**ATRICURE, INC.**

**PROXY STATEMENT**

**FOR**

**2026 ANNUAL MEETING OF STOCKHOLDERS**

The Board of Directors of AtriCure, Inc., a Delaware corporation, is soliciting the enclosed proxy from you. The proxy will be used at our 2026 Annual Meeting of Stockholders to be held on Monday, May 18, 2026, beginning at 11:00 a.m. EDT. The Annual Meeting will be held online at www.virtualshareholdermeeting.com/ATRC2026. This proxy statement contains important information regarding the 2026 Annual Meeting of Stockholders. Specifically, it identifies the matters upon which you are being asked to vote, provides information that you may find useful in determining how to vote and describes the voting procedures.

In this proxy statement: the terms *"we", "our", "us", "AtriCure"* and the *"Company"* each refer to AtriCure, Inc.; the term *"Board"* means our Board of Directors; the term *"proxy materials"* means this proxy statement, the enclosed proxy card and our Annual Report on Form 10-K for the year ended December 31, 2025, filed with the U.S. Securities and Exchange Commission (SEC); and the term *"meeting"* means our 2026 Annual Meeting of Stockholders, including any continuations, postponements or adjournments thereof.

**QUESTIONS AND ANSWERS REGARDING THIS SOLICITATION**

**AND VOTING AT THE ANNUAL MEETING**

***Why will I be able to attend the meeting virtually and not in person?***

We are hosting a virtual meeting of stockholders because the virtual meeting format provides expanded access and improved communication between our stockholders and the Company. We see the virtual format as a way to drive more stockholders to attend and participate in the Annual Meeting because the virtual format allows stockholders, wherever they may be located, to attend the Annual Meeting. Mindful that our stockholders reside in locations throughout the United States and the world, we want to provide an opportunity to our stockholders to attend the Annual Meeting without incurring the expense or devoting the time to travel to a physical location. In other words, we believe that the virtual format not only enhances the access stockholders have in attending the Annual Meeting, but it also saves our stockholders the money and time travel can require.

We have designed our virtual format to enhance, rather than constrain, stockholders' access and participation. For example, if you experience technical difficulties during the Annual Meeting, there will be technicians ready to assist you with any technical difficulties you may have accessing the virtual meeting or voting at the meeting. If you encounter any difficulties accessing the virtual meeting during the check-in or meeting time, please call the technical support number that will be listed on the Annual Meeting login web page.

***How can I receive proxy materials?***

Under rules adopted by the U.S. Securities and Exchange Commission (SEC), we are furnishing proxy materials to our stockholders primarily via the Internet, instead of mailing printed copies of proxy materials to each stockholder. On or about April 6, 2026, we began mailing to our stockholders a Notice of Internet Availability of Proxy Materials (Notice) containing instructions on how to access this proxy statement, the accompanying notice of annual meeting and our annual report for the fiscal year ended December 31, 2025 online. If you received the Notice, you will not automatically receive a printed copy of proxy materials. Instead, the Notice instructs you on how to access and review all of the important information contained in the proxy materials. The Notice also instructs you on how you may submit your proxy via the Internet.

You can receive a printed copy of our proxy materials by following the instructions contained in the Notice regarding how you may request to receive your materials electronically or in printed form. Requests for printed copies of the proxy materials can be made by Internet at http://www.proxyvote.com, by telephone at 1-800-579-1639 or by email at sendmaterial@proxyvote.com by sending a blank email with your control number in the subject line.

**<u>[**Table of Contents**](#ic2d59f9bf5e7474b9ef29aaf75ccdc2b_7)</u>**

***What information is contained in this proxy statement?***

The information in this proxy statement relates to the proposals to be voted on at the meeting, the voting process, the compensation of our directors and the most highly paid executive officers during 2025 and certain other required information.

***Who is entitled to vote at the meeting?***

Only stockholders who owned our common stock at the close of business on March 26, 2026 (the Record Date) are entitled to notice of and to vote at the meeting and at any continuations, postponements or adjournments thereof.

***Who can attend the meeting?***

Stockholders of records as of the Record Date may attend the meeting. If you are not a stockholder of record but hold shares in street name (that is, through a broker or nominee), you will need to provide proof of beneficial ownership as of the Record Date, such as your most recent brokerage account statement, a copy of the voting instruction card provided by your broker, trustee or nominee, or other similar evidence of ownership in order to attend the meeting.

***What are my voting rights?***

On each matter to be voted upon, you have one vote for each share of common stock you own as of March 26, 2026. You may vote all shares owned by you as of March 26, 2026, including (1) shares held directly in your name as the *stockholder of record* and (2) shares held for you as the *beneficial owner* through a broker, trustee or other nominee such as a bank.

These proposals are described more fully below. As of the date of this proxy statement, this is the only business that our Board intends to present or knows of that others will present at the meeting. If any other matter or matters are properly brought before the meeting, each properly executed proxy card will be voted in the discretion of the proxies named therein.

***What constitutes a quorum?***

A quorum is required to conduct business at the meeting. The presence at the meeting, virtually or by proxy, of the holders of a majority of the shares of our common stock entitled to vote at the meeting will constitute a quorum. As of March 26, 2026, 50,634,808 shares of our common stock were outstanding. Both abstentions and broker non-votes are counted for the purpose of determining the presence of a quorum.

***What is the difference between holding shares as a stockholder of record and as a beneficial owner?***

If your shares are registered directly in your name with our transfer agent, Equiniti Trust Company, LLC, you are considered, with respect to those shares, the *stockholder of record*, and these proxy materials are being sent directly to you by us. As the *stockholder of record*, you have the right to grant your voting proxy directly to the persons named as proxy holders or to vote virtually at the meeting. We have enclosed a proxy card for your use.

If your shares are held in a brokerage account or by another nominee, you are considered the *beneficial owner* of shares held in *street name*, and these proxy materials are being forwarded to you together with a voting instruction card. As the beneficial owner, you have the right to direct your broker, trustee or nominee how to vote and are also invited to attend the meeting. Please note that since a beneficial owner is not the *stockholder of record*, you may not vote these shares virtually at the meeting unless you obtain a "legal proxy" from the broker, trustee or nominee that holds your shares, which

------

**<u>[**Table of Contents**](#ic2d59f9bf5e7474b9ef29aaf75ccdc2b_7)</u>**

gives you the right to vote the shares at the meeting. Your broker, trustee or nominee has enclosed or provided voting instructions for your use in directing the broker, trustee or nominee as to how you would like them to vote your shares.

***How can I vote my shares virtually at the meeting?***

If you are a registered stockholder, there are several ways for you to vote. You may attend the Annual Meeting via the Internet and vote during the Annual Meeting. You may also vote by Internet before the date of the Annual Meeting, by proxy or by telephone, using one of the methods described in the proxy card. Even if you plan to attend the meeting, we recommend that you also submit your proxy card or voting instructions as described below so that your vote will be counted if you later decide not to, or are unable to, attend the meeting.

***Can I vote my shares without attending the meeting?***

Whether you hold shares directly as the stockholder of record or beneficially in street name, you may direct how your shares are voted without attending the meeting. Stockholders of record may submit proxies by the Internet or telephone by following the instructions in the Notice or by completing, signing and dating their proxy cards and mailing them in the accompanying pre-addressed envelope. Beneficial owners may vote by following the instructions provided by the broker, trustee or nominee holding the shares.

***What if I want to revoke and change my vote?***

You may change your vote at any time prior to the vote at the meeting. If you are the stockholder of record, you may change your vote: (i) by granting a new proxy bearing a later date or granting a later proxy by telephone or the Internet (which automatically revokes your earlier proxy), (ii) by providing a written notice of revocation to our Secretary prior to your shares being voted or (iii) by attending the meeting and voting virtually. Please note that attending the meeting will not cause your previously granted proxy to be revoked unless you specifically so request. For shares you hold beneficially in street name, you may change your vote by submitting new voting instructions to your broker, trustee or nominee, or, if you have obtained a legal proxy from your broker, trustee or nominee which gives you the right to vote your shares, by attending the meeting and voting virtually.

***What vote is required to approve each item and how are votes counted?***

The vote required to approve each item of business and the method for counting votes is set forth below:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Election of Directors.** AtriCure has adopted a majority voting standard for director elections which means that, subject to the provisions of Section 3.3 of our Bylaws, in an uncontested election of directors such as this (i.e., an election where the number of nominees does not exceed the number of directors to be elected at the meeting), each director shall be elected by the vote of the majority of the votes cast with respect to that director's election at any meeting for the election of directors at which a quorum is present. A "majority of the votes cast" means that the number of shares voted "for" a director must exceed the number of votes cast "against" that director's election. "Abstentions" and "broker non-votes" shall not be counted as votes cast with respect to a director's election. You may vote "FOR", "AGAINST" or "ABSTAIN" with respect to any or all of the director nominees. Abstentions and broker non-votes will have no effect on the election of directors.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Ratification of Independent Registered Public Accounting Firm.** For the approval of the ratification of the independent registered public accounting firm, the affirmative "FOR" vote of a majority of the voting power of the shares represented virtually or by proxy and entitled to vote thereon will be required. You may vote "FOR", "AGAINST" or "ABSTAIN" for this item of business. If you "ABSTAIN", your abstention has the same effect as a vote "AGAINST". Broker non-votes will have no effect on the approval of this item of business.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Approval of Amendment to the AtriCure, Inc. 2023 Stock Incentive Plan.** For the amendment of the AtriCure, Inc. 2023 Stock Incentive Plan, the affirmative "FOR" vote of a majority of the voting power of the shares represented virtually or by proxy and entitled to vote thereon will be required. You may vote "FOR", "AGAINST" or "ABSTAIN" for this item of business. If you "ABSTAIN", your abstention has the same effect as a vote "AGAINST". Broker non-votes will have no effect on the approval of this item of business.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Approval of Amendment to the AtriCure, Inc. 2018 Employee Stock Purchase Plan.** For the amendment of the AtriCure, Inc. 2018 Employee Stock Purchase Plan, the affirmative "FOR" vote of a majority of the voting power of the shares represented virtually or by proxy and entitled to vote thereon will be required. You may vote "FOR", "AGAINST" or "ABSTAIN" for this item of business. If you "ABSTAIN", your abstention has the same effect as a vote "AGAINST". Broker non-votes will have no effect on the approval of this item of business.

------

**<u>[**Table of Contents**](#ic2d59f9bf5e7474b9ef29aaf75ccdc2b_7)</u>**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Advisory Vote on Compensation of Named Executive Officers.** For the approval, on an advisory basis, of the compensation of our named executive officers, the affirmative "FOR" vote of a majority of the voting power of the shares represented virtually or by proxy and entitled to vote thereon will be required. You may vote "FOR", "AGAINST" or "ABSTAIN" for this item of business. If you "ABSTAIN", your abstention has the same effect as a vote "AGAINST". Broker non-votes will have no effect on the approval of this item of business.

If you provide specific instructions with regard to certain items, your shares will be voted as you instruct on such items. If you sign your proxy card or voting instruction card without giving specific instructions, your shares will be voted in accordance with the recommendations of the Board ("FOR" all of the nominees to the Board, "FOR" ratification of the independent registered public accounting firm, "FOR" the amendment of the AtriCure, Inc. 2023 Stock Incentive Plan, "FOR" the amendment of the AtriCure, Inc. 2018 Employee Stock Purchase Plan, "FOR" the approval of the compensation of our named executive officers and in the discretion of the proxy holders on any other matters that properly come before the meeting).

***What is a "broker non-vote"?***

Under the rules that govern brokers who own shares that are held in street name for their clients who are the beneficial owners of the shares, brokers have the discretion to vote uninstructed shares on routine matters. The ratification of the appointment of an independent public accounting firm (Proposal 2) is considered a routine matter. Your broker, therefore, may vote your shares in its discretion on this routine matter if you do not instruct your broker how to vote on them. If a matter is not considered routine, then your broker is prohibited from voting your shares on the matter unless you have given voting instructions on that matter to your broker.

**Because Proposal 1 (election of directors), Proposal 3 (amendment to the AtriCure, Inc. 2023 Stock Incentive Plan), Proposal 4 (amendment to the AtriCure, Inc. 2018 Employee Stock Purchase Plan) and Proposal 5 (advisory vote on compensation of named executive officers) are not considered routine, brokers holding shares for their customers will not have the ability to cast votes with respect to Proposals 1, 3, 4 and 5 unless they have received instructions from their customers. It is important, therefore, that you provide instructions to your broker if your shares are held by a broker so that your votes with respect to Proposals 1, 3, 4 and 5 are counted. Your broker, therefore, will need to return a proxy card without voting on Proposals 1, 3, 4 and 5 if you do not give voting instructions with respect to these matters. This is referred to as a "broker non-vote".**

***How are "broker non-votes" counted?***

Broker non-votes will be counted for the purpose of determining the presence of a quorum for the transaction of business and will have the effects described above.

***How are abstentions counted?***

If you return a proxy card that indicates an abstention from voting, the shares represented will be counted for the purpose of determining both the presence of a quorum and the total number of shares represented and entitled to vote with respect to a proposal. Abstentions will have the same effect as a vote "AGAINST" for Proposals 2, 3, 4 and 5, but will have no effect on the election of directors.

***What happens if additional matters are presented at the meeting?***

Other than the five proposals described in this proxy statement, we are not aware of any other business to be acted upon at the meeting. If you grant a proxy, the persons named as proxy holders, Michael H. Carrel (our President and Chief Executive Officer) and Angela L. Wirick (our Chief Financial Officer), will have the discretion to vote your shares on any additional matters properly presented for a vote at the meeting. If, for any unforeseen reason, any of our nominees are not available as a candidate for director, the persons named as proxy holders will vote your proxy for such other candidate or candidates as may be nominated by our Board.

***Who will serve as inspector of election?***

The Secretary of the Company will tabulate the votes and act as inspector of election at the meeting.

***What should I do in the event that I receive more than one set of proxy/voting materials?***

You may receive more than one set of these proxy materials, including multiple copies of this proxy statement and multiple proxy cards or voting instruction cards. For instance, if you hold your shares in more than one brokerage account, you may receive a separate voting instruction card for each brokerage account in which you hold shares. In addition, if you are a stockholder of record and your shares are registered in more than one name, you may receive more than one proxy

**<u>[**Table of Contents**](#ic2d59f9bf5e7474b9ef29aaf75ccdc2b_7)</u>**

card. Please complete, sign, date and return each proxy card and voting instruction card that you receive to ensure that all of your shares are voted.

***Who is soliciting my vote, and who will bear the costs of this solicitation?***

Your vote is being solicited on behalf of the Board, and the Company will bear the entire cost of solicitation of proxies, including preparation, assembly, printing and mailing of this proxy statement. In addition to these proxy materials, our directors and employees may also solicit proxies virtually, by telephone, by e-mail or by other means of communication. Directors and employees will not be paid any additional compensation for soliciting proxies. We may reimburse brokerage firms, banks and other agents for the cost of forwarding proxy materials to beneficial owners.

***Where can I find the voting results of the meeting?***

We intend to announce preliminary voting results at the meeting and publish final results in a Current Report on Form 8-K to be filed with the United States Securities and Exchange Commission within four business days after the meeting.

***What is the deadline to propose actions for consideration at next year's annual meeting of stockholders or to nominate individuals to serve as directors?***

As a stockholder, you may be entitled to present proposals for action at a future meeting of stockholders, including director nominations.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Stockholder Proposals:** For stockholder proposals to be submitted for consideration at the annual meeting to be held in 2027 (2027 Annual Meeting), the written notice that complies with the requirements of our Bylaws must be received by the Secretary of AtriCure at our principal executive offices no earlier than November 9, 2026 and no later than December 7, 2026.

In addition, our Bylaws permit stockholders to nominate directors for election at an annual meeting of stockholders. To nominate a director at an annual meeting, the stockholder must provide the information required by our Bylaws, as well as a statement by the nominee consenting to being named as a nominee and to serve as a director if elected. In addition, the stockholder must give timely notice to our Secretary in accordance with the provisions of our Bylaws, which require that the notice be received by our Secretary no earlier than November 9, 2026 and no later than December 7, 2026. In order to comply with the universal proxy rules, stockholders who intend to solicit proxies for the 2027 Annual Meeting in support of director nominees other than AtriCure's nominees must also provide notice to AtriCure that sets forth the information required by Exchange Act Rule 14a-19 not later than December 7, 2026.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Copy of Bylaw Provisions:** You may contact our Secretary at our principal executive offices for a copy of the relevant Bylaw provisions regarding the requirements for making stockholder proposals and nominating director candidates. Our Bylaws are also filed as an exhibit to our Annual Report on Form 10-K filed with sec.gov.

**Board of Directors' Recommendation**

**THE BOARD RECOMMENDS THAT YOU VOTE FOR EACH OF THE NOMINEES FOR DIRECTOR LISTED ABOVE.**

**<u>[**Table of Contents**](#ic2d59f9bf5e7474b9ef29aaf75ccdc2b_7)</u>**

**CORPORATE GOVERNANCE AND BOARD MATTERS**

**Board Leadership Structure**

The Company has separate Chief Executive Officer and Board Chair positions. Mr. White serves as our Chairman of the Board, presiding over Board meetings and providing the Company with the benefit of his appreciation for and understanding of the risks associated with the Company's business, as well as an intimate knowledge of the Company's technologies and the medical device industry. Mr. Carrel serves as our President and Chief Executive Officer and provides the Company with the benefit of his strategic and creative vision, an extensive knowledge of the Company's operations, an understanding of the day-to-day challenges faced by companies in the medical device industry and his business and financial expertise.

The Board currently believes that, at this time, based on the skills and responsibilities of the various members of the Board and management, and in light of the general economic, business and competitive environment facing the Company, the separation of the Chair and Chief Executive Officer roles enhances appropriate oversight of management by the Board, Board independence, the accountability to our stockholders by the Board and our overall leadership structure. Furthermore, the Board believes that maintaining separation of the Chair function from that of the Chief Executive Officer allows the Chief Executive Officer to properly focus on managing the business, rather than requiring a significant portion of his efforts to be spent on also overseeing Board matters.

**Board Refreshment and Diversity**

The Nominating and Corporate Governance Committee continues to consider the views of institutional investors and proxy advisory firms as it evaluates the composition of the Board. The Nominating and Corporate Governance Committee uses the annual Board and Committee evaluation processes to address Board refreshment and considers diversity a priority. The National Association of Corporate Directors (NACD) recognized us as the winner of the 2022 Diversity, Equity & Inclusion Award in the Small Cap - Public Company category. This award recognizes boards that have improved their governance and created long-term value for stakeholders by implementing forward-thinking diversity, equity and inclusion practices. We believe that the diversity of our Board of Directors helps to set the "tone at the top" for our initiatives.

*Stockholder Nominations and Recommendations.* As described above in the Questions and Answers section under "What is the deadline to propose actions for consideration at next year's meeting of stockholders or to nominate individuals to serve as directors?" our Bylaws set forth the procedure for the proper submission of stockholder nominations for membership on our Board. In addition, the Nominating and Corporate Governance Committee may consider properly submitted stockholder recommendations (as opposed to formal nominations) for candidates for membership on the Board. A stockholder may make such a recommendation by submitting the information required by our Bylaws and the following information to our Secretary at 7555 Innovation Way, Mason, Ohio 45040: the candidate's name, age, home and business contact information, principal occupation or employment, the class and number of shares of AtriCure stock beneficially owned, information regarding any relationships, arrangements or understandings between the candidate and AtriCure and any other information relating to the candidate that is required to be disclosed in the solicitation of proxies for election of directors or is otherwise required, including the candidate's written consent to being named in the proxy statement, if any, as a nominee and to serving as a director if elected.

*Director Qualifications.* Members of our Board should have the highest professional and personal ethics and values and conduct themselves consistent with our Code of Conduct. In accordance with our Corporate Governance Guidelines, the Nominating and Corporate Governance Committee formally reviews each director's continuation on the Board at the expiration of the director's term. The Committee believes that candidates and nominees must reflect a Board that is comprised of directors who (i) are predominantly independent, (ii) are of high integrity, (iii) have qualifications that will increase overall Board effectiveness and (iv) meet other requirements as may be required by applicable rules, such as financial literacy or financial expertise with respect to Audit Committee members and the qualifications set forth in our Bylaws.

*Identifying and Evaluating Director Nominees.* New candidates for nomination may come to the attention of our Board through professional search firms, stockholders, existing directors, our executive officers or other persons. The Nominating and Corporate Governance Committee will carefully review the qualifications of any candidates who have been properly brought to its attention. Such review may, in the Committee's discretion, include a review solely of information provided to the Committee or may also include discussions with persons familiar with the candidate, an interview with the candidate or other actions that the Committee deems proper. The Committee will consider the suitability of each candidate, including the current members of our Board, in light of the current size and composition of the Board. In evaluating the qualifications of the candidates, the Committee considers many factors including issues of character,

------

**<u>[**Table of Contents**](#ic2d59f9bf5e7474b9ef29aaf75ccdc2b_7)</u>**

judgment, independence, age, expertise, diversity of experience, length of service, other commitments and the like. The Committee evaluates such factors, among others, and does not assign any particular weighting or priority to any of these factors nor does the Committee have a formal policy with respect to diversity. Candidates properly recommended by stockholders are evaluated by the independent directors using the same criteria as other candidates.

**Director Skills and Qualifications**

The Board has focused on maintaining a highly skilled and qualified group of directors with a high level of gender diversity. As of the date of this proxy statement, 56% of the Company's Board of Directors were women. The following is a summary of relevant skills and qualifications of our existing directors.

**Independence of the Board**

The NASDAQ Global Market (NASDAQ) listing standards require that a majority of the members of a listed company's board of directors qualify as "independent", as affirmatively determined by the board of directors. Currently, our Board consists of the following nine directors: Michael H. Carrel, Regina E. Groves, B. Kristine Johnson, Shlomo Nachman, Karen N. Prange, Deborah H. Telman, Sven A. Wehrwein, Robert S. White (Chairman) and Maggie Yuen. Our Board has affirmatively determined that each of the directors and nominees, other than Michael H. Carrel, our President and Chief Executive Officer, is independent under the listing standards established by NASDAQ.

As required under the NASDAQ listing standards, our non-management directors meet in regularly scheduled executive sessions at which only independent directors are present.

**Committees of the Board**

Our Board has five standing committees: the Audit Committee; the Compensation Committee; the Compliance, Quality and Risk Committee; the Nominating and Corporate Governance Committee; and the Strategy Committee. Each committee has a written charter which is available on our website at ir.atricure.com under "Corporate Governance". From time to time, our Board may also appoint committees for special purposes.

Our Board of Directors attended the Annual Meeting and met five times during 2025. The following table lists the number of times each committee met in 2025, the major responsibilities, and the current membership for each committee. The table on page [6](#ic2d59f9bf5e7474b9ef29aaf75ccdc2b_16) and the notes thereto describe membership and chair positions effective as of the date of the Annual Meeting.

The composition of the Compensation; Compliance, Quality and Risk; Nominating and Governance; and Strategy Committees satisfies the independence requirements of NASDAQ. Our Board has determined that each member of the Audit Committee meets the independence and financial literacy requirements of the NASDAQ rules and the independence requirements of the SEC. Our Board has also determined that Regina E. Groves, Sven A. Wehrwein, and Maggie Yuen each qualify as an "audit committee financial expert", as defined in SEC rules.

Our directors are strongly encouraged to attend the Company's annual meeting of stockholders. All of our directors which served during 2025 attended the 2025 Annual Meeting. All of our directors attended at least 75% of the aggregate of all Board meetings and meetings of Committees on which such directors served during 2025.

**Director Compensation**

The Compensation Committee engages an independent compensation consultant to conduct a competitive pay assessment with respect to the compensation of the Company's non-employee directors every two to three years. Each non-employee director receives retainers for service as follows:

**Corporate Governance Guidelines**

The Board has adopted Corporate Governance Guidelines to promote the effective functioning of the Board and its Committees, to promote the interests of stockholders and to create a common set of expectations as to how the Board, its Committees, individual directors and management should perform their respective functions. The Board believes that ethics and integrity cannot be legislated or mandated by directive or policy and that the ethics, character, integrity and values of our directors and management remain a critical safeguard in quality corporate governance. The Corporate Governance Guidelines establish the practices the Board will follow with respect to, among other practices, board composition and selection of board nominees, director responsibilities, chief executive officer evaluation, management development and succession planning, director compensation, board committees and annual board and committee performance evaluations. A copy of the Corporate Governance Guidelines is available on our website at ir.atricure.com under "Corporate Governance".

**Code of Conduct**

AtriCure is committed to maintaining the highest standards of business conduct and ethics. Our Code of Conduct reflects our values and the business practices and principles of behavior that support this commitment. Our Code of Conduct is an integral part of our business conduct compliance program and embodies our commitment to conduct operations in accordance with the highest legal and ethical standards. The Code of Conduct applies to all of our officers, directors and employees. Each officer, director and employee receives training when onboarded and annually thereafter and is responsible for acknowledging, understanding and complying with the Code of Conduct. The Code of Conduct is supplemented by an additional Code of Ethics for the Chief Executive Officer and Senior Financial Officers. The Code of Ethics is applicable to our Chief Executive Officer, Chief Financial Officer and key finance employees with responsibility or authority for financial control, oversight or reporting matters. Each code is available on our website at ir.atricure.com under "Corporate Governance". We will post any amendments to either code, as well as any waivers that are required to be disclosed by the rules of the SEC or NASDAQ, on our website.

