity facility . Our primary uses of cash have been to fund working capital requirements and research and
development, and we expect these will continue to represent our primary uses of cash. We intend to use our cash resources, together with the proceeds from
the offerings described above, to advance clinical programs, working capital, and other general corporate purposes. We expect that our cash resources as of
December 31, 2020 together with the additional cash from the exercise of outstanding warrants, ATM sales and share purchases by Aspire Capital after
January 1, 2021, would provide sufficient funding for our operations into the fourth quarter of 2022.

On May 17, 2019, we entered into an Equity Distribution Agreement with Oppenheimer & Co. Inc., or Oppenheimer to offer and sell from time to time its
ordinary shares, NIS 0.01 par value, having an aggregate offering price of up to $15,000,000 through Oppenheimer acting as its agent and/or principal. For
the  year  ended  December  31,  2020,  we  sold  an  aggregate  of  812,470  ordinary  shares  under  our  at-the-market  equity  facility.  The  total  consideration
amounted to $1.0 million, net of issuance costs. Since January 1, 2021 through March 15, 2021, we have sold an aggregate of 1,285,366 ordinary shares
under our at-the-market equity facility. The total consideration amounted to $3.5 million net of issuance costs. In addition, subsequent to December 2020,
we  received  additional  cash  from  the  exercise  of  4,861,906  warrants  from  our  May  2020  registered  direct  offerings  for  approximately  $7.0  million  and
from  the  share  purchases  of  800,000  shares  from  our  January  14,  2021  ordinary  share  purchase  agreement  with  Aspire  Capital  Fund,  LLC.  for
approximately $1.8 million.

Funding Requirements

On December 31, 2020, we had cash, cash equivalents, short-term bank deposits and restricted bank deposit of $30.8 million and working capital of $24.5
million.  We  expect  that  our  cash  and  cash  equivalents  and  short-term  bank  deposits  together  with  the  additional  cash  from  the  exercise  of  outstanding
warrants, ATM  sales  and  share  purchases  by  Aspire  Capital  after  January  1,  2021,  would  provide  sufficient  funding  for  our  operations  into  the  fourth
quarter of 2022. We are unable to estimate the amounts of increased capital outlays and operating expenses associated with completing the development of
VB-111 and our other product candidates. Our future capital requirements will depend on many factors, including:

● the costs, timing and outcome of regulatory review of VB-111 and any other product candidates we may pursue;

● the costs of future development activities, including clinical trials, for VB-111 and any other product candidates we may pursue;

● the costs of preparing, filing and prosecuting patent applications, maintaining and enforcing our intellectual property rights and defending intellectual

property-related claims;

● the extent to which we acquire or in-license other products and technologies; and

● our ability to establish any future collaboration arrangements on favorable terms, if at all.

Until such time, if ever, as we can generate substantial product revenue, we expect to finance our cash needs through a combination of equity offerings,
debt financings, collaborations, strategic alliances and licensing arrangements. We do not have any committed external source of funds. To the extent that
we raise additional capital through the sale of equity or convertible debt securities, the ownership interest of our shareholders will be diluted, and the terms
of  these  securities  may  include  liquidation  or  other  preferences  that  adversely  affect  your  rights  as  a  holder  of  our  ordinary  shares.  Debt  financing,  if
available,  may  involve  agreements  that  include  covenants  limiting  or  restricting  our  ability  to  take  specific  actions,  such  as  incurring  additional  debt,
making capital expenditures or declaring dividends. If we raise additional funds through collaborations, strategic alliances or licensing arrangements with
third parties, we may have to relinquish valuable rights to our technologies, future revenue streams or research programs or grant licenses on terms that
may not be favorable to us. If we are unable to raise additional funds through equity or debt financings when needed, we may be required to delay, limit,
reduce  or  terminate  our  product  development  or  future  commercialization  efforts  or  grant  rights  to  develop  and  market  VB-111  and  any  other  product
candidates that we would otherwise prefer to develop and market ourselves.

We  have  obligations  to  make  future  payments  to  third  parties  that  become  due  and  payable  on  the  achievement  of  certain  development,  regulatory  and
commercial milestones, such as the start of a clinical trial, filing of an NDA, approval by the FDA or product launch, or royalties upon sale of products. We

Agreement  with  Tel  Hashomer.  On  February  3,  2013,  we  entered  into  an  agreement  with  Tel  Hashomer-Medical  Research,  Infrastructure  and
Services Ltd., or Tel Hashomer, a private company whose purpose is to promote the welfare of the Sheba Medical Center, or the Hospital, and Prof.
Dror  Harats,  our  chief  executive  officer.  The  agreement  with  Tel  Hashomer  resolved  claims  of  the  Hospital  regarding  the  ownership  of  certain
inventions and patent rights owned by us and developed in part by Prof. Harats and other inventors who were engaged by us and by the Hospital in
parallel. The agreement provided us with a waiver of rights by the Hospital and Tel Hashomer in connection with intellectual property developed
by these inventors  prior  to  the  date  of  the  agreement.  In  consideration  for  the  waiver,  we  undertook  to  pay  1%  of  any  net  sales  of  any  product
covered  by  the  intellectual  property  covered  under  the  agreement,  which  includes  all  of  our  current  product  candidates,  and  2%  of  any
consideration that we receive for granting a license or similar rights to this intellectual property. Such amounts will be recorded as part of our cost
of  revenues.  In  addition,  upon  the  occurrence  of  an  exit  event  such  as  a  merger,  sale  of  all  shares  or  assets  or  the  closing  of  an  initial  public
offering, we are required to pay to Tel Hashomer 1% of the proceeds received by us or our shareholders as the case may be. In November 2014,

agreement.  For  the  cash  payment  received  to  date  in  this  transaction,  we  paid  Tel  Hashomer  an  additional  $747  thousand  royalty and all other
payment obligations under this agreement will expire once we have paid an aggregate sum of NIS 100 million (approximately $29 million) to Tel
Hashomer by way of pay out, exit proceeds and licensing consideration. Amounts previously paid as royalties on any net sales will not be taken
into account when calculating this aggregate sum.

Agreement with Janssen Vaccines & Prevention B.V. On April 15, 2011, we entered into a Commercial License Agreement with Janssen Vaccines
& Prevention B.V., or Janssen, for incorporating the adenovirus 5 in VB- 111 and other drug candidates for cancer for consideration including the
following potential future payments:

■

an annual license fee of € 100,000 ($123,000), continuing until the termination of the agreement, which will occur upon (i) the later
of the expiration date of the last related patent or 10 years from the first commercial sale of VB-111 or (ii) the termination of the
agreement by us, which is permitted, upon three months’ written advance notice to Janssen;

a milestone payment of € 400,000 ($492,000) upon receipt of the first regulatory approval for the marketing of the first indication
for each product covered under the agreement; and

royalties of 0.5%-2.0% on net sales.

In October 2016, we entered into a long-term lease contract for approximately $2.2 million over 7 years commencing May 2017 for a new facility
in Modi’in, Israel with the option to extend for an additional two periods of three years each. The site houses the Company’s local biological drugs
manufacturing facility, headquarters, discovery research and clinical development. Through December 31, 2020, expenses in the total amount of
approximately $1.3 million were incurred.

There are no limits or caps on the amount of potential royalties. Pursuant to the agreement, the Company has the right to terminate the agreement by giving
Janssen Vaccines & Prevention B.V. three months’ written notice.

Participation by the IIA. We receive grants from the IIA, as part of the oncology and anti-inflammatory research and development programs. The
requirements  and  restrictions  for  such  grants  are  set  forth  in  the  Research  Law.  These  grants  are  subject  to  repayment  through  future  royalty
payments on sales of any products resulting from these research and development programs, including VB-111 and VB-201. Under the Research
Law, we are obligated to pay royalties of 3% to 3.5%. The maximum aggregate royalties paid generally cannot exceed 100% of the grants made to
us, plus annual interest generally equal to the 12-month LIBOR applicable to dollar deposits, as published on the first business day of each calendar
year. The total gross amount of grants actually received by us from the IIA as of December 31, 2020 totaled approximately $28.8 million, and the
balance  of  the  principal  and  interest  in  respect  of  our  commitments  for  future  payments  to  the  IIA  totaled  approximately  $36.0  million  license
agreement. To date, we have paid the IIA in relation to our licenses agreement royalties of approximately $0.5 million.

Off-Balance Sheet Arrangements

Since our inception, we have not engaged in any off-balance sheet arrangements, as defined in the rules and regulations of the SEC, such as relationships
with  unconsolidated  entities  or  financial  partnerships,  which  are  often  referred  to  as  structured  finance  or  special  purpose  entities,  established  for  the
purpose of facilitating financing transactions that are not required to be reflected on our statements of financial position.

Board of Directors

Under the Israeli Companies Law, 5759-1999, or the Companies Law, the management of our business is vested in our board of directors. Our board of
directors may exercise all powers and may take all actions that are not specifically granted to our shareholders or to management. Our executive officers
are responsible for our day-to-day management and have individual responsibilities established by our board of directors. Our chief executive officer is
appointed by, and serves at the discretion of, our board of directors, subject to the employment agreement that we have entered into with him. All other
executive officers are also appointed by our board of directors, and are subject to the terms of any applicable employment agreements that we may enter
into with them.

Under our amended and restated articles of association, our board of directors must consist of at least three and not more than nine directors, including the
external directors. Our board of directors currently consists of eight directors. Following the adoption by the Company of certain reliefs provided under the
Companies Law, the Company is exempt from the requirement to appoint external directors and the individuals formerly appointed as external directors
continue to serve as part of our board of directors until the end of their term and may be removed from office in the same manner as any other director. We
have only one class of directors.

The following of our directors were elected in accordance with the terms of our articles of association in effect prior to the initial public offering of our
shares on NASDAQ and are nominated for re-election by our shareholders at any consecutive annual general meeting:

●

●

●

●

Dr.  Shapiro  was  appointed  as  an  industry  expert  by  a  majority  of  the  other  directors,  a  majority  that  included  representatives  of  our  major
shareholders.

Prof. Harats was entitled to be a board member for so long as Prof. Harats is either (i) the chief executive officer of our company; or (ii) a holder of
3% or more of our issued and outstanding share capital;

Ms. Alon was originally appointed by persons affiliated with Pitango Venture Capital; Since 2017 Ms. Alon is not related to Pitango She was re-
elected by the General Meeting of shareholders as an independent director.

Prof. Ruth Arnon was appointed by a majority of the other directors, which included representatives of our major shareholders.

Upon the adoption of our amended and restated articles of association upon the closing of our initial public offering, the rights set forth in the previous
articles were terminated and no additional agreements exist with respect to the nomination of our board members.

In accordance with the exemption available to certain Israeli public companies, whose shares are traded on NASDAQ, we chose as of November 7, 2016
not to follow the requirements of Companies Law with regard to the appointment of “external directors” as defined in the Companies Law, and instead, to
follow  the  NASDAQ  rules  applicable  to  US  domestic  companies  with  respect  to  the  appointment  of  independent  directors.  As  long  as  we  follow  such
reliefs, any reference to the election of our external directors in our amended articles of association shall have no actual expression.

We comply with NASDAQ rules that a majority of our directors are independent. Our board of directors has determined that with the exception of Prof.
Harats, all of our directors are independent under such rules.

In accordance with the exemption available to foreign private issuers under NASDAQ rules, we do not intend to follow the requirements of NASDAQ
rules with regard to the process of nominating directors, and instead, will follow Israeli law and practice, in accordance with which our board of directors
(or a committee thereof) is authorized to recommend to our shareholders director nominees for election. See “Item 16G. Corporate Governance” for more
information.

Under the Companies Law and our amended and restated articles of association, nominees for directors may also be proposed by any shareholder holding at
least 1% of our outstanding voting power. However, any such shareholder may propose a nominee only if a written notice of such shareholder’s intent to
propose a nominee has been given to our company secretary (or, if we have no such company secretary, our chief executive officer). Any such notice must
include certain information, including, among other things, a description of all arrangements between the nominating shareholder and the proposed director
nominee(s) and any other person pursuant to which the nomination(s) are to be made by the nominating shareholder, the consent of the proposed director
nominee(s) to serve as our director(s) if elected and a declaration signed by the nominee(s) declaring that there is no limitation under the Companies Law
preventing their election, and that all of the information that is required under the Companies Law to be provided to us in connection with such election has
been provided.

Table of Contents

In addition, our amended and restated articles of association allow our board of directors to appoint directors to fill vacancies on our board of directors, for
a term of office equal to the remaining period of the term of office of the director(s) whose office(s) have been vacated.

Under the Companies Law, our board of directors must determine the minimum number of directors who are required to have accounting and financial
expertise (as defined in the Companies Law). In accordance with the exemption available to certain Israeli public companies, whose shares are traded on
NASDAQ, our board of directors elected not to follow the requirements of Companies Law with regard to the appointment of directors with accounting
and financial expertise as defined in the Companies Law, and instead, to follow the NASDAQ rules applicable to US domestic companies with respect to
the financial expertise of the directors. The exemption applies as long as the Company has no controlling shareholder, is in compliance with applicable US
law and regulations and complies with the NASDAQ rules applicable to US domestic companies with respect to the appointment of independent directors
and to the composition of the compensation and audit committees. Our board may further resolve at any time that we shall no longer follow the reliefs and
in such event, we shall be required to appoint directors with accounting and financial expertise as defined in the Companies Law. Our board of directors has
determined that the minimum number of directors who are required to have accounting and financial expertise is one.

External Directors

Under the Companies Law, a public company is required to have at least two directors who qualify as external directors. In accordance with the exemption
available to certain Israeli public companies, whose shares are traded on NASDAQ and which do not have a controlling shareholder (the “Exemption to
Foreign-listed  Israeli  Companies”),  our  board  of  directors  elected  not  to  follow  the  requirements  of  Companies  Law  with  regard  to  the  appointment  of
“external directors” as defined in the Companies Law, and instead, to follow the NASDAQ rules applicable to US domestic companies with respect to the
appointment of independent directors. The exemption applies as long as the Company has no controlling shareholder, is in compliance with applicable US
law and regulations and complies with the NASDAQ rules applicable to US domestic companies with respect to the appointment of independent directors
and to the composition of the compensation and audit committees. Our board may further resolve at any time that we shall no longer follow the reliefs or
determine that we are no longer in compliance with the requirements of such exemption, and in such event, we shall be required to appoint two directors as
external directors.

Role of Board in Risk Oversight Process

Risk  assessment  and  oversight  are  an  integral  part  of  our  governance  and  management  processes.  Our  board  of  directors  encourages  management  to
promote a culture that incorporates risk management into our corporate strategy and day-to-day business operations. Management discusses strategic and
operational  risks  at  regular  management  meetings,  and  conducts  specific  strategic  planning  and  review  sessions  during  the  year  that  include  a  focused
discussion  and  analysis  of  the  risks  facing  us.  Throughout  the  year,  senior  management  reviews  these  risks  with  the  board  of  directors  at  regular  board
meetings  as  part  of  management  presentations  that  focus  on  particular  business  functions,  operations  or  strategies,  and  presents  the  steps  taken  by
management to mitigate or eliminate such risks.

Leadership Structure of the Board

In  accordance  with  the  Companies  Law  and  our  amended  and  restated  articles  of  association,  our  board  of  directors  is  required  to  appoint  one  of  its
members to serve as chairman of the board of directors. Our board of directors has appointed Dr. Shapiro to serve as chairman of the board of directors.

Committees of the Board of Directors

We have an audit committee, a compensation committee and a nominating and corporate governance committee. We have adopted a charter for each of
these committees.

Audit Committee

Under the Companies Law, we are required to appoint an audit committee. The audit committee must be comprised of at least three directors, including all
of  the  external  directors,  one  of  whom  must  serve  as  chairman  of  the  committee.  In  accordance  with  the  exemption  available  to  certain  Israeli  public
companies, whose shares are traded on NASDAQ, we chose as of November 7, 2016 and for as long the required conditions precedent are met and unless
otherwise decided by our board of directors, not to follow the requirements of Companies Law with regard to the composition of the audit committee, and
instead, will follow the NASDAQ rules applicable to US domestic companies with respect to the appointment and composition of the audit committee.

Under the NASDAQ listing requirements, we are required to maintain an audit committee consisting of at least three independent directors, all of whom are
financially  literate  and  at  least  one  of  whom  has  accounting  or  related  financial  management  expertise.  Our  audit  committee  consists  of  Mr.  David
Hastings, Ms. Ruth Alon and Dr. Shmuel (Muli) Ben Zvi and is chaired by Mr. Hastings. Mr. Hastings and Dr. Ben Zvi are the audit committee financial
experts as defined by the Securities and Exchange Commission rules and all of the members of our audit committee have the requisite financial literacy as
defined by the NASDAQ Stock Market rules. All the members of our audit committee are “independent” as such term is defined in Rule 10A-3(b)(1) under
the Exchange Act and under the listing standards of NASDAQ.

Table of Contents

Our  board  of  directors  has  adopted  an  audit  committee  charter  setting  forth  the  responsibilities  of  the  audit  committee  consistent  with  the  rules  of  the
Securities  and  Exchange  Commission  and  NASDAQ  rules  as  well  as  the  requirements  for  such  committee  under  the  Companies  Law,  including  the
following:

●

●

●

oversight of our independent registered public accounting firm and recommending the engagement, compensation or termination of engagement of
our independent registered public accounting firm to the board of directors in accordance with Israeli law;

recommending the engagement or termination of the person filling the office of our internal auditor; and

recommending the terms of audit and non-audit services provided by the independent registered public accounting firm for pre-approval by our
board of directors.

Our  audit  committee  provides  assistance  to  our  board  of  directors  in  fulfilling  its  legal  and  fiduciary  obligations  in  matters  involving  our  accounting,
auditing, financial reporting, internal control and legal compliance functions by pre-approving the services performed by our independent accountants and
reviewing their reports regarding our accounting practices and systems of internal control over financial reporting. Our audit committee also oversees the
audit  efforts  of  our  independent  accountants  and  takes  those  actions  that  it  deems  necessary  to  satisfy  itself  that  the  accountants  are  independent  of
management.

Under the Companies Law, our audit committee is responsible for:

●

●

●

●

●

●

●

determining  whether  there  are  deficiencies  in  our  business  management  practices,  including  in  consultation  with  our  internal  auditor  or  the
independent auditor, and making recommendations to the board of directors to improve such practices;

determining whether  to  approve  certain  related  party  transactions  (including  transactions  in  which  an  office  holder  has  a  personal  interest)  and
whether such transaction is extraordinary or material under the Companies Law (see “-Approval of Related Party Transactions Under Israeli Law”);

where the  board  of  directors  approves  the  work  plan  of  the  internal  auditor,  to  examine  such  work  plan  before  its  submission  to  the  board  and
propose amendments thereto;

establishing  the  approval  process  for  certain  transactions  with  a  controlling  shareholder  or  in  which  a  controlling  shareholder  has  a  personal
interest;

examining our  internal  controls  and  internal  auditor’s  performance,  including  whether  the  internal  auditor  has  sufficient  resources  and  tools  to
dispose of its responsibilities;

examining the scope of our independent auditor’s work and compensation and submitting a recommendation with respect thereto to our board of
directors or shareholders, depending on which of them is considering the appointment of our auditor; and

establishing procedures for the handling of employees’ complaints as to deficiencies in the management of our business and the protection to be
provided to such employees.

Our audit committee may not approve any actions requiring its approval (see- “Approval of Related Party Transactions Under Israeli Law”), unless at the
time of approval a majority of the committee’s members are present, which majority consists of unaffiliated directors.

Compensation Committee

Our compensation committee consists of Dr. Ben Shapiro, of Marc Kozin, of Dr. Shmuel Ben-Zvi and of Dr. Ruth Arnon. Dr. Ben Shapiro serves as the
chairman of the compensation committee. The members of our compensation committee are independent under the NASDAQ listing requirements.

Under  the  Companies  Law,  the  board  of  directors  of  a  public  company  must  appoint  a  compensation  committee.  In  accordance  with  the  exemption
available  to  certain  Israeli  public  companies,  whose  shares  are  traded  on  NASDAQ,  we  chose  as  of  November  7,  2016  and  for  as  long  the  required
conditions precedent are met and unless otherwise decided by our board of directors, not to follow the requirements of Companies Law with regard to the
composition  of  the  compensation  committee,  and  instead,  will  follow  the  NASDAQ  rules  applicable  to  US  domestic  companies  with  respect  to  the
appointment and composition of the compensation committee.

64

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Table of Contents

The duties of the compensation committee include the recommendation to our board of directors of a policy regarding the terms of engagement of office
holders,  to  which  we  refer  as  a  compensation  policy.  That  policy  must  be  adopted  by  the  company’s  board  of  directors,  after  considering  the
recommendations  of  the  compensation  committee,  and  will  need  to  be  brought  every  three  years  for  approval  by  the  company’s  shareholders,  which
approval requires what we refer to as a special majority. A special majority approval requires shareholder approval by a majority vote of the shares present
and voting at a meeting of shareholders called for such purpose, provided that either: (a) such majority includes at least a majority of the shares held by all
shareholders who are not controlling shareholders and do not have a personal interest in such compensation arrangement; or (b) the total number of shares
of  non-controlling  shareholders  and  shareholders  who  do  not  have  a  personal  interest  in  the  compensation  arrangement  and  who  vote  against  the
arrangement does not exceed 2% of the company’s aggregate voting rights. On December 30, 2019, our shareholders approved our compensation policy for
an additional three-year term.

Our compensation policy must serve as the basis for decisions concerning the financial terms of employment or engagement of office holders, including
exculpation, insurance, indemnification or any monetary payment or obligation of payment in respect of employment or engagement. The compensation
policy  must  relate  to  certain  factors,  including  advancement  of  the  company’s  objectives,  the  company’s  business  plan  and  its  long  term  strategy,  and
creation  of  appropriate  incentives  for  office  holders.  It  must  also  consider,  among  other  things,  the  company’s  risk  management,  size  and  nature  of  its
operations. The term office holder is defined under the Companies Law as the general manager, chief executive officer, chief business manager, deputy
general manager, vice general manager, any other person assuming the responsibilities of any of these positions regardless of that person’s title, a director,
or a manager directly subordinate to the general manager. The compensation policy must furthermore consider the following additional factors:

●

●

●

●

●

●

●

the knowledge, skills, expertise, and accomplishments of the relevant office holder;

the office holder’s roles and responsibilities and prior compensation agreements with him or her;

the relationship between the terms offered and the average compensation of the other employees of the company, including those employed through
manpower companies;

the impact of disparities in salary upon work relationships in the company;

the possibility of reducing variable compensation at the discretion of the board of directors;

the possibility of setting a limit on the exercise value of non-cash variable equity-based compensation; and

as to  severance  compensation,  the  period  of  service  of  the  office  holder,  the  terms  of  his  or  her  compensation  during  such  service  period,  the
company’s  performance  during  that  period  of  service,  the  person’s  contributions  towards  the  company’s  achievement  of  its  goals  and  the
maximization of its profits, and the circumstances under which the person is leaving the company.

