**INTRODUCTION**

We are a regenerative and aesthetic medicine company focused on 3D bioprinting of tissues and organs, and medical aesthetics. Our products are based on our recombinant human collagen, or rhCollagen, that is produced with our proprietary plant based genetic engineering technology. Our products address indications for the diverse fields of tissue repair, aesthetics and organ manufacturing, and, we believe, are ushering in a new era in regenerative and aesthetic medicine. Our collaborations include, among others, AbbVie, STEMCELL, Tel Aviv University, Sheba Medical Center, the Advanced Regenerative Manufacturing Institute, or ARMI, and the RegenMed Development Organization, or ReMDO.

Our flagship rhCollagen BioInk product line is ideal for 3D bioprinting of tissues and organs. We are developing 3D bioprinted breast implants for regeneration of breast tissue and aim to provide a revolutionary alternative to the current practices. The implants in development will be bioprinted and loaded with compositions that are based on rhCollagen and extracellular matrix, or ECM, components. These implants are intended to promote tissue regeneration and degrade in synchronization with the development of a natural breast tissue.

In February 2021, we entered into a Development, Exclusivity and Option Products Agreement with AbbVie Inc., or AbbVie, pursuant to which we and AbbVie will collaborate in the development and commercialization of dermal and soft tissue filler products for the medical aesthetics market, using our rhCollagen technology and AbbVie's technology. To date, the development of the product continues to move forward according to plan.

In October 2021, we announced that our rhCollagen based Bioink was used successfully by researchers from Israel's Technion Institute of Technology to create a 3D bioprinted implantable tissue containing a network of blood vessels capable of supplying blood to the implanted tissue.

In November 2022 we launched Collink.3D 90, an rhCollagen-based bioink solution for use in a variety of 3D bioprinting applications, offering increased mechanical properties to address additional printing requirements of soft and hard tissues. Collink.3D™ 90 is complementary to our first commercial bioink, Collink.3D 50, which was launched in November 2021, for use in 3D bioprinting. Collink.3D 50, our first commercially available rhCollagen-based bioink product is designed to allow the scalable and reproduceable biofabrication of scaffolds, tissues and organ transplants. Made entirely from human-derived collagen, Collink.3D bioinks enables the production of scaffolds that accurately mimic the physical properties of human tissues and organs, with improved bio-functionality, safety and reproducibility.

Also in November 2022, we entered into a license and research agreement with Tel Aviv University and Sheba Medical Center hospital, to co-develop a 'Gut-on-a-Chip' tissue model for drug discovery and high throughput screening of drugs. The model is intended to be used in personal medicine applications for the treatment of ulcerative colitis, an inflammatory bowel disease affecting millions of individuals worldwide.

iii

In January 2023, we launched Collink.3D™ 50L in powder form, which is our first bioink available in powder form and provides enhanced operational flexibility to support a wide range of 3D bioprinting applications, including drug discovery, drug screening, tissue testing as well as the development of transplantable tissues and organs.

Previously, in December 2020, we entered into a product manufacturing and supply agreement with STEMCELL. As part of the agreement, we are selling our proprietary recombinant human Type I collagen (rhCollagen) to STEMCELL, which incorporates our product into cell culture media kits. To date, hundreds of companies, as well as research and academic institutes, have used these kits for research and development projects. STEMCELL is distributing the kits globally for use in the regenerative medicine research market.

On May 25, 2021, our ordinary shares were approved for trading on the Nasdaq Global Market and began trading at the open of market on June 4, 2021. At such time, our American Depositary Shares, or ADSs, each representing one ordinary shares, were mandatorily cancelled and exchanged for ordinary shares at a one-for-one ratio. Prior to that, our ADSs were quoted on the OTCQX from March 2015 to May 25, 2017, on the OTCQB from May 26, 2017 to January 30, 2018 and on the Nasdaq Capital Market from January 31, 2018 to June 3, 2018 under the symbol "CLGN". In 2018, we delisted our ordinary shares from trading on the Tel Aviv Stock Exchange, or TASE, and the last date of trading of our ordinary shares on the TASE was on October 29, 2018.

Unless the context requires otherwise, the terms "CollPlant," "we," "us," "our," "the Company," and similar designations refer to CollPlant Biotechnologies Ltd. and its subsidiaries, CollPlant Ltd. and CollPlant Inc. References to "ordinary shares", "ADSs", "warrants" and "share capital" refer to our ordinary shares, ADSs, warrants and share capital, respectively, of CollPlant.

References to "U.S. dollars" and "$" are to currency of the United States of America, and references to "NIS" are to New Israeli Shekels. References to "ordinary shares" are to our ordinary shares, par value NIS 1.50 per share. We report financial information under generally accepted accounting principles in the United States of America or U.S. GAAP.

From the Company's inception through December 31, 2018, the Company's functional and presentation currency was NIS. Management conducted a review of the functional currency of the Company and decided to change its functional and presentation currency to the U.S. dollar from the NIS, effective January 1, 2019. This change was based on an assessment by Company management that the dollar is the primary currency of the economic environment in which the Company operates. Accordingly, the functional and presentation currency of the Company in this annual report on Form 20-F is the U.S. dollar.

Prior to the termination of our ADS program in June 2021, we effected a 1-for-50 reverse share split of our ordinary shares effective as of July 15, 2019. Concurrently with the reverse split, we effected a corresponding change in the ratio of ordinary shares to each of our ADSs, such that the ratio of ADSs to ordinary shares changed from one ADS representing 50 ordinary shares to a new ratio of one ADS representing one ordinary share. All share numbers in this annual report on Form 20-F are reflected on a post-reverse stock split basis and on a post-ADS termination program basis.

Readers are urged to carefully review and consider the various disclosures made throughout this Annual Report on Form 20-F which are designed to advise interested parties of the risks and factors that may affect our business, financial condition, results of operations and prospects.

You should not put undue reliance on any forward-looking statements. Any forward-looking statements in this annual report on Form 20-F are made as of the date hereof and are expressly qualified in their entirety by the cautionary statements included in this Annual Report. We undertake no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise, except as required by law.

In addition, the section of this Annual Report on Form 20-F entitled "Item 4. Information on the Company" contains information obtained from independent industry sources and other sources that we have not independently verified.

**EXPLANATORY NOTE**

Market data and certain industry data and forecasts used throughout this Annual Report on Form 20-F were obtained from internal company surveys, market research, consultant surveys commissioned by the Company, publicly available information, reports of governmental agencies and industry publications and surveys. Industry surveys, publications, consultant surveys commissioned by the Company and forecasts generally state that the information contained therein has been obtained from sources believed to be reliable. However, this information may prove to be inaccurate because of the method by which some of the data for the estimates is obtained or because this information cannot always be verified with complete certainty due to the limits on the availability and reliability of raw data, the voluntary nature of the data gathering process and other limitations and uncertainties. As a result, the market and industry data and forecasts included or incorporated by reference in this annual report, and estimates and beliefs based on that data, may not be reliable. We have relied on certain data from third-party sources, including internal surveys, industry forecasts and market research, which we believe to be reliable based on our management's knowledge of the industry. However, we have not ascertained the underlying economic assumptions relied upon therein. Forecasts are particularly likely to be inaccurate, especially over long periods of time. In addition, we do not necessarily know what assumptions regarding general economic growth were used in preparing the forecasts we cite. Statements as to our market position are based to the best of our knowledge on the most currently available data. While we are not aware of any misstatements regarding the industry data presented in this annual report, our estimates involve risks and uncertainties and are subject to change based on various factors, including those discussed under the heading "Risk Factors" in this Annual Report.

Statements made in this Annual Report on Form 20-F concerning the contents of any agreement, contract or other document are summaries of such agreements, contracts or documents and are not a complete description of all of their terms. If we filed any of these agreements, contracts or documents as exhibits to this Report or to any previous filing with the Securities and Exchange Commission, or SEC, you may read the document itself for a complete understanding of its terms.

**D.** **Risk Factors** 

You should carefully consider the risks described below, together with all of the other information in this Annual Report on Form 20-F. The risks and uncertainties described below are those significant risk factors, currently known and specific to us, that we believe are relevant to an investment in our securities. Additional risks and uncertainties not currently known to us or that we now deem immaterial may also harm us. If any of these risks materialize, our business, results of operations or financial condition could suffer, and the price of our ordinary shares could decline substantially.

**Summary Risk Factors**

Investing in our ordinary shares involves a high degree of risk, as fully described below. The principal factors and uncertainties that make investing in our ordinary shares risky, include, among others:

**Risks Related to Our Financial Position and Capital Requirements**

● Except for the year ended December 31, 2021, we have incurred significant losses since our inception and anticipate that we will continue to incur losses for the foreseeable future.

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

**Risks Related to Commercialization of Our Products**

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

● We have only limited clinical data to support sales of our products, which may make physicians, patients, third-party payors, and others in the medical community reluctant to accept or purchase our products.

● We have low scale experience in producing our rhCollagen, and if we are unable to manufacture our rhCollagen in high commercial quantities successfully and consistently to meet demand, our growth will be limited.

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

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

**Risks Related to the Clinical Development and Regulatory Approval of Our Products**

● We currently depend heavily on the future success of our BioInk and our medical aesthetics and 3D bioprinting product candidates. Any failure to successfully develop, obtain regulatory approval for, and commercialize these products or their end products, 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 products are based on novel technology, which makes it difficult to predict the time and cost of product development and potential regulatory approval.

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

● Future clinical trials may not be successful or may be delayed.

● Even if we or our strategic partners obtain regulatory approval for a product, our products will remain subject to regulatory scrutiny.

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

**Risks Related to Our Reliance on Third Parties**

● We may not be successful in establishing and maintaining strategic partnerships, which could adversely affect our ability to develop and commercialize our rhCollagen based BioInks and dermal fillers.

● We expect to depend upon third-party collaborators, distributors and resellers for a significant portion of our sales.

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

**Risks Related to Our Business Operations**

● Our future success depends on our ability to retain senior management, consultants, and advisors and to attract, retain, and motivate qualified personnel.

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

● Our business and operations would suffer in the event of computer system failures or security breaches.

● Our development and production of rhCollagen relies upon the continued availability of tobacco plants, and any interruption in availability or supply of tobacco plants may delay production and adversely affect commercial utilization of our rhCollagen-based products.

● If our existing rhCollagen production site or any new facility is damaged or destroyed, or production at this facility is otherwise interrupted, our business and prospects would be negatively affected.

● 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 impact on the success of our business.

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

● Our business may be adversely affected if there is a resurgence of the COVID-19 pandemic.

● Our business, operating results and growth rates may be adversely affected by current or future unfavorable economic and market conditions and adverse developments with respect to financial institutions and associated liquidity risk.

● Environmental, social and corporate governance (ESG) issues, including those related to climate change and sustainability, may have an adverse effect on our business, financial condition and results of operations and damage our reputation.

**Risks Related to Our Intellectual Property**

● We have an extensive worldwide patent portfolio. The cost of maintaining our patent protection is high and maintaining our patent protection requires continuous review and compliance in order to maintain worldwide patent protection. We may not be able to effectively maintain our intellectual property position throughout the major markets of the world.

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

**Risks Related to the Ownership of our Ordinary Shares**

● The market price of our ordinary shares may be highly volatile.

● We may not be able to maintain our listing on the Nasdaq Global Market.

● Our principal shareholders, management and directors beneficially own a significant percentage of our ordinary shares and will be able to exert significant influence over matters subject to shareholder approval.

● If we fail to maintain an effective system of internal control over financial reporting, we may not be able to accurately report our financial results or prevent fraud. As a result, our shareholders could lose confidence in our financial and other public reporting, which would harm our business and the trading price of our ordinary shares.

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

**Risks Related to Our Operations in Israel**

● We are a "foreign private issuer" and intend to follow certain home country corporate governance practices, and our shareholders may not have the same protections afforded to shareholders of companies that are subject to all corporate governance requirements under the listing rules of the Nasdaq Stock Market LLC, or the Nasdaq Listing Rules.

● 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 impact our results of operations.

**Risks Related to Our Financial Position and Capital Requirements**

***Except for the year December 31, 2021, we have incurred significant losses since our inception and anticipate that we will continue to incur losses for the foreseeable future.***

We are a regenerative and aesthetic medicine company focused on 3D bioprinting of tissues and organs, and medical aesthetics. Except for the year and December 31, 2021, we have incurred losses in each year since our inception in 2004. We incurred a total comprehensive loss of $16.9 million for the year ended December 31, 2022 and a total comprehensive income of $237,000 for the year ended December 31, 2021. As of December 31, 2022, we had an accumulated deficit of $89.7 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 with revenues from sales of our products and license of our technology, as well as from net proceeds from private and public offerings. Prior to February 2017, we financed our operations primarily from public offerings of our securities on the TASE, participation of business partners in product development collaborations, and government grants from the Israeli Innovation Authority, or the IIA. The amount of our future net losses will depend, in part, on the success of our collaborations and on the rate of our future expenditures. If and when we or our partners will obtain regulatory approval to market products, our future revenues will depend upon the size of any markets in which the products have received approval, and the ability to achieve sufficient market acceptance, reimbursement from third-party payors and adequate market share for the products in those markets.

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

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

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

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

● further develop and expand the manufacturing process for our products and product candidates;

● establish a sales, marketing, and distribution infrastructure to commercialize our products and product candidates for which we may obtain marketing approval;

● seek to identify and validate additional products and product candidates;

● maintain, protect, and expand our intellectual property portfolio;

● attract and retain skilled personnel;

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

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

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

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

We are conducting clinical and preclinical development of our products and product candidates, and we intend to continue advancing their development. Developing medical products is expensive, and we expect our research and development expenses to continue to be a material part of our expenses and may increase substantially in connection with our ongoing activities, particularly as we or our collaboration partners advance our products or product candidates in clinical trials.

As of December 31, 2022, our cash and cash equivalents together with short-term cash deposits accumulated to $29.7 million. Except for the year December 31, 2021, in which we incurred a total comprehensive income of $237,000, we had recurring losses from operations and negative operating cash flows since our inception. In February 2021, we closed a registered direct offering resulting in gross proceeds of $35 million and received an upfront payment of $14 million from AbbVie, as part of our Development, Exclusivity and Option Products Agreement with AbbVie. We will need to raise additional capital in the future to support our operations and product development activities. In the near term, we expect to continue to fund our operations and other development activities from the cash held by us, from milestones payments from business collaborators and through future equity financings.

Our operating plan may change as a result of many factors currently unknown to us, and we may need to seek additional funds sooner than planned, through public or private equity or debt financings, third-party funding, marketing and distribution arrangements, and other collaborations, strategic alliances, and licensing arrangements, or a combination of these approaches. 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. Conversely, we may need to seek additional funds at times when the market conditions for doing so are less favorable, noting, for example, the effect of inflation on the economy in the United States and global markets. For more information, see "—Risks Related to Our Business Operations—Our business, operating results and growth rates may be adversely affected by current or future unfavorable economic and market conditions and adverse developments with respect to financial institutions and associated liquidity risk." Any debt financing obtained by us could involve restrictive covenants relating to financial and operational matters, which may make it more difficult for us to obtain additional capital and to pursue business opportunities and could require us to use a portion of our cash flows to make debt service payments, which could place us at a competitive disadvantage relative to our less leveraged peers. If we raise additional funds through further issuances of equity, convertible debt securities, or other securities convertible into equity, our existing stockholders could suffer significant dilution in their percentage ownership of our company, and any new equity securities we issue could have rights, preferences, and privileges senior to those of holders of our common stock, including registration rights. If we are unable to obtain adequate financing or financing on terms satisfactory to us when we require it, our ability to support our business and to respond to business challenges could be significantly limited, and our business, operating results, financial condition, and prospects could be harmed.

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

If additional capital is not available to us when needed or on acceptable terms, we may be required to significantly curtail, delay, or discontinue one or more of our research or development programs or the commercialization of any products or product candidates, and we may be unable to expand our operations or otherwise capitalize on our business opportunities, as desired.

***The IIA grants we have received in the past for research and development expenditures may restrict our ability to manufacture products and transfer IIA funded know-how outside of Israel and require us to satisfy specified conditions.***

Our research and development efforts have been financed, in part, through the grants that we have received in the past from the IIA. The total gross amount of grants actually received by us from the IIA as of December 31, 2022 totaled approximately $10.1 million. We, therefore, must comply with the requirements of, and are subject to certain restrictions under, the Israeli Law for the Encouragement of Industrial Research and Development of 1984, or the Innovation Law and the IIA's rules and guidelines with respect to the use of intellectual property and other know-how resulting, directly or indirectly, in whole or in part, in accordance with or as a result of, research and development activities made according to a research and development program funded by the IIA, or the Approved Program, as well as any rights associated with such know-how (including later developments, which derive from, are based on, or constitute improvements or modifications of such know-how), or the IIA Funded Know-How. These restrictions involve obligations relating to royalty payments, reporting and local manufacturing, and limitations on the transfer of IIA Funded Know-How and the licensing of IIA Funded Know-How.

Such restrictions may impair our ability to perform or outsource manufacturing rights outside of Israel, or otherwise transfer our or license for R&D purpose our IIA Funded Know-How outside of Israel. These restrictions may also require us to obtain the approval of the IIA for certain actions and transactions and pay additional royalties and other amounts to the IIA. We cannot be certain that any approval of the IIA will be obtained on terms that are acceptable to us, or at all. Furthermore, the consideration available to our shareholders in a transaction involving the transfer outside of Israel of IIA Funded Know-How (such as a merger or similar transaction) or a transaction involving the licensing of IIA Funded Know-How for R&D purposes outside of Israel, may be reduced by any amounts that we are required to pay to the IIA.

If we fail to comply with the requirements of the Innovation Law, we may be subject to financial sanctions, to mandatory repayment of grants received by us (together with interest and penalties), as well as expose us to criminal proceedings. For additional information regarding the Innovation Law and the IIA, see "Item 4.B. Business Overview—Other Approvals—The Innovation Law and the IIA"

***We may not be able to correctly estimate or control our future operating expenses, which could lead to cash shortfalls.***

Our operating expenses may fluctuate significantly in the future for various reasons, many of which are outside of our control. These reasons may include:

● the time, resources, and expenses required to conduct clinical trials of, seek regulatory approvals for, manufacture, market, and sell our current products and any additional products we may develop;

● the time, resources, and expenses required to research and develop additional indications of our current products;

● the costs of preparing, filing, prosecuting, defending, and enforcing patent claims and other patent-related costs, including litigation costs or the results of such litigation;

● any product liability or other lawsuits related to our products and the costs associated with defending them or the results of such lawsuits;

● the costs to attract and retain personnel with the skills required for effective operations; and

● the costs associated with being a public company in the United States.

***It is difficult to forecast our future performance, which may cause our financial results to fluctuate unpredictably.***

Because we do not yet have an established commercial operating history, and because the market for our products and product candidates may rapidly evolve, it is hard for us to predict our future performance. A number of factors, many of which are outside of our control, may contribute to fluctuations in our financial results assuming that we receive marketing authorizations and begin selling our products. These factors may include variations in:

● market demand for, and acceptance of, our products;

● our ability to obtain or maintain regulatory approvals;

● our sales and marketing operations, or the effectiveness of these operations;

● performance of our third-party contractors;

● the availability of procedures or products that compete with our products;

● media coverage of our technologies, the procedures or products of our competitors or our industry; and

● natural disasters and political and economic instability, including wars, terrorism, political unrest, results of certain elections and votes, emergence of a pandemic, or other widespread health emergencies (or concerns over the possibility of such an emergency, including for example, the COVID-19 outbreak), boycotts, adoption or expansion of government trade restrictions, and other business restrictions).

**Risks Related to Commercialization of Our Products**

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

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

● the cost, safety, efficacy, and convenience of our products in relation to alternative treatments and products;

● the ability of third parties to enter into relationships with us without violating their existing agreements;

● the effectiveness of our sales and marketing efforts;

● 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 products are administered;

● 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 for, and timing of market introduction of, competing products;

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

● sufficient third-party insurance coverage or reimbursement.

Even if a potential product displays a favorable safety and efficacy profile in clinical trials, market acceptance of the product will not be known until after it is launched. Our efforts to educate the medical community and third-party payors on the benefits of the products 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.

***We have only limited clinical data to support sales of our products, which may make physicians, patients, third-party payors, and others in the medical community reluctant to accept or purchase our products.***

Physicians, patients, third party payors, and others in the medical community will only accept or purchase our products if they believe them to be safe and effective, with advantages over competing products or procedures. To date, we have collected only limited clinical data with which to assess the clinical and economic value of VergenixFG and VergenixSTR which we sell in Europe. The collection of clinical and economic data and the process of generating peer review publications in support of our product and procedure is an ongoing focus for us. If future publications of clinical studies indicate that procedures using the VergenixFG and VergenixSTR are less safe or less effective than competing products or procedures, patients may choose not to undergo our procedure, and physicians or others in the medical community may choose not to use our products. Furthermore, unsatisfactory patient outcomes or patient injury could cause negative publicity for our products, particularly in the early phases of product introduction.

***We have low scale experience in producing our rhCollagen, and if we are unable to manufacture our rhCollagen in high commercial quantities successfully and consistently to meet demand, our growth will be limited.***

We have experience manufacturing limited quantities of rhCollagen, the recombinant human type I collagen used for development with collaborators and in our products and product candidates. Our manufacturing capabilities will need to be further improved to meet the standard requirements for future clinical studies and for commercialization of our products and product candidates. To manufacture our rhCollagen in quantities that we believe will be sufficient to produce our end products and meet anticipated market demand, we will need to increase manufacturing capacity, which will involve significant challenges. In addition, the development of commercial-scale, regulation-compliant manufacturing capabilities will require us to invest substantial additional funds and hire and retain the technical personnel who have the necessary manufacturing experience. We may not successfully complete any required increase to existing manufacturing processes in a timely manner, or at all.

If there is a disruption to our internal manufacturing operations, we will have no other means of production for the components and products from such operations until we restore the affected facilities or develop alternative manufacturing facilities, which would delay our clinical trials or cause us to be unable to meet commercial demand for our products. In such case, we may need to arrange for third-party manufacturing of our components and products, which would be expensive and time consuming, assuming we can identify an appropriate third party manufacturer. Additionally, any damage to or destruction of our facilities or equipment may significantly impair our ability to manufacture our components and products on a timely basis.

If we are unable to produce our products in sufficient quantities to meet anticipated customer demand, our revenues, business, and financial prospects would be harmed. The lack of experience we have in producing commercial quantities of our components and products may also result in quality issues and product recalls. Any product recall could be expensive and generate negative publicity, which could impair our ability to market our products and further affect our results of operations. Manufacturing delays related to quality control could negatively impact our ability to bring our technologies to market, harm our reputation, and decrease our revenues.

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

We have limited experience in selling and marketing our products or any other products. To successfully commercialize our products we will need to develop these capabilities, either on our own or with others. We are seeking to enter into commercial alliances with third-party collaborators and distributors to utilize their development, marketing and distribution capabilities, but we may be unable to do so on favorable terms, if at all. If any future collaboration or distribution partners do not commit sufficient resources to commercialize our future products, and if 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 an internal team 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 products.

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

We operate in the regenerative and aesthetic medicine fields, which is rapidly changing. We have competitors both in the United States and internationally, including major multinational pharmaceutical companies, biotechnology companies, medical technology companies, and universities and other research institutions.

Many of our potential competitors have substantially greater financial, technical and other resources, such as larger research and development staff and experienced marketing and manufacturing organizations. Competition may increase further as a result of advances in the commercial applicability of technologies and greater availability of capital for investment in these industries. Our potential competitors may succeed in developing, acquiring, or licensing on an exclusive basis, products that are more effective or less costly than any products 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 products uneconomical or obsolete, and we may not be successful in marketing our products against competitors.

We are not aware of any competitors that produce collagen from plants or that produce recombinant type I human collagen.

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

If any of our products are approved for commercialization, it is our current intention to market them on a regional or worldwide basis in the jurisdictions where they may be approved, either alone or in collaboration with third parties. In addition, we may 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 product approval 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, or natural disasters including earthquakes, typhoons, floods, fires, emergence of a pandemic, or other widespread health emergencies (or concerns over the possibility of such an emergency, including for example, the COVID-19 pandemic).

***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 products that are approved could limit our ability to market those products and compromise our ability to generate revenue.***

The availability of reimbursement by governmental and private payors is essential for most patients to be able to afford expensive treatments. Sales of our products will depend substantially, both in Europe and in the United States, on the extent to which the costs of our products will be paid by health maintenance, managed care, pharmacy benefit, and similar healthcare management organizations, or reimbursed by government health administration authorities, private health coverage insurers, and other third-party payors. If reimbursement is not available, or is available only to limited levels, we may not be able to successfully commercialize our products. Even if we obtain coverage for our products, third-party payors may not establish adequate reimbursement amounts, which may reduce the demand for, or the price of, our products. If reimbursement is not available or is available only to limited levels, we may not be able to commercialize certain of our products.

Furthermore, publication of discounts by third-party payors or authorities may lead to further pressure on the prices or reimbursement levels within the country of publication and other countries. If reimbursement of our products is unavailable or limited in scope or amount, or if pricing is set at unacceptable levels, we or our partner may elect not to commercialize our products in such countries, and our business and financial condition could be adversely affected.

***Promotion of off-label uses of our products by physicians could adversely affect our business.***

Any regulatory approval of our products is limited to those specific indications for which our products have been deemed safe and effective by the regulatory authorities. In addition, any new indication for an approved product also requires regulatory approval. If we produce an approved product, we will rely on physicians to use and administer it as we have directed and for the indications described on the labeling. It is not, however, uncommon for physicians to use in 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 use our products for off-label uses, our ability to promote the products is limited to those indications that are specifically approved by the 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 regulation authorities' rules and guidelines relating to promotion and advertising can result in the regulation authorities' 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.

**Risks Related to the Clinical Development and Regulatory Approval of Our Products**

***We currently depend heavily on the future success of our BioInk and our medical aesthetics and 3D bioprinting product candidates. Any failure to successfully develop, obtain regulatory approval for, and commercialize these products or their end products, independently or in cooperation with a third-party collaborator, or the experience of significant delays in doing so, would compromise our ability to generate revenue and become profitable.***

We have invested a significant portion of our efforts and financial resources in the development of rhCollagen, BioInk, medical aesthetics and 3D bioprinting product candidates, and our Vergenix line of products. We currently depend heavily on the future success of our BioInk, medical aesthetics and 3D bioprinting product candidates. Our ability to generate revenues from our products and product candidates depends heavily on the successful development, approval, and commercialization of our products, which, in turn, depend on several factors, including the following:

● our ability to continue and support our rhCollagen platform technology and programs;

● our ability to establish and maintain strategic partnerships, including the Development, Exclusivity and Option Products Agreement with AbbVie;

● successfully initiating and completing future clinical trials and other studies required for our products and product candidates;

● demonstrating and maintaining the safety and efficacy of our products at a sufficient level of statistical or clinical significance and otherwise obtaining marketing approvals from regulatory authorities;

● establishing successful sales and marketing arrangements for our products in the jurisdictions where they may be approved;

● the availability of coverage and reimbursement by healthcare payors for our products in the jurisdictions where they may be approved;

● establishing a large scale facility as a second source for the manufacture of commercial and clinical quantities of our products, if approved; and

● other risks described in this "Risk Factors" section.

***Our products are based on novel technology, which makes it difficult to predict the time and cost of product development and potential regulatory approval.***

We have concentrated our product research and development efforts on our novel rhCollagen technology. The FDA has approved very few plant-expressed products. We may experience development challenges in the future related to our technology, which could cause significant delays or unanticipated costs, and we may not be able to solve such development challenges. We may also experience delays in developing a sustainable, reproducible, and scalable manufacturing process or transferring that process to commercial partners, if we decide to do so.

In addition, the clinical trial requirements of European regulatory authorities, the FDA, and other regulatory authorities and the criteria these regulators use to determine the safety and efficacy of a product vary substantially according to the type, complexity, novelty, and intended use and market of the potential products. The regulatory approval process for novel products such as ours can be more expensive and take longer than for other, better known or extensively studied products. Our products may also be designated by the FDA or other regulatory authorities as combination products, which include: (1) a product comprised of two or more regulated components, e.g., drug/device, biologic/device, drug/biologic, or drug/device/biologic, that are physically, chemically, or otherwise combined or mixed and produced as a single entity; (2) two or more separate products packaged together in a single package or as a unit and comprised of drug and device products, device and biological products, or biological and drug products; (3) a drug, device, or biological product packaged separately that according to its investigational plan or proposed labeling is intended for use only with an approved individually specified drug, device, or biological product where both are required to achieve the intended use, indication, or effect and where upon approval of the proposed product the labeling of the approved product would need to be changed, e.g., to reflect a change in intended use, dosage form, strength, route of administration, or significant change in dose; or (4) any investigational drug, device, or biological product packaged separately that according to its proposed labeling is for use only with another individually specified investigational drug, device, or biological product where both are required to achieve the intended use, indication, or effect. Combination Products containing a biologic/device then may be regulated as a biologic product, resulting in a longer regulatory approval process than the regulatory approval process for a medical device alone. Approvals by any regulatory authorities may not be indicative of what the FDA or other regulatory agencies may require for approval, and vice versa.

Regulatory requirements governing medical devices and other products for medical use have changed frequently and may continue to change in the future. Also, before a clinical trial can begin, an institutional review board, or IRB, at each institution at which a clinical trial will be performed must review the proposed clinical trial to assess the safety of the trial. In addition, adverse developments in clinical trials of comparable products conducted by others may cause European regulatory authorities, the FDA, or other regulatory authorities to change the requirements for approval of any of our products.

These regulatory agencies and additional or new requirements 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 our products, or lead to significant approval and post-approval limitations or restrictions. As we advance our products, we will be required to consult with these regulatory authorities, and comply with applicable requirements. If we fail to do so, we may be required to delay or discontinue development of our products. Delay or failure to obtain, or unexpected costs in obtaining, the regulatory approval necessary to bring a potential product to market could impair our ability to generate product revenue and to become profitable.

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

Identifying and qualifying patients to participate in clinical trials of our products and product candidates is critical to our success. The timing of clinical trials depends on our ability to recruit patients to participate in our clinical trials. We or our strategic partners may experience delays in patient enrollment in the future. If patients are unwilling to participate in our clinical trials because of negative publicity from adverse events in the biotechnology, pharmaceutical or medical technology 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 or our strategic partners 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:

● design of the trial protocol;

● size of the patient population;

● eligibility criteria for the trial in question;

● severity of the disease/wounds under investigation;

● perceived risks and anticipated benefits of the product under study;

● proximity and availability of clinical trial sites for prospective patients;

● availability of competing therapies, products, 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.

We are currently not conducting any clinical trials. We may not be able to initiate or continue future clinical trials if we cannot enroll a sufficient number of eligible patients to participate in the clinical trials required by European regulatory authorities, the FDA, or other regulatory authorities.

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 related to our products under evaluation. The discontinuation of patients in any one of our trials may cause us to delay or abandon such 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.

***Future clinical trials may not be successful or may be delayed.***

Before obtaining marketing approval from regulatory authorities for the sale of our products or product candidates or any future product, we or our strategic partners must conduct clinical trials to demonstrate the safety in humans for European CE marking certification, and the safety and efficacy of our products or product candidates in humans for other regulatory authorities such as the United States. From time to time, we work with contract research organizations, or CROs, which assist us in overseeing and implementing our clinical trials. Clinical trials are 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. We may not receive FDA regulatory approval for the conduct of any particular clinical trial in the United States or regulatory approval for conduct of such clinical trial in other countries. A failure of one or more clinical trials can occur at any stage of testing. Events that may prevent successful or timely completion of clinical development include:

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

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

● delays in obtaining required IRB approval at each clinical trial site;

● delays in recruiting suitable patients to participate in our clinical trials;

● imposition of a clinical hold by regulatory agencies, including after an inspection of our clinical trial operations or trial sites;

● failure by our CROs, other third parties or us to perform in accordance with clinical trial requirements or 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 products 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 products that are viewed to outweigh their potential benefits; or

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

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 design changes to our products or product candidates, we may need to conduct additional studies to bridge our modified products to earlier versions. Clinical trial delays could also shorten any periods during which we may have the exclusive right to commercialize our products or product candidates or allow our competitors to bring products to market before we do, which could impair our ability to successfully commercialize our products.

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

● fail to obtain, or be delayed in obtaining, marketing approval for our products or 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;

● 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;

● 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 products or product candidates and impair our ability to commercialize our products.

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

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

***Even if we or our strategic partners complete the necessary preclinical studies and clinical trials, we cannot predict when or if we will obtain regulatory approval to commercialize a product, 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. Even if our products or product candidates demonstrate safety and efficacy in clinical trials, the regulatory agencies may not complete their review processes in a timely manner, or we may not be able to obtain regulatory approval. Additional delays may result if an FDA Advisory Committee or other regulatory authority recommends non-approval or restrictions on approval. In addition, we may experience delays or rejections based upon additional government regulation from future legislation or administrative action, or changes in regulatory agency policy during the period of product development, clinical trials, and the review process. Regulatory agencies also may approve a treatment 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.

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

Treatment with our products or product candidates may cause side effects or other adverse events. In addition, since our products may in the future be 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, but may still impact the success of our clinical trials. Additionally, our products or product candidates could potentially cause other adverse events that have not yet been predicted. The experience of side effects and adverse events in our clinical trials could make it more difficult to achieve regulatory approval of our products or, if approved, could negatively impact the market acceptance of such products.

***Even if we or a strategic partner obtains regulatory approval for a product, our products will remain subject to regulatory scrutiny.***

Even if we or a strategic partnerobtain regulatory approval in a jurisdiction, the regulatory authority may still impose significant restrictions on the indicated uses or marketing of our products, or impose ongoing requirements for potentially costly post-approval studies or post-market surveillance. Advertising and promotional materials must comply with FDA, Federal Trade Commission, or FTC, and European and other countries' regulatory requirements and are subject to review by the FDA, FTC or other governmental authorities, in addition to other potentially applicable federal and state laws.

The laws that may affect our operations in the United States include:

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

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

● the federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, which created new federal criminal statutes that prohibit executing a scheme to defraud any healthcare benefit program and making false statements relating to healthcare matters;

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

● the federal physician sunshine requirements under the Patient Protection and Affordable Care Act, which requires manufacturers of drugs, devices, biologics, and medical supplies to report annually to the Centers for Medicare and Medicaid Services, or CMS, information related to payments and other transfers of value to physicians, other healthcare providers, and teaching hospitals, and ownership and investment interests held by physicians and other healthcare providers and their immediate family members; and

● foreign and state law equivalents of each of the above federal laws, such as the U.S. Foreign Corrupt Practices Act, or the FCPA, and anti-kickback and false claims laws that may apply to items or services reimbursed by any third-party payor, including commercial insurers; state laws that require pharmaceutical companies to comply with the pharmaceutical industry's voluntary compliance guidelines and the applicable compliance guidance promulgated by the federal government, or otherwise restrict payments that may be made to healthcare providers and other potential referral sources; state laws that require manufacturers to report information related to payments and other transfers of value to physicians and other healthcare providers or marketing expenditures; and state laws governing the privacy and security of health information in certain circumstances, many of which differ from each other in significant ways, thus complicating compliance efforts.

The scope of these laws and our lack of experience in establishing the compliance programs necessary to comply with this complex and evolving regulatory environment increase the risks that we may violate the applicable laws and regulations.

In addition, product manufacturers and their facilities are subject to continual review and periodic inspections by the European regulatory authorities, the FDA, and other regulatory authorities for compliance with cGMP or any applicable European or other governmental regulations. 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 products, one or more regulatory authorities could:

● 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;

● suspend any ongoing clinical trials;

● 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 and potentially lead to private litigation. The occurrence of any event or penalty described above may inhibit our ability to commercialize our products 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 preparing and filing the applications necessary to gain regulatory approvals for our products and product candidates to the extent that we decide to make such applications ourselves. Moreover, the products that are likely to result from our development programs are based on new technologies that have not been extensively used in humans. The regulatory requirements governing these types of products may be less well defined or more rigorous than for conventional products. As a result, we may experience a longer regulatory review process in connection with obtaining regulatory approvals, if any, of products that we develop. We intend to rely on independent consultants for regulatory services and compliance and product development and filings in Europe, the United States and elsewhere. Any failure by our consultants to properly advise us regarding, or properly perform tasks related to, regulatory submission and other requirements could compromise our ability to develop and obtain regulatory approval of our products.

***We are subject to stringent regulation and any adverse regulatory action may materially adversely affect our financial condition and business operations.***

Our products, development activities, and manufacturing processes are subject to extensive and rigorous regulation by numerous government agencies, including European regulatory authorities, the FDA, and other regulatory authorities. To varying degrees, each of these agencies monitors and enforces our compliance with laws and regulations governing the development, testing, manufacturing, labeling, marketing, and distribution of our products. The process of obtaining marketing approval or clearance in Europe, the United States, and other countries for new products or enhancements or modifications to existing products could:

● take a significant amount of time;

● require the expenditure of substantial resources;

● involve rigorous and expensive preclinical and clinical testing, as well as increased post-market surveillance;

● involve modifications, repairs, or replacements of our products; and

● result in limitations on the indicated uses of our products.

We cannot be certain that we, or our third-party collaborators, will receive required approval or clearance from European regulatory authorities, the FDA, or other regulatory authorities for new products or modifications to existing products on a timely basis. The failure to receive approval or clearance for significant new products or modifications to existing products on a timely basis could have a material adverse effect on our financial condition and results of operations.

Both before and after a product is commercially released, we and our third-party collaborators have ongoing responsibilities under FDA regulations. For example, we are required to comply with the FDA's Quality System Regulation, or QSR, which are the good manufacturing requirements that the FDA applies to medical devices, and which mandate that manufacturers adhere to certain requirements pertaining to, among other things, development of our products, validation of manufacturing processes, controls for purchasing product components, and documentation practices. As another example, FDA regulations require us to provide information to the FDA whenever there is evidence that reasonably suggests that a product may have caused or contributed to a death or serious injury, or that a malfunction occurred which would be likely to cause or contribute to a death or serious injury upon recurrence. Compliance with applicable regulatory requirements is subject to continual review and is monitored rigorously through, among other things, periodic inspections by the FDA, which may result in observations on Form 483 that require corrective action, and in some cases warning letters, and potentially stopping the manufacturing until issues are remedied. If the FDA were to conclude that we are not in compliance with applicable laws or regulations, or that any of our products are ineffective or pose an unreasonable health risk, the Company may withdraw or recall the product or the FDA could ban such products, detain or seize such products, order a recall, repair, replacement, or refund of such products, or require us to notify health professionals and others that the devices present unreasonable risks of substantial harm to the public health.

The FDA has been increasing its scrutiny of the medical device, drugs, and biologics industries, and regulatory agencies are expected to continue to scrutinize the industry closely with inspections, with possible enforcement actions by the FDA or other agencies. Additionally, the FDA may restrict manufacturing and impose other operating restrictions, enjoin and restrain certain violations of applicable law pertaining to medical products, and assess civil or criminal penalties against our officers, employees, or us. The FDA may also recommend prosecution to the Department of Justice. Any adverse regulatory action, depending on its magnitude, may restrict us from effectively manufacturing, marketing, and selling our products. In addition, negative publicity and product liability claims resulting from any adverse regulatory action could have a material adverse effect on our financial condition and results of operations.

Finally, the FDA issued regulations regarding "Current Good Manufacturing Practice Requirements for Combination Products" on January 22, 2013. These regulations may apply to some of our products if they are designated by the FDA as combination products, which are products composed of two or more regulated components, such as a drug and a medical device. There have been and will be additional costs associated with compliance with the FDA Good Manufacturing Practice Requirements regulations for Combination Products.

Governmental regulations have become increasingly stringent and more common, and we may become subject to even more rigorous regulation by governmental authorities in various countries in the future. Penalties for a company's non-compliance with governmental regulation could be severe, including revocation or suspension of a company's business license and criminal sanctions.

***The impact of healthcare reform and other changes in the healthcare industry and in healthcare spending is currently unknown, and may adversely affect our business model.***

The commercial potential for our approved products, if any, could be affected by changes in healthcare spending and policy in Europe, in the United States, and in other countries. We operate in a highly regulated industry and new laws, regulations, or judicial decisions, or new interpretations of existing laws, regulations, or decisions, related to healthcare availability, the method of delivery, or payment for healthcare products and services could negatively impact our business, operations, and financial condition.

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

The success of our business depends primarily upon our ability to identify, develop, and commercialize products based on our platform technology. Our research programs may fail to identify other potential products for clinical development for a number of reasons. Our research methodology may be unsuccessful in identifying potential products or our potential products 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 products require substantial technical, financial, and human resources. We may focus our efforts and resources on potential programs or products that ultimately prove to be unsuccessful.

**Risks Related to Our Reliance on Third Parties**

***We may not be successful in establishing and maintaining strategic partnerships, which could adversely affect our ability to develop and commercialize our rhCollagen based BioInks dermal fillers and other products such as breast implants and future products for medical aesthetics.***

 ****

To successfully develop and commercialize our products and product candidates, we will need substantial financial resources as well as expertise and physical resources and systems. We may elect to develop some or all of these physical resources and systems and expertise ourselves, or we may seek to collaborate with another company that can provide some or all of such physical resources and systems as well as financial resources and expertise. For example, in February 2021, we entered into a Development, Exclusivity and Option Products Agreement with AbbVie pursuant to which we and AbbVie will collaborate in the development and commercialization of dermal and soft tissue filler products for the medical aesthetics market, using our rhCollagen technology and AbbVie's technology. Additionally , we were previously party to a collaboration with Lung Biotechnology PBC, or LB, a wholly-owned subsidiary of United Therapeutics Corporation, pursuant to which we and LB collaborated in the 3D bio-printing of lungs and kidneys for transplant in humans, that terminated in February 2021.

