This Proxy Summary provides general information about Proto Labs, Inc. (the “Company”) and highlights certain information contained elsewhere in this Proxy Statement. As it is only a summary, please refer to the entire Proxy Statement and the Annual Report on Form 10-K for the year ended December 31, 2022 before you vote.

2022 HIGHLIGHTS
Like many companies, Proto Labs faced internal and external disruptions to our business in 2022. Throughout the year, we worked to overcome these challenges, and we achieved our strategic goals to enable us to drive future growth. Despite the obstacles of the macroeconomic environment and internal challenges, our business strategy and market opportunity remain strong. 2022 was highlighted by low double digit organic revenue growth in our CNC machining and 3D printing services and we generated $48.5 million in revenue from our Hubs business. In 2022, we also made significant progress on the integrated Proto Labs and Hubs offer, allowing our customers to realize the benefits of a unique integrated CNC offer. We established an important platform that will allow us to prove the value of our comprehensive offer strategy.

CORPORATE RESPONSIBILITY AND SUSTAINABILITY HIGHLIGHTS
Our corporate responsibility and sustainability practices are built on a foundation of shared fundamental values of teamwork, trust and achievement, and help us to deliver strong financial results that create value for our Company and our shareholders in a way that respects our communities and the environments in which we operate. The Company's three core values are embodied in everything we do.

• | Teamwork – We are dedicated to the idea that a diversity of minds is better than one. Through open communication, we strive to collaborate with and include all of our colleagues to maximize our creativity and to make our good ideas great. We respect each other’s opinions. We help colleagues who are struggling to improve, so our success is everyone’s success.

• | Trust – Our integrity is built on honest answers to our customers and colleagues. It is okay to make mistakes if we use them to learn. We navigate difficult situations with compassion. The success of our Company depends on the success of our people.

• | Achievement – Speed and innovation are the cornerstones of our success. We are committed to being a solution for getting things done quickly and sustainably and a catalyst for great ideas for our shareholders, customers, the environment and each other. We are responsible for our performance, our results and our future.

ENVIRONMENTAL, SOCIAL AND GOVERNANCE
In 2021, our board of directors, executives and leaders throughout the organization focused to identify our top environmental, social and governance (ESG) priorities for 2022 and beyond. In 2022, for each of our top priorities, we focused on: (1) identifying data, measures and metrics, (2) assessing our current performance, (3) setting both short- and long-term goals for each of our top priorities, and (4) beginning to execute on our plans for each of these areas. The figure below shows the results of our ESG priority setting initiative in terms of both importance to stakeholders and our Company’s success.

TABLE OF CONTENTS

Our environmental key priorities include:

• | Environmental compliance

• | Energy use reduction

• | Waste management/recycling

In 2022, one of our environmental objectives was to define our key priorities and focus areas. Once our key priorities were defined, we implemented cross functional teams to begin collecting base data related to energy use and waste management/recycling.
Our social key priorities include:

• | Ethics and integrity

• | Employee health and well being

• | Diversity, equity and inclusion

In 2022, we defined our key priorities and focus areas. We established goals and initiatives specific to each key area, determined whether goals were global or regional in nature and established action plans to drive improvement.
Our governance key priorities include:

• | Ethics, compliance and transparency

• | Regulatory management

• | Risk and crisis management

In 2022, we evolved our formal enterprise risk management program, which included input from our board of directors and various levels of company leadership. Our program includes annual formal enterprise and fraud risk assessments with continuous feedback throughout the year as we evaluate the operating environment. The results of the enterprise risk management program will be used to drive governance key priorities and company strategy in 2023 and beyond. In addition, we set regulatory management goals around International Traffic in Arms Regulation and global export compliance and established enhanced decision authority and signatory matrices to drive governance oversight and compliance.

• | Digital Manufacturing Drives Sustainability

As a digital manufacturer, we are able to assist our customers as they focus on materials management, operational productivity and on-demand solutions. Digital manufacturing is a solution our customers can deploy to reduce product waste by iterating part designs virtually, on a digital twin model, before any actual production begins. With on-demand production of parts, there is also reduced reliance on storage facilities since inventory is virtual – the parts you need, when you need them. Our on-demand manufacturing model also helps customers with end-of-life planning for products, reducing the need for ordering excess parts with shifting market demand.
When paired with a robust e-commerce platform, digital manufacturing can also increase efficiencies in material selection and usage, the procurement process, and accelerating innovation. Furthermore, reducing scrap rate requires monitoring systems that enable automated process cycle sheet generation, ensuring run-to-run repeatability and reducing operator error. This kind of monitoring system can improve consistency in part production and reduce scrap costs, especially in injection molding. We believe sustainability in product development, and in manufacturing, is the future and we will continue to support our customers in their own sustainability journeys.

• | Environmental Initiatives

We are committed to having a positive impact on the environment. In 2022, we hosted InspirON in Europe, an online knowledge sharing event to focus on what design engineers need to consider when developing sustainable products for manufacturing. The event was designed to provide insight into designing more sustainable products and to explore how design can help make the manufacturing process greener and more efficient. The event covered topics ranging from: sustainable material selection, to the role that digital manufacturing and industry 4.0 will play, to how to develop and optimize a sustainable supply chain.

TABLE OF CONTENTS

In 2021, we were awarded a Manufacturing Leadership Award from the National Association of Manufacturers (NAM) in the Sustainability Leadership category. This category recognizes companies embracing manufacturing processes that are non-polluting, conserve energy and natural resources, and are economically sound and safe for employees, communities, and consumers. In 2020, we installed nearly 1,900 solar panels on the roof of our facility in Plymouth, MN, one of our larger manufacturing facilities. The solar array covers nearly 20 percent of our energy use in Plymouth, MN and offsets the equivalent of 1.3 million pounds of CO2 and preserves 775 acres of forest annually.
We strive to maximize recycling in both our manufacturing and office facilities. In our manufacturing facilities, we recycle metal, plastic and water used throughout the manufacturing processes. Finally, the Green Team, an employee-led organization, educates our employees on how they can positively impact the environment, both at work and at home.

• | Diversity, Equity and Inclusion

At Proto Labs, diversity, equity and inclusion matters. We are committed to nurturing a culture where we celebrate diversity, equity and inclusivity as a way of life. Our diversity and inclusion efforts start at the top with our board regularly reviewing initiatives. Our Diversity, Equity and Inclusion (DEI) Leadership Council was established to promote honest conversations, influence best practices and educate our employees. Our DEI Leadership Council members are employee representatives chosen from various functions and locations to work directly with our leadership team to drive change in our work environment. We also require certain employees to participate in annual unconscious bias training to further foster a work environment of fairness and sensitivity. As we continue to grow, we will continue to emphasize employee safety and having an inclusive work environment as top priorities. Our goal is to build diverse teams throughout the global organization and be a role model for the communities where we work and live. Uniqueness defines us as a company, from our custom products to our employees. Our pledge is to promote a global culture that invites, recognizes and embraces each individuals contributions to make a stronger “US”.

• | Workforce Demographics

As of December 31, 2022, we had 2,568 full-time employees, including 1,787 full-time employees in the United States, 777 full-time employees in Europe and 4 full-time employees in Japan. We also regularly use independent contractors and other temporary employees across the organization to augment our regular staff. We believe that our future success will depend in part on our continued ability to attract, hire and retain qualified, diverse and inclusive personnel.
We are an equal opportunity employer, and we believe that a diverse workforce made up of people with different ideas, strengths, interests and cultural backgrounds drives employee and business success. Our workforce is composed of a diverse group of engineers, technicians and business professionals from around the world and every walk of life.
We believe our employees are critical to our success and continually seek employee feedback to enhance employee engagement. In 2022, our attrition rates were higher than in previous years. Our attrition rates were 21.8% and 23.1% in the United States and Europe, respectively.

• | Compensation and Benefits

We believe our success depends in large measure on our ability to attract, retain and motivate a broad range of employees to be successful in a dynamic and changing business environment, and that a competitive compensation program is essential. In determining employee compensation, our executive leadership team reviews and considers several factors, including individual and corporate performance, input from managers, competitor market data from third party compensation surveys, our compensation philosophy and key principles, and the leadership’s collective experience and knowledge. Annually, our executive leadership team reviews input from managers throughout our organization, including recommendations as to compensation levels that the managers believe are commensurate with an individual’s job performance, skills, experience, qualifications, criticality to our Company and development/career opportunities. We also award long-term equity-based compensation to high performing employees and managers who have the greatest impact on the creation of shareholder value to further align the interests of our employees and shareholders.

In 2022 and 2021, employees spent an average of 36 and 14 hours, respectively, per employee in training sessions.

• | Supply Chain

We are committed to conducting our business in accordance with the highest ethical standards and in compliance with all applicable laws, rules and regulations.

OUR COMPENSATION APPROACH
We believe our success depends in large measure on our ability to attract, retain and motivate a talented senior management team to effectively lead our Company in a dynamic and changing business environment, and that a competitive executive compensation program is essential to that effort. We believe that our executive compensation program should support our short- and long-term strategic and operational objectives, and reward corporate and individual performance that contributes to creating value for our shareholders.
Consistent with this philosophy, and past practice, the majority of our named executive officers’ 2022 summary annual compensation is considered "at risk".

PROXY STATEMENT
The board of directors of Proto Labs, Inc. is soliciting proxies for use at the Annual Meeting to be held on May 17, 2023, and at any adjournment or postponement of the meeting.
QUESTIONS AND ANSWERS ABOUT THE ANNUAL MEETING AND VOTING

Q: | Who can vote?

A: | You can vote if you were a shareholder at the close of business on the record date of March 22, 2023 (the “Record Date”). There were a total of 26,202,723 shares of our common stock outstanding on the Record Date. The Notice of Internet Availability of Proxy Materials (the “Notice”), notice of Annual Meeting, this Proxy Statement and accompanying proxy card and the Annual Report on Form 10-K for 2022 were first mailed or made available to you beginning on or about April 4, 2023. This Proxy Statement summarizes the information you need to vote at the Annual Meeting.

