QUESTIONS AND ANSWERS ABOUT THESE PROXY MATERIALS AND VOTING

Why am I receiving these materials?

We have sent you these proxy materials because the Board of Directors (the “ Board ”) of MaxCyte, Inc. (sometimes referred to as the “ Company ” or “ MaxCyte ”) is soliciting your proxy to vote at the 2023 Annual Meeting of Stockholders (the “ Annual Meeting ”), including at any adjournments or postponements of the meeting. You are invited to attend the Annual Meeting to vote on the proposals described in this proxy statement. However, you do not need to attend the meeting to vote your shares. Instead, you may simply complete, sign and return the enclosed proxy card, or follow the instructions below to submit your proxy over the telephone or through the internet.

We intend to mail these proxy materials on or about May 3, 2023 to all stockholders of record entitled to vote at the Annual Meeting.

How do I attend the Annual Meeting?

The meeting will be held on Thursday, June 22, 2023 at 11:00 a.m. Eastern Time at 9713 Key West Avenue, Suite 400, Rockville, MD 20850 . Information on how to vote in person at the Annual Meeting is discussed below.

Who can vote at the Annual Meeting?

Only stockholders of record at the close of business on April 24, 2023 will be entitled to vote at the Annual Meeting. On the record date, there were 103,050,899 shares of common stock outstanding and entitled to vote.

Stockholder of Record: Shares Registered in Your Name

If on April 24, 2023 your shares were registered directly in your name with MaxCyte’s transfer agent, Computershare Trust Company N.A. (“ Computershare ”), then you are a stockholder of record. As a stockholder of record, you may vote in person at the meeting or vote by proxy. Whether or not you plan to attend the meeting, we urge you to fill out and return the enclosed proxy card or vote by proxy over the telephone or on the internet as instructed below to ensure your vote is counted.

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

If on April 24, 2023 your shares were held, not in your name, but rather in an account at a brokerage firm, bank or other similar organization, then you are the beneficial owner of shares held in “street name” and these proxy materials are 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, bank or other agent regarding how to vote the shares in your account. You are also invited to attend the Annual Meeting. However, since you are not the stockholder of record, you may not vote your shares in person at the meeting unless you request and obtain a valid proxy from your broker, bank or other agent.

What am I voting on?

There are three matters scheduled for a vote:

•

Election of three directors (Proposal 1);

•

Approval of an amendment and restatement of the 2022 Plan (Proposal 2); and

•

Ratification of selection by the Audit Committee of the Board of CohnReznick LLP as independent registered public accounting firm of the Company for its fiscal year ending December 31, 2023 (Proposal 3).

TABLE OF CONTENTS

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.

How do I vote?

You may either vote “For” all the nominees to the Board or you may “Withhold” your vote for any nominee you specify. For each of the other matters to be voted on, you may vote “For” or “Against” or abstain from voting.

The procedures for voting are fairly simple:

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 using the enclosed proxy card, vote by proxy over the telephone or vote by proxy through the internet. 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 the meeting and vote at the meeting even if you have already voted by proxy.

•

To vote in person, come to the Annual Meeting and we will give you a ballot when you arrive.

•

To vote prior to the Annual Meeting (until 11:59 p.m. Eastern Time on Wednesday, June 21, 2023), you may vote via the internet, by telephone or by completing and returning the proxy card or voting instruction form, each as described below.

•

To vote through the internet prior to the meeting, go to www.proxyvote.com and follow the instructions to submit your vote on an electronic proxy card. You will be asked to provide the company number and Control Number from the Notice. Your internet vote must be received by 11:59 p.m. Eastern Time on Wednesday, June 21, 2023 to be counted.

•

To vote over the telephone , dial toll-free 1-800-690-6903 using a touch-tone phone and follow the recorded instructions. You will be asked to provide the company number and Control Number from the Notice . Your telephone vote must be received by 11:59 p.m. Eastern Time on Wednesday, June 21, 2023 to be counted.

•

To vote using the proxy card , simply complete, sign and date the enclosed proxy card and return it promptly in the envelope provided. If you return your signed proxy card to us before the Annual Meeting, we will vote your shares as you direct. You should mail your signed proxy card sufficiently in advance for it to be received by Wednesday, June 21, 2023.

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 agent, you should have received a voting instruction form with these proxy materials from that organization rather than from MaxCyte. Simply complete and mail the voting instruction form to ensure that your vote is counted. Alternatively, you may vote by telephone or over the internet as instructed by your broker or bank. To vote at the Annual Meeting, you may be required to obtain a valid proxy from your broker, bank or other agent. Follow the instructions from your broker, bank or other agent included with these proxy materials, or contact that organization to request a proxy form.

Internet proxy voting is provided to allow you to vote your shares online, with procedures designed to ensure the authenticity and correctness of your proxy vote instructions. However, please be aware that you must bear any costs associated with your internet access, such as usage charges from internet access providers and telephone companies.

How many votes do I have?

On each matter to be voted upon, you have one vote for each share of common stock you owned as of April 24, 2023.

TABLE OF CONTENTS

If I am a stockholder of record and I do not vote, or if I return a proxy card or otherwise vote without giving specific voting instructions, what happens?

If you are a stockholder of record and do not vote by completing your proxy card, by telephone, through the internet or in person at the Annual Meeting, your shares will not be voted.

If you return a signed and dated proxy card or otherwise vote without marking voting selections, your shares will be voted, as applicable, “For” the election of all three nominees for director (Proposal 1), “For” the approval of an amendment and restatement of the 2022 Plan (Proposal 2) and “For” the ratification of CohnReznick as the independent registered public accounting firm for the fiscal year ending December 31, 2023 (Proposal 3). If any other matter is properly presented at the meeting, your proxyholder (one of the individuals named on your proxy card) will vote your shares using his or her best judgment.

If I am a beneficial owner of shares held in street name and I do not provide my broker or bank with voting instructions, what happens?

If you are a beneficial owner of shares held in street name and you do not instruct your broker, bank or other agent how to vote your shares, your broker, bank or other agent may still be able to vote your shares in its discretion. In this regard, under applicable rules, brokers, banks and other securities intermediaries may use their discretion to vote your “uninstructed” shares with respect to matters considered to be “routine” under such rules, but not with respect to “non-routine” matters. Proposals 1 and 2 are considered to be “non-routine” under such rules, meaning that your broker may not vote your shares on these proposals in the absence of your voting instructions. However, Proposal 3 is considered to be “routine” under such rules, meaning that if you do not return voting instructions to your broker by its deadline, your shares may be voted by your broker in its discretion on Proposal 3.

If you a beneficial owner of shares held in street name, and you do not plan to attend the meeting, in order to ensure your shares are voted in the way you would prefer, you must provide voting instructions to your broker, bank or other agent by the deadline provided in the materials you receive from your broker, bank or other agent .

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 agents for the cost of forwarding proxy materials to beneficial owners.

We have engaged D.F. King & Co., Inc. to assist us in the solicitation of proxies for the Annual Meeting. We expect to pay D.F. King a fee of approximately $20,000 plus out-of-pocket expenses. You may contact D.F. King at:

	United Kingdom :			United States :
	D.F. King Ltd 65 Gresham St, London EC2V 7NQ, United Kingdom Email: proxy@dfkingltd.com Telephone: +44 20 7920 9700			D.F. King & Co., Inc. 48 Wall Street, 22nd Floor New York, NY 10005 Email: mxct@dfking.com Telephone: +1 212 269 5550

What does it mean if I receive more than one set of proxy materials?

If you receive more than one set of proxy materials, your shares may be registered in more than one name or in different accounts. Please follow the voting instructions on the proxy cards in the proxy materials to ensure that all of your shares are voted.

Can I change my vote after submitting my proxy?

Stockholder of Record: Shares Registered in Your Name

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

TABLE OF CONTENTS

•

You may submit another properly completed proxy card with a later date.

•

You may grant a subsequent proxy by telephone or through the internet.

•

You may send a timely written notice that you are revoking your proxy to MaxCyte’s Secretary at 9713 Key West Avenue, Suite 400, Rockville, Maryland 20850.

•

You may attend the Annual Meeting and vote in person. Simply attending the meeting will not, by itself, revoke your proxy.

Your most current proxy card or telephone or internet proxy is the one that is counted.

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

If your shares are held by your broker, bank or other agent, you should follow the instructions provided by that organization.

When are stockholder proposals and director nominations due for next year’s Annual Meeting?

To be considered for inclusion in next year’s proxy materials, your proposal must be submitted in writing by January 2, 2024, to our Corporate Secretary at 9713 Key West Avenue, Suite 400, Rockville, Maryland 20850. If you wish to nominate an individual for election at, or bring business other than through a stockholder proposal before, the 2024 Annual Meeting of Stockholders, you must deliver your notice to our Corporate Secretary at the address above between February 23, 2024 and March 24, 2024. In addition, stockholders who intend to solicit proxies in support of director nominees other than our Board’s nominees must also comply with the additional requirements of the SEC’s Rule 14a-19(b). In the event that next year’s annual meeting is scheduled to be held before May 23, 2024, or after July 22, 2024, then you must deliver your notice to our Corporate Secretary at the foregoing address at least 90 days, but not more than 120 days, prior to the date of next year’s annual meeting, or not more than 10 days after we publicly announce the date of next year’s annual meeting. Your notice to the Corporate Secretary must set forth information specified in our Amended and Restated Bylaws, including your name and address and the number of shares of our stock that you beneficially own.

If you propose to bring business before an annual meeting other than a director nomination, your notice must also include, as to each matter proposed: 1) a brief description of the business desired to be brought before the annual meeting and the reasons for conducting that business at the annual meeting; and 2) any material interest you have in that business. If you propose to nominate an individual for election as a director, your notice must also include, as to each person you propose to nominate for election as a director: 1) the name, age, business address and residence address of the person; 2) the principal occupation or employment of the person; 3) the number of shares of our stock that are owned of record and beneficially owned by the person; 4) the date or dates on which the shares were acquired and the investment intent of the acquisition; and 5) any other information concerning the person as would be required to be disclosed in a proxy statement soliciting proxies for the election of that person as a director in an election contest (even if an election contest is not involved), or that is otherwise required to be disclosed pursuant to Section 14 of the Securities Exchange Act of 1934 (the “ Exchange Act ”), and the rules and regulations promulgated under the Exchange Act, including the person’s written consent to being named as a nominee and to serving as a director if elected. We may require any proposed nominee to furnish other information as we may reasonably require to determine the eligibility of the proposed nominee to serve as an independent director or that could be material to a reasonable stockholder’s understanding of the independence, or lack of independence, of the proposed nominee.

For more information, and for more detailed requirements, please refer to our Amended and Restated Bylaws, filed as an exhibit to our most recent Annual Report on Form 10-K filed with the Securities and Exchange Commission (the “ SEC ”).

How are votes counted?

Votes will be counted by the inspector of election appointed for the meeting, who will separately count: with respect to Proposal 1, votes “For,” “Withhold” and broker non-votes; and, with respect to Proposals 2

TABLE OF CONTENTS

and 3, votes “For,” “Against” and abstentions, as well as broker non-votes if applicable. Broker non-votes on Proposals 1 and 2 will have no effect and will not be counted towards the vote totals for these proposals. We do not expect broker non-votes on Proposal 3. Abstentions on Proposals 2 and 3 will be counted towards the vote totals for these proposals and will have the same effect as “Against” votes.

What are “broker non-votes”?

A “broker non-vote” occurs when your broker submits a proxy for the meeting with respect to “routine” matters but does not vote on “non-routine” matters because you did not provide voting instructions on these matters. These un-voted shares are counted as “broker non-votes.” Proposals 1 and 2 are considered to be “non-routine” and we therefore expect broker non-votes on these proposals. However, because Proposal 3 is considered “routine,” we do not expect broker non-votes on this proposal.

As a reminder, if you are a beneficial owner of shares held in street name, in order to ensure your shares are voted in the way you would prefer, you must provide voting instructions to your broker, bank or other agent by the deadline provided in the materials you receive from your broker, bank or other agent .

How many votes are needed to approve each proposal?

For the election of directors (Proposal 1), the three nominees receiving the most “For” votes from the holders of shares present in person or represented by proxy and entitled to vote on the election of directors will be elected. Only votes “For” will affect the outcome.

To be approved, Proposal 2, approval of an amendment and restatement of the 2022 Plan, must receive “For” votes from the holders of a majority of shares present in person or represented by proxy and entitled to vote on the matter. If you mark your proxy to “Abstain” from voting, it will have the same effect as an “Against” vote. Broker non-votes will have no effect.

To be approved, Proposal 3, ratification of the selection of CohnReznick LLP as the Company’s independent registered public accounting firm for the year ending December 31, 2023, must receive “For” votes from the holders of a majority of shares present in person or represented by proxy and entitled to vote on the matter. If you mark your proxy to “Abstain” from voting, it will have the same effect as an “Against” vote. Since brokers have authority to vote on your behalf with respect to Proposal 3, we do not expect broker non-votes on this proposal.

What is the quorum requirement?

A quorum of stockholders is necessary to hold a valid meeting. A quorum will be present if stockholders holding at least a majority of the outstanding shares entitled to vote are present at the meeting or represented by proxy. On the record date, there were 103,050,899 shares outstanding and entitled to vote. Thus, the holders of 51,525,450 shares must be present in person or represented by proxy at the meeting to have a quorum.

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

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 published in a current report on Form 8-K that we expect to file within four business days after the Annual Meeting.

What proxy materials are available on the internet?

The proxy statement and annual report to stockholders are available at www.proxyvote.com.

TABLE OF CONTENTS

PROPOSAL 1

ELECTION OF DIRECTORS

MaxCyte’s Board is divided into three classes. Each class has a three-year term. Vacancies on the Board may be filled only by persons elected by a majority of the remaining directors. A director elected by the Board to fill a vacancy in a class, including vacancies created by an increase in the number of directors, shall serve for the remainder of the full term of that class and until the director’s successor is duly elected and qualified.

The Board presently has nine members. There are three directors in Class II whose term of office expires in 2023. Each of the three nominees listed below is currently a director of the Company. Mr. Erck and Mr. Mandell were previously elected by the stockholders. Mr. Balthrop was appointed by the Board in November 2022 and was identified by a third-party search firm for evaluation by the Nominating and Corporate Governance Committee of the Board. If elected at the Annual Meeting, each of these three nominees would serve until the 2026 annual meeting and until his successor has been duly elected and qualified, or, if sooner, until the director’s death, resignation or removal. It is the Company’s policy to encourage directors and nominees for director to attend the Annual Meeting, in person or telephonically. All of our directors attended the 2022 Annual Meeting of Stockholders.

Directors are elected by a plurality of the votes of the holders of shares present in person or represented by proxy and entitled to vote on the election of directors. Accordingly, the three nominees receiving the highest number of affirmative votes will be elected. Shares represented by executed proxies will be voted, if authority to do so is not withheld, for the election of the three nominees named below. If any nominee becomes unavailable for election as a result of an unexpected occurrence, shares that would have been voted for that nominee will instead be voted for the election of a substitute nominee proposed by MaxCyte. Each person nominated for election has agreed to serve if elected. The Company’s management has no reason to believe that any nominee will be unable to serve.

The following is a brief biography of each nominee for director and each director whose term will continue after the Annual Meeting, including a discussion of the specific experience, qualifications, attributes or skills of each nominee and continuing director that led the Nominating and Corporate Governance Committee (the “ N&CG Committee ”) of the Board to recommend that person as a nominee for director or that describes the reasons as to why the Company believes that the director should continue to serve on the Board.

The N&CG Committee seeks to assemble a board that, as a whole, possesses the appropriate balance of professional and industry knowledge, financial expertise and high-level management experience necessary to oversee and direct the Company’s business. To that end, the N&CG Committee has identified and evaluated nominees in the broader context of the Board’s overall composition, with the goal of recruiting members who complement and strengthen the skills of other members and who also exhibit integrity, collegiality, sound business judgment and other qualities that the N&CG Committee views as critical to effective functioning of the Board. To provide a mix of experience and perspective on the Board, the N&CG Committee also takes into account gender, age and ethnic diversity.

Nominees for Election for a Three-year Term Expiring at the 2026 Annual Meeting

Art Mandell , age 70

Art Mandell has served on our Board since 2006. Mr. Mandell served as president and chief operating officer of Prestwick Pharmaceuticals, Inc. from 2005 to 2007.

Before Cellective, Mr. Mandell served as president and chief executive officer and director of Stemron Corporation from 2001 to 2003, and as senior vice president and chief business officer of Human Genome Sciences, Inc. from 1997 to 2001. Mr. Mandell began his healthcare career at Syntex Pharmaceutical Corporation where he spent 14 years in various senior management positions both domestically and abroad.

TABLE OF CONTENTS

Santa Clara University. Our Board believes Mr. Mandell’s extensive knowledge and experience in the pharmaceuticals and biotechnology industries qualify him to serve as a director.

Stanley C. Erck , age 75

Stanley Erck has served on our Board since 2005. Mr. Erck served as president and chief executive officer of Novavax, Inc. from 2011, and as a director of Novavax from 2009, until his retirement in January 2023. Mr. Erck previously served as executive chairman of Novavax from 2010 to 2011 and interim chief financial officer from 2017 to 2018. From 2000 to 2008, Mr. Erck served as president and chief executive officer of Iomai Corporation, a developer of vaccines and immune system therapies, which was acquired in 2008 by Intercell AG. He also previously held leadership positions at Procept, a publicly traded immunology company, Integrated Genetics, now Sanofi Genzyme and Baxter International. Within the past five years, Mr. Erck served on the board of directors of BioCryst Pharmaceuticals. Mr. Erck currently serves on the board of directors of MDBio Foundation. Mr. Erck received a B.S. in economics from the University of Illinois and an M.B.A. from the University of Chicago. During his tenure as chief executive officer of Novavax, Mr. Erck led the company from preclinical development through global commercialization with first year revenues of over $2 billion.