We face significant competition in seeking appropriate partners for our products and product candidates, and the negotiation process is time-consuming and complex. In order for us to successfully partner our products and product candidates, potential partners must view our products and product candidates as economically valuable in markets they determine to be attractive in light of the terms that we are seeking and other available products for licensing by other companies. Even if we are successful in our efforts to establish strategic partnerships, the terms that we agree upon may not be favorable to us, and we may not be able to maintain such strategic partnerships if, for example, development or approval of a product is delayed or sales of an approved product are disappointing. Any delay in entering into strategic partnership agreements related to our products could delay the development and commercialization of our products and reduce their competitiveness even if they reach the market. If we fail to establish and maintain strategic partnerships related to our products, we will bear all of the risk and costs related to the development and commercialization of our products, and we will need to seek additional financing, hire additional employees and otherwise develop expertise which we do not have and for which we have not budgeted.

The risks in a strategic partnership include the following:

● the strategic partner may not apply the expected financial resources, efforts, or required expertise in developing the physical resources and systems necessary to successfully develop and commercialize a product or product candidate;

● the strategic partner may not invest in the development of a sales and marketing force and the related infrastructure at levels that ensure that sales of the products reach their full potential;

● we may be required to undertake the expenditure of substantial operational, financial, and management resources;

● we may be required to issue equity securities that would dilute our existing shareholders' percentage ownership;

● we may be required to assume substantial actual or contingent liabilities;

● we, or our strategic partner, may not receive requisite regulatory approvals;

● strategic partners could decide to withdraw a development program, or move forward with a competing product developed either independently or in collaboration with others, including our competitors;

● disputes may arise between us and a strategic partner that delay the development or commercialization or adversely affect the sales or profitability of the product; or

● the strategic partner may independently develop, or develop with third parties, products that could compete with our products.

In addition, a strategic partner for one or more of our products or product candidates may have the right to terminate the collaboration at its discretion. For example, AbbVie may terminate our Development, Exclusivity and Option Products Agreement upon 60 days' written notice to us for any or no reason. Furthermore, in February 2021, LB exercised its right to terminate the license agreement we were party to. Any early termination in a manner adverse to us could have a material adverse effect on our liquidity, financial condition and results of operations. Any termination may require us to seek a new strategic partner, which we may not be able to do on a timely basis, if at all, or require us to delay or scale back our development and commercialization efforts. The occurrence of any of these events could adversely affect the development and commercialization of our products or product candidates and materially harm our business and stock price by delaying the development of our products, and the sale of any products that may be approved by the FDA or other regulatory agencies, by slowing the growth of such sales, by reducing the profitability of the product and/or by adversely affecting the reputation of the product.

Further, a strategic partner may breach an agreement with us, and we may not be able to adequately protect our rights under these agreements. Furthermore, a strategic partner will likely negotiate for certain rights to control decisions regarding the development and commercialization of our products, if approved, and may not conduct those activities in the same manner as we would do so.

***We expect to depend upon third-party collaborators, distributors and resellers for a significant portion of our sales.***

We expect to rely primarily upon sales through independent collaborators, distributors and resellers. While we are highly dependent upon acceptance of our products and solutions by such third parties and their active marketing and sales efforts relating to our products, most of our distributors and resellers will not be obligated to deal with us exclusively and are not contractually subject to minimum purchase requirements. In addition, some of our distributors and resellers may sell competing products or solutions. As a result, our distributors and resellers may give higher priority to products or services of our competitors, thereby reducing their efforts in selling our products and services.

There can be no assurance that such distributors and resellers will act as effective sales agents for us, that they will remain our partners, or that, if we terminate or lose any of them, we will be successful in replacing them. Any disruption in our distribution channels could adversely affect our business, operating results, and financial condition.

***We expect to rely on third parties to conduct some 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 parts of these items.

Any of these third parties may terminate their engagements with us at any time or upon advance notice. 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.

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 FDA, European, or other approvals of our products.

Reliance on third-party manufacturers entails risks to which we would not be subject if we manufactured the products 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 non-renewal 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 of action from European regulatory authorities, the FDA, or other regulatory authorities, including injunction, recall, seizure, or total or partial suspension of production.

***If we or our third parties on which we rely cannot manufacture our products at sufficient yields, we may experience delays in development, regulatory approval, and commercialization.***

Commercialization of our products require access to, or development of facilities to manufacture our products at sufficient yields and at a commercial scale. We have limited experience in large scale manufacturing volumes that are expected to be necessary to support large-scale sales. Our efforts to establish these capabilities may not meet our requirements as to scale-up, yield, cost, potency, or quality in compliance with cGMP. Future clinical trials should be conducted with product produced under applicable cGMP regulations. Failure to comply with these regulations would delay the regulatory approval process. Even an experienced third-party manufacturer may encounter difficulties in production, including:

● costs and challenges associated with scale-up and attaining sufficient manufacturing yields;

● supply chain issues, including the timely availability and shelf life requirements of raw materials and supplies;

● quality control and assurance;

● shortages of qualified personnel and capital required to manufacture large quantities of product;

● compliance with regulatory requirements that vary in each country where a product might be sold;

● capacity limitations and scheduling availability in contracted facilities; and

● natural disasters that affect facilities and possibly limit production.

Any delay or interruption in the supply of our products could have a material adverse effect on our business and operations.

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 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 or the European authorities 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.

Additionally, if supply from one approved manufacturer is interrupted, there could be a significant disruption in commercial supply. Switching manufacturers may involve substantial costs and is likely to result in a delay in our desired clinical and commercial timelines.

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

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

We expect to rely heavily on hospitals, clinic centers, and other institutions and third parties, including the principal investigators and their staff, to carry out our future clinical trials in accordance with our clinical protocols and designs. We also expect to rely on a number of CROs to assist in undertaking, managing, monitoring, and executing future clinical trials as well as clinical data management organizations, medical institutions, and clinical investigators to conduct our development efforts in the future. We compete with many other companies for the resources of these third parties, and large pharmaceutical and medical device companies often have significantly more extensive agreements and relationships with such third-party providers, and such third-party providers may prioritize the requirements of such large pharmaceutical and medical device companies over ours. The third parties on whom we rely may terminate their engagements with us at any time, which may cause delay in the development and commercialization of our products or product candidates. If any such third party terminates its engagement with us or fails to perform as agreed, we may be required to enter into alternative arrangements, which would result in significant cost and delay to our product development program. Moreover, our agreements with such third parties generally do not provide assurances regarding employee turnover and availability, which may cause interruptions in the research on our products by such third parties.

Moreover, while our reliance on these third parties for certain development and management activities will reduce our control over these activities, it will not relieve us of our responsibilities. For example, European regulatory authorities, the FDA, and other regulatory authorities require compliance with regulations and standards, including GCP requirements, for designing, conducting, monitoring, recording, analyzing, and reporting the results of clinical trials to ensure that the data and results from trials are credible and accurate and that the rights, integrity, and confidentiality of trial participants are protected. Although we rely on third parties to conduct our clinical trials, we are responsible for ensuring that each of these clinical trials is conducted in accordance with its general investigational plan and protocol under legal and regulatory requirements. Regulatory authorities enforce these GCP requirements through periodic inspections of trial sponsors, principal investigators, and trial sites. If we or any of our CROs fail to comply with applicable GCP requirements, the clinical data generated in our clinical trials may be deemed unreliable, and European regulatory authorities, the FDA, or other regulatory authorities may require us to perform additional clinical trials before approving our marketing applications. We cannot assure you that upon inspection by a regulatory authority, such regulatory authority will determine that any of our clinical trials comply with GCP requirements.

If CROs and other third parties do not successfully carry out their duties under their agreements with us, if the quality or accuracy of the data they obtain is compromised due to their failure to adhere to trial protocols or to regulatory requirements, or if they otherwise fail to comply with regulations and trial protocols or meet expected standards or deadlines, the trials of our products or product candidates may not meet regulatory requirements. If trials do not meet regulatory requirements or if these third parties need to be replaced, the development of our products or product candidates may be delayed, suspended, or terminated, or the results may not be acceptable. If any of these events occur, we may not be able to obtain regulatory approval of our products on a timely basis, at a reasonable cost, or at all.

***Our reliance on third parties may require 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 products, 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 strategic partners, 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 products.

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.

***It could be difficult to replace some of our suppliers and equipment vendors.***

Outside vendors provide key components, raw materials, and equipment used in the manufacture of our products. An uncorrected defect or supplier's variation in a component or raw material, either unknown to us or incompatible with our manufacturing process, could harm our ability to manufacture products. We may not be able to find a sufficient alternative supplier in a reasonable time period, or on commercially reasonable terms, if at all, and our ability to produce and supply our products could be impaired.

If we were suddenly unable to purchase from one or more of these companies, we would need a significant period of time to qualify a replacement, and the production of any affected products could be disrupted. While it is our policy to maintain sufficient inventory of components so that our production will not be significantly disrupted even if a particular component or material is not available for a period of time, we remain at risk that we will not be able to qualify new components or materials quickly enough to prevent a disruption if one or more of our suppliers ceases production of important components or materials, or if we are unable to quickly procure replacement equipment.

**Risks Related to Our Business Operations**

 ****

***Our future success depends on our ability to retain senior management, consultants, and advisors and to attract, retain, and motivate qualified personnel.***

We are dependent on principal members of our executive team listed under "Management" in this Annual Report on Form 20-F, the loss of whose services may adversely impact the achievement of our objectives. While we have entered into employment agreements with each member of our senior management, any of them could leave our employment at any time, subject to advance notice periods. 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 medical device companies for individuals with similar skill sets. In addition, failure to succeed in 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 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.

***Our business and operations would suffer in the event of computer system failures or security breaches***.

Despite the implementation of security measures, our internal computer systems, and those of our contract research organizations, or CROs and other third parties on which we rely, are vulnerable to damage from computer viruses, unauthorized access, cyber-attacks, natural disasters, fire, terrorism, war, and telecommunication and electrical failures. If such an event were to occur and interrupt our operations, it could result in a material disruption of our drug development programs. For example, the loss of clinical trial data from ongoing or planned clinical trials could result in delays in our regulatory approval efforts and significantly increase our costs to recover or reproduce the data. To the extent that any disruption or security breach results in a loss of or damage to our data or applications, loss of trade secrets or inappropriate disclosure of confidential or proprietary information, including protected health information or personal data of employees or former employees, access to our clinical data, or disruption of the manufacturing process, we could incur liability and the further development of our drug candidates could be delayed. We may also be vulnerable to cyber-attacks by hackers or other malfeasance. This type of breach of our cybersecurity may compromise our confidential information and/or our financial information and adversely affect our business or result in legal proceedings. Further, these cybersecurity breaches may inflict reputational harm upon us that may result in decreased market value and erode public trust.

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

As of March 15, 2023, we had 73 employees. As we mature and undertake the activities required to advance our products and product candidates and to operate as a public company in the United States, we expect to expand our full-time employee base and to hire more consultants and contractors. Our management may need to divert a disproportionate amount of its attention away from our day-to-day activities and devote a substantial amount of time to managing these growth activities. We may not be able to effectively manage the expansion of our operations, which may result in weaknesses in our infrastructure, operational setbacks, 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 products. 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 products 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 regulations, provide accurate information to European regulatory authorities, the FDA and other regulatory authorities, comply with healthcare fraud and abuse laws and regulations, 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.

***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 products harm patients, or is perceived to harm patients even when such harm is unrelated to our products, 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 products in clinical trials and the sale of any products exposes us to the risk of product liability claims. Product liability claims might be brought against us by consumers, healthcare providers, pharmaceutical and medical device companies, or others that sell or otherwise come into contact with our products. There is a risk that our products may induce adverse events. If we cannot successfully defend against product liability claims, we could incur substantial liability and costs. In addition, regardless of merit or eventual outcome, product liability claims may result in:

● impairment of our business reputation;

● withdrawal of clinical trial participants;

● costs due to related litigation;

● distraction of management's attention from our primary business;

● substantial monetary awards to patients or other claimants;

● the inability to commercialize our products;

● decreased demand for our products, if approved for commercial sale; and

● impairment of our ability to obtain product liability insurance coverage.

We currently carry product liability insurance of $5.0 million for sales in Europe of VergenixFG and VergenixSTR. We intend to acquire product liability insurance before commercializing any of our other products. However, we may not be able to obtain insurance coverage at a reasonable cost or in sufficient amounts to protect us against losses due to product liability. If we obtain marketing approval for additional products, we intend to obtain insurance coverage to include the sale of those 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 medical treatments that had unanticipated adverse effects. A product liability claim or series of claims brought against us could cause our ordinary share price to decline and, if judgments exceed our insurance coverage, could materially and adversely affect our financial position.

***Our development and production of rhCollagen relies upon the continued availability of tobacco plants, and any interruption in availability or supply of tobacco plants may delay production and adversely affect commercial utilization of our rhCollagen-based products.***

Our products are all based on our rhCollagen extracted from tobacco plants. Any disruption to the supply of tobacco plants or any change in its availability for use would delay our production of collagen and adversely affect commercial utilization of our products.

The occurrence of severe adverse weather conditions, soil salination or crop diseases may have a potentially devastating impact upon our tobacco production. The effect of severe adverse weather conditions or the occurrence and effect of crop disease may reduce yields in our plants or require higher levels of investment to maintain yields, even when only a portion of the crop is damaged. We cannot assure you that severe future adverse weather conditions will not adversely impact our operating results and financial condition. Although some crop diseases are treatable, the cost of treatment is high, and we cannot assure that such events in the future will not adversely affect our operating results and financial condition.

***If our existing rhCollagen production site or any new facility is damaged or destroyed, or production at this facility is otherwise interrupted, our business and prospects would be negatively affected.***

We currently have a single, small-scale production site in Israel where we manufacture rhCollagen. If our existing production facility or the new facility, or the equipment in it, is damaged or destroyed, we likely would not be able to quickly or inexpensively replace our production capacity. Any new facility needed to replace our existing production facility would need to comply with the necessary regulatory requirements and be tailored to our production requirements and processes. We would need regulatory approval before using any products manufactured at a new facility in clinical trials or selling any products that are ultimately approved. Such an event could delay our clinical trials or, if any of our products are approved by the regulator, reduce or eliminate our product sales.

***If we fail to comply with environmental, health, and safety laws and regulations, we could become subject to fines or penalties or incur costs that could have a material adverse impact 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. These laws, regulations, and permits could potentially require the expenditure by us of significant amounts for compliance or remediation. If we fail to comply with such laws, regulations, or permits, we may be subject to fines and other civil, administrative, or criminal sanctions, including the revocation of permits and licenses necessary to continue our business activities. See "Item 4.B. Environmental, Health, and Safety Matters" for additional information.

Our operations involve the use of hazardous 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.

***We may use our financial and human resources to pursue a particular research program or product and fail to capitalize on programs or products 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 products 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 products may not yield any commercially viable products. If we do not accurately evaluate the commercial potential or target market for a particular product, we may relinquish valuable rights to that product 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, or we may allocate internal resources to a product in a therapeutic area in which it would have been more advantageous to enter into a collaboration arrangement.

***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 adversely affect our earnings and results of operations.***

We currently operate in two different currencies. While the U.S. dollar is our functional and reporting currency, we incur a portion of our expenses in NIS. As a result, our financial results may be adversely affected by fluctuations in currency exchange rates.

We are exposed to the risks that the NIS may appreciate relative to the U.S. dollar, in such event, the dollar-denominated results of operations would be adversely affected. We cannot predict any future trends in the rate of inflation in Israel or the rate of devaluation (if any) of the NIS against the dollar. For example, the average exchange rate of the dollar against the NIS decreased in 2021 and 2020, but increased in 2022. Market volatility and currency fluctuations may limit our ability to cost-effectively hedge against our foreign currency exposure. 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.

***We or the third parties upon whom we depend may be adversely affected by natural disasters and/or health epidemics, and our business continuity and disaster recovery plans may not adequately protect us from a serious disaster.***

Natural disasters could severely disrupt our operations and have a material adverse effect on our business, results of operations, financial condition and prospects. If a natural disaster, power outage, health epidemic or other event occurred that prevented us from using all or a significant portion of our office, manufacturing and/or lab spaces, that damaged critical infrastructure, such as the manufacturing facilities of our third-party contract manufacturers, CROs, clinical sites, third parties ongoing activities and schedules or that otherwise disrupted operations, it may be difficult or, in certain cases, impossible for us to continue our plans and business for a substantial period of time.

Our business could be adversely impacted by the effects of the coronavirus outbreak originating in China, or by other epidemics. In addition, such an event may cause other parties to slow down their activities and schedules and therefore influence our timelines. A health epidemic or other outbreak, including the current coronavirus outbreak, may materially and adversely affect our business, financial condition and results of operations.

The disaster recovery and business continuity plans we have in place may prove inadequate in the event of a serious disaster or similar event. We may incur substantial expenses as a result of the limited nature of our disaster recovery and business continuity plans, which could have a material adverse effect on our business.

***Our business may be adversely affected if there is a resurgence of the COVID-19 pandemic.***

Public health epidemics or outbreaks could adversely impact our business. In late 2019, a novel strain of COVID-19, also known as coronavirus, was reported in Wuhan, China. Initially the outbreak was largely concentrated in China, but it rapidly spread to countries across the globe, including in Israel and the United States. Many countries around the world, including in Israel and the United States, implemented significant governmental measures to control the spread of the virus, including temporary closure of businesses, severe restrictions on travel and the movement of people, and other material limitations on the conduct of business. In response, for several months in 2020, we implemented remote working and workplace protocols for our employees in accordance Israeli Ministry of Health requirements to ensure employee safety and all employees have been instructed on and encouraged to practice best social distancing behaviors.

If there is a resurgence of COVID-19 its spread may materially affect us economically. While the potential economic impact brought by, and the duration of, sany future resurgence of the COVID-19 pandemic may be difficult to assess or predict, it has already caused, and could result in further, significant disruption of global financial markets, reducing our ability to access capital, which could in the future negatively affect our liquidity and financial position. In addition, the trading prices for other companies have been highly volatile as a result of the COVID-19 pandemic. As a result, we may face difficulties raising capital through sales of our ordinary shares or other securities and such sales may be on unfavorable terms. To the extent that future waves of COVID-19 disrupt normal business operations, we may face operational challenges with our services, and we likely will have to adopt remote working and workplace protocols for employees in accordance with government requirements and other measures to minimize such impact.

The extent to which COVID-19 impacts our operations will depend on future developments, which are highly uncertain and cannot be predicted with confidence, including the duration and severity of the outbreak, and the actions that may be required to contain COVID-19 or treat its impact. In particular, the extent to which any resurgence of the COVID-19 pandemic may impact our business and financial performance will depend on future developments, which are highly uncertain and cannot be predicted with confidence including our research and clinical trials and our ability to raise capital, could affect the operations of key governmental agencies and could result in the inability of our suppliers to deliver components or raw materials on a timely basis or at all, each of which in turn could have an adverse impact on our business, financial condition and results of operation.

***Our business, operating results and growth rates may be adversely affected by current or future unfavorable economic and market conditions and adverse developments with respect to financial institutions and associated liquidity risk.***

Our business depends on the economic health of the global economies. If the conditions in the global economies remain uncertain or continue to be volatile, or if they deteriorate, including as a result of the impact of military conflict, such as the war between Russia and Ukraine, terrorism or other geopolitical events, our business, operating results and financial condition may be materially adversely affected. Economic weakness, inflation and increases in interest rates, limited availability of credit, liquidity shortages and constrained capital spending have at times in the past resulted, and may in the future result, in challenging and delayed sales cycles, slower adoption of new technologies and increased price competition, and could negatively affect our ability to forecast future periods, which could result in an inability to satisfy demand for our products and a loss of market share.

In addition, increases in inflation raise our costs for commodities, labor, materials and services and other costs required to grow and operate our business, and failure to secure these on reasonable terms may adversely impact our financial condition. Additionally, increases in inflation, along with the uncertainties surrounding COVID-19, geopolitical developments and global supply chain disruptions, have caused, and may in the future cause, global economic uncertainty and uncertainty about the interest rate environment, which may make it more difficult, costly or dilutive for us to secure additional financing. A failure to adequately respond to these risks could have a material adverse impact on our financial condition, results of operations or cash flows.

More recently, the closures of SVB and Signature Bank and their placement into receivership with the FDIC created bank-specific and broader financial institution liquidity risk and concerns. Although we do not hold accounts in these banks and although the Department of the Treasury, the Federal Reserve and the FDIC jointly released a statement that depositors at SVB and Signature Bank would have access to their funds, even those in excess of the standard FDIC insurance limits, under a systemic risk exception, future adverse developments with respect to specific financial institutions or the broader financial services industry may lead to market-wide liquidity shortages, impair the ability of companies to access near-term working capital needs, and create additional market and economic uncertainty. There can be no assurance that future credit and financial market instability and a deterioration in confidence in economic conditions will not occur. Our general business strategy may be adversely affected by any such economic downturn, liquidity shortages, volatile business environment or continued unpredictable and unstable market conditions. If the current equity and credit markets deteriorate, or if adverse developments are experienced by financial institutions, it may cause short-term liquidity risk and also make any necessary debt or equity financing more difficult, more costly, more onerous with respect to financial and operating covenants and more dilutive. Failure to secure any necessary financing in a timely manner and on favorable terms could have a material adverse effect on our growth strategy, financial performance and stock price and could require us to alter our operating plans. In addition, there is a risk that one or more of our service providers, financial institutions, manufacturers, suppliers and other partners may be adversely affected by the foregoing risks, which could directly affect our ability to attain our operating goals on schedule and on budget.

 **

***Environmental, social and corporate governance (ESG) issues, including those related to climate change and sustainability, may have an adverse effect on our business, financial condition and results of operations and damage our reputation.***

 **

There is an increasing focus from certain investors, customers, consumers, employees and other stakeholders concerning ESG matters. Additionally, public interest and legislative pressure related to public companies' ESG practices continue to grow. If our ESG practices fail to meet regulatory requirements or investor, customer, consumer, employee or other shareholders' evolving expectations and standards for responsible corporate citizenship in areas including environmental stewardship, support for local communities, board of Directors and employee diversity, human capital management, employee health and safety practices, product quality, supply chain management, corporate governance and transparency, our reputation, brand and employee retention may be negatively impacted, and our customers and suppliers may be unwilling to continue to do business with us.

Customers, consumers, investors and other shareholders are increasingly focusing on environmental issues, including climate change, energy and water use, plastic waste and other sustainability concerns. Concern over climate change may result in new or increased legal and regulatory requirements to reduce or mitigate impacts to the environment. Changing customer and consumer preferences or increased regulatory requirements may result in increased demands or requirements regarding plastics and packaging materials, including single-use and non-recyclable plastic products and packaging, other components of our products and their environmental impact on sustainability, or increased customer and consumer concerns or perceptions (whether accurate or inaccurate) regarding the effects of substances present in certain of our products. Complying with these demands or requirements could cause us to incur additional manufacturing, operating or product development costs.

If we do not adapt to or comply with new regulations, including the SEC's published proposed rules that would require companies to provide significantly expanded climate-related disclosures in their periodic reporting, which may require us to incur significant additional costs to comply and impose increased oversight obligations on our management and board of directors, or fail to meet evolving investor, industry or stakeholder expectations and concerns regarding ESG issues, investors may reconsider their capital investment in our Company, we may become subject to penalties, and customers and consumers may choose to stop purchasing our products, if approved for commercialization, which could have a material adverse effect on our reputation, business or financial condition.

**Risks Related to Our Intellectual Property**

***We have an extensive worldwide patent portfolio. The cost of maintaining our patent protection is high and maintaining our patent protection requires continuous review and compliance in order to maintain worldwide patent protection. We may not be able to effectively maintain our intellectual property position throughout the major markets of the world.***

The U.S. Patent and Trademark Office, or U.S. PTO, and foreign patent authorities require maintenance fees and payments as well as continued compliance with a number of procedural and documentary requirements. Non-compliance may result in abandonment or lapse of the subject patent or patent application, resulting in partial or complete loss of patent rights in the relevant jurisdiction. Non-compliance may result in reduced royalty payments for lack of patent coverage in a particular jurisdiction from our collaboration partners or may result in competition, either of which could have a material adverse effect on our business.

We have made, and will continue to make, certain strategic decisions in balancing costs and the potential protection afforded by the patent laws of certain countries. As a result, we may not be able to prevent third parties from practicing our inventions in all countries throughout the world, or from selling or importing products made using our inventions in and into the United States or other countries. Third parties may use our technologies in territories in which we have not obtained patent protection to develop their own products and, further, may infringe our patents in territories which provide inadequate enforcement mechanisms, even if we have patent protection. Such third-party products may compete with our products, and our patents or other intellectual property rights may not be effective or sufficient to prevent them from competing.

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

We rely upon a combination of granted patents, pending patent applications, trade secret protection, and confidentiality agreements to protect the intellectual property related to our products and product candidates. The strength of patents in the field of regenerative medicine involves complex legal and scientific questions and can be uncertain. The patent applications that we own may fail to result in issued patents with claims that cover our products in the United States or in other 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 products, 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 products, or prevent others from designing around our claims. Any of these outcomes could impair our ability to prevent competition from third parties.

Our ability to attract third parties to collaborate with us to develop products and our ability to commercialize future products may be adversely affected if the patent applications we hold with respect to our techniques or products 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 products. Third parties may challenge their validity or enforceability of our patents or patents that issue in the future from our patent applications, which may result in such patents being narrowed, invalidated, or held unenforceable. Even if our patents and patent applications are not challenged by third parties, they may not prevent others from designing around our claims and may not otherwise adequately protect our products. If the breadth or strength of protection provided by the patents and patent applications we hold with respect to our products is threatened, our ability to commercialize our products may be adversely effected.

Discoveries are generally published in the scientific literature well after their actual development, and patent applications in the United States and other countries are typically not published until 18 months after filing and in some cases are never published. Therefore, we cannot be certain that we were the first to make the inventions claimed in our owned granted patents or patent applications, or that we were the first to file for patent protection covering such inventions. Subject to meeting other requirements for patentability, for United States patent applications filed prior to March 16, 2013, the first to invent the claimed invention is entitled to receive patent protection for that invention while, outside the United States, the first to file a patent application encompassing the invention is entitled to patent protection for the invention. In addition, patents have a limited lifespan. In the United States, the expiration of a patent is generally 20 years from the earliest non-provisional filing date. Various extensions may be available, but the life of a patent, and the protection it affords, is limited. Once the patent life has expired for a product, we may be open to competition from third party products, including products that are copies of our products. 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 our proprietary know-how and other proprietary information that is not patentable or that we elect not to patent. For example, many of our discovery, development, and manufacturing processes involve proprietary know-how, information, or technology that is not covered by patents. We seek to protect our trade secrets and 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 contractually require 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, 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 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 in other countries. 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 patents 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. 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 technologies. As the biotechnology and pharmaceutical industries expand and more patents are issued, the risk increases that our products 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 products. 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 products 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 products or any final product itself, the holders of any such patents may be able to block our ability to commercialize such product 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 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.

The patent landscape in competitive product areas is highly complex and there may be patents of third parties of which we are unaware that may result in claims of infringement. Accordingly, there can be no assurance that our products do not infringe proprietary rights of third parties. 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 products. Defense of such claims, regardless of their merit, would involve substantial litigation expense and would be a substantial diversion of financial and 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 intend, if necessary, to vigorously enforce our intellectual property in order to protect the proprietary position of our products. Active efforts to enforce our patents may include litigation, post-grant patent challenges, administrative proceedings, or all of the foregoing, depending on the potential benefits that might be available from those actions and the costs associated with undertaking those efforts against third parties. We review and monitor publicly available information regarding products that may be competitive with our products and intend to assert our intellectual property rights where appropriate.

***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 products and product candidates. We may fail to obtain any of these licenses at a reasonable cost or on reasonable terms, if at all. In that event, we 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 products.

***We may be involved in lawsuits or administrative proceedings to obtain, protect or enforce our patents, which could be expensive, time consuming, and unsuccessful.***

Competitors may infringe our patents. To counter infringement or unauthorized use, we may be required to file an infringement suit, which can be expensive and time consuming. In addition, in an infringement proceeding, the defendant may file a countersuit, challenging the validity or enforceability of our patent. In that case, a court may decide that a patent of ours is not valid, is unenforceable, or is not infringed, or it 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.

We may not be able to prevent misappropriation of our intellectual property rights, particularly in countries where the laws may not protect those rights.

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

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

On September 16, 2011, the Leahy-Smith America Invents Act, or the Leahy-Smith Act, was signed into law. The Leahy-Smith Act includes a number of significant changes to U.S. patent law, including provisions that affect the way patent applications are prosecuted and also affect patent litigation. The U.S. PTO has developed regulations and procedures to govern administration of the Leahy-Smith Act, and many of the substantive changes to patent law associated with the Leahy-Smith Act, and in particular, the first to file provisions which were enacted March 16, 2013. However, it is not clear what, if any, impact the Leahy-Smith Act will have on the operation of our business. The Leahy-Smith Act and its implementation could increase the uncertainties and costs surrounding the prosecution of our patent applications and the enforcement or defense of our issued patents. We may become involved in post-grant proceedings challenging our patents or the patents of others, and the outcome of any such proceedings are highly uncertain. An unfavorable outcome in any such proceedings could reduce the scope of, or invalidate, our patent rights, allow third parties to commercialize our technology and compete directly with us, or result in our inability to manufacture, develop, or commercialize our products without infringing the patent rights of others.

***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 employees and personnel were previously employed at universities, medical institutions, or other biotechnology or pharmaceutical companies. 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. Section 134 of the Israeli Patents Law, 5727-1967, or the Patents Law, grants employees the right to receive consideration for service inventions unless otherwise provided in an agreement between the parties. According to a decision by the special Committee for Compensations and Royalties formed under the Patents Law, or the Committee, an employee's right to receive consideration for service inventions is a personal right and is entirely separate from the proprietary rights in such invention. A decision in May 2014 by the Committee clarifies that the right to receive consideration under Section 134 can be waived and that such waiver does not necessarily have to be explicit. However, the Committee has the authority to examine, on a case by case basis, the general contractual framework between the parties, using interpretation rules of the general Israeli contract laws. Although such decision seems to alleviate the requirement to obtain an explicit waiver for royalties for service inventions under Section 134 of the Patents Law, to the extent that there is no explicit waiver in an employment agreement, the existence of such waiver will be subject to the interpretation of the Committee. Further, the Committee has not yet determined one specific formula for calculating this remuneration (but rather uses the criteria specified in the Patents Law) 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. Ownership disputes may arise in the future, for example, from conflicting obligations of consultants or others who are involved in developing our products. 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 requires compliance with various procedural, document submissions, fee payments, 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 are and 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 products or product candidates could be found invalid or unenforceable if challenged in court or in administrative proceedings.***

If we initiate legal proceedings against a third party to enforce a patent covering one of our products or product candidates, the defendant may contend that the patent covering our product is invalid, unenforceable, or fails to cover the product or the infringing product. In patent litigation in the United States, defendants commonly allege that asserted patent claims are invalid and unenforceable. Grounds for a validity challenge could be an alleged failure to meet one or more of several statutory requirements, including lack of novelty, obviousness, lack of written description, indefiniteness, and non-enablement. Grounds for an unenforceability assertion could be an allegation that someone connected with prosecution of the patent withheld relevant information from the U.S. PTO, or made a misleading statement, during prosecution. Third parties may also raise similar claims before administrative bodies in the United States or abroad, even outside the context of litigation. Such mechanisms include re-examination, post grant review, and equivalent proceedings in foreign jurisdictions, such as opposition proceedings. Such proceedings could result in revocation, amendments to our patent claims, or statements being made on the record such that our claims may no longer be construed to cover our products. The outcome following legal assertions of invalidity and unenforceability is unpredictable. With respect to the validity question, for example, we cannot be certain that there is no invalidating prior art, of which we and the patent examiner were unaware during prosecution. If a defendant were to prevail on a legal assertion of invalidity, unenforceability, or non-infringement, we would lose at least part, and perhaps all, of the patent protection on our products. For example, as further described below, in July 2017, Fibrogen, Inc., or Fibrogen, prevailed in an administrative challenge to one of our patents in Europe, resulting in the revocation of the patent and the abandonment of another patent. Even if resolved in our favor, litigation, or other legal proceedings relating to intellectual property claims may cause us to incur significant expenses, and could distract our technical and management personnel from their normal responsibilities. Moreover, third parties may continue to initiate new proceedings in the United States and foreign jurisdictions to challenge our patents from time to time.

In addition, there could be public announcements of the results of hearings, motions, or other interim proceedings or developments, and if securities analysts or investors perceive these results to be negative, it could have a substantial adverse effect on the market price of our ordinary shares. Such litigation or proceedings could substantially increase our operating losses and reduce the resources available for development activities or any future sales, marketing, or distribution activities.

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

As is the case with other companies in our industry, 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 therefore is costly, time consuming, and inherently uncertain. In addition, in recent years, the United States enacted and implemented 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 that had already been granted. The patent laws and regulations may change in unpredictable ways through actions of the U.S. Congress, the federal courts, and the U.S. PTO, in the future, and any changes may adversely affect our ability to obtain new patents or to enforce our existing patents and patents that we might obtain in the future.

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

Filing, prosecuting, and defending patents on products 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 may export otherwise infringing products to territories where we have patent protection, but enforcement is not as strong as in the United States. These products may compete with our products, 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.

***Intellectual property rights do not address all potential threats to any competitive advantage we may have.***

The degree of future protection afforded by our intellectual property rights is uncertain because intellectual property rights have limitations, and intellectual property rights may not adequately protect our business or permit us to maintain our competitive advantage. The following examples are illustrative:

● Others may be able to make products that are the same as or similar to our current or future products but that are not covered by the claims of the patents that we own or have exclusively licensed.

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

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

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

● The prosecution of our pending patent applications may not result in granted patents.

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

● Patent protection on our products may expire before we are able to develop and commercialize the product, or before we are able to recover our investment in the product.

● Our competitors might conduct research and development activities in the United States and other countries that provide a safe harbor from patent infringement claims for such activities, as well as in countries in which we do not have patent rights, and may then use the information learned from such activities to develop competitive products for sale in markets where we intend to market our products.

**Risks Related to the Ownership of our Ordinary Shares**

***The market price of our ordinary shares may be highly volatile.***

The trading price of our ordinary shares has been, and is likely to continue to be, volatile. The following factors, some of which are beyond our control, in addition to other risk factors described in this Annual Report may have a significant impact on the market price of our ordinary shares:

● adverse results or delays in preclinical studies or clinical trials;

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

● inability to obtain additional funding;

● any delay in filing a regulatory submission for any of our products and any adverse development or perceived adverse development with respect to the FDA's review or European authorities' review of that regulatory submission;

● failure to develop successfully and commercialize our products or product candidates and future products;

● failure to enter into or maintain strategic collaborations;

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

● changes in laws or regulations applicable to future products;

● inability to scale up our manufacturing capabilities, inability to obtain adequate product supply for our products, or the inability to do so at acceptable prices;

● adverse regulatory decisions, including by the IIA under the Innovation Law;

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

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

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

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

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

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

● additions or departures of key scientific or management personnel;

● significant lawsuits, including patent or shareholder litigation;

● changes in the market valuations of similar companies;

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

● trading volumes of our ordinary shares.

In addition, companies trading in the stock market in general, and life science 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. In the past, following periods of volatility in the market price of a company's securities, securities class action litigation has often been instituted against that company. If we were involved in any similar litigation, we could incur substantial costs and our management's attention and resources could be diverted, which could affect our business, financial condition and results of operations.

***We may not be able to maintain our listing on the Nasdaq Global Market.***

Our ordinary shares currently trade on the Nasdaq Global Market under the symbol "CLGN". If we fail to adhere to Nasdaq's strict listing criteria, including with respect to share price, market capitalization and stockholders' equity, our stock may be delisted. Our results of operations and our fluctuating stock price directly affects our ability to satisfy these listing standards. If we fail to do so, we may be subject to delisting. A delisting could adversely affect our ability to obtain financing for our operations or result in a loss of confidence by investors, customers, suppliers or employees. A delisting from the Nasdaq Global Market could result in our ordinary shares being listed on the Nasdaq Capital Market or on an over-the-counter market, each of which are generally considered to be a less efficient market than the Nasdaq Global Market. A delisting could adversely affect our ability to obtain financing for our operations or result in a loss of confidence by investors, customers, suppliers or employees. Although we currently satisfy the listing criteria for Nasdaq, if our stock price declines dramatically, we could be at risk of failing to meet the Nasdaq continued listing criteria.

 ****

***We incur significant additional costs as a result of being a public company subject to SEC reporting requirements in the United States, and our management is required to devote substantial additional time to new compliance initiatives as well as to compliance with ongoing United States reporting requirements.***

As a U.S. public reporting company, we are incurring significant additional accounting, legal, and other expenses in the future. Our management and other personnel need to devote substantial time to the compliance requirements of being a U.S. public company; in addition, the implementation of such compliance processes and systems may require us to hire outside consultants and incur other significant costs. Any future changes in the laws and regulations affecting public companies in the United States and the rules and regulations adopted by the SEC and the Nasdaq Global Market, for so long as they apply to us, will result in increased costs to us as we respond to such changes. These laws, rules, and regulations could make it more difficult or more costly for us to obtain certain types of insurance, including director and officer liability insurance, and we may be forced to accept reduced policy limits and coverage or incur substantially higher costs to obtain the same or similar coverage. The impact of these requirements could also make it more difficult for us to attract and retain qualified persons to serve on our board of directors, on our board committees, if any, or as senior management.

***Our principal shareholders, management and directors beneficially own a significant percentage of our ordinary shares and will be able to exert significant influence over matters subject to shareholder approval.***

As of March 15, 2023, our senior management, directors, and five percent or more shareholders and their affiliates beneficially owned approximately 36.1% of our ordinary shares. These shareholders will be able to significantly influence all matters requiring shareholder approval, except for decisions that require a special majority at a shareholders' meeting. For example, these shareholders, if they were to act together, may be able to significantly influence elections of directors (other than our external directors, within the meaning of Israeli law, as described under "Management—External 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.

***If we fail to maintain an effective system of internal control over financial reporting, we may not be able to accurately report our financial results or prevent fraud. As a result, our shareholders could lose confidence in our financial and other public reporting, which would harm our business and the trading price of our ordinary shares.***

Effective internal controls over financial reporting are necessary for us to provide reliable financial reports. Together with adequate disclosure controls and procedures, effective internal controls are designed to prevent fraud. Any failure to implement required new or improved controls or difficulties encountered in their implementation could cause us to fail to meet our reporting obligations. In addition, any testing by us conducted in connection with Section 404 of the Sarbanes-Oxley Act of 2002, or the Sarbanes-Oxley Act, may reveal deficiencies in our internal controls over financial reporting that are deemed to be material weaknesses, may require prospective or retroactive changes to our financial statements, or may identify other areas for further attention or improvement. Inferior internal controls could also cause investors to lose confidence in our reported financial information, which could have a negative effect on the trading price of our ordinary shares.

We are required to disclose changes made in our internal controls and procedures on an annual basis and our management is required to assess the effectiveness of these controls annually. However, for as long as we are an "emerging growth company" under the Jumpstart Our Business Startups Act, or the JOBS Act, our independent registered public accounting firm will not be required to attest to the effectiveness of our internal controls over financial reporting pursuant to Section 404 of the Sarbanes-Oxley Act. We could be an emerging growth company for up to the date that is the last date of the fiscal year that includes the fifth anniversary of our first sale of our common equity securities pursuant to an effective registration statement (i.e. December 31, 2023). An independent assessment of the effectiveness of our internal controls could detect problems that our management's assessment might not. Undetected material weaknesses in our internal controls could lead to financial statement restatements and require us to incur the expense of remediation.

***We are an "emerging growth company" and a "foreign private issuer," and we cannot be certain if the reduced reporting requirements applicable to emerging growth companies and foreign private issuers will make our ordinary shares less attractive to investors.***

We are an "emerging growth company," as defined in the JOBS Act. While we currently qualify as an "emerging growth company" under the JOBS Act, we will cease to be an emerging growth company on or before December 31, 2023, and at such time our costs and the demands placed upon our management are expected to increase. For as long as we continue to be an emerging growth company, we may take advantage of exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies, including not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in this Annual Report on Form 20-F and other periodic reports and proxy statements, extended transition periods for adopting new or revised accounting standards, and exemptions from the requirements of holding a non-binding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved. We will be an emerging growth company until the earliest of: (i) the last day of the fiscal year during which we had total annual gross revenues of $1.235 billion or more, (ii) the last day of the fiscal year following the fifth anniversary of the date of the first sale of our common equity securities pursuant to an effective registration statement (i.e. December 31, 2023), (iii) the date on which we have, during the previous three-year period, issued more than $1 billion in non-convertible debt or (iv) the date on which we are deemed a "large accelerated filer" as defined in Regulation S-K under the Securities Act, which means the market value of our ordinary shares that is held by non-affiliates exceeds $700 million as of the prior June 30<sup>th</sup>. Furthermore, as a foreign private issuer, we are not subject to the same requirements that are imposed upon U.S. domestic issuers by the SEC. Under the Securities Exchange Act of 1934, as amended, or the Exchange Act, we will be subject to reporting obligations that, in certain respects, are less detailed and less frequent than those of U.S. domestic reporting companies. For example, we will not be required to issue proxy statements that comply with the requirements applicable to U.S. domestic reporting companies. We will also have four months after the end of each fiscal year to file our Annual Reports with the SEC and will not be required to file current reports as frequently or promptly as U.S. domestic reporting companies. Furthermore, our officers, directors, and principal shareholders will be exempt from the requirements to report transactions in our equity securities and from the short-swing profit liability provisions contained in Section 16 of the Exchange Act. These exemptions and leniencies, along with other corporate governance exemptions resulting from our ability to rely on home country rules, will reduce the frequency and scope of information and protections to which you may otherwise have been eligible in relation to U.S. domestic reporting companies. See "Item 16G. Corporate Governance Practices" for more information.