Q: | Who can attend the Annual Meeting?

A: | This year, the 2023 Annual Meeting will once again be conducted exclusively virtually via live webcast at www.virtualshareholdermeeting.com/PRLB2023 (the “Annual Meeting Website”). All shareholders, regardless of size, resources or physical location, eligible to attend the Annual Meeting will be able to participate via webcast and will be able to communicate with us and ask questions before and during the Annual Meeting. All shareholders as of the Record Date, or their duly appointed proxies, may attend the Annual Meeting. If you hold your shares in street name, then you must request a legal proxy from your broker or nominee to attend and vote at the Annual Meeting.

Q: | What am I voting on?

A: | You are voting on:

• | Election of eight nominees as directors to hold office until the next Annual Meeting of Shareholders or until their successors are duly elected.

• | Ratification of the selection of Ernst & Young LLP as our independent registered public accounting firm for fiscal 2023.

• | Approval on an advisory basis of the compensation of our officers disclosed in this Proxy Statement, which we refer to as a “say-on-pay” vote.

• | Approval of an amendment to the Proto Labs, Inc. 2022 Long-Term Incentive Plan.

• | A shareholder proposal entitled Fair Elections, if properly presented at the Annual Meeting.

Q: | How does the board of directors recommend I vote on the proposals?

A: | The board is soliciting your proxy and recommends you vote:

• | FOR each of the director nominees;

• | FOR the ratification of the selection of Ernst & Young LLP as our independent registered public accounting firm for fiscal 2023;

• | FOR the say-on-pay proposal;

• | FOR the approval of an amendment to the Proto Labs, Inc. 2022 Long-Term Incentive Plan; and

• | AGAINST the shareholder proposal entitled Fair Elections, if properly presented at the Annual Meeting.

Q: | Why did I receive a notice in the mail regarding the Internet availability of proxy materials instead of a paper copy of the proxy materials?

A: | “Notice and Access” rules adopted by the United States Securities and Exchange Commission (the “SEC”) permit us to furnish proxy materials, including this Proxy Statement and our Annual Report on Form 10-K for 2022, to our shareholders by providing access to such documents on the Internet instead of mailing printed copies. Shareholders will not receive printed copies of the proxy materials unless they request them. Instead, the Notice instructs as to how you may access and review all of the proxy materials on the Internet.

8|

TABLE OF CONTENTS

The Notice also instructs as to how you may submit your proxy via the Internet. If you would like to receive a paper or email copy of our proxy materials, you should follow the instructions for requesting such materials in the Notice. Any request to receive proxy materials by mail will remain in effect until you revoke it.

Q: | How many shares must be voted to approve each proposal?

A: | Quorum. A majority of the shares entitled to vote, represented in person or by proxy, is necessary to constitute a quorum for the transaction of business at the Annual Meeting. As of the Record Date, 26,202,723 shares of our common stock were issued and outstanding. A majority of those shares will constitute a quorum for the purpose of electing directors and adopting proposals at the Annual Meeting. If you submit a valid proxy or attend the Annual Meeting, your shares will be counted to determine whether there is a quorum.

Vote Required. Generally, directors are elected by a majority of the votes cast with respect to the director, meaning that the votes cast “for” a director must exceed the votes cast “against” the director. However, in a contested election of directors in which the number of nominees exceeds the number of directors to be elected, the directors are elected by a plurality of the votes present in person or by proxy at the meeting. The election of directors at the Annual Meeting will be an uncontested election, and therefore directors will be elected by a majority of the votes cast with respect to the director.
The proposal to ratify the selection of our independent registered public accounting firm must be approved by the affirmative vote of the greater of (a) a majority of the shares of our common stock present online or by proxy at the Annual Meeting and entitled to vote or (b) a majority of the minimum number of shares of common stock entitled to vote that would constitute a quorum. For the advisory say-on-pay vote, there is no minimum approval necessary since it is advisory. However, if the advisory say-on-pay resolution in this Proxy Statement receives more votes “for” than “against,” then it will be deemed to be approved. The say-on-pay vote is advisory and is not binding on the board of directors. The proposal to approve an amendment to the Proto Labs, Inc. 2022 Long-Term Incentive Plan must be approved by the affirmative vote of the greater of (a) a majority of the shares of our common stock present online or by proxy at the Annual Meeting and entitled to vote or (b) a majority of the minimum number of shares of common stock entitled to vote that would constitute a quorum. For the shareholder proposal, if properly presented at the Annual Meeting, it must be approved by the affirmative vote of the greater of (a) a majority of the shares of our common stock present online or by proxy at the Annual Meeting and entitled to vote or (b) a majority of the minimum number of shares of common stock entitled to vote that would constitute a quorum.

Q: | What is the effect of broker non-votes and abstentions?

A: | A “broker non-vote” occurs when a nominee holding shares for a beneficial owner does not vote on a particular proposal because the nominee does not have or does not exercise discretionary voting power with respect to that item and has not received voting instructions from the beneficial owner. If a broker returns a “non-vote” proxy indicating a lack of authority to vote on a proposal, then the shares covered by such a “non-vote” proxy will be deemed present at the Annual Meeting for purposes of determining a quorum, but not present for purposes of calculating the vote with respect to any non-discretionary proposals. Nominees will not have discretionary voting power with respect to any matter to be voted upon at the Annual Meeting, other than the ratification of the selection of our independent registered public accounting firm. Broker non-votes will have no effect on any of the proposals.

A properly executed proxy marked “ABSTAIN” with respect to a proposal will be counted for purposes of determining whether there is a quorum and will be considered present in person or by proxy and entitled to vote, but will not be deemed to have been voted in favor of such proposal. Abstentions will have no effect on the voting for the election of directors or approval of the advisory say-on-pay resolution. Abstentions will have the same effect as voting against the proposal to ratify the selection of our independent registered public accounting firm, the proposal to approve an amendment to the Proto Labs, Inc. 2022 Long-Term Incentive Plan, the shareholder proposal entitled Fair Elections, and any other item properly presented at the Annual Meeting or any adjournments or postponements thereof.

Q: | How will the proxies vote on any other business brought up at the Annual Meeting?

A: | By submitting your proxy, you authorize the proxies to use their judgment to determine how to vote on any other matter brought before the Annual Meeting, or any adjournments or postponements thereof. We do not know of any other business to be considered at the Annual Meeting. The proxies’ authority to vote according to their judgment applies only to shares you own as the shareholder of record.

• | Internet. You may vote by going to the web address www.proxyvote.com 24-hours a day, seven days a week, until 11:59 p.m. Eastern Time on May 16, 2023 and following the instructions for Internet voting shown on your Notice or proxy card.

• | Telephone. If you requested printed proxy materials and you received a paper copy of the proxy card, you may vote by dialing 1-800-690-6903 24-hours a day, seven days a week, until 11:59 p.m. Eastern Time on May 16, 2023 and following the instructions for telephone voting shown on your proxy card.

If you vote by Internet or telephone, please do not mail your proxy card.

• | Virtually at the Annual Meeting Website. If you are a shareholder whose shares are registered in your name, you may vote virtually via live webcast during the Annual Meeting.

If your shares are held on account at a brokerage firm, bank or similar organization, you will receive voting instructions from your bank, broker or other nominee describing how to vote your shares. You must follow those instructions to vote your shares. You will receive the Notice that instructs how to access our proxy materials on the Internet and vote your shares via the Internet. It also instructs how to request a paper copy of our proxy materials. If you hold your shares in street name and want to vote virtually during the Annual Meeting, then you must obtain a legal proxy from your broker or nominee.
Proxies that are voted via the Internet or by telephone in accordance with the voting instructions provided, and proxy cards that are properly signed, dated and returned, will be voted in the manner specified.

Q: | Can I vote my shares by filling out and returning the Notice?

A: | No. The Notice identifies the items to be voted on at the Annual Meeting, but you cannot vote by marking the Notice and returning it. The Notice provides instructions on how to vote by Internet, by requesting and returning a paper proxy card or voting instruction card, or by voting at the Annual Meeting.

Q: | Can I revoke or change my vote?

A: | You can revoke your proxy at any time before it is voted at the Annual Meeting by:

• | submitting a new proxy with a more recent date than that of the prior proxy given before 11:59 p.m. Eastern Time on May 16, 2023 by (1) following the Internet voting instructions or (2) following the telephone voting instructions;

• | completing, signing, dating and returning a new proxy card to us, which must be received by us before the time of the Annual Meeting; or

• | participating in the virtual Annual Meeting and revoking the proxy by voting those shares when joining the meeting.

Joining the Annual Meeting will not by itself revoke a previously granted proxy. Unless you decide to vote your shares virtually at the Annual Meeting, you should revoke your prior proxy in the same way you initially submitted it—that is, by Internet, telephone or mail.

Q: | Who will count the votes?

A: | Broadridge Financial Solutions, Inc., our independent proxy tabulator, will count the votes. Daniel Schumacher, our Chief Financial Officer, will act as inspector of election for the Annual Meeting.

Q: | Is my vote confidential?

A: | All proxies and all vote tabulations that identify an individual shareholder are confidential. Your vote will not be disclosed except:

• | to allow Broadridge Financial Solutions, Inc. to tabulate the vote;

• | to allow Daniel Schumacher to certify the results of the vote; and

• | to meet applicable legal requirements.

TABLE OF CONTENTS

Q: | What shares are included on my proxy?

A: | Your proxy will represent all shares registered to your account.

Q: | What happens if I don’t vote shares that I own?