The compensation policy must also include the following principles:

●

●

●

●

●

the link between variable compensation and long term performance and measurable criteria;

the relationship between variable and fixed compensation, and the ceiling for the value of variable compensation;

the conditions under which an office holder would be required to repay compensation paid to him or her if it was later shown that the data upon
which such compensation was based was inaccurate and was required to be restated in the company’s financial statements;

the minimum holding or vesting period for variable, equity-based compensation; and

maximum limits for severance compensation.

The  compensation  committee  is  responsible  for  (a)  recommending  the  compensation  policy  to  a  company’s  board  of  directors  for  its  approval  (and
subsequent approval by its shareholders) and (b) duties related to the compensation policy and to the compensation of a company’s office holders as well as
functions previously fulfilled by a company’s audit committee with respect to matters related to approval of the terms of engagement of office holders,
including:

●

●

●

●

●

●

●

recommending whether a compensation policy should continue in effect, if the then- current policy has a term of greater than three years (approval
of either a new compensation policy or the continuation of an existing compensation policy must in any case occur every three years);

recommending to the board of directors periodic updates to the compensation policy;

assessing implementation of the compensation policy; and

determining whether the compensation terms of the chief executive officer of the company need not be brought to approval of the shareholders.
Our board of directors has adopted a compensation committee charter setting forth the responsibilities of the committee, which include:

the responsibilities set forth in the compensation policy;

reviewing and approving the granting of options and other incentive awards to the extent such authority is delegated by our board of directors; and

reviewing, evaluating and making recommendations regarding the compensation and benefits for our non-employee directors.

Nominating and Corporate Governance Committee

Shapiro.  Each  of  the  members  of  our  nominating  and  corporate  governance  committee,  except  for  Prof.  Harats  are  independent  under  the  listing
requirements of The NASDAQ Global Market.

Our  board  of  directors  has  adopted  a  nominating  and  governance  committee  charter  sets  forth  the  responsibilities  of  the  nominating  and  governance
committee which include:

assessing the performance of the members of our board; and

establishing and maintaining effective corporate governance policies and practices, including, but not limited to, developing and recommending to
our board a set of corporate governance guidelines applicable to our company.

Internal Auditor

Under  the  Companies  Law,  the  board  of  directors  of  a  public  company  must  appoint  an  internal  auditor  based  on  the  recommendation  of  the  audit
committee. The role of the internal auditor is to examine, among other things, our compliance with applicable law and orderly business procedures. The
audit committee is required to oversee the activities and to assess the performance of the internal auditor as well as to review the internal auditor’s work
plan. Our internal auditor is Mr. Zachi Refaeli from Ernst & Young Israel.

An internal auditor may not be:

●

●

●

●

a person (or a relative of a person) who holds more than 5% of the company’s outstanding shares or voting rights;

a person (or a relative of a person) who has the power to appoint a director or the general manager of the company;

an office holder or director of the company; or

Approval of Related Party Transactions Under Israeli Law

Fiduciary Duties of Directors and Executive Officers

The  Companies  Law  codifies  the  fiduciary  duties  that  office  holders  owe  to  a  company.  Each  person  listed  in  the  table  under  “Management-Executive
Officers and Directors” is an office holder under the Companies Law.

An office holder’s fiduciary duties consist of a duty of care and a duty of loyalty. The duty of care requires an office holder to act with the level of care with
which a reasonable office holder in the same position would have acted under the same circumstances. The duty of loyalty requires that an office holder act
in good faith and in the best interests of the company.

The duty of care includes a duty to use reasonable means to obtain:

●

●

information on the advisability of a given action brought for his or her approval or performed by virtue of his or her position; and

all other important information pertaining to these actions.

The duty of loyalty includes a duty to:

●

●

●

●

refrain from any conflict of interest between the performance of his or her duties to the company and his or her other duties or personal affairs;

refrain from any activity that is competitive with the company;

refrain from exploiting any business opportunity of the company to receive a personal gain for himself or herself or others; and

disclose to the company any information or documents relating to the company’s affairs which the office holder received as a result of his or her
position as an office holder.

Disclosure of Personal Interests of an Office Holder and Approval of Certain Transactions

The Companies Law requires that an office holder promptly disclose to the company any personal interest that he or she may be aware of and all related
material information or documents concerning any existing or proposed transaction by the company. An interested office holder’s disclosure must be made
promptly and in any event no later than the first meeting of the board of directors at which the transaction is considered. An office holder is not obliged to
disclose a personal interest if it derives solely from the personal interest of his or her relative in a transaction that is not considered as an extraordinary
transaction.

A “personal interest” is defined under the Companies Law to include a personal interest of any person in an act or transaction of a company, including the
personal interest of such person’s relative or of a corporate body in which such person or a relative of such person is a 5% or greater shareholder, director or
general manager or in which he or she has the right to appoint at least one director or the general manager, but excluding a personal interest stemming from
one’s ownership of shares in the company.

A personal interest furthermore includes the personal interest of a person for whom the office holder holds a voting proxy or the personal interest of the
office holder with respect to his or her vote on behalf of a person for whom he or she holds a proxy even if such shareholder has no personal interest in the
matter.  An  office  holder  is  not,  however,  obliged  to  disclose  a  personal  interest  if  it  derives  solely  from  the  personal  interest  of  his  or  her  relative  in  a
transaction that is not considered an extraordinary transaction.

Under the Companies Law, an extraordinary transaction is defined as any of the following:

●

●

●

a transaction other than in the ordinary course of business;

a transaction that is not on market terms; or

a transaction that may have a material impact on the company’s profitability, assets or liabilities.

If it is determined that an office holder has a personal interest in a transaction, approval by the board of directors is required for the transaction, unless the
company’s articles of association provide for a different method of approval. Further, so long as an office holder has disclosed his or her personal interest in
a transaction, the board of directors may approve an action by the office holder that would otherwise be deemed a breach of duty of loyalty. However, a
company may not approve a transaction or action that is adverse to the company’s interest or that is not performed by the office holder in good faith. An
extraordinary transaction in which an office holder has a personal interest requires approval first by the company’s audit committee and subsequently by the
board  of  directors.  The  compensation  of,  or  an  undertaking  to  indemnify  or  insure,  an  office  holder  who  is  not  a  director  requires  approval  first  by  the
company’s compensation committee, then by the company’s board of directors, and, if such compensation arrangement or an undertaking to indemnify or
insure is inconsistent with the company’s stated compensation policy or if the office holder is the chief executive officer (apart from a number of specific
exceptions), then such arrangement is subject to a special majority approval. Arrangements regarding the compensation, indemnification or insurance of a
director  require  the  approval  of  the  compensation  committee,  board  of  directors  and  shareholders  by  ordinary  majority,  in  that  order,  and  under  certain
circumstances, a special majority approval. If shareholders of a company do not approve the compensation terms of office holders, other than directors, but
including  the  chief  executive  officer,  the  compensation  committee  and  board  of  directors  may  override  the  shareholders’  decision,  subject  to  certain
conditions.

Generally, a person who has a personal interest in a matter which is considered at a meeting of the board of directors or the audit committee may not be
present at such a meeting or vote on that matter unless the chairman of the relevant committee or board of directors (as applicable) determines that he or
she should be present in order to present the transaction that is subject to approval. If a majority of the members of the audit committee or the board of
directors (as applicable) has a personal interest in the approval of a transaction, then all directors may participate in discussions of the audit committee or
the board of directors (as applicable) on such transaction and the voting on approval thereof, but shareholder approval is also required for such transaction.

Disclosure of Personal Interests of Controlling Shareholders and Approval of Certain Transactions

Pursuant to Israeli law, the disclosure requirements regarding personal interests that apply to directors and executive officers also apply to a controlling
shareholder of a public company. See “-Major Shareholders and Related Party Transactions” for a definition of controlling shareholder. In the context of a
transaction involving a shareholder of the company, a controlling shareholder also includes a shareholder who holds 25% or more of the voting rights in the
company if no other shareholder holds more than 50% of the voting rights in the company. For this purpose, the holdings of all shareholders who have a
personal interest in the same transaction will be aggregated. The approval of the audit committee, the board of directors and a special majority, in that order,
is required for (a) extraordinary transactions with a controlling shareholder or in which a controlling shareholder has a personal interest, (b) the engagement
with a controlling shareholder or his or her relative, directly or indirectly, for the provision of services to the company, (c) the terms of engagement and
compensation of a controlling shareholder or his or her relative who is not an office holder or (d) the employment of a controlling shareholder or his or her
relative by the company, other than as an office holder.

To the extent that any such transaction with a controlling shareholder is for a period extending beyond three years, approval is required once every three
years, unless, with respect to certain transactions, the audit committee determines that the duration of the transaction is reasonable given the circumstances
related thereto.

Arrangements regarding the compensation, indemnification or insurance of a controlling shareholder in his or her capacity as an office holder require the
approval of the compensation committee, board of directors and shareholders by a special majority and the terms thereof may not be inconsistent with the
company’s stated compensation policy.

Pursuant to regulations promulgated under the Companies Law, certain transactions with a controlling shareholder or his or her relative, or with directors,
that  would  otherwise  require  approval  of  a  company’s  shareholders  may  be  exempt  from  shareholder  approval  upon  certain  determinations  of  the  audit
committee and board of directors. Under these regulations, a shareholder holding at least 1% of the issued share capital of the company may require, within
14 days of the publication of such determinations, that despite such determinations by the audit committee and the board of directors, such transaction will
require shareholder approval under the same majority requirements that would otherwise apply to such transactions.

Employment Agreements with Executive Officers and Directors

We have entered into written employment agreements with each of Dror Harats, Erez Feige, Amos Ron, Tami Rachmilewitz, Eyal Breitbart and Naamit
Sher. All such agreements contain provisions regarding non-competition, confidentiality of information and assignment of inventions. The non-competition
provisions apply for a period of 24 months following termination of the respective officer’s employment. In addition, we are required to provide notice of
between three and six months prior to terminating the employment of such executive officers other than in the case of a termination for cause. Other than
with respect to Prof. Harats, these agreements do not provide for benefits upon the termination of these executives’ respective employment with us, other
than payment of salary and benefits during the required notice period for termination of these agreements, which varies under these individual agreements.
Prof. Harats’s agreement provides for six months of severance in the event Prof. Harats’s employment is terminated by us without cause or terminated by
Prof.  Harats  for  good  reason.  Pursuant  to  his  employment  agreement,  “Cause”  means  Prof.  Harats’s  conviction  of  any  felony  related  to  our  business,  a
serious  breach  of  trust  by  Prof.  Harats,  including  theft,  embezzlement  of  our  funds,  self-dealing,  prohibited  disclosure  of  confidential  or  proprietary
information and Prof. Harats’s engagement in any prohibited business competitive to our own, Prof. Harats’s disregard of lawful instructions of our board
of directors with respect to his duties to us following notice, or Prof. Harats’s willful failure to perform any of his fundamental functions or duties. Pursuant
to  his  employment  agreement,  “Good  reason”  means  a  material  reduction  in  Prof.  Harats’s  status,  title,  position  or  responsibilities,  a  reduction  in  Prof.
Harats’s salary which is not part of a general reduction in salary applicable to all of our employees, a failure by us to continue any material compensation or
benefit  plan,  program  or  practice  in  which  Prof.  Harats  is  participating,  or  a  material  breach  by  us  of  any  provision  of  Prof.  Harats’s  employment
agreement.

In addition, we have entered into compensation agreements with certain of our directors. The amounts payable pursuant to these arrangements have been
approved by our board of directors and shareholders.

Our  directors  do  not  receive  compensation  for  their  service  as  our  directors  or  otherwise,  unless  such  compensation  is  approved  by  our  compensation
committee, and then by the board of directors followed by the shareholders. The compensation of our directors may be fixed, as an all-inclusive payment or
as payment for participation in meetings, or as a combination thereof. In addition, such compensation may include: (i) in the case of a director who is also
an officer, a salary or other compensation in respect of his or her work as an officer, as may be agreed upon by the director and us; and (ii) reimbursement
of expenses, including travel expenses, expended in connection with his or her duties as a member of the board of directors.

Employees

As of March 1, 2021, we employed 38 employees, including 30 in research and development, and 8 in general and administrative positions, and of which
12 employees have either MDs or PhDs. All of our employees are located in Israel. We believe our employee relations are good.

Israeli  labor  laws  govern  the  length  of  the  workday,  minimum  wages  for  employees,  procedures  for  hiring  and  dismissing  employees,  determination  of
severance pay, annual leave, sick days, advance notice of termination of employment, equal opportunity and anti- discrimination laws and other conditions
of employment. Subject to specified exceptions, Israeli law generally requires severance pay upon the retirement, death or dismissal of an employee, and
requires  us  and  our  employees  to  make  payments  to  the  National  Insurance  Institute,  which  is  similar  to  the  U.S.  Social  Security  Administration.  Our
employees have defined benefit pension plans that comply with the applicable Israeli legal requirements.

None of our employees currently work under any collective bargaining agreements.

Share Ownership

For information regarding the share ownership of our directors and executive officers, please refer to “-Equity Compensation Plans” below and “Item 7.
Major Shareholders and Related Party Transactions-Major Shareholders.”

As of March 1, 2021, our directors and executive officers hold, in the aggregate, options, warrants and RSU’s outstanding for 5,348,588 ordinary shares.

These options have an average exercise price of $2.22 per share and have expiration dates generally twenty years after the grant date of the option.

2,963,942 options and warrants are exercisable as of March 1, 2021 and have a weighted average exercise price of $2.95 per share.

Equity Compensation Plans

The 2000 Plan, the 2011 Plan and the 2014 Plan, allow us to grant options to purchase our ordinary shares to our directors, officers, employees, consultants,
advisers and service providers. The option plans are intended to enhance our ability to attract and retain desirable individuals by increasing their ownership
interests in us. We no longer intend to grant options under the 2000 Plan or the 2011 Plan, and the remaining shares reserved for future grants under the
option plans will constitute the initial share reserve for the 2014 Plan. Additionally, upon the expiration of options granted under the 2000 Plan or the 2011
Plan, the ordinary shares underlying such expired options will increase the pool reserved for allocation under the 2014 Plan. As of March 1, 2021, we had
reserved  an  aggregate  of  9,507,693  ordinary  shares  under  the  option  plans.  As  of  March  1,  2021,  options  and  warrants  to  purchase  an  aggregate  of
7,527,126 ordinary shares were outstanding and options to purchase 650,993 ordinary shares had been exercised.

The plans are designed to reflect the provisions of the Israeli Income Tax Ordinance [New Version]-1961, as amended, mainly Sections 102 and 3(i), of the
Ordinance, which affords certain tax advantages to Israeli employees, officers and directors that are granted options in accordance with its terms.

Section  102  of  the  Ordinance  allows  employees,  directors  and  officers,  who  are  not  controlling  shareholders  and  who  are  Israeli  residents,  to  receive
favorable  tax  treatment  for  compensation  in  the  form  of  shares  or  options.  Section  102  of  the  Ordinance  includes  two  alternatives  for  tax  treatment
involving the issuance of options or shares to a trustee for the benefit of the grantees and also includes an additional alternative for the issuance of options
or shares directly to the grantee. Section 102(b)(2) of the Ordinance, which provides the most favorable tax treatment for grantees, permits the issuance to a
trustee under the “capital gains track.” In order to comply with the terms of the capital gains track, all options granted under a specific plan and subject to
the  provisions  of  Section  102  of  the  Ordinance,  as  well  as  the  shares  issued  upon  exercise  of  such  options  and  other  shares  received  following  any
realization of rights with respect to such options, such as share dividends and share splits, must be registered in the name of a trustee selected by the board
of directors and held in trust for the benefit of the relevant employee, director or officer. The trustee may not release these options or shares to the relevant
grantee before the second anniversary of the registration of the options in the name of the trustee. However, under this track, we are not allowed to deduct
an expense with respect to the issuance of the options or shares. Section 3(i) does not provide for a similar tax benefit.

The plans may be administered by our board of directors either directly or upon the recommendation of a committee appointed by our board of directors.

The compensation committee recommends to the board of directors, and the board of directors determines or approves the eligible individuals who receive
options under the plans, the number of ordinary shares covered by those options, the terms under which such options may be exercised, and other terms and
conditions of the options, all in accordance with the provisions of the plans. Option holders may not transfer their options except in the event of death or if
the compensation committee determines otherwise. Our compensation committee or board of directors may at any time amend or terminate each of the
plans; however, any amendment or termination may not adversely affect any options or shares granted under such plan prior to such action.

The option exercise price is determined by the compensation committee and specified in each option award agreement. In general, the option exercise price
is the fair market value of the shares on the date of grant as determined in good faith by our board of directors.

Employee Share Ownership and Option Plan (2014)

In June 2014, we adopted and obtained shareholder approval for our 2014 Plan and the U.S. Appendix thereto. The 2014 Plan provides for the grant of
options,  restricted  shares,  restricted  share  units  and  other  share-  based  awards  to  our  directors,  employees,  officers,  consultants,  advisors  and  service
providers, among others and to any other person whose services are considered valuable to us. Following the approval of the 2014 Plan by the Israeli tax
authorities, we will only grant options or other equity incentive awards under the 2014 Plan, although previously-granted options and awards will continue
to be governed by our 2000 Plan and 2011 Plan. The initial reserved pool under the 2014 Plan was 928,288 ordinary shares, and was adjusted as set forth in
the 2014 Plan, including an automatic annual increase on January 1 of each year such that the number of shares issuable under the 2014 Plan will equal 4%
of  our  issued  and  outstanding  share  capital  on  a  fully  diluted  basis  on  each  such  January  1,  or  a  lesser  number  of  shares  determined  by  the  board  of
directors. As of March 1, 2021, the outstanding reserved pool under the 2014 Plan stands on 1,969,999.

The 2014 Plan is administered by our board of directors or by a committee designated by the board of directors, which shall determine, subject to Israeli
law, the grantees of awards and the terms of the grant, including, exercise prices, vesting schedules, acceleration of vesting and the other matters necessary
in  the  administration  of  the  2014  Plan.  The  2014  Plan  enables  us  to  issue  awards  under  various  tax  regimes  including,  without  limitation,  pursuant  to
Sections  102  and  3(i)  of  the  Ordinance,  and  under  Section  422  of  the  Code.  Options  granted  under  the  2014  Plan  to  U.S.  residents  may  qualify  as
“incentive stock options” within the meaning of Section 422 of the Code, or may be non-qualified. The exercise price for “incentive stock options” must
not be less than the fair market value on the date on which an option is granted, or 110% of the fair market value if the option holder holds more than 10%
of our share capital.

We  currently  intend  to  grant  awards  under  the  2014  Plan  only  to  our  employees,  directors  and  officers  who  are  not  controlling  shareholders  and  are
considered Israeli residents, under the capital gains track of Section 102(b)2 of the Ordinance.

Awards under the 2014 Plan may be granted until June 8, 2034, 20 years from the date on which the 2014 Plan was approved by our board of directors,
provided that awards granted to any U.S. participants may be granted until June 8, 2024, 10 years from the date on which the 2014 Plan was approved by
our board of directors.

The options granted under the 2014 Plan generally vest over four years commencing on the date of grant such that 25% vest on the first anniversary of the
date of grant and an additional 6.25% vest at the end of each subsequent three-month period thereafter for 36 months. Options, other than certain incentive
share options, that are not exercised within 20 years from the grant date expire, unless otherwise determined by our board of directors or its designated
committee, as applicable. Share options that qualify as “incentive stock options” granted to a person holding more than 10% of our voting power under the
U.S. appendix to the 2014 Plan will expire within five years from the date of the grant and any other options granted under the U.S. appendix to the 2014
Plan will expire within 10 years from the date of grant. Except as otherwise determined by the board of directors or as set forth in an individual’s award
agreement, in the event of termination of employment or services for reasons of disability or death, or retirement, the grantee, or in the case of death, his or
her legal successor, may exercise options that have vested prior to termination within a period of one year from the date of disability or death, or within 180
days following retirement. If we terminate a grantee’s employment or service for cause, all of the grantee’s vested and unvested options will expire on the
date of termination. If a grantee’s employment or service is terminated for any other reason, the grantee may exercise his or her vested options within 90
days of the date of termination. Any expired or unvested options return to the pool for reissuance.

In the event of a merger or consolidation of our company, or a sale of all, or substantially all, of our shares or assets or other transaction having a similar
effect on us, then without the consent of the option holder, our board of directors may determine, at its absolute discretion, whether outstanding awards held
by  or  for  the  benefit  of  any  grantee  and  which  have  not  yet  vested,  is  to  be  assumed  or  substituted  and  whether  acceleration  of  such  awards  will  be
available.

Employee Share Ownership and Option Plan (2011)

In April  2011,  we  adopted  the  2011  Plan.  The  term  of  the  2011  Plan  is  twenty  years.  Each  option  granted  under  the  2011  Plan  entitles  the  grantee  to
purchase  our  ordinary  shares.  The  options  granted  under  the  2011  Plan  generally  vest  during  a  four-year  period  following  the  date  of  the  grant  in  13
installments: 25% of the options vest one year following the grant date, and additional 1/16 of the options vest at the end of each subsequent quarter over
the course of the following three years. The options expire twenty years after the date of grant if not exercised earlier.

In the case of certain changes in our share capital structure, such as a consolidation or share split or dividend, appropriate adjustments will be made to the
numbers of shares and exercise prices under outstanding options. Unless otherwise determined by the board of directors, upon the consummation of certain
kinds of transactions, such as a liquidation, a merger, reorganization or sale of all or substantially all of our assets, any unexercised outstanding options
shall expire, provided that in case of merger or consolidation or the sale, transfer or exchange of all or substantially all our assets or shares, the surviving
corporation does not assume the options or substitute them with appropriate options in the surviving corporation.

In general, when an option holder’s employment or service with us terminates, his or her option will no longer continue to vest following termination, and
the  holder  may  exercise  any  vested  options  for  a  period  of  90  days  following  termination  without  cause.  If  an  option  holder’s  employment  with  us
terminates due to disability (as determined by the board of directors) or if the termination of employment results from his or her death, then the option
holder or his or her estate (as applicable) has twelve months to exercise the option. If an option holder retires from our company, then, with the approval of
the board of directors, the option holder or his or her estate (as applicable) has six months to exercise the option. If termination of employment results from
cause, his or her outstanding options will expire upon termination. No option may be exercised after its scheduled expiration date.