INFORMATION REGARDING THE BOARD OF DIRECTORS AND CORPORATE GOVERNANCE

Independence of The Board of Directors

As required under the Nasdaq Stock Market (“ Nasdaq ”) listing standards, a majority of the members of a listed company’s board of directors must qualify as “independent,” as affirmatively determined by the board of directors. The Board consults with the Company’s counsel to ensure that the Board’s determinations are consistent with relevant securities and other laws and regulations regarding the definition of “independent,” including those set forth in pertinent listing standards of Nasdaq, as in effect from time to time.

Consistent with these considerations, after review of all relevant identified transactions or relationships between each director, or any of his or her family members, and the Company, its senior management and its independent auditors, the Board has affirmatively determined that the following eight directors are independent directors within the meaning of the applicable Nasdaq listing standards: Dr. Al-Wakeel, Mr. Brooke, Dr. Douglas, Ms. Hemrajani, Mr. Erck, Mr. Johnston, Mr. Mandell and Mr. Balthrop. In making this determination, the Board found that none of these directors or nominees for director had a material or other disqualifying relationship with the Company.

Board Leadership Structure

The Board has an independent chairman, Dr. Douglas, who has authority, among other things, to call and preside over Board meetings, including meetings of the independent directors, to set meeting agendas and to determine materials to be distributed to the Board. Accordingly, the Chairman has substantial ability to shape the work of the Board. The Company believes that separation of the positions of Chairman and Chief Executive Officer reinforces the independence of the Board in its oversight of the business and affairs of the Company. In addition, the Company believes that having an independent Chairman creates an environment that is more conducive to objective evaluation and oversight of management’s performance, increasing management accountability and improving the ability of the Board to monitor whether management’s actions are in the best interests of the Company and its stockholders. As a result, the Company believes that having an independent Chairman can enhance the effectiveness of the Board as a whole.

Role of the Board in Risk Oversight

One of the Board’s key functions is informed oversight of the Company’s risk management process. The Board does not have a standing risk management committee, but rather administers this oversight function directly through the Board as a whole, as well as through various Board standing committees that address risks inherent in their respective areas of oversight. In particular, our Board is responsible for monitoring and assessing strategic risk exposure, including a determination of the nature and level of risk appropriate for the Company. The Audit Committee of our Board (the “ Audit Committee ”) has the responsibility to consider and discuss our major financial risk exposures and the steps our management has taken to monitor and control these exposures, including guidelines and policies to govern the process by which risk assessment and management is undertaken. The Audit Committee also monitors compliance with legal and regulatory requirements, in addition to oversight of the performance of our internal audit function. Audit Committee responsibilities also include oversight of cybersecurity risk management, and, to that end, the Audit Committee typically meets twice annually with both IT and business personnel responsible for cybersecurity risk management and receives periodic reports from the head of cybersecurity risk management, as well as incidental reports as matters arise. Our N&CG Committee monitors the effectiveness of our corporate governance guidelines, including whether they are successful in preventing illegal or improper liability-creating conduct. The Compensation Committee of our Board (the “ Compensation Committee ”) assesses and monitors whether any of our compensation policies and programs has the potential to encourage excessive risk-taking. Typically, the entire Board meets with the head of the Company’s risk management group at least annually, and the applicable Board committees meet at least annually with the employees responsible for risk management in the committees’ respective areas of oversight. Both the Board as a whole and the various standing committees receive periodic reports from the head of risk management, as well as incidental reports as matters may arise. It is the responsibility of the committee chairs to report findings regarding material risk exposures to the Board as quickly as possible. The Board has delegated to the Board’s lead independent

TABLE OF CONTENTS

director the responsibility of coordinating between the Board and management with regard to the determination and implementation of responses to any problematic risk management issues.

Meetings of The Board of Directors

The Board met five times during the last fiscal year. Each Board member attended 75% or more of the aggregate number of meetings of the Board and of the committees on which he or she served, held during the portion of the last fiscal year for which he or she was a director or committee member.

Information Regarding Committees of the Board of Directors

The Board has three committees: the Audit Committee, the Compensation Committee and the N&CG Committee. The following table provides membership and meeting information for each of the Board committees:

Committee Chairperson

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 Board has determined that each member of each committee meets the applicable Nasdaq rules and regulations regarding “independence” and each member is free of any relationship that would impair his or her individual exercise of independent judgment with regard to the Company.

Below is a description of each committee of the Board.

Audit Committee

The Audit Committee was established by the Board in accordance with Section 3(a)(58)(A) of the Exchange Act to oversee the Company’s corporate accounting and financial reporting processes and audits of its financial statements. Specific responsibilities of our Audit Committee include:

•

helping our Board oversee our corporate accounting and financial reporting processes;

•

managing the selection, engagement, qualifications, independence and performance of a qualified firm to serve as the independent registered public accounting firm to audit our financial statements;

•

discussing the scope and results of the audit with the independent registered public accounting firm, and reviewing, with management and the independent accountants, our interim and year-end operating results;

•

developing procedures for employees to submit concerns anonymously about questionable accounting or audit matters;

•

reviewing related person transactions;

TABLE OF CONTENTS

•

obtaining and reviewing a report by the independent registered public accounting firm at least annually that describes our internal quality control procedures, any material issues with such procedures and any steps taken to deal with such issues when required by applicable law; and

•

approving or, as permitted, pre-approving, audit and permissible non-audit services to be performed by the independent registered public accounting firm.

The Audit Committee is currently composed of four directors: Dr. Al-Wakeel and Messrs. Brooke , Johnston and Mandell, with Mr. Brooke serving as chairman. The Audit Committee met six times during the fiscal year ended December 31, 2022. The Board has adopted a written Audit Committee charter that is available to stockholders on the Company’s website at https://investors.maxcyte.com/corporate-governance/documents-charters.

The Board reviews the Nasdaq listing standards definition of independence for Audit Committee members on an annual basis and has determined that all members of the Company’s Audit Committee are independent (as independence is currently defined in Rule 5605(c)(2)(A)(i) and (ii) of the Nasdaq listing standards).

The Board has also determined that Mr. Brooke and Dr. Al-Wakeel each qualify as an “audit committee financial expert,” as defined in applicable SEC rules. The Board made a qualitative assessment of each of Mr. Brooke’s and Dr. Al-Wakeel’s level of knowledge and experience based on a number of factors, including their formal education and experience.

Report of the Audit Committee of the Board of Directors*

The Audit Committee has reviewed and discussed the audited financial statements for the fiscal year ended December 31, 2022 with management of the Company. The Audit Committee has discussed with the independent registered public accounting firm the matters required to be discussed by the applicable requirements of the Public Company Accounting Oversight Board (“ PCAOB ”) and the SEC. The Audit Committee has also received the written disclosures and the letter from the independent registered public accounting firm required by applicable requirements of the PCAOB regarding the independent accountants’ communications with the Audit Committee concerning independence, and has discussed with the independent registered public accounting firm the accounting firm’s independence. Based on the foregoing, the Audit Committee has recommended to the Board that the audited consolidated financial statements be included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2022.

Compensation Committee

The Compensation Committee is currently composed of three directors: Messrs. Brooke and Erck and Ms. Hemrajani, with Ms. Hemrajani serving as the chairperson. All members of the Compensation Committee are independent (as independence is currently defined in Rule 5605(d)(2) of the Nasdaq listing standards). The Compensation Committee met five times during the fiscal year ended December 31, 2022. The Board has adopted a written Compensation Committee charter that is available to stockholders on the Company’s website at https://investors.maxcyte.com/corporate-governance/documents-charters.

The Compensation Committee of the Board acts on behalf of the Board to review, adopt and oversee the Company’s compensation strategy, policies, plans and programs. Specific responsibilities of our Compensation Committee include:

•

reviewing and approving the compensation of our chief executive officer, other executive officers and senior management;

The material in this report is not “soliciting material,” is not deemed “filed” with the SEC and is not to be incorporated by reference in any filing of the Company under the Securities Act of 1933, as amended, or the Exchange Act, whether made before or after the date hereof and irrespective of any general incorporation language in any such filing.

TABLE OF CONTENTS

•

reviewing and recommending to our Board the compensation paid to our non-executive directors;

•

administering our equity incentive plans and other benefit programs;

•

reviewing, adopting, amending and terminating incentive compensation and equity plans, severance agreements, profit sharing plans, bonus plans, change-of-control protections and any other compensatory arrangements for our executive officers and other senior management; and

•

reviewing and establishing general policies relating to compensation and benefits of our employees, including our overall compensation philosophy.

Once required by SEC rules, the Compensation Committee will review with management the Company’s Compensation Discussion and Analysis and consider whether to recommend that it be included in proxy statements and other filings.

Compensation Committee Processes and Procedures

Typically, the Compensation Committee meets at least four times annually and with greater frequency if necessary. The agenda for each meeting is usually developed by the Chairman of the Compensation Committee, in consultation with the Company’s Chief Executive Officer and other executives, and its compensation consultant. The Compensation Committee meets regularly in executive session. Various members of management and other employees as well as outside advisors or consultants may be invited by the Compensation Committee to make presentations, to provide data and other background information or advice or to otherwise participate in Compensation Committee meetings. The Chief Executive Officer may not participate in, or be present during, any deliberations or determinations of the Compensation Committee regarding his compensation. The charter of the Compensation Committee grants the Compensation Committee full access to all books, records, facilities and personnel of the Company. In addition, under the charter, the Compensation Committee has the authority to obtain, at the expense of the Company, advice and assistance from compensation consultants and internal and external legal, accounting or other advisors and other external resources that the Compensation Committee considers necessary or appropriate in the performance of its duties. The Compensation Committee has direct responsibility for the oversight of the work of any consultants or advisers engaged for the purpose of advising the Committee. In particular, the Compensation Committee has the sole authority to retain, in its sole discretion, compensation consultants to assist in its evaluation of executive and director compensation, including the authority to approve the consultant’s reasonable fees and other retention terms. Under the charter, the Compensation Committee may select, or receive advice from, a compensation consultant, legal counsel or other adviser to the Compensation Committee, other than in-house legal counsel and certain other types of advisers, only after taking into consideration six factors, prescribed by the SEC and Nasdaq, that bear upon the adviser’s independence; however, there is no requirement that any adviser be independent.

During the past fiscal year, after taking into consideration the six factors prescribed by the SEC and Nasdaq described above, the Compensation Committee engaged Arnosti Consulting, Inc. (“ Arnosti ”) as compensation consultants. The Compensation Committee requested that Arnosti:

•

evaluate the efficacy of the Company’s existing compensation strategy and practices in supporting and reinforcing the Company’s long-term strategic goals; and

•

assist in refining the Company’s compensation strategy and in developing and implementing an executive compensation program to execute that strategy.

As part of its engagement, Arnosti was requested by the Compensation Committee to develop a comparative group of companies and to perform analyses of competitive performance and compensation levels for that group. Arnosti provided data and guidance in developing recommendations for compensation of executives, and made direct recommendations to the Compensation Committee with regards to compensation of non-executive directors.

Historically, the Compensation Committee has made most of the significant adjustments to annual compensation, determined bonus and equity awards and established new corporate performance objectives at one or more meetings held during the first quarter of the year. The Compensation Committee also considers matters related to individual compensation, such as compensation for new executive hires, as well as high-level

TABLE OF CONTENTS

strategic issues, such as the effectiveness of our compensation strategy, potential modifications to that strategy and new trends, plans or approaches to compensation, at various meetings throughout the year. Generally, the Compensation Committee’s process comprises two related elements: the determination of compensation levels and the establishment of performance objectives for the current year. For executives other than the Chief Executive Officer, the Compensation Committee solicits and considers evaluations and recommendations submitted to the Compensation Committee by the Chief Executive Officer. In the case of the Chief Executive Officer, the evaluation of his performance is conducted by the Compensation Committee for recommendation to the full Board, which determines any adjustments to his compensation as well as equity awards to be granted. For all executives and directors as part of its deliberations, the Compensation Committee may review and consider, as appropriate, the results of the self-evaluation questionnaires provided by the N&CG Committee to our independent directors, as well as materials such as financial reports and projections, operational data, tax and accounting information, tally sheets that set forth the total compensation that may become payable to executives in various hypothetical scenarios, executive and director stock ownership information, stock performance data, analyses of historical executive compensation levels and current Company-wide compensation levels and recommendations of the Compensation Committee’s compensation consultant, including analyses of executive and director compensation paid at other companies in our peer group.

Nominating and Corporate Governance Committee

The N&CG Committee of the Board is responsible for identifying, reviewing and evaluating candidates to serve as directors of the Company (consistent with criteria approved by the Board), reviewing and evaluating incumbent directors, recommending to the Board for selection candidates for election to the Board, making recommendations to the Board regarding the membership of the committees of the Board, assessing the performance of management and the Board, and developing a set of corporate governance principles for the Company.

The N&CG Committee is currently composed of four directors: Messrs. Mandell, Erck and Balthrop and Dr. Douglas, with Mr. Mandell serving as chairman. All members of the N&CG Committee are independent (as independence is currently defined in Rule 5605(a)(2) of the Nasdaq listing standards). The N&CG Committee met three times during the fiscal year ended December 31, 2022. The Board has adopted a written N&CG Committee charter that is available to stockholders on the Company’s website and https://investors.maxcyte.com/corporate-governance/documents-charters.

The N&CG Committee believes that candidates for director should have certain minimum qualifications, including the ability to read and understand basic financial statements, being over 21 years of age and having the highest personal integrity and ethics. The N&CG Committee also considers such factors as possessing relevant expertise upon which to be able to offer advice and guidance to management, having sufficient time to devote to the affairs of the Company, demonstrated excellence in his or her field, having the ability to exercise sound business judgment and having the commitment to rigorously represent the long-term interests of the Company’s stockholders. However, the N&CG Committee retains the right to modify these qualifications from time to time. Candidates for director nominees are reviewed in the context of the current composition of the Board, the operating requirements of the Company and the long-term interests of stockholders. In conducting this assessment, the N&CG Committee typically considers diversity (including gender, racial and ethnic diversity), age, skills and such other factors as it deems appropriate, given the current needs of the Board and the Company, to maintain a balance of knowledge, experience and capability. We have no formal policy regarding board diversity.

The N&CG Committee appreciates the value of thoughtful Board refreshment, and regularly identifies and considers qualities, skills and other director attributes that would enhance the composition of the Board. In the case of incumbent directors whose terms of office are set to expire, the N&CG Committee reviews these directors’ overall service to the Company during their terms, including the number of meetings attended, level of participation, quality of performance and any other relationships and transactions that might impair the directors’ independence. The N&CG Committee will also take into account the results of the Board’s self-evaluation, conducted annually on a group and individual basis. In the case of new director candidates, the N&CG Committee also determines whether the nominee is independent for Nasdaq purposes, which determination is based upon applicable Nasdaq listing standards, applicable SEC rules and regulations and

TABLE OF CONTENTS

the advice of counsel, if necessary. The N&CG Committee then uses its network of contacts to compile a list of potential candidates, but may also engage, if it deems appropriate, a professional search firm. The N&CG Committee conducts any appropriate and necessary inquiries into the backgrounds and qualifications of possible candidates after considering the function and needs of the Board. The N&CG Committee meets to discuss and consider the candidates’ qualifications and then selects a nominee for recommendation to the Board by majority vote.

The N&CG Committee will consider director candidates recommended by the Company’s stockholders. The N&CG Committee does not intend to alter the manner in which it evaluates a candidate for nomination to the Board based on whether or not the candidate was recommended by a stockholder of the Company.

Stockholders who wish to recommend individuals for consideration by the N&CG Committee to become nominees for election to the Board at an annual meeting of stockholders must do so by delivering a written recommendation to the Nominating and Corporate Governance Committee c/o MaxCyte, Inc., 9713 Key West Avenue, Suite 400, Rockville, Maryland 20850, Attn: General Counsel. Each submission must set forth:

•

the name and address of the stockholder on whose behalf the submission is made;

•

the number of shares of the Company’s common stock that are owned beneficially by such stockholder as of the date of the submission;

•

the full name of the proposed candidate;

•

a description of the proposed candidate’s business experience for at least the previous five years;

•

complete biographical information for the proposed candidate; and

•

a description of the proposed candidate’s qualifications as a director.

Any such submission must be accompanied by the written consent of the proposed candidate to be named as a nominee and to serve as a director if elected. All written submissions received from stockholders that include the information described above will be reviewed by the N&CG Committee at its next appropriate meeting. If a stockholder wishes the N&CG Committee to consider a director candidate for nomination at an annual meeting of stockholders, then the recommendation must be provided at least 90 days, but not more than 120 days, prior to the anniversary date of the preceding year’s annual meeting of stockholders.

Communications With The Board Of Directors

The Board has adopted a process by which stockholders may communicate with the Board or any of its directors. Stockholders who wish to communicate with the Board may do so by sending written communications addressed to the Board or such director c/o MaxCyte, Inc., 9713 Key West Avenue, Suite 400, Rockville, Maryland 20850, Attn: General Counsel.

The General Counsel will forward such communication to the Board or to any individual director to whom the communication is addressed unless the communication contains advertisements or solicitations or is unduly hostile, threatening or similarly inappropriate, in which case the General Counsel will discard the communication.