A: | For shares registered in your name. If you do not vote shares that are registered in your name by voting online at the Annual Meeting or by proxy through the Internet, telephone or mail, your shares will not be counted in determining the presence of a quorum or in determining the outcome of the vote on the proposals presented at the Annual Meeting.

For shares held in street name. If you hold shares through a broker, you will receive voting instructions from your broker. If you do not submit voting instructions to your broker and your broker does not have discretion to vote your shares on a particular matter, then your shares will not be counted in determining the outcome of the vote on that matter at the Annual Meeting. See “What is the effect of broker non-votes and abstentions?” as described above. Your broker will not have discretion to vote your shares for any matter to be voted upon at the Annual Meeting other than the ratification of the selection of our independent registered public accounting firm. Accordingly, it is important that you provide voting instructions to your broker for the matters to be voted upon at the Annual Meeting.

Q: | What if I do not specify how I want my shares voted?

A: | If you are a registered shareholder and submit a signed proxy card or submit your proxy by Internet or telephone but do not specify how you want to vote your shares on a particular matter, we will vote your shares as follows:

• | FOR each of the director nominees;

• | FOR the ratification of the selection of Ernst & Young LLP as our independent registered public accounting firm for fiscal 2023;

• | FOR the say-on-pay proposal;

• | FOR the approval of an amendment to the Proto Labs, Inc. 2022 Long-Term Incentive Plan; and

• | AGAINST the shareholder proposal entitled Fair Elections, if properly presented at the Annual Meeting.

If any matters not described in this Proxy Statement are properly presented at the Annual Meeting, the proxy holders will use their own judgment to determine how to vote your shares. If the Annual Meeting is adjourned or postponed, the proxy holders can vote your shares on the new meeting date as well, unless you have revoked your proxy instructions, as described under “Can I revoke or change my vote?”
If you hold shares through a broker, please see above under “What happens if I don’t vote shares that I own?”

Q: | What does it mean if I get more than one Notice or proxy card?

A: | Your shares are probably registered in more than one account. You should provide voting instructions for all Notices and proxy cards you receive.

Q: | How many votes can I cast?

A: | You are entitled to one vote per share on all matters presented at the Annual Meeting or any adjournment or postponement thereof. There is no cumulative voting.

Q: | When are shareholder proposals and nominees due for the 2024 Annual Meeting of Shareholders?

Q: | What is “householding”?

A: | We may send a single Notice, as well as other shareholder communications, to any household at which two or more shareholders reside unless we receive other instruction from you. This practice, known as “householding,” is designed to reduce duplicate mailings and printing and postage costs, and conserve natural resources. If your Notice is being householded and you wish to receive multiple copies of the Notice, or if you are receiving multiple copies and would like to receive a single copy, or if you would like to opt out of this practice for future mailings, you may contact:

Q: | How is this proxy solicitation being conducted?

A: | We will pay for the cost of soliciting proxies and we will reimburse brokerage houses and other custodians, nominees and fiduciaries for their reasonable out-of-pocket expenses for forwarding proxy and solicitation materials to our shareholders.

TABLE OF CONTENTS

CORPORATE GOVERNANCE
Board Leadership Structure
Archie Black leads our board of directors in his role as Chairman. Our board of directors believes that its leadership structure is appropriate for our Company in light of the importance of maintaining independent board leadership and engagement.
As Chairman, Mr. Black:

• | presides at all meetings of the board of directors, including executive sessions of the independent directors;

• | conducts the annual performance review of the Chief Executive Officer, with input from the other independent directors;

• | sets the board agenda and frequency of meetings, in consultation with the committee chairs as applicable; and

• | has the authority to convene meetings of the independent directors at every meeting.

Risk Oversight
Our management is responsible for defining the various risks facing our Company, formulating risk management policies and procedures, and managing our risk exposures on a day-to-day basis. The board’s responsibility is to monitor our risk management processes by using board meetings, management presentations and other opportunities to educate itself concerning our material risks and evaluating whether management has reasonable controls in place to address the material risks; the board is not responsible, however, for defining or managing our various risks. The full board is responsible for monitoring management’s responsibility in the area of risk oversight. In addition, the audit committee and compensation committee have risk oversight responsibilities in their respective areas of focus, on which they report to the full board. Management reports from time to time to the full board, audit committee and compensation committee on risk management. The board focuses on the material risks facing our Company, including operational, credit, liquidity, legal and cybersecurity risks, to assess whether management has reasonable controls in place to address these risks.
Nominating Process and Board Diversity
In consultation with other members of the board of directors, the nominating and governance committee is responsible for identifying individuals who it considers qualified to become board members. The nominating and governance committee will screen potential director candidates, including those recommended by shareholders, and recommend to the board of directors suitable nominees for the election to the board of directors. The nominating and governance committee uses a variety of methods for identifying and evaluating nominees for directors. The nominating and governance committee regularly assesses the appropriate size and composition of the board of directors, the needs of the board of directors and the respective committees of the board of directors, and the qualifications of candidates in light of these needs. Candidates may come to the attention of the nominating and governance committee through shareholders, management, current members of the board of directors, or search firms. The evaluation of these candidates may be based solely upon information provided to the committee or may include discussions with persons familiar with the candidate, an interview of the candidate or other actions the committee deems appropriate, including the use of third parties to review candidates.
In considering whether to recommend an individual for election to the board, the nominating and governance committee considers, as required by the corporate governance guidelines and its charter, the board’s overall balance of diversity of perspectives, backgrounds, and experiences, although it does not have a formal policy regarding the consideration of diversity of board members. The nominating and governance committee views diversity expansively and considers, among other things, breadth and depth of relevant business and board skills and experiences, educational background, employment experience and leadership performance as well as those intangible factors that it deems appropriate to develop a heterogeneous and cohesive board, such as integrity, achievements, judgment, intelligence, personal character, the interplay of the candidate’s relevant experience with the experience of other board members, the willingness of the candidate to devote sufficient time to board duties, and likelihood that he or she will be willing and able to serve on the board for an extended period of time.
The nominating and governance committee will consider a recommendation by a shareholder of a candidate for election as a Proto Labs director. Shareholders who wish to recommend individuals for consideration by the nominating and governance committee to become nominees for election to the board may do so by submitting a written recommendation to our Secretary. Recommendations must be received by the Secretary within the timelines specified in our Bylaws to be considered by the nominating and governance committee for possible

nomination at our Annual Meeting of Shareholders the following year. Our Bylaws provide that such notice should be received no less than 90 days prior to the first anniversary of the preceding year’s Annual Meeting, except in certain circumstances. All recommendations must contain the information required in our Bylaws and corporate governance guidelines, including, among other things, the identification of the nominee, a written consent by the recommended individual to agree to be named in our proxy statement and to serve as director if elected, and the name and address of the shareholder submitting the nomination. Shareholders may also have the opportunity to include nominees in our proxy statement by complying with the requirements set forth in Section 2.17 of our Bylaws. Recommendations must be received by the Secretary within the timeframes noted under “Submission of Shareholder Proposals and Nominations.”
Proxy Access
Our Bylaws include a “proxy access” provision for director nominations under which eligible shareholders may nominate candidates for election to our board and inclusion in our proxy statement. The “proxy access” provision permits an eligible shareholder, or an eligible group of up to 20 shareholders, owning continuously for at least three years shares of our Company representing an aggregate of at least three percent of the voting power entitled to vote in the election of directors, to nominate and include in our annual meeting proxy materials director nominees not to exceed the greater of (i) two or (ii) 25 percent of the number of directors then serving on our board, or, if such amount is not a whole number, the closest whole number below 25 percent, but not less than two. Such nominations are subject to certain eligibility, procedural, and disclosure requirements set forth in section 2.17 of our Bylaws, including the requirement that our Company must receive notice of such nominations not less than 120 calendar days prior to the anniversary date of the prior year’s annual proxy materials mailing, except as otherwise provided in section 2.17 of our Bylaws. Section 2.17 of our Bylaws provides the exclusive method for a shareholder to include nominees for election to the board of directors in the Company’s proxy materials, other than with respect to Rule 14a-19 to the extent applicable with respect to the form of proxies.
Director Independence
Our board of directors has reviewed the materiality of any relationship that each of our directors has with us, either directly or indirectly. Based on this review, our board has determined that, with the exception of Dr. Robert Bodor, our Chief Executive Officer, all of the directors and director nominees are “independent directors” as defined by Section 303A.02 of the New York Stock Exchange Listed Company Manual.
Code of Ethics and Business Conduct
We have adopted a code of ethics and business conduct relating to the conduct of our business by our employees, officers and directors, which is posted on our website at www.protolabs.com under the investor relations section. Annually, our employees are required to complete code of conduct and business ethics training. We plan to post to our website at the address described above any future amendments or waivers to our code of ethics and business conduct.
Communications with the Board and Corporate Governance Guidelines
Under our Corporate Governance Guidelines, a process has been established by which shareholders and other interested parties may communicate with members of the board of directors. Any shareholder or other interested party who desires to communicate with the board, individually or as a group, may do so by writing to the intended member or members of the board, c/o Secretary, Proto Labs, Inc., 5540 Pioneer Creek Drive, Maple Plain, Minnesota 55359. A copy of our Corporate Governance Guidelines is available at www.protolabs.com under the investor relations section.
All communications received in accordance with these procedures will initially be received and processed by the office of our Secretary to determine that the communication is a message to one or more of our directors and will be relayed to the appropriate director or directors. The director or directors who receive any such communication will have discretion to determine whether the subject matter of the communication should be brought to the attention of the full board or one or more of its committees and whether any response to the person sending the communication is appropriate.
Board Meetings
During 2022, the full board of directors met five times in person and held seven meetings via videoconference. Five of the meetings were preceded and/or followed by an executive session of the independent directors, chaired by Mr. Black or the acting chair of the meeting. Each of our then-serving directors attended at least 75% percent of the meetings of the board and any committee on which they served in 2022. We do not maintain a formal policy regarding the board’s attendance at annual shareholder meetings; however, board members are expected to regularly attend all board meetings and meetings of the committees on which they serve and are encouraged to make every effort to attend the Annual Meeting of Shareholders. All of our then-serving directors attended the 2022 Annual Meeting of Shareholders.