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.

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

If our existing shareholders sell, indicate an intention to sell, or the market perceives that they intend to sell, substantial amounts of our securities on the Nasdaq Global Market after the date of this Annual Report on Form 20-F, the market price of our securities could decline significantly. As of March 15, 2023, we had 11,385,041 ordinary shares outstanding.

In addition, as of March 15, 2023, an aggregate of 1,267,177 ordinary shares, that are issuable pursuant to exercise of either outstanding options or outstanding warrants, will become eligible for sale in the public market to the extent permitted by the provisions of various vesting schedules, and Rule 144 and Rule 701 under the Securities Act of 1933, as amended, or the Securities Act. If these additional ordinary shares are sold, or if it is perceived that they will be sold, in the public market, the market price of our ordinary shares could decline.

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

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

Pursuant to our Share Ownership and Option Plan (2010), or the 2010 Plan, our management is authorized to grant share options and other equity-based awards to our employees, directors, and consultants. As of March 15, 2023, our officers, directors, employees and consultants hold options to purchase 1,844,652 ordinary shares under the 2010 Plan.

If our board of directors elects to increase the number of shares available for future grant by the maximum amount each year, our shareholders may experience additional dilution, which could cause our share price to fall.

***We do not intend to pay dividends on our securities 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; see "Item 10.B. Memorandum and Articles of Association—Dividend and Liquidation Rights" for additional information. As a result, investors in our ordinary shares will not be able to benefit from owning these securities unless their market price becomes greater than the price paid by such investors and they are able to sell such securities. We cannot assure you that you will ever be able to resell our securities at a price in excess of the price paid.

***Your percentage ownership in us may be diluted by future issuances of share capital, which could reduce your influence over matters on which shareholders vote.***

Our board of directors will have the authority, in most cases without action or vote of our shareholders, to issue all or any part of our authorized but unissued shares, including ordinary shares issuable upon the exercise of outstanding options and warrants. Issuances of additional shares would reduce your influence over matters on which our shareholders vote.

***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 will rely 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 if one or more securities analysts downgrade our ordinary shares, issue other unfavorable commentary, or cease publishing reports about us or our business.

**Risks Related to Our Operations in Israel**

***We are a "foreign private issuer" and intend to follow certain home country corporate governance practices, and our shareholders may not have the same protections afforded to shareholders of companies that are subject to all corporate governance requirements under the listing rules of the Nasdaq Stock Market LLC, or the Nasdaq Listing Rules.***

As a foreign private issuer, we are permitted 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 follow home country practice in Israel with regard to the quorum requirement for shareholder meetings. As permitted under the Israeli Companies Law of 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 20% of the voting power of our shares. In addition, we will 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 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, and certain acquisitions of the stock or assets of another company). We may in the future (or may be required to) elect to follow home country practices in Israel with regard to other matters. 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 Listing Rules applicable to domestic U.S. issuers. See "Item 16G. Corporate Governance Practices" for more information.

In addition, as a foreign private issuer, we are exempt from the rules and regulations under the Exchange Act related to the furnishing and content of proxy statements, including the requirement for an emerging growth company to disclose the compensation of the chief executive officer and other two highest compensated executive officers on an individual, rather than aggregate, basis. Under regulations promulgated under the Companies Law, we will be required to disclose in the notice for our annual meetings of shareholders if we had not already done so in our annual report, the annual compensation of our five most highly compensated officers on an individual basis, rather than aggregate. However, this disclosure will not be as extensive as the disclosure required by a U.S. domestic issuer. We will also have four months after the end of each fiscal year to file our annual reports with the SEC and will not be required to file current reports as frequently or promptly as U.S. domestic reporting companies. Furthermore, as a foreign private issuer, our officers, directors and principal shareholders will be exempt from the requirements to report short-swing profit recovery contained in Section 16 of the Exchange Act. Also, as a foreign private issuer, we are not subject to the requirements of Regulation FD (Fair Disclosure) promulgated under the Exchange Act. These exemptions and leniencies will reduce the frequency and scope of information and protections available to you in comparison to those applicable to U.S. domestic reporting companies.

In order to maintain our current status as a foreign private issuer, more than 50% of our outstanding voting securities must not be directly or indirectly owned by residents of the U.S., and we must not have any of the following: (i) a majority of our executive officers or directors being U.S. citizens or residents, (ii) more than 50% of our assets being located in the U.S., or (iii) our business being principally administered in the U.S. Although we have elected to comply with certain U.S. regulatory provisions, our loss of foreign private issuer status would make such provisions mandatory. The regulatory and compliance costs to us under U.S. securities laws as a U.S. domestic reporting company may be significantly higher. If we are not a foreign private issuer, we will be required to file periodic reports and registration statements on U.S. domestic reporting company forms with the SEC, which are more detailed and extensive than the forms available to a foreign private issuer. We may 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.

***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 impact our results of operations.***

We are incorporated under Israeli law and our offices and operations are located in the State of Israel. In addition, our employees, officers, and all but 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 adversely impact our operations. Since October 2000, there have been increasing occurrences of terrorist violence. Ongoing and revived hostilities or other Israeli political or economic factors could harm our operations, product development and results of operations.

Although Israel has entered into various agreements with Egypt, Jordan, and the Palestinian Authority, there has been an increase in unrest and terrorist activity, which began in October 2000 and has continued with varying levels of severity. The establishment in 2006 of a government in the Gaza Strip by representatives of the Hamas militant group has created additional unrest and uncertainty in the region. In 2006, a conflict between Israel and the Hezbollah in Lebanon resulted in thousands of rockets being fired from Lebanon up to 50 miles into Israel. Starting in December 2008, for approximately three weeks, Israel engaged in an armed conflict with Hamas in the Gaza Strip, which involved missile strikes against civilian targets in various parts of Israel and negatively affected business conditions in Israel. In November 2012, for approximately one week, Israel experienced a similar armed conflict, resulting in hundreds of rockets being fired from the Gaza Strip and disrupting most day-to-day civilian activity in southern Israel. Most recently, in May 2021, Israel yet again experienced rocket strikes against civilian targets in various parts of Israel, as part of an armed conflict commenced between Israel and Hamas. If continued or resumed, these hostilities may negatively affect business conditions in Israel in general and our business in particular. Our insurance policies do not cover us for the damages incurred in connection with these conflicts or for any resulting disruption in our operations. The Israeli government, as a matter of law, provides coverage for the reinstatement value of direct damages that are caused by terrorist attacks or acts of war; however, the government may cease providing such coverage or the coverage might not be enough to cover potential damages. In the event that hostilities disrupt the ongoing operation of our facilities or the airports and seaports on which we depend to import and export our supplies and products, our operations may be materially adversely affected.

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

Popular uprisings in various countries in the Middle East and North Africa are affecting the political stability of those countries. Such instability may lead to deterioration in the political and trade relationships that exist between the State of Israel and these countries. Several countries, principally in the Middle East, still restrict doing business with Israel and Israeli companies, and additional countries may impose restrictions on doing business with Israel and Israeli companies if hostilities in Israel or political instability in the region continues or increases. Any hostilities involving Israel, 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.

In addition, Iran has threatened to attack Israel and is widely believed to be developing nuclear weapons. Iran is also believed to have a strong influence among extremist groups in the region, such as Hamas in Gaza, Hezbollah in Lebanon, and various rebel militia groups in Syria. Additionally, a violent jihadist group named Islamic State of Iraq and Levant, or ISIL, is involved in hostilities in Iraq and Syria. Although ISIL's activities have not directly affected the political and economic conditions in Israel, ISIL's stated purpose is to take control of the Middle East, including Israel. These situations may potentially escalate in the future to more violent events, which may affect Israel and us. Any armed conflicts, terrorist activities, or political instability in the region could adversely affect business conditions and could harm our results of operations and could make it more difficult for us to raise capital. Parties with whom we do business may decline to travel to Israel during periods of heightened unrest or tension, forcing us to make alternative arrangements when necessary in order to meet our business partners face to face. In addition, the political and security situation in Israel may result in parties with whom we have agreements involving performance in Israel claiming that they are not obligated to perform their commitments under those agreements pursuant to force majeure provisions in such agreements. Further, in the past, the State of Israel and Israeli companies have been subjected to economic boycotts. Several countries still restrict business with the State of Israel and with Israeli companies. These restrictive laws and policies may have an adverse impact on our operating results, financial condition, or the expansion of our business.

The legislative power of the State resides in the Knesset, a unicameral parliament that consists of 120 members elected by nationwide voting under a system of proportional representation. Israel's most recent general elections were held on April 9, 2019, September 17, 2019, March 2, 2020 March 23, 2021 and November 1, 2022. Furthermore, the Israeli government has recently been pursuing legislative changes which, if adopted, may alter the current state of separation of powers among the three branches of government and, as a result, have sparked a considerable political debate. In response to the foregoing developments, many individuals, organizations and institutions, within and outside of Israel, have voiced concerns over the potential negative impacts of such changes and the controversy surrounding them on the business and financial environment in Israel. Such negative impacts may include, among others, a downgrade in Israel's sovereign credit rating, increased interest rates, currency fluctuations, inflation, civil unrest and volatility in securities markets, which could adversely affect the conditions in which we operate in Israel and potentially deter foreign investors and organizations from investing or transacting business in Israel. If any of the foregoing risks were to materialize, it may have an adverse effect on our business, our results of operations and our ability to raise additional funds.

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

As of March 15, 2023, we had 73 employees, all of whom were based in Israel. Some of our employees may be called upon to perform up to 36 days (and in some cases more) of annual military reserve duty until they reach the age of 40 (and in some cases, up to 45 or older) and, in emergency circumstances, could be called to immediate and unlimited active duty. In the event of severe unrest or other conflict, individuals could be required to serve in the military for extended periods of time. Since September 2000, in response to increased tension and hostilities, there have been occasional call-ups of military reservists, including in connection with the 2006 conflict in Lebanon, and the December 2008, November 2012 and, July 2014 conflicts with Hamas, and it is possible that there will be additional call-ups in the future. Our operations could be disrupted by the absence of a significant number of our employees related to military service or the absence for extended periods of one or more of our key employees for military service. Such disruption could materially adversely affect our business and results of operations. Additionally, the absence of a significant number of the employees of our Israeli suppliers and contractors related to military service or the absence for extended periods of one or more of their key employees for military service may disrupt their operations.

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

If and when we generate taxable income, we may be eligible for certain tax benefits provided to "Preferred Enterprises" under the Israeli Law for the Encouragement of Capital Investments, 5719-1959, as amended, or the Investment Law. The benefits that may be available to us under the Investment Law are subject to the fulfillment of conditions stipulated in the Investment Law. 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 currently 23%. 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 10.E. 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 Annual Report on Form 20-F 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, research facilities and substantially all of our operations are located in Israel. All of our senior management and a majority of our directors are located outside the United States. All of our assets 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 by expert witnesses, which can be a time-consuming and costly process. Certain matters of procedure would 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 of fairness towards the company. 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.C. Board Practices—Approval of Related Party Transactions under Israeli Law—Shareholders' Duties."

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

Israeli law regulates mergers, requires tender offers for acquisitions of shares above specified thresholds, requires special approvals for transactions involving directors, officers, or significant shareholders and regulates other matters that may be relevant to such types of transactions. For example, a tender offer for all of a company's issued and outstanding shares, or a Full Tender Offer, can only be completed if the acquirer receives approval of the holders of at least 95% of the issued share capital. Completion of the Full 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 Full 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. In case the Full Tender Offer has not been accepted by the required threshold, the offeror is limited to acquire shares that will confer on the offeror a holding of not more than 90% of the issued share capital of the company. In addition, special tender offer requirements may also apply upon a purchaser becoming a holder of 25% or more of the voting rights in a company (if there is no other shareholder of the company holding 25% or more of the voting rights in the company) or upon a purchaser becoming a holder of more than 45% of the voting rights in the company (if there is no other shareholder of the company who holds more than 45% of the voting rights in the company), See "Item 10.B. 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 fulfilment 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.

We have received grants from the IIA for certain research and development expenditures. The terms of these grants may require us to satisfy specified conditions in order to manufacture products and transfer technologies outside of Israel. For more information, see "—Risks Related to Our Financial Condition and Capital Requirements—The IIA grants we have received for research and development expenditures may restrict our ability to manufacture products and transfer know-how outside of Israel and require us to satisfy specified conditions."

***We may be classified as a passive foreign investment company for U.S. federal income tax purposes, and our U.S. shareholders may suffer adverse tax consequences as a result.***

Generally, if, for any taxable year, either, at least 75% of our gross income is passive income (including our pro-rata share of the gross income of our 25% or more-owned corporate subsidiaries), or at least 50% of the average value of our assets (including our pro-rata share of the assets of our 25% or more-owned corporate subsidiaries) is attributable to assets that produce passive income or are held for the production of passive income, we would be characterized as a passive foreign investment company, or PFIC, for U.S. federal income tax purposes. Passive income generally includes dividends, interest, and gains from disposition of passive assets and rents and royalties.

If we are characterized as a PFIC for any taxable year (or portion thereof) that is included in the holding period of a U.S. holder (as defined below) of our securities, such U.S. holder generally will be subject to certain adverse U.S. federal income tax consequences, including increased tax liability on gains from dispositions of our securities and certain distributions and a requirement to file annual reports with the Internal Revenue Service, or IRS. See "Item 10.E. Taxation—Material U.S. Federal Income Tax Consequences—Passive Foreign Investment Company Consequences."

Since PFIC status depends on the composition of our income and the composition and value of our assets (which may be determined in large 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. However, based on our non-passive revenue-producing operations for the year ended December 31, 2022, we do not believe we were a PFIC for our 2022 taxable year. Because the PFIC determination is highly fact intensive, there can be no assurance that we were not a PFIC in 2022 and will not be a PFIC in 2023 or any other year.

U.S. investors are urged to consult their own tax advisors regarding the possible application of the PFIC rules. For more information, see "Item 10.E. Taxation—Material U.S. Federal Income Tax Consequences—Passive Foreign Investment Company Consequences."

***If a United States person is treated as owning at least 10% of our shares, such holder may be subject to adverse U.S. federal income tax consequences.***

 ****

If a United States person is treated as owning (directly, indirectly or constructively) at least 10% of the value or voting power of our shares, such person may be treated as a "United States shareholder" with respect to each "controlled foreign corporation" in our group (if any). A United States shareholder of a controlled foreign corporation may be required to annually report and include in its U.S. taxable income its pro rata share of "Subpart F income," "global intangible low-taxed income" and investments in U.S. property by controlled foreign corporations, whether or not we make any distributions, and may be subject to tax reporting obligations. An individual that is a United States shareholder with respect to a controlled foreign corporation generally would not be allowed certain tax deductions or foreign tax credits that would be allowed to a United States shareholder that is a U.S. corporation. A failure to comply with these reporting obligations may subject you to significant monetary penalties and may prevent the statute of limitations with respect to your U.S. federal income tax return for the year for which reporting was due from starting. We cannot provide any assurances that we will assist any shareholder in determining whether such shareholder is treated as a United States shareholder with respect to any "controlled foreign corporation" in our group (if any) or furnish to any United States shareholders information that may be necessary to comply with the aforementioned reporting and tax paying obligations. A United States investor should consult its tax advisors regarding the potential application of these rules to its investment in the shares.

***Our facilities in Israel are subject to local Business Licensing and Planning and Zoning regulations and we may be subject to fines if not complied with.***

Under the Israeli Licensing of Businesses Law, to which our production site and offices and laboratories are subject, operating a business without a license or temporary permit is a criminal offense. In April 2019, we moved our laboratories and offices to a new site in Rehovot, Israel, and in the third quarter of 2020 we obtained two business licenses for our sites in Rehovot, which are in effect until December 31, 2025 and December 31, 2030, respectively. In addition, we have a business license for our plant growth and production site at Yessod Hama'ala, Israel, which is in effect until July 18, 2025. We intend to apply to extend our business license for our site at Yessod Hama'ala, Israel.

In addition, our production sites and laboratories are subject to the Israeli Planning and Zoning Law, which sets provisions and obligations, *inter alia*, regarding the licensing process for a new building, including building permits, non-conforming use and easements, the supervision over its construction, and the required occupancy permits. According to the Planning and Zoning Law, work or use of land without a permit, where such permit is required, a deviation from the permit granted, or use of agricultural land in violation of the law constitute criminal offenses.

**ITEM 4. INFORMATION ON THE COMPANY**

&nbsp;&nbsp;&nbsp;&nbsp;**A.** **History and Development of the Company** 

We are a regenerative and aesthetic medicine company focused on 3D bioprinting of tissues and organs, and medical aesthetics. Our products are based on our rhCollagen that is produced with our proprietary plant based genetic engineering technology. Our products address indications for the diverse fields of tissue repair, aesthetics and organ manufacturing, and, we believe, are ushering in a new era in regenerative and aesthetic medicine. Our collaborations include, among others, AbbVie, STEMCELL, Tel Aviv University, Sheba Medical Center, ARMI and ReMDO.

Our flagship rhCollagen BioInk product line is ideal for 3D bioprinting of tissues and organs. We are developing 3D bioprinted breast implants for regeneration of breast tissue and aim to provide a revolutionary alternative to the current practices. The implants in development will be bioprinted and loaded with compositions that are based on rhCollagen and ECM components. These implants are intended to promote tissue regeneration and degrade in synchronization with the development of a natural breast tissue.

In February 2021, we entered into a Development, Exclusivity and Option Products Agreement with AbbVie, pursuant to which we and AbbVie will collaborate in the development and commercialization of dermal and soft tissue filler products for the medical aesthetics market, using our rhCollagen technology and AbbVie's technology. To date, the development of the product continues to move forward according to plan.

In October 2021, we announced that our rhCollagen based Bioink was used successfully by researchers from Israel's Technion Institute of Technology to create a 3D bioprinted implantable tissue containing a network of blood vessels capable of supplying blood to the implanted tissue.

In November 2022 we launched Collink.3D 90, an rhCollagen-based bioink solution for use in a variety of 3D bioprinting applications, offering increased mechanical properties to address additional printing requirements of soft and hard tissues. Collink.3D™ 90 is complementary to our first commercial bioink, Collink.3D 50, which was launched in November 2021, for use in 3D bioprinting. Collink.3D 50, our first commercially available rhCollagen-based bioink product is designed to allow the scalable and reproduceable biofabrication of scaffolds, tissues and organ transplants. Made entirely from human-derived collagen, Collink.3D bioinks enables the production of scaffolds that accurately mimic the physical properties of human tissues and organs, with improved bio-functionality, safety and reproducibility.

Also in November 2022, we entered into a license and research agreement with Tel Aviv University and Sheba Medical Center hospital, to co-develop a 'Gut-on-a-Chip' tissue model for drug discovery and high throughput screening of drugs. The model is intended to be used in personal medicine applications for the treatment of ulcerative colitis, an inflammatory bowel disease affecting millions of individuals worldwide.

In January 2023, we launched Collink.3D™ 50L in powder form, which is our first bioink available in powder form and provides enhanced operational flexibility to support a wide range of 3D bioprinting applications, including drug discovery, drug screening, tissue testing as well as the development of transplantable tissues and organs.

Previously, in December 2020, we entered into a product manufacturing and supply agreement with STEMCELL. As part of the agreement, we are selling our proprietary recombinant human Type I collagen (rhCollagen) to STEMCELL, which incorporates our product into cell culture media kits. To date, hundreds of companies, as well as research and academic institutes, have used these kits for research and development projects. STEMCELL is distributing the kits globally for use in the regenerative medicine research market.

We believe our technology is the only commercially viable technology available for the production of genetically engineered, or recombinant, human collagen. We believe that our rhCollagen, though laboratory-derived, is identical to the type I collagen produced by the human body, has significant advantages compared to currently marketed collagens, known as "tissue-derived collagens", that are extracted from animals and human cadavers. Our advantages include improved biological function, high homogeneity, and reduced risk of immune response. We believe the attributes of our rhCollagen make it suitable for numerous tissue repair applications throughout the human body. We believe that the annual market size for our BioInk, and our medical aesthetics product candidates including dermal filler, exceeded $10 billion in 2021, and is estimated to reach $18 billion in 2026.

Our rhCollagen has superior biological function when compared to any tissue-derived collagens, whether from animal or human tissues, according to data published in peer-reviewed scientific publications. Our rhCollagen can be fabricated in different forms and shapes including gels, pastes, sponges, sheets, membranes, fibers, and thin coats, all of which have been tested and proven superior to tissue-derived products. We have demonstrated that, due to its homogeneity, rhCollagen can produce fibers and membranes with high molecular order, meaning there is high molecular alignment, which enables the formation of tissue repair products with distinctive physical properties. We produce our rhCollagen from genetically engineered tobacco plants, assuring a relatively abundant supply of high-quality raw materials.

We are currently focusing on the following two rhCollagen-based family products lines:

●  ***CollPlant rhCollagen-based BioInk for use in the 3D printing of tissues and organs.*** Our flagship BioInk product line provides an ideal building block for three dimensional bioprinting of tissues and organs. The BioInk is being developed to enable the printing of three-dimensional scaffolds combined with human cells and/or growth factors as a basis for tissue or organ formation. In addition to collagen, CollPlant's BioInk formulations can include other proteins and/or polymers as well. Our BioInk is being developed to be compatible with numerous 3D bioprinting technologies and with printed organ characteristics. We are developing a bioprinted regenerative breast implants, which are designed to gradually degrade and be replaced by newly grown natural breast tissue. We are also developing a regenerative soft tissue matrix. Both the bioprinted breast implants and soft tissue matrix programs are currently in the pre-clinical phase, and we plan to initiate a second large animal study for the breast implant product in the second half of 2023. We are also developing with Tel Aviv University and Sheba Medical Center hospital, a 'Gut-on-a-Chip' tissue model for drug discovery and high throughput screening of drugs. Designed to emulate the human intestine tissue, the 3D bioprinted model will allow medical professionals to identify drug targets and personalized therapeutic responses that can lead to improved patient outcomes.

●  ***Aesthetic medicine product line including a dermal filler and breast implants.*** Our rhCollagen offers a portfolio of opportunities in the field of regenerative aesthetics, owing to its ideal structure and non-immunogenic properties that provide, what we believe is the optimal scaffold to attract cells and promote tissue regeneration. In February 2021, we entered into a Development, Exclusivity and Option Products Agreement with AbbVie, pursuant to which we and AbbVie are collaborating in the development and commercialization of dermal and soft tissue filler products for the medical aesthetics market, using our rhCollagen technology and AbbVie's technology. In addition, we are developing a photocurable regenerative dermal filler combining our tissue regenerating rhCollagen and other technologies which is designed to address the need for more innovative aesthetic products to treat wrinkles. AbbVie has a right of first negotiation for the photocurable regenerative dermal filler. In addition, we are developing an injectable breast implant for regeneration of breast tissue comprised of rhCollagen and additional materials. AbbVie has a right of first negotiation for the injectable breast implant product candidate.

We also currently market two of our products in Europe: VergenixSTR, a soft tissue matrix, intended to accelerate treatment of tendinopathy, and VergenixFG, a wound healing flowable gel, intended to enhance the quality and speed of closure of deep surgical incisions and wounds.

**Collagen and Collagen-Based Products**

Collagen is the main component of connective tissue and is the most abundant protein in mammals. In humans, it comprises approximately 30% of the protein found in the body. Due to its unique characteristics and diverse profile in human body functions, collagen is frequently selected from a variety of biocompatible materials for use in tissue repair to support structural integrity, induce cellular infiltration and promote healing. We estimate that the size of the market for human collagen-based tissue repair with our BioInks and aesthetic medicine product line exceeded $10 billion in 2021 and is estimated to reach approximately $18 billion in 2026.

Type I collagen is the most abundant form of collagen in the human body. It is the dominant constituent of connective tissue and serves as the primary scaffold in tissue or organ repair processes, making it a logical choice for regenerative medicine products. It is found in tendons, skin, artery walls, corneas, the endomysium surrounding muscle fibers, fibrocartilage, and the organic part of bones and teeth. Type II collagen is primarily found in articular cartilage. Type III collagen, which is produced quickly by young fibroblasts before the tougher type I collagen is synthesized, is found in granulation tissue such as artery walls, skin, intestines, and the uterus. While there may be some niche applications in the future where type III or possibly type II collagen is appropriate, type I collagen is best suited for applications associated with regenerative medicine because of its essential role in the healing process of bones, skin, and tendons. Type III rhCollagen is currently available for the research market, and is not used in any products currently approved for medical use.

***Disadvantages of Current Collagen-Based Products***

Currently, type I collagen for medical use is primarily tissue-derived from bovine (cow) and porcine (pig) sources, as well as from human cadavers. It is extracted from the tissues using mechanical processes and chemical treatments. Tissue-derived collagens suffer from a number of disadvantages:

● The harsh chemical conditions required to recycle collagen from mature tissue results in a collagen product with random defects in its protein structure, leading to a compromised triple helix. Consequently, tissue-derived collagens have significant damage to binding sites for progenitor cells, which are required for cell proliferation and differentiation into tissue.

● Tissue-derived collagens are non-homogenous and contains high proportions of cross-linked collagen species with high molecular weight. The rate of degradation of collagen is based on the proportion of cross-linked collagen species within the product. Excessive proportions of cross-linked collagen can impair the collagen's ability to self-assemble homogenous scaffolds with a high surface area and fully functional integrin-binding capacity, and can also impede its rate of degradation. The inability to effectively control the level of cross-linked collagen species in tissue-derived collagens results in variability of performance for a given product, and affects the rate of infiltration of cells into the scaffold, which can delay healing.

● The extraction of collagen from mature mammalian tissues leaves, in many cases, contaminant proteins, growth factors, and cytokines. As a result, scaffolds made of tissue-derived collagens may provoke inflammation, as well as undesirable immune and foreign body responses that may cause adverse effects and unpredictable biological outcomes.

● Extraction from animals or humans is also associated with risk of disease transmission. Since 2007, the FDA has highlighted the risks of transmissible diseases to humans in medical devices that contain materials derived from animal sources. In January 2014, the FDA released draft guidance suggesting precautionary procedures to be used in the production of medical devices containing materials derived from animal sources.

● Although collagen molecules are similar among various animal species, slight differences in the protein sequence between species may result in different biological behavior when applied to humans, and in some cases, invoke specific immune responses; for example, bovine collagen is associated with hypersensitivity and allergic reactions in approximately 3% of people.

**Advantages of our rhCollagen and rhCollagen-based Products**

All of our products are based on our proprietary recombinant type I human collagen, rhCollagen, though laboratory-derived, is identical to the type I collagen produced by the human body. The graphic below illustrates the structural differences between rhCollagen produced with our proprietary plant-based technology and currently marketed tissue-derived collagens.

![](image_001.jpg)

The key advantages of products using our rhCollagen, as compared to those using collagen derived from animals or human cadaveric tissue, include:

●  ***Better biofunctionality in tissue regeneration.*** Our rhCollagen has superior biological function when compared to animal or human tissue-derived collagen and has a number of useful physical characteristics, including thermal stability, or resistance to decomposition at high temperatures, and a pristine triple helix, according to data published in peer-reviewed scientific publications. The triple helix structure of collagen is formed when two *α* -1 protein chains and one *α-* 2 protein chain wind together along a common axis. In the formation of rhCollagen, this structure is achieved without modifications that can lead to defects in the triple helix structure in human tissue-derived collagen, hereby leading to a pristine triple helix identical to the form found in nature. A pristine triple helix enables superior binding, which accelerates primary human cell proliferation. Collagen scaffolds of our rhCollagen support endothelial, fibroblast, and keratinocyte cell attachment and proliferation. In all cell types tested, cell proliferation was significantly better in scaffolds made of rhCollagen than in commercially available scaffolds made of bovine collagen. The accelerated cell proliferation achieved with our rhCollagen results in faster wound healing, less scarring, and higher quality tissue regeneration.

●  ***High homogeneity.*** Because our rhCollagen is synthesized by five human genes in tobacco plants producing pure molecules that are repeatable and identical to type I human collagen, it is more homogenous than collagen derived from animal or human tissue sources. The high level of homogeneity of our rhCollagen allows the formulation of extremely high concentrations of monomeric, or single-molecule, collagen, up to 150-200mg/ml, which is at least 10 to 100 times higher than the concentration achieved with tissue-derived collagen. The high concentration of homogeneous monomeric collagen is of particular importance where strong collagen fibers are needed for 3-D scaffolds. The homogeneity of our rhCollagen enables us to engineer consistent and reproducible products with a controlled degradation rate which can be optimized to the targeted indication. Achieving the same level of engineered performance would be difficult, if not impossible, with tissue-derived collagen that varies from batch to batch.

●  ***Improved safety and greater purity.*** Our pure rhCollagen does not induce an immunogenic response, whereas impurities carried over from the source of tissue-derived collagen can lead to immune system rejection. *In vitro* studies performed under an academic collaboration have demonstrated that rhCollagen incubated with activated THP1-macrophages produces significantly lower levels of inflammatory cytokines when compared with bovine collagen that is similarly incubated. This demonstrates that animal-derived collagen can provoke a foreign body response not seen with rhCollagen, which delays healing and increases scarring. Further, with our rhCollagen, there are no potential side effects in the growth of tissue because there are no residues of growth factors. In addition, with tissue-derived collagen, there is a possibility that the animal or human from which the collagen was produced was infected with a virus, prion, or other pathogen. With our rhCollagen there is no known risk of transmitting diseases and pathogens.

●  ***Novel applications.*** Due to our ability to control the protein at the molecular level, it is possible to use our rhCollagen to produce products with unique physical features, as well as high repeatability, which is not possible with tissue-derived collagen. As compared to tissue-derived collagen, rhCollagen membranes have shown better thermal stability, improved tensile strength due to alignment of the collagen fibers, and higher levels of transparency. In addition, rhCollagen can be used to produce high concentration solutions of collagen at low viscosities. The unique properties of our rhCollagen make it an ideal building block for many products that we believe cannot currently be produced using tissue-derived collagen, such as BioInks for 3-D printing, artificial tendons, and transparent ophthalmic products.

We believe the clinical attributes of our rhCollagen will translate into benefits for patients, payors, and physicians, and will be adopted rapidly by the market. We believe the improved biofunctionality of our products could lead to faster recovery, better clinical outcomes, and reduced hospitalization time. Our *in vivo* studies have shown faster tissue remodeling, faster wound closure, and reduced scarring compared to competing products made from tissue-derived collagen.

The advantages of our rhCollagen outlined above have been demonstrated through *in vitro* testing and in preclinical animal studies, and are based on the performance of rhCollagen alone. The performance demonstrated in these studies is not necessarily indicative of the performance of our products which contain rhCollagen. We cannot assure you that the same advantages of rhCollagen will be seen in clinical testing of our products and product candidates containing rhCollagen.

We can produce our rhCollagen cost-effectively and have access to an abundant supply of raw materials. Tobacco is a relatively easy plant to grow, and can be cultivated in a wide range of climates and soils. The tobacco plant is an extremely hardy plant, may be grown in very large volumes and its growth time to reach desired maturity is relatively short (about eight weeks). Under our current production technology, we are able to achieve a cost of goods that allows us to offer products at prices that are competitive with tissue-derived collagen.

Collagen-based products are already used extensively in the marketplace; therefore, we expect our product candidates, except for dermal fillers, will likely be eligible for reimbursement by third-party payors, including government agencies and insurance companies. We believe that the demand for tissue-derived collagen will decrease as the market recognizes the significant advantages of our rhCollagen.

**Our Market Opportunity**

Our rhCollagen represents a platform for the development of products addressing significant opportunities in multiple therapeutic, aesthetic, and other medical markets. We are initially focused on BioInks for use in the 3D printing of tissues and organs, products that are based on our BioInks and the medical aesthetics market.

We also see a significant opportunity to use our rhCollagen platform to develop products to address additional indications in these markets as well as in new markets, including cardiovascular, orthobiologics, and ophthalmic markets. We believe that the potential addressable market opportunity for products using our technology is even greater than the market size served by currently available collagen-based products, mainly due to continued unmet medical needs and the shortcomings of tissue-derived collagen.

***BioInk for 3D printing of tissues & organs***

Regenerative medicine and tissue engineering have seen unprecedented growth in the past decade, driving the field of artificial tissue models towards a revolution in future medicine. Progress has been achieved through the development of innovative biomanufacturing strategies to pattern and assemble cells and extracellular matrix, or ECM, in three dimensions to create functional tissue constructs. Bioprinting has emerged as a promising 3D biomanufacturing technology, enabling precise control over spatial and temporal distribution of cells and ECM. Bioprinting technology can be used to engineer artificial tissues and organs by producing scaffolds with controlled spatial heterogeneity of physical properties, cellular composition, and ECM organization. This innovative approach is increasingly utilized in biomedicine, and has potential to create artificial functional constructs for drug screening and toxicology research, as well as tissue and organ transplantation.

Grand View Research Inc. estimates that the global 3D bioprinting market size was valued at $1.7 billion in 2021 and that the global market is expected to reach $5.3 billion by 2030. The growth of the global market is largely driven by increasing large demand of tissues and organs for transplantation and the innovations and advancements in technology for 3D bioprinting. A large number of people across the globe are waiting for an organ or tissue transplant, due to the large gap in demand for organ transplants and donors. This has created traction in the 3D bioprinting industry for developing live tissues and organs. Different companies along with academic institutes and laboratories are investing capital for 3D bioprinting research and development. Some of the other factors driving the growth of the global market include increasing research and development activities and increasing compliance for 3D bioprinting in drug discovery processes. Growing stem cell research and increasing adoption of 3D bioprinting in cosmetic industry are expected to create ample growth opportunities for the global market.

***Aesthetic Medicine***

 ****

Dermal fillers are gaining popularity all across the globe due to increasing trend of using anti-aging treatments, growing aging population, demand to look younger and the use of social media. According to the American Society of Plastic Surgeons, in 2020, 92% of the cosmetic procedures are performed on women, and there is rapidly gaining popularity with the male population as well. More and more companies are on the search for safer and longer lasting fillers.

Broadly, facial fillers can be divided into four categories: autologous fat, collagens, hyaluronic acid, and synthetic fillers (e.g., Calcium hydroxylapatite, Polylactic acid). In 2020, hyaluronic acid comprised the largest category of soft tissue filler injections, with approximately 77% market share and 2.6 million procedures performed in the U.S.

According to Global Market Insights Inc., global dermal filler market was valued at over $5.5 billion in 2022, and is poised to grow at a CAGR of over 10% between 2023 and 2032.

***Orthopedic and wound healing***

*Orthobiologics Market*

An aging population, active demographics, innovative technology, and emerging geographic areas are expected to continue to drive growth in the global orthopedic market. Top market segments within orthopedics include reconstructive devices, such as joint replacements; spinal implants and instruments, used to treat joint pain; fracture repair, including the use of plates and screws; and arthroscopy and soft tissue repair, primarily for sports and movement related injuries.

Chronic complex musculoskeletal injuries that are slow to heal pose challenges to physicians and patients alike. Orthobiologics use cell-based therapies and biomaterials to help injuries heal more rapidly with a superior outcome. These products are made from substances that are naturally found in the body, which dynamically interact with the musculoskeletal system to facilitate the healing of bone, cartilage, meniscus, tendons, and ligaments affected by disease or injury. Orthobiologics products are spread across all segments of the larger orthopedic market, generating much of the growth within orthopedics. The global orthobiologics market is expected to grow from $8.56 billion in 2022 to $12.33 billion by 2029, exhibiting a CAGR 5.4%.

*Advanced Wound Care Market*

The global market for wound care encompasses traditional dressings and bandages, as well as advanced wound care products such as bioengineered skin and skin substitutes and wound care growth factors. Over the past 30 years, there has been a shift from traditional wound dressings towards advanced therapies that aim to optimize the wound healing environment. Advanced wound care is composed of biocompatible products that are intended to actively promote wound healing by interacting either directly or indirectly with wound tissues. Attempts to reduce the duration of hospital stays in order to limit healthcare costs and the goal of enhancing therapeutic outcomes are driving the demand for advanced wound care and closure products. One of the primary market drivers for advanced wound care products is the increasing incidence of chronic wounds, which are on the rise due to an aging population and a sharp rise in the incidence of diabetes and obesity worldwide. Both advanced age and chronic medical conditions are associated with a slower healing process, and all phases of wound healing are affected. The inflammatory response is decreased or delayed, as is the proliferative response.

The global advanced wound care market is expected to reach $16.5 billion in 2025 from $10.3 billion in 2020. The market is estimated to grow with a CAGR of 9.8% from 2020-2025, according to MarketsAndMarkets. The three major market segments are device-based wound care, comprised of negative-pressure wound therapy and hydrosurgery systems; moist wound care, comprised of dressings that create and maintain a moist environment; and biologics, comprised of bioactive technologies that provide new approaches to debridement and dermal repair and regeneration.

**Our Strategy**

We plan to exploit the unique characteristics of our rhCollagen to develop and commercialize an extensive portfolio of regenerative medicine products, independently or in collaboration with collaboration partners. The key elements of our strategy include the following:

● **Position our rhCollagen as the "gold standard" platform technology for collagen-based products in a broad range of markets.** We believe that our rhCollagen represents a significant advance in collagen technology, demonstrated by its biofunctionality, high homogeneity, and reduced risk of immune response. Our rhCollagen is a platform technology which can be utilized in a broad range of therapeutic, aesthetic, and other medical applications, and in particular in emerging industries such as 3D bioprinting which we believe cannot be adequately addressed with currently available collagen technologies. We intend to expand the awareness of rhCollagen through partnerships and collaborations with leading commercial and academic partners around the world and further clinical trials which we will seek to have published in peer-reviewed journals, as well as through our participation in academic and industry conferences, to position rhCollagen as the "gold standard" platform technology for collagen-based products. We believe our platform technology, and the knowledge and expertise we have gained in its development, will enable the development, both independently and with collaborators, of differentiated products in multiple industries with a short time to market.

● **Utilize collaborative partners and distributors to develop and commercialize our technology and products.** We believe the market-leading characteristics of our rhCollagen will create attractive collaboration opportunities for our products, and we intend to selectively establish collaborations and strategic partnerships with respect to our current and future products in order to accelerate their development and commercialization. We established a collaboration with Allergan aesthetics, an AbbVie company and intend to engage with well-established companies whose distribution networks are deeply entrenched. We expect our commercial efforts will be comprised of the distribution networks of our collaboration partners, particularly in the United States and Europe.

● **Manufacturing capacity to support commercialization of rhCollagen-based end products.** We cultivate the tobacco plants used in the production of our rhCollagen in a network of farms in Israel, and we extract the raw materials used to manufacture our rhCollagen from these tobacco plants. We have a manufacturing facility in Israel that is supporting our current commercial needs to manufacture commercial and clinical quantities of our rhCollagen and our BioInk in a cost-competitive manner for application in both premium and commodity markets.

● **Expand our pipeline through ongoing development of new products.** We intend to continue to develop additional products, both independently and with strategic collaborators, initially in 3D bioprinting of tissues and organs, and medical aesthetics markets and subsequently in other high value markets, based on our rhCollagen. In 2019, we initiated development of injectable and 3D bioprinted breast implants. In 2021 and 2022, we developed and launched three bioink products, which are being used by customers for the development of 3D bioprinting of tissues and organs. In 2022, we entered into a co-development agreement with Tel Aviv University and Sheba Medical Center hospital for a 3D printed 'Gut-on-a-Chip' tissue model for drug discovery and high throughput screening of drugs. Our product pipeline and our research and development program are expected to yield new products in the coming years.

● **Advance our leadership position in recombinant protein production through our plant-based technology.** We continually seek to expand our knowledge of plant-based protein production systems and introduce improvements into our process. We are shifting production to an enhanced line of tobacco plants with higher collagen yield, along with improvements in the growing and cultivation process as well as collagen extraction and purification. As tissue engineering and regenerative medicine continue to evolve and expand, we expect that the demand for high-quality biomaterials will grow.

**Our Products and Product Candidates**

***BioInk for 3D printing of tissues & organs***

3D bioprinting is being applied to the field of regenerative medicine to address the need for complex scaffolds, tissues, and organs that are suitable for transplantation. We have developed rhCollagen-based BioInks that are optimized and provides an ideal building block for the three-dimensional bioprinting of tissues and organs.

For that purpose, rhCollagen was modified chemically to adapt the biological molecules for printing such that BioInks keep a controlled fluidity during printing and cure to form hydrogels when irradiated by certain light sources ranging from UV to visible light. The unique viscosity and shear thinning properties of the modified rhCollagen enable the formulation of BioInks that are suitable for different printing technologies including extrusion, ink-jet, Laser Induced Forward Transfer and Stereolithography. The control of chemical modification in combination with illumination energy allows tight control of the physical properties of the resulting scaffolds to match natural tissue properties, from stiff cartilage to soft adipose. BioInks formulated from rhCollagen were evaluated with all major currently available printing technologies and exhibited the required physical properties and excellent support for cells including a series of primary and differentiated human cells.

![](image_002.jpg)

CollPlant's BioInk based on rhCollagen - building block for tissue and organ manufacturing

We believe our BioInk offers ideal characteristics for 3D bioprinting, including:

● Biocompatibility—supports cell viability and promotes proliferation (e.g. endothelial cells, fibroblasts, keratinocytes, MSCs)

● Potential safety—has not shown to promote allergic and other tissue reactions

● Optimized viscosity and gelation kinetics—printability and compatibility with multiple printing technologies

● Curing with a range of light sources based on specific requirements

● Controlled degradation profile

● Controlled rheological properties (e.g. viscosity)

● Shear thinning properties – compatible with inkjet technology

● Convenient handling at broad range of temperatures and pH (e.g., maintains liquid properties at RT and above –no gelation)

● Compatible with different photoinitiators to cover the spectrum of 280-500nm

● Customized physical properties of the printed constructs that are compatible with natural tissues

We have initiated several research collaborations with biotechnology and medical device companies, as well as academic and research institutions. These collaborations include development of technology for 3D bioprinting of life-saving organs and different tissues, such as cornea, using our BioInk formulations. Our collaborations are generally structured such that our partners provide research funding and purchasing of our BioInk to cover the scope of work, in part or in full. This funding is typically reflected as collaboration revenues in our financial statements. Upon entering into a collaboration, we disclose the financial details only to the extent that they are material to our business and not subject to confidentiality agreements with our partners. Research collaborations with academic or research institutions typically involve both us and the academic partner contributing resources directly to projects, but also may involve sponsored research agreements where we fund specific research programs.