We have also adopted and implemented voluntary standards established by the Advanced Medical Technology Association (AdvaMed), a United States trade association for medical device manufacturers, governing interactions between medical device manufacturers and healthcare professionals (HCPs) known as the AdvaMed Code of Ethics on Interactions with Health Care Professionals (AdvaMed Code). These standards are intended to ensure that such interactions are transparent and comply with applicable laws, regulations and government guidance. The standards address interactions related to sales and marketing practices, research and development, product training and education, grants and charitable contributions, support of third-party educational conferences and consulting arrangements. AtriCure is also a member of MedTech Europe, a voluntary trade association for the medical technology industry including diagnostics, medical devices

**<u>[**Table of Contents**](#ic2d59f9bf5e7474b9ef29aaf75ccdc2b_7)</u>**

and digital health. MedTech Europe and its members are committed to a high level of ethical business practices and have put in place strict guidelines to advise medical technology manufacturers on how to collaborate ethically with HCPs and healthcare organizations (HCOs). It covers medical education and research and development. It also introduces an independent enforcement mechanism and transparency obligations. The Code sets clear and transparent rules for the industry's relationships with HCPs and HCOs, including company events, third-party organized events, arrangements with consultants, gifts, research and financial support to medical education. We have adopted the MedTech Code and incorporated its principles in our Global Health Care Compliance Manual, employee training programs and relationships with medical professionals. This manual also takes into account other global compliance principles as set forth in other international code of ethics, such as the APAC Med Code of Ethical Conduct and AdvaMed China Code.

**Compensation Committee Interlocks and Insider Participation**

During 2025 and through the date of this proxy statement, none of the members of our Compensation Committee were or are an officer or employee of the Company, had or have any relationship with the Company requiring disclosure under Item 404 of Regulation S-K, and no executive officer of the Company served or serves on the compensation committee or board of any company that employed or employs any member of the Company's Compensation Committee or Board of Directors.

**Certain Relationships and Related Party Transactions**

Our Audit Committee charter provides that the Audit Committee will review and discuss with management potential transactions with related parties. Related party transactions requiring Audit Committee approval include transactions that are significant in size and transactions that involve terms or aspects that differ from those which would be entered into between independent parties.

**Communications with the Board of Directors**

Stockholders are invited to communicate to the Board or its committees by writing to: AtriCure, Inc., Chair of the Board of Directors or the Chair of a Board committee, 7555 Innovation Way, Mason, Ohio 45040. All such stockholder communications (except for spam, junk mail, mass mailings, resumes, job inquiries, surveys, business solicitations or advertisements, or patently offensive, hostile, threatening or otherwise unsuitable or inappropriate material) will be forwarded to the specific director or directors to whom the communications are addressed.

**Board's Role in Risk Oversight**

Management is responsible for the day-to-day management of risks we face, while the Board, as a whole and through its committees, has the responsibility for the oversight of our risk management processes. Our Enterprise Risk Management ("ERM") program provides an ongoing process at all levels across each business unit and corporate function to identify, assess and monitor risk, and to implement mitigating actions, if possible. When the ERM process identifies a material risk, it will be elevated through the management team to the Compliance, Quality and Risk Committee and the Board for its review and consideration. Both the full Board and the Compliance, Quality and Risk Committee periodically receive and review presentations from management regarding the ERM process to assess whether it is functioning effectively.

Senior management attends regular meetings of the Board, providing presentations on operations and risk exposure and mitigation activities. Specific examples of risks primarily overseen by the full Board include, but are not limited to, legal risks, competition risks, industry risks, economic risks, business operations risks, commercial and regulatory compliance risks, quality risks, cybersecurity risks, reputational risks and risks related to acquisitions and dispositions.

Our Board committees are responsible for specific areas of risk oversight:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The Audit Committee regularly reviews with management and the independent auditors significant financial risk exposures and the processes management has implemented to monitor, control and report such exposures. Specific examples of risks primarily overseen by the Audit Committee include, but are not limited to, risks related to preparing our financial statements, disclosure controls and procedures, internal controls over financial reporting, accounting, financial, auditing, treasury and cybersecurity risks insofar as such cybersecurity risks relate to accounting, audit and financial matters.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The Compensation Committee assists the Board in fulfilling its oversight responsibilities regarding the management of risks arising from our compensation policies and programs.

------

**<u>[**Table of Contents**](#ic2d59f9bf5e7474b9ef29aaf75ccdc2b_7)</u>**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The Nominating and Corporate Governance Committee assists the Board in fulfilling its oversight responsibilities regarding the management of risks associated with Board organization, membership and structure; as well as the Company's environmental and social responsibility policies and practices, succession planning, and corporate governance.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The Compliance, Quality and Risk Committee assists the Board in fulfilling its oversight responsibilities regarding the management of risks relating to the Company's Code of Conduct, compliance with applicable U.S. Food and Drug Administration requirements and international law, compliance program, cybersecurity policy, procedures and risk mitigation and enterprise risk management and control activities except to the extent to which such functions relate to accounting, audit and financial matters for which the Audit Committee is responsible.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The Strategy Committee assists the Board in fulfilling its oversight responsibilities regarding the management of risks relating to potential mergers, acquisitions, divestitures, joint ventures and other key strategic transactions outside the ordinary course of the Company's business.

Our Board is apprised by the chairperson of each Board committee of significant risks and management's responses via periodic updates at regularly scheduled Board meetings. The leadership structure of our Board supports the Board's effective oversight of our risk management.

**Board Evaluations**

In accordance with the Company's Corporate Governance Guidelines, the Board of Directors and committees conduct annual self-evaluations to assess the qualifications, attributes, skills and experience represented on the Board and to determine whether the Board and its committees are functioning effectively. The Nominating and Corporate Governance Committee receives input on the Board's performance from directors and, through its Chair, discusses the input with the full Board and oversees the full Board's review of its performance. The self-assessments focus on the Board's and committees' contribution to the Company and on areas in which the Board or management believes that the Board or any of its committees could improve. The Board and the Nominating and Corporate Governance Committee use the self-evaluations in making determinations regarding which directors will be nominated for election at the Annual Meeting. The Board and committee evaluation process also informs Board and committee composition, which includes evolution of the director skills and experience qualifications criteria to meet the current and anticipated needs of the business.

**PROPOSAL TWO—RATIFICATION OF APPOINTMENT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM**

The Audit Committee of the Board has selected Deloitte & Touche LLP as the independent registered public accounting firm to perform the audit of the Company's financial statements for the year ending December 31, 2026. Deloitte & Touche LLP has audited the Company's financial statements since 2002.

The Board is asking the stockholders to ratify the selection of Deloitte & Touche LLP as the Company's independent registered public accounting firm for 2026. Although not required by law, the rules of NASDAQ or the Company's Bylaws, the Board is submitting the selection of Deloitte & Touche LLP to the stockholders for ratification as a matter of good corporate practice. If the stockholders fail to ratify the selection, the Audit Committee may reconsider whether it should appoint another independent registered public accounting firm. Even if the selection is ratified, the Audit Committee, in its discretion, may select a different registered public accounting firm at any time during the year if it determines that such a change would be in the best interests of the Company and its stockholders.

Representatives of Deloitte & Touche LLP are expected to be present at the meeting. They will have an opportunity to make a statement if they desire to do so and will be available to respond to appropriate questions from the Company's stockholders.

**Board of Directors' Recommendation**

**THE BOARD RECOMMENDS THAT YOU VOTE <u>FOR</u> THE RATIFICATION OF THE SELECTION OF DELOITTE & TOUCHE LLP AS THE COMPANY'S INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR FISCAL YEAR 2026.**

In addition to retaining Deloitte & Touche LLP to audit the Company's financial statements for 2025, the Audit Committee retained Deloitte & Touche LLP to provide audit-related services in 2025. The Audit Committee understands the need for Deloitte & Touche LLP to maintain objectivity and independence in its audits of the Company's financial statements. The Audit Committee evaluates Deloitte's qualifications, performance and independence and presents its conclusions to the full Board on an annual basis.

**REPORT OF THE AUDIT COMMITTEE OF THE BOARD OF DIRECTORS**

Management has the primary responsibility for maintaining effective internal control over financial reporting and for preparing AtriCure's financial statements. AtriCure's independent registered public accounting firm is responsible for performing independent audits of AtriCure's financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States) and AtriCure's internal control over financial reporting based on criteria established in *Internal Control – Integrated Framework (2013)* issued by the Committee of Sponsoring Organizations of the Treadway Commission. The Audit Committee's responsibilities include monitoring and oversight of corporate accounting and financial reporting processes on behalf of the Board of Directors. In fulfilling its responsibilities, the Audit Committee reviewed with management the audited financial statements included in AtriCure's Annual Report on Form 10-K, including a discussion of significant accounting principles, the reasonableness of significant estimates and judgments made in preparing the financial statements and the clarity of disclosures in the financial statements. In addition, the Audit Committee discussed with the Chief Executive Officer and the Chief Financial Officer of AtriCure the certifications required to be given by such officers in connection with AtriCure's Annual Report on Form 10-K pursuant to the Sarbanes-Oxley Act of 2002 and the Securities and Exchange Commission rules adopted thereunder, including the subject matter of such certifications and the procedures followed by such officers and other management in connection with giving such certifications. The Audit Committee's responsibilities are set forth in a written charter, a copy of which is available on our website at ir.atricure.com under "Corporate Governance".

The Audit Committee is responsible for reviewing, approving and managing the engagement of AtriCure's independent registered public accounting firm, including the scope, extent and procedures of the annual audit and compensation to be paid thereof, and all other matters the Audit Committee deems appropriate, including the independent registered public accounting firm's accountability to the Board of Directors and the Audit Committee. The Audit Committee reviewed and discussed with AtriCure's independent registered public accounting firm its judgments as to the acceptability as well as the appropriateness of AtriCure's application of accounting principles and such other matters as are required to be discussed with the independent registered public accounting firm by the Public Company Accounting Oversight Board, the Securities and Exchange Commission and other applicable law and listing standards. AtriCure's independent registered public accounting firm is responsible for expressing an opinion on the conformity, in all material respects, of AtriCure's financial statements with accounting principles generally accepted in the United States of America. In addition, the Audit Committee has received the written disclosures and the letter from the independent registered public accounting firm required by applicable requirements of the Public Company Accounting Oversight Board regarding the independent registered public accounting firm's communications with the Audit Committee concerning independence, has discussed with AtriCure's independent registered public accounting firm its independence from management and AtriCure and has considered the compatibility of non-audit services with the independence of AtriCure's independent registered public accounting firm.

The Audit Committee discussed with AtriCure's independent registered public accounting firm the overall scope and plans for its audit. The Audit Committee meets with the independent registered public accounting firm to discuss the results of its examinations, its evaluation of the effectiveness of AtriCure's internal control over financial reporting and the overall quality of AtriCure's financial reporting. The Audit Committee held five meetings during the year ended December 31, 2025.

In reliance on the reviews and discussions referred to above, the Audit Committee recommended to the Board of Directors that the audited financial statements be included in AtriCure's Annual Report on Form 10-K for the year ended December 31, 2025 for filing with the Securities and Exchange Commission.

**PROPOSAL THREE—AMENDMENT TO 2023 STOCK INCENTIVE PLAN** 

Based on the recommendation of the Compensation Committee, the Board of Directors voted to approve and recommend, subject to the approval of stockholders, an amendment to the 2023 Stock Incentive Plan. The amendment would provide an increase of 1,500,000 shares of common stock authorized for issuance under the 2023 Stock Incentive Plan, from 4,500,000 shares to 6,000,000 shares. The increase in the total number of shares of common stock authorized for issuance with respect to incentive stock options in accordance with the Internal Revenue Code (Code) is also 1,500,000. No other provisions of the 2023 Stock Incentive Plan are being amended at this time. The 2023 Stock Incentive Plan as it is proposed to be amended and restated would allow us to continue to attract and retain experienced, high quality and high performing directors, executives and other employees with equity incentives. If we cannot offer equity-based compensation, we may have to increase our use of cash compensation, which could have an adverse impact on our business plans and operations.

The Amended and Restated 2023 Stock Incentive Plan (Amended 2023 Plan) document is attached as <u>Annex A</u>. Set forth below are: a summary of the principal features of the Amended 2023 Plan and a description of the U.S. federal income tax consequences under the Amended 2023 Plan. The summary of principal features of the Amended 2023 Plan does not purport to be complete and it is qualified in its entirety by reference to <u>Annex A</u>.

**Summary of the Amended 2023 Plan** 

*Overview and Purpose.* The Board believes that stock-based awards are an important element of the Company's compensation programs. The Amended 2023 Plan promotes the Company's compensation philosophy and objectives by: (i) providing long-term incentives to those persons with responsibility for the success and growth of the Company; (ii) motivating participants to achieve the long-term success and growth of the Company; (iii) providing a vehicle to tie a significant portion of compensation to the long-term performance of the Company's shares; (iv) enabling the Company to attract and retain skilled and qualified officers, other employees, directors and consultants who are expected to contribute to the Company's success in a competitive market for such individuals (v) facilitating ownership of the Company's shares and (vi) aligning the personal interests of officers, employees and others in the Company's long-term growth and profitability with the interests of the Company's stockholders.

As of March 31, 2026, approximately 1,138,050 shares remained available for grant. Information on the total number of shares available under the Company's existing equity compensation plans and subject to outstanding options and rights is presented in the Equity Compensation table on page [25](#i379d3acd33d04326bf2f9b6bb36d768e_31049).

The Board approved the Amended 2023 Plan (subject to stockholder approval) to provide an additional 1,500,000 shares of stock-based awards to be granted under it, which we believe would provide a sufficient number of shares to enable the Company to make awards at a value that is consistent with historical average annual rates, adjusted to account for the Company's anticipated increased headcount, for at least two years. The Compensation Committee determined that reserving shares sufficient for approximately two years of new awards at historical grant rates is in line with the practices of other companies in our peer group. However, the actual number of shares subject to awards under the Amended 2023 Plan is dependent on a number of factors, including the future trading price of our common stock, our promotion and hiring activity, our retention needs and market practices within our industry. As a result, the share reserve under the Amended 2023 Plan could last for a longer or shorter period of time than currently expected.

All stock incentive awards to the Company's most highly compensated executives that may be made over the next few years are expected to be granted under the Amended 2023 Plan. The Amended 2023 Plan allows the Company the flexibility to grant a variety of stock and stock-based awards, including stock options and stock appreciation rights, granted separately or in tandem with each other, restricted shares and restricted share units, both time vested or conditioned on the attainment of performance goals and unrestricted shares.

If stockholders approve the Amended 2023 Plan, equity awards on or after May 18, 2026 will be granted under the terms of the Amended 2023 Plan. If our stockholders do not approve the Amended 2023 Plan, the existing 2023 Stock Incentive Plan will continue in its current (pre-amendment) form. However, the Company may have insufficient authorized shares in the near future to make equity awards to eligible individuals and will consider alternative methods of compensation for its key personnel, which may include equity-based but cash-settled incentives. Failure of the stockholders to approve this proposal will not affect the rights of existing holders or the awards previously granted. If our stockholders approve the Amended 2023 Plan, the Company intends to file, pursuant to the Securities Act of 1933, as amended, a registration statement on Form S-8 to register 1,500,000 additional shares available for issuance under the Amended 2023 Plan.

*Shares Subject to the Amended 2023 Plan.* Stockholders approved the 2023 Stock Incentive Plan at the 2023 Annual Meeting of Stockholders. The aggregate number of shares of common stock that may be issued under the 2023 Stock

------

**<u>[**Table of Contents**](#ic2d59f9bf5e7474b9ef29aaf75ccdc2b_7)</u>**

Incentive Plan as approved by stockholders in 2023 was 2,286,674. The aggregate amount consists of 1,000,000 shares of our common stock plus the number of shares of our common stock that remained available for awards under the 2014 Stock Incentive Plan on the day the 2023 Stock Incentive Plan was approved by our stockholders. Stockholders have amended the 2023 Stock Incentive Plan twice to increase the number of shares of common stock authorized for issuance thereunder: in 2024 to increase the number of authorized shares by 1,800,000 and in 2025 to increase the number of authorized shares by 1,700,000. After giving effect to this amendment, the aggregate number of common shares that may be issued under the Amended 2023 Plan, assuming approval by stockholders, is 7,286,674. As of the record date, March 26, 2026, the market value of one share of our common stock that could be issued under the 2023 Stock Incentive Plan is $30.04.

If any award granted under the Amended 2023 Plan or under the 2014 Stock Incentive Plan (the "Prior Plan") expires, terminates, is canceled or is forfeited without being settled or exercised, or if an award is settled in cash or otherwise without the issuance of shares, shares of our common stock subject to such award will be made available for future grant under the Amended 2023 Plan. If shares issuable upon vesting or settlement of an award are withheld by the Company, or if shares owned by a participant are surrendered or tendered to the Company, in payment of taxes required to be withheld in respect of the award, such shares will not be made available for future grant under the Amended 2023 Plan. If any shares are surrendered or tendered to pay the exercise price of an option, or to satisfy withholding taxes owed with respect to an option or stock appreciation right, or if any shares subject to a stock appreciation right are not issued in connection with its stock settlement on exercise thereof, or if any shares are reacquired by us on the open market or otherwise using cash proceeds from the exercise of options, such shares will not be made available for grant under the Amended 2023 Plan.

*Limitations*. No more than an aggregate of 6,000,000 shares of our common stock plus the number of common shares remaining available for issuance under the 2014 Stock Incentive Plan may be issued in the aggregate in respect of incentive stock options under the Amended 2023 Plan. The maximum grant date fair value of equity awards that may be awarded to a non-employee director under the Amended 2023 Plan during any one fiscal year, taken together with any cash fees paid to such non-employee director during such fiscal year, will be $1,000,000; provided that our Board of Directors may make exceptions for a non-executive chairman of the Board who does not participate in the decision to award such compensation, and for special projects and ad hoc committee appointments deemed appropriate by the Board from time to time.

*Eligibility.* Any of our employees, directors, officers, consultants or advisors and those of our affiliates will be eligible for awards under the Amended 2023 Plan. The Committee has the sole authority to determine who will be granted an award under the Amended 2023 Plan. As of March 1, 2026, approximately 1,375 employees (including seven executive officers) and eight non-employee directors were eligible to be selected by our Compensation Committee for awards under the Amended 2023 Plan.

*Administration.* The Amended 2023 Plan will be administered by a committee of independent directors approved by our Board of Directors (or, if no committee has been appointed, it shall be administered by the Board of Directors). Our Board has designated our Compensation Committee to administer the Amended 2023 Plan. The Compensation Committee will have the authority to determine the terms and conditions of any agreements evidencing any awards granted under the Amended 2023 Plan and to establish, amend, suspend or waive any rules and regulations relating to the Amended 2023 Plan. The Compensation Committee will have full discretion to administer and interpret the Amended 2023 Plan and to determine, among other things, the time or times at which the awards may be exercised and whether and under what circumstances an award may be exercised.

Over the past several years, the Compensation Committee has determined award recipients and has granted retention awards approximately two months after the end of the Company's fiscal year, on or about March 1. In addition, the Compensation Committee has designated a limited value of shares annually for grant throughout the year for hiring, recognition and retention of employees. The Committee determines grants of awards and identifies recipients of awards based on a variety of considerations, including, without limitation: (i) the Company's need to attract and retain key personnel; (ii) the Company's objective of providing a means pursuant to which participants may be paid incentive compensation, including incentive compensation measured by reference to the value of the Company's common stock; and (iii) the Company's objective of strengthening the commitment of award recipients to the welfare of the Company and its affiliates and aligning their interests with those of the Company's stockholders.

*Adjustments.* If there is any change in our corporate capitalization, the Compensation Committee in its sole discretion may make substitutions or adjustments to the number of shares reserved for issuance under the Amended 2023 Plan, the number of shares covered by awards then-outstanding under the Amended 2023 Plan, the limitations on awards under the Amended 2023 Plan, and/or the exercise price of outstanding options and such other equitable substitution or adjustments as it may determine to be equitable.

------

**<u>[**Table of Contents**](#ic2d59f9bf5e7474b9ef29aaf75ccdc2b_7)</u>**

*Awards Available for Grant.* The Compensation Committee may grant awards of nonqualified stock options, incentive (qualified) stock options, stock appreciation rights, restricted stock awards, restricted stock units, other stock-based awards, performance compensation awards (including cash bonus awards) or any combination of the foregoing.

*Options*. The Compensation Committee is authorized to grant options to purchase shares of common stock that are either "qualified," meaning they are intended to satisfy the requirements of Section 422 of the Code for incentive stock options, or "nonqualified," meaning they are not intended to satisfy the requirements of Section 422 of the Code. Options granted under the Amended 2023 Plan will be subject to the terms and conditions established by the Compensation Committee. Under the terms of the Amended 2023 Plan, the exercise price of the options will not be less than the fair market value of our common stock at the time of grant. Options granted under the Amended 2023 Plan will be subject to such terms, including the exercise price and the conditions and timing of exercise, as may be determined by the Committee and specified in the applicable award agreement. The maximum term of an option granted under the Amended 2023 Plan will be ten years from the date of grant (or five years in the case of a qualified option granted to a 10% stockholder). Payment in respect of the exercise of an option may be made in cash or by check, by surrender of unrestricted shares (at their fair market value on the date of exercise), or through a "net exercise," or the Compensation Committee may, in its discretion and to the extent permitted by law, allow such payment to be made through a broker-assisted cashless exercise mechanism or by such other method as the Committee may determine to be appropriate. In-the-money options that have not been exercised by the option's expiration date will be automatically exercised by means of a net exercise.

*Stock Appreciation Rights*. The Compensation Committee is authorized to award stock appreciation rights (referred to in this proxy statement as SARs) under the Amended 2023 Plan. SARs will be subject to the terms and conditions established by the Compensation Committee and reflected in the award agreement. A SAR is a contractual right that allows a participant to receive, in the form of either cash, shares or any combination of cash and shares, the appreciation, if any, in the value of a share over a certain period of time. An option granted under the Amended 2023 Plan may include SARs, and SARs may also be awarded to a participant independent of the grant of an option. SARs granted in connection with an option shall be subject to terms similar to the option corresponding to such SARs. In-the-money SARs that have not been exercised by the SAR's expiration date will be automatically settled at that time.

*Restricted Stock*. The Compensation Committee is authorized to award restricted stock under the Amended 2023 Plan. Awards of restricted stock will be subject to the terms and conditions established by the Compensation Committee. Restricted stock is common stock that is subject to such restrictions as may be determined by the Compensation Committee for a specified period. If any dividends in respect of restricted stock have been withheld by the Company during the restricted period, those dividends will be paid in cash or, at the discretion of the Committee, in common stock when the restricted period ends, unless the restricted stock has previously been forfeited.

*Restricted Stock Unit Awards*. The Compensation Committee is authorized to award restricted stock unit awards. Restricted stock unit awards will be subject to the terms and conditions established by the Compensation Committee. At the election of the Compensation Committee, the participant will receive a number of shares of common stock equal to the number of units earned or an amount in cash equal to the fair market value of that number of shares at the expiration of the period over which the units are to be earned or at a later date selected by the Compensation Committee. If a restricted stock unit award agreement so provides, the restricted stock unit award will be credited with dividend equivalents in respect of the common stock underlying the restricted stock units. Any such dividend equivalents will be paid in cash or, at the discretion of the Committee, in common stock when the restricted period ends, unless the restricted stock has previously been forfeited.

*Other Stock-Based Awards*. The Compensation Committee is authorized to award other stock-based awards having terms and conditions as determined by the Committee. These awards may be granted either alone or in tandem with other awards.

*Performance Compensation Awards*. The Compensation Committee may grant any award other than a stock option or a SAR under the Amended 2023 Plan in the form of a performance compensation award by conditioning the vesting of the award on the satisfaction of certain performance goals. The Committee may consult with senior management prior to establishing performance goals with reference to one or more of the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• net earnings or net income (before or after taxes);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• basic or diluted earnings per share (before or after taxes);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• net revenue or net revenue growth;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• gross revenue or gross revenue growth;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• gross profit or gross profit growth;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• net operating profit (before or after taxes);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• return measures (including, but not limited to, return on investment, assets (including net assets), capital, invested capital, equity or sales);

------

**<u>[**Table of Contents**](#ic2d59f9bf5e7474b9ef29aaf75ccdc2b_7)</u>**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• cash flow measures (including, but not limited to, operating cash flow, free cash flow and cash flow return on capital);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• earnings before or after taxes, interest, depreciation, and/or amortization;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• gross or operating margins;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• productivity ratios;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• share price (including, but not limited to, growth measures and total stockholder return);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• expense targets;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• operating efficiency;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• objective measures of customer satisfaction;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• working capital targets;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• measures of economic value added;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• inventory control;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• stockholder return;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• sales;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• enterprise value;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• competitive market metrics;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• employee retention;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• timely completion of new product rollouts;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• timely launch of new facilities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• objective measures of personal targets, goals or completion of projects (including, but not limited to, succession and hiring projects, completion of specific acquisitions, reorganizations or other corporate transactions, expansions of specific business operations and meeting divisional or project budgets);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any other objective or subjective criteria, including individual performance criteria, as determined by the Committee; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any combination of the foregoing.