Summary of Proto Labs’ Performance
Like many companies, Proto Labs faced internal and external disruptions to our business in 2022. Throughout the year, we worked to overcome these challenges, and we achieved our strategic goals to enable us to drive future growth. Despite the obstacles of the macroeconomic environment and internal challenges, our business strategy and market opportunity remain strong. 2022 was highlighted by low double digit organic revenue growth in our CNC machining and 3D printing services and we generated $48.5 million in revenue from our Hubs business. In 2022, we also made significant progress on the integrated Proto Labs and Hubs offer, allowing our customers to realize the benefits of a unique integrated CNC offer. We established an important platform that will allow us to prove the value of our comprehensive offer strategy.

​ | Revenue | ​ | ​ | Cash Generation | ​ | ​ | Strategic | ​
​ | $488.4m Revenue increased to $488.4 million in 2022 compared with $488.1 million in 2021. | ​ | ​ | $62.1m Cash generated from operations during the year totaled $62.1 million as compared to $55.2 million in 2021. | ​ | ​ | Hubs Integration Significant progress on the integrated Proto Labs and Hubs offer, allowing our customers to realize the benefits of a unique integrated CNC offer. | ​

Shareholder Value Creation
Although our total shareholder return (“TSR”) was not as strong as our peer group and reference indices at the end of 2022, it has been historically very strong, exceeding that of the peer group, the S&P 500 and the Russell 2000 Growth Index from our IPO through 2020. While our TSR has declined in 2021 and 2022 relative to these measures, our board of directors and senior management team believe this is temporary and are taking actions designed to drive profitable revenue growth and ultimately shareholder value creation in the future. We are strongly committed to our Company’s long-term sustainable growth.
The information above reflects the period of time ending December 31, 2022, and the “peer group” reflected in the chart above represents the compensation peer group used for 2022 compensation developed by our independent compensation consultant Pearl Meyer. The peer group includes the following companies: 3D Systems Corporation, Badger Meter, Inc., Cerence Inc., Enerpac Tool Group Corp, ESCO Technologies, Inc., FARO Technologies, Inc., Helios Technologies Inc., Novanta Inc., Power Integrations, Inc., Raven Industries, Inc., RBC Bearings Incorporated, Semtech Corporation, SPS Commerce, Inc., Universal Display Corporation, and Vicor Corporation.
Although Proto Labs’ TSR performance shown in the chart above trailed that of the peer group, the compensation committee believes that pay and performance are appropriately aligned. Our 2021 and 2022 annual cash incentive payouts for our named executive officers were well below the target amounts. Additionally, long-term incentives awarded to our named executive officers are well below their initial grant date fair value; specifically, all outstanding stock options are underwater and no PSUs have been paid out in the last three years.
Key Actions and Decisions in 2022
In 2022, the Company made a number of important decisions as it relates to our named executive officer compensation program.

​ | Topic | ​ | ​ | Actions / Decisions | ​
​ | 2022 Salary Adjustments | ​ | ​ | ​✔ | ​ | ​ | Adjusted the base salary for Dr. Bodor by 20% to more closely align his base pay with comparable peers in the market and reflect his recent promotion to CEO. After the adjustment, Dr. Bodor’s base pay was at the 12th percentile when compared to peers in the market. | ​
​ |  | ​ | ​ | ✔ | ​ | ​ | Mr. Klaas and Mr. Kenison each received a base salary increase of 3% for their annual merit increase. | ​
​ |  | ​ | ​ | ✔ | ​ | ​ | Mr. Schumacher received a base salary increase of 21.5% in connection with his promotion to CFO in June 2022. | ​
​ | 2022 Annual Incentives and Long-Term Incentives | ​ | ​ | ✔ | ​ | ​ | ​Paid annual incentives to our named executive officers in the range of 24% - 41% of target for the partial achievement of corporate and regional objectives where applicable. The portion of Mr. Kenison’s annual incentive award tied to revenues for the Americas was not earned due to an unexpected negative economic impact on the achievement of regional objectives for the Americas region. Mr. Kenison was awarded a discretionary annual incentive award of 20% of target to partially offset the unexpected negative economic impact. | ​

Key Governance Attributes
Our compensation committee is committed to establishing an executive compensation program that reflects strong corporate governance attributes. The following table summarizes those corporate governance attributes.

​ | Things We Do | ​ | ​ | Things We Don’t Do | ​
​ | ​• | ​ | ​ | “Double-trigger” treatment for cash and accelerated equity vesting upon a change in control | ​ | ​ | ​• | ​ | ​ | No tax gross-ups on perquisites, severance or change in control payments | ​
​ | ​• | ​ | ​ | Meaningful stock ownership guidelines for our executive officers | ​ | ​ | ​• | ​ | ​ | No hedging/pledging of Proto Labs stock by executive officers | ​
​ | ​• | ​ | ​ | Requirement that executive officers hold 100% of after-tax shares from option exercises or RSU/PSU vesting until they have achieved their ownership requirement | ​ | ​ | ​• | ​ | ​ | No option repricing without shareholder approval | ​
​ | • | ​ | ​ | No excessive or additional perquisites unique to named executive officers | ​
​ | ​• | ​ | ​ | ​Continual review of our compensation programs for alignment with our shareholder expectations of driving profitable growth​ | ​
​ | ​• | ​ | ​ | Compensation recoupment (“clawback”) policy | ​ | ​ | ​ | ​
​ | ​• | ​ | ​ | Equity award approval policy | ​ | ​ | ​ | ​
​ | ​• | ​ | ​ | Independent compensation committee | ​ | ​ | ​ | ​
​ | ​• | ​ | ​ | Independent compensation consultant | ​ | ​ | ​ | ​
​ | ​• | ​ | ​ | Annual compensation risk assessment | ​ | ​ |  | ​

Say-on-Pay Results
The compensation committee values the opinions of our shareholders. At our 2022 annual meeting, the say-on- pay proposal received the approval of approximately 94% of the shares voted on the proposal. We considered this result to be an endorsement by our shareholders of our compensation program and maintained the majority of the fundamental features of our 2021 program for 2022. Further, since our Company began holding the say-on- pay vote, our shareholders have been overwhelmingly supportive of our compensation programs, with the say-on-pay proposal receiving greater than 90% support in each year.
Executive Transitions
Daniel Schumacher was appointed as Chief Financial Officer of the Company effective June 3, 2022. Prior to his appointment, Mr. Schumacher served as the Company’s Interim Chief Financial Officer, beginning December 1, 2021. The terms of his employment as Chief Financial Officer are summarized in the section titled “Employment Agreements.”
Arthur R. Baker III, Chief Technology Officer, involuntarily terminated employment with the Company effective April 15, 2022. Due to the nature of his separation from the Company, Mr. Baker was entitled to receive severance benefits. In accordance with his severance agreement, he executed a release of claims against the Company and is required to comply with a restrictive covenants agreement with respect to non-disclosure and non-competition. He received a severance package of 12 months of annualized base salary, paid in installments subject to limited

exceptions; a pro rata cash incentive payment amount for 2022, paid in a lump sum; an amount equal to the employer’s portion of health premiums for Mr. Baker and his dependents for the first 12 months of coverage under COBRA; and a pro rata immediate vesting for a portion of his unvested equity-based awards scheduled to vest in the year following his termination date.
Oleg Ryaboy was appointed as the Company’s Chief Technology Officer, effective September 9, 2022. The terms of his employment are summarized in the section titled “Employment Agreements.”
Executive Compensation Philosophy and Objectives
We believe our success depends in large measure on our ability to attract, retain and motivate a talented senior management team to effectively lead our Company in a dynamic and changing business environment, and that a competitive executive compensation program is essential to that effort. We believe that our executive compensation program should support our short- and long-term strategic and operational objectives, and reward corporate and individual performance that contributes to creating value for our shareholders.
Executives covered by this philosophy include the Chief Executive Officer (CEO), any “officer” of the Company as defined in Rule 16a-1(f) under the Securities Exchange Act of 1934, and any other management-level employee reporting directly to the CEO.
Consistent with this philosophy, our executive compensation program incorporates the following key principles and objectives:

• | Focus on total compensation for purpose of understanding the competitiveness of executive officer compensation;

• | Structure the compensation program so as to align the interests of our executive officers with those of our customers, employees, and shareholders;

• | Provide a competitive total compensation opportunity that includes target incentive goals that are reasonably achievable and aligned to long-term objectives;

• | Utilize equity-based awards in a manner designed to motivate long-term Company performance, increase shareholder value and emphasize their long-term retentive function;

• | Recognize and reward the achievement of Company and business unit goals as well as individual performance;

• | Provide compensation commensurate with the level of business performance achieved;

• | Provide greater compensation opportunities for individuals who have the most significant responsibilities and therefore the greatest ability to influence our achievement of strategic and operational objectives;

• | Structure the compensation program so that it is understandable and easily communicated to executives, shareholders and other constituencies;

• | Place increasing emphasis on incentive/variable compensation for positions of increasing responsibility; and

• | Make benefit programs available to executive officers generally consistent with those provided to salaried employees.

