Questions and Answers About These Proxy Materials and Voting

Why did I receive the Notice of Internet Availability of Proxy Materials instead of a full set of proxy materials?

In accordance with the rules and regulations adopted by the U.S. Securities and Exchange Commission (SEC), we have elected to provide access to our proxy materials over the Internet instead of mailing a printed copy of our proxy materials to each stockholder. Accordingly, we sent a Proxy Availability Notice on or about April 12, 2022 to most stockholders of record entitled to vote at the Annual Meeting. Stockholders may access the proxy materials on a website referred to in the Proxy Availability Notice commencing on or about April 12, 2022 or may request a printed set of the proxy materials be sent to them by following the instructions in the Proxy Availability Notice.

Why did I receive a full set of proxy materials and the Proxy Availability Notice?

We are providing paper copies of the proxy materials to stockholders who have previously requested to receive them in paper form or for whom an election to receive proxy materials electronically by email or over the Internet are not on file. If you would like to reduce the environmental impact and the costs incurred by us in mailing proxy materials, you may elect to receive all future proxy materials electronically by email or over the Internet. To sign up for electronic delivery, please follow the instructions provided with your proxy materials and on your proxy card or voting instruction card for using the Internet and, when prompted, indicate that you agree to receive or access future stockholder communications electronically. Alternatively, you can go to www.proxyvote.com and enroll for online delivery of Annual Meeting and proxy materials.

What does it mean if I receive more than one Proxy Availability Notice?

If you receive more than one Proxy Availability Notice, your shares may be registered in more than one name or in different accounts. Please follow the voting instructions on each Proxy Availability Notice to ensure that all of your shares are voted. All of your shares may be voted at www.proxyvote.com regardless of which account they are registered or held in.

How do I attend the Annual Meeting?

You will not be able to attend the Annual Meeting in person at a physical location because it is being held in a virtual only format due to the COVID-19 pandemic. However, the Annual Meeting has been designed to provide stockholders comparable rights and opportunities to participate as they would have at an in-person meeting, and stockholders of record as of the close of business on March 28, 2022 will be able to participate, vote their shares and ask questions during the meeting by audio webcast. To be admitted to the virtual-only Annual Meeting, you should visit www.virtualshareholdermeeting.com/ASMB2022 and enter the 16-digit control number found on your Proxy Availability Notice.

Additional details on attending and participating in the virtual-only Annual Meeting:

Whether or not you attend the Annual Meeting, we urge you to vote and submit your proxy in advance of the meeting by one of the methods described in this proxy statement.

Who can vote at the Annual Meeting?

Only stockholders of record at the close of business on March 28, 2022 will be entitled to vote at the Annual Meeting. On the record date, there were 48,120,437 shares of common stock outstanding and entitled to vote.

Stockholder of Record:  Shares Registered in Your Name

If on March 28, 2022, your shares were registered directly in your name with our transfer agent, American Stock Transfer & Trust Company, LLC, then you are a stockholder of record. As a stockholder of record, you may vote while attending the meeting or by proxy. Whether or not you plan to attend the meeting, we urge you to fill out and return your proxy card or vote by proxy over the telephone or Internet as instructed below to ensure your vote is counted.

Beneficial Owner:  Shares Registered in the Name of a Broker or Bank

If on March 28, 2022, your shares were held not in your name, but rather in an account at a broker, bank or other similar organization, then you are the beneficial owner of shares held in “street name” and the Proxy Availability Notice is being forwarded to you by that organization. The organization holding your account is considered to be the stockholder of record for purposes of voting at the Annual Meeting. As a beneficial owner, you have the right to direct your broker or other agent regarding how to vote the shares in your account and should follow the instructions provided by your broker, bank or other agent to vote your shares. You are also invited to attend the Annual Meeting.

What am I voting on?

There are six matters scheduled for a vote:

What if another matter is properly brought before the meeting?

The Board knows of no other matters that will be presented for consideration at the Annual Meeting. If any other matters are properly brought before the meeting, it is the intention of the persons named in the accompanying proxy to vote on those matters in accordance with their best judgment.

5

---

 

How do I vote?

For each of the matters, including each of our nominees to the Board, to be voted on, you may vote “FOR” or “AGAINST,” or you may abstain from voting.

The procedures for voting depend upon whether your shares are registered in your name or are held by a bank, broker or other nominee:

Stockholder of Record: Shares Registered in Your Name

If you are a stockholder of record, you may vote at the Annual Meeting, vote by proxy over the Internet, vote by proxy over the telephone or vote by proxy using a proxy card that we have provided or will provide upon request. Whether or not you plan to attend the meeting, we urge you to vote by proxy to ensure your vote is counted. You may still attend and vote at the meeting even if you have already voted by proxy.

Beneficial Owner: Shares Registered in the Name of Broker or Bank

If you are a beneficial owner of shares registered in the name of your broker, bank, or other nominee, you should have received a Proxy Availability Notice containing a voting instruction form from that organization rather than from us. In order to provide voting instructions to the holder of record of your shares, please refer to the materials forwarded by your broker, bank, or other nominee.

 

6

---

 

 

How many votes do I have?

You have one vote for each share of common stock you owned as of March 28, 2022 for each matter that is voted upon at the Annual Meeting.

Who is paying for this proxy solicitation?

We will pay for the entire cost of soliciting proxies. In addition to these proxy materials, our directors and employees may also solicit proxies in person, by telephone or by other means of communication. Directors and employees will not be paid any additional compensation for soliciting proxies. We may also reimburse brokerage firms, banks and other nominees for their reasonable out‑of‑pocket expenses for forwarding proxy materials to beneficial owners and seeking instruction with respect thereto.

Can I vote my shares by filling out and returning the Proxy Availability Notice?

No. The Proxy Availability Notice does, however, provide instructions on how to vote by Internet, mail (by requesting a paper proxy card or voting instruction card), and during the Annual Meeting.

If you receive a proxy statement and a paper proxy card together with the Proxy Availability Notice, the paper proxy card may be used to vote your shares.

Can I change my vote or revoke my proxy after submitting my proxy?

Stockholder of Record: Shares Registered in Your Name

Yes. You can change your vote or revoke your proxy at any time before the deadline to vote. If you are the record holder of your shares, you may change your vote or revoke your proxy in any one of the following ways:

Your most recent vote (prior to the deadline) by Internet, telephone or proxy card or vote at the Annual Meeting will be the one that is counted.

Beneficial Owner: Shares Registered in the Name of Broker, Bank

Yes. You can change your vote or revoke your voting instruction form at any time before the deadline to vote. If your shares are held by your broker or bank as a nominee or agent, you should follow the instructions provided by your broker, bank or other nominee. Note that you may also revoke your proxy in any one of the following ways:

Your most current vote (prior to the deadline) by voting instruction form, telephone or Internet proxy or vote at the Annual Meeting will be the one that is counted.

What are “broker non‑votes”?

Broker non‑votes occur when a beneficial owner of shares held in “street name” does not give voting instructions to the broker, bank or other nominee holding the shares as to how to vote on matters deemed “non‑routine.” Generally, if shares are held in street name, the beneficial owner of the shares is entitled to give voting instructions to the broker, bank or other nominee holding the shares. If the beneficial owner does not provide voting instructions, the broker, bank or other nominee can still vote the shares with respect to matters that are considered to be “routine,” but not with respect to “non‑routine” matters.

7

---

 

The only “routine” matters on the agenda for the Annual Meeting is Proposal No. 3—Ratification of the Selection of the Independent Registered Public Accounting Firm and Proposal No. 5—Approval of an Amendment and Restatement of Fifth Amended and Restated Certificate of Incorporation. Accordingly, the “non‑routine” matters on the agenda for the Annual Meeting are Proposal No. 1—Election of Directors, Proposal No. 2—Advisory Vote to Approve Our Named Executive Officers’ Compensation, Proposal No. 4—Approval of an Amendment to the Assembly Biosciences, Inc. 2018 Stock Incentive Plan and Proposal No 6—Approval of a Stock Option Exchange Program for Non-Executive Employees. Therefore, it is critical that you indicate your vote on these proposals if you want your vote to be counted.

How are votes counted?

Votes will be counted by the inspector of elections appointed for the meeting.

With respect to the election of directors, you may vote “FOR” or “AGAINST” each of the nominees, or you may abstain from voting for one or more nominees. Neither abstentions nor broker non-votes will have any effect on the election of the nominees, but abstentions and broker non-votes will be counted to determine whether a quorum is present at the Annual Meeting.

With respect to the other proposals, you may vote “FOR” or “AGAINST” or you may abstain from voting. Neither abstentions nor broker non-votes will have any effect on the votes Proposal No. 2, Proposal No. 3, Proposal No. 4 and Proposal No. 6, but abstentions and broker non-votes will be counted to determine whether a quorum is present at the Annual Meeting.

What if I return a proxy card or otherwise vote but do not make specific choices?

If you return a signed and dated proxy card or otherwise vote without marking voting selections, your shares will be voted:

What is the quorum requirement?

A quorum of stockholders is necessary to hold a valid meeting. A quorum will be present if stockholders holding a majority of the outstanding shares entitled to vote as of the Record Date are present at the virtual Annual Meeting or represented by proxy. On the record date, there were 48,120,437 shares of common stock outstanding and entitled to vote. As a result, the holders of 24,060,219 shares must be present in person or represented by proxy at the Annual Meeting for there to be a quorum.

8

---

 

Your shares will be counted toward a quorum only if you submit a valid proxy (or one is submitted on your behalf by your broker, bank or other nominee) by May 24, 2022 or if you vote at the Annual Meeting. Abstentions and broker non‑votes will be counted toward the quorum requirement. If there is no quorum, the holders of a majority of shares present at the Annual Meeting or represented by proxy may adjourn the Annual Meeting to another date.

Once a share is represented for any purpose at the Annual Meeting, it is deemed present for quorum purposes for the remainder of the meeting and any adjournment thereof unless a new record date is set for the adjournment.

How many votes are needed to approve each proposal?

Assuming the presence of a quorum at the Annual Meeting, the following sets forth the votes necessary for each of the proposals being submitted to the stockholders:

 

 

Election of Directors

Directors will be elected by the affirmative vote of the majority of the votes cast (meaning the number of shares voted “FOR” a nominee must exceed the number of shares voted “AGAINST” that nominee). If any nominee for director receives a greater number of votes “AGAINST” his or her election than votes “FOR” such election, our Corporate Governance Guidelines require that person to promptly tender his or her written resignation to the Chair of the Board within five days following the certification of the vote. Abstentions and broker non-votes are not considered votes cast for the election of directors and will have no effect on the election of nominees.

Amendment and Restatement of Our Certificate of Incorporation

Adoption of Proposal No. 5 requires the affirmative vote of a majority of the outstanding shares. Abstentions and broker non-votes, if any, will have the same effect as a vote “AGAINST” Proposal No. 5.

Other Proposals

Adoption of Proposal No. 2, Proposal No. 3, Proposal No. 4 and Proposal No. 6 requires the affirmative vote of the majority of votes cast. Abstentions and broker non-votes are not considered votes cast and will have no effect on the vote for these proposals.

How can I find out the results of the voting at the Annual Meeting?

Preliminary voting results will be announced at the Annual Meeting. In addition, final voting results will be reported in a Current Report on Form 8‑K that we expect to file within four business days after the Annual Meeting. If final voting results are not available to us in time to file a Form 8‑K within four business days after the Annual Meeting, we intend to file a Form 8‑K to report preliminary results and, within four business days after the final results are known to us, file an additional Form 8‑K to report the final results.

Proposal No. 1: Election of Directors

General

Our Amended and Restated Bylaws provide that the number of our directors is to be within a range of three to ten, with the exact number set by the Board. The number of directors currently comprising the full Board is nine, but the Board expects to reduce the number of directors to eight immediately following the Annual Meeting.

Our Board currently consists of nine directors. One of our current directors, Myron Z. Holubiak, will not stand for re-election and will retire at the end of his current term. There are eight nominees for election to the Board this year. Each director to be elected and qualified will hold office until the next annual meeting of the stockholders and until his or her successor is duly elected and qualified, or, if sooner, until the director’s death, resignation or removal. Each of the nominees listed below is currently a director. Other than Sir Michael Houghton, Ph.D., who the Board appointed as a director in July 2021, each of the director nominees was previously elected by the stockholders. Directors are elected by a majority of the votes cast in the election of such director, requiring that the number of votes cast “for” a director nominee exceed the number of votes cast “against” that director nominee.

Nominees for Director

The Nominating and Governance Committee has recommended, and the Board has approved, the nomination of each of William R. Ringo, Jr., Anthony E. Altig, Gina Consylman, Richard D. DiMarchi, Ph.D., Sir Michael Houghton, Ph.D., Lisa R. Johnson-Pratt, M.D., Susan Mahony, Ph.D. and John G. McHutchison, A.O., M.D. to serve as a director of our Company. The Board has determined that all of these nominees for director, except for Dr. McHutchison, are independent as determined in accordance with the rules of the Nasdaq Stock Market. There are no family relationships among any of our nominees for director or executive officers. The respective names, ages, lengths of service on our Board and brief biographical summaries of our nominees for director are as follows. For more information regarding the experience, qualifications, attributes and skills of the director nominees, see the matrix on page 19.

Required Vote

Assuming a quorum is present, directors will be elected by the affirmative vote of the majority of the votes cast (meaning the number of shares voted “FOR” a nominee must exceed the number of shares voted “AGAINST” that nominee). All elected nominees will serve until the 2023 Annual Meeting of Stockholders and until their successors have been duly elected and qualified or, if sooner, until the director’s death, resignation or removal. If any current director receives a greater number of votes “AGAINST” his or her election than votes “FOR” such election, our Corporate Governance Guidelines require that person to promptly tender his or her written resignation to the Chairman of the Board within five days following the certification of the vote. Abstentions and broker non-votes are not considered votes cast for the election of directors and will have no effect on the election of nominees.

Recommendation of the Board of Directors

THE BOARD OF DIRECTORS RECOMMENDS A VOTE “FOR” THE ELECTION OF EACH NAMED NOMINEE FOR DIRECTOR.

The Board of Directors and Corporate Governance

This section describes key corporate governance guidelines and practices that we have adopted. Complete copies of the charters of our committees of the Board and our Corporate Governance Guidelines, Code of Conduct and Code of Ethics described below may be found in the Investors section of our website at investor.asssemblybio.com. Alternatively, you can request a copy of any of these documents free of charge by writing to Assembly Biosciences, Inc., attn: Corporate Secretary, 331 Oyster Point Blvd., Fourth Floor, South San Francisco, California 94080. Information on our website is not incorporated by reference into this proxy statement.

Meetings of the Board

Our Company is managed under the general oversight of the Board as provided by the laws of Delaware and our Amended and Restated Bylaws. During the year ended December 31, 2021, the Board held five meetings and acted by unanimous written consent six times. Our independent directors met in executive sessions at which only independent directors were present at the end Board meetings twice in 2021.

The Board has adopted a formal policy that a Board meeting be held on the same date as the annual stockholders meeting and all directors of the Company are encouraged to attend our annual meetings of stockholders. Every 2022 director nominee that served as a director or was a director nominee at the time of the 2021 Annual Meeting was in attendance. Dr. Houghton was neither a nominee for election nor a member of our Board at the time of the 2021 Annual Meeting.

Board Composition

Our Nominating and Governance Committee aims to assemble a Board that brings together a variety of perspectives and skills derived from high quality business and professional experience. Directors must possess high ethical standards, integrity and strong values and be committed to representing the best interests of our stockholders. The Board is composed of individuals that enhance the gender, age and ethnic diversity of the Board.

In fulfilling its responsibilities to select and recommend director nominees to serve on our Board, our Nominating and Governance Committee annually evaluates our incumbent Board members and other candidates, if any, against the following criteria in determining whether to recommend these directors for nomination:

Our Corporate Governance Guidelines provide that the Nominating and Governance Committee must be satisfied that each recommended nominee to the Board meets the following minimum qualifications:

18

---

 

Other than the foregoing, there are no stated minimum criteria for director nominees, although our Nominating and Governance Committee also may consider such other factors as it may deem, from time to time, to be in the best interests of our Company and our stockholders.

We seek a variety of types and degrees of knowledge, skills and experiences among our Board members. The following matrix provides information regarding our Board nominees, including select knowledge, skills, experiences and attributes possessed by our members that the Board believes are relevant to our business. The matrix is not intended to encompass all of the knowledge, skills, experiences or attributes of the nominees, and the fact that a particular knowledge, skill, experience or attribute is not listed does not mean that a nominee does not possess it. In addition, the absence of a particular knowledge, skill, experience or attribute does not mean that that particular nominee is unable to contribute to decision-making in that area.

 

 

Independence of Directors

Our Board assesses the independence of each of our directors under the Nasdaq Stock Market Rules (the Nasdaq listing rules), because our common stock is listed on The Nasdaq Global Select Market. Using the test provided in Rule 5605(a)(2) of the Nasdaq listing rules, the Board has determined that, except for John G. McHutchison, A.O., M.D., our Chief Executive Officer and President, all director nominees (William R. Ringo, Jr., Anthony E. Altig, Gina Consylman, Richard D. DiMarchi, Ph.D., Sir Michael Hougton, Ph.D., Lisa R. Johnson-Pratt, M.D. and Susan

19

---

 

Mahony, Ph.D.) are independent. As part of this determination of independence, our Board considered the relationships that each non-employee director or director nominee has with us and all other facts and circumstances that the Board deemed relevant in determining independence, including the beneficial ownership of our capital stock by such individuals and the association of certain of our directors with third parties, including Indiana University, from whom we license certain intellectual property. After considering these factors, our Board has affirmatively determined that none Mr. Ringo, Mr. Altig, Ms. Consylman, Dr. DiMarchi, Dr. Houghton, Dr. Johnson-Pratt and Dr. Mahony has a relationship with us that would interfere with the exercise of independent judgment in carrying out his or her responsibilities as a director. Our Board also affirmatively determined that Myron Z. Holubiak, who is not standing for re-election to the Board does not have any relationships that would interfere with the exercise of independent judgment in carrying out his responsibilities and is independent.

Board Leadership Structure

Our Board does not have a specific policy regarding the separation of the roles of the Chair of the Board and the Chief Executive Officer and believes it is in the best interests of our Company and our stockholders to be able to exercise discretion in combining or separating these positions as we deem appropriate considering prevailing circumstances. The roles are currently separated, with Mr. Ringo serving as independent Chair. The Board believes that this structure currently best serves the interests of our stockholders because it allows our Chief Executive Officer to focus primarily on our business strategy and operations and most effectively leverages the experience of the Chair. It also enhances the Board’s independent oversight of our senior management team and enables better communication and relations between the Board, the Chief Executive Officer and other members of our senior management team. In that regard, our independent Chair presides at Board meetings and the executive sessions of the non-management and independent directors of the Board. Our approach provides flexibility and allows our Board to modify our leadership structure in the future as appropriate. We believe that we, like many U.S. companies, are well served by this flexible leadership structure.

Risk Oversight

The Board is actively involved in the oversight of risks that could affect us. This oversight is conducted primarily through committees of the Board, particularly the Audit Committee, the Compensation Committee and the Nominating and Governance Committee, but the full Board has retained responsibility for general oversight of risks. The Board satisfies this responsibility through regular reports by each committee chair regarding the committee’s considerations and actions, as well as through regular reports directly from officers responsible for oversight of particular risks.

The Audit Committee is responsible for information security, with a particular focus on cybersecurity. Management provides regular briefings to the Audit Committee if there are any information security breaches. In recent years, we have implemented a variety of initiatives, including enhancement of our email security, evaluation of data protection capabilities of our information technology systems and implementation of a new cybersecurity incident response policy. In addition, we have also implemented a cybersecurity awareness initiative to enable our employees to identify and mitigate information security risks. The initiative is comprised of employee trainings on phishing and other malicious attacks, smart habit creation and best practices regarding file sharing, host security and email security, and we have incorporated cybersecurity training into our employee onboarding process to ensure that all new employees have the necessary skills to identify and mitigate information security risks. In addition, we recently purchased cybersecurity insurance that would defray the costs of an information security breach. We have not experienced any material information security breaches since August 2018, when our email system was hacked. We became aware of the breach and closed access prior to incurring any expenses related to the attack.