Code of Ethics

The Company has adopted the MaxCyte, Inc. Code of Conduct and Ethics that applies to all officers, directors and employees. The Code of Business Conduct and Ethics is available on the Company’s website at https://investors.maxcyte.com/corporate-governance/documents-charters .

TABLE OF CONTENTS

Corporate Governance Guidelines

In 2021, the Board documented the governance practices to be followed by the Company by adopting Corporate Governance Guidelines to assure that the Board will have the necessary authority and practices in place to review and evaluate the Company’s business operations as needed and to make decisions that are independent of the Company’s management. The guidelines are also intended to align the interests of directors and management with those of the Company’s stockholders. The Corporate Governance Guidelines set forth the practices the Board intends to follow with respect to board composition and selection including diversity, board meetings and involvement of senior management, Chief Executive Officer performance evaluation, succession planning and board committees and compensation.

Hedging Policy

We do not currently have any practices or policies regarding hedging or offsetting any decrease in the market value of our equity securities.

PROPOSAL 2

APPROVAL OF AN AMENDMENT AND RESTATEMENT OF THE 2022 EQUITY
INCENTIVE PLAN

Background

Our Board approved an amendment and restatement of the MaxCyte, Inc. 2022 Equity Incentive Plan (the “2022 Plan”) in April 2023, subject to approval by our stockholders. For purposes of this Proposal 2, we refer to the 2022 Plan, as amended and restated by our Board in April 2023 and attached hereto as Appendix A, as the “Amended 2022 Plan.” The Amended 2022 Plan contains the following changes from the 2022 Plan:

•

The aggregate number of shares of our common stock that may be issued under the 2022 Plan has been increased by 6,069,000 shares under the Amended 2022 Plan, subject to adjustment for certain changes in our capitalization.

•

The liberal share recycling provision for Appreciation Awards (as defined below) in the 2022 Plan has been removed. As a result, the Amended 2022 Plan does not contain any liberal share recycling provisions. Accordingly, the following shares will not become available again for issuance under the Amended 2022 Plan:

(i)

shares that are reacquired or withheld (or not issued) by us to satisfy the exercise or strike price of an Appreciation Award or the purchase price of a Full Value Award (each as defined below);

(ii)

shares that are reacquired or withheld (or not issued) by us to satisfy a tax withholding obligation in connection with an Appreciation Award or Full Value Award;

(iii)

shares repurchased by us on the open market with the proceeds of the exercise or strike price of an Appreciation Award or the purchase price of a Full Value Award; and

(iv)

in the event that a stock appreciation right is settled in shares of common stock, the gross number of shares of common stock subject to the award.

An “Appreciation Award” is a stock option or stock appreciation right with an exercise or strike price that is at least 100% of the fair market value of our common stock on the date of grant, and a “Full Value Award” is an equity award that is not an Appreciation Award.

The definition of shares that can be returned to the Amended 2022 Plan from prior plans has been revised as set forth below under the section entitled “Requested Shares.”

Approval of the Amended 2022 Plan by our stockholders will allow us to continue to grant stock options, restricted stock unit awards and other awards at levels determined appropriate by our Board or Compensation Committee. The Amended 2022 Plan will allow us to continue to grant a broad array of equity incentives and performance cash incentives in order to secure and retain the services of our employees, consultants and directors, and to provide long-term incentives that align the interests of our employees, consultants and directors with the interests of our stockholders. Our Board believes that the Amended 2022 Plan is an integral part of our long-term compensation philosophy and that the Amended 2022 Plan is necessary to continue providing the appropriate levels and types of equity compensation.

Requested Shares

Subject to adjustment for certain changes in our capitalization, if this Proposal 2 is approved by our stockholders, the aggregate number of shares of common stock that may be issued under the Amended 2022 Plan will not exceed the sum of (i) 6,069,000 new shares, plus (ii) the 1,928,000 shares originally reserved under the 2022 Plan, plus (iii) the number of unallocated shares remaining available for grant under the MaxCyte, Inc. Long-Term Incentive Plan (the “LTIP”) as of the original effective date of the 2022 Plan, plus (iii) the Prior Plans’ Returning Shares (as defined below), as such shares become available from time to time.

The term “Prior Plans’ Returning Shares” refers to the following shares of our common stock subject to any outstanding award granted under the LTIP or the MaxCyte, Inc. 2021 Inducement Plan (the “Inducement

TABLE OF CONTENTS

Plan”) and that following the effective date of the 2022 Plan: (i) are not issued because the stock award or any portion thereof expires or otherwise terminates without all of the shares covered by such stock award having been issued; (ii) are not issued because such stock award or any portion thereof is settled in cash; or (iii) are forfeited back to or repurchased by us because of the failure to meet a contingency or condition required for the vesting of such shares. Previously, under the terms of the 2022 Plan, clause (ii) applied only to Appreciation Awards (whereas under the Amended 2022 Plan it applies to all awards), and the definition included, for Appreciation Awards only, shares withheld or reacquired to satisfy an exercise, strike or purchase price and shares withheld or reacquired to satisfy a tax withholding obligation (whereas under the Amended 2022 Plan the definition excludes such shares, such that they will not return to the Amended 2022 Plan for future grant).

Retirement of the Inducement Plan and LTIP

In December 2021, the Board adopted the Inducement Plan consisting of 2,500,000 shares of common stock, which is a non-stockholder approved stock plan adopted pursuant to the “inducement exception” provided under Nasdaq listing rules. Simultaneous with approval of the 2022 Plan, we retired the Inducement Plan and only issue shares of common stock under the 2022 Plan.

In addition, following approval of the 2022 Plan, we no longer grant awards under the LTIP.

Why We Believe It Is Important to Vote to Approve the Amended 2022 Plan

Equity Awards Are an Important Part of Our Compensation Philosophy

Our Board believes that our future success depends, in large part, on our ability to maintain a competitive position in retaining and motivating our employees, consultants and directors and that the issuance of equity awards is a key element in accomplishing these goals. The Amended 2022 Plan will allow us to continue to provide performance-based incentives to our eligible employees. Therefore, the Board believes that the Amended 2022 Plan is in the best interests of the Company and its stockholders and recommends a vote in favor of this Proposal 2.

The Size of Our Share Reserve Request Is Reasonable

As of April 24, 2023, we had 745,083 shares available for grant under the 2022 Plan. If the Amended 2022 Plan and the additional share reserve of 6,069,000 shares is approved by our stockholders, we will have 6,814,083 shares available for grant under the Amended 2022 Plan immediately after the Annual Meeting (based on shares available as of April 24, 2023). We anticipate this to be a pool of shares necessary for retaining and motivating employees, consultants and directors. If the Amended 2022 Plan is not approved by our stockholders, the 2022 Plan will continue in effect, but we will be extremely limited in the grants that we will be able to make, which could place us in a disadvantageous position as compared with our competitors, resulting in lack of employee retention and difficulty recruiting key positions.

We Manage Our Equity Incentive Award Use Carefully, and Dilution Is Reasonable

We continue to believe that equity awards are a vital part of our overall compensation program. However, we recognize that equity awards dilute existing stockholders, and, therefore, we must responsibly manage the growth of our equity compensation program. We are committed to effectively monitoring our equity compensation share reserve, including our “burn rate,” to ensure that we maximize stockholders’ value by granting the appropriate number of equity incentive awards necessary to attract, reward, and retain employees. The tables below show our overhang and burn rate information.

Key Plan Features

The Amended 2022 Plan includes provisions that are designed to protect our stockholders’ interests and to reflect corporate governance best practices including:

•

Repricing is not allowed without stockholder approval . The Amended 2022 Plan prohibits the repricing of outstanding stock options and stock appreciation rights and the cancelation of any outstanding stock options or stock appreciation rights that have an exercise or strike price greater than the then-current fair market value of our shares in exchange for cash or other stock awards under the Amended 2022 Plan without prior stockholder approval.

•

Stockholder approval is required for additional shares . The Amended 2022 Plan does not contain an annual “evergreen” provision. The Amended 2022 Plan authorizes a fixed number of shares, so that stockholder approval is required to issue any additional shares, allowing our stockholders to have direct input on our equity compensation programs.

•

Fungible share counting structure . The Amended 2022 Plan contains a “fungible share counting” structure, whereby the number of shares of our common stock available for issuance under the Amended 2022 Plan will be reduced by: (i) one share for each share issued pursuant to an Appreciation Award; and (ii) 1.14 shares for each share issued pursuant to a Full Value Award. This structure helps to ensure that we are using the share reserve effectively and with regard to the value of each type of equity award.

•

No liberal share counting . The following shares will not become available again for issuance under the Amended 2022 Plan: (i) shares that are reacquired or withheld (or not issued) by us to satisfy the exercise or strike price of an Appreciation Award or the purchase price of a Full Value Award; (ii) shares that are reacquired or withheld (or not issued) by us to satisfy a tax withholding obligation in

TABLE OF CONTENTS

connection with an Appreciation Award or Full Value Award; (iii) shares repurchased by us on the open market with the proceeds of the exercise or strike price of an Appreciation Award or the purchase price of a Full Value Award; and (iv) in the event that a stock appreciation right is settled in shares of common stock, the gross number of shares of common stock subject to the award.

•

Minimum vesting provision . No award may vest (and/or, if applicable, be exercisable) until at least 12 months following the date of grant of the award; provided, however, that up to 5% of the share reserve may be subject to awards that do not meet such vesting (and/or, if applicable, exercisability) requirements.

•

Restrictions on dividends . The Amended 2022 Plan provides that (i) no dividends or dividend equivalents may be paid with respect to any shares of our common stock subject to an equity award before the date such shares have vested, (ii) any dividends or dividend equivalents that are credited with respect to any such shares will be subject to all of the terms and conditions applicable to such shares under the terms of the applicable equity award agreement (including any vesting conditions), and (iii) any dividends or dividend equivalents that are credited with respect to any such shares will be forfeited to us on the date such shares are forfeited to or repurchased by us due to a failure to vest.

•

Specific disclosure of equity award vesting upon a corporate transaction or change in control . The Amended 2022 Plan specifically provides that in the event of a corporate transaction or change in control of the Company (each, a “Transaction”), if the surviving or acquiring corporation (or its parent company) does not assume or continue outstanding equity awards under the Amended 2022 Plan, or substitute similar equity awards for such outstanding equity awards, then with respect to any such equity awards that have not been assumed, continued or substituted and that are held by participants whose continuous service has not terminated prior to the Transaction, the vesting of such equity awards will be accelerated in full (and with respect to any performance-based equity awards, vesting will be deemed to be satisfied at the target level of performance).

•

Limit on non-employee director compensation . The aggregate value of all cash and equity-based compensation paid or granted by us to any individual for service as a non-employee director of our Board with respect to any fiscal year of the Company will not exceed (i) $900,000 in total value or (ii) in the event such non-employee director is first appointed or elected to the Board during such fiscal year, $1,400,000 in total value, in each case calculating the value of any equity awards based on the grant date fair value of such equity awards for financial reporting purposes.

•

No discounted stock options or stock appreciation rights . All stock options and stock appreciation rights must have an exercise price equal to or greater than the fair market value of our shares on the date the stock option or stock appreciation right is granted.

•

Awards subject to forfeiture/clawback . Awards granted under the Amended 2022 Plan will be subject to recoupment in accordance with our clawback policy that we adopted in May 2022. In the event that we are required to prepare a material restatement of our financials for a reporting period, the clawback policy generally allows us to seek to recover the portion of any incentive compensation that vested, or was granted to or earned by any current or former executive officer, in the 12 months prior to the restatement, in excess of the amount that the executive officer would otherwise have received based on the restated financial results. For purposes of the policy, “incentive compensation” includes any cash- or equity-based compensation that is granted, earned or vested based in whole or part on the attainment of a financial reporting measure. In addition, we may impose other clawback, recovery or recoupment provisions in an award agreement, including a reacquisition right in respect of previously acquired shares or other cash or property upon the occurrence of cause. Furthermore, upon finalization of relevant stock exchange rules regarding clawback policies, we will adopt an updated policy to comply with such requirements.

•

Administration by independent committee . The Amended 2022 Plan will be administered by the members of our Compensation Committee, all of whom are “non-employee directors” within the meaning of Rule 16b-3 under the Exchange Act and “independent” within the meaning of the Nasdaq listing standards.

TABLE OF CONTENTS

Description of the Amended 2022 Plan

The material features of the Amended 2022 Plan are described below. The following description of the Amended 2022 Plan is a summary only and is qualified in its entirety by reference to the complete text of the Amended 2022 Plan. Stockholders are urged to read the actual text of the Amended 2022 Plan in its entirety, which is appended as Appendix A to the copy of this proxy statement filed with the SEC, which may be accessed from the SEC’s website at www.sec.gov.

General. The Amended 2022 Plan provides for the grant of incentive stock options to our employees and employees of certain affiliates, and for the grant of nonstatutory stock options, stock appreciation rights, restricted stock awards, restricted stock unit awards, performance stock awards, performance cash awards, and other forms of stock awards to our employees, directors and consultants and the employees and consultants of our affiliates.

Authorized Shares and Share Counting Provisions. Subject to adjustment for certain changes in our capitalization, the aggregate number of shares of our common stock that may be issued under the Amended 2022 Plan will not exceed the sum of (i) 6,069,000 new shares, plus (ii) the 1,928,000 shares originally reserved under the 2022 Plan, plus (iii) the number of unallocated shares remaining available for grant under the LTIP as of the original effective date of the 2022 Plan, plus (iv) the Prior Plans’ Returning Shares, as such shares become available from time to time. The number of shares available for issuance under the Amended 2022 Plan will be reduced by: (a) one share for each share issued pursuant to an Appreciation Award; and (b) 1.14 shares for each share issued pursuant to a Full Value Award. The number of shares available for issuance under the Amended 2022 Plan will be increased by: (A) one share for each share subject to an Appreciation Award that returns from the LTIP, Inducement Plan or Amended 2022 Plan; and (B) 1.14 shares for each Prior Plans’ Returning Share or Amended 2022 Plan Returning Share (as defined below) subject to a Full Value Award.

The aggregate maximum number of shares of Common Stock that may be issued pursuant to the exercise of Incentive Stock Options is 37,200,000 shares.

The following actions will not result in an issuance of shares under the Amended 2022 Plan and accordingly do not reduce the number of shares subject to the share reserve and available for issuance under the Amended 2022 Plan: (i) the expiration or termination of any portion of an award without the shares covered by such portion of the award having been issued; or (ii) the settlement of any portion of an award granted under the Amended 2022 Plan in cash.

The following shares of our common stock (collectively, the “Amended 2022 Plan Returning Shares”) will become available again for issuance under the Amended 2022 Plan: any shares that are forfeited back to or repurchased by the Company because of a failure to meet a contingency or condition required for the vesting of such shares;

The following shares of our common stock will not become available again for issuance under the Amended 2022 Plan: (1) any shares that are reacquired or withheld (or not issued) by the Company to satisfy the exercise or strike price of an Appreciation Award or the purchase price of a Full Value Award; (2) any shares that are reacquired or withheld (or not issued) by the Company to satisfy a tax withholding obligation in connection with an Appreciation Award or a Full Value Award; (3) any shares repurchased by us on the open market with the proceeds of the exercise or strike price of an Appreciation Award or the purchase price of a Full Value Award; and (4) in the event that a stock appreciation right is settled in shares of common stock, the gross number of shares of common stock subject to such award.

Plan Administration. Our Board, or a duly authorized committee of our Board, administers the Amended 2022 Plan. Our Board may also delegate to one or more of our officers the authority to (1) designate employees (other than officers) to receive specified stock awards and (2) determine the number of shares subject to such stock awards. Under the Amended 2022 Plan, our Board has the authority to determine the terms of awards, including recipients, the exercise, purchase or strike price of stock awards, if any, the number of shares subject to each stock award, the fair market value of a share, the vesting schedule applicable to the awards, together with any vesting acceleration, the form of consideration, if any, payable upon exercise or settlement of the award and the terms of the award agreements.

TABLE OF CONTENTS

No Repricing Without Stockholder Approval . Under the Amended 2022 Plan, the plan administrator does not have the authority to reprice any outstanding stock option or stock appreciation right by reducing the exercise or strike price of the stock option or stock appreciation right or to cancel any outstanding stock option or stock appreciation right that has an exercise or strike price greater than the then-current fair market value of our common stock in exchange for cash or other stock awards without obtaining the approval of our stockholders. Such approval must be obtained within 12 months prior to such an event.

Minimum Vesting Requirements. Under the Amended 2022 Plan, no award may vest (and/or, if applicable, be exercisable) until at least 12 months following the date of grant of the award; provided, however, that up to 5% of the share reserve may be subject to awards that do not meet such vesting (and/or, if applicable, exercisability) requirements.

Dividends and Dividend Equivalents. The Amended 2022 Plan provides that dividends or dividend equivalents may be paid or credited with respect to any shares of our common stock subject to an award, as determined by the plan administrator and contained in the applicable award agreement; provided, however , that (i) no dividends or dividend equivalents may be paid with respect to any such shares before the date such shares have vested, (ii) any dividends or dividend equivalents that are credited with respect to any such shares will be subject to all of the terms and conditions applicable to such shares under the terms of the applicable award agreement (including any vesting conditions), and (iii) any dividends or dividend equivalents that are credited with respect to any such shares will be forfeited to us on the date such shares are forfeited to or repurchased by us due to a failure to vest.

Stock Options. Incentive stock options and nonstatutory stock options are granted pursuant to stock option agreements adopted by the plan administrator. The plan administrator determines the exercise price for stock options, within the terms and conditions of the Amended 2022 Plan, provided that the exercise price of a stock option generally cannot be less than 100% of the fair market value of a share on the date of grant. Options granted under the Amended 2022 Plan vest at the rate specified in the stock option agreement as determined by the plan administrator.