Employee Share Ownership and Option Plan (2000)

In February 2000, we adopted the 2000 Plan, which was amended and restated in 2003 due to changes in applicable tax law. The original term of the 2000
Plan was ten years. In 2013, the terms of outstanding options were extended by 10 years.

Each option granted under the 2000 Plan entitles the grantee to purchase one of our ordinary shares. The options granted under the 2000 Plan generally vest
during  a  four-year  period  following  the  date  of  the  grant  in  three  installments:  50%  of  the  options  vest  two  years  following  the  grant  date,  25%  of  the
options vest three years following the grant date and the remaining 25% of the options vest four years following the grant date. The options under the plan
expire ten years after the date of grant if not exercised earlier.

In the case of certain changes in our share capital structure, such as a consolidation or share split or dividend, appropriate adjustments will be made to the
numbers of shares and exercise prices under outstanding options. In the event of certain transactions, such as an acquisition, or a merger or reorganization
or a sale of all or substantially all of our assets, there shall be an acceleration of exercise of unvested options, immediate or otherwise, which depends on,
among  other  things,  the  nature  of  such  transaction,  and  provided  that  in  case  of  merger  or  consolidation  the  surviving  corporation  does  not  assume  the
options or substitute them with appropriate options in the surviving corporation.

In general, when an option holder’s employment or service with us terminates, his or her option will no longer continue to vest following termination, and
the  holder  may  exercise  any  vested  options  for  a  period  of  90  days  following  termination  without  cause.  If  an  option  holder’s  employment  with  us
terminates due to disability (as determined by the board of directors) or if the termination of employment results from his or her death or due to retirement
after age 60, then with the approval of the board of directors, the option holder or his or her estate (as applicable) has twelve months to exercise the option;
however,  the  option  may  not  be  exercised  after  its  scheduled  expiration  date.  If  termination  of  employment  results  from  cause,  his  or  her  outstanding
options will expire upon termination.

Item 7. Major Shareholders and Related Party Transactions

Major Shareholders

The following table sets forth information with respect to the beneficial ownership of our ordinary shares as of February 1, 2021:

each person or entity known by us to own beneficially more than 5% of our outstanding ordinary shares;

each of our executive officers and directors individually; and

all of our executive officers and directors as a group.

●

●

●

The beneficial ownership of our ordinary shares is determined in accordance with the rules of the SEC and generally includes any shares over which a
person exercises sole or shared voting or investment power, or the right to receive the economic benefit of ownership. For purposes of the table below, we
deem ordinary shares issuable pursuant to options that are currently exercisable or exercisable within 60 days of December 31, 2020 to be outstanding and
to be beneficially owned by the person holding the options for the purposes of computing the percentage ownership of that person, but we do not treat them
as outstanding for the purpose of computing the percentage ownership of any other person. The percentage of ordinary shares beneficially owned is based
on 55,134,735 ordinary shares outstanding as of March 1, 2021.

According to our transfer agent, as of February 14, 2021 there were 12 record holders of our ordinary shares, of which two record holders were located

in the United States. None of our shareholders has different voting rights from other shareholders.

Except as described in the footnotes below, we believe each shareholder has voting and investment power with respect to the ordinary shares indicated
in the table as beneficially owned. Unless otherwise indicated, the address of each beneficial owner is c/o Vascular Biogenics Ltd., 8 HaSatat St., Modi’in,
Israel 7178106.

Related Party Transactions

The following is a description of the material terms of those transactions with related parties to which we are party since January 1, 2019.

On December 30, 2019, our shareholders approved the extension of our written compensation policy for an additional three-year term. We have adopted a
written policy which provides that the approval of the audit committee is required to effect specified actions and transactions with our directors, executive
officers and controlling shareholders, or in which such persons have an interest. See “Item 6. Directors, Senior Management and Employees-Approval of
Related  Party  Transactions  Under  Israeli  Law.”  The  term  “controlling  shareholder”  means  a  shareholder  with  the  ability  to  direct  the  activities  of  our
company, other than by virtue of being an executive officer or director. A shareholder is presumed to be a controlling shareholder if the shareholder holds
50% or more of the voting rights in a company or has the right to appoint the majority of the directors of the company or its general manager. For the
purpose  of  approving  transactions  with  controlling  shareholders,  as  well  as  corporate  approval  of  executive  compensation,  the  term  also  includes  any
shareholder (or two or more shareholders having a personal interest in the same matter being brought for approval) that holds 25% or more of the voting
rights of a company if the company has no shareholder that owns more than 50% of its voting rights. The transactions described below were entered into
prior to the effectiveness of this policy.

Indemnification Agreements

We have in place indemnification agreements with each of our executive officers exculpating them from a breach of their duty of care to us to the fullest
extent permitted by law, subject to limited exceptions, and undertaking to indemnify them to the fullest extent permitted by Israeli law, subject to limited
exceptions, including with respect to liabilities resulting from the initial public offering to the extent such liabilities are not covered by insurance.

Employment Agreements

We have entered into employment agreements with our executive officers and key employees. The employment agreements contain standard provisions,
including  assignment  of  invention  provisions  and  non-competition  clauses.  See  “Item  6.  Directors,  Senior  Management  and  Employees-Employment
Agreements with Executive Officers.”

Item 8. Financial Information

Financial statements are set forth under Item 18.

We have never declared or paid any cash dividends to our shareholders. We currently anticipate that we will retain all of our future earnings, if any, for use
in  the  operation  of  our  business.  Additionally,  our  ability  to  pay  dividends  on  our  ordinary  shares  is  limited  by  restrictions  under  the  terms  of  the
agreements governing our indebtedness and under Israeli law.

Item 9. The Offer and Listing

Our ordinary shares are quoted on the Nasdaq Global Market under the symbol “VBLT.”

Nasdaq Global Market

Our ordinary shares began trading on the Nasdaq Global Market under the symbol “VBLT” on October 1, 2014.

Item 10. Additional Information

A. Share Capital

Not applicable.

B. Memorandum and Articles of Association

Ordinary Shares

Voting

All ordinary shares will have identical voting and other rights in all respects.

Transfer of Shares

Our fully paid ordinary shares are issued in registered form and may be freely transferred under our amended and restated articles of association, unless the
transfer  is  restricted  or  prohibited  by  another  instrument,  applicable  law  or  the  rules  of  a  stock  exchange  on  which  the  shares  are  listed  for  trade.  The
ownership or voting of our ordinary shares by non-residents of Israel is not restricted in any way by our amended and restated articles of association or the
laws of the State of Israel, except for ownership by nationals of some countries that are, or have been, in a state of war with Israel.

Election of Directors

Our ordinary shares do not have cumulative voting rights for the election of directors. As a result, the holders of a majority of the voting power represented
at a shareholders meeting have the power to elect all of our directors, subject to the special approval requirements for external directors described under
“Item 6. Directors, Senior Management and Employees-Board of Directors.”

Under our amended and restated articles of association, our board of directors must consist of not less than three, not including two external directors, but
no more than nine directors (including the external directors). Pursuant to our amended and restated articles of association, other than the external directors,
for whom special election requirements apply under the Companies Law, the vote required to appoint a director is a simple majority vote of holders of our
voting shares, participating and voting at the relevant meeting. Each director will serve until his or her successor is duly elected and qualified or until his or
her earlier death, resignation or removal by a vote of the majority voting power of our shareholders at a general meeting of our shareholders or until his or
her office expires by operation of law, in accordance with the Companies Law. In addition, our amended and restated articles of association allow our board
of directors to appoint directors to fill vacancies on the board of directors to serve for a term of office equal to the remaining period of the term of office of
the directors(s) whose office(s) have been vacated. External directors are elected for an initial term of three years, may be elected for additional terms of
three years each under certain circumstances, and may be removed from office pursuant to the terms of the Companies Law. See “Item 6. Directors, Senior
Management and Employees-Board of Directors.”

Dividend and Liquidation Rights

We  may  declare  a  dividend  to  be  paid  to  the  holders  of  our  ordinary  shares  in  proportion  to  their  respective  shareholdings.  Under  the  Companies  Law,
dividend distributions are determined by the board of directors and do not require the approval of the shareholders of a company unless the company’s
articles of association provide otherwise. Our amended and restated articles of association do not require shareholder approval of a dividend distribution
and provide that dividend distributions may be determined by our board of directors.

Pursuant to the Companies Law, the distribution amount is limited to the greater of retained earnings or earnings generated over the previous two years,
according to our then last reviewed or audited financial statements, provided that the date of the financial statements is not more than six months prior to
the date of the distribution, or we may otherwise only distribute dividends that do not meet such criteria only with court approval. In each case, we are only
permitted to distribute a dividend if our board of directors and the court, if applicable, determines that there is no reasonable concern that payment of the
dividend will prevent us from satisfying our existing and foreseeable obligations as they become due.

In the event of our liquidation, after satisfaction of liabilities to creditors, our assets will be distributed to the holders of our ordinary shares in proportion to
their shareholdings. This right, as well as the right to receive dividends, may be affected by the grant of preferential dividend or distribution rights to the
holders of a class of shares with preferential rights that may be authorized in the future.

Shareholder Meetings

Under Israeli law, we are required to hold an annual general meeting of our shareholders once every calendar year that must be held no later than 15 months
after the date of the previous annual general meeting. All meetings other than the annual general meeting of shareholders are referred to in our amended
and restated articles of association as extraordinary general meetings. Our board of directors may call extraordinary general meetings whenever it sees fit,
at such time and place, within or outside of Israel, as it may determine. In addition, the Companies Law provides that our board of directors is required to
convene an extraordinary general meeting upon the written request of (i) any two of our directors or one- quarter of the members of our board of directors
or (ii) one or more shareholders holding, in the aggregate, either (a) 5% or more of our outstanding issued shares and 1% of our outstanding voting power
or (b) 5% or more of our outstanding voting power. One or more shareholders, holding 1% or more of the outstanding voting power, may ask the board to
add an item to the agenda of a prospective meeting, if the proposal merits discussion at the general meeting.

Table of Contents

Subject  to  the  provisions  of  the  Companies  Law  and  the  regulations  promulgated  thereunder,  shareholders  entitled  to  participate  and  vote  at  general
meetings are the shareholders of record on a date to be decided by the board of directors, which may be between four and 40 days prior to the date of the
meeting.  Furthermore,  the  Companies  Law  requires  that  resolutions  regarding  the  following  matters  must  be  passed  at  a  general  meeting  of  our
shareholders:

●

●

●

●

●

●

●

amendments to our articles of association;

appointment or termination of our auditors;

appointment of external directors;

approval of certain related party transactions;

increases or reductions of our authorized share capital;

a merger; and

the exercise of our board of director’s powers by a general meeting, if our board of directors is unable to exercise its powers and the exercise of any
of its powers is required for our proper management.

The  Companies  Law  and  our  amended  and  restated  articles  of  association  require  that  a  notice  of  any  annual  general  meeting  or  extraordinary  general
meeting be provided to shareholders at least 21 days prior to the meeting and if the agenda of the meeting includes the appointment or removal of directors,
the approval of transactions with office holders or interested or related parties, or an approval of a merger, notice must be provided at least 35 days prior to
the meeting.

Under the Companies Law and our amended and restated articles of association, shareholders are not permitted to take action via written consent in lieu of
a meeting.

Quorum Requirements

Pursuant  to  our  amended  and  restated  articles  of  association,  holders  of  our  ordinary  shares  have  one  vote  for  each  ordinary  share  held  on  all  matters
submitted to a vote before the shareholders at a general meeting. As a foreign private issuer, the quorum required for our general meetings of shareholders
consists of at least two shareholders present in person, by proxy or written ballot who hold or represent between them at least 25% of the total outstanding
voting rights. A meeting adjourned for lack of a quorum is generally adjourned to the same day in the following week at the same time and place or to a
later time or date if so specified in the notice of the meeting. At the reconvened meeting, any two or more shareholders present in person or by proxy shall
constitute a lawful quorum.

Vote Requirements

Our amended and restated articles of association provide that all resolutions of our shareholders require a simple majority vote, unless otherwise required
by  the  Companies  Law  or  by  our  amended  and  restated  articles  of  association.  Under  the  Companies  Law,  each  of  (i)  the  approval  of  an  extraordinary
transaction with a controlling shareholder and (ii) the terms of employment or other engagement of the controlling shareholder of the company or such
controlling  shareholder’s  relative  (even  if  not  extraordinary)  requires,  the  approval  described  above  under  “Management-Approval  of  Related  Party
Transactions Under Israeli Law-Disclosure of Personal Interests of Controlling Shareholders and Approval of Certain Transactions.” Under our amended
and restated articles of association, the alteration of the rights, privileges, preferences or obligations of any class of our shares requires a simple majority
vote of the class so affected (or such other percentage of the relevant class that may be set forth in the governing documents relevant to such class), in
addition to the ordinary majority vote of all classes of shares voting together as a single class at a shareholder meeting. An exception to the simple majority
vote requirement is a resolution for the voluntary winding up, or an approval of a scheme of arrangement or reorganization, of the company pursuant to
Section 350 of the Companies Law, which requires the approval of holders of 75% of the voting rights represented at the meeting, in person, by proxy or by
voting deed and voting on the resolution.

Access to Corporate Records

Under  the  Companies  Law,  shareholders  are  provided  access  to:  minutes  of  our  general  meetings;  our  shareholders  register  and  principal  shareholders
register, articles of association and financial statements; and any document that we are required by law to file publicly with the Israeli Companies Registrar
or  the  Israel  Securities  Authority.  In  addition,  shareholders  may  request  to  be  provided  with  any  document  related  to  an  action  or  transaction  requiring
shareholder approval under the related party transaction provisions of the Companies Law. We may deny this request if we believe it has not been made in
good faith or if such denial is necessary to protect our interest or protect a trade secret or patent.

Acquisitions Under Israeli Law

Full Tender Offer

A person wishing to acquire shares of an Israeli public company and who would as a result hold over 90% of the target company’s issued and outstanding
share  capital  is  required  by  the  Companies  Law  to  make  a  tender  offer  to  all  of  the  company’s  shareholders  for  the  purchase  of  all  of  the  issued  and
outstanding shares of the company. A person wishing to acquire shares of a public Israeli company and who would as a result hold over 90% of the issued
and outstanding share capital of a certain class of shares is required to make a tender offer to all of the shareholders who hold shares of the relevant class
for the purchase of all of the issued and outstanding shares of that class. If the shareholders who do not accept the offer hold less than 5% of the issued and
outstanding share capital of the company or of the applicable class, and more than half of the shareholders who do not have a personal interest in the offer
accept the offer, all of the shares that the acquirer offered to purchase will be transferred to the acquirer by operation of law. However, a tender offer will
also be accepted if the shareholders who do not accept the offer hold less than 2% of the issued and outstanding share capital of the company or of the
applicable class of shares.

76

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Table of Contents

Upon a successful completion of such a full tender offer, any shareholder that was an offeree in such tender offer, whether such shareholder accepted the
tender offer or not, may, within six months from the date of acceptance of the tender offer, petition an Israeli court to determine whether the tender offer
was for less than fair value and that the fair value should be paid as determined by the court. However, under certain conditions, the offeror may include in
the terms of the tender offer that an offeree who accepted the offer will not be entitled to petition the Israeli court as described above.

If (a) the shareholders who did not respond or accept the tender offer hold at least 5% of the issued and outstanding share capital of the company or of the
applicable class or the shareholders who accept the offer constitute less than a majority of the offerees that do not have a personal interest in the acceptance
of the tender offer, or (b) the shareholders who did not accept the tender offer hold 2% or more of the issued and outstanding share capital of the company
(or of the applicable class), the acquirer may not acquire shares of the company that will increase its holdings to more than 90% of the company’s issued
and outstanding share capital or of the applicable class from shareholders who accepted the tender offer.

Special Tender Offer

The Companies Law provides that an acquisition of shares of an Israeli public company must be made by means of a special tender offer if as a result of the
acquisition the purchaser would become a holder of 25% or more of the voting rights in the company. This requirement does not apply if there is already
another holder of at least 25% of the voting rights in the company. Similarly, the Companies Law provides that an acquisition of shares in a public company
must be made by means of a special tender offer if, as a result of the acquisition, the purchaser would become a holder of more than 45% of the voting
rights in the company, provided that there is no other shareholder of the company who holds more than 45% of the voting rights in the company, subject to
certain exceptions.

A special tender offer must be extended to all shareholders of a company, but the offeror is not required to purchase shares representing more than 5% of
the voting power attached to the company’s outstanding shares, regardless of how many shares are tendered by shareholders. A special tender offer may be
consummated only if (i) outstanding shares representing at least 5% of the voting power of the company will be acquired by the offeror and (ii) the number
of shares tendered in the offer exceeds the number of shares whose holders objected to the offer (excluding the purchaser, controlling shareholders, holders
of 25% or more of the voting rights in the company or any person having a personal interest in the acceptance of the tender offer). If a special tender offer
is accepted, then the purchaser or any person or entity controlling it or under common control with the purchaser or such controlling person or entity may
not make a subsequent tender offer for the purchase of shares of the target company and may not enter into a merger with the target company for a period
of one year from the date of the offer, unless the purchaser or such person or entity undertook to effect such an offer or merger in the initial special tender
offer.

Merger

The  Companies  Law  permits  merger  transactions  if  approved  by  each  party’s  board  of  directors  and,  unless  certain  requirements  described  under  the
Companies Law are met, by a majority vote of each party’s shareholders, and, in the case of the target company, a majority vote of each class of its shares,
voted on the proposed merger at a shareholders meeting.

For purposes of the shareholder vote, unless a court rules otherwise, the merger will not be deemed approved if a majority of the votes of shares represented
at the shareholders meeting that are held by parties other than the other party to the merger, or by any person (or group of persons acting in concert) who
holds (or hold, as the case may be) 25% or more of the voting rights or the right to appoint 25% or more of the directors of the other party, vote against the
merger. If, however, the merger involves a merger with a company’s own controlling shareholder or if the controlling shareholder has a personal interest in
the merger, then the merger is instead subject to the same special majority approval that governs all extraordinary transactions with controlling shareholders
(as described under “Item 6. Directors, Senior Management and Employees-Disclosure of Personal Interests of Controlling Shareholders and Approval of
Certain Transactions”).

If the transaction would have been approved by the shareholders of a merging company but for the separate approval of each class or the exclusion of the
votes of certain shareholders as provided above, a court may still approve the merger upon the request of holders of at least 25% of the voting rights of a
company, if the court holds that the merger is fair and reasonable, taking into account the value of the parties to the merger and the consideration offered to
the shareholders of the target company.

Upon the request of a creditor of either party to the proposed merger, the court may delay or prevent the merger if it concludes that there exists a reasonable
concern  that,  as  a  result  of  the  merger,  the  surviving  company  will  be  unable  to  satisfy  the  obligations  of  the  merging  entities,  and  may  further  give
instructions to secure the rights of creditors.

In addition, a merger may not be consummated unless at least 50 days have passed from the date on which a proposal for approval of the merger was filed
by each party with the Israeli Registrar of Companies and at least 30 days have passed from the date on which the merger was approved by the shareholders
of each party.

Anti-takeover Measures

The  Companies  Law  allow  us  to  create  and  issue  shares  having  rights  different  from  those  attached  to  our  ordinary  shares,  including  shares  providing
certain  preferred  rights  with  respect  to  voting,  distributions  or  other  matters  and  shares  having  preemptive  rights.  No  preferred  shares  are  currently
authorized under our amended and restated articles of association. In the future, if we do authorize, create and issue a specific class of preferred shares,
such class of shares, depending on the specific rights that may be attached to it, may have the ability to frustrate or prevent a takeover or otherwise prevent
our  shareholders  from  realizing  a  potential  premium  over  the  market  value  of  their  ordinary  shares.  The  authorization  and  designation  of  a  class  of
preferred  shares  will  require  an  amendment  to  our  amended  and  restated  articles  of  association,  which  requires  the  prior  approval  of  the  holders  of  a
majority of the voting power attaching to our issued and outstanding shares at a general meeting. The convening of the meeting, the shareholders entitled to
participate and the majority vote required to be obtained at such a meeting will be subject to the requirements set forth in the Companies Law as described
above in “Voting Rights”.

Tax Law

Israeli tax law treats some acquisitions, such as stock-for-stock swaps between an Israeli company and a foreign company, less favorably than U.S. tax law.
For  example,  Israeli  tax  law  may  subject  a  shareholder  who  exchanges  ordinary  shares  in  an  Israeli  company  for  shares  in  a  non-Israeli  corporation  to
immediate taxation unless such shareholder receives authorization from the Israeli Tax Authority for different tax treatment.

Modification of Class Rights

Under the Companies Law and our amended and restated articles of association, the rights attached to any class of share, such as voting, liquidation and
dividend rights, may be amended by adoption of a resolution by the holders of a majority of the shares of that class present at a separate class meeting, or
otherwise in accordance with the rights attached to such class of shares, as set forth in our amended and restated articles of association.

Establishment

Our  registration  number  with  the  Israeli  Registrar  of  Companies  is  51-289976-6.  Our  purpose  as  set  forth  in  our  amended  and  restated  articles  of
association is to engage in any lawful activity.

Transfer Agent and Registrar

The transfer agent and registrar for our ordinary shares is American Stock Transfer & Trust Company, LLC.

C. Material Contracts

We have not entered into any material contracts other than in the ordinary course of business and other than those described in “Item 4. Information on the
Company”, “Item 6. Directors, Senior Management and Employees” or elsewhere in this Annual Report.

D. Exchange Controls

There  are  currently  no  Israeli  currency  control  restrictions  on  remittances  of  dividends  on  our  ordinary  shares,  proceeds  from  the  sale  of  the  shares  or
interest or other payments to non- residents of Israel, except for shareholders who are subjects of countries that are, or have been, in a state of war with
Israel.

In 1998, Israeli currency control regulations were liberalized significantly, so that Israeli residents generally may freely deal in foreign currency and foreign
assets, and non-residents may freely deal in Israeli currency and Israeli assets. There are currently no Israeli currency control restrictions on remittances of
dividends on the ordinary shares or the proceeds from the sale of the shares provided that all taxes were paid or withheld; however, legislation remains in
effect pursuant to which currency controls can be imposed by administrative action at any time.

Non-residents of Israel may freely hold and trade our securities. Neither our articles of association nor the laws of the State of Israel restrict in any way the
ownership or voting of ordinary shares by non-residents, except that such restrictions may exist with respect to citizens of countries which are in a state of
war with Israel. Israeli residents are allowed to purchase our ordinary shares.