Board Committees

The Board has four standing committees. Each committee operates under a charter that has been adopted by the Board, which can be found in the Corporate Governance section of the Investors section of our website at www.assemblybio.com. Information on our website is not incorporated by reference into this proxy statement. Each of the committees has authority to engage legal counsel or other experts or consultants as it deems appropriate to carry out its responsibilities. The table below sets forth the current membership of each of the standing committees and the number of meetings each committee held in 2021. All directors attended 75% or more of the aggregate number of meetings of the Board and meetings of the committees on which he or she served during the period for

which he or she was a director or committee member, as applicable, in 2021. The Board expects to review 2022 committee assignments at its meeting immediately following the Annual Meeting, including, due to Mr. Holubiak’s retirement, appointing (1) a director that meets the Nasdaq requirements to serve as the third member of both the Compensation Committee and the Nominating and Governance Committee and (2) a new Chair of the Compensation Committee at the Board meeting immediately following the Annual Meeting.

 

Audit Committee

The Audit Committee oversees our accounting and financial reporting processes, the audit process, our process for monitoring compliance with laws, regulations and our Code of Conduct and Code of Ethics, and the quality and integrity of our consolidated financial statements and reports. In addition, the Audit Committee oversees the qualification, selection, independence and performance of our independent registered public accounting firm and recommends to the Board the appointment of our independent registered public accounting firm. Our Audit Committee is also responsible for reviewing and approving all related person transactions, including transactions with executive officers and directors, for potential conflicts of interests.

At the direction of the Nominating and Governance Committee, the Audit Committee conducts an annual performance evaluation of the Audit Committee and reports to the Board on the results of such evaluation.

The charter for our Audit Committee requires that the Audit Committee have at least three independent directors.  Our Audit Committee currently consists of Mr. Altig (Chair), Ms. Consylman and Mr. Ringo. The Board annually reviews the Nasdaq listing rules’ definition of independence for Audit Committee members and has determined that Mr. Altig, Ms. Consylman and Mr. Ringo are each independent under the Nasdaq listing rules for audit committee membership and within the meaning of Section 10A-3(b)(1) of the Exchange Act.

The Board has also determined that Mr. Altig and Ms. Consylman each qualify as an “audit committee financial expert” as that term is defined in Item 407(d) of Regulation S‑K promulgated by the SEC. In making that determination, the Board relied on the past experience of Mr. Altig and Ms. Consylman. The Board made a qualitative assessment of Mr. Altig’s level of knowledge and experience based on several factors, including his experience as the chief financial officer of several public companies and having been a certified public accountant. The Board made a qualitative assessment of Ms. Consylman’s level of knowledge and experience based on a number of factors, including her current role as Chief Financial Officer of Vedere Bio II, her past roles as Chief Financial Officer of bluebird bio, bluebird bio’s Severe Genetic Disease business and Ironwood Pharmaceuticals and the series of accounting and finance roles of increasing responsibility at Ironwood Pharmaceuticals, Analogic, Biogen and Varian Semiconductor Equipment Associates, her past role as the audit committee chair at Verastem, Inc. and her experience as a certified public accountant at Ernst & Young LLP.

Compensation Committee

The charter for our Compensation Committee requires the committee to have not less than three independent members, subject to the Nasdaq listing rules. Our Compensation Committee currently consists of Mr. Holubiak (Chair), Dr. Mahony and Mr. Ringo. Our Board has determined that Mr. Holubiak, Dr. Mahony and Mr. Ringo are each independent under the Nasdaq listing rules for compensation committee membership and that each is a “non‑employee director” as defined in Rule 16b‑3 promulgated under the Exchange Act. Due to Mr. Holubiak’s retirement from the Board as of the Annual Meeting, the Board will appoint both (1) a director that meets the Nasdaq requirements to serve as the Compensation Committee’s third member and (2) a new Chair of the Compensation Committee at the Board meeting immediately following the Annual Meeting.

The purpose of our Compensation Committee is to discharge our Board’s responsibilities relating to compensation of our directors, executive officers and employees and to administer our equity compensation and other benefit plans. In carrying out these responsibilities, our Compensation Committee reviews all components of executive officer compensation for consistency with our Compensation Committee’s primary objectives of attracting and retaining key management personnel, driving long-term strategic values and enhancing stockholder value. The Compensation Committee charter specifies that the Compensation Committee will, among other things:

22

---

 

Under the Compensation Committee charter, the Compensation Committee may, in its discretion, delegate its duties to a subcommittee consisting of one or more of its members and delegate authority to specified executive officers to review and approve the compensation of nonexecutive officer employees. At the direction of the Nominating and Governance Committee, the Compensation Committee conducts an annual performance evaluation and reports to the Board on its results.

The charter of the Compensation Committee grants the Compensation Committee full authority to obtain, at our expense, advice and assistance from compensation consulting firms, legal counsel and other advisors as it deems appropriate to assist it in the evaluation of the compensation of directors, the principal executive officer or the other executive and non‑executive officers of the Company, and the fulfillment of its other duties.

Nominating and Governance Committee  

The charter for the Nominating and Governance Committee requires the committee to consist of not less than two independent directors, subject to the Nasdaq listing rules. Our Nominating and Governance Committee currently consists of three directors, Mr. Ringo (Chair), Mr. Altig and Mr. Holubiak. The Board has determined that each of Mr. Ringo, Mr. Altig and Mr. Holubiak are independent under the Nasdaq listing rules. Due to Mr. Holubiak’s retirement from the Board as of the Annual Meeting, at the Board meeting immediately following the Annual Meeting, the Board will appoint a director that meets the Nasdaq requirements to serve as the Nominating and Governance Committee’s third member.

The primary purpose of our Nominating and Governance Committee is to select, and recommend to our Board, director nominees for each election of directors and recommend any corporate governance guidelines it deems appropriate. Additionally, the Nominating and Governance Committee has general oversight of our compliance with legal and regulatory requirements of our business operations, other than compliance with securities laws and regulations, including our financial reporting and disclosure obligations, or anti-bribery laws, which in each case is the responsibility of the Audit Committee.  

Candidates for nomination as director may come to the attention of our Nominating and Governance Committee from time to time through incumbent directors, management, stockholders or third parties. Our Amended and Restated Bylaws contain provisions for stockholders to recommend persons for nomination as a director candidate and, subject to certain conditions, to nominate director candidates for inclusion in our proxy statement, as set forth in this proxy statement under “Deadline for Stockholder Proposals for 2023 Annual Meeting of Stockholders.” Candidates for potential nomination may be considered at meetings of our Nominating and Governance Committee at any point during the year. Such candidates will be evaluated against the criteria set forth above, and the Nominating and Governance Committee’s policy is to evaluate any recommendation for director nominees proposed by stockholders using the same criteria. If our Nominating and Governance Committee believes at any time that it is desirable that our Board consider additional candidates for nomination, the Committee may poll directors and management for suggestions or conduct research to identify possible candidates and may, if our Nominating and Governance Committee believes it is appropriate, engage a third‑party search firm to assist in identifying qualified candidates.

After director candidates have been identified, the Nominating and Governance Committee conducts a review and evaluation of the qualifications of any proposed director candidate as it deems appropriate. There is no difference in the evaluation process of a candidate recommended by a stockholder as compared to the evaluation process of a candidate identified by any of the other means described above.

If the Nominating and Governance Committee determines that a candidate should be nominated for election to the Board, the candidate’s nomination is then recommended to the Board, and the directors may in turn conduct their own review to the extent they deem appropriate. When the Board has agreed upon a candidate, such candidate is recommended to the stockholders for election at an annual meeting of stockholders or appointed as a director by a vote of the Board as appropriate.

The Nominating and Governance Committee engaged a third-party search firm in 2020 in identifying and evaluating Ms. Consylman and utilized the services of the same search firm in 2021 in identifying and evaluating Dr. Johnson-Pratt. Although Dr. Houghton was identified by our Chief Executive Officer, the same third-party search firm reviewed Dr. Houghton prior to his appointment by the Board.

All of the director nominees (William R. Ringo, Jr., Anthony E. Altig, Gina Consylman, Richard D. DiMarchi, Ph.D., Sir Michael Houghton, Ph.D., Lisa R. Johnson-Pratt, M.D., Susan Mahony, Ph.D. and John G. McHutchison, A.O., M.D.) have been recommended by the Nominating and Governance Committee to the Board for re‑election as our directors at the Annual Meeting, and the Board has approved such recommendations.

The Nominating and Governance Committee also develops and oversees an annual self-evaluation process for the Board and each of its standing committees and ensures that the results of such evaluations are reported to the Board.

Science and Technology Committee

Our Science and Technology Committee currently consists of Dr. DiMarchi (Chair), Dr. Houghton, Dr. Johnson-Pratt, Dr. Mahony and Dr. McHutchison. The primary purpose of our Science and Technology Committee is to assist the Board with oversight of our research and development activities, including to advise the Board with respect to strategic and tactical scientific matters. In furtherance of its purpose, the Science and Technology Committee reviews, among other things:

The Science and Technology Committee charter requires that the Science and Technology Committee meet at least twice per year. The Chair of the Science and Technology Committee, in consultation with the other members and management, may set meeting agendas. The Science and Technology Committee will review and assess the adequacy of its charter at least once annually and recommend changes to the Board for approval.

Code of Ethics and Code of Conduct

Our Board has adopted a Code of Ethics for our principal executive officer and all senior financial officers and a Code of Conduct applicable to all of our employees and our directors. Both codes can be found in the Corporate Governance section of the Investors section of our website at www.assemblybio.com. If we make any substantive amendments to, or grant any waivers from, the Code of Ethics or Code of Conduct, as applicable, for our principal executive officer, principal financial officer, principal accounting officer, controller or persons performing similar functions, or any officer or director, we will disclose the nature of such amendment or waiver on our website or in a Current Report on Form 8‑K.

Director Compensation

Our directors play a critical role in guiding our strategic direction and overseeing the management of our Company. The many responsibilities and risks and the substantial time commitment of being a director require that we provide adequate compensation commensurate with our directors’ workload and opportunity costs. Non-employee directors receive a combination of annual cash retainers and equity awards in amounts that correlate to their responsibilities and levels of Board participation, including service on Board committees. Dr. McHutchison does not receive separate compensation for service as a director because he is a Company employee.

The following table sets forth the annual cash compensation payable to our non‑employee directors in 2021.

24

---

 

 

 

Upon appointment or election to the Board, each new non-employee director appointed or elected is granted options to purchase 30,000 shares of our common stock, which vests over three years in three approximately equal installments on each anniversary of the date of grant. Each year, on the date of our annual meeting of stockholders, each non-employee director that is re-elected receives a grant of an equity award that will vest in full upon the earlier of the first anniversary of the grant date and the next annual meeting of stockholders. The exercise price per share of equity awards that constitute options is the fair market value of a share of our common stock on the date of the grant of the option. All options have a term of ten years. Non-employee directors elected to serve on the Board at the 2021 annual meeting of stockholders were granted options to purchase 15,000 shares of common stock.

The following table sets forth information regarding cash and non‑cash compensation earned by or paid to each of our non‑employee directors serving as directors during 2021.

Stockholder Communications

Stockholders and other interested parties may communicate with the Board by writing to Jason A. Okazaki, our Chief Operating Officer and Corporate Secretary, at Assembly Biosciences, Inc., 331 Oyster Point Blvd., Fourth Floor, South San Francisco, California 94080. Upon receipt of a stockholder communication indicating a desire to communicate with the Board, Mr. Okazaki will review the communication and determine whether the communication should be directed to the Board or any individual director. All communications will be forwarded in this manner; provided, however, that Mr. Okazaki reserves the right not to forward to the Board or any individual director any materials that he deems in his reasonable discretion to be unduly frivolous, hostile, threatening or similarly inappropriate for communication to the Board or any individual director.

Stockholder Engagement

General

Senior management regularly engages with our stockholders at industry conferences and investor meetings. In response to feedback gained through our engagement program, we remain focused on delivering on our research and clinical development strategies, and we continue to enhance the transparency and disclosure of our financial, operational and environmental and governance performance.

Our investor relations team keeps the Board regularly updated on the views of stockholders and provides reports from financial and other advisers concerning institutional stockholder feedback.

Say on Pay Outreach

In response to our 2021 Say on Pay proposal, in which approximately 74% of the shares voted supported our executive compensation program, we conducted a stockholder outreach program in October and November 2021. During our outreach efforts, we contacted our top 20 stockholders as of September 2021, which represented 53% of our outstanding shares, held by nine fund managers, one private equity fund, nine hedge funds and one venture capital firm.

Three stockholders, each in our top five holders, requested a meeting in response to our outreach. The meetings focused primarily on our executive compensation program, particularly a perceived misalignment between pay and performance. In each meeting, we explained that we have experienced recent steep declines in our stock price, as the stock price fell approximately 70% in 2020 and approximately 62% in 2021. These declines have resulted from a combination of (1) disappointing results of Study 211 released in late 2020, in which all patients relapsed, indicating that no patients were cured of HBV and (2) our discontinuation of clinical development of 2158 due to elevated ALT levels in our Phase 2 study, which was announced in September 2021. While these results can be expected to impact our stock price, the declines have been exacerbated by well documented, sector-wide weakness in the biotech market that began in early 2021 and accelerated near the end of 2021.

As a result of these steep declines, use of models relying on Grant Date Fair Value (GDFV) of equity awards result in an apparent disconnect between pay and performance. We believe focus on Realizable Pay (RP) is a more appropriate measurement of alignment. For additional information regarding GDFV and RP, see “Executive Compensation—Executive Summary—Alignment of Pay and Performance.”

We plan to continue our robust outreach efforts and to engage in additional outreach in the lead up to our 2022 Say on Pay vote.

Environmental, Social and Governance Focus

Management and the Board recognize that, as we continue to grow and advance our pipeline of product candidates, it is important to also focus our corporate responsibility programs on issues that support long-term sustainability of our operations and manage relevant environmental, social and governance (ESG) risks. In 2020, we highlighted our programs, achievements and future plans on ESG issues by adding a sustainability section to our corporate website, which can be found at www.assemblybio.com/sustainability, and we updated this site in 2021. The information posted on our website is not intended to be incorporated into this proxy statement.

Proposal No. 2: Advisory Vote to Approve Our Named Executive Officers’ Compensation

General

Under the Dodd‑Frank Wall Street Reform and Consumer Protection Act of 2010 (the Dodd‑Frank Act) and Section 14A of the Exchange Act, our stockholders are entitled to vote to approve, on a non-binding advisory basis, the compensation of our named executive officers (NEOs) as disclosed in this proxy statement in accordance with SEC rules. This vote is commonly known as the “Say on Pay” vote. This vote is not intended to address any specific item of compensation, but rather our NEOs’ overall compensation and the philosophy, policies and practices described in this proxy statement.

We provide our stockholders with the opportunity to cast an advisory vote on our NEOs’ compensation every year. Approximately 74% of the votes cast on our Say on Pay vote were voted in favor of the proposal in 2021.

Our NEOs’ compensation addressed by this vote is disclosed in the “Executive Compensation” section of this proxy statement and the compensation tables and the related narrative disclosure contained in this proxy statement. As discussed in these disclosures, our compensation philosophy is to provide competitive overall compensation that attracts and retains top performers. To achieve these goals, our compensation program is structured to:

Accordingly, the Board is asking stockholders to indicate their support for the compensation of our NEOs as described in this proxy statement by casting a non‑binding advisory vote “FOR” the following resolution:

“RESOLVED, that the Company’s stockholders hereby approve, on a non-binding advisory basis, the compensation of the Company’s named executive officers, as disclosed in the proxy statement for the 2022 Annual Meeting of Stockholders pursuant to the compensation disclosure rules of the Securities and Exchange Commission, including the compensation tables and narrative discussion in the proxy statement for the 2022 Annual Meeting of Stockholders.”

The “Executive Compensation” section of this proxy statement contains more details on our NEOs’ compensation, and we urge you to read it carefully before casting your vote on this proposal. Because the vote is advisory, it is not binding on us, the Board or the Compensation Committee. Nevertheless, as demonstrated by our stockholder outreach in October and November 2021 and continued engagement efforts going forward, the views expressed by our stockholders, whether through this vote or otherwise, are important to our management, the Board and the Compensation Committee. Our management, the Board and the Compensation Committee intend to consider the results of this vote in making recommendations and determinations in the future regarding executive compensation arrangements and our executive compensation principles, policies and procedures.

We submit the compensation of our NEOs to our stockholders for a non-binding advisory vote on an annual basis. Accordingly, the next stockholder advisory vote on the compensation of our NEOs after the Annual Meeting is expected to take place at the 2023 Annual Meeting of Stockholders. The next non-binding advisory vote on the frequency of such non-binding advisory votes will occur no later than our 2024 annual meeting of stockholders.

27

Required Vote

Assuming a quorum is present, to be approved, the affirmative vote of the majority of the votes cast on Proposal No. 2 must be voted “FOR” the approval, on a non-binding advisory basis, of our NEOs’ compensation as disclosed in this proxy statement. Abstentions and broker non-votes will not be considered towards vote totals on Proposal No. 2 and will have no effect on the outcome of the vote.

Recommendation of the Board of Directors

THE BOARD OF DIRECTORS RECOMMENDS A VOTE “FOR” THE APPROVAL, ON A NON-BINDING ADVISORY BASIS, OF OUR NAMED EXECUTIVE OFFICERS’ COMPENSATION.

Matters Relating to Our Independent Registered Public Accounting Firm

Pre-Approval Policies and Procedures

The charter of the Audit Committee provides for Audit Committee preapproval of all auditing services and the terms thereof (which may include providing comfort letters in connection with underwritten securities offerings) and non‑audit services (other than non‑audit services prohibited under Section 10A(g) of the Exchange Act or the applicable rules of the SEC or the Public Company Accounting Oversight Board) to be provided to us by our independent registered public accounting firm. The preapproval requirement is waived with respect to the provision of non‑audit services for us if the “de minimis” provisions of Section 10A(i)(1)(B) of the Exchange Act are satisfied. This authority to preapprove non‑audit services may be delegated to one or more members of the Audit Committee, who shall present all decisions to pre‑approve an activity to the full Audit Committee at its first meeting following such decision. The Audit Committee pre‑approved all services provided by Ernst & Young LLP, our independent registered public accounting firm for the fiscal years ended December 31, 2021 and 2020.

Fees and Services

The following table represents aggregate fees billed to us for services related to the fiscal years ended December 31, 2021 and 2020 by Ernst & Young LLP, our independent registered public accounting firm:

 

All of the services described above were pre-approved by our Audit Committee. The Audit Committee concluded that the provision of these services by Ernst & Young LLP would not affect their independence.

Report of the Audit Committee of the Board of Directors

The Audit Committee reviews our financial reporting process on behalf of the Board. Management has the primary responsibility for the preparation and integrity of the consolidated financial statements and the reporting process, including establishing and monitoring the system of internal financial controls.

Proposal No. 3: Ratification of the Selection of the Independent Registered Public Accounting Firm

General

The Audit Committee has selected Ernst & Young LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2022. Ernst & Young LLP has served as our independent registered public accounting firm since 2015.

Neither our Amended and Restated Bylaws nor other governing documents or law require stockholder ratification of the selection of Ernst & Young LLP as our independent registered public accounting firm. However, the Board is submitting the selection of Ernst & Young LLP to the stockholders for ratification as a matter of good corporate practice. If the stockholders fail to ratify the selection, the Audit Committee will reconsider whether to retain Ernst & Young LLP. Even if the selection is ratified, the Audit Committee, in its discretion, may direct the appointment of different independent registered public accounting firm at any time during the year if the Audit Committee determines that such a change would be in the best interest of the Company and its stockholders. Representatives of Ernst & Young LLP are expected to attend the Annual Meeting, where they will have an opportunity to make a statement and be available to respond to appropriate questions.

