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,  2021,  2020  and  2019  in  this  Annual  Report  have  been  prepared  in  accordance  in
accordance with U.S. GAAP.

Summary of Risk Factors

Investing in our common shares involves a high degree of risk. You should carefully consider the risks summarized below and other risks that we face, a
detailed discussion of which can be found under “Item 3. Key Information-D. Risk Factors” below, together with other information in this annual report on
Form 20-F and our other filings with the Securities and Exchange Commission, or SEC. This summary list of risks is not exhaustive of the factors that may
affect any of our forward-looking statements and our business and financial results. If any of these risks actually occur, our business, financial condition
and financial performance would likely be materially adversely affected. In such case, the trading price of our common shares would likely decline and you
may lose part or all of your investment. Below is a summary of some of the principal risks we face:

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

future.

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

● 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 have received and may continue to receive Israeli or other 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.

● We have been selected for €17.5 million of funding from the Horizon Europe EIC Accelerator Program, which funding is subject to a lengthy

process, including finalization of agreements, prior to receipt, which we may not successfully achieve.

● We are  highly  dependent  on  the  success  of  ofra-vec  in  oncology  applications,  and  our  platform  technologies in general, and we cannot be
certain  that  any  of  them  will  receive  regulatory  approval  or  be  commercialized.  Any  failure  to  successfully  develop,  obtain  regulatory
approval for and commercialize ofra-vec 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.

● 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 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.

● 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.

● 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  U.S.  Food  and  Drug  Administration,  or  FDA,  and  the  European
Medicines Agency, or EMA, may require us to conduct additional clinical trials, or evaluate subjects for an additional follow-up period.

● Legislative and regulatory activity may exert downward pressure on potential pricing and reimbursement for any of our product candidates, if

approved, that could materially affect the opportunity to commercialize.

● 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  intend  to  at  least  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.

● Legislative and regulatory activity may exert downward pressure on potential pricing and reimbursement for any of our product candidates, if

approved, that could materially affect the opportunity to commercialize.

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

personnel.

● Pandemics,  such  as  the  ongoing  COVID-19  pandemic,  could  have  an  adverse  impact  on  our  developmental  programs  and  our  financial

condition.

● 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.

● 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.

● We are currently 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 expect to lose our foreign private issuer status, which will require us to comply with the Exchange Act’s domestic reporting regime and

cause us to incur significant legal, accounting and other expenses, even if we are able to qualify as a “smaller reporting company.”

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 and “Item 5. Operating and Financial Review and Prospects.” 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  $29.9  million,  $24.2  million  and  $19.4  million  for  the  years  ended  December  31,  2021,  2020  and  2019,
respectively. As of December 31, 2021, we had an accumulated deficit of $262.1 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, which did
not meet the primary endpoint in such trial and it will be a few years, if ever, before we have a product candidate ready for commercialization. Even if our
current Phase 3 trial or future clinical trials are successful and we obtain regulatory approval to market a product, our future revenues will depend upon the
size  of  any  markets  in  which  such  product  receives  approval,  and  our  ability  to  achieve  sufficient  market  acceptance,  reimbursement  from  third-party
payers and adequate market share for any approved product 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, preclinical, and clinical development activities for our product candidates;

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

● initiate additional research, 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;

● expand our operations in the United States;

● seek to identify and validate additional product candidates;

● acquire or in-license other product candidates and technologies;

● 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;

● transition from being a foreign private issuer to a U.S. reporting 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, preclinical, and clinical development activities for our product candidates;

● successful outcomes from our current and future trials evaluating our product candidates;

● obtaining regulatory and marketing approvals for product candidates for which we complete successful 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;

● 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 FDA and
EMA and other foreign regulatory authorities, and obtaining approval for our manufacturing facility;

● 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 are 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  ofra-vec  (ofranergene  obadenovec,  also  known  as  VB-111)  for  oncology  indications,  and  VB-601  for  inflammatory
applications.  We  intend  to  advance  these  product  candidates  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,  2021,  our  cash  and  cash  equivalents  and  short-term  bank  deposits  were  $53.5  million.  As  of  the  date  of  this  Annual  Report,  we
estimate that the balance of cash, cash equivalents and short-term bank deposits at December 31, 2021 will be sufficient to fund our operations for at least
twelve months from the date of the readout of top-line PFS data from the Phase 3 OVAL trial (data we anticipate receiving in the second half of 2022).
However, our operating plan may change as a result of many factors, 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 we will require additional capital to commercialize and market any products that receive regulatory approval, including full
pre-commercialization activities. Raising funds in the current economic environment may present additional challenges. Global health concerns resulting
from the outbreak of the coronavirus and worldwide macroeconomic turmoil 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 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,  2021  we  had  received  an  aggregate  of  $29.2  million  in  grants  from  the  Israeli  Innovation  Authority,  or  IIA.  Under  the  Israel
Encouragement of Research and Development in Industries, or 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 the VTS platform technology from
which  our  product  candidate,  ofra-vec,  is  derived,  at  least  in  part,  with  funds  from  these  grants,  and  accordingly  we  would  be  obligated  to  pay  these
royalties on sales of product candidates derived from the VTS technology developed using these IIA grants that achieve regulatory approval, such as ofra-
vec. We also developed another technology utilizing IIA funds, which we do not expect to be able to commercialize. The maximum aggregate royalties
paid  for  each  technology  or  program  separately,  generally  cannot  exceed  100%  of  the  grants  made  to  us  for  such  technology  or  program,  plus  annual
interest. As of December 31, 2021, the balance of the principal and interest in respect of our commitments for future payments to the IIA for both programs
combined totaled approximately $37.6 million. To date, we have paid the IIA in relation to our licenses agreement royalties of approximately $0.6 million.

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.

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

Under the Research Law, we are required to manufacture the majority of each of our product candidates 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 outside of Israel.
Even if we do receive approval to manufacture product candidates 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  product  candidates  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. For Israeli entities, 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, 2021, 2020
and 2019, we recorded grants totaling $0.5 million, $1.5 million and $2.7 million from the IIA, respectively. The grants represented an approximately 2%,
7% and 15%, respectively, of our gross research and development expenditures for the years ended December 31, 2021, 2020 and 2019. 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.

We  have  been  selected  for  €17.5  million  of  funding  from  the  Horizon  Europe  EIC  Accelerator  Program,  which  funding  is  subject  to  a  lengthy
process, including negotiation and finalization of documentation, prior to receipt.

On  December  20,  2021,  VBL  announced  that  it  had  been  selected  for  €17.5  million  of  blended  funding  by  the  European  Innovation  Council,  or  EIC,
Accelerator. The funding is comprised of a €2.5 million grant and an additional €15 million direct equity investment by the EIC. The funding process can
be lengthy, including establishing and arranging for implementation of the investment and finalization of documentation, and we have yet to receive either
the grant or the equity funding. The funding is also subject to meeting the specific requirements of the program and there can be no assurance that we meet
and will continue to meet these requirements in order to receive the funding.

Risks Related to the Discovery and Development of Our Product Candidates and Platform Technologies

We are highly dependent on the success of ofra-vec in oncology applications, and our platform technologies in general, and we cannot be certain
that any of them will receive regulatory approval or be commercialized. Any failure to successfully develop, obtain regulatory approval for and
commercialize ofra-vec 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 spent time, money and effort on the development of our platform technologies and product candidates, particularly ofra-vec. To date, we have not
received  regulatory  approval  for  any  of  our  product  candidates.  Positive  results  obtained  during  early  development  do  not  necessarily  mean  later
development will succeed or that regulatory approvals will be obtained.

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 Vascular Targeting System, or VTS, platform technology and its lead candidate ofra-vec;

● successfully enrolling and completing our ongoing and future trials of ofra-vec or other product candidates;

● our ability to raise additional funding sufficient to conduct future clinical trials and commercialization of our product candidates, if approved;

● demonstrating that ofra-vec or other product candidates are safe and effective at a sufficient level of statistical or clinical significance and otherwise

obtaining marketing approvals from regulatory authorities;

● operating our facility to manufacture 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, to ensure adequate supply of our product candidates for 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 payers 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 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, if approved, on a timely or profitable basis, if at all. If an issue is identified in one of
our platform technologies, it may cause us to cease development of the product candidates that utilize the underlying technology.

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.

Certain of our product candidates are based on novel adenovirus technology with which there is limited clinical or regulatory experience to date, which
makes it difficult to predict the time and cost of product candidate development and subsequently obtaining regulatory approval. Regulatory requirements
governing  virus-based  products  have  changed  frequently  and  may  continue  to  change  in  the  future.  For  example,  in  addition  to  the  submission  of  an
Investigational New Drug, or IND, application to the FDA before initiation of a clinical trial in the United States, certain human clinical trials involving
recombinant or synthetic nucleic acid molecules are subject to oversight by institutional biosafety committees, or IBCs, as set forth in the U.S. National
Institutes of Health, or NIH, Guidelines for Research Involving Recombinant or Synthetic Nucleic Acid Molecules, or NIH Guidelines. Under the NIH
Guidelines,  recombinant  and  synthetic  nucleic  acids  are  defined  as:  (i)  molecules  that  are  constructed  by  joining  nucleic  acid  molecules  and  that  can
replicate  in  a  living  cell  (i.e.,  recombinant  nucleic  acids);  (ii)  nucleic  acid  molecules  that  are  chemically  or  by  other  means  synthesized  or  amplified,
including those that are chemically or otherwise modified but can base pair with naturally occurring nucleic acid molecules (i.e., synthetic nucleic acids); or
(iii) molecules that result from the replication of those described in (i) or (ii). Specifically, under the NIH Guidelines, supervision of human gene transfer
trials includes evaluation and assessment by an IBC, a local institutional committee that reviews and oversees research utilizing recombinant or synthetic
nucleic  acid  molecules  at  that  institution.  The  IBC  assesses  the  safety  of  the  research  and  identifies  any  potential  risk  to  the  public  health  or  the
environment, and such review may result in some delay before initiation of a clinical trial. While the NIH Guidelines are not mandatory unless the research
in question is being conducted at or sponsored by institutions receiving NIH funding of recombinant or synthetic nucleic acid molecule research, many
companies and other institutions not otherwise subject to the NIH Guidelines voluntarily follow them.

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;

10

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Table of Contents 

● 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,  some  of  the  indications  we  may  develop  our  candidates  for  may  be  for  rare  disorders  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.

We plan to seek initial marketing approval in Europe and Japan, 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  a  Phase  3  clinical  trial  evaluating  ofra-vec  for  ovarian  cancer  and  are  supporting  two  clinical  trials  of  ofra-vec  for  recurrent
glioblastoma  multiforme,  or  rGBM,  and  colorectal  cancer  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, and that the trial will result in a positive outcome. Our Phase 3 clinical trial has two individual
primary endpoints, progression-free survival, or PFS, and overall survival, or OS. We cannot guarantee that successfully meeting PFS, or interim OS data,
will be sufficient to support FDA approval or that successfully meeting PFS will be indicative of OS results. We also cannot guarantee that we will receive
regulatory approval if we achieve statistical significance absent clinically meaningful benefit. 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 Institutional Review Board, or 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;

● delays in clinical trial supply, due to manufacturing delays or other issues, including as a result of FDA technical reviews (such as what occurred in

June 2021 when we had to temporarily suspend supply from our Modi’in facility for the U.S. trial sites);

● 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 ongoing investigator- sponsored trials, which are conducted by academic and other investigational third parties

and are not controlled by us, although we do contribute funding and staffing.

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 unable to compete with other approved products;

● 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 or use 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, because 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  unforeseen
adverse events that we cannot predict. 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, if at all, or could negatively impact the
market acceptance of such products, if approved.

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. The
results  of  nonclinical  and  preclinical  studies  and  clinical  trials  may  not  be  predictive  of  the  results  of  later-stage  clinical  trials,  and  interim  results  of  a
clinical trial do not necessarily predict final results. The results of preclinical studies and clinical trials in one set of patients or disease indications may not
be predictive of those obtained in another. In some instances, there can be significant variability in safety or efficacy results between different clinical trials
of  the  same  product  candidate  due  to  numerous  factors,  including  changes  in  trial  procedures  and  timing  of  such  procedures  as  set  forth  in  protocols,
differences in the size and type of the patient populations, changes in and adherence to the dosing regimen and the rate of dropout among clinical trial
participants, among other factors. Product candidates in later stages of clinical trials may fail to show the desired safety and efficacy profile despite having
progressed through nonclinical studies and initial clinical trials. For example, ofra-vec did not meet the primary endpoint in a Phase 3 trial in rGBM. We
believe that this lack of efficacy was due to a significant change in the treatment regimen between the Phase 2 and Phase 3 trials to administer Avastin in
combination with ofra-vec rather than ofra-vec monotherapy priming, and the mechanistic incompatibility of ofra-vec and Avastin, however, we cannot
conclusively confirm this hypothesis prior to generating additional clinical data. 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  or  the  EMA  may  require  us  to  conduct  additional  clinical  trials,
possibly involving a larger sample size or a different clinical trial design, particularly if the FDA or the EMA 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,
achieving statistical significance is no guarantee of approval if there is no clinically meaningful benefit.

It is also 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, or if the FDA is unable to conduct a timely inspection of our or our third party manufacturing facility. 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 ofra-vec 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 ofra-vec.

Even though we have obtained orphan drug designation for ofra-vec for treatment of ovarian cancer in Europe, and the treatment of malignant
glioma in the United States and glioma 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
defined as a patient population of fewer than 200,000 individuals annually in the United States, or a patient population of more than 200,000 in the United
States where there is no reasonable expectation that the cost of developing the product will be recovered from sales in the United States. For ofra-vec, we
have  obtained  orphan  drug  designation  from  the  FDA  for  the  treatment  of  malignant  glioma  and  from  the  European  Commission  for  the  treatment  of
ovarian cancer and glioma, and we may seek orphan drug designation for other product candidates or indications, as appropriate.

Similarly, in Europe, the European Commission, upon the recommendation of the EMA’s Committee for Orphan Medicinal Products, grants orphan drug
designation to promote the development of drugs that are intended for the diagnosis, prevention or treatment of life-threatening or chronically debilitating
conditions affecting not more than 5 in 10,000 persons in Europe and for which no satisfactory method of diagnosis, prevention, or treatment has been
authorized  (or  the  product  would  be  a  significant  benefit  to  those  affected).  Additionally,  designation  is  granted  for  drugs  intended  for  the  diagnosis,
prevention, or treatment of a life-threatening, seriously debilitating or serious and chronic condition and when, without incentives, it is unlikely that sales of
the drug in Europe would be sufficient to justify the necessary investment in developing the drug.

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.  In  addition,  a  designated  orphan  drug  may  not  receive  orphan  drug  exclusivity  if  it  is  approved  for  a  use  that  is  broader  than  the
indication for which it received orphan designation.

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.
Orphan  drug  designation  neither  shortens  the  development  time  or  regulatory  review  time  of  a  product  nor  gives  the  product  any  advantage  in  the
regulatory review or approval process. While we may seek orphan drug designation for our product candidates, we may never receive such designations.
Even if we do receive such designations, there is no guarantee that we will enjoy the benefits of those designations.

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 FDA may
also impose a REMS which could entail requirements for a medication guide, physician communication plans or additional elements to ensure safe use,
such  as  restricted  distribution  methods,  patient  registries  and  other  risk  minimization  tools.  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 sponsors and their manufacturers and manufacturing 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  other  regulatory  requirements,  such  as  product  tracking  and
tracing, 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;

● impose restrictions on the marketing or manufacturing of our 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  investigational  product  candidates.
Moreover, the product candidates derived 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 product candidates 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 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 and
indication expansion for ofra-vec with a strategic partner.

We do not have the ability to independently conduct clinical trials. We rely and expect to continue to rely on medical institutions, clinical investigators,
contract laboratories and other third parties, such as CROs, to conduct or otherwise support clinical trials for our product candidates. We may also rely on
academic and private non-academic institutions to conduct and sponsor clinical trials relating to our product candidates. We will not control the design or
conduct of the investigator-sponsored trials, and it is possible that the FDA or non-U.S. regulatory authorities will not view these investigator-sponsored
trials as providing adequate support for future clinical trials, whether controlled by us or third parties, for any one or more reasons, including elements of
the design or execution of the trials or safety concerns or other trial results. Such arrangements will likely provide us certain information rights with respect
to the investigator-sponsored trials, including access to and the ability to use and reference the data, including for our own regulatory filings, resulting from
the investigator-sponsored trials. However, we would not have control over the timing and reporting of the data from investigator-sponsored trials, and we
may not own the data from certain investigator-sponsored trials. If we are unable to confirm or replicate the results from the investigator-sponsored trials or
if negative results are obtained, we would likely be further delayed or prevented from advancing further clinical development of our product candidates.
Further, if investigators or institutions breach their obligations with respect to the clinical development of our product candidates, or if the data proves to be
inadequate compared to the first-hand knowledge we might have gained had the investigator-sponsored trials been sponsored and conducted by us, then our
ability to design and conduct any future clinical trials ourselves may be adversely affected.

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  IND  enabling  studies  and  clinical  trials  are  conducted  in
accordance with the study plan and protocols. For any violations of laws and regulations during the conduct of our clinical trials, we could be subject to
warning letters or enforcement action that may include civil penalties up to and including criminal prosecution.

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 cGMP regulations enforced by the FDA through its facilities inspection program. Information
requests from the FDA or failure to meet FDA requirements can result in delays in clinical trials, and any future commercial supply. For example, in June
2021, we voluntarily paused recruitment of patients into the OVAL trial in the United States while the FDA reviewed comparability data for new ofra-vec
batches manufactured at our Modi’in facility for clinical use in the United States and the FDA has since provided clearance for us to use batches of ofra-vec
produced in our Modi’in facility in the OVAL trial. We and our contract manufacturer for ofra-vec 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 product candidates 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 product, or revocation of a pre-existing approval.

If any manufacturer with whom we contract fails to perform its obligations, we may be forced to manufacture the materials ourselves, for which we may
not have the capabilities or resources, or enter into an agreement with a different manufacturer, which we may not be able to do on reasonable terms, if at
all. In either scenario, our clinical trials supply could be delayed significantly as we establish alternative supply sources. In some cases, the technical skills
required to manufacture our products or product candidates may be unique or proprietary to the original manufacturer and we may have difficulty, or there
may be contractual restrictions prohibiting us from, transferring such skills to a back-up or alternate supplier, or we may be unable to transfer such skills at
all. In addition, if we are required to change manufacturers for any reason, we will be required to verify that the new manufacturer maintains facilities and
procedures  that  comply  with  quality  standards  and  with  all  applicable  regulations.  We  will  also  need  to  verify,  such  as  through  a  manufacturing
comparability study, that any new manufacturing process will produce our product candidate according to the specifications previously submitted to the
FDA  or  another  regulatory  authority.  The  delays  associated  with  the  verification  of  a  new  manufacturer  could  negatively  affect  our  ability  to  develop
product candidates or commercialize our products in a timely manner or within budget. In addition, changes in manufacturers often involve changes in
manufacturing procedures and processes, which could require that we conduct bridging studies between our prior clinical supply used in our clinical trials
and  that  of  any  new  manufacturer.  We  may  be  unsuccessful  in  demonstrating  the  comparability  of  clinical  supplies  which  could  require  the  conduct  of
additional clinical trials. Additionally, if any of our product candidates receive regulatory approval and supply from a 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  comparability  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.

In addition, there are risks associated with large scale manufacturing for clinical trials or commercial scale including, among others, supplier delays, cost
overruns, potential problems with process scale-up, process reproducibility, stability issues, compliance with cGMP, lot consistency and timely availability
of raw materials. Even if we obtain marketing approval for any of our current product candidates or any future product candidates, there is no assurance
that  we  or  our  manufacturers  will  be  able  to  manufacture  the  approved  product  to  specifications  acceptable  to  the  FDA  or  other  comparable  foreign
regulatory authorities, to produce it in sufficient quantities to meet the requirements for the potential commercial launch of the product or to meet potential
future  demand.  If  we  or  our  manufacturers  are  unable  to  produce  sufficient  quantities  for  clinical  trials  or  for  commercialization,  our  development  and
commercialization efforts would be impaired, which would have an adverse effect on our business, financial condition, results of operations and growth
prospects.

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  and  potential
commercialization 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.

16

 
 
 
 
 
 
 
 
 
Table of Contents 

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 in rare diseases may be
challenging and 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 result in significant
additional costs and delay the regulatory approval process.

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 at least 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 fully support world-wide commercialization of
our product candidates. Although we intend to partially rely on third-party manufacturers for commercialization, in addition to our internal manufacturing,
we have not yet entered into agreements with such third party manufacturers. 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  company  site  in  which  we  plan  to  use  for  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  very  few  manufacturers
currently  have  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.

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.

17

 
 
 
 
 
 
 
 
 
 
 
 
Table of Contents 

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. During the COVID-19 pandemic, global
supply  chain  disruptions  have  been  seen,  particularly  with  raw  materials  and  supplies  used  in  viral  production.  For  example,  we  have  seen  significant
delays obtaining certain materials and equipment needed to manufacture our product candidates. 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 us or 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 large 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, safer, 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, ofra-vec may face competition from currently approved drugs and drug candidates under development by others to treat ovarian cancer or
rGBM. In May 2009, the FDA granted accelerated approval to bevacizumab (Avastin®), which is an angiogenesis inhibitor, to treat patients with GBM
with progressive disease following prior 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 for the
treatment  of  ovarian  cancer.  The  expansion  of  poly  adenosine  diphosphate-ribose  polymerase,  or  PARP,  inhibitors  (such  as  olaparib,  niraparib  and
veliparib) for ovarian cancer, and clinical studies evaluating the potential use of drug candidates such as checkpoint inhibitors, antibody-drug conjugates
(including mirvetuximab soravtansine), bispecific antibodies, 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 used before ofra-vec, or the segment of patient population who will seek treatment with
ofra-vec.

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.

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.

Because some of our product candidates are targeting rare diseases, loss of exclusivity or competition as described above may have a significant impact on
our business 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 payers 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 payers 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 payers 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;

● ability to adhere to the handling and storage requirements of our product candidates;

● 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 payers 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  novel  coronavirus  was  identified  and
caused, and continues to cause, massive global business interruptions. More recently, in late February 2022, Russian military forces launched significant
military  action  against  Ukraine,  and  sustained  conflict  and  disruption  in  the  region  is  likely.  The  impact  to  Ukraine,  as  well  as  actions  taken  by  other
countries,  including  new  and  stricter  sanctions  by  Canada,  the  United  Kingdom,  the  European  Union,  the  United  States  and  other  countries  and
organizations against officials, individuals, regions, and industries in Russia, Ukraine and Belarus, and each country’s potential response to such sanctions,
tensions, and military actions could have an adverse effect on our operations. 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.