Performance criteria also may include measures related to environmental, social and/or governance matters, including, without limitation, matters related to people, retention, hiring, headcount and diversity, equity and inclusion.

*Minimum Vesting Requirements*. Awards granted under the Amended 2023 Plan are subject to a minimum vesting period of one year from the date of grant. However, the Compensation Committee may provide for acceleration of award vesting, including upon a change in control, death, disability or retirement. The following are exempt from such minimum vesting requirement: cash-based awards, substitute awards, shares delivered in lieu of fully vested cash awards, awards to eligible directors that vest on the earlier of the one-year anniversary of the date of grant and the next annual meeting of stockholders that is at least 50 weeks after the immediately preceding year's annual meeting and awards granted with respect to a maximum of 5% of the available share reserve authorized for issuance under the Amended 2023 Plan.

*Transferability*. Each award may be exercised during the participant's lifetime only by the participant or, if permissible under applicable law, by the participant's legal guardian or representative and may not be otherwise transferred or encumbered by a participant other than by will or by the laws of descent and distribution, except that awards (other than incentive stock options) may in the sole discretion of the Compensation Committee be transferred without consideration and on such other terms and conditions as set forth by the Compensation Committee.

*Amendment*. Our Board of Directors may amend, suspend or terminate the Amended 2023 Plan at any time; however, stockholder approval to amend the Amended 2023 Plan may be necessary if the law so requires. Specifically, stockholder approval is required if we want to amend the plan to increase the number of shares subject to the Amended 2023 Plan. Also, we would need stockholder approval if the Compensation Committee intended to amend an award agreement in a way that would either reduce the exercise price or strike price of a stock option or SAR, or cancel and replace an outstanding stock option or SAR with a new option or SAR or other award or cash in a way that would constitute a "repricing" for financial statement reporting purposes or otherwise fail to qualify for equity accounting treatment, or take any other action that would be considered a "repricing" for purposes of any stockholder approval rules of any securities exchange or inter-dealer quotation system on which our securities are listed or quoted, and in either case was not otherwise permitted by the provisions of the plan relating to adjustments of awards in the case of changes in our capital structure and similar events. No amendment, suspension or termination will materially and adversely affect the rights of any participant or recipient of any award without the consent of the participant or recipient.

*Recoupment Policy*. Awards are subject to forfeiture or repayment pursuant to the terms of any applicable compensation recoupment or recovery policy adopted by the Company, Committee or Board, including any policy adopted to comply with federal securities regulations or the rules of any stock exchange on which our shares are traded.

**U.S. Federal Income Tax Consequences**

The following is a general summary of the material U.S. federal income tax consequences of the grant, vesting and exercise of awards under the Amended 2023 Plan and the disposition of shares acquired pursuant to the exercise of such awards and is intended to reflect the current provisions of the Code and the regulations thereunder. This summary is not intended to be a complete statement of applicable law, nor does it address foreign, state, local, payroll or excise tax

------

**<u>[**Table of Contents**](#ic2d59f9bf5e7474b9ef29aaf75ccdc2b_7)</u>**

considerations. Moreover, the U.S. federal income tax consequences to any particular participant may differ from those described herein by reason of, among other things, the particular circumstances of such participant.

*Options*. The Code requires that, for treatment of an option as a qualified option, shares of our common stock acquired through the exercise of a qualified option cannot be disposed of before the later of (i) two years from the date of grant of the option and (ii) one year from the date of exercise. Holders of qualified options will generally incur no federal income tax liability at the time of grant or upon exercise of those options. However, the spread at exercise will be an "item of tax preference," which may give rise to "alternative minimum tax" liability for the taxable year in which the exercise occurs. If the holder does not dispose of the shares before two years following the date of grant and one year following the date of exercise, the difference between the exercise price and the amount realized upon disposition of the shares will constitute long-term capital gain or loss, as the case may be. Assuming both holding periods are satisfied, no deduction will be allowed to us for federal income tax purposes in connection with the grant or exercise of the qualified option. If, within two years following the date of grant or within one year following the date of exercise, the holder of shares acquired through the exercise of a qualified option disposes of those shares, the participant will generally realize taxable compensation at the time of such disposition equal to the difference between the exercise price and the lesser of the fair market value of the share on the date of exercise or the amount realized on the subsequent disposition of the shares, and that amount will generally be deductible by us for federal income tax purposes, subject to the possible limitations on deductibility under Sections 162(m) and 280G of the Code for compensation paid to certain executives designated in those Sections. Finally, if an otherwise qualified option becomes first exercisable in any one year for shares having an aggregate value in excess of $100,000 (based on the grant date value), the portion of the qualified option in respect of those excess shares will be treated as a non-qualified stock option for federal income tax purposes. No income will be realized by a participant upon grant of a non-qualified stock option. Upon the exercise of a non-qualified stock option, the participant will recognize ordinary compensation income in an amount equal to the excess, if any, of the fair market value of the underlying exercised shares over the option exercise price paid at the time of exercise, regardless of whether the exercise price is paid in cash, shares or other property. We will be able to deduct this same amount for U.S. federal income tax purposes, but such deduction may be limited under Sections 162(m) and 280G of the Code for compensation paid to certain executives designated in those Sections.

*Restricted Stock*. A participant will not be subject to tax upon the grant of an award of restricted stock unless the participant otherwise elects to be taxed at the time of grant pursuant to Section 83(b) of the Code. On the date an award of restricted stock becomes transferable or is no longer subject to a substantial risk of forfeiture, the participant will have taxable compensation equal to the difference between the fair market value of the shares on that date over the amount the participant paid for such shares, if any, unless the participant made an election under Section 83(b) of the Code to be taxed at the time of grant. If the participant made an election under Section 83(b), the participant will have taxable compensation at the time of grant equal to the difference between the fair market value of the shares on the date of grant over the amount the participant paid for such shares, if any, regardless of whether the amount is paid in cash, shares or other property. (Special rules apply to the receipt and disposition of restricted shares received by officers and directors who are subject to Section 16(b) of the Securities Exchange Act of 1934.) We will be able to deduct, at the same time as it is recognized by the participant, the amount of taxable compensation to the participant for U.S. federal income tax purposes, but such deduction may be limited under Sections 162(m) and 280G of the Code for compensation paid to certain executives designated in those Sections.

*Restricted Stock Units*. A participant of an RSU (whether time-vested or subject to achievement of performance goals) will generally not be subject to income taxation at grant. Instead, the participant will have taxable compensation on the fair market value of the shares (or the amount of cash) received on the date of delivery. Gain or loss resulting from any subsequent sale of shares delivered to participant will be treated as long- or short-term capital gain or loss depending on the holding period. If any dividend equivalent amounts are paid to the participant, they will be includable in the participant's income as additional compensation and not as dividend income. We will be able to deduct, at the same time as it is recognized by the participant, the amount of taxable compensation to the participant for U.S. federal income tax purposes, but such deduction may be limited under Sections 162(m) and 280G of the Code for compensation paid to certain executives designated in those Sections.

*Stock Appreciation Rights*. No income will be realized by a participant upon grant of a SAR. Upon the exercise of a SAR, the participant will recognize ordinary compensation income in an amount equal to the fair market value of the payment received in respect of the SAR. We will be able to deduct this same amount for U.S. federal income tax purposes, but such deduction may be limited under Sections 162(m) and 280G of the Code for compensation paid to certain executives designated in those Sections.

*Other Stock-Based Awards*. A participant will have taxable compensation equal to the difference between the fair market value of the shares on the date the award is settled (whether in shares or cash, or both) over the amount the participant paid for such shares, if any. We will be able to deduct, at the same time as it is recognized by the participant, the

------

amount of taxable compensation to the participant for U.S. federal income tax purposes, but such deduction may be limited under Sections 162(m) and 280G of the Code for compensation paid to certain executives designated in those Sections.

*Cash Awards*. Any cash received pursuant to a cash award will be treated as compensation income received by the participant generally in the year in which the participant receives such cash, and such amount will be deductible by us in the prior or same year, but such deduction may be limited under Sections 162(m) and 280G of the Code for compensation paid to certain executives designated in those Sections.

**The foregoing is a general summary of the material U.S. federal income tax consequences of the Amended 2023 Plan and is intended to reflect the current provisions of the Internal Revenue Code and the regulations thereunder. This summary is not intended to be a complete statement of applicable law, nor does it address foreign, state, local and payroll tax considerations. Moreover, the U.S. federal income tax consequences to any particular participant may differ from those described herein by reason of, among other things, the particular circumstances of such participant. Each eligible employee who is outside the United States or is otherwise not a U.S. taxpayer should seek, and must depend upon, the advice of his or her own independent legal and tax advisor or advisors in all non-U.S. jurisdictions relevant to such employee. The foregoing should not be considered as tax advice and each eligible employee is advised to consult his or her own independent tax advisor.**

**PROPOSAL FOUR—AMENDMENT TO 2018 EMPLOYEE STOCK PURCHASE PLAN**

On February 12, 2026, the Compensation Committee of the Board of Directors approved, subject to the approval of stockholders, an amendment to the 2018 Employee Stock Purchase Plan (the "ESPP"). If approved by stockholders, the amendment would increase the maximum amount of shares authorized for issuance under the ESPP from 1,250,000 to 2,000,000. Specifically, the amendment requires the restatement of the first sentence of Section 13.1 of the ESPP as follows: "The maximum number of shares of Common Stock reserved as authorized for the grant of options under the Plan is 2,000,000 shares." No other provisions of the ESPP are being amended at this time.

The Board of Directors believes that the ESPP promotes the interests of the Company and its stockholders by encouraging employees of the Company to become stockholders, and therefore promote the Company's growth and success. The Board of Directors also believes that the opportunity to acquire a proprietary interest in the success of the Company through the acquisition of shares of common stock pursuant to the ESPP is an important aspect of the Company's ability to attract and retain highly qualified and motivated employees. The ESPP is intended to qualify as "employee stock purchase plan" meeting the requirements of Section 423 of the Internal Revenue Code.

Set forth below are: (i) a summary of the principal features of the ESPP; and (ii) a description of the U.S. federal income tax consequences under the ESPP. The following description is a summary of the ESPP and is qualified in its entirety by reference to the applicable provisions of the ESPP, included as <u>Annex B</u>. Any stockholder who wishes to obtain a copy of the actual plan document may do so by written request to: Chief Financial Officer, AtriCure, Inc., 7555 Innovation Way, Mason, Ohio 45040.

**Summary of the ESPP**

*Overview and Purpose.* The purpose of the ESPP is to provide eligible employees (as defined in the ESPP) an opportunity to acquire stock ownership in the Company in order to grow with the Company, to help employees provide for their future security, to encourage them to remain employed by the Company, and to help align the interests of the employees with those of the Company's stockholders.

*Eligibility.* Participation is limited to employees of the Company or a Participating Subsidiary (as defined in the ESPP). Employees are generally eligible to participate in the ESPP, provided they customarily are employed at least 20 hours per week and more than five months a year and satisfy the enrollment procedures and other requirements set forth in the ESPP. No employee shall be granted any options under the ESPP if, after giving effect to such grant, the employee would own (or be deemed to own) 5% or more of the Company's voting power or value of classes of stock of the Company or any of its subsidiaries. No employee will be able to purchase shares to the extent that such employee would purchase $25,000 of market value of the shares in any calendar year. The Compensation Committee may exclude employees who are considered "highly compensated employees" within the meaning of Section 414(q) of the Code or a subset of such highly compensated employees. In addition, employees who are citizens or residents of a foreign jurisdiction will not be eligible to participate in the ESPP if the grant of an option under the ESPP is prohibited under the laws of the foreign jurisdiction or compliance with the laws of the foreign jurisdiction will cause the ESPP to violate the terms of Section 423 of the Internal Revenue Code. Approximately 1,070 employees are eligible to participate in the ESPP as of December 31, 2025.

The purpose of the ESPP is to provide eligible employees an opportunity to acquire stock ownership in the Company in order to grow with the Company, to help employees provide for their future security, to encourage them to remain employed by the Company and to help align the interests of the employees with those of the Company's stockholders.

*Offerings.* The ESPP allows eligible employees to purchase shares of our common stock during certain offering periods, which generally consist of a series of separate consecutive six-month offerings with each offering period beginning on January 1 and July 1, subject to the right of the Compensation Committee in its sole discretion to sooner terminate the ESPP or to change the commencement date or term of any offering period. The Compensation Committee may change the duration of future offerings and/or the start and end dates of future offering periods, subject to a maximum of 27 months and to the extent permitted under Section 423 of the Code.

*Shares Available under the ESPP.* A total of 500,000 shares of common stock were initially authorized and reserved for issuance under the ESPP. Stockholders amended the 2018 Plan in 2023 to increase the number of shares of common stock authorized for issuance by 750,000. As of December 31, 2025, 295,273 shares remained available for issuance under the ESPP. If approved by stockholders, the amendment would increase the maximum amount of shares authorized for issuance under the ESPP from 1,250,000 to 2,000,000.

*Participation.* Participation in the ESPP is entirely voluntary. Eligible employees wishing to participate in the ESPP are required to submit enrollment materials to the Company prior to the commencement of an offering that authorizes the Company to deduct from such employee's payroll.

------

**<u>[**Table of Contents**](#ic2d59f9bf5e7474b9ef29aaf75ccdc2b_7)</u>**

*Payroll Deductions.* Participating employees may elect to have an amount between 1% and 10% of his or her Compensation (as defined in the ESPP) on each pay day occurring during an Offering Period (as defined in the ESPP) deducted from each paycheck. During the Offering Period, participating employees may increase or decrease the amount of his payroll deductions. The Company may limit the number of election changes made by the Participant. However, participating employees may decrease his payroll deductions to zero percent at any time during the Offering Period.

*Withdrawal.* Employees may receive a refund of all withholdings during an Offering Period by providing the Company with notice of their withdrawal at least five days before the last Trading Day (as defined in the ESPP) of the Offering Period.

*Re-Enrollment.* Participating employees will be automatically re-enrolled in the next Offering Period unless they advise the Company otherwise.

*Purchase of Shares.* On the last Trading Day of each Offering Period, each participant shall be granted an option to purchase a number of whole shares of common stock determined by dividing such participant's accumulated payroll deductions by the applicable purchase price. The purchase price shall be equal to 85% (or such greater percentage as designated by the Company) of the market price of the Company's common stock on the Purchase Date (as defined in the ESPP) or the first Trading Day of the Offering Period, whichever is lower. No participating employee shall purchase more than 2,500 shares of common stock during an Offering Period.

*Stockholder Rights.* Participating employees will have no rights as shareholders, including dividends or voting rights, with respect to any shares until such shares are actually purchased.

*Transferability.* Purchase rights granted to participating employees under the ESPP are not assignable or transferable (other than by will or laws of descent and distribution) and may be exercised only by the participating employee (or beneficiary) during his lifetime.

*Termination of Employment.* Upon an employee's termination of employment for any reason or if an employee is no longer an eligible employee, the employee will be deemed to have withdrawn from the ESPP and such employee's balance shall be paid to the employee or the employee's estate, if applicable.

*Termination and Amendment.* The Compensation Committee shall have the right to amend the ESPP at any time. Any amendment that increases the aggregate number of shares of the Company's common stock to be issued under the ESPP, as adopted by the Board of Directors, must be approved by a vote of the stockholders of the Company within twelve months before or after the adoption of such amendment by the Board of Directors. All other amendments to the ESPP will be subject to stockholder approval only to the extent required by applicable law or regulation. The Compensation Committee has the authority to make technical and administrative amendments to the ESPP for the sole purpose of carrying out its administrative responsibilities under the ESPP if such amendment does not require approval by the Company's stockholders or the Board of Directors.

The Compensation Committee has the right at any time to suspend or terminate the ESPP for any reasons. If the ESPP is terminated, the Compensation Committee may provide, in its discretion, either that the outstanding purchase rights will expire in accordance with the applicable Offering Period (or such earlier date as the Compensation Committee may specify), or that each participating employee's payroll deductions will be returned to the participant without interest.

If stockholders approve the amendment, AtriCure expects to file an amended and restated ESPP plan document exhibit with the Securities and Exchange Commission which will include the restatement of the first sentence of Section 13.1 of the ESPP described above.

*Effective Date and Term.* The ESPP was approved by stockholders at the 2018 Annual Meeting, and will be effective until May 22, 2028. The ESPP expires on the tenth anniversary of its effective date.

*Administration of the ESPP.* The ESPP is administered by the Board of Directors which has delegated the authority to administer the ESPP to the Compensation Committee, who may further delegate its authority to administer the ESPP.

*Corporate Transactions.* In the event of a merger or Change in Control (as defined in the ESPP), the Offering Period will be shortened and end before the consummation of the merger or the Change in Control.

*Resale Limitations.* The purpose of the ESPP is to provide common stock to employees for investment purposes and not for resale. However, employees may sell any common stock purchased under the ESPP, subject to any holding periods imposed by the ESPP, the Compensation Committee, or by applicable federal, state or foreign tax or securities laws.

**<u>[**Table of Contents**](#ic2d59f9bf5e7474b9ef29aaf75ccdc2b_7)</u>**

*New Plan Benefits.* Participation in the ESPP is voluntary, and we cannot presently determine the benefits or amounts that will be received pursuant to the ESPP in the future, as such amounts will depend on the amount of contributions eligible employees choose to make, the actual purchase price of shares in future offering periods and the market value of the common stock on various future dates. Non-employee directors are not eligible to participate in the ESPP. No rights have been granted and no shares of our common stock have been issued with respect to the additional 750,000 shares for which stockholder approval is being sought.

**Certain Federal Tax Consequences with Respect to Awards**

The following brief summary of the effect of U.S. federal income taxation upon the participating employee and the Company with respect to the shares purchased under the ESPP does not purport to be complete, and does not discuss the tax consequences of a participant's death or the income tax laws of any state, local or foreign country in which the participant may reside.

The ESPP is intended to be an "employee stock purchase plan" within the meaning of Section 423 of the Internal Revenue Code. The amounts deducted from the salary of a participating employee will constitute ordinary income taxable to the employee. The right to purchase shares of common stock under the ESPP will not have any U.S. federal income tax consequences to either the participating employee or the Company or any of its affiliates. The purchase of common stock under the ESPP will not have any immediate U.S. federal income tax consequences to the participating employee. The determination of U.S. federal income tax consequences depend on whether the shares purchased are disposed of after the expiration of one year after the date those shares are purchased by the participating employee and two years after first day of the Offering Period (referred to below as the "holding periods"). If the holding periods are met, 15% of the fair market value of the shares of common stock on the first day of the Offering Period (or such other percentage equal to the applicable purchase price discount), or, if less, the excess, if any, of the sale price of the shares at the time of such disposition or death over the total purchase price of the shares, will be treated as ordinary income and any additional gain will be treated as long-term capital gain. Neither the Company nor any of its affiliate employing the participating employee will be entitled to any U.S. federal income tax deduction with respect to the amount treated as long-term capital gain or as ordinary income as a result of the rules described above for shares disposed of after expiration of the holding periods.

If the shares are disposed of prior to the expiration of the holding periods (a "disqualifying disposition"), generally the excess of the fair market value of those shares on the Purchase Date over the aggregate purchase price will be ordinary income at the time of such disqualifying disposition. We will be able to deduct, at the same time as it is recognized by the participant, the amount of taxable compensation to the participant for U.S. federal income tax purposes, but such deductions may be limited under Section 162(m) and 280G of the Code for compensation paid to certain executives designated in those Sections. Any disposition proceeds in excess of the value of the shares at the exercise date will result in capital gain (or loss) to the participant and will not be deductible by us.

To the extent any (i) grant of an option to purchase shares, (ii) purchase of shares or (iii) disposition of shares purchased under the ESPP gives rise to any tax withholding obligation, the Compensation Committee or its delegate may implement appropriate procedures to ensure that such tax withholding obligations are met. Those procedures may include, without limitation, increased withholding from an employee's current compensation, cash payments to the Company by an employee, or a sale of a portion of the stock purchased under the ESPP, which sale may be required and initiated by the Company. Each participating employer shall give the Company prompt written notice of any disposition or other transfer of shares acquired pursuant to the exercise of an option acquired under the ESPP, if such disposition or transfer is made within two years after the date of grant or within one year after the exercise date.

**The foregoing is a general summary of the material U.S. federal income tax consequences of the ESPP and is intended to reflect the current provisions of the Internal Revenue Code and the regulations thereunder. This summary is not intended to be a complete statement of applicable law, nor does it address foreign, state, local and payroll tax considerations. Moreover, the U.S. federal income tax consequences to any particular participant may differ from those described herein by reason of, among other things, the particular circumstances of such participant. Each eligible employee who is outside the United States or is otherwise not a U.S. taxpayer should seek, and must depend upon, the advice of his or her own independent legal and tax advisor or advisors in all non-U.S. jurisdictions relevant to such employee. The foregoing should not to be considered as tax advice and each eligible employee is advised to consult his or her own independent tax advisor.**

**PROPOSAL FIVE—ADVISORY VOTE ON COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS**

The Dodd-Frank Wall Street Reform and Consumer Protection Act, enacted in July 2010 ("Dodd-Frank Act"), requires that we provide our stockholders with the opportunity to vote to approve, on a non-binding, advisory basis, the compensation of our named executive officers ("NEOs") as disclosed in this proxy statement in accordance with the compensation disclosure rules of the Securities and Exchange Commission ("Say on Pay").

As described in detail below under the heading "Compensation Discussion and Analysis" beginning on page [34](#ic2d59f9bf5e7474b9ef29aaf75ccdc2b_91) of this proxy statement, we seek to closely align the interests of our named executive officers with the interests of our stockholders. We structure our programs to discourage excessive risk-taking through a balanced use of compensation vehicles and metrics with an overall goal of delivering sustained long-term stockholder value while aligning our executives' interests with those of our stockholders. Further, our programs require that a substantial portion of each named executive officer's compensation be contingent on delivering performance results that benefit our stockholders. Our compensation programs are designed to reward our named executive officers for the achievement of short-term and long-term strategic and operational goals and the achievement of increased total stockholder return. Stockholders should note that, because the advisory vote on executive compensation occurs well after the beginning of the compensation year and because the different elements of our executive compensation programs are designed to operate in an integrated manner and to complement one another, in many cases it may not be appropriate or feasible to change our executive compensation programs in consideration of any one year's advisory vote on executive compensation by the time of the following year's annual meeting of stockholders.

***Stockholder Engagement and Say On Pay Response***

Annually, AtriCure offers stockholders the opportunity to cast an advisory vote on our executive compensation program. This annual vote is known as the "say-on-pay" proposal. At our annual meeting in May 2025, 78.9% of votes cast were in favor of the say-on-pay proposal covering our executive compensation program last year. Although a majority of stockholders expressed support for the compensation of the Company's named executive officers, the Compensation Committee values any additional stockholder feedback and endeavors to respond to stockholders' concerns. We regularly communicate with our stockholders to better understand their opinions on our business strategy and objectives and to obtain feedback regarding other matters of investor interest, such as executive compensation. See additional discussion of our most recent stockholder engagement efforts beginning on page 36. Additionally, the Compensation Committee obtains feedback, advice and recommendations on compensation best practices from its independent external compensation consultant and assesses the reports and publications of Institutional Shareholder Services and other proxy advisory firms. The Compensation Committee also reviews the Company's performance, the compensation practices of its peers and compensation surveys and other materials regarding general and executive compensation.

The vote on this matter is not intended to address any specific element of compensation; rather, the vote relates to the compensation of our named executive officers, as described in this proxy statement in accordance with the compensation disclosure rules of the Securities and Exchange Commission. This vote is advisory, which means that the vote is not binding on the Company, our Board of Directors or the Compensation Committee. The Board and the Compensation Committee will review and consider the voting results when making future decisions regarding our executive compensation program.

Accordingly, we ask our stockholders to approve, on an advisory basis, the compensation of the named executive officers, as disclosed in this proxy statement pursuant to the compensation disclosure rules of the Securities and Exchange Commission, including the Compensation Discussion and Analysis, the Summary Compensation Table and the other related tables and disclosure.

**Board of Directors' Recommendation**

**Ownership Guidelines**

Consistent with its compensation philosophy and the principle of aligning the interests of management and directors of the Company with the interests of its stockholders, the Board of Directors has implemented stock ownership guidelines for "Specified Officers" (defined in the guidelines as those officers required to file beneficial ownership reports with the SEC) and non-employee directors.

---

| | |
|:---|:---|
| **Beneficial Owner** | **Stock Ownership Guideline** |
| Chief Executive Officer | > 6x annual base salary |
| Specified Officers other than Chief Executive Officer | > 1x annual base salary |
| Non-employee directors | > 3x annual cash retainer\* |

---

\*Within three (3 years) of the later of the date of adoption of these guidelines or the appointment to the Board of Directors, each of the Company's non-employee directors is required to have a stock ownership position in the Company in an amount no less than three times their annual cash retainer for their director service, exclusive of any retainers for committee membership or committee chair service.

**Insider Trading Policy**

The Company has adopted an insider trading policy that governs the purchase, sale and/or other transactions of our securities by our directors, officers and employees. A copy of our insider trading policy is filed as Exhibit 19 to our Annual Report on Form 10-K for the fiscal year ended December 31, 2025. In addition, with regard to the Company trading its own securities, it is the Company's policy to comply with the federal securities laws and the applicable exchange listing requirements.