E. Taxation

The following description is not intended to constitute a complete analysis of all tax consequences relating to the acquisition, ownership and disposition of
our ordinary shares. You should consult your own tax advisor concerning the tax consequences of your particular situation, as well as any tax consequences
that may arise under the laws of any state, local, foreign or other taxing jurisdiction.

Israeli Tax Considerations and Government Programs

The  following  is  a  brief  summary  of  the  material  Israeli  tax  laws  applicable  to  us,  and  certain  Israeli  Government  programs  that  may  benefit  us.  This
section  also  contains  a  discussion  of  material  Israeli  tax  consequences  concerning  the  ownership  and  disposition  of  our  ordinary  shares  purchased  by
investors.  This  summary  does  not  discuss  all  the  aspects  of  Israeli  tax  law  that  may  be  relevant  to  a  particular  investor  in  light  of  his  or  her  personal
investment circumstances or to some types of investors subject to special treatment under Israeli law. Examples of such investors include residents of Israel
or  traders  in  securities  who  are  subject  to  special  tax  regimes  not  covered  in  this  discussion.  Because  parts  of  this  discussion  are  based  on  new  tax
legislation that has not yet been subject to judicial or administrative interpretation, we cannot assure you that the appropriate tax authorities or the courts
will accept the views expressed in this discussion. The discussion below is subject to change, including due to amendments under Israeli law or changes to
the applicable judicial or administrative interpretations of Israeli law, which change could affect the tax consequences described below.

General Corporate Tax Structure in Israel

Israeli companies are generally subject to corporate tax, currently at the rate of 23% of a company’s taxable income. However, the effective tax rate payable
by a company that derives income from an Approved Enterprise, a Benefited Enterprise, a Preferred Enterprise or a Preferred Technology Enterprise (as
discussed below) may be considerably less. Capital gains derived by an Israeli company are generally subject to tax at the prevailing corporate tax rate.

Law for the Encouragement of Industry (Taxes), 5729-1969

The Law for the Encouragement of Industry (Taxes), 5729-1969, generally referred to as the Industry Encouragement Law, provides several tax benefits for
“Industrial Companies.”

The Industry Encouragement Law defines an “Industrial Company” as a company incorporated and resident in Israel, of which 90% or more of its income
in  any  tax  year,  other  than  income  from  defense  loans,  is  derived  from  an  “Industrial  Enterprise”  owned  by  it  that  is  located  in  Israel.  An  “Industrial
Enterprise” is defined as an enterprise whose principal activity in a given tax year is industrial production.

The following corporate tax benefits, among others, are available to Industrial Companies:

●

●

●

amortization over an eight-year period of the cost of patents and rights to use patents and know-how which were purchased in good faith and are
used for the development or advancement of the Industrial Enterprise;

under certain conditions, an election to file consolidated tax returns with related Israeli Industrial Companies; and

expenses related to a public offering are deductible in equal amounts over three years.

There is no assurance that we qualify as an Industrial Company or that the benefits described above are currently available to us or will be available to us in
the future.

Law for the Encouragement of Capital Investments, 5719-1959

The Law for the Encouragement of Capital Investments, 5719-1959, generally referred to as the Investment Law, provides certain incentives for capital
investments in productive assets, such as production facilities, by “Industrial Enterprises” (as defined under the Investment Law).

The Investment Law was significantly amended effective April 1, 2005 (the “2005 Amendment”), and further amended as of January 1, 2011 (the “2011
Amendment”)  and  as  of  January  1,  2017  (the  “2017  Amendment”).  Pursuant  to  the  2005  Amendment,  tax  benefits  granted  in  accordance  with  the
provisions of the Investment Law prior to its revision by the 2005 Amendment remain in force but any benefits granted subsequently are subject to the
provisions of the 2005 Amendment. Similarly, the 2011 Amendment introduced new benefits to replace those granted in accordance with the provisions of
the Investment Law in effect prior to the 2011 Amendment. However, companies entitled to benefits under the Investment Law as in effect prior to January
1, 2011 were entitled to choose to continue to enjoy such benefits, provided that certain conditions are met, or elect instead, irrevocably, to forego such
benefits and have the benefits of the 2011 Amendment apply. Finally, the 2017 Amendment provided another benefits track, which represents an alternative
to the tracks available under the 2005 Amendment and the 2011 Amendment. We have examined the possible effect, if any, of these provisions of the 2011
Amendment  and  the  2017  Amendment  on  our  financial  statements  and  have  decided,  at  this  time,  not  to  opt  to  apply  the  new  benefits  under  the  2011
Amendment or the 2017 Amendment.

Tax Benefits Prior to the 2005 Amendment

An  investment  program  that  is  implemented  in  accordance  with  the  provisions  of  the  Investment  Law  prior  to  the  2005  Amendment,  referred  to  as  an
“Approved Enterprise,” is entitled to certain benefits. A company that wished to receive benefits as an Approved Enterprise must have received approval
from the Investment Center of the Israeli Ministry of the Economy (formerly the Ministry of Industry, Trade and Labor), or the Investment Center. Each
certificate of approval for an Approved Enterprise relates to a specific investment program in the Approved Enterprise, delineated both by the financial
scope of the investment and by the physical characteristics of the facility or the asset.

79

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Table of Contents

In general, an Approved Enterprise is entitled to receive a grant from the Government of Israel or an alternative package of tax benefits, known as the
alternative benefits track. The tax benefits from any certificate of approval relate only to taxable income attributable to the specific Approved Enterprise.
Income derived from activity that is not integral to the activity of the Approved Enterprise does not enjoy tax benefits.

In addition, a company that has an Approved Enterprise program is eligible for further tax benefits if it qualifies as a Foreign Investors’ Company (“FIC”),
which is a company with a level of foreign investment, as defined in the Investment Law, of more than 25%. The level of foreign investment is measured as
the percentage of rights in the company (in terms of shares, rights to profits, voting and appointment of directors), and of combined share capital and loans,
that are owned, directly or indirectly, by persons who are not residents of Israel. The determination as to whether a company qualifies as an FIC is made on
an annual basis.

If a company elects the alternative benefits track and distributes a dividend out of income derived by its Approved Enterprise during the tax exemption
period it will be subject to corporate tax in respect of the amount of the dividend (grossed-up to reflect the pre-tax income that it would have had to earn in
order to distribute the dividend) at the corporate tax rate which would have been applicable without the tax exemption under the alternative benefits track.
In addition, dividends paid out of income attributed to an Approved Enterprise are generally subject to withholding tax at source at the rate of 15% or such
lower rate as may be provided in an applicable tax treaty.

The Investment Law also provides that an Approved Enterprise is entitled to accelerated depreciation on its property and equipment that are included in an
Approved Enterprise program during the first five years in which the equipment is used.

The benefits available to an Approved Enterprise are subject to the fulfillment of conditions stipulated in the Investment Law and its regulations and the
criteria in the specific certificate of approval. If a company does not meet these conditions, it would be required to repay the amount of tax benefits, as
adjusted by the Israeli consumer price index, and interest.

We do not have Approved Enterprise programs.

Tax Benefits Subsequent to the 2005 Amendment

The 2005 Amendment applies to new investment programs commencing after 2004, but does not apply to investment programs approved prior to April 1,
2005. The 2005 Amendment provides that terms and benefits included in any certificate of approval that was granted before the 2005 Amendment became
effective (April 1, 2005) will remain subject to the provisions of the Investment Law as in effect on the date of such approval.

The 2005 Amendment provides that a certificate of approval from the Investment Center will only be necessary for receiving cash grants. As a result, it was
no longer necessary for a company to obtain an Approved Enterprise certificate of approval in order to receive the tax benefits previously available under
the alternative benefits track. Rather, a company may claim the tax benefits offered by the alternative benefits track directly in its tax returns, provided that
it meets the criteria for tax benefits set forth in the amendment. In order to receive the tax benefits, the 2005 Amendment states, inter alia , that a company
must make an investment which meets all of the conditions, including a minimum qualifying investment in certain productive assets as specified in the
Investment Law. Such investment, along with the fulfillment of certain export requirements, allows a company to receive “Benefited Enterprise” status, and
may be made over a period of no more than three years culminating with the end of the Benefited Enterprise election year.

The extent of the tax benefits available under the 2005 Amendment to qualifying income of a Benefited Enterprise depends on, among other things, the
geographic location in Israel of the Benefited Enterprise. The location will also determine the period for which tax benefits are available. Such tax benefits
include  an  exemption  from  corporate  tax  on  undistributed  income  generated  by  the  Benefited  Enterprise  for  a  period  of  between  two  to  ten  years,
depending on the geographic location of the Benefited Enterprise in Israel, and a reduced corporate tax rate of between 10% to 25% for the remainder of
the benefits period, depending on the level of foreign investment in the company in each year. The benefits period is limited to 12 years from the beginning
of the Benefited Enterprise election year. With respect to an establishment Benefited Enterprise plan located in certain specific locations, the benefits period
is limited to 14 years from the beginning of the Benefited Enterprise election year, depending on the location of the Benefited Enterprise. We informed the
Israeli  Tax  Authority  of  our  choice  of  2012  as  a  Benefited  Enterprise  election  year. A  company  qualifying  for  tax  benefits  under  the  2005  Amendment
which pays a dividend out of income derived by its Benefited Enterprise during the tax exemption period will be subject to corporate tax in respect of the
amount of the dividend (grossed-up to reflect the pre-tax income that it would have had to earn in order to distribute the dividend) at the corporate tax rate
which would have otherwise been applicable. Dividends paid out of income attributed to a Benefited Enterprise are generally subject to withholding tax at
source at the rate of 15% or such lower rate as may be provided in an applicable tax treaty.

The  benefits  available  to  a  Benefited  Enterprise  are  subject  to  the  fulfillment  of  conditions  stipulated  in  the  Investment  Law  and  its  regulations.  If  a
company does not meet these conditions, in a given tax year during the benefits period, it would generally not be eligible for tax benefits during such tax
year; however, the company’s eligibility for tax benefits in prior and future years should not be impacted.

We currently have one Benefited Enterprise program under the Investments Law, which, we believe, may entitle us to certain tax benefits. The tax benefit
period  for  this  program  has  not  yet  commenced  but  is  expected  to  end  no  later  than  the  end  of  tax  year  2023.  During  the  benefits  period,  which  shall
commence with the year we will first earn taxable income relating to such enterprise, subject to the 12 years limitation described above, and shall run for a
period  of  up  to  10  years  (assuming  FIC  status),  a  corporate  tax  exemption  is  expected  to  apply  with  respect  to  the  taxable  income  from  our  Benefited
Enterprise program (once generated) generated during the first two years of the benefits period (so long as it remains undistributed) and reduced corporate
tax rates are expected to apply to such taxable income generated in the remaining years of the benefits period.

There is no assurance that our future taxable income will qualify as Benefited Enterprise income or that the benefits described above will be available to us
in the future.

Tax Benefits Under the 2011 Amendment

The 2011 Amendment canceled the availability of the benefits granted to companies under the Investment Law prior to 2011, subject to certain exceptions,
and, instead, introduced new benefits for income generated by a “Preferred Company” through its “Preferred Enterprise” (as such terms are defined in the
Investment Law) as of January 1, 2011. The definition of a Preferred Company includes a company incorporated in Israel that is not wholly-owned by a
governmental  entity,  and  that  has,  among  other  things,  Preferred  Enterprise  status  and  is  controlled  and  managed  from  Israel.  Pursuant  to  the  2011
Amendment,  in  2014  and  thereafter  a  Preferred  Company  is  entitled  to  a  reduced  corporate  tax  rate  of  16%  with  respect  to  its  income  derived  by  its
Preferred Enterprise unless the Preferred Enterprise is located in development zone A, in which case the rate will be 9%. This latter rate was reduced to
7.5% as of January 1, 2017. It should be noted that the classification of income generated from the provision of usage rights in know-how or software that
were developed in the Preferred Enterprise, as well as royalty income received with respect to such usage, as Preferred Enterprise income may be subject to
the issuance of a pre-ruling from the Israel Tax Authority stipulating that such income is associated with the productive activity of the Preferred Enterprise
in Israel.

Dividends paid out of income attributed to a Preferred Enterprise are generally subject to withholding tax at source at the rate of 20% or such lower rate as
may be provided in an applicable tax treaty. However, if such dividends are paid to an Israeli company, no tax is required to be withheld (although, if such
dividends are subsequently distributed to individuals or a non-Israeli company, withholding tax at a rate of 20% or such lower rate as may be provided in an
applicable tax treaty will apply).

The 2011 Amendment also provided transitional provisions to address companies that may be eligible for tax benefits under the Approved Enterprise or
Benefited Enterprise regimes. These transitional provisions provide, among other things, that unless an irrevocable request is made to apply the provisions
of the Investment Law as amended in 2011 with respect to income to be derived as of January 1, 2011: (1) the terms and benefits included in any certificate
of approval that was granted to an Approved Enterprise which chose to receive grants before the 2011 Amendment became effective will remain subject to
the provisions of the Investment Law as in effect on the date of such approval, and subject to certain other conditions, (2) terms and benefits included in
any certificate of approval that was granted to an Approved Enterprise which had participated in an alternative benefits track before the 2011 Amendment
became effective will remain subject to the provisions of the Investment Law as in effect on the date of such approval, provided that certain conditions are
met, and (3) a Benefited Enterprise can elect to continue to benefit from the benefits provided to it before the 2011 Amendment came into effect, provided
that certain conditions are met.

We have examined the potential Israeli tax implications associated with the adoption and implementation of the provisions of the 2011 Amendment and
have decided, at this time, not to apply the new benefits under the 2011 Amendment. There is no assurance that our future taxable income will qualify as
Preferred Enterprise income or that the benefits described above will be available to us in the future.

The termination or substantial reduction of any of the benefits available under the Investment Law could materially increase our tax liabilities.

Tax Benefits Under the 2017 Amendment

The  2017  Amendment  introduced  new  benefits  for  income  generated  by  a  “Preferred  Company”  (as  defined  above)  through  its  “Preferred  Technology
Enterprise” (as defined in the Investment Law) as of January 1, 2017. Pursuant to the 2017 Amendment, in 2017 and thereafter a Preferred Company is
entitled to a reduced corporate tax rate of 12% with respect to its income derived by its Preferred Technology Enterprise unless the Preferred Enterprise is
located in development zone A, in which case the rate will be 7.5%. It should be noted that the calculation of a Preferred Company’s Preferred Technology
Enterprise  income  is  based  on  a  complex  formula  and  the  income  not  classified  as  such  may  be  classified  as  Preferred  Enterprise  income  or  ordinary
income depending on the circumstances. In addition, a Preferred Company must generally fulfill certain conditions to be eligible for Preferred Technology
Enterprise status including, inter alia , an R&D expenses level of at least 7% of total revenues or NIS 75 million per year.

Dividends paid out of Preferred Technology Enterprise income are generally subject to withholding tax at source at the rate of 20% or such lower rate as
may be provided in an applicable tax treaty. However, subject to the fulfillment of certain conditions, to the extent that the dividends are paid to a direct
foreign parent company holding at least 90% of the shares of the Preferred Company, a reduced withholding tax rate of 4% shall apply. Notwithstanding the
above,  if  such  dividends  are  paid  to  an  Israeli  company,  no  tax  is  required  to  be  withheld  (although,  if  such  dividends  are  subsequently  distributed  to
individuals or a non-Israeli company, withholding tax at a rate of 20% or such lower rate as may be provided in an applicable tax treaty will apply).

Preferred Technology Enterprise income or that the benefits described above will be available to us in the future.

The termination or substantial reduction of any of the benefits available under the Investment Law could materially increase our tax liabilities.

Taxation of Our Shareholders

This discussion does not address the tax consequences applicable to shareholders that own, or have owned at any time, directly or indirectly, 10% or more
of our shares (“Controlling Shareholders”), and such shareholders should consult their tax advisers as to the tax consequences of owning or disposing of
our shares.

Capital Gains Taxes Applicable to Non-Israeli Resident Shareholders

A non-Israeli resident who derives capital gains from the sale of shares in an Israeli resident company that were purchased after the Company was listed for
trading on a stock exchange outside of Israel will be exempt from Israeli tax so long as, inter alia , such capital gains were not attributable to a permanent
establishment that the non-resident maintains in Israel.

However, non-Israeli resident corporations will not be entitled to the foregoing exemption if the Israeli residents: (i) have a controlling interest, directly or
indirectly,  alone,  together  with  another  (i.e.,  together  with  a  relative,  or  together  with  someone  who  is  not  a  relative  but  with  whom,  according  to  an
agreement, there is regular cooperation in material matters of the company, directly or indirectly), or together with another Israeli resident, of more than
25% in one or more of the means of control in such non-Israeli resident corporation, or (ii) Israeli residents are the beneficiaries of, or are entitled to, 25%
or more of the revenues or profits of such non-Israeli resident corporation, whether directly or indirectly.

Additionally, a sale of securities by a non-Israeli resident may be exempt from Israeli capital gains tax under the provisions of an applicable tax treaty. For
example, under the United States- Israel Tax Treaty, the disposition of shares by a shareholder who (1) is a U.S. resident (for purposes of the treaty), (2)
holds the shares as a capital asset, and (3) is entitled to claim the benefits afforded to such person by the treaty, is generally exempt from Israeli capital
gains tax. Such exemption will not apply if: (1) the capital gain arising from the disposition can be attributed to a permanent establishment in Israel, (2) the
shareholder  holds,  directly  or  indirectly,  shares  representing  10%  or  more  of  the  voting  power  of  the  company  during  any  part  of  the  12-month  period
preceding the disposition, subject to certain conditions, or (3) such U.S. resident is an individual and was present in Israel for 183 days or more during the
relevant  taxable  year.  In  such  case,  the  sale,  exchange  or  disposition  of  our  ordinary  shares  would  be  subject  to  Israeli  tax,  to  the  extent  applicable;
however, under the United States-Israel Tax Treaty, the taxpayer would be permitted to claim a credit for such taxes against the U.S. federal income tax
imposed with respect to such sale, exchange or disposition, subject to the limitations under U.S. law applicable to foreign tax credits. The United States-
Israel Tax Treaty does not relate to U.S. state or local taxes.

In some instances where our shareholders may be liable for Israeli tax on the sale of their ordinary shares, the payment of the consideration may be subject
to the withholding of Israeli tax at source. Shareholders may be required to demonstrate that they are exempt from tax on their capital gains in order to
avoid withholding at source at the time of sale.

Taxation of Non-Israeli Shareholders on Receipt of Dividends

Non-Israeli residents are generally subject to Israeli withholding tax on the receipt of dividends paid on our ordinary shares at the rate of 25%, unless relief
is  provided  in  a  treaty  between  Israel  and  the  shareholder’s  country  of  residence,  subject  to  receipt  of  a  valid  certificate  from  the  Israeli  Tax  Authority
allowing for such reduced rate. With respect to a person who is a “substantial shareholder” at the time of receiving the dividend or at any time during the
preceding twelve months, the applicable withholding tax rate is 30%. Furthermore, an additional 3% tax might be applicable to individual shareholders if
certain  conditions  are  met. A  “substantial  shareholder”  is  generally  a  person  who  alone  or  together  with  such  person’s  relative  or  another  person  who
collaborates with such person on a permanent basis, holds, directly or indirectly, at least 10% of any of the “means of control” of the corporation. “Means
of control” generally include the right to vote, receive profits, nominate a director or an executive officer, receive assets upon liquidation, or order someone
who holds any of the aforesaid rights how to act, regardless of the source of such right. Notwithstanding the above, dividends paid to a non-Israeli resident
“substantial  shareholder”  on  publicly  traded  shares,  like  our  ordinary  shares,  which  are  held  via  a  “nominee  company”  (as  defined  under  the  Securities
Law, 1968), are generally subject to Israeli withholding tax at a rate of 25%, unless a different rate is provided under an applicable tax treaty, provided that
a certificate from the Israeli Tax Authority allowing for a reduced withholding tax rate is obtained in advance. Under the United States-Israel Tax Treaty,
the maximum rate of tax withheld at source in Israel on dividends paid to a holder of our ordinary shares who is a U.S. resident (for purposes of the United
States- Israel Tax Treaty) is 25%. Unless a reduced tax rate is provided under an applicable tax treaty, a distribution of dividends to non-Israeli residents is
subject  to  withholding  tax  at  source  at  a  rate  of  15%  if  the  dividend  is  distributed  from  income  attributed  to  an  Approved  Enterprise  or  a  Benefited
Enterprise, while a 20% rate applies if the dividend is distributed from Preferred Enterprise income or Preferred Technology Enterprise income (unless the
dividend is paid to a foreign parent company directly holding at least 90% of the shares of the Preferred Company, in which case a 4% withholding tax rate
shall apply). We cannot assure you that in the event we declare a dividend we will designate the income out of which the dividend is paid in a manner that
will reduce shareholders’ tax liability.

If the dividend is attributable partly to Approved Enterprise income, Benefited Enterprise income, Preferred Enterprise income or Preferred Technology
Enterprise income, and partly to other sources of income, the withholding rate will be a blended rate reflecting the relative portions of the two types of
income. U.S. residents who are subject to Israeli withholding tax on a dividend may be entitled to a credit or deduction for Untied States federal income tax
purposes in the amount of the taxes withheld, subject to detailed rules contained in U.S. tax legislation.

Estate and Gift Tax

Israeli law presently does not impose estate or gift taxes.

Certain Material U.S. Federal Income Tax Considerations

The following is a description of the material U.S. federal income tax considerations relating to the ownership and disposition of our ordinary shares by a
U.S. Holder (as defined below). This description addresses only the U.S. federal income tax considerations to U.S. Holders that will hold such ordinary
shares as capital assets. This description does not address tax considerations applicable to U.S. Holders that may be subject to special tax rules, including,
without limitation:

●

●

●

●

●

●

●

●

●

●

●

●

banks, financial institutions or insurance companies;

real estate investment trusts, regulated investment companies or grantor trusts;

brokers, dealers or traders in securities, commodities or currencies;

tax exempt entities or organizations, including an “individual retirement account” or “Roth IRA” as defined in Section 408 or 408A of the Code (as
defined below), respectively;

certain former citizens or long term residents of the United States;

persons that received our shares as compensation for the performance of services;

persons that will hold our shares as part of a “hedging,” “integrated” or “conversion” transaction or as a position in a “straddle” for U.S. federal
income tax purposes;

partnerships (including entities classified as partnerships for U.S. federal income tax purposes) or other pass-through entities, or holders that will
hold our shares through such an entity;

S corporations;

persons that acquire ordinary shares as a result of holding or owning our preferred shares;

persons whose “functional currency” is not the U.S. dollar; or

persons that own directly, indirectly or through attribution 10% or more of the voting power or value of our shares.