Required Vote

Assuming a quorum is present, to be approved, the affirmative vote of the majority of the votes cast on Proposal No. 3 must be voted “FOR” the ratification of the selection of Ernst & Young LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2022. Abstentions and broker non‑votes will not be considered towards vote totals on Proposal No. 3.

Recommendation of the Board of Directors

THE BOARD OF DIRECTORS RECOMMENDS A VOTE “FOR” THE RATIFICATION OF THE SELECTION OF ERNST & YOUNG LLP AS OUR INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM.

Proposal No. 4: Approval of an Amendment to the Assembly Biosciences, Inc. 2018 Stock Incentive Plan

Background

On May 30, 2018, we adopted the Assembly Biosciences, Inc. 2018 Stock Incentive Plan, which has been subsequently amended by Amendment No. 1 to Assembly Biosciences, Inc. 2018 Stock Incentive Plan effective as of May 17, 2019, Omnibus Amendment to Assembly Biosciences, Inc. Stock Plans effective as of March 11, 2020, Amendment No. 3 to Assembly Biosciences, Inc. 2018 Stock Incentive Plan, effective as of June 11, 2020 and Amendment No. 4 to Assembly Biosciences, Inc. 2018 Stock Incentive Plan, effective as of May 20, 2021 (as amended from time to time, the 2018 Plan). The 2018 Plan provides for the grant of equity awards to our employees, non-employee directors and consultants and is necessary to ensure that we can continue to grant equity awards to eligible recipients at levels determined to be appropriate by the Board, the Compensation Committee and/or the Chief Executive Officer pursuant to his Board delegated authority.

As of March 28, 2022, there were stock options to acquire 6,048,294 shares of common stock and 13,635 cash settled stock appreciation rights (SARs) outstanding under our equity compensation plans. In addition, there were 529,052 shares subject to unvested restricted stock units (RSUs) with time-based vesting and 374,214 shares subject to unvested RSUs with performance-based vesting outstanding under our equity compensation plans. As of March 28, 2022, there were approximately 4,442,171 shares of common stock available and unallocated under our equity compensation plans, of which 234,169 shares are only issuable as inducement awards to new employees under our 2017 Inducement Award Plan, our 2019 Inducement Award Plan and our 2020 Inducement Award Plan collectively. As a result, as of March 28, 2022, there were approximately 4,208,002 shares of common stock available under our shareholder approved plans, of which 3,477,513 shares of common stock remain available and unallocated for issuance under the 2018 Plan.

After the record date for the Annual Meeting, on March 29, 2022, we issued an aggregate of annual performance equity awards to our employees totaling 2,204,825 shares or common stock, which consisted of stock options to acquire 1,460,550 shares of our common stock, 475,275 RSUs with time-based vesting, 255,000 RSUs with performance-based vesting and 14,000 cash settled SARs under our 2018 Plan. As a result, as of March 29, 2022, there were 1,272,688 shares of common stock available and unallocated for issuance under the 2018 Plan.

We also expect to issue an additional 140,000 stock options under the 2018 Plan at the Board meeting immediately following the Annual Meeting in connection with the re-election of seven non-employee directors.

On March 10, 2022, the Board, upon the recommendation of the Compensation Committee and subject to the approval of our stockholders at the Annual Meeting, approved Amendment No. 5 to the 2018 Plan (the Amendment) to increase the number of shares reserved under the 2018 Plan from 6,600,000 to 8,600,000 (as further amended, the Amended Plan). The proposed increase of 2,000,000 shares equals approximately 4.2% of the Company’s outstanding shares. It should be noted that in Proposal No. 6 (approval of a stock option exchange program for non-executive employees) is approved and the exchange is conducted, shares from exchanged options that are in excess of the shares needed to issue replacement grants (as described in Proposal No. 6) will not be returned to the plan pool under the 2018 Plan.

Purpose

The purpose of the Amended Plan is to encourage ownership in the Company by our employees, directors and consultants and our affiliates whose long-term employment by, or involvement with, us is considered essential to our continued progress. Our culture of ownership aligns the interests of equity award recipients and stockholders and also permits award recipients to share in our success alongside our stockholders. The Amended Plan provides an essential component of the total compensation package offered to our employees and other 2018 Plan participants. It reflects the importance that we place on both motivating and retaining employees and other 2018 Plan participants to achieve superior results over the long term and rewarding our employees and other 2018 Plan participants based on long-term achievements. We strongly believe that our equity compensation programs and emphasis on employee and non-employee director stock ownership have been integral to building and retaining a strong employee base. We also believe these programs have contributed to our continued pipeline progress and serve as valuable motivation for or employees as we seek to achieve superior performance in the future. All of our, and our affiliates’, employees, directors and our consultants are eligible to participate in the Amended Plan.

32

---

 

The purpose of the Amendment is to increase the number of shares reserved for issuance under the 2018 Plan by 2,000,000 shares. We believe the ability to grant market-competitive equity awards is a necessary and powerful recruiting and retention tool for us to attract and retain the quality and number of personnel we need to continue the forward momentum of our business. Our employees are critical to the continued development of: (1) our lead core inhibitor product candidate in our hepatitis B virus (HBV) program, vebicorvir (VBR), which is in ongoing Phase 2 clinical studies evaluating VBR in combination with other HBV therapeutics with different mechanisms of action, the advancement of our next generation core inhibitor product candidates; (2) ABI-H3733 (currently in Phase 1b clinical studies) and ABI-4334 (currently undergoing Investigational New Drug enabling studies), through clinical development; (3) a HBV/hepatitis D virus (HDV) entry inhibitor, molecules that disrupt covalently closed circular DNA (cccDNA); and (4) a small molecule targeting a novel, currently undisclosed target to add to combination treatments with our core inhibitor product candidates, as well as other small molecules targeting other novel, currently undisclosed targets outside of HBV.

We believe that 2,000,000 shares is a modest increase that will be sufficient to meet our retention and anticipated hiring needs until the next annual meeting of stockholders and will underpin one of our core compensation philosophies, pay for performance, by giving our employees and other 2018 Plan participants the opportunity to share in our long-term success and motivate the creation of long-term stockholder value through equity compensation.  

Rationale

We believe you should vote to approve the Amendment for the following reasons:

2019 – 2021 Burn Rate and Outstanding Awards Overhang

The following tables provide certain additional information regarding our equity incentive program and our equity burn rate over the last three years and overhang as of March 29, 2022. Note that burn rate and overhang are calculated on a non-diluted basis.

Burn Rate

In late 2019, we began the transition of our leadership from our remaining founders to an executive team led by John G. McHutchison, A.O., M.D. After Dr. McHutchison joined us, Luisa M. Stamm, M.D., Ph.D., our Chief Medical Officer, and a new Chief Financial Officer, who left the Company in June 2021, each joined in 2019. In 2020, Jason A. Okazaki, now our Chief Operating Officer, joined as Chief Legal and Business Officer, William E. Delaney IV, Ph.D. joined as Chief Scientific Officer and Nicole S. White, Ph.D., now our Chief Manufacturing Officer, joined as SVP of Pharmaceutical Development and Manufacturing. In each case, these critical hires were offered total compensation packages that included inducement equity grants.

34

---

 

In 2021, we completed the wind-down of our Microbiome program, which included all of our Microbiome staff leaving the company, and the Chief Financial Officer hired in 2019 left the Company. Both of these events resulted in significant forfeitures of awards. Also in 2021, due to the steep declines of our stock price in 2020 and 2021, we implemented a broad-based supplemental equity award program, which led to more awards being granted than occurs in a typical year. For full details regarding the supplemental equity award program, see “Executive Compensation—Summary Compensation Table—Narrative Disclosure to Summary Compensation Table—Long-Term Equity Incentive Awards—Performance-Based Retention Equity Grants.”

 

Outstanding Awards Overhang

Prior to 2018, in connection with our founders and certain other employees leaving the Company, it was the Company’s practice to extend stock options until the end of their ten-year term rather than cause them to be forfeited following those employees’ departures. No members of the leadership team that began and continued that practice remain with the Company. This practice has caused our overhang to be higher than many of our peer companies due to the large number of equity awards held by former employees. As time passes, we expect our overhang pressure to be significantly reduced. For example, 927,238 stock options held by former members of management are scheduled to expire in 2024. However, until these legacy awards expire or are exercised, it is imperative that we maintain a sufficient number of shares under the 2018 Plan for the reasons described above under “Rationale.”

 

35

---

 

We also expect to issue an additional 140,000 stock options under the 2018 Plan at the Board meeting immediately following the Annual Meeting in connection with the election of seven non-employee directors.

The closing price of our common stock as reported on The Nasdaq Global Select Market on March 28, 2022, the record date for this annual meeting, was $2.18.

Material Terms of the Amended Plan

The following is a summary of the principal provisions of the Amended Plan and its operation, including the proposed Amendment. A copy of the proposed Amendment is attached as Appendix A to this proxy statement. A copy of the full 2018 Plan (as amended to date), with proposed deletions indicated by strike-out and proposed revisions to be made by the Amendment indicated by bold and underline, is attached as Appendix B to this proxy statement and is incorporated herein by reference. The following description of the Amended Plan does not purport to be complete and is qualified in its entirety by reference to Appendix B. Capitalized terms used in this summary and not otherwise defined will have the meanings ascribed to such terms in the Amended Plan.

Purpose of the Amended Plan. The purpose of the Amended Plan is to encourage ownership in the Company by employees, directors and consultants of the Company and its affiliates whose long-term employment by or involvement with the Company is considered essential to our continued progress and, thereby, aligning the interests of the award recipients and stockholders and permitting the award recipients to share in our success. The Amended Plan provides an essential component of the total compensation package offered to our employees and other plan participants. It reflects the importance we place on motivating employees and other plan participants to achieve superior results over the long-term and paying employees and other plan participants based on such achievements. We strongly believe that our equity compensation programs and emphasis on employee and non-employee director stock ownership have been integral to our progress and that a continuation of, and emphasis on, those programs is necessary for us to achieve superior performance in the future. All of our employees, directors and consultants and those of our affiliates are eligible to participate in the Amended Plan.

Types of Awards.  The Amended Plan provides for the grant of non-qualified and incentive stock options (Options), SARs, dividend equivalent rights, unrestricted stock, restricted stock, RSUs or other rights or benefits under the Amended Plan (collectively, Awards).

Shares Subject to the Amended Plan.  No more than 8,600,000 shares of common stock may be issued pursuant to Awards under the Amended Plan. The number of shares available for Awards, as well as the terms of outstanding Awards, are subject to adjustment as provided in the Amended Plan for stock splits, stock dividends, recapitalizations and other similar events.

Each share of common stock subject to an Award granted pursuant to the Amended Plan will reduce the aggregate number of shares available under the Amended Plan by one share of common stock. Any shares of common stock that again become available for issuance under the Amended Plan due to a forfeiture, expiration or cancellation of an Award (or if the Award otherwise becomes unexercisable) will generally be added back to the aggregate plan limit of the Amended Plan in this same manner and such shares will again be available for subsequent Awards, except as prohibited by law. In the event any Option or other Award granted under the Amended Plan is exercised through the tendering of shares of common stock (either actually or through attestation) or withholding shares of common stock, or in the event tax withholding obligations are satisfied by tendering or withholding shares of common stock, any shares of common stock so tendered or withheld shall not again be available for awards under the Amended Plan. Shares of Common Stock subject to a SAR granted pursuant to Section 6(k) of the Amended Plan that are not issued in connection with cash or stock settlement of the exercise of the SAR shall not again be available for award under the Amended Plan. Shares of common stock reacquired by the Company on the open market or otherwise using cash proceeds from the exercise of Options shall not be available for awards under the Amended Plan.

Director Compensation Limit. The Amended Plan provides that the grant date value of all Awards awarded under the Amended Plan and all other cash compensation paid by the Company to any non-employee director in any calendar year shall not exceed $1,000,000.

Administration. The Amended Plan will be administered by the Board or a committee designated by the Board (the Committee), which committee is constituted in such a manner as to satisfy the applicable laws and to permit such

grants and related transactions under the Amended Plan to be exempt from Section 16(b) of the Exchange Act in accordance with Rule 16b-3. Once appointed, such Committee shall continue to serve in its designated capacity until otherwise directed by the Board. Currently, the Compensation Committee generally serves as the Committee specified in the Amended Plan and acts as the administrator thereunder; however, the Board delegated authority to our Chief Executive Officer acting as a committee of one to serve as the administrator in the context of granting awards under the Amended Plan to newly hired employees or in connection with promotions to individuals that are not Section 16 officers, direct reports of the Chief Executive Officer or above the level of Vice President. Awards granted by the Chief Executive Officer are limited to a preset range prepared in consultation with our Compensation Consultant and consistent with our compensation philosophy. We refer to the entity or individual administering the Amended Plan as the Administrator.

Subject to the terms of the Amended Plan, the Administrator has express authority to determine the employees, directors or consultants who will receive Awards, the number of shares of common stock or other consideration to be covered by each Award, and the terms and conditions of Awards. The administrator has broad discretion to prescribe, amend and rescind rules relating to the Amended Plan and its administration, to interpret and construe the Amended Plan and the terms of all Award agreements, and to take all actions necessary or advisable to administer the Amended Plan or to effectuate its purposes. Subject to the terms of the Amended Plan, the administrator may accelerate the vesting of any Award, allow the exercise of unvested Awards, and may modify, replace, cancel or renew any Award.

Indemnification. We will indemnify and defend members of the Committee and their delegates to the extent permitted by law on an after-tax basis against all reasonable expenses, including attorneys’ fees, actually and necessarily incurred in connection with the defense of any claim, investigation, action, suit or proceeding, or in connection with any appeal therein, to which they or any of them may be a party by reason of any action taken or failure to act under or in connection with the Amended Plan, or any Award granted thereunder, and against all amounts paid by them in settlement thereof (provided such settlement is approved by the Company) or paid by them in satisfaction of a judgment in any such claim, investigation, action, suit or proceeding, except in relation to matters as to which it shall be adjudged in such claim, investigation, action, suit or proceeding that such person is liable for gross negligence, bad faith or intentional misconduct; provided, however, that within 30 days after the institution of such claim, investigation, action, suit or proceeding, such person shall offer to us, in writing, the opportunity at our expense to defend the same.

Minimum Vesting. Time-based awards granted to employees under the Amended Plan are subject to a one-year minimum vesting requirement other than in the case of death, disability, retirement, separation of service or a Corporate Transaction. Time-based awards granted to directors under the Amended Plan may not vest until the earlier of one year from the grant date and the next annual meeting of the stockholders, other than in the case of death, disability or a Corporate Transaction.

Eligibility. The Administrator may grant Options that are intended to qualify as incentive stock options (ISOs) only to employees of the Company or an affiliate that is a “parent corporation” or “subsidiary corporation” within the meaning of Section 424 of the Code, and may grant all other Awards to any employee, director or consultant. The Amended Plan and the discussion below use the term “Grantee” to refer to the holder of an Award, or the shares of common stock issuable or issued upon exercise, vesting or settlement of an Award, under the Amended Plan.

Options. Options granted under the Amended Plan provide Grantees with the right to purchase shares of common stock at a predetermined exercise price. The Administrator may grant Options that are intended to qualify as ISOs or Options that do not so qualify (Non-Qualified Stock Options). To qualify as ISOs, Options must meet additional federal tax requirements, including a $100,000 limit on the value of shares subject to ISOs that first become exercisable by a Grantee in any one calendar year.

Exercise Price of Options. The exercise price of ISOs granted to Grantees who own more than ten percent of the common stock of the Company or an affiliate on the grant date of the ISO may not be less than 110% of the fair market value of the shares of common stock subject to the ISO on the grant date. The exercise price of all other Options may not be less than 100% of the fair market value of the shares of common stock subject to the Option on the grant date.

37

---

 

Exercise of Options. To the extent exercisable in accordance with the applicable Award agreement, each Option may be exercised in whole or in part, and from time to time during its term, subject to earlier termination relating to a Grantee’s termination of continuous service. With respect to Options, the Administrator has the discretion to accept payment of the exercise price by any of the following methods (or any combination of them): cash or check in U.S. dollars, promissory note with such recourse, interest, security and redemption provisions as the Administrator determines, surrender of shares of common stock, broker assisted exercise, with respect to Options that are not ISOs, by net exercise or by past or future services rendered to the Company or an affiliate. No more than 4,600,000 shares of common stock may be granted in the form of incentive stock options.

Prohibition on Repricing. Except in connection with certain corporate adjustment events, we may not, without stockholder approval, amend an Award granted under the Amended Plan to reduce the Award’s exercise price per share, cancel and regrant new Awards with lower prices per share than the original price per share of the cancelled Awards, or cancel any Awards in exchange for cash or the grant of replacement Awards with an exercise price that is less than the exercise price of the original Awards, essentially having the effect of a repricing.

Restricted Stock and Restricted Stock Units. The Administrator may grant (1) shares of restricted stock that are forfeitable until certain vesting requirements are met and (2) RSUs that represent the right to receive payment, in cash or in shares of common stock or other securities or a combination thereof, subject to the passage of time and continuous service or the attainment of performance criteria as established by the Administrator. The Administrator has discretion to determine the terms and conditions under which a Grantee’s interests in restricted stock and RSUs become vested and non-forfeitable.

Unrestricted Stock. The Administrator may grant unrestricted stock in lieu of paying cash compensation.

Dividend Equivalent Rights. The Administrator may grant awards of dividend equivalent rights, which entitle the Grantee to compensation measured by dividends paid with respect to shares of common stock.

Income Tax Withholding. As a condition for the issuance of shares of common stock pursuant to Awards, the Amended Plan requires the Grantee to make such arrangements as we may require for satisfaction of any applicable federal, state, local or foreign withholding tax obligations that may arise in connection with the Award or the issuance of shares of common stock. Subject to approval by the Administrator, Grantees may elect to have their tax withholding obligations satisfied by tendering previously owned shares of common stock or authorizing the Company to withhold shares of common stock to be issued pursuant to exercise or vesting. Any shares held back to satisfy such tax withholding will not be available for future issuance under the Amended Plan.

Transferability. Unless the Administrator provides otherwise, in its sole discretion, no Award may be sold, pledged, assigned, hypothecated, transferred, or disposed of in any manner other than by will or by the laws of descent or distribution and may be exercised, during the lifetime of the Grantee, only by the Grantee. Notwithstanding the foregoing, the Grantee may designate one or more beneficiaries of the Grantee’s Award in the event of the Grantee’s death on a beneficiary designation form provided by the Administrator.

Certain Corporate Transactions. Effective upon the consummation of a Corporate Transaction, all outstanding Awards under the Amended Plan shall terminate unless they are assumed or replaced in connection with the Corporate Transaction. To the extent all outstanding Awards granted under the Amended Plan shall terminate, except as may be otherwise expressly provided in the relevant Award Agreement, all Awards with solely time-based vesting that are not vested and/or exercisable immediately prior to the effective time of the Corporate Transaction shall become fully vested and exercisable as of immediately prior to the effective time of the Corporate Transaction and all Awards with conditions and restrictions relating to the attainment of performance goals shall be deemed to vest and become nonforfeitable as of the Corporate Transaction as provided in the relevant Award Agreement or if not provided for in the relevant Award Agreement shall be deemed to vest and become nonforfeitable as of the Corporate Transaction assuming the higher of (a) achievement of all relevant performance goals at the “target” level (prorated based upon the length of time within the performance period that has elapsed prior the Corporate Transaction or partial achievement of the performance goals), or (b) actual achievement of all relevant performance goals as of the date of such Corporate Transaction. In the event of such termination of the Awards, the Company shall have the option (in its sole discretion) to (1) make or provide for a payment, in cash or in kind, to the Grantees holding Options and SARs, in exchange for the cancellation thereof, in an amount equal to the difference between (A) the Sale Price multiplied by the number of Shares subject to outstanding Options and SARs and (B) the aggregate exercise price of all such outstanding Options and SARs (provided that, in the case of an Option or SAR with an exercise price equal to or more than the Sale Price, such Option or SAR shall be cancelled for no

consideration); or (2) permit each Grantee, within a specified period of time prior to the consummation of the Corporate Transaction as determined by the Administrator, to exercise all outstanding Options and SARs (to the extent then exercisable including due to acceleration as contemplated by Section 13(a) of the Amended Plan if the Awards are not assumed or replaced) held by such Grantee as of immediately prior to the effective time of the Corporate Transaction. In the event of a termination of Awards pursuant to Section 13(a) of the Amended Plan, the Company shall also have the option (in its sole discretion) to make or provide for a payment, in cash or in kind, to the Grantees holding other Awards in an amount equal to the Sale Price multiplied by the number of vested Shares under such Awards. For purposes of Section 13(a) of the Amended Plan, “Sale Price” means the value as determined by the Administrator of the consideration payable, or otherwise to be received by stockholders, per share pursuant to a Corporate Transaction.