In November 2022, we launched Collink.3D 90, an rhCollagen-based bioink solution for use in a variety of 3D bioprinting applications, offering increased mechanical properties to address additional printing requirements of soft and hard tissues. Collink.3D™ 90 is complementary to our first commercial bioink, Collink.3D 50, which was launched in November 2021, for use in 3D bioprinting. Collink.3D 50, our first commercially available rhCollagen-based bioink product is designed to allow the scalable and reproduceable biofabrication of scaffolds, tissues and organ transplants. Made entirely from human-derived collagen, Collink.3D bioinks enables the production of scaffolds that accurately mimic the physical properties of human tissues and organs, with improved bio-functionality, safety and reproducibility.

In January 2023, we launched Collink.3D™ 50L in powder form, which is our first bioink available in powder form and provides enhanced operational flexibility to support a wide range of 3D bioprinting applications, including drug discovery, drug screening, tissue testing as well as the development of transplantable tissues and organs.

***Medical Aesthetics***

 ****

*Dermal Filler and Soft Tissue Fillers*

In February 2021, we entered into a Development, Exclusivity and Option Products Agreement, or the Development Agreement, with AbbVie, pursuant to which we and AbbVie will collaborate in the development and commercialization of dermal and soft tissue filler products for the medical aesthetics market, using our rhCollagen technology and AbbVie's technology. To date, the development of the product continues to move forward according to plan.

Pursuant to the Development Agreement, we agreed to undertake projects for the development of an aseptic process for sterile rhCollagen that meets or exceeds certain specifications as set forth in the Development Agreement. Prior to the second anniversary of the Development Agreement, AbbVie may elect to have CollPlant undertake additional projects for the development of a more concentrated rhCollagen that meets or exceeds certain specifications.

Pursuant to the Development Agreement, we granted to AbbVie and its affiliates, worldwide exclusive rights to use its rhCollagen in combination with AbbVie proprietary technologies, for the production and commercialization of dermal and soft tissue filler products, or the Exclusive Products. Further, pursuant to the Development Agreement, we granted to AbbVie and its affiliates, a right of first negotiation to enter into a definitive agreement to obtain exclusive, worldwide rights to the use of our rhCollagen for the commercialization and sale of an injectable breast implant product and a right of first negotiation to enter into a definitive agreement to obtain exclusive, worldwide rights to the use of our rhCollagen for the commercialization and sale of a photocurable dermal filler product, each an "Option Product" and together, the "Option Products". Other than under the Development Agreement, we agreed not to research, develop or commercialize its rhCollagen for use with any Exclusive Products during the term of the Development Agreement or grant any third party any rights to our rhCollagen technology that would conflict with rights granted to AbbVie.

The Development Agreement provides that later on we and AbbVie will enter into a supply agreement whereby we will manufacture and supply AbbVie with rhCollagen, at a pre-agreed price, to be used solely for the development and manufacture of the Exclusive Products and Option Products.

The Development Agreement provides that with respect to the Exclusive Products we shall be entitled to receive up to $50 million comprised of an upfront cash payment of $14 million, which was paid in February 2021, and up to $36 million in proceeds upon the achievement of certain development, clinical trial, regulatory and commercial sale milestones. In addition, CollPlant shall be entitled to a fixed-fee royalty payment (subject to certain adjustments) for each product commercially sold during the applicable royalty term as well as a fee for the supply of rhCollagen to AbbVie. In addition, with respect to the Option Products, we shall be entitled to receive up to $53 million in proceeds, including a one-time non-refundable payment, as well as milestone payments that are payable upon the achievements in certain clinical trials, regulatory approvals and commercial sale milestones, plus a fixed-fee royalty payment (subject to certain adjustments) for each product commercially sold during the applicable royalty term and a fee for the supply of rhCollagen to AbbVie.

Unless earlier terminated, the Development Agreement will continue in effect on a product-by-product and country-by-country basis until the later of (i) the expiration, invalidation or abandonment of the last CollPlant patent covering a product in a particular country, and (ii) 10 years from the first commercial sale of such product in such country. Following expiration (unless earlier terminated), the rights granted to AbbVie in the Development Agreement will continue on a non-exclusive, fully paid-up, royalty-free, perpetual and irrevocable basis. The Development Agreement may be terminated early by either party for material breach or bankruptcy. In addition, AbbVie may terminate the Development Agreement at any time immediately upon written notice to CollPlant if AbbVie reasonably believes that it is not advisable for AbbVie to continue to develop or commercialize the Exclusive Products under the Development Agreement as a result of a perceived serious safety issue regarding the use of any Exclusive Product or upon 60 days' written notice, for any or no reason, with respect to its rights under the Agreement on an Exclusive Product-by-Exclusive Product or country-by-country basis.

In addition, we are currently developing a photocurable regenerative dermal filler, which is one of AbbVie's Option Products, and is designed to address the need for more innovative aesthetic products to treat wrinkles. In this regard, we recently completed a 12-month preclinical study with our photocurable regenerative dermal filler, demonstrating superior tissue regeneration, lifting capacity and volume retention when compared to a commercial standard.

Skin rejuvenation procedures are increasing in popularity, especially nonsurgical treatments such as dermal filler injections. Hyaluronic acid is a water-retaining molecule widely used for dermal filling, but lacks the ability to promote cell proliferation and tissue regeneration. This results in a limited-lasting effect.

A photocurable version of our tissue regenerating rhCollagen, serves as the basis for a new dermal filler product line now in development. We are developing a photocurable regenerative filler comprised of rhCollagen and other substances which is intended to provide several revolutionary effects: lifting, sculpturing ability, retention to the host tissue, and tissue regeneration.

**rhCollagen-based Photocurable regenerative dermal filler key attributes:**

![](image_003.jpg)

The photocurable regenerative dermal filler is intended for injection in a semiliquid phase and hardened in-situ post injection by light illumination through the skin. Utilization of photocuring technology is expected to ease the injection process, particularly in subcutaneous and supraperiosteal applications. As the product degrades, a newly formed tissue is expected to regenerate and take its place.

According to Global Market Insights Inc., global dermal filler market was valued at over $5.5 billion in 2022, and is poised to grow at a CAGR of over 10% between 2023 and 2032, reaching up to $14.5 billion in 2032. We believe that rising awareness and acceptance regarding several cosmetic procedures in developed and developing regions, coupled with increasing disposable income, is expected to drive forward the dermal filler market size.

We believe that an expanding geriatric population across the globe seeking anti-aging and wrinkle treatment is expected to have a significant impact on segmental growth, and that an accelerating demand for numerous beauty enhancement procedures is expected to further support facial line correction segment growth.

***Breast implants***

 

Current breast reconstruction in the market is based on synthetic breast implantation and free flap surgery/autologous fat tissue transfer, all of which replace tissue rather than regenerate it. Breast augmentation and reconstruction through silicone implants, which are among the most popular surgical procedures, are associated with high risk for adverse events. Another procedure increasing in popularity for relatively small volume breast augmentation is an injectable scaffold composed of autologous fat tissue injected into the desired location for volume fill (fat transfer). The clinical outcome of this procedure is however quite limited due to a significant volume loss after a relatively short period.

We are developing 3D bioprinted breast implants and injectable breast implants for regeneration of breast tissue, aimed to overcome these challenges and provide a revolutionary alternative to the current practices.

*3D Bioprinted breast implants*

The implants in development will be bioprinted and loaded with compositions that are based on rhCollagen, autologous fat cells and ECM components. These implants are intended to promote tissue regeneration and degrade in synchronization with the development of a natural breast tissue.

The following diagram demonstrate the phases of breast implant product candidate production and implementation.

![](image_004.jpg)

In January 2023, we successfully completed a large animal study for our 3D bioprinted regenerative breast implants with full achievement of study objectives, demonstrating tissue regeneration which included the formation of maturing connective tissue and neovascular networks. The histological analysis of the implants demonstrated progressive stages of tissue regeneration after three months, as indicated by the formation of maturing connective tissues and neovascular networks. The development of native tissue was synchronized with the degradation process of the implant, which was consistent with the desired outcome observed during the trial. There was also no indication of adverse reaction noted within the implants and the surrounding tissue. We are planning to initiate a follow-up large animal study in the second half of 2023 using commercial-size implants to support subsequent human studies and future product commercialization.

 

*Injectable implants*

Injectable implants composed of rhCollagen, additional materials and fat cells taken from the patient are intended to promote breast tissue regeneration. The specific compositions are designed to support the viability and function of the autologous fat cells, and to attract cells to promote tissue regeneration. The scaffold is designed to gradually degrade and be replaced by newly grown natural breast tissue that is free of any foreign material. The injectable breast implant is one of AbbVie's Option Product.

![](image_005.jpg)

*3D bioprinted regenerative soft tissue matrix*

We are developing a 3D bioprinted regenerative soft tissue matrix for use in breast reconstruction procedures in combination with an implant. In June 2021, we signed a co-development agreement with 3D Systems for the development of the product candidate. The agreement was terminated in March 2023 and we are using printers of other companies for the development of our product candidates.

According to the World Health Organization, in 2020, approximately 2.3 million women were diagnosed with breast cancer globally. As a result, a large majority required partial or full removal of breast tissue. Survival probabilities are 90% or greater due to highly effective treatments which is increasing the focus on delivering improved options for reconstruction. The majority of breast reconstruction procedures use soft tissue matrices derived from human cadavers or animals. These sources are associated with supply shortages and batch-to-batch variability, as well as the possibility for eliciting immune response which impacts healing.

The 3D bioprinted soft tissue matrix product in development is designed to meet the required physical and mechanical properties while promoting cell infiltration and proliferation by using bioink formulations based on rhCollagen that promote tissue regeneration. We believe that the efforts will result in tissue matrices that offer superior performance, consistency and safety due to their plant origin and identical match with natural human collagen which does not elicit an adverse immune response in humans.

***Gut-on-a-Chip***

 ****

We are also developing with Tel Aviv University and Sheba Medical Center hospital, a 'Gut-on-a-Chip' tissue model for drug discovery and high throughput screening of drugs. Designed to emulate the human intestine tissue, the 3D bioprinted model the model is intended to be used in personal medicine applications for the treatment of ulcerative colitis, an inflammatory bowel disease affecting millions of individuals worldwide. The in-vitro intestine-on-chip platform combines our rhCollagen with other proprietary biomaterials and human cells. The 3D bioprinted model is intended to allow medical professionals to identify drug targets and personalized therapeutic responses that can lead to improved patient outcomes.

***Orthopedic and wound healing***

 ****

*VergenixSTR—Tendinopathy Treatment*

VergenixSTR is a soft tissue repair matrix that combines cross-linked rhCollagen with PRP, a concentrated blood plasma that contains high levels of platelets, a critical component of the healing process. Platelets contain growth factors that are responsible for stimulating tissue generation and repair, including soft tissue repair, bone regeneration, development of new blood vessels, and stimulation of the wound healing process. VergenixSTR serves as a scaffold to support cell proliferation and the release of growth factors. The product is injected into the affected area and forms a viscous gel matrix which serves as a temporary reservoir for PRP in the vicinity of a tendon injury site, holding the platelet concentrate in place at the injured area. The matrix formed has the capabilities to activate the platelets in PRP, thereby releasing growth factors in a controlled manner and controlled biodegradation time, enabling optimal healing.

In the European Union, VergenixSTR is intended for the treatment of tendinopathy by promoting healing and repair of tendon injuries in a variety of tendons including the elbow tendon (for treatment of "tennis elbow"), rotator cuffs, patellar tendons, Achilles tendon, and hand tendon.

We estimate the size of the target market for VergenixSTR for treating tendinopathy is three million procedures per year, or approximately $2.0 billion. While our initial focus for VergenixSTR is in tendinopathy, VergenixSTR may be applicable to other soft tissue indications such as tendon rupture, meniscus tear, and cartilage repair, as well as in the aesthetic market.

Globally, the aging population is playing a major role in increasing the incidence of sports injuries as the reduced flexibility and mobility associated with aging can make the body more prone to injury.

We completed a 40 patient open label, single arm, and multi-center clinical trial of VergenixSTR at hospitals in Israel which demonstrated the safety and evaluated the performance of VergenixSTR in patients suffering from tennis elbow or *lateral epicondylitis*. Tennis elbow is an inflammation of the tendons that join the forearm muscles on the outside of the elbow. The trial, which commenced in January 2015, initially enrolled 20 patients and was expanded to enroll an additional 20 patients. Patients enrolled in the trial received a one-time injection of VergenixSTR and monitored for the level of pain, tendon healing, and recovery of hand movement at three and six months after treatment.

In August 2016, we announced final results. At the three-month and six-month follow ups, patients treated with VergenixSTR reported an average 51% and 59% reduction in pain and improvement in motion, respectively, as measured by score improvement over the baseline on the Patient-Rated Tennis Elbow Evaluation, or PRTEE, questionnaire. The PRTEE questionnaire is designed to measure reduction in pain and recovery of motion for patients with tennis elbow. Furthermore, at three-month and six-month follow ups, 74% and 86%, respectively, of patients treated with VergenixSTR showed at least a 25% reduction in pain and improvement in motion as measured by PRTEE. In contrast, a study of standard-of-care tennis elbow therapies published in 2010 in the American Journal of Sports Medicine, or AJSM, reported that, at three and six months, 48% and 36%, respectively, of steroid patients showed at least a 25% reduction in pain and improvement in motion as measured by PRTEE. Also at the three-month and six-month follow ups, 62% and 64%, respectively, of patients treated with VergenixSTR showed at least a 50% reduction in pain and improvement in motion as measured by PRTEE, whereas the 2010 AJSM study showed 33% and 17% reductions at three and six months, respectively, for this same measurement.

In October 2016, we received CE marking certification for VergenixSTR. In November 2016, we entered into an exclusive distribution agreement with Arthrex GmbH, for VergenixSTR covering Europe, the Middle East, India, and certain African countries. Sales in Europe commenced in the fourth quarter of 2016.

In March 2018, Arthrex announced results of ACP Tendo, a product for treatment of tendinopathy combining our Vergenix®STR and Arthrex's platelet rich plasma extraction kit, in a European case series. The safety and performance of ACP Tendo was evaluated for the treatment of tendinopathy in 24 patients in 9 different European locations. The indications included injuries in rotator cuff, Achilles tendon, peroneal tendon, tibialis tendon and common extensor tendon. In all treatment groups, patient-recorded-pain decreased after 2 weeks and continued along this trend up to the last follow-up at 6 months. Specifically for rotator cuff and common extensor tendon groups, the functionality was increased over the study period, almost achieving pre-symptom levels after 6 months.

*VergenixFG—Wound Filler*

VergenixFG is an advanced wound care product based on our rhCollagen. In the European Union, VergenixFG is intended for the treatment of deep surgical incisions and deep wounds, including diabetic ulcers, venous and pressure ulcers, burns, bedsores, and other chronic wounds that are difficult to heal. VergenixFG is designed to be easy to use and to be administrated through a cannula by a doctor or nurse. The VergenixFG formulation provides a scaffold of pure human collagen, an important characteristic in promoting the closure of wounds, that fills the wound bed and is engineered to create maximal contact with the surrounding tissue, which is believed to enhance healing. VergenixFG provides complete coverage of the wound site, facilitates wound closure through an engineered synchronization between scaffold degradation and growth of new tissue, and offers a non-allergenic and pathogen-free scaffold for safe and efficacious wound care therapy. Other flowable gel products are available on the market, but they are based on tissue-derived collagen.

Our initial market for VergenixFG in Europe is chronic wounds, which includes diabetic foot ulcers, venous ulcers, and pressure ulcers.

The population prevalence of chronic wounds is 2.21/1000 people, which equates to 1 million out of the 447 million inhabitants of the EU 27 in 2021.

We have completed an open label, single arm, and multi-center registration trial of VergenixFG of 20 patients in Israel to demonstrate safety and to evaluate the performance of VergenixFG in patients with hard-to-heal chronic wounds of the lower limbs. Patients enrolled in the trial, received a single treatment of VergenixFG followed by a four-week follow up. Product performance was examined according to several measures, the main one being the percentage of wound closure achieved. The results were published in February 2019 in Wounds, a peer-reviewed journal focusing on wound care and wound research. The paper, titled, "A Novel Recombinant Human Collagen-based Flowable Matrix for Chronic Lower Limb Wound Management: First Results of a Clinical Trial," presents data from a previously reported independent study conducted by physicians at several wound care medical clinics and hospitals in Israel. Four weeks following treatment, nine wounds closed completely, fifteen wounds exhibited a greater than 70% closure, and the median wound area reduction was 94%. Only one patient failed to respond to treatment. All patients in the study reported a 50% reduction in pain. Further, no significant device-related adverse events were reported throughout the study.

In February 2016, we received CE marketing certification for VergenixFG. Since then we have entered into distribution agreements for the distribution of VergenixFG in several countries in Europe and Asia. We currently do not intend to pursue an FDA regulatory pathway to market for VergenixFG.

In an investigator initiated study, 24 adults with diabetes admitted to the inpatient clinic of the University Hospital in Pisa, Italy between March and July 2017 were randomized to receive VergenixFG plus standard treatment (12 patients) or standard treatment (12 patients). They were evaluated weekly for 6 months or until complete healing had occurred. The group that received VergenixFG had a significantly higher healing rate (83.3% versus 58.3%) and shorter healing time (64±4 days versus 90±11 days) than the group receiving standard treatment. It was concluded that the addition of VergenixFG to standard treatment increased healing rate and shortened healing time in patients with post-surgical diabetic foot wounds. The study was published by Lacopi E et al in The Diabetic Foot Journal, Vol 23 No 2 2020.

**Technology**

Our rhCollagen is based upon research conducted by our founder and Chief Scientist, Prof. Oded Shoseyov. We believe our technology is the only viable technology available for the production of recombinant type I human collagen, the most abundant collagen in the human body.

The production of our rhCollagen begins with the creation of genetically engineered cultures that are transferred to selected greenhouses across Israel and continues with the harvesting of tobacco leaves and the processing of such leaves to an extract which then undergoes purification until the completion of the rhCollagen.

Five human genes encoding heterotrimeric type I collagen are introduced into tobacco plants. The three protein chains that make up type I collagen—two α1 protein chains and one α2 protein chain—are encoded by two genes. The other three genes encode the human prolyl-4-hydroxylase (P4Hα and P4Hβ) as well as lysyl hydroxylase 3 (LH3) enzymes. These enzymes are responsible for key post-translational modifications of collagen, and plants co-expressing all five of these vacuole-targeted genes generate intact procollagen. The plants are grown in a greenhouse under strict growing protocols and mature leaves are transported to a protein extraction facility. Upon extraction, pro-collagen is enzymatically converted to atelocollagen using a plant-derived protease. The protein is purified to homogeneity through a cost-effective industrial process taking advantage of collagen's unique properties that make it soluble at a very low pH.

rhCollagen forms thermally stable triple helix structures which readily fibrillate at natural pH and low sodium chloride concentrations, making it ideal for use in the manufacture of products for tissue repair in the human body. Binding of integrins (transmembrane receptors) presented by the cells to a specific 3D structure on type I collagen fibrils requires a perfect triple helix. This binding is essential for binding and proliferation of cells on tissue repair scaffolds. In a study published in the *Journal of Biomedical Materials Research Part B: Applied Biomaterials*, rhCollagen was compared with acid-solubilized collagen from bovine dermis and pepsin-solubilized collagen from human fibroblast cell culture. Tested samples of the tissue-derived collagens had random fibrillar organization, whereas rhCollagen membranes showed far greater regional fibril alignment and transparency. RhCollagen membranes also showed better thermal stability compared with the tissue-derived collagens. The authors concluded that cross-linked rhCollagen membranes had a superior combination of desirable properties, namely higher transparency, higher thermal and tensile strengths, and adequate hydration.

We have selected tobacco as the medium for production of rhCollagen due to certain attributes of the tobacco plant that provide us with a number of advantages:

● The genetic structure of tobacco is well understood and therefore can be effectively manipulated.

● We can monitor the effect of weather conditions on the accumulation of proteins in the plants, which allows us to make optimal use of the growing area. We control the growing process in order to maximize yields.

● Because tobacco is not part of the food chain, there are no concerns about cross-contamination of the food supply that could result from genetically modified plants, which eases the regulatory burden.

● Tobacco plants may be grown in very large volumes and its growth time until reaching the desired maturity is relatively short (about eight weeks).

We have developed a large portfolio of configurations and composites based on our rhCollagen that are used to create high-quality products, including our three products, as follows:

**Our Development Activities**

***Development History***

Our rhCollagen was first developed as a collaboration among several commercial partners and the Hebrew University of Jerusalem, a major academic institution in Israel, under the direction of Professor Oded Shoseyov. Prof. Shoseyov is a faculty member at the Robert Smith Institute of Plant Science and Genetics at the Hebrew University of Jerusalem. The intellectual property was transferred to our wholly owned subsidiary, CollPlant Ltd.

As part of our regulatory strategy, we first developed and achieved a CE marking for a collagen-based non-invasive dressing, VergenixWD. We pursued a CE mark for this product as a predicate product for achieving in 2016 CE marking for our VergenixSTR and VergenixFG product in the European Union.

Between 2013 and 2017, we developed with Bioventus a surgical matrix, a novel resorbable carrier designed to help accelerate bone healing and formation. The surgical matrix is a novel resorbable carrier composed of rhCollagen and synthetic minerals which is intended to be charged with a bone morphogenetic protein for use as a bone graft substitute in bone repair indications such as spinal fusion and trauma. A study was led by Bioventus, and published in Science Translational Medicine, under the title "Bone Repair with a Receptor Optimized BMP-2/6/Activin Chimera Delivered in a Novel Ceramic/rhCollagen Matrix is Superior to BMP-2". The published article reports results from a study in non-human primates for bone regeneration using a receptor optimized chimera version of BMP-2/BMP-6/Activin A delivered in a composite matrix formulated with CollPlant's rhCollagen and ceramic granules. The rhCollagen matrix was specifically designed for high retention of the BMP chimera and has a unique design for cell infiltration and bone tissue growth. The treatment demonstrated tissue ingrowth that generated superior bone formation at concentrations of BMP that were 1/10<sup>th</sup> to 1/30<sup>th</sup> of the standard dosage of BMP-2 concentration approved by the FDA for clinical use in humans.

In May 2017, we created a division focused on development of collagen-based biological ink, or BioInk, following the expansion of our research activities in the field of 3D biologic printing of organs and tissues.

In May 2018, we filed a provisional patent application for photocurable dermal fillers comprising rhCollagen and hyaluronic acid, for the aesthetics market. This application represents an integral part of our strategy to expand the uses for rhCollagen into new, high value markets. The combination of hyaluronic acid, a naturally-occurring, moisture-binding compound, with our plant-based, tissue regenerating rhCollagen is intended to form the basis for a new dermal filler product line aimed at addressing the need for innovative aesthetic products to treat wrinkles.

In October 2018, we entered into a License, Development and Commercialization Agreement with LB, or the United License Agreement, pursuant to which we and LB collaborated in 3D bio-printing development of lungs and kidneys for transplant in humans. On February 24, 2021, we received a notice of termination from LB of the United License Agreement, and the termination went effective on March 26, 2021. Under the United License Agreement we received an upfront cash payment of $5 million in November 2018 and a further $3 million in September 2020 following the exercise of an option under the United License Agreement.

In August 2019, we announced that we are developing 3D bioprinted implants for regeneration of breast tissue and that we successfully produced first prototypes. The implants will be comprised of our rhCollagen and additional materials. Loaded with fat cells taken from the patient, these implants are intended to promote breast tissue regeneration. Eventually, the scaffold is designed to degrade and be replaced by newly grown natural breast tissue, that is free of any foreign material. We have since expanded our development to include injectable breast implants.

In January 2020, we announced that we became part of a new public-private ManufacturingUSA initiative, the ARMI. Headquartered in Manchester, New Hampshire, ARMI brings together a consortium of over 150 partner organizations from industry, government, academia and the non-profit sector to develop next-generation manufacturing processes and technologies for cells, tissues and organs. We intend to contribute our expertise to advance the entire science and industry of bioengineering and manufacturing.

In November 2020, we announced our development program of an antiviral agent for potential treatment of COVID-19 patients. In-vitro early results of our formulations showed significant inhibition of avian coronavirus infectivity. Our formulations designed for the potential treatment of COVID-19 patients are based on our proprietary recombinant rhCollagen imbedded with silver nanoparticles AgNP. The anti-viral treatment concept was evaluated in-vitro using an avian coronavirus, a model of the human coronavirus SARS-COV-2, grown on epithelial cells. The potential efficacy was assessed by the ability of the formulations to protect the epithelial cells from lethal doses of the virus. The results showed significant reduction in infectivity of the model virus by treatment with the rhCollagen-AgNP complexes. In December 2021, following a status assessment that we conducted, in which we took into account the success of COVID-19 vaccinations in reducing infection and mortality as a result of COVID-19, we decided to halt further antiviral agent product development at this stage and prioritize our current development plans in which we are currently engaged.

In December 2020, we entered into a product manufacturing and supply agreement with STEMCELL. As part of the agreement, we will sell our proprietary recombinant human Type I collagen (rhCollagen) to STEMCELL, which will incorporate our product into cell culture media kits. The agreement follows the companies' established business relationship, which started in 2014 when STEMCELL began purchasing and incorporating our rhCollagen into some of its cell culture expansion and differentiation media kits. To date, hundreds of companies, as well as research and academic institutes, have used these kits for research and development projects. STEMCELL will distribute the kits globally for use in the regenerative medicine research market.

In February 2021, we entered into a Development, Exclusivity and Option Products Agreement with AbbVie, pursuant to which we and AbbVie will collaborate in the development and commercialization of dermal and soft tissue filler products for the medical aesthetics market, using our rhCollagen technology and AbbVie's technology. To date, the development of the product continues to move forward according to plan.

In October 2021, we announced that our rhCollagen based Bioink was used successfully by researchers from Israel's Technion Institute of Technology to create a 3D bioprinted implantable tissue containing a network of blood vessels capable of supplying blood to the implanted tissue.

In February 2022, we signed a collaboration agreement with CELLINK, a BICO Group company. Under this agreement, CELLINK's bioprinter will be explored for the development of large-scale production of CollPlant's 3D bioprinted regenerative breast implants. This agreement will end in June 2023 and we are using printers of other companies for the development of our products.

In November 2022 we launched Collink.3D 90, an rhCollagen-based bioink solution for use in a variety of 3D bioprinting applications, offering increased mechanical properties to address additional printing requirements of soft and hard tissues. Collink.3D™ 90 is complementary to our first commercial bioink, Collink.3D 50, which was launched in November 2021, for use in 3D bioprinting. Collink.3D 50, our first commercially available rhCollagen-based bioink product is designed to allow the scalable and reproduceable biofabrication of scaffolds, tissues and organ transplants. Made entirely from human-derived collagen, Collink.3D bioinks enables the production of scaffolds that accurately mimic the physical properties of human tissues and organs, with improved bio-functionality, safety and reproducibility.

Also in November 2022, we entered into a license and research agreement with Tel Aviv University and Sheba Medical Center hospital, to co-develop a 'Gut-on-a-Chip' tissue model for drug discovery and high throughput screening of drugs. The model is intended to be used in personal medicine applications for the treatment of ulcerative colitis, an inflammatory bowel disease affecting millions of individuals worldwide.

In January 2023, we launched Collink.3D™ 50L in powder form, which is our first bioink available in powder form and provides enhanced operational flexibility to support a wide range of 3D bioprinting applications, including drug discovery, drug screening, tissue testing as well as the development of transplantable tissues and organs.

***Future Development***

To facilitate efficient development, our management holds regular research and development meetings where they prioritize development projects and determine future products. The prioritization process is based on several factors, including our business plan, commercial potential of the products, time to market, cost of development, feasibility of the project, and our established strategic objectives. We have several development projects that are in different stages of development.

We periodically examine the continued development of other collagen-based products that we have conceived. Each one of our current products offers a platform to product derivatives that can address other indications and contribute to our pipeline and revenues. Through ongoing research we are also pursuing other platforms for our rhCollagen, such as biomaterial coatings in order to reduce foreign body response and tissue adhesion.

 **Manufacturing, Supply, and Production**

The majority of our product research and development work is carried out at our offices and research laboratories center in Weizmann Science Park in Rehovot, Israel. The agricultural research and development and extraction activities for our rhCollagen are carried out at our site in Yessod Hama'ala, Israel.

We work with subcontractors with greenhouses for growing the tobacco plant containing human collagen. This tobacco growth occurs year-round and is optimized to the climate conditions in order to achieve the maximum amount of the protein in the leaves. Each grower has the infrastructure that can be scaled-up to accommodate future demand without additional capital expenditures.

We produce the rhCollagen from the tobacco plants at our manufacturing facility in Yessod Hama'ala and Rehovot, Israel. We believe that we currently have the ability to produce sufficient quantities of quality recombinant type I human collagen to support our product development activities and sales until 2026. Our activities are focused on yield improvement, scale-up, and cost reduction.

In late 2021, we initiated a plan to upgrade our production site in Israel into a large-scale integrated facility, in order to accommodate expected future increase in demand. We have also commenced activities to establish a US-based 3D bioprinting center of excellence.

While our upstream and downstream processes are quite robust and efficient, we continuously invest in further yield improvement and scalability, in order to reduce costs. In order to increase yield, we plan to increase biomass per growing area by using new genetic derivatives, improvement and optimization of growing techniques, and introduction of online controls. Our next-generation tobacco plants have been created through improved genetics and cross-breeding. In addition, increased growing areas will reduce overall cost per harvest.

We have an approved in-house purification capability. The purification facility includes clean rooms, logistics support areas, and dedicated production equipment to support the Company's production demand for the next few years. Under our current production techniques, we achieve a cost of goods that allow us to offer competitive pricing in the premium collagen-based products markets.

**Sales, Marketing, and Distribution**

We sell our BioInk and rhCollagen directly to our business partners, collaborators and selective customers. We anticipate that any products we develop in collaboration with a strategic partner or collaborator, such as dermal fillers which are based on our rhCollagen for the medical aesthetics, will be marketed by the partner's sales force, such as AbbVie.

We sell our rhCollagen in the research market mostly to selective customers, including business collaborators and potential collaborators.

We are marketing and distributing VergenixSTR and VergenixFG in the European market with business partners since 2016. We distribute VergenixFG in European and other countries with local distributors and distributed VergenixSTR with Arthrex GmbH mainly in Europe. We terminated the agreement with Arthrex effective as of December 31, 2020. We continue exploring opportunities to distribute our Vergenix products in additional countries.

In September 2020, we announced that we signed an agreement for distribution of VergenixFG with a Swiss-headquartered pharmaceutical group in six Commonwealth of Independent States (CIS) countries: Belarus, Kazakhstan, Georgia, Azerbaijan, Armenia and Uzbekistan. In July 2021, the agreement was extended to additional territories: Hong Kong, Denmark, Switzerland, Estonia, Latvia and Lithuania.

We have undertaken post marketing surveillance, or PMS, studies for both VergenixSTR and VergenixFG with our European key opinion leaders and physicians to generate additional clinical data that demonstrates the efficacy, safety and clinical benefit of our products. These PMS studies are intended to facilitate market adoption of our products in Europe, to confirm product safety and performance as well as to provide additional clinical evidence in support to regulatory filing and submission to other regulatory agencies in the future.

Our proprietary end products are marketed, and will be marketed, to physicians, hospitals, and clinics. We plan to expand the awareness of rhCollagen and our rhCollagen-based products to the end users through the publication of clinical trial data as well as marketing studies we may conduct, along with participation in academic and industry conferences. We will also market our rhCollagen to companies who are developing products using collagen and that do not compete with our primary end products. We anticipate entering into collaborations or partnerships with these companies where we would supply them with rhCollagen for use in their products in return for royalties.

**Competition**

We are not aware of any competitors that produce human collagen from plants or that produce recombinant type I human collagen. However, our industry is characterized by rapidly evolving technology and intense competition, and our rhCollagen-based products will compete with several alternatives, such as collagen that is produced from animals, human cadavers and synthetic products. Adequate protection of intellectual property, successful product development, adequate funding, and retention of skilled, experienced, and professional personnel are among the many factors critical to success in the pharmaceutical industry.

Generally, our competitors currently include large fully integrated companies, as well as academic research institutes and companies in various developmental stages that develop alternative sources and forms of collagen and tissue-derived products, who are using collagen that is extracted from animals and human cadavers.

The primary competitors to our BioInk are potential bio-material inks for 3D biological printing, based on tissue-derived collagens. Manufacturers of these products include, among others, BICO (formerly Cellink), Allevi (now part of 3D systems) and Humabiologics.

The main competitors to our 3D bioprinted regenerative breast implants that are in development include the commercially available breast implants by Allergan, Inc., an AbbVie company, and Mentor Worldwide LLC, Johnson & Johnson company.

The competitors to our photocurable dermal fillers that are in development include the main commercially available hyaluronic acid dermal filler brands by Galderma, Sinclair and Merz.

The competitors to our 3D bioprinted regenerative soft tissue matrix that is in development include the main commercially available acellular dermal matrices by AbbVie, MTF biologics, Bard and Stryker.

Our VergenixSTR product competes with companies that sell steroid injections and PRP kits, including, among others, Zimmer Biomet., Harvest Technologies Corporation, and Arteriocyte Medical Systems Inc.

The primary competitors to our VergenixFG product are products based on tissue-derived collagens. Manufacturers of these products include, among others, Integra Lifesciences Corporation, Organogenesis, Wright Medical Technology Inc., Smith & Nephew, Molnlycke, Convatec, Coloplast, and Urgo.

**Intellectual Property**

Our success depends, in part, on our ability to protect our proprietary technology and intellectual property. We rely on a combination of patent, trade secret, and trademark laws in the United States and other jurisdictions to protect our intellectual property rights. In addition, we rely on proprietary processes and know-how, intellectual property licenses, and other contractual rights, including confidentiality and invention assignment agreements, to protect our intellectual property rights and develop and maintain our competitive position.

***Patents***

As of March 15, 2023, we have a global patent portfolio that is comprised of twelve patent families. More than three dozen of our patent applications have issued as patents or will issue soon, having been allowed by the relevant patent office. We have exclusive ownership of 21 issued patents in our patent family that cover methods of creating collagen-producing plants and three issued patents that cover methods of processing recombinant collagen. These issued patents and others that may issue in the future in these patent families, assuming timely payment of annual fees, are expected to expire in 2025-2028. We have ongoing patent application covering the specific collagen producing plants based on their genetic arrangement. If granted, it could provide patent protection for the collagen producing plants until 2039. Our patent portfolio also includes patent families that cover different uses of collagen including 3D Bioprinting, dermal fillers and soft tissue fillers which, if granted, could provide patent protection for particular formulations and uses of our rhCollagen until 2038-2040.

In addition, our patent portfolio includes pending applications, some of which are jointly owned with Yissum Research Development Company of the Hebrew University of Jerusalem Ltd., or Yissum.

We are not aware of any impediments to the patent applications being granted in the United States or other jurisdictions. However, some of our patent applications may never issue as patents, and our issued patents and any that may issue in the future may be challenged, invalidated or circumvented.

 ****

***Trade Secrets and Confidential Information***

In addition to patented technology, we rely on our trade secrets and continuing technological innovations to develop and maintain our competitive position. In an effort to protect our trade secrets, we rely on, among other safeguards, confidentiality and invention assignment agreements to protect our proprietary technology, 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, consultants and advisors to execute confidentiality agreements in connection with their employment or consulting relationships with us and to disclose and assign to us inventions conceived in connection with their services to us. These agreements also provide that all confidential information developed or made known to the individual during the course of their relationship with us must be kept confidential, except in specified circumstances.

***Materials Transfer Agreements***

We periodically enter into materials transfer agreements with commercial organizations, medical institutions and research and development institutions to transfer materials and products developed by us. These agreements include provisions that are customary for such agreements concerning the permitted use of the transferred material and any results obtained using the material, confidentiality, the rights in the transferred materials and in the results of the research and/or development in which the materials are used, and the instructions concerning care and usage of the materials. These agreements may be used as a basis for further cooperation between us and the counterparties.

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.D. Risk Factors."

***Agreement with Yissum Research Development Company of the Hebrew University of Jerusalem Ltd. with respect to our rhCollagen***

**Government Regulation**

We are a developer of products which are subject to extensive regulation in the United States, the European Union and other jurisdictions. These regulations govern, among other things, the introduction of new products, the observance of certain standards with respect to the design, manufacture, testing, promotion and sales of the products, the maintenance of certain records, the ability to track devices, the reporting of potential product defects, the import and export of devices, and other matters.

In order to obtain marketing authorization in the United States, we and/or our partners would be subject to extensive regulation by the FDA and other federal, state, and local regulatory agencies. The Federal Food, Drug, and Cosmetic Act, or FD&C Act, the Public Health Service Act, or the PHS Act, and their implementing regulations set forth, among others, requirements for the research, testing, development, manufacture, quality control, safety, effectiveness, approval, labelling, storage, record keeping, reporting, distribution, import, export, advertising, and promotion of our products. A failure to comply with relevant requirements may lead to administrative, civil, or criminal sanctions. These sanctions could include the imposition by the FDA of a clinical hold or other suspension on clinical trials, refusal to approve pending marketing applications or supplements, withdrawal of approval, warning letters, product recalls, product seizures, total or partial suspension of production or distribution, injunctions, fines, civil penalties, or criminal prosecution.

Although the discussion below focuses on regulation in the United States, we and/or our partners anticipate seeking approval for the marketing of products in other countries which have their own regulatory requirements. Generally, our activities or those of our partners in other countries will be subject to regulations that are similar in nature and scope as that imposed in the United States such as medical device approval, quality system requirements, product data and certifications, although there can be important differences and the number and scope of these regulatory requirements are generally increasing.

We and/or our partners must obtain approval by comparable regulatory authorities of foreign countries outside of the European Union and the United States before we can commence clinical trials or marketing of our products in those countries. The approval process varies from country to country and the process may be longer or shorter than that required for FDA approval. In addition, the requirements governing the conduct of clinical trials, product licensing, pricing, and reimbursement vary greatly from country to country. In all cases, clinical trials must be conducted in accordance with the FDA's regulations, commonly referred to as good clinical practices, or GCPs, and the applicable regulatory requirements and ethical principles that have their origin in the Declaration of Helsinki.

Government regulation may delay or prevent testing or marketing of our products and impose costly procedures upon our activities. The testing and approval process, and the subsequent compliance with appropriate statutes and regulations, require substantial time, effort, and financial resources, and we cannot be certain that the FDA or any other regulatory agency will grant approvals for our products or any future product candidates on a timely basis or at all. The policies of the FDA or any other regulatory agency may change and additional governmental regulations may be enacted that could prevent or delay regulatory approval of our products or any future product candidates or approval of new indications or label changes. We cannot predict the likelihood, nature or extent of adverse governmental regulation that might arise from future legislative, judicial, or administrative action, either in the United States or abroad.

**Approval by Health Authorities**

The following is a summary review of the laws and regulations governing our operations or those of our partners. Our end products are medical and aesthetics products, and their marketing, once development is complete, is contingent upon approval of the health authorities in every country in which the products will be marketed:

***Israel***

Our operations are subject to permits from the Ministry of Health on two levels:

● First, the registration of medical devices, importing and marketing the medical devices and accessories, and issuing the documentation necessary for the export of medical devices from Israel are all supervised by the medical accessories and devices unit, or AMAR, of the Ministry of Health.

● Second, pertaining to research and development, clinical trials in humans are subject to the approval of the Helsinki Committee (an ethics committee) of the institution conducting the trial, which is governed by the Public Health Regulations (Trials in Human Beings), 1980, including all amendments until 1999, or the Trials in Human Subjects Regulations and are conducted in accordance with the Guidelines for Clinical Trials in Human Subjects issued by the Ministry of Health, or the Guidelines, and the guidelines of the Declaration of Helsinki, or any other approval required by the Ministry of Health. According to the Trials in Human Subjects Regulations and the Guidelines, the Helsinki Committee must plan and approve every experimental process that involves human beings. The institutional Helsinki Committee acts in the medical institution where the trial is performed and is the body that approves and supervises the entire trial process. In practice, the physician, who is the principal investigator, submits a trial protocol to the committee on behalf of the requesting party. The committee forwards its decisions regarding the requests for clinical trials that were approved by the committee to the manager of the medical institute and the manager has the authority to approve the requests, and in some cases the additional approval of the Ministry of Health will be required. According to the procedure for medical trials in human beings set forth by the Ministry of Health, the Helsinki Committee will not approve performance of a clinical trial, unless it is absolutely convinced that the following conditions, among others, are fulfilled: (i) the anticipated benefits for the participant in the clinical trial and to the requesting party to justify the risk and the inconvenience involved in the clinical trial to its participant; (ii) the available medical and scientific information justifies the performance of the requested clinical trial; (iii) the clinical trial is planned in a scientific manner that enables a solution to the tested question and is described in a clear, detailed, and precise manner in the protocol of the clinical trial, conforming with the Declaration of Helsinki; (iv) the risk to the participant in the clinical trial is as minimal as possible; (v) optimal monitoring and follow-up of the participant in the clinical trial; (vi) the initiator, the principal investigator and the medical institute are capable and undertake to allocate the resources required for adequate execution of the clinical trial, including qualified personnel and required equipment; and (vii) the nature of the commercial agreement with the principal investigator and the medical institute does not impair the adequate performance of the clinical trial.