Legislative and regulatory activity may exert downward pressure on potential pricing and reimbursement for any of our product candidates, if
approved, that could materially affect the opportunity to commercialize.

The United States and several other jurisdictions are considering, or have already enacted, a number of legislative and regulatory proposals to change the
healthcare system in ways that could affect our ability to sell any of our product candidates profitably, if approved. Among policy-makers and payers in the
United States and elsewhere, there is significant interest in promoting changes in healthcare systems with the stated goals of containing healthcare costs,
improving quality and/or expanding access to healthcare. In the United States, the pharmaceutical industry has been a particular focus of these efforts and
has been significantly affected by major legislative initiatives. There have been, and likely will continue to be, legislative and regulatory proposals at the
federal  and  state  levels  directed  at  broadening  the  availability  of  healthcare  and  containing  or  lowering  the  cost  of  healthcare.  We  cannot  predict  the
initiatives that may be adopted in the future.

The continuing efforts of the government, insurance companies, managed care organizations and other payers of healthcare services to contain or reduce
costs of healthcare may adversely affect:

● the demand for any of our product candidates, if approved;

● the ability to set a price that we believe is fair for any of our product candidates, if approved;

● our ability to generate revenues and achieve or maintain profitability;

● the level of taxes that we are required to pay; and

● the availability of capital.

We  expect  that  the  as  amended  by  the  Health  Care  and  Education  Reconciliation  Act  of  2010,  or,  collectively,  the  ACA,  as  well  as  other  healthcare
reform measures that may be adopted in the future, may result in more rigorous coverage criteria and in additional downward pressure on the price that
we receive for any approved product. Any reduction in reimbursement from Medicare or other government programs may result in a similar reduction in
payments from private payers. The implementation of cost containment measures or other healthcare reforms may prevent us from being able to generate
revenue, attain profitability or commercialize our product candidates.

Moreover, increasing efforts by governmental and third-party payers in the United States and abroad to cap or reduce healthcare costs may cause such
organizations  to  limit  both  coverage  and  the  level  of  reimbursement  for  newly  approved  products  and,  as  a  result,  they  may  not  cover  or  provide
adequate  payment  for  our  product  candidates.  There  has  been  increasing  legislative  and  enforcement  interest  in  the  United  States  with  respect  to
specialty  drug  pricing  practices.  Specifically,  there  have  been  several  recent  U.S.  Congressional  inquiries  and  proposed  and  enacted  federal  and  state
legislation designed to, among other things, bring more transparency to drug pricing, reduce the cost of prescription drugs under Medicare, review the
relationship between pricing and manufacturer patient programs, and reform government program reimbursement methodologies for drugs.

We expect that the healthcare reform measures that have been adopted and may be adopted in the future, may result in more rigorous coverage criteria
and in additional downward pressure on the price that we receive for any approved product and could seriously harm our future revenues. Any reduction
in reimbursement from Medicare or other government programs may result in a similar reduction in payments from private payers. The implementation
of cost containment measures or other healthcare reforms may prevent us from being able to generate revenue, attain profitability or commercialize our
products.

Our relationships with customers and third-party payers may be subject, directly or indirectly, to applicable anti-kickback laws, fraud and abuse
laws, false claims laws, health information privacy and security laws and other healthcare laws and regulations, which could expose us to criminal
sanctions, civil penalties, contractual damages, reputational harm, administrative burdens and diminished profits and future earnings.

We  are  subject  to  additional  healthcare  statutory  and  regulatory  requirements  and  enforcement  by  the  federal  government  and  the  states  and  foreign
governments in which we conduct our business. Healthcare providers, physicians and third-party payers play a primary role in the recommendation and
prescription of any of our approved drugs and drug candidates for which we obtain marketing approval. Our current and future arrangements with third-
party payers and customers may expose us to broadly applicable fraud and abuse and other healthcare laws and regulations that may constrain the business
or financial arrangements and relationships through which we market, sell and distribute any products for which we obtain marketing approval. In addition,
we  may  be  subject  to  health  information  privacy  and  security  regulation  of  the  European  Union,  the  United  States  and  other  jurisdictions  in  which  we
conduct our business. For example, the laws that may affect our ability to operate include:

● the U.S. federal Anti-Kickback Statute, which prohibits, among other things, persons from knowingly and willfully soliciting, receiving, offering or
paying remuneration, directly or indirectly, to induce, or in return for, either the referral of an individual, or the purchase or recommendation of an item
or  service  for  which  payment  may  be  made  under  a  federal  healthcare  program,  such  as  the  Medicare  and  Medicaid  programs.  In  addition,  the
government may assert that a claim including items or services resulting from a violation of the federal Anti-Kickback Statute constitutes a false or
fraudulent claim for purposes of the federal civil False Claims Act or federal civil money penalties statute (as discussed below);

● U.S. federal civil and criminal false claims laws and civil monetary penalty laws, including the federal False Claims Act, which impose criminal and
civil penalties against individuals or entities for knowingly presenting, or causing to be presented, to the federal government, including the Medicare
and Medicaid programs, claims for payment that are false or fraudulent, making a false statement to avoid, decrease or conceal an obligation to pay
money to the federal government, or knowingly concealing or knowingly and improperly avoiding or decreasing such an obligation;

● the U.S. federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, and its implementing regulations, which created new federal
criminal  statutes  that  prohibit  executing  a  scheme  to  defraud  any  healthcare  benefit  program  and  prohibit  knowingly  and  willfully  falsifying,
concealing  or  covering  up  a  material  fact  or  making  any  materially  false  statements  in  connection  with  the  delivery  of  or  payment  for  healthcare
benefits, items or services;

● HIPAA,  as  amended  by  the  Health  Information  Technology  for  Economic  and  Clinical  Health  Act  of  2009,  and  their  respective  implementing
regulations, which impose certain obligations, including mandatory contractual terms, on covered healthcare providers, health plans, and healthcare

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
clearinghouses,  as  well  as  their  business  associates,  with  respect  to  safeguarding  the  privacy,  security  and  transmission  of  individually  identifiable
health information;

● the U.S. federal Physician Payments Sunshine Act which requires certain manufacturers of drugs, devices, biologics, and medical supplies for which
payment is available under Medicare, Medicaid, or the Children’s Health Insurance Program, with specific exceptions, to report annually to the Centers
for  Medicare  &  Medicaid  Services  information  related  to  payments  or  transfers  of  value  made  to  physicians  (currently  defined to include doctors,
dentists,  optometrists,  podiatrists  and  chiropractors),  physician  assistants,  nurse  practitioners,  clinical  nurse  specialists,  certified  registered  nurse
anesthetists and teaching hospitals, as well as information regarding ownership and investment interests held by the physicians described above and
their immediate family members;

● federal  government  price  reporting  laws,  which  require  us  to  calculate  and  report  complex  pricing  metrics  in  an  accurate  and  timely  manner  to

government programs;

● federal consumer protection and unfair competition laws, which broadly regulate marketplace activities and activities that potentially harm consumers;

and

● analogous  state  and  laws  and  regulations  in  other  jurisdictions,  such  as  state  anti-kickback  and  false  claims  laws,  which  may  apply  to  sales  or
marketing  arrangements  and  claims  involving  healthcare  items  or  services  reimbursed  by  non-governmental  third-party  payers,  including  private
insurers,  and  state  and  laws  in  other  jurisdiction  governing  the  privacy  and  security  of  health  information  in  certain  circumstances,  many  of  which
differ from each other in significant ways and often are not preempted by HIPAA, thus complicating compliance efforts.

The scope and enforcement of each of these laws is uncertain and subject to rapid change in the current environment of healthcare reform. Federal and state
enforcement  bodies  have  recently  increased  their  scrutiny  of  interactions  between  healthcare  companies  and  healthcare  providers,  which  has  led  to  a
number  of  investigations,  prosecutions,  convictions  and  settlements  in  the  healthcare  industry.  Ensuring  that  our  internal  operations  and  future  business
arrangements  with  third  parties  comply  with  applicable  healthcare  laws  and  regulations  will  involve  substantial  costs.  It  is  possible  that  governmental
authorities  will  conclude  that  our  business  practices  do  not  comply  with  current  or  future  statutes,  regulations,  agency  guidance  or  case  law  involving
applicable fraud and abuse or other healthcare laws and regulations. If our operations are found to be in violation of any of the laws described above or any
other  governmental  laws  and  regulations  that  may  apply  to  us,  we  may  be  subject  to  significant  penalties,  including  administrative,  civil  and  criminal
penalties, damages, fines, disgorgement, the exclusion from participation in federal and state healthcare programs, individual imprisonment, reputational
harm, and the curtailment or restructuring of our operations, as well as additional reporting obligations and oversight if we become subject to a corporate
integrity agreement or other agreement to resolve allegations of non-compliance with these laws. Further, defending against any such actions can be costly
and time consuming, and may require significant financial and personnel resources. Therefore, even if we are successful in defending against any such
actions that may be brought against us, our business may be impaired. If any of the physicians or other providers or entities with whom we expect to do
business are found to not be in compliance with applicable laws, they may be subject to criminal, civil or administrative sanctions, including exclusions
from government funded healthcare programs and imprisonment. If any of the above occur, our ability to operate our business and our results of operations
could be adversely affected.

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 payers 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 payers. 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.

Third-party payers decide which drugs and treatments they will cover and the amount of reimbursement. Reimbursement by a third-party payer may
depend upon a number of factors, including, but not limited to, the third-party payer’s determination that use of a product is:

●

●

●

●

●

a covered benefit under its health plan;

safe, effective and medically necessary;

appropriate for the specific patient;

cost-effective; and

neither experimental nor investigational.

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 payers 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.

Obtaining coverage and reimbursement of a product from a government or other third-party payer is a time consuming and costly process that could require
us to provide to the payer supporting scientific, clinical and cost-effectiveness data for the use of our products. Even if we obtain coverage for a given
product,  if  the  resulting  reimbursement  rates  are  insufficient,  hospitals  may  not  approve  our  product  for  use  in  their  facility  or  third-party  payers  may
require  co-payments  that  patients  find  unacceptably  high.  Patients  are  unlikely  to  use  our  product  candidates  unless  coverage  is  provided,  and
reimbursement is adequate to cover a significant portion of the cost of our product candidates. Separate reimbursement for the product itself may or may
not be available. Instead, the hospital or administering physician may be reimbursed only for providing the treatment or procedure in which our product is
used. Further, from time to time, CMS revises the reimbursement systems used to reimburse health care providers, including the Medicare Physician Fee
Schedule and Outpatient Prospective Payment System, which may result in reduced Medicare payments. In some cases, private third-party payers rely on
all or portions of Medicare payment systems to determine payment rates. Changes to government healthcare programs that reduce payments under these
programs may negatively impact payments from private third-party payers and reduce the willingness of physicians to use our product candidates.

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  payers,  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 marketability of any product candidates for which we receive regulatory approval for commercial sale may suffer if government and other third-party
payers  fail  to  provide  coverage  and  adequate  reimbursement.  We  expect  downward  pressure  on  pharmaceutical  pricing  to  continue.  Further,  coverage
policies  and  third-party  reimbursement  rates  may  change  at  any  time.  Even  if  favorable  coverage  and  reimbursement  status  is  attained  for  one  or  more
products for which we receive regulatory approval, less favorable coverage policies and reimbursement rates may be implemented in the future.

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 will be limited to the specific diseases and indications for which the products have been approved by the FDA or
similar authorities in other jurisdictions. In addition, any new indication for an approved product also requires regulatory approval. If we obtain approval
for a product candidate, 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 products, if approved, 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  the  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 and greater financial resources than us. 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 external resources, and we may experience difficulties in managing this growth, which could disrupt
our operations.

As of March 1, 2022, we had 41 employees. We continue to expand our infrastructure and external resources to support the activities required to advance
our product candidates through clinical development and potential commercialization as well as operate as a public company. We expect to expand our full-
time  employee  base  and  to  hire  more  consultants  and  contractors  to  support  the  company’s  activities.  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 ongoing COVID-19 pandemic, 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 United States, European countries and Israel, where our operations are. The list of countries and regions affected by the coronavirus outbreak and new
variants are constantly changing and our clinical trial sites and third party collaborators 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 ability to complete the development of our product candidates in a
timely manner and access capital through the financial markets.

Additionally, timely enrollment in clinical trials is reliant on clinical trial sites that may be adversely affected by the COVID-19 pandemic and other global
health matters. 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;

22

 
 
 
Table of Contents 

● increased rates of patients withdrawing from our clinical trials following enrollment as a result of contracting COVID-19, being forced to quarantine or

not accepting home health visits;

● 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 ongoing 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  ongoing  COVID-19  pandemic  has  impacted  our  development  programs  to  date,  please  refer  to  the  related
section in the Overview.

The  ongoing  COVID-19  pandemic  could  also  interrupt  the  business  of  our  subcontractors,  vendors  and  external  laboratories.  For  example,  since  the
beginning of the ongoing COVID-19 pandemic, three vaccines for COVID-19 have received Emergency Use Authorization by the FDA and two of those
later received marketing approval. Additional vaccines may be authorized or approved in the future. The resultant demand for vaccines and potential for
manufacturing facilities and materials to be commandeered under the Defense Production Act of 1950, or equivalent foreign legislation, may make it more
difficult to obtain materials or manufacturing slots for the products needed for our clinical trials, which could lead to delays in these trials. For example, the
COVID-19 pandemic has, at least in part, caused supply chain disruptions which have led to significant delays receiving materials and equipment required
to  manufacture  our  product  candidates.  Continued  or  future  similar  supply  chain  disruptions  may  result  in  delays  in  our  clinical  trials  or  commercial
manufacturing.

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, the identification of new variants of the virus, and the actions to
contain the coronavirus or treat its impact, among others.

Inadequate  funding  for  the  FDA,  the  SEC  and  other  government  agencies,  including  from  government  shut  downs,  or  other  disruptions  to  these
agencies’ operations, could hinder their ability to hire and retain key leadership and other personnel, prevent new products and services from being
developed  or  commercialized  in  a  timely  manner  or  otherwise  prevent  those  agencies  from  performing  normal  business  functions  on  which  the
operation of our business may rely, which could negatively impact our business.

The ability of the FDA to review and approve new products can be affected by a variety of factors, including government budget and funding levels, ability
to hire and retain key personnel and accept the payment of user fees, and statutory, regulatory and policy changes. Average review times at the agency have
fluctuated  in  recent  years  as  a  result.  Disruptions  at  the  FDA  and  other  agencies  may  also  slow  the  time  necessary  for  new  product  candidates  to  be
reviewed and/or approved by necessary government agencies, which would adversely affect our business. In addition, government funding of the SEC and
other  government  agencies  on  which  our  operations  may  rely,  including  those  that  fund  research  and  development  activities,  is  subject  to  the  political
process, which is inherently fluid and unpredictable.

Separately, since March 2020 when foreign and domestic inspections of facilities were largely placed on hold due to the COVID-19 pandemic, the FDA
has been working to resume routine surveillance, bioresearch monitoring and pre-approval inspections on a prioritized basis. Since April 2021, the FDA
has conducted limited inspections and employed remote interactive evaluations, using risk management methods, to meet user fee commitments and goal
dates. Ongoing travel restrictions and other uncertainties continue to impact oversight operations both domestic and abroad and it is unclear when standard
operational levels will resume. The FDA is continuing to complete mission-critical work, prioritize other higher-tiered inspectional needs (e.g., for-cause
inspections), and carry out surveillance inspections using risk-based approaches for evaluating public health. Should FDA determine that an inspection is
necessary  for  approval  and  an  inspection  cannot  be  completed  during  the  review  cycle  due  to  restrictions  on  travel,  and  the  FDA  does  not  determine  a
remote interactive evaluation to be adequate, the agency has stated that it generally intends to issue, depending on the circumstances, a complete response
letter  or  defer  action  on  the  application  until  an  inspection  can  be  completed.  During  the  COVID-19  public  health  emergency,  a  number  of  companies
announced receipt of complete response letters due to the FDA’s inability to complete required inspections for their applications. Regulatory authorities
outside the U.S. may adopt similar restrictions or other policy measures in response to the ongoing COVID-19 pandemic and may experience delays in
their regulatory activities. If a prolonged government shutdown or other disruption occurs, it could significantly impact the ability of the FDA to timely
review and process our regulatory submissions, which could have a material adverse effect on our business. Future shutdowns or other disruptions could
also affect other government agencies such as the SEC, which may also impact our business by delaying review of our public filings, to the extent such
review is necessary, and our ability to access the public markets.

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;

23

 
Table of Contents 

● 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 prior Phase 3 trial of ofra-vec in rGBM and the ongoing Phase 3 trial of ofra-vec 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  that  is  currently  manufacturing  product  for  our  Phase  3  OVAL  trial  and  that  we  expect  to  use  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 may not be able to replace it at all, which would increase our reliance on third party manufacturers.
Any  new  facility  needed  to  replace  our  existing  or  future  manufacturing  facility  or  any  new  third  party  manufacturer  would  need  to  comply  with  the
necessary regulatory requirements, and be tailored to our manufacturing requirements and processes. We would need FDA authorization before using any
product candidates manufactured at a new facility or by a new manufacturer 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.

See “-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” and “-We intend to at least 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” under this Item for more information. 

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 ofra-vec, and ofra-vec 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 product candidates for our clinical trials.

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  SEC  and  the  Nasdaq  Global  Market  have  imposed  various  requirements  on  public  companies.  As  noted  herein,  it  is
expected that as a result of the composition of our board of directors, management team and current shareholder base, we will cease to be a “foreign private
issuer” on January 1, 2023 and will be required to comply with U.S. reporting requirements as well as become subject to additional obligations due to our
anticipated change in status. 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 and the transition from being a foreign private issuer 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.

Additionally, we are 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. Further, we are
now an accelerated filer based on our public float as of June 30, 2021 and must comply with Section 404(b) of the Sarbanes-Oxley Act, which requires us
to include an attestation report issued by our independent registered public accounting firm on our management’s assessment of our internal control over
financial reporting. If we identify material weaknesses in our internal control over financial reporting, if we are unable to assert that our internal control
over financial reporting is effective, or if our independent registered public accounting firm is unable to express an opinion or issues an adverse opinion in
its  attestation  as  to  the  effectiveness  of  our  internal  control  over  financial  reporting  required  by  Section  404(b),  investors  may  lose  confidence  in  the
accuracy and completeness of our financial reports and the trading price of our ordinary shares could be negatively affected. We could also become subject
to investigations by the stock exchange on which our securities are listed, the SEC or other regulatory authorities, which could require additional financial
and management resources.

Irrespective of compliance with Sections 404(a) and 404(b) of the Sarbanes-Oxley Act, any failure of our internal control could have a material adverse
effect on our stated results of operations and harm our reputation. In order to implement changes to our internal control over financial reporting triggered
by a failure of those controls, we could experience higher than anticipated operating expenses, as well as higher independent auditor fees during and after
the implementation of these changes.

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 NIS in late 2021 strengthened to
levels that were multi-year highs. 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.

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. We
have recently expanded operations into the United States and entered into U.S. employment agreements. As employment law varies from U.S. state to state,
we may not be able to enforce non-compete rights in such agreements if U.S. employees reside in states that do not recognize such rights.

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.

Ofra-vec incorporates an adenoviral vector as its delivery vehicle, which is manufactured based on rights in-licensed from Janssen Vaccines & Prevention
B.V.,  or  Janssen.  If  we  fail  to  meet  our  obligations  under  this  license  agreement,  including  various  diligence,  milestone  payment,  royalty  and  other
obligations, Janssen 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  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 because there are currently no significantly similar alternatives on the market that we would use to produce these
candidates including ofra-vec.

Table of Contents 

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 and materially affect our operations and financial condition.

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. Because 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.

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.

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 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  therewith,  in  particular,  the  inter  partes  review
proceedings. It remains to be seen what impact the Leahy-Smith Act will have on the operation of our business. However, 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 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.

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  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.

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 or funding on acceptable terms or such time as it would be required;

● 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  or  delay  in  scaling  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 the estimates, expectations, and projections of the investment community and our stockholders;

● 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;

● general economic and market conditions and overall fluctuations in the U.S. equity market;

● any identified material weakness in our internal control over financial reporting;

● changes in the Nasdaq listing of our stock;

● recommendations of equity analysts covering our stock;

● 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, 2021, to the best of our information, our executive officers, key management, directors, five percent shareholders and their affiliates
beneficially  owned  approximately  36.1%  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.

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, including pursuant to the at-the-market facility with Jefferies LLC, or the Jefferies ATM , or the
equity investment component of our European Innovation Commission award. If we sell ordinary shares, convertible securities or other equity securities in
one  or  more  transactions,  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.

We also have equity plans that provide for the grant of share options and other equity-based awards to our employees, directors and consultants, and have
issued warrants. The exercise of any of these options and warrants would result in additional share issuances and may be dilutive. As these securities are
registered, many are available for resale into the public market. Sales of a substantial number of shares of our ordinary shares by our existing stockholders
in the public market, or the perception that these sales might occur, could depress the market price of our common stock and could impair our ability to
raise capital through the sale of additional equity securities. We are unable to predict the effect that such sales may have on the prevailing market price of
our ordinary shares.

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.  Certain  milestones  we
expect  to  achieve  in  2022,  including  the  top-line  PFS  results  from  the  OVAL  Phase  3  trial,  have  the  potential  to  increase  the  volatility  of  our  ordinary
shares.  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 expectations that we are unable to meet, or cease publishing reports about us or our business.

Risks Related to Our Incorporation and Operations in Israel

We are currently 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 currently 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 currently 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,  which  we  assess  annually  on  the  last  business  day  of  our  most  recently
completed fiscal quarter. As noted elsewhere, we currently anticipate that we will lose foreign private issuer status at our next assessment and cease to be a
foreign private issuer as of January 1, 2023. Although we have elected to comply with certain U.S. regulatory provisions, our anticipated 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. Once we are no longer 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 also 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.