Restricted Stock Unit Awards. Restricted stock unit awards are granted pursuant to restricted stock unit award agreements adopted by the plan administrator. Restricted stock unit awards may be granted in consideration for any form of legal consideration that may be acceptable to our Board, or a duly authorized committee of our Board, and permissible under applicable law. A restricted stock unit award may be settled by cash, delivery of stock, a combination of cash and stock as deemed appropriate by the plan administrator or in any other form of consideration set forth in the restricted stock unit award agreement. Except as otherwise provided in the applicable award agreement, restricted stock units that have not vested will be forfeited upon the participant’s cessation of continuous service for any reason.

Restricted Stock Awards. Restricted stock awards are granted pursuant to restricted stock award agreements adopted by the plan administrator. A restricted stock award may be awarded in consideration for cash, check, bank draft or money order, past services to us or any other form of legal consideration that may be acceptable to our Board, or a duly authorized committee of our Board, and permissible under applicable law. The plan administrator determines the terms and conditions of restricted stock awards, including vesting and forfeiture terms. If a participant’s service relationship with us ceases for any reason, we may receive through a forfeiture condition or a repurchase right any or all of the shares held by the participant that have not vested as of the date the participant terminates service with us.

Stock Appreciation Rights. Stock appreciation rights are granted pursuant to stock appreciation grant agreements adopted by the plan administrator. The plan administrator determines the purchase price or strike price for a stock appreciation right, which generally cannot be less than 100% of the fair market value of a share on the date of grant. A stock appreciation right granted under the Amended 2022 Plan vests at the rate specified in the stock appreciation right agreement as determined by the plan administrator.

Performance Awards. The Amended 2022 Plan permits the grant of performance-based stock and cash awards. Our Compensation, Nominating and Corporate Governance Committee may structure awards so that the stock or cash will be issued or paid only following the achievement of certain pre-established performance goals during a designated performance period.

TABLE OF CONTENTS

Other Stock Awards. The plan administrator may grant other awards based in whole or in part by reference to our shares. The plan administrator will set the number of shares under the stock award and all other terms and conditions of such awards.

Changes to Capital Structure. In the event there is a specified type of change in our capital structure, such as a stock split, reverse stock split or recapitalization, appropriate adjustments will be made to (1) the class and maximum number of shares reserved for issuance under the Amended 2022 Plan, (2) the class and maximum number of shares that may be issued upon the exercise of incentive stock options, (3) the class and maximum number of shares subject to stock awards that can be granted in a calendar year and (4) the class and number of shares and exercise price, strike price or purchase price, if applicable, of all outstanding stock awards.

Corporate Transaction and Change in Control

The following provisions will apply to outstanding awards under the Amended 2022 Plan in the event of a corporate transaction (as defined in the Amended 2022 Plan and described below) or a change in control (as defined in the Amended 2022 Plan and described below) unless otherwise provided in the instrument evidencing the award, in any other written agreement between us or one of our affiliates and the participant, or in our director compensation policy. For purposes of this Proposal 2, the term “Transaction” will mean such corporate transaction or change in control.

In the event of a Transaction, any surviving or acquiring corporation (or its parent company) may assume or continue any or all outstanding awards under the Amended 2022 Plan, or may substitute similar stock awards for such outstanding awards (including, but not limited to, awards to acquire the same consideration paid to the stockholders of the Company pursuant to the Transaction), and any reacquisition or repurchase rights held by the Company in respect of shares issued pursuant to any outstanding awards under the Amended 2022 Plan may be assigned by the Company to the surviving or acquiring corporation (or its parent company).

In the event of a Transaction in which the surviving or acquiring corporation (or its parent company) does not assume or continue outstanding awards under the Amended 2022 Plan, or substitute similar stock awards for such outstanding awards, then with respect to any such awards that have not been assumed, continued or substituted and that are held by participants whose continuous service has not terminated prior to the effective time of the Transaction (the “Current Participants”), the vesting (and exercisability, if applicable) of such awards will be accelerated in full (and with respect to any such awards that are subject to performance-based vesting conditions or requirements, vesting will be deemed to be satisfied at the target level of performance to a date prior to the effective time of the Transaction (contingent upon the closing or completion of the Transaction) as the plan administrator will determine, and such awards will terminate if not exercised (if applicable) prior to the effective time of the Transaction in accordance with the exercise procedures determined by the plan administrator, and any reacquisition or repurchase rights held by the Company with respect to such awards will lapse (contingent upon the closing or completion of the corporate transaction).

In the event any outstanding award under the Amended 2022 Plan held by a participant will terminate if not exercised prior to the effective time of a Transaction, the plan administrator may provide that the participant may not exercise such award but instead will receive a payment, in such form as may be determined by the plan administrator, equal in value to the excess, if any, of (i) the value of the property the participant would have received upon the exercise of such award immediately prior to the effective time of the Transaction, over (ii) any exercise price payable by the participant in connection with such exercise.

TABLE OF CONTENTS

For purposes of the Amended 2022 Plan, a “corporate transaction” generally will be deemed to occur in the event of the consummation of:

•

a sale or other disposition of all or substantially all of the consolidated assets of the Company and its subsidiaries;

•

a sale or other disposition of at least 50% of the outstanding securities of the Company;

•

a merger, consolidation or similar transaction following which the Company is not the surviving corporation; or

•

a merger, consolidation or similar transaction following which the Company is the surviving corporation but the shares of common stock outstanding immediately preceding the merger, consolidation or similar transaction are converted or exchanged by virtue of the merger, consolidation or similar transaction into other property, whether in the form of securities, cash or otherwise.

For purposes of the Amended 2022 Plan, a “change in control” generally will be deemed to occur in the event:

•

a person, entity or group acquires, directly or indirectly, our securities representing more than 50% of the combined voting power of our then outstanding securities, other than by virtue of a merger, consolidation, or similar transaction;

•

there is consummated a merger, consolidation, or similar transaction and, immediately after the consummation of such transaction, our stockholders immediately prior thereto do not own, directly or indirectly, more than 50% of the combined outstanding voting power of the surviving entity or the parent of the surviving entity in substantially the same proportions as their ownership of our outstanding voting securities immediately prior to such transaction;

•

there is consummated a sale or other disposition of all or substantially all of our consolidated assets, other than a sale or other disposition to an entity in which more than 50% of the entity’s combined voting power is owned by our stockholders in substantially the same proportions as their ownership of our outstanding voting securities immediately prior to such sale or other disposition; or

•

a majority of our Board becomes comprised of individuals whose nomination, appointment, or election was not approved by a majority of the Board members or their approved successors.

Transferability. A participant may not transfer stock awards under the Amended 2022 Plan other than by will, the laws of descent and distribution or as otherwise provided under the Amended 2022 Plan.

Plan Amendment or Termination. Our Board has the authority to amend, suspend or terminate the Amended 2022 Plan, provided that such action does not materially impair the existing rights of any participant without such participant’s written consent. Certain material amendments also require the approval of our stockholders. No incentive stock options may be granted after the tenth anniversary of the date our Board adopted the Amended 2022 Plan. No stock awards may be granted under the Amended 2022 Plan while it is suspended or after it is terminated.

U.S. Federal Income Tax Consequences

The information set forth below is a summary only and does not purport to be complete. The information is based upon current federal income tax rules and therefore is subject to change when those rules change. Because the tax consequences to any recipient may depend on his or her particular situation, each recipient should consult the recipient’s tax adviser regarding the federal, state, local, and other tax consequences of the grant or exercise of an award or the disposition of stock acquired as a result of an award. The Amended 2022 Plan is not qualified under the provisions of Section 401(a) of the Code and is not subject to any of the provisions of the Employee Retirement Income Security Act of 1974.

Nonstatutory Stock Options

Generally, there is no taxation upon the grant of a nonstatutory stock option if the stock option is granted with an exercise price equal to the fair market value of the underlying stock on the grant date. On exercise, an optionholder will recognize ordinary income equal to the excess, if any, of the fair market value on

TABLE OF CONTENTS

the date of exercise of the stock over the exercise price. If the optionholder is employed by us or one of our affiliates, that income will be subject to withholding taxes. We will generally be entitled to a tax deduction equal to the taxable ordinary income realized by the optionholder.

Incentive Stock Options

The Amended 2022 Plan provides for the grant of stock options that qualify as “incentive stock options,” as defined in Section 422 of the Internal Revenue Code of 1986, as amended (the “Code”). Under the Code, an optionholder generally is not subject to ordinary income tax upon the grant or exercise of an incentive stock option (“ISO”) (although, in certain circumstances, there may be an item of adjustment included for alternative minimum tax purposes). If the optionholder holds a share received on exercise of an ISO for more than two years from the date the stock option was granted and more than one year from the date the stock option was exercised, which is referred to as the required holding period, the difference, if any, between the amount realized on a sale or other taxable disposition of that share and the holder’s tax basis in that share will be long-term capital gain or loss. If, however, an optionholder disposes of a share acquired on exercise of an ISO before the end of the required holding period, which is referred to as a disqualifying disposition, the optionholder generally will recognize ordinary income in the year of the disqualifying disposition equal to the excess, if any, of the fair market value of the share on the date the ISO was exercised over the exercise price.

We are not allowed an income tax deduction with respect to the grant or exercise of an ISO or the disposition of a share acquired on exercise of an ISO after the required holding period. If there is a disqualifying disposition of a share, however, we are generally allowed a deduction in an amount equal to the ordinary income includible in income by the optionholder.

Restricted Stock Awards

Generally, the recipient of a restricted stock award will recognize ordinary income at the time the stock is received equal to the excess, if any, of the fair market value of the stock received over any amount paid by the recipient in exchange for the stock. If, however, the stock is not vested when it is received (for example, if the employee is required to work for a period of time in order to have the right to sell the stock), the recipient generally will not recognize income until the stock becomes vested, at which time the recipient will recognize ordinary income equal to the excess, if any, of the fair market value of the stock on the date it becomes vested over any amount paid by the recipient in exchange for the stock. A recipient may, however, file an election with the Internal Revenue Service, within 30 days following his or her receipt of the stock award, to recognize ordinary income, as of the date the recipient receives the award, equal to the excess, if any, of the fair market value of the stock on the date the award is granted over any amount paid by the recipient for the stock. We will generally be entitled to a tax deduction equal to the taxable ordinary income realized by the recipient of the stock award.

Restricted Stock Unit Awards

Generally, the recipient of a stock unit structured to conform to the requirements of Section 409A of the Code or an exception to Section 409A of the Code will recognize ordinary income at the time the stock is delivered equal to the excess, if any, of the fair market value of the shares received over any amount paid by the recipient in exchange for the shares.

We will generally be entitled to a tax deduction equal to the taxable ordinary income realized by the recipient of the stock award.

Stock Appreciation Rights

We may grant under the Amended 2022 Plan stock appreciation rights separate from any other award or in tandem with other awards under the Amended 2022 Plan.

Where the stock appreciation rights are granted with a strike price equal to the fair market value of the underlying stock on the grant date, the recipient will recognize ordinary income equal to the fair market value of the stock or cash received upon such exercise. We will generally be entitled to a tax deduction equal to the taxable ordinary income realized by the recipient of the stock appreciation right.

TABLE OF CONTENTS

Section 162(m) Limitations

Under Section 162(m) of the Code (“Section 162(m)”), compensation paid to each of the Company’s “covered employees” that exceeds $1 million per taxable year is generally non-deductible. Although the Compensation Committee will continue to consider tax implications as one factor in determining executive compensation, the Compensation Committee also looks at other factors in making its decisions and retains the flexibility to provide compensation for the Company’s named executive officers in a manner consistent with the goals of the Company’s executive compensation program and the best interests of the Company and its stockholders, which may include providing for compensation that is not deductible by the Company due to the deduction limit under Section 162(m).

New Plan Benefits

We cannot currently determine the benefits or number of shares subject to awards that may be granted in the future to executive officers, directors, and employees under the Amended 2022 Plan. We do not presently have any current plans, proposals or arrangements, written or otherwise, to issue any of the newly available authorized shares under the Amended 2022 Plan, except as set forth below with respect to non-employee directors. As of March 31, 2023, we had 135 employees, six consultants and seven non-employee directors who would be eligible to receive grants under the 2022 Plan.

PROPOSAL 3

RATIFICATION OF SELECTION OF INDEPENDENT REGISTERED PUBLIC
ACCOUNTING FIRM

The Audit Committee has selected CohnReznick LLP as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2023 and has further directed that management submit the selection of its independent registered public accounting firm for ratification by the stockholders at the Annual Meeting. CohnReznick LLP has audited the Company’s financial statements since the financial year ended December 31, 2019. Representatives of CohnReznick LLP are expected to be present at the Annual Meeting. They will have an opportunity to make a statement if they so desire and will be available to respond to appropriate questions.

Neither the Company’s Amended and Restated Bylaws nor other governing documents or law require stockholder ratification of the selection of CohnReznick LLP as the Company’s independent registered public accounting firm. However, the Audit Committee is submitting the selection of CohnReznick 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 or not to retain that firm. Even if the selection is ratified, the Audit Committee in its discretion may direct the appointment of different independent auditors at any time during the year if they determine that such a change would be in the best interests of the Company and its stockholders.

The affirmative vote of the holders of a majority of the shares present in person or represented by proxy and entitled to vote on the matter at the Annual Meeting will be required to ratify the selection of CohnReznick LLP. Abstentions on this proposal will be counted towards the vote total and will have the same effect as an “Against” vote. Since brokers have authority to vote on your behalf with respect to this proposal, we do not expect broker non-votes on this proposal.

Principal Accountant Fees And Services

The following table represents aggregate fees billed to the Company for the fiscal years ended December 31, 2022 and 2021 by CohnReznick LLP, the Company’s principal accountant.

	Fiscal Year Ended December 31,
	2022			2021
	(in thousands)
Audit Fees		$	306		$	482
Tax Fees			33			45
Total Fees		$	339		$	526

Audit fees consist of fees billed for professional services provided in connection with the audit of our annual financial statements, the review of our quarterly financial statements, and audit services that are normally provided by the independent registered public accounting firm in connection with regulatory filings. For 2021, the audit fees also include fees for professional services provided in connection with our initial public offering in 2021.

Tax fees consist of fees for tax compliance, consultation and related matters.

All fees described above were pre-approved by the Audit Committee.

Pre-Approval Policies And Procedures

The Audit Committee has adopted a policy and procedures for the pre-approval of audit and non-audit services rendered by the Company’s independent registered public accounting firm, CohnReznick LLP. The policy generally pre-approves specified services in the defined categories of audit services, audit-related services and tax services up to specified amounts. Pre-approval may also be given as part of the Audit Committee’s approval of the scope of the engagement of the independent auditor or on an individual, explicit, case-by-case basis before the independent auditor is engaged to provide each service. The pre-approval of services may be

TABLE OF CONTENTS

delegated to one or more of the Audit Committee’s members, but the decision must be reported to the full Audit Committee at its next scheduled meeting.

The Audit Committee has determined that the rendering of services other than audit services by CohnReznick LLP is compatible with maintaining the principal accountant’s independence.

The Board Of Directors Recommends
A Vote In Favor Of Proposal 3.

Amounts reported represent the aggregate grant date fair value of the stock options granted to our named executive officers during the indicated year, computed in accordance with Financial Accounting Standard Board Accounting Standards Codification Topic 718 (“ ASC 718 ”). The fair value of each stock option grant is estimated on the date of grant using the Black-Scholes option pricing model. The assumptions used in calculating the grant date fair value of the stock options reported in this column are set forth in Note 2 to our audited financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2022. This amount does not reflect the actual economic value that may be realized by the named executive officer upon the exercise of the options or the sale of the underlying shares.

Narrative to the Summary Compensation Table

We review compensation annually for all employees, including our executives. In setting executive base salaries and bonuses and granting equity incentive awards, we consider compensation for comparable positions in the market, the historical compensation levels of our executives, individual performance as compared to our expectations and objectives, our desire to motivate our employees to achieve short- and long-term results that are in the best interests of our stockholders and a long-term commitment to our company. We do not target a specific competitive position or a specific mix of compensation among base salary, bonus or long-term incentives.

TABLE OF CONTENTS

The Compensation Committee of our Board determines our executives’ compensation. Our Compensation Committee typically reviews and discusses management’s proposed compensation with the Chief Executive Officer for all executives other than the Chief Executive Officer, which is recommended by our Compensation Committee. Based on those discussions and its discretion, the Compensation Committee then recommends the compensation for each executive officer. Our Compensation Committee, without members of management present, discusses and ultimately approves the compensation of our executive officers, with the exception of the Chief Executive Officer’s compensation, which is recommended to the full board. The Compensation Committee retained Arnosti Consulting, Inc., a compensation consulting firm, to evaluate and make recommendations with respect to our executive compensation program decisions for 2022.

Annual Performance Bonuses

Each of our executive officers is eligible to receive performance bonus under our annual incentive compensation program. Under our 2022 annual incentive compensation program, each of our named executive officers was eligible to receive a cash incentive payment equal to (1) his target incentive, as a percentage of annual base salary, multiplied by (2) the percentage achievement of certain 2022 corporate goals established by our Compensation Committee in its sole discretion, and approved by our Board, subject to the named executive officer remaining employed by us through the payment date.