Compensation Decisions and Processes
The compensation committee of our board of directors, which consists solely of independent directors, generally has been responsible for overseeing our executive compensation program, including annually reviewing the ongoing compensation arrangements for each of our executive officers, including our CEO, and reporting those arrangements to our board.
Our compensation committee regularly receives and considers input from our CEO regarding the compensation and performance of the other executive officers, including recommendations as to compensation levels that the CEO believes are commensurate with an individual’s job performance, skills, experience, qualifications, criticality to our Company and development/career opportunities, as well as with our compensation philosophy, external market data and considerations of internal equity. With the assistance of our CFO, our CEO also has provided recommendations to the compensation committee regarding the establishment of performance goals for the annual cash incentive plan based on the operating budget approved by our board of directors. Our CEO regularly attends meetings of our compensation committee, except where the CEO’s own compensation is being considered or times when the committee meets in executive session. Our CEO makes no recommendations to the compensation committee regarding his or her own compensation. The compensation committee communicates
|27

TABLE OF CONTENTS

its views and decisions regarding compensation arrangements for our executive officers to our CEO, who generally has been responsible for implementing the arrangements.
In determining executive compensation, our compensation committee reviews and considers a number of factors, including individual and corporate performance, input from our CEO, peer group compensation and market data from third party compensation surveys (including Pearl Meyer, our independent compensation consultant), our compensation philosophy and key principles, the pay practices of a set of comparable companies, feedback received from shareholders concerning say-on-pay, and the committee’s collective experience and knowledge. We define our relevant peer group for executive talent, with assistance of Pearl Meyer, in the technology and industrial sectors, also taking into account size of the company, business models, and other factors. We have used market data primarily as a reference point to assess whether our compensation practices are reasonable, competitive and likely to achieve our objectives, and actually deliver compensation in amounts that are consistent with the compensation committee’s assessment of our Company’s relative performance. We target total compensation levels within a competitive range of the market median we calculated from the surveys and other compensation data we utilized. As a result, we do not establish specific compensation amounts or parameters for any executive officer position based on market data, recognizing that factors unique to each individual will ultimately determine that individual’s compensation, which may not necessarily be within the median range. In evaluating 2022 compensation, each of our executive officers was at or below the targeted range. Our compensation committee approves all awards to our executive officers under our 2022 Long-Term Incentive Plan.
Peer Group
In 2021, the compensation committee requested that its independent compensation consultant, Pearl Meyer, review our peer group used for executive compensation in 2022. Pearl Meyer used a multi-step process that went beyond basic financial characteristics to construct a peer group that we believe fits our market position and profile. The compensation committee and our board of directors reviewed information relating to this peer group when establishing base salaries, annual equity awards and target annual incentive compensation for 2022.
Pearl Meyer employed the following robust process to construct the proposed peer group.

• | First, Pearl Meyer identified a pool of potential companies that were U.S.-based, publicly-traded, and classified in the technology and industrial sectors.

• | Second, Pearl Meyer screened out companies that were outside of approximately one-third to three times that of our Company based on market capitalization, revenue, and number of employees.

• | Third, they reviewed additional financial operating parameters and identified companies with similar characteristics to our Company.

Overall, the new peer group used for 2022 compensation is similar to Proto Labs in terms of profitability and Proto Labs is approximately median in size of the peer group.
The compensation committee also reviewed the peer groups used for comparison by proxy advisory firms.
This process resulted in a select number of changes as shown below.

​ | 2021 Peer Group | ​ | ​ | Recommended Changes | ​ | ​ | 2022 Peer Group* | ​

TABLE OF CONTENTS

Below is information about companies in the peer group, as well as the corresponding information for Proto Labs, that Pearl Meyer referenced when constructing the peer group:

​ | ​ | ​ | ​ | Annual Revenue(1) | ​ | ​ | Market Capitalization(1) | ​
​ | 25th percentile | ​ | ​ | $443 million | ​ | ​ | $2.7 billion | ​
​ | 75th percentile | ​ | ​ | $672 million | ​ | ​ | $7.7 billion | ​
​ | Proto Labs | ​ | ​ | $435 million | ​ | ​ | $2.5 billion | ​

(1) | Revenue shown in this table is for the twelve-month period ended as of the most recently disclosed quarter prior to the 2021 meeting at which Pearl Meyer presented the peer group information to the compensation committee. Market capitalization reflects end of June 2021.

The compensation committee uses data about executive compensation at peer group companies as a tool to assess the reasonableness of the total compensation paid to our executive officers. As discussed above, we do not establish a percentile which any part of our executive’s compensation or any executive’s overall compensation must meet or exceed.
In 2022, the compensation committee requested that Pearl Meyer again review our peer group to be used for 2023 executive compensation. Pearl Meyer used the same multi-step process to recommend changes to the peer group used for 2023 compensation.
Elements of Executive Compensation
Our executive compensation program historically has been comprised of three primary elements—base salary, an annual cash incentive, and equity-based long-term incentives. The primary elements of our compensation program for 2022 were consistent with our 2021 compensation program. While all elements of our executive compensation program are intended to collectively achieve our overriding purpose of attracting, retaining and motivating talented executives, the table below identifies the additional specific purposes of each element as reflected in our 2022 compensation program.

​ | Compensation Component | ​ | ​ | Form of Compensation | ​ | ​ | Purpose | ​
​ | Base Salary | ​ | ​ | Cash | ​ | ​ | • | ​ | ​ | Compensate each executive officer relative to their individual responsibilities, experience and performance | ​
​ | ​ | ​ | ​ |  | ​ | ​ | • | ​ | ​ | Provide steady cash flow not contingent on short-term variations in Company performance | ​
​ | Annual Incentive​ | ​ | ​ | Cash​ | ​ | ​ | • | ​ | ​ | Align compensation with our annual corporate financial performance | ​
​ | ​ | ​ | ​ |  | ​ | ​ | • | ​ | ​ | Reward achievement of short-term financial objectives | ​
​ |  | ​ | ​ |  | ​ | ​ | • | ​ | ​ | Provide participants with a meaningful total cash compensation opportunity (base salary plus annual incentive) | ​
​ | Long-Term Incentives | ​ | ​ | Stock Options, Restricted Stock Units and Performance Stock Units | ​ | ​ | ​• | ​ | ​ | Align compensation with our long-term returns to shareholders | ​
​ | ​ | ​ | ​ | • | ​ | ​ | Encourage long-term retention | ​
​ |  | ​ | ​ | • | ​ | ​ | Create a long-term performance focus | ​
​ |  | ​ | ​ | • | ​ | ​ | Provide executive ownership opportunities | ​

We seek to minimize perquisites for executive officers which are unique to our executive officers. Our compensation committee has not adopted a formal or informal policy for allocating compensation among the various elements, or between fixed and at-risk, cash and non-cash elements or between long- and short-term compensation; however, the committee considers total compensation and then adjusts the mix among each element of compensation based on market comparisons, individual role and performance. As noted earlier, however, we do place greater emphasis on incentive-based and variable forms of compensation for executives with more significant responsibilities, reflecting their greater capacity to affect our performance and results.
Base Salaries
At the time an executive officer is first hired, his or her base salary generally is established through individual negotiations between us and the executive officer, taking into account judgments as to the executive officer’s qualifications, experience, responsibilities, prior salary history, internal pay equity considerations and market factors.
The compensation committee annually reviews the base salaries of our executive officers near the end of each year and bases any adjustments for the following year on merit and market considerations. Merit-based
|29

TABLE OF CONTENTS

adjustments primarily reflect an assessment of an individual’s performance. Any market-based adjustments reflect an assessment of the competitive positioning of an individual’s salary with comparable positions in the market based on market data provided to the compensation committee by the compensation consultant and other market surveys the compensation committee might use.
The annual base salary of each of our named executive officers is set forth in the table below, as well as the increases from 2021:

​ | Name | ​ | ​ | 2022 Annual Base Salary | ​ | ​ | 2021 Annual Base Salary | ​ | ​ | Percentage Change from 2021 Annual Base Salary to 2022 Annual Base Salary | ​
​ | Robert Bodor(1) | ​ | ​ | $600,000 | ​ | ​ | $500,000 | ​ | ​ | 20% | ​
​ | Daniel Schumacher(2) | ​ | ​ | $360,000 | ​ | ​ | $206,799 | ​ | ​ | ​22% | ​
​ | Michael R. Kenison | ​ | ​ | $350,200 | ​ | ​ | $340,000 | ​ | ​ | 3% | ​
​ | Bjoern Klaas | ​ | ​ | $346,734 | ​ | ​ | $336,635 | ​ | ​ | 3% | ​
​ | Oleg Ryaboy(3) | ​ | ​ | $350,000 | ​ | ​ | $— | ​ | ​ | * | ​
​ | Arthur R. Baker III(4) | ​ | ​ | $96,107 | ​ | ​ | $318,558 | ​ | ​ | * | ​

(1) | Dr. Bodor’s salary was adjusted by 20% to more closely align his base pay with comparable peers in the market and reflect his recent promotion to CEO. After the adjustment, Dr. Bodor’s base pay was at the 12th percentile when compared to peers in the market.

(2) | Effective June 3, 2022, Mr. Schumacher began serving as CFO. Prior to being named CFO, Mr. Schumacher served as Interim CFO and, prior to that, Vice President of Investor Relations and Financial Planning and Analysis (“FP&A”). Mr. Schumacher’s annual base salary as Interim CFO was $296,152.

(3) | Effective September 9, 2022, Mr. Ryaboy joined the Company as Chief Technology Officer.

(4) | Effective April 15, 2022, Mr. Baker terminated employment with the Company. Mr. Baker’s annual base salary represents total salary paid during 2022.

Annual Incentive Program
All of our named executive officers participate in our annual incentive program. The annual incentive program payouts for 2022 were a function of two metrics:

• | 75% of the annual bonus target was based on annual revenue growth, calculated without regard to foreign currency exchange rates. We refer to this aspect of the annual incentive program as the revenue factor.

• | 25% of the annual bonus target was based on budgeted adjusted operating margin. We refer to this aspect of the annual incentive program as the adjusted operating income (“AOI”) factor. For purposes of calculating attainment of the AOI portion of the annual incentives, AOI is defined as operating income before incentive compensation expense, stock-based compensation expense, amortization expense, acquisition expenses and other one-time expenses not indicative of core operations, calculated as a percentage of revenue.