We expect to lose our foreign private issuer status, which will require us to comply with the Exchange Act’s domestic reporting regime and cause
us to incur significant legal, accounting and other expenses, even if we are able to qualify as a “smaller reporting company.”

We currently qualify as a foreign private issuer. As a foreign private issuer, we are permitted by the SEC to file an annual report on Form 20-F and copies
of certain home country materials on Form 6-K in lieu of filing annual, quarterly and current reports on Forms 10-K, 10-Q and 8-K. We are exempt from
SEC proxy statement requirements and certain SEC tender offer requirements and our affiliates are exempt from Section 16 of the Exchange Act.

We currently expect that due to the composition of our board of directors, our management team and our shareholder base, we will cease to be a foreign
private issuer and cease to be eligible for the foregoing exemptions and privileges effective January 1, 2023. When we cease to be a foreign private issuer,
we  will  be  required  to  comply  with  all  of  the  periodic  disclosure  and  current  reporting  requirements  of  the  Exchange  Act  applicable  to  U.S.  domestic
issuers as of January 1, 2023, which are more detailed and extensive than the requirements for foreign private issuers. We may also be required to make
changes  in  our  corporate  governance  practices  in  accordance  with  various  SEC  and  Nasdaq  rules.  Although  we  already  report  under  U.S.  GAAP  and
voluntarily publish quarterly financial information, the regulatory and compliance costs to once we are required to comply with the reporting requirements
applicable to a U.S. domestic issuer may be significantly higher than the cost we incur as a foreign private issuer even if we are able to qualify as a “smaller
reporting company.”

Table of Contents 

As a result, we expect that a loss of foreign private issuer status will increase our legal and financial compliance costs and may make some activities highly
time  consuming  and  costly.  It  will  also  impose  additional  burdens  on  holders  of  our  securities,  which  may  make  an  investment  in  our  company  less
attractive. We expect that complying with the rules and regulations applicable to United States domestic issuers may make it more difficult and expensive
for us to obtain director and officer liability insurance, and we may be required to accept reduced coverage or incur substantially higher costs to obtain
coverage. These rules and regulations could also make it more difficult for us to attract and retain qualified members of our board of directors.

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 core operations are located in the State of Israel, with a smaller operational base in the United
States. In addition, most of our key employees and officers and three 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.

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, 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, including Egypt and Syria, which border Israel. 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, 2022, we had 41 employees, 39 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 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 document 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. Most of our executive officers
and three of our directors, and the Israeli experts named in this document, 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.

Because 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.”

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,  2021  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.”

Because 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, 2020 and 2021 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.

Summary

We are a clinical stage biopharmaceutical company committed to developing next-generation, targeted medicines for difficult-to-treat medical conditions.
Using our novel platform technologies we have created a pipeline of therapeutics to uniquely address cancer and immune-inflammatory diseases with the
goal of significantly improving patient outcomes and overcoming the limitations of currently approved treatments.

Our product candidates are built off of our two platform technologies: VTS, a gene-based technology targeting newly formed blood vessels, and Monocyte
Targeting Technology, or MTT, an antibody-based technology able to specifically inhibit monocyte migration for immune-inflammatory applications.

We  are  currently  evaluating  our  lead  candidate,  ofra-vec,  in  a  Phase  3  registration-enabling  trial  in  platinum  resistant  ovarian  cancer,  for  which  we
anticipate PFS primary endpoint data in the second half of 2022. We are also supporting Phase 2 trials in rGBM and metastatic colorectal cancer, or mCRC
where  we  expect  preliminary  data  in  2022.  Our  second  program,  VB-601,  is  an  investigational  proprietary  monoclonal  antibody  that  binds  MOSPD2,
which  we  call  the  “mono-walk”,  receptor,  and  is  engineered  to  specifically  prevent  monocytes  from  exiting  the  blood  stream  and  traveling  to  inflamed
tissues, and is expected to begin a first-in-human clinical trial in the second half of 2022.

Our Platform Technologies

Vascular Targeting System

Our proprietary VTS technology is designed to enable systemic administration of our gene-based investigational candidates to either destroy or promote
angiogenic (newly formed) blood vessels, and be both tissue- and condition-specific. By harnessing nature and using our body’s molecular machinery, it
allows  for  targeted  gene  expression  in  endothelial  cells,  the  thin  layer  of  cells  that  lines  the  interior  surface  of  blood  vessels  undergoing  angiogenesis,
without detectable activation or expression in other cells, thereby limiting the potential for off-target effects.

The platform is made up of three components: a viral vector, novel promoter and therapeutic gene. The viral vector delivers the genetic code into cells. The
novel promoter imparts specificity for angiogenic cells, and the therapeutic gene executes the desired biological activity. We can use different combinations
and  modifications  of  these  components  to  custom  tailor  the  attributes  of  a  VTS-based  candidate  to  enhance  its  profile  for  a  specific  indication.  We  are
currently developing the VTS technology for oncology applications.

Monocyte Targeting Technology

We have also developed a second platform technology, MTT, based on the internal discovery of a novel target, MOSPD2. This novel target, which we call
the  “mono-walk”  receptor,  is  selectively  expressed  on  the  surface  of  monocytes  and  controls  their  ability  to  migrate  (or  “walk”  to)  inflamed  tissues.
Monocytes are an important cell implicated in the chronicity of disease in inflammatory indications and previous attempts by others to specifically target
this cell type and prevent its migration to sites of inflammation have been unsuccessful. We believe that our approach can address this gap in being able to
optimally address chronic inflammation and we are utilizing antibody technology to specifically inhibit this target with high potency.

Product Pipeline

Utilizing  our  platform  technologies,  we  have  created  a  pipeline  of  novel  and  differentiated  programs  addressing  difficult  to  treat  oncology  and
inflammatory applications:

Ofra-vec - Lead VTS Candidate

Our  lead  product  candidate  utilizing  the  VTS  platform  is  ofra-vec  (also  known  as  VB-111),  which  is  currently  being  evaluated  in  the  OVAL  Phase  3
registration-enabling  clinical  trial  in  platinum  resistant  ovarian  cancer  (NCT03398655)  and  Phase  2  trials  in  rGBM  (NCT04406272)  and  mCRC
(NCT04166383). Ofra-vec’s mechanism of action is designed to combine the blockade of tumor microvasculature (the blood vessels required for tumor
growth)  with  immune  recruitment  resulting  in  an  anti-tumor  immune  response  and  a  highly  differentiated  potential  treatment  for  solid  tumors.  As  an
investigational drug engineered to work through the body’s molecular machinery, ofra-vec is designed to be activated specifically when and where it is
needed. To date, over 300 patients have been dosed with ofra-vec in completed clinical trials.

Ofra-vec is a custom designed therapeutic comprised of several components and characteristics. Each individual component brings its own unique potential
advantages as it relates to difficult to treat solid tumors:

1. Viral vector (Adenovirus Type 5) – Non-integrating, and non-replicating modified virus designed to deliver the gene construct to target cells and
create a localized immune response in the tumor microenvironment. Unlike challenges seen with other approved and investigational therapeutics
using an adeno-associated virus, our adenovirus can be re-dosed chronically.

2. Promoter (PPE 1-3x) - Promoter designed to impart specificity for angiogenic endothelial cells and  engineered to contain the expression of the

therapeutic gene and anti-angiogenic effect to the tumor microvasculature without affecting healthy vasculature or other tissues.

3. Therapeutic  gene  -  Chimeric  pro-apoptotic  death  receptor  comprised  of  TNFR1  (extracellular  part)  and  FAS  (intracellular  part)  (TNF-Induced
death receptor). This genetic sequence is designed to take advantage of high tumor necrosis factor TNF-alpha levels in tumors to enhance activity.
Once the promoter expresses the gene in the target cells and the chimeric TNF-Induced death receptor is engaged in the tumor microenvironment,
it  initiates  a  self-death  process  in  the  tumor  microvasculature  (blood  vessels),  potentially  leading  to  vascular  disruption,  tumor  starvation  and
immune recruitment.

We believe these three components which comprise ofra-vec result in a unique and highly differentiated dual mechanism of action:

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
37

 
Table of Contents 

Unlike anti-vascular endothelial growth factor, or anti-VEGF agents (such as Avastin/ bevacizumab) or tyrosine-kinase inhibitors, or TKIs, ofra-vec does
not aim to block a specific pro-angiogenic pathway; instead, it is designed to use our proprietary angiogenesis-specific promoter to specifically induce cell
death  in  angiogenic  endothelial  cells  in  the  tumor  microenvironment.  This  mechanism  has  the  potential  to  retain  activity  regardless  of  baseline  tumor
mutations or the identity of the pro-angiogenic factors secreted by the tumor and has demonstrated clinical activity even after failure of prior treatment with
other anti-angiogenic agents. Nevertheless, as ofra-vec expression is induced by VEGF, it should not be co-administrated with anti-VEGF agents such as
Avastin.

Overview of Ofra-vec Clinical Programs

Ofra-vec’s dual mechanism of action targeting the vasculature and recruiting the immune system into tumors has the potential to treat a broad range of solid
tumors without relying on specific genetic drivers or receptors to enhance and enrich its activity. Most solid tumors create vasculature to support growth
and cloak themselves from the immune system, both of which we believe ofra-vec may be able to address and thereby provide a more effective therapeutic
solution and be potentially applicable to a broader patient population than current therapies.

We are evaluating ofra-vec in multiple clinical trials including the ongoing Phase 3 registration-enabling OVAL trial in platinum resistant ovarian cancer,
and have seen encouraging data from previous Phase 2 oncology trials demonstrating a dose response and the potential to increase survival, particularly in
patients  with  limited  treatment  options  and  poor  prognosis.  In  our  clinical  trials  to  date,  ofra-vec  was  generally  well-tolerated,  and  the  most  common
adverse event was transient mild-moderate fever. We have received orphan drug designation for ofra-vec for the treatment of malignant glioma by the FDA
and for the treatment of ovarian cancer and the treatment of glioma by the European Commission. We have also obtained fast track designation for ofra-vec
in  the  United  States  for  prolongation  of  survival  in  patients  with  glioblastoma  that  has  recurred  following  treatment  with  standard  chemotherapy  and
radiation.  We  have  an  open  IND  for  ofra-vec  with  the  Office  of  Tissues  and  Advanced  Therapies  within  FDA’s  Center  for  Biologics  Evaluation  and
Research.

Ofra-vec Clinical Program in Ovarian Cancer

Ovarian  cancer  is  the  leading  cause  of  gynecologic  cancer  death  in  the  United  States  affecting  approximately  21,400  women  annually.  In  patients  with
platinum-resistant disease, the addition of the anti-angiogenic agent Avastin to chemotherapy has resulted in significantly improved PFS and response rates.
However, the addition of Avastin did not result in a significant improvement of OS and the overall outcomes and prognosis for these patients remains poor.
Other approved agents such as PARP inhibitors are being used in this indication but their utility is somewhat limited by genetic factors and so far they have
failed to demonstrate an increase in survival. Given the limitations of current 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.  We  believe  that  ofra-vec’s  unique  dual  mechanism  of
action  specifically  targeting  the  tumor  vasculature  and  immune  recruitment  has  the  potential  to  improve  outcomes  and  we  are  actively  pursuing  this
application.

A Phase 1/2 study of ofra-vec in recurrent platinum-resistant ovarian cancer was initially conducted and final results were published in a peer-reviewed
publication (Arend et al., Gynecol Oncol. 2020). The data demonstrated a median OS of 498 days in the ofra-vec therapeutic-dose arm, versus 172.5 days
in the low-dose arm (p=0.03). Of the evaluable patients treated with the therapeutic dose of ofra-vec, 58% had a Gynecologic Cancer Intergroup, or GCIG,
CA-125 response. Ofra-vec 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 ofra-vec therapeutic-dose arm
(808 vs. 351 days; p=0.067) implicating CA-125 as a potentially valuable biomarker for response with ofra-vec. An immunotherapeutic effect was also
observed in biopsies taken from patients. In addition, hematoxylin and eosin and immunohistochemistry staining showed regions of apoptotic cancer cells
and infiltration of cytotoxic CD8 T-cells following treatment with ofra-vec.

After an end-of-Phase 2 meeting with the FDA to discuss the clinical path of ofra-vec in ovarian cancer, we aligned with the FDA on our clinical plan to
proceed to a Phase 3 registration-enabling trial of ofra-vec in platinum-resistant patients and initiated the OVAL Phase 3 trial. We have since completed
enrollment for this global Phase 3 randomized, multi-center, placebo-controlled registration-enabling clinical trial evaluating the combination of ofra-vec
and paclitaxel versus placebo and paclitaxel, in patients with platinum-resistant ovarian cancer. A total of 409 patients have been enrolled in the OVAL trial
at approximately 75 clinical sites in the United States, Europe, Israel and Japan, with the majority having previously failed Avastin and/or PARP inhibitor
therapies. Patients were randomized 1:1 to ofra-vec (1x1013 viral particles, or VPs, once every eight weeks) in combination with chemotherapy (80mg/m2
paclitaxel  once  weekly),  or  to  placebo  with  chemotherapy.  The  study  includes  two  individual  primary  endpoints,  PFS  and  OS.  Based  on  regulatory
guidance, we believe successfully meeting either primary endpoint may be sufficient to support a BLA submission. The OVAL trial is being conducted in
collaboration with the GOG Foundation, Inc., a leading organization for research excellence in the field of gynecologic malignancies.

We conducted the first pre-planned interim analysis of the OVAL trial after the first 60 enrolled subjects were evaluable for CA-125 response, an important
biomarker of disease in ovarian cancer. The interim analysis was utilized to analyze futility and confirm the initial activity of ofra-vec in the OVAL trial.
The independent Data Safety Monitoring Committee, or DSMC, reviewed unblinded data and assessed CA-125 response, measured according to the GCIG
criteria,  and  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 ofra-vec treatment arm, and recommended that the study continue as planned. The cumulative CA-125 response rate in the first 60
randomized evaluable patients was 53%. Assuming a balanced randomization, the blinded CA-125 response rate in the treatment arm (ofra-vec in addition
to weekly paclitaxel) was estimated to be 58%. Ofra-vec was well tolerated and the most common adverse event was transient mild-moderate fever. Results
of the interim analysis were published in a peer-reviewed publication (Arend et al., Gynecol Oncol. 2021). The response rate was markedly higher than
what would be expected based on the weekly paclitaxel control arm performance in the historical Avastin registration study (AURELIA Study).

A second pre-planned interim analysis in the OVAL trial was conducted and the DSMC reviewed unblinded OS data from the first 100 enrolled subjects
with a follow-up of at least three months. The committee also looked at the CA-125 response rate and safety information. The DSMC recommended that
the study continue as planned. Additional DSMC meetings have been conducted in 2021 and 2022, after the randomization of 200, 300, and 370 patients,
respectively,  and  the  committee  found  no  safety  issues  with  the  trial  and  recommended  its  continuation  as  planned.  We  expect  to  read  out  topline  PFS
primary endpoint results in the second half of 2022 and OS primary endpoint data in 2023.

Ofra-vec Clinical Program in rGBM

Glioblastoma,  or  GBM,  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 GBM, or rGBM, treatment
consists of both symptomatic and palliative therapies. However, with currently available therapies, glioblastoma typically remains fatal within a very short
period.

In  a  Phase  2  study  for  rGBM,  patients  who  were  primed  with  ofra-vec  monotherapy  that  was  continued  after  progression  with  the  addition  of  Avastin
showed a significantly longer OS (414 vs 223 days; HR 0.48; p=0.043) and PFS advantage (90 vs 60 days; HR 0.36; p=0.032) compared to a cohort of
patients that had limited exposure to ofra-vec (monotherapy until progression). Full study results were published in a peer reviewed publication (Brenner et
al., Neuro Oncol. 2019). Objective radiographic responses were seen during the ofra-vec monotherapy phase and responders exhibited specific imaging
characteristics related to ofra-vec’s mechanism of action. A survival advantage was also seen in comparison to historic controls, with the percentage of
patients living more than one year almost doubling from 24% to 57%.

We conducted the Phase 3 GLOBE study in rGBM comparing upfront concomitant administration of ofra-vec, without priming, and Avastin to Avastin
monotherapy. The treatment did not improve OS and PFS outcomes in rGBM, which conflicted with the results seen in our Phase 2 study where an ofra-
vec monotherapy priming regimen was used. The full study results were published in a peer-reviewed publication (Cloughesy et al. Neuro Oncol. 2019).
We,  and  the  paper’s  authors,  attribute  the  contradictory  outcomes  between  the  Phase  2  and  Phase  3  trials  as  being  related  to  the  lack  of  ofra-vec
monotherapy  priming  in  the  GLOBE  study,  providing  clinical,  mechanistic  and  radiographic  support  for  this  hypothesis.  In-vivo  preclinical  data
demonstrate that Avastin appears to neutralize the effect of ofra-vec by inactivating the angiogenic process that ofra-vec depends on.

A new Phase 2 clinical trial investigating ofra-vec for the treatment of rGBM has since been initiated. The Phase 2 trial, sponsored by Dana-Farber Cancer
Institute in collaboration with a group of top neuro-oncology medical centers in the United States, is investigating neo-adjuvant and adjuvant treatment
with  ofra-vec  in  rGBM  patients  undergoing  a  second  surgery  and  looks  to  replicate  the  Phase  2  results  in  rGBM,  utilizing  the  ofra-vec  monotherapy
priming regimen that was not used in the Phase 3 GLOBE study. Enrollment in this study is ongoing and we expect preliminary data from this study in
2022. We do not believe that the results and confounding factors from the GLOBE study will necessarily have implications on the prospects for ofra-vec in
other regimens or tumor types.

Ofra-vec Program in Colorectal Cancer

Ofra-vec is also being evaluated in a Phase 2 clinical trial in combination with Opdivo (nivolumab), an immune checkpoint inhibitor, for the treatment of
mCRC, under a cooperative research and development agreement with the U.S. National Cancer Institute, or NCI. NCI serves as the sponsor for this trial.
The open label exploratory Phase 2 trial will investigate if priming with ofra-vec can recruit immune cells into the tumor and turn the colorectal tumors
from being immunologically “cold” to “hot.” The purpose of the study is to determine whether the immune recruitment seen in other organ tumors from
previous ofra-vec clinical trials can be replicated in the gut immune system which is in continuous contact with viruses, bacteria and foreign proteins and
may behave differently than the rest of the body. Preliminary data from this trial are expected in 2022 and will determine whether we should further explore
this indication.

Ofra-vec Program in Thyroid Cancer

We  conducted  an  exploratory  Phase  2  clinical  trial  to  evaluate  the  safety  and  efficacy  of  ofra-vec  in  advanced  thyroid  cancer.  Thyroid  cancer  affects
approximately 44,000 newly diagnosed people each year in the United States. Most cases can be treated by surgery and radioactive iodine. If radioactive
iodine  is  ineffective,  other  treatments  are  prescribed,  such  as  TKIs  and  systemic  chemotherapy.  However,  if  such  treatments  are  unsuccessful,  the
therapeutic options for patients are currently very limited. This subset of patients has a significant unmet need for novel therapeutic options. The estimated
number of U.S. deaths of thyroid cancer in 2021 was 2,200.

We conducted a Phase 2 open-label, dose-escalating trial which 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 ofra-vec at a sub-therapeutic dose of 3X10e12
VP. The second cohort included seventeen patients, who received ofra-vec at a therapeutic dose of 10e13 VP every two months until disease progression.
One patient proceeded from a single low dose to later receive multiple high doses at progression and was included in both groups (for PFS analysis only).
The primary endpoint of the trial was defined as 6-month PFS. 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,  demonstrating  a  dose  response.  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 OS benefit was seen with a tail of more than
40% at 3.7 years for the therapeutic-dose cohort (median OS of 684 days). This is similar to historical data for pazopanib (Votrient), a TKI; however, most
patients in the Phase 2 trial had tumors that previously had progressed on pazopanib or other kinase inhibitors.

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

Ofra-Vec in Other Solid Tumor Indications

We believe ofra-vec has potential to treat a wide range of solid tumors provided they contain either a vascular component, a lack of or minimal immune
infiltration, or both. In addition to the encouraging data we have observed in our Phase 2 studies, we also conducted a Phase 1 “all comers” trial involving
patients with multiple types of advanced metastatic cancer types, including medullary thyroid cancer, neuroendocrine cancer, renal cell carcinoma and lung
cancer which showed a dose-dependent extension in median OS. We believe this Phase 1 trial provides a road map for potential indication expansion in
new oncology indications.

Ofra-vec Partnership in Japan

In  November  2017,  we  signed  an  exclusive  license  agreement  with  NanoCarrier  Co.,  Ltd.  (TSE  Mothers:4571),  or  NanoCarrier,  for  the  development,
commercialization,  and  supply  of  ofra-vec  in  Japan.  We  retained  rights  to  ofra-vec  in  the  rest  of  the  world.  Under  terms  of  the  agreement,  we  granted
NanoCarrier  an  exclusive  license  to  develop  and  commercialize  ofra-vec  in  Japan  for  all  indications.  We  will  supply  NanoCarrier  with  ofra-vec,  and
NanoCarrier  will  be  responsible  for  all  regulatory  and  other  clinical  activities  necessary  for  commercialization  in  Japan.  Under  the  agreement,  we  are
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.

VB-601 Program- Lead MTT Candidate

Our lead MTT candidate, VB-601, is an investigational proprietary monoclonal antibody that binds the MOSPD2 receptor, which we call the “mono-walk”
receptor, and is engineered to specifically prevent monocytes from exiting the blood stream and traveling to inflamed tissues. Monocytes are one of the key
cells  types  in  inflammation  and  particularly  implicated  in  being  responsible  for  the  chronicity  of  disease.  VB-601  is  designed  to  offer  a  novel  and
differentiated approach in the landscape of current anti-inflammatory agents, most of which target pro-inflammatory molecules and work through T and B
lymphocytes but are not targeted to the monocyte cells.