The Administrator has the authority, exercisable either in advance of any actual or anticipated Corporate Transaction or at the time of an actual Corporate Transaction and exercisable at the time of the grant of an Award under the Amended Plan or any time while an Award remains outstanding, to provide for the full or partial automatic vesting and exercisability of one or more outstanding unvested Awards under the Amended Plan and the release from restrictions on transfer and repurchase or forfeiture rights of such Awards in connection with a Corporate Transaction on such terms and conditions as the Administrator may specify. The Administrator also shall have the authority to condition any such Award vesting and exercisability or release from such limitations upon the subsequent termination of the continuous service of the Grantee within a specified period following the effective date of the Corporate Transaction. The Administrator may provide that any Awards so vested or released from such limitations in connection with a Corporate Transaction shall remain fully exercisable until the expiration or sooner termination of the Award. Any ISOs accelerated in connection with a Corporate Transaction shall remain exercisable as an ISO under the Code only to the extent the $100,000 limitation of Section 422(d) of the Code is not exceeded.

“Corporate Transaction” means any of the following transactions, provided, however, that the Administrator shall determine under (4) and (5) whether multiple transactions are related, and its determination shall be final, binding and conclusive: (1) a merger or consolidation in which we are not the surviving entity, except for a transaction the principal purpose of which is to change the state in which we are incorporated; (2) the sale, transfer or other disposition of all or substantially all of our assets; (3) the complete liquidation or dissolution of the Company; (4) any reverse merger or series of related transactions culminating in a reverse merger (including, but not limited to, a tender offer followed by a reverse merger) in which we are the surviving entity but (A) the shares of common stock outstanding immediately prior to such merger are converted or exchanged by virtue of the merger into other property, whether in the form of securities, cash or otherwise, or (B) in which securities possessing more than 50% of the total combined voting power of our outstanding securities are transferred to a person or persons different from those who held such securities immediately prior to such merger or the initial transaction culminating in such merger; or (5) acquisition in a single or series of related transactions by any person or related group of persons (other than the Company or by a Company-sponsored employee benefit plan) of beneficial ownership (within the meaning of Rule 13d-3 of the Exchange Act) of securities possessing more than 50% of the total combined voting power of our outstanding securities.

Term of the Amended Plan; Amendments and Termination.  The term of the Amended Plan is ten years from May 30, 2018, except that no ISOs may be granted after April 5, 2028. The Board may, from time to time, amend, alter, suspend, discontinue or terminate the Amended Plan; provided, that any amendment to increase the number of shares of common stock available for Awards under the Amended Plan and certain other amendments will be subject to stockholder approval. Additionally, no amendment, suspension or termination of the Amended Plan shall materially and adversely affect Awards already granted unless it relates to an adjustment pursuant to certain transactions that change our capitalization or it is otherwise mutually agreed between the Grantee and the Administrator.

Notwithstanding the foregoing, the Administrator may adopt such amendments to the Amended Plan and the applicable award agreement or adopt other policies and procedures (including amendments, policies and procedures with retroactive effect), or take any other actions, that the Administrator determines are necessary or appropriate to (1) exempt the Award from Section 409A of the Code and/or preserve the intended tax treatment of the benefits provided with respect to the Award, or (2) comply with the requirements of Section 409A of the Code and related Department of Treasury guidance.

Expected U.S. Federal Income Tax Consequences. The following is a brief summary of certain U.S. federal tax consequences of certain transactions under the Amended Plan. This summary is not intended to be complete and does not describe state or local tax consequences. Grantees in the Amended Plan should review the current tax

treatment with their individual tax advisors at the time of grant, exercise, vesting or any other transaction relating to an Award or the underlying shares.

Under the Code, we will generally be entitled to a deduction for U.S. federal income tax purposes at the same time and in the same amount as the ordinary income that Grantees recognize pursuant to Awards. For Grantees, the expected U.S. federal income tax consequences of Awards are as follows:

Eligibility

Persons eligible to participate in the Amended Plan are our employees, directors and other consultants and those of our affiliates as selected from time to time by the Administrator in its discretion. As of March 28, 2022, approximately 112 individuals are currently eligible to participate in the Amended Plan, which includes five executive officers, 100 full-time employees who are not executive officers and seven non-employee directors. At this time, we do not have any plans to make future grants to any consultants.

New Plan Benefits

Because the grant of Awards under the Amended Plan is within the discretion of the Administrator, we cannot determine the dollar value or number of shares of common stock that will in the future be received by or allocated to any participant in the Amended Plan. Accordingly, in lieu of providing information regarding benefits that will be received under the Amended Plan, the following table provides information concerning the benefits that were received by the following persons and groups during 2021 under the 2018 Plan: (a) each named executive officer; (b) all current executive officers, as a group; (c) all current directors who are not executive officers, as a group; and (d) all employees who are not executive officers as a group.

Proposal No. 5: Amendment and Restatement of Our Certificate of Incorporation to Increase Shares of Authorized Common Stock

General

On March 10, 2022, our Board approved the amendment and restatement of our Fifth Amended and Restated Certificate of Incorporation (the Amendment and Restatement), to increase the authorized number of shares of common stock, par value $0.001 per share (Common Stock) from 100,000,000 to 150,000,000 shares and directed that the Amendment and Restatement be submitted to a vote of our stockholders at the Annual Meeting. The text of the proposed Sixth Amended and Restated Certificate of Incorporation, with proposed deletions indicated by strike-out and proposed revisions indicated by bold and underline, is attached to this proxy statement as Appendix C. If the stockholders approve this Proposal No. 5, subject to the discretion of the Board, we will promptly file the Amendment and Restatement with the Secretary of State of the State of Delaware after the Annual Meeting.

The Fifth Amended and Restated Certificate of Incorporation, which is currently in effect, authorizes the issuance of up to 105,000,000 shares of stock, of which 100,000,000 shares are designated as Common Stock and 5,000,000 shares are designated as preferred stock. No shares of preferred stock are issued and outstanding. If adopted, the Amendment and Restatement will not result in an increase in the number of authorized shares of preferred stock.

The following details the availability of our common stock as of December 31, 2021.

 

 

Because only approximately 39.4% of our total authorized Common Stock is available for future issuance, which number will be further reduced if Proposals No. 4 is approved at the Annual Meeting or if we raise additional capital through the sale and issuance of Common stock, the Board believes that it is appropriate to increase our authorized shares of Common Stock from 100,000,000 to 150,000,000.

Purpose

The Board believes it is in our best interest to increase the number of authorized shares of Common Stock to give us greater flexibility in considering and planning for future corporate needs, including, but not limited to: raising additional capital, which is needed to fund our ongoing clinical and nonclinical research programs; making long-term equity incentive awards under our equity compensation plans; attracting and retaining key employees, executive officers and directors; considering potential strategic transactions, including mergers, acquisitions and business combinations; and other general corporate purposes. The Board believes that additional authorized shares of Common Stock will enable us to take timely advantage of market conditions and favorable financing and acquisition opportunities that may become available to us without the delay and expense associated with convening a special meeting of our stockholders.

We have no current plan, commitment, arrangement, understanding or agreement regarding the issuance of the additional shares of Common Stock that will result from our adoption of the proposed Amendment and Restatement. Except as otherwise required by law or the Nasdaq listing rules, the newly authorized shares of Common Stock will be available for issuance at the discretion of the Board (without further action by the stockholders) for various future

43

---

 

corporate needs, including those outlined above. While adoption of the proposed Amendment and Restatement would not have any immediate dilutive effect on the proportionate voting power or other rights of our existing stockholders, any future issuance of additional authorized shares of our Common Stock may, among other things, dilute the earnings per share of the Common Stock and the equity and voting rights of those holding Common Stock at the time the additional shares are issued.

In addition to the corporate purposes mentioned above, an increase in the number of authorized shares of our Common Stock may make it more difficult to, or discourage an attempt to, obtain control of us by means of a takeover bid that the Board determines is not in the best interest of us and our stockholders. However, the Board does not intend or view the proposed increase in the number of authorized shares of our Common Stock as an anti-takeover measure and is not aware of any attempt or plan to obtain control of us.

Rights of Additional Authorized Shares

Any authorized shares of Common Stock, if and when issued, would be part of our existing class of Common Stock and would have the same rights and privileges as the shares of Common Stock currently outstanding. Our stockholders do not have pre-emptive rights with respect to the Common Stock, nor do they have cumulative voting rights. Accordingly, should the Board issue additional shares of Common Stock, existing stockholders would not have any preferential rights to purchase any of such shares, and their percentage ownership of our then outstanding Common Stock could be reduced.

Potential Adverse Effects of the Amendment and Restatement

Future issuances of Common Stock or securities convertible into Common Stock could have a dilutive effect on our earnings per share, book value per share and the voting power and interest of current stockholders. In addition, the availability of additional shares of Common Stock for issuance could, under certain circumstances, discourage or make more difficult any efforts to obtain control of us. The Board is not aware of any attempt, or contemplated attempt, to acquire control of us, nor is this proposal being presented with the intent that it be used to prevent or discourage any acquisition attempt. However, nothing would prevent the Board from taking any such actions that it deems to be consistent with its fiduciary duties.

Required Vote

Assuming a quorum is present, to be approved, a majority of the shares of common stock outstanding and entitled to vote on Proposal No. 5 must be affirmatively voted “FOR” the Amendment and Restatement. Abstentions and broker non-votes, if any, will be deemed a vote against Proposal No. 5.

Recommendation of the Board of Directors

THE BOARD OF DIRECTORS RECOMMENDS A VOTE “FOR” THE AMENDMENT AND RESTATEMENT OF OUR CERTIFICATE OF INCORPORATION TO INCREASE THE AMOUNT OF AUTHORIZED COMMON STOCK FROM 100,000,000 SHARES TO 150,000,000 SHARES.

Proposal No. 6: Approval of a Stock Option Exchange Program for Non-Executive Employees

Background

We are seeking stockholder approval of a stock option exchange program for our current non-executive employees that would allow these non-executive employees to exchange certain significantly out-of-the-money stock options (i.e., options with respect to which the exercise price exceeds the current market value of our common stock, also known as “underwater” stock options) for new stock options exercisable for fewer shares of our common stock with an exercise price equal to the fair market value of our common stock on the new grant date, with new vesting terms. Unless indicated otherwise, all numbers presented in this proposal are as of December 23, 2021, the date for which analysis related to the proposed stock option exchange program was performed by Aon’s Human Capital Solutions practice, part of Aon plc (Aon), our independent compensation consultant. These numbers are provided for illustrative purposes only: if the proposed stock option exchange program is approved at the Annual Meeting and implemented, an updated analysis will be conducted prior to filing the Schedule TO with the SEC in the third or fourth quarter of 2022 to effect the exchange.

Stockholder-Friendly Design

In discussing strategies to address our employees’ out-of-the-money stock options, we were particularly focused on creating a strategy that is compatible with the interests of our stockholders. We believe that the proposed stock option exchange program meets that objective by providing a more cost-effective and stockholder-friendly retention and incentive tool than simply issuing additional equity awards or paying cash compensation to retain and motivate our non-executive employees. We believe that the benefits of the proposed stock option exchange program, including reducing our overhang (meaning potential shares committed but unissued) and its approximate value-neutrality (i.e., keeping the aggregate accounting value of the current stock options surrendered and the new stock options issued approximately consistent) contribute to an alignment of the program with the interests of our stockholders. In particular (and as discussed in more detail below):

We believe that these design features, among others, create a proposed stock option exchange program that is aligned with the interests of our stockholders.

Rationale

We believe that an effective and competitive employee equity incentive program is imperative for the future growth and success of our business. We rely on our employees to implement our strategic initiatives, to expand and develop our business and to conduct the research necessary to discover product candidates and to develop and advance those product candidates toward approval by the U.S. Food and Drug Administration and comparable foreign regulatory agencies. Competition for these employees, particularly in the biotech industry, is intense and many companies use stock options as a means of attracting, motivating and retaining their employees. We use stock options as a key part of our equity incentive and retention programs because our Board believes that equity compensation encourages employees to act like owners of the business, motivating them to work toward our success and rewarding their contributions by allowing them to benefit from increases in the value of our shares alongside our stockholders.

45

When the Compensation Committee approves a stock option award, it establishes the exercise price that the employee must pay to purchase shares of our common stock when the option is exercised. The per share exercise price is set at the closing price of a share of our common stock as reported by Nasdaq on the date the stock option is issued. As a result, an employee receives value only if he or she exercises an option and sells the purchased shares at a price that exceeds the stock option’s exercise price.

We have experienced recent steep declines in our stock price, as the stock price fell approximately 70% in 2020 and approximately 62% in 2021. We believe these declines have resulted from a combination of (1) disappointing results of Study 211 of vebicorvir released in late 2020, in which all patients relapsed, indicating that no patients were cured of HBV and (2) our discontinuation of clinical development of ABI-H2158 due to elevated alanine transaminase levels in our Phase 2 study, which was announced in September 2021. The declines have been exacerbated by well documented, sector-wide weakness in the biotech market that began in early 2021 and accelerated near the end of 2021. Unfortunately, while we strive to design and develop the best product candidates, we cannot control if data is positive or negative, and we do not have any control over market dynamics in the biotech sector. Despite our two data setbacks, we have continued to progress other clinical and nonclinical studies, generate and advance next generation product candidates and expand our product candidate pipeline.

As a result of the recent decline of our stock price, many of our outstanding stock options had exercise prices significantly greater than the closing price of our common stock as reported by Nasdaq on December 23, 2021 of $2.27. Since Aon’s analysis related to the proposed stock option exchange program was conducted, our stock price has continued to decline likely because of the weak biotech market. As of the market close on March 28, 2022, the record date for the Annual Meeting, our stock price was $2.18. As of December 23, 2021, there were options to purchase 4,818,115 shares of our common stock outstanding with exercise prices ranging from $2.24 per share to $56.69 per share. These out-of-the-money options are no longer effective either performance or retention incentives.

We believe that to enhance long-term stockholder value, we need to maintain competitive employee incentive and retention programs. An equity stake in our success is a critical component of these programs. We believe the proposed stock option exchange program will provide us with an opportunity to restore for eligible participants the incentive to remain with us and to continue to contribute to the future growth and success of our business. Although we continue to believe that stock options are an important component of our employees’ total compensation, many of our employees view their existing stock options as having little or no value because of the significant difference between the option exercise prices and the current market price of our common stock. As a result, these employees’ stock options do not provide the incentive and retentive values that our Board believes is necessary to motivate our employees to increase long-term stockholder value.

When considering how best to continue incentivizing and rewarding our employees who have out-of-the-money stock options, the Compensation Committee engaged Aon to review and evaluate strategies to address this issue. Along with considering the proposed stock option exchange program, we also considered the following options: (1) do nothing; (2) increasing cash compensation; and (3) exchanging out-of-the-money stock options for RSUs. Based on Aon’s recommendations and all relevant factors, the Compensation Committee determined that a program under which employees could exchange stock options with an exercise price greater than or equal to the “Threshold Exercise Price” (described below), was most attractive for several reasons, including the following:

46

---

 

If approved by our stockholders, the proposed stock option exchange program is expected to reduce the overhang of outstanding stock options by eliminating the ineffective options that are currently outstanding and issued to our non-executive employees. Under the proposed stock option exchange program, eligible participants will receive stock options exercisable for fewer shares than the exchanged stock options. Based on the number of outstanding stock options as of December 23, 2021, and assuming that all eligible options were exchanged in the program, stock options to purchase 1,001,275 shares would have been exchanged and cancelled, while new stock options covering approximately 431,015 shares would have been issued. This would have resulted in a net reduction in the overhang of our equity awards by approximately 570,260 shares, or approximately 1.2% of our total overhang on account of stock options. The actual reduction in our overhang that may result from the option exchange program could vary significantly and is dependent upon several factors, including the commencement date of the program, the actual level of participation in the program and the actual exchange ratios. All eligible stock options that are not exchanged will remain outstanding and in effect in accordance with their existing terms.

When determining the eligibility of options for this program, the Compensation Committee (with advice from Aon) determined that stock options granted on or after August 1, 2020 would not be eligible to participate. Because the price of our stock has been depressed for over the past year, this decision was made to maximize the retentive value of our equity program, while also being conscious that these awards are intended to be long-term in nature.

Members of the Board, executive officers of the Company, former employees and consultants will not be eligible to participate in the stock option exchange program. Together, the holdings of the Board and executive officers constitute approximately 44% of our outstanding stock options as of March 28, 2022. All of these stock options will continue to be governed by their existing terms.

Exchange ratios for those eligible to participate will be designed to result in a “value for value” exchange, which means that the accounting fair value of new stock options granted will be approximately equal to the accounting fair value of the stock options that are surrendered. None of the shares subject to surrendered stock options (in excess of the replacement options issued under the exchange program) will return to our authorized share pool nor reserves for the equity plan under which they were issued or any of our other equity plans.

47

---

 

The minimum exercise price of options eligible to be exchanged will be determined by the greater of the 52-week intraday high trading price of our common stock and 1.5 times the then-current trading price of our shares (in each case as of a date shortly prior to the commencement date of the offer). Using this minimum price is designed to ensure that only outstanding options with an exercise price that is significantly out of the money will be eligible for the exchange program.

Material Terms

An overview of the key features of the proposed stock option exchange program is provided below.

Exchange Ratio

The table below illustrates for eligible stock options, the applicable exercise price range, the approximate number of options in each such range (along with the weighted average exercise price and remaining term for stock options in that category), the applicable exchange ratio and the approximate number of new stock options issuable with respect to exchanged stock options, assuming 100% participation in the offer, had the offer been commenced as of December 23, 2021. If the proposed stock option exchange program is approved, the exercise price ranges and exchange ratios will be determined immediately prior to the commencement of the stock option exchange program in a manner consistent with that used to formulate the illustration below.

We have not commenced the stock option exchange program and do not intend to do so unless our stockholders approve this Proposal No. 6. If we receive stockholder approval of the stock option exchange program, the stock option exchange program may commence at a time determined by the Board or the Compensation Committee, with terms substantially consistent with those described in this proposal. Even if the stockholders approve this proposal, the Board or the Compensation Committee may still later determine not to implement the stock option exchange program.

Upon commencement of the stock option exchange program, employees holding eligible stock options would receive written materials (the “offer to exchange”) explaining the precise terms and timing of the stock option exchange program. Employees would be given at least 20 business days (or such longer period as we may elect to keep the stock option exchange program open) to elect to exchange all, some or none of their eligible stock options, on a grant-by-grant basis, for new stock options. After the offer to exchange is closed, the eligible stock options surrendered for exchange would be cancelled, and the Compensation Committee would approve grants of new stock options to participating employees in accordance with the applicable exchange ratios and other terms of the program. At or before commencement of the exchange program, we will file the offer to exchange and other related documents with the SEC as part of a tender offer statement on Schedule TO. Employees, as well as stockholders and members of the public, will be able to access the offer to exchange and other documents we file with the SEC free of charge from the SEC’s website at www.sec.gov.

Other Matters

Treatment of Net Shares

The net shares underlying eligible stock options in excess of the shares underlying the new stock options granted in the stock option exchange program will not be returned to the pool available for issuance under the 2018 Stock Incentive Plan.