All phases of clinical trials conducted in Israel must be conducted in accordance with the Trials in Human Subjects Regulations, including amendments and addenda thereto, the Guidelines, and the International Conference for Harmonized Tripartite Guideline for Good Clinical Practice. The Trials in Human Subjects Regulations and the Guidelines stipulate that a medical study on humans will only be approved after the Helsinki Committee at the hospital intending to perform the study has approved the medical study and notified the relevant hospital director in writing. In addition, certain clinical studies require the approval of the Ministry of Health. The relevant hospital director, and the Ministry of Health, if applicable, also must be satisfied that the study is not contrary to the Declaration of Helsinki or to other regulations.

In June 2017, we received AMR approval for VergenixFG and started treating patients in Israel. In March 2018, we received AMR approval for VergenixSTR.

***United States***

The regulatory process of obtaining product approvals and clearances can be onerous and costly. Foreign companies manufacturing medical devices intended for sale in the United States are required to meet the FDA's regulatory requirements. The FDA does not recognize the regulatory certification provided by governmental authorities of other countries.

<u>Regulation of Combination Products</u>

The FDA has specified a definition for the term "combination product," which includes: (1) a product comprised of two or more regulated components, e.g., drug/device, biologic/device, drug/biologic, or drug/device/biologic, which are physically, chemically, or otherwise combined or mixed and produced as a single entity; (2) two or more separate products packaged together in a single package or as a unit and comprised of drug and device products, device and biological products, or biological and drug products; (3) a drug, device, or biological product packaged separately that according to its investigational plan or proposed labeling is intended for use only with an approved individually specified drug, device, or biological product where both are required to achieve the intended use, indication, or effect and where, upon approval of the proposed product, the labeling of the approved product would need to be changed, e.g., to reflect a change in intended use, dosage form, strength, route of administration, or significant change in dose; or (4) any investigational drug, device, or biological product packaged separately that according to its proposed labeling is for use only with another individually specified investigational drug, device, or biological product where both are required to achieve the intended use, indication, or effect.

The FDA is divided into various "Centers" by product type such as the Center for Drug Evaluation and Research, or CDER, the Center for Biologics, Evaluation and Research, or CBER, or the Center for Devices and Radiological Health, or CDRH. Different Centers review drug, biologic, or device applications.

The FDA is charged with assigning a Center with primary jurisdiction, or a lead Center, for review of a combination product. That determination is based on the "primary mode of action," or PMOA, of the combination product. Thus, if the PMOA of a device-biologic combination product is attributable to the biologic product, CBER, which is responsible for premarket review of the biologic product, would have primary jurisdiction for the combination product.

The FDA has also established an Office of Combination Products to address issues surrounding combination products and provide more certainty to the regulatory review process. That office serves as a focal point for combination product issues for agency reviewers and industry. It is also responsible for developing guidance and regulations to clarify the regulation of combination products and for assignment of the FDA center that has primary jurisdiction for review of combination products where the jurisdiction is unclear or in dispute.

After formally establishing the PMOA through an applicant's Request for Designation, the Center that regulates that portion of the product that generates the PMOA becomes the lead evaluator. When evaluating an application, a lead Center may consult other centers but still retain complete reviewing authority, or it may collaborate with another Center, wherein the lead Center assigns concurrent review of a specific section of the application to another Center, delegating its review authority for that section.

Typically, the FDA requires a single marketing application submitted to the Center selected to be the lead evaluator, although the agency has the discretion to require separate applications to more than one Center. One reason to submit multiple evaluations is if the applicant wishes to receive some benefit that accrues only from approval under a particular type of application, like new drug product or orphan drug exclusivity. If multiple applications are submitted, each may be evaluated by a different lead Center. When submitting multiple applications, the applicant may be subject to the payment of two user fees, but a waiver of such fees may be obtained under certain limited circumstances.

The FDA may subject a combination product to two or more sets of legal authorities, e.g., drug/device, biologic/device, or drug/biologic drug, but it has the authority to deem one set of legal authorities sufficient. FDA's standard of review for a combination products application and the applicable legal authority or authorities will depend on a case-by-case basis evaluation of the scientific and technical issues and risk profile relevant to a combination product and its constituent parts. Because of the breadth and complexity of this analysis in each case, no single regulatory paradigm is appropriate for all combination products.

After receiving FDA approval or clearance, an approved or cleared product must comply with post-marketing safety reporting requirements applicable to the product based on the application type under which it received marketing authorization. In the case of current good manufacturing practices, or cGMP, the applicant may take one of two approaches: (1) complying with cGMP for each constituent part, or (2) a streamlined approach specific to combination products, subject to certain limitations.

In January 2019, the FDA responded to the Company's Pre-RFD regarding product classification and jurisdictional assessment. The FDA's OCP determined that VergenixSTR should be classified as a Combination Product, specifically a drug/biologic/device product, and should be assigned to the FDA's CBER. A Pre-RFD is FDA's preliminary, nonbinding assessment of (1) the regulatory identity or classification of a product as a drug, device, biological product, or combination product, and (2) which FDA Center (i.e., CBER, CDER, or CDRH) will have primary jurisdiction for the premarket review and regulation of the product. Therefore, this classification and jurisdictional assessment is subject to change. We currently do not intend to pursue a FDA regulatory pathway to market for VergenixSTR and VergenixFG. We nevertheless include a discussion of FDA's requirements for approval of, and ongoing, regulation for drugs, biologics, and medical devices below which are relevant to the end products that we are either developing internally or in collaboration with our partners.

***Marketing Authorization for Drugs and Biologics in the U.S.***

A new biologic must be approved by the FDA through the biologics license application, or BLA, process before it may be legally marketed in the U.S. A new drug must be approved by the FDA through the new drug application, or NDA, process before it may be legally marketed in the U.S.

The animal and other non-clinical data and the results of human clinical trials performed under an Investigational New Drug, or IND, application and under similar foreign applications will become part of the BLA or NDA.

In the U.S., the FDA regulates biologics under the Public Health Service Act, or PHS Act, and implementing regulations, and under the Federal Food, Drug, and Cosmetic Act, or FDCA, and implementing regulations, respectively. The U.S. regulates drugs under the FDCA. The process of obtaining regulatory approvals and the subsequent compliance with applicable federal, state, local, and foreign statutes and regulations require the expenditure of substantial time and financial resources. Failure to comply with the applicable U.S. requirements at any time during the product development process, approval process or after approval may subject an applicant to administrative or judicial sanctions. These sanctions could include the FDA's refusal to approve pending applications, withdrawal of an approval, a clinical hold, warning letters, requesting product recalls, product seizures, total or partial suspension of production or distribution, injunctions, fines, refusals of government contracts, restitution, disgorgement, or civil or criminal penalties. Any agency or judicial enforcement action could have a material adverse effect on us. The process required by the FDA before a drug or biologic may be marketed in the U.S. generally involves the following:

● completion of preclinical laboratory tests, animal studies and formulation studies according to Good Laboratory Practices, or GLP, or other applicable regulations;

● submission to the FDA of an IND which must become effective before human clinical trials may begin;

● approval by an IRB representing each clinical trial site before each clinical trial may be initiated;

● performance of adequate and well-controlled human clinical trials according to Good Clinical Practices, or GCP, to establish the safety and efficacy of the proposed biologic for its intended use;

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

● satisfactory completion of an FDA inspection of the manufacturing facility or facilities at which the drug is produced to assess compliance with current good manufacturing practice, or cGMP, to assure that the facilities, methods and controls are adequate to preserve the drug's identity, strength, quality and purity; and satisfactory completion of any FDA audits of the clinical study sites to assure compliance with GCP, and the integrity of clinical data in support of the BLA or NDA; and

● FDA review (which may include Advisory Panel review and approval) and approval of the BLA or NDA.

Once a biologic or drug product candidate is identified for development, it enters the preclinical testing stage. Preclinical tests include laboratory evaluations of product chemistry, toxicity and formulation, as well as animal studies. An IND sponsor must submit the results of the preclinical tests, together with manufacturing information and analytical data, to the FDA as part of the IND. The sponsor will also include a protocol detailing, among other things, the objectives of the first phase of the clinical trials, the parameters to be used in monitoring safety, and the effectiveness criteria to be evaluated if the first phase lends itself to an efficacy evaluation. Some preclinical testing may continue even 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, places the clinical trial on a clinical hold. In such a case, the IND sponsor and the FDA must resolve any outstanding concerns before the clinical trial can begin. Clinical holds also may be imposed by the FDA at any time before or during studies due to safety concerns or non-compliance.

All clinical trials must be conducted under the supervision of one or more qualified investigators in accordance with GCP regulations. They must be conducted under protocols detailing the objectives of the trial, dosing procedures, subject selection and exclusion criteria, and the safety and effectiveness criteria to be evaluated. Each protocol must be submitted to the FDA as part of the IND, and progress reports detailing the results of the clinical trials must be submitted at least annually. In addition, timely safety reports must be submitted to the FDA and the investigators for serious and unexpected adverse events. An IRB responsible for the research conducted at each institution participating in the clinical trial must review and approve each protocol before a clinical trial commences at that institution and must also approve the information regarding the trial and the consent form that must be provided to each trial subject or his or her legal representative, monitor the study until completed and otherwise comply with IRB regulations.

● *Phase I*: The product candidate is initially introduced into healthy human subjects and tested for safety, dosage tolerance, absorption, metabolism, distribution and excretion. In the case of some products for severe or life-threatening diseases, such as cancer, especially when the product may be too inherently toxic to ethically administer to healthy volunteers, the initial human testing may be conducted in patients.

● *Phase II*: This phase involves studies in a limited patient population to identify possible adverse effects and safety risks, to preliminarily evaluate the efficacy of the product for specific targeted diseases and to determine dosage tolerance and optimal dosage.

● *Phase III*: Clinical trials are undertaken to further evaluate dosage, clinical efficacy and safety in an expanded patient population at geographically dispersed clinical study sites. These studies are intended to establish the overall risk-benefit ratio of the product candidate and provide, if appropriate, an adequate basis for product labeling.

Concurrent with clinical trials, companies usually complete additional animal studies and must also develop additional information about the chemistry and physical characteristics of a biologic or drug and finalize a process for manufacturing the product in commercial and clinical quantities in accordance with cGMP requirements. The manufacturing process must be capable of consistently producing quality batches of the product candidate, and, among other things, the manufacturer must develop methods for testing the identity, strength, quality and purity of the final 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. Before approving a BLA or NDA, 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 full compliance with cGMP requirements and adequate to assure consistent production of the product within required specifications. The PHS Act in particular emphasizes the importance of manufacturing control for products like biologics whose attributes cannot be precisely defined.

Manufacturers and others involved in the manufacture and distribution of products must also register their establishments with the FDA and certain state agencies. Both domestic and foreign manufacturing establishments must register and provide additional information to the FDA upon their initial participation in the manufacturing process. Any product manufactured by or imported from a facility that has not registered, whether foreign or domestic, is deemed misbranded under the FDCA.

Establishments may be subject to periodic unannounced inspections by government authorities to ensure compliance with cGMP and other laws. Manufacturers may have to provide, on request, electronic or physical records regarding their establishments. Delaying, denying, limiting, or refusing inspection by the FDA may lead to a product being deemed to be adulterated. Human clinical trials for biologics and drugs are typically conducted in three sequential phases that may overlap or be combined. If there are two independent modes of action, neither of which is subordinate to the other, the FDA makes a determination as to which center to assign the product based on consistency with other combination products raising similar types of safety and effectiveness questions or to the center with the most expertise in evaluating the most significant safety and effectiveness questions raised by the combination product.

***<u>Marketing Authorization for Medical Devices in the U.S.</u>***

In the United States, medical devices are regulated by the FDA as required under the FDCA. Unless an exemption applies or the product is a Class I device, a new medical device will require either a 510(k) clearance or approval of a Premarket Approval, or PMA, before it can be marketed in the United States. The information that must be submitted to the FDA in order to obtain clearance or approval to market a new medical device varies depending on how the medical device is classified by the FDA. Medical devices are classified into one of three classes on the basis of the controls deemed by the FDA to be necessary to reasonably ensure their safety and effectiveness. Class I devices, which are those that have the lowest level or risk associated with them, are subject to general controls, including labeling, premarket notification, and adherence to the QSR. Class II devices are subject to general controls and special controls, including performance standards. Class III devices, which have the highest level of risk associated with them, are subject to most of the previously identified requirements as well as to premarket approval. Most Class I devices and some Class II devices are exempt from the 510(k) requirement, although manufacturers of these devices are still subject to registration, listing, labeling and Quality System Requirements, or QSR.

A 510(k) premarket notification must demonstrate that the device in question is substantially equivalent to another legally marketed device, or predicate device, that likely did not require premarket approval. In evaluating the 510(k), the FDA will determine whether the device has the same intended use as the predicate device, and: (i)(a) has the same technological characteristics as the predicate device, or (b) has different technological characteristics; and (ii)(a) the data supporting the substantial equivalence contains information, including appropriate clinical or scientific data, if deemed necessary by the FDA, that demonstrates that the device is as safe and as effective as a legally marketed device, and (b) does not raise different questions of safety and effectiveness than the predicate device. Most 510(k)s do not require clinical data for clearance, but the FDA may request such data. If the FDA does not agree that the new device is substantially equivalent to the predicate device, the new device will be classified in Class III, and the manufacturer must submit a PMA.

The PMA process is more complex, costly, and time consuming than the 510(k) clearance procedure. A PMA must be supported by extensive data including, but not limited to, technical, preclinical, clinical, manufacturing, control, and labeling information to demonstrate to the FDA's satisfaction the safety and effectiveness of the device for its intended use. After a PMA is submitted, the FDA has 45 days to determine whether it is sufficiently complete to permit a substantive review, but this timeline may be delayed. If the PMA is complete, the FDA will file the PMA. The FDA is subject to performance goal review times for PMAs and may issue a decision letter as a first action on a PMA within 180 days of filing, but if it has questions, it will likely issue a first major deficiency letter within 150 days of filing. It may also refer the PMA to an FDA advisory panel for additional review and will conduct a preapproval inspection of the manufacturing facility to ensure compliance with the QSR, either of which could extend the 180-day response target. A PMA can take several years to complete, and there is no assurance that any submitted PMA will ever be approved. Even when approved, the FDA may limit the indication for which the medical device may be marketed. Changes to the device, including changes to its manufacturing process, may require the approval of a supplemental PMA.

If a medical device is determined to present a "significant risk," the manufacturer may not begin a clinical trial until it submits an investigational device exemption, or IDE, to the FDA and obtains approval of the IDE from the FDA. The IDE must be supported by appropriate data, such as animal and laboratory testing results, and include a proposed clinical protocol. The clinical trials must be conducted in accordance with applicable regulations, including but not limited to the FDA's IDE regulations and current good clinical practices. A clinical trial may be suspended by the FDA or the sponsor at any time for various reasons, including a belief that the risks to the study participants outweigh the benefits of participation in the trial. Even if a clinical trial is completed, the results may not demonstrate the safety and efficacy of a device or may be equivocal or otherwise not be sufficient to obtain approval. Medical devices, however, typically rely on one or a few pivotal studies rather than Phase I, II and III clinical trials

Clinical trials are subject to extensive monitoring, recordkeeping and reporting requirements. Clinical trials must be conducted under the oversight of an IRB for the relevant clinical trial sites and must comply with FDA regulations, including, but not limited to, those relating to good clinical practices. To conduct a clinical trial, we also are required to obtain the patient's informed consent in a form and substance that complies with both FDA requirements and state and federal privacy and human subject protection regulations.

The FDA, the IRB, or we could suspend a clinical trial at any time for various reasons, including a belief that the risks to study subjects outweigh the anticipated benefits or a finding that the research subjects or patients are being exposed to an unacceptable health risk. Similarly, an IRB can suspend or terminate approval of a clinical trial at its institution if the clinical trial is not being conducted in accordance with the IRB's requirements or if the drug has been associated with unexpected serious harm to patients. Clinical testing may not be completed successfully within any specified period, if at all. Even if a trial is completed, the results of clinical testing may not adequately demonstrate the safety and efficacy of the device or may otherwise not be sufficient to obtain FDA clearance or approval to market the product in the United States. Similarly, in Europe, the clinical study must be approved by a local ethics committee and in some cases, including studies with high-risk devices, by the ministry of health in the applicable country.

In August 2010, we submitted a 510(k) notification to the FDA for VergenixWD, a collagen-based non-invasive dressing. In October 2010, we received notice that the Center for Devices and Radiological Health, or CDRH, which is the FDA center with jurisdiction over medical devices, determined that the product required a submission of a PMA for regulatory approval and not a 510(k). We filed an appeal of this decision that was denied, and in April 2012, the FDA confirmed its previous determination that our product would require PMA approval prior to its marketing in the United States. We believe that most, if not all, of our products will be subject to the PMA process or will be considered combination products subject to at least some medical device regulations.

We expect, based on our prior limited interaction with the FDA in connection with our predecessor wound healing product, that our current products and pipeline products, including dermal fillers and breast implants, will be regulated as medical devices through a PMA process; however, no assurance can be given that the FDA will not impose additional, more stringent, regulatory requirements with respect to one or more of our current or future product candidates. Conducting clinical trials for our pipeline product candidates that are required to undergo the PMA process may take one to three years, depending on the composition of the product candidate under development and its designation.

We are not presently conducting any discussions with the FDA with respect to any of our products.

***Post-Approval Regulation of Biologics, Drugs and Medical Devices***

After a product is placed on the market, numerous regulatory requirements continue to apply. In addition to the requirements below, adverse event reporting regulations require that we report to the FDA any incident in which our product may have caused or contributed to a death or serious injury or in which our product malfunctioned and, if the malfunction were to recur, would likely cause or contribute to death or serious injury. Additional regulatory requirements include:

● product listing and establishment registration, which helps facilitate FDA inspections and other regulatory action;

● cGMP or QSR, which requires manufacturers, including third-party manufacturers, to follow stringent design, validation, testing, control, documentation and other quality assurance procedures during all aspects of the design and manufacturing process;

● labeling regulations and FDA prohibitions against the promotion of products for uncleared, unapproved or off-label use or indication;

● clearance of product modifications that could significantly affect safety or effectiveness or that would constitute a major change in intended use of one of our approved medical products;

● notice or approval of product or manufacturing process modifications or deviations that affect the safety or effectiveness of one of our approved medical products;

● post-approval restrictions or conditions, including post-approval study commitments;

● post-market surveillance regulations, which apply, when necessary, to protect the public health or to provide additional safety and effectiveness data for the medical product;

● the FDA's recall authority, whereby it can ask or, under certain conditions, order device manufacturers to recall from the market a product that is in violation of governing laws and regulations;

● regulations pertaining to voluntary recalls; and

● notices of corrections or removals.

Also, quality control and manufacturing procedures must continue to conform to current Good Manufacturing Practices, or cGMP after approval, which includes, among other things, maintenance of a stability program. The FDA periodically inspects manufacturing facilities to assess compliance with cGMP, which imposes extensive procedural, substantive, and record keeping requirements. In addition, changes to the manufacturing process are strictly regulated and, depending on the significance of the change, may require prior FDA approval before being implemented. FDA regulations also require investigation and correction of product out of specification results and impose reporting and documentation requirements upon us and any third-party manufacturers that we may decide to use. Accordingly, manufacturers must continue to expend time, money and effort in the area of production and quality control to maintain compliance with cGMP and other aspects of regulatory compliance. The holder of an NDA is responsible for legal and regulatory compliance for advertising and promotion of the drug product. We are required to provide to the FDA copies of all drug promotion at the time of first use and to ensure that all information disseminated conforms to the product's approved labeling and other FDA regulations and policies.

A biologic product may also be subject to official lot release, meaning that the manufacturer is required to perform certain tests on each lot of the product before it is released for distribution. If the product is subject to official lot release, the manufacturer must submit samples of each lot, together with a release protocol showing a summary of the history of manufacture of the lot and the results of all of the manufacturer's tests performed on the lot, to the FDA. The FDA may, in addition, perform certain confirmatory tests on lots of some products before releasing the lots for distribution. Finally, the FDA will conduct laboratory research related to the safety, purity, potency and effectiveness of pharmaceutical products.

Advertising and promotion of medical devices, in addition to being regulated by the FDA, are also regulated by the U.S. Federal Trade Commission, or FTC, and by state regulatory and enforcement authorities. Promotional activities for FDA-regulated products of other companies have been the subject of enforcement action brought under healthcare reimbursement laws and consumer protection statutes. Furthermore, under the federal U.S. Lanham Act and similar state laws, competitors and others can initiate litigation relating to advertising claims. In addition, we are required to meet regulatory requirements in countries outside the United States, which can change rapidly with relatively short notice. If the FDA determines that our promotional materials or training constitutes promotion of an unapproved or uncleared use, it could request that we modify our training or promotional materials or subject us to regulatory or enforcement actions. It is also possible that other federal, state or foreign enforcement authorities might take action if they consider our promotional or training materials to constitute promotion of an unapproved use, which could result in significant fines or penalties under other statutory authorities, such as laws prohibiting false claims for reimbursement.

Failure by us or by our third-party manufacturers and suppliers to comply with applicable regulatory requirements can result in enforcement action by the FDA or other regulatory authorities, which may result in sanctions including, but not limited to:

● untitled letters, warning letters, fines, injunctions, consent decrees and civil penalties;

● customer notifications or repair, replacement, refunds, recall, detention or seizure of our products;

● operating restrictions or partial suspension or total shutdown of production;

● refusing or delaying requests for 510(k) clearance or PMA approvals of new products or modified products;

● withdrawing 510(k) clearances or PMA approvals that have already been granted;

● refusing to grant export approval for our products; or

● criminal prosecution.

***Proteins Intended for Therapeutic Use***

In the United States, proteins intended for therapeutic use, whether derived from plants, animals, microorganisms, or recombinant versions of these products, are regulated as biological products that have been transferred from the FDA Center for Biologics Evaluation and Research, or CBER, to the Center for Drug Evaluation and Research, or CDER. CDER has regulatory responsibility, including premarket review and continuing oversight over the transferred products. Cellular products, including products composed of human, bacterial, or animal cells, or from physical parts of those cells, remain under the jurisdiction of CDER.

Our products are based on our recombinant type I human collagen, or rhCollagen, a form of human collagen produced with our proprietary plant based genetic engineering technology. Therefore, we believe our underlying platform technology would be regulated as a biologic by CDER in the U.S.

***Regenerative Medicine Advanced Therapy Designation***

Under section 3033 of the 21st Cures Act, or Cures Act, a drug is eligible for regenerative medicine advanced therapy (RMAT) designation if (1) the drug is a regenerative medicine therapy, which is defined as a cell therapy, therapeutic tissue engineering product, human cell and tissue product, or any Combination Product using such therapies or products, except for those regulated solely under section 361 of the PHS Act and 21 C.F.R. Part 1271, (2) the drug is intended to treat, modify, reverse, or cure a serious or life-threatening disease or condition, and (3) preliminary clinical evidence indicates that the drug has the potential to address unmet medical needs for such disease or condition. If we pursue U.S. marketing approval for any of our products, we may be able to avail ourselves of this pathway or another expedited pathway.

***Human Cells, Tissues, and Cellular and Tissue-Based Products Regulation***

Under Section 361 of the PHS Act, the FDA issued specific regulations governing the use of human cells, tissues, and cellular and tissue-based products, or HCT/Ps, in humans. Pursuant to Part 1271 of Title 21 of the Code of Federal Regulations, or Part 1271, the FDA established a unified registration and listing system for establishments that manufacture and process HCT/Ps. The regulations also include provisions pertaining to donor eligibility determinations; current good tissue practices covering all stages of production, including harvesting, processing, manufacture, storage, labeling, packaging, and distribution; and other procedures to prevent the introduction, transmission, and spread of communicable diseases.

The HCT/P regulations strictly constrain the types of products that may be regulated solely under these regulations. Factors considered include the degree of manipulation, whether the product is intended for a homologous function, whether the product has been combined with noncellular or non-tissue components, and the product's effect or dependence on the body's metabolic function. In those instances where cells, tissues, and cellular and tissue-based products have been only minimally manipulated, are intended strictly for homologous use, have not been combined with noncellular or nontissue substances, and do not depend on or have any effect on the body's metabolism, the manufacturer is only required to register with the FDA, submit a list of manufactured products, and adopt and implement procedures for the control of communicable diseases. If one or more of the above factors has been exceeded, the product would be regulated as a drug, biological product, or medical device rather than an HCT/P.

We do not believe that Part 1271 requirements currently apply to us because we are not currently investigating, marketing or selling cellular therapy products in the U.S. If we were to change our business operations in the future, the FDA requirements that apply to us may also change, and we would potentially need to expend significant resources to comply with these requirements.

***European Union***

<u>Legal Requirements for Medical Devices in the EU</u>

EU law on medical devices is governed by Regulation EU 2017/745, or the EU MDR, which repealed and replaced Council Directive 93/42/EEC, or MDD, and Regulation 2017/746 on in vitro diagnostic medical devices. The EU MDR became fully applicable on May 26, 2021. However, medical devices that have been CE-certified under the MDD can be marketed with these CE-certificates until they expire or until May 26, 2024 (whichever is earlier), which on January 6, 2023, was proposed to be extended by the European Commission to December 31, 2027 for Class III devices and Class IIB implantable devices, which are the categories our products are classified under.

Under the Medical Device Regulation or EU MDR, medical devices must meet the EU MDR, requirements and have a CE mark prior to marketing in the European Union, or EU. CE marking is the uniform labeling system of products designed to facilitate the supervision and control of the EU concerning manufacturers' compliance with the various regulations and directives of the EU and to clarify the obligations imposed in the various legislative provisions in the EU. Use of a uniform product labeling indicates compliance with all of the directives and regulations required for the application of such labeling, and it is effective as a manufacturer's declaration that the product meets the required criteria and technical specifications of the relevant authorities such as health, safety, and environmental protection. CE marking ensures free trade between the EU and European Economic Area (or EEA) countries (Iceland, Liechtenstein, and Norway) and other countries that have mutual recognition agreements with regard to medical devices with the EU, in particular Turkey, and permits the enforcement and customs authorities in European countries not to allow the marketing of similar products that do not bear the CE mark. With regard to Switzerland, the respective mutual recognition agreement was not renewed in time to implement the MDR and as a result, Switzerland currently has the status of a third country with regard to EU medical devices law. As a result, EU law compliant medical devices are not freely traded with Switzerland but instead, additional requirements have to be met for CE-marked medical devices to be shipped to Switzerland, and *vice versa*.

CE-marking requires the performance of a conformity assessment procedure to establish that a product meets the essential requirements under the EU MDR. The nature of the conformity assessment procedure and the data required under it - including the question of whether or not a clinical investigation of a device is required - depends on, inter alia, the risk class of the respective device and the extent to which safety data is already available. Devices of the lowest risk class, class I, are mostly subject to mere self-certification by the manufacturer, while devices of higher risk classes, i.e., classes IIa, IIb and III, require a comprehensive quality system program, and other aspects to be reviewed by a Notified Body, or NB. An NB is a private entity vested with certain competencies and designated by the national governments of the EU member states to make independent judgments about whether a product complies with the EU requirements for medical devices and to grant the CE certificate if the manufacturer, and the product, comply with specified terms. After receiving the CE-certificate, we must pass a review carried out by the competent NB annually, under which it audits our facilities to verify our compliance with the ISO 13485 quality system standard. The CE-certificate is a requirement for the declaration of conformity we issue for our medical devices and for our legitimate affixing of the CE-mark to our products.

Certified compliance with the ISO 13485 standard, for medical device quality management systems, is beneficial for regulatory purposes in the EU with regard to devices of risk class IIa or higher. ISO standards are not mandatory, but are recognized international quality standards that are designed to ensure that we develop and manufacture quality medical devices. Other countries are also instituting regulations regarding medical devices. Compliance with these regulations requires extensive documentation and clinical reports for all of our products, revisions to labeling, and other requirements such as facility inspections to comply with the registration requirements.

In 2016, we received the CE certification for VergenixFG and VergenixSTR from our notified body DEKRA. These CE certifications were renewed in 2018 under the requirements of the MDD. The renewed certificates will expire on July 1, 2023, which will be extended to December 31, 2027 if the European Commissions proposed amendments to the MDR are adopted. The CE certification for VergenixWD we had has now expired, and we have not renewed it. VergenixWD was our first medical product based on collagen protein derived from plants that was authorized for sale and marketing in Europe, but we are not currently promoting a marketing strategy for VergenixWD, which is considered a commodity product and is not targeted towards the advanced wound care market, which is our target market.

Before the current CE-certificates expire, we are required to obtain new CE-certificates under the MDR. Certification under the MDR is harder to achieve, as many products are subject to increased requirements due to higher risk-classification and the fact that the MDR generally provides higher requirements. Also, our general obligations *inter alia* with regard to registration, labelling, traceability, post-market surveillance have increased now that the MDR is fully applicable.

In February 2019, we received ISO 13485 certification by DEKRA for the manufacturing and purification of our rhCollagen. The Rehovot production facility is now covered by the current CollPlant ISO13485:2016 certification that is valid until July 1, 2024.

<u>Legal Requirements for Drugs in the EU</u>

We do not believe that our products are currently subject to EU or Member States' regulation on drugs. However, given that our products are highly innovative, a risk remains that regulatory authorities, notified bodies, competitors and/or courts might be of a different opinion. Consequently, there is a risk that discussions might be started with regard to the regulatory status of our products.

If one or more of our current or future products would have the status of a drug under the law of the EU or one or more of its Member States, regulatory requirements for such product(s) would be significantly higher. In particular, a drug can only be placed on the market if it has been authorized by the competent regulatory authority either under the EU centralized procedure, the decentralized or mutual recognition procedure or under a Member State's national procedure. Marketing authorizations for drugs under all of the different authorization procedures are expensive and time consuming and require the performance of extensive pre-clinical and clinical research. If one or more of our products would be considered drugs by a regulatory authority, notified body or court of the EU or a Member State, it is possible that we would be forced to take the respective product(s) off the market until they have received marketing approval under pharmaceutical law. In addition, this might also lead to administrative fines, criminal prosecution and/or claims raised by customers and/or competitors.

**Other U.S. Federal Healthcare Laws and Regulations**

Healthcare providers, physicians, and third-party payors play a primary role in the recommendation and medical devices that are granted marketing approval. In the United States, we are subject to laws and regulations pertaining to healthcare fraud and abuse, including anti-kickback laws and physician self-referral laws that regulate the means by which companies in the healthcare industry may market their products to hospitals and healthcare providers and may compete by discounting the prices of their products. The delivery of our products is subject to regulation regarding reimbursement, and federal healthcare laws apply when a customer submits a claim for a product that is reimbursed under a federally funded healthcare program. These rules require that we exercise care in structuring our sales and marketing practices and customer discount arrangements.

Arrangements with healthcare providers, third-party payors, and other customers are subject to broadly applicable fraud and abuse and other healthcare laws and regulations, including the following:

● the federal healthcare Anti-Kickback Law prohibits, among other things, persons from knowingly and willfully soliciting, offering, receiving, or providing remuneration, directly or indirectly, in cash or in kind, to induce or reward either the referral of an individual for, or the purchase, order, or recommendation of, any good or service for which payment may be made, in whole or in part, under a federal healthcare program such as Medicare and Medicaid;

● the U.S. False Claims Act imposes civil penalties, and provides for civil whistleblower or *qui tam* actions, against individuals or entities for knowingly presenting, or causing to be presented, to the federal government, claims for payment that are false or fraudulent or making a false statement to avoid, decrease, or conceal an obligation to pay money to the federal government;

● the federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, imposes criminal and civil liability for executing a scheme to defraud any healthcare benefit program or making false statements relating to healthcare matters;

● HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act and its implementing regulations, also imposes obligations, including mandatory contractual terms, with respect to safeguarding the privacy, security, and transmission of individually identifiable health information;

● the federal false statements statute prohibits knowingly and willfully falsifying, concealing, or covering up a material fact or making any materially false statement in connection with the delivery of or payment for healthcare benefits, items, or services;

● the federal transparency requirements under the Affordable Care Act require manufacturers of drugs, devices, and medical supplies to report to the U.S. Department of Health and Human Services information related to payments, ownership and investment interest and other transfers of value to physicians, dentists, physician assistants and other health care professionals and teaching hospitals; and

● analogous state and foreign laws and regulations, such as state anti-kickback and false claims laws, may apply to sales or marketing arrangements and claims involving healthcare items or services reimbursed by non-governmental third-party payors, including private insurers.

Healthcare providers that purchase medical devices generally rely on third-party payors, including, in the United States, the Medicare and Medicaid programs and private payors, such as indemnity insurers, employer group health insurance programs, and managed care plans, to reimburse all or part of the cost of the products. As a result, demand for our products is and will continue to be dependent in part on the coverage and reimbursement policies of these payors. The manner in which reimbursement is sought and obtained varies based upon the type of payor involved and the setting in which the product is furnished and utilized. Reimbursement from Medicare, Medicaid, and other third-party payors may be subject to periodic adjustments as a result of legislative, regulatory, and policy changes as well as budgetary pressures. Possible reductions in, or eliminations of, coverage or reimbursement by third-party payors, or denial of, or provision of uneconomical reimbursement for new products, may affect our customers' revenue and ability to purchase our products. Any changes in the healthcare regulatory, payment, or enforcement landscape relative to our customers' healthcare services has the potential to significantly affect our operations and revenue.

**Other Approvals**

Our international operations, as well as being an Israeli company, subject us to laws regarding sanctioned countries, entities, and persons; customs, import-export, and laws regarding transactions in foreign countries; and the U.S. Foreign Corrupt Practices Act and local anti-bribery and other laws regarding interactions with healthcare providers. Among other things, these laws restrict, and in some cases can prevent, companies from directly or indirectly selling goods, technology, or services to people or entities in certain countries. In addition, these laws require that we exercise care in structuring our sales and marketing practices in foreign countries.

In addition to the above regulations, we are and may be subject to regulation under country-specific federal and state laws, including, but not limited to, requirements regarding record keeping and the maintenance of personal information, including personal health information. As a public company whose securities are registered pursuant to the Securities Act, we are subject to U.S. securities laws and regulations, including the Sarbanes-Oxley Act. We also are subject to other present, and could be subject to possible future, local, state, federal, and non-U.S. regulations in countries in which we will distribute our products.

***The Innovation Law and the IIA***

 ****

Below is a description of the main obligations and restrictions imposed on a Recipient Company, under the Innovation Law and the IIA's rules and guidelines, with respect to the use of the intellectual property and other know-how resulting, directly or indirectly, in whole or in part, in accordance with or as a result of, research and development activities made according to an Approved Program, as well as any rights associated with such IIA Funded Know-How:

● **Royalty Payment Obligation**. In general, the Recipient Company is obligated to pay the IIA royalties from the revenues generated from the sale of products (and related services), whether received by the Recipient Company or any affiliated entity, developed (in all or in part), directly or indirectly, as a result of an Approved Program, or deriving therefrom, at rates which are determined under the IIA's rules and guidelines (currently a yearly rate of between 3% to 5% on sales of products or services developed under the Approved Programs, depending on the type of the Recipient Company - i.e., whether it is a "Small Company," or a "Large Company" as such terms are defined in the IIA's rules and guidelines), up to the aggregate amount of the total grants received by the IIA, plus annual interest based on LIBOR (as determined in the IIA's rules and guidelines) . As of December 31, 2022, we paid royalties to the IIA in the total amount of $2.8 million.

● **Reporting Obligations**. The Recipient Company is subject to certain reporting obligations (such as, periodic reports regarding the progress of the research and development activities under the Approved Programs and the related research expenses, and regarding the scope of sales of the Recipient Company's products).

● **Local Manufacturing Obligation**. Products developed using the IIA grants must , as a general matter, be manufactured in Israel. The Recipient Company is prohibited from manufacturing products developed using these IIA grants outside of the State of Israel without receiving prior approval from the IIA (except for the transfer of less than 10% of the manufacturing capacity in the aggregate which requires only a notice, while the IIA has a right to deny such transfer within 30 days following the receipt of such notice). If the Recipient Company receives approval to manufacture products developed with IIA grants outside of Israel, it will be required (except for certain cases) to pay increased royalties to the IIA, up to 300% of the grant amount plus interest at annual rate based on LIBOR, depending on the manufacturing volume that is performed outside of Israel. The Recipient Company may also be subject to an accelerated royalty repayment rate. A Recipient Company also has the option of declaring in its IIA grant application its intention to exercise a portion of the manufacturing capacity abroad, thus avoiding the need to obtain additional approval following the receipt of the grant and avoiding the need to pay increased royalties to the IIA (it is noted, however that in such scenario the Recipient Company will be required to pay to the IIA royalties at an accelerated rate).

● **IIA Funded Know-How transfer limitation**. Under the Innovation law and the IIA's rules and guidelines, a Recipient Company is prohibited from transferring the IIA Funded Know-How outside of Israel except under limited circumstances, and only with the approval of the IIA Research Committee and in certain circumstances, subject to certain payments to the IIA calculated according to formulas provided under the IIA's rules and guidelines, or the Redemption Fee, (which are capped to amounts specified under such rules and guidelines, generally up to 6 time the grants received plus interest). For calculating the Redemption Fee which shall be paid to the IIA in the event of a transfer of IIA Funded Know-How outside of Israel, *inter alia*, the following factors will be taken into account: the scope of the IIA support received, the royalties that have already paid to the IIA, the amount of time that has lapsed since the Company has finalized the IIA Approved Program, the sale price and the form of transaction . A transfer for the purpose of the Innovation Law means an actual sale of the IIA Funded Know-How, or any other transaction which in essence constitutes a transfer of such know-how (such as, providing an exclusive license to a foreign entity for R&D purposes, which precludes the Recipient Company from further using such IIA Funded Know-How). A mere license solely to market products resulting from the IIA Funded Know-How would not be deemed a transfer for the purpose of the Innovation Law. Upon payment of the Redemption Fee, the IIA Funded Know-How and the manufacturing rights of the products supported by such IIA funding cease to be subject to the Innovation Law.

Subject to the IIA's prior approval, a Recipient Company may transfer IIA Funded Know-How to another Israeli company, provided that the acquiring company assumes all of the Recipient Company's responsibilities towards the IIA. Such transfer will not be subject to the payment of the Redemption Fee, however, the income from such sale transaction will be subject to the obligation to pay royalties to the IIA.

● **IIA Funded Know-How license limitation**. The grant to a foreign entity of a right to use the IIA Funded Know-How for R&D purposes (which does not entirely prevent the Recipient Company from using the IIA Funded Know-How) is subject to receipt of the IIA's prior approval. This approval is subject to payment to the IIA in accordance with the formulas stipulated in the IIA rules (such payment shall be no less than the amount of the IIA grants received (plus annual interest), and no more than the cap stated in the IIA rules and will generally be due only upon the receipt of the license fee from the licensee).

 ****

***Israeli Ministry of Agriculture***

The process of growth of transgenic plants and the treatment thereof is subject to the regulations published by the Israeli Ministry of Agriculture and the approval of the Ministry of Agriculture to engage in the cultivation of recombinant plants. Although the Ministry of Agriculture requirements do not necessarily apply to our operations, we hold a valid permit from the Plant Protection and Inspection Services Administration, or PPIS, for growing tobacco plants in greenhouses in our site at Yessod Hama'ala, Israel, as well as in all of our subcontractors' facilities.

***Business Licensing***

Under the Israeli Licensing of Businesses Law, to which our production sites and laboratories are subject, operating a business without a license or temporary permit is a criminal offense. In April 2019, we moved our laboratories and offices into a new site, and on September and November 2020 we have obtained a business license for our sites in Rehovot Israel. In addition, we have a business license for our production site at Yessod Hama'ala, in effect until July 18, 2025.

***Planning and Zoning***

Our production sites and laboratories are subject to the Israeli Planning and Zoning Law, which sets provisions and obligations, *inter alia*, regarding the licensing process for a new building, including building permits, non-conforming use and easements, the supervision over its construction, and the required occupancy permits. According to the Planning and Zoning Law, work or use of land without a permit where such permit is required, a deviation from the permit granted, or use of agricultural land in violation of the law, constitutes a criminal offense.

**Employees**

As of March 15, 2023, we had 73 employees, including 20 in research and development, 40 in manufacturing and 13 in sales, general and administrative positions. 15 of our employees have either MDs or PhDs. All of our employees are located in Israel. We believe our employee relations are good.

In addition, we employ a limited number of part-time employees on a temporary basis, as well as consultants and service providers.

Israeli labor laws govern the length of the workday, minimum wages for employees, procedures for hiring and dismissing employees, determination of the scope 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. We fund our ongoing severance obligations by making monthly payments to insurance policies that comply with the applicable Israeli legal requirements. All of our current employees have agreed that upon termination of their employment, they will be entitled to receive only the amounts accrued in the insurance policies with respect to severance pay. Furthermore, Israeli employers and employees are required to make payments to the National Insurance Institute, which is similar to the U.S. Social Security Administration.

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

**Environmental, Health, and Safety Matters**

Our research, development, and manufacturing processes involve the controlled use of certain hazardous materials. Therefore, we are subject to extensive environmental, health, and safety laws and regulations in a number of jurisdictions in Israel, governing, among other things: the use, storage, registration, handling, emission, and disposal of chemicals, waste materials, and sewage; chemicals, air, water, and ground contamination; air emissions; and the cleanup of contaminated sites, including any contamination that results from spills due to our failure to properly dispose of chemicals, waste materials, and sewage. Our operations at our Rehovot manufacturing facility use chemicals and produce waste materials and sewage. Our activities require permits from various governmental authorities including local municipal authorities, the Ministry of Environmental Protection, and the Ministry of Health. The Ministry of Environmental Protection, the Ministry of Health, local authorities, and the municipal water and sewage company conduct periodic inspections in order to review and ensure our compliance with various regulations.