We  have  conducted  various  ex-vivo  and  in-vivo  pharmacology  studies  that  demonstrate  VB-601’s  activity  against  a  broad  range  of  prevalent  chronic
inflammatory indications:

Based on our preclinical in-vivo and human ex-vivo data, we believe VB-601 has potential utility in a wide range of immune-inflammatory diseases, such
as multiple sclerosis (relapsing-remitting (RRMS) and progressive (PMS), rheumatoid arthritis (RA), psoriatic arthritis (PsA), non-alcoholic steatohepatitis,
inflammatory bowel disease (including Crohn’s disease (CD) and ulcerative colitis (UC)) and other immune-inflammatory diseases. We had a successful
pre-IND meeting with the FDA regarding our development plan and have since completed IND-enabling toxicology studies that demonstrated a favorable
tolerability profile that supports moving VB-601 into the clinic. We are conducting a cGMP manufacturing run of VB-601 and expect to initiate a first in
human clinical trial in the second half of 2022.

Our Strategy

Our goal is to provide safe, effective and life-improving medicines to people living with cancer and immune-inflammatory diseases. We intend to achieve
this goal by pursuing the following strategies:

● Pursue regulatory approval for our lead oncology drug candidate, ofra-vec

We believe ofra-vec has the potential for applications in various solid tumors. Currently, our focus is on the development of ofra-vec for platinum-resistant
ovarian  cancer.  We  recently  completed  enrollment  in  the  OVAL  Phase  3  registration-enabling  trial  and  expect  the  topline  readout  of  the  PFS  primary
endpoint in the second half of 2022. If positive, we believe OVAL has the potential to support BLA submission, which we expect to file in the first half of
2023.

Ofra-vec is also being studied in Phase 2 clinical trials in rGBM and mCRC, with preliminary data expected in 2022. We also conducted a Phase 2 clinical
trial of ofra-vec in thyroid cancer, with encouraging results. We intend to advance ofra-vec in additional cancer indications, either independently or through
investigator-sponsored studies or strategic collaborations.

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

products, if approved

We will evaluate opportunities to selectively form collaborative alliances for our assets to expand our capabilities and accelerate their development and
commercialization. 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 ofra-vec

We have an in-house gene therapy manufacturing plant in Modi’in, Israel. Our facility was certified by a European Union, or EU, Qualified Person, or QP,
as being in compliance with EU Good Manufacturing Practices, or GMP. The facility is currently being used to manufacture product for our Phase 3 OVAL
trial. We believe this plant can be the first commercial facility for production of ofra-vec if we receive regulatory approval. We intend to bring on at least
one additional manufacturing site to support long term scale up and label expansion activities for ofra-vec.

Governmental Regulation

The FDA and other regulatory authorities at federal, state and local levels, as well as in foreign countries, extensively regulate, among other things, the
research, development, testing, manufacture, quality control, import, export, safety, effectiveness, labeling, packaging, storage, distribution, recordkeeping,
approval,  advertising,  promotion,  marketing,  post-approval  monitoring  and  post-approval  reporting  of  drugs  and  biologics.  We,  along  with  our  vendors,
CROs, clinical investigators and contract development and manufacturing organizations, or CDMOs, will be required to navigate the various preclinical,
clinical, manufacturing and commercial approval requirements of the governing regulatory agencies of the countries in which we wish to conduct studies or
seek approval of our product candidates. The process of obtaining regulatory approvals of drugs and biologics and ensuring subsequent compliance with
appropriate federal, state, local and foreign statutes and regulations requires the expenditure of substantial time and financial resources.

In the United States, the FDA regulates drug products under the Federal Food, Drug, and Cosmetic Act, or FD&C Act, and biologics under the FD&C Act
and the Public Health Service Act, or PHSA, as amended, and their implementing regulations. Both drugs and biologics are also subject to other federal,
state and local statutes and regulations. If we fail to comply with applicable FDA or other requirements at any time with respect to product development,
clinical  testing,  approval  or  any  other  regulatory  requirements  relating  to  product  manufacture,  processing,  handling,  storage,  quality  control,  safety,
marketing, advertising, promotion, packaging, labeling, export, import, distribution, or sale, we may become subject to administrative or judicial sanctions
or  other  legal  consequences.  These  sanctions  or  consequences  could  include,  among  other  things,  the  FDA’s  refusal  to  approve  pending  applications,
issuance of clinical holds for ongoing studies, suspension or revocation of approved applications, warning or untitled letters, product withdrawals or recalls,
product  seizures,  relabeling  or  repackaging,  total  or  partial  suspensions  of  manufacturing  or  distribution,  injunctions,  fines,  civil  penalties  or  criminal
prosecution.

Our  product  candidates  must  be  approved  for  therapeutic  indications  by  the  FDA  before  they  may  be  marketed  in  the  United  States.  For  drug  product
candidates regulated under the FD&C Act, FDA must approve an NDA. For biologic product candidates regulated under the FD&C Act and PHSA, FDA
must approve a BLA. The process is similar and generally involves the following:

● completion  of  extensive  preclinical  studies  in  accordance  with  applicable  regulations,  including  studies  conducted  in  accordance  with  good

laboratory practice, or GLP, requirements;

● completion of the manufacture, under cGMP conditions, of the drug substance and drug product that the sponsor intends to use in human clinical

trials along with required analytical and stability testing;

● submission to the FDA of an IND which must become effective before clinical trials may begin and must be updated annually and when certain

changes are made;

● approval by an institutional review board (IRB or independent ethics committee at each clinical trial site before each trial may be initiated;

● performance  of  adequate  and  well-controlled  clinical  trials  in  accordance  with  applicable  IND  regulations,  good  clinical  practice,  or  GCP,
requirements  and  other  clinical  trial-related  regulations  to  establish  the  safety  and  efficacy  of  the  investigational  product  for  each  proposed
indication;

● preparation and submission to the FDA of an NDA or BLA;

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

● satisfactory completion of one or more FDA pre-approval or pre-license inspections of the manufacturing facility or facilities where the product
will be produced to assess compliance with cGMP requirements to assure that the facilities, methods and controls are adequate to preserve the
drug or biological product’s identity, strength, quality and purity;

● satisfactory completion of FDA audit of the clinical trial sites that generated the data in support of the NDA or BLA;

● payment of user fees for FDA review of the NDA or BLA; and

● FDA review and approval of the NDA or BLA, including, where applicable, consideration of the views of any FDA advisory committee, prior to

any commercial marketing or sale of the product in the United States.

Preclinical Studies and Clinical Trials for Drugs and Biologics

Before  testing  any  drug  or  biologic  in  humans,  the  product  candidate  must  undergo  rigorous  preclinical  testing.  Preclinical  studies  include  laboratory
evaluations of product chemistry, formulation and stability, as well as in vitro and animal studies to assess safety and in some cases to establish the rationale
for  therapeutic  use.  The  conduct  of  preclinical  studies  is  subject  to  federal  and  state  regulation  and  requirements,  including  GLP  requirements  for
safety/toxicology studies. The results of the preclinical studies, together with manufacturing information and analytical data, must be submitted to the FDA
as part of an IND.

An IND is a request for authorization from the FDA to administer an investigational product to humans and must become effective before clinical trials
may begin. The central focus of an IND submission is on the general investigational plan and the protocol(s) for clinical studies. The IND also includes the
results  of  animal  and  in  vitro  studies  assessing  the  toxicology,  pharmacokinetics,  pharmacology,  and  pharmacodynamic  characteristics  of  the  product;
chemistry, manufacturing, and controls, or CMC, information; and any available human data or literature to support the use of the investigational product.
Some long-term preclinical testing may continue after the IND is submitted. The IND automatically becomes effective 30 days after receipt by the FDA,
unless the FDA, within the 30-day time period, raises concerns or questions about the conduct of the clinical trial, including concerns that human research
subjects will be exposed to unreasonable health risks, and imposes a full or partial clinical hold. FDA must notify the sponsor of the grounds for the hold
and any identified deficiencies must be resolved before the clinical trial can begin. Submission of an IND may result in the FDA not allowing clinical trials
to commence or not allowing clinical trials to commence on the terms originally specified in the IND. A clinical hold can also be imposed once a trial has
already begun, thereby halting the trial until the deficiencies articulated by FDA are corrected.

In  addition  to  the  submission  of  an  IND  to  the  FDA  before  initiation  of  a  clinical  trial  in  the  United  States,  certain  human  clinical  trials  involving
recombinant or synthetic nucleic acid molecules are subject to oversight of IBC as set forth in the NIH Guidelines. Under the NIH Guidelines, recombinant
and synthetic nucleic acids are defined as: (i) molecules that are constructed by joining nucleic acid molecules and that can replicate in a living cell (i.e.,
recombinant nucleic acids); (ii) nucleic acid molecules that are chemically or by other means synthesized or amplified, including those that are chemically
or otherwise modified but can base pair with naturally occurring nucleic acid molecules (i.e., synthetic nucleic acids); or (iii) molecules that result from the
replication  of  those  described  in  (i)  or  (ii).  Specifically,  under  the  NIH  Guidelines,  supervision  of  human  gene  transfer  trials  includes  evaluation  and
assessment by an IBC, a local institutional committee that reviews and oversees research utilizing recombinant or synthetic nucleic acid molecules at that
institution. The IBC assesses the safety of the research and identifies any potential risk to public health or the environment, and such review may result in
some  delay  before  initiation  of  a  clinical  trial.  While  the  NIH  Guidelines  are  not  mandatory  unless  the  research  in  question  is  being  conducted  at  or
sponsored by institutions receiving NIH funding of recombinant or synthetic nucleic acid molecule research, many companies and other institutions not
otherwise subject to the NIH Guidelines voluntarily follow them.

The clinical stage of development involves the administration of the product candidate to healthy volunteers or patients under the supervision of qualified
investigators, who generally are physicians not employed by or under the trial sponsor’s control, in accordance with GCP requirements, which include the
requirements  that  all  research  subjects  provide  their  informed  consent  for  their  participation  in  any  clinical  trial.  Clinical  trials  are  conducted  under
protocols detailing, among other things, the objectives of the clinical trial, dosing procedures, subject selection and exclusion criteria and the parameters
and criteria to be used in monitoring safety and evaluating effectiveness. Each protocol, and any subsequent amendments to the protocol, must be submitted
to the FDA as part of the IND. Furthermore, each clinical trial must be reviewed and approved by an IRB for each institution at which the clinical trial will
be conducted to ensure that the risks to individuals participating in the clinical trials are minimized and are reasonable compared to the anticipated benefits.
The IRB also approves the informed consent form that must be provided to each clinical trial subject or his or her legal representative and must monitor the
clinical trial until completed. The FDA, the IRB, or the sponsor may suspend or discontinue a clinical trial at any time on various grounds, including a
finding  that  the  subjects  are  being  exposed  to  an  unacceptable  health  risk.  Additionally,  some  clinical  trials  are  overseen  by  an  independent  group  of
qualified experts organized by the clinical trial sponsor, known as a DSMC. This group provides authorization for whether or not a trial may move forward
at  designated  intervals  based  on  access  to  certain  data  from  the  trial.  There  also  are  requirements  governing  the  reporting  of  ongoing  clinical  trials  and
completed clinical trials to public registries. Information about clinical trials, including results for clinical trials other than Phase 1 investigations, must be
submitted within specific timeframes for publication on www.ClinicalTrials.gov, a clinical trials database maintained by the National Institutes of Health.

A sponsor who wishes to conduct a clinical trial outside of the United States may, but need not, obtain FDA authorization to conduct the clinical trial under
an IND. If a foreign clinical trial is not conducted under an IND, FDA will nevertheless accept the results of the study in support of an NDA if the study
was conducted in accordance with GCP requirements, and the FDA is able to validate the data through an onsite inspection if deemed necessary.

Clinical  trials  to  evaluate  therapeutic  indications  to  support  NDAs  or  BLAs  for  marketing  approval  are  typically  conducted  in  three  sequential  phases,
which may overlap.

● Phase 1—Phase 1 clinical trials involve initial introduction of the investigational product in a limited population of healthy human volunteers or
patients  with  the  target  disease  or  condition.  These  studies  are  typically  designed  to  test  the  safety,  dosage  tolerance,  absorption,  metabolism,
distribution and excretion of the investigational product in humans, the side effects associated with increasing doses, and, if possible, to gain early
evidence of effectiveness.

● Phase 2—Phase  2  clinical  trials  typically  involve  administration  of  the  investigational  product  to  a  limited  patient  population  with  a  specified
disease  or  condition  to  evaluate  the  drug’s  potential  efficacy,  to  determine  the  optimal  dosages  and  dosing  schedule  and  to  identify  possible
adverse side effects and safety risks.

● Phase  3—Phase  3  clinical  trials  typically  involve  administration  of  the  investigational  product  to  an  expanded  patient  population  to  further
evaluate dosage, to provide statistically significant evidence of clinical efficacy and to further test for safety, generally at multiple geographically
dispersed clinical trial sites. These clinical trials are intended to establish the overall risk/benefit ratio of the investigational product and to provide
an adequate basis for product approval and physician labeling. Generally, two adequate and well-controlled Phase 3 trials are required by the FDA
for approval of an NDA or BLA.

Post-approval trials, sometimes referred to as Phase 4 clinical trials or post-marketing studies, may be conducted after initial marketing approval. These
trials are used to gain additional experience from the treatment of patients in the intended therapeutic indication and are commonly intended to generate
additional safety data regarding use of the product in a clinical setting. In certain instances, the FDA may mandate the performance of Phase 4 clinical trials
as a condition of NDA or BLA approval.

Progress reports detailing the results of the clinical trials, among other information, must be submitted at least annually to the FDA. Written IND safety
reports must be submitted to the FDA and the investigators fifteen days after the trial sponsor determines the information qualifies for reporting for serious
and unexpected suspected adverse events, findings from other studies or animal or in vitro testing that suggest a significant risk for human volunteers and
any clinically important increase in the rate of a serious suspected adverse reaction over that listed in the protocol or investigator brochure. The sponsor
must also notify the FDA of any unexpected fatal or life-threatening suspected adverse reaction as soon as possible but in no case later than seven calendar
days after the sponsor’s initial receipt of the information.

Concurrent with clinical trials, companies usually complete additional animal studies and must also develop additional information about the chemistry and
physical characteristics of the product candidate and finalize a process for manufacturing the drug product in commercial quantities in accordance with
cGMP  requirements.  The  manufacturing  process  must  be  capable  of  consistently  producing  quality  batches  of  the  product  candidate  and  manufacturers
must  develop,  among  other  things,  methods  for  testing  the  identity,  strength,  quality  and  purity  of  the  final  drug  product.  Additionally,  appropriate
packaging must be selected and tested, and stability studies must be conducted to demonstrate that the product candidate does not undergo unacceptable
deterioration over its shelf life.

U.S. Marketing Approval for Drugs and Biologics

Assuming successful completion of the required clinical testing, the results of the preclinical studies and clinical trials, together with detailed information
relating to the product’s CMC and proposed labeling, among other things, are submitted to the FDA as part of an NDA or BLA. An NDA is a request for
approval to market a new drug for one or more specified indications and must contain proof of the drug’s safety and efficacy for the requested indications.
A BLA is a request for approval to market a new biologic for one or more specified indications and must contain proof of the biologic’s safety, purity and
potency  for  the  requested  indications.  The  marketing  application  is  required  to  include  both  negative  and  ambiguous  results  of  preclinical  studies  and
clinical trials, as well as positive findings, together with detailed information relating to the product’s CMC, and proposed labeling, among other things.
Data may come from company-sponsored clinical trials intended to test the safety and efficacy of a product’s use or from a number of alternative sources,
including studies initiated by investigators. To support marketing approval, the data submitted must be sufficient in quality and quantity to establish the
safety and efficacy of the investigational drug, or the safety, purity and potency of the investigational biologic, to the satisfaction of the FDA. FDA must
approve an NDA or BLA before a drug or biologic may be marketed in the United States.

The FDA reviews all submitted NDAs and BLAs to ensure they are sufficiently complete to permit substantive review before it accepts them for filing and
may request additional information rather than accepting the NDA or BLA for filing. The FDA must make a decision on accepting an NDA or BLA for
filing within 60 days of receipt, and such decision could include a refusal to file by the FDA. Once the submission is accepted for filing, the FDA begins an
in-depth substantive review of the NDA or BLA. The FDA reviews an NDA or BLA to determine, among other things, whether the product is safe and
effective for the indications sought and whether the facility in which it is manufactured, processed, packaged or held meets standards designed, including
cGMP requirements, designed to assure and preserve the product’s continued identity, strength, quality and purity. Under the goals and polices agreed to by
the FDA under the Prescription Drug User Fee Act, or PDUFA, the FDA targets ten months, from the filing date, in which to complete its initial review of a
new molecular entity NDA or BLA and respond to the applicant, and six months from the filing date of a new molecular entity NDA or BLA for priority
review. The FDA does not always meet its PDUFA goal dates for standard or priority NDAs or BLAs, and the review process is often extended by FDA
requests for additional information or clarification.

Further,  under  PDUFA,  as  amended,  each  NDA  or  BLA  must  be  accompanied  by  a  substantial  user  fee.  The  FDA  adjusts  the  PDUFA  user  fees  on  an
annual basis. Fee waivers or reductions are available in certain circumstances, including a waiver of the application fee for the first application filed by a
small business. Additionally, no user fees are assessed on NDAs or BLAs for products designated as orphan drugs, unless the product also includes a non-
orphan indication.

The FDA also may require submission of a REMS if it believes that a risk evaluation and mitigation strategy is necessary to ensure that the benefits of the
drug  outweigh  its  risks.  A  REMS  can  include  use  of  risk  evaluation  and  mitigation  strategies  like  medication  guides,  physician  communication  plans,
assessment  plans,  and/or  elements  to  assure  safe  use,  such  as  restricted  distribution  methods,  patient  registries,  special  monitoring  or  other  risk-
minimization tools.

Table of Contents 

The  FDA  may  refer  an  application  for  a  novel  drug  or  biologic  to  an  advisory  committee.  An  advisory  committee  is  a  panel  of  independent  experts,
including clinicians and other scientific experts, which reviews, evaluates and provides a recommendation as to whether the application should be approved
and under what conditions. The FDA is not bound by the recommendations of an advisory committee, but it considers such recommendations carefully
when making decisions.

Before approving an NDA or BLA, the FDA typically will inspect the facility or facilities where the product is manufactured. The FDA will not approve an
application  unless  it  determines  that  the  manufacturing  processes  and  facilities  are  in  compliance  with  cGMP  requirements  and  are  adequate  to  assure
consistent production of the product within required specifications. Additionally, before approving an NDA or BLA, the FDA may inspect one or more
clinical trial sites to assure compliance with GCP and other requirements and the integrity of the clinical data submitted to the FDA.

After evaluating the NDA or BLA and all related information, including the advisory committee recommendation, if any, and inspection reports regarding
the  manufacturing  facilities  and  clinical  trial  sites,  the  FDA  may  issue  an  approval  letter,  or,  in  some  cases,  a  Complete  Response  Letter.  A  Complete
Response Letter indicates that the review cycle of the application is complete and the application is not ready for approval. A Complete Response Letter
generally contains a statement of specific conditions that must be met in order to secure final approval of the NDA or BLA, except that where the FDA
determines  that  the  data  supporting  the  application  are  inadequate  to  support  approval,  the  FDA  may  issue  the  Complete  Response  Letter  without  first
conducting  required  inspections,  testing  submitted  product  lots,  and/or  reviewing  proposed  labeling.  In  issuing  the  Complete  Response  Letter,  the  FDA
may  require  additional  clinical  or  preclinical  testing  or  recommend  other  actions,  such  as  requests  for  additional  information  or  clarification,  that  the
applicant  might  take  in  order  for  the  FDA  to  reconsider  the  application.  Even  with  submission  of  this  additional  information,  the  FDA  ultimately  may
decide that the application does not satisfy the regulatory criteria for approval. If and when those conditions have been met to the FDA’s satisfaction, the
FDA will typically issue an approval letter. An approval letter authorizes commercial marketing of the product with specific prescribing information for
specific indications.

Even if the FDA approves a product, depending on the specific risk(s) to be addressed it may limit the approved indications for use of the product, require
that contraindications, warnings or precautions be included in the product labeling, require that post-approval studies, including Phase 4 clinical trials, be
conducted to further assess a product’s safety after approval, require testing and surveillance programs to monitor the product after commercialization, or
impose other conditions, including distribution and use restrictions or other risk management mechanisms under a REMS, which can materially affect the
potential  market  and  profitability  of  the  product.  The  FDA  may  prevent  or  limit  further  marketing  of  a  product  based  on  the  results  of  post-marketing
studies or surveillance programs. After approval, some types of changes to the approved product, such as adding new indications, manufacturing changes,
and additional labeling claims, are subject to further testing requirements and FDA review and approval.

Orphan Drug Designation and Exclusivity

Under the Orphan Drug Act, the FDA may grant orphan drug designation to a drug or biologic intended to treat a rare disease or condition, which is a
disease or condition with either a patient population of fewer than 200,000 individuals in the United States, or a patient population greater than 200,000
individuals in the United States when there is no reasonable expectation that the cost of developing and making the product available in the United States
for the disease or condition will be recovered from sales of the product. Orphan drug designation must be requested before submitting an NDA or BLA.
After the FDA grants orphan drug designation, the generic identity of the therapeutic agent and its potential orphan use are disclosed publicly by the FDA.
Orphan  drug  designation  does  not  convey  any  advantage  in  or  shorten  the  duration  of  the  regulatory  review  and  approval  process,  though  companies
developing orphan products are eligible for certain incentives, including tax credits for qualified clinical testing and waiver of application fees.

If a product that has orphan designation subsequently receives the first FDA approval for the disease or condition for which it has such designation, the
product  is  entitled  to  a  seven-year  period  of  marketing  exclusivity  during  which  the  FDA  may  not  approve  any  other  applications  to  market  the  same
therapeutic agent for the same indication, except in limited circumstances, such as a subsequent product’s showing of clinical superiority over the product
with  orphan  exclusivity  or  where  the  original  applicant  cannot  produce  sufficient  quantities  of  product.  Competitors,  however,  may  receive  approval  of
different therapeutic agents for the indication for which the orphan product has exclusivity or obtain approval for the same therapeutic agent for a different
indication than that for which the orphan product has exclusivity. Orphan product exclusivity could block the approval of one of our products for seven
years  if  a  competitor  obtains  approval  for  the  same  therapeutic  agent  for  the  same  indication  before  we  do,  unless  we  are  able  to  demonstrate  that  our
product is clinically superior. If an orphan designated product receives marketing approval for an indication broader than what is designated, it may not be
entitled to orphan exclusivity. Further, orphan drug exclusive marketing rights in the United States may be lost if the FDA later determines that the request
for designation was materially defective or the manufacturer of the approved product is unable to assure sufficient quantities of the product to meet the
needs of patients with the rare disease or condition.