Accounting Treatment

The incremental compensation expense associated with the stock option exchange program will be measured as the excess, if any, of the fair value of each new stock option granted to participants in the program, measured as of the date the new stock options are granted, over the fair value of the stock options surrendered in exchange for the new stock options, measured immediately prior to the cancellation. We do not expect the incremental compensation expense, if any, to be material. We will recognize any such incremental compensation expense ratably over the vesting period of the new stock options.

United States Federal Income Tax Consequences

We believe the exchange of eligible stock options for new options pursuant to the option exchange program should be treated as a non-taxable exchange, and no income should be recognized for United States federal income tax purposes by us or our employees upon the grant of the new stock options. However, the U.S. Internal Revenue Service is not precluded from adopting a contrary position, and the laws and regulations themselves are subject to change. A more detailed summary of the applicable tax considerations to eligible participants will be provided to them in connection with the offer when it is commenced.

Potential Modifications to Terms to Comply with Governmental Requirements

The terms of the stock option exchange program will be described in a tender offer statement that we will file with the SEC. Although we do not anticipate that the SEC will require us to modify the terms significantly, it is possible we will need to alter the terms of the program to comply with comments from the SEC. Changes in the terms of the program may also be required for tax purposes or to comply with applicable law outside of the United States for non-U.S. participants.

Required Vote

Assuming a quorum is present, to be approved, the affirmative vote of the majority of the votes cast on Proposal No. 6 must be voted “FOR” approval of a stock option exchange program for non-executive employees. Abstentions and broker non‑votes will not be considered towards vote totals on Proposal No. 6.

Recommendation of the Board of Directors

THE BOARD OF DIRECTORS RECOMMENDS A VOTE “FOR” APPROVAL OF A STOCK OPTION EXCHANGE PROGRAM FOR NON-EXECUTIVE EMPLOYEES.

Executive Compensation

We are a “smaller reporting company” under Item 10 of Regulation S-K promulgated under the Exchange Act. The following compensation disclosure is intended to comply with the requirements applicable to smaller reporting companies. Although the rules allow us to provide less detail about our executive compensation program, the Compensation Committee is committed to providing the information necessary to help stockholders understand its executive compensation-related decisions. Accordingly, this section includes supplemental narratives that describe the 2021 executive compensation program for our named executive officers (NEOs).

Our NEOs for the fiscal year ended December 31, 2021 are:

 

 

Executive Summary

Alignment of Pay and Performance

The first priority of our compensation program is to pay for performance. When conducting an analysis of the alignment of pay for performance, we believe that it is important to ensure that the model using the most appropriate alignment measure available is selected. We believe that analysis using Realizable Pay is most appropriate for determining the alignment of our pay and performance.

Given the extreme volatility of stock prices in the biotech industry, reliance on models using Grand Date Fair Values of equity awards can result in an apparent disconnect between pay and performance, as the volatility of stock prices in this industry creates a situation in which a company’s stock price at the time of a pay for performance analysis can be far different than it was at the time that equity grants were made. This is particularly true given the downward pressure on stock prices in the biotech sector over the last two years.

We believe that Realizable Pay is a more appropriate measurement of alignment of pay and performance of our executives, including Dr. McHutchison, and is more telling, as Realizable Pay has dropped significantly as our stock price has fallen.

For Dr. McHutchison:

As demonstrated by the chart below, as our stock performance, measured by indexed total stockholder return (TSR) and depicted by the black line, has declined, so has Dr. McHutchison’s Realizable Pay—the two are very closely aligned. As our TSR increases, so too would Realizable Pay.

Say on Pay Vote

At our 2021 Annual Meeting of Stockholders, our Say on Pay proposal received support of approximately 74% of the shares voted. In response to this level of support, we conducted a stockholder outreach program in October and November 2021. During our outreach efforts, we contacted our top 20 stockholders as of September 2021, which represented 53% of our outstanding shares, held by nine fund managers, one private equity fund, nine hedge funds and one venture capital firm.

Three stockholders, each among our then-top five holders, requested a meeting in response to our outreach. The meetings focused primarily on our executive compensation program, highlighting our pay and performance philosophy and our achievements over the prior year. We were represented at each of these meetings by our Chief Operating Officer, our Chief Human Resources Officer, our SVP, Investor Relations & Corporate Affairs and our Associate General Counsel.

In each meeting, we noted that we have experienced recent steep declines in our stock price, with the stock price falling approximately 70% in 2020 and another approximately 40% in 2021 through the dates of the meetings . We

54

---

 

believe that these declines have resulted from (1) disappointing results of Study 2011 released in late 2020, in which all patients relapsed, indicating that no patients were cured of HBV and (2) our discontinuation of clinical development of 2158 due to elevated ALT levels in our Phase 2 study, which was announced in September 2021. While these results can be expected to impact our stock price, the declines have been exacerbated by well documented, sector-wide weakness in the biotech market that began in early 2021 and accelerated near the end of 2021. Despite the disappointing results from the two studies, each were critically important in the development path for finite and curative therapies for HBV. The results of the studies have provided important insights that will help us as we continue to advance the rest of our clinical and preclinical pipeline.

During our outreach, we outlined for our stockholders why we believe that focus on Realizable Pay is a more appropriate measurement of alignment of pay and performance due to the recent sharp declines in our stock price. A focus on Grant Date Fair Value of equity awards in particular results in an apparent, but not actual, disconnect between pay and performance. For additional information regarding Grant Date Fair Value and Realizable Pay, see “—Alignment of Pay and Performance.”

All of our meetings were very positive, as the stockholders were receptive to our explanation of the merits of Realizable Pay focus as opposed to Grant Date Fair Value. Each of the holders with whom we met take their own approach to analyzing the compensation practices of the companies in their portfolios. All are supportive of our pay practices, and each voted “FOR” the approval of our NEOs’ 2020 compensation. We expect to continue our robust outreach efforts and to experience continued pay for performance scrutiny. As a result, we plan to engage in additional stockholder outreach in the lead up to our 2022 Say on Pay vote.

Prior to our 2021 Say on Pay vote, our executive compensation program has consistently had the support of over 90% of the shares voted by our stockholders since 2014, including over 99% of the shares voted in 2020 regarding our 2019 executive compensation.

Compensation Philosophy and Best Practices

Our Compensation Philosophy is, “Provide Competitive Overall Compensation That Attracts, Retains and Motivates Superior Performers.” In addition to striving to adhere to this philosophy, we have instituted the following executive compensation best practices:

How We Determine Executive Compensation

Overview

The Compensation Committee believes that executive compensation should be designed to promote both our short-term and long-term goals, because pharmaceutical research and development require sustained and focused effort over many years. Accordingly, it is important that the Compensation Committee’s executive compensation program both motivate our executives to meet short- and long-term goals and align the financial interests of our employees, including our NEOs, with those of our stockholders. To achieve these goals, our compensation program is structured to:

55

---

 

At-Risk and Long-Term Pay

To implement our compensation philosophy, the Compensation Committee has determined that the primary elements of our employees’, including our NEOs’, compensation should consist of base salary, annual performance-based cash bonuses and long-term equity incentive awards, which the Compensation Committee uses to create a pay mix designed to meet the goals of our compensation philosophy. The pay mix emphasizes “at-risk” compensation in the form of (1) long-term equity awards and (2) annual performance-based cash bonuses based on the achievement of (a) Board-approved Company-wide objectives weighted to reflect their relative importance to the achievement of our goals and (b) individual performance objectives, which include certain department, group and/or team objectives applicable to the participants, tailored to responsibilities of each of our employees, including our NEOs.

As a result, the majority of the 2121 compensation paid to each of our NEOs—70%, 57% and 56% for Dr. McHutchison, Mr. Okazaki and Dr. Delaney, respectively—consisted of “at-risk” compensation.

Role of the Compensation Committee; Oversight of Executive Compensation

The Compensation Committee develops and supervises the implementation of our compensation philosophy. The Compensation Committee also has direct responsibility for reviewing and approving the compensation of our CEO and each of our other executive officers, including our NEOs. To assist the Compensation Committee in determining compensation of our other executive officers, the CEO makes recommendations to the Compensation Committee as to the specific elements (i.e., base salary, annual performance-based cash bonus and long-term equity incentive awards) of compensation. The CEO does not make recommendations, and is not present for discussions regarding his own compensation.

We generally review our compensation practices on an annual basis over the course of several meetings of the Compensation Committee and the Board. The first step in the process is for the Compensation Committee, with the support of management and the Compensation Committee’s independent outside compensation consultant, Aon’s Human Capital Solutions practice, which is a part of Aon plc (Aon), to review trends in biotech compensation practices and to recommend the list of peer companies to be used as a reference point in this compensation review process. The peer group determination process is detailed below in “—Peer Group Process.”

Our CEO, Chief Operating Officer and Chief Human Resources Officer, in addition to Aon representatives, regularly attend portions of the Compensation Committee meetings to provide analysis, information and recommendations regarding various human resources and compensation matters. Members of management generally do not participate in the Compensation Committee’s executive sessions unless invited by the Compensation Committee to provide specific information during these closed sessions. The CEO is not present for any discussion of, deliberation on, or votes related to, his compensation.

The Compensation Consultant

The Compensation Committee initially retained Aon in 2015. Aon’s fees are paid by the Company but approved by the Compensation Committee. In connection with its retention for the 2021 compensation cycle, Aon analyzed and provided advice on, among other things, the composition of our peer group, annual performance-based cash bonuses, long-term equity incentive awards as both a portion of annual compensation and as a retention tool, severance arrangements, compensation packages for executive officers being promoted, annual compensation for the

56

---

 

executive officers, compensation trends in the biotech industry and applicable public disclosures regarding our compensation programs.

Aon reports directly to the Compensation Committee, which retains sole authority to direct the work and employ Aon. The Compensation Committee regularly reviews the services that Aon provides.

The Compensation Committee assessed Aon’s independence and determined that Aon’s work did not raise any conflicts of interest in 2021. In making this assessment, the Compensation Committee considered the independence factors enumerated in Rule 10C-1(b) under the Exchange Act, including the following factors: (1) Aon does not provide any other services to us; (2) the level of fees received from us as a percentage of Aon’s total revenue is less than 1%; (3) Aon’s internal policies and procedures to prevent conflicts of interest and protect independence; (4) the Aon representatives that provide advice to the Compensation Committee neither own any of our stock nor have any business or personal relationships with members of the Compensation Committee or our executive officers; and (5) the Compensation Committee is unaware of any relationship that may exist between executive officers and Aon. The Compensation Committee continues to periodically monitor the Aon’s independence.

Peer Group Process

As part of its analysis for 2021, Aon collected and analyzed compensation information from a peer group comprised of a comparative group of biotech companies approved by the Compensation Committee.

The list of peer companies is evaluated and approved annually by the Compensation Committee based upon input from Aon and management to ensure that our peer group (1) includes companies that are similar in terms of stages of development, headcount and market capitalization, (2) appropriately represents the type of companies competing with us to attract and retain talent and (3) reflects our current and future business objectives and strategy. In September 2020, with assistance from Aon and management, the Compensation Committee revised the peer group for reference in connection with making 2021 compensation decisions and approved a peer group consisting of biopharmaceutical companies with the following characteristics:

Due to the above criteria, several companies were either added to or removed from the peer group due to M&A activity, out of scope market capitalization, headcount or stage of development. Achillion Pharmaceuticals Inc., ChemoCentryx, Inc., Chimerix Inc., Five Prime Therapeutics, Inc., Inovio Pharmaceuticals, Inc. and Principia Biopharma Inc. were each members of our 2020 Peer Group, but were removed from the 2021 Peer Group either due to the new size parameters or acquisition.

Based on these criteria, the Compensation Committee approved the revised peer group (the 2021 Peer Group) set forth below and used the 2021 Peer Group as one of multiple datapoints used in determining 2021 compensation.

57

---

 

 

 

As of September 2020, when the Compensation Consultant completed its work developing recommendations for the 2021 Peer Group, the 50^th percentile of market capitalization and headcount of the 2021 Peer Group were $733.6 million (based upon a 30-day average market capitalization) and 91 employees, respectively. Meanwhile, our market capitalization and headcount were $728.3 million (based upon a 30-day average market capitalization) and 152 employees, respectively.

After the Compensation Committee approves the list of peer companies, management and Aon present the Compensation Committee with recommendations regarding proposed adjustments to compensation elements and a variety of supporting data, including comparative compensation information from the approved peer group. The Compensation Committee generally believes that to achieve our overall compensation-related goals, our compensation elements of base salary and annual performance-based bonus opportunities should target the 50^th percentile of our peers and long-term equity incentive compensation should target the 50^th to the 75^th percentile of our peers. However, the Compensation Committee may, in its discretion, set an individual NEO’s compensation, such as Dr. McHutchison and Mr. Okazaki, above or below this level, based on that individual’s experience, criticality, amount of responsibility and either individual or Company-wide performance. Such recommendations are presented to the Compensation Committee individually for each NEO. The recommendations for the NEOs are discussed with and without our Chief Human Resources Officer and are also discussed with Aon. The CEO is not present for any discussion of, deliberation on, or votes related to, his compensation. The Compensation Committee then determines what, if any, adjustments to the compensation elements are appropriate for executive officers.

COVID-19 Pandemic

The COVID-19 pandemic created significant uncertainty regarding how we would protect our employees’ health and welfare and continue to achieve 2021 goals and reach performance targets that were set notwithstanding the pandemic. While management and the Board recognized that meeting these goals may be more challenging than in years prior to the pandemic, management and the Board set aggressive corporate goals, determined to move us forward as a company and remain aligned with our stockholders’ interests. Our Company-wide performance remained high despite challenges faced in 2021, and the Compensation Committee determined that the percentage achievement of our 2021 Company-wide goals was 97%. In addition, we successfully attracted and incentivized new talent, while retaining all our most critical talent despite challenges related to the pandemic, including the highly active 2021 talent market fueled by the U.S. economy’s strong 2021 recovery. For more information regarding our 2021 achievements, see “—2021 Accomplishments,” and for additional detail regarding the Company-wide goals set by the Board and our achievement of those goals, see “Summary Compensation Table—Narrative Disclosure to Summary Compensation Table—Annual Performance-Based Cash Bonus.”

Elements of Executive Compensation

The three principal components of our executive compensation program are base salary, annual performance-based cash bonus and long‑term equity incentive awards. Our Compensation Committee believes that each component of executive compensation must be evaluated and determined with reference to competitive market data, individual and Company-wide performance, our recruiting and retention goals, internal equity and consistency, and other

58

---

 

information it deems relevant. The Compensation Committee believes that in the biopharmaceutical/biotechnology industry, stock option and/or other equity awards are a primary motivator in attracting and retaining executives, in addition to salary and cash incentive bonuses.

In addition, significant portions of Mr. Okazaki and Dr. Delaney’s 2020 compensation were the result of one-time sign-on bonuses and inducement equity grants as partial “make whole” compensation in connection with the leadership transitions that took place.

The primary components of our compensation packages are described in more detail below.

Summary Compensation Table

The following table shows the total compensation earned by the NEOs in the last two fiscal years.

The three principal components of our executive compensation program are base salary, annual performance-based cash bonus and long‑term equity incentive awards. Our Compensation Committee believes that each component of executive compensation must be evaluated and determined with reference to competitive market data, individual and Company-wide performance, our recruiting and retention goals, internal equity and consistency, and other information deemed relevant by the Compensation Committee.

The primary components of our compensation packages and the one-time compensation elements received by our newly hired NEOs are described in more detail below.

59

Base Salary

Base salaries provide financial stability and security to our NEOs by providing a fixed amount of cash for performing their job responsibilities. Our NEOs’ base salaries are established based on each NEO’s position, criticality and scope of responsibilities, prior experience and training, then-current compensation levels and competitive market-based compensation data we review for similar positions in our industry. Base salaries are reviewed periodically and may be increased for merit reasons based on the executive’s performance, for retention reasons or if the base salary is not competitive with salaries paid by comparative companies for similar positions. Additionally, we may adjust base salaries throughout the year for promotions or other changes in the scope or breadth of an executive’s role or responsibilities. The NEOs’ annualized base salaries for 2020 and 2021, effective as of February 16 of each year or as otherwise noted, were as follows:

 

 

The Compensation Committee approved modest 2021 merit-based base salary increases of 3.0% for each of Dr. McHutchison and Mr. Okazaki and 3.5% for Dr. Delaney, in recognition of our strong overall performance in 2020, notwithstanding the COVID-19 pandemic, including, among other accomplishments: completing our senior leadership transition, entering into collaborations with (1) BeiGene, Ltd., related to clinical development of our core inhibitors in the People’s Republic of China, Hong Kong, Taiwan and Macau, (2) Arbutus Biopharma Corporation to evaluate VBR + AB-720 + NrtI, and (3) Door Pharmaceuticals, LLC focused on developing a novel class of cccDNA disruptors to complement our current portfolio; completing a Phase 1a trial of 3733; and initiating a Phase 2 study of 2158.

In addition to his merit-based salary increase, Dr. Delaney’s salary was increased an additional 9.3% effective September 1, 2021 to bring his base salary more in line with Chief Scientific Officers at comparable companies, including members of our 2021 Peer Group, following a periodic market check conducted by Aon and our Human Resources team.

Annual Performance-Based Cash Bonus

Our employees, including our NEOs, are eligible to earn annual performance‑based cash bonuses to reward strong performance and encourage retention in a competitive labor market. We pay these bonuses to motivate and reward our employees for achieving or exceeding our shorter-term corporate goals, which are each designed to be measured over a calendar year.

Annual performance-based cash bonuses are earned based on the achievement of significant pre-set, objective Company-wide goals weighted to reflect their relative importance to the achievement of our goals, with specific goals tailored to the NEOs’ areas of responsibility. These performance goals are pre-set by our Compensation Committee in the first quarter of the applicable calendar year and approved by the Board. Actual bonus amounts earned are determined in the first quarter of the following year based on achievement of the pre-set Company-wide goals and, for employees other than our CEO, individual performance objectives set by our employees, including our NEOs other than the CEO, in consultation with their managers, which may include certain department, group or team objectives applicable to these employees. The Compensation Committee may increase or decrease an NEO’s bonus payment (above or below the target percentage) based on its assessment of our performance and that NEO’s individual performance during a given year. For 2021, annual bonuses were based on achievement of a broad variety of goals and included specific goals related to clinical development, research, manufacturing, financial operations,

business development and human resources. The selected goals were designed such that high rates of achievement overall required strong performances by all of our internal teams. Our 2021 corporate objectives, a statement regarding achievement, relative weight and achievement of each as of December 31, 2021 were as follows:

 

Total97%

We performed very strongly in 2021. Although our Development team fell short of achieving full enrollment of Study 203 and Study 204, this was largely due to COVID-19 pandemic-related patient screening delays, travel restrictions and hesitancy of patients to travel to study sites. In addition, certain of our Development team’s vendors were also impacted, as central laboratories were unable to meet contractual obligations, and other vendors experienced staffing constraints and supply chain challenges as they sought to obtain lab kits, reagents and other items necessary to enroll patients in Study 203 and Study 204.

Despite the Development team’s enrollment delays in 2021, after receiving and considering management’s analysis and recommendations, the Compensation Committee determined that the percentage achievement of the 2021 Company-wide performance goals was 97%. This determination of achievement for our 2021 corporate objectives despite the enrollment challenges experienced was supported by the strong performance of our Manufacturing, Business Development and Human Resources teams, which far exceeded the 2021 goals.

Our Manufacturing team’s performance resulted in greatly reduced costs to manufacture VBR and a more potent new formulation of 3733, which we plan to use in an upcoming Phase 1b study. Our Business Development team exceeded its target by completing a second strategic transaction, completing a sale of certain of our Microbiome

61

---

 

team’s assets, raising $3.0 million with a subsequent potential milestone payment. In addition to retaining all the critical talent throughout our organization, our management team, with significant support from Human Resources, kept our turnover rate below average for our industry.