**Pledging and Hedging**

Our Insider Trading Policy prohibits directors, officers and employees, including named executive officers, from engaging in hedging or monetization transactions, such as prepaid variable forwards, equity swaps, forward-sale contracts, put options, collars and exchange funds, and from engaging in borrowing against AtriCure's securities held in a margin account, or pledging AtriCure's securities as collateral for a loan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Justin J. Noznesky, Chief Marketing and Strategy Officer

**Executive Summary**

Most of our compensation decisions are made in the first two months of the year, after review of our performance and the performance of our Chief Executive Officer and the other named executive officers. We believe the compensation of all of our named executive officers for 2025 aligned closely with both our performance in 2025 and the objectives of our executive compensation policies.

***2025 Business Highlights***

In 2025, we realized significant revenue growth and continued to advance strategic initiatives of product innovation, clinical science and expanding physician awareness and adoption through world-class training and education programs. We reported annual revenue growth of 14.9% over the prior year highlighted by accelerated adoption in our appendage management and pain management product lines, where recent product launches contributed to growth.

**Financial highlights and results for 2025 included:**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Revenue for 2025 was $534.5 million, an increase of $69.2 million or 14.9% compared to 2024 revenue. We experienced significant growth in our open ablation, appendage management and pain management product lines as a result of deepening market penetration, continuing physician adoption and several new product launches. Key products contributing to the increase in revenue in the United States were EnCompass<sup>®</sup> clamp in open ablation, cryoSPHERE MAX™ probe for post-operative pain management and AtriClip<sup>®</sup> FLEX-Mini™ device for appendage management in open chest procedures. Product development and regulatory milestones associated with each of these three products were previously featured as "Pillar Objectives" within our corporate incentive plan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Gross margin for 2025 increased approximately 29 basis points to 75.0%, driven by favorable product mix, offsetting increasing product costs and less favorable geographic mix.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our 2025 net loss improved by $33.3 million year over year, reflecting strong revenue growth, cost efficiencies and improving operating leverage. Additionally, we reported positive adjusted EBITDA (a non-GAAP measure)

------

**<u>[**Table of Contents**](#ic2d59f9bf5e7474b9ef29aaf75ccdc2b_7)</u>**

of $61.8 million in 2025, an improvement of $31.1 million or 98% over 2024 results. See <u>Annex C</u> for a discussion of management's use of adjusted EBITDA, a non-GAAP financial measure, and its reconciliation to GAAP measures.

**Key strategic and operational results for 2025 included:**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**• *PRODUCT INNOVATION.*** We continue to invest in research and development of new products and pursue regulatory approvals to market and sell globally across all franchises.

*Appendage management.* During the first quarter of 2025, FDA granted 510(k) clearance for the AtriClip<sup>®</sup> PRO-Mini<sup>™</sup> LAA Exclusion System. The device is built on the existing AtriClip platform, preloaded with the smallest surgical LAA management implant available in the market. The size reduction provides surgeons with enhanced visualization for precise, secure exclusion of the LAA during minimally invasive procedures. The AtriClip PRO-Mini device was launched in the United States during the second half of 2025.

*Pain management.* During the second quarter of 2025, FDA granted 510(k) clearance for the cryoICE<sup>®</sup> cryoXT™ probe, a cryoablation device designed specifically for Cryo Nerve Block therapy to alleviate pain in amputation patients. This device temporarily blocks pain by freezing target peripheral nerves, blocking the conduction pathway at the site of amputation. During the third quarter of 2025, this device was launched in the United States.

*Dual energy platform*. During the fourth quarter of 2025, we executed successful first-in-human treatments using our novel dual energy platform that integrates Pulsed Field Ablation (PFA) with Advanced Radiofrequency Ablation (Advanced RFA). The new platform delivers the benefits of both technologies, combining the proven safety and effectiveness of radiofrequency (RF) ablation with the efficiency of PFA. The Advanced RFA and PFA technologies are not yet approved for use in any market. We expect to initiate a clinical trial in the coming year, marking a key milestone in our product development pipeline.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***• CLINICAL SCIENCE*.** We invest in studies to expand labeling claims, support various indications for our products and publish clinical data for therapies and procedures involving our products. During 2025, we supported the publication of 13 articles and 15 congress abstracts featuring clinical studies with our product.

*LeAAPS.* The <u>L</u>eft <u>A</u>trial <u>A</u>ppendage <u>E</u>xclusion for <u>P</u>rophylactic <u>S</u>troke Reduction (LeAAPS) IDE clinical trial is designed to evaluate the effectiveness of prophylactic LAA exclusion using the AtriClip LAA Exclusion System for the prevention of ischemic stroke or systemic arterial embolism in cardiac surgery patients without pre-operative AF diagnosis who are at risk for these events. This prospective, multicenter, randomized trial evaluates safety at 30 days post-procedure to demonstrate no increased risk with LAA exclusion during cardiac surgery, and efficacy over a minimum follow-up of five years post procedure. In July 2025, we completed trial enrollment of 6,573 patients across 139 centers globally, well ahead of expected enrollment timelines for this clinical trial. Patient follow-up for a minimum of five years post procedure is required by the study protocol and remains ongoing.

*BoxX-NoAF.* The <u>Box</u> Lesion and Left Atrial Appendage E<u>X</u>clusion Procedure for the Prevention of <u>N</u>ew <u>O</u>nset of <u>A</u>trial <u>F</u>ibrillation (BoxX-NoAF) IDE trial evaluates the impact of concomitant ablation using the EnCompass clamp and LAA exclusion with the AtriClip system in non-AF patients for the reduction of post-operative AF (POAF) and Clinical AF. This prospective, multi-center, multi-national randomized trial evaluates safety at 30 days post-procedure for POAF and secondary effectiveness for Clinical AF through three years. The trial provides enrollment of up to 960 subjects at up to 75 sites globally. FDA approved the trial protocol during the fourth quarter of 2024 and during October 2025, we completed the first patient enrollment. Site initiation and enrollment is ongoing.

use of cadaver specimens, in addition to increasing the efficiencies of education and more cost-effective training alternatives.

***Stockholder Engagement - 2025 Stockholder Say on Pay Vote***

At each Annual Meeting of the Company's stockholders since 2013, the Company has held a "Say on Pay Vote," which is a non-binding advisory resolution stating that stockholders approve the compensation paid to the Company's Named Executive Officers. The Compensation Committee carefully considers the results of this vote each year. Company stockholders approved the Say on Pay Vote with strong support in recent years. At our annual meeting in May 2025, 78.9% of votes cast were in favor of the say-on-pay proposal covering our executive compensation program last year. The Compensation Committee considered these levels of support as it reviewed the Company's executive compensation programs and its decisions related to executive compensation.

Following the 2025 Annual Meeting, in response to a "say-on-pay" vote, the Board undertook an expanded stockholder engagement effort during which we reached out to our 25 largest institutional stockholders, representing approximately 71% of outstanding shares, resulting in meetings with six stockholders, representing 21% of outstanding shares. All meetings were led by the Chair of the Compensation Committee who was accompanied by our Chief Financial Officer. In these discussions we received valuable feedback, which helps inform our Board's discussions of our corporate governance practices, executive compensation program, policies, and practices for the year ahead.

Overall, the stockholders we met with through our stockholder engagement efforts supported our executive compensation program, and much of the dialogue related to the process and compensation philosophy of the Company and Compensation Committee as well as considerations specific to our CEO's special stock award granted in 2024. Additionally, feedback received from discussions with such stockholders included requests for enhanced disclosures of compensation plans similar to information provided in the additional proxy solicitation materials filed in 2025. The Compensation Committee carefully considered this feedback in the context of the Company's strategic plan, competitive positioning and recent operational and financial performance. After thorough deliberation, the Committee concluded that the fundamental structure of the current compensation program remains appropriately aligned with the Company's long-term strategy and the interests of stockholders. Specifically, the Compensation Committee determined that the evolution of our compensation programs meet the expectations of our stockholders. Further, in response to feedback from stockholders, the Compensation Committee has directed the enhancement of our proxy statement disclosures to provide stockholders with greater transparency into the relationship between executive pay and Company performance, including a description of the fulsome process by the Compensation Committee and philosophy that is well aligned with the Company stockholders.

The Board remains firmly committed to maintaining an open and constructive dialogue with our stockholders, and the Compensation Committee will continue to consider stockholder feedback as a critical input in its ongoing evaluation of our executive compensation practices.

***2025 Executive Compensation Highlights***

Based on our overall operating environment and business results, the Compensation Committee approved the following key actions for our NEOs for 2025:

---

| | |
|:---|:---|
| **Pay Element** | **2025 Action** |
| &nbsp;&nbsp;Base Salary | Approved annual base salary increases ranging from 0% to 15% of 2024 base salary. |
| &nbsp;&nbsp;Annual Incentive Plan | Established performance metrics based on achievement of operational, financial and strategic goals, with significant weight (70%) given to annual revenue growth.  |
| &nbsp;&nbsp;Equity Incentive Plan | Granted long-term incentive compensation opportunities in the form of restricted stock awards and performance share awards. The mix of equity grants for NEOs (other than the CEO) is 50% long-term performance share awards (at target) and 50% time-based restricted stock. The mix of equity grants for the CEO is 70% long-term performance share awards (at target) and 30% time-based restricted stock. Performance share awards granted in 2025 have three weighted performance targets: revenue compound annual growth rate, relative total shareholder return and percentage increase in adjusted EBITDA. |

**Compensation Philosophy and Objectives**

Our compensation philosophy is rooted in a pay for performance approach while also considering internal equity and fairness. This approach is designed to strongly link executive officer compensation to our performance. Executive incentive

------

**<u>[**Table of Contents**](#ic2d59f9bf5e7474b9ef29aaf75ccdc2b_7)</u>**

compensation is tied to measurable results intended to create long-term value for our stockholders. Our executive compensation program is designed to promote the following objectives:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• To align the interests of our executives with those of our stockholders who intend to stay invested over a multi-year period;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• To attract, motivate and retain talented executives; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• To compensate executives based upon the value of their individual and collective contributions to achieving corporate goals and objectives.

Our executive compensation program provides for base salaries that reflect the following primary factors: level of responsibility, individual performance, internal fairness and external competitiveness. Additionally, the program provides for both annual incentive awards that are payable upon our achievement of annual financial and management objectives, as well as long-term equity incentives that are intended to align and strengthen the mutuality of interest among management, other key employees and our stockholders.

As shown in the following graphic, the largest component of our compensation plan is dependent on the accomplishment of the Company's financial and functional objectives for a year or more and is directly impacted by market performance of the stock. Based on 2025 summary compensation table (SCT) compensation, 91% of the CEO SCT is variable or "at risk", while 84% of the other named executive officers' SCT is variable.

Below we summarize certain executive compensation program and governance practices – both the practices we have implemented to drive performance and the practices we avoid because we do not believe they would serve our stockholders' long-term interests.

| **What AtriCure Does** | **What AtriCure Does** | **What AtriCure Does** |
| ✓ | **Pays for performance** | A significant portion of executive pay is not guaranteed, but rather is at-risk and tied to the achievement of various performance metrics that are disclosed to stockholders. In addition, a significant portion of CEO and NEO compensation consists of equity incentive awards. The value of equity from these awards is related to the Company's stock price, which aligns with the interests of all stockholders. |
| ✓ | **Sets NEO salary guidelines on an annual basis** | The Company generally considers NEO salaries as part of its annual performance review process in an effort to be responsive to industry trends. |
| ✓ | **Balances short-term and long-term incentives** | The incentive programs provide an appropriate balance of annual and longer-term incentives, with long-term incentive compensation comprising a substantial percentage of target total compensation. |
| ✓ | **Uses multiple performance metrics** | These mitigate the risk of the undue influence of a single metric by utilizing multiple performance measures for annual incentive awards.  |
| ✓ | **Caps award payouts** | Amounts of payments under the annual incentive plan are capped. Amounts or shares that can be earned under our equity plans are capped, both for stock options and for stock awards. |

**Executive Compensation Program and Process**

*Role of the Compensation Committee*

The Compensation Committee oversees and administers our executive compensation policies and plans. The Compensation Committee makes determinations and reports to the Board regarding general recommendations on compensation policies and plans for employees, setting salaries and incentive compensation and approving equity incentive awards for executives. In determining executive compensation, we evaluate a variety of factors relating to the Company's performance as a whole during the year, including financial performance, product development and regulatory and clinical

------

**<u>[**Table of Contents**](#ic2d59f9bf5e7474b9ef29aaf75ccdc2b_7)</u>**

progress. We also review market data and the individual performance of all executives. Our management team supports and makes recommendations to the Compensation Committee in fulfilling its responsibilities and gathers information and performs administrative tasks delegated to it by the Compensation Committee. The Compensation Committee performs the same analysis in connection with determining the compensation of Mr. Carrel, our President and Chief Executive Officer, as it does in determining the compensation of other executive officers. Mr. Carrel does not participate in the discussion and/or approval of his own compensation. We believe that Mr. Carrel's compensation is fair, competitive and consistent with the Company's corporate results and compensation philosophy.

*Compensation Consultants*

The Compensation Committee has the authority to engage the services of outside advisors as necessary to meet its responsibilities. Annually, the Compensation Committee engages the outside service advisors to reevaluate the criteria used to identify and evaluate peer companies.

For 2025 compensation decisions, the Compensation Committee engaged Korn Ferry (KF) as an independent compensation consultant to conduct a competitive pay assessment with respect to the compensation of the Company's executive officers. Before the Compensation Committee engaged KF, it considered the factors identified in NASDAQ Listing Rule 5650(d)(3)(D) in connection with its determination that KF is independent. As part of the executive competitive pay assessment, KF conducted a review of our peer group based on industry, revenue, business life cycle and other pertinent criteria to verify current peers and identify new peers. In order to achieve a robust peer group, the Compensation Committee considered companies with revenues ranging from approximately 0.3X to 3X revenue, with a focus on annual revenue growth and revenue compound annual growth rate (CAGR) performance over three and five year periods. To validate current peers and identify potential new peer companies, KF conducted a screen using both objective and qualitative criteria. The screen addressed the following: (i) company type; (ii) industry classification; (iii) company size (revenue) and (iv) financial and organization characteristics. The Compensation Committee reviewed, discussed and approved the peer group.

The evaluation of 2025 compensation consisted of the following companies:

---

| | | |
|:---|:---|:---|
| Alphatec Holdings, Inc. | Inari Medical, Inc. | Nevro Corp |
| Artivion, Inc. | Inspire Medical Systems, Inc. | Penumbra, Inc. |
| Axogen, Inc. | Insulet Corporation | STAAR Surgical Company |
| Glaukos Corporation | iRhythm Holdings, Inc. | Tactile Systems Technology, Inc. |
| Haemonetics Corporation | LivaNova Plc | Tandem Diabetes Care, Inc. |

---

KF's review of executive compensation covered base salary, target short-term incentives, total target cash compensation, long-term incentives and total target direct compensation. Based on KF's review and analysis, peer group benchmarking, NEO performance and input, as well as other factors, the Compensation Committee implemented the compensation adjustments described in this Compensation Discussion and Analysis section and the other compensation related discussion included in this proxy statement.

In addition to peer compensation data, we review life sciences and general industry survey data for assessing pay competitiveness relative to market. Market data is used as a reference point for understanding the external market for these positions. The goal in using market data is to strike a balance between external competitiveness and internal equity and to align pay to the Company's compensation philosophy.

*Elements of Executive Compensation*

Compensation to our executive officers generally consists of the following elements:

---

| | | | | |
|:---|:---|:---|:---|:---|
| &nbsp;&nbsp;**Element** | &nbsp;&nbsp;**Philosophy Objective** | &nbsp;&nbsp;**Form** | &nbsp;&nbsp;**Type** | &nbsp;&nbsp;**Performance Criteria** |
| &nbsp;&nbsp;Base Salary | &nbsp;&nbsp;To attract, motivate and retain talented executives | &nbsp;&nbsp;Cash | &nbsp;&nbsp;Fixed | &nbsp;&nbsp;Continued service |
| &nbsp;&nbsp;Annual incentive bonus | &nbsp;&nbsp;To compensate executives based upon the value of their individual and collective contributions to achieving corporate goals and objectives | &nbsp;&nbsp;Cash | &nbsp;&nbsp;Variable | &nbsp;&nbsp;Pre-established performance metrics based on achievement of operational, financial and strategic goals |
| &nbsp;&nbsp;Equity incentive awards | &nbsp;&nbsp;To align the interests of our executives with those of our stockholders who intend to stay invested over a multi-year period | Restricted stock awards<br>Performance share awards | &nbsp;&nbsp;Variable | &nbsp;&nbsp;The realizable value of restricted stock awards is linked to the Company's stock price after the grant date. Performance share awards are not earned unless specific levels of Company performance are achieved. Vesting periods are three years for restricted stock awards and performance share awards. |

---

In addition, our executive officers generally receive the same health and welfare benefits package available to all of our employees. We believe this mix of cash and equity compensation and short and long-term compensation afforded to all of our executives is consistent with our compensation philosophy and furthers our overall compensation objectives by encouraging short and long-term performance and creating an effective management team which can lead our growth and expansion and maximize stockholder value.

The Compensation Committee has reviewed the risk profile of the various elements of our executive compensation program, including the performance objectives and target levels used in connection with incentive awards, and has considered the risks our executive officers might be incentivized to take with respect to such elements. When establishing the mix among these elements, the Compensation Committee is careful not to encourage excessive risk taking and, as a result, the Compensation Committee believes that our executive compensation program does not incentivize the executive officers to engage in business activities or other behavior that would threaten the value of the Company or the investments of its stockholders.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**1. *Base Salary*.** In determining base salaries, we consider a variety of factors, including the officer's job scope and level of responsibility, as well as individual factors such as experience, skills and performance. We also consider market data relating to compensation for similar positions at other medical device and life science companies and competitive factors in the industry. In addition, we consider relative levels of pay among our officers and recommendations from the Chief Executive Officer. Salary levels are generally considered annually as part of our annual performance review process, as well as upon a promotion or other change in job responsibility. Salary guidelines are set each year to reflect our industry's competitive environment, balanced by the desire to control the overall cost of salaries and wages, as well as consistency with our annual employee merit increase guidelines.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**2. *Annual Incentive Plan*.** We pay annual incentives to management which vary in size depending on the level of achievement of specific operational, financial and strategic goals considered by the Board to be critical in building long-term value for stockholders. Annual incentives earned during 2025 were paid in cash. In future years, annual incentives may be paid in cash, through equity awards or through a combination of both.

For executive officers, annual incentive targets and objectives are designed to advance key strategic initiatives and build stockholder value and, therefore, primarily relate to the achievement of company-wide revenue and functional goals. We believe that company-wide goals help to foster effective cross-functional performance and a culture of collaboration. Annual objectives and targets are developed with guidance from management and approved by the Compensation Committee. Levels of performance are measured and communicated by management to the Compensation Committee and Board of Directors on a regular basis.

The Compensation Committee set target objectives that the Committee deemed challenging to attain. The determination of the annual incentive targets was based on financial and functional measures. The Compensation Committee used constant currency revenue growth to measure financial performance because it believed revenue growth is highly linked to creating both short and long-term value to stockholders. The Company provides annual revenue guidance which aligns with the short-term nature of the revenue metric used within the annual incentive plan and selected a constant currency metric in the 2025 annual incentive plan to better measure the comparability of results between periods given the growth in the Company's international business. The Compensation Committee also used functional objectives, or "pillar objectives", related to innovation, clinical science, education & adoption, and people, because it understands these objectives were directly linked to creating long-term value for stockholders. The Compensation Committee was diligent in setting the pillar objectives, as well as the weighting and threshold, target and maximum performance objectives with the intent of establishing a mix ranging from attainable to very difficult to achieve (e.g. those goals which include elements of the goal which are outside of the Company's control, such as regulatory approvals). Additionally for 2025, a profitability bonus was added to the annual incentive plan whereby if the Company exceeded its target Adjusted EBITDA goal, an additional 10 percentage points would be added to the final attainment of the annual incentive plan. This profitability bonus was designed to be one-time in nature as the Company and Committee anticipated incorporating Adjusted EBITDA (or profitability) goals as component of the annual incentive plan in 2026 and beyond.

Pillar & People objectives include the following; any additional disclosure of specific plan targets has not been shared, as doing so could result in competitive harm to the Company.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;a.three Innovation goals including multiple product development milestones, such as the first-in-human treatment using Pulsed Field Ablation (PFA), initiating both design verification builds and reliability testing for the next-generation cryo generator, and completion of User Preference Evaluation (UPE) for the cryoXT<sup>®</sup> probe, and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;b.two Clinical Science goals related to clinical trial enrollment and site initiation, including completing LeAAPS clinical trial enrollment and site initiation for the BoxX-NoAF clinical trial, and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;c.three Education & Adoption goals that involve increased product adoption, retention and growth of customer accounts, including account growth for EnCompass<sup>®</sup>, EPi-Sense<sup>®</sup> and AtriClip<sup>®</sup> FLEX-Mini™, and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;d.one People goal for retaining talent better than industry standards and continued progress on diversity initiatives.

For the named executive officers, the base salary and target annual incentive were determined in accordance with the Company's executive compensation philosophy and objectives described above, and as part of the Chief Executive Officer's annual compensation and performance review. Performance between goals is linearly interpolated. The Compensation Committee approved a 2025 incentive program that would have enabled these executive officers to earn the target and maximum incentives set forth below as a percentage of their base salaries.

(1)Pillar & People objectives include the following (a) three Innovation goals including multiple product clearances and development milestones, (b) two Clinical Science goals related to specific enrollment levels for our clinical trial enrollment and site initiation, (c) three Education & Adoption goals that involve increased product adoption, retention and growth of customer accounts, and (d) one People goal for attracting and retaining diverse talent.

(2)The total value of the Profitability Goal was 10% points added to the annual incentive plan if achieved, and measured Adjusted EBITDA ***after*** the impact of the additional bonus expense of achieving this goal.

The 2025 annual incentive plan's monetary increase in worldwide revenue at the threshold for entry remained consistent at $56 million, although the percentage growth rate has declined reflecting a higher revenue base that is naturally moderating growth rates over time. A profitability goal (adjusted EBITDA) was included in 2025 to add focus on improving operating leverage of the Company. The profitability goal's threshold was a monetary increase of $14 million or 45% growth over actual 2024 Adjusted EBITDA of $31 million. Altogether, these changes reflect maturation of the Company's operating model, additional focus on improving profitability, and new entrants developing competing products, procedures, and/or clinical solutions that cause variability in our results.

As shown above, our results for both worldwide revenue growth and pillar and people objectives achieved between the target and the maximum thresholds, and the one-time profitability goal was achieved, resulting in 134.7% achievement of the annual incentive plan based on the design above.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**3. *Equity Incentive Awards*.** We issue equity awards to our executive officers and employees under our equity plans to create an opportunity for our executive officers and employees to acquire an equity ownership interest in the Company and thereby motivate and retain executive talent and align employees and executives with the long-term interests of stockholders. Share-based awards are intended to reflect the participant's position, responsibility, contributions and performance and to consider market data and each individual's current equity position. We believe that share-based awards will stimulate pride in ownership and motivate employees and executives to commit themselves to our performance and increasing stockholder value.

The Compensation Committee continually reviews the value and mix of equity awards granted to executive officers in light of equity awards at peer group companies. The Compensation Committee also considers wealth accumulation for executive officers as a factor in making additional equity awards both as to type of award and number of underlying shares. The mix of equity grants for NEOs (other than the CEO) is 50% long-term performance share awards and 50% time-based restricted stock, while the mix of equity grants for the CEO is 70% long-term performance share awards and 30% time-based restricted stock.

PSAs granted in 2025 have three weighted performance targets measured over a three-year performance period: (i) the Company's revenue CAGR in constant currency, a performance condition, (ii) Adjusted EBITDA goal, a performance condition, and (iii) relative total shareholder return (TSR), a market condition. The 2025 PSAs are weighted 50% on the CAGR performance target, 30% on the Adjusted EBITDA target, and 20% on the TSR performance target, with specific goals shown in the following table.

The performance and market condition payouts will be determined independently and accumulated to determine the total payout for the three-year performance period, subject to the maximum payout defined in the PSA agreements. The allocation of the number of shares for the performance share grant is calculated based on the closing stock price on the date of grant and weighted between the performance targets. However, the fair value is calculated independently:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The fair value of the restricted stock awards and performance share awards with the revenue CAGR and Adjusted EBITDA performance conditions are measured based on the market value of the Company's stock on the date of grant of the awards or subsequent modification (if applicable). The grant date fair value of the 2025 awards was $38.74 for awards granted on March 1, 2025. While the Company utilizes revenue growth and Adjusted EBITDA in both the annual incentive and long-term incentive plans, the long-term incentive plan metrics are set at the beginning of three-year forward-looking period and consider the progress over this multi-year period when measured. As a result, the threshold levels differ as the longer performance period reflects a compounding base impact, which naturally moderates percentage growth rates over time.