Expedited Development and Review Programs for Drugs and Biologics

The FDA maintains several programs intended to facilitate and expedite development and review of new drugs and biologics to address unmet medical
needs  in  the  treatment  of  serious  or  life-threatening  diseases  or  conditions.  These  programs  include  fast  track  designation,  breakthrough  therapy
designation, priority review and accelerated approval, and the purpose of these programs is to either expedite the development or review of important new
drugs and biologics to get them to patients more quickly than standard FDA review timelines typically permit.

A new drug or biologic is eligible for fast track designation if it is intended to treat a serious or life-threatening disease or condition and demonstrates the
potential to address unmet medical needs for such disease or condition. Fast track designation applies to the combination of the product candidate and the
specific  indication  for  which  it  is  being  studied.  Fast  track  designation  provides  increased  opportunities  for  sponsor  interactions  with  the  FDA  during
clinical development, in addition to the potential for rolling review once a marketing application is submitted. Rolling review means that the FDA may
review portions of the marketing application before the sponsor submits the complete application.

In addition, a new drug or biologic may be eligible for breakthrough therapy designation if it is intended to treat a serious or life-threatening disease or
condition and preliminary clinical evidence indicates that the drug or biologic, alone or in combination with one or more other drugs or biologics, may
demonstrate substantial improvement over existing therapies on one or more clinically significant endpoints, such as substantial treatment effects observed
early in clinical development. Breakthrough therapy designation provides all the features of fast track designation in addition to intensive guidance on an
efficient  product  development  program  beginning  as  early  as  Phase  1,  and  FDA  organizational  commitment  to  expedited  development,  including
involvement of senior managers and experienced review staff in a cross-disciplinary review, where appropriate.

Any product submitted to the FDA for approval, including a product with fast track or breakthrough therapy designation, may also be eligible for additional
FDA programs intended to expedite the review and approval process, including priority review designation and accelerated approval. A product is eligible
for  priority  review,  once  an  NDA  or  BLA  is  submitted,  if  the  product  that  is  the  subject  of  the  marketing  application  has  the  potential  to  provide  a
significant improvement in safety or effectiveness in the treatment, diagnosis or prevention of a serious disease or condition. Under priority review, the
FDA’s  goal  date  to  take  action  on  the  marketing  application  is  six  months  compared  to  ten  months  for  a  standard  review.  Products  are  eligible  for
accelerated approval if they can be shown to have an effect on a surrogate endpoint that is reasonably likely to predict clinical benefit, or an effect on a
clinical  endpoint  that  can  be  measured  earlier  than  an  effect  on  irreversible  morbidity  or  mortality,  which  is  reasonably  likely  to  predict  an  effect  on
irreversible morbidity or mortality or other clinical benefit, taking into account the severity, rarity, or prevalence of the condition and the availability or lack
of alternative treatments.

Accelerated  approval  is  usually  contingent  on  a  sponsor’s  agreement  to  conduct,  in  a  diligent  manner,  adequate  and  well-controlled  additional  post-
approval confirmatory studies to verify and describe the product’s clinical benefit. The FDA may withdraw approval of a drug or an indication approved
under accelerated approval if, for example, the confirmatory trial fails to verify the predicted clinical benefit of the product. In addition, for products being
considered for accelerated approval, the FDA generally requires, unless otherwise informed by the Agency, that all advertising and promotional materials
intended for dissemination or publication within 120 days of marketing approval be submitted to the agency for review during the pre-approval review
period.  After  the  120-day  period  has  passed,  all  advertising  and  promotional  materials  must  be  submitted  at  least  30  days  prior  to  the  intended  time  of
initial dissemination or publication.

Even if a product qualifies for one or more of these programs, the FDA may later decide that the product no longer meets the conditions for qualification or
the time period for FDA review or approval may not be shortened. Furthermore, fast track designation, breakthrough therapy designation, priority review
and accelerated approval do not change the scientific or medical standards for approval or the quality of evidence necessary to support approval, though
they may expedite the development or review process.

Pediatric Information and Pediatric Exclusivity

Under the Pediatric Research Equity Act, or PREA, as amended, certain NDAs and BLAs and certain NDA and BLA supplements must contain data that
can be used to assess the safety and efficacy of the product candidate for the claimed indications in all relevant pediatric subpopulations and to support
dosing and administration for each pediatric subpopulation for which the product is safe and effective. The FDA may grant deferrals for submission of
pediatric data or full or partial waivers. The FD&C Act requires that a sponsor who is planning to submit a marketing application for a product candidate
that  includes  a  new  active  ingredient,  new  indication,  new  dosage  form,  new  dosing  regimen  or  new  route  of  administration  submit  an  initial  Pediatric
Study Plan, or PSP, within 60 days of an end-of-Phase 2 meeting or, if there is no such meeting, as early as practicable before the initiation of the Phase 3
or Phase 2/3 study. The initial PSP must include an outline of the pediatric study or studies that the sponsor plans to conduct, including study objectives and
design, age groups, relevant endpoints and statistical approach, or a justification for not including such detailed information, and any request for a deferral
of pediatric assessments or a full or partial waiver of the requirement to provide data from pediatric studies along with supporting information. The FDA
and  the  sponsor  must  reach  an  agreement  on  the  PSP.  A  sponsor  can  submit  amendments  to  an  agreed-upon  initial  PSP  at  any  time  if  changes  to  the
pediatric plan need to be considered based on data collected from preclinical studies, early phase clinical trials and/or other clinical development programs.
Unless  otherwise  required  by  regulation,  PREA  does  not  apply  to  a  drug  or  biologic  for  an  indication  for  which  orphan  designation  has  been  granted,
except  that  PREA  will  apply  to  an  original  NDA  or  BLA  for  a  new  active  ingredient  that  is  orphan-designated  if  the  drug  or  biologic  is  a  molecularly
targeted cancer product intended for the treatment of an adult cancer and is directed at a molecular target that FDA determines to be substantially relevant
to the growth or progression of a pediatric cancer.

A drug or biologic can also obtain pediatric market exclusivity in the United States. Pediatric exclusivity, if granted, adds six months to existing exclusivity
periods and patent terms. This six-month exclusivity, which runs from the end of other exclusivity protection or patent term, may be granted based on the
voluntary completion of a pediatric study in accordance with an FDA-issued “Written Request” for such a study.

U.S. Post-Approval Requirements for Drugs and Biologics

Drugs  and  biologics  manufactured  or  distributed  pursuant  to  FDA  approvals  are  subject  to  continuing  regulation  by  the  FDA,  including,  among  other
things, requirements relating to recordkeeping, periodic reporting, product sampling and distribution, reporting of adverse experiences with the product,
complying  with  promotion  and  advertising  requirements,  which  include  restrictions  on  promoting  products  for  unapproved  uses  or  patient  populations
(known  as  “off-label  use”)  and  limitations  on  industry-sponsored  scientific  and  educational  activities.  Although  physicians  may  prescribe  approved
products for off-label uses, manufacturers may not market or promote such uses. The FDA and other agencies actively enforce the laws and regulations
prohibiting  the  promotion  of  off-label  uses,  including  not  only  by  company  employees  but  also  by  agents  of  the  company  or  those  speaking  on  the
company’s behalf, and a company that is found to have improperly promoted off-label uses may be subject to significant liability, including investigation
by federal and state authorities. Failure to comply with these requirements can result in, among other things, adverse publicity, warning letters, corrective
advertising  and  potential  civil  and  criminal  penalties,  including  liabilities  under  the  False  Claims  Act  where  products  are  obtain  reimbursement  under
federal health care programs. Promotional materials for approved drugs and biologics must be submitted to the FDA in conjunction with their first use or
first publication. Further, if there are any modifications to the drug or biologic, including changes in indications, labeling or manufacturing processes or
facilities, the applicant may be required to submit and obtain FDA approval of a new NDA or BLA or NDA or BLA supplement, which may require the
development of additional data or preclinical studies and clinical trials.

45

 
 
 
 
 
 
 
 
 
 
Table of Contents 

The FDA may impose a number of post-approval requirements as a condition of approval of an NDA or BLA. For example, the FDA may require post-
market  testing,  including  Phase  4  clinical  trials,  and  surveillance  to  further  assess  and  monitor  the  product’s  safety  and  effectiveness  after
commercialization. In addition, manufacturers and their subcontractors involved in the manufacture and distribution of approved drugs and biologics are
required  to  register  their  establishments  with  the  FDA  and  certain  state  agencies  and  are  subject  to  periodic  unannounced  inspections  by  the  FDA  and
certain  state  agencies  for  compliance  with  ongoing  regulatory  requirements,  including  cGMPs,  which  impose  certain  procedural  and  documentation
requirements on sponsors and their CMOs. Changes to the manufacturing process are strictly regulated, and, depending on the significance of the change,
may require prior FDA approval before being implemented. FDA regulations also require investigation and correction of any deviations from cGMP and
impose  reporting  requirements  upon  us  and  any  third  party  manufacturers  that  a  sponsor  may  use.  Manufacturers  and  manufacturers’  facilities  are  also
required to comply with applicable product tracking and tracing requirements. Accordingly, manufacturers must continue to expend time money and effort
in  the  area  of  production  and  quality  control  to  maintain  compliance  with  cGMP  and  other  aspects  of  regulatory  compliance.  Failure  to  comply  with
statutory  and  regulatory  requirements  may  subject  a  manufacturer  to  possible  legal  or  regulatory  action,  such  as  warning  letters,  suspension  of
manufacturing, product seizures, injunctions, civil penalties or criminal prosecution. There is also a continuing, annual program user fee for any marketed
product.

The FDA may withdraw approval of a product if compliance with regulatory requirements and standards is not maintained or if problems occur after the
product  reaches  the  market.  Later  discovery  of  previously  unknown  problems  with  a  product,  including  adverse  events  of  unanticipated  severity  or
frequency, or with manufacturing processes, or failure to comply with regulatory requirements, may result in revisions to the approved labeling to add new
safety information, requirements for post-market studies or clinical trials to assess new safety risks, or imposition of distribution or other restrictions under
a REMS. Other potential consequences include, among other things:

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

● the  issuance  of  safety  alerts,  Dear  Healthcare  Provider  letters,  press  releases  or  other  communications  containing  warnings  or  other  safety

information about the product;

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

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

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

● injunctions or the imposition of civil or criminal penalties; and

● consent decrees, corporate integrity agreements, debarment or exclusion from federal healthcare programs; or

● mandated modification of promotional materials and labeling and issuance of corrective information.

United States Patent Term Restoration and Marketing Exclusivity

Depending  upon  the  timing,  duration  and  specifics  of  FDA  approval  of  our  product  candidates,  some  of  our  United  States  patents  may  be  eligible  for
limited patent term extension under the Drug Price Competition and Patent Term Restoration Act of 1984, commonly referred to as the Hatch-Waxman
Amendments. The Hatch-Waxman Amendments permit restoration of the patent term of up to five years as compensation for patent term lost during the
FDA  regulatory  review  process.  Patent  term  restoration,  however,  cannot  extend  the  remaining  term  of  a  patent  beyond  a  total  of  14  years  from  the
product’s  approval  date  and  only  those  claims  covering  such  approved  drug  product,  a  method  for  using  it  or  a  method  for  manufacturing  it  may  be
extended. The patent term restoration period is generally one-half the time between the effective date of an IND and the submission date of an NDA or
BLA plus the time between the submission date of an NDA or BLA and the approval of that application, except that the review period is reduced by any
time  during  which  the  applicant  failed  to  exercise  due  diligence.  Only  one  patent  applicable  to  an  approved  drug  is  eligible  for  the  extension  and  the
application for the extension must be submitted prior to the expiration of the patent. The U.S. PTO, in consultation with the FDA, reviews and approves the
application  for  any  patent  term  extension  or  restoration.  In  the  future,  we  may  apply  for  restoration  of  patent  term  for  our  currently  owned  or  licensed
patents to add patent life beyond a patent’s current expiration date, depending on the expected length of the clinical trials and other factors involved in the
filing of the relevant NDA or BLA.

Marketing exclusivity provisions under the FD&C Act also can delay the submission or the approval of certain applications. The FD&C Act provides a
five-year period of non-patent marketing exclusivity within the United States to the first applicant to gain approval of an NDA for a new chemical entity. A
drug is a new chemical entity if the FDA has not previously approved any other new drug containing the same active moiety, which is the molecule or ion
responsible for the action of the drug substance. During the exclusivity period, the FDA may not accept for review an Abbreviated New Drug Application,
or ANDA, or a 505(b)(2) NDA submitted by another company for another version of such drug where the applicant does not own or have a legal right of
reference to all the data required for approval. However, an application may be submitted after four years if it contains a certification of patent invalidity or
non-infringement. The FD&C Act also provides three years of marketing exclusivity for an NDA, 505(b)(2) NDA or supplement to an existing NDA if new
clinical investigations, other than bioavailability studies, that were conducted or sponsored by the applicant are deemed by the FDA to be essential to the
approval  of  the  application,  for  example,  for  new  indications,  dosages  or  strengths  of  an  existing  drug.  This  three-year  exclusivity  covers  only  the
conditions of use associated with the new clinical investigations and does not prohibit the FDA from approving ANDAs for drugs containing the original
active agent. Five-year and three-year exclusivity will not delay the submission or approval of a full NDA. However, an applicant submitting a full NDA
would  be  required  to  conduct  or  obtain  a  right  of  reference  to  all  of  the  preclinical  studies  and  adequate  and  well-controlled  clinical  trials  necessary  to
demonstrate safety and effectiveness.

Biosimilars and Exclusivity

The ACA includes a subtitle called the Biologics Price Competition and Innovation Act, or BPCIA, which created an abbreviated approval pathway for
biological  products  that  are  biosimilar  to  or  interchangeable  with  an  FDA-licensed  reference  biological  product.  The  FDA  has  issued  several  guidance
documents  outlining  an  approach  to  review  and  approval  of  biosimilars  in  the  United  States.  Biosimilarity,  which  requires  that  there  be  no  clinically
meaningful differences between the biological product and the reference product in terms of safety, purity, and potency, can be shown through analytical
studies, animal studies, and a clinical study or studies. Interchangeability requires that a product is biosimilar to the reference product and the product must
demonstrate that it can be expected to produce the same clinical results as the reference product in any given patient and, for products that are administered
multiple times to an individual, the biologic and the reference biologic may be alternated or switched after one has been previously administered without
increasing safety risks or risks of diminished efficacy relative to exclusive use of the reference biologic.

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

Other Regulatory Matters

Following  product  approval,  where  applicable,  the  manufacturing,  sales,  promotion  and  other  activities  around  product  candidates  and/or
commercialization are also subject to regulation by numerous regulatory authorities in the United States in addition to the FDA. Regulatory agencies with
authority  over  product  candidates  may  include,  and  are  not  limited  to,  the  Centers  for  Medicare  &  Medicaid  Services,  other  divisions  of  the  U.S.
Department of Health and Human Services, the Department of Justice, the Drug Enforcement Administration, the Consumer Product Safety Commission,
the Federal Trade Commission, the Occupational Safety & Health Administration, the Environmental Protection Agency and state and local governments
and governmental agencies.

If  any  products  that  we  may  develop  are  made  available  to  authorized  users  of  the  Federal  Supply  Schedule  of  the  General  Services  Administration,
additional laws and requirements apply. Products must meet applicable child-resistant packaging requirements under the U.S. Poison Prevention Packaging
Act.  Manufacturing,  labeling,  packaging,  distribution,  sales,  promotion  and  other  activities  also  are  potentially  subject  to  federal  and  state  consumer
protection and unfair competition laws, among other requirements to which we may be subject.

The distribution of pharmaceutical products is subject to additional requirements and regulations, including extensive recordkeeping, licensing, storage and
security requirements intended to prevent the unauthorized sale of pharmaceutical products.

The failure to comply with any of these laws or regulatory requirements may subject firms to legal or regulatory action. Depending on the circumstances,
failure to meet applicable regulatory requirements can result in criminal prosecution, fines or other penalties, injunctions, exclusion from federal healthcare
programs,  requests  for  recall,  seizure  of  products,  total  or  partial  suspension  of  production,  denial  or  withdrawal  of  product  approvals,  relabeling  or
repackaging, or refusal to allow a firm to enter into supply contracts, including government contracts. Any claim or action against us for violation of these
laws, even if we successfully defend against it, could cause us to incur significant legal expenses and divert our management’s attention from the operation
of our business. Prohibitions or restrictions on marketing, sales or withdrawal of future products marketed by us could materially affect our business in an
adverse way.

Changes in regulations, statutes or the interpretation of existing regulations could impact our business in the future by requiring, for example: (i) changes to
our manufacturing arrangements; (ii) additions or modifications to product labeling or packaging; (iii) the recall or discontinuation of our products; or (iv)
additional recordkeeping requirements. If any such changes were to be imposed, they could adversely affect the operation of our business.

Other Healthcare Laws

If we obtain regulatory approval of our products, we may be subject to various federal and state laws targeting fraud, waste, and abuse in the healthcare
industry. These laws may impact, among other things, our proposed sales, marketing, and education programs. In addition, we may be subject to patient
privacy regulation by both the federal government and the states in which we conduct our business. The U.S. laws that may affect our ability to operate
include:

● the U.S. federal Anti-Kickback Statute, which prohibits, among other things, persons from knowingly and willfully soliciting, receiving, offering or
paying remuneration, directly or indirectly, to induce, or in return for, either the referral of an individual, or the purchase or recommendation of an item
or  service  for  which  payment  may  be  made  under  a  federal  healthcare  program,  such  as  the  Medicare  and  Medicaid  programs.  In  addition,  the
government may assert that a claim including items or services resulting from a violation of the federal Anti-Kickback Statute constitutes a false or
fraudulent claim for purposes of the federal civil False Claims Act or federal civil money penalties statute (as discussed below);

● U.S. federal civil and criminal false claims laws and civil monetary penalty laws, including the federal False Claims Act, which impose criminal and
civil penalties against individuals or entities for knowingly presenting, or causing to be presented, to the federal government, including the Medicare
and Medicaid programs, claims for payment that are false or fraudulent, making a false statement to avoid, decrease or conceal an obligation to pay
money to the federal government, or knowingly concealing or knowingly and improperly avoiding or decreasing such an obligation;

● the U.S. federal Health Insurance Portability and Accountability Act of 1996, or HIPAA and its implementing regulations, which created new federal
criminal  statutes  that  prohibit  executing  a  scheme  to  defraud  any  healthcare  benefit  program  and  prohibit  knowingly  and  willfully  falsifying,
concealing  or  covering  up  a  material  fact  or  making  any  materially  false  statements  in  connection  with  the  delivery  of  or  payment  for  healthcare
benefits, items or services;

● HIPAA,  as  amended  by  the  Health  Information  Technology  for  Economic  and  Clinical  Health  Act  of  2009,  or  HITECH,  and  their  respective
implementing regulations, which impose certain obligations, including mandatory contractual terms, on covered healthcare providers, health plans, and

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
healthcare  clearinghouses,  as  well  as  their  business  associates,  with  respect  to  safeguarding  the  privacy,  security  and  transmission  of  individually
identifiable health information;

● the U.S. federal Physician Payments Sunshine Act which requires certain manufacturers of drugs, devices, biologics, and medical supplies for which
payment is available under Medicare, Medicaid, or the Children’s Health Insurance Program, with specific exceptions, to report annually to the Centers
for  Medicare  &  Medicaid  Services  information  related  to  payments  or  transfers  of  value  made  to  physicians  (currently  defined  to  include  doctors,
dentists,  optometrists,  podiatrists  and  chiropractors),  physician  assistants,  nurse  practitioners,  clinical  nurse  specialists,  certified  registered  nurse
anesthetists and teaching hospitals, as well as information regarding ownership and investment interests held by the physicians described above and
their immediate family members;

● federal  government  price  reporting  laws,  which  require  us  to  calculate  and  report  complex  pricing  metrics  in  an  accurate  and  timely  manner  to

government programs;

● federal consumer protection and unfair competition laws, which broadly regulate marketplace activities and activities that potentially harm consumers;

and

● analogous  state  and  laws  and  regulations  in  other  jurisdictions,  such  as  state  anti-kickback  and  false  claims  laws,  which  may  apply  to  sales  or
marketing  arrangements  and  claims  involving  healthcare  items  or  services  reimbursed  by  non-governmental  third-party  payers,  including  private
insurers, and  state  and  laws  in  other  jurisdiction  governing  the  privacy  and  security  of  health  information  in  certain  circumstances,  many  of  which
differ from each other in significant ways and often are not preempted by HIPAA, thus complicating compliance efforts.

47

 
 
 
 
 
Table of Contents 

Many U.S. states have adopted laws similar to the federal Anti-Kickback Statute and False Claims Act, and may apply to our business practices, including,
but  not  limited  to,  research,  distribution,  sales  or  marketing  arrangements  and  claims  involving  healthcare  items  or  services  reimbursed  by  non-
governmental payers, including private insurers. In addition, some states have passed laws that require pharmaceutical companies to comply with the April
2003 Office of Inspector General Compliance Program Guidance for Pharmaceutical Manufacturers and/or the Pharmaceutical Research and Manufacturers
of  America’s  Code  on  Interactions  with  Healthcare  Professionals.  Several  states  also  impose  other  marketing  restrictions  or  require  pharmaceutical
companies to make marketing or price disclosures to the state and require the registration of pharmaceutical sales representatives.

At  the  state  level,  legislatures  have  increasingly  passed  legislation  and  implemented  regulations  designed  to  control  pharmaceutical  product  pricing,
including  price  or  patient  reimbursement  constraints,  discounts,  restrictions  on  certain  product  access  and  marketing  cost  disclosure  and  transparency
measures, and, in some cases, designed to encourage importation from other countries and bulk purchasing.