Mr. Doerfler’s target incentive was set at 85% of his annual base salary, Dr. Sumen’s at 40% of his annual base salary, and Mr. Masoud’s at 40% of his annual base salary. The corporate goals used for purposes of the 2022 annual incentive compensation program included revenue, EBITDA, and targets related to product development launches, manufacturing and engineering, and partnership licensing. Our Compensation Committee determined that the percentage achievement of the applicable corporate goals was 100% for each of the named executive officers. As a result, our Compensation Committee approved a cash incentive payment for each named executive officer in the amounts reflected above in the “Non-Equity Incentive Plan Compensation” column of the Summary Compensation Table. Each named executive’s cash incentive payment for 2022 was paid in the first quarter of 2023.

Long-Term Incentives

In March 2022, we granted stock options to Mr. Doerfler and Mr. Masoud to purchase 500,000 shares and 142,000 shares, respectively, and in April 2022, following Dr. Sumen’s hire in March 2022, we granted options to Dr. Sumen to purchase 500,000 shares.

In May 2022, our board of directors adopted, and in June 2022 our stockholders approved, the 2022 Plan and in March 2023, we made annual grants of stock options to Mr. Doerfler, Mr. Masoud and Dr. Sumen to purchase 400,000 shares, 120,000 shares and 120,000 shares, respectively.

With respect to each of the foregoing stock option grants, 25% of the shares underlying the options vest on the first anniversary of the date of grant and the remaining shares underlying the option vest in 36 equal monthly installments thereafter, subject to each officer’s continuous service with us at each vesting date.

Retirement Benefits and Other Compensation

Health and Welfare and Retirement Benefits

All of our current named executive officers are eligible to participate in our employee benefit plans, including our medical, dental, vision, disability and life insurance plans, in each case on the same basis as all of our other employees. We do not provide perquisites or personal benefits to our named executive officers other than those provided generally to all employees. In connection with Dr. Sumen’s appointment as our Chief Scientific Officer, we provided him with relocation assistance with a value of approximately $20,000.

401(k) Plan

We maintain a tax-qualified retirement plan, the 401(k) Plan, that provides eligible employees in the United States with an opportunity to save for retirement on a tax-advantaged basis. Under the 401(k) Plan, we may provide matching and other discretionary contributions. We currently match employee contributions equal to 50% of the first 10% of salary deferral contributions, with a maximum company contribution of 5%

TABLE OF CONTENTS

of the employee’s eligible compensation. Pre-tax contributions are allocated to each participant’s individual account and are then invested in selected investment alternatives according to the participants’ directions. The 401(k) Plan is intended to qualify under Sections 401(a) and 501(a) of the Internal Revenue Code.

Outstanding Equity Awards at Fiscal Year End

Employment Agreements; Potential Payments Upon Termination or Change in Control

We have entered into severance agreements with each of the NEOs in connection with his employment with us, which sets forth the terms and conditions of his specified payments and benefits in connection with a termination of employment in certain circumstances. In each case, the officer must sign and not revoke a release of claims in our favor in order to receive these payments and benefits. Our goal in providing these severance and change in control payments and benefits is to offer sufficient cash continuity protection such that the NEOs will focus their full time and attention on the requirements of the business rather than the potential implications of a qualifying employment termination or change in control for their respective positions. We prefer to have certainty regarding the potential severance amounts payable to the NEOs, rather than negotiating severance at the time that an NEO’s employment terminates. We have also determined that accelerated vesting provisions with respect to outstanding equity awards in connection with a qualifying termination of employment in certain circumstances are appropriate because they encourage our NEOs to stay focused on the business in those circumstances, rather than focusing on the potential implications of the termination of employment for them personally. The material terms of the severance agreements we have entered into with our NEOs are summarized below.

Doug Doerfler

We entered into a severance agreement dated July 20, 2021, setting forth the terms of Mr. Doerfler’s severance eligibility. Under Mr. Doerfler’s severance agreement, if he is terminated by us other than for “cause” (as defined in the severance agreement), or if he resigns for “good reason” (as defined in the severance agreement), and if such termination or resignation occurs on the date of or within 24 months following a “change of control” (as defined in the severance agreement), then Mr. Doerfler will be eligible to receive (i) payment of his monthly base salary (calculated as his total base salary during the 12 month period prior to his date of termination divided by 12) for the 18 months following his departure (less applicable tax withholdings), (ii) 75% of his “target bonus” (as defined in the severance agreement) (less applicable tax withholdings) paid in monthly installments over 18 months, (iii) COBRA premium coverage for up to 18 months, and (iv) full acceleration of the vesting of the unvested shares subject to his outstanding stock options.

Under Mr. Doerfler’s severance agreement, if he is terminated by us other than for “cause,” or if he resigns for “good reason,” and if such termination or resignation occurs at any time prior to a “change of control,” then Mr. Doerfler will be eligible to receive (i) payment of his monthly base salary (calculated as his total base salary during the 12 month period prior to his date of termination divided by 12) for the 12 months following his departure (less any amounts paid to Mr. Doerfler during such 12 month period under our Short Term or Long Term Disability Plan, and less applicable tax withholdings), (ii) COBRA premium coverage for up to 12 months, and (iii) if the termination or resignation occurs within 180 days prior to a “change of

Maher Masoud

We entered into a severance agreement dated January 11, 2021, setting forth the terms of Mr. Masoud’s severance eligibility.

Director Compensation

We have historically provided our non-employee directors with an annual cash retainer as well as additional annual retainers for service as chair of the Board and service as chair or member of the Board’s committees. The fees for committee service are in addition to the annual cash retainer for Board service. Members of committee can receive either a chair or a member retainer for service on the committee, but not both.

In addition to annual cash retainers, in accordance with our equity grant policy, our non-employee directors are granted options to purchase shares of our common stock under our 2022 Plan in an amount determined by our Board annually. In June 2022, at the time of our 2022 annual meeting of stockholders, each of our non-employee directors was granted an option to purchase 26,900 shares of our common stock. In March 2023, Dr. Al-Wakeel and Ms. Hemrajani were each granted an additional option to purchase 40,000 shares of our common stock. Dr. Al-Wakeel and Ms. Hemrajani joined our Board shortly before our U.S. initial public offering in August 2021, and it was determined that the equity awards issued to them at the commencement of their service on the Board was below those of our peer companies listed on Nasdaq and therefore that an upward adjustment was appropriate in the form of a new grant. From time to time, our non-employee directors are also reimbursed upon request for out-of-pocket expenses incurred in connection with their attendance at Board meetings.

2022 Director Compensation Table

The following table sets forth information regarding the compensation earned for service on our Board in 2022 by our non-employee directors.

TRANSACTIONS WITH RELATED PERSONS AND INDEMNIFICATION

Related-Person Transactions Policy and Procedures

We have adopted a policy that our executive officers, directors, nominees for election as a director, beneficial owners of more than 5% of any class of our common stock and any members of the immediate family of any of the foregoing persons are not permitted to enter into a related person transaction with us without the approval or ratification of our Board or our Audit Committee. Any request for us to enter into a transaction with an executive officer, director, nominee for election as a director, beneficial owner of more than 5% of any class of our common stock or any member of the immediate family of any of the foregoing persons, in which the amount involved exceeds $120,000 and such person would have a direct or indirect interest, must be presented to our Board or our Audit Committee for review, consideration and approval. In approving or rejecting any such proposal, our Board or our Audit Committee is to consider the material facts of the transaction, including whether the transaction is on terms no less favorable than terms generally available to an unaffiliated third party under the same or similar circumstances and the extent of the related person’s interest in the transaction.

The related person transactions policy also covers related party transactions under the AIM Rules for Companies published by London Stock Exchange plc (the “ AIM Rules ”), which contains a different definition of a related party to the definition of a related person set out above for U.S. purposes. The AIM Rules require that any transaction with a related party (pursuant to the definition in the AIM Rules) that exceeds 5% in any of the class tests set out in the AIM Rules, taking into account certain provisions relating to aggregation of transactions, should be announced without delay as soon as the terms of the transaction are agreed, and that the announcement should include certain specified information including a statement that our directors (with the exception of any director who is involved in the transaction as a related party) consider, having consulted with our nominated adviser for AIM, that the terms of the transaction are fair and reasonable insofar as our stockholders are concerned.

Certain Related-Person Transactions

Except as described below, there have been no transactions since January 1, 2022 to which we have been a participant in which the amount involved exceeded or will exceed $120,000, and in which any of our directors, executive officers or holders of more than five percent of our capital stock, or any members of their immediate family, had or will have a direct or indirect material interest, other than compensation arrangements that are described under “Executive Compensation” and “Director Compensation.” For a description of severance and change in control arrangements that we have entered into with some of our executive officers, see “Executive Compensation — Potential Payments upon Termination or Change in Control.”

Novavax Sublease

In November 2011, we entered into a Lease Agreement, as subsequently amended or restated (the “ Lease Agreement ”) with Novavax, Inc. (“ Novavax ”), covering the sublease of approximately 19,000 square feet of office and laboratory space. The sublease is currently set to expire in October 2023. Richard Douglas, the chairman of our Board, is a member of the board of directors of Novavax, and Stanley Erck, a member of our Board, was the chief executive officer of, and a director of, Novavax until January 2023. Under the terms of the Lease Agreement, we paid Novavax $296,300 for the year ended December 31, 2022.

Indemnification Agreements

We provide indemnification for our directors and executive officers so that they will be free from undue concern about personal liability in connection with their service to the Company. Under our Bylaws, we are required to indemnify our directors and executive officers to the extent not prohibited under Delaware law. We have also entered into indemnity agreements with certain officers and directors. These agreements provide, among other things, that we will indemnify the officer or director, under the circumstances and to the extent provided for in the agreement, for expenses, damages, judgments, fines and settlements he or she may be required to pay in actions or proceedings which he or she is or may be made a party by reason of his or her position as a director, officer or other agent of the Company, and otherwise to the fullest extent permitted under Delaware law and our Bylaws.

TABLE OF CONTENTS

HOUSEHOLDING OF PROXY MATERIALS

The SEC has adopted rules that permit companies and intermediaries (e.g., brokers) to satisfy the delivery requirements for Notices of Internet Availability of Proxy Materials or other Annual Meeting materials with respect to two or more stockholders sharing the same address by delivering a single Notice of Internet Availability of Proxy Materials or other Annual Meeting materials addressed to those stockholders. This process, which is commonly referred to as “householding,” potentially means extra convenience for stockholders and cost savings for companies.

This year, a number of brokers with account holders who are MaxCyte, Inc. stockholders will be “householding” the Company’s proxy materials. A single set of Annual Meeting material will be delivered to multiple stockholders sharing an address unless contrary instructions have been received from the affected stockholders. Once you have received notice from your broker that they will be “householding” communications to your address, “householding” will continue until you are notified otherwise or until you revoke your consent. If, at any time, you no longer wish to participate in “householding” and would prefer to receive a separate set of Annual Meeting materials, please notify your broker or MaxCyte. Direct your written request to MaxCyte, Inc., Attn: Corporate Secretary; 9713 Key West Avenue, Suite 400, Rockville, Maryland 20850, Attention: Investor Relations . Stockholders who currently receive multiple copies of the Annual Meeting materials at their addresses and would like to request “householding” of their communications should contact their brokers.

OTHER MATTERS

TABLE OF CONTENTS

(i) Limit Applies to Common Stock Issued Pursuant to Awards. For clarity, the Share Reserve is a limit on the number of shares of Common Stock that may be issued pursuant to Awards and does not limit the granting of Awards, except that the Company will keep available at all times the number of shares of Common Stock reasonably required to satisfy its obligations to issue shares pursuant to such Awards. Shares may be issued in connection with a merger or acquisition as permitted by, as applicable, Nasdaq Listing Rule 5635(c), NYSE Listed Company Manual Section 303A.08, NYSE American Company Guide Section 711 or other applicable rule, and such issuance will not reduce the number of shares available for issuance under the Plan.

(ii) Actions that Do Not Constitute Issuance of Common Stock and Do Not Reduce Share Reserve. The following actions do not result in an issuance of shares under the Plan and accordingly do not reduce the number of shares subject to the Share Reserve and available for issuance under the Plan: (1) the expiration or termination of any portion of an Award without the shares covered by such portion of the Award having been issued; or (2) the settlement of any portion of an Award in cash (i.e., the Participant receives cash rather than shares of Common Stock).

(iii) Previously Issued Shares of Common Stock Available for Subsequent Issuance. The following shares of Common Stock (collectively, the “ 2022 Plan Returning Shares ”) previously issued pursuant to an Award will become available again for issuance under the Plan: any shares that are forfeited back to or repurchased by the Company because of a failure to meet a contingency or condition required for the vesting of such shares.

(iv) Previously Issued Shares of Common Stock Not Available for Subsequent Issuance. The following shares of Common Stock previously issued pursuant to an Award will not become available again for issuance under the Plan: (1) any shares that are reacquired or withheld (or not issued) by the Company to satisfy (i) the exercise or strike price of an Appreciation Award or (ii) the purchase price of a Full Value Award; (2) any shares that are reacquired or withheld (or not issued) by the Company to satisfy a tax withholding obligation in connection with an Appreciation Award or a Full Value Award; (3) any shares repurchased by the Company on the open market with the proceeds of (i) the exercise or strike price of an Appreciation Award or (ii) the purchase price of a Full Value Award; and (4) in the event that an SAR is settled in shares of Common Stock, the gross number of shares of Common Stock subject to such award.

E ligibility and L imitations .

(a) Eligible Award Recipients. Subject to the terms of the Plan, Employees, Directors and Consultants are eligible to receive Awards.

(b) Specific Award Limitations.

(ii) Incentive Stock Option $100,000 Limitation. To the extent that the aggregate fair market value (determined at the time of grant) of the shares of Common Stock with respect to which Incentive Stock Options are exercisable for the first time by any Optionholder during any calendar year (under all plans of the Company and any “parent corporation” or “subsidiary corporation” thereof, as such terms are defined in Sections 424(e) and (f) of the Code) exceeds $100,000 (or such other limit established in the Code), or any Incentive Stock Options otherwise do not comply with the rules governing Incentive Stock Options, the Options or portions thereof that exceed such limit (according to the order in which they were granted) or otherwise do not comply with such rules will be treated as Nonstatutory Stock Options, notwithstanding any contrary provision of the applicable Option Agreement(s).

A-2

TABLE OF CONTENTS

(iii) Limitations on Incentive Stock Options Granted to Ten Percent Stockholders. A Ten Percent Stockholder may not be granted an Incentive Stock Option unless (i) the exercise price of such Option is at least 110% of the Fair Market Value on the date of grant of such Option and (ii) the Option is not exercisable after the expiration of five years from the date of grant of such Option.

(iv) Limitations on Nonstatutory Stock Options and SARs. Nonstatutory Stock Options and SARs may not be granted to Employees, Directors and Consultants who are providing Continuous Service only to any “parent” of the Company (as such term is defined in Rule 405) unless the stock underlying such Awards is treated as “service recipient stock” under Section 409A because the Awards are granted pursuant to a corporate transaction (such as a spin off transaction) or unless such Awards otherwise comply with the distribution requirements of Section 409A.

(c) Aggregate Incentive Stock Option Limit. The aggregate maximum number of shares of Common Stock that may be issued pursuant to the exercise of Incentive Stock Options is the number of shares specified in Section 2(b).

(d) Non-Employee Director Compensation Limit. The aggregate value of all compensation granted or paid, as applicable, to any individual for service as a Non-Employee Director with respect to any fiscal year, including Awards granted and cash fees paid by the Company to such Non-Employee Director for his or her service as a Non-Employee Director, will not exceed (i) $900,000 in total value or (ii) in the event such Non-Employee Director is first appointed or elected to the Board during such fiscal year, $1,400,000 in total value, in each case calculating the value of any equity awards based on the grant date fair value of such equity awards for financial reporting purposes.

O ptions and S tock A ppreciation R ights .

Each Option and SAR will have such terms and conditions as determined by the Board. Each Option will be designated in writing as an Incentive Stock Option or Nonstatutory Stock Option at the time of grant; provided, however, that if an Option is not so designated, then such Option will be a Nonstatutory Stock Option, and the shares purchased upon exercise of each type of Option will be separately accounted for. Each SAR will be denominated in shares of Common Stock equivalents. The terms and conditions of separate Options and SARs need not be identical; provided, however, that each Option Agreement and SAR Agreement will conform (through incorporation of provisions hereof by reference in the Award Agreement or otherwise) to the substance of each of the following provisions:

(a) Term. Subject to Section 3(b) regarding Ten Percent Stockholders, no Option or SAR will be exercisable after the expiration of ten years from the date of grant of such Award or such shorter period specified in the Award Agreement.

(b) Exercise or Strike Price. Subject to Section 3(b) regarding Ten Percent Stockholders, the exercise or strike price of each Option or SAR will not be less than 100% of the Fair Market Value on the date of grant of such Award. Notwithstanding the foregoing, an Option or SAR may be granted with an exercise or strike price lower than 100% of the Fair Market Value on the date of grant of such Award if such Award is granted pursuant to an assumption of or substitution for another option or stock appreciation right pursuant to a Transaction and in a manner consistent with the provisions of Sections 409A and, if applicable, 424(a) of the Code.