**<u>[**Table of Contents**](#ic2d59f9bf5e7474b9ef29aaf75ccdc2b_7)</u>**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The fair value of performance share awards with the TSR market condition is estimated on the grant date using a Monte Carlo simulation. Determination of the fair value is affected by the Company and NASDAQ Health Care Index constituents, as defined by the award agreement, at the beginning of the service period and grant date, the expected volatility of the Company and NASDAQ Health Care Index constituents' stock price over the performance period and the correlation coefficient of the daily returns for the Company and NASDAQ Health Care Index constituents over the performance period. The grant date fair value of the 2025 performance share awards with the TSR market condition was $68.69 for awards granted on March 1, 2025.

The disparity in the fair value of the revenue CAGR and Adjusted EBITDA performance conditions and TSR market condition portions of the performance share awards is driven by the inputs utilized in the measurement of the TSR performance shares. Specifically, the coefficient of correlation of the daily returns for the Company and NASDAQ Health Care Index constituents stock price over the performance period demonstrated that AtriCure's common stock is expected to outperform the NASDAQ Health Care Index constituents based on historical activity, causing a greater estimated fair market value on the date of grant. The higher fair value of performance share awards with the TSR market condition, approximately 77% greater than the fair value of performance share awards with the revenue CAGR and Adjusted EBITDA performance conditions based on the market value of the Company's stock on the date of grant, is the driver of the difference between the long-term incentive value award by the Compensation Committee and the grant date fair market value of the award. In 2025, the Compensation Committee granted our NEOs long term incentive performance share awards valued at a target of $8,600,000 in total, which resulted in $9,929,613 in grant date fair market value, with the increase due to the fair value of the performance share awards with the TSR market condition, estimated using a Monte Carlo simulation as described above.

(1)The allocation of the number of shares for the 2025 performance share award grant is calculated based on long-term incentive value divided by the closing stock price on date of grant.

(2)In accordance with FASB ASC 718, the fair value of the restricted stock awards and performance share awards with the revenue at constant currency CAGR and Adjusted EBITDA performance conditions are measured based on the market value of the Company's stock on the date of grant of the awards. The fair value of performance share awards with the TSR market condition is estimated on the grant date using a Monte Carlo simulation. For 2025 grants, the fair value of restricted stock awards and performance share awards with revenue CAGR and Adjusted EBITDA performance conditions was $38.74, while fair value of performance share awards with the TSR market condition was $68.69.

PSAs awarded prior to 2025 have two weighted performance targets measured over a three-year performance period: (i) the Company's revenue CAGR, a performance condition and (ii) relative TSR, a market condition. PSAs granted in 2023 and 2024 are weighted 75% on the CAGR performance target and 25% on the TSR performance target and have payout opportunities ranging from 0% to 300% of the target amount. PSAs vest at the end of the performance period, as defined by the PSA agreement. The performance share awards granted in 2023 fully vested on December 31, 2025 at 94% attainment of the combined revenue CAGR and TSR performance targets.

The Compensation Committee recognizes that both the annual incentive plan and the long-term performance share awards utilize the Company's worldwide revenue growth as a performance metric. The Compensation Committee believes that at this time it is appropriate for the Company to utilize worldwide revenue growth as a performance metric for both the annual incentive plan and the long-term performance share awards due to the importance of this metric to the Company's investors. The Company believes that many of its current and prospective investors view worldwide revenue growth as the single most important performance metric of the Company. The annual incentive plan is measured over a one-year performance period, while the 2025 performance share awards are measured over a three-year performance period. As a result, the threshold levels differ as the longer performance period reflects a compounding base impact, which naturally moderates percentage growth rates over time. The Company also regularly engages with investors regarding the performance metrics that are most important. Based on this engagement, the long-term performance share awards have included total shareholder return (TSR) as a market metric since 2021 and added a profitability metric (Adjusted EBITDA) beginning in 2025.

Each year, the Compensation Committee considers grants for executive officers and employees based on recommendations from the CEO, as well as the factors described above. With respect to newly hired or promoted executives, the size of the initial equity grants is determined based on the individual's position, experience and competitive market information. New hire or promotion grants are generally made at the date of hire or promotion. The exercise price for options (if granted) equals the fair market value of our common stock on the date of the grant. In response to Item 402(x)(1) of Regulation S-K, we do not grant new awards of stock options, stock appreciation rights or similar option-like instruments in anticipation of material nonpublic information. Accordingly, we have no specific policy or practice on the timing of awards of such options in relation to the disclosure of material nonpublic information by us. In the event we determine to grant new awards of such options the Board will evaluate the appropriate steps to take in relation to the foregoing.

***Recovery of Prior Incentive Compensation***

Under the Company's Incentive Compensation Recoupment Policy (Clawback Policy), if the Company is required to prepare an accounting restatement (Restatement), the Board shall take reasonably prompt action to recoup all erroneously awarded compensation that would not have been received had the amount been determined based on the measures in the Restatement. The Board may seek to recoup the erroneously awarded compensation by any means as the Board, in its sole discretion, determines to be appropriate. The Board may also determine whether, and to what extent, additional action is appropriate to address the circumstances surrounding any Restatement to reduce the risk of recurrence and to impose such other discipline as the Board deems fit. This Clawback Policy is in addition to (and not in lieu of) any right of repayment, forfeiture or off-set against any person that may be available under law or otherwise. The Board has delegated to the Compensation Committee its powers to administer the Clawback Policy.

AtriCure's 2023 Stock Incentive Plan provides that any award issued under it shall be subject to forfeiture or repayment pursuant to the terms of any applicable compensation recoupment or recovery policy adopted by the Company, Compensation Committee or Board, as thereafter amended, including any policy adopted to comply with the rules of NASDAQ or the SEC. As a result, time-based and performance-based awards issued pursuant to our equity plans are subject to the Clawback Policy.

***Perquisites***

We do not generally provide executives with perquisites other than programs made available to all Company employees. Mr. Seith receives an annual car allowance of $7,200, consistent with the car allowances provided to other AtriCure field-based personnel. The Compensation Committee adopted a policy that states that NEOs of the Company will not be reimbursed by the Company for personal taxes owed by them resulting from their receipt of perquisites, other than for relocation expenses.

(1)Amounts in the stock awards column represent the aggregate grant date fair value of restricted stock (RSA), performance share awards (PSA) (valued assuming target performance) and performance share units (PSUs) granted pursuant to the 2023 Stock Incentive Plan. The aggregate grant date fair value of the awards is calculated by the number of shares of Common Stock underlying the RSAs, PSAs (at target) and PSUs (at target) by the estimated fair value in accordance FASB ASC Topic 718. The fair value of RSAs and PSAs with revenue CAGR and Adjusted EBITDA performance conditions are measured based on the market value of the Company's stock on the date of grant of the awards. The fair value of PSAs with a TSR market condition and PSUs with a market condition is estimated on the grant date using a Monte Carlo simulation. RSAs, PSAs and PSUs awarded for 2024 performance were granted in 2025; these awards are reflected in 2025 compensation. RSAs and PSAs awarded for 2023 performance were granted in 2024; these awards are reflected in 2024 compensation. RSAs and PSAs awarded for 2022 performance were granted in 2023; these awards are reflected in 2023 compensation. The aggregate fair value of PSAs and PSUs granted in 2025 for 2024 performance, assuming achievement at target performance levels, was as follows:

Actual awards earned and paid to the named executive officers under these plans are reported in the Non-Equity Incentive Plan Compensation column in the Summary Compensation Table and are discussed earlier under the heading "Compensation Discussion and Analysis".

(2)Awards granted under the 2023 Stock Incentive Plan.

(3)In accordance with FASB ASC 718, the fair value of RSAs and PSAs with revenue CAGR and Adjusted EBITDA performance conditions are measured based on the market value of the Company's stock on the grant date of the awards. The fair value of PSAs with a TSR market condition is estimated on the grant date using a Monte Carlo simulation. Fair value of RSAs and PSAs with revenue CAGR and Adjusted EBITDA performance conditions were $38.74, while the fair value of PSAs with a TSR market condition was $68.69.

(1)Based on the December 31, 2025 closing price of our common stock of $39.56 per share.

(2)Restricted stock awards granted vest in one-third increments on the first, second and third anniversaries of grant.

(3)Performance share awards vest on the three-year anniversary of the award date, subject to achievement of specified performance measurements. The performance share awards in this table reflect the 94% attainment approved for the 2023 awards and the target amount of shares that were granted in 2024 and 2025.

(4)In 2024, the Compensation Committee approved a special grant of Performance Share Units (PSUs) to Mr. Carrel, in addition to his regular equity grant. The PSUs vest based on the attainment of specified stock prices over three measurement periods over a four-year period. PSUs vest in five defined tranches on the last day of three specified measurement periods, subject to a market vesting condition upon the simple moving average of the closing share price during the 60 consecutive calendar days immediately prior to and including the measurement period date. The PSU share price targets range from $50.00 to $100.00 and the underlying shares for each measurement period range from 16,538 shares to 41,345 shares. The maximum number of shares attainable is 165,380 shares. As the first measurement period ends in 2026 and in the preceding fiscal year the closing share price, as of December 31, 2025, was less than the minimum performance criteria, the market value of the PSU awards has been presented as $0.

**Severance and Change in Control Arrangements**

We have an employment agreement with Michael H. Carrel, our President and Chief Executive Officer. We also have Change in Control Agreements and Severance Agreements with Ms. Wirick, our Chief Financial Officer; Mr. Seith, our Chief Operating Officer; Mr. Privitera, our Chief Technical Officer, and Mr. Noznesky, our Chief Marketing and Strategy Officer.

***Carrel Employment Agreement***

If the Company terminates Mr. Carrel's employment "without cause" or if he terminates his employment for "good reason," each as defined in the employment agreement, Mr. Carrel is entitled to a severance payment equal to twelve months of his then-current base salary plus a pro-rata portion of his target bonus for the year in which such termination occurred through the date of termination. If the termination occurs during a change in control period, he is entitled to a severance payment equal to up to twenty-four months of his then-current base salary plus his target bonus for the severance period. In the case of termination by Mr. Carrel for "good reason" or by the Company "without cause" or in the case of any change of control, any unvested restricted shares or time-based stock options shall fully vest on the date of termination.

***Other Named Executive Officers' Severance Agreements***

The Company has an Executive Leadership Severance Policy ("Severance Policy") which provides payments to eligible executive officers of the Company (other than the CEO) whose employment is involuntarily terminated in certain circumstances not involving a change in control. Under the Severance Policy an executive officer who experiences an involuntary loss of employment with the Company as a direct result of position elimination or reduction in force not involving a change in control of the Company will be eligible for severance pay. The severance pay under the Severance Policy is equal to one and one-half times the executive officer's base salary and shall be made in the form of the continuation of the payment over the eighteen months after termination of employment in accordance with the Company's payroll practices in effect. This description of the Severance Policy is not complete. The Severance Policy is filed with the Company's 2021 Annual Report on Form 10-K as Exhibit 10.20.

***Other Named Executive Officers' Change in Control Agreements***

Each of the NEO's have separate change in control agreements. Mr. Seith's and Ms. Wirick's change in control agreements provide that if his or her employment terminates during a change in control period other than in connection with death, disability, "cause" or "good reason," (each as defined in such agreement), he or she is entitled to a severance payment equal to twenty-four months of his or her then-current base salary plus target bonus for the severance period. Mr. Privitera's and Mr. Noznesky's change in control agreements provide that if his employment terminates during a change in control period other than in connection with death, disability, "cause" or "good reason," (each as defined in such agreement), he is entitled to a severance payment equal to eighteen months of his then-current base salary plus his target bonus for the severance period.

**<u>[**Table of Contents**](#ic2d59f9bf5e7474b9ef29aaf75ccdc2b_7)</u>**

***Treatment of Equity Awards***

After termination of an executive officer or director following a change in control, any full-value awards become fully vested and all performance goals or other vesting criteria will be deemed achieved at target levels pursuant to the terms of our 2005 Equity Incentive Plan, 2014 Stock Incentive Plan or our 2023 Stock Incentive Plan and/or the related award agreement. All outstanding options vest and become fully exercisable pursuant to the terms of our 2023 Stock Incentive Plan and/or the related stock option agreements. Generally, if termination is due to death or disability, the options will remain exercisable for twelve months. In all other cases or termination, including retirement, the options will generally remain exercisable for 90 days.

The table below shows the potential payments, other than those generally available to all salaried employees, which would be payable to each named executive officer assuming a qualifying change in control or other triggering event had occurred on December 31, 2025.

(1)Other includes medical, dental, life insurance or similar "welfare" benefits substantially similar in scope and cost available immediately prior to the Change in Control Period.

**Indemnification Agreements**

In addition to the Company's director and officer liability insurance program, the Company has entered into indemnification agreements with each of its directors and executive officers to give such directors and officers additional contractual assurances regarding the scope of the indemnification set forth in the Company's Restated Certificate of Incorporation and to provide additional procedural protections. The Agreements require the Company to indemnify the individuals to the fullest extent authorized by the Company's charter document and provides for the advancement of expenses. The Company intends to enter into indemnification agreements with any new directors and executive officers in the future. The Form of Indemnity Agreement with Directors and Executive Officers is filed with the Company's 2024 Annual Report on Form 10-K as Exhibit 10.18.

**Pay Ratio Disclosure**

As required by Section 953(b) of the Dodd-Frank Act and Item 402(u) of Regulation S-K, we are providing disclosure of the ratio of the median employee's annual total compensation to that of the principal executive officer ("PEO"). Consistent with the disclosure instructions of Item 402(u) of Regulation S-K, the applicable SEC rule, we may identify our median employee for purposes of providing pay ratio disclosure once every three years and calculate and disclose total compensation for that employee each year; provided that during the last completed fiscal year, there has been no change in the employee population or employee compensation arrangements that we reasonably believe would result in a significant change. Under the SEC's rules and guidance, there are numerous ways to determine the compensation of a company's median employee, including the employee population sampled, the elements of pay and benefits used, any assumptions made and the use of statistical sampling. In addition, no two companies have identical employee populations or compensation programs, and pay, benefits and retirement plans may differ by country even within the same company. As such, our pay ratio may not be comparable to the pay ratio reported by other companies.

A new median employee was identified in 2023 due to the three-year timeframe noted by the disclosure instructions of Item 402(u). We reviewed changes in our employee population and employee compensatory arrangements and determined there has been no change in our employee population or employee compensatory arrangements that would significantly impact the 2025 pay ratio disclosure. Our total number of full-time employees as of December 31, 2025 was 1,346 individuals – 1,212 in the United States and 134 outside of the United States. Pursuant to the *de minimis* exemption for foreign employees as permitted by applicable SEC rules, we excluded 55 employees from the following 12 countries:

------

**<u>[**Table of Contents**](#ic2d59f9bf5e7474b9ef29aaf75ccdc2b_7)</u>**

Australia, Austria, Belgium, Canada, China, France, Italy, Japan, Norway, Singapore, Spain and Taiwan. The calculation of the median employee's income was prepared using a listing of employees with their corresponding annual total cash compensation (base salary or hourly wages, overtime wages, and bonuses) and equity grants, based on the Company's payroll and other compensation records. For those employees that were not employed for the full fiscal year, their salary and variable compensation were annualized to compute their total compensation. Wages paid in foreign currencies were converted into U.S. dollars using the applicable year-to-date average exchange rates as of December 31, 2025.

The Company's PEO is Mr. Carrel, our President and Chief Executive Officer. Mr. Carrel's annual total compensation for 2025, as noted in the Summary Compensation Table above, was $9,217,620. The median employee's (excluding the PEO) annual total compensation for 2025 was $144,309. Therefore, we reasonably estimate that the ratio of our PEO's annual total compensation to the annual total compensation of our median employee was 64:1, as compared to the 2024 ratio of 83:1. The fluctuation in the pay ratio is primarily due to the special equity grant of performance share units granted to the PEO during 2024.

**Pay Versus Performance** 

As required by Section 953(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 402(v) of Regulation S-K, we are providing disclosures of the relationship between executive compensation paid and the Company's financial performance. Under the SEC's pay versus performance rules, the SEC has developed a new definition of pay, referred to as Compensation Actually Paid ("CAP"), which is compared to certain performance measures defined by the SEC.

In the table below, totals for the Summary Compensation Table ("SCT") and CAP values represent a mix of both compensation earned during the year (base salary and annual incentives) and estimated future pay opportunities (equity incentive awards). The difference between the SCT presentation and calculation of CAP is the value attributable to equity incentive awards. Within SCT values, equity incentive awards include the grant date fair value of equity incentive awards awarded during the year, reflecting the evaluation of the prior year's performance. Within CAP values, equity incentive awards represents the year-over-year change in the values of unvested equity incentive awards, awards that vested or forfeited during the year, as well as the year-end valuation of equity incentive awards granted during the year.

| Shareholder Return |

---

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Worldwide revenue growth is calculated as the percentage change in worldwide revenue over the prior year. Worldwide revenue growth impacts both the achievement of our annual incentive plan objectives and performance targets of equity incentive awards.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Shareholder return is calculated as the percentage change in stock price as of December 31 year over year. Shareholder return impacts the achievement of performance targets of equity incentive awards, as well as the value of stock awards realized by our named executive officers.

*Analysis of Information Presented in the Pay versus Performance Table*

Our compensation philosophy is to strongly link executive officer compensation to our performance and is intended to create long-term value for our stockholders. In accordance with Item 402(v) of Regulation S-K, we are providing the following description of relationships between information presented in the Pay versus Performance Table.

*Cumulative TSR*

The chart below reflects the relationship between the compensation actually paid to the PEO and average compensation actually paid to the Non-PEO NEOs to AtriCure's TSR and the peer group TSR.

![5983](atrc-20260403_g4.jpg)

The Company's chosen peer group is the NASDAQ Heath Care Index constituents. This is the same peer group disclosed in the Form 10-K performance graph, as well as the same index used to measure the relative total shareholder return performance target for the performance share awards granted annually to our executive officers since 2021. Over the five-year period shown in the table above, the Company's total shareholder return (TSR) was similar to the peer group's

TSR. The Company's stock performance significantly impacts executive compensation as approximately 70% or greater of the PEO total compensation and over 50% of the non-PEO total compensation is comprised of equity incentive plan awards since 2021. Therefore, CAP for the PEO and non-PEO NEOs is positively correlated to fluctuations in the Company's stock performance as it has a significant impact on the valuation of the underlying equity incentive awards included in the calculation of CAP. The percentage change in the Company TSR from the grant date and year over year has a proportionate impact on the CAP paid.

Our strategy is to make investments to drive sustainable growth, and we incur substantial expenditures to develop and commercialize our products, expand our markets and build a foundation to support future growth. As a result, we have incurred net losses throughout our history. Our net losses have resulted principally from costs and expenses relating to sales, training and awareness efforts, research and product development, clinical trials, seeking regulatory clearances and approvals, product quality and safety initiatives and general operating expenses. Our net income (loss) can also be significantly impacted by non-recurring adjustments or charges that are not reflective of our ongoing core business operations and financial condition, as was the case in fiscal year 2021. We believe net income (loss) is not reflective of our ongoing core operations of our business, nor is it a metric that is most important to stockholder value. Therefore, it is not a metric used in any of the Company's incentive plans, and CAP is not correlated with net income (loss).

Worldwide revenue growth is the most important company-selected measure. The Compensation Committee believes at this time it is appropriate for the Company to utilize worldwide revenue growth as a performance metric for both the annual incentive plan and the long-term performance share awards due to the importance of this metric to the Company's investors. The Company believes that many of its current and prospective investors view worldwide revenue growth as the single most important performance metric of the Company. Annual revenue growth is used as a metric for performance attainment of the annual incentive plan, while revenue CAGR over a three-year performance period is used for the performance share awards included in the long-term equity incentive plans. Due to the difference in performance period duration, as well as the significant impact of the Company's stock price on the valuation of the equity incentive awards included in the calculation of CAP, the CAP for the PEO and non-PEO NEO is not correlated in the periods presented. Non-PEO NEO CAP was also impacted by the shifting of non-PEO membership within the periods presented.

**DELINQUENT SECTION 16(a) REPORTS**

Section 16(a) of the Exchange Act requires our directors, executive officers and beneficial owners of more than 10% of our common stock to file with the SEC reports regarding their ownership and changes in ownership of our common stock. Such persons are required by SEC regulations to furnish us with copies of all Section 16(a) forms they file.

Based solely on our examination of the copies of such forms received by us, or written representations from reporting persons that no Forms 3, 4 or 5 were required of such persons, we believe that during our fiscal year ended December 31, 2025, our directors, executive officers and 10% stockholders complied with all Section 16(a) filing requirements.

This Plan document is an omnibus document which authorizes, in addition to the Plan, the establishment of separate sub-plans ("<u>Sub Plans</u>") that the Committee (defined below) may create and administer from time to time. The Plan shall be a separate and independent plan from the Sub Plans, but the total number of shares of Common Stock authorized to be issued under the Plan applies in the aggregate to both the Plan and the Sub Plans.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;b.Subject to the provisions of the Plan and applicable law, the Committee shall have the sole and plenary authority, in addition to other express powers and authorizations conferred on the Committee by the Plan, to: (i) designate Participants; (ii) determine the type or types of Awards to be granted to a Participant; (iii) determine the number of shares of Common Stock to be covered by, or with respect to which payments, rights, or other matters are to be calculated in connection with, Awards; (iv) determine the terms and conditions of any Award, including the vesting provisions; (v) determine whether, to what extent, and under what circumstances Awards may be settled or exercised in cash, shares of Common Stock, other securities, other Awards or other property, or canceled, forfeited, or suspended and the method or methods by which Awards may be settled, exercised, canceled, forfeited, or suspended; (vi) determine whether, to what extent, and under what circumstances the delivery of cash, Common Stock, other securities, other Awards or other property and other amounts payable with respect to an Award shall be deferred either automatically or at the election of the Participant or of the Committee; (vii) establish any Sub Plans that may be governed by the Plan; (viii) interpret, administer, reconcile any inconsistency in, correct any defect in and/or supply any omission in the Plan and any instrument or agreement relating to, or Award granted under, the Plan; (ix) establish, amend, suspend, or waive any rules and regulations and appoint such agents as the Committee shall deem appropriate for the proper administration of the Plan; (x) accelerate the vesting or exercisability of, payment for or lapse of restrictions on, Awards (including previously deferred Awards), and accelerate and determine payouts, if any, in respect of Awards with incomplete Performance Periods, in each case upon a Change in Control, death, Disability or Retirement (or on any other termination of employment) of a Participant; and (xi) make any other determination and take any other action that the Committee deems necessary or desirable for the administration of the Plan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;c.Except to the extent prohibited by applicable law or the applicable rules and regulations of any securities exchange or inter-dealer quotation system on which the securities of the Company are listed or traded, the Committee may allocate all or any portion of its responsibilities and powers to any one or more of its members and may delegate all or any part of its responsibilities and powers to any person or persons selected by it. Any such allocation or delegation may be revoked by the Committee at any time. Without limiting the generality of the foregoing, the Committee may delegate to one or more officers of the Company the authority to act on behalf of the Committee with respect to any matter, right, obligation, or election that is the responsibility of or that is allocated to the Committee herein, and that may be so delegated as a matter of law, except for grants of Awards to persons subject to Section 16 of the Exchange Act. When the Committee delegates its authority hereunder to one or more officers of the Company, it shall specify the total number of Awards that the officer or officers may award and the terms on which any Awards may be offered or sold. In no event shall the Committee authorize any officer to designate such officer as a recipient of any Awards.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;d.Unless otherwise expressly provided in the Plan, all designations, determinations, interpretations, and other decisions under or with respect to the Plan or any Award or any documents evidencing Awards granted pursuant to the Plan shall be within the sole discretion of the Committee, may be made at any time and shall be final, conclusive and binding upon all persons or entities, including, without limitation, the Company, any Affiliate, any Participant, any holder or beneficiary of any Award, and any stockholder of the Company.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;e.No member of the Board, the Committee or any employee or agent of the Company (each such person, an "<u>Indemnifiable Person</u>") shall be liable for any action taken or omitted to be taken or any determination made with respect to the Plan or any Award hereunder (unless constituting bad faith, fraud or a willful criminal act or omission). Each Indemnifiable Person shall be indemnified and held harmless by the Company against and from any loss, cost, liability, or expense (including attorneys' fees) that may be imposed upon or incurred by such Indemnifiable Person in connection with or resulting from any action, suit or proceeding to which such Indemnifiable Person may be a party or in which such Indemnifiable Person may be involved by reason of any

**<u>ANNEX A</u>**

action taken or omitted to be taken or determination made under the Plan or any Award Agreement and against and from any and all amounts paid by such Indemnifiable Person with the Company's approval, in settlement thereof, or paid by such Indemnifiable Person in satisfaction of any judgment in any such action, suit or proceeding against such Indemnifiable Person, provided that the Company shall have the right, at its own expense, to assume and defend any such action, suit or proceeding and once the Company gives notice of its intent to assume the defense, the Company shall have sole control over such defense with counsel of the Company's choice. The foregoing right of indemnification shall not be available to an Indemnifiable Person to the extent that a final judgment or other final adjudication (in either case not subject to further appeal) binding upon such Indemnifiable Person determines that the acts or omissions or determinations of such Indemnifiable Person giving rise to the indemnification claim resulted from such Indemnifiable Person's bad faith, fraud or willful criminal act or omission or that such right of indemnification is otherwise prohibited by law or by the Company's Amended Articles of Incorporation or Amended and Restated Code of Regulations. The foregoing right of indemnification shall not be exclusive of any other rights of indemnification to which such Indemnifiable Persons may be entitled under the Company's Amended Articles of Incorporation or Amended and Restated Code of Regulations, as a matter of law, or otherwise, or any other power that the Company may have to indemnify such Indemnifiable Persons or hold them harmless.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;f.Notwithstanding anything to the contrary contained in the Plan, the Board may, in its sole discretion, at any time and from time to time, grant Awards and administer the Plan with respect to such Awards. In any such case, the Board shall have all the authority granted to the Committee under the Plan.