Because of the breadth of these laws and the narrowness of the statutory exceptions and safe harbors available, in the event we obtain regulatory approval
for any one of our products, it is possible that some of our business activities could be subject to challenge and found to violate one or more of such laws,
regulations, and guidance. Law enforcement authorities are increasingly focused on enforcing fraud and abuse laws, and it is possible that some of our
practices  may  be  challenged  under  these  laws.  Violations  of  these  laws  can  subject  us  to  administrative,  civil  and  criminal  penalties,  damages,  fines,
disgorgement, the exclusion from participation in federal and state healthcare programs, individual imprisonment, reputational harm, and the curtailment or
restructuring of our operations, as well as additional reporting obligations and oversight if we become subject to a corporate integrity agreement or other
agreement to resolve allegations of non-compliance with these laws. Efforts to ensure that our current and future business arrangements with third parties,
and our business generally, will comply with applicable healthcare laws and regulations will involve substantial costs.

Insurance Coverage and Reimbursement

Significant uncertainty exists as to the coverage and reimbursement status of any drug products for which we may obtain regulatory approval. In the United
States, sales of any products for which we may receive regulatory approval for commercial sale will depend in part on the availability of coverage and
reimbursement from third-party payers. Third-party payers include government programs such as Medicare and Medicaid, managed care providers, private
health insurers, and other organizations. The process for determining whether a payer will provide coverage for a drug product may be separate from the
process for setting the reimbursement rate that the payer will pay for the drug product. In the United States, the principal decisions about reimbursement for
new  medicines  are  typically  made  by  CMS,  an  agency  within  HHS.  CMS  decides  whether  and  to  what  extent  a  new  medicine  will  be  covered  and
reimbursed under Medicare and private payers tend to follow CMS to a substantial degree. Third-party payers may limit coverage to specific drug products
on  an  approved  list,  or  formulary,  which  might  not  include  all  of  the  FDA-approved  drugs  for  a  particular  indication.  Moreover,  a  payer’s  decision  to
provide coverage for a drug product does not imply that an adequate reimbursement rate will be approved. Adequate third-party reimbursement may not be
available to enable us to maintain price levels sufficient to realize an appropriate return on our investment in product development. Third-party payers are
increasingly challenging the price and examining the medical necessity and cost- effectiveness of medical products and services, in addition to their safety
and  efficacy.  In  order  to  obtain  coverage  and  reimbursement  for  any  product  that  might  be  approved  for  sale,  we  may  need  to  conduct  expensive
pharmacoeconomic studies in order to demonstrate the medical necessity and cost-effectiveness of any products, in addition to the costs required to obtain
regulatory approvals. Factors payers consider in determining reimbursement are based on whether the product is:

● a covered benefit under its health plan;

● safe, effective and medically necessary;

● appropriate for the specific patient;

● cost-effective; and

● neither experimental nor investigational.

Our product candidates may not be considered medically necessary or cost-effective. If third-party payers do not consider a product to be cost-effective
compared to other available therapies, they may not cover the product after approval as a benefit under their plans or, if they do, the level of payment may
not be sufficient to allow a company to sell its products at a profit.

The U.S. government and state legislatures have shown significant interest in implementing cost containment programs to limit the growth of government-
paid health care costs, including price controls, restrictions on reimbursement and requirements for substitution of generic products for branded prescription
drugs. For example, the ACA contains provisions that may reduce the profitability of drug products, including, for example, increased rebates for drugs
reimbursed  by  Medicaid  programs,  extension  of  Medicaid  rebates  to  Medicaid  managed  care  plans,  mandatory  discounts  for  certain  Medicare  Part  D
beneficiaries,  and  annual  fees  based  on  pharmaceutical  companies’  share  of  sales  to  federal  health  care  programs.  At  the  state  level,  legislatures  have
increasingly passed legislation and implemented regulations designed to control pharmaceutical product pricing, including price or patient reimbursement
constraints,  discounts,  restrictions  on  certain  product  access  and  marketing  cost  disclosure  and  transparency  measures,  and,  in  some  cases,  designed  to
encourage importation from other countries and bulk purchasing. Adoption of government controls and measures, and tightening of restrictive policies in
jurisdictions with existing controls and measures, could limit payments for pharmaceuticals.

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

Current and Future Healthcare Reform Legislation

The United States and many foreign jurisdictions have enacted or proposed legislative and regulatory changes affecting the healthcare system that could
prevent  or  delay  marketing  approval  of  our  product  candidates,  restrict  or  regulate  post-approval  activities  and  affect  our  ability  to  profitably  sell  any
product for which we obtain marketing approval. Changes in regulations, statutes or the interpretation of existing regulations could impact our business in
the future by requiring, for example: (i) changes to our manufacturing arrangements; (ii) additions or modifications to product labeling; (iii) the recall or
discontinuation of our products; or (iv) additional record-keeping requirements.

In  March  2010,  the  ACA  was  enacted,  which  includes  measures  that  have  or  will  significantly  change  the  way  health  care  is  financed  by  both  U.S.
governmental and private insurers. Among the provisions of the ACA of greatest importance to the pharmaceutical industry are the following:

● The  Medicaid  Drug  Rebate  Program  requires  pharmaceutical  manufacturers  to  enter  into  and  have  in  effect  a  national  rebate  agreement  with  the
Secretary of the Department of HHS as a condition for states to receive federal matching funds for the manufacturer’s outpatient drugs furnished to
Medicaid patients. The ACA made several changes to the Medicaid Drug Rebate Program, including increasing pharmaceutical manufacturers’ rebate
liability by raising the minimum basic Medicaid rebate on most branded prescription drugs from 15.1% of average manufacturer  price,  or  AMP,  to
23.1% of average manufacturer price, or AMP, and adding a new  rebate  calculation  for  “line  extensions”  (i.e.,  new  formulations,  such  as  extended
release formulations) of solid oral dosage forms of branded products, as well as potentially impacting their rebate liability by modifying the statutory
definition of AMP. The ACA also expanded the universe of Medicaid utilization subject to drug rebates by requiring pharmaceutical manufacturers to
pay rebates on Medicaid managed care utilization and by expanding the  population  potentially  eligible  for  Medicaid  drug  benefits.  In  addition,  the
ACA provides for the public availability of retail survey prices and certain weighted average AMPs under the Medicaid program.

● In order for a pharmaceutical product to receive federal reimbursement under the Medicare Part B and Medicaid programs or to be sold directly to U.S.
government agencies, the manufacturer must extend discounts to entities eligible to participate in the 340B drug pricing program. The required 340B
discount on a given product is calculated based on the AMP and Medicaid rebate amounts reported by the manufacturer. The ACA expanded the types
of entities eligible to receive discounted 340B pricing, although, under the current state of the law, with the exception of children’s hospitals, these
newly eligible entities will not be eligible to receive discounted 340B pricing on orphan drugs when used for the orphan indication. In addition, as
340B drug pricing is determined based on AMP and Medicaid rebate data, the revisions to the Medicaid rebate formula and AMP definition described
above could cause the required 340B discount to increase.

● Expansion of the eligibility criteria for Medicaid programs by, among other things, allowing states to offer Medicaid coverage to additional individuals
and  by  adding  new  mandatory  eligibility  categories  for  certain  individuals  with  income  at  or  below  133%  of  the  Federal  Poverty  Level,  thereby
potentially increasing manufacturers’ Medicaid rebate liability.

● The ACA imposed a requirement on manufacturers of branded drugs to provide a 70% discount off the negotiated price of branded drugs dispensed to

Medicare Part D patients in the coverage gap (increased from 50% pursuant to the Bipartisan Budget Act of 2018, effective as of 2019).

● The ACA imposed an annual, nondeductible fee on any entity that manufactures or imports certain branded  prescription  drugs,  apportioned  among
these entities according to their market share in certain government healthcare programs, although this fee would not apply to sales of certain products
approved exclusively for orphan indications.

● A  Patient-Centered  Outcomes  Research  Institute  was  established  pursuant  to  the  ACA  to  oversee,  identify  priorities  in,  and  conduct  comparative
clinical effectiveness research, along with funding for such research. The research conducted by the Patient-Centered Outcomes Research Institute may
affect the market for certain pharmaceutical products.

● The ACA  established  the  Center  for  Medicare  and  Medicaid  Innovation  within  CMS,  which  is  charged  with  testing  new,  innovative  payment  and

service delivery models.

Since its enactment, there have been judicial, Congressional and executive challenges to certain aspects of the ACA. On June 17, 2021, the U.S. Supreme
Court dismissed the most recent judicial challenge to the ACA brought by several states without specifically ruling on the constitutionality of the ACA.
Prior to the Supreme Court’s decision, President Biden issued an executive order to initiate a special enrollment period from February 15, 2021 through
August  15,  2021  for  purposes  of  obtaining  health  insurance  coverage  through  the  ACA  marketplace.  The  executive  order  also  instructed  certain
governmental  agencies  to  review  and  reconsider  their  existing  policies  and  rules  that  limit  access  to  healthcare,  including  among  others,  reexamining
Medicaid demonstration projects and waiver programs that include work requirements, and policies that create unnecessary barriers to obtaining access to
health insurance coverage through Medicaid or the ACA. It is unclear how other healthcare reform measures of the Biden administration or other efforts, if
any, to challenge, repeal or replace the ACA will impact our business.

In addition, other legislative and regulatory changes have been proposed and adopted in the United States since the ACA was enacted:

● On August 2, 2011, the U.S. Budget Control Act of 2011, among other things, included aggregate reductions of Medicare payments to providers of 2%
per fiscal year. These reductions went into effect on April 1, 2013 and, due to subsequent legislative amendments to the statute, will remain in effect
through 2030, with the exception of a temporary suspension from May 1, 2020 through March 31, 2022 due to the COVID-19 pandemic. Following
the temporary suspension, a  1%  payment  reduction  will  occur  beginning  April  1,  2022  through  June  30,  2022,  and  the  2% payment reduction will
resume on July 1, 2022.

● On January  2,  2013,  the  U.S.  American  Taxpayer  Relief  Act  of  2012  was  signed  into  law,  which,  among  other  things,  further  reduced  Medicare

payments to several types of providers.

● On April 13, 2017, CMS published a final rule that gives states greater flexibility in setting benchmarks for insurers in the individual and small group
marketplaces, which may have the effect of relaxing the essential health benefits required under the ACA for plans sold through such marketplaces.

● On May 30, 2018, the Right to Try Act, was signed into law. The law, among other things, provides a federal framework for certain patients to access
certain investigational new drug products that have completed a Phase 1 clinical trial and that are undergoing investigation for FDA  approval. Under
certain circumstances, eligible patients can seek treatment without enrolling in clinical trials and without obtaining FDA permission under the FDA
expanded access program. There is no obligation for a pharmaceutical manufacturer to make its drug products available to eligible patients as a result
of the Right to Try Act.

● On May 23, 2019, CMS published a final rule to allow Medicare Advantage Plans the option of using step therapy for Part B drugs beginning January

1, 2020.

● On  December  20,  2019,  former  President  Trump  signed  into  law  the  Further  Consolidated  Appropriations  Act  (H.R.  1865),  which  repealed  the
Cadillac tax, the health insurance provider tax, and the medical device excise tax. It is impossible to determine whether similar taxes could be instated
in the future.

Additionally, there has been increasing legislative and enforcement interest in the United States with respect to drug pricing practices. Specifically, there
has been heightened governmental scrutiny over the manner in which manufacturers set prices for their marketed products, which has resulted in several
U.S.  Congressional  inquiries  and  proposed  and  enacted  federal  and  state  legislation  designed  to,  among  other  things,  bring  more  transparency  to  drug
pricing, reduce the cost of prescription drugs under Medicare, and review the relationship between pricing and manufacturer patient programs. At a federal
level, President Biden signed an Executive Order on July 9, 2021 affirming the administration’s policy to (i) support legislative reforms that would lower
the prices of prescription drug and biologics, including by allowing Medicare to negotiate drug prices, by imposing inflation caps, and, by supporting the
development and market entry of lower-cost generic drugs and biosimilars; and (ii) support the enactment of a public health insurance option. Among other
things, the Executive Order also directs HHS to provide a report on actions to combat excessive pricing of prescription drugs, enhance the domestic drug
supply chain, reduce the price that the Federal government pays for drugs, and address price gouging in the industry; and directs the FDA to work with
states and Indian Tribes that propose to develop section 804 Importation Programs in accordance with the Medicare Prescription Drug, Improvement, and
Modernization Act of 2003, and the FDA’s implementing regulations. FDA released such implementing regulations on September 24, 2020, which went
into effect on November 30, 2020, providing guidance for states to build and submit importation plans for drugs from Canada. On September 25, 2020,
CMS stated drugs imported by states under this rule will not be eligible for federal rebates under Section 1927 of the Social Security Act and manufacturers
would not report these drugs for “best price” or Average Manufacturer Price purposes. Since these drugs are not considered covered outpatient drugs, CMS
further  stated  it  will  not  publish  a  National  Average  Drug  Acquisition  Cost  for  these  drugs.  If  implemented,  importation  of  drugs  from  Canada  may
materially and adversely affect the price we receive for any of our product candidates. Further, on November 20, 2020 CMS issued an Interim Final Rule
implementing  the  Most  Favored  Nation,  or  MFN,  Model  under  which  Medicare  Part  B  reimbursement  rates  would  have  been  be  calculated  for  certain
drugs and biologicals based on the lowest price drug manufacturers receive in Organization for Economic Cooperation and Development countries with a
similar gross domestic product per capita. However, on December 29, 2021 CMS rescinded the Most Favored Nations rule. Additionally, on November 30,
2020, HHS published a regulation removing safe harbor protection for price reductions from pharmaceutical manufacturers to plan sponsors under Part D,
either  directly  or  through  pharmacy  benefit  managers,  unless  the  price  reduction  is  required  by  law.  The  rule  also  creates  a  new  safe  harbor  for  price
reductions reflected at the point-of-sale, as well as a safe harbor for certain fixed fee arrangements between pharmacy benefit managers and manufacturers.
Pursuant  to  court  order,  the  removal  and  addition  of  the  aforementioned  safe  harbors  were  delayed  and  recent  legislation  imposed  a  moratorium  on
implementation of the rule until January 1, 2026. Although a number of these and other proposed measures may require authorization through additional
legislation to become effective, and the Biden administration may reverse or otherwise change these measures, both the Biden administration and Congress
have indicated that they will continue to seek new legislative measures to control drug costs.

We expect that additional U.S. federal healthcare reform measures will be adopted in the future, any of which could limit the amounts that the U.S. Federal
Government will pay for healthcare drugs and services, which could result in reduced demand for our drug candidates or additional pricing pressures.

Other U.S. Environmental, Health and Safety Laws and Regulations

We may be 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.  From  time  to  time  and  in  the  future,  our  operations  may  involve  the  use  of
hazardous and flammable materials, including chemicals and biological materials, and may also produce hazardous waste products. Even if we contract
with third parties for the disposal of these materials and waste products, we cannot completely eliminate the risk of contamination or injury resulting from
these  materials.  In  the  event  of  contamination  or  injury  resulting  from  the  use  or  disposal  of  our  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
for failure to comply with such laws and regulations.

We maintain workers’ compensation insurance to cover us for costs and expenses that we may incur due to injuries to our employees, but this insurance
may not provide adequate coverage against potential liabilities. However, we do not maintain insurance for environmental liability or toxic tort claims that
may be asserted against us.

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

Government Regulation of Drugs and Biologics Outside of the United States

In addition to regulations in the United States, we will be subject to a variety of regulations in other jurisdictions governing, among other things, clinical
trials  and  any  commercial  sales  and  distribution  of  our  products.  The  cost  of  establishing  a  regulatory  compliance  system  for  numerous  varying
jurisdictions can be very significant. Although many of the issues discussed above with respect to the United States apply similarly in the context of the
European Union and in other jurisdictions, the approval process varies between countries and jurisdictions and can involve additional product testing and
additional administrative review periods. The time required to obtain approval in other countries and jurisdictions might differ from and be longer than that
required to obtain FDA approval. Regulatory approval in one country or jurisdiction does not ensure regulatory approval in another, but a failure or delay in
obtaining regulatory approval in one country or jurisdiction may negatively impact the regulatory process in others.

Whether or not we obtain FDA approval for a product, we must obtain the requisite approvals from regulatory authorities in foreign countries prior to the
commencement of clinical trials or marketing of the product in those countries. Certain countries outside of the United States have a similar process that
requires the submission of a clinical trial application much like the IND prior to the commencement of human clinical trials. In the European Union, for
example,  a  request  for  a  clinical  trial  authorization,  or  CTA,  must  be  submitted  to  each  country’s  national  health  authority  and  an  independent  ethics
committee,  much  like  the  FDA  and  the  IRB,  respectively.  Once  the  CTA  is  approved  in  accordance  with  a  country’s  requirements,  clinical  trial
development may proceed.

The European Union adopted the new Clinical Trials Regulation (EU) No 536/2014 in April 2014, which replaced the Clinical Trials Directive 2001/20/EC
on January 31, 2022. The transitory provisions of the new Regulation offer sponsors the possibility to choose between the requirements of the previous
Directive and the new Regulation if the request for authorization of a clinical trial is submitted in the year after the new Regulation became applicable. If
the  sponsor  chooses  to  submit  under  the  Directive,  the  clinical  trial  continues  to  be  governed  by  the  previous  Directive  until  three  years  after  the  new
Regulation became applicable. If a clinical trial continues for more than three years after the Regulation became applicable, the new Regulation will at that
time begin to apply to the clinical trial. The new Regulation overhauls the system of approvals for clinical trials in the European Union. Specifically, it is
directly applicable in all Member States (meaning that no national implementing legislation in each Member State is required), and aims at simplifying and
streamlining  the  approval  of  clinical  trials  in  the  European  Union.  The  main  characteristics  of  the  new  Regulation  include:  a  streamlined  application
procedure  via  a  single-entry  point  through  the  Clinical  Trials  Information  System;  a  single  set  of  documents  to  be  prepared  and  submitted  for  the
application as well as simplified reporting procedures for clinical trial sponsors; and a harmonized procedure for the assessment of applications for clinical
trials,  which  is  divided  in  two  parts  (Part  I  contains  scientific  and  medicinal  product  documentation  and  Part  II  contains  the  national  and  patient-level
documentation). Part I is assessed by a coordinated review by the competent authorities of all European Union Member States in which an application for
authorization of a clinical trial has been submitted (Concerned Member States) of a draft report prepared by a Reference Member State. Part II is assessed
separately by each Concerned Member State. Strict deadlines have also been established for the assessment of clinical trial applications.

The  requirements  and  process  governing  the  conduct  of  clinical  trials,  product  approval  or  licensing,  pricing  and  reimbursement  vary  from  country  to
country. In all cases, the clinical trials are conducted in accordance with GCP, the applicable regulatory requirements and the ethical principles that have
their origin in the Declaration of Helsinki.

To obtain regulatory approval of a medicinal product under European Union regulatory systems, we must submit a marketing authorization application. The
application required in the European Union is similar to an NDA or BLA in the United States, with the exception of, among other things, country-specific
document requirements. Marketing approvals in multiple European Union Member States may be obtained through a centralized, mutual recognition or
decentralized  procedure.  The  centralized  procedure  results  in  the  grant  of  a  single  marketing  authorization  that  is  valid  throughout  the  European  Union
Member States, as well as the additional Member States of the European Economic Area (Norway, Iceland and Liechtenstein).

Pursuant to Regulation (EC) No. 726/2004, as amended, the centralized procedure is mandatory for certain products, including those developed by means
of  specified  biotechnological  processes,  advanced  therapy  medicinal  products  (gene-therapy,  somatic-cell  therapy,  and  tissue-engineered  products),
products for human use containing a new active substance for which the therapeutic indication is the treatment of specified diseases, including AIDS, HIV,
cancer, diabetes, neurodegenerative disorders, auto-immune diseases and other immune dysfunctions and viral diseases, as well as products designated as
orphan medicinal products. The Committee for Medicinal Products for Human Use, or CHMP, of the EMA also has the discretion to permit other products
to use the centralized procedure if it considers them sufficiently innovative or they contain a new active substance or they may be of benefit to public health
at the European Union level.

Under the centralized procedure in the European Union, the maximum timeframe for the evaluation of a marketing authorization application by the EMA is
210  days,  excluding  clock  stops,  when  additional  written  or  oral  information  is  to  be  provided  by  the  applicant  in  response  to  questions  asked  by  the
CHMP. Clock stops may extend the timeframe of evaluation of a marketing authorization application considerably beyond 210 days. Where the CHMP
gives a positive opinion, it provides the opinion together with supporting documentation to the European Commission, who makes the final decision to
grant a marketing authorization, which is issued within 67 days of receipt of the EMA’s recommendation. Accelerated evaluation might be granted by the
CHMP in exceptional cases, when a medicinal product is expected to be of major interest from the point of view of public health and in particular from the
viewpoint of therapeutic innovation. If the CHMP accepts such request, the time limit of 210 days will be reduced to 150 days, excluding clock stops, but it
is possible that the CHMP can revert to the standard time limit for the centralized procedure if it considers that it is no longer appropriate to conduct an
accelerated assessment.

Now that the UK (which comprises Great Britain and Northern Ireland) has left the European Union, Great Britain will no longer be covered by centralized
marketing authorizations (under the Northern Ireland Protocol, centralized marketing authorizations will continue to be recognized in Northern Ireland). All
medicinal products with a current centralized marketing authorization were automatically converted to Great Britain marketing authorizations on January 1,
2021.  For  a  period  of  two  years  from  January  1,  2021,  the  Medicines  and  Healthcare  products  Regulatory  Agency  the  United  Kingdom’s  medicines
regulator, may rely on a decision taken by the European Commission on the approval of a new marketing authorization in the centralized procedure, in
order to more quickly grant a new Great Britain marketing authorization. A separate application will, however, still be required.

The European Union also provides opportunities for market exclusivity. For example, in the European Union, upon receiving marketing authorization, new
chemical innovative medicinal products generally receive eight years of data exclusivity and an additional two years of market exclusivity. If granted, data
exclusivity  prevents  applicants  for  authorization  of  generics  or  biosimilars  of  these  innovative  products  in  the  European  Union  from  referencing  the
innovator’s preclinical and clinical trial data when applying for a generic or biosimilar marketing authorization in the European Union, during a period of
eight  years  from  the  date  on  which  the  reference  product  was  first  authorized  in  the  European  Union.  During  the  additional  two-year  period  of  market
exclusivity, a generic marketing authorization can be submitted, and the innovator’s data may be referenced, but no generic product can be marketed until
the  expiration  of  the  market  exclusivity.  The  innovator  may  obtain  an  additional  one  year  of  market  exclusivity  if  the  innovator  obtains  an  additional
authorization  during  the  initial  eight  year  period  for  one  or  more  new  indications  that  demonstrate  significant  clinical  benefit  over  currently  approved
therapies.  Even  if  a  product  is  considered  to  be  an  innovative  medicinal  product  so  that  the  innovator  gains  the  prescribed  period  of  data  exclusivity,
another  company  may  market  another  version  of  the  product  if  such  company  obtained  a  marketing  authorization  based  on  a  marketing  authorization
application with a completely independent data package of pharmaceutical tests, preclinical tests and clinical trials. However, there is no guarantee that a
product will be considered by the European Union’s regulatory authorities to be a new chemical entity, and products may not qualify for data exclusivity.
Similar exclusivity periods are available for new biologics.