These laws, regulations, and permits could potentially require the expenditure by us of significant amounts for compliance or remediation. We believe that our environmental, health, and safety procedures for handling and disposing of these materials comply with the standards prescribed by the controlling laws and regulations. If we fail to comply with such laws, regulations, or permits, we may be subject to fines and other civil, administrative, or criminal sanctions, including the revocation of permits and licenses necessary to continue our business activities. In addition, we may be required to pay damages or civil judgments with respect to third-party claims, including those relating to personal injury (including exposure to hazardous substances we use, store, handle, transport, manufacture, or dispose of), property damage, or contribution claims. These risks are managed to minimize or eliminate associated business impacts. Some environmental, health, and safety laws allow for strict joint and several liability for remediation costs, regardless of comparative fault. We may be identified as a responsible party under such laws. Such developments could have a material adverse effect on our business, financial condition, and results of operations as these kinds of liabilities could exceed our resources. We could be subject to a regulatory shutdown of a facility that could prevent the distribution and sale of products manufactured in such facility for a significant period of time, and we could suffer a casualty loss that could require a shutdown of the facility in order to repair it, any of which could have a material, adverse effect on our business. Although we continuously strive to maintain full compliance with respect to all applicable global environmental, health, and safety laws and regulations, we could incur substantial costs to fully comply with future laws and regulations, and our operations, business, or assets may be negatively affected.

In addition, compliance with laws and regulations relating to environmental, health, and safety matters is an ongoing process and is often subject to change. In the event of any changes or new laws or regulations, we could be subject to new compliance measures or to penalties for activities which were previously permitted. For instance, Israeli regulations were promulgated in 2012 relating to the discharge of industrial sewage into the sewer system. These regulations establish new and potentially significant fines for discharging forbidden or irregular sewage into the sewage system. We have compliance procedures in place for employee health and safety programs, driven by a centrally led organizational structure that ensures proper implementation, which is essential to our overall business objectives.

We invest resources in creating a green production environment and in the treatment and disposal of waste using environmentally friendly processes. We have received all the necessary permits from the Ministry of Environmental Protection regarding our operations in Yessod Hama'ala and we have obtained a business license for our new facilities in Rehovot. We consult with environmental consultants for direction on environmental issues.

**Legal Proceedings**

From time to time we may become involved in legal proceedings or be subject to claims arising in our ordinary course of our business. We are currently not a party to any material legal or administrative proceedings and, are not aware of any pending or threatened material legal or administrative proceedings against us.

**C. Organizational Structure**

We currently have two subsidiaries: our wholly owned subsidiary CollPlant Ltd., which is incorporated in the State of Israel, and CollPlant Inc., a wholly owned subsidiary of CollPlant Ltd., which is incorporated in Delaware.

**D. Property, Plant and Equipment**

Our corporate headquarters and research lab center are located in the Weizmann Science Park in Rehovot, Israel. We entered into a lease agreement in November 2018, for an aggregate of 13,450 square feet of office and laboratory space. In September 2021, we executed an addendum to the lease for an additional 2,800 square feet. The term of the lease is for 65 months, commencing on November 15, 2018 and ending on April 15, 2024, with an option to extend the lease for an additional five years. Monthly rent is approximately $31,000. We have invested approximately $1.5 million during the years 2021-2022 in establishment of the infrastructure, offices, labs and equipment in our space, net of participation by the landlord.

The research facilities serve us for development of our product pipeline, including BioInks for 3D bioprinting of tissues and organs, dermal fillers and breast implants for medical aesthetics and Gut-on-a-Chip models for personalized medicine and drug discovery. The majority of our research and development work is carried out at our research laboratories in Weizmann Science Park in Rehovot, Israel. The plant research process of our rhCollagen is carried out at our site in Yessod Hama'ala, Israel. We use greenhouses for tobacco growing in a few areas in Israel. We produce our rhCollagen and BioInk in our two production sites, in Yessod Hama'ala and in Rehovot.

We rent areas in Yessod Hama'ala, Israel, of approximately 64,583 square feet of greenhouse and manufacturing facility pursuant to a lease agreement expiring on April 30, 2027.

In addition, on July 28, 2016, we leased additional space in Rehovot, Israel, of approximately 6,329 square feet for production activities pursuant to a lease agreement expiring on December 31, 2026.

In late 2021, we initiated a plan to upgrade our production site in Israel into a large-scale integrated facility, in order to accommodate expected future demand increase. We have also commenced activities to establish a US-based 3D bioprinting center of excellence.

We believe that our existing facilities are adequate for our near-term needs. When our leases expire, we may look for extension periods or alternate space for our operations. We believe that suitable additional or alternative space and area would be available if required in the future on commercially reasonable terms.

Not applicable.

**ITEM 5. OPERATING AND FINANCIAL REVIEW AND PROSPECTS**

You should read the following discussion and analysis of our financial condition and results of operations together with the section titled "Item 3.A.—Selected Financial Data" and our consolidated financial statements and related notes included elsewhere in this Annual Report on Form 20-F. This discussion and other parts of this Annual Report on Form 20-F contain forward-looking statements based upon current expectations that involve risks and uncertainties. This discussion and other parts of this Annual Report on Form 20-F contain forward-looking statements that involve risk and uncertainties, such as statements of our plans, objectives, expectations, and intentions. Our actual results could differ materially from those discussed in these forward looking statements. Factors that could cause or contribute to such differences include, but are not limited to, those discussed in the section titled "Item 3.D.—Risk Factors" and elsewhere in this Annual Report in Form 20-F.

**Overview**

We are a regenerative and aesthetic medicine company focused on 3D bioprinting of tissues and organs, and medical aesthetics. Our products are based on our rhCollagen that is produced with our proprietary plant based genetic engineering technology. Our products address indications for the diverse fields of tissue repair, aesthetics and organ manufacturing, and, we believe, are ushering in a new era in regenerative and aesthetic medicine. Our collaborations include, among others, AbbVie, STEMCELL, Tel Aviv University, Sheba Medical Center, ARMI and ReMDO.

Our flagship rhCollagen BioInk product line is ideal for 3D bioprinting of tissues and organs. We are developing 3D bioprinted breast implants for regeneration of breast tissue and aim to provide a revolutionary alternative to the current practices. The implants in development will be bioprinted and loaded with compositions that are based on rhCollagen and ECM components. These implants are intended to promote tissue regeneration and degrade in synchronization with the development of a natural breast tissue. In addition, we are in collaboration with AbbVie under a Development, Exclusivity and Option Products Agreement, pursuant to which we and AbbVie in the development and commercialization of dermal and soft tissue filler products for the medical aesthetics market, using our rhCollagen technology and AbbVie's technology.

To date, we have financed our operations primarily with revenues from sales of our products and license of our technology, as well as from net proceeds from private and public offerings. Prior to February 2017, we financed our operations primarily from public offerings of our securities on the TASE, participation of business partners in product development collaborations, and government grants from the IIA.

Since our inception, we have incurred significant losses, except for the year ended December 31, 2021. Our net loss was $16.9 million for the year ended December 31, 2022 and our net income was $237,000 for the year ended December 31, 2021. As of December 31, 2022, we had an accumulated deficit of $89.7.

We expect to continue to incur expenses and operating losses for the foreseeable future. The net losses we incur may fluctuate significantly from quarter to quarter. We anticipate that our expenses will increase substantially if and as we:

● continue our research and preclinical and clinical development of our pipeline products;

● seek marketing approvals for our products and future products in the United States and other new territories;

● maintain, expand, and protect our intellectual property portfolio;

● hire additional operational, clinical, quality control, and scientific personnel;

● establish plant infrastructure to accommodate product capacity increase;

● add operational, financial, and management information systems and personnel, including personnel to support our product development, any future commercialization efforts, and our transition to a public reporting company in the United States; and

● identify additional product candidates.

**Financial Operations Overview**

***Revenue***

Our ability to generate significant revenues will depend on the successful commercialization of our rhCollagen-based BioInks and products, and on our ability to establish and maintain business collaborations with leading companies for 3D bioprinting of organs and tissues, and for medical aesthetics. In the year ended December 31, 2022, we generated revenues of $299,000 mainly from sales of our BioInk and rhCollagen.

Our revenues are recorded in the amount of consideration to which we expect to be entitled in exchange for performance obligations upon transfer of control to the customer.

 ****

***Operating Expenses***

<u>Cost of Revenue</u>

Cost of revenues in our proprietary products and services includes expenses for the manufacturing of products such as raw materials, payroll, utilities, laboratory costs, share-based compensation and depreciation. Cost of revenue also includes provisions for the costs associated with manufacturing scraps and inventory write offs.

<u>Research and Development Expenses</u>

Research and development expenses consist of costs incurred for the development of our rhCollagen-based products. 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;

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

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

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

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

● costs associated with preclinical and clinical activities.

Research and development activities are the primary focus of our business. Products 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. We expect that our research and development expenses will continue to be significant in absolute dollars in future periods as we continue to invest in research and development activities related to the development of our products.

Our total research and development expenses for the years ended December 31, 2022, December 31, 2021, and December 31, 2020 were $10.3 million, $7.6 million, and $4.1 million, respectively. We did not apply for grants from the IIA since 2019 and we have charged all research and development expenses to operations as they are incurred.

There are numerous factors associated with the successful commercialization of any of our products, including future trial design and various regulatory requirements, many of which cannot be determined with accuracy at this time. Additionally, future commercial and regulatory factors beyond our control will affect our clinical development programs and plans.

<u>Participation in Research and Development Expenses</u>

Our research and development expenses are net of the following participations by third parties.

 ****

***Participation by the Israel Innovation Authority.*** Until 2019 we have applied and received grants from the IIA as part of the research and development programs for our rhCollagen technology and our products. The requirements and restrictions for such grants are found in the Encouragement of Research, Development and Technological Innovation in the Industry Law 5744 1984 (formerly known as the Law for the Encouragement of Research and Development in Industry 5744 1984) ("Innovation Law"), and the regulations promulgated thereunder. These grants are subject to repayment through future royalty payments on any products resulting from these research and development programs, including VergenixSTR and VergenixFG. Under the Innovation Law royalties of 3% on the income generated from sales of products and from related services developed in whole or in part under IIA programs are payable to the IIA, up to the total amount of grants received, linked to the U.S. dollar and bearing interest at an annual rate of LIBOR applicable to U.S. dollar deposits, as published on the first business day of each calendar year. The total gross amount of grants actually received by us from the IIA as of December 31, 2022 totaled approximately $10.1 million. As of December 31, 2022, we paid royalties to the IIA in the total amount of $2.8 million.

In addition to paying any royalty due, we must abide by other restrictions associated with receiving such grants under the Innovation Law that continue to apply following repayment to the IIA. These restrictions may impair our ability to outsource manufacturing 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. For more information, see "Item 3.D. Risk Factors—Risks Related to Our Financial Condition and Capital Requirements—The IIA grants we have received for research and development expenditures may restrict our ability to manufacture products and transfer know-how outside of Israel and require us to satisfy specified conditions." If we fail to comply with the Innovation Law, we may be subject to civil claims and criminal charges.

Under applicable accounting rules, the grants from the IIA have been accounted for as an off-set against the related research and development expenses in our financial statements. Our balance sheet liabilities include current obligations regarding royalties that we are obligated to pay to the IIA based on sales of our products for the second half of the year, as they are due for payment in the following quarter. Our cost of goods include royalties expenses regarding royalties on our sales to the IIA See Note 6 in our consolidated financial statements for the year ended December 31, 2022 for more information.

 ****

<u>General, Administrative, and Marketing Expenses</u>

Our general and administrative expenses consist principally of:

● employee-related expenses, including salaries, benefits, and related expenses, including share-based compensation expenses;

● legal and professional fees for auditors, investor relations, and other consulting expenses not related to research and development activities;

● cost of offices, communication, and office expenses;

● information technology expenses;

● business development and marketing activities;

● Stock exchange fees and related services; and

● Board members related expenses, including fees and directors' liability insurance premiums.

We expect that our general, administrative, and marketing expenses will increase in the future as our business expands and we incur additional general and administrative costs associated with being a public company in the United States, including compliance under the Sarbanes-Oxley Act and rules promulgated by the SEC. These public company-related increases will likely include costs of additional personnel, additional legal fees, audit fees, directors' liability insurance premiums, and costs related to investor relations.

<u>Financial Income/Financial Expense</u>

Financial income includes interest income regarding short-term cash deposits and re-evaluation of financial instruments. Financial expense consists of bank commissions.

<u>Taxes on Income</u>

We do not generate taxable income in Israel, as we have historically incurred operating losses resulting in carry forward tax losses. As of December 31, 2022, we have incurred operating losses of approximately $21.5 million for CollPlant Biotechnologies Ltd. and $66.3 million for CollPlant Ltd. We anticipate that we will be able to carry forward these tax losses indefinitely to future tax years assuming that we utilize them at the first opportunity. Accordingly, we do not expect to pay taxes in Israel until we have taxable income after the full utilization of our carry forward tax losses.

The standard corporate tax rate in Israel is 23%. Under the Investment Law, and other Israeli laws, we may be entitled to certain additional tax benefits, including reduced tax rates, accelerated depreciation, and amortization rates for tax purposes on certain assets and amortization of other intangible property rights for tax purposes.

<u>Revenues</u>

We generated revenues from the sale of our BioInk, rhCollagen, and VergenixFG of $299,000 in the year ended December 31, 2022 compared to $15.6 million for the year ended December 31, 2021. The decrease in revenues mainly derived from the $14 million consideration for the license granted to AbbVie and to a decrease in sales of BioInk and Vergenix products.

We generated revenues from the sale of our BioInk, rhCollagen, VergenixFG and VergenixSTR, as well as revenues from the AbbVie Agreement, in the year ended December 31, 2021 of approximately $15.6 million compared to $6.1 million in the year ended December 31, 2020. The increase in revenues in 2021 was mainly related to the $14.0 million consideration for the license granted to AbbVie.

<u>Cost of revenue</u>

We incurred cost of revenue in the amount of $400,000 in the year ended December 31, 2022, compared to $2.0 million in the year ended December 31, 2021. The decrease in cost of revenues in the amount of approximately $1.6 million is mainly comprised of: (i) approximately $460,000 in royalty expenses to the IIA and (ii) approximately $1 million relating to BioInk, VergenixFG, and rhCollagen sales.

We incurred cost of revenue in the amount of $2.0 million in the year ended December 31, 2021, compared to $3.0 million in the year ended December 31, 2020. Cost of revenue includes mainly the cost of VergenixFG, VergenixSTR and our rhCollagen based BioInk products, and royalties to the IIA for our sales.

**JOBS Act**

With less than $1.235 billion in revenues during our last fiscal year, we qualify as an emerging growth company under the JOBS Act. An emerging growth company may take advantage of specified provisions in the JOBS Act that provide exemptions or reductions of its regulatory burdens related to reporting and other requirements that are otherwise applicable generally to public companies. These provisions include an exemption from the auditor attestation requirement in the assessment of our internal control over financial reporting pursuant to the Sarbanes-Oxley Act. We may take advantage of some, but not necessarily all, of these provisions to reduce our burdens or exempt ourselves from regulatory requirements for up to five years or such earlier time that we are no longer deemed an emerging growth company. We will be an emerging growth company until the earliest of: (i) the last day of the fiscal year during which we had total annual gross revenues of $1.235 billion or more, (ii) the last day of the fiscal year following the fifth anniversary of the date of the first sale of our common equity securities pursuant to an effective registration statement (i.e. December 31, 2023), (iii) the date on which we have, during the previous three-year period, issued more than $1 billion in non-convertible debt, or (iv) the date on which we are deemed a "large accelerated filer" as defined in Regulation S-K under the Securities Act.

**B. Liquidity and Capital Resources**

Our primary uses of cash are to fund working capital requirements, research and development expenses and capital expenditures. Historically, we have funded our operations primarily through cash flow from operations (including sales of our proprietary products and distribution products), payments received in connection with strategic partnerships (including milestone payments from collaboration agreements), issuances of ordinary shares and warrants (including public offerings on the Tel Aviv Stock Exchange, Nasdaq Global Market and private placements) and government grants from the IIA. The balance of cash and cash equivalents as of December 31, 2022 and 2021 totaled $29.7 million and $13.1 million, respectively. In February 2021 we completed a registered direct offering that resulted in gross proceeds of $35 million and in the same month, we received a $14 million consideration for the license granted to AbbVie under the Development Agreement. We plan to fund our future operations through continued sales of our proprietary products, commercialization and or out-licensing of our rhCollagen and BioInk technology, and raising additional capital through the issuance of equity or debt.

Our cash requirements from known contractual obligations within the next twelve months include:

● Lease liabilities in the amount of $709,000. For more information see Note 5 to our consolidated financial statements for the year ended December 31, 2022; and

● Trade and other payables in the amount of $2.6 million, which include amounts related to suppliers, salaries and other liabilities with payment term of less than one year.

Our long-term cash requirements under our various contractual obligations include:

● Lease liabilities in the amount of $2.8 million. For more information, see Note 5 to our consolidated financial statements for the year ended December 31, 2022.

<u>Net Cash Provided by (Used in) Operating Activities</u>

The use of cash resulted primarily from our net income in the year ended December 31, 2021, and from our net losses in the years ended December 31, 2022 and 2020, adjusted for non-cash charges and measurements and changes in components of working capital. Adjustments to net income for non-cash items include depreciation and amortization and share-based compensation.

Net cash used in operating activities resulted primarily from our net income or losses adjusted for non-cash charges and measurements and changes in components of working capital. Adjustments to net loss for non-cash items include depreciation and amortization, share-based compensation and exchange differences on cash and cash equivalents. This cash flow mainly reflects the cash needed for funding the products and pipeline products development and costs of the Company's management during the applicable periods.

Net cash used in operating activities in the year ended December 31, 2022 totaled $13.7 million and consisted primarily of (i) net loss of $16.9 million, adjusted for non-cash items including depreciation of $1.1 million, shared-based compensation of $2.2 million, net decrease in operating lease accounts of $455,000, gains from short-term cash deposits of $87,000, and (ii) a net change in operating assets and liabilities of $482,000.

Net cash provided by operating activities in the year ended December 31, 2021 totaled $2.5 million and consisted primarily of (i) a net income of $237,000, adjusted for non-cash items including depreciation of $773,000, shared-based compensation of $1.6 million, gains from short term bank deposits of $151,000 and change in financial instruments of $28,000, and (ii) a net decrease in operating assets and liabilities of $216,000, which are mainly attributable to a decrease in trade receivables of $560,000, and a decrease in accrued liabilities of $464,000 mainly due to royalty payment to the IIA.

Net cash used in operating activities in the year ended December 31, 2020 totaled $4.4 million and consisted primarily of (i) a net loss of $5.8 million, adjusted for non-cash items including depreciation of $660,000, shared-based compensation of $1.7 million and change in financial instruments of $40,000, and (ii) a net increase in operating assets and liabilities of $911,000, which are mainly attributable to an increase in trade receivables of $751,000 mainly due to royalty payment to the IIA, and an increase in inventory of $374,000.

<u>Net Cash Provided by (Used in) Investing Activities</u>

Net cash provided by investing activities was $28.9 million during the year ended December 31, 2022 and $31.6 million used in during the year ended December 31, 2021. The change is mainly attributed to repayment and investment in short term cash deposits.

Net cash used in investing activities was $31.6 million during the year ended December 31, 2021 and $519,000 during the year ended December 31, 2020. The increase in the amount of approximately $31.0 million is primarily due to short term cash deposits of $30.0 million.

Net cash used in investing activities was $519,000 during the year ended December 31, 2020 and $1.5 million during the year ended December 31, 2019. The decrease in the amount of approximately $942,000 in investing activities is primarily due to the establishment of our new center of R&D labs and headquarters in Rehovot in 2019.

<u>Net Cash Provided by Financing Activities</u>

Net cash provided by financing activities was $1.9 million for the year ended December 31, 2022 compared to $38.8 million in the year ended December 31, 2021. The decrease is mainly attributed to our registered direct offering in February 2021, which resulted in net proceeds of $32 million and decrease of $4.1 million in proceeds in exercise of options and warrants.

Net cash provided by financing activities amounted to approximately $38.8 million for 2021 and $4.5 million in 2020. In 2021, we consummated equity raises of net $32.7 million in return for proceeds from the issuances of securities under a registered direct offering and $6.0 million in return for proceeds from exercise of options and warrants.

Net cash provided by financing activities amounted to approximately $4.5 million for 2020 and $5.4 million in 2019.

***Funding Requirements***

We believe that our existing cash and cash equivalents and short term cash deposits, as of the date of this Annual Report on Form 20-F, which includes approximately $29.6 million, will enable us to fund our operating expenses and capital expenditures for at least the next 12 months. We have based this estimate on assumptions that may prove to be wrong, and we could use our capital resources sooner than we currently expect.

Our present and future funding requirements will depend on many factors, including, among other things:

● the number of potential new products we identify and decide to develop;

● the progress, timing, and completion of preclinical testing and clinical trials in the U.S. for tissues and organs which are based on our BioInk, medical aesthetics, and any future pipeline product;

● selling and marketing activities undertaken in connection with the commercialization of our products;

● the costs of upscaling our manufacturing capabilities;

● costs involved in the development of distribution channels, and for an effective sales and marketing organization, for the commercialization of our products in Europe;

● the time and costs involved in obtaining regulatory approvals and any delays we may encounter as a result of evolving regulatory requirements or adverse results with respect to any of these products; and

● the costs involved in filing patent applications and maintaining and enforcing patents or defending against claims or infringements raised by third parties.

For more information as to the risks associated with our future funding needs, see "Item 3.D. Risk Factors—We will need to raise additional funding, which may not be available on acceptable terms, or at all. Failure to obtain additional capital when needed may force us to delay, limit, or terminate our product development efforts or other operations."

**C. Research and Development, Patents and Licenses**

See above, under Item 5 – "Research and Development Expenses."

**D. Trend Information**

We are in a development stage with regard to different 3D BioInks and medical aesthetics products, and are in early stages of commercialization of our BioInks for customers that develop technologies for 3D bio-printing of tissues and organs and the medical aesthetics market. It is not possible for us to predict with any degree of accuracy the outcome of our research, development, or commercialization efforts. As such, it is not possible for us to predict with any degree of accuracy any known trends, uncertainties, demands, commitments or events that are reasonably likely to have a material effect on our net sales or revenues, income from continuing operations, profitability, liquidity or capital resources, or that would cause reported financial information to not necessarily be indicative of future operating results or financial condition. However, to the extent possible, certain trends, uncertainties, demands, commitments and events are in this "Operating and Financial Review and Prospects."

**E. Critical Accounting Estimates**

Our critical accounting estimates include the areas where we have made what we consider to be particularly difficult, subjective or complex judgments in making estimates, and where these estimates can significantly affect our financial results under different assumptions and conditions. We prepare our financial statements in conformity with GAAP. As a result, we are required to make estimates, judgments and assumptions that we believe are reasonable based upon the information available. These estimates, judgments and assumptions affect the reported amounts of assets and liabilities at the date of the financial statements and reported amounts of revenue and expenses during the periods presented. Actual results could be different from these estimates. Critical estimates and assumptions made by management include:

***Estimates of share-based compensation fair value***

Share-based compensation reflects the compensation expense of our share option programs granted to employees which compensation expense is measured at the grant date fair value of the options. The grant date fair value of share-based compensation is recognized as an expense over the requisite service period. We recognize compensation expense for awards conditioned only on continued service that have a graded vesting schedule using the accelerated method based on the multiple-option award approach, and classify these amounts in our statement of operations based on the department to which the related employee reports.

*Options Valuation*

We selected the Black-Scholes option pricing model as the most appropriate method for determining the estimated fair value of the share-based compensation.

For the purpose of the evaluation of the fair value and the manner of the recognition of share-based compensation, our management is required to estimate, among others, various subjective and complex parameters that are included in the calculation of the fair value of the option as well as our results and the number of options that will vest. These parameters include the expected volatility of our share price over the expected term of the options, the risk-free interest rate assumption, the share option exercise and expected dividends.

**Compensation of Directors**

Until May 2022, we paid our directors (other than our Chairman) annual fees of approximately $8,400 and a per meeting fee of approximately $500, in accordance with regulations promulgated under the Companies Law. On May 2, 2022, following the approval of our compensation committee and board of directors, our general meeting of shareholders approved an amendment to the compensation of directors, which was subject to the approval of our new compensation policy (which was obtained in the same shareholders' meeting), such that all directors (other than the Chairman) are entitled to an annual fee of $25,000 and a per meeting participation fee of $800, and any applicable VAT as well as reimbursement of expenses, including meeting participation expenses, reimbursement of business travel including a daily stipend when traveling and accommodation expenses.

Our Chairman is entitled to a monthly consulting fee of $14,584 plus applicable VAT as well as reimbursement, against receipts, for out-of-pocket business expenses, reasonably and necessarily incurred by him relating to the provision of his services, provided that our prior approval for such expense has been obtained.

The members of our board of directors are also entitled to a letter of indemnification and exculpation, in the Company's standard form, and to coverage under our D&O insurance policies, as renewed from time to time.

In May 2021, we granted, subject to shareholders approval which was obtained on August 4, 2021, Hugh Evans options to purchase 23,000 ordinary shares, at an exercise price of $15.2. The options vest subject to a vesting period of four years, with a quarter of the options vesting on the first anniversary of the grant date, and the remaining options vesting in equal parts at the end of every quarter thereafter.

In May 2022, we granted, subject to shareholders approval which was obtained on May 2, 2022, options to purchase 50,000 ordinary shares to our Chairman, Dr. Roger Pomerantz, options to purchase 24,000 ordinary shares to each of Dr. Avraham (Avri) Havron, Dr. Elan Penn, Dr. Gili Hart, Joseph Zarzewsky, and Hugh Evans, as well as options to purchase 47,000 ordinary shares to Ms. Alisa Lask, who was appointed as a member of our board of directors in the same general meeting of shareholders. The exercise price of these options is $9.22 per one ordinary share. The options will be exercisable for ten years following the date of grant, and vest subject to a vesting period of four years, with a quarter of the options vesting on the first anniversary of the grant date, and the remaining options vesting in equal parts at the end of every quarter thereafter. The remaining terms of the options are in accordance with the 2010 Plan, which includes conditions with respect to, among other things, acceleration, adjustments, assumption, and termination of engagement.

**Employment and Services Agreements with Senior Management**

We have entered into written employment agreements with each of our executive officers. These agreements provide for notice periods of varying duration for termination of the agreement by us or by the relevant executive officer, during which time the executive officer will continue to receive base salary and benefits. These agreements also contain customary provisions regarding noncompetition, confidentiality of information and assignment of inventions. However, the enforceability of the noncompetition provisions may be limited under applicable law.

For information on exemption and indemnification letters granted to our directors and officers, please see "C. Board Practices – Exculpation, Insurance and Indemnification of Directors and Officers".

**C. Board Practices**

**Board of Directors**

Under the Companies Law, the overseeing of 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 officers are responsible for our day-to-day management and have individual responsibilities established by our board of directors and specified in their specific employment agreements. 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 officers are appointed by our chief executive officer with the prior review of our board of directors and compensation committee, and are subject to the terms of any applicable employment agreements that we may enter into with them.

Under our articles of association, our board of directors must consist of at least three and not more than twelve directors, including at least two external directors, but allows us, subject to and in accordance with the provisions of any law, to determine that the provisions relating to external directors (including the obligation to appoint external directors) shall not apply to us.

Prior to the 2019 Financing, we considered ourselves as a company with no controlling shareholder, and therefore, in November 2018, our board of directors decided to adopt an exemption, or the Exemption, that provides relief for Israeli companies whose shares are listed on certain stock exchanges outside of Israel (including the Nasdaq Capital Market) with no controlling shareholder from being required to appoint external directors so long as such companies satisfy the requirements of the foreign laws in the listing jurisdiction outside of Israel which apply to companies incorporated in such jurisdiction, in respect of the appointment of independent directors and the composition of the audit committee and compensation committee. Our articles of association were amended to reflect such relief on June 6, 2019. Accordingly, the former external directors, Dr. Gili Hart and Dr. Elan Penn, were no longer classified as external directors, but continued to serve on our board of directors. As part of the 2019 Financing, Mr. Sagy increased his holdings in the Company to over 25%, at which point we determined that we will consider Mr. Sagy as our controlling shareholder. Under these circumstances, we could no longer benefit from the Exemption and approached the Israeli Ministry of Justice to re-classify Dr. Gili Hart and Dr. Elan Penn as external directors despite changes in their compensation package adopted during the period in which they were not classified as external directors, at which point in time the Israeli Ministry of Justice notified us that under the circumstances, there was no prevention from re-classifying Dr. Gili Hart and Dr. Elan Penn as external directors, and accordingly, we re-classified Dr. Gili Hart and Dr. Elan Penn as our external directors until the remainder of their term on July 4, 2020 and January 14, 2021, respectively, considering among other things, the short time that lapsed from the date on which we adopted the Exemption and the formation of a control interest in the Company as well as the fact that Dr. Gili Hart and Dr. Elan Penn do not have any affiliation with Mr. Sagy. On May 14, 2020, at our extraordinary general meeting of shareholders, our shareholders re-elected Dr. Gili Hart as an external director of the Company for a three-year term until July 5, 2023. On October 13, 2020, at our annual and extraordinary general meeting of shareholders, our shareholders re-elected Dr. Elan Penn as an external director of the Company for a three-year term until January 14, 2024.

On December 20, 2021, our board of directors determined that in light of our current shareholding structure, which no longer supports the claim that we have a controlling shareholder, it was decided to reinstate the relief provided under the Exemption. As such, Dr. Gili Hart and Dr. Elan Penn were no longer classified as external directors, as of which date they continue to serve on our board of directors as independent directors until the earlier of: (i) the end of their tenure; or (ii) the lapse of the second annual general meeting following the said determination.

Currently our board of directors consists of seven non-employee directors, all of who are elected annually at the general meeting of our shareholders by a vote of the holders of a majority of the voting power present and voting, in person or by proxy, at that meeting, other than Dr. Gili Hart and Dr. Elan Penn, who, as aforesaid, shall continue to serve until the earlier of: (i) the end of their tenure; or (ii) the lapse of the second annual general meeting following the determination that we no longer have a controlling shareholder, and Mr. Yehiel Tal, who was appointed as a director on May 25, 2022 by our board of directors and shall continue to serve until the next annual general meeting.

We have two types of directors: independent directors and "regular" directors. For purposes of complying with the Nasdaq Listing Rules to list the Company's ordinary shares on the Nasdaq Global Market, our board of directors is comprised of seven independent directors and one regular director.

Our board of directors has determined that all of our non-employee directors are independent under such rules.

Under the Companies Law any shareholder holding at least 1% of our outstanding voting power may propose to nominate one or more persons for election as directors at a general meeting by delivering a written notice of such shareholder's intent to make such nomination or nominations to our registered office. Each such notice must set forth all of the details and information as required to be provided by our amended and restated articles of association and regulations promulgated under the Companies law.

In addition, our articles of association allow our board of directors to appoint additional director or directors who shall remain in office until the next annual shareholders' meeting, provided that the board of directors must consist of no more than 12 directors. In addition, our articles of association allow our board of directors to appoint alternate 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. In determining the number of directors required to have such expertise, our board of directors must consider, among other things, the type and size of the company and the scope and complexity of its operations. 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, companies incorporated under the laws of the State of Israel that are "public companies", including companies with shares listed on the Nasdaq, are required to appoint at least two external directors. The external directors must meet strict independence criteria to ensure that they are unaffiliated with the company and any controlling shareholder. At least one of the external directors is required to have financial and accounting expertise, and the other external director must have either financial and accounting expertise or professional qualifications, as defined in the regulations promulgated under the Companies Law. The Companies Law also provides that the external directors must serve on both the audit committee and the compensation committee, that the audit committee and the compensation committee must both be chaired by an external director, and that at least one external director must serve on every board committee authorized to exercise powers of the board of directors. Additional rules govern the term and compensation of external directors. Pursuant to regulations promulgated under the Companies Law, companies with shares traded on certain U.S. stock exchanges, including the Nasdaq, may, subject to certain conditions, "opt out" from the Companies Law requirements to appoint external directors and related Companies Law rules concerning the composition of the audit committee and compensation committee of the Board of Directors. In accordance with these regulations, we have elected to "opt out" from the Companies Law requirement to appoint external directors and related Companies Law rules concerning the composition of the audit committee and compensation committee of the Board of Directors.

As discussed above, until December 20, 2021, Dr. Gili Hart and Dr. Elan Penn served as "external directors" on our board of directors, and upon the determination of our board of directors that the Company no longer has a controlling shareholder, continue to serve as independent directors on our board of directors until the earlier of: (i) the end of their tenure; or (ii) the lapse of the second annual general meeting following the said determination.

For further information on our decision to "opt out" pursuant to the Exemption, please see C. Board Practices – Board of Directors.

**Role of Board of Directors 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 of Directors**

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

**Committees of the Board of Directors**

Currently, our board of directors has three permanent committees: an audit committee, a compensation committee, and a nominating and corporate governance committee.

***Audit Committee***

Under the Companies Law, the board of directors of a public company must appoint an audit committee that will comply with certain composition requirements, subject to the possibility of a company to opt out of certain Companies Law requirements under certain circumstances, as we have. Under the Nasdaq Listing Rules, 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.

Accordingly, our audit committee consists of Dr. Gili Hart, Dr. Elan Penn and Joseph Zarzewsky, each of whom meets the requirements for independence under the rules of the Nasdaq and the applicable rules and regulations of the SEC. Each member of our audit committee also meets the financial literacy requirements in the rules of the Nasdaq and the applicable rules and regulations of the SEC. In addition, our board of directors has determined that Dr. Elan Penn is an audit committee financial expert within the meaning of Item 407(d) of Regulation S-K under the Securities Act.

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 the Nasdaq Listing 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 mainly 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 certain acts of an office holder not in accordance with his or her fiduciary duty owed to the Company are extraordinary or material and to approve such acts and 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" below);

● determining procedures for a competitive process, or other procedures, before approving related party transactions with controlling shareholders, even if such transactions are deemed by the audit committee not to be extraordinary transactions. This process is to be supervised by the audit committee, or any person authorized for such supervision, or via any other method approved by the audit committee;

● determining whether or not to approve acts or transactions that require the audit committee's approval pursuant to the Companies Law.

● determining the approval process for transactions that are not negligible, as well as determine which types of transactions would require the approval of the audit committee. Non-negligible transactions are defined as related party transactions with a controlling shareholder, or in which the controlling shareholder has a personal interest, even if they are deemed by the audit committee not to be extraordinary transactions but which have also been classified by the audit committee as non-negligible transactions;

● 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;

● 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 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" below), unless at the time of approval a majority of the committee's members are present.

 ****

***Compensation Committee***

Under the Companies Law, the board of directors of a public company must appoint a compensation committee. The Companies Law provides composition requirements applicable to a compensation committee, unless a company elects to opt-out of certain Companies Law requirements, under certain circumstances, as we have. Our compensation committee consists of Dr. Elan Penn, Alisa Lask and Joseph Zarzewsky, each of whom meets the requirements for independence under the rules of the Nasdaq Global Market and the applicable rules and regulations of the SEC.

The duties of the compensation committee include the recommendation to the company's board of directors of a policy regarding the terms of engagement of office holders, to which we refer as a compensation policy, and to examine the necessity of updating the compensation policy. This policy must be adopted by the company's board of directors, after considering the recommendations of the compensation committee, and must be approved by the company's shareholders, which approval requires a special majority, which we refer to as a Special Majority for Compensation. This Special Majority for Compensation 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: (i) 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 (ii) 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. Under special circumstances, the board of directors may approve the compensation policy despite the objection of the shareholders on the condition that the compensation committee (or the audit committee acting in lieu of a compensation committee pursuant to the Companies Law) and then the board of directors decides, on the basis of detailed arguments and after discussing the compensation policy once again, that approval of the compensation policy, despite the objection of the meeting of shareholders, is for the benefit of the company. Our current compensation policy was approved by our shareholders on May 2, 2022 by the required Special Majority for Compensation, and will be in effect for a period of three years from its date of approval. The compensation policy does not, by nature, grant any rights to our directors or officers. The compensation policy includes both long-term and short-term compensation elements and is to be reviewed from time to time by our compensation committee and our board of directors, according to the requirements of the Companies Law.

Our compensation policy serves 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 with respect to employment or engagement. According to the Companies Law, the compensation policy must be approved (or reapproved) not longer than every three years and 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. With respect to the compensation terms that include variable compensation, the compensation policy must also consider the officer holders' contribution to meeting the Company's objectives and the creation of profit, all with a long-term view and according to the office holder's position. 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 ratio between the terms offered and the cost of employment of the other employees of the company, including those employed through manpower companies, and in particular the ratio between the average salary and the median salary of such employees;

● 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 capping 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 objectives 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 linkage between variable compensation and long-term performance and measurable criteria.

● the ratio between variable and fixed compensation, and the ceiling for the value of variable compensation at the time of the payment (or with respect to variable equity compensation that is not paid for in cash, a ceiling for their value on the grant date);

● 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 with a view to long-term incentives; and

● maximum limits for severance compensation.

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.

**Approval of Related Party Transactions under Israeli Law**

***Fiduciary Duties of Directors and Officers***

The Companies Law imposes a duty of care and a fiduciary duty on all office holders of a company. Each person listed in the table under "Management—Senior Management and Directors" is an office holder under the Companies Law.

The duty of care requires an office holder to act with the degree of proficiency with which a reasonable office holder in the same position would have acted under the same circumstances. The fiduciary duty 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 fiduciary duty includes a duty to:

● refrain from any act involving a 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 solely 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.

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

● a transaction other than in our 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 which is not an extraordinary transaction, approval by the board of directors is required for such transaction, unless the company's articles of association provide for a different method of approval. 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. In general, 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 shareholders' approval by the Special Majority for Compensation. Arrangements regarding the compensation, exculpation, 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.

Generally, a person who has a personal interest in a matter which is being 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) have 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 (except in cases where specific reliefs are applied).

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

Under Israeli Law, the term "controlling shareholder" means a shareholder with the ability to direct the activities of our company, other than by virtue of being an officer or director. A shareholder is presumed to be a controlling shareholder if the shareholder holds 50% or more of the voting rights in a company or has the right to appoint at least half of the directors of the company or its general manager. For the purpose of approving transactions with related parties, the definition of controlling shareholder also includes any shareholder that holds 25% or more of the voting rights in a public company if no other shareholder holds more than 50% of the voting rights in the company. For purposes of determining the holding percentage stated above, two or more shareholders who have a personal interest in a transaction that is brought for the company's approval are deemed as joint holders.

Pursuant to Israeli law, the disclosure requirements regarding personal interests that apply to directors and officers also apply to a controlling shareholder of a public company. In the context of a transaction involving a shareholder of the company, as mentioned above, 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 examined on an aggregate basis and will be deemed as joint holders. Generally, the approval of the audit committee or compensation committee, the board of directors, and a special majority, in that order, is required for: (i) extraordinary transactions with a controlling shareholder or in which a controlling shareholder has a personal interest, including any private placements in which a controlling shareholder has a personal interest; (ii) the engagement with a controlling shareholder or his or her relative, directly or indirectly, for the provision of services to the company; (iii) the terms of engagement and compensation of a controlling shareholder or his or her relative who is an office holder; or (iv) the employment of a controlling shareholder or his or her relative by the company. For this purpose, 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 do not have a personal interest in the approval of such item; or (b) the total number of shares of non-controlling shareholders and shareholders who do not have a personal interest in the approval of such item and who vote against the arrangement does not exceed 2% of the company's aggregate voting rights.

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, exculpation, indemnification, or insurance of a controlling shareholder in his or her capacity as an office holder require the approval of the compensation committee and board of directors, and, in general, approval by a special majority of shareholders.

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 or compensation committee and board of directors.

 ****

***Shareholders' Duties***

Under the Companies Law, a shareholder has a duty to act in good faith and in a customary manner toward the company and other shareholders and to refrain from abusing his or her power in the company, including, among other things, in voting at general meetings of shareholders and class meetings of shareholders with respect to the following matters:

● an amendment of the articles of association or memorandum of association of the company;

● an increase in the company's authorized share capital;

● a merger; or

● the approval of related party transactions and acts of office holders that require shareholder approval.

A shareholder also has a general duty to refrain from discriminating against other shareholders. In addition, certain shareholders have a duty of fairness toward the company. These shareholders include any controlling shareholder, any shareholder who knows that he or she has the power to determine the outcome of a shareholder vote and any shareholder who has the power to appoint or to prevent the appointment of an office holder of the company or other power. The Companies Law does not define the substance of the duty of fairness, except to state that the remedies generally available upon a breach of contract will also apply in the event of a breach of the duty to act with fairness.

 ****

***Exculpation, Insurance and Indemnification of Directors and Officers***

Under the Companies Law, a company may not exculpate an office holder from liability for a breach of the duty of loyalty. An Israeli company may exculpate an office holder in advance from liability to the company, in whole or in part, for damages caused to the company as a result of a breach of duty of care but only if a provision authorizing such exculpation is included in its articles of association. Our articles of association include such a provision. A company may not exculpate a director from liability arising out of a prohibited dividend or distribution to shareholders.