Revenue growth and AOI were selected as the primary financial objectives for determining the 2022 annual incentive payouts because our primary objective continues to be to grow our Company profitably.
The compensation committee approved 2022 revenue and AOI objectives for our Company as a whole and for each of our major geographic business units (the United States, Europe, Middle East and Africa (“EMEA”) and Japan). The compensation committee approved a modification in the performance metrics for annual bonuses in connection with our Company’s exit from the Japanese market on May 31, 2022. Global performance continued to include the Japanese revenue attainment factor through May 31, 2022, and following that date, global performance excludes the Japanese attainment factor from both planned performance and actual performance. All other factors used to determine annual bonuses remained the same. The inclusion of business unit performance objectives enables us to tailor annual incentive opportunities so as to reward each executive officer for the performance of those portion(s) of our Company for which the officer had the most direct responsibility. The following are the percentage allocations for revenue and AOI across each named executive officer’s target bonus opportunity.

​ | ​Name | ​ | ​ | ​Revenue (75%) | ​ | ​ | AOI (25%) | ​
​ | Consolidated | ​ | ​ | ​Geographic Unit | ​ | ​ | Consolidated | ​
​ | ​Robert Bodor | ​ | ​ | 100% | ​ | ​ | ​ | ​ | ​ | 100% | ​
​ | Daniel Schumacher | ​ | ​ | 100% | ​ | ​ |  | ​ | ​ | 100% | ​
​ | ​Michael R. Kenison | ​ | ​ | 35% | ​ | ​ | 65% | ​ | ​ | 100% | ​
​ | ​Bjoern Klaas | ​ | ​ | 35% | ​ | ​ | 65% | ​ | ​ | 100% | ​
​ | Oleg Ryaboy | ​ | ​ | 100% | ​ | ​ |  | ​ | ​ | 100% | ​
​ | Arthur R. Baker III | ​ | ​ | 100% | ​ | ​ | ​ | ​ | ​ | 100% | ​

TABLE OF CONTENTS

A target payout expressed as a percentage of annual base salary is established for each named executive officer annually. For 2022, their target payout percentages were as follows:

​ | Name | ​ | ​ | Target Payout as % of 2022 Salary | ​
​ | Robert Bodor | ​ | ​ | 100% | ​
​ | Daniel Schumacher | ​ | ​ | 65% | ​
​ | Michael R. Kenison | ​ | ​ | 60% | ​
​ | Bjoern Klaas | ​ | ​ | 50% | ​
​ | Oleg Ryaboy | ​ | ​ | 50% | ​
​ | Arthur R. Baker III | ​ | ​ | 50% | ​

The revenue factor of our plan pays out 100% at targeted revenue achievement on a consolidated basis or for each region, as applicable, for each named executive officer. The payout would be zero for 2022 revenue below the threshold of 88% attainment of the annual targets for our Company as a whole and each of its business units. The payment is 30% of the annual bonus at the threshold amounts of 88% attainment, and increases in amounts specified by the compensation committee to the degree revenue exceeds the respective threshold amounts up to a maximum of 200%.
The AOI factor pays out 100% at targeted AOI achievement on a consolidated basis for each named executive officer. The payout would be zero for 2022 if AOI is below 40% of the target amount (the threshold amount). AOI payouts increase above threshold in amounts specified by the compensation committee, to the degree that AOI exceeds the threshold amount, up to a maximum of 200%. For AOI performance between threshold and target, the payout factor would increase proportionately between 40% and 100%, or about 0.2 percentage points for each basis point in additional AOI, and between target and maximum, the payout factor would increase proportionately between 100% and 200%, or about 0.2 percentage points for each basis point in additional AOI. For 2022, the AOI performance was below threshold and therefore no payout was made for that factor.
The compensation committee may, in its discretion, adjust annual incentive payout amounts on an individual basis. The compensation committee exercised that discretion with regard to Mr. Kenison’s 2022 annual incentive award, granting a 20% discretionary annual incentive award to partially offset the unexpected negative economic impact in the Americas region.
The following table summarizes the 2022 thresholds and targets for the revenue factor and the AOI factor approved by the compensation committee and the actual performance during 2022 in terms of both revenue and AOI, as well as the related payout factors:

​ | Objective | ​ | ​ | 2022 Threshold Growth (%) | ​ | ​ | 2022 Threshold Amount ($) | ​ | ​ | 2022 Target Growth (%) | ​ | ​ | 2022 Target Amount ($) | ​ | ​ | Actual Performance ($)(1) | ​ | ​ | Actual Performance (%)(1) | ​ | ​ | Final Payout Factor | ​

(1) | Our actual revenue performance is equal to our 2022 revenue adjusted for the effects of 2022 budgeted foreign currency exchange rates. Actual AOI performance is equal to adjusted operating margin achieved in 2022. Our actual revenue performance is equal to our 2022 revenue ($488.4 million), adjusted for the effects of 2022 budgeted foreign currency exchange rates ($5.7 million).

(2) | For consolidated revenue performance between threshold and target, the payout factor would increase proportionately between 30% and 100%, or about 1.1 percentage points for each $1 million in additional consolidated revenue.

(3) | For United States revenue performance between threshold and target, the payout factor would increase proportionately between 30% and 100%, or about 1.5 percentage points for each $1 million in additional United States revenue.

(4) | For EMEA revenue performance between threshold and target, the payout factor would increase proportionately between 30% and 100%, or about 8.5 percentage points for each $1 million in additional EMEA revenue.

The annual incentive amount paid to, as well as such amount’s percentage of target achieved for, each named executive officer in 2022 were as follows:

​ | Name | ​ | ​ | 2022 Actual Incentive Amount ($) | ​ | ​ | Percent of Annual Incentive Target Achieved (%) | ​
​ | Robert Bodor | ​ | ​ | $243,600 | ​ | ​ | 41% | ​

​ | Arthur R. Baker III(4) | ​ | ​ | ​$— | ​ | ​ | 0% | ​

(1) | Effective June 3, 2022, Mr. Schumacher began serving as CFO. Prior to being named CFO, Mr. Schumacher served as Interim CFO and, prior to that, Vice President of Investor Relations and FP&A. Mr. Schumacher’s 2022 incentive amount represents the pro-rata portion of his 2022 incentive amount as of the date of his promotion to CFO and includes a $50,000 incentive amount for time in his role as Interim CFO.

(2) | Mr. Kenison’s amount represents a combination of consolidated and geographic results. Mr. Kenison’s incentive bonus included a $20,487 discretionary amount in consideration of the unexpected negative economic impact in the Americas region. Despite economic challenges, the Americas region achieved strong year-over-year growth in our 3D printing and CNC service lines and was 0.2% away from achieving the United States revenue threshold amount. In an effort to reward individual performance in line with our past practice, the compensation committee determined that a 20% discretionary bonus would be awarded.

(3) | Mr. Ryaboy’s 2022 incentive amount represents a pro-rata portion of his 2022 incentive amount from the date he joined the Company.

(4) | Effective April 15, 2022, Mr. Baker terminated employment with the Company. Therefore, Mr. Baker was not eligible for an annual incentive payment.

Long-Term Incentive Program
Our compensation committee considers the employee’s total compensation and then adjusts the mix among base salary, annual incentive and long-term incentive based on market comparisons, individual role and performance. Our compensation committee generally has determined the size of individual grants using its collective business judgment and experience, taking into account factors such as the role and responsibility of the individual executive, an evaluation of the expected and actual performance of each executive, internal pay equity considerations and market factors. We generally have not utilized a formulaic approach to determine the size of individual equity awards to our executives. In 2022, the compensation committee has continued to structure the long-term incentive program for our named executive officers to include a mix of stock options, RSUs and PSUs.
In addition to annual equity awards, in certain cases we have granted equity awards in connection with an individual’s initial employment with us, upon promotions or other changes in responsibilities, or in recognition of significant achievements. These additional equity awards are made outside our typical annual grant cycle, and are subject to our equity award approval policy summarized below in “Other Compensation and Equity-Related Policies—Equity Award Approval Policy.”
In accordance with our pay-for-performance philosophy, under which the Company’s under performance is reflected in the named executive officers’ compensation, the compensation committee determined that none of the PSUs granted in 2018, 2019, or 2020 were earned or vested because our Company’s performance was below the financial threshold goals. In addition, all outstanding stock options held by the named executive officers were underwater as of December 31, 2022.