A product can be designated as an orphan medicinal product by the European Commission if its sponsor can establish: that (1) the product is intended for
the diagnosis, prevention or treatment of a life-threatening or chronically debilitating condition; (2) either (a) such condition affects no more than five in
10,000 persons in the European Union when the application is made, or (b) it is unlikely that the product, without the benefits derived from orphan status,
would generate sufficient return in the European Union to justify the necessary investment in its development; and (3) there exists no satisfactory method
of diagnosis, prevention or treatment of such condition authorized for marketing in the European Union or, if such method exists, the product will be of
significant  benefit  to  those  affected  by  that  condition.  Orphan  medicinal  products  are  eligible  for  financial  incentives  such  as  reduction  of  fees  or  fee
waivers.  The  application  for  orphan  designation  must  be  submitted  before  the  application  for  marketing  authorization.  The  applicant  will  receive  a  fee
reduction for the marketing authorization application if the orphan designation has been granted, but not if the designation is still pending at the time the
marketing authorization is submitted. Orphan designation does not convey any advantage in, or shorten the duration of, the regulatory review and approval
process.

Orphan medicinal products in the European Union are eligible for 10-year market exclusivity during which time no “similar medicinal product” may be
placed on the market. A “similar medicinal product” is defined as a medicinal product containing a similar active substance or substances as contained in
an authorized orphan medicinal product, and which is intended for the same therapeutic indication. This 10-year market exclusivity may be reduced to six
years if, at the end of the fifth year, it is established that the product no longer meets the criteria for orphan designation, for example, if the product is
sufficiently profitable not to justify maintenance of market exclusivity. Additionally, marketing authorization may be granted to a similar product for the
same indication at any time if:

● the second applicant can establish that its product, although similar, is safer, more effective or otherwise clinically superior;
● the marketing authorization holder for the authorized orphan product consents to a second orphan medicinal product application; or
● the marketing authorization holder for the authorized orphan product cannot supply enough orphan medicinal product.

The aforementioned European Union rules are generally applicable in the European Economic Area, which consists of the European Union Member States,
plus Norway, Liechtenstein and Iceland.

On  June  23,  2016,  the  electorate  in  the  United  Kingdom  voted  in  favor  of  leaving  the  European  Union,  commonly  referred  to  as  Brexit,  and  the  UK
formally left the European Union on January 31, 2020. There was a transition period during which European Union pharmaceutical laws continued to apply
to  the  United  Kingdom,  which  expired  on  December  31,  2020.  However,  the  European  Union  and  the  United  Kingdom  have  concluded  a  trade  and
cooperation agreement, or TCA, which was provisionally applicable since January 1, 2021 and has been formally applicable since May 1, 2021. The TCA
includes  specific  provisions  concerning  pharmaceuticals,  which  include  the  mutual  recognition  of  GMP,  inspections  of  manufacturing  facilities  for
medicinal  products  and  GMP  documents  issued,  but  does  not  foresee  wholesale  mutual  recognition  of  United  Kingdom  and  European  Union
pharmaceutical  regulations.  At  present,  Great  Britain  has  implemented  European  Union  legislation  on  the  marketing,  promotion  and  sale  of  medicinal
products through the Human Medicines Regulations 2012 (as amended) (under the Northern Ireland Protocol, the European Union regulatory framework
will  continue  to  apply  in  Northern  Ireland).  The  regulatory  regime  in  Great  Britain  therefore  broadly  aligns  with  current  European  Union  regulations,
however it is possible that these regimes will diverge in future now that Great Britain’s regulatory system is independent from the European Union and the
TCA does not provide for mutual recognition of United Kingdom and European Union pharmaceutical legislation.

If  we  fail  to  comply  with  applicable  foreign  regulatory  requirements,  we  may  be  subject  to,  among  other  things,  fines,  suspension  or  withdrawal  of
regulatory approvals, product recalls, seizure of products, operating restrictions and criminal prosecution.

Intellectual Property

Our success depends, at least in part, on our ability to protect our proprietary technology and intellectual property, and to operate without infringing or
violating the proprietary rights of others. We rely on a combination of patent, trademark, trade secret and copyright laws, know-how, intellectual property
licenses and other contractual rights, including confidentiality and invention assignment agreements to protect our intellectual property rights.

See  “Item  3.  Key  Information-D.  Risk  Factors-Risks  Related  to  Our  Intellectual  Property”  for  additional  discussion  on  our  intellectual  property  and
associated risks.

Patents

As  of  January  2022,  we  have  more  than  200  granted  patents  and  45  applications  pending  worldwide  for  our  oncology  program  and  VTS  platform
technology. Our lead VTS asset, ofra-vec, is covered by a US granted patent with an expiration date in 2033, prior to any patent term extension. We also
have  pending  patent  applications  covering  ofra-vec  diagnostic  methods,  the  use  of  ofra-vec  for  enhancing  antitumor  immune  responses,  and  ofra-vec
combination therapy with immune checkpoint inhibitors that, if granted, may extend protection into 2040. We also have more than 25 granted patents and
more than 25 applications pending worldwide for our VB-601 program and the MTT.

Trademarks

We rely on trade names, trademarks and service marks to protect our name brands. Our trademarks and registered trademarks in several countries include
the  following:  “VTS,”  “VBL  THERAPEUTICS,”  “VASCULAR  TARGETING  SYSTEM  VTS,”  “VBL,”  “V  VBL  THERAPEUTICS  &  Design,”
“VASCULAR BIOGENICS,” “VASCULAR THERAPEUTICS,” “V & Design,” “GLOBE & Design,” and “OVAL & Design”.

Trade Secrets and Confidential Information

In addition to patented technology, we rely on our unpatented proprietary technology, trade secrets, processes and know-how. We rely on, among other
things, confidentiality and invention assignment agreements to protect our proprietary know-how and other intellectual property that may not be patentable,
or  that  we  believe  is  best  protected  by  means  that  do  not  require  public  disclosure.  For  example,  we  require  our  employees  to  execute  confidentiality
agreements  in  connection  with  their  employment  relationships  with  us,  and  to  disclose  and  assign  to  us  inventions  conceived  in  connection  with  their
services to us. However, there can be no assurance that these agreements will be enforceable or that they will provide us with adequate protection.

We may be unable to obtain, maintain and protect the intellectual property rights necessary to conduct our business, and may be subject to claims that we
infringe or otherwise violate the intellectual property rights of others, which could materially harm our business. For a more comprehensive summary of
the risks related to our intellectual property, see “Item 3. Key Information-D. Risk Factors “

Sales and Marketing

We have not yet established sales, marketing or product distribution operations because our lead candidates are still in clinical development. We recently
appointed  a  Chief  Commercial  Officer  and  we  intend  to  expand  our  pre-commercialization  activities  as  we  prepare  for  the  readout  of  the  PFS  primary
endpoint from our Phase 3 OVAL trial in the second half of 2022 which we believe has the potential to support a BLA filing and, if approved, subsequent
commercialization.

Manufacturing

We  currently  perform  process  development,  characterization  and  manufacturing  for  our  lead  candidate  ofra-vec  in-house.  We  rely  on  third-party
manufacturers  to  manufacture  drug  supplies  for  other  drug  candidates.  We  also  contract  with  additional  third  parties  for  the  formulating,  labeling,
packaging, storage and distribution of the final drug products.

Until  late  2017,  we  manufactured  the  active  pharmaceutical  ingredient  and  the  formulated  drug  product  of  ofra-vec  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. We expect this plant to be the commercial
facility for production of our lead product candidate, ofra-vec, if approved. The Modi’in facility is a commercial-scale gene therapy manufacturing facility
in  Israel  (20,000  sq.  ft.).  The  site  design  enables  modular  expansion  of  the  manufacturing  capacity,  to  supply  growing  demand  following
commercialization. We believe the Modi’in facility will also enable us to comply with the Research Law and our undertaking to the OCS that an essential
portion of our ofra-vec production, and in any event not less than the majority, will remain in Israel. In July 2019, our facility was certified by a EU QP as
being in compliance with EU GMP. In November 2019 our facility was awarded by the Israeli Ministry of Health the Certificate of GMP Compliance of a
Manufacturer. Ofra-vec batches produced in our commercial-scale facility were authorized by the FDA for use in our clinical trials in the United States.

Employees

As of March 1, 2022, we employed 41 employees, including 30 in research and development, and 11 in general and administrative positions, and of which
12 employees have either M.D.s or Ph.D.s. 39 of our employees are located in Israel and 2 in the U.S. 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.

factors, including those discussed under “Item 3. Key Information-D. Risk Factors” and elsewhere in this Annual Report.

The audited financial statements for the years ended December 31, 2021, 2020 and 2019 and as of December 31, 2021 and 2020 in this Annual Report
have been prepared in accordance with U.S. GAAP.

Overview

We are a clinical stage biopharmaceutical company committed to developing next-generation, targeted medicines for difficult-to-treat medical conditions.
Using our novel platform technologies, we have created a pipeline of therapeutics to uniquely address cancer and immune-inflammatory diseases with the
goal of significantly improving patient outcomes and overcoming the limitations of currently approved treatments.

Our product candidates are built off of our two platform technologies: VTS, a gene-based technology targeting newly formed blood vessels, and Monocyte
Targeting Technology, or MTT, an antibody-based technology able to specifically inhibit monocyte migration for immune-inflammatory applications.

We  are  currently  evaluating  our  lead  candidate,  ofra-vec,  in  a  Phase  3  registration-enabling  trial  in  platinum  resistant  ovarian  cancer,  for  which  we
anticipate PFS primary endpoint data in the second half of 2022. We are also supporting Phase 2 trials in rGBM and metastatic colorectal cancer, or mCRC,
where  we  expect  preliminary  data  in  2022.  Our  second  program,  VB-601,  is  an  investigational  proprietary  monoclonal  antibody  that  binds  MOSPD2,
which  we  call  the  “mono-walk”  receptor,  and  is  engineered  to  specifically  prevent  monocytes  from  exiting  the  blood  stream  and  traveling  to  inflamed
tissues, and is expected to begin a first-in-human clinical trial in the second half of 2022.

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 platform technologies and our product candidates, including conducting preclinical studies and clinical trials of ofra-vec and VB-601, and
programs we are no longer pursuing. To date, we have funded our operations through private sales of preferred shares, a convertible loan, public offerings,
revenues  from  licensing  agreements  and  grants  from  the  Israeli  Office  of  Chief  Scientist,  or  OCS,  which  has  later  transformed  to  the  IIA  under  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 through December 31, 2021, we had raised an aggregate of $325.7 million to fund our operations, including $29.2 million
from IIA grants.

Since inception, we have incurred significant losses. For the years ended December 31, 2021, 2020 and 2019, our loss was $29.9 million, $24.2 million and
$19.4 million, respectively. We expect to continue to incur significant expenses and losses for at least the next several years and increased expenses related
to  our  development  programs,  including  expenses  related  to  pre-commercialization  activities  for  ofra-vec  and  the  initiation  of  new  clinical  trials.  As  of
December  31,  2021,  we  had  an  accumulated  deficit  of  $262.1  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, 2021, we had cash, cash equivalents, short-term bank deposits and restricted bank deposits of $53.5 million. To fund further operations
and obtain regulatory approval for our product candidates we may need to raise additional capital, and we will require additional capital to commercialize
and market any products that receive regulatory approval, including full pre-commercialization activities. We may seek to raise 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, 2022, we had 41 employees.

Financial Overview

Revenues and Cost of Revenues

Since inception, we generated cumulative revenues of approximately $16.7 million primarily from an exclusive license agreements for the development,
commercialization,  and  supply  of  ofra-vec  in  Japan  for  all  indications.  The  generated  revenues  comprise  upfront  and  milestone  payments.  The  cost  of
revenues associated with these payments was approximately $1.5 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 U.S.
GAAP, refer to Note 1.m. in the Notes to the Financial Statements.

Research and Development Expenses

Research and development expenses consist of costs incurred for the development of our platform technologies and 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 manufacturing facility;

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

● expenses related 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 ofra-vec 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-601 product candidate into clinical development.

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, 2021, 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 technology. 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  ofra-vec.  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 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  interest  as  of  December  31,  2021  and  2020,  totaled  $37.6  million  and  $36.0  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 counsel 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 have carry forward tax losses as of December 31, 2021 of $222.0 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.

We recognize a full valuation allowance because 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  U.S.  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

The recognition of revenue under our November 2017 license agreement with NanoCarrier requires the exercise of judgment by management. Notably, our
management exercises judgment in the following areas:

Identifying the performance obligations in the agreement and determining whether the license provided is distinct - based on our 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 - we estimated the standalone selling prices of the services to be provided based on expected cost plus margin and used
the residual approach to estimate the standalone selling price of the license as we have 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. We determined that all such variable consideration shall be allocated to the license
(the satisfied performance obligation).

Table of Contents 

Share-Based Compensation

With respect to grants to employees, the value is measured on the date of grant based on the fair value of the equity instruments granted to the employees.
We determine grant date fair value using the Black-Scholes model, which requires the management to make significant estimates and judgments. See Note
9 in the Notes to the Financial Statements for information regarding the various assumptions used.

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 our equity (see also Note 9 in the Notes to the Financial Statements).

Clinical trial accruals

Clinical trial expenses are charged to research and development expense as incurred. We accrue for expenses resulting from obligations under contracts
with 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. We reflect 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, 2021, we had approximately $1.9 million of clinical
trial accruals.

Lease

Under applicable accounting rules, accounting for our leases require the exercise of significant judgment and estimates by management. We recognize a
liability at the present value of the lease payments to be made over the lease term, and concurrently recognize a right of use, or 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. Determination of the
lease  term  by  management  requires  the  exercise  of  significant  judgment  and  estimates.  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 the 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 Notes 1.p and 5 in the Notes to the Financial Statements).

Revenues for the year ended December 31, 2021 were $0.8 million, compared to $0.9 million for the year ended in 2020 and $0.6 million for the year
ended December 31, 2019, a decrease of $0.1 million and an increase of $0.4 million, respectively.

Cost of revenues for the year ended December 31, 2021 were $0.4 million compared to $0.4 million for the year ended in 2020 and $0.2 million for the
year ended December 31, 2019. 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 presented net of IIA grants. Research and development expenses, net, for the year ended December 31, 2021 were
$22.7 million, compared to $19.7 million for the year ended December 31, 2020 and $14.7 million for the year ended December 31, 2019, an increase of
$3.0 million and an increase of $4.9 million, respectively.

The increase in research and development expenses, net, in 2021 was mainly related to the increase in activity in the Phase 3 OVAL trial and ofra-vec CMC
development  towards  anticipated  BLA  submission  of  approximately  $2.0  million  and  a  decrease  of  $1.0  million  in  the  IIA  grants  received  in  2021
compared to 2020.

The increase in research and development expenses, net, in 2020 was comprised of an increase of VB-601 development and Phase 3 clinical trial 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.

General and administrative expenses

General and administrative expenses for the year ended December 31, 2021 were $7.7 million, compared to $5.4 million for the year ended December 31,
2020 and $5.7 million for the year ended December 31, 2019, an increase of $2.3 million, and a decrease of $0.4 million, respectively.

This increase in 2021 is mainly attributed to higher premium costs for our directors’ and officers’ insurance, share-based compensation expense and U.S.
operational and professional costs compared to 2020.

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

Financial expense (income), net

Financial expense (income), net for the year ended December 31, 2021 was $0.1 million, compared to $0.3 million for the year ended December 31, 2020,
and $0.7 million for the year ended December 31, 2019, a decrease of $0.2 million in income, and a decrease of $0.4 million in income, respectively. The
decrease in 2021 in mainly due to lower interest income compared to 2020, and the decrease in 2020 is mainly due lower interest income compared to
2019.

Liquidity, Capital Resources, and Financial Requirements

Since our inception and through December 31, 2021, we have raised an aggregate of $325.7 million to fund our operations, including $29.2 million from
IIA grants. 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  our  previous  offerings,  to  advance  clinical
programs, working capital, certain pre-commercialization activities, and other general corporate purposes.

During  the  year  ended  December  31,  2021,  we  received  $26.4  million  in  net  proceeds  from  the  sale  of  ordinary  shares  and  pre-funded  warrants  in  an
underwritten  public  offering  and  an  aggregate  of  $23.1  million  in  gross  proceeds  from  warrant  exercises,  sales  under  our  at-the-market  facility  with
Oppenheimer & Co. Inc., or the Oppenheimer ATM, and direct shares sales under the ordinary share purchase agreement.

On  February  11,  2022,  we  terminated  the  Oppenheimer ATM  and  entered  into  the  Jefferies  ATM  pursuant  to  an  Open  Market  Sale  AgreementSM with
Jefferies  LLC  or  Jefferies,  providing  for  the  offer  and  sale  from  time  to  time  of  our  ordinary  shares  having  an  aggregate  offering  price  of  up  to  $50.0
million.

On December 31, 2021, we had cash, cash equivalents, short-term bank deposits and restricted bank deposits of $53.5 million and working capital of $44.9
million. We expect that our cash and cash equivalents and short-term bank deposits would provide sufficient funding for our current operating plans for at
least the next twelve months from the date of the readout of top-line PFS data from the Phase 3 OVAL trial (data we anticipate receiving in the second half
of  2022).  We  are  unable  to  estimate  the  amounts  of  increased  capital  outlays  and  operating  expenses  associated  with  completing  the  development  and
commercialization, if approved, of ofra-vec and our other product candidates. Our future capital requirements will depend on many factors, including:

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

● the costs of future development activities, including clinical trials, for ofra-vec, VB-601, and any other product candidates we may pursue;

● the costs of pre-commercialization and commercialization activities for ofra-vec, if approved;

● 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.  In  any  event,  we  might  require  additional  capital  to  obtain  regulatory
approval  for  our  product  candidates,  and  we  will  require  additional  capital  to  commercialize  and  market  any  products  that  receive  regulatory  approval,
including full pre-commercialization activities. We do not currently 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 ofra-vec and any other product candidates that we would otherwise
prefer to develop and market ourselves.

Cash Flows

The following table sets forth the primary sources and uses of cash for each of the periods set forth below:

Cash used in operating activities

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 nine directors. Following our adoption of certain reliefs provided under the Companies Law,
we are 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.

Upon  the  adoption  of  our  amended  and  restated  articles  of  association  upon  the  closing  of  our  IPO,  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  U.S.  domestic  companies  with  respect  to  the  appointment  of  independent  directors.  As  long  as  we  follow  these
requirements, 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  Dror
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.  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 U.S. domestic companies with respect to the
financial expertise of the directors. The exemption applies as long as we have no controlling shareholder, are in compliance with applicable U.S. law and
regulations and comply with the Nasdaq rules applicable to U.S. 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 U.S. domestic companies with respect to the
appointment of independent directors. The exemption applies as long as we have no controlling shareholder, are in compliance with applicable U.S. law
and regulations and comply with the Nasdaq rules applicable to U.S. 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 Marc Kozin to serve as chairman of the board of directors.

Committees of the Board of Directors

We  have  the  following  statutory  required  committees:  an  audit  committee,  a  compensation  committee  and  a  nomination  and  corporate  governance
committee. We have adopted a charter for each of these committees. In addition, we also have commercialization, business, and scientific 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 U.S. 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 David Hastings,
Ruth Alon and 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  SEC  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 SEC
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 Marc Kozin, Shmuel (Muli) Ben-Zvi, and Michael Rice. Mr. Kozin 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  U.S.  domestic  companies  with  respect  to  the  appointment  and
composition of the compensation committee.

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  and  on  October  19,  2021,  our  shareholders  approved  our  New  Compensation  Scheme,  and  described  in  “Item  6:
Compensation of Executive Officers, Key Employees, and Directors.”

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

Our nominating and corporate governance committee consists of Bennett Shapiro, Marc Kozin, and Ruth Alon and is chaired by Mr. Kozin. Each of the
members of our nominating and corporate governance committee 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:

● overseeing and assisting our board in reviewing and recommending nominees for election as directors;

● 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.

Scientific Committee

Our  scientific  committee  consists  of  Bennett  Shapiro,  Ron  Cohen,  Allison  Finger,  Dror  Harats  and  Ruth  Arnon  as  an  advisor  to  the  committee,  and  is
chaired by Dr. Shapiro.

Commercial and Business Committee

Our commercial and business committee consists of Allison Finger, Marc Kozin and Ron Cohen, and is chaired by Ms. Finger.

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 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

● a member of the company’s independent accounting firm, or anyone on its behalf.

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, Senior Management and Directors” and management members of at least a VP level are considered 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, Key Employees, and Directors

We have entered into written employment agreements with Dror Harats and other senior members of management located in Israel. 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  or  key  employee’s  employment.  In  addition,  we  are  required  to  provide  notice  of
between three and nine months prior to terminating their employment 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 breach by Prof. Harats’s of any of the material terms or conditions of his employment
agreement; Prof. Harats’s conviction of any crime involving moral turpitude or dishonesty or the commission of a criminal offense, or fraud against us or
any of our subsidiaries or affiliates; Prof. Harats’s willful refusal to perform the lawful instructions of our board of directors pertaining to the Prof. Harats’
employment under his employment agreement; any breach of Prof. Harats’s fiduciary duties or duties of care to our company or any of our subsidiaries or
affiliates (except for conduct taken in good faith); any conduct (other than conduct in good faith) materially detrimental to us or any of our subsidiaries or
affiliates; or circumstances that deny Prof. Harats to severance payment under any applicable law or under any judicial decision of a competent tribunal
authority.  Pursuant  to  his  employment  agreement,  “Good  reason”  means  a  material  reduction  in  Prof.  Harats’s  duties,  responsibilities  or  authority,  a
material  reduction  in  Prof.  Harats’s  overall  compensation  package  which  is  not  part  of  a  policy  pursuant  to  which  the  salary  of  all  of  our  other  senior
officers is reduced in a comparable manner, a material breach by us of any provision of Prof. Harats’s employment agreement, or if Prof. Harats resigns
when such resignation is considered as a discharge or constructive dismissal which entitles him to severance payment under Israeli law.