(c) Exercise Procedure and Payment of Exercise Price for Options. In order to exercise an Option, the Participant must provide notice of exercise to the Plan Administrator in accordance with the procedures specified in the Option Agreement or otherwise provided by the Company. The Board has the authority to grant Options that do not permit all of the following methods of payment (or otherwise restrict the ability to use certain methods) and to grant Options that require the consent of the Company to utilize a particular method of payment. The exercise price of an Option may be paid, to the extent permitted by Applicable Law and as determined by the Board, by one or more of the following methods of payment to the extent set forth in the Option Agreement:

(i) by cash or check, bank draft or money order payable to the Company;

(ii) pursuant to a “cashless exercise” program developed under Regulation T as promulgated by the United States Federal Reserve Board that, prior to the issuance of the Common Stock subject to the

A-3

TABLE OF CONTENTS

Option, results in either the receipt of cash (or check) by the Company or the receipt of irrevocable instructions to pay the exercise price to the Company from the sales proceeds;

(iii) by delivery to the Company (either by actual delivery or attestation) of shares of Common Stock that are already owned by the Participant free and clear of any liens, claims, encumbrances or security interests, with a Fair Market Value on the date of exercise that does not exceed the exercise price, provided that (1) at the time of exercise the Common Stock is publicly traded, (2) any remaining balance of the exercise price not satisfied by such delivery is paid by the Participant in cash or other permitted form of payment, (3) such delivery would not violate any Applicable Law or agreement restricting the redemption of the Common Stock, (4) any certificated shares are endorsed or accompanied by an executed assignment separate from certificate, and (5) such shares have been held by the Participant for any minimum period necessary to avoid adverse accounting treatment as a result of such delivery;

(iv) if the Option is a Nonstatutory Stock Option, by a “net exercise” arrangement pursuant to which the Company will reduce the number of shares of Common Stock issuable upon exercise by the largest whole number of shares with a Fair Market Value on the date of exercise that does not exceed the exercise price, provided that (1) such shares used to pay the exercise price will not be exercisable thereafter and (2) any remaining balance of the exercise price not satisfied by such net exercise is paid by the Participant in cash or other permitted form of payment; or

(v) in any other form of consideration that may be acceptable to the Board and permissible under Applicable Law.

(d) Exercise Procedure and Payment of Appreciation Distribution for SARs. In order to exercise any SAR, the Participant must provide notice of exercise to the Plan Administrator in accordance with the SAR Agreement. The appreciation distribution payable to a Participant upon the exercise of a SAR will not be greater than an amount equal to the excess of (i) the aggregate Fair Market Value on the date of exercise of a number of shares of Common Stock equal to the number of Common Stock equivalents that are vested and being exercised under such SAR, over (ii) the strike price of such SAR. Such appreciation distribution may be paid to the Participant in the form of Common Stock or cash (or any combination of Common Stock and cash) or in any other form of payment, as determined by the Board and specified in the SAR Agreement.

(e) Transferability. Options and SARs may not be transferred to third party financial institutions for value. The Board may impose such additional limitations on the transferability of an Option or SAR as it determines. In the absence of any such determination by the Board, the following restrictions on the transferability of Options and SARs will apply, provided that except as explicitly provided herein, neither an Option nor a SAR may be transferred for consideration and provided, further, that if an Option is an Incentive Stock Option, such Option may be deemed to be a Nonstatutory Stock Option as a result of being transferred:

(i) Restrictions on Transfer. An Option or SAR will not be transferable, except by will or by the laws of descent and distribution, and will be exercisable during the lifetime of the Participant only by the Participant; provided, however, that the Board may permit transfer of an Option or SAR in a manner that is not prohibited by applicable tax and securities laws upon the Participant’s request, including to a trust if the Participant is considered to be the sole beneficial owner of such trust (as determined under Section 671 of the Code and applicable U.S. state law) while such Option or SAR is held in such trust, provided that the Participant and the trustee enter into a transfer and other agreements required by the Company.

(ii) Domestic Relations Orders. Notwithstanding the foregoing, subject to the execution of transfer documentation in a format acceptable to the Company and subject to the approval of the Board or a duly authorized Officer, an Option or SAR may be transferred pursuant to a domestic relations order.

(f) Vesting. The Board may impose such restrictions on or conditions to the vesting and/or exercisability of an Option or SAR as determined by the Board. Except as otherwise provided in the applicable Award Agreement or other written agreement between a Participant and the Company or an Affiliate, vesting of Options and SARs will cease upon termination of the Participant’s Continuous Service.

TABLE OF CONTENTS

(g) Termination of Continuous Service for Cause. Except as explicitly otherwise provided in the Award Agreement or other written agreement between a Participant and the Company or an Affiliate, if a Participant’s Continuous Service is terminated for Cause, the Participant’s Options and SARs will terminate and be forfeited immediately upon such termination of Continuous Service, and the Participant will be prohibited from exercising any portion (including any vested portion) of such Awards on and after the date of such termination of Continuous Service and the Participant will have no further right, title or interest in such forfeited Award, the shares of Common Stock subject to the forfeited Award, or any consideration in respect of the forfeited Award.

(h) Post-Termination Exercise Period Following Termination of Continuous Service for Reasons Other than Cause. Subject to Section 4(i), if a Participant’s Continuous Service terminates for any reason other than for Cause, the Participant may exercise his or her Option or SAR to the extent vested, but only within the following period of time or, if applicable, such other period of time provided in the Award Agreement or other written agreement between a Participant and the Company or an Affiliate; provided, however, that in no event may such Award be exercised after the expiration of its maximum term (as set forth in Section 4(a)):

(i) three months following the date of such termination if such termination is a termination without Cause (other than any termination due to the Participant’s Disability or death);

(ii) 12 months following the date of such termination if such termination is due to the Participant’s Disability;

(iii) 18 months following the date of such termination if such termination is due to the Participant’s death; or

(iv) 18 months following the date of the Participant’s death if such death occurs following the date of such termination but during the period such Award is otherwise exercisable (as provided in (i) or (ii) above).

Following the date of such termination, to the extent the Participant does not exercise such Award within the applicable Post-Termination Exercise Period (or, if earlier, prior to the expiration of the maximum term of such Award), such unexercised portion of the Award will terminate, and the Participant will have no further right, title or interest in terminated Award, the shares of Common Stock subject to the terminated Award, or any consideration in respect of the terminated Award.

(i) Restrictions on Exercise; Extension of Exercisability. A Participant may not exercise an Option or SAR at any time that the issuance of shares of Common Stock upon such exercise would violate Applicable Law. Except as otherwise provided in the Award Agreement or other written agreement between a Participant and the Company or an Affiliate, if a Participant’s Continuous Service terminates for any reason other than for Cause and, at any time during the last thirty days of the applicable Post-Termination Exercise Period, the exercise of the Participant’s Option or SAR would be prohibited solely because the issuance of shares of Common Stock upon such exercise would violate Applicable Law (as determined in the sole discretion of the Board), then the applicable Post-Termination Exercise Period will be extended to the last day of the calendar month that commences following the date the Award would otherwise expire, with an additional extension of the exercise period to the last day of the next calendar month to apply if any of the foregoing restrictions apply at any time during such extended exercise period, generally without limitation as to the maximum permitted number of extensions; provided, however, that in no event may such Award be exercised after the expiration of its maximum term (as set forth in Section 4(a)).

(j) Non-Exempt Employees. No Option or SAR, whether or not vested, granted to an Employee who is a non-exempt employee for purposes of the United States Fair Labor Standards Act of 1938, as amended, will be first exercisable for any shares of Common Stock until at least six months following the date of grant of such Award. Notwithstanding the foregoing, in accordance with the provisions of the United States Worker Economic Opportunity Act, any vested portion of such Award may be exercised earlier than six months following the date of grant of such Award in the event of (i) such Participant’s death or Disability, (ii) a Transaction in which such Award is not assumed, continued or substituted, (iii) a Change in Control, or (iv) such Participant’s retirement (as such term may be defined in the Award Agreement or another applicable agreement or, in the absence of any such definition, in accordance with the Company’s then current

employment policies and guidelines). This Section 4(j) is intended to operate so that any income derived by a non-exempt employee in connection with the exercise or vesting of an Option or SAR will be exempt from his or her regular rate of pay.

(k) Whole Shares. Options and SARs may be exercised only with respect to whole shares of Common Stock or their equivalents.

(a) Restricted Stock Awards and RSU Awards. Each Restricted Stock Award and RSU Award will have such terms and conditions as determined by the Board; provided, however, that each Restricted Stock Award Agreement and RSU Award Agreement will conform (through incorporation of the provisions hereof by reference in the Award Agreement or otherwise) to the substance of each of the following provisions:

(i) Form of Award.

(1) RSAs: To the extent consistent with the Company’s Bylaws, at the Board’s election, shares of Common Stock subject to a Restricted Stock Award may be (i) held in book entry form subject to the Company’s instructions until such shares become vested or any other restrictions lapse, or (ii) evidenced by a certificate, which certificate will be held in such form and manner as determined by the Board. Unless otherwise determined by the Board, a Participant will have voting and other rights as a stockholder of the Company with respect to any shares subject to a Restricted Stock Award.

(2) RSUs: A RSU Award represents a Participant’s right to be issued on a future date the number of shares of Common Stock that is equal to the number of restricted stock units subject to the RSU Award. As a holder of a RSU Award, a Participant is an unsecured creditor of the Company with respect to the Company’s unfunded obligation, if any, to issue shares of Common Stock in settlement of such Award and nothing contained in the Plan or any RSU Agreement, and no action taken pursuant to its provisions, will create or be construed to create a trust of any kind or a fiduciary relationship between a Participant and the Company or an Affiliate or any other person. A Participant will not have voting or any other rights as a stockholder of the Company with respect to any RSU Award (unless and until shares are actually issued in settlement of a vested RSU Award).

(ii) Consideration.

(1) RSA: A Restricted Stock Award may be granted in consideration for (A) cash or check, bank draft or money order payable to the Company, (B) past services to the Company or an Affiliate, or (C) any other form of consideration as the Board may determine and permissible under Applicable Law.

(2) RSU: Unless otherwise determined by the Board at the time of grant, a RSU Award will be granted in consideration for the Participant’s services to the Company or an Affiliate, such that the Participant will not be required to make any payment to the Company (other than such services) with respect to the grant or vesting of the RSU Award, or the issuance of any shares of Common Stock pursuant to the RSU Award. If, at the time of grant, the Board determines that any consideration must be paid by the Participant (in a form other than the Participant’s services to the Company or an Affiliate) upon the issuance of any shares of Common Stock in settlement of the RSU Award, such consideration may be paid in any form of consideration as the Board may determine and permissible under Applicable Law.

(iii) Vesting. The Board may impose such restrictions on or conditions to the vesting of a Restricted Stock Award or RSU Award as determined by the Board. Except as otherwise provided in the Award Agreement or other written agreement between a Participant and the Company or an Affiliate, vesting of Restricted Stock Awards and RSU Awards will cease upon termination of the Participant’s Continuous Service.

(iv) Termination of Continuous Service. Except as otherwise provided in the Award Agreement or other written agreement between a Participant and the Company or an Affiliate, if a Participant’s Continuous Service terminates for any reason, (i) the Company may receive through a forfeiture condition

A-6

TABLE OF CONTENTS

or a repurchase right any or all of the shares of Common Stock held by the Participant under his or her Restricted Stock Award that have not vested as of the date of such termination as set forth in the Restricted Stock Award Agreement and (ii) any portion of his or her RSU Award that has not vested will be forfeited upon such termination and the Participant will have no further right, title or interest in the RSU Award, the shares of Common Stock issuable pursuant to the RSU Award, or any consideration in respect of the RSU Award.

(v) Settlement of RSU Awards. A RSU Award may be settled by the issuance of shares of Common Stock or cash (or any combination thereof) or in any other form of payment, as determined by the Board and specified in the RSU Award Agreement. At the time of grant, the Board may determine to impose such restrictions or conditions that delay such delivery to a date following the vesting of the RSU Award.

(b) Performance Awards. With respect to any Performance Award, the length of any Performance Period, the Performance Goals to be achieved during the Performance Period, the other terms and conditions of such Award, and the measure of whether and to what degree such Performance Goals have been attained will be determined by the Board.

(c) Other Awards. Other Awards may be granted either alone or in addition to Awards provided for under Section 4 and the preceding provisions of this Section 5. Subject to the provisions of the Plan, the Board will have sole and complete discretion to determine the persons to whom and the time or times at which such Other Awards will be granted, the number of shares of Common Stock (or the cash equivalent thereof) to be granted pursuant to such Other Awards and all other terms and conditions of such Other Awards.

(a) Capitalization Adjustments. In the event of a Capitalization Adjustment, the Board shall appropriately and proportionately adjust: (i) the class(es) and maximum number of shares of Common Stock subject to the Plan and the maximum number of shares by which the Share Reserve may annually increase pursuant to Section 2(a), (ii) the class(es) and maximum number of shares that may be issued pursuant to the exercise of Incentive Stock Options pursuant to Section 2(b), and (iii) the class(es) and number of securities and exercise price, strike price or purchase price of Common Stock subject to outstanding Awards. The Board shall make such adjustments, and its determination shall be final, binding and conclusive. Notwithstanding the foregoing, no fractional shares or rights for fractional shares of Common Stock shall be created in order to implement any Capitalization Adjustment. The Board shall determine an appropriate equivalent benefit, if any, for any fractional shares or rights to fractional shares that might be created by the adjustments referred to in the preceding provisions of this Section.

(b) Dissolution or Liquidation. Except as otherwise provided in the Award Agreement, in the event of a dissolution or liquidation of the Company, all outstanding Awards (other than Awards consisting of vested and outstanding shares of Common Stock not subject to a forfeiture condition or the Company’s right of repurchase) will terminate immediately prior to the completion of such dissolution or liquidation, and the shares of Common Stock subject to the Company’s repurchase rights or subject to a forfeiture condition may be repurchased or reacquired by the Company notwithstanding the fact that the holder of such Award is providing Continuous Service, provided, however, that the Board may determine to cause some or all Awards to become fully vested, exercisable and/or no longer subject to repurchase or forfeiture (to the extent such Awards have not previously expired or terminated) before the dissolution or liquidation is completed but contingent on its completion.

(c) Transactions. The following provisions will apply to Awards in the event of a Transaction except as set forth in Section 11, and unless otherwise provided in the instrument evidencing the Award or any other written agreement between the Company or any Affiliate and the Participant or in a director compensation policy or unless otherwise expressly provided by the Board at the time of grant of an Award.

(i) Awards May Be Assumed. In the event of a Transaction, any surviving corporation or acquiring corporation (or the surviving or acquiring corporation’s parent company) may assume or continue any or all Awards outstanding under the Plan or may substitute similar awards for Awards outstanding under the Plan (including but not limited to, awards to acquire the same consideration paid to the stockholders of the Company pursuant to the Transaction), and any reacquisition or repurchase

A-7

TABLE OF CONTENTS

rights held by the Company in respect of Common Stock issued pursuant to Awards may be assigned by the Company to the successor of the Company (or the successor’s parent company, if any), in connection with such Transaction. A surviving corporation or acquiring corporation (or its parent) may choose to assume or continue only a portion of an Award or substitute a similar award for only a portion of an Award, or may choose to assume, continue, or substitute the Awards held by some, but not all Participants. The terms of any assumption, continuation or substitution will be set by the Board.

(ii) Awards Held by Current Participants. In the event of a Transaction in which the surviving corporation or acquiring corporation (or its parent company) does not assume or continue such outstanding Awards or substitute similar awards for such outstanding Awards, then with respect to Awards that have not been assumed, continued or substituted and that are held by Participants whose Continuous Service has not terminated prior to the effective time of the Transaction (referred to as the “ Current Participants ”), the vesting of such Awards (and, with respect to Options and SARs, the time when such Awards may be exercised) will be accelerated in full to a date prior to the effective time of such Transaction (contingent upon the effectiveness of the Transaction) as the Board determines (or, if the Board does not determine such a date, to the date that is five days prior to the effective time of the Transaction), and such Awards will terminate if not exercised (if applicable) at or prior to the effective time of the Transaction, and any reacquisition or repurchase rights held by the Company with respect to such Awards will lapse (contingent upon the effectiveness of the Transaction). With respect to the vesting of Performance Awards that will accelerate upon the occurrence of a Transaction pursuant to this subsection (ii) and that have multiple vesting levels depending on the level of performance, unless otherwise provided in the Award Agreement, the vesting of such Performance Awards will accelerate at 100% of the target level upon the occurrence of the Transaction. With respect to the vesting of Awards that will accelerate upon the occurrence of a Transaction pursuant to this subsection (ii) and are settled in the form of a cash payment, such cash payment will be made no later than 30 days following the occurrence of the Transaction.

(iii) Awards Held by Persons other than Current Participants. In the event of a Transaction in which the surviving corporation or acquiring corporation (or its parent company) does not assume or continue such outstanding Awards or substitute similar awards for such outstanding Awards, then with respect to Awards that have not been assumed, continued or substituted and that are held by persons other than Current Participants, such Awards will terminate if not exercised (if applicable) prior to the occurrence of the Transaction; provided, however, that any reacquisition or repurchase rights held by the Company with respect to such Awards will not terminate and may continue to be exercised notwithstanding the Transaction.

(iv) Payment for Awards in Lieu of Exercise. Notwithstanding the foregoing, in the event an Award will terminate if not exercised prior to the effective time of a Transaction, the Board may provide, in its sole discretion, that the holder of such Award may not exercise such Award but will receive a payment, in such form as may be determined by the Board, equal in value, at the effective time, to the excess, if any, of (1) the value of the property the Participant would have received upon the exercise of the Award (including, at the discretion of the Board, any unvested portion of such Award), over (2) any exercise price payable by such holder in connection with such exercise.

(d) Appointment of Stockholder Representative. As a condition to the receipt of an Award under this Plan, a Participant will be deemed to have agreed that the Award will be subject to the terms of any agreement governing a Transaction involving the Company, including, without limitation, a provision for the appointment of a stockholder representative that is authorized to act on the Participant’s behalf with respect to any escrow, indemnities and any contingent consideration.