In determining individual performance-based cash bonus payouts, the NEOs’ potential performance-based cash bonuses were weighted differently, depending on their respective areas of responsibility and contributions to our Company-wide goals.

Dr. McHutchison’s performance-based cash bonus was based exclusively on achievement of the Company-wide goals, which we outlined above. Our other NEOs’ performance-based cash bonuses were weighted 75% on achievement of the Company-wide goals and 25% on individual performance.

Mr. Okazaki’s individual performance was evaluated based on (1) his efforts in connection with the negotiation and execution of two business development transactions and (2) his performance overseeing our general and administrative functions of our business, including our investor relations, business development, legal and information technology teams.

Dr. Delaney’s individual performance was evaluated based on his efforts in connection with restructuring, building out and expanding the capacity and capabilities of our research organization.

Each of our employees, including our NEOs, is eligible for a target bonus, which is set as a percentage of annualized base salary. The Compensation Committee determines these target bonus percentages based on the range of target bonus percentages for similar positions in our peer group, and our Compensation Committee periodically reviews and evaluates our NEOs’ target bonus percentages as compared to our peers. None of the NEOs’ target bonus percentages, which are set forth in the table below, were changed between 2020 and 2021; however, effective August 1, 2021, Mr. Okazaki’s target bonus percentage was increased to 55% in connection with his promotion to Chief Operating Officer. The following table sets forth our NEOs’ 2021 target performance-based cash bonus amounts and actual performance-based cash bonuses earned.

 

 

Long-term Equity Incentive Awards

Our equity‑based long‑term incentive program is designed to align our employees’, including our NEOs’, long‑term incentives with those of our stockholders. In approving equity awards, the Compensation Committee’s and the Board’s guiding principles are to create a program that is designed to:

We believe that participation by our employees, including our NEOs, in our long-term equity incentive program is a critical factor in the achievement of long‑term Company-wide goals and business objectives. In furtherance of these objectives, equity awards granted to NEOs and other employees are a critical component of our compensation practices.

62

---

 

Annual Equity Grants

In 2021, our annual equity incentive awards consisted of a mix of stock options and time-based restricted stock units (RSUs), which is a common practice among the companies in our 2021 Peer Group. We believe stock options provide meaningful incentives to employees to achieve increases in the value of our stock over time, because employees profit from stock options only if our stock price increases relative to the stock option’s exercise price. We believe that RSU grants are also effective tools to retain and motivate our employees, including our NEOs, to achieve longer-term financial goals that we expect to lead to increased value to our stockholders while resulting in less dilution to our stockholders than stock options. In each case the interests of our employees and our stockholders are aligned; as our stock price increases, both our employees and our stockholders benefit.

Our Compensation Committee has previously discussed incorporating performance elements to our regular annual equity incentive program, however, based on discussions with Aon and the practices of our peer companies, the Compensation Committee decided that it is premature to introduce performance-based awards into our annual equity incentive program. We are a research and clinical stage biotechnology company that does not yet generate product revenues and satisfying the regulatory requirements of the U.S. Food and Drug Administration typically takes many years. Given our size, scope, the volatility of stock prices in our industry, as evidenced by the recent sustained downturn in the biotech market, and the long-term nature of our ultimate goals, Aon believes, and our Compensation Committee agrees, that time-based equity awards with meaningful time-based vesting periods have the same effect that performance-based awards have for differently situated companies. Inclusion of performance elements to our annual equity incentive program may not accurately reflect or reward our employees’ performance, including that of our NEOs. The Compensation Committee believes that the structure of our current long-term equity incentive program best aligns the interests of both our management and stockholders. Although the Compensation Committee thinks that it is premature to introduce performance-based awards into our regular annual equity incentive program, in 2021, the Compensation Committee implemented a broad-based supplemental equity award plan aimed at retaining our employees, which, for our NEOs, consisted of 100% performance-based RSUs. For more information, see “—Performance-Based Retention Equity Grants.”

Although the Compensation Committee has historically believed that in our industry, time-based vesting periods have the same effect that performance-based awards have for differently situated companies, the Compensation Committee has decided to use a mix of time- and performance-based RSUs in connection with our NEOs’ 2022 annual equity grants.

Grants of annual equity awards made to our executive officers, other than those to our CEO, are recommended by the CEO, considering input from Aon, and approved by the Compensation Committee. Grants of equity awards made to our CEO are discussed and determined by the Compensation Committee, in consultation with Aon, without the CEO present at any time.

The Compensation Committee considers the value of existing long-term equity incentive awards, internal pay equity considerations and individual and Company-wide performance when determining the size of annual equity grants. Annual stock option and RSU awards vest over four years, subject to continued service. In each case, we believe the applicable vesting schedule encourages long-term employment, while allowing our NEOs to realize compensation in line with the value that they have created for our stockholders. After considering these factors, in March 2021, our Compensation Committee approved the annual grants to our NEOs summarized in the table below.

 

Performance-Based Retention Equity Grants

As stated above, among the primary purposes of our equity-based long-term incentive program is to serve as a retention vehicle for our employees by motivating them to create long-term value that is shared by our stockholders.

63

---

 

In the first quarter of 2021, the Compensation Committee requested that Aon conduct an analysis of the retention value of our new-hire and annual equity awards granted over the previous several years. Aon’s analysis was performed using our stock price and outstanding stock options as of April 16, 2021. Due to the steep decline of our stock price in 2020 and 2021, our then-current 30-day average stock price of $4.49 per share, the average exercise price of our then-outstanding stock options was $13.63 per share. As a result, our outstanding stock options provided little to no retentive value as of early 2021. This negligible retention value, coupled with the highly active 2021 talent market fueled by the U.S. economy’s strong recovery from the COVID-19 pandemic, were the driving factors behind the Compensation Committee’s consideration of a broad-based supplemental equity award program.

Following a series of discussions with management and Aon regarding the proposed supplemental equity award program, the Committee recommended, and the Board approved, a framework as follows:

Sizes of individual supplemental equity awards were determined based on the criticality of the employee to receive the award and were targeted based on multiples of our annual equity award targets. C-Level awards, including those made to the NEOs, did not exceed 1.00x of our annual grant targets. As with our annual equity awards, grants of retention equity awards made to our CEO were discussed and determined by the Compensation Committee, in consultation with Aon, without the CEO present at any time.

The performance-based RSU awards vest in two installments: (1) 50% vest upon the later of (a) the first anniversary of the grant date and (b) the date on which the Compensation Committee determines that both performance milestones have been met (Milestone Vesting Date) and (2) 50% upon the first anniversary of the Milestone Vesting Date. The time-based supplemental equity awards vest in two installments, on the first and second anniversaries of the grant.

In July 2021, our Compensation Committee approved the supplemental equity awards to our NEOs summarized in the table below.

Other Compensation

In 2021, we maintained broad‑based benefits and perquisites that are provided to all eligible employees on the same terms, including 401(k) match, health insurance, life and disability insurance, dental insurance, sick leave and non-accrual vacation time.

Other Executive Compensation Policies

Sections 280G and 4999 of the Code

Sections 280G and 4999 of the Code provide that executive officers and directors who hold significant equity interests and certain other service providers may be subject to significant additional taxes if they receive payments or benefits in connection with a change in control that exceeds certain prescribed limits, and that we (or a successor) may forfeit a deduction on the amounts subject to this additional tax. We have not agreed to provide any executive officer with a “gross-up” or other reimbursement payment for any tax liability that the executive officer might owe because of the application of Sections 280G or 4999 of the Code.

Hedging and Pledging Policy

Under our Insider Trading Policy, all persons subject to the policy, including executive officers, directors, employees, consultants and contractors, are prohibited from engaging in the following transactions related to our securities:

Our Insider Trading Policy prohibits these types of transactions because there is both a heightened legal risk and the appearance of improper conduct if covered persons take part in transactions of this sort.

Compensation Risk Assessment

We believe that our executive compensation policies and programs do not encourage excessive or unnecessary risk taking. This is primarily because our compensation programs are designed to encourage our executive officers and other employees to focus on both short-term and long-term strategic goals. As a result, we do not believe that our compensation programs are reasonably likely to have a material adverse effect on us.

Clawback

The Compensation Committee has considered implementing a clawback policy several times. To date, we have no approved products on the market and have generated no product sales. As a result, our compensation-related goals are not tied to financial metrics and would not be affected by a restatement of our consolidated financial statements. However, given that the SEC reopened the comment period for the clawback rule contained in the Dodd-Frank Wall Street Reform and Consumer Protection Act, we expect that the SEC will issue final regulations soon, at which time we will implement an SEC-compliant clawback policy.

Stock Ownership Guidelines

The Compensation Committee most recently discussed the implementation of stock ownership guidelines in March 2022. The Compensation Committee noted the volatile nature of the biotech market, as evidenced by the recent steep declines of our stock price, and the well documented, sector-wide weakness in the biotech market that began in early 2021 and accelerated near the end of 2021. The Compensation Committee determined that the large number of shares that our executive officers would need to own to comply with any meaningful set of stock ownership guidelines makes it impracticable to implement stock ownership guidelines at that time. The Compensation Committee intends to review implementation of stock ownership guidelines and the impact that such guidelines may have periodically in the future.

Employment Arrangements

As of December 31, 2021, all our NEOs served pursuant to employment agreements. These agreements all share the following characteristics:

John G. McHutchison, A.O., M.D.

In August 2019, we entered into an employment agreement with Dr. McHutchison. The employment agreement provides for an at-will employment arrangement. Dr. McHutchison’s base salary in 2020 was $820,000 and his target bonus opportunity was 75% of his base salary. Effective February 16, 2021, Dr. McHutchison’s annualized base salary was increased to $844,600, and his target bonus opportunity remained unchanged.

We agreed to use our best efforts to cause Dr. McHutchison to be elected as a voting member of the Board throughout his employment and include him in the slate for election as a director at every stockholders’ meeting. Dr. McHutchison agreed to accept such election and to serve as a member of the Board without any additional compensation while he serves as our Chief Executive Officer.

If Dr. McHutchison’s employment is terminated due to his death other than during the period from one month prior to and through 12 months following, a change in control (as defined in his employment agreement), then we will pay to his estate his then-current base salary for a period of 12 months following such termination. However, if at the time of the Dr. McHutchison’s death, we provide or cause to be provided life insurance benefits for Dr. McHutchison at our sole expense, our obligation under the preceding sentence will be reduced to the extent of such life insurance coverage and will be fully satisfied if we maintain life insurance benefits for Dr. McHutchison equal to or greater than his then-current annualized base salary.

If Dr. McHutchison’s employment is terminated by us due to his disability (as defined in his employment agreement) or without cause (as defined in his employment agreement) or by Dr. McHutchison for good reason (as defined in his employment agreement) or as a result of his death, in each case during the period from one month prior to and through 12 months following, a change of control (as defined in his employment agreement), and subject to Dr. McHutchison’s execution and non-revocation of a general release of claims, we will provide Dr. McHutchison the following benefits: (1) a lump sum payment equal to 18 months of his then-current base salary; (2) an amount equal to 1.5 times his full target annual bonus for the year in which the termination occurred; (3) immediate vesting in full of all equity awards (including equity awards that vest based on performance but only to the extent accelerated vesting is provided in the agreements governing such equity awards); provided, however that (a) in the event that such termination occurs during the one month prior to a change of control, any equity-based compensation outstanding as of the termination will not accelerate but will remain outstanding and eligible to vest immediately prior to the consummation of the change of control and (b) in the event that such termination occurs prior to a change of control and such change of control is not consummated on or prior to the date one month after such termination, no vesting will occur and any equity awards outstanding as of the termination will vest, if at all, and terminate in accordance with, and to the extent provided in the non-change of control separation provisions and the equity award agreements; (4) extension of the exercise period for all vested stock options held by Dr. McHutchison to the end of their term; and (5) if Dr. McHutchison properly elects COBRA, reimbursement for the portion of the COBRA premiums that we would have paid had he remained employed for 18 months following termination or the end of his COBRA continuation period, whichever is earlier.

If Dr. McHutchison’s employment is terminated by us as a result of his disability, by us without cause or by Dr. McHutchison for good reason, and such termination does not occur during the one month prior to or within 12 months following, a change of control, and subject to Dr. McHutchison’s execution and non-revocation of a general release of claims, we will provide him the following benefits: (1) continued payment of his then-current base salary for 12 months following date of termination of employment; (2) his annual performance bonus, if any, for the year in which termination occurs in an amount equal to the amount Dr. McHutchison would have earned based on our

66

---

 

performance if he was employed for the full year, pro-rated based on the number of days employed for the year of termination; (3) all equity awards that would have time vested during the 12 months following the termination date shall accelerate and vest; (4) extension of the exercise period for all vested stock options held by Dr. McHutchison as of the termination date until the earlier of the first anniversary of the employment termination date and the termination date of the vested stock options; and (5) if Dr. McHutchison properly elects COBRA, reimbursement for the portion of the COBRA premiums that we would have paid had he remained employed for 12 months following termination or the end of his COBRA continuation period, whichever is earlier. The benefits described in this paragraph are in lieu of, and not in addition to, the benefits described in the prior preceding paragraph.

If the payments or benefits payable to Dr. McHutchison in connection with a change in control would be subject to the excise tax on golden parachutes imposed under Section 4999 of the Code, then those payments or benefits will be reduced if such reduction would result in a higher net after-tax benefit to Dr. McHutchison.

Jason A. Okazaki

In July 2021, we entered into an amended and restated agreement with Mr. Okazaki in connection with his promotion to Chief Operating Officer. Mr. Okazaki’s employment agreement provides for an initial annualized base salary of $540,000 and an annual performance-based incentive cash bonus in an amount initially targeted at 55% of Mr. Okazaki’s base salary.

If Mr. Okazaki’s employment is terminated by us as a result of his disability or without cause or by Mr. Okazaki for good reason within 12 months immediately following a change of control (as defined in his employment agreement), provided that Mr. Okazaki signs and does not revoke a general release of claims against us, we will provide him the following benefits: (1) a lump sum payment equal to 15 months of his then-current base salary; (2) an amount equal to his full target annual bonus for the year in which the termination occurred; (3) immediate vesting in full of all equity awards held by Mr. Okazaki that are subject to time-based vesting; and (4) if Mr. Okazaki properly elects COBRA, reimbursement of the portion of the COBRA premiums that we would have paid had he remained employed for 15 months following termination or the end of his COBRA continuation period, whichever is earlier; provided, however, our obligation to pay such premiums will terminate earlier if he becomes eligible for insurance benefits from another employer during such period.

If Mr. Okazaki’s employment is terminated as a result of his disability, by us without cause or by Mr. Okazaki for good reason, and such termination does not occur within 12 months following a change of control and provided that Mr. Okazaki signs and does not revoke a general release of claims against us, we will provide him the following benefits: (1) continued payment of his then-current base salary for 12 months following date of termination of employment, and (2) if Mr. Okazaki properly elects COBRA, reimbursement of the portion of the COBRA premiums that we would have paid had he remained employed for 12 months following termination or the end of his COBRA continuation period, whichever is earlier; provided, however, our obligation to pay such premiums will terminate earlier if he becomes eligible for insurance benefits from another employer during such period. Such benefits are in lieu of, and not in addition to, the benefits described in the preceding paragraph.

If the payments or benefits payable to Mr. Okazaki in connection with a change in control would be subject to the excise tax on golden parachutes imposed under Section 4999 of the Code, then those payments or benefits will be reduced if such reduction would result in a higher net after-tax benefit to Mr. Okazaki.

For a description of Mr. Okazaki’s severance entitlements under his employment agreement, see “—Severance and Change in Control Provisions” below.

William E. Delaney IV, Ph.D.

In May 2020, we entered into an employment agreement with Dr. Delaney. Dr. Delaney’s base salary in 2020 was $415,000 and his target bonus opportunity was 40% of his base salary. Effective February 16, 2021, Dr. Delaney’s annualized base salary was increased to $430,000, and his target bonus opportunity remained unchanged. Effective February 16, 2021, Dr. Delaney’s annualized base salary was increased to $470,000 to bring his base salary more in line with Chief Scientific Officers at comparable companies, and his target bonus opportunity remained unchanged.

If Dr. Delaney’s employment is terminated by us as a result of his disability or without cause or by Dr. Delaney for good reason within 12 months immediately following a change of control (as defined in his employment agreement),

67

provided that Dr. Delaney signs and does not revoke a general release of claims against us, we will provide him the following benefits: (1) a lump sum payment equal to 12 months of his then-current base salary; (2) an amount equal to his full target annual bonus for the year in which the termination occurred; (3) immediate vesting in full of all equity awards held by Dr. Delaney that are subject to time-based vesting; and (4) if Dr. Delaney properly elects COBRA, reimbursement of the portion of the COBRA premiums that we would have paid had he remained employed for 12 months following termination or the end of his COBRA continuation period, whichever is earlier; provided, however, our obligation to pay such premiums will terminate earlier if he becomes eligible for insurance benefits from another employer during such period.

If Dr. Delaney’s employment is terminated as a result of his disability, by us without cause or by Dr. Delaney for good reason, and such termination does not occur within 12 months following a change of control and provided that Dr. Delaney signs and does not revoke a general release of claims against us, we will provide him the following benefits: (1) continued payment of his then-current base salary for 12 months following date of termination of employment, and (2) if Dr. Delaney properly elects COBRA, reimbursement of the portion of the COBRA premiums that we would have paid had he remained employed for 12 months following termination or the end of his COBRA continuation period, whichever is earlier; provided, however, our obligation to pay such premiums will terminate earlier if he becomes eligible for insurance benefits from another employer during such period. Such benefits are in lieu of, and not in addition to, the benefits described in the preceding paragraph.

If the payments or benefits payable to Dr. Delaney in connection with a change in control would be subject to the excise tax on golden parachutes imposed under Section 4999 of the Code, then those payments or benefits will be reduced if such reduction would result in a higher net after-tax benefit to the NEO.

Certain Relationships and Related Party Transactions

The written charter of our Audit Committee authorizes our Audit Committee to review and approve related party transactions. In reviewing related party transactions, our Audit Committee applies the basic standard that transactions with affiliates should be made on terms no less favorable to us than could have been obtained from unaffiliated parties. Therefore, the Audit Committee reviews the benefits of the transactions, terms of the transactions and the terms available from unrelated third parties, as applicable. All transactions other than compensatory arrangements between us and our officers, directors, principal stockholders and their affiliates will be approved or ratified by our Audit Committee or a majority of the disinterested directors only on terms no less favorable to us than could be obtained from unaffiliated third parties.

In September 2019, we retained Colin Watanabe as a consultant to provide critical bioinformatic support for intellectual property filings made by our Microbiome program, which was wound down in January 2021. Dr. Watanabe shares a common household with, and is the significant other of, Jacqueline Papkoff, our former Chief Scientific Officer – Microbiome. Dr. Watanabe retired in March 2019 following a 40-year career building a bioinformatics programming infrastructure at a large pharmaceutical company, and we retained him in connection with the resignation of our then-only bioinformatics employee. Dr. Watanabe initially backfilled the role of the departed employee and participated in the screening of bioinformatics candidates. Upon the completion of the restaffing of the bioinformatics team, Dr. Watanabe dedicated his time to rebuilding our bioinformatics infrastructure and workflows, as well as building new databases that enabled new types of bioinformatics sequence analyses that greatly improved taxonomic classification, which was critical to our Microbiome program’s intellectual property efforts. Since Dr. Watanabe is retired, he was not seeking full-time employment and worked only ten hours per week between September 2019 and the end of his engagement in December 2020. In 2020, we paid Dr. Watanabe approximately $135,000, which includes a 17.5% markup paid to a third-party management company.

Other than the above transaction and the compensation agreements and other arrangements described under “Executive Compensation—Employment Arrangements,” since January 1, 2020, there has not been and there is not currently proposed, any transaction or series of similar transactions to which we were, or will be, a party in which the amount involved exceeded, or will exceed, $120,000 and in which any director, executive officer, holder of five percent or more of any class of our capital stock or any member of the immediate family of, or entities affiliated with, any of the foregoing persons, had, or will have, a direct or indirect material interest.