Moreover, this description does not address the U.S. federal estate, gift, or alternative minimum tax considerations, or any U.S. state, local or non-U.S. tax
considerations of the ownership and disposition of our ordinary shares.

This  description  is  based  on  the  U.S.  Internal  Revenue  Code  of  1986,  as  amended,  or  the  Code,  changes  to  the  code  based  on  the  U.S.  tax  reform  (as
described  below)  existing,  proposed  and  temporary  U.S.  Treasury  Regulations  promulgated  thereunder  and  administrative  and  judicial  interpretations
thereof, in each case as in effect and available on the date hereof. All the foregoing is subject to change, which change could apply retroactively, and to
differing  interpretations,  all  of  which  could  affect  the  tax  considerations  described  below.  There  can  be  no  assurances  that  the  U.S.  Internal  Revenue
Service, or the IRS, will not take a different position concerning the tax consequences of the ownership and disposition of our ordinary shares or that such a
position would not be sustained. Holders should consult their own tax advisers concerning the U.S. federal, state, local and foreign tax consequences of
owning and disposing of our ordinary shares in their particular circumstances.

For purposes of this description, the term “U.S. Holder” means a beneficial owner of our ordinary shares that, for U.S. federal income tax purposes, is (i) a
citizen or resident of the United States, (ii) a corporation (or entity treated as a corporation for U.S. federal income tax purposes) created or organized in or
under the laws of the United States, any state thereof, or the District of Columbia, (iii) an estate the income of which is subject to U.S. federal income tax
regardless of its source, or (iv) a trust with respect to which a court within the United States is able to exercise primary supervision over its administration
and one or more U.S. persons have the authority to control all of its substantial decisions.

If a partnership (or any other entity treated as a partnership for U.S. federal income tax purposes) holds our ordinary shares, the U.S. federal income tax
consequences relating to an investment in our ordinary shares will depend in part upon the status of the partner and the activities of the partnership. Such a
partner  or  partnership  should  consult  its  tax  advisor  regarding  the  U.S.  federal  income  tax  considerations  of  acquiring,  owning  and  disposing  of  our
ordinary shares in its particular circumstances.

As indicated below, this discussion is subject to U.S. federal income tax rules applicable to a “passive foreign investment company,” or a PFIC.

Persons considering an investment in our ordinary shares should consult their own tax advisors as to the particular tax consequences applicable to
them relating to the ownership and disposition of our ordinary shares, including the applicability of U.S. federal, state and local tax laws and non-
U.S. tax laws.

Distributions

Subject  to  the  discussion  under  “-Passive  Foreign  Investment  Company  Considerations,”  below,  if  you  are  a  U.S.  Holder,  the  gross  amount  of  any
distribution made to you with respect to our ordinary shares before reduction for any Israeli taxes withheld therefrom, other than certain distributions, if
any, of our ordinary shares distributed pro rata to all our shareholders, generally will be includible in your income as dividend income to the extent such
distribution is paid out of our current or accumulated earnings and profits as determined under U.S. federal income tax principles. To the extent that the
amount of any distribution by us exceeds our current and accumulated earnings and profits as determined under U.S. federal income tax principles, it will
generally be treated first as a return of your adjusted tax basis in our ordinary shares and thereafter as either long-term or short-term capital gain depending
upon whether the U.S. Holder has held our ordinary shares for more than one year as of the time such distribution is received. We do not expect to maintain
calculations  of  our  earnings  and  profits  under  U.S.  federal  income  tax  principles.  Therefore,  U.S.  Holders  should  expect  that  the  entire  amount  of  any
distribution generally will be reported as dividend income. Non-corporate U.S. Holders may qualify for the preferential rates of taxation with respect to
dividends  on  ordinary  shares  applicable  to  long-term  capital  gains  (i.e.,  gains  from  the  sale  of  capital  assets  held  for  more  than  one  year)  applicable  to
qualified dividend income (as discussed below). The Company, which is incorporated under the laws of the State of Israel, believes that it qualifies as a
resident  of  Israel  for  purposes  of,  and  is  eligible  for  the  benefits  of,  the  Convention  between  the  Government  of  the  United  States  of  America  and  the
Government of the State of Israel with Respect to Taxes on Income, signed on November 20, 1975, as amended and currently in force, or the U.S.-Israel
Tax Treaty, although there can be no assurance in this regard. Further, the IRS has determined that the U.S.-Israel Tax Treaty is satisfactory for purposes of
the  qualified  dividend  rules  and  that  it  includes  an  exchange-of-information  program.  Therefore,  subject  to  the  discussion  under  “-Passive  Foreign
Investment Company Considerations,” below, if the U.S.-Israel Tax Treaty is applicable, such dividends will generally be “qualified dividend income” in
the  hands  of  individual  U.S.  Holders,  provided  that  certain  conditions  are  met,  including  holding  period  and  the  absence  of  certain  risk  reduction
transaction requirements are met. The dividends will not be eligible for the dividends received deduction generally allowed to corporate U.S. Holders.

On December 22, 2017, President Trump signed into law the Tax Cuts and Jobs Act, or the TCJA. The TCJA provides a 100% deduction for the foreign-
source portion of dividends received after January 1, 2018 from “specified 10-percent owned foreign corporations” by U.S. corporate holders, subject to a
one-year holding period. No foreign tax credit, including Israeli withholding tax (or deduction for foreign taxes paid with respect to qualifying dividends)
would be permitted for foreign taxes paid or accrued with respect to a qualifying dividend. Deduction would be unavailable for “hybrid dividends.” The
dividend received deduction enacted under the TCJA may not apply to dividends from a passive foreign investment company.

U.S. Holders, other than certain U.S. Holder’s that are U.S. corporations, generally may claim the amount of Israeli withholding tax withheld either as a
deduction  from  gross  income  or  as  a  credit  against  U.S.  federal  income  tax  liability.  However,  the  foreign  tax  credit  is  subject  to  numerous  complex
limitations that must be determined and applied on an individual basis. Generally, the credit cannot exceed the proportionate share of a U.S. Holder’s U.S.
federal income tax liability that such U.S. Holder’s “foreign source” taxable income bears to such U.S. Holder’s worldwide taxable income. In applying
this limitation, a U.S. Holder’s various items of income and deduction must be classified, under complex rules, as either “foreign source” or “U.S. source.”
In addition, this limitation is calculated separately with respect to specific categories of income. The amount of a distribution with respect to the ordinary
shares that is treated as a “dividend” may be lower for U.S. federal income tax purposes than it is for Israeli income tax purposes, potentially resulting in a
reduced foreign tax credit for the U.S. Holder. Each U.S. Holder should consult its own tax advisors regarding the foreign tax credit rules.

In general, the amount of a distribution paid to a U.S. Holder in a foreign currency will be the dollar value of the foreign currency calculated by reference
to the spot exchange rate on the day the U.S. Holder receives the distribution, regardless of whether the foreign currency is converted into U.S. dollars at
that time. Any foreign currency gain or loss a U.S. Holder realizes on a subsequent conversion of foreign currency into U.S. dollars will be U.S. source
ordinary income or loss. If dividends received in foreign currency are converted into U.S. dollars on the day they are received, a U.S. Holder generally
should not be required to recognize foreign currency gain or loss in respect of the dividend.

Table of Contents

Sale, Exchange or Other Taxable Disposition of Our Ordinary Shares

Subject to the discussion below under “-Passive Foreign Investment Company Considerations,” if you are a U.S. Holder, you generally will recognize gain
or loss on the sale, exchange or other taxable disposition of our ordinary shares equal to the difference between the amount realized on such sale, exchange
or other taxable disposition and your adjusted tax basis in our ordinary shares, and such gain or loss will be capital gain or loss. The adjusted tax basis in an
ordinary share generally will be equal to the cost of such ordinary share. If you are a non-corporate U.S. Holder, capital gain from the sale, exchange or
other  taxable  disposition  of  ordinary  shares  is  generally  eligible  for  a  preferential  rate  of  taxation  applicable  to  capital  gains,  if  your  holding  period
determined at the time of such sale, exchange or other taxable disposition for such ordinary shares exceeds one year (i.e., such gain is long-term capital
gain). The deductibility of capital losses for U.S. federal income tax purposes is subject to limitations under the Code. Any such gain or loss that a U.S.
Holder recognizes generally will be treated as U.S. source income or loss for foreign tax credit limitation purposes.

For a cash basis taxpayer, units of foreign currency paid or received are translated into U.S. dollars at the spot rate on the settlement date of the purchase or
sale. In that case, no foreign currency exchange gain or loss will result from currency fluctuations between the trade date and the settlement date of such a
purchase or sale. An accrual basis taxpayer, however, may elect the same treatment required of cash basis taxpayers with respect to purchases and sales of
our ordinary shares that are traded on an established securities market, provided the election is applied consistently from year to year. Such election may
not be changed without the consent of the IRS. For an accrual basis taxpayer who does not make such election, units of foreign currency paid or received
are translated into U.S. dollars at the spot rate on the trade date of the purchase or sale. Such an accrual basis taxpayer may recognize exchange gain or loss
based on currency fluctuations between the trade date and the settlement date. Any foreign currency gain or loss a U.S. Holder realizes will be U.S. source
ordinary income or loss.

Passive Foreign Investment Company Considerations

If we are classified as a PFIC in any taxable year, a U.S. Holder would be subject to special rules generally intended to reduce or eliminate any benefits
from  the  deferral  of  U.S.  federal  income  tax  that  a  U.S.  Holder  could  derive  from  investing  in  a  non-U.S.  company  that  does  not  distribute  all  of  its
earnings on a current basis.

A non-U.S. corporation is classified as a PFIC for U.S. federal income tax purposes in any taxable year in which, after applying certain look-through rules
with respect to the income and assets of subsidiaries, either (i) at least 75% of its gross income is “passive income” or (ii) at least 50% of the average
quarterly value of its total gross assets (which, assuming we are not a CFC for the year being tested, would be measured by fair market value of the assets,
and for which purpose the total value of our assets may be determined in part by the market value of our ordinary shares, which is subject to change) is
attributable to assets that produce “passive income” or are held for the production of passive income.

Passive income for this purpose generally includes dividends, interest, royalties, rents, gains from commodities and securities transactions, the excess of
gains over losses from the disposition of assets which produce passive income, and includes amounts derived by reason of the temporary investment of
funds  raised  in  offerings  of  our  ordinary  shares.  If  a  non-U.S.  corporation  owns  directly  or  indirectly  at  least  25%  by  value  of  the  stock  of  another
corporation, the non-U.S. corporation is treated for purposes of the PFIC tests as owning its proportionate share of the assets of the other corporation and as
receiving directly its proportionate share of the other corporation’s income. If we are classified as a PFIC in any year with respect to which a U.S. Holder
owns our ordinary shares, we will continue to be treated as a PFIC with respect to such U.S. Holder in all succeeding years during which the U.S. Holder
owns our ordinary shares, regardless of whether we continue to meet the tests described above.

We must determine our PFIC status annually based on tests which are factual in nature, and our status will depend on our income, assets and activities each
year.

We  believe  that  we  were  not  a  PFIC  for  our  2020  taxable  year.  However,  we  expect  that  unless  and  until  we  generate  sufficient  revenue  from  active
licensing and other non-passive sources and otherwise satisfy the asset test above, we will be treated as a PFIC in future taxable years.

If we are a PFIC, and you are a U.S. Holder, then unless you make one of the elections described below, a special tax regime will apply to both (a) any
“excess  distribution”  by  us  to  you  (generally,  your  ratable  portion  of  distributions  in  any  year  which  are  greater  than  125%  of  the  average  annual
distribution received by you in the shorter of the three preceding years or your holding period for our ordinary shares) and (b) any gain realized on the sale
or  other  disposition  of  the  ordinary  shares.  Under  this  regime,  any  excess  distribution  and  realized  gain  will  be  treated  as  ordinary  income  and  will  be
subject to tax as if (a) the excess distribution or gain had been realized ratably over your holding period, (b) the amount deemed realized in each year had
been subject to tax in each year of that holding period at the highest marginal rate for such year (other than income allocated to the current period or any
taxable period before we became a PFIC, which would be subject to tax at the U.S. Holder’s regular ordinary income rate for the current year and would
not be subject to the interest charge discussed below), and (c) the interest charge generally applicable to underpayments of tax had been imposed on the
taxes deemed to have been payable in those years. In addition, dividend distributions made to you will not qualify for the lower rates of taxation applicable
to long-term capital gains discussed above under “Distributions.”

Table of Contents

Certain elections may potentially be used to reduce the adverse impact of the PFIC rules on U.S. Holders (“qualifying electing fund” (“QEF”) and “mark-
to-market” elections), but these elections may accelerate the recognition of taxable income and may result in the recognition of ordinary income.

The rules described above for excess distributions would not apply to a U.S. Holder if the U.S. Holder makes a timely QEF election for the first taxable
year of the U.S. Holder’s holding period for ordinary shares and we comply with specified reporting requirements. A timely QEF election for a taxable year
generally must be made on or before the due date (as may be extended) for filing the taxpayer’s U.S. federal income tax return for the year. A U.S. Holder
who makes a QEF election generally must report on a current basis a pro rata share of our ordinary earnings and net capital gain for any taxable year in
which we are a PFIC, whether or not those earnings or gains are distributed. A U.S. Holder who makes a QEF election must file a Form 8621 with its
annual income tax return. We have not historically provided the information necessary for U.S. Holders to make qualified electing fund elections. However,
beginning with our 2016 taxable year, for U.S. Holders who seek to make a QEF election with respect to our ordinary shares, we intend to make available
an information statement that will contain the necessary information required for making a QEF election and permit such U.S. Holders access to certain
information in the event of an audit by the U.S. tax authorities.

If a U.S. Holder does not make a QEF election for the first taxable year of the U.S. Holder’s holding period for ordinary shares during which we are a
PFIC, the QEF election will not be treated as timely and the adverse tax regime described above would apply to dispositions of or excess distributions on
the ordinary shares. In such case, a U.S. Holder may make a deemed sale election whereby the U.S. Holder would be treated as if the U.S. Holder had sold
the ordinary shares in a fully taxable sale at fair market value on the first day of such taxable year in which the QEF election takes effect. Such U.S. Holder
would be required to recognize any gain on the deemed sale as an excess distribution and pay any tax and interest due on the excess distribution when
making the deemed sale election. The effect of such further election would be to restart the U.S. Holder’s holding period in the ordinary shares, subject to
the QEF regime, and to purge the PFIC status of such ordinary shares going forward.

If a U.S. Holder makes the mark-to-market election, the U.S. Holder generally will recognize as ordinary income any excess of the fair market value of the
ordinary shares at the end of each taxable year over their adjusted tax basis, and will recognize an ordinary loss in respect of any excess of the adjusted tax
basis  of  the  ordinary  shares  over  their  fair  market  value  at  the  end  of  the  taxable  year  (but  only  to  the  extent  of  the  net  amount  of  income  previously
included as a result of the mark-to-market election). If a U.S. Holder makes the election, the U.S. Holder’s tax basis in the ordinary shares will be adjusted
to  reflect  these  income  or  loss  amounts.  Any  gain  recognized  on  the  sale  or  other  disposition  of  ordinary  shares  in  a  year  when  we  are  a  PFIC  will  be
treated as ordinary income and any loss will be treated as an ordinary loss (but only to the extent of the net amount of income previously included as a
result of the mark-to-market election). The mark-to-market election is available only if we are a PFIC and our ordinary shares are “regularly traded” on a
“qualified  exchange.”  Our  ordinary  shares  will  be  treated  as  “regularly  traded”  in  any  calendar  year  in  which  more  than  a  de  minimis  quantity  of  the
ordinary shares are traded on a qualified exchange on at least 15 days during each calendar quarter (subject to the rule that trades that have as one of their
principle  purposes  the  meeting  of  the  trading  requirement  as  disregarded).  The  NASDAQ  Global  Market  is  a  qualified  exchange  for  this  purpose  and,
consequently, if the ordinary shares are regularly traded, the mark-to-market election will be available to a U.S. Holder.

U.S.  Holders  should  consult  their  tax  advisors  to  determine  whether  any  of  these  elections  would  be  available  and  if  so,  what  the  consequences  of  the
alternative treatments would be in their particular circumstances.

If we are a PFIC, the general tax treatment for U.S. Holders described in this section would apply to indirect distributions and gains deemed to be realized
by U.S. Holders in respect of any of our subsidiaries that also may be determined to be PFICs.

If a U.S. Holder owns ordinary shares during any year in which we are a PFIC and the U.S. Holder recognizes gain on a disposition of our ordinary shares
or receives distributions with respect to our ordinary shares, the U.S. Holder generally will be required to file an IRS Form 8621 (Information Return by a
Shareholder of a Passive Foreign Investment Company or Qualified Electing Fund) with respect to the company, generally with the U.S. Holder’s federal
income tax return for that year. If our company were a PFIC for a given taxable year, then you should consult your tax advisor concerning your annual
filing requirements.

The  U.S.  federal  income  tax  rules  relating  to  PFICs  are  complex.  Prospective  U.S.  investors  are  urged  to  consult  their  own  tax  advisers  with
respect to the ownership and disposition of our ordinary shares, the consequences to them of an investment in a PFIC, any elections available with
respect to our ordinary shares and the IRS information reporting obligations with respect to the ownership and disposition of our ordinary shares.

Medicare Tax

Certain  U.S.  Holders  that  are  individuals,  estates  or  trusts  may  be  required  to  pay  an  additional  3.8%  Medicare  tax  on  all  or  a  portion  of  their  “net
investment income,” which may include all or a portion of their dividend income and net gains from the disposition of ordinary shares. U.S. Holders will
likely not be able to credit foreign taxes against the 3.8% Medicare tax. Each U.S. Holder that is an individual, estate or trust is urged to consult its tax
advisors regarding the applicability of the Medicare tax to its income and gains in respect of its investment in our ordinary shares.

Backup Withholding Tax and Information Reporting Requirements

U.S.  backup  withholding  tax  and  information  reporting  requirements  may  apply  to  certain  payments  to  certain  shareholders.  Information  reporting
generally will apply to payments of dividends on, and to proceeds from the sale or redemption of, our ordinary shares made within the United States, or by
a U.S. payor or U.S. middleman, to a holder of our ordinary shares, other than an exempt recipient (including a payee that is not a U.S. person that provides
an appropriate certification and certain other persons). A payor may be required to withhold backup withholding tax from any payments of dividends on, or
the proceeds from the sale or redemption of, ordinary shares within the United States, or by a U.S. payor or U.S. middleman, to a holder, other than an
exempt recipient, if such holder fails to furnish its correct taxpayer identification number or otherwise fails to comply with, or establish an exemption from,
such backup withholding tax requirements. Any amounts withheld under the backup withholding rules should generally be allowed as a credit against the
beneficial  owner’s  U.S.  federal  income  tax  liability,  if  any,  and  any  excess  amounts  withheld  under  the  backup  withholding  rules  may  be  refunded,
provided that the required information is timely furnished to the IRS.

Foreign Asset Reporting

Certain U.S. Holders who are individuals may be required to report information relating to an interest in our ordinary shares, subject to certain exceptions
(including an exception for shares held in accounts maintained by U.S. financial institutions) by filing IRS Form 8938 (Statement of Specified Foreign
Financial Assets) with their federal income tax return. U.S. Holders are urged to consult their tax advisors regarding their information reporting obligations,
if any, with respect to their ownership and disposition of our ordinary shares.

Foreign Account Tax Compliance Act

The  Foreign  Account  Tax  Compliance  Act  (“FATCA”)  encourages  foreign  financial  institutions  to  report  information  about  their  U.S.  account  holders
(including holders of certain equity interests) to the IRS. Foreign financial institutions that fail to comply with the withholding and reporting requirements
of FATCA and certain account holders that do not provide sufficient information under the requirements of FATCA are subject to a 30% U.S. withholding
tax on certain payments they receive, including foreign passthru payments (which may include payments made by us with respect to our ordinary shares).
The term “foreign passthru payment” is not currently defined in U.S. Treasury Regulations, and therefore, the future application of FATCA withholding tax
on foreign pass-thru payments to holders of ordinary shares is uncertain. If a holder of ordinary shares is subject to withholding, there will be no additional
amounts payable by way of compensation to the holder of such securities for the deducted amount. Holders of ordinary shares should consult their own tax
advisors regarding this legislation in light of such holder’s particular situation.

THE DISCUSSION ABOVE IS A GENERAL SUMMARY. IT DOES NOT COVER ALL TAX MATTERS THAT MAY BE OF IMPORTANCE TO A
PROSPECTIVE  INVESTOR.  EACH  PROSPECTIVE  INVESTOR  IS  URGED  TO  CONSULT  ITS  OWN  TAX  ADVISOR  ABOUT  THE  TAX
CONSEQUENCES TO IT OF AN INVESTMENT IN ORDINARY SHARES IN LIGHT OF THE INVESTOR’S OWN CIRCUMSTANCES.

Item 11. Quantitative and Qualitative Disclosures About Market Risk

We are exposed to market risks in the ordinary course of our business. Market risk represents the risk of loss that may impact our financial position due to
adverse changes in financial market prices and rates. Our market risk exposure is primarily a result of foreign currency exchange rates. Approximately 33%
of our expenses in 2020 were denominated in New Israeli Shekels. Changes of 5% in the US$/NIS exchange rate will increase or decrease the operating
expenses by up to 1%.

Foreign Currency Risk

Fluctuations in exchange rates, especially the NIS against the U.S. dollar, may affect our results, as some of our assets are linked to NIS, as are some of our
liabilities. In addition, the fluctuation in the NIS exchange rate against the U.S. dollar may impact our results, as a portion of our operating costs are NIS
denominated.

The following table presents information about the changes in the exchange rates of the NIS against the U.S. dollar at year end:

Period

Year ended December 31, 2019

Inflation Risk

%

(6.97)%
(7.79)%

We do not believe that inflation had a material effect on our business, financial condition or results of operations in the last three fiscal years. If our costs
were to become subject to significant inflationary pressures, we may not be able to fully offset such higher costs through hedging transactions. Our inability
or failure to do so could harm our business, financial condition and results of operations.