2022 Long-Term Equity-Based Compensation
As noted above, in 2022 the compensation committee awarded stock options, RSUs and PSUs to our named executive officers. Such grants, which were made in 2022 pursuant to the 2022 Long-Term Incentive Plan (the “LTIP”), were as follows:

​ | Name | ​ | ​ | Aggregate Grant Date Fair Value of 2022 Equity Awards | ​ | ​ | Number of RSUs Awarded | ​ | ​ | Number of Stock Options Awarded | ​ | ​ | Target Number of PSUs Awarded | ​
​ | Robert Bodor | ​ | ​ | $3,764,745 | ​ | ​ | 11,785 | ​ | ​ | 25,147 | ​ | ​ | 23,570 | ​
​ | Daniel Schumacher | ​ | ​ | $672,929 | ​ | ​ | 8,387 | ​ | ​ | 8,605 | ​ | ​ | 3,077 | ​
​ | Michael R. Kenison | ​ | ​ | $527,543 | ​ | ​ | 3,788 | ​ | ​ | 4,042 | ​ | ​ | 1,894 | ​
​ | Bjoern Klaas | ​ | ​ | $527,543 | ​ | ​ | 3,788 | ​ | ​ | 4,042 | ​ | ​ | 1,894 | ​
​ | Oleg Ryaboy | ​ | ​ | $500,017 | ​ | ​ | 9,361 | ​ | ​ | 6,307 | ​ | ​ | — | ​

The aggregate grant date fair value of equity awarded to Dr. Bodor in 2022 closely aligns his equity-based compensation with comparable peers in the market and reflects his recent promotion to CEO. Further, 87% of Dr. Bodor’s compensation is considered to be “at risk”.
The stock options awarded to our named executive officers have an exercise price equal to 100% of the fair market value of a share of our common stock on the date of grant. Each stock option granted will vest and becomes exercisable as to 25% of the shares in four annual installments beginning on February 13, 2023 and has a 10-year term. For stock options granted prior to an individual becoming a named executive officer, the vesting date and schedule may differ. Unvested options will immediately become vested and exercisable in full upon the named executive officer’s death or disability and if, within one year of a change in control, the named executive officer’s employment is terminated without cause or for good reason.
The RSUs awarded to our named executive officers will vest as to 25% of the shares in four annual installments beginning on February 13, 2023. For RSUs granted prior to an individual becoming a named executive officer, the vesting date and schedule may differ. Unvested RSUs will immediately vest in full upon the named executive officer’s death or disability and if, within one year of a change in control, the named executive officer’s employment is terminated without cause or for good reason. No dividend equivalents are paid on the RSUs.
The PSUs awarded to our named executive officers are expressed in terms of a target number of PSUs (as noted in the table above), with between 0% and 200% of that target number of shares capable of being earned and vesting at the end of the January 1, 2022 to December 31, 2024 performance period depending on our Company’s three-year cumulative TSR performance relative to the Russell 2000 Growth Index. The pay and performance scale for the 2022 PSU grants is as follows:

​ | Relative TSR Percentile | ​ | ​ | PSU Payout (% of Target) | ​
​ | Below 25th percentile | ​ | ​ | 0% | ​
​ | 25th percentile | ​ | ​ | 50% | ​
​ | 50th percentile | ​ | ​ | 100% | ​
​ | 75th percentile or greater | ​ | ​ | 200% | ​

If our TSR is less than 0% over the performance period, the PSU payout is capped at 100% of target. In making the decision in 2020 to move to relative TSR from our historical practice of measuring organic revenue and adjusted EPS growth, the compensation committee reflected on the difficulty of setting multi-year financial goals, and the potential for misalignment of pay and performance. Further, the compensation committee believes that relative TSR represents a good alignment tool for purpose of compensating management on shareholder return performance. The compensation committee plans to continually evaluate the PSU program in the future to determine the best metrics and structure to motivate and reward management.
The number of PSUs determined to have been earned at the end of the performance period will vest at that time, and each vested PSU will be paid out in one share of our common stock. A PSU award will be forfeited if the award recipient’s employment ends before the scheduled vesting date except in situations involving retirement, disability, a qualifying termination under a severance agreement, death or a change in control. If employment ends due to retirement, disability or a qualifying termination under a severance agreement before the scheduled vesting date, a pro rata portion of the number of PSUs that would have been earned at the end of the performance period if employment had continued will vest on the scheduled vesting date. The pro rata portion will be based on the portion of the performance period that elapsed prior to the date of termination. If employment ends due to an award recipient’s death, a pro rata portion (determined in the same manner) of the target number of PSUs will vest

at that time. If a change in control of our Company occurs before the scheduled vesting dates of the award, the performance period will be truncated and a pro rata portion of the number of PSUs determined to have been earned during the truncated performance period will vest as of the date of the change in control. The pro rata portion will be based on the portion of original performance period that elapsed prior to the date of the change in control.
PSUs Granted in 2020
The PSUs awarded to our named executive officers in 2020 were expressed in terms of a target number of PSUs, with between 0% and 150% of that target number of shares capable of being earned and vesting at the end of the January 1, 2020 to December 31, 2022 performance period depending on our Company’s three-year cumulative TSR performance relative to the Russell 2000 Growth Index. The pay and performance scale for the 2020 PSU grants was as follows:

​ | Relative TSR Percentile | ​ | ​ | PSU Payout (% of Target) | ​
​ | Below 25th percentile | ​ | ​ | 0% | ​
​ | 25th percentile | ​ | ​ | 50% | ​
​ | 50th percentile | ​ | ​ | 100% | ​
​ | 75th percentile or greater | ​ | ​ | 150% | ​

The Company’s three-year relative TSR was at the 13th percentile, 0% of target. As such, none of the PSUs granted in 2020 were earned by the named executive officers.
Other Executive Benefits
Our named executive officers generally receive health and welfare benefits under the same programs and subject to the same terms as our other salaried employees. These benefits include medical, dental and vision benefits, short- and long-term disability insurance, accidental death and dismemberment insurance and basic life insurance. Our named executive officers are also eligible to participate in our 401(k) retirement plan, under which our Company provides a matching contribution in an amount equal to 100% of the first 3% of compensation contributed by a participant and 50% of the next 2% of compensation contributed. We also provide supplemental benefits to our executive officers who are based outside of the United States as part of compensation packages that are intended to be competitive in the respective local markets.
Employment Agreements
Employment Agreement with Dr. Bodor
Dr. Bodor’s employment agreement, dated January 29, 2021 (the “CEO Agreement”), provides that his employment with the Company is at-will and his employment may be unilaterally terminated by Dr. Bodor or the Company at any time for any reason, subject to the terms of the CEO Agreement. Pursuant to the CEO Agreement, Dr. Bodor receives an initial annual base salary of $500,000 and is eligible for an annual target cash incentive bonus payment equal to 100% of his annual base salary. Dr. Bodor will be eligible for an annual equity grant on terms and conditions that are comparable to those applicable to grants made to other senior executives of the Company.
Dr. Bodor’s severance benefits are summarized under “Potential Payments Upon Termination or Change in Control.”
Offer Letter Agreements with Daniel Schumacher
On December 1, 2021, the Company entered into a letter employment agreement (the “Interim CFO Agreement”) with Daniel Schumacher to serve as an Interim Chief Financial Officer.
Mr. Schumacher served as Interim Chief Financial Officer for approximately 6 months, during which his Interim CEO Agreement provided for an annualized base salary of $296,153 and a pro-rated annual target cash incentive bonus payment of $110,000 for fiscal year 2022. Mr. Schumacher also received an additional equity grant pursuant to the Company’s Long-Term Incentive Plan, of RSUs valued at $150,000, to be vested in full after one year. The Interim CFO agreement did not provide for severance.
On June 3, 2022, the Company entered into a new offer letter agreement (the “CFO Agreement”) with Mr. Schumacher. Under the CFO Agreement, Mr. Schumacher has served as Chief Financial Officer since June 3, 2022.
Pursuant to the CFO Agreement, Mr. Schumacher receives an annualized base salary of $360,000 and was eligible for an annual target cash incentive bonus payment of $234,000 for fiscal year 2022. Mr. Schumacher also received an additional equity grant pursuant to the Company’s Long-Term Incentive Plan comprised of RSUs valued at $300,000, $150,000 in Options and $150,000 in PSUs. The CFO Agreement does not provide for severance but the Company has entered into a severance agreement with Mr. Schumacher, summarized under “Potential Payments Upon Termination or Change in Control”.

Offer Letter with Oleg Ryaboy
On September 2, 2022, the Company entered into a letter employment agreement (the “CTO Agreement”) with Oleg Ryaboy to serve as Chief Technology Officer. The CTO Agreement provides that his employment is at-will and his employment may be unilaterally terminated by Mr. Ryaboy or the Company at any time for any reason. Pursuant to the CTO Agreement, Mr. Ryaboy receives an annualized base salary of $350,000 and was eligible for an annual target cash incentive bonus payment of $75,000 for fiscal year 2022. In 2023 and beyond, Mr. Ryaboy will be eligible for an annual target cash incentive bonus payment equal to 50% of his annual base salary. Mr. Ryaboy also received an equity grant pursuant to the Company’s Long-Term Incentive Plan comprised of RSUs valued at $375,000 and $125,000 in stock options. Mr. Ryaboy will be eligible for an annual equity grant under the Company’s Long Term Incentive Plan. The CTO Agreement does not provide for severance.
Severance and Change in Control Benefits
We have entered into severance arrangements on our form of severance agreement with our named executive officers, with the exception of Dr. Bodor, whose employment agreement provides for severance benefits, and Mr. Ryaboy. For a summary of the material terms and conditions of our agreements with the named executive officers providing for payments in connection with termination of employment and changes in control of our Company, see “Potential Payments upon Termination or Change in Control.”
The equity award agreements under the LTIP provide for “double trigger” acceleration of exercisability or vesting of equity awards in connection with a change in control, meaning that both a change in control and either a failure to continue, assume or replace outstanding awards or a termination of employment are necessary before acceleration will occur. The compensation committee believes that the double trigger structure avoids an unintended windfall to executives who retain their employment and their equity awards in the event of a friendly change in control, but still provides them appropriate incentives to cooperate in negotiating any change in control in which they believe they could lose their jobs.
Other Compensation and Equity-Related Policies
Clawback Policy
In 2014, we adopted an Executive Officer Incentive Compensation Recovery Policy for recovery of incentive compensation from our executive officers under certain circumstances, and in May 2019 we adopted an expanded version of such policy (as expanded, the “Clawback Policy”), which was updated in May 2022. The Clawback Policy provides that we will, in all appropriate circumstances as determined by the compensation committee, and to the extent permitted by applicable law, require reimbursement or forfeiture of all or a portion of any incentive compensation awarded to our executive officers after the adoption of the policy where the compensation committee has determined that either:

(1) | All of the following factors are present:

• | We are required to prepare an accounting restatement due to material noncompliance with any financial reporting requirement under the securities laws;

• | The award, vesting or payment of the incentive compensation was predicated upon the achievement of certain financial results that were the subject of the restatement and such award, vesting or payment occurred or was received during the three-year period preceding the date on which we were required to prepare the restatement; and

• | A smaller award, vesting or payment would have occurred or been made to the executive officer based upon the restated financial results.