Stock Ownership Information

Security Ownership of Certain Beneficial Owners

The following table sets forth certain information regarding the ownership of shares of our common stock based on 48,120,437 shares outstanding as of March 28, 2022, the record date for the Annual Meeting, by (1) each person known by us to beneficially own more than 5% of the outstanding shares of common stock, (2) each of our directors and (3) each of our NEOs and (4) all of our directors and current executive officers as a group.

This table is based upon information supplied by our directors and NEOs and from Schedules 13G filed with the SEC by our 5% stockholder. Unless otherwise indicated in the footnotes to this table and subject to community property laws where applicable, each of the stockholders named in this table has sole voting and investment power with respect to the shares indicated as beneficially owned by them. Share ownership in each case includes (1) shares issuable upon exercise of options and warrants that may be exercised within 60 days after the record date and (2) RSUs held by the individual that are scheduled to vest and settle within 60 days after the record date for purposes of computing the percentage of common stock owned by such person, but not for purposes of computing the percentage owned by any other person. Unless otherwise noted, the address for each person listed below is c/o Assembly Biosciences, Inc., 331 Oyster Point Blvd., Fourth Floor, South San Francisco, California 94080. Applicable percentages are based on 48,120,437 shares outstanding on the record date.

There are no arrangements known to us, including any pledge by any person of our securities, the operation of which may at a subsequent date result in a change in control of Assembly.

Delinquent Section 16(a) Reports

Section 16(a) of the Exchange Act, requires our executive officers, directors, and “beneficial owners” of more than 10% of our common stock to file stock ownership reports and reports of changes in ownership with the SEC. Based on a review of those reports and written representations from the reporting persons, we believe that during fiscal 2021, all transactions were reported on a timely basis except that, due to an administrative oversight, a Form 4 by Dr. McHutchison reporting an annual equity grant and Form 4s by Mr. Okazaki, Dr. Delaney, Luisa M. Stamm, M.D., Ph.D. and Thomas J. Russo, our former Chief Financial Officer, each reporting two annual equity grants that were due on March 31, 2021 were filed on April 2, 2021.

To be considered for inclusion in next year’s proxy materials, any proposals must be submitted in writing by December 13, 2022, to our Corporate Secretary at 331 Oyster Point Blvd., Fourth Floor, South San Francisco, California 94080; provided, however, that if our 2023 Annual Meeting of Stockholders is held before April 25, 2023 or after June 24, 2023, then the deadline is a reasonable amount of time prior to the date we begin to print and send our proxy statement for the 2023 Annual Meeting of Stockholders.

Subject to compliance with applicable requirements of state law and the Exchange Act, our Amended and Restated Bylaws also provide for separate notice procedures to propose business to be considered by stockholders at a meeting. Such proposals must comply with the requirements, including without limitation, the separate notice procedures, of our Amended and Restated Bylaws. If you wish to submit such a proposal, written notice must be received by the Corporate Secretary no later than the close of business not more than 90 days before or less than 60 days before the date of the meeting, in the case of the 2023 Annual Meeting of Stockholders or any other annual meeting, or by the tenth business day following the day on which public announcement of the date of the meeting is first made, in the case of a special meeting.

Our Amended and Restated Bylaws permit a stockholder, or a group of up to 20 eligible stockholders, that has owned at least 3% of our outstanding common stock for at least three years to nominate and include in our proxy statement candidates for the Board, subject to certain requirements. Any such nomination must be received at the address above no earlier than the close of business on November 13, 2022 and no later than the close of business on December 13, 2022; provided, however, that if our 2023 Annual Meeting of Stockholders is held before April 25, 2023 or after June 24, 2023, then the deadline is the later of close of business on the date that is 180 days prior to the 2023 Annual Meeting of Stockholders and the tenth day following the date that the 2023 Annual Meeting of Stockholders is first publicly disclosed.

Delivery of Documents to Stockholders Sharing an Address

The SEC has adopted rules that permit companies to deliver a single Proxy Availability Notice or a single copy of proxy materials to multiple stockholders sharing an address unless a company has received contrary instructions from one or more of the stockholders at that address. Upon request, we will promptly deliver a separate Proxy Availability Notice or separate copy of proxy materials to one or more stockholders at a shared address to which a single Proxy Availability Notice or a single copy of proxy materials was delivered. Stockholders may request a separate Proxy Availability Notice or separate copy of proxy materials by contacting our Corporate Secretary either by calling +1.833.509.4583 or by mailing a request to 331 Oyster Point Blvd., Fourth Floor, South San Francisco, California 94080. Stockholders at a shared address who receive multiple Proxy Availability Notices or multiple copies of proxy materials may request to receive a single Proxy Availability Notice or a single copy of proxy materials in the future in the same manner as described above.

Other Matters

The Board knows of no business to be brought before the meeting other than the proposals identified in this proxy statement. If any other matters properly come before the stockholders at the Annual Meeting, it is the intention of the persons named on the proxy to vote the shares represented thereby in accordance with their best judgment.

(iii)         In the absence of an established market for the Common Stock of the type described in (i) and (ii), above, the Fair Market Value thereof shall be determined by the Administrator in a manner in compliance with Section 409A of the Code, and in the case of an Incentive Stock Option, in a manner in compliance with Section 422 of the Code.

Shares that actually have been issued under the Plan pursuant to an Award shall not be returned to the Plan and shall not become available for future issuance under the Plan, except that if Options or other Awards granted under this Plan are forfeited or repurchased by the Company, such Shares shall become available for future grant under the Plan.

4.            Administration of the Plan.

(a)          Plan Administrator.

(i)           Administration with Respect to Directors and Officers. With respect to grants of Awards to Directors or Employees who are also Officers or Directors of the Company, the Plan shall be administered by (A) the Board or (B) a Committee designated by the Board, which Committee shall be constituted in such a manner as to satisfy the Applicable Laws and to permit such grants and related transactions under the Plan to be exempt from Section 16(b) of the Exchange Act in accordance with Rule 16b-3. Once appointed, such Committee shall continue to serve in its designated capacity until otherwise directed by the Board.

(ii)          Administration With Respect to Consultants and Other Employees. With respect to grants of Awards to Employees or Consultants who are neither Directors nor Officers of the Company, the Plan shall be administered by (A) the Board or (B) a Committee designated by the Board, which Committee shall be constituted in such a manner as to satisfy the Applicable Laws. Once appointed, such Committee shall continue to serve in its designated capacity until otherwise directed by the Board.

(vii)        to amend the terms of any outstanding Award granted under the Plan, provided that any amendment that would adversely affect the Grantee’s rights under an outstanding Award shall not be made without the Grantee’s written consent; provided, however, that an amendment or modification that may cause an Incentive Stock Option to become a Non-Qualified Stock Option shall not be treated as adversely affecting the rights of the Grantee;

(viii)       to construe and interpret the terms of the Plan and Awards, including without limitation, any notice of award or Award Agreement, granted pursuant to the Plan;

(ix)         to institute an option exchange program; and

(x)          to take such other action, not inconsistent with the terms of the Plan, as the Administrator deems appropriate.

The express grant in the Plan of any specific power to the Administrator shall not be construed as limiting any power or authority of the Administrator; provided that the Administrator may not exercise any right or power reserved to the Board. Any decision made, or action taken, by the Administrator or in connection with the administration of this Plan shall be final, conclusive and binding on all persons having an interest in the Plan.

(d)          Indemnification. In addition to such other rights of indemnification as they may have as members of the Board or as Officers or Employees of the Company or a Related Entity, members of the Board and any Officers or Employees of the Company or a Related Entity to whom authority to act for the Board, the Administrator or the Company is delegated shall be defended and indemnified by the Company to the extent permitted by law on an after-tax basis against all reasonable expenses, including attorneys’ fees, actually and necessarily incurred in connection with the defense of any claim, investigation, action, suit or proceeding, or in connection with any appeal therein, to which they or any of them may be a party by reason of any action taken or failure to act under or in connection with the Plan, or any Award granted hereunder, and against all amounts paid by them in settlement thereof (provided such settlement is approved by the Company) or paid by them in satisfaction of a judgment in any such claim, investigation, action, suit or proceeding, except in relation to matters as to which it shall be adjudged in such claim, investigation, action, suit or proceeding that such person is liable for gross negligence, bad faith or intentional misconduct; provided, however, that within thirty (30) days after the institution of such claim, investigation, action, suit or proceeding, such person shall offer to the Company, in writing, the opportunity at the Company’s expense to defend the same.

5.            Eligibility. Awards other than Incentive Stock Options may be granted to Employees, Directors and Consultants of the Company and any Related Entity. Incentive Stock Options may be granted only to Employees of the Company or a Parent or a Subsidiary of the Company.

Awards may be granted to such Employees, Directors or Consultants who are residing in non-U.S. jurisdictions as the Administrator may determine from time to time.

6.            Terms and Conditions of Awards.

(a)          Types of Awards.

(b)          Designation of Award. Each Award shall be designated in the Award Agreement. In the case of an Option, the Option shall be designated as either an Incentive Stock Option or a Non-Qualified Stock Option. However, notwithstanding such designation, an Option will qualify as an Incentive Stock Option under the Code only to the extent the $100,000 dollar limitation of Section 422(d) of the Code is not exceeded. The $100,000 limitation of Section 422(d) of the Code is calculated based on the aggregate Fair Market Value of the Shares subject to Options designated as Incentive Stock Options which become exercisable for the first time by a Grantee during any calendar year (under all plans of the Company or any Parent or Subsidiary of the Company). For purposes of this calculation, Incentive Stock Options shall be taken into account in the order in which they were granted, and the Fair Market Value of the Shares shall be determined as of the grant date of the relevant Option.

(c)           Conditions of Award. Subject to the terms of the Plan, the Administrator shall determine the provisions, terms, and conditions of each Award including, but not limited to, the Award vesting schedule, repurchase provisions, rights of first refusal, forfeiture provisions, form of payment (cash, Shares, or other consideration) upon settlement of the Award, payment contingencies, and satisfaction of any performance criteria. The performance criteria established by the Administrator may be based on any one of, or combination of, increase in share price, earnings per share, total stockholder return, return on equity, return on assets, return on investment, net operating income, cash flow, revenue, economic value added, initiation or completion of clinical trials, results of clinical trials, regulatory approval, regulatory submissions, drug development or commercialization milestones, collaboration milestones or strategic partnerships. Partial achievement of the specified criteria may result in a payment or vesting corresponding to the degree of achievement as specified in the Award Agreement.

(d)          Acquisitions and Other Transactions. The Administrator may issue Awards under the Plan in settlement, assumption or substitution for, outstanding awards or obligations to grant future awards in connection with the Company or a Related Entity acquiring another entity, an interest in another entity or an additional interest in a Related Entity whether by merger, stock purchase, asset purchase or other form of transaction.

(e)          Deferral of Award Payment. The Administrator may establish one or more programs under the Plan to permit selected Grantees the opportunity to elect to defer receipt of consideration upon exercise of an Award, satisfaction of performance criteria, or other event that absent the election would entitle the Grantee to payment or receipt of Shares or other consideration under an Award. The Administrator may establish the election procedures, the timing of such elections, the mechanisms for payments of, and accrual of interest or other earnings, if any, on amounts, Shares or other consideration so deferred, and such other terms, conditions, rules and procedures that the Administrator deems advisable for the administration of any such deferral program.

(f)           Separate Programs. The Administrator may establish one or more separate programs under the Plan for the purpose of issuing particular forms of Awards to one or more classes of Grantees on such terms and conditions as determined by the Administrator from time to time.

(g)          Early Exercise. The Award Agreement may, but need not, include a provision whereby the Grantee may elect at any time while an Employee, Director or Consultant to exercise any part or all of the Award prior to full vesting of the Award. Any unvested Shares received pursuant to such exercise may be subject to a repurchase right in favor of the Company or a Related Entity or to any other restriction the Administrator determines to be appropriate.

(h)          Term of Option or SAR. The term of each Option or SAR shall be the term stated in the Award Agreement, provided, however, that the term shall be no more than ten (10) years from the date of grant thereof. However, in the case of an Incentive Stock Option granted to a Grantee who, at the time the Option is granted, owns stock representing more than ten percent (10%) of the voting power of all classes of stock of the Company or any Parent or Subsidiary of the Company, the term of the Incentive Stock Option shall be five (5) years from the date of grant thereof or such shorter term as may be provided in the Award Agreement.

(i)           Transferability of Awards. Unless the Administrator provides otherwise, in its sole discretion, no Award may be sold, pledged, assigned, hypothecated, transferred, or disposed of in any manner other than by will or by the laws of descent or distribution and may be exercised, during the lifetime of the Grantee, only by the Grantee. Notwithstanding the foregoing, the Grantee may designate one or more beneficiaries of the Grantee’s Award in the event of the Grantee’s death on a beneficiary designation form provided by the Administrator.

(j)           Time of Granting Awards. The date of grant of an Award shall for all purposes be the date on which the Administrator makes the determination to grant such Award, or such other later date as is determined by the Administrator.

(k)          Stock Appreciation Rights. An SAR may be granted (i) with respect to any Option granted under this Plan, either concurrently with the grant of such Option or at such later time as determined by the Administrator (as to all or any portion of the shares of Common Stock subject to the Option), or (ii) alone, without reference to any related Option. Each SAR granted by the Administrator under this Plan shall be subject to the following terms and conditions. Each SAR granted to any participant shall relate to such number of shares of Common Stock as shall be determined by the Administrator, subject to adjustment as provided in Section 12. In the case of an SAR granted with respect to an Option, the number of shares of Common Stock to which the SAR pertains shall be reduced in the same proportion that the holder of the Option exercises the related Option. The exercise price of an SAR will be determined by the Administrator, in its discretion, at the date of grant but may not be less than one hundred percent (100%) of the Fair Market Value of the shares of Common Stock subject thereto on the date of grant. Subject to the right of the Administrator to deliver cash in lieu of shares of Common Stock (which, as it pertains to Officers and Directors of the Company, shall comply with all requirements of the Exchange Act), the number of shares of Common Stock which shall be issuable upon the exercise of an SAR shall be determined by dividing:

(i)           the number of shares of Common Stock as to which the SAR is exercised multiplied by the amount of the appreciation in such shares (for this purpose, the “appreciation” shall be the amount by which the Fair Market Value of the shares of Common Stock subject to the SAR on the exercise date exceeds (1) in the case of an SAR related to an Option, the exercise price of the shares of Common Stock under the Option or (2) in the case of an SAR granted alone, without reference to a related Option, an amount which shall be determined by the Administrator at the time of grant, subject to adjustment under Section 12); by

(ii)          the Fair Market Value of a share of Common Stock on the exercise date.

In lieu of issuing shares of Common Stock upon the exercise of an SAR, the Administrator may elect to pay the holder of the SAR cash equal to the Fair Market Value on the exercise date of any or all of the shares which would otherwise be issuable. No fractional shares of Common Stock shall be issued upon the exercise of an SAR; instead, the holder of the SAR shall be entitled to receive a cash adjustment equal to the same fraction of the Fair Market Value of a share of Common Stock on the exercise date or to purchase the portion necessary to make a whole share at its Fair Market Value on the date of exercise. The exercise of an SAR related to an Option shall be permitted only to the extent that the Option is exercisable under Section 10 on the date of surrender. Any Incentive Stock Option surrendered pursuant to the provisions of this Section 6(k) shall be deemed to have been converted into a Non-Qualified Stock Option immediately prior to such surrender.

(l)           Compliance with Section 409A of the Code. Notwithstanding anything to the contrary set forth herein, any Award that is not exempt from the requirements of Section 409A of the Code shall contain such provisions so that such Award will comply with the requirements of Section 409A of the Code. Such restrictions, if any, shall be determined by the Administrator and contained in the Award Agreement evidencing such Award.

(m)         Minimum Vesting. Awards granted to Employees under the Plan that are subject to time vesting shall not vest or become exercisable until at least one year after the date of grant, except in the case of death, Disability, retirement, separation of service or a Corporate Transaction. Awards granted to Directors under the Plan that are subject to time vesting shall not vest or become exercisable until at least the earlier of (i) one year after the date of grant or (ii) the next annual meeting of stockholders, except in the case of death, Disability or a Corporate Transaction.

7.            Award Exercise or Purchase Price, Consideration and Taxes.

(a)          Exercise or Purchase Price. The exercise or purchase price, if any, for an Award shall be as follows.

(i)           In the case of an Incentive Stock Option:

(1)          granted to an Employee who, at the time of the grant of such Incentive Stock Option owns stock representing more than ten percent (10%) of the voting power of all classes of stock of the Company or any Parent or Subsidiary of the Company, the per Share exercise price shall be not less than one hundred ten percent (110%) of the Fair Market Value per Share on the date of grant; or

(2)          granted to any Employee other than an Employee described in the preceding paragraph, the per Share exercise price shall be not less than one hundred percent (100%) of the Fair Market Value per Share on the date of grant.

(ii)          In the case of a Non-Qualified Stock Option, the per Share exercise price shall be not less than one-hundred percent (100%) of the Fair Market Value per Share on the date of grant.

(iii)         In the case of other Awards, such price as is determined by the Administrator.

(iv)         Notwithstanding the foregoing provisions of this Section 7(a), in the case of an Award issued pursuant to Section 6(d), above, the exercise or purchase price for the Award shall be determined in accordance with the provisions of the relevant instrument evidencing the agreement to issue such Award.

(b)          Consideration. Subject to Applicable Laws, the consideration to be paid for the Shares to be issued upon exercise or purchase of an Option or upon the issuance of another Award, including the method of payment, shall be determined by the Administrator. In addition to any other types of consideration the Administrator may determine, the Administrator is authorized to accept as consideration for Shares issued under the Plan the following:

(i)           cash;

(ii)          check;

(iii)         delivery of Grantee’s promissory note with such recourse, interest, security, and redemption provisions as the Administrator determines as appropriate (but only to the extent that the acceptance or terms of the promissory note would not violate an Applicable Law); provided, however, that interest shall compound at least annually and shall be charged at the minimum rate of interest necessary to avoid (i) the imputation of interest income to the Company and compensation income to the Grantee under any applicable provisions of the Code, and (B) the classification of the Award as a liability for financial accounting purposes;

(iv)         surrender of Shares or delivery of a properly executed form of attestation of ownership of Shares as the Administrator may require which have a Fair Market Value on the date of surrender or attestation equal to the aggregate exercise price of the Shares as to which said Award shall be exercised;

(v)          payment through a broker-dealer sale and remittance procedure pursuant to which the Grantee (A) shall provide written instructions to a Company designated brokerage firm to effect the immediate sale of some or all of the purchased Shares and remit to the Company sufficient funds to cover the aggregate exercise price payable for the purchased Shares and (B) shall provide written directives to the Company to deliver the certificates (or other evidence satisfactory to the Company to the extent that the Shares are uncertificated) for the purchased Shares directly to such brokerage firm in order to complete the sale transaction;

(vi)         with respect to Non-Qualified Options, payment through a “net exercise” such that, without the payment of any funds, the Grantee may exercise the Option and receive the net number of Shares equal to (i) the number of Shares as to which the Option is being exercised, multiplied by (ii) a fraction, the numerator of which is the Fair Market Value per Share (on such date as is determined by the Administrator) less the Exercise Price per Share, and the denominator of which is such Fair Market Value per Share; or

B-9

---

 

(vii)        past or future services actually or to be rendered to the Company or a Related Entity; or

(viii)       any combination of the foregoing methods of payment.

The Administrator may at any time or from time to time, by adoption of or by amendment to the standard forms of Award Agreement described in Section 4(c)(iv), or by other means, grant Awards which do not permit all of the foregoing forms of consideration to be used in payment for the Shares or which otherwise restrict one or more forms of consideration.

8.            Notice to Company of Disqualifying Disposition. Each Employee who receives an Incentive Stock Option must agree to notify the Company in writing immediately after the Employee makes a Disqualifying Disposition of any Common Stock acquired pursuant to the exercise of an Incentive Stock Option.