(e) No Restriction on Right to Undertake Transactions. The grant of any Award under the Plan and the issuance of shares pursuant to any Award does not affect or restrict in any way the right or power of the Company or the stockholders of the Company to make or authorize any adjustment, recapitalization, reorganization or other change in the Company’s capital structure or its business, any merger or consolidation of the Company, any issue of stock or of options, rights or options to purchase stock or of bonds, debentures, preferred or prior preference stocks whose rights are superior to or affect the Common Stock or the rights thereof or which are convertible into or exchangeable for Common Stock, or the dissolution or liquidation of

the Company, or any sale or transfer of all or any part of its assets or business, or any other corporate act or proceeding, whether of a similar character or otherwise.

A dministration .

(a) Administration by Board. The Board will administer the Plan unless and until the Board delegates administration of the Plan to a Committee or Committees, as provided in subsection (c) below.

(b) Powers of Board. The Board will have the power, subject to, and within the limitations of, the express provisions of the Plan:

(i) To determine from time to time: (1) which of the persons eligible under the Plan will be granted Awards; (2) when and how each Award will be granted; (3) what type or combination of types of Award will be granted; (4) the provisions of each Award granted (which need not be identical), including the time or times when a person will be permitted to receive an issuance of Common Stock or other payment pursuant to an Award; (5) the number of shares of Common Stock or cash equivalent with respect to which an Award will be granted to each such person; (6) the Fair Market Value applicable to an Award; and (7) the terms of any Performance Award that is not valued in whole or in part by reference to, or otherwise based on, the Common Stock, including the amount of cash payment or other property that may be earned and the timing of payment.

(ii) To construe and interpret the Plan and Awards granted under it, and to establish, amend and revoke rules and regulations for its administration. The Board, in the exercise of this power, may correct any defect, omission or inconsistency in the Plan or in any Award Agreement, in a manner and to the extent it deems necessary or expedient to make the Plan or Award fully effective.

(iii) To settle all controversies regarding the Plan and Awards granted under it.

(iv) To accelerate the time at which an Award may first be exercised or the time during which an Award or any part thereof will vest, notwithstanding the provisions in the Award Agreement stating the time at which it may first be exercised or the time during which it will vest.

(v) To prohibit the exercise of any Option, SAR or other exercisable Award during a period of up to 30 days prior to the consummation of any pending stock dividend, stock split, combination or exchange of shares, merger, consolidation or other distribution (other than normal cash dividends) of Company assets to stockholders, or any other change affecting the shares of Common Stock or the share price of the Common Stock (including, but not limited to, any Transaction), for reasons of administrative convenience.

(vi) To suspend or terminate the Plan at any time. Suspension or termination of the Plan will not Materially Impair rights and obligations under any Award granted while the Plan is in effect except with the written consent of the affected Participant.

(vii) To amend the Plan in any respect the Board deems necessary or advisable; provided, however, that stockholder approval will be required for any amendment to the extent required by Applicable Law. Except as provided above, rights under any Award granted before amendment of the Plan will not be Materially Impaired by any amendment of the Plan unless (1) the Company requests the consent of the affected Participant, and (2) such Participant consents in writing.

(viii) To submit any amendment to the Plan for stockholder approval.

(ix) To approve forms of Award Agreements for use under the Plan and to amend the terms of any one or more Awards, including, but not limited to, amendments to provide terms more favorable to the Participant than previously provided in the Award Agreement, subject to any specified limits in the Plan that are not subject to Board discretion; provided however, that, a Participant’s rights under any Award will not be Materially Impaired by any such amendment unless (1) the Company requests the consent of the affected Participant, and (2) such Participant consents in writing.

(x) Generally, to exercise such powers and to perform such acts as the Board deems necessary or expedient to promote the best interests of the Company and that are not in conflict with the provisions of the Plan or Awards.

TABLE OF CONTENTS

(xi) To adopt such procedures and sub-plans as are necessary or appropriate to permit and facilitate participation in the Plan by, or take advantage of specific tax treatment for Awards granted to, Employees, Directors or Consultants who are non-U.S. nationals or employed outside the United States (provided that Board approval will not be necessary for immaterial modifications to the Plan or any Award Agreement to ensure or facilitate compliance with the laws of the relevant non-U.S. jurisdiction).

(i) General. The Board may delegate some or all of the administration of the Plan to a Committee or Committees. If administration of the Plan is delegated to a Committee, the Committee will have, in connection with the administration of the Plan, the powers theretofore possessed by the Board that have been delegated to the Committee, including the power to delegate to another Committee or a subcommittee of the Committee any of the administrative powers the Committee is authorized to exercise (and references in this Plan to the Board will thereafter be to the Committee or subcommittee), subject, however, to such resolutions, not inconsistent with the provisions of the Plan, as may be adopted from time to time by the Board. Each Committee may retain the authority to concurrently administer the Plan with the Committee or subcommittee to which it has delegated its authority hereunder and may, at any time, revest in such Committee some or all of the powers previously delegated. The Board may retain the authority to concurrently administer the Plan with any Committee and may, at any time, revest in the Board some or all of the powers previously delegated.

(ii) Rule 16b-3 Compliance. To the extent an Award is intended to qualify for the exemption from Section 16(b) of the Exchange Act that is available under Rule 16b-3 of the Exchange Act, the Award will be granted by the Board or a Committee that consists solely of two or more Non-Employee Directors, as determined under Rule 16b-3(b)(3) of the Exchange Act and thereafter any action establishing or modifying the terms of the Award will be approved by the Board or a Committee meeting such requirements to the extent necessary for such exemption to remain available.

(d) Effect of Board’s Decision. All determinations, interpretations and constructions made by the Board or any Committee in good faith will not be subject to review by any person and will be final, binding and conclusive on all persons.

(e) Delegation to an Officer. The Board or any Committee may delegate to one or more Officers the authority to do one or both of the following (i) designate Employees who are not Officers to be recipients of Options and SARs (and, to the extent permitted by Applicable Law, other types of Awards) and, to the extent permitted by Applicable Law, the terms thereof, and (ii) determine the number of shares of Common Stock to be subject to such Awards granted to such Employees; provided, however, that the resolutions or charter adopted by the Board or any Committee evidencing such delegation will specify the total number of shares of Common Stock that may be subject to the Awards granted by such Officer and that such Officer may not grant an Award to himself or herself. Any such Awards will be granted on the applicable form of Award Agreement most recently approved for use by the Board or the Committee, unless otherwise provided in the resolutions approving the delegation authority. Notwithstanding anything to the contrary herein, neither the Board nor any Committee may delegate to an Officer who is acting solely in the capacity of an Officer (and not also as a Director) the authority to determine the Fair Market Value.

(f) No Repricing Without Stockholder Approval. Neither the Board nor any Committee shall have the authority to: (1) reduce the exercise price (or strike price) of any outstanding Option or SAR; (2) cancel any outstanding Option or SAR and grant in substitution therefor (A) a new Option, SAR, Restricted Stock Award, RSU Award or Other Award, under the Plan or another equity plan of the Company, covering the same or a different number of shares of Common Stock, (B) cash and/or (C) other valuable consideration (as determined by the Board or any Committee); or (3) take any other action that is treated as a repricing under generally accepted accounting principles, unless the stockholders of the Company have approved such an action within the prior twelve (12) months.

(g) Minimum Vesting Requirements. Notwithstanding any other provision of the Plan, no Award may vest (and/or, if applicable, be exercisable) until at least twelve (12) months following the date of grant of the Award; provided, however, that up to five percent (5%) of the Share Reserve may be subject to Awards that do not meet such vesting (and/or, if applicable, exercisability) requirements.

T ax W ithholding

(a) Withholding Authorization. As a condition to acceptance of any Award under the Plan, a Participant authorizes withholding from payroll and any other amounts payable to such Participant, and otherwise agrees to make adequate provision for, any sums required to satisfy any U.S. and/or non-U.S. federal, state or local tax or social insurance contribution withholding obligations of the Company or an Affiliate, if any, which arise in connection with the grant, vesting, exercise, or settlement of such Award, as applicable. Accordingly, a Participant may not be able to exercise an Award even though the Award is vested, and the Company shall have no obligation to issue shares of Common Stock subject to an Award, unless and until such obligations are satisfied.

(b) Satisfaction of Withholding Obligation. To the extent permitted by the terms of an Award Agreement, the Company may, in its sole discretion, satisfy any U.S. and/or non-U.S. federal, state or local tax or social insurance withholding obligation relating to an Award by any of the following means or by a combination of such means: (i) causing the Participant to tender a cash payment; (ii) withholding shares of Common Stock from the shares of Common Stock issued or otherwise issuable to the Participant in connection with the Award; (iii) withholding cash from an Award settled in cash; (iv) withholding payment from any amounts otherwise payable to the Participant; (v) by allowing a Participant to effectuate a “cashless exercise” pursuant to a program developed under Regulation T as promulgated by the United States Federal Reserve Board; or (vi) by such other method as may be set forth in the Award Agreement.

(c) No Obligation to Notify or Minimize Taxes; No Liability to Claims. Except as required by Applicable Law, the Company has no duty or obligation to any Participant to advise such holder as to the time or manner of exercising such Award. Furthermore, the Company has no duty or obligation to warn or otherwise advise such holder of a pending termination or expiration of an Award or a possible period in which the Award may not be exercised. The Company has no duty or obligation to minimize the tax consequences of an Award to the holder of such Award and will not be liable to any holder of an Award for any adverse tax consequences to such holder in connection with an Award. As a condition to accepting an Award under the Plan, each Participant (i) agrees to not make any claim against the Company, or any of its Officers, Directors, Employees or Affiliates related to tax liabilities arising from such Award or other Company compensation and (ii) acknowledges that such Participant was advised to consult with his or her own personal tax, financial and other legal advisors regarding the tax consequences of the Award and has either done so or knowingly and voluntarily declined to do so. Additionally, each Participant acknowledges any Option or SAR granted under the Plan is exempt from Section 409A only if the exercise or strike price is at least equal to the “fair market value” of the Common Stock on the date of grant as determined by the United States Internal Revenue Service and there is no other impermissible deferral of compensation associated with the Award. Additionally, as a condition to accepting an Option or SAR granted under the Plan, each Participant agrees not to make any claim against the Company, or any of its Officers, Directors, Employees or Affiliates in the event that the United States Internal Revenue Service asserts that such exercise price or strike price is less than the “fair market value” of the Common Stock on the date of grant as subsequently determined by the United States Internal Revenue Service.

(d) Withholding Indemnification. As a condition to accepting an Award under the Plan, in the event that the amount of the Company’s and/or its Affiliate’s withholding obligation in connection with such Award was greater than the amount actually withheld by the Company and/or its Affiliates, each Participant agrees to indemnify and hold the Company and/or its Affiliates harmless from any failure by the Company and/or its Affiliates to withhold the proper amount.

M iscellaneous .

(a) Dividends and Dividend Equivalents.

(i) Dividends or dividend equivalents may not be paid or credited to Options or SARs.

(ii) With respect to any Award other than an Option or SAR, dividends or dividend equivalents may be paid or credited, as applicable, with respect to any shares of Common Stock subject to such Award, as determined by the Board and specified in the applicable Award Agreement; provided, however, that (i) no dividends or dividend equivalents may be paid or settled with respect to any such shares before

A-11

TABLE OF CONTENTS

the date such shares have vested under the terms of such Award Agreement; (ii) any dividends or dividend equivalents that are credited with respect to any such shares shall be subject to all of the terms and conditions applicable to such shares under the terms of such Award Agreement (including, but not limited to, any vesting conditions); and (iii) any dividends or dividend equivalents that are credited with respect to any such shares shall be forfeited to the Company on the date, if any, such shares are forfeited to or repurchased by the Company due to a failure to meet any vesting conditions under the terms of such Award Agreement.

(b) Source of Shares. The stock issuable under the Plan will be shares of authorized but unissued or reacquired Common Stock, including shares repurchased by the Company on the open market or otherwise.

(c) Use of Proceeds from Sales of Common Stock. Proceeds from the sale of shares of Common Stock pursuant to Awards will constitute general funds of the Company.

(d) Corporate Action Constituting Grant of Awards. Corporate action constituting a grant by the Company of an Award to any Participant will be deemed completed as of the date of such corporate action, unless otherwise determined by the Board, regardless of when the instrument, certificate, or letter evidencing the Award is communicated to, or actually received or accepted by, the Participant. In the event that the corporate records (e.g., Board consents, resolutions or minutes) documenting the corporate action approving the grant contain terms (e.g., exercise price, vesting schedule or number of shares) that are inconsistent with those in the Award Agreement or related grant documents as a result of a clerical error in the Award Agreement or related grant documents, the corporate records will control and the Participant will have no legally binding right to the incorrect term in the Award Agreement or related grant documents.

(e) Stockholder Rights. No Participant will be deemed to be the holder of, or to have any of the rights of a holder with respect to, any shares of Common Stock subject to such Award unless and until (i) such Participant has satisfied all requirements for exercise of the Award pursuant to its terms, if applicable, and (ii) the issuance of the Common Stock subject to such Award is reflected in the records of the Company.

(f) No Employment or Other Service Rights. Nothing in the Plan, any Award Agreement or any other instrument executed thereunder or in connection with any Award granted pursuant thereto will confer upon any Participant any right to continue to serve the Company or an Affiliate in the capacity in effect at the time the Award was granted or affect the right of the Company or an Affiliate to terminate at will and without regard to any future vesting opportunity that a Participant may have with respect to any Award (i) the employment of an Employee with or without notice and with or without cause, (ii) the service of a Consultant pursuant to the terms of such Consultant’s agreement with the Company or an Affiliate, or (iii) the service of a Director pursuant to the Bylaws of the Company or an Affiliate, and any applicable provisions of the corporate law of the U.S. state or non-U.S. jurisdiction in which the Company or the Affiliate is incorporated, as the case may be. Further, nothing in the Plan, any Award Agreement or any other instrument executed thereunder or in connection with any Award will constitute any promise or commitment by the Company or an Affiliate regarding the fact or nature of future positions, future work assignments, future compensation or any other term or condition of employment or service or confer any right or benefit under the Award or the Plan unless such right or benefit has specifically accrued under the terms of the Award Agreement and/or Plan.

(g) Change in Time Commitment. In the event a Participant’s regular level of time commitment in the performance of his or her services for the Company and any Affiliates is reduced (for example, and without limitation, if the Participant is an Employee of the Company and the Employee has a change in status from a full-time Employee to a part-time Employee or takes an extended leave of absence) after the date of grant of any Award to the Participant, the Board may determine, to the extent permitted by Applicable Law, to (i) make a corresponding reduction in the number of shares or cash amount subject to any portion of such Award that is scheduled to vest or become payable after the date of such change in time commitment, and (ii) in lieu of or in combination with such a reduction, extend the vesting or payment schedule applicable to such Award. In the event of any such reduction, the Participant will have no right with respect to any portion of the Award that is so reduced or extended.

(h) Execution of Additional Documents. As a condition to accepting an Award under the Plan, the Participant agrees to execute any additional documents or instruments necessary or desirable, as determined

A-12

TABLE OF CONTENTS

in the Plan Administrator’s sole discretion, to carry out the purposes or intent of the Award, or facilitate compliance with securities and/or other regulatory requirements, in each case at the Plan Administrator’s request.

(i) Electronic Delivery and Participation. Any reference herein or in an Award Agreement to a “written” agreement or document will include any agreement or document delivered electronically, filed publicly at www.sec.gov (or any successor website thereto) or posted on the Company’s intranet (or other shared electronic medium controlled by the Company to which the Participant has access). By accepting any Award, the Participant consents to receive documents by electronic delivery and to participate in the Plan through any on-line electronic system established and maintained by the Plan Administrator or another third party selected by the Plan Administrator. The form of delivery of any Common Stock (e.g., a stock certificate or electronic entry evidencing such shares) shall be determined by the Company.

(j) Clawback/Recovery. All Awards granted under the Plan will be subject to recoupment in accordance with any clawback policy that the Company is required to adopt pursuant to the listing standards of any national securities exchange or association on which the Company’s securities are listed or as is otherwise required by the Dodd-Frank Wall Street Reform and Consumer Protection Act or other Applicable Law and any clawback policy that the Company otherwise adopts, to the extent applicable and permissible under Applicable Law. In addition, the Board may impose such other clawback, recovery or recoupment provisions in an Award Agreement as the Board determines necessary or appropriate, including but not limited to a reacquisition right in respect of previously acquired shares of Common Stock or other cash or property upon the occurrence of Cause. No recovery of compensation under such a clawback policy will be an event giving rise to a Participant’s right to voluntarily terminate employment upon a “resignation for good reason,” or for a “constructive termination” or any similar term under any plan of or agreement with the Company.

(k) Securities Law Compliance. A Participant will not be issued any shares in respect of an Award unless either (i) the shares are registered under the Securities Act; or (ii) the Company has determined that such issuance would be exempt from the registration requirements of the Securities Act. Each Award also must comply with other Applicable Law governing the Award, and a Participant will not receive such shares if the Company determines that such receipt would not be in material compliance with Applicable Law.

(l) Transfer or Assignment of Awards; Issued Shares. Except as expressly provided in the Plan or the form of Award Agreement, Awards granted under the Plan may not be transferred or assigned by the Participant. After the vested shares subject to an Award have been issued, or in the case of a Restricted Stock Award and similar awards, after the issued shares have vested, the holder of such shares is free to assign, hypothecate, donate, encumber or otherwise dispose of any interest in such shares provided that any such actions are in compliance with the provisions herein, the terms of the Trading Policy and Applicable Law.