Under the Companies Law, an Israeli company may indemnify an office holder with respect to the following liabilities and expenses incurred for acts performed as an office holder, either in advance of an event or following an event, provided a provision authorizing such indemnification is contained in its articles of association:

● financial liability imposed on him or her in favor of another person pursuant to a judgment, including a settlement or arbitrator's award approved by a court. However, if an undertaking to indemnify an office holder with respect to such liability is provided in advance, then such an undertaking must be limited to events which, in the opinion of the board of directors, can be foreseen based on the company's activities when the undertaking to indemnify is given, and to an amount or according to criteria determined by the board of directors as reasonable under the circumstances, and such undertaking must detail the abovementioned foreseen events and amount or criteria;

● reasonable litigation expenses, including attorneys' fees, incurred by the office holder: (i) as a result of an investigation or proceeding instituted against him or her by an authority authorized to conduct such investigation or proceeding, provided that (a) no indictment was filed against such office holder as a result of such investigation or proceeding and (b) no financial liability was imposed upon him or her as a substitute for the criminal proceeding as a result of such investigation or proceeding or, if such financial liability was imposed, it was imposed with respect to an offense that does not require proof of criminal intent; and (ii) in connection with a monetary sanction;

● Expenses incurred in connection with an Administrative proceeding that has been conducted in his case, including reasonable litigation costs, covering also legal fees. "**Administrative proceeding**" - a proceeding to impose a financial sanction according to Article D of Chapter Four of Part 9 of the Companies Law as amended from time to time; as well as proceeding according to Chapter a G1 of the Restrictive Trade Practices Law, 5748-1988, as amended from time to time; as well as any additional administrative proceeding whereby, by law (and subject to that law) an indemnity may be granted in respect of payments related thereto or expenses incurred in connection therewith; and,

● reasonable litigation expenses, including attorneys' fees, incurred by the office holder or imposed by a court in proceedings instituted against him or her by the company, on its behalf, or by a third party or in connection with criminal proceedings in which the office holder was acquitted or as a result of a conviction for an offense that does not require proof of criminal intent.

Under the Companies Law, a company may insure an office holder against the following liabilities incurred for acts performed as an office holder if, and to the extent, provided in the company's articles of association:

● a breach of duty of care to the company or to a third party, including a breach arising out of the negligent conduct of the office holder;

● a breach of fiduciary duty to the company, to the extent that the office holder acted in good faith and had a reasonable basis to believe that the act would not prejudice the company;

● a monetary liability imposed on the office holder in favor of a third party; and

● expenses incurred by an office holder in connection with an administrative procedure, including reasonable litigation expenses and reasonable attorneys' fees.

Under the Companies Law, a company may not indemnify or insure an office holder against any of the following:

● a breach of fiduciary duty, except for indemnification and insurance for a breach of the fiduciary duty to the company and to the extent that the office holder acted in good faith and had a reasonable basis to believe that the act would not prejudice the company;

● a breach of duty of care committed intentionally or recklessly, excluding a breach arising out of the negligent conduct of the office holder;

● an act or omission committed with intent to derive illegal personal benefit; or

● a fine or forfeit levied against the office holder.

Under the Companies Law, exculpation, indemnification, and insurance of office holders in a public company must be approved by the compensation committee and the board of directors and, with respect to certain office holders or under certain circumstances, by the shareholders.

Our articles of association and compensation policy allow us to exculpate, indemnify, and insure our office holders according to applicable law.

We have obtained directors' and officers' liability insurance for the benefit of our office holders and intend to continue to maintain such coverage and pay all premiums thereunder to the fullest extent permitted by the Companies Law. In addition, we have entered into agreements with each of our current office holders undertaking to indemnify them to the fullest extent permitted by the Companies Law and our articles of association, to the extent that these liabilities are not covered by insurance.

In the opinion of the Securities and Exchange Commission, indemnification of directors and office holders for liabilities arising under the Securities Act, however, is against public policy and therefore unenforceable.

**D. Employees.**

See "Item 4.B. Business Overview—Employees."

**E. Share Ownership.**

See "Item 7.A. Major Shareholders" below.

**Share Incentive Plan**

In May 2010, we adopted the 2010 Plan, an option plan for employees and senior officers, and as part of the acquisition of CollPlant Ltd., all of the options under the Employee Share Ownership and Option Plan (2004) of CollPlant Ltd. were substituted with and assumed by options under our 2010 Plan, while any restriction periods under Sections 102(b)(2) and 102(b)(3) of the Israeli Income Tax Ordinance, or the Ordinance, were calculated as of their original grant date. On March 26, 2020, our board of directors, in accordance with the compensation committee's recommendation, extended the 2010 Plan for an additional ten (10) years period, until May 2030. The 2010 Plan allows us to grant options to purchase our ordinary shares to our officers, employees, and consultants. The 2010 Plan is intended to enhance our ability to attract and retain desirable individuals by increasing their ownership interests in us. As of March 15, 2023, our employees, officers, directors and consultants hold an aggregate of options to purchase 1,844,652 ordinary shares, NIS 1.50 par value, under the 2010 Plan. Since 2008 and until March 15, 2023, options to purchase an aggregate of 203,348 ordinary shares had been exercised and transferred to the beneficial holders. The 2010 Plan is designed to reflect the provisions of the Israeli Income Tax Ordinance, or the Ordinance, mainly Sections 102 and 3(i), 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. Sections 102(b)(2) and 102(b)(3) of the Ordinance, which provide the most favorable tax treatment for grantees, permit 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, our ability to deduct an expense with respect to the issuance of the options or shares might be limited. Section 3(i) of the Ordinance does not provide for similar tax benefits.

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 plan, 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 transfer to an Administrator in accordance with law in the event of the absence of legal competency. 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 board of directors, and with respect to grants to a director or officer, by the compensation committee prior to the board of directors, and is specified in each option award agreement. In general, and according to our compensation policy, the option exercise price is the market value of the shares on the date of grant in accordance with our ordinary share market value traded on the Nasdaq Global Market.

Awards under the 2010 Plan may be granted until 2030, 10 years from the date on which the 2010 Plan was extended by our board of directors.

Options granted under the 2010 Plan generally vest over four years commencing on the date of grant such that 25% vest on the first anniversary of the date of grant and an additional 6.25% vest at the end of each subsequent three-month period thereafter for 36 months , unless otherwise provided in a specific allocation agreement.

Options, other than certain incentive share options, that are not exercised within 10 years from the grant date expire, unless otherwise determined by our board of directors. 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, 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, death, or retirement. If we terminate a grantee's employment or service for cause, all of the grantee's unvested options will expire on the date of termination, yet options which by that date the offeree's eligibility to exercise has already been formed shall remain exercisable. 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 (i) a sale of all or substantially all of our assets or (ii) our consolidation or merger in which we are not the ongoing or surviving corporation, then, and unless otherwise determined in the agreement or by the board, we shall be entitled to determine that all of the outstanding unexercised options held by or for the benefit of any grantee shall be assumed or substituted for an appropriate number of options of the successor company, provided that the aggregate amount of the exercise price for such options shall be equal to the aggregate amount of the exercise price of our unexercised options held by each grantee at such time. With respect to the grants that were made since October 2017, the above acceleration provision was amended in a manner that the options' vesting is fully accelerated upon the occurrence of a M&A Transaction or Reorganization: (1) "M&A Transaction" shall mean a "merger" as such term or term of similar nature is defined in the Israeli Companies Law of 1999, as well as (i) a sale of 50% or more of the assets of the Company and its subsidiaries taken as a whole, or the sale or disposition (whether by merger or otherwise) of one or more subsidiaries of the Company if more than 50% of the assets of the Company and its subsidiaries taken as a whole are held by such subsidiary or subsidiaries; (ii) a sale of all or more than 50% of the shares of the share capital of the Company whether by a single transaction or a series of related transactions which occur either over a period of 12 months or within the scope of the same acquisition agreement; (iii) an issuance of shares of the Company, whether by a single transaction or a series of related transactions which occur either over a period of 12 months or within the scope of the same acquisition agreement, that results in the offeree holding more than 50% of the share capital of the Company; or (iv) a merger, consolidation or like transaction of the Company with or into another corporation including a reverse triangular merger, but excluding a merger which falls within the definition of Reorganization; and/or (2) "Reorganization" shall mean any re-domestication of the Company, share flip, creation of a holding Company for the Company which will hold all, or 50% or more, of the shares of the Company or any other transaction involving the Company in which our ordinary shares of the Company outstanding immediately prior to such transaction continue to represent, or are converted into or exchanged for shares that represent, immediately following such transaction, at least a majority, by voting power, of the share capital of the surviving, acquiring or resulting corporation and in which there is no material change to the interests held by the shareholders of the Company prior to such transaction and thereafter.

The Board may also determine that in the occurrence of a Fund-Raising Transaction (as defined below), that all of the outstanding and unexercised options held by or for the benefit of any grantee shall become fully vested. Such determination shall be specifically determined in the grantee's letter of grant. "Fund-Raising Transaction" shall mean the raise by the Company of at least $10 million by way of public offerings and/or private placements of equity securities by one transaction or more, except in the event of issuance of equity securities in connection with the grant in exchange for services or as part of a commercial transaction.

**F. Disclosure of a registrant's action to recover erroneously awarded compensation.**

Not applicable.

**ITEM 7. MAJOR SHAREHOLDERS AND RELATED PARTY TRANSACTIONS**

**A. Major Shareholders**

The following table sets forth information with respect to the beneficial ownership of our ordinary shares as of March 15, 2023 by:

● each of our directors and senior management;

● all of our directors and senior management as a group; and

● each person (or group of affiliated persons) known by us to be the beneficial owner of 5% or more of the outstanding ordinary shares.

Beneficial ownership is determined in accordance with the rules of the SEC. These rules generally attribute beneficial ownership of securities to persons who possess sole or shared voting or investment power with respect to those securities, and include shares subject to options and warrants that are exercisable within 60 days after March 15, 2023. Such shares are also deemed outstanding for purposes of computing the percentage ownership of the person holding the option, but not the percentage ownership of any other person.

Unless otherwise indicated below, to our knowledge, all persons named in the table have sole voting and investment power with respect to their shares, except to the extent that authority is shared by spouses under community property laws. None of our shareholders has informed us that he, she, or it is affiliated with a registered broker-dealer or is in the business of underwriting securities. None of our shareholders has different voting rights from other shareholders.

**Registration Rights Agreement Relating to our 2019 Financing Agreement**

Concurrently with the execution of a financing agreements entered into in 2019 with Ami Sagy and certain U.S. Investors, or the 2019 Financing, we entered into registration rights agreements, or the Registration Rights Agreements, with each of Ami Sagy and the U.S. Investors. Pursuant to the Registration Rights Agreements, we granted one demand registration right to each of Mr. Sagy and the U.S. Investors, which expired in October 2021. In addition, we granted to each of Mr. Sagy and the U.S. Investors F-3 shelf registration rights, pursuant to which Mr. Sagy and the U.S. Investors can demand the filing of a shelf registration statement or a public offering under such shelf registration statement, but not more than twice during any 12-month period. We also granted to Mr. Sagy and the U.S. Investors certain piggyback registration rights. All registration rights granted relate to ordinary shares held by Mr. Sagy and the U.S. Investors as well as the ordinary shares to be issued upon exercise of any warrants issued to Mr. Sagy and the U.S. Investors in the 2019 Financing.

As part of the Registration Rights Agreements, we granted customary indemnification rights pursuant to which we undertook to indemnify Mr. Sagy and the U.S. Investors, as the case may be, from and against all Losses (as such term is defined in the Registration Rights Agreements) arising out of or relating to any untrue or alleged untrue statement or omission or alleged omission of a material fact contained in a registration statement and violations of securities laws in connection with the Registration Rights Agreements. Moreover, Mr. Sagy and the U.S. Investors undertook to indemnify us, severally and not jointly, from and against all Losses arising out of or relating to any untrue or alleged untrue statement of a material fact or omission or alleged omission of a material fact contained in any registration statement, but only to the extent that such untrue statement or omission is contained in any information furnished in writing by Mr. Sagy or the U.S. Investors, as the case may be.

We further undertook to bear all fees and expenses incident to the performance of or compliance with the Registration Rights Agreements, whether or not any registerable securities are sold pursuant to a registration statement. This will include all registration and filing fees, printing expenses, communication and delivery expenses, fees and disbursements of counsel for the Company, Securities Act liability insurance (should we desire such insurance), and the fees and expenses of all other persons retained by us in connection with the consummation of the Registration Rights Agreements.

**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.

**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 benefit us. This section also contains a discussion of material Israeli tax consequences concerning the ownership and disposition of our ordinary shares. 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. To the extent that the discussion is 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 resident (as defined below) companies, such as us, are generally subject to corporate tax at the rate of 23% as of 2018. However, the effective tax rate payable by a company that derives income from a Preferred Enterprise or a Preferred Technology Enterprise (as discussed below) may be considerably lower. 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, or the Industry Encouragement Law, provides several tax benefits for "Industrial Companies."

The Industry Encouragement Law defines an "Industrial Company" as a company 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. 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 a patent and know-how which were purchased in good faith and are used for the development or advancement of the Industrial Enterprise;

● deduction over a three-year period of expenses incurred in connection with the issuance and listing of shares on a stock market; and

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

There can be no assurance that we currently qualify, or will continue to qualify, as an Industrial Company or that the benefits described above will be available in the future.

***Law for the Encouragement of Capital Investments, 5719-1959***

 

*Tax Benefits for Income from Preferred Enterprise*

The Law for the Encouragement of Capital Investments, 5719-1959, or the Investment Law, currently provides certain tax benefits for income generated by "Preferred Companies" from their "Preferred Enterprises." The definition of a Preferred Company includes, *inter alia,* a company incorporated in Israel that is not wholly owned by a governmental entity, which:

● owns a Preferred Enterprise, which is defined as an "Industrial Enterprise" (as defined under the Investment Law) that is classified as either a "Competitive Enterprise" (as defined under the Investment Law) or a "Competitive Enterprise in the Field of Renewable Energy" (as defined under the Investment Law);

● is controlled and managed from Israel;

● is not a "Family Company," a "Home Company," or a "Kibbutz" (collective community) as defined under the Income Tax Ordinance;

● keeps acceptable books of account and files reports in accordance with the provisions of the Investment Law and the Income Tax Ordinance; and

● was not, and certain officers of which were not, convicted of certain crimes in the 10 years prior to the tax year with respect to which benefits are being claimed.

As of January 1, 2017, a Preferred Company is currently 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 area A, in which case the rate is currently 7.5% (our operations are currently not located in development area A).

Dividends distributed from income generated from a Preferred Enterprise are subject to tax at the rate of 20% or to a lower rate as may be provided in an applicable tax treaty. However, if such dividends are distributed to an Israeli company, such dividends are exempt from tax.

If in the future we generate taxable income, to the extent that we qualify as a "Preferred Company," the benefits provided under the Investment Law could potentially reduce our corporate tax liabilities. Therefore, the termination or substantial reduction of the benefits available under the Investment Law could materially increase our tax liabilities.

 

*Tax Benefits for Income from Preferred Technology Enterprise*

An amendment to the Investment Law was enacted as part of the Economic Efficiency Law that was published on December 29, 2016, and became effective as of January 1, 2017, or the 2017 Amendment. The 2017 Amendment provides new tax benefits to Preferred Companies for "Technology Enterprises," as described below, and is in addition to the Preferred Enterprise regime provided under the Investment Law.

The 2017 Amendment provides that a technology company that meet the conditions established in law will be qualified as a "Preferred Technology Enterprise" and may thereby benefit from a reduced corporate tax rate of 12% on its "Preferred Technology Income," as defined in the Investment Law. The applicable tax corporate tax rate can be reduced to 6%-12% present (6% in case the company has a turnover of over 10 billion NIS, and to 12% in case the company has less than 10 billion NIS of a turnover. In case the company is located in a development area A and has a turnover of less than 10 billion, it will be eligible for 7.5% tax rate). In addition, a Preferred Technology Enterprise may be subjected to a reduced capital gains tax rate of 12% and up to 6% (depending on the company's turnover) on capital gain derived from the sale of certain "Benefited Intangible Assets" (as defined in the Investment Law) to a related foreign company. A company can be eligible to reduced tax rates only in case the Benefited Intangible Assets was acquired or registered on behalf of the company or after January 1, 2017 (applicable to companies with a turnover of more than 10 billion NIS), or in case the Benefited Intangible Assets were acquired from a foreign company on or after January 1, 2017 for at least NIS 200 million and the sale receives prior approval from the IIA (applicable to companies with a turnover of less than 10 billion NIS).

Dividends distributed by a Preferred Technology Enterprise that are paid out of Preferred Technology Income are subject to tax at the rate of 20%, but if such dividends are distributed to a foreign company and at least 90% of the shares of the distributing company are held by foreign resident companies then the tax rate may be as low as 4%, subject to the fulfillment of certain conditions.

As we have not yet generated taxable income, there is no assurance that we qualify as a Preferred Technology Enterprise or that the benefits described above will be available to us in the future.

If in the future we generate taxable income, to the extent that we qualify as a "Preferred Company," the benefits provided under the Investment Law could potentially reduce our corporate tax liabilities. Therefore, the termination or substantial reduction of the benefits available under the Investment Law could materially increase our tax liabilities.

***The Encouragement of Research, Development and Technological Innovation in the Industry Law 5744***

Under the Encouragement of Research, Development and Technological Innovation in the Industry Law 5744-1984 (formerly known as the Law for the Encouragement of Research and Development in Industry 5744-1984), or Innovation Law, and the regulations and guidelines promulgated thereunder, research and development programs which meet specified criteria and are approved by a committee of the IIA, are eligible for grants. The grants awarded are typically up to 50% of the project's expenditures, as determined by the research committee. The grantee is required to pay royalties to the State of Israel from the sale of products developed under the program. Regulations under the Innovation Law generally provide for the payment of royalties of 3% to 6% on income generated from products and services based on technology developed using grants, until 100% of the grant, linked to the dollar and bearing interest at the LIBOR rate, is repaid. In July 2017, new regulations came into force. According to the new regulations, the royalties range between 1.3-5% depending on the company's size and sector. The terms of the IIA participation also require that products developed with IIA grants be manufactured in Israel and that the know-how developed thereunder may not be transferred outside of Israel, unless approval is received from the IIA and additional payments are made to the IIA. However, this does not restrict the export of products that incorporate the funded know-how. The royalty repayment ceiling can reach up to three times the amount of the grant received (plus interest) if manufacturing is transferred outside of Israel, and repayment of up to six times the amount of the grant (plus interest) may be required if the technology itself is transferred outside of Israel or license to use it was granted to a foreign entity.

 ****

***Taxation of our Shareholders***

 

*Capital Gains Tax*

Israeli law generally imposes a capital gains tax (i) on the sale of any capital assets by residents of Israel, as defined for Israeli tax purposes, and (ii) on the sale of capital assets located in Israel, including shares of Israeli companies, by non-residents of Israel, unless a specific exemption is available or unless a tax treaty between Israel and the shareholder's country of residence provides otherwise. The law distinguishes between real gain and inflationary surplus. The inflationary surplus is a portion of the total capital gain that is equivalent to the increase of the relevant asset's purchase price which is attributable to the increase in the Israeli consumer price index or a foreign currency exchange rate between the date of purchase and the date of sale. The real gain is the excess of the total capital gain over the inflationary surplus.

<u>Israeli Residents</u>

Generally, as of January 1, 2012 and thereafter, the tax rate applicable to real capital gains derived from the sale of shares, whether listed on a stock market or not, is 25% for Israeli individuals, unless such shareholder claims a deduction for financing expenses in connection with such shares, in which case the gain will generally be taxed at a rate of 30%. Additionally, if such shareholder is considered a "substantial shareholder" at the time of the sale or at any time during the 12-month period preceding such sale, the tax rate will be 30%. A "substantial shareholder" is defined as one who holds, directly or indirectly, alone or "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), holds, directly or indirectly, at least 10% of any of the "means of control" in the company. "Means of control" generally include the right to vote, receive profits, nominate a director or an executive officer, receive assets upon liquidation, or instruct someone who holds any of the aforementioned rights regarding the manner in which such rights are to be exercised. However, different tax rates will apply to dealers in securities. Israeli companies are subject to capital gains tax at the regular corporate tax rate (i.e., 23% for the tax year 2018 and thereafter) on real capital gains derived from the sale of listed shares.

As of January 1, 2020, Israeli resident shareholders who are individuals with taxable income that exceeds NIS 651,600 in a tax year (linked to the Israeli consumer price index each year) will be subject to an additional tax at the rate of 3% on the portion of their taxable income for such tax year that exceeds NIS 651,600 (linked to the Israeli consumer price index each year). For this purpose, taxable income includes taxable capital gains from the sale of our shares and taxable income from dividend distributions.

In some instances where our shareholders are liable for Israeli tax on the sale of their ordinary shares, the payment of the consideration may be subject to the withholding at source of Israeli tax at source.

<u>Non-Israeli Residents</u>

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 in Israel (and also if the company was not listed on stock exchange, under certain conditions) will be exempt from Israeli tax so long as the shares were not held through a permanent establishment that the non-resident maintains in Israel. However, non-Israeli resident corporations will not be entitled to the foregoing exemption if (i) an Israeli resident has a controlling interest, directly or indirectly, alone, "together with another" (as defined above), or together with another Israeli resident, of more than 25% in one or more of the "means of control" (as defined above) 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.

In addition, 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, pursuant to the provisions 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, as amended, or the U.S.-Israel Tax Treaty, capital gains arising from the sale, exchange or disposition of our ordinary shares by (i) a person who qualifies as a resident of the United States within the meaning of the U.S.-Israel Tax Treaty, (ii) who holds the shares as a capital asset, and (iii) who is entitled to claim the benefits afforded to such person by the U.S.-Israel Tax Treaty generally is generally exempt from Israeli capital gains tax. Such exemption will not apply if: (i) such person holds, directly or indirectly, shares representing 10% or more of our voting power during any part of the 12-month period preceding such sale, exchange, or disposition, subject to particular conditions; (ii) the capital gains from such sale, exchange, or disposition are attributable to a permanent establishment in Israel; or (iii) such person is an individual and was present in Israel for 183 days or more during the relevant tax year. In such case, the capital gain arising from the sale, exchange, or disposition of our ordinary shares would be subject to Israeli tax, to the extent applicable; however, under the U.S.-Israel Tax Treaty, the taxpayer may 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 U.S.-Israel Tax Treaty does not relate to U.S. state or local taxes.

Shareholders may be required to demonstrate that they are exempt from tax on their capital gains in order to avoid withholding tax at source at the time of sale.

It should be noted that in the event that the real capital gain realized by an individual shareholder is not exempt from tax in Israel, the tax rates applicable to Israeli resident individual shareholders should generally apply.

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.

 

*Taxation of Dividend Distributions*

<u>Israeli Residents</u>

Israeli resident individuals are generally subject to Israeli income tax on the receipt of dividends paid in respect to ordinary shares, other than bonus shares (share dividends). As of January 1, 2012 and thereafter, the tax rate applicable to such dividends is generally 25%. With respect to a person who is a "substantial shareholder" (as defined above) at the time the dividend is received or at any time during the preceding 12-month period, the applicable tax rate is 30%. Dividends distributed from income derived from Preferred Enterprises and Preferred Technology Enterprises will generally be subject to income tax at a rate of 20%.

As of January 1, 2020, Israeli resident shareholders who are individuals with taxable income that exceeds NIS 651,600 in a tax year (linked to the Israeli consumer price index each year) will be subject to an additional tax at the rate of 3% on the portion of their taxable income for such tax year that exceeds NIS 651,600 (linked to the Israeli consumer price index each year). For this purpose, taxable income includes taxable capital gains from the sale of our shares and taxable income from dividend distributions.

Dividends paid to an Israeli resident individual shareholder on our ordinary shares will generally be subject to withholding tax at the rates corresponding with the income tax rates detailed above unless we are provided in advance with a withholding tax certificate issued by the Israel Tax Authority stipulating a different rate.

Notwithstanding the above, dividends distributed to an Israeli resident "substantial shareholder" (as defined above) on publicly traded shares, like our ordinary shares, which are held via a "nominee company" (as defined under the Israeli Securities Law), 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 Israel Tax Authority allowing for a reduced withholding tax rate is obtained in advance.

If the dividend is attributable partly to income derived from a Preferred Enterprise or a Preferred Technology Enterprise and partly to other sources of income, the tax rate will be a blended tax rate reflecting the relative portions of the various types of income. We cannot assure you that we will designate the profits that are being distributed in a way that will reduce shareholders' tax liability.

Israeli resident companies are generally exempt from tax on the receipt of dividends paid on our ordinary shares.

<u>Non-Israeli Residents</u>

Unless relief is provided in a treaty between Israel and the shareholder's country of residence, non-Israeli residents are generally subject to Israeli income tax on the receipt of dividends paid on our ordinary shares at the rate of 25%. With respect to a person (including a corporation) who is a "substantial shareholder" (as defined above) at the time of receiving the dividend or at any time during the preceding 12-month period, absent treaty relief as mentioned above, the applicable capital gains tax rate is 30%. Notwithstanding the above, dividends distributed from income derived from Preferred Enterprises will be subject to Israeli tax at a rate of 20%. In addition, dividends distributed by a Preferred Technology Enterprise that are distributed from a Preferred Technology Income are subject to tax at the rate of 20%, but if they are distributed to a foreign company and at least 90% of the shares of the distributing company are held by foreign resident companies then the tax rate may be as low as 4%, subject to the fulfillment of certain conditions.

In this regard, dividends paid to a non-Israeli resident shareholder on our ordinary shares will generally be subject to withholding tax at the rates corresponding with the income tax rates detailed above unless we are provided in advance with a withholding tax certificate issued by the Israel Tax Authority stipulating a different rate (e.g., in accordance with the provisions of an applicable tax treaty).

Notwithstanding the above, dividends paid to a non-Israeli resident "substantial shareholder" (as defined above) on publicly traded shares, like our ordinary shares, which are held via a "nominee company" (as defined under the Israeli Securities Law), 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 Israel Tax Authority allowing for a reduced withholding tax rate is obtained in advance.

In addition, it should be noted that an additional 3% tax might be applicable to individual shareholders if certain conditions are met.

Under the U.S.-Israel Tax Treaty, the maximum Israeli tax on dividends paid to a holder of ordinary shares who qualifies as a resident of the United States within the meaning of the U.S.-Israel Tax Treaty is 25%. Such tax rate is generally reduced to 12.5% if: (i) the shareholder is a U.S. corporation and holds at least 10% of the outstanding shares of our voting stock during the part of our tax year that precedes the date of payment of the dividends and during the whole of our prior tax year; (ii) not more than 25% of our gross income in the tax year preceding the payment of the dividends consists of interest or dividends, other than dividends or interest received from subsidiary corporations that 50% or more of the outstanding shares of voting stock of such corporations are owned by us at the time such dividends or interest are received by us; and (iii) the dividends are not sourced from income derived during a period for which we were entitled to the reduced tax rate applicable to a Preferred Enterprise under the Investment Law. If the dividends are sourced from income derived during a period for which we are entitled to the reduced tax rate applicable to a Preferred Enterprise or a Preferred Technology Enterprise under the Investment Law, to the extent that the first two conditions detailed above are met, the Israeli tax rate applicable to such dividends should be 15%.

If the dividend is attributable partly to income derived from a Preferred Enterprise or a Preferred Technology Enterprise and partly to other sources of income, the tax rate will be a blended rate reflecting the relative portions of the various types of income. We cannot assure you that we will designate the profits that are being distributed in a way that will reduce shareholders' tax liability.

<u>Estate and gift tax</u>

Israeli law presently does not impose estate tax.

Israeli law also does not presently impose gift taxes upon the transfer of assets to Israeli resident individuals so long as it is demonstrated to the satisfaction of the Israel Tax Authority that the transfer was executed in good faith.

**Material U.S. Federal Income Tax Consequences**

The following summary describes certain material U.S. federal income tax consequences relating to an investment in our ordinary shares. This summary deals only with ordinary shares that are held as capital assets (generally, property held for investment) within the meaning of Section 1221 of the U.S. Internal Revenue Code of 1986, as amended, or the Code, and does not address tax considerations of holders that may be subject to special tax rules, including, but not limited to, dealers or traders in securities or currencies, financial institutions, tax-exempt organizations, insurance companies, regulated investment companies, real estate investment trusts, grantor trusts, individual retirement and tax-deferred accounts, certain former citizens or residents of the United States, persons who acquire our ordinary shares through the exercise or cancellation of employee stock options or otherwise as compensation for their services, persons holding ordinary shares as part of a hedging, integrated, conversion or constructive sale transaction, or a straddle, persons that mark their securities to market for U.S. federal income tax purposes, persons subject to the alternative minimum tax, or persons who have a functional currency other than the U.S. dollar. In addition, this discussion does not address the tax treatment of U.S. holders (as defined below) who own, directly, indirectly, or constructively, 10% or more of our outstanding stock, by vote or value. The summary set forth below relating to U.S. holders is applicable only to such U.S. holders (i) who are residents of the United States for purposes of the U.S.-Israel Tax Treaty, (ii) whose ordinary shares are not, for purposes of the U.S.-Israel Tax Treaty, effectively connected with or attributable to a permanent establishment in Israel, and (iii) who otherwise qualify for the full benefits of the U.S.-Israel Tax Treaty. The discussion below is based upon the Code, final, temporary and proposed Treasury regulations promulgated thereunder, applicable administrative rulings and judicial interpretations thereof, and the U.S.-Israel Tax Treaty, all as in effect as of the date of this Annual Report on Form 20-F and all of which are subject to change, possibly on a retroactive basis, and all of which are open to differing interpretations. In addition, this summary does not consider the possible application of U.S. federal gift or estate taxes or any aspect of state, local, or non-U.S. tax laws. Furthermore, we will not seek a ruling from the IRS with regard to the U.S. federal income tax treatment of an investment in our ordinary shares and can provide no assurance that the tax consequences contained in this summary will not be challenged by the IRS or will be sustained in a court if challenged.

As used in this summary the term "U.S. holder" means a beneficial owner of ordinary shares that is, for U.S. federal income tax purposes: (i) an individual citizen or resident of the United States, (ii) a corporation (or other entity taxable as a corporation for U.S. federal income tax purposes) created or organized in or under the laws of the United States or any state thereof, or the District of Columbia; (iii) an estate the income of which is subject to U.S. federal income taxation regardless of its source, or (iv) a trust if either (a) a court within the United States is able to exercise primary supervision over the administration of the trust and one or more U.S. persons have the authority to control all substantial decisions of the trust, or (b) the trust has a valid election in effect under applicable Treasury regulations to be treated as a U.S. person. Except to the limited extent discussed below, this summary does not consider the U.S. federal tax considerations to a person that is not a U.S. holder (a "non-U.S. holder"). In addition, the tax treatment of persons who hold ordinary shares through a partnership or other pass-through entity treated as a partnership for U.S. federal income tax purposes generally depends upon the status of the partner (or person or entity treated as a partner) and the activities of the partnership. The tax consequences to such a partner or partnership are not considered in this summary and partners and partnerships should consult their tax advisors with respect to the U.S. federal tax consequences of investing in our ordinary shares.

**This summary does not discuss all aspects of U.S. federal income taxation that may be relevant to a particular investor in light of its circumstances. Prospective purchasers of our ordinary shares should consult their own tax advisors with respect to the specific U.S. federal income tax consequences to such person of purchasing, holding, or disposing of our ordinary shares, as well as the effect of any state, local, or other tax laws.**

***Distributions on Ordinary Shares***

As noted above, we currently do not expect to pay cash dividends on our ordinary shares in the foreseeable future. Subject to the discussion under the heading "Passive Foreign Investment Company Consequences," U.S. holders are required to include in gross income the amount of any distribution paid on ordinary shares to the extent the distribution is paid out of our current and/or accumulated earnings and profits, as determined for U.S. federal income tax purposes. To the extent a distribution paid with respect to our ordinary shares exceeds our current and accumulated earnings and profits, such amount will be treated first as a non-taxable return of capital, reducing a U.S. holder's tax basis for our ordinary shares to the extent thereof, 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. Preferential tax rates for long-term capital gains are applicable for U.S. holders that are individuals, estates, or trusts. However, we do not expect to maintain calculations of our earnings and profits under United States federal income tax principles. Therefore, U.S. holders should expect that the entire amount of any distribution (without reduction for any Israeli tax withheld from such distribution) generally will be reported as dividend income when actually or constructively received. The amount of the dividend will generally be treated as foreign-source dividend income to U.S. holders. A non-corporate U.S. holder that meets certain eligibility requirements may qualify for a lower rate of U.S. federal income taxation on dividends paid if we are a "qualified foreign corporation" for U.S. federal income tax purposes. We generally will be treated as a qualified foreign corporation if we are not a passive foreign investment company, or PFIC, in the taxable year in which such dividends are paid or in the preceding taxable year (see discussion below), and (i) we are eligible for benefits under the United States-Israel income tax treaty or (ii) our ordinary shares are listed on an established securities market in the United States (which includes the Nasdaq Global Market). In addition, a non-corporate U.S. holder will not be eligible for a reduced U.S. federal income tax rate with respect to dividend distributions on ordinary shares if (a) such U.S. holder has not held our ordinary shares for at least 61 days during the 121-day period starting on the date which is 60 days before, and ending 60 days after the ex-dividend date, (b) to the extent the U.S. holder is under an obligation to make related payments on substantially similar or related property, or (c) with respect to any portion of a dividend that is taken into account by the U.S. holder as investment income under Section 163(d)(4)(B) of the Code. Any days during which the U.S. holder has diminished its risk of loss with respect to ordinary shares (for example, by holding an option to sell our ordinary shares) are not counted towards meeting the 61-day holding period. Non-corporate U.S. holders should consult their own tax advisors concerning whether dividends received by them qualify for the reduced rate of tax.

Corporate U.S. holders generally will not be allowed a deduction for dividends received from us.

The amount of a distribution with respect to our ordinary shares equals the amount of cash and the fair market value of any property distributed plus the amount of any Israeli taxes withheld therefrom. The amount of any cash distributions paid in NIS equals the U.S. dollar value of the NIS on the date of distribution based upon the exchange rate in effect on such date, regardless of whether the NIS are converted into U.S. dollars at that time, and U.S. holders who include such distribution in income on such date will have a tax basis in such NIS for U.S. federal income tax purposes equal to such U.S. dollar value. If the dividend is converted to U.S. dollars on the date of receipt, a U.S. holder generally will not recognize a foreign currency gain or loss. However, if the U.S. holder converts the NIS into U.S. dollars on a later date, the U.S. holder must include, in computing its income, any gain or loss resulting from any exchange rate fluctuations. The gain or loss will be equal to the difference between (i) the U.S. dollar value of the amount included in income when the dividend was received and (ii) the amount received on the conversion of the NIS into U.S. dollars. Such gain or loss will generally be ordinary income or loss and United States source income for U.S. foreign tax credit purposes. U.S. holders should consult their own tax advisors regarding the tax consequences to them if we pay dividends in NIS or any other non-U.S. currency.

Subject to certain significant conditions and limitations, including potential limitations under the U.S.-Israel Tax Treaty, U.S. holders may be entitled to a credit against their U.S. federal income tax liability or a deduction against U.S. federal taxable income in an amount equal to the non-refundable Israeli tax withheld on distributions on our ordinary shares. However, as a result of recent changes to the U.S. foreign tax credit rules, a withholding tax generally will need to satisfy certain additional requirements in order to be considered a creditable tax for a U.S. holder. We have not determined whether these requirements have been met and, accordingly, no assurance can be given that any withholding tax on dividends paid by us will be creditable. The election to deduct, rather than credit, foreign taxes, is made on a year-by-year basis and applies to all foreign taxes paid by a U.S. holder or withheld from a U.S. holder that year. Distributions paid on our ordinary shares will generally be treated as passive income that is foreign source for U.S. foreign tax credit purposes, which may be relevant in calculating a U.S. holder's foreign tax credit limitation. The rules relating to the determination of the foreign tax credit are complex, and U.S. holders should consult their own tax advisors to determine whether and to what extent they would be entitled to such credit.

 ****

***Disposition of Ordinary Shares***

Subject to the discussion under the heading "Passive Foreign Investment Company Consequences," upon the sale, exchange or other disposition of ordinary shares, a U.S. holder generally will recognize capital gain or loss in an amount equal to the difference between the amount realized on the disposition and such U.S. holder's adjusted tax basis in our ordinary shares. The adjusted tax basis in an ordinary share generally will be equal to the cost of such ordinary share. The capital gain or loss realized on the sale, exchange, or other disposition of ordinary shares will be long-term capital gain or loss if the U.S. holder held our ordinary shares for more than one year as of the time of disposition. Preferential tax rates for long-term capital gain will generally apply to non-corporate U.S. holders. Any gain or loss realized by a U.S. holder on the sale, exchange, or other disposition of ordinary shares generally will be treated as from sources within the United States for U.S. foreign tax credit purposes, except for certain losses which will be treated as foreign source to the extent certain dividends were received (or certain inclusion amounts were taken into account) by the U.S. holder within the 24-month period preceding the date on which the U.S. holder recognized the loss. The deductibility of capital losses for U.S. federal income tax purposes is subject to limitations.

U.S. holders should consult their own tax advisors regarding the U.S. federal income tax consequences of receiving currency other than U.S. dollars upon the disposition of their ordinary shares.

 ****

***Disclosure of Reportable Transactions***

If a U.S. holder sells or disposes of our ordinary shares at a loss or otherwise incurs certain losses that meet certain thresholds, such U.S. holder may be required to file a disclosure statement with the IRS. Failure to comply with these and other reporting requirements could result in the imposition of significant penalties.

***Passive Foreign Investment Company Consequences***

Generally, a non-U.S. corporation will be a PFIC for U.S. federal income tax purposes in any taxable year in which either (i) 75% or more of its gross income for such year consists of certain types of "passive" income or (ii) 50% or more of the average fair market value of its assets during such year (based on quarterly valuations) produce or are held for the production of passive income. Passive income for this purpose generally includes dividends, interest, rents, royalties, annuities, income from certain commodities transactions and from notional principal contracts, and the excess of gains over losses from the disposition of assets that produce passive income. Passive income also includes amounts derived by reason of the temporary investment of funds, including those raised in a public offering. Assets that produce or are held for the production of passive income may include cash, even if held as working capital or raised in a public offering, as well as marketable securities, and other assets that may produce passive income. In determining whether a non-U.S. corporation is a PFIC, a proportionate share of the income and assets of each corporation in which it owns, directly or indirectly, at least a 25% interest (by value) is taken into account.

A foreign corporation's PFIC status is an annual determination that is based on tests that are factual in nature, and our PFIC status for any year will depend on the composition of our income, fair market value of our assets, and our activities for such year. Based on our non-passive revenue-producing operations for the year ended December 31, 2022, we do not expect to be a PFIC for our 2022 taxable year. Because the PFIC determination is highly fact intensive, there can be no assurance that we were not a PFIC in 2022 and will not be a PFIC in 2023 or any other year. Even if we determine that we are not a PFIC after the close of a taxable year, there can be no assurance that the IRS or a court will agree with our conclusion.

If we were a PFIC for any taxable year during which a U.S. holder held ordinary shares, then unless an election has been made by a U.S. holder to be taxed under one of the alternative regimes discussed below, gain recognized by a U.S. holder on a sale or other disposition (including certain pledges) of our ordinary shares would be allocated ratably over the U.S. holder's holding period for our ordinary shares. The amounts allocated to the taxable year of the sale or other disposition and to any year before we became a PFIC would be taxed as ordinary income. The amount allocated to each other taxable year would be subject to tax at the highest rate in effect for individuals or corporations, as appropriate, for that taxable year, and an interest charge would be imposed on the amount allocated to that taxable year. Similar rules would apply to any distribution with respect to our ordinary shares in excess of 125% of the average of the annual distributions received by a U.S. holder during the preceding three years or such U.S. holder's holding period, whichever is shorter. In addition, non-corporate U.S. holders will not be eligible for reduced rates of taxation on any dividends received from us if we are a PFIC in the taxable year in which such dividends are paid or in the preceding taxable year.

If we are a PFIC for any taxable year during which you hold our ordinary shares and our non-United States subsidiary is also a PFIC (the non-United States subsidiary in such a case, the "lower-tier PFIC"),, a U.S. holder would be treated as owning a proportionate amount (by value) of the shares of the lower-tier PFIC for purposes of the application of these rules and a disposition by us of the shares of the lower-tier PFIC or receipt by us of a distribution from the lower-tier PFIC generally will be treated as a deemed disposition of such shares or the deemed receipt of such distribution by the U.S. holder, subject to taxation under the PFIC rules even though the U.S. holder does not receive any proceeds from those dispositions or distributions. There can be no assurance that a U.S. holder will be able to make a "QEF" election with respect to the lower-tier PFIC. U.S. holders are urged to consult their tax advisors about the application of the PFIC rules to our non-United States subsidiary.

If we are treated as a PFIC for any taxable year during the holding period of a non-electing U.S. holder (i.e., a U.S. holder that does not elect to be taxed under one of the alternative regimes discussed below), we will continue to be treated as a PFIC for all succeeding years during which such non-electing U.S. holder is treated as a direct or indirect holder even if we are not a PFIC for such years. A U.S. holder is encouraged to consult its tax advisor with respect to any available elections that may be applicable in such a situation, including the "deemed sale" election of Section 1298(b)(1) of the Code.