9.            Withholding of Additional Income Taxes.

(a)           Upon the exercise of a Non-Qualified Stock Option or SAR, the grant of any other Award for less than the Fair Market Value of the Common Stock, the grant of Unrestricted Stock or the vesting of restricted Common Stock acquired on the exercise of an Award hereunder, the Company, in accordance with Section 3402(a) of the Code and any applicable state statute or regulation, may require the Grantee to pay to the Company additional withholding taxes in respect of the amount that is considered compensation includable in such person’s gross income. With respect to (i) the exercise of an Option, (ii) the grant of Unrestricted Stock, (iii) the grant of any other Award for less than its Fair Market Value, (iv) the vesting of restricted Common Stock acquired by exercising an Award, or (v) the exercise of an SAR, the Committee in its discretion may condition such event on the payment by the Grantee of any such additional withholding taxes.

(b)          At the sole and absolute discretion of the Administrator, the holder of Awards may pay all or any part of the total estimated federal and state income tax liability arising out of the exercise or receipt of such Awards or the vesting of restricted Common Stock acquired on the exercise of an Award hereunder (each of the foregoing, a “Tax Event”) by tendering already-owned shares of Common Stock or by directing the Company to withhold shares of Common Stock otherwise to be transferred to the Grantee as a result of the exercise or receipt thereof in an amount equal to the estimated federal and state income tax liability arising out of such event, provided that no more Shares may be withheld than are necessary to satisfy the Grantee’s withholding obligation with respect to the exercise of Awards; provided, however, that the amount withheld does not exceed the maximum statutory tax rate or such lesser amount as is necessary to avoid liability accounting treatment for Awards granted under the Plan. In such event, the Grantee must, however, notify the Administrator of his or her desire to pay all or any part of the total estimated federal and state income tax liability arising out of a Tax Event by tendering already-owned shares of Common Stock or having shares of Common Stock withheld prior to the date that the amount of federal or state income tax to be withheld is to be determined. For purposes of this Section 9, shares of Common Stock shall be valued at their Fair Market Value on the date that the amount of the tax withholdings is to be determined.

10.          Exercise of Award.

(a)          Procedure for Exercise; Rights as a Stockholder.

(i)           Any Award granted hereunder shall be exercisable at such times and under such conditions as determined by the Administrator under the terms of the Plan and specified in the Award Agreement.

(ii)          An Award shall be deemed to be exercised when written notice of such exercise has been given to the Company in accordance with the terms of the Award by the person entitled to exercise the Award and full payment for the Shares with respect to which the Award is exercised has been made, including, to the extent selected, use of the broker-dealer sale and remittance procedure to pay the purchase price as provided in Section 7(b)(v).

(b)          Exercise of Award Following Termination of Continuous Service. In the event of termination of a Grantee’s Continuous Service for any reason other than Disability or death (but not in the event of a Grantee’s change of status from Employee to Consultant or from Consultant to Employee), such Grantee may, but only during the Post-Termination Exercise Period (but in no event later than the expiration date of the term of such Award as set forth in the Award Agreement), exercise the portion of the Grantee’s Award that was vested at the date of such termination or such other portion of the Grantee’s Award as may be determined by the Administrator. The Grantee’s Award Agreement may provide that upon the termination of the Grantee’s Continuous Service for Cause, the Grantee’s right to exercise the Award shall terminate concurrently with the termination of Grantee’s Continuous Service. In the event of a Grantee’s change of status from Employee to Consultant, an Employee’s Incentive Stock Option shall convert automatically to a Non-Qualified Stock Option on the day three (3) months and one (1) day following such change of status. To the extent that the Grantee’s Award was unvested at the date of termination, or if the Grantee does not exercise the vested portion of the Grantee’s Award within the Post-Termination Exercise Period, the Award shall terminate.

(c)          Disability of Grantee. In the event of termination of a Grantee’s Continuous Service as a result of his or her Disability, such Grantee may, but only within twelve (12) months from the date of such termination (or such longer period as specified in the Award Agreement but in no event later than the expiration date of the term of such Award as set forth in the Award Agreement), exercise the portion of the Grantee’s Award that was vested at the date of such termination; provided, however, that if such Disability is not a “disability” as such term is defined in Section 22(e)(3) of the Code, in the case of an Incentive Stock Option such Incentive Stock Option shall automatically convert to a Non-Qualified Stock Option on the day three (3) months and one (1) day following such termination. To the extent that the Grantee’s Award was unvested at the date of termination, or if Grantee does not exercise the vested portion of the Grantee’s Award within the time specified herein, the Award shall terminate.

(d)          Death of Grantee. In the event of a termination of the Grantee’s Continuous Service as a result of his or her death, or in the event of the death of the Grantee during the Post-Termination Exercise Period or during the twelve (12) month period following the Grantee’s termination of Continuous Service as a result of his or her Disability, the Grantee’s estate or a person who acquired the right to exercise the Award by bequest or inheritance may exercise the portion of the Grantee’s Award that was vested as of the date of termination, within twelve (12) months from the date of death (or such longer period as specified in the Award Agreement but in no event later than the expiration of the term of such Award as set forth in the Award Agreement). To the extent that, at the time of death, the Grantee’s Award was unvested, or if the Grantee’s estate or a person who acquired the right to exercise the Award by bequest or inheritance does not exercise the vested portion of the Grantee’s Award within the time specified herein, the Award shall terminate.

(e)          Extension if Exercise Prevented by Law. Notwithstanding the foregoing, if the exercise of an Award within the applicable time periods set forth in this Section 10 is prevented by the provisions of Section 11 below, the Award shall remain exercisable until one (1) month after the date the Grantee is notified by the Company that the Award is exercisable, but in any event no later than the expiration of the term of such Award as set forth in the Award Agreement.

11.          Conditions Upon Issuance of Shares.

(a)          If at any time the Administrator determines that the delivery of Shares pursuant to the exercise, vesting or any other provision of an Award is or may be unlawful under Applicable Laws, the vesting or right to exercise an Award or to otherwise receive Shares pursuant to the terms of an Award shall be suspended until the Administrator determines that such delivery is lawful and shall be further subject to the approval of counsel for the Company with respect to such compliance. The Company shall have no obligation to effect any registration or qualification of the Shares under federal or state laws.

(b)          As a condition to the exercise of an Award, the Company may require the person exercising such Award to represent and warrant at the time of any such exercise that the Shares are being purchased only for investment and without any present intention to sell or distribute such Shares if, in the opinion of counsel for the Company, such a representation is required by any Applicable Laws.

12.          Adjustments. Subject to any required action by the stockholders of the Company, the number of Shares covered by each outstanding Award, and the number of Shares which have been authorized for issuance under the Plan but as to which no Awards have yet been granted or which have been returned to the Plan, the exercise or purchase price of each such outstanding Award, as well as any other terms that the Administrator determines require adjustment shall be proportionately adjusted for (i) any increase or decrease in the number of issued Shares resulting from a stock split, reverse stock split, stock dividend, combination or reclassification of the Shares, or similar transaction affecting the Shares, (ii) any other increase or decrease in the number of issued Shares effected without receipt of consideration by the Company, or (iii) any other transaction with respect to the Company’s Common Stock including a corporate merger, consolidation, acquisition of property or stock, separation (including a spin-off or other distribution of stock or property), reorganization, liquidation (whether partial or complete) or any similar transaction; provided, however that conversion of any convertible securities of the Company shall not be deemed to have been “effected without receipt of consideration.” Such adjustment shall be made by the Administrator and its determination shall be final, binding and conclusive. Except as the Administrator determines, no issuance by the Company of shares of stock of any class, or securities convertible into shares of stock of any class, shall affect, and no adjustment by reason hereof shall be made with respect to, the number or price of Shares subject to an Award. No adjustments shall be made for dividends paid in cash or in property other than Common Stock of the Company, nor shall cash dividends or dividend equivalents accrue or be paid in respect of unexercised Options or unvested Awards hereunder.

13.          Corporate Transactions.

(a)          Treatment of Awards in Corporate Transaction. Except as the Administrator may otherwise specify with respect to particular Awards in the relevant Award Agreement, in the case of and subject to the consummation of a Corporate Transaction, the parties to the Corporate Transaction may cause the Awards to be Assumed or Replaced by the successor entity as such parties shall agree. To the extent the parties to such Corporate Transaction do not provide for the Awards to be Assumed or Replaced upon the effective time of the Corporate Transaction, the Plan and all outstanding Awards granted under the Plan shall terminate. In such case, except as may be otherwise expressly provided in the relevant Award Agreement, all Awards with solely time-based vesting that are not vested and/or exercisable immediately prior to the effective time of the Corporate Transaction shall become fully vested and exercisable as of immediately prior to the effective time of the Corporate Transaction and all Awards with conditions and restrictions relating to the attainment of performance goals shall be deemed to vest and become nonforfeitable as of the Corporate Transaction as provided in the relevant Award Agreement or if not provided for in the relevant Award Agreement shall be deemed to vest and become nonforfeitable as of the Corporate Transaction assuming the higher of (i) achievement of all relevant performance goals at the "target" level (prorated based upon the length of time within the performance period that has elapsed prior the Corporate Transaction or partial achievement of the performance goals), or (ii) actual achievement of all relevant performance goals as of the date of such Corporate Transaction. In the event of such termination of the Awards, the Company shall have the option (in its sole discretion) to (1) make or provide for a payment, in cash or in kind, to the Grantees holding Options and SARs, in exchange for the cancellation thereof, in an amount equal to the difference between (A) the Sale Price multiplied by the number of Shares subject to outstanding Options and SARs and (B) the aggregate exercise price of all such outstanding Options and SARs (provided that, in the case of an Option or SAR with an exercise price equal to or more than the Sale Price, such Option or SAR shall be cancelled for no consideration); or (2) permit each Grantee, within a specified period of time prior to the consummation of the Corporate Transaction as determined by the Administrator, to exercise all outstanding Options and SARs (to the extent then exercisable including due to acceleration as contemplated by this Section 13(a) if the Awards are not Assumed or Replaced) held by such Grantee as of immediately prior to the effective time of the Corporate Transaction. In the event of a termination of Awards pursuant to this Section 13(a), the Company shall also have the option (in its sole discretion) to make or provide for a payment, in cash or in kind, to the Grantees holding other Awards in an amount equal to the Sale Price multiplied by the number of vested Shares under such Awards.  For purposes of this Section 13(a), “Sale Price” means the value as determined by the Administrator of the consideration payable, or otherwise to be received by stockholders, per Share pursuant to a Corporate Transaction.

B-12

---

 

(b)          Acceleration of Award Upon Corporate Transaction. The Administrator shall have the authority, exercisable either in advance of any actual or anticipated Corporate Transaction or at the time of an actual Corporate Transaction and exercisable at the time of the grant of an Award under the Plan or any time while an Award remains outstanding, to provide for the full or partial automatic vesting and exercisability of one or more outstanding unvested Awards under the Plan and the release from restrictions on transfer and repurchase or forfeiture rights of such Awards in connection with a Corporate Transaction on such terms and conditions as the Administrator may specify. The Administrator also shall have the authority to condition any such Award vesting and exercisability or release from such limitations upon the subsequent termination of the Continuous Service of the Grantee within a specified period following the effective date of the Corporate Transaction. The Administrator may provide that any Awards so vested or released from such limitations in connection with a Corporate Transaction shall remain fully exercisable until the expiration or sooner termination of the Award.

(c)          Effect of Acceleration on Incentive Stock Options. Any Incentive Stock Option accelerated under this Section 13 in connection with a Corporate Transaction shall remain exercisable as an Incentive Stock Option under the Code only to the extent the $100,000 dollar limitation of Section 422(d) of the Code is not exceeded.

14.          Effective Date and Term of Plan. The Plan shall become effective upon the earlier to occur of its adoption by the Board or its approval by the stockholders of the Company. It shall continue in effect for a term of ten (10) years from the date of stockholder approval unless sooner terminated, provided that no incentive stock options may be granted under the Plan after April 5, 2028. Subject to Applicable Laws, Awards may be granted under the Plan upon Board approval, contingent on stockholder approval.

15.          Amendment, Suspension or Termination of the Plan.

(a)          The Board may at any time amend, suspend or terminate the Plan in any respect, except that it may not, without the approval of the stockholders obtained within twelve (12) months before or after the Board adopts a resolution authorizing any of the following actions, do any of the following:

(i)           increase the total number of shares that may be issued under the Plan (except by adjustment pursuant to Section 12);

(ii)          modify the provisions of Section 6 regarding eligibility for grants of ISOs may not be modified;

(iii)         the provisions of Section 7(a) regarding the exercise price at which shares may be offered pursuant to Options may not be modified (except by adjustment pursuant to Section 12);

(iv)         extend the expiration date of the Plan; and

(v)          except as provided in Section 12 (including, without limitation, any stock dividend, stock split, extraordinary cash dividend, recapitalization, reorganization, merger, consolidation, split-up, spin-off, combination, or exchange of shares), the Company may not amend an Award granted under the Plan to reduce its exercise price per share, cancel and regrant new Awards with lower prices per share than the original prices per share of the cancelled Awards, or cancel any Awards in exchange for cash or the grant of replacement Awards with an exercise price that is less than the exercise price of the original Awards, essentially having the effect of a repricing, without approval by the Company’s stockholders.

(b)          No Award may be granted during any suspension of the Plan or after termination of the Plan.

(c)          No suspension or termination of the Plan (including termination of the Plan under Section 15, above) shall adversely affect any rights under Awards already granted to a Grantee without his or her consent.

B-13

---

 

16.          Reservation of Shares.

(a)          The Company, during the term of the Plan, will at all times reserve and keep available such number of Shares as shall be sufficient to satisfy the requirements of the Plan.

(b)          The inability of the Company to obtain authority from any regulatory body having jurisdiction, which authority is deemed by the Company’s counsel to be necessary to the lawful issuance and sale of any Shares hereunder, shall relieve the Company of any liability in respect of the failure to issue or sell such Shares as to which such requisite authority shall not have been obtained.

17.          No Effect on Terms of Employment/Consulting Relationship. The Plan shall not confer upon any Grantee any right with respect to the Grantee’s Continuous Service, nor shall it interfere in any way with his or her right or the right of the Company or a Related Entity to terminate the Grantee’s Continuous Service at any time, with or without Cause, and with or without notice. The ability of the Company or any Related Entity to terminate the employment of a Grantee who is employed at will is in no way affected by its determination that the Grantee’s Continuous Service has been terminated for Cause for the purposes of this Plan.

18.          No Effect on Retirement and Other Benefit Plans. Except as specifically provided in a retirement or other benefit plan of the Company or a Related Entity, Awards shall not be deemed compensation for purposes of computing benefits or contributions under any retirement plan of the Company or a Related Entity, and shall not affect any benefits under any other benefit plan of any kind or any benefit plan subsequently instituted under which the availability or amount of benefits is related to level of compensation. The Plan is not a “Retirement Plan” or “Welfare Plan” under the Employee Retirement Income Security Act of 1974, as amended.

19.          Stockholder Approval. Continuance of the Plan shall be subject to approval by the stockholders of the Company within twelve (12) months before or after the date the Plan is adopted by the Board. Such stockholder approval shall be obtained in the degree and manner required under Applicable Laws. Any Award exercised before stockholder approval is obtained shall be rescinded if stockholder approval is not obtained within the time prescribed, and Shares issued on the exercise of any such Award shall not be counted in determining whether stockholder approval is obtained.

20.          Electronic Delivery. The Administrator may, in its sole discretion, decide to deliver any documents related to any Award granted under the Plan through an online or electronic system established and maintained by the Company or another third party designated by the Company or to request a Grantee’s consent to participate in the Plan by electronic means. Each Grantee hereunder consents to receive such documents by electronic delivery and agrees to participate in the Plan through an online or electronic system established and maintained by the Company or another third party designated by the Company, and such consent shall remain in effect throughout Grantee’s term of employment or service with the Company and any Related Entity and thereafter until withdrawn in writing by Grantee.

21.          Data Privacy. The Administrator may, in its sole discretion, decide to collect, use and transfer, in electronic or other form, personal data as described in this Plan or any Award for the exclusive purpose of implementing, administering and managing participation in the Plan. Each Grantee hereunder acknowledges that the Company holds certain personal information about Grantee, including, but not limited to, name, home address and telephone number, date of birth, social security number or other identification number, salary, nationality, job title, details of all Awards awarded, cancelled, exercised, vested or unvested, for the purpose of implementing, administering and managing the Plan (the “Data”). Each Grantee hereunder further acknowledges that Data may be transferred to any third parties assisting in the implementation, administration and management of the Plan and that these third parties may be located in jurisdictions that may have different data privacy laws and protections, and Grantee authorizes such third parties to receive, possess, use, retain and transfer the Data, in electronic or other form, for the purposes of implementing, administering and managing the Plan, including any requisite transfer of such Data as may be required to a broker or other third party with whom the recipient or the Company may elect to deposit any shares of Common Stock acquired upon any Award.

B-14

---

 

22.          Compliance with Section 409A. To the extent that the Administrator determines that any Award granted hereunder is subject to Section 409A of the Code, the Award Agreement evidencing such Award shall incorporate the terms and conditions necessary to avoid the consequences specified in Section 409A(a)(1) of the Code. To the extent applicable, the Plan and Award Agreements shall be interpreted in accordance with Section 409A of the Code and Department of Treasury regulations and other interpretive guidance issued thereunder, including without limitation any such regulations or other guidance that may be issued or amended after the effective date of the Plan. Notwithstanding any provision of the Plan to the contrary, in the event that following the effective date of the Plan the Administrator determines that any Award may be subject to Section 409A of the Code and related Department of Treasury guidance (including such Department of Treasury guidance as may be issued after the effective date of the Plan), the Administrator may adopt such amendments to the Plan and the applicable Award Agreement or adopt other policies and procedures (including amendments, policies and procedures with retroactive effect), or take any other actions, that the Administrator determines are necessary or appropriate to (1) exempt the Award from Section 409A of the Code and/or preserve the intended tax treatment of the benefits provided with respect to the Award, or (2) comply with the requirements of Section 409A of the Code and related Department of Treasury guidance.

23.          Unfunded Obligation. Grantees shall have the status of general unsecured creditors of the Company. Any amounts payable to Grantees pursuant to the Plan shall be unfunded and unsecured obligations for all purposes, including, without limitation, Title I of the Employee Retirement Income Security Act of 1974, as amended. Neither the Company nor any Related Entity shall be required to segregate any monies from its general funds, or to create any trusts, or establish any special accounts with respect to such obligations. The Company shall retain at all times beneficial ownership of any investments, including trust investments, which the Company may make to fulfill its payment obligations hereunder. Any investments or the creation or maintenance of any trust or any Grantee account shall not create or constitute a trust or fiduciary relationship between the Administrator, the Company or any Related Entity and a Grantee, or otherwise create any vested or beneficial interest in any Grantee or the Grantee’s creditors in any assets of the Company or a Related Entity. The Grantees shall have no claim against the Company or any Related Entity for any changes in the value of any assets that may be invested or reinvested by the Company with respect to the Plan.

24.          Construction. Captions and titles contained herein are for convenience only and shall not affect the meaning or interpretation of any provision of the Plan. Except when otherwise indicated by the context, the singular shall include the plural and the plural shall include the singular. Use of the term “or” is not intended to be exclusive, unless the context clearly requires otherwise.

Only those matters set forth in the notice of the special meeting or brought by or at the direction of the board of directors may be considered or acted upon at a special meeting of stockholders. In the case of a special meeting of stockholders called pursuant to the foregoing clause (4), the requesting holder(s) must (i) continue to own (for the holding period set forth in the bylaws of the Corporation as in effect from time to time) shares representing at least 25% (in the aggregate) of the then voting power of all shares of the Corporation entitled to vote on the matters to be brought before the proposed special meeting, (ii) provide information in writing regarding such stockholder(s), their stock ownership and the matters that they request to bring before the proposed special meeting and (iii) comply with procedures and other terms and conditions relating to special meetings as set forth in the bylaws of the Corporation from time to time.