**5. <u>Grant of Awards; Shares Subject to the Plan; Limitations.</u>** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;a.The Committee may, from time to time, grant Options, Stock Appreciation Rights, Restricted Stock, Restricted Stock Units, Other Stock-Based Awards and/or Performance Compensation Awards to one or more Eligible Persons.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;b.Awards granted under the Plan shall be subject to the following limitations: (i) subject to Sections 5(c) and 12 of the Plan, no more than the sum of (A) 6,000,000 4,500,000 shares of Common Stock plus (B) the number of shares of Common Stock that, as of the Effective Date, are remaining available for issuance or delivery, and not subject to outstanding awards, under the Prior Plan may be delivered in the aggregate pursuant to Awards granted under the Plan (such sum of (A) and (B), the "<u>Effective Date Share Limit</u>"); (ii) subject to Section 12 of the Plan, no more than the number of shares of Common Stock equal to the Effective Date Share Limit may be delivered in the aggregate pursuant to the exercise of Incentive Stock Options granted under the Plan; and (iii) the maximum number of shares subject to Awards granted to any Non-Employee Director during a single fiscal year shall be limited so that the Awards, taken together with any cash fees paid to such Non-Employee Director in respect of his or her service during such year (including service as a member or chair of any committees of the Board), do not exceed $1,000,000 in total value (calculating the value of any such Awards based on the grant date fair value of such Awards for financial reporting purposes). Notwithstanding the foregoing, the Board may make exceptions to the limit in the foregoing clause (iii) for (A) a non-executive chairman of the Board, provided that such non-executive chairman does not participate in the decision to award such compensation, and (B) special projects and ad hoc committee appointments, as deemed appropriate by the Board, from time to time.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;c.The following rules shall apply in determining the number of shares of Common Stock available for grant under the Plan:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;i.Shares of Common Stock subject to any Award shall be counted against the Effective Date Share Limit as one share of Common Stock for every share of Common Stock subject to such Award.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;ii.To the extent that any Award is forfeited, cancelled, settled in cash, returned to the Company for failure to satisfy vesting requirements or other conditions of the Award or otherwise terminates without an issuance of shares of Common Stock being made, the Effective Date Share Limit shall be credited with one share of Common Stock for each share of Common Stock subject to such Award, and such number of credited shares of Common Stock may again be made subject to Awards under the Plan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;iii.Any shares of Common Stock tendered by a Participant or withheld as full or partial payment of withholding or other taxes or as payment for the exercise or conversion price of an Award or repurchased by the Company with Option proceeds shall not be added back to the number of shares of Common Stock available for issuance under the Plan. Upon exercise of a SAR, the number of shares of Common Stock subject to the Award that are being exercised shall be counted against the Effective Date Share Limit on the basis of one share of Common Stock for every share of Common Stock subject to such Award, regardless of the actual number of shares of Common Stock used to settle the SAR upon exercise.

------

**<u>[**Table of Contents**](#ic2d59f9bf5e7474b9ef29aaf75ccdc2b_7)</u>**

**<u>ANNEX A</u>**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;iv.Any shares of Common Stock underlying Awards granted through the assumption of, or in substitution for, outstanding awards previously granted to individuals who become employees of the Company as a result of a merger, consolidation, acquisition or other corporate transaction shall not, unless required by law or regulation, count against the reserve of available shares of Common Stock under the Plan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;d.Shares of Common Stock delivered by the Company in settlement of Awards may be authorized and unissued shares, shares held in the treasury of the Company, shares purchased on the open market or by private purchase, or a combination of the foregoing.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;e.Awards may, in the sole discretion of the Committee, be granted under the Plan in assumption of, or in substitution for, outstanding awards previously granted by an entity acquired directly or indirectly by the Company or with which the Company combines ("<u>Substitute Awards</u>"). Shares of Common Stock underlying Substitute Awards shall not be counted against the number of shares of Common Stock available for issuance pursuant to Section 5(b) above; <u>provided</u>, that Substitute Awards issued in connection with the assumption of, or in substitution for, outstanding options intended to qualify as "incentive stock options" within the meaning of Section 422 of the Code shall be counted against the aggregate number of shares of Common Stock available for Awards of Incentive Stock Options under the Plan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;f.Following the Effective Date, no new awards shall be granted under the Prior Plan. For purposes of the preceding sentence, awards under the Prior Plan with performance periods that commenced prior to the Effective Date and end after the Effective Date shall not be deemed new awards granted following the Effective Date.

**6. <u>Eligibility.</u>**

Participation shall be limited to Eligible Persons.

**7. <u>Options.</u>**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;a.<u>Generally</u>. Each Option granted under the Plan shall be evidenced by an Award Agreement. Each Option so granted shall be subject to the conditions set forth in this Section 7, and to such other conditions not inconsistent with the Plan as may be reflected in the applicable Award Agreement. All Options granted under the Plan shall be Nonqualified Stock Options unless the applicable Award Agreement expressly states that the Option is intended to be an Incentive Stock Option. Incentive Stock Options shall be granted only to Eligible Persons who are employees of the Company and its Affiliates, and no Incentive Stock Option shall be granted to any Eligible Person who is ineligible to receive an Incentive Stock Option under the Code. No Option shall be treated as an Incentive Stock Option unless the Plan has been approved by the stockholders of the Company in a manner intended to comply with the stockholder approval requirements of Section 422(b)(1) of the Code, provided that any Option intended to be an Incentive Stock Option shall not fail to be effective solely on account of a failure to obtain such approval, but rather such Option shall be treated as a Nonqualified Stock Option unless and until such approval is obtained. In the case of an Incentive Stock Option, the terms and conditions of such grant shall be subject to and comply with such rules as may be prescribed by Section 422 of the Code. If for any reason an Option intended to be an Incentive Stock Option (or any portion thereof) shall not qualify as an Incentive Stock Option, then, to the extent of such nonqualification, such Option or portion thereof shall be regarded as a Nonqualified Stock Option appropriately granted under the Plan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;b.<u>Exercise Price</u>. Except as otherwise provided by the Committee in the case of Substitute Awards, the exercise price ("<u>Exercise Price</u>") per share of Common Stock for each Option shall not be less than 100% of the Fair Market Value of such share (determined as of the Date of Grant); <u>provided</u>, <u>however</u>, that in the case of an Incentive Stock Option granted to an employee who, at the time of the grant of such Option, owns stock representing more than 10% of the voting power of all classes of stock of the Company or any Affiliate, the Exercise Price per share shall be no less than 110% of the Fair Market Value per share on the Date of Grant.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;c.<u>Vesting and Expiration</u>. Options shall vest and become exercisable in such manner and on such date or dates determined by the Committee and shall expire after such period, not to exceed ten years, as may be determined by the Committee (the "<u>Option Period</u>"); <u>provided</u>, <u>however</u>, that the Option Period shall not exceed five years from the Date of Grant in the case of an Incentive Stock Option granted to a Participant who on the Date of Grant owns stock representing more than 10% of the voting power of all classes of stock of the Company or any Affiliate; <u>provided</u>, <u>further</u>, that notwithstanding any vesting dates set by the Committee, and consistent with the Committee's power under Section 4(b), the Committee may, in its sole discretion, accelerate the exercisability of any Option upon a Change in Control, death, Disability or Retirement (or on any other termination of employment) of a Participant, which acceleration shall not affect the terms and conditions of such Option other than with respect to exercisability.

------

**<u>[**Table of Contents**](#ic2d59f9bf5e7474b9ef29aaf75ccdc2b_7)</u>**

**<u>ANNEX A</u>**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;d.<u>Method of Exercise and Form of Payment</u>. No shares of Common Stock shall be delivered pursuant to any exercise of an Option until payment in full of the Exercise Price therefor is received by the Company and the Participant has paid to the Company an amount equal to any federal, state, local and non-U.S. income and employment taxes required to be withheld. Options that have become exercisable may be exercised by delivery of written or electronic notice of exercise to the Company in accordance with the terms of the Option accompanied by payment of the Exercise Price. The Exercise Price shall be payable (i) in cash, check, cash equivalent or shares of Common Stock valued at the Fair Market Value at the time the Option is exercised (including, pursuant to procedures approved by the Committee, by means of attestation of ownership of a sufficient number of shares of Common Stock in lieu of actual delivery of such shares to the Company), provided that such shares of Common Stock are not subject to any pledge or other security interest; (ii) a "net exercise" procedure effected by withholding the minimum number of shares of Common Stock otherwise deliverable in respect of an Option that are needed to pay the Exercise Price and all applicable required withholding taxes; or (iii) by such other method as the Committee may permit in its sole discretion, including without limitation: (A) in other property having a fair market value on the date of exercise equal to the Exercise Price or (B) if there is a public market for the shares of Common Stock at such time, by means of a broker-assisted "cashless exercise" pursuant to which the Company is delivered a copy of irrevocable instructions to a stockbroker to sell the shares of Common Stock otherwise deliverable upon the exercise of the Option and to deliver promptly to the Company an amount equal to the Exercise Price. Notwithstanding the foregoing, if on the last day of the Option Period, the Fair Market Value exceeds the Exercise Price, the Participant has not exercised the Option, and the Option has not expired, such Option shall be deemed to have been exercised by the Participant on such last day by means of a net exercise and the Company shall deliver to the Participant the number of shares of Common Stock for which the Option was deemed exercised less such number of shares of Common Stock required to be withheld to cover the payment of the Exercise Price and all applicable required withholding taxes. Any fractional share of Common Stock shall be settled in cash.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;e.<u>Notification upon Disqualifying Disposition of an Incentive Stock Option</u>. Each Participant awarded an Incentive Stock Option under the Plan shall notify the Company in writing immediately after the date on which he or she makes a disqualifying disposition of any Common Stock acquired pursuant to the exercise of such Incentive Stock Option. A disqualifying disposition is any disposition (including, without limitation, any sale) of such Common Stock before the later of (i) two years after the Date of Grant of the Incentive Stock Option and (ii) one year after the date of exercise of the Incentive Stock Option. The Company may, if determined by the Committee and in accordance with procedures established by the Committee, retain possession, as agent for the applicable Participant, of any Common Stock acquired pursuant to the exercise of an Incentive Stock Option until the end of the period described in the preceding sentence, subject to complying with any instructions from such Participant as to the sale of such Common Stock.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;f.<u>Compliance with Laws, etc</u>. Notwithstanding the foregoing, in no event shall a Participant be permitted to exercise an Option in a manner that the Committee determines would violate the Sarbanes-Oxley Act of 2002, or any other applicable law or the applicable rules and regulations of the Securities and Exchange Commission or the applicable rules and regulations of any securities exchange or inter-dealer quotation system on which the securities of the Company are listed or traded.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;g.<u>No Repricing</u>. Subject to the adjustment provisions of Section 12, without the approval of the Company's stockholders, (A) the Exercise Price for any outstanding Option may not be decreased after the Date of Grant, (B) no outstanding Option may be surrendered to the Company as consideration for the grant of a new Option with a lower Exercise Price, and (C) no other modifications to any outstanding Option may be made that would be treated as a "repricing" under the then applicable rules, regulations or listing requirements adopted by the national securities exchange on which the Company's Common Stock is listed. Neither the Board nor the Committee shall offer a cash buy-out of "underwater" Options, and such buyouts of "underwater" Options shall be prohibited.

**8. <u>Stock Appreciation Rights.</u>**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<u>a.</u><u>Generally</u>. Each SAR granted under the Plan shall be evidenced by an Award Agreement. Each SAR so granted shall be subject to the conditions set forth in this Section 8, and to such other conditions not inconsistent with the Plan as may be reflected in the applicable Award Agreement. Any Option granted under the Plan may include tandem SARs. The Committee also may award SARs to Eligible Persons independent of any Option.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;b.<u>Strike Price</u>. Except as otherwise provided by the Committee in the case of Substitute Awards, the strike price ("<u>Strike Price</u>") per share of Common Stock for each SAR shall not be less than 100% of the Fair Market Value of such share (determined as of the Date of Grant). Notwithstanding the foregoing, a SAR granted in tandem with (or

------

**<u>[**Table of Contents**](#ic2d59f9bf5e7474b9ef29aaf75ccdc2b_7)</u>**

**<u>ANNEX A</u>**

in substitution for) an Option previously granted shall have a Strike Price at least equal to the Exercise Price of the corresponding Option.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;c.<u>Vesting and Expiration</u>. A SAR granted in connection with an Option shall become exercisable and shall expire according to the same vesting schedule and expiration provisions as the corresponding Option. A SAR granted independent of an Option shall vest and become exercisable and shall expire in such manner and on such date or dates determined by the Committee and shall expire after such period, not to exceed ten years, as may be determined by the Committee (the "<u>SAR Period</u>"); <u>provided</u>, <u>however</u>, that notwithstanding any vesting dates set by the Committee, and consistent with the Committee's power under Section 4(b), the Committee may, in its sole discretion, accelerate the exercisability of any SAR upon a Change in Control, death, Disability or Retirement (or on any other termination of employment) of a Participant, which acceleration shall not affect the terms and conditions of such SAR other than with respect to exercisability.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;d.<u>Method of Exercise</u>. SARs that have become exercisable may be exercised by delivery of written or electronic notice of exercise to the Company in accordance with the terms of the Award, specifying the number of SARs to be exercised and the date on which such SARs were awarded. Notwithstanding the foregoing, if on the last day of the Option Period (or in the case of a SAR independent of an Option, the SAR Period), the Fair Market Value exceeds the Strike Price, the Participant has not exercised the SAR or the corresponding Option (if applicable), and neither the SAR nor the corresponding Option (if applicable) has expired, such SAR shall be deemed to have been exercised by the Participant on such last day and the Company shall make the appropriate payment therefor.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;e.<u>Payment</u>. Upon the exercise of a SAR, the Company shall pay to the Participant an amount equal to the number of shares subject to the SAR that are being exercised multiplied by the excess, if any, of the Fair Market Value of one share of Common Stock on the exercise date over the Strike Price, less an amount equal to any federal, state, local and non-U.S. income and employment taxes required to be withheld. The Company shall pay such amount in cash, in shares of Common Stock valued at Fair Market Value, or any combination thereof, as determined by the Committee. Any fractional share of Common Stock shall be settled in cash.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;f.<u>Substitution of SARs for Nonqualified Stock Options</u>. The Committee shall have the authority in its sole discretion to substitute, without the consent of the affected Participant or any holder or beneficiary of SARs, SARs settled in shares of Common Stock (or settled in shares or cash in the sole discretion of the Committee) for outstanding Nonqualified Stock Options, provided that (i) the substitution shall not otherwise result in a modification of the terms of any such Nonqualified Stock Option, (ii) the number of shares of Common Stock underlying the substituted SARs shall be the same as the number of shares of Common Stock underlying such Nonqualified Stock Options and (iii) the Strike Price of the substituted SARs shall be equal to the Exercise Price of such Nonqualified Stock Options; <u>provided</u>, <u>however</u>, that if, in the opinion of the Company's independent public auditors, the foregoing provision creates adverse accounting consequences for the Company, such provision shall be considered null and void.

**9. <u>Restricted Stock and Restricted Stock Units.</u>**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;a.<u>Generally</u>. Each grant of Restricted Stock and Restricted Stock Units shall be evidenced by an Award Agreement. Each Restricted Stock and Restricted Stock Unit grant shall be subject to the conditions set forth in this Section 9, and to such other conditions not inconsistent with the Plan as may be reflected in the applicable Award Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;b.<u>Stock Certificates and Book Entry; Escrow or Similar Arrangement</u>. Upon the grant of Restricted Stock, the Committee shall cause a stock certificate registered in the name of the Participant to be issued or shall cause share(s) of Common Stock to be registered in the name of the Participant and held in book-entry form subject to the Company's directions and, if the Committee determines that the Restricted Stock shall be held by the Company or in escrow rather than delivered to the Participant pending the release of the applicable restrictions, the Committee may require the Participant to additionally execute and deliver to the Company (i) an escrow agreement satisfactory to the Committee, if applicable, and (ii) the appropriate stock power (endorsed in blank) with respect to the Restricted Stock covered by such agreement. If a Participant shall fail to execute an agreement evidencing an Award of Restricted Stock and, if applicable, an escrow agreement and blank stock power within the amount of time specified by the Committee, the Award shall be null and void. Subject to the restrictions set forth in this Section 9 and the applicable Award Agreement, the Participant generally shall have the rights and privileges of a stockholder as to such Restricted Stock, including without limitation the right to vote such Restricted Stock. To the extent that shares of Restricted Stock are forfeited, any stock certificates issued to the Participant evidencing such shares shall be returned to the Company, and all rights of the Participant to such shares and as a stockholder with respect thereto shall terminate without further obligation on the part of the Company.

**<u>ANNEX A</u>**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;c.<u>Vesting; Acceleration of Lapse of Restrictions</u>. The Restricted Period with respect to Restricted Stock and Restricted Stock Units shall lapse in such manner and on such date or dates determined by the Committee and the Committee shall determine the treatment of the unvested portion of Restricted Stock and Restricted Stock Units upon termination of employment or service of the Participant granted the applicable Award. Consistent with the Committee's power under Section 4(b), the Committee may in its sole discretion accelerate the lapse of any or all of the restrictions on the Restricted Stock and Restricted Stock Units upon a Change in Control, death, Disability or Retirement (or on any other termination of employment) of a Participant, which acceleration shall not affect any other terms and conditions of such Awards.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;d.<u>Delivery of Restricted Stock and Settlement of Restricted Stock Units</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;i.Upon the expiration of the Restricted Period with respect to any shares of Restricted Stock, the restrictions set forth in the applicable Award Agreement shall be of no further force or effect with respect to such shares, except as set forth in the applicable Award Agreement. If an escrow arrangement is used, upon such expiration, the Company shall deliver to the Participant, or his or her beneficiary, without charge, the stock certificate (or, if applicable, a notice evidencing a book entry notation) evidencing the shares of Restricted Stock that have not then been forfeited and with respect to which the Restricted Period has expired (rounded down to the nearest full share). Dividends, if any, that may have been withheld by the Committee and attributable to any particular share of Restricted Stock shall be distributed to the Participant in cash or, at the sole discretion of the Committee, in shares of Common Stock having a Fair Market Value equal to the amount of such dividends, upon the release of restrictions on such share and, if such share is forfeited, the Participant shall have no right to such dividends. Dividends and dividend equivalents credited or payable in connection with an Award of Restricted Stock that has not yet vested shall be subject to the same restrictions and risk of forfeiture as the underlying Award and shall not be paid until the underlying Award vests.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;ii.Unless otherwise provided by the Committee in the applicable Award Agreement, upon the expiration of the Restricted Period with respect to any outstanding Restricted Stock Units, the Company shall deliver to the Participant, or his or her beneficiary, without charge, one share of Common Stock (or other securities or other property, as applicable) for each such outstanding Restricted Stock Unit; <u>provided</u>, <u>however</u>, that the Committee may, in its sole discretion, elect to (A) pay cash or part cash and part Common Stock in lieu of delivering only shares of Common Stock in respect of such Restricted Stock Units or (B) defer the delivery of Common Stock (or cash or part Common Stock and part cash, as the case may be) beyond the expiration of the Restricted Period. If a cash payment is made in lieu of delivering shares of Common Stock, the amount of such payment shall be equal to the Fair Market Value of the Common Stock as of the date on which the Restricted Period lapsed with respect to such Restricted Stock Units. To the extent provided in the applicable Award Agreement, the holder of outstanding Restricted Stock Units shall be entitled to be credited with dividend equivalent payments (upon the payment by the Company of dividends on shares of Common Stock) either in cash or, at the sole discretion of the Committee, in shares of Common Stock having a Fair Market Value equal to the amount of such dividends, upon the release of restrictions on such Restricted Stock Units, and, if such Restricted Stock Units are forfeited, the Participant shall have no right to such dividend equivalent payments. Dividends and dividend equivalents credited or payable in connection with an Award of Restricted Stock Units that has not yet vested shall be subject to the same restrictions and risk of forfeiture as the underlying Award and shall not be paid until the underlying Award vests.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;e.<u>Legends on Restricted Stock</u>. Each certificate representing Restricted Stock awarded under the Plan, if any, shall bear a legend substantially in the form of the following, in addition to any other information the Company deems appropriate, until the lapse of all restrictions with respect to such Common Stock:

TRANSFER OF THIS CERTIFICATE AND THE SHARES REPRESENTED HEREBY IS RESTRICTED PURSUANT TO THE TERMS OF THE ATRICURE, INC. 2023 STOCK INCENTIVE PLAN AND A RESTRICTED STOCK AWARD AGREEMENT, BETWEEN ATRICURE, INC. AND PARTICIPANT. A COPY OF SUCH PLAN AND AWARD AGREEMENT IS ON FILE AT THE PRINCIPAL EXECUTIVE OFFICES OF ATRICURE, INC.

**10. <u>Other Stock-Based Awards.</u>**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;a.<u>Generally</u>. The Committee may issue unrestricted Common Stock or rights under the Company's other incentive programs that, subject to the terms and conditions thereof, provide for the right to receive grants of Awards at a future date, or other Awards denominated in Common Stock, under the Plan to Eligible Persons, alone or in tandem with other Awards, in such amounts as the Committee shall from time to time in its sole discretion

**<u>ANNEX A</u>**

determine. Each Other Stock-Based Award granted under the Plan shall be evidenced by an Award Agreement. Each Other Stock-Based Award so granted shall be subject to such conditions not inconsistent with the Plan as may be reflected in the applicable Award Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;b.<u>Non-Employee Director Awards</u>. The Committee shall grant Awards to each Non-Employee Director as part of the retainer for Non-Employee Director service. The number of shares of Common Stock underlying the Awards granted to each Non-Employee Director shall be the number of shares of Common Stock equal to the award value divided by the Fair Market Value of a share of Common Stock on the Date of Grant. Notwithstanding the foregoing, the Committee may grant Options, Restricted Stock Units, Restricted Stock or other types of Awards contemplated by this Plan. Subject to the limitations in Section 5(b)(iii), the Committee shall have the authority to establish the award value annually. As of the Effective Date of the Plan, the Committee has established the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;i.<u>Automatic Grants</u>. Each Non-Employee Director shall automatically be granted (A) shares of Restricted Stock worth $175,000 of Common Stock, as valued on the Date of Grant, upon, or in connection with, commencement of service as a director of the Company, and (B) Restricted Stock worth $150,000 of Common Stock, as valued on the Date of Grant, at each annual meeting of the Company's stockholders. All such Restricted Stock shall be subject to the terms and conditions of this Plan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;ii.<u>Vesting of Restricted Stock Granted to Non-Employee Directors</u>. Each initial grant of Restricted Stock granted to a newly elected or appointed Non-Employee Director shall vest in three (3) successive equal annual installments over the Non-Employee Director's period of continued service as a director, with the first such installment to vest upon the Non-Employee Director's completion of one (1) year of service as a Non-Employee Director measured from the Date of Grant. Each annual grant of Restricted Stock granted to continuing Non-Employee Directors shall vest upon the Non-Employee Director's completion of one (1) year of service as a Non-Employee Director measured from the Date of Grant.