(m) Effect on Other Employee Benefit Plans. The value of any Award granted under the Plan, as determined upon grant, vesting or settlement, shall not be included as compensation, earnings, salaries, or other similar terms used when calculating any Participant’s benefits under any employee benefit plan sponsored by the Company or any Affiliate, except as such plan otherwise expressly provides. The Company expressly reserves its rights to amend, modify, or terminate any of the Company’s or any Affiliate’s employee benefit plans.

(n) Deferrals. To the extent permitted by Applicable Law, the Board, in its sole discretion, may determine that the delivery of Common Stock or the payment of cash, upon the exercise, vesting or settlement of all or a portion of any Award may be deferred and may also establish programs and procedures for deferral elections to be made by Participants. Deferrals will be made in accordance with the requirements of Section 409A.

(o) Section 409A. Unless otherwise expressly provided for in an Award Agreement, the Plan and Award Agreements will be interpreted to the greatest extent possible in a manner that makes the Plan and the Awards granted hereunder exempt from Section 409A, and, to the extent not so exempt, in compliance with the requirements of Section 409A. If the Board determines that any Award granted hereunder is not exempt from and is therefore subject to Section 409A, the Award Agreement evidencing such Award will incorporate the terms and conditions necessary to avoid the consequences specified in Section 409A(a)(1) of the Code, and to the extent an Award Agreement is silent on terms necessary for compliance, such terms are hereby

A-13

TABLE OF CONTENTS

incorporated by reference into the Award Agreement. Notwithstanding anything to the contrary in this Plan (and unless the Award Agreement specifically provides otherwise), if the shares of Common Stock are publicly traded, and if a Participant holding an Award that constitutes “deferred compensation” under Section 409A is a “specified employee” for purposes of Section 409A, no distribution or payment of any amount that is due because of a “separation from service” (as defined in Section 409A without regard to alternative definitions thereunder) will be issued or paid before the date that is six months and one day following the date of such Participant’s “separation from service” or, if earlier, the date of the Participant’s death, unless such distribution or payment can be made in a manner that complies with Section 409A, and any amounts so deferred will be paid in a lump sum on the day after such six month period elapses, with the balance paid thereafter on the original schedule.

(p) Choice of Law. This Plan and any controversy arising out of or relating to this Plan shall be governed by, and construed in accordance with, the internal laws of the State of Delaware, without regard to conflict of law principles that would result in any application of any law other than the law of the State of Delaware.

C ovenants of the C ompany .

(a) Compliance with Law. The Company will seek to obtain from each regulatory commission or agency, as may be deemed necessary, having jurisdiction over the Plan such authority as may be required to grant Awards and to issue and sell shares of Common Stock upon exercise or vesting of the Awards; provided, however, that this undertaking will not require the Company to register under the Securities Act the Plan, any Award or any Common Stock issued or issuable pursuant to any such Award. If, after reasonable efforts and at a reasonable cost, the Company is unable to obtain from any such regulatory commission or agency the authority that counsel for the Company deems necessary or advisable for the lawful issuance and sale of Common Stock under the Plan, the Company will be relieved from any liability for failure to issue and sell Common Stock upon exercise or vesting of such Awards unless and until such authority is obtained. A Participant is not eligible for the grant of an Award or the subsequent issuance of Common Stock pursuant to the Award if such grant or issuance would be in violation of any Applicable Law.

A dditional R ules for A wards S ubject to S ection 409A.

(a) Application. Unless the provisions of this Section of the Plan are expressly superseded by the provisions in the form of Award Agreement, the provisions of this Section shall apply and shall supersede anything to the contrary set forth in the Award Agreement for a Non-Exempt Award.

(b) Non-Exempt Awards Subject to Non-Exempt Severance Arrangements. To the extent a Non-Exempt Award is subject to Section 409A due to application of a Non-Exempt Severance Arrangement, the following provisions of this subsection (b) apply.

(i) If the Non-Exempt Award vests in the ordinary course during the Participant’s Continuous Service in accordance with the vesting schedule set forth in the Award Agreement, and does not accelerate vesting under the terms of a Non-Exempt Severance Arrangement, in no event will the shares be issued in respect of such Non-Exempt Award any later than the later of: (i) December 31 st of the calendar year that includes the applicable vesting date, or (ii) the 60 th day that follows the applicable vesting date.

(ii) If vesting of the Non-Exempt Award accelerates under the terms of a Non-Exempt Severance Arrangement in connection with the Participant’s Separation from Service, and such vesting acceleration provisions were in effect as of the date of grant of the Non-Exempt Award and, therefore, are part of the terms of such Non-Exempt Award as of the date of grant, then the shares will be earlier issued in settlement of such Non-Exempt Award upon the Participant’s Separation from Service in accordance with the terms of the Non-Exempt Severance Arrangement, but in no event later than the 60 th day that follows the date of the Participant’s Separation from Service. However, if at the time the shares would otherwise be issued the Participant is subject to the distribution limitations contained in Section 409A applicable to “specified employees,” as defined in Section 409A(a)(2)(B)(i) of the Code, such shares shall not be issued before the date that is six months following the date of such Participant’s Separation from Service, or, if earlier, the date of the Participant’s death that occurs within such six month period.

A-14

TABLE OF CONTENTS

(iii) If vesting of a Non-Exempt Award accelerates under the terms of a Non-Exempt Severance Arrangement in connection with a Participant’s Separation from Service, and such vesting acceleration provisions were not in effect as of the date of grant of the Non-Exempt Award and, therefore, are not a part of the terms of such Non-Exempt Award on the date of grant, then such acceleration of vesting of the Non-Exempt Award shall not accelerate the issuance date of the shares, but the shares shall instead be issued on the same schedule as set forth in the Grant Notice as if they had vested in the ordinary course during the Participant’s Continuous Service, notwithstanding the vesting acceleration of the Non-Exempt Award. Such issuance schedule is intended to satisfy the requirements of payment on a specified date or pursuant to a fixed schedule, as provided under United States Treasury Regulations Section 1.409A-3(a)(4).

(c) Treatment of Non-Exempt Awards Upon a Transaction for Employees and Consultants. The provisions of this subsection (c) shall apply and shall supersede anything to the contrary set forth in the Plan with respect to the permitted treatment of any Non-Exempt Award in connection with a Transaction if the Participant was either an Employee or Consultant upon the applicable date of grant of the Non-Exempt Award.

(i) Vested Non-Exempt Awards. The following provisions shall apply to any Vested Non-Exempt Award in connection with a Transaction:

(1) If the Transaction is also a Section 409A Change in Control, then the Acquiring Entity may not assume, continue or substitute the Vested Non-Exempt Award. Upon the Section 409A Change in Control, the settlement of the Vested Non-Exempt Award will automatically be accelerated and the shares will be immediately issued in respect of the Vested Non-Exempt Award. Alternatively, the Company may instead provide that the Participant will receive a cash settlement equal to the Fair Market Value of the shares that would otherwise be issued to the Participant upon the Section 409A Change in Control.

(2) If the Transaction is not also a Section 409A Change in Control, then the Acquiring Entity must either assume, continue or substitute each Vested Non-Exempt Award. The shares to be issued in respect of the Vested Non-Exempt Award shall be issued to the Participant by the Acquiring Entity on the same schedule that the shares would have been issued to the Participant if the Transaction had not occurred. In the Acquiring Entity’s discretion, in lieu of an issuance of shares, the Acquiring Entity may instead substitute a cash payment on each applicable issuance date, equal to the Fair Market Value of the shares that would otherwise be issued to the Participant on such issuance dates, with the determination of the Fair Market Value of the shares made on the date of the Transaction.

(ii) Unvested Non-Exempt Awards. The following provisions shall apply to any Unvested Non-Exempt Award unless otherwise determined by the Board pursuant to subsection (e) of this Section.

(1) In the event of a Transaction, the Acquiring Entity shall assume, continue or substitute any Unvested Non-Exempt Award. Unless otherwise determined by the Board, any Unvested Non-Exempt Award will remain subject to the same vesting and forfeiture restrictions that were applicable to the Award prior to the Transaction. The shares to be issued in respect of any Unvested Non-Exempt Award shall be issued to the Participant by the Acquiring Entity on the same schedule that the shares would have been issued to the Participant if the Transaction had not occurred. In the Acquiring Entity’s discretion, in lieu of an issuance of shares, the Acquiring Entity may instead substitute a cash payment on each applicable issuance date, equal to the Fair Market Value of the shares that would otherwise be issued to the Participant on such issuance dates, with the determination of Fair Market Value of the shares made on the date of the Transaction.

(2) If the Acquiring Entity will not assume, substitute or continue any Unvested Non-Exempt Award in connection with a Transaction, then such Award shall automatically terminate and be forfeited upon the Transaction with no consideration payable to any Participant in respect of such forfeited Unvested Non-Exempt Award. Notwithstanding the foregoing, to the extent permitted and in compliance with the requirements of Section 409A, the Board may in its discretion determine to elect to accelerate the vesting and settlement of the Unvested Non-Exempt Award upon the Transaction, or instead substitute a cash payment equal to the Fair Market Value of such shares that

A-15

TABLE OF CONTENTS

would otherwise be issued to the Participant, as further provided in subsection (e)(ii) below. In the absence of such discretionary election by the Board, any Unvested Non-Exempt Award shall be forfeited without payment of any consideration to the affected Participants if the Acquiring Entity will not assume, substitute or continue the Unvested Non-Exempt Awards in connection with the Transaction.

(3) The foregoing treatment shall apply with respect to all Unvested Non-Exempt Awards upon any Transaction, and regardless of whether or not such Transaction is also a Section 409A Change in Control.

(d) Treatment of Non-Exempt Awards Upon a Transaction for Non-Employee Directors. The following provisions of this subsection (d) shall apply and shall supersede anything to the contrary that may be set forth in the Plan with respect to the permitted treatment of a Non-Exempt Director Award in connection with a Transaction.

(i) If the Transaction is also a Section 409A Change in Control, then the Acquiring Entity may not assume, continue or substitute the Non-Exempt Director Award. Upon the Section 409A Change in Control, the vesting and settlement of any Non-Exempt Director Award will automatically be accelerated and the shares will be immediately issued to the Participant in respect of the Non-Exempt Director Award. Alternatively, the Company may provide that the Participant will instead receive a cash settlement equal to the Fair Market Value of the shares that would otherwise be issued to the Participant upon the Section 409A Change in Control pursuant to the preceding provision.

(ii) If the Transaction is not also a Section 409A Change in Control, then the Acquiring Entity must either assume, continue or substitute the Non-Exempt Director Award. Unless otherwise determined by the Board, the Non-Exempt Director Award will remain subject to the same vesting and forfeiture restrictions that were applicable to the Award prior to the Transaction. The shares to be issued in respect of the Non-Exempt Director Award shall be issued to the Participant by the Acquiring Entity on the same schedule that the shares would have been issued to the Participant if the Transaction had not occurred. In the Acquiring Entity’s discretion, in lieu of an issuance of shares, the Acquiring Entity may instead substitute a cash payment on each applicable issuance date, equal to the Fair Market Value of the shares that would otherwise be issued to the Participant on such issuance dates, with the determination of Fair Market Value made on the date of the Transaction.

(e) If the RSU Award is a Non-Exempt Award, then the provisions in this Section 11(e) shall apply and supersede anything to the contrary that may be set forth in the Plan or the Award Agreement with respect to the permitted treatment of such Non-Exempt Award:

(i) Any exercise by the Board of discretion to accelerate the vesting of a Non-Exempt Award shall not result in any acceleration of the scheduled issuance dates for the shares in respect of the Non-Exempt Award unless earlier issuance of the shares upon the applicable vesting dates would be in compliance with the requirements of Section 409A.

(ii) The Company explicitly reserves the right to earlier settle any Non-Exempt Award to the extent permitted and in compliance with the requirements of Section 409A, including pursuant to any of the exemptions available in United States Treasury Regulations Section 1.409A-3(j)(4)(ix).

(iii) To the extent the terms of any Non-Exempt Award provide that it will be settled upon a Change in Control or Transaction, to the extent it is required for compliance with the requirements of Section 409A, the Change in Control or Transaction event triggering settlement must also constitute a Section 409A Change in Control. To the extent the terms of a Non-Exempt Award provides that it will be settled upon a termination of employment or termination of Continuous Service, to the extent it is required for compliance with the requirements of Section 409A, the termination event triggering settlement must also constitute a Separation From Service. However, if at the time the shares would otherwise be issued to a Participant in connection with a “separation from service” such Participant is subject to the distribution limitations contained in Section 409A applicable to “specified employees,” as defined in Section 409A(a)(2)(B)(i) of the Code, such shares shall not be issued before the date that is six months following the date of the Participant’s Separation From Service, or, if earlier, the date of the Participant’s death that occurs within such six month period.

TABLE OF CONTENTS

(iv) The provisions in this subsection (e) for delivery of the shares in respect of the settlement of a RSU Award that is a Non-Exempt Award are intended to comply with the requirements of Section 409A so that the delivery of the shares to the Participant in respect of such Non-Exempt Award will not trigger the additional tax imposed under Section 409A, and any ambiguities herein will be so interpreted.

Notwithstanding the foregoing, the conversion of any convertible securities of the Company will not be treated as a Capitalization Adjustment.

(j) “ Cause ” has the meaning ascribed to such term in any written agreement between the Participant and the Company or an Affiliate defining such term and, in the absence of such agreement, such term means, with respect to a Participant, the occurrence of any of the following events: (i) such Participant’s actual or attempted commission of, or participation in, a fraud or act of dishonesty against the Company or an Affiliate; (ii) such Participant’s intentional, material violation of any contract or agreement between the Participant and the Company or an Affiliate or of any statutory duty owed to the Company or an Affiliate; (iii) such Participant’s unauthorized use or disclosure of the Company’s or any of its Affiliate’s confidential information or trade secrets; or (iv) such Participant’s gross misconduct.

(k) “ Change in Control ” or “ Change of Control ” means the occurrence, in a single transaction or in a series of related transactions, of any one or more of the following events; provided, however, to the extent necessary to avoid adverse personal income tax consequences to the Participant in connection with an Award, such event or events, as the case may be, also constitute a Section 409A Change in Control:

(i) any Exchange Act Person becomes the Owner, directly or indirectly, of securities of the Company representing more than 50% of the combined voting power of the Company’s then outstanding securities other than by virtue of a merger, consolidation or similar transaction.

Notwithstanding the foregoing or any other provision of this Plan, (A) the term Change in Control shall not include a sale of assets, merger or other transaction effected exclusively for the purpose of changing the domicile of the Company, and (B) the definition of Change in Control (or any analogous term) in an individual written agreement between the Company or any Affiliate and the Participant shall supersede the foregoing definition with respect to Awards subject to such agreement; provided, however, that if no definition of Change in Control or any analogous term is set forth in such an individual written agreement, the foregoing definition shall apply.

(l) “ Code ” means the Internal Revenue Code of 1986, as amended, including any applicable regulations and guidance thereunder.

However, service solely as a Director, or payment of a fee for such service, will not cause a Director to be considered a “Consultant” for purposes of the Plan. Notwithstanding the foregoing, a person is treated as a Consultant under this Plan only if a Form S-8 Registration Statement under the Securities Act is available to register either the offer or the sale of the Company’s securities to such person.

(r) “ Continuous Service ” means that the Participant’s service with the Company or an Affiliate, whether as an Employee, Director or Consultant, is not interrupted or terminated. A change in the capacity in which the Participant renders service to the Company or an Affiliate as an Employee, Director or Consultant or a change in the Entity for which the Participant renders such service, provided that there is no interruption or termination of the Participant’s service with the Company or an Affiliate, will not terminate a Participant’s Continuous Service; provided, however, that if the Entity for which a Participant is rendering services ceases to qualify as an Affiliate, as determined by the Board, such Participant’s Continuous Service will be considered to have terminated on the date such Entity ceases to qualify as an Affiliate. For example, a change in status from an Employee of the Company to a Consultant of an Affiliate or to a Director will not constitute an interruption of Continuous Service. To the extent permitted by law, the Board or the chief executive officer of the Company, in that party’s sole discretion, may determine whether Continuous Service will be considered interrupted in the case of (i) any leave of absence approved by the Board or chief executive officer, including sick leave, military leave or any other personal leave, or (ii) transfers between the Company, an Affiliate, or their successors. Notwithstanding the foregoing, a leave of absence will be treated as Continuous Service for purposes of vesting in an Award only to such extent as may be provided in the Company’s leave of absence policy, in the written terms of any leave of absence agreement or policy applicable to the Participant, or as

A-19

TABLE OF CONTENTS

otherwise required by law. In addition, to the extent required for exemption from or compliance with Section 409A, the determination of whether there has been a termination of Continuous Service will be made, and such term will be construed, in a manner that is consistent with the definition of “separation from service” as defined under United States Treasury Regulation Section 1.409A-1(h) (without regard to any alternative definition thereunder).

(s) “ Corporate Transaction ” means the consummation, in a single transaction or in a series of related transactions, of any one or more of the following events:

(ii) a sale or other disposition of at least 50% of the outstanding securities of the Company;

(iii) a merger, consolidation or similar transaction following which the Company is not the surviving corporation; or

(iv) a merger, consolidation or similar transaction following which the Company is the surviving corporation but the shares of Common Stock outstanding immediately preceding the merger, consolidation or similar transaction are converted or exchanged by virtue of the merger, consolidation or similar transaction into other property, whether in the form of securities, cash or otherwise.