We have also entered into written employment agreements and Employee Confidentiality, Assignment, Non-solicitation and Non-competition Agreements,
or the Confidentiality Agreements, through our wholly owned U.S. subsidiary, VBL Inc., with Sam Backenroth as Chief Financial Officer and Matthew
Trudeau as Chief Commercial Officer. Both Confidentiality Agreements contain provisions regarding non-competition, confidentiality of information and
assignment of inventions. The non-competition provisions apply for a period of 12 months following the last day of employment of the respective officer.
Under  certain  conditions,  these  employment  agreements  provide  for  benefits  upon  the  termination  of  these  executives’  respective  employment  with  us,
other than payment of salary and benefits. Such benefits include (i) continuation of the base salary as of the date of termination for the 12-month period in
Mr. Backenroth’s case and nine months in Mr. Trudeau’s case; (ii) continuation of group health plan benefits under certain terms; and (iii) any vested equity
rights and vested retirement benefits, if any, to which such officers may be entitled under our employee benefit plans as of the termination date.

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 February 1, 2022, we employed 41 employees, including 30 in research and development, and 11 in general and administrative positions, and of
which  12  employees  have  either  M.D.s  or  Ph.D.s.  39  of  our  employees  are  located  in  Israel  and  two  are  located  in  the  United  States.  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- Significant Shareholders.”

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  2022  Inducement  Plan  allows  us  to  grant  options  to  purchase  our  ordinary  shares  to  new  hires  in  the  U.S.A,  upon
recruitment. 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.

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.

Inducement Plan (2022)

On January 27, 2022, our board of directors adopted the Vascular Biogenic Ltd. Inducement Plan (2022), or the Inducement Plan. The purpose and intent of
the Inducement Plan is to enable us to grant equity awards to induce highly qualified prospective officers and employees who are Eligible Employees to
accept  employment  and  to  provide  them  with  a  proprietary  interest  in  our  company,  pursuant  to  Rule  5635(c)(4)  or  5635(c)(3),  if  applicable,  of  the
Marketplace Rules of the Nasdaq and the related guidance under Nasdaq IM 5635-1. An “Eligible Employee” under the Inducement Plan is an individual
who was not previously an employee or a non-employee director or of any of our affiliates (or who has had a bona fide period of non-employment), who is
hired as a full or part-time employee by us or one of our affiliates.

The maximum number of shares that may be issued under the Inducement Plan is 2,000,000 of our ordinary shares, and the types of awards that may be
granted under the Inducement Plan, are: nonqualified options, restricted shares; RSU awards and other share or share-based awards

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.

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,  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.

Prior to January 2022, 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 quarterly thereafter for three years such that vested in full on the four-year anniversary of the grant date. Beginning
January  2022,  options  granted  under  the  2014  Plan  generally  vest  over  three  years  commencing  on  the  date  of  grant  such  that  25%  vest  on  the  first
anniversary of the date of grant and then quarterly thereafter for two years, such that it is vested in full on the three-year anniversary of the grant date.
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. 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 20 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 20 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.

Table of Contents 

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 March 1, 2022:

● 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 March 1, 2022 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
69,337,312 ordinary shares outstanding as of March 1, 2022.

According to our transfer agent, as of March 1, 2022, there were 12 record holders of our ordinary shares, of which three record holders were located in the
United States. None of our shareholders have 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.

Family Trust and the 2008 Trust. As a result of the Lee Beneficial Ownership Limitation, the number of shares that may be issued to Ms. Lee upon
exercise of the warrant may change depending upon changes in the number of our outstanding ordinary shares and accordingly, not all 7,400,000 pre-
funded warrants may be exercised at this time. The principal business address of Ms. Lee is 70 Rainey Street, Austin, Texas 78701. The address of the

In December 2021, pursuant to the review and approval of the audit committee, we entered into an investor relations services agreement with an affiliate of
one of our directors. The term of the agreement is six months, automatically renewed for additional 6 month terms unless otherwise terminated, and incurs
monthly fees of $20,000 plus third party expense reimbursement.

See  “Item  6  Directors,  Senior  Management  and  Employees—Approval  of  Related  Party  Transactions  Under  Israeli  Law”  for  more  information  on  the
approval process for these agreements.

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  “Item  6.  Directors,  Senior  Management  and
Employees-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.

81

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
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-Approval  of  Related  Party  Transactions  Under  Israeli  Law-  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, or the 2005 Amendment, and further amended as of January 1, 2011, or the 2011
Amendment, and as of January 1, 2017, or 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.

84

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
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, or 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).

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, or 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.

Table of Contents 

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 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 PFIC.

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  2021  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.”

Certain elections may potentially be used to reduce the adverse impact of the PFIC rules on U.S. Holders (“qualifying electing fund,” or 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. payer 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 payer 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. payer 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,  or  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 38%
of our expenses in 2021 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 2%.

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, 2020
Year ended December 31, 2019

Inflation Risk

%

3.27%
(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 our 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 our 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, 2021.

Item 16F. Change in Registrant’s Certifying Accountant

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.  Key
Information-D.  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.

Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying consolidated balance sheets of Vascular Biogenics Ltd. and its subsidiary (the “Company”) as of December 31, 2021
and 2020, and the related consolidated 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, 2021, including the related notes (collectively referred to as the “consolidated financial statements”). We also have
audited  the  Company’s  internal  control  over  financial  reporting  as  of  December  31,  2021,  based  on  criteria  established  in  Internal  Control  -  Integrated
Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of
December 31, 2021 and 2020, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2021 in
conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material
respects,  effective  internal  control  over  financial  reporting  as  of  December  31,  2021,  based  on  criteria  established  in  Internal  Control  -  Integrated
Framework (2013) issued by the COSO.

Basis for Opinions

The Company’s management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting,
and for its assessment of the effectiveness of internal control over financial reporting, included in Management’s Report on Internal Control over Financial
Reporting appearing under Item 15. Our responsibility is to express opinions on the Company’s consolidated financial statements and on the Company’s
internal control over financial reporting 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 in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable
assurance  about  whether  the  consolidated  financial  statements  are  free  of  material  misstatement,  whether  due  to  error  or  fraud,  and  whether  effective
internal control over financial reporting was maintained in all material respects.

Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated 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 consolidated 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 consolidated financial statements. Our audit of internal
control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness
exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing
such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting
and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control
over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly
reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit
preparation  of  financial  statements  in  accordance  with  generally  accepted  accounting  principles,  and  that  receipts  and  expenditures  of  the  company  are
being  made  only  in  accordance  with  authorizations  of  management  and  directors  of  the  company;  and  (iii)  provide  reasonable  assurance  regarding
prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial
statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of
effectiveness  to  future  periods  are  subject  to  the  risk  that  controls  may  become  inadequate  because  of  changes  in  conditions,  or  that  the  degree  of
compliance with the policies or procedures may deteriorate.

Critical Audit Matters

Critical audit matters are matters arising from the current period audit of the consolidated 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  consolidated  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

VBL  is  a  clinical  stage  biopharmaceutical  company  committed  to  developing  next-generation,  targeted  medicines  for  difficult-to-treat  medical
conditions. Using its novel platform technologies, VBL has created a pipeline of therapeutics to uniquely address cancer and immune-inflammatory
diseases with the goal of significantly improving patient outcomes and overcoming the limitations of currently approved treatments.

VBL’s  product  candidates  are  built  off  of  our  two  platform  technologies:  Vascular  Targeting  System  (VTS™),  a  gene-based  technology  targeting
newly  formed  blood  vessels,  and  Monocyte  Targeting  Technology  (MTT),  an  antibody-based  technology  able  to  specifically  inhibit  monocyte
migration for immune-inflammatory applications.

We are currently evaluating our lead candidate, ofra-vec, in a Phase 3 registration-enabling trial in platinum resistant ovarian cancer, for which we
anticipate PFS primary endpoint data in the second half of 2022. We are also supporting Phase 2 trials in rGBM and metastatic colorectal cancer, or
mCRC where we expect preliminary data in 2022. Our second program, VB-601, is an investigational proprietary monoclonal antibody that binds
MOSPD2, which we call the “mono-walk”, receptor, and is engineered to specifically prevent monocytes from exiting the blood stream and traveling
to inflamed tissues, and is expected to begin a first-in-human clinical trial in the second half of 2022.

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

Since inception, VBL 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, 2021, the Company had an accumulated deficit of $262.1 million. VBL’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,  2021,  the  Company  had  cash,  cash  equivalents,  short-term  bank  deposits  and  restricted  cash  of  $53.5 million.  Based  on  its
current cash resources, VBL believes its current cash will be sufficient to fund our operations for at least twelve months from the date of the filing of
these financial statements. VBL may seek to raise additional capital to pursue additional activities through a combination of private and public equity
offerings, government grants, strategic collaborations and licensing arrangements. Additional financing may not be available when VBL needs it or
may not be available on terms that are favorable to the Company.

In September 2021, the Company established VBL Inc., a U.S. based subsidiary of VBL, and began U.S. operations from this entity in the fourth
quarter of 2021.

On December 20, 2021, the Company announced that it was awarded €17.5 million of blended funding from the Horizon Europe Innovation Council
(EIC) Accelerator Program, which will be comprised of a €2.5 million grant and an additional €15 million direct equity investment by the EIC. The
award is subject to the terms of the program and entering into definitive documentation. The Company has not yet received this funding.

 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”).

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 and its U.S. subsidiary 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  all  short-term,  highly  liquid  investments,  to  be  a  cash  or  cash  equivalents,  which  includes  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  for  operating  lease  contractual  agreements  recorded  in  non-current
assets 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 recorded in the statement of comprehensive loss 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

NOTES TO THE FINANCIAL STATEMENTS (continued)

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, 2021, no impairment has been recognized.

h. Deferred income tax

Deferred taxes are recognized using the asset and 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
the Israel Severance Pay Law from the beginning of their employment with the Company.

With respect to the remaining employees, which are not covered by a defined contribution plan under Section 14 of the Israel Severance Pay
Law only from January 1, 2010, the Company records a liability in its balance sheet.

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 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.

The Company calculates the fair value of stock-based option awards on the date of grant using the Black-Scholes option pricing model. This option
pricing model requires estimates as to the option’s expected term and the price volatility of the underlying stock.

The Company measures compensation expense for the restricted stock units based on the market value of the underlying stock at the date of grant.

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, 2021, no contingent liabilities have been recognized.

NOTES TO THE FINANCIAL STATEMENTS (continued)

NOTE 1 – SIGNIFICANT ACCOUNTING POLICIES (continued):

 m. Revenue from contracts with customers:

General

The Company recognizes 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.

NOTE 1 – SIGNIFICANT ACCOUNTING POLICIES (continued):

 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, 2021, 2020 and 2019, include participation in research and development expenses in the amount of approximately $0.5
million, $1.4 million and $2.7 million, respectively.

p. Leases

The Company determines if an arrangement is a lease at inception. Balances related to  operating leases are included in operating lease right-of-use
(“ROU”) assets, other current  liabilities, and operating lease liabilities in the consolidated balance sheets.  

The Company also elected to combine lease and non-lease components and to keep leases  with an initial term of 12 months or less off the balance
sheet and recognize the associated  lease payments in the consolidated statements of income on a straight-line basis over the lease  term. 

ROU assets represent the Company’s right to use an underlying asset for the lease term, and  lease liabilities represent the Company’s obligation to
make lease payments arising from the  lease. Operating lease ROU assets and liabilities are recognized as of the commencement date  based on the
present  value  of  lease  payments  over  the  lease  term.  The  Company’s  lease  terms   may  include  options  to  extend  or  terminate  the  lease  when  it  is
reasonably certain that the  Company will exercise that option. The discount rate for the lease is the rate implicit in the  lease unless that rate cannot be
readily determined. As the Company’s leases do not provide an  implicit rate, the Company’s uses its estimated incremental borrowing rate based on
the   information  available  at  the  commencement  date  in  determining  the  present  value  of  lease   payments.  Lease  expense  for  lease  payments  is
recognized on a straight-line basis over the  lease term (see also note 5).

 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 has one operating segment.

 r. Loss per Ordinary Share

VBL complies with accounting and disclosure requirements of FASB ASC Topic 260, Earnings Per Share. Basic loss per share of common stock is
computed by dividing the net loss by the weighted average number of ordinary shares(including fully vested RSUs and PSUs) outstanding during the
period. Due to the existence of Ordinary shares subject to possible redemption, the Company follows the two-class method in calculating loss per
share. In computing diluted earnings per share, basic earnings per share are adjusted to take into account the potential dilution that could occur upon
the exercise of options and non-vested RSUs and PSUs, using the treasury stock method.

Accretion associated with the ordinary shares subject to possible redemption is excluded from loss per ordinary share.

Potentially dilutive securities have been excluded from VBL’s computation of dilutive loss per share as such securities would have been anti-dilutive.
There were 12,191,029, 23,264,073, 13,528,092 ordinary shares underlying outstanding options and warrants at December 31, 2021, 2020, and 2019,
respectively.

 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.

 t. Recently issued accounting pronouncements, not yet adopted  

In  November  2021,  the  FASB  issued  ASU  2021-10  “Government  Assistance  (Topic  832)”,  which  requires  annual  disclosures  that  increase  the
transparency of transactions involving government grants, including (1) the types of transactions, (2) the accounting for those transactions, and (3) the
effect of those transactions on an entity’s financial statements. The amendments in this update are effective for financial statements issued for annual
periods  beginning  after  December  15,  2021.  The  Company  is  currently  evaluating  this  guidance  to  determine  the  impact  it  may  have  on  its
consolidated financial statements.

NOTE 2 – FAIR VALUE MEASUREMENTS

The different levels of valuation of financial instruments are defined as follows:

Level 1

Level 2

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.

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, 2021, 2020 and 2019, the fair value of financial instruments (cash and cash equivalents, short term bank deposits, other current assets
and accounts payable) is approximate to their carrying value.

NOTE 3 – SHORT-TERM BANK DEPOSITS

The bank deposits in 2021 of $31.2 million are for terms of three months to one year and carry interest at annual rates of 0.65%-0.85%. The bank deposits
in 2020 of $17.1 million are for terms of three months to one year and carry interest at annual rates of 0.01%-0.75%.

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 through the 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  do  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  funds  under  Section  14  for  such  employees  is  recorded  on  the  Company’s  balance  sheet  as  the  Company  is
relieved of its obligation upon contribution.

For  certain  Israeli  employees,  the  Company  accrues  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 to employees’ rights upon retirement.

During  the  five-year  period  following  December  31,  2021,  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 $0.1 million.

The amounts of severance pay expenses were approximately $0.3 million, $0.2 million, and $0.2 million for each of the years ended December 31, 2021,
2020 and 2019, respectively, which were substantially made up of company payments to the Contribution Plans. Gains on amounts funded in respect of
employee rights upon retirement for the years ended December 31, 2021, 2020 and 2019 was immaterial.

The  Company  expects  to  contribute  approximately  $0.3 million  in  the  year  ending  December  31,  2022  to  insurance  companies  in  connection  with  its
severance liabilities for its operations for that year, approximately all 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.

NOTE 7 – LICENSE AND SUPPLY AGREEMENTS

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

In November 2017, the Company signed an exclusive license agreement with NanoCarrier Co., Ltd. for the development, commercialization, and supply of
ofra-vec in Japan. VBL retains rights to ofra-vec globally except for Japan (“The License Agreement”). Under the terms of the agreement, VBL has granted
NanoCarrier  an  exclusive  license  to  develop  and  commercialize  ofra-vec  in  Japan  for  all  indications.  VBL  will  supply  NanoCarrier  with  ofra-vec,  and
NanoCarrier  will  be  responsible  for  all  regulatory  and  other  clinical  activities  necessary  for  commercialization  in  Japan.  In  exchange,  the  Company
received  an  up-front  nonrefundable  payment  of  $15.0  million,  and  is  entitled  to  receive  greater  than  $100.0  million  in  additional  payments  if  certain
development  and  commercial  milestones  are  achieved.  VBL  will  also  receive  tiered  royalties  on  net  sales.  In  addition,  if  NanoCarrier  enters  into  a
sublicense agreement, the Company would be entitled to receive royalties from the sublicense income received by NanoCarrier.

In March 2019, the Company entered into exclusive option license agreement (hereafter- Agreement) with an animal health company, for the development
of  VB-201  for  veterinary  use.  Under  the  Agreement,  the  Company  granted  a  right  to  use  intellectual  property  and  transfer  materials.  In  addition,  the
Company granted an option to obtain an exclusive worldwide, royalty-bearing, transferable license under the Company’s intellectual property and materials
to research, develop and sell the product worldwide.

As part of the Agreement, the Company received an immaterial non-refundable and non-creditable upfront payment recognized as revenues during 2019.
In addition, the Company is entitled to receive an immaterial amount upon the achievement of a milestone event.

The performance obligation relating to the Company’s participation and consulting assistance services during the development period is recognized over
the service period. During 2021, 2020 and 2019 the Company recognized revenue in an amount of $0.8 million, $0.9 million and $0.6 million, respectively
related to the Company’s participation and consulting assistance services of ofra-vec in Japan for all indications and from the option to license agreement
for the development of VB-201 for animal healthcare worldwide. Out of the consideration received in the License Agreement, as of December 31, 2021,
the Company has deferred revenue in the amount of $0.7 million in 2021 that is classified within current liabilities.

Revenues recognized in 2021, 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.  All  of  revenues  recognized  in  2021  were
included in the opening balance of the deferred revenue in the balance sheets.

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
comprehensive loss under research and development costs.

Through December 31, 2021, the Company paid Tel Hashomer a total amount of $0.7 million 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 funded
up to 100% of the amount of the grant received by the Company (dollar linked) with the addition of an annual interest. As of December 31, 2021, the
total  additional  royalty  amount  that  may  be  payable  by  the  Company,  before  the  additional  interest,  is  approximately  $29.2  million  ($37.6  million
including interest). To date, the Company has paid the IIA approximately $0.6 million in royalties.

NOTE 8 – COMMITMENTS (continued):

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

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.

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, 2021, the Company sold an aggregate of 1,285,366 ordinary shares under its at-the-market (“ATM”)
equity facility. The total gross consideration amounted to approximately $3.5 million.

The  Company  failed  to  file  a  prospectus  supplement  specifying  details  of  the  share  sales  under  the  ATM. This  may  have  constituted  a  violation  of
Section 5 of the U.S. Securities Act of 1933, as amended (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 VBL would be obligated to
repay would be approximately $3.5 million, plus interest. Out of the approximately $3.5 million of sales, one identified buyer purchased approximately
$1.9 million of the Company’s ordinary shares. Such identified buyer has agreed to waive any rescission rights and has signed a waiver evidencing
such agreement. 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,  VBL  may  become  subject  to  fines  and
penalties  imposed  by  the  SEC  and  state  securities  agencies.  Based  on  consultation  with  its  counsel  and  management  assessment,  VBL  did  not
recognize any provision related to this uncertainty.

VBL  analyzed  the  classification  of  the  ordinary  shares.  Based  on  ASC  480-10-S99-3A(f),  VBL  determined  that  since  the  redemption  obligation  is
outside of its control, the ordinary shares should be considered ordinary shares subject to possible redemption, and $1.6 million should classified as
temporary equity as ordinary shares subject to possible redemption, as reflected in the balance sheet, see also note 13.

b. 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 remains 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 was 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 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,  2021,  all  11,492,065  warrants  issued  pursuant  to  these  securities  purchase  agreements  were  exercised  for  gross  proceeds  of
approximately $16.7 million.

c. On July 29, 2020, at the general meeting of the shareholders of the Company, such shareholders approved the increase of the authorized share capital

of the Company to 150,000,000 ordinary shares, par value NIS 0.01 per share.

d. On January 14, 2021, the Company entered into an ordinary share purchase agreement (Agreement) of up to $20 million of VBL’s ordinary shares, par
value NIS 0.01 per share, with an institutional investor. The ordinary shares may be sold from time to time based on our notice to the investor over the
30-month term of the purchase Agreement. As of December 31, 2021, the Company issued 1,400,000 shares under the Agreement for gross proceeds
of approximately $3.0 million.

e. On April 9, 2021, VBL entered into an underwriting agreement pursuant to which the Company issued(a) 5,150,265 of its ordinary shares to certain
investors at a price of $1.90 per ordinary share and (b) pre-funded warrants to purchase 8,050,000 ordinary shares at price of $1.89  per  pre-funded
warrant  with  an  exercise  price  of  each  pre-funded  warrant  equal  to  $0.01  per  share.  In  addition,  the  underwriters  exercised  an  option  to  purchase
additional shares and purchased 1,751,525 additional ordinary shares. Net proceeds from the issuance and sale of the 6,901,790 ordinary shares and
8,050,000  pre-funded  warrants  was  approximately  $26.4  million,  after  deducting  the  underwriting  discounts  and  commissions  and  the  estimated
offering expenses.

f. On May 6, 2021, 1,250,000 five year warrants issued in the Company’s November 6, 2015 registered direct offering expired.

g. 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
provides  the  holder  the  right  to  exercise  such  option  and  acquire  one  Ordinary  Share  per  option.  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 option grants are 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.

NOTES TO THE FINANCIAL STATEMENTS (continued)

Most of the options granted in 2019, 2020, and 2021 vest over 4 years with 25% vesting on the first anniversary and the remainder vesting quarterly over
the next 3 years. The remaining 327,681 options granted in fiscal 2021 vest over 2 years with 50% on the first-anniversary, and the remaining 50% vesting
equally at the end of each quarter in the second year.

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  granted  for  the  years  ended  December  31,  2021,  2020  and  2019  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, 2021, 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, 2021, 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.

d. Losses for tax purposes carried forward to future years

The balance of carry forward losses of the Company as of December 31, 2021 is $222.0 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 2016.

f. Deferred Taxes

The  following  table  presents  summary  of  information  concerning  the  Company’s  deferred  taxes  as  of  the  periods  ending  December  31,  2021  and

DESCRIPTION OF SECURITIES

Exhibit 2.3

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.

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.