**11. <u>Performance Compensation Awards.</u>**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;a.<u>Generally</u>. The Committee shall have the authority, at the time of grant of any Award described in Section 9 or 10 of the Plan, to designate such Award as a Performance Compensation Award. The Committee shall also have the authority to grant a standalone cash-based Performance Compensation Award pursuant to this Section 11.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;b.<u>Discretion of Committee with Respect to Performance Compensation Awards</u>. With regard to a particular Performance Period, the Committee shall have sole discretion to select the length of such Performance Period, the type(s) of Performance Compensation Awards to be issued, the Performance Criteria that will be used to establish the Performance Goal(s), the kind(s) and/or level(s) of the Performance Goals(s) that is (are) to apply, the Performance Formula, and the form of settlement for such Award. With regard to the Performance Compensation Awards to be issued for such Performance Period, the Committee may exercise its discretion with respect to each of the matters enumerated in the immediately preceding sentence and record the same in writing.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;c.<u>Performance Criteria</u>. The Performance Criteria that will be used to establish the Performance Goal(s) may be based on the attainment of specific levels of performance of the Company (and/or one or more Affiliates, divisions or operational units, or any combination of the foregoing) and may include, but shall not be limited to, the following: (i) net earnings or net income (before or after taxes); (ii) basic or diluted earnings per share (before or after taxes); (iii) net revenue or net revenue growth; (iv) gross revenue, gross revenue growth; (v) gross profit or gross profit growth; (vi) net operating profit (before or after taxes); (vii) return measures (including, but not limited to, stockholder return, TSR, return on investment, assets (including net assets), capital, invested capital, equity, or sales); (viii) cash flow measures (including, but not limited to, operating cash flow, free cash flow, and cash flow return on capital); (ix) earnings before or after taxes, interest, depreciation or amortization; (x) gross or operating margins; (xi) productivity ratios; (xii) share price (including, but not limited to, growth measures and total stockholder return); (xiii) expense targets; (xiv) operating efficiency; (xv) objective measures of customer satisfaction; (xvi) working capital targets; (xvii) measures of economic value added; (xviii) inventory control; (xix) enterprise value; (xx) sales; (xxi) stockholder return; (xxii); client retention; (xxiii) competitive market metrics; (xxiv) employee retention; (xxv) timely completion of new product rollouts; (xxvi) timely launch of new facilities; (xxvii) objective measures of personal targets, goals or completion of projects (including, but not limited to, succession and hiring projects, completion of specific acquisitions, reorganizations or other corporate transactions, expansions of specific business operations and meeting divisional or project budgets); (xxviii) any other objective or subjective criteria, including individual performance criteria, as determined by the Committee; or (xxix) any combination of the foregoing. Performance Criteria also may include measures related to environmental, social and/or governance ("<u>ESG</u>") matters, including, without limitation, matters related to people, retention, hiring, headcount, and diversity, equity and inclusion ("<u>DEI</u>"). Any one or more of the Performance

**<u>ANNEX A</u>**

Criteria may be used on an absolute, adjusted, or relative basis to measure the performance of the Company and/or one or more Affiliates as a whole or any divisional or operational unit(s) of the Company and/or one or more Affiliates or any combination thereof, as the Committee may deem appropriate, or any of the above Performance Criteria may be compared to the performance of a selected group of comparison companies, or a published or special index that the Committee, in its sole discretion, deems appropriate, or as compared to various stock market indices. The Committee also has the authority to provide for accelerated vesting of any Award based on the achievement of Performance Goals pursuant to the Performance Criteria specified in this paragraph.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;d.<u>Modification of Performance Goal(s)</u>. The Committee may alter Performance Criteria or modify the calculation of a Performance Goal without obtaining stockholder approval to reflect any event that would reasonably be expected to affect or alter such Performance Criteria or Performance Goal, including, but not limited to: (i) asset write-downs; (ii) litigation or claim judgments or settlements; (iii) the effect of changes in tax laws, accounting principles, or other laws or regulatory rules affecting reported results; (iv) any reorganization and restructuring programs; (v) nonrecurring items; (vi) acquisitions or divestitures; (vii) any other specific unusual or infrequently occurring events, or objectively determinable category thereof; (viii) foreign exchange gains and losses; (ix) a change in the Company's fiscal year; or (x) any other event as determined by the Committee.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;e.<u>Payment of Performance Compensation Awards.</u>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;i.<u>Condition to Receipt of Payment</u>. Unless otherwise provided in the applicable Participant Agreement, a Participant must be employed by the Company on the last day of a Performance Period to be eligible for payment in respect of a Performance Compensation Award for such Performance Period.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;ii.<u>Limitation</u>. Unless otherwise provided in the applicable Participant Agreement, a Participant shall be eligible to receive payment in respect of a Performance Compensation Award only to the extent that (A) the Performance Goals for such period are achieved; and (B) all or some of the portion of such Participant's Performance Compensation Award has been earned for the Performance Period based on the application of the Performance Formula to such achieved Performance Goals.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;iii.<u>Use of Negative Discretion</u>. In determining the actual amount of an individual Participant's Performance Compensation Award for a Performance Period, the Committee may reduce or eliminate the amount of the Performance Compensation Award earned under the Performance Formula in the Performance Period through the use of Negative Discretion if, in its sole judgment, such reduction or elimination is appropriate.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;f.<u>Timing of Award Payments</u>. Unless otherwise provided in the applicable Award Agreement, Performance Compensation Awards granted for a Performance Period shall be paid to Participants as soon as administratively practicable following the Committee's determination of the amount earned. Unless otherwise provided in the applicable Award Agreement, any Performance Compensation Award that is otherwise payable in shares of Common Stock shall be credited (during the period between the Date of Grant and the payment date) with dividend equivalents (in a manner consistent with the methodology set forth in the last sentence of Section 9(d)(ii)).

**12. <u>Changes in Capital Structure and Similar Events.</u>**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;a.<u>Dilution and Other Adjustments.</u> In the event of any merger, reorganization, consolidation, liquidation, recapitalization, reclassification, redesignation, stock dividend, other extraordinary distribution (whether in the form of cash, shares or otherwise), stock split, reverse stock split, spin off, combination, repurchase or exchange of shares or issuance of warrants or rights to purchase shares or other securities, or other change in corporate structure affecting the Common Stock of the Company, the Committee may make such adjustments in the aggregate number and type of shares which may be delivered and the individual award maximums as set forth in Section 5, the number and type of shares subject to outstanding Awards and the Exercise Price or other price of shares of Common Stock subject to outstanding Awards (provided the number of shares of Common Stock subject to any Award shall always be a whole number), as may be and to the extent determined to be appropriate and equitable by the Committee, in its sole discretion, to prevent dilution or enlargement of the benefits or potential benefits intended to be made available under the Plan. Such adjustment shall be conclusive and binding for all purposes of the Plan. The Committee shall determine whether and the extent to which any recapitalization, extraordinary distribution, reclassification, repurchase or exchange of shares or other event requires any such adjustment. Any such adjustment of an ISO or SAR shall be made in compliance with Code Sections 422 and 424, and no such adjustment shall be made that would cause any Award which is or becomes subject to Code Section 409A to fail to comply with the requirements of Code Section 409A or is exempt from Code Section 409A to become subject to Code Section 409A.

**<u>ANNEX A</u>**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;b.<u>Change in Control</u>. Notwithstanding any other provision of the Plan to the contrary, immediately upon the occurrence of a Change in Control, the following provisions of this Section 12(b) shall apply except to the extent that (A) the applicable Award is assumed or an equivalent option or right substituted by the successor corporation or a parent or subsidiary of the successor corporation; or (B) an Award Agreement provides for a different treatment (in which case the Award Agreement shall govern):

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;i.all outstanding Options and SARs vest and become fully exercisable; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;ii.all Full-Value Awards become fully vested and all Performance Goals or other vesting criteria will be deemed achieved at target levels and all other terms and conditions met

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;c.<u>Termination</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;i.<u>Termination by Death, Disability, or Retirement.</u> Subject to Section 14(b), if a Participant's employment by the Company terminates by reason of death, Disability or Retirement, or in the case of an advisory relationship if such business relationship terminates by reason of death or Disability, any Award held by such Participant, unless otherwise determined by the Committee at grant or otherwise interpreted pursuant to Section 14(u) hereof, shall be fully vested and may thereafter be exercised by the Participant or by the Participant's beneficiary or legal representative, for a period of one (1) year following termination of employment, in the case of death or Disability, and 90 days in the case of Retirement, or such longer period as the Committee may specify at or after grant in all cases other than ISOs, or until the expiration of the stated term of such Award, whichever period is shorter; provided, that unless otherwise provided in an Award Agreement, for Full-Value Awards conditioned on achievement of Performance Goals, no vesting may occur and/or no distribution may be made in the case of Retirement prior to the attainment of Performance Goals.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;ii.<u>Termination for Cause.</u> If a Participant's employment or service terminates for Cause, (A) all Options and SARs (or portions thereof) which have not been exercised, whether vested or not, and (B) all unvested Full-Value Awards, shall immediately be forfeited upon termination, including such Awards that are subject to performance conditions (or unearned portions thereof).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;iii.<u>Other Terminations.</u> If a Participant's employment or service terminates, voluntarily or involuntarily, for any reason other than death, Disability, Retirement or Cause, (A) any vested portion of Options or SARs held by the Participant at the time of termination may be exercised for a period of three months (or such other period as the Committee may specify at or after the time of grant) from the termination date, or until the expiration of the original term of the Option or SAR, whichever period is shorter, (B) no unvested portion of any Option or SAR shall become vested, including such Awards that are subject to performance conditions (or unearned portions thereof), and (C) all unvested Full-Value Awards, including such Awards that are subject to performance conditions (or unearned portions thereof), shall immediately be forfeited upon termination.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;iv.<u>Limitation for ISOs.</u> No ISO may be exercised more than three months following termination of employment for any reason (including Retirement) other than death or Disability, nor more than one year following termination of employment for the reason of death or Disability (as defined in Code Section 422), or such Award will no longer qualify as an ISO and shall thereafter be, and receive the tax treatment applicable to, a NQSO. For this purpose, a termination of employment is cessation of employment, under the rules applicable to ISOs, such that no employment relationship exists between the Participant and the Company.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;v.<u>Transfers and Leaves of Absence.</u> The transfer of a Participant within the Company shall not be deemed a termination of employment except as required by Sections 422 and 409A of the Code, and other applicable laws. The following leaves of absences are not deemed to be a termination of employment:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A.if approved in writing by the Company, for military service, sickness or any other purpose approved by the Company, and the period of absence does not exceed 90 days;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;B.if in excess of 90 days, if approved in writing by the Company, but only if the Participant's right to reemployment is guaranteed by statute or contract and provided that the Participant returns to work within 30 days after the end of such absence; and

**13. <u>Amendments and Termination.</u>** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;a.<u>Amendment and Termination of the Plan</u>. The Board may amend, alter, suspend, discontinue, or terminate the Plan or any portion thereof at any time; <u>provided</u>, that no such amendment, alteration, suspension, discontinuation or termination shall be made without stockholder approval if such approval is necessary to comply with any regulatory requirement applicable to the Plan (including, without limitation, as necessary to comply with any rules or regulations of any securities exchange or inter-dealer quotation system on which the securities of the Company may be listed or quoted); <u>provided</u>, <u>further</u>, that any such amendment, alteration, suspension, discontinuance or termination that would materially and adversely affect the rights of any Participant or any holder or beneficiary of any Award theretofore granted shall not to that extent be effective without the consent of the affected Participant, holder or beneficiary. Notwithstanding the foregoing, no amendment shall be made to the last proviso of Section 13(b) without stockholder approval.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;b.<u>Amendment of Award Agreements</u>. The Committee may, to the extent consistent with the terms of any applicable Award Agreement, waive any conditions or rights under, amend any terms of, or alter, suspend, discontinue, cancel or terminate, any Award theretofore granted or the associated Award Agreement, prospectively or retroactively; <u>provided</u> that any such waiver, amendment, alteration, suspension, discontinuance, cancellation or termination that would materially and adversely affect the rights of any Participant with respect to any Award theretofore granted shall not to that extent be effective without the consent of the affected Participant; <u>provided</u>, <u>further</u>, that without stockholder approval, except as otherwise permitted under Section 12 of the Plan, (i) no amendment or modification may reduce the Exercise Price of any Option or the Strike Price of any SAR, (ii) the Committee may not cancel any outstanding Option or SAR and replace it with a new Option or SAR (with a lower Exercise Price or Strike Price, as the case may be) or other Award or cash in a manner which would result in any "repricing" for financial statement reporting purposes (or otherwise cause the Award to fail to qualify for equity accounting treatment) and (iii) the Committee may not take any other action which is considered a "repricing" for purposes of the stockholder approval rules of any securities exchange or inter-dealer quotation system on which the securities of the Company are listed or quoted.

**14. <u>General.</u>**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;a.<u>Award Agreements</u>. Each Award under the Plan shall be evidenced by an Award Agreement, which shall be delivered to the Participant and shall specify the terms and conditions of the Award and any rules applicable thereto, including, without limitation, the effect on such Award of the death, Disability or termination of employment or service of a Participant, or of such other events as may be determined by the Committee. For purposes of the Plan, an Award Agreement may be in any such form (written or electronic) as determined by the Committee (including, without limitation, a Board or Committee resolution, an employment agreement, a notice, a certificate or a letter) evidencing the Award. The Committee need not require an Award Agreement to be signed by the Participant or a duly authorized representative of the Company.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;b.<u>Minimum Vesting Requirement</u>. Notwithstanding any other provision of the Plan to the contrary, Awards granted under the Plan (other than cash-based Awards) shall vest no earlier than the first anniversary of the date on which the Award is granted; <u>provided</u>, that the following Awards shall not be subject to the foregoing minimum vesting requirement: any (i) Substitute Awards, (ii) Shares delivered in lieu of fully vested cash Awards, (iii) Awards to Eligible Directors that vest on the earlier of the one-year anniversary of the date of grant and the next annual meeting of stockholders which is at least 50 weeks after the immediately preceding year's annual meeting, and (iv) any additional Awards the Committee may grant, up to a maximum of five percent (5%) of the available share reserve authorized for issuance under the Plan pursuant to Section 5(b) (subject to adjustment under Section 12); and, <u>provided</u>, <u>further</u>, that the foregoing restriction does not apply to the Committee's discretion to provide for accelerated exercisability or vesting of any Award, including in cases of Retirement, death, Disability or a Change in Control, in the terms of the Award or otherwise.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;c.<u>Nontransferability</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;i.Each Award shall be exercisable only by a Participant during the Participant's lifetime, or, if permissible under applicable law, by the Participant's legal guardian or representative. No Award may be assigned, alienated, pledged, attached, sold or otherwise transferred or encumbered by a Participant other than by will or by the laws of descent and distribution, and any such purported assignment, alienation, pledge,

**<u>ANNEX A</u>**

attachment, sale, transfer or encumbrance shall be void and unenforceable against the Company or an Affiliate; provided, that the designation of a beneficiary shall not constitute an assignment, alienation, pledge, attachment, sale, transfer or encumbrance.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;ii.Notwithstanding the foregoing, the Committee may, in its sole discretion, permit Awards (other than Incentive Stock Options) to be transferred by a Participant, without consideration, subject to such rules as the Committee may adopt consistent with any applicable Award Agreement to preserve the purposes of the Plan, to (A) any person who is a "family member" of the Participant, as such term is used in the instructions to Form S-8 under the Securities Act (collectively, "<u>Immediate Family Members</u>"); (B) a trust solely for the benefit of the Participant and his or her Immediate Family Members; (C) a partnership or limited liability company whose only partners or stockholders are the Participant and his or her Immediate Family Members; or (D) any other transferee as may be approved either (1) by the Board or the Committee, as applicable, in its sole discretion, or (2) as provided in the applicable Award Agreement (each transferee described in clause (A), (B), (C) or (D) above is hereinafter referred to as a "<u>Permitted Transferee</u>") provided that the Participant gives the Committee advance written notice describing the terms and conditions of the proposed transfer and the Committee notifies the Participant in writing that such a transfer would comply with the requirements of the Plan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;iii.The terms of any Award transferred in accordance with the immediately preceding sentence shall apply to the Permitted Transferee, and any reference in the Plan, or in any applicable Award Agreement, to a Participant shall be deemed to refer to the Permitted Transferee, except that (A) Permitted Transferees shall not be entitled to transfer any Award, other than by will or the laws of descent and distribution; (B) Permitted Transferees shall not be entitled to exercise any transferred Option unless there shall be in effect a registration statement on an appropriate form covering the shares of Common Stock to be acquired pursuant to the exercise of such Option if the Committee determines, consistent with any applicable Award Agreement, that such a registration statement is necessary or appropriate; (C) the Committee or the Company shall not be required to provide any notice to a Permitted Transferee, whether or not such notice is or would otherwise have been required to be given to the Participant under the Plan or otherwise; and (D) the consequences of the termination of the Participant's employment by, or services to, the Company or an Affiliate under the terms of the Plan and the applicable Award Agreement shall continue to be applied with respect to the Participant, including, without limitation, that an Option shall be exercisable by the Permitted Transferee only to the extent, and for the periods, specified in the Plan and the applicable Award Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;d.<u>Dividends and Dividend Equivalents</u>. The Committee in its sole discretion may provide a Participant as part of an Award with dividends or dividend equivalents, payable in cash, shares of Common Stock, other securities, other Awards or other property, on a current or deferred basis, on such terms and conditions as may be determined by the Committee in its sole discretion, including, without limitation, payment directly to the Participant, withholding of such amounts by the Company subject to vesting of the Award or reinvestment in additional shares of Common Stock, Restricted Stock or other Awards. However, dividends and dividend equivalents credited or payable in connection with an Award that has not yet vested shall be subject to the same restrictions and risk of forfeiture as the underlying Award and shall not be paid until the underlying Award vests.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;e.<u>Tax Withholding.</u>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;i.A Participant shall be required to pay to the Company or any Affiliate, and the Company or any Affiliate shall have the right and is hereby authorized to withhold, from any cash, shares of Common Stock, other securities or other property deliverable under any Award or from any compensation or other amounts owing to a Participant, the amount (in cash, Common Stock, other securities or other property) of any required withholding taxes in respect of an Award, its exercise, or any payment or transfer under an Award or under the Plan and to take such other action as may be necessary in the opinion of the Committee or the Company to satisfy all obligations for the payment of such withholding and taxes.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;ii.Without limiting the generality of clause (i) above, the Committee may, in its sole discretion, permit a Participant to satisfy, in whole or in part, the foregoing withholding liability (but no more than the maximum required statutory withholding liability) by (A) the delivery of shares of Common Stock (which are not subject to any pledge or other security interest) owned by the Participant having a Fair Market Value equal to such withholding liability or (B) having the Company withhold from the number of shares of Common Stock otherwise issuable or deliverable pursuant to the exercise or settlement of the Award a number of shares with a Fair Market Value equal to such withholding liability. A Participant may elect to satisfy such withholding liability through cash or cash proceeds.

**<u>ANNEX A</u>**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;f.<u>No Claim to Awards; No Rights to Continued Employment; Waiver</u>. No employee of the Company or an Affiliate, or other person, shall have any claim or right to be granted an Award under the Plan or, having been selected for the grant of an Award, to be selected for a grant of any other Award. There is no obligation for uniformity of treatment of Participants or holders or beneficiaries of Awards. The terms and conditions of Awards and the Committee's determinations and interpretations with respect thereto need not be the same with respect to each Participant and may be made selectively among Participants, whether or not such Participants are similarly situated. Neither the Plan nor any action taken hereunder shall be construed as giving any Participant any right to be retained in the employ or service of the Company or an Affiliate, nor shall it be construed as giving any Participant any rights to continued service on the Board. The Company or any of its Affiliates may at any time dismiss a Participant from employment or discontinue any consulting relationship, free from any liability or any claim under the Plan, unless otherwise expressly provided in the Plan or any Award Agreement. By accepting an Award under the Plan, a Participant shall thereby be deemed to have waived any claim to continued exercise or vesting of an Award or to damages or severance entitlement related to non-continuation of the Award beyond the period provided under the Plan or any Award Agreement, notwithstanding any provision to the contrary in any written employment contract or other agreement between the Company and its Affiliates and the Participant, whether any such agreement is executed before, on or after the Date of Grant.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;g.<u>International Participants</u>. With respect to Participants who reside or work outside of the United States of America, the Committee may in its sole discretion amend the terms of the Plan or Sub Plans or outstanding Awards with respect to such Participants in order to conform such terms with the requirements of local law or to obtain more favorable tax or other treatment for a Participant, the Company or its Affiliates.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;h.<u>Designation and Change of Beneficiary</u>. Each Participant may file with the Committee a written designation of one or more persons as the beneficiary or beneficiaries, as applicable, who shall be entitled to receive the amounts payable with respect to an Award, if any, due under the Plan upon his or her death. A Participant may, from time to time, revoke or change his or her beneficiary designation without the consent of any prior beneficiary by filing a new designation with the Committee. The last such designation received by the Committee shall be controlling; <u>provided</u>, <u>however</u>, that no designation, or change or revocation thereof, shall be effective unless received by the Committee prior to the Participant's death, and in no event shall it be effective as of a date prior to such receipt. If no beneficiary designation is filed by a Participant, the beneficiary shall be deemed to be his or her spouse or, if the Participant is unmarried at the time of death, his or her estate.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;i.<u>Termination of Employment</u>. Except as otherwise provided in the applicable Participant Agreement, unless determined otherwise by the Committee at any point following such event: (i) neither a temporary absence from employment or service due to illness, vacation or leave of absence nor a transfer from employment or service with the Company to employment or service with an Affiliate (or vice-versa) shall be considered a termination of employment or service of such Participant with the Company or an Affiliate; and (ii) if a Participant's employment with the Company and its Affiliates terminates, but such Participant continues to provide services to the Company and its Affiliates in a non-employee capacity, such change in status shall not be considered a termination of employment or service of such Participant with the Company or an Affiliate for purposes of the Plan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;j.<u>No Rights as a Stockholder</u>. Except as otherwise specifically provided in the Plan or any Award Agreement, no person shall be entitled to the privileges of ownership in respect of shares of Common Stock that are subject to Awards hereunder until such shares have been issued or delivered to that person.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;k.<u>Government and Other Regulations</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;i.The obligation of the Company to settle Awards in Common Stock or other consideration shall be subject to all applicable laws, rules, and regulations, and to such approvals by governmental agencies as may be required. Notwithstanding any terms or conditions of any Award to the contrary, the Company shall be under no obligation to offer to sell or to sell, and shall be prohibited from offering to sell or selling, any shares of Common Stock pursuant to an Award unless such shares have been properly registered for sale pursuant to the Securities Act with the Securities and Exchange Commission or unless the Company has received an opinion of counsel, satisfactory to the Company, that such shares may be offered or sold without such registration pursuant to an available exemption therefrom and the terms and conditions of such exemption have been fully complied with. The Company shall be under no obligation to register for sale under the Securities Act any of the shares of Common Stock to be offered or sold under the Plan. The Committee shall have the authority to provide that all shares of Common Stock or other securities of the Company or any Affiliate delivered under the Plan shall be subject to such stop transfer orders and other restrictions as the Committee may deem advisable under the Plan, the applicable Award

Agreement, the federal securities laws, or the rules, regulations and other requirements of the Securities and Exchange Commission, any securities exchange or inter-dealer quotation system on which the securities of the Company are listed or quoted and any other applicable federal, state, local or non-U.S. laws, and, without limiting the generality of Section 9 of the Plan, the Committee may cause a legend or legends to be put on certificates representing shares of Common Stock or other securities of the Company or any Affiliate delivered under the Plan to make appropriate reference to such restrictions or may cause such Common Stock or other securities of the Company or any Affiliate delivered under the Plan in book-entry form to be held subject to the Company's instructions or subject to appropriate stop-transfer orders. Notwithstanding any provision in the Plan to the contrary, the Committee reserves the right to add any additional terms or provisions to any Award granted under the Plan that it in its sole discretion deems necessary or advisable in order that such Award complies with the legal requirements of any governmental entity to whose jurisdiction the Award is subject.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;ii.The Committee may cancel an Award or any portion thereof if it determines, in its sole discretion, that legal or contractual restrictions, blockage, other market considerations or any combination of the foregoing would make the Company's acquisition of shares of Common Stock from the public markets, the Company's issuance of Common Stock to the Participant, the Participant's acquisition of Common Stock from the Company or the Participant's sale of Common Stock to the public markets, illegal, impracticable or inadvisable. If the Committee determines to cancel all or any portion of an Award in accordance with the foregoing, the Company shall pay to the Participant an amount equal to the excess of (A) the aggregate Fair Market Value of the shares of Common Stock subject to such Award or portion thereof canceled (determined as of the applicable exercise date, or the date that the shares would have been vested or delivered, as applicable), over (B) the aggregate Exercise Price or Strike Price (in the case of an Option or SAR, respectively) or any amount payable as a condition of delivery of shares of Common Stock (in the case of any other Award). Such amount shall be delivered to the Participant as soon as practicable following the cancellation of such Award or portion thereof.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;l.<u>No Section 83(b) Elections Without Consent of Company</u>. No election under Section 83(b) of the Code or under a similar provision of law may be made unless expressly permitted by the terms of the applicable Award Agreement or by action of the Committee in writing prior to the making of such election. If a Participant, in connection with the acquisition of shares of Common Stock under the Plan or otherwise, is expressly permitted to make such election and the Participant makes the election, the Participant shall notify the Company of such election within ten days of filing notice of the election with the Internal Revenue Service or other governmental authority, in addition to any filing and notification required pursuant to Section 83(b) of the Code or other applicable provision.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;m.<u>Payments to Persons Other Than Participants</u>. If the Committee shall find that any person to whom any amount is payable under the Plan is unable to care for his or her affairs because of illness or accident, or is a minor, or has died, then any payment due to such person or his or her estate (unless a prior claim therefor has been made by a duly appointed legal representative) may, if the Committee so directs the Company, be paid to his or her spouse, child, relative, an institution maintaining or having custody of such person, or any other person deemed by the Committee to be a proper recipient on behalf of such person otherwise entitled to payment. Any such payment shall be a complete discharge of the liability of the Committee and the Company therefor.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;n.<u>Nonexclusivity of the Plan</u>. Neither the adoption of this Plan by the Board nor the submission of this Plan to the stockholders of the Company for approval shall be construed as creating any limitations on the power of the Board to adopt such other incentive arrangements as it may deem desirable, including, without limitation, the granting of stock options otherwise than under this Plan, and such arrangements may be either applicable generally or only in specific cases.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;o.<u>No Trust or Fund Created</u>. Neither the Plan nor any Award shall create or be construed to create a trust or separate fund of any kind or a fiduciary relationship between the Company or any Affiliate, on the one hand, and a Participant or other person or entity, on the other hand. No provision of the Plan or any Award shall require the Company, for the purpose of satisfying any obligations under the Plan, to purchase assets or place any assets in a trust or other entity to which contributions are made or otherwise to segregate any assets, nor shall the Company maintain separate bank accounts, books, records or other evidence of the existence of a segregated or separately maintained or administered fund for such purposes. Participants shall have no rights under the Plan other than as unsecured general creditors of the Company, except that insofar as they may have become entitled to payment of additional compensation by performance of services, they shall have the same rights as other employees under general law.