Disclosure Controls and Procedures

We have performed an evaluation of the effectiveness of our disclosure controls and procedures that are designed to ensure that the material financial and
non-financial  information  required  to  be  disclosed  to  the  SEC  is  recorded,  processed,  summarized  and  reported  timely.  Based  on  our  evaluation,  our
management,  including  the  Chief  Executive  Officer,  or  CEO  and  the  Chief  Financial  Officer,  or  CFO,  has  concluded  that  our  disclosure  controls  and
procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934, as amended) as of the end of the period covered by this
report are effective. Notwithstanding the foregoing, there can be no assurance that our disclosure controls and procedures will detect or uncover all failures
of persons within the Company to disclose material information otherwise required to be set forth in our reports.

Management’s Annual Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Rule 13a-
15(f) promulgated under the Exchange Act. Our internal control system was designed to provide reasonable assurance to our management and board of
directors regarding the reliability of financial reporting and the preparation and fair presentation of published financial statements for external purposes in
accordance with generally accepted accounting principles. All internal control systems, no matter how well designed, have inherent limitations. Therefore,
even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation and
may  not  prevent  or  detect  misstatements.  Also,  projections  of  any  evaluation  of  effectiveness  to  future  periods  are  subject  to  the  risk  that  controls  may
become inadequate because of changes in conditions, or that the degree of compliance with policies or procedures may deteriorate.

Our  management,  including  our  CEO  and  CFO,  conducted  an  evaluation,  pursuant  to  Rule  13a-15(c)  promulgated  under  the  Exchange  Act,  of  the
effectiveness, as of the end of the period covered by this Annual Report, of the Company’s internal control over financial reporting based on the framework
in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013). Based on the results
of this evaluation, management concluded that our internal control over financial reporting was effective as of December 31, 2020.

This annual report does not include an attestation report of the Company’s registered public accounting firm because management’s report was not subject
to attestation by our independent registered public accounting firm because, as a non-accelerated filer, we are exempt from this requirement.

Item 16F. Change in Registrant’s Certifying Accountant

None.

Item 16G. Corporate Governance

As  a  foreign  private  issuer  whose  shares  are  listed  on  the  NASDAQ  Global  Market,  we  have  the  option  to  follow  certain  Israeli  corporate  governance
practices rather than those of NASDAQ, except to the extent that such laws would be contrary to U.S. securities laws and provided that we disclose the
practices we are not following and describe the home country practices we follow instead. We rely on this “foreign private issuer exemption” with respect
to the following NASDAQ requirements:

●

Quorum requirement. Under our articles of association and as permitted under the Companies Law, a quorum for any meeting of shareholders shall
be the presence of at least two shareholders present in person, by proxy or by a voting instrument, who hold at least 25% of the voting power of our
shares instead of 33 1 3 % of the issued share capital required under Nasdaq requirements.

Except  as  stated  above,  we  comply  with  the  rules  generally  applicable  to  U.S.  domestic  companies  listed  on  NASDAQ.  We  may  in  the  future  elect  to
follow  home  country  practices  in  Israel  with  regard  to  other  matters,  including  the  formation  of  compensation,  nominating  and  corporate  governance
committees, separate executive sessions of independent directors and non-management directors and the requirement to obtain shareholder approval for
certain dilutive events (such as for the establishment or amendment of certain equity-based compensation plans, issuances that will result in a change of
control  of  the  company,  certain  transactions  other  than  a  public  offering  involving  issuances  of  a  20%  or  more  interest  in  the  company  and  certain
acquisitions of the stock or assets of another company).

Following  our  home  country  governance  practices,  as  opposed  to  the  requirements  that  would  otherwise  apply  to  a  company  listed  on  NASDAQ,  may
provide less protection than is accorded to investors under NASDAQ listing requirements applicable to domestic issuers. For more information, see “Item
3. Risk Factors- We are a “foreign private issuer” and intend to follow certain home country corporate governance practices, and our shareholders may not
have  the  same  protections  afforded  to  shareholders  of  companies  that  are  subject  to  all  NASDAQ  corporate  governance  requirements.  Additionally,  we
cannot be certain if the reduced disclosure requirements applicable to our status as a foreign private issuer, will make our ordinary shares less attractive to
investors.”  We  will  also  be  required  to  comply  with  Israeli  corporate  governance  requirements  under  the  Companies  Law  applicable  to  Israeli  public
companies such as us whose shares are also listed for trade on an exchange outside Israel.

Report of Independent Registered Public Accounting Firm

To the board of directors and shareholders of Vascular Biogenics Ltd.

Opinion on the Financial Statements

We have audited the accompanying statements of financial position of Vascular Biogenics Ltd. (the “Company”) as of December 31, 2020 and 2019, and
the related statements of net loss and comprehensive loss, changes in shareholders’ equity and cash flows for each of the three years in the period ended
December  31,  2020,  including  the  related  notes  (collectively  referred  to  as  the  “financial  statements”).  In  our  opinion,  the  financial  statements  present
fairly, in all material respects, the financial position of the Company as of December 31, 2020 and 2019 , and the results of its operations and its cash flows
for each of the three years in the period ended December 31, 2020 in conformity with accounting principles generally accepted in the United States of
America.

Change in Accounting Principle

As discussed in Note 2(p) to the financial statements, the Company changed the manner in which it accounts for leases in 2019.

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 U.S. federal securities laws and the applicable rules and
regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits of these financial statements 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.

Critical Audit Matters

Critical audit matters are matters arising from the current period audit of the financial statements that were communicated or required to be communicated
to the audit committee and that (i) relate to accounts or disclosures that are material to the financial statements and (ii) involved our especially challenging,
subjective, or complex judgments. We determined there are no critical audit matters.

VASCULAR BIOGENICS LTD.
NOTES TO THE FINANCIAL STATEMENTS

NOTE 1 – SIGNIFICANT ACCOUNTING POLICIES:

  a.    General

Vascular Biogenics Ltd. (the “Company” or VBL) was incorporated on January 27, 2000. The Company is a late-stage clinical biopharmaceutical
company focused on the discovery, development and commercialization of first-inclass treatments for cancer and immune/inflammatory indications.
VB-111 (ofranergene obadenovec), a Phase 3 drug candidate, is the lead product candidate in the Company’s cancer program.

VB-600  series  are  preclinical  stage  antibodies  targeting  MOSPD2  for  inflammatory  and  oncology  indications,  which  are  being  advanced  towards
IND VB-601 is the lead mAb candidate for various inflammatory indications and VB-611 is the lead bi-specific mAb for various solid tumors.

VB-201, a Phase 2-ready drug candidate, is the Company’s lead Lecinoxoid-based product candidate for chronic immune-related indications.

The  Company  is  engaged  in  an  exclusive  license  agreement  with  NanoCarrier  Co.,  Ltd.  (hereinafter  -  “The  License  Agreement”)  for  the
development, commercialization, and supply of ofranergene obadenovec (“VB-111”) in Japan for all indications, see notes 1(m) and 7.

In March 2019, the Company entered into an exclusive option license agreement with an animal health company for the development of VB-201 for
veterinary use, see note 7.

Since inception, the Company has incurred significant losses, and it expects to continue to incur significant expenses and losses for at least the next
several  years.  As  of  December  31,  2020,  the  Company  had  an  accumulated  deficit  of  $232.2  million.  The  Company’s  losses  may  fluctuate
significantly  from  quarter  to  quarter  and  year  to  year,  depending  on  the  timing  of  its  clinical  trials,  the  receipt  of  payments  under  any  future
collaboration agreements it may enter into, and its expenditures on other research and development activities.

As of December 31, 2020, the Company had cash, cash equivalents, short-term bank deposits and restricted cash of $30.8 million. The Company may
seek to raise more capital to pursue additional activities. The Company may seek these funds through a combination of private and public equity
offerings,  government  grants,  strategic  collaborations  and  licensing  arrangements.  Additional  financing  may  not  be  available  when  the  Company
needs it or may not be available on terms that are favorable to the Company.

  b.    Basis of preparation of the financial statements

The Company’s financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America
(“U.S. GAAP”).

Prior to 2020, the Company prepared its financial statements in accordance with International Financial Reporting Standards (“IFRS”), as issued by
the  International  Accounting  Standards  Board  (“IASB”),  as  permitted  in  the  United  States  (“U.S.”)  based  on  the  Company’s  status  as  a  foreign
private issuer as defined by the U.S. Securities and Exchange Commission (the “SEC”). During 2020, the Company decided to adopt the US GAAP
to better accommodate with the expectation of the US based investors and capital markets. There were no material IFRS to US GAAP adjustments
made upon adoption of US GAAP.

Table of Contents

VASCULAR BIOGENICS LTD.
NOTES TO THE FINANCIAL STATEMENTS (continued)

NOTE 1 – SIGNIFICANT ACCOUNTING POLICIES (continued):

  c.     Use of estimates in the preparation of financial statements

The  preparation  of  financial  statements  in  conformity  with  U.S.  GAAP  requires  management  to  make  estimates  and  assumptions  that  affect  the
reported amounts of assets and liabilities, the disclosure of contingent liabilities at the date of the financial statements and the reported amounts of
expenses during the reporting period. Actual results may differ from those estimates.

  d.    Functional and presentation currency:

1)      Functional and presentation currency

The  U.S.  dollar  (“dollar”)  is  the  currency  of  the  primary  economic  environment  in  which  the  operations  of  the  Company  are
conducted. Accordingly, the functional currency of the Company is the dollar.

2)      Transactions and balances

Transactions  and  balances  originally  denominated  in  dollars  are  presented  at  their  original  amounts.  Balances  in  non-dollar  currencies  are
translated  into  dollars  using  historical  and  current  exchange  rates  for  non-monetary  and  monetary  balances,  respectively.  For  non-dollar
transactions  and  other  items  in  the  statements  of  operations  (indicated  below),  the  following  exchange  rates  are  used:  (i)  for  transactions  -
exchange  rates  at  transaction  dates  or  average  rates;  and  (ii)  for  other  items  (derived  from  non-monetary  balance  sheet  items  such  as
depreciation and amortization, etc.) - historical exchange rates.

All foreign exchange gains and losses are presented in the statements of operations within financial income or expenses.

  e.     Cash, cash equivalents and restricted cash deposits

The Company considers as cash equivalents all short-term, highly liquid investments, which include short-term bank deposits with original maturities
of three months or less from the date of purchase that are not restricted as to withdrawal or use and are readily convertible to known amounts of cash,
in  addition  to  restricted  cash  required  to  be  set  aside  by  operating  and  financial  lease  contractual  agreements  recorded  in  current  assets  and  non-
current assets, respectively, on the balance sheet.

  f.     Property, plant and equipment:

1)    All property and equipment (including leasehold improvements) are stated at cost less accumulated depreciation and impairment. Cost includes

expenditures that are directly attributable to the acquisition of the items.

Repairs and maintenance are charged to the statement of operations during the period in which they are incurred.

2)    The assets are depreciated using the straight-line method to allocate their cost over their estimated useful lives. Annual rates of depreciation are

as follows:

Laboratory equipment
Computers
Office furniture and equipment

NOTE 1 – SIGNIFICANT ACCOUNTING POLICIES (continued):

VASCULAR BIOGENICS LTD.
NOTES TO THE FINANCIAL STATEMENTS (continued)

Leasehold improvements are depreciated using the straight-line method over the shorter of the term of the lease or the estimated useful life of
the improvements.

3)     Gains and losses on disposals are determined by comparing proceeds with the associated carrying amount. These are included in the statements

of operations.

  g.    Impairment of long-lived assets

Assets that are subject to depreciation are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount
may not be recoverable. If the sum of expected future cash flows (undiscounted and without interest charges) of the assets is less than the carrying
amount of such assets, an impairment loss would be recognized. The assets would be written down to their estimated fair values, calculated based on
the present value of expected future cash flows (discounted cash flows), or some other fair value measure.

Through December 31, 2020, no impairment has been recognized.

  h.    Deferred income tax

Deferred  taxes  are  recognized  using  the  liability  method  on  temporary  differences  arising  between  the  tax  bases  of  assets  and  liabilities  and  their
carrying amounts in the financial statements.

A valuation allowance is recognized to the extent that it is more likely than not that the deferred taxes will not be realized in the foreseeable future.
Given the Company’s losses, the Company has provided a full valuation allowance with respect to its deferred tax assets.

i.     Uncertainty in income tax

The Company follows a two-step approach in recognizing and measuring uncertain tax positions. The first step is to evaluate the tax position for
recognition by determining if the available evidence indicates that it is more likely than not that the position will be sustained based on technical
merits. If this threshold is met, the second step is to measure the tax position as the largest amount that has more than a 50% likelihood of being
realized upon ultimate settlement.

  j.     Employee benefits:

a.      Post-employment benefit obligation

Israeli  labor  laws  and  the  Company’s  agreements  require  the  Company  to  pay  retirement  benefits  to  employees  terminated  or  leaving  their
employment in certain other circumstances. Most of the Company’s employees are covered by a defined contribution plan under Section 14 of

b.      Vacation and recreation pay

Under Israeli law, each employee is entitled to vacation days and recreation pay, both computed on an annual basis. The entitlement is based on
the  length  of  the  employment  period.  The  Company  recognizes  a  liability  and  an  expense  for  vacation  and  recreation  pay  based  on  the
entitlement of each employee.

  k.    Share-based compensation

The Company accounts for employees’ and directors’ share-based payment awards classified as equity awards using the grant-date fair value method.
The fair value of share-based payment transactions is recognized as an expense over the requisite service period.

The Company elected to recognize compensation costs for awards conditioned only on continued service that have a graded vesting schedule using
the accelerated method over the related service period.

Share  based  payments  to  employees  and  directors  were  measured  by  reference  to  the  fair  value  of  the  options  and  restricted  share  (hereinafter
“RSUs”) granted at date of grant.

Until December 31, 2018, when options and RSUs were granted as consideration for services provided by consultants and other non-employees, the
grant was accounted for based on the fair value of the consideration received or the fair value of the awards issued, whichever was more reliably
measurable.  The  fair  value  of  the  awards  granted  was  measured  on  a  final  basis  at  the  end  of  the  related  service  period  and  recognized  over  the
related service period using the straight-line method.

After the adoption of ASU 2018-07 on January 1, 2019, fair value of all grants of options and RSUs is determined by reference to their fair value at
date of grant.

Service conditions and performance vesting conditions are included in assumptions about the number of options and RSU’s that are expected to vest.
The total expense is recognized over the vesting period, which is the period over which all of the specified vesting conditions are to be satisfied.

When options are exercised, the Company issues new shares, with proceeds less directly attributable transaction costs recognized as share capital (par
value) and additional paid in capital.

The Company has elected to recognize forfeitures as they occur

  l.      Contingencies:

Certain conditions may exist as of the date of the financial statements, which may result in a loss to the Company, but which will only be resolved
when one or more future events occur or fail to occur. If the assessment of a contingency indicates that it is probable that a material loss has been
incurred  and  the  amount  of  the  liability  can  be  estimated,  then  the  estimated  liability  is  recorded  as  accrued  expenses  in  the  Company’s  financial
statements. If the assessment indicates that a potential material loss contingency is not probable but is reasonably possible, or is probable but cannot
be  estimated,  then  the  nature  of  the  contingent  liability,  together  with  an  estimate  of  the  range  of  possible  loss  if  determinable  and  material  are
disclosed.

As of December 31, 2020, no contingent liabilities have been recognized.

  m.  Revenue from contracts with customers:

General

The Company recognized revenues from the License Agreement according to ASC 606, “Revenues from Contracts with Customers”.

In determining the appropriate amount of revenue to be recognized as the Company fulfills its obligations under each of its agreements, the Company
performs the following steps:

1.
2.
3.
4.
5.

identify the contract with a customer;
identify the performance obligations in the contract;
determine the transaction price;
allocate the transaction price to the performance obligations in the contract;
recognize revenue when (or as) the entity satisfies a performance obligation.

Revenues from licensing agreement

According to ASC 606, a performance obligation is a promise to provide a distinct good or service or a series of distinct goods or services. A good or
service promised to a customer is distinct if the customer can benefit from the good or service either on its own or together with other resources that
are  readily  available  to  the  customer  and  the  entity’s  promise  to  transfer  the  good  or  service  to  the  customer  is  separately  identifiable  from  other
promises in the contract.

The Company has identified two performance obligations in The License Agreement: (1) Grant of the license and use of its IP; and (2) Company’s
participation and consulting assistance services. In addition, there is a potential performance obligation regarding future manufacturing.

ASC 606 defines the ‘Transaction Price’ as the amount of consideration to which the entity expects to be entitled in exchange for transferring the
promised goods or services to a customer. The Company estimates the standalone selling prices of the services to be provided based on expected
cost-plus margin approach and uses the residual approach to estimate the selling price of the license.

The Grant of the license and use of its IP performance obligation considered to be a right to use IP in accordance with ASC 606. Therefore, revenue
is recognized at a point in time, upon transfer of control over the license to the licensee.

The Company’s participation and consulting assistance services performance obligation is recognized as revenue over the service period, based on
input method, which is costs incurred and labor hours expended.

The transaction price contains variable consideration contingent upon the licensee achieving certain milestones, as well as sales-based royalties, in
accordance with the relevant agreement. Variable payments, contingent on achieving additional milestones, are included in the transaction price based
on  most  likely  amount  method.  Amounts  included  in  the  transaction  price  are  recognized  only  when  it  is  probable  that  a  significant  reversal  of
cumulative  revenues  will  not  occur,  usually  upon  achievement  of  the  specific  milestone,  in  accordance  with  the  relevant  agreement.  Sales-based
royalties are not included in the transaction price. Rather, they are recognized as the related sale occurs, due to the specific exception of ASC 606 for
sales-based royalties in licensing of intellectual properties.

  n.    Research and development expenses:

Research and development expenses include costs directly attributable to the conduct of research and development programs, including the cost of
clinical  trials,  clinical  trial  supplies,  salaries,  share-based  compensation  expenses,  payroll  taxes  and  other  employee  benefits,  lab  expenses,
consumable equipment and consulting fees. All costs associated with research and developments are expensed as incurred.

Clinical trial expenses are charged to research and development expense as incurred. The Company accrues for expenses resulting from obligations
under  contracts  with  clinical  research  organizations  (CROs).  The  financial  terms  of  these  contracts  are  subject  to  negotiations,  which  vary  from
contract to contract and may result in payment flows that do not match the periods over which materials or services are provided. The Company’s
objective is to reflect the appropriate trial expense in the financial statements by matching the appropriate expenses with the period in which services
and efforts are expended.

  o.    Government grants

Government grants, which are received from the Israeli Innovation Authority or IIA (formerly known as the Israeli Office of Chief Scientist, or the
“OCS”)  by  way  of  participation  in  research  and  development  that  is  conducted  by  the  Company,  are  received  in  installments  as  the  program
progresses based on qualified research spending. Grants received are recognized when the grant becomes receivable, provided there was reasonable
assurance that the Company will comply with the conditions attached to the grant and there was reasonable assurance the grant will be received.

The grant is deducted from the research and development expenses as the applicable costs are incurred. Research and development expenses, net for
the years ended December 31, 2020, 2019 and 2018, include participation in research and development expenses in the amount of approximately $1.4
million, $2.7 million and $2 million, respectively.

  p.    Leases

Until December 31, 2018

Leases in which a significant portion of the risks and rewards of ownership are retained by the lessor are classified as operating leases. Payments
made under operating leases are charged to the statements of operations on a straight-line basis over the period of the lease.

Leases  of  property,  plant  and  equipment  where  the  Company,  as  lessee,  has  substantially  all  the  risks  and  rewards  of  ownership  are  classified  as
finance  leases.  Finance  leases  are  capitalized  at  the  lease’s  inception  at  the  fair  value  of  the  leased  property  or,  if  lower,  the  present  value  of  the
minimum lease payments. The corresponding rental obligations, net of finance charges, are included in short-term lease liability and long-term lease
liability. Each lease payment is allocated between the liability and finance cost. The finance cost is charged to the profit or loss over the lease period
so  as  to  produce  a  constant  periodic  rate  of  interest  on  the  remaining  balance  of  the  liability  for  each  period.  The  property,  plant  and  equipment
acquired under finance leases is depreciated over the asset’s useful life or over the shorter of the asset’s useful life and the lease term if there is no
reasonable certainty that the Company will obtain ownership at the end of the lease term.

NOTES TO THE FINANCIAL STATEMENTS (continued)

NOTE 1 – SIGNIFICANT ACCOUNTING POLICIES (continued):

After January 1, 2019

In February 2016, the FASB issued a new standard, ASC 842, related to leases to increase transparency and comparability among organizations by
requiring  the  recognition  of  ROU  assets  and  lease  liabilities  on  the  balance  sheet.  Most  prominent  among  the  changes  in  the  standard  is  the
recognition of ROU assets and lease liabilities by lessees for those leases classified as operating leases. Under the standard, disclosures are required
to meet the objective of enabling users of financial statements to assess the amount, timing, and uncertainty of cash flows arising from leases. The
Company adopted the standard as of January 1, 2019, using the simplified transition approach, therefore did not restate comparative amounts for the
year prior to first adoption. The new standard resulted in an increase of $2.7 million in operating lease ROU assets and corresponding liabilities on
the Company’s balance sheet and did not have a material impact on the Company’s statement of income or statement of cash flows.

Under ASC 842, the Company determines if an arrangement is a lease at inception. Upon initial recognition, the Company recognizes a liability at the
present value of the lease payments to be made over the lease term, and concurrently recognizes a ROU asset at the same amount of the liability,
adjusted for any prepaid or accrued lease payments, plus initial direct costs incurred in respect of the lease. Since the interest rate implicit in the lease
is not readily determinable, the incremental borrowing rate of the Company is used. The subsequent measurement depends on whether the lease is
classified as finance lease or an operating lease.

For operating leases, after lease commencement, the Company measures the lease liability at the present value of the remaining lease payments using
the discount rate determined at lease commencement. The Company subsequently measures the ROU asset at the present value of the remaining lease
payments,  adjusted  for  the  remaining  balance  of  any  lease  incentives  received,  any  cumulative  prepaid  or  accrued  rent  if  the  lease  payments  are
uneven throughout the lease term and any unamortized initial direct costs. Further, the Company will recognize lease expense on a straight-line basis
over the lease term.