Notwithstanding the default PFIC rules described in the preceding paragraphs, certain elections may be available that would result in alternative tax consequences; i.e., the "qualified electing fund" or "QEF" election and the "mark to market" election. If a U.S. holder makes a timely and valid mark-to-market election, the U.S. holder generally will recognize as ordinary income any excess of the fair market value of our 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 our 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). The U.S. holder's tax basis in our ordinary shares will be adjusted to reflect the income or loss resulting from the mark-to-market election. 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 and any loss in excess of such amount will be treated as capital loss). The mark-to-market election is available only if we are a PFIC and our ordinary shares are "regularly traded" on a "qualified exchange" within the meaning of applicable U.S. Treasury regulations. Our ordinary shares will be treated as "regularly traded" in any calendar year in which more than a de minimis quantity of our ordinary shares are traded on a qualified exchange on at least 15 days during each calendar quarter. Although the IRS has not published any authority identifying specific exchanges that may constitute "qualified exchanges," Treasury Regulations provide that a qualified exchange is (i) a U.S. securities exchange that is registered with the Securities and Exchange Commission, (ii) the U.S. market system established pursuant to Section 11A of the Securities and Exchange Act of 1934, or (iii) a non-U.S. securities exchange that is regulated or supervised by a governmental authority of the country in which the market is located, provided that: (a) such non-U.S. exchange has trading volume, listing, financial disclosure, surveillance, and other requirements designed to prevent fraudulent and manipulative acts and practices, to remove impediments to and perfect the mechanism of a free and open, fair and orderly, market, and to protect investors, and the laws of the country in which such non-U.S. exchange is located and the rules of such non-U.S. exchange ensure that such requirements are actually enforced; and (b) the rules of such non-U.S. exchange effectively promote active trading of listed shares. The Nasdaq Global Market is a qualified exchange for this purpose, but there can be no assurance that the trading in our ordinary shares will be sufficiently regular to qualify our ordinary shares as marketable stock. A mark-to-market election will not apply to ordinary shares held by a U.S. holder for any taxable year during which we are not a PFIC, but will remain in effect with respect to any subsequent taxable year in which we become a PFIC unless our ordinary shares are no longer regularly traded on a qualified exchange or the IRS consents to the revocation of the election. Such election will not apply to any PFIC subsidiary that we own. Each U.S. holder is encouraged to consult its own tax advisor with respect to the availability and tax consequences of a mark-to-market election with respect to our ordinary shares.

Another way in which certain of the adverse consequences of PFIC status can be mitigated is for a U.S. holder to make a QEF election. Generally, a shareholder making the QEF election is required for each taxable year to include in income a pro rata share of our ordinary earnings and net capital gain of the QEF, subject to a separate election to defer payment of taxes, which deferral is subject to an interest charge. An election to treat us as a QEF will not be available if we do not provide the information necessary to make such an election. We are not obligated and do not currently intend to provide the information necessary to make a QEF election and thus it is not expected that a QEF election will be available for U.S. holders of our ordinary shares if we were a PFIC in any prior year, the current year or any future year.

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

If a U.S. holder holds ordinary shares in any year in which we are treated as a PFIC, the U.S. holder will be required to file IRS Form 8621 and may be subject to certain other information reporting requirements.

The U.S. federal income tax rules relating to PFICs are complex. Prospective U.S. holders are urged to consult their own tax advisors with respect to 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 purchase, ownership, and disposition of our ordinary shares in the event we are determined to be a PFIC.

***Medicare Tax on Investment Income***

In addition to the income taxes described above, U.S. holders that are individuals, estates, or trusts and whose income exceeds certain thresholds will be subject to a 3.8% tax on all or a portion of their "net investment income," which generally would include dividends on, and dispositions of, our ordinary shares. U.S. holders should consult their tax advisors with respect to the applicability of the 3.8% Medicare tax to their income and gains, if any, resulting from their investment in our ordinary shares.

***Information Reporting and Backup Withholding***

A U.S. holder may be subject to backup withholding and information reporting requirements with respect to cash distributions and proceeds from a disposition of ordinary shares. In general, backup withholding will apply only if a U.S. holder fails to comply with certain identification procedures. Information reporting and backup withholding will not apply with respect to payments made to certain exempt recipients, such as corporations and tax-exempt organizations. Backup withholding is not an additional tax and may be claimed as a credit against the U.S. federal income tax liability of a U.S. holder, provided that the required information is furnished to the IRS.

 ****

***Tax Reporting***

Certain U.S. holders will be required to file an IRS Form 926 (Return by a U.S. Transferor of Property to a Foreign Corporation) to report a transfer of cash or other property to us. Substantial penalties may be imposed on a U.S. holder that fails to comply with this reporting requirement. Each U.S. holder is urged to consult with its own tax advisor regarding this reporting obligation.

 ****

 ****

***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. For example, certain U.S. holders that own "specified foreign financial assets" with an aggregate value in excess of $50,000 (and in some circumstances, a higher threshold) are generally required to file IRS Form 8938 with respect to such assets with their tax returns. "Specified foreign financial assets" include any financial accounts maintained by foreign financial institutions, as well as any of the following, but only if they are not held in accounts maintained by financial institutions: (i) stocks and securities issued by non-U.S. persons; (ii) financial instruments and contracts held for investment that have non-U.S. issuers or counterparties; and (iii) interests in foreign entities. Failure to file IRS Form 8938 for each applicable taxable year may result in substantial penalties and the statute of limitations on the assessment and collection of U.S. federal income taxes of such U.S. holder for the related taxable year may not close until three years after the date on which the required information is filed. In addition, a U.S. holder should consider the possible obligation to file FinCEN Form 114, Report of Foreign Bank and Financial Accounts, as a result of holding ordinary shares. U.S. holders are urged to consult their tax advisors regarding the application of these and other reporting requirements that may apply to their ownership of ordinary shares.

 ****

***Non-U.S. Holders of Ordinary Shares***

Except as provided below, a non-U.S. holder of ordinary shares generally will not be subject to U.S. income or withholding tax on the payment of dividends on and the proceeds from the disposition of ordinary shares.

A non-U.S. holder may be subject to U.S. federal income tax on dividends received on ordinary shares or upon the receipt of income from the disposition of ordinary shares if: (i) such income is effectively connected with the conduct by the non-U.S. holder of a trade or business in the United States or, in the case of a resident of a country which has an applicable income tax treaty with the United States, such item is attributable to a permanent establishment or a fixed place of business of the non-U.S. holder in the United States; (ii) with respect to a U.S. holder that is an individual, the non-U.S. holder is an individual who is present in the United States for 183 days or more in the taxable year of the sale and certain other conditions are met; or (iii) the non-U.S. holder is subject to tax pursuant to the provisions of the U.S. tax laws applicable to certain former citizens or residents of the United States.

Payments to non-U.S. holders of distributions on, or proceeds from the disposition of, ordinary shares are generally exempt from information reporting and backup withholding. However, a non-U.S. holder may be required, under certain circumstances, to establish that exemption by providing certification of non-U.S. status on an appropriate IRS Form W-8.

&nbsp;&nbsp;&nbsp;&nbsp;**H.** **Documents on Display** 

We are subject to certain information reporting requirements of the Exchange Act, applicable to foreign private issuers and under those requirements will file reports with the SEC. The SEC maintains an internet site at http://www.sec.gov that contains reports, proxy and information statements and other information regarding issuers that file electronically with the SEC. Our filings with the SEC will also be available to the public through the SEC's website at www.sec.gov.

As a foreign private issuer, we are exempt from the rules under the Exchange Act related to the furnishing and content of proxy statements, and our officers, directors and principal shareholders will be exempt from the reporting and short-swing profit recovery provisions contained in Section 16 of the Exchange Act. In addition, we are not required under the Exchange Act to file annual, quarterly 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. However, we will file with the SEC, within 120 days after the end of each fiscal year, or such applicable time as required by the SEC, an annual report on Form 20-F containing financial statements audited by an independent registered public accounting firm, and may submit to the SEC, on a Form 6-K, unaudited quarterly financial information.

| **ITEM 11.** | **QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK** |

---

We are exposed to market risk 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 fluctuations in foreign currency exchange rates and interest rates.

 ****

***Foreign Currency Exchange Risk***

Our functional and reporting currency is the U.S. dollar. Our foreign currency exposures give rise to market risk associated with exchange rate movements of the NIS, mainly against the U.S. dollar and the Euro. A material portion of our expenses consist principally of payments in NIS made to employees, subcontractors and consultants for clinical trials, other research and development activities, and purchase of new equipment. A material portion of our research and development is conducted through collaboration agreements denominated in U.S. dollars, and therefore our net research and development expenses are subject to significant foreign currency risk. If the NIS fluctuates significantly against either the U.S. dollar or the Euro, it may have a negative impact on our results of operations.

To date, we have not entered into any hedging arrangements with respect to foreign currency risk or other derivative financial instruments. In the future, we may enter into currency hedging transactions to decrease the risk of financial exposure from fluctuations in the operating currencies. These measures, however, may not adequately protect us from the material adverse effects of such fluctuations.

***Interest Rate Risk***

At present, our investments consist primarily of cash and cash equivalents in short-term deposits. The primary objective of our investment activities is to preserve our capital to fund our operations. Our investments are exposed to market risk due to fluctuation in interest rates, which may affect our interest income and the fair market value of our investments, if any. We manage this exposure by performing ongoing evaluations of our investments. Due to the short-term maturities, if any, of our investments to date, their carrying value has always approximated their fair value. We believe that our exposure to interest rate risk is not significant and a 1% change in market interest rates would not have a material impact on our assets.

&nbsp;&nbsp;&nbsp;&nbsp;**(a)** **Disclosure Controls and Procedures** 

Our management, with the participation of our Chief Executive Officer and Deputy CEO & Chief Financial Officer, has evaluated the effectiveness of our disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of December 31, 2022, or the Evaluation Date. Based on such evaluation, those officers have concluded that, as of the Evaluation Date, our disclosure controls and procedures are effective in recording, processing, summarizing and reporting, on a timely basis, information required to be included in periodic filings under the Exchange Act and that such information is accumulated and communicated to management, including our principal executive and financial officers, as appropriate to allow timely decisions regarding required disclosure.

&nbsp;&nbsp;&nbsp;&nbsp;**(b)** **Management's Annual Report on Internal Control over Financial Reporting** 

Our management is responsible for establishing and maintaining adequate internal control over our financial reporting. Internal control over financial reporting is defined in Rule 13a-15(f) or 15d-15(f) promulgated under the Exchange Act as a process designed by, or under the supervision of, the company's principal executive and principal financial officers and effected by the company's board of directors, management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles and includes those policies and procedures that:

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

● 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

● 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. Projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Our management assessed the effectiveness of our internal control over financial reporting as of December 31, 2022. In making this assessment, our management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control-Integrated Framework (2013). Based on that assessment, our management concluded that as of December 31, 2022, our internal control over financial reporting was effective.

&nbsp;&nbsp;&nbsp;&nbsp;**(c)** **Attestation Report of the Registered Public Accounting Firm** 

This Annual Report on Form 20-F does not include an attestation report of our independent registered public accounting firm regarding internal control over financial reporting due to an exemption for emerging growth companies provided in the JOBS Act.

&nbsp;&nbsp;&nbsp;&nbsp;**(d)** **Changes in Internal Control over Financial Reporting** 

During the year ended December 31, 2022, there were no changes in our internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

&nbsp;&nbsp;&nbsp;&nbsp;(2) Tax fees for the years ended December 31, 2022 and 2021 were for services related to tax advice, including assistance with tax audit.

***Pre-Approval of Auditors' Compensation***

Our audit committee has a pre-approval policy for the engagement of our independent registered public accounting firm to perform certain audit and non-audit services. Pursuant to this policy, which is designed to assure that such engagements do not impair the independence of our auditors, the audit committee pre-approves annually a catalog of specific audit and non-audit services in the categories of audit services, audit-related services and tax services that may be performed by our independent registered public accounting firm. If a type of service, that is to be provided by our auditors, has not received such general pre-approval, it will require specific pre-approval by our audit committee. The policy prohibits retention of the independent registered public accounting firm to perform the prohibited non-audit functions defined in applicable SEC rules.

---

Under the Companies Law, companies incorporated under the laws of the State of Israel, whose shares are publicly traded, including companies whose shares are listed on the Nasdaq Global Market are considered public companies under Israeli law and are required to comply with various corporate governance requirements under Israeli law relating to such matters as external directors, the audit committee, compensation committee, compensation policy, company's auditors, and an internal auditor. These requirements are in addition to the corporate governance requirements imposed by the Nasdaq Listing Rules, and other applicable provisions of U.S. securities laws to which we are subject as a foreign private issuer due to the listing of our ordinary shares on the Nasdaq Global Market. However, pursuant to regulations promulgated under the Companies Law, companies with shares traded on certain U.S. stock exchanges, including the Nasdaq Global Market, may, subject to certain conditions, "opt out" from the requirement of the Companies Law to appoint external directors and related Companies Law rules concerning the composition of the audit committee and compensation committee of the board of directors (other than the gender diversification rule under the Companies Law which requires the appointment of a director from the other gender if, at the time a director is appointed, all members of the board of directors are of the same gender). In accordance with these regulations, we have elected to "opt out" from such requirements of the Companies Law. For further information, see "Item 6.C. – Board Practices - Board of Directors". Under these regulations, the exemptions from such Companies Law's requirements will continue to be available to us so long as we comply with the following: (i) we do not have a "controlling shareholder" (as such term is defined under the Companies Law), (ii) our shares are traded on certain U.S. stock exchanges, including the Nasdaq Global Market, and (iii) we comply with the director independence requirements and the requirements regarding the composition of the audit committee and the compensation committee under U.S. laws (including applicable Nasdaq rules) applicable to U.S. domestic issuers.

Under the Nasdaq Listing Rules, a foreign private issuer, such as us, may generally follow its home country rules of corporate governance in lieu of the comparable requirements of the Nasdaq Global Market, except for certain matters including (among others) the composition and responsibilities of the audit committee and the independence of its members within the meaning of the rules and regulations of the SEC.

We intend to rely on this "home country practice exemption" with respect to the following Nasdaq Listing Rules:

●  ***Quorum requirements.*** As permitted under the Companies Law pursuant to our articles of association, the quorum required for an ordinary meeting of shareholders will consist of at least two shareholders present in person, by proxy or by other voting instrument in accordance with the Companies Law, who hold at least 20% of the voting power of our shares (and in an adjourned meeting, with some exceptions, any number of participating shareholders), instead of 33<sup>1</sup>/<sub>3</sub>% of the issued share capital required under the Nasdaq Listing Rules.

●  ***Distribution of certain reports to shareholders.*** As opposed to the Nasdaq Listing Rules, which require listed issuers to make its annual reports available to shareholders in one of a number of specific manners, Israeli law does not require that we distribute annual reports, including our financial statements. As such, the generally accepted business practice in Israel is to distribute such reports to shareholders through a public regulated distribution website. In addition to making such reports available on a public regulated distribution website, we plan to make our audited financial statements available to our shareholders at our offices and will only mail such reports to shareholders upon request. As a foreign private issuer, we are generally exempt from the SEC's proxy solicitation rules.

●  ***Shareholder approval.*** We will seek shareholder approval for all corporate actions requiring such approval under the requirements of the Companies Law, rather than seeking approval for corporate actions in accordance with Nasdaq Listing Rule 5635. In particular, under this Nasdaq Listing Rule, shareholder approval is generally required for: (i) an acquisition of shares or assets of another company that involves the issuance of 20% or more of the acquirer's shares or voting rights or if a director, officer or 5% shareholder has greater than a 5% interest in the target company or the consideration to be received; (ii) the issuance of shares leading to a change of control; (iii) adoption or amendment of equity compensation arrangements; and (iv) issuances of 20% or more of the shares or voting rights (including securities convertible into, or exercisable for, equity) of a listed company via a private placement (or via sales by directors, officers or 5% shareholders) if such equity is issued (or sold) at below the greater of the book or market value of shares. By contrast, under the Companies Law, shareholder approval is required (subject to certain limited exceptions) for, among other things: (a) transactions with directors concerning the terms of their service (including indemnification, exemption, and insurance for their service or for any other position that they may hold at a company), for which approvals of the compensation committee, board of directors, and shareholders are all required; (b) extraordinary transactions with controlling shareholders of publicly held companies, which require the special approval described below under "Disclosure of Personal Interests of Controlling Shareholders and Approval of Certain Transactions;" (c) terms of office and employment or other engagement of our controlling shareholder, if any, or such controlling shareholder's relative, which require the special approval described below under "Disclosure of Personal Interests of Controlling Shareholders and Approval of Certain Transactions;" (d) approval of transactions with Company's Chief Executive Officer with respect to his or hers compensation, whether in accordance with the approved compensation policy of the Company or not in accordance with the approved compensation policy of the Company, or transactions with officers of the Company not in accordance with the approved compensation policy; and (e) approval of the compensation policy of the Company for office holders. In addition, under the Companies Law, a merger requires approval of the shareholders of each of the merging companies.

Except as stated above, we intend to comply with the rules generally applicable to U.S. domestic companies listed on the Nasdaq Global Market, subject to certain exemptions the JOBS Act provides to emerging growth companies. We may in the future decide to use other foreign private issuer exemptions with respect to some or all of the other Nasdaq Listing Rules. Following our home country governance practices, as opposed to the requirements that would otherwise apply to a company listed on the Nasdaq Global Market, may provide less protection than is accorded to investors under the Nasdaq Listing Rules applicable to domestic issuers.

**Opinion on the Financial Statements**

**We have audited the accompanying consolidated balance sheets of CollPlant Biotechnologies Ltd. (the "Company") as of December 31, 2022 and 2021, the related consolidated statements of operations, comprehensive loss, shareholders' equity and cash flows for each of the three years in the period ended December 31, 2022, and the related notes (collectively referred to as the "consolidated financial statements"). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2022 and 2021, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2022, in conformity with U.S. generally accepted accounting principles.**

**Basis for Opinion**

**These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.**

**We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting. Accordingly, we express no such opinion.**

**Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.**

**COLLPLANT BIOTECHNOLOGIES LTD.**

**NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS**

(U.S. dollars in thousands, except share and per share amounts)

**NOTE 1 - GENERAL**

CollPlant Biotechnologies Ltd. (the "Company") is a regenerative and aesthetic medicine company focused on 3D bioprinting of tissues and organs and medical aesthetics. The Company's products are based on its rhCollagen (recombinant human collagen) produced with CollPlant's proprietary plant based technology.

The Company operates mainly through CollPlant Ltd., a wholly-owned subsidiary (CollPlant Biotechnologies Ltd. and CollPlant Ltd. will be referred to hereinafter as "the Company" and "CollPlant", respectively). In November 2021 CollPlant Ltd established CollPlant Inc., a wholly owned subsidiary in the United States. As of December 31, 2022, CollPlant Inc has not commenced operation.

**NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS**

(U.S. dollars in thousands, except share and per share amounts)

**NOTE 2 - SIGNIFICANT ACCOUNTING POLICIES**

**a.** **Basis of presentation of the financial statements** 

The accompanying consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States ("GAAP") and include the accounts of Collplant Biotechnologies Ltd. and its wholly-owned subsidiaries.

**b.** **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 assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. The Company's management believes that the estimates, judgment and assumptions used are reasonable based upon information available at the time they are made. Actual results may differ from those estimates.

**c.** **Functional currency** 

The functional currency is the currency that best reflects the economic environment in which the Company and its subsidiaries operates and conducts their transactions. Most of the Company's financing activity, cash flows, costs and expenses are incurred in U.S. dollar. Base on the Company's management assessment the functional currency of the Company is the U.S. dollar.

Transactions and balances that are denominated in currencies other than the U.S. dollar are remeasured into U.S. dollars in accordance with principles set forth in Accounting Standard Codification ("ASC") Topic 830, Foreign Currency Matters ("ASC 830"). In accordance with ASC 830, monetary assets and liabilities denominated in foreign currencies are remeasured into U.S. dollars at the end of each reporting period using the exchange rates in effect at the balance sheet date. Non-monetary assets denominated in foreign currencies are measured using historical exchange rates. Gains and losses resulting from remeasurement are reflected in the statements of comprehensive income (loss) as financial income or expenses, as appropriate.

**NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS**

(U.S. dollars in thousands, except share and per share amounts)

**NOTE 2 - SIGNIFICANT ACCOUNTING POLICIES (continued)**

**d.** **Principles of consolidation** 

The consolidated financial statements include the accounts of the Company and its subsidiaries. All inter-company transactions and balances have been eliminated in consolidation.

**e.** **Segments** 

The Company identifies operating segments in accordance with ASC Topic 280, "Segment Reporting" as components of an entity for which discrete financial information is available and is regularly reviewed by the chief operating decision maker, or decision-making group, in making decisions regarding resource allocation and evaluating financial performance. The Company defines the term "chief operating decision maker" to be its chief executive officer. The Company determined it operates in one operating segment and one reportable segment, as its chief operating decision maker reviews financial information presented only on a consolidated basis for purposes of allocating resources and evaluating financial performance.

**f.** **Cash and cash equivalents** 

The Company considers as cash equivalents all short-term, highly liquid investments, which include short-term bank deposits with original maturities of three months or less from the date of purchase that are not restricted as to withdrawal or use and are readily convertible to known amounts of cash.

**g.** **Short-term bank deposits** 

Short-term bank deposits are deposits with an original maturity of more than three months and less than a year from the date of investment and which do not meet the definition of cash equivalents.

**h.** **Restricted deposits** 

The Company's considers as restricted deposits long term and short term collaterals related to the Company's lease contracts and credit card.

**i.** **Trade receivables** 

Trade receivables are stated net of credit losses allowance. The Company is exposed to credit losses primarily through sales of products. The allowance against gross trade receivables reflects the current expected credit loss inherent in the receivables portfolio determined based on the Company's methodology. The Company's methodology is based on historical experience, customer creditworthiness, current and future economic condition and market condition. Additionally, specific allowance amounts are established to record the appropriate provision for customers that have a higher probability of default. The Company's assessment for credit loss is negligible.

**NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS**

(U.S. dollars in thousands, except share and per share amounts)

**NOTE 2 - SIGNIFICANT ACCOUNTING POLICIES (continued)**

**j.** **Inventories** 

Inventory is measured at the lower of cost and net realizable value.

Inventory costing is based on the moving average cost method. In the case of purchased goods and work in process, costs include raw materials, direct labor, share based compensation and other direct costs and fixed production overheads (based on the normal operating capacity of the production facilities).

Net realizable value is the estimated selling price in the ordinary course of business, less attributable selling expenses.

**k.** **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 and current and non-current operating lease liabilities in the consolidated balance sheets.

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. Lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. 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. The Company also elected the practical expedient to not separate lease and non-lease components for its leases (see also Note 6).

**m.** **Impairment of long-lived assets** 

The Company's long-lived assets are reviewed for impairment in accordance with ASC 360, "Property, Plant and Equipment" ("ASC 360"), whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. Recoverability of an asset to be held and used is measured by a comparison of the carrying amount of an asset to the future undiscounted cash flows expected to be generated by the asset. If such asset is considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the asset exceeds its fair value.

For the three years ended December 31, 2022, the Company did not recognize an impairment loss for its long-lived assets.

**n.** **Intangible assets** 

The Company capitalizes development costs incurred during the application development stage that are related to internal use technology. Under ASC 350-40, internal-use software capitalization begins when the preliminary project stage is complete and ceases at the point in which the project is substantially complete and is ready for its intended purpose.

Cost capitalized to internal use software include sub-contractors services and employee salary expenses.

**NOTE 2 - SIGNIFICANT ACCOUNTING POLICIES (continued)**

**o.** **Share-based compensation** 

The Company accounts for employees' share-based payment awards classified as equity awards using the grant-date fair value. The fair value of each share option award is estimated on the grant date using the Black-Scholes option-pricing model. The Black-Scholes option-pricing model requires the input of highly subjective assumptions, including the fair value of the underlying ordinary shares, the expected term of the share option, the expected volatility of the price of our ordinary shares, risk-free interest rates, and the expected dividend yield of ordinary shares. The assumptions used to determine the fair value of the option awards represent management's best estimates. These estimates involve inherent uncertainties and the application of management's judgment. 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 based on the multiple-option award approach.

The Company elected to account for forfeitures as they occur.

**p.** **Research and development expenses** 

Research and development expenses include costs directly attributable to the conduct of research and development programs, including the cost of 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.

Grants received from Israel Innovation Authority (hereafter - "IIA"), are recognized when the grant becomes receivable, provided there is reasonable assurance that the Company will comply with the conditions attached to the grant and there is reasonable assurance the grant will be received. The grant was deducted from the research and development expenses as the applicable costs are incurred, and presented in research and development expenses, net. See Note 7.

For the years ended December 31, 2022, 2021 and 2020 the Company did not receive any grants.

**q.** **Revenue recognition** 

Revenues are recognized in accordance with ASC 606; revenue from contracts with customers is recognized when control of the promised goods or services is transferred to the customers, in an amount that the Company expects in exchange for those goods or services.

The Company recognizes revenue under the core principle that transfer of control to the Company's customers should be depicted in an amount reflecting the consideration the Company expects to receive in revenue. In order to achieve that core principle, the Company applies the following five-step approach: (1) identify the contract with a customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price to the performance obligations in the contract, and (5) recognize revenue when the performance obligation is satisfied.

(U.S. dollars in thousands, except share and per share amounts)

**NOTE 2 - SIGNIFICANT ACCOUNTING POLICIES (continued)**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) Identify the contract with a customer

A contract is an agreement between two or more parties that creates enforceable rights and obligations. In evaluating the contract, the Company analyzes the customer's intent and ability to pay the amount of promised consideration and considers the probability of collecting substantially all of the consideration.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) Identify the performance obligations in the contract

At a contract's inception, the Company assesses the goods or services promised in a contract with a customer and identifies the performance obligations.

Performance obligations are promised goods or services in a contract to transfer a distinct good or service to the customer.

The Company evaluates whether options granted to a customer to acquire additional goods or services give rise to a performance obligation. If an agreement contains such option, the Company determines that the option is a separate performance obligation only if the option provides a material right to the customer that it would not receive without entering into that agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) Determine the transaction price

The Company estimates the transaction price based on the amount of consideration the Company expects to be received for transferring the promised goods or services in the contract. The consideration may include both fixed consideration and variable consideration. At the inception of each arrangement that includes variable consideration, the Company evaluates the amount of the potential payments and the likelihood that the payments will be received. If it is probable that a significant revenue reversal would not occur, the variable consideration is included in the transaction price.

The transaction price is allocated to each performance obligation on a relative stand-alone selling price basis. In determining the stand-alone selling price the Company considers market conditions as well as entity-specific factors, including those factors contemplated in negotiating the agreements as well as internally developed estimates that include assumptions related to the market opportunity, estimated development costs, probability of success and the time needed to commercialize a product candidate pursuant to the license.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(4) Allocate the transaction price to the performance obligations in the contract

For contracts with more than one performance obligation the Company allocates the transaction price to each separate performance obligation, based on its relative standalone selling price.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(5) Recognize revenue when a performance obligation is satisfied

Revenue is recognized when or as performance obligations are satisfied by transferring control of a promised good or service to a customer. Control either transfers over time or at a point in time, which affects when revenue is recorded.

(U.S. dollars in thousands, except share and per share amounts)

**NOTE 2 - SIGNIFICANT ACCOUNTING POLICIES (continued)**

Up-front payments and fees are recorded as deferred revenue upon receipt or when due until the Company performs its obligations under these arrangements. Amounts expected to be recognized as revenue within the 12 months following the balance sheet date are classified as current portion of deferred revenue in the accompanying consolidated balance sheets. Amounts not expected to be recognized as revenue within the 12 months following the balance sheet date are classified as deferred revenue, net of current portion. Amounts are recorded as accounts receivable when the Company's right to consideration is unconditional.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. Revenues from sale of goods

The goods are products based on the Company's rhCollagen, and include the BioInk product for the development of 3D bioprinting of organs and tissues and the medical aesthetics and products for tendinopathy and wound healing. The Company recognizes revenues from selling goods at a point in time when control over the product is transferred to customers .

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2. Revenues from rendering services

Revenue from rendering of services is recognized over time, during the period the customer simultaneously receives and consumes the benefits provided by the Company's performance. Under the Company's service contracts, the Company has a right to consideration from the customer in an amount that corresponds directly with the value to the customer of the Company's performance completed to date and recognizes revenue in the amount to which the Company has a right to invoice.

The Company charges its customers based on payment terms agreed upon in specific agreements. When payments are made before or after the service is performed, the Company recognizes the resulting contract asset or liability.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3. Revenues from licensing agreement

On February 5, 2021, the Company signed a Development, Exclusivity and Option Products Agreement ("the Development Agreement"), with AbbVie, pursuant to which the Company and AbbVie will collaborate in the development and commercialization of dermal and soft tissue filler products for the medical aesthetics market, using the Company's rhCollagen technology and AbbVie's technology (see also Note 7).

The Company has identified in the Development Agreement the right for the CollPlant technology and right to use any know-how related to CollPlant rhCollagen.

Pursuant to the Development Agreement CollPlant grants AbbVie, its affiliates and third-party transferees a right to use any know-how related to CollPlant rhCollagen that is (a) necessary or useful to exploit an exclusive product and (b) controlled by CollPlant or its affiliates, solely to support the regulatory approval of such exclusive product.

The Company determined that those rights described above are to the use of the IP of CollPlant, therefore represent a right under a license contract. The Company farther identified the license as a performance obligation.

**COLLPLANT BIOTECHNOLOGIES LTD.**

**NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS**

(U.S. dollars in thousands, except share and per share amounts)

**NOTE 2 - SIGNIFICANT ACCOUNTING POLICIES (continued)**

In addition, the Company has identified in the Development Agreement (i) certain development activities, (ii) a right of first negotiation for Option Products, and (iii) an option for future supply agreement. However, neither of the above mentioned is distinct and/or provides a material right to the customer and therefore, do not give rise to a performance obligation.

As such the Company has concluded that the contract includes only one performance obligation, and the transaction price was fully allocated to the license delivery performance obligation.

The transaction price included an up-front paid amount of $14,000 as well as variable considerations contingent upon the Company or AbbVie achieving certain milestones and sales-based royalties ("Variable Consideration"). The Company estimates variable consideration using the most likely method. Amounts included in the transaction price are recognized only when it is probable that a significant reversal of cumulative revenues will not occur.

Since it is not probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the milestone payments is resolved, and since the contract include termination provisions, the Company estimated the transaction price at $14,000 and recognized that amount as revenue once the license was delivered.

For the year ended December 31, 2022 the Company did not reach any millstones and therefore did not recognize revenues relating to the Development Agreement.

Sales-based royalties are not included in the transaction price. Rather, they are recognized as incurred, due to the specific exception of ASC 606 for sales-based royalties in licensing of intellectual properties.

**r.** **Income taxes** 

1) Deferred taxes Income taxes are computed using the asset and liability method. Under the asset and liability method, deferred income tax assets and liabilities are determined based on the differences between the financial reporting and tax bases of assets and liabilities and are measured using the currently enacted tax rates and laws. 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. The Company has provided a full valuation allowance with respect to its deferred tax assets.

2) Uncertainty in income taxes 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 the more likely than not 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.

**NOTE 2 - SIGNIFICANT ACCOUNTING POLICIES (continued)**

**s.** **Income (loss) per share** 

Basic income (loss) per share is computed on the basis of the net income (loss), for the period divided by the weighted average number of ordinary shares and prepaid warrants outstanding during the period. Diluted income (loss) per share is based upon the weighted average number of ordinary shares and of potential ordinary shares outstanding when dilutive. Ordinary share equivalents include outstanding stock options and warrants, which are included under the treasury stock method when dilutive. The calculation of diluted income (loss) per share does not include options and warrants exercisable into 2,558,164, 1,590,346 and 4,008,007 shares for the years ended December 31, 2022, 2021 and 2020, respectively, because the effect would be anti-dilutive.

**t.** **Fair value measurement** 

Fair value is based on the price that would be received from the sale of an asset or that would be paid to transfer a liability in an orderly transaction between market participants at the measurement date. In order to increase consistency and comparability in fair value measurements, the guidance establishes a fair value hierarchy that prioritizes observable and unobservable inputs used to measure fair value into three broad levels, which are described as follows:

Level 1: Quoted prices (unadjusted) in active markets that are accessible at the measurement date for assets or liabilities.

Level 2: Observable prices that are based on inputs not quoted on active markets, but corroborated by market data.

Level 3: Unobservable inputs are used when little or no market data is available.

In determining fair value, the Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible and considers counterparty credit risk in its assessment of fair value. A financial instrument's categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement.

The carrying amount of the cash and cash equivalents, restricted deposits, trade receivable, trade payables, accrued expenses and other liabilities approximates their fair value.

The Company's financial liability at fair value through profit or loss is the anti-dilution derivatives, classified as liabilities, and amounted to $28 as of December 31, 2020. As of December 31, 2021 the assumption of probability for anti dilution event was 0%, hence the financial liability fair value was $0.

As of December 31, 2022 and 2021, the company has no financial instruments measured at fair value.

**u.** **Newly issued and recently adopted accounting pronouncements:** 

In August 2020, the FASB issued ASU No. 2020-06, Accounting for Convertible Instruments and Contracts in an Entity's Own Equity (ASU 2020-06), which simplifies the accounting for certain financial instruments with characteristics of liabilities and equity, including convertible instruments and contracts in an entity's own equity. Among other changes, ASU 2020-06 removes from GAAP the liability and equity separation model for convertible instruments with a cash conversion feature and a beneficial conversion feature, and as a result, after adoption, entities will no longer separately present in equity an embedded conversion feature for such debt. Similarly, the embedded conversion feature will no longer be amortized into income as interest expense over the life of the instrument. Instead, entities will account for a convertible debt instrument wholly as debt unless (1) a convertible instrument contains features that require bifurcation as a derivative under ASC Topic 815, Derivatives and Hedging, or (2) a convertible debt instrument was issued at a substantial premium. Additionally, ASU 2020-06 requires the application of the if-converted method to calculate the impact of convertible instruments on diluted earnings per share (EPS). ASU 2020-06 is effective for fiscal years beginning after December 15, 2021, with early adoption permitted for fiscal years beginning after December 15, 2020. The adoption of this ASU did not have a material impact on the financial statements.

**Newly issued and not yet adopted accounting pronouncements:**

The Company has reviewed recent accounting pronouncements and concluded that they are either not applicable to its business or that no material effect is expected on the consolidated financial statements as a result of their future adoption

**NOTE 9 - INCOME TAX**

The Company and its Israeli subsidiary are taxed under Israel tax laws:

**A.** **Tax rates** 

After the Company consummates its Net Operating Losses, the corporate tax rate applicable for the years 2020-2022, is 23%.

**B.** **Tax assessments** 

The Company and its subsidiary have tax assessments that are considered to be final through tax year 2017.

**C.** **Losses for tax purposes carried forward to future years** 

As of December 31, 2022, CollPlant Biotechnologies Ltd. and CollPlant Ltd had approximately $21,075, and $66,339, respectively, of net carried forward tax losses which are available to be offset against future taxable income in future with no limited period of use.

| Net deferred tax assets | - | - |

---

Realization of deferred tax assets is contingent upon sufficient future taxable income during the period that deductible temporary differences and carried forward losses are expected to be available to be offset against taxable income. As the achievement of required future taxable income is not likely, the Company recorded a full valuation allowance.

**E.** **Reconciliation of theoretical tax expenses to actual expenses** 

The primary difference between the statutory tax rate of the Company and the effective rate results virtually from the changes in valuation allowance in respect of carried forward tax losses for tax purposes and research and development expenses due to the uncertainty of the realization of such tax benefits.

## Exhibit 2.1

**Exhibit 2.1**

**DESCRIPTION OF SECURITIES**

**REGISTERED UNDER SECTION 12 OF THE EXCHANGE ACT** 

**General**

The authorized and registered share capital of CollPlant Biotechnologies Ltd. (the "Company") is NIS 45,000,000 divided into 30,000,000 ordinary shares, nominal (par) value NIS 1.50 each.

**The Nasdaq Global Market** 

Our ordinary shares are listed on The Nasdaq Capital Market under the symbol "CLGN".

**Memorandum and Articles of Association**

**Articles of Association**

The following are summaries of material provisions of our articles of association and the Companies Law insofar as they relate to the material terms of our ordinary shares.

***Purposes and Objects of the Company***

 ****

Our purpose as set forth in our articles of association is to engage in any lawful activity.

***Registration Number***

 ****

Our registration number with the Israeli Registrar of Companies is 52-0039785.

**Voting Rights and Conversion**

All ordinary shares 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 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 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 Articles, our board of directors must consist of not less than three but no more than twelve directors, which includes two external directors, as may be required under the Companies Law. Pursuant to our Articles, 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 Articles allow our board of directors to appoint, with immediate effect or for a future date, additional director(s) who will serve until the Company's next annual general meeting, provided that the total number of directors that shall serve will not exceed the maximum number of directors permitted under our Articles.

**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 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 two most recent fiscal 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 or 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 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.

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 the regulations thereof require that a notice of any annual general meeting or extraordinary general meeting be provided to shareholders at least 21 days or 14 days, as applicable, prior to the meeting and if the agenda of the meeting includes, for example, 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.

One or more shareholders holding at least 1% of the voting rights in the general meeting are entitled to request the company's board of directors to include a proposal on the agenda of a general meeting, provided that the proposal is appropriate to be discussed at a general meeting. Regulations promulgated under the Companies Law provide that such a request should be provided between three to seven days following the notice on the convening of the general meeting, depending on the items on the agenda of such meeting.

All shareholder decisions are to be taken by votes in a shareholders' meeting. Under the Companies Law and our 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 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 20% 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 Articles provide that all resolutions of our shareholders require a simple majority vote, unless otherwise required by the Companies Law or by our Articles. Under the Companies Law, the primary types of engagements or transactions that require approval of our shareholders by a special majority include the following: (i) the approval of an extraordinary transaction with a controlling shareholder or the approval of the terms of employment or other engagement of a controlling shareholder of the company or such controlling shareholder's relative (even if not extraordinary), each of which requires the approval described under "Directors, Senior Management and Employees—Board Practices—Approval of Related Party Transactions Under Israeli Law—Disclosure of Personal Interests of Controlling Shareholders and Approval of Certain Transactions" in our most recent Annual Report on Form 20-F; (ii) the approval of our compensation policy for directors and officers, or the approval of compensation terms to a director or officer which deviate from the terms of the compensation policy, which requires the approval described under "Directors, Senior Management and Employees—Board Practices—Committees of the Board of Directors—Compensation Committee", which we refer to as the Special Majority for Compensation; (iii) the approval of the terms of employment of our CEO, which requires the approval of our shareholders by a Special Majority for Compensation; and (iv) the appointment of our external directors, to the extent that such external directors shall serve on our board of directors, which requires the approval of a majority vote of the shares present and voting at a meeting of shareholders, provided that either: (a) such majority includes at least a majority of the shares held by all shareholders who are not controlling shareholders of the company or have a personal interest in the approval of the item, other than a personal interest that is not as a result of relations with the controlling shareholder participating in the voting; or (b) the total number of shares out of the shareholders detailed in section (a) who vote against the arrangement does not exceed 2% of the company's aggregate voting rights.

 ****

***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. 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 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 articles of association.

**Registration Rights**

Concurrently with the execution of the convertible loan agreements entered into in 2019 with Ami Sagy and certain U.S. Investors, or the 2019 Financing, we entered into Registration Rights Agreements with each of Ami Sagi and the U.S. Investors. Pursuant to the Registration Rights Agreements, we granted one demand registration right to each of Mr. Sagi and the U.S. Investors, which expired in October 2021. In addition, we granted to each of Mr. Sagi and the U.S. Investors F-3 shelf registration rights pursuant to which Mr. Sagi and the U.S. Investors can demand the filing of a shelf registration statement or a public offering under such shelf registration statement, but not more than twice during any 12-month period. We also granted to Mr. Sagi and the U.S. Investors certain piggyback registration rights. All registration rights granted relate to ordinary shares held by Mr. Sagi and the U.S. Investors as well as the ordinary shares to be issued upon exercise of any warrants issued to Mr. Sagi and the U.S. Investors in the 2019 Financing.

As part of the Registration Rights Agreements, we granted customary indemnification rights pursuant to which we undertook to indemnify Mr. Sagi and the U.S. Investors, as the case may be, from and against all Losses (as such term is defined in the Registration Rights Agreements) arising out of or relating to any untrue or alleged untrue statement or omission or alleged omission of a material fact contained in a registration statement and violations of securities laws in connection with the Registration Rights Agreements. Moreover, Mr. Sagi and the U.S. Investors undertook to indemnify us, severally and not jointly, from and against all Losses arising out of or relating to any untrue or alleged untrue statement of a material fact or omission or alleged omission of a material fact contained in any registration statement, but only to the extent that such untrue statement or omission is contained in any information furnished in writing by Mr. Sagi or the U.S. Investors, as the case may be.

We further undertook to bear all fees and expenses incident to the performance of or compliance with the Registration Rights Agreements, whether or not any registerable securities are sold pursuant to a registration statement. This will include all registration and filing fees, printing expenses, communication and delivery expenses, fees and disbursements of counsel for the Company, Securities Act liability insurance (should we desire such insurance), and the fees and expenses of all other persons retained by us in connection with the consummation of the Registration Rights Agreements.

**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 (i) 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 (ii) 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.

Under the Companies Regulations (Relief for Public Companies whose Shared are Traded on Exchanges outside of Israel), the above requirements for a special tender offer do not apply in instances whereby according to the laws of the foreign jurisdiction there are limitations regarding the acquisition of a controlling interest in the company of any specified portion or the acquisition of a controlling interest of any specified portion necessitates an offer by the potential acquirer of a controlling interest to acquire shares from amongst the publicly traded shares.

 ****

***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.

The board of directors of a merging company is required pursuant to the Companies Law to discuss and determine whether, in its opinion, there exists a reasonable concern that, as a result of a proposed merger, the surviving company will not be able to satisfy its obligations towards its creditors, taking into account the financial condition of the merging companies. If the board of directors has determined that such a concern exists, it may not approve a proposed merger. Following the approval of the board of directors of each of the merging companies, the boards of directors must jointly prepare a merger proposal for submission to the Israeli Registrar of Companies.

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.

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.

**Borrowing Powers**

Pursuant to the Companies Law and our articles of association, our board of directors may exercise all powers and take all actions that are not required under law or under our articles of association to be exercised or taken by our shareholders, including the power to borrow money for company purposes.

**Changes in Capital**

Our 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, certain 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.

**Debt Securities**

We do not have any debt securities that are registered under Section 12 of the Securities Act.

**Warrants and Rights**

We do not have any warrants or rights that are registered under Section 12 of the Securities Act.

**Other Securities**

We do not have any other securities that are registered under Section 12 of the Securities Act.