**<u>ANNEX A</u>**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;p.<u>Reliance on Reports</u>. Each member of the Committee and each member of the Board shall be fully justified in acting or failing to act, as the case may be, and shall not be liable for having so acted or failed to act in good faith, in reliance upon any report made by the independent public accountant of the Company and its Affiliates and/or any other information furnished in connection with the Plan by any agent of the Company or the Committee or the Board, other than himself.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;q.<u>Relationship to Other Benefits</u>. No payment under the Plan shall be taken into account in determining any benefits under any pension, retirement, profit sharing, group insurance or other benefit plan of the Company except as otherwise specifically provided in such other plan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;r.<u>Governing Law</u>. The Plan shall be governed by and construed in accordance with the internal laws of the State of Delaware applicable to contracts made and performed wholly within the State of Delaware, without giving effect to the conflict of laws provisions thereof.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;s.<u>Arbitration</u>. All disputes and claims of any nature that a Participant (or such Participant's transferee or estate) may have against the Company arising out of or in any way related to the Plan or any Award Agreement shall be submitted to and resolved exclusively by binding arbitration conducted in Hamilton County, Ohio (or such other location as the parties thereto may agree) in accordance with the applicable rules of the American Arbitration Association then in effect, and the arbitration shall be heard and determined by a panel of three arbitrators in accordance with such rules (except that in the event of any inconsistency between such rules and this Section 14(s), the provisions of this Section 14(s) shall control). The arbitration panel may not modify the arbitration rules specified above without the prior written approval of all parties to the arbitration. Within ten (10) business days after the receipt of a written demand, each party shall designate one arbitrator, each of whom shall have experience involving complex business or legal matters, but shall not have any prior, existing or potential material business relationship with any party to the arbitration. The two arbitrators so designated shall select a third arbitrator, who shall preside over the arbitration, shall be similarly qualified as the two arbitrators and shall have no prior, existing or potential material business relationship with any party to the arbitration; provided that if the two arbitrators are unable to agree upon the selection of such third arbitrator, such third arbitrator shall be designated in accordance with the arbitration rules referred to above. The arbitrators will decide the dispute by majority decision, and the decision shall be rendered in writing and shall bear the signatures of the arbitrators and the party or parties who shall be charged therewith. The arbitration decision shall be rendered as soon as possible, but in any event not later than 120 days after the constitution of the arbitration panel. The arbitration decision shall be final and binding upon all parties to the arbitration. The parties hereto agree that judgment upon any award rendered by the arbitration panel may be entered in the United States District Court for the Southern District of Ohio or any court sitting in Hamilton County, Ohio. To the maximum extent permitted by law, the parties hereby irrevocably waive any right of appeal from any judgment rendered upon any such arbitration award in any such court. Notwithstanding the foregoing, any party may seek injunctive relief in any such court.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;t.<u>Severability</u>. If any provision of the Plan or any Award or Award Agreement is or becomes or is deemed to be invalid, illegal, or unenforceable in any jurisdiction or as to any person or entity or Award, or would disqualify the Plan or any Award under any law deemed applicable by the Committee, such provision shall be construed or deemed amended to conform to the applicable laws, or if it cannot be construed or deemed amended without, in the determination of the Committee, materially altering the intent of the Plan or the Award, such provision shall be construed or deemed stricken as to such jurisdiction, person or entity or Award and the remainder of the Plan and any such Award shall remain in full force and effect.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;u.<u>Statute of Limitations</u>. A Participant or any other person filing a claim for benefits under the Plan or an Award must file the claim within one (1) year of the date the Participant or other person knew or should have known of the facts giving rise to the claim. This one-year statute of limitations will apply in any forum where a Participant or any other person may file a claim and, unless the Company waives the time limit set forth above in its sole discretion, any claim not brought within the time period specified shall be waived and forever barred.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;v.<u>Obligations Binding on Successors</u>. The obligations of the Company under the Plan shall be binding upon any successor corporation or organization resulting from the merger, consolidation or other reorganization of the Company, or upon any successor corporation or organization succeeding to substantially all of the assets and business of the Company.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;w.<u>409A of the Code</u>. Subject to the terms of the Plan, the Committee may determine that all or a portion of any Award to a Participant, whether it is to be paid in cash, Common Stock or a combination thereof, shall be deferred or may, in its sole discretion, approve deferral elections made by Participants. Deferrals shall be for such periods and upon such terms as the Committee may determine in its sole discretion, which terms shall comply with Section 409A of the Code. Each Award granted under the Plan is intended to be either exempt from or in

------

**<u>ANNEX A</u>**

compliance with the requirements of Section 409A of the Code, and all provisions of this Plan shall be construed and interpreted in a manner consistent with the requirements for avoiding taxes or penalties under Section 409A of the Code. Each Participant is solely responsible and liable for the satisfaction of all taxes and penalties that may be imposed on or in respect of such Participant in connection with this Plan or any other plan maintained by the Company (including any taxes and penalties under Section 409A of the Code), and neither the Company nor any Affiliate shall have any obligation to indemnify or otherwise hold such Participant (or any beneficiary) harmless from any or all of such taxes or penalties. If a Participant is a Specified Employee at the time of the Participant's Separation from Service with the Company, then solely to the extent necessary to avoid the imposition of any additional tax under Section 409A of the Code, the commencement of any payments or benefits under an Award (which Award is subject to Section 409A of the Code and otherwise provides for the commencement of payments or benefits upon Separation from Service) shall be deferred until the date that is six months following the Participant's Separation from Service (or such other period as required to comply with Section 409A of the Code).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;x.<u>Clawback/Forfeiture</u>. Notwithstanding anything to the contrary contained herein, a Participant Agreement may provide that the Committee may in its sole discretion cancel such Award if the Participant, without the consent of the Company, while employed by or providing services to the Company or any Affiliate or after termination of such employment or service, violates a non-competition, non-solicitation or non-disclosure covenant or agreement or otherwise engages in activity that is in conflict with or adverse to the interest of the Company or any Affiliate, including fraud or conduct contributing to any financial restatements or irregularities, as determined by the Committee in its sole discretion. A Participant Agreement may also provide that if the Participant engages in any activity referred to in the preceding sentence, the Participant will forfeit any gain realized on the vesting or exercise of such Award, and must repay the gain to the Company. In addition, any Award shall be subject to forfeiture or repayment pursuant to the terms of any applicable compensation recoupment or recovery policy adopted by the Company, Committee or Board, as thereafter amended, including any policy adopted to comply with the rules of any national securities exchange on which the Company's Common Stock is traded or the Securities and Exchange Commission.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;y.<u>Section 16</u>. It is the intent of the Company that the Plan satisfy, and be interpreted in a manner that satisfies, the applicable requirements of Rule 16b-3 as promulgated under Section 16 of the Exchange Act so that Participants will be entitled to the benefit of Rule 16b-3, or any other rule promulgated under Section 16 of the Exchange Act, and will not be subject to short-swing liability under Section 16 of the Exchange Act. Accordingly, if the operation of any provision of the Plan would conflict with the intent expressed in this Section 14(w), such provision to the extent possible shall be interpreted and/or deemed amended so as to avoid such conflict.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;z.<u>Data Privacy</u>. As a condition of receipt of any Award, each Participant explicitly and unambiguously consents to the collection, use, and transfer, in electronic or other form, of personal data as described in this Section 14(z) by and among, as applicable, the Company and its Affiliates for the exclusive purpose of implementing, administering, and managing the Plan and Awards and the Participant's participation in the Plan. In furtherance of such implementation, administration, and management, the Company and its Affiliates may hold certain personal information about a Participant, including, but not limited to, the Participant's name, home address, telephone number, date of birth, social security or insurance number or other identification number, salary, nationality, job title(s), information regarding any securities of the Company or any of its Affiliates, and details of all Awards (the "<u>Data</u>"). In addition to transferring the Data amongst themselves as necessary for the purpose of implementation, administration, and management of the Plan, Awards, and the Participant's participation in the Plan, the Company and its Affiliates may each transfer the Data to any third parties assisting the Company in the implementation, administration, and management of the Plan and Awards and the Participant's participation in the Plan. Recipients of the Data may be located in the Participant's country or elsewhere, and the Participant's country and any given recipient's country may have different data privacy laws and protections. By accepting an Award, each Participant authorizes such recipients to receive, possess, use, retain, and transfer the Data, in electronic or other form, for the purposes of assisting the Company in the implementation, administration, and management of the Plan and Awards and the Participant's participation in the Plan. The Data related to a Participant will be held only as long as is necessary to implement, administer, and manage the Plan and Awards and the Participant's participation in the Plan. A Participant may, at any time, view the Data held by the Company with respect to such Participant, request additional information about the storage and processing of the Data with respect to such Participant, recommend any necessary corrections to the Data with respect to the Participant, or refuse or withdraw the consents herein in writing, in any case without cost, by contacting his or her local human resources representative. The Company may cancel the Participant's eligibility to participate in the Plan, and in the Committee's discretion, the Participant may forfeit any outstanding Awards if the Participant refuses or withdraws the consents described herein. For more information on the consequences of refusal to consent or withdrawal of consent, Participants may contact their local human resources representative.

aa.<u>Participants Outside of the United States</u>. The Committee may modify the terms of any Award under the Plan made to or held by a Participant who is then a resident, or is primarily employed or providing services, outside of the United States in any manner deemed by the Committee to be necessary or appropriate in order that such Award shall conform to laws, regulations, and customs of the country in which the Participant is then a resident or primarily employed or providing services, or so that the value and other benefits of the Award to the Participant, as affected by non–U.S. tax laws and other restrictions applicable as a result of the Participant's residence, employment, or providing services abroad, shall be comparable to the value of such Award to a Participant who is a resident, or is primarily employed or providing services, in the United States. An Award may be modified under this Section 14(aa) in a manner that is inconsistent with the express terms of the Plan, so long as such modifications will not contravene any applicable law or regulation or result in actual liability under Section 16(b) of the Exchange Act for the Participant whose Award is modified. Additionally, the Committee may adopt such procedures as are necessary or appropriate to permit participation in the Plan by Eligible Persons who are non–U.S. nationals or are primarily employed or providing services outside the United States.

ab.<u>Expenses; Gender; Titles and Headings</u>. The expenses of administering the Plan shall be borne by the Company and its Affiliates. Masculine pronouns and other words of masculine gender shall refer to both men and women. The titles and headings of the sections in the Plan are for convenience of reference only, and in the event of any conflict, the text of the Plan, rather than such titles or headings shall control.

To make such a change, the Participant must submit a new Enrollment Form authorizing the new rate of payroll deductions at least five (5) business days before the Purchase Date.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6.3.Automatic Re-enrollment. The deduction rate selected in the Enrollment Form shall remain in effect for subsequent Offering Periods unless the Participant (a) submits a new Enrollment Form authorizing a new level of payroll deductions in accordance with Section 6, (b) withdraws from the Plan in accordance with Section 10, or (c) terminates employment or otherwise becomes ineligible to participate in the Plan.

**7. <u>Grant of Option.</u>** 

On each Offering Date, each Participant in the applicable Offering Period shall be granted an option to purchase, on the Purchase Date, a number of shares of Common Stock determined by dividing the Participant's accumulated payroll deductions by the applicable Purchase Price; provided, however, that in no event shall any Participant purchase more than 2,500 shares of Common Stock during an Offering Period (subject to adjustment in accordance with Section 18 and the limitations set forth in Section 13 of the Plan).

**8. <u>Exercise of Option/Purchase of Shares.</u>**

A Participant's option to purchase shares of Common Stock will be exercised automatically on the Purchase Date of each Offering Period. The Participant's accumulated payroll deductions will be used to purchase the maximum number of whole shares that can be purchased with the amounts in the Participant's notional account. No fractional shares may be purchased but notional fractional shares of Common Stock will be allocated to the Participant's ESPP Share Account to be aggregated with other notional fractional shares of Common Stock on future Purchase Dates, subject to earlier withdrawal by the Participant in accordance with Section 10 or termination of employment in accordance with Section 11.

**9. <u>Transfer of Shares.</u>**

As soon as reasonably practicable after each Purchase Date, the Company will arrange for the delivery to each Participant of the shares of Common Stock purchased upon exercise of his or her option. The Committee may permit or require that the shares be deposited directly into an ESPP Share Account established in the name of the Participant with a Designated Broker and may require that the shares of Common Stock be retained with such Designated Broker for a specified period of time. Participants will not have any voting, dividend or other rights of a shareholder with respect to the shares of Common Stock subject to any option granted hereunder until such shares have been delivered pursuant to this Section 9.

**10. <u>Withdrawal.</u>**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;10.1.Withdrawal Procedure. A Participant may withdraw from an Offering by submitting to the Company a revised Enrollment Form indicating his or her election to withdraw at least five (5) days before the Purchase Date. The accumulated payroll deductions held on behalf of a Participant in his or her notional account (that have not been used to purchase shares of Common Stock) shall be paid to the Participant promptly following receipt of the Participant's Enrollment Form indicating his or her election to withdraw and the Participant's option shall be automatically terminated. If a Participant withdraws from

------

**<u>ANNEX B</u>**

an Offering Period, no payroll deductions will be made during any succeeding Offering Period, unless the Participant re-enrolls in accordance with Section 6 of the Plan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;10.2.Effect on Succeeding Offering Periods. A Participant's election to withdraw from an Offering Period will not have any effect upon his or her eligibility to participate in succeeding Offering Periods that commence following the completion of the Offering Period from which the Participant withdraws.

**11. <u>Termination of Employment; Change in Employment Status.</u>**

Upon termination of a Participant's employment for any reason, including death, disability or retirement, or a change in the Participant's employment status following which the Participant is no longer an Eligible Employee, which in either case occurs before the Purchase Date, the Participant will be deemed to have withdrawn from the Plan and the payroll deductions in the Participant's notional account (that have not been used to purchase shares of Common Stock) shall be returned to the Participant, or in the case of the Participant's death, to the person(s) entitled to such amounts under Section 17, and the Participant's option shall be automatically terminated

**12. <u>Interest.</u>**

No interest shall accrue on or be payable with respect to the payroll deductions of a Participant in the Plan.

**13. <u>Shares Reserved for Plan.</u>**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;13.1.Number of Shares. The maximum number of shares of Common Stock reserved as authorized for the grant of options under the Plan is 2,000,000 1,250,000 shares. If any right granted under the Plan shall for any reason terminate without having been exercised, the Common Stock not purchased under such right shall again become available for issuance under the Plan. In addition, any unused shares reserved under the AtriCure, Inc. 2008 Employee Stock Purchase Plan shall become available for issuance under this Plan and if any right granted under the AtriCure, Inc. 2008 Employee Stock Purchase Plan shall for any reason terminate without having been exercised, the Common Stock not purchased under such right shall become available for issuance under this Plan. The shares of Common Stock may be newly issued shares, treasury shares or shares acquired on the open market.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;13.2.Over-subscribed Offerings. The number of shares of Common Stock which a Participant may purchase in an Offering under the Plan may be reduced if the Offering is over-subscribed. No option granted under the Plan shall permit a Participant to purchase shares of Common Stock which, if added together with the total number of shares of Common Stock purchased by all other Participants in such Offering would exceed the total number of shares of Common Stock remaining available under the Plan. If the Committee determines that, on a particular Purchase Date, the number of shares of Common Stock with respect to which options are to be exercised exceeds the number of shares of Common Stock then available under the Plan, the Company shall make a pro rata allocation of the shares of Common Stock remaining available for purchase in as uniform a manner as practicable and as the Committee determines to be equitable.

**14. <u>Transferability.</u>**

No payroll deductions credited to a Participant, nor any rights with respect to the exercise of an option or any rights to receive Common Stock hereunder may be assigned, transferred, pledged or otherwise disposed of in any way (other than by will, the laws of descent and distribution, or as provided in Section 17 hereof) by the Participant. Any attempt to assign, transfer, pledge or otherwise dispose of such rights or amounts shall be without effect.

**15. <u>Application of Funds.</u>**

All payroll deductions received or held by the Company under the Plan may be used by the Company for any corporate purpose to the extent permitted by applicable law, and the Company shall not be required to segregate such payroll deductions or contributions.

**16. <u>Statements.</u>**

Participants will be provided with statements at least annually which shall set forth the contributions made by the Participant to the Plan, the Purchase Price of any shares of Common Stock purchased with accumulated funds, the number of shares of Common Stock purchased, and any payroll deduction amounts remaining in the Participant's notional account.

**17. <u>Designation of Beneficiary.</u>**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;17.1.A Participant may file, on forms supplied by the Committee, a written designation of beneficiary who is to receive any shares of Common Stock and cash in respect of any fractional shares of Common Stock, if

------

**<u>ANNEX B</u>**

any, from the Participant's ESPP Share Account under the Plan in the event of such Participant's death. In addition, a Participant may file a written designation of beneficiary who is to receive any cash withheld through payroll deductions and credited to the Participant's notional account in the event of the Participant's death prior to the Purchase Date of an Offering Period.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;17.2.Such designation of a beneficiary may be changed by the Participant at any time by written notice to the Company. In the event of the death of a Participant and in the absence of a beneficiary validly designated under the Plan who is living at the time of such Participant's death, the Company shall deliver such shares and/or cash to the executor or administrator of the estate of the Participant, or if no such executor or administrator has been appointed (to the knowledge of the Company), the Company, in its discretion, may deliver such shares and/or cash to the spouse or to any one or more dependents or relatives of the Participant, or if no spouse, dependent or relative is known to the Company, then to such other person as the Company may designate.

**18. <u>Adjustments Upon Changes in Capitalization; Dissolution or Liquidation; Change in Control.</u>**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;18.1.<u>Changes in Capitalization</u>. Subject to any required action by the shareholders of the Company, the number of shares of Common Stock which have been authorized for issuance under the Plan but not yet placed under option, the maximum number of shares each Participant may purchase during each Offering Period (pursuant to Section 7 hereof), as well as the price per share and the number of shares of Common Stock covered by each option under the Plan which has not yet been exercised shall be proportionately adjusted for any increase or decrease in the number of issued shares of Common Stock resulting from a stock split, reverse stock split, stock dividend, combination or reclassification of the Common Stock, or any other increase or decrease in the number of shares of Common Stock effected without receipt of consideration by the Company; provided, however, that conversion of any convertible securities of the Company shall not be deemed to have been "effected without receipt of consideration." Such adjustment shall be made by the Committee, whose determination in that respect shall be final, binding and conclusive. Except as expressly provided herein, no issuance by the Company of shares of stock of any class, or securities convertible into shares of stock of any class, shall affect, and no adjustment by reason thereof shall be made with respect to, the number or price of shares of Common Stock subject to an option.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;18.2.<u>Dissolution or Liquidation</u>. In the event of the proposed dissolution or liquidation of the Company, the Offering Period then in progress shall be shortened by setting a new Exercise Date (the "New Exercise Date"), and shall terminate immediately prior to the consummation of such proposed dissolution or liquidation, unless provided otherwise by the Committee. The New Exercise Date shall be before the effective date of the Company's proposed dissolution or liquidation. The Committee shall notify each Participant in writing, at least ten (10) business days prior to the New Exercise Date, that the Exercise Date for the Participant's option has been changed to the New Exercise Date and that the Participant's option shall be exercised automatically on the New Exercise Date, unless prior to such date the Participant has withdrawn from the Offering Period as provided in Section 10 hereof.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;18.3.<u>Merger or Change in Control</u>. In the event of a merger or Change in Control, the Offering Period with respect to each outstanding option will be shortened by setting a New Exercise Date and will end on the New Exercise Date. The New Exercise Date will occur before the date of the Company's proposed merger or Change in Control. The Committee will notify each Participant in writing, at least ten (10) business days prior to the New Exercise Date, that the Exercise Date for the Participant's option has been changed to the New Exercise Date and that the Participant's option will be exercised automatically on the New Exercise Date, unless prior to such date the Participant has withdrawn from the Offering Period as provided in Section 10 hereof.

**19. <u>General Provisions.</u>**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;19.1.Equal Rights and Privileges. Notwithstanding any provision of the Plan to the contrary and in accordance with Section 423 of the Code, all Eligible Employees who are granted options under the Plan shall have the same rights and privileges.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;19.2.No Right to Continued Service. Neither the Plan nor any compensation paid hereunder will confer on any Participant the right to continue as an Employee or in any other capacity.

------

**<u>ANNEX B</u>**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;19.3.Rights as Shareholder. A Participant will become a shareholder with respect to the shares of Common Stock that are purchased pursuant to options granted under the Plan when the shares are transferred to the Participant's ESPP Share Account. A Participant will have no rights as a shareholder with respect to shares of Common Stock for which an election to participate in an Offering Period has been made until such Participant becomes a shareholder as provided above.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;19.4.Successors and Assigns. The Plan shall be binding on the Company and its successors and assigns.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;19.5.Entire Plan. This Plan constitutes the entire plan with respect to the subject matter hereof and supersedes all prior plans with respect to the subject matter hereof.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;19.6.Compliance with Law. The obligations of the Company with respect to payments under the Plan are subject to compliance with all applicable laws and regulations. Common Stock shall not be issued with respect to an option granted under the Plan unless the exercise of such option and the issuance and delivery of the shares of Common Stock pursuant thereto shall comply with all applicable provisions of law, including, without limitation, the Securities Act, the Exchange Act, and the requirements of any stock exchange upon which the shares of Common Stock may then be listed.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;19.7.Notice of Disqualifying Dispositions. Each Participant shall give the Company prompt written notice of any disposition or other transfer of shares of Common Stock acquired pursuant to the exercise of an option acquired under the Plan, if such disposition or transfer is made within two years after the Offering Date or within one year after the Purchase Date.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;19.8.Term of Plan. The Plan shall become effective on the Effective Date and, unless terminated earlier pursuant to Section 19.9, shall have a term of ten (10) years.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;19.9.Amendment or Termination. The Committee may, in its sole discretion, amend, suspend or terminate the Plan at any time and for any reason. If the Plan is terminated, the Committee may elect to terminate all outstanding Offering Periods either immediately or once shares of Common Stock have been purchased on the next Purchase Date (which may, in the discretion of the Committee, be accelerated) or permit Offering Periods to expire in accordance with their terms (and subject to any adjustment in accordance with Section 18). If any Offering Period is terminated before its scheduled expiration, all amounts that have not been used to purchase shares of Common Stock will be returned to Participants (without interest, except as otherwise required by law) as soon as administratively practicable.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;19.10.Applicable Law. The laws of the State of Delaware shall govern all questions concerning the construction, validity and interpretation of the Plan, without regard to such state's conflict of law rules.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;19.11.Shareholder Approval. The Plan shall be subject to approval by the shareholders of the Company within twelve (12) months before or after the date the Plan is adopted by the Board.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;19.12.Section 423. The Plan is intended to qualify as an "employee stock purchase plan" under Section 423 of the Code. Any provision of the Plan that is inconsistent with Section 423 of the Code shall be reformed to comply with Section 423 of the Code.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;19.13.Withholding. To the extent required by applicable Federal, state or local law, a Participant must make arrangements satisfactory to the Company for the payment of any withholding or similar tax obligations that arise in connection with the Plan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;19.14.Severability. If any provision of the Plan shall for any reason be held to be invalid or unenforceable, such invalidity or unenforceability shall not affect any other provision hereof, and the Plan shall be construed as if such invalid or unenforceable provision were omitted.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;19.15.Headings. The headings of sections herein are included solely for convenience and shall not affect the meaning of any of the provisions of the Plan.

**<u>ANNEX C</u>**

**<u>Use of Non-GAAP Financial Measures</u>**

To supplement AtriCure's condensed consolidated financial statements prepared in accordance with accounting principles generally accepted in the United States of America, or GAAP, AtriCure uses certain non-GAAP financial measures in this proxy statement as supplemental financial metrics.

Adjusted EBITDA is calculated as net income (loss) before other income/expense (including interest), income tax expense, depreciation and amortization expense, share-based compensation expense, and non-recurring charges that are not reflective of the operational results of the Company's core business and may affect comparability of results period-over-period. Non-recurring charges include acquisition costs, acquired-in-process research and development (IPR&D) and related milestone payments arising from asset acquisitions, legal settlement costs, impairment of intangible assets and change in fair value of contingent consideration liabilities. Management believes in order to properly understand short-term and long-term financial trends, investors may wish to consider the impact of these excluded items in addition to GAAP measures. The excluded items vary in frequency and/or impact on our continuing results of operations and management believes that the excluded items are typically not reflective of our ongoing core business operations and financial condition. Further, management uses adjusted EBITDA for both strategic and annual operating planning. A reconciliation of adjusted EBITDA reported to the most comparable GAAP measure for the respective periods can be found below.

The non-GAAP financial measures used by AtriCure may not be the same or calculated in the same manner as those used and calculated by other companies. Non-GAAP financial measures have limitations as analytical tools and should not be considered in isolation or as a substitute for AtriCure's financial results prepared and reported in accordance with GAAP.