For finance leases, after lease commencement, the Company measures the lease liability by increasing the carrying amount to reflect interest on the
lease liability and reducing the carrying amount to reflect the lease payments made during the period. The Company measures the ROU assets at cost
less  any  accumulated  amortization  and  any  accumulated  impairment  losses.  The  Company  amortizes  the  ROU  asset  on  a  straight-line  basis  over
approximately 7 years, unless another systematic basis better represents the pattern in which the Company expects to consume the ROU asset’s future
economic benefits.

  q.    Segment reporting

An  operating  segment  is  defined  as  a  component  that  engages  in  business  activities  whose  operating  results  are  reviewed  by  the  chief  operating
decision  maker  for  the  purpose  of  assessing  performance  and  allocating  resources  and  for  which  discrete  financial  information  is  available.  The
Company operates in one operating segment.

  r.     Loss per Ordinary Share

Basic loss per share is calculated by dividing the net loss by the weighted average number of Ordinary Shares issued and outstanding during the year.
Diluted loss per share is based upon the weighted average number of ordinary shares and of ordinary shares equivalents outstanding when dilutive.
Ordinary share equivalents include outstanding stock options and warrants which are included under the treasury stock method when dilutive. The
dilutive potential shares were not taken into account in computing loss per share in 2020, 2019 and 2018 as their effect would not have been dilutive.

  s.     Concentration of credit risks

Credit and interest risk arise from cash and cash equivalents and deposits with banks. A substantial portion of the liquid instruments of the Company
are invested in short-term deposits in a leading Israeli bank. The Company estimates that since the liquid instruments are mainly invested for short-
term and with a highly rated institution, the credit and interest risk associated with these balances is immaterial.

NOTE 2 – FAIR VALUE MEASUREMENTS

The different levels of valuation of financial instruments are defined as follows:

Level 1   Quoted prices (unadjusted) in active markets that are accessible at the measurement date for assets or liabilities. The fair value hierarchy gives

the highest priority to Level 1 inputs.

Level 2   Observable prices that are based on inputs not quoted on active markets, but corroborated by market data or active market data of similar or

identical assets or liabilities.

Level 3   Unobservable inputs are used when little or no market data is available. The fair value hierarchy gives the lowest priority to Level 3 inputs.

As of December 31, 2020, and 2019, the fair value of financial instruments (cash and cash equivalents, short term bank deposits, other current assets and
accounts payable) are approximate to their carrying value.

NOTE 3 – SHORT-TERM BANK DEPOSITS

The bank deposits in 2020 of $17,110 thousand are for terms of three months to one year and carry interest at annual rates of 0.01%-0.75%. The bank
deposits in 2019 of $27,100 thousand are for terms of three months to one year and carry interest at annual rates of 1.87%-2.15%.

NOTE 6 – SEVERANCE PAY OBLIGATIONS

VASCULAR BIOGENICS LTD.
NOTES TO THE FINANCIAL STATEMENTS (continued)

Israeli law generally requires payment of severance pay upon dismissal of an employee or upon termination of employment in certain other circumstances.
The Israel pension and severance pay liability to employees are covered mainly by regular deposits with recognized pension and severance pay funds under
the employees’ names and by purchase of insurance policies.

Most of the Company’s employees are covered by a defined contribution plan under Section 14 of the Israel Severance Pay Law. According to the plan, the
Company regularly makes payments to severance pay or pension funds without having a legal or constructive obligation to pay further contributions if the
funds does not hold sufficient assets to pay all employees in the plan the benefits relating to employee service in the current and prior periods. Neither
severance pay liability nor severance pay fund under Section 14 for such employees is recorded on the Company’s balance sheet as the Company’s relieved
of its obligation upon contribution.

For certain Israeli employees, the Company accrued severance pay liability, calculated pursuant to Israeli Severance Pay Law based on the most recent
salary of the employees multiplied by the number of years of employment as of the balance sheet date (the “Shut-Down method”). The liability is recorded
as if it was payable at each balance sheet date on an undiscounted basis

The Company’s liability with respect to Israeli employees’ is covered by monthly deposits with severance pay funds. The value of the deposited funds is
based on the cash surrender value of these policies and includes profits (or loss) accumulated through the balance sheet date. The deposited funds may be
withdrawn  only  upon  the  fulfillment  of  the  obligations  pursuant  to  Israeli  Severance  Pay  Law  or  labor  agreements.  The  amounts  funded  are  presented
separately in the balance sheet as funds in respect of employees’ rights upon retirement.

During  the  five-year  period  following  December  31,  2020,  the  Company  expects  to  pay  future  benefits  to  two  employees  upon  each  such  employee’s
normal retirement age. The Company anticipates that the benefits payable will be approximately $75 thousands.

The amounts of severance pay expenses were approximately $225 thousand, $221 thousand and $191 thousand for each of the years ended December 31,
2020, 2019 and 2018, respectively, of which approximately $225 thousand, $221 thousand and $191 thousand in the years ended December 31, 2020, 2019
and  2018,  respectively,  were  in  respect  of  the  Contribution  Plans.  Gain  on  amounts  funded  in  respect  of  employee  rights  upon  retirement  for  the  years
ended December 31, 2020, 2019 and 2018 was immaterial.

The Company expects to contribute approximately $225 thousand in the year ending December 31, 2020 to insurance companies in connection with its
severance liabilities for its operations for that year, approximately $225 thousand of which will be contributed to one or more Contribution Plans.

The above amounts were determined based on the employees’ current salary rates and the number of years’ service that will have been accumulated at their
retirement date. These amounts do not include amounts that might be paid to employees that will cease working with the Company before reaching their
normal retirement age.

Company  has  deferred  revenue  in  the  amount  of  $1.4  million  in  2020  ($0.7  million  is  classified  within  current  liabilities,  and  $0.7  million  is  classified
within non-current liabilities, which will be recognized until 2022).

All revenues recognized in 2018 were related to the Company’s participation and consulting assistance services. Revenues recognized in 2020 and 2019
were related to the Company’s participation and consulting assistance services from the License Agreement and from the option to license agreement for
the development of VB-201 for animal healthcare worldwide. The major part of revenues recognized in 2020 were included in the opening balance of the

In April 2011, the Company executed a Commercial License Agreement with Janssen Vaccines & Prevention B.V. (“Janssen”), for incorporating the
adenovirus 5 in VB-111 and other drug candidates for cancer for consideration including the following potential future payments:

an annual  license  fee  of  €100  thousand  ($123  thousand)  that  is  linked  to  Consumer  Price  Index  (in  2020,  2019  and  2018  the  Company paid
 $132 thousand, $138 thousand and $144 thousand, respectively), continuing until the termination of the agreement, which will occur upon (i)
the  later  of  the  expiration  date  of  the  last  related  patent  or  10  years  from  the  first  commercial  sale  of  VB-111  or  (ii)  the  termination  of  the
agreement by the Company, which is permitted, upon three months’ written advance notice to Janssen;

a milestone payment of €400 thousand ($492 thousand) upon receipt of the first regulatory approval for the marketing of the first indication for

In February 2013, the Company entered into an agreement with Tel Hashomer-Medical Research, Infrastructure and Services Ltd. (“Tel Hashomer”).
The agreement with Tel Hashomer provides that the Company will pay 1% of any net sales of any product covered by the intellectual property covered
under the agreement and 2% of any consideration received by the Company for granting a license or similar rights to such intellectual property. Such
amounts will be recorded as part of the Company’s cost of revenues. In addition, upon the occurrence of an exit event such as a merger, sale of all
shares  or  assets  or  the  closing  of  an  initial  public  offering  such  as  the  IPO,  the  Company  is  required  to  pay  to  Tel  Hashomer  1%  of  the  proceeds
received by the Company or its shareholders as the case may be. Royalty and all other payment obligations under this agreement will expire once the
Company has paid an aggregate sum of NIS 100 million (approximately $29 million) to Tel Hashomer by way of pay out, exit proceeds and licensing
consideration. Amounts previously paid as royalties on any net sales will not be taken into account when calculating this aggregate sum. Amounts
payable upon occurrence of an exit event are not considered to be probable until actual occurrence. Upon occurrence of such event, as such event does
not  represent  a  substantive  milestone  with  regard  to  the  Company’s  intellectual  property,  the  amount  to  be  paid  is  recorded  in  the  Statement  of
operations under research and development costs.

Until December 31, 2020, the Company paid Tel Hashomer a total amount of $747 thousand in consideration for the payments received for granting
the licenses or similar rights to this intellectual property.

c. The Company is committed to pay royalties to the Government of Israel on proceeds from sales of products in the research and development of which
the Government participates by way of grants. At time the grants were received, successful development of the related project was not assumed. In the
case of failure of the project that was partly financed by the Government of Israel, the Company is not obligated to pay any such royalties. Under the
terms  of  the  Company’s  funding  from  the  Israeli  Government,  royalties  of  3%-3.5%  are  payable  on  sales  of  products  developed  from  projects  so
funded up to 100% of the amount of the grant received by the Company (dollar linked) with the addition of an annual interest based on Libor. As of
December 31, 2020, the total additional royalty amount that may be payable by the Company, before the additional Libor interest, is approximately
$28.8 million ($36.0 million including interest). To date, the Company has paid the IIA in relation to its licenses agreement royalties of approximately
$0.5 million.

In addition,  under  the  Research  Law,  the  Company  is  prohibited  from  transferring,  including  by  way  of  license,  the  IIA-financed  technologies  and
related intellectual property rights and know-how outside of the State of Israel, except under limited circumstances and only with the approval of the
IIA Research Committee. The Company may not receive the required approvals for any proposed transfer and, even if received, may be required to
pay the IIA a portion of the consideration that it receives upon any sale of such technology to a non-Israeli entity up to 600% of the grant amounts plus
interest.

NOTE 9 – SHARE CAPITAL:

a. The Ordinary Shares confer upon their holders the following rights: (i) the right to vote in any general meeting of the Company; (ii) the right to receive
dividends; and (iii) the right to receive upon liquidation of the Company a sum equal to the nominal value of the share, and if a surplus remains, to
receive such surplus.

b. On June  25,  2018,  the  Company  entered  into  securities  purchase  agreements  related  to  the  registered  direct  offering  of  an  aggregate  of  5,904,762
ordinary shares, NIS 0.01 nominal value, at a purchase price of $2.50 per share and accompanying short-term warrants to purchase up to 2,952,381
ordinary shares and long-term warrants to purchase up to 2,952,381 ordinary shares at an additional purchase price per warrant combination of $0.125.
The combined  offering  price  of  each  ordinary  share  and  accompanying  warrants  is  $2.625  per  unit  for  aggregate  gross  proceeds  of  approximately
$15.5 million. The ordinary shares and the warrants are immediately separable and were issued separately. The net proceeds from this offering, which
closed on June 27, 2018 were $13.7 million after deducting the underwriting discounts and commissions and offering costs payable by the Company.
The short-term and long-term warrants are exercisable immediately after issuance and will expire on January 6, 2020 and June 26, 2022, respectively
at  an  exercise  price  of  $2.51  and  $3.00  per  one  ordinary  share,  respectively.  The  fair  value  of  the  separable  warrants  on  the  date  of  purchase  was
computed using the Black-Scholes model. The underlying data used for computing the fair value of the short-term and long-term warrants are mainly
as  follows:  ordinary  share  price  based  on  the  share’s  price  at  the  stock  market  on  June  25,  2018:  $2.40;  expected  volatility  based  on  Company
historical  trade:  88.0%  and  109%;  risk-free  interest  rate:  2.279%  and  2.715%  (the  risk-free  interest  rate  is  determined  based  on  rates  of  return  on
maturity of unlinked treasury bonds with time to maturity that equals the average life of the warrants); expected dividend: zero; and expected life to
exercise  of  1.5  years  and  4.0  years,  respectively.  The  consideration  was  allocated  between  ordinary  shares  and  warrants  based  on  the  ratio  of  the
warrants’ fair value and the ordinary share price.

On January 6, 2020, 2,952,381 short-term warrants related to June 25, 2018 registered direct offering were expired.

c. On May 17, 2019, the Company entered into an Equity Distribution Agreement with Oppenheimer & Co. Inc., or Oppenheimer to offer and sell from
time to time its ordinary shares, NIS 0.01 par value, having an aggregate offering price of up to $15,000,000 through Oppenheimer acting as its agent
and/or principal. For the year-ended December 31, 2020, the Company sold an aggregate of 812,470 ordinary shares under its at-the-market equity
facility. The total consideration amounted to $1,034 thousand, net of issuance costs.

d. On  May  7,  2020  and  May  11,  2020,  the  Company  entered  into  securities  purchase  agreements  with  several  institutional  investors  and  existing
shareholders  to  purchase  11,492,065  of  the  Company’s  ordinary  shares  at  a  purchase  price  of  $1.575  per  share  in  a  registered  direct  offering.  In  a
concurrent  private  placement,  the  Company  issued  to  investors  and  existing  shareholders  in  the  offering  unregistered  warrants  to  purchase  up  to
11,492,065 ordinary shares. Each warrant is exercisable immediately upon issuance at an exercise price of $1.45 per share and will remain exercisable
for  18  months  following  issuance  date.  The  offering  raised  a  total  of  $18.1  million,  with  net  proceeds  of  $16.4  million,  after  deducting  fees  and
expenses. The closing of the sale of the ordinary shares and warrants occurred on May 11, 2020 and May 13, 2020.

The fair value of the warrants is computed using the Black-Scholes option-pricing model. The underlying data used for computing the fair value of the
warrants  are  mainly  as  follows:  ordinary  share  price  based  on  the  current  price  of  an  ordinary  share:  $1.27-$1.63;  expected  volatility  based  on
Company historical trade: 74%-76%; risk-free interest rate: 0.155%-0.165%; expected dividend: zero; and expected life to exercise of 1.5 years. The
consideration was allocated between ordinary shares and warrants based on the ratio of the warrants’ fair value and the ordinary share price.

As of December 31, 2020, none of the warrants were exercised.

e. On July 29, 2020, the general meeting of the shareholders of the Company approved the increase of the authorized share capital of the Company by

80,000,000 ordinary shares to 150,000,000 ordinary shares, par value NIS 0.01 per share.

Share based compensation plans

VASCULAR BIOGENICS LTD.
NOTES TO THE FINANCIAL STATEMENTS (continued)

In February 2000, the Company’s Board of Directors approved an option plan (the “Plan”) as amended through 2008. Under the Plan, the Company
reserved  up  to  1,423,606  Ordinary  Shares  of  NIS  0.01  par  value  of  the  Company  for  allocation  to  employees  and  non-employees.  Each  option  is
exercisable  to  acquire  one  Ordinary  Share.  Any  option  granted  under  the  Plan  that  is  not  exercised  within  ten  years  from  the  date  upon  which  it
becomes exercisable, will expire.

In April 2011, the Company’s board of directors approved a new option plan (the “New Plan”). Under the New Plan, the Company reserved up to
766,958  Ordinary  Shares  (of  which  159,458  Ordinary  Shares  shall  be  taken  from  the  unallocated  pool  reserved  under  the  Plan)  for  allocation  to
employees and non-employees. Any option which was granted under the New Plan and was not exercised within twenty years from the date when it
becomes exercisable, will expire.

In  September  2014,  the  Company’s  shareholders  approved  the  adoption  of  the  Employee  Share  Ownership  and  Option  Plan  (2014)  (“2014  Plan”)
effective  as  of  the  closing  of  the  public  offering.  Under  the  2014  Plan,  the  Company  reserved  up  to  928,000  Ordinary  Shares  (of  which  28,000
Ordinary Shares shall be taken from the unallocated pool reserved under the New Plan). The Ordinary Shares to be issued upon exercise of the options
confer the same rights as the other Ordinary Shares of the Company, immediately upon allotment. Any option which was granted under the 2014 Plan
and was not exercised within twenty years from the date when it becomes exercisable, will expire.

Option exercise prices and vesting periods shall be as determined by the board of directors of the Company on the date of the grant.

The options are subject to the terms stipulated by section 102(b)(2) of the Ordinance. According to these provisions, the Company will not be allowed
to claim as an expense for tax purposes the amounts credited to the employees as a capital gain benefit in respect of the options granted.

Options granted to related parties or non-employees of the Company are governed by Section 3(i) of the Ordinance. The Company will be allowed to
claim as an expense for tax purposes the amounts equal to the expenses it recorded in the financial statements in the year in which the related parties
or non-employees exercised the options into shares.

All of the options granted in 2018, 2019, 2020 will vest by 4 years with 25% on the first-year anniversary; the remaining 75% at 1/12 of the options at the
end of each quarter over the course of the last 3 years.

The fair value of the options on the date of grant was computed using the Black-Scholes model. Fair value of the options was estimated using the expected
volatility. The risk-free interest rate was determined based on rates of return on maturity of unlinked treasury bonds with time to maturity that equals the
average life of the options.

The fair value of the Company’s stock options and RSUs granted for the years ended December 31, 2020, 2019 and 2018 was estimated using the following

NOTE 10 – TAXES ON INCOME

a. Measurement of results for tax purposes

VASCULAR BIOGENICS LTD.
NOTES TO THE FINANCIAL STATEMENTS (continued)

The  Company  as  a  “foreign-investment  company”  measures  its  results  for  tax  purposes  in  dollar  based  on  Income  Tax  Regulations  (Bookkeeping
Principles of Foreign Invested Companies and of Certain Partnerships and the Determination of Their Taxable Income), 1986.

b. Tax rates

The Company is taxed according to Israeli tax laws. The taxable income of the Company, other than income from Benefited Enterprises (see c below),
is subject to the regular Israeli corporate tax rate, which is currently 23%.

c. Tax benefits under the Law for the Encouragement of Capital Investments, 1959 (the “Investment Law”)

Under  the  Investment  Law,  including  Amendment  No.  60  to  the  Investment  Law  that  was  published  in  April  2005,  by  virtue  of  the  Benefited
Enterprise program for certain of its production facilities, the Company may be entitled to various tax benefits.

The main benefit arising from such status is the reduction in tax rates on income derived from a Benefited Enterprise. The extent of such benefits
depends  on  the  location  of  the  enterprise.  Since  the  Company’s  facilities  are  not  located  in  “national  development  zone  A,”  income  derived  from
Benefited Enterprises will be tax exempt for a period of two years and then have a reduced tax rate for a period of up to an additional eight years.

The  period  of  tax  benefits,  as  described  above,  is  limited  to  12  years  from  the  beginning  of  the  Benefited  Enterprise  election  year  (2012).  As  of
December 31, 2020, the period of benefits has not yet commenced.

In the event of distribution or deemed distribution of dividends from income which was tax exempt as above, the amount distributed will be subject to
the tax rate it was exempted from.

The Company is entitled to claim accelerated depreciation in respect of equipment used by the Benefited Enterprises during five tax years.

Entitlement  to  the  above  benefits  is  conditioned  upon  the  Company  fulfilling  the  conditions  stipulated  by  the  Investment  Law  and  regulations
published thereunder.

In  the  event  of  failure  to  comply  with  these  conditions,  the  benefits  may  be  canceled  and  the  Company  may  be  required  to  apply  the  regular  tax
depreciation  rates  and  pay  tax  on  the  income  in  question  at  the  regular  corporate  tax  rates  with  the  addition  of  linkage  differences  to  the  Israeli
consumer price index and interest.

The  Investment  Law  was  amended  as  part  of  the  Economic  Policy  Law  for  the  years  2011-2012  (the  “Amendment”),  which  became  effective  on
January 1, 2011.

The  Amendment  sets  alternative  benefit  tracks  to  the  ones  currently  in  place  under  the  provisions  of  the  Investment  Law,  including  a  reduced
corporate tax rate. Tax rate for “Preferred Enterprise” income of companies not located in national development zone A is 16% for fiscal year 2014
and thereafter.

NOTE 10 – TAXES ON INCOME (continued):

VASCULAR BIOGENICS LTD.
NOTES TO THE FINANCIAL STATEMENTS (continued)

The benefits are granted to companies that qualify under criteria set forth in the Investment Law; for the most part, those criteria are similar to the
criteria that have existed in the Investment Law prior to its amendment and the benefit period is unlimited in time. However, in accordance with the
Amendment, the classification of licensing income as Preferred income may be subject to the issuance of a pre-ruling by the Israel Tax Authority.

Additional  amendments  to  the  Investment  Law  became  effective  in  January  2017  (the  “2017  Amendment”).  Under  the  2017  Amendment,  and
provided the conditions stipulated therein are met, income derived by Preferred Companies from ‘Preferred Technological Enterprises’ (“PTE”) (as
defined in the 2017 Amendment), would be subject to reduced corporate tax rates of 7.5% in Development Zone “A” and 12% elsewhere, or 6% in
case  of  a  ‘Special  Preferred  Technological  Enterprise’  (“SPTE”)  as  defined  in  the  2017  Amendment)  regardless  of  the  company’s  geographical
location within Israel. A Preferred Company distributing dividends from income derived from its PTE or SPTE, would subject the recipient to a 20%
tax  (or  lower,  if  so  provided  under  an  applicable  tax  treaty).  The  2017  Amendment  further  provides  that,  in  certain  circumstances,  a  dividend
distributed to a corporate shareholder who is not an Israeli resident for tax purposes would be subject to a 4% tax (inter alia, if the amount of foreign
investors in the distributing company exceeds 90%). Such taxes would generally be withheld at source by the distributing company.

On  June  14,  2017,  the  Encouragement  of  Capital  Investments  Regulations  (Preferred  Technology  Income  and  Capital  Profits  for  a  Technological
Enterprise), 2017 (the “Regulations”) were published, which adopted Action 5 under the base erosion and profit shifting (“BEPS”) regulations. The
Regulations  describe,  inter  alia,  the  mechanism  used  to  determine  the  calculation  of  the  benefits  under  the  PTE  and  under  the  SPTE  Regime  and
determine  certain  requirements  relating  to  documentation  of  intellectual  property  for  the  purpose  of  the  PTE.  According  to  these  provisions,  a
company  that  complies  with  the  terms  under  the  PTE  regime  may  be  entitled  to  certain  tax  benefits  with  respect  to  income  generated  during  the
company’s  regular  course  of  business  and  derived  from  the  preferred  intangible  asset  (as  determined  in  the  Investments  Law),  excluding  income
derived from intangible assets used for marketing and income attributed to production activity. In the event that intangible assets used for marketing
purposes generate over 10% of the PTE’s income, the relevant portion, calculated using a transfer pricing study, would be subject to regular corporate
income tax. If such income does not exceed 10%, the PTE will not be required to exclude the marketing income from the PTE’s total income. The
Regulations set a presumption of direct production expenses plus 10% with respect to income related to production, which can be countered by the
results  of  a  supporting  transfer  pricing  study.  Tax  rates  applicable  to  such  production  income  expenses  will  be  similar  to  the  tax  rates  under  the
Preferred Enterprise regime, to the extent such income would be considered as eligible. In order to calculate the preferred income, the PTE is required
to take into account the income and the research and development expenses that are attributed to each single preferred intangible asset. Nevertheless,
it should be noted that the transitional provisions allow companies to take into account the income and research and development expenses attributed
to all of the preferred intangible assets they have. Under the Regulations, the Company’s corporate tax rate is expected to be between 12% to 16%.

Under the transitional provisions of the Investment Law, a company is allowed to continue to enjoy the tax benefits available under the Investment
Law prior to its amendment until the end of the period of benefits, as defined in the Investment Law.

In each year during the period of benefits of its Benefited Enterprise, the Company will be able to opt for application of the Amendment, thereby
making available to itself the tax rate described above. The Company’s election to apply the Amendment is irrevocable.

As of December 31, 2020, the Company’s management decided not to adopt the application of the Amendment.

There is no assurance that future taxable income of the Company will qualify as Benefited, Preferred or Preferred Technological income or that the
benefits described above will be available to the Company in the future.

NOTE 10 – TAXES ON INCOME (continued):

d. Losses for tax purposes carried forward to future years

The balance of carry forward losses as of December 31, 2020 is $198.1 million.

Under Israeli tax laws, carryforward tax losses have no expiration date.

Deferred  tax  assets  on  losses  for  tax  purposes  carried  forward  to  subsequent  years  are  recognized  if  utilization  of  the  related  tax  benefit  against  a
future taxable income is expected.

As the achievement of required future taxable income is not likely, the Company recorded a full valuation allowance.

e. Tax assessments

The Company has tax assessments that are considered to be final through tax year 2015.

f. Deferred Taxes

The  following  table  presents  summary  of  information  concerning  the  Company’s  deferred  taxes  as  of  the  periods  ending  December  31,  2020  and
December 31, 2019.

The  main  reconciling  item  between  the  statutory  tax  rate  of  the  Company  and  the  effective  rate  is  the  provision  for  a  full  valuation  allowance  in
respect  of  tax  benefits  from  carry  forward  tax  losses  due  to  the  uncertainty  of  the  realization  of  such  tax  benefits  and  the  Company’s  three  year

NOTE 13 – SUBSEQUENT EVENT:

VASCULAR BIOGENICS LTD.
NOTES TO THE FINANCIAL STATEMENTS (continued)

a. On  January  14,  2021,  the  Company  entered  into  an  ordinary  share  purchase  agreement  (Agreement)  of  up  to  $20  million  of  the  Company’s
ordinary shares, par value NIS 0.01 per share, with Aspire Capital Fund, LLC.  The ordinary shares may be sold from time to time based on the
Company’s notice to Aspire Capital over the 30-month term of the purchase Agreement.

b. During January  and  February  2021  the  Company  issued  6,947,272  ordinary  shares  out  of  which  (a)  4,861,906  shares  issued  from  exercise  of
warrants; (b) 1,285,366 shares from the At-The-Market (ATM); and (c) sale of 800,000 shares to Aspire Capital Fund, LLC under the Agreement.
The accumulated gross proceeds from the sale of the above shares is approximately $12,345 thousand.

Regarding the ATM sales the Company failed to file a prospectus supplement specifying details regarding such sales. This may have constituted a
 violation  of  Section  5  of  the  Securities  Act  and  may  give  rise  to  liability  under  Section  12  of  the  Securities  Act    (which  generally  provides  a
rescission remedy for offers and sales of securities in violation of Section 5) as well  as potential liability under the anti-fraud provisions of federal
and state securities laws and state rescission laws. 

In such event, anyone who acquired such ordinary shares would have a right to rescind the purchase. If all the  shareholders who acquired ordinary
shares demanded rescission, the maximum that the Company would be obligated to repay would be approximately $3,500 thousand, plus interest.
Out of the $3,500 thousand, there was an identified buyer of approximately $1,900. That buyer has agreed to waive his rescission right and signed
a  respective  waiver.  The  Securities  Act  generally  requires  that  any  claim  brought   for  a  violation  of  Section  5  of  the  Securities  Act  be  brought
within one year of the violation. Additionally, if it is  determined that such sales did in fact violate the Securities Act, the Company may become
subject  to  fines  and  penalties   imposed  by  the  SEC  and  state  securities  agencies.   Management  is  evaluating  the  impact  of  this  matter  on  the
Company including the penalty to be recorded as such transactions occurred in 2021.

DESCRIPTION OF SECURITIES

Exhibit 2.7

The following description of the capital stock of Vascular Biogenics Ltd. (“us,” “our,” “we” or the “Company”) is a summary of the rights of our ordinary
shares and certain provisions of our articles of association currently in effect. This summary does not purport to be complete and is qualified in its entirety
by the provisions of our articles of association previously filed with the Securities and Exchange Commission and incorporated by reference as an exhibit
to the Annual Report on Form 20-F of which this Exhibit 2.7 is a part, as well as to the applicable provisions of the Israeli Companies Law. We encourage
you to read our articles of associations and applicable portions of the Israeli Companies Law carefully.

General

Authorized Capital

Our authorized share capital consists solely of 150,000,000 ordinary shares, par value NIS 0.01 per share. All of our outstanding ordinary shares are validly
issued, fully paid and non-assessable. Our ordinary shares are not redeemable and do not have any preemptive rights.

Registration Number and Purpose of the Company

Our  registration  number  with  the  Israeli  Registrar  of  Companies  is  51-289976-6.  Our  purpose  as  set  forth  in  our  amended  and  restated  articles  of
association is to engage in any lawful activity.

Voting Rights and Conversion

All ordinary shares will have identical voting and other rights in all respects.

Transfer of Shares

Our fully paid ordinary shares are issued in registered form and may be freely transferred under our amended and restated articles of association, unless the
transfer  is  restricted  or  prohibited  by  another  instrument,  applicable  law  or  the  rules  of  a  stock  exchange  on  which  the  shares  are  listed  for  trade.  The
ownership or voting of our ordinary shares by non-residents of Israel is not restricted in any way by our amended and restated articles of association or the
laws of the State of Israel, except for ownership by nationals of some countries that are, or have been, in a state of war with Israel.

 
 
 
 
 
 
 
 
 
 
 
 
 
 
Election of Directors

Our ordinary shares do not have cumulative voting rights for the election of directors. As a result, the holders of a majority of the voting power represented
at a shareholders meeting have the power to elect all of our directors, subject to the special approval requirements for external directors.

Under our amended and restated articles of association, our board of directors must consist of not less than three, not including two external directors, but
no more than nine directors (including the external directors). Pursuant to our amended and restated articles of association, other than the external directors,
for whom special election requirements apply under the Companies Law, the vote required to appoint a director is a simple majority vote of holders of our
voting shares, participating and voting at the relevant meeting. Each director will serve until his or her successor is duly elected and qualified or until his or
her earlier death, resignation or removal by a vote of the majority voting power of our shareholders at a general meeting of our shareholders or until his or
her office expires by operation of law, in accordance with the Companies Law. In addition, our amended and restated articles of association allow our board
of directors to appoint directors to fill vacancies on the board of directors to serve for a term of office equal to the remaining period of the term of office of
the directors(s) whose office(s) have been vacated. External directors are elected for an initial term of three years, may be elected for additional terms of
three years each under certain circumstances, and may be removed from office pursuant to the terms of the Companies Law. Following the adoption by the
Company of certain reliefs provided under the Companies Law, the Company is exempt from the requirement to appoint external directors.

Dividend and Liquidation Rights

We  may  declare  a  dividend  to  be  paid  to  the  holders  of  our  ordinary  shares  in  proportion  to  their  respective  shareholdings.  Under  the  Companies  Law,
dividend distributions are determined by the board of directors and do not require the approval of the shareholders of a company unless the company’s
articles of association provide otherwise. Our amended and restated articles of association do not require shareholder approval of a dividend distribution
and provide that dividend distributions may be determined by our board of directors.

Pursuant to the Companies Law, the distribution amount is limited to the greater of retained earnings or earnings generated over the previous two years,
according to our then last reviewed or audited financial statements, provided that the date of the financial statements is not more than six months prior to
the date of the distribution, or we may otherwise only distribute dividends that do not meet such criteria only with court approval. In each case, we are only
permitted to distribute a dividend if our board of directors and the court, if applicable, determines that there is no reasonable concern that payment of the
dividend will prevent us from satisfying our existing and foreseeable obligations as they become due.

In the event of our liquidation, after satisfaction of liabilities to creditors, our assets will be distributed to the holders of our ordinary shares in proportion to
their shareholdings. This right, as well as the right to receive dividends, may be affected by the grant of preferential dividend or distribution rights to the
holders of a class of shares with preferential rights that may be authorized in the future.

Exchange Controls

There  are  currently  no  Israeli  currency  control  restrictions  on  remittances  of  dividends  on  our  ordinary  shares,  proceeds  from  the  sale  of  the  shares  or
interest or other payments to non- residents of Israel, except for shareholders who are subjects of countries that are, or have been, in a state of war with
Israel.

 
 
 
 
 
 
 
 
 
 
 
 
Shareholder Meetings

Under Israeli law, we are required to hold an annual general meeting of our shareholders once every calendar year that must be held no later than 15 months
after the date of the previous annual general meeting. All meetings other than the annual general meeting of shareholders are referred to in our amended
and restated articles of association as extraordinary general meetings. Our board of directors may call extraordinary general meetings whenever it sees fit,
at such time and place, within or outside of Israel, as it may determine. In addition, the Companies Law provides that our board of directors is required to
convene an extraordinary general meeting upon the written request of (i) any two of our directors or one- quarter of the members of our board of directors
or (ii) one or more shareholders holding, in the aggregate, either (a) 5% or more of our outstanding issued shares and 1% of our outstanding voting power
or (b) 5% or more of our outstanding voting power. One or more shareholders, holding 1% or more of the outstanding voting power, may ask the board to
add an item to the agenda of a prospective meeting, if the proposal merits discussion at the general meeting.

Subject  to  the  provisions  of  the  Companies  Law  and  the  regulations  promulgated  thereunder,  shareholders  entitled  to  participate  and  vote  at  general
meetings are the shareholders of record on a date to be decided by the board of directors, which may be between four and 40 days prior to the date of the
meeting.  Furthermore,  the  Companies  Law  requires  that  resolutions  regarding  the  following  matters  must  be  passed  at  a  general  meeting  of  our
shareholders:

● amendments to our articles of association;

● appointment or termination of our auditors;

● appointment of external directors;

● approval of certain related party transactions;

● increases or reductions of our authorized share capital;

● a merger; and

● the exercise of our board of directors’ powers by a general meeting, if our board of directors is unable to exercise its powers and the exercise of

any of its powers is required for our proper management.

The  Companies  Law  and  our  amended  and  restated  articles  of  association  require  that  a  notice  of  any  annual  general  meeting  or  extraordinary  general
meeting be provided to shareholders at least 21 days prior to the meeting and if the agenda of the meeting includes the appointment or removal of directors,
the approval of transactions with office holders or interested or related parties, or an approval of a merger, notice must be provided at least 35 days prior to
the meeting.

Under the Companies Law and our amended and restated articles of association, shareholders are not permitted to take action via written consent in lieu of
a meeting.

Voting Rights

Quorum Requirements

Pursuant  to  our  amended  and  restated  articles  of  association,  holders  of  our  ordinary  shares  have  one  vote  for  each  ordinary  share  held  on  all  matters
submitted to a vote before the shareholders at a general meeting. As a foreign private issuer, the quorum required for our general meetings of shareholders
consists of at least two shareholders present in person, by proxy or written ballot who hold or represent between them at least 25% of the total outstanding
voting rights. A meeting adjourned for lack of a quorum is generally adjourned to the same day in the following week at the same time and place or to a
later time or date if so specified in the notice of the meeting. At the reconvened meeting, any two or more shareholders present in person or by proxy shall
constitute a lawful quorum.

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Vote Requirements

Our amended and restated articles of association provide that all resolutions of our shareholders require a simple majority vote, unless otherwise required
by  the  Companies  Law  or  by  our  amended  and  restated  articles  of  association.  Under  the  Companies  Law,  each  of  (i)  the  approval  of  an  extraordinary
transaction with a controlling shareholder and (ii) the terms of employment or other engagement of the controlling shareholder of the company or such
controlling shareholder’s relative (even if not extraordinary) requires, the approval of our audit committee, our board of directors and a Special Majority, in
that  order.  Under  our  amended  and  restated  articles  of  association,  the  alteration  of  the  rights,  privileges,  preferences  or  obligations  of  any  class  of  our
shares  requires  a  simple  majority  vote  of  the  class  so  affected  (or  such  other  percentage  of  the  relevant  class  that  may  be  set  forth  in  the  governing
documents  relevant  to  such  class),  in  addition  to  the  ordinary  majority  vote  of  all  classes  of  shares  voting  together  as  a  single  class  at  a  shareholder
meeting. An exception to the simple majority vote requirement is a resolution for the voluntary winding up, or an approval of a scheme of arrangement or
reorganization,  of  the  company  pursuant  to  Section  350  of  the  Companies  Law,  which  requires  the  approval  of  holders  of  75%  of  the  voting  rights
represented at the meeting, in person, by proxy or by voting deed and voting on the resolution.

Access to Corporate Records

Under  the  Companies  Law,  shareholders  are  provided  access  to:  minutes  of  our  general  meetings;  our  shareholders  register  and  principal  shareholders
register, articles of association and financial statements; and any document that we are required by law to file publicly with the Israeli Companies Registrar
or  the  Israel  Securities  Authority.  In  addition,  shareholders  may  request  to  be  provided  with  any  document  related  to  an  action  or  transaction  requiring
shareholder approval under the related party transaction provisions of the Companies Law. We may deny this request if we believe it has not been made in
good faith or if such denial is necessary to protect our interest or protect a trade secret or patent.

Modification of Class Rights

Under the Companies Law and our amended and restated articles of association, the rights attached to any class of share, such as voting, liquidation and
dividend rights, may be amended by adoption of a resolution by the holders of a majority of the shares of that class present at a separate class meeting, or
otherwise in accordance with the rights attached to such class of shares, as set forth in our amended and restated articles of association.

Acquisitions under Israeli Law

Full Tender Offer

A person wishing to acquire shares of an Israeli public company and who would as a result hold over 90% of the target company’s issued and outstanding
share  capital  is  required  by  the  Companies  Law  to  make  a  tender  offer  to  all  of  the  company’s  shareholders  for  the  purchase  of  all  of  the  issued  and
outstanding shares of the company. A person wishing to acquire shares of a public Israeli company and who would as a result hold over 90% of the issued
and outstanding share capital of a certain class of shares is required to make a tender offer to all of the shareholders who hold shares of the relevant class
for the purchase of all of the issued and outstanding shares of that class. If the shareholders who do not accept the offer hold less than 5% of the issued and
outstanding share capital of the company or of the applicable class, and more than half of the shareholders who do not have a personal interest in the offer
accept the offer, all of the shares that the acquirer offered to purchase will be transferred to the acquirer by operation of law. However, a tender offer will
also be accepted if the shareholders who do not accept the offer hold less than 2% of the issued and outstanding share capital of the company or of the
applicable class of shares.

Upon a successful completion of such a full tender offer, any shareholder that was an offeree in such tender offer, whether such shareholder accepted the
tender offer or not, may, within six months from the date of acceptance of the tender offer, petition an Israeli court to determine whether the tender offer
was for less than fair value and that the fair value should be paid as determined by the court. However, under certain conditions, the offeror may include in
the terms of the tender offer that an offeree who accepted the offer will not be entitled to petition the Israeli court as described above.

If (a) the shareholders who did not respond or accept the tender offer hold at least 5% of the issued and outstanding share capital of the company or of the
applicable class or the shareholders who accept the offer constitute less than a majority of the offerees that do not have a personal interest in the acceptance
of the tender offer, or (b) the shareholders who did not accept the tender offer hold 2% or more of the issued and outstanding share capital of the company
(or of the applicable class), the acquirer may not acquire shares of the company that will increase its holdings to more than 90% of the company’s issued
and outstanding share capital or of the applicable class from shareholders who accepted the tender offer.

 
 
 
 
 
 
 
 
 
 
 
 
 
 
Special Tender Offer

The Companies Law provides that an acquisition of shares of an Israeli public company must be made by means of a special tender offer if as a result of the
acquisition the purchaser would become a holder of 25% or more of the voting rights in the company. This requirement does not apply if there is already
another holder of at least 25% of the voting rights in the company. Similarly, the Companies Law provides that an acquisition of shares in a public company
must be made by means of a special tender offer if, as a result of the acquisition, the purchaser would become a holder of more than 45% of the voting
rights in the company, provided that there is no other shareholder of the company who holds more than 45% of the voting rights in the company, subject to
certain exceptions.

A special tender offer must be extended to all shareholders of a company but the offeror is not required to purchase shares representing more than 5% of the
voting power attached to the company’s outstanding shares, regardless of how many shares are tendered by shareholders. A special tender offer may be
consummated only if (i) outstanding shares representing at least 5% of the voting power of the company will be acquired by the offeror and (ii) the number
of shares tendered in the offer exceeds the number of shares whose holders objected to the offer (excluding the purchaser, controlling shareholders, holders
of 25% or more of the voting rights in the company or any person having a personal interest in the acceptance of the tender offer). If a special tender offer
is accepted, then the purchaser or any person or entity controlling it or under common control with the purchaser or such controlling person or entity may
not make a subsequent tender offer for the purchase of shares of the target company and may not enter into a merger with the target company for a period
of one year from the date of the offer, unless the purchaser or such person or entity undertook to effect such an offer or merger in the initial special tender
offer.

Merger

The  Companies  Law  permits  merger  transactions  if  approved  by  each  party’s  board  of  directors  and,  unless  certain  requirements  described  under  the
Companies Law are met, by a majority vote of each party’s shareholders, and, in the case of the target company, a majority vote of each class of its shares,
voted on the proposed merger at a shareholders meeting.

For purposes of the shareholder vote, unless a court rules otherwise, the merger will not be deemed approved if a majority of the votes of shares represented
at the shareholders meeting that are held by parties other than the other party to the merger, or by any person (or group of persons acting in concert) who
holds (or hold, as the case may be) 25% or more of the voting rights or the right to appoint 25% or more of the directors of the other party, vote against the
merger. If, however, the merger involves a merger with a company’s own controlling shareholder or if the controlling shareholder has a personal interest in
the  merger,  then  the  merger  is  instead  subject  to  the  same  Special  Majority  approval  that  governs  all  extraordinary  transactions  with  controlling
shareholders. A Special Majority approval constitutes shareholder approval by a majority vote of the shares present and voting at a meeting of shareholders
called for such purpose, provided that either: (a) such majority includes at least a majority of the shares held by all shareholders who are not controlling
shareholders and do not have a personal interest in such compensation arrangement; or (b) the total number of shares of non-controlling shareholders and
shareholders  who  do  not  have  a  personal  interest  in  the  compensation  arrangement  and  who  vote  against  the  arrangement  does  not  exceed  2%  of  the
company’s aggregate voting rights.

If the transaction would have been approved by the shareholders of a merging company but for the separate approval of each class or the exclusion of the
votes of certain shareholders as provided above, a court may still approve the merger upon the request of holders of at least 25% of the voting rights of a
company, if the court holds that the merger is fair and reasonable, taking into account the value of the parties to the merger and the consideration offered to
the shareholders of the target company.

Upon the request of a creditor of either party to the proposed merger, the court may delay or prevent the merger if it concludes that there exists a reasonable
concern  that,  as  a  result  of  the  merger,  the  surviving  company  will  be  unable  to  satisfy  the  obligations  of  the  merging  entities,  and  may  further  give
instructions to secure the rights of creditors.

 
 
 
 
 
 
 
 
 
 
 
In addition, a merger may not be consummated unless at least 50 days have passed from the date on which a proposal for approval of the merger was filed
by each party with the Israeli Registrar of Companies and at least 30 days have passed from the date on which the merger was approved by the shareholders
of each party.

Anti-Takeover Measures under Israeli Law

The  Companies  Law  allow  us  to  create  and  issue  shares  having  rights  different  from  those  attached  to  our  ordinary  shares,  including  shares  providing
certain  preferred  rights  with  respect  to  voting,  distributions  or  other  matters  and  shares  having  preemptive  rights.  No  preferred  shares  are  currently
authorized under our amended and restated articles of association. In the future, if we do authorize, create and issue a specific class of preferred shares,
such class of shares, depending on the specific rights that may be attached to it, may have the ability to frustrate or prevent a takeover or otherwise prevent
our  shareholders  from  realizing  a  potential  premium  over  the  market  value  of  their  ordinary  shares.  The  authorization  and  designation  of  a  class  of
preferred  shares  will  require  an  amendment  to  our  amended  and  restated  articles  of  association,  which  requires  the  prior  approval  of  the  holders  of  a
majority of the voting power attaching to our issued and outstanding shares at a general meeting. The convening of the meeting, the shareholders entitled to
participate and the majority vote required to be obtained at such a meeting will be subject to the requirements set forth in the Companies Law as described
above in “Voting Rights.”

Borrowing Powers

Pursuant to the Companies Law and our amended and restated articles of association, our board of directors may exercise all powers and take all actions
that are not required under law or under our amended and restated articles of association to be exercised or taken by our shareholders, including the power
to borrow money for company purposes.

Changes in Capital

Our amended and restated articles of association enable us to increase or reduce our share capital. Any such changes are subject to the provisions of the
Companies Law and must be approved by a resolution duly passed by our shareholders at a general meeting by voting on such change in the capital. In
addition,  transactions  that  have  the  effect  of  reducing  capital,  such  as  the  declaration  and  payment  of  dividends  in  the  absence  of  sufficient  retained
earnings or profits, require the approval of both our board of directors and an Israeli court.

Warrants

As  of  the  date  hereof,  warrants  to  purchase  4,234,313  ordinary  shares  were  issued  and  outstanding  at  a  weighted  average  exercise  price  of  $4.31  per
ordinary share. The expiration dates of these warrants range from April 1, 2021 to June 25, 2022.

Transfer Agent and Registrar

Our transfer agent in the United States is American Stock Transfer & Trust Company, LLC.

Listing

Our ordinary shares are listed on The NASDAQ Global Market under the symbol “VBLT.”

FOREIGN EXCHANGE CONTROLS AND OTHER LIMITATIONS

Israeli law limits foreign currency transactions and transactions between Israeli and non-Israeli residents. The Controller of Foreign Exchange at the Bank
of Israel, through “general” and “special” permits, may regulate or waive these limitations. In May 1998, the Bank of Israel liberalized its foreign currency
regulations by issuing a new “general permit” providing that foreign currency transactions are generally permitted, although some restrictions still apply.
Under the new general permit, all foreign currency transactions must be reported to the Bank of Israel, and a foreign resident must report to his financial
mediator about any contract for which Israeli currency is being deposited in, or withdrawn from, his account.

The State of Israel generally does not restrict the ownership or voting of ordinary shares of Israeli entities by non-residents of Israel, except with respect to
subjects of countries that are in a state of war with Israel.