(2) | There has been misconduct resulting in either a violation of law or of our Company policy that has caused significant financial or reputational harm to our Company and either the executive officer committed the misconduct or failed in his or her responsibility to manage or monitor the applicable conduct or risks.

In the circumstances described in (1) above, we will, to the extent deemed appropriate by the compensation committee, seek to recover or cancel the amount(s) by which an executive officer’s incentive compensation that was awarded, vested or paid during the three-year period referenced above exceeded the amount(s) that would have been awarded, vested or paid based on the restated financial results, net of taxes paid or payable by the executive officer with respect to the recoverable compensation. In the circumstances described in (2) above, we will, to the extent deemed appropriate by our compensation committee, seek to recover or cancel an executive officer’s incentive compensation that was awarded, vested or paid during any fiscal year in which the misconduct occurred.

TABLE OF CONTENTS

The Company expects to revise its Clawback Policy in the next year to comply with new NYSE and SEC rules once they are finalized.
Executive Stock Ownership Guidelines
In 2014, we adopted stock ownership guidelines applicable to our executive officers, which we updated in 2018 and 2021. The guidelines are applicable to each of our executive officers and provide that each executive officer is expected to own shares of our common stock with a value at least equal to the amount shown below:

• | CEO – Five times annual base salary

• | All other executive officers – One times annual base salary

Each executive officer has five years from the date he or she becomes subject to the guidelines to achieve compliance with the guidelines. Until an executive officer has achieved compliance with the ownership guidelines, the individual must retain 100% of the “net profit shares” resulting from any option exercise or from the exercise, vesting or settlement of any other form of equity-based compensation award. For these purposes, “net profit shares” refers to that portion of the number of shares subject to the exercise, vesting or settlement of an award that the covered individual would receive had he or she authorized the Company to withhold shares otherwise deliverable in order to satisfy any applicable exercise price or withholding taxes. As of December 31, 2022, all of our named executive officers, except for Bjoern Klaas, were either in compliance with the guidelines or within the five-year period to achieve compliance with the guidelines. The compensation committee granted Mr. Klaas a one-year extension to meet the requirements of the stock ownership guidelines.
Equity Award Approval Policy
Our equity award approval policy permits us to make equity-based awards at any time other than during “blackout periods” provided for in our insider trading policy, which generally run from the eleventh of the month in which each fiscal quarter closes through the end of the second trading day following the public release of our financial results for that quarter. The policy does, however, permit us to approve an award during a blackout period, provided the effective date of the grant and the concurrent pricing of the grant occur on the first trading day after the blackout period ends.
Other Equity-Related Policies
We prohibit our executive officers from engaging in certain types of transactions in our stock, including short sales, pledges of our stock and other hedging transactions with respect to our stock. This policy is intended to prevent our executive officers from reducing the effect that decreases in the value of our stock have on their financial position. The LTIP requires that all stock options granted under the plan have an exercise price that is not less than the fair market value of a share of our common stock on the date the grant is made. The LTIP also prohibits re-pricing or exchanging underwater stock options without shareholder approval.
Tax Considerations
Section 280G of the Internal Revenue Code of 1986, as amended (the “Code”), disallows a tax deduction with respect to excess parachute payments to certain executives of companies which undergo a change in control. In addition, Code Section 4999 imposes a 20% excise tax on the individual with respect to the excess parachute payment. Parachute payments are compensation linked to or triggered by a change in control and may include, but are not limited to, bonus payments, severance payments, certain fringe benefits, and payments and acceleration of vesting from long-term incentive plans including stock options and other equity-based compensation. Excess parachute payments are parachute payments that exceed a threshold determined under Code Section 280G based on the executive’s prior compensation. As discussed above, we do not provide tax gross-ups on income attributable to severance or other payments that are deemed made in connection with a change in control.
Code Section 409A requires that “nonqualified deferred compensation” be deferred and paid under plans or arrangements that satisfy the requirements of the statute with respect to the timing of deferral elections, timing of payments and certain other matters. Failure to satisfy these requirements can expose employees and directors to accelerated income tax liabilities, substantial additional taxes and interest on their vested compensation under such plans. Accordingly, as a general matter, it is our intention to design and administer our compensation and benefit plans and arrangements for all of our employees and directors, including our named executive officers, so that they are either exempt from, or satisfy the requirements of, Code Section 409A.
Code Section 162(m) disallows a tax deduction to public companies for compensation of more than $1 million paid in any taxable year to each “covered employee,” consisting of the CEO and the three other highest paid executive officers employed at the end of the year (other than the CFO), plus any person who served as CEO or CFO at any time the year, as well as any person who was ever identified as a covered employee in 2017 or any subsequent year.

TABLE OF CONTENTS

COMPENSATION COMMITTEE REPORT
The compensation committee assists the board of directors in establishing a philosophy and policies regarding executive and director compensation; provides oversight of the administration of our director and executive compensation programs and administers our equity-based plans; reviews the compensation of directors, named executive officers and senior management and prepares any report on executive compensation required by the rules and regulations of the SEC or other regulatory body, including this compensation committee report.
In performing its oversight responsibilities, the compensation committee has reviewed and discussed the Compensation Discussion and Analysis with management. Based on the review and discussions, the compensation committee has recommended to the board that the Compensation Discussion and Analysis be included in this Proxy Statement for the 2023 Annual Meeting of Shareholders.
COMPENSATION COMMITTEE
Rainer Gawlick, Chair
Moonhie Chin
Donald G. Krantz
COMPENSATION RISK ASSESSMENT
Management and the compensation committee, with the assistance of the compensation consultant, assess the risk of the employee compensation policies and practices, including those that apply to our executive officers. Management has reviewed our compensation plans, program design and existing practices as well as global and local compensation policies, programs and practices applicable to all employees. Management then analyzed the likelihood and magnitude of potential risks, focusing on whether any of our compensation policies and practices varied significantly from our overall risk and reward structure, whether any such policies and practices incentivized individuals to take risks that were inconsistent with our goals, and whether any such policies and practices have resulted in establishing an inappropriate balance between short-term and long-term incentive arrangements.
Management has discussed the findings of the risk assessment with the compensation committee. Based on the assessment, we have concluded that our compensation policies and practices are aligned with the interests of shareholders, appropriately reward pay for performance and do not create risks that are reasonably likely to have a material adverse effect on our Company.
CONFLICT OF INTEREST ANALYSIS
Our compensation committee has considered the relationships that its compensation consultant has had with our Company, the members of the compensation committee and our executive officers, as well as the policies that such compensation consultant has in place to maintain its independence and objectivity, and has determined that the work performed by the compensation consultant has raised no conflicts of interest.

Grants of Plan-Based Awards
The annual incentive plan is described in the Compensation Discussion and Analysis (“CD&A”). The long-term incentive program, including a description of types of equity awards, vesting schedules, performance conditions, and events that would accelerate vesting, for grants made in 2022 is summarized in the CD&A. No dividends or dividend equivalents are paid on RSUs or PSUs.

(1) | In accordance with the terms of our equity grant timing policy, the RSUs, PSUs and stock option grants to our named executive officers identified in the table were granted effective as of the end of the second trading day following the public release of our financial results for the fourth quarter of 2021, even though the compensation committee approved the grants on an earlier date.

(2) | As discussed above in “Compensation Discussion and Analysis—Elements of Executive Compensation,” amounts in this column represent an award of PSUs under the LTIP capable of being earned and vesting at the end of a three-year performance period depending on our Company’s three-year cumulative TSR performance relative to the Russell 2000 Growth Index and the award recipient’s continued employment. The PSU vesting terms in the event of certain terminations of employment or a change in control of our Company are described above in “Elements of Executive Compensation—Long-Term Equity-Based Compensation.” No dividend equivalents are paid on the PSUs.

(3) | Amounts in this column represent awards of RSUs under the LTIP which vest as to 25% of the shares in four annual installments beginning on February 13, 2023. Unvested RSUs will immediately vest in full upon the named executive officer’s death or disability and if, within one year of a change in control, the named executive officer’s employment is terminated without cause or for good reason. No dividend equivalents are paid on the RSUs.

(4) | Amounts in this column represent awards of stock options under the LTIP which vest as to 25% of the shares in four annual installments beginning on February 13, 2023. Unvested options will immediately become vested and exercisable in full upon the named executive officer’s death or disability and if, within one year of a change in control, the named executive officer’s employment is terminated without cause or for good reason.

(5) | The actual value to be realized by a named executive officer depends upon the appreciation in value of our stock and the length of time the award is held. No value will be realized with respect to any stock option award if our stock price does not increase following the grant date. For a description of the assumptions used in computing grant date fair value for stock option awards pursuant to ASC 718, see Note 13 to our Consolidated Financial Statements for the year ended December 31, 2022 contained in our Annual Report on Form 10-K. The grant date fair value of each RSU award and PSU award (at target) was computed in accordance with ASC 718.

Potential Payments upon Termination or Change in Control
Below is a description of the agreements, plans and arrangements that were in effect as of December 31, 2022 providing for payments or benefits to our named executive officers upon termination of employment or in connection with a change in control of our Company.
Robert Bodor Employment Agreement, effective March 1, 2021
Pursuant to our employment agreement with Dr. Bodor, if we voluntarily terminate his employment without “cause” (and other than as a result of his death or disability) or if he resigns for “good reason,” as defined in the employment agreement (a “qualifying termination”), provided that Dr. Bodor complies with certain conditions (including execution of a general waiver and release of claims and complying with a non-disclosure and inventions assignment agreement and a non-competition agreement), then he will be entitled to the benefits summarized below.
If Dr. Bodor’s employment with us terminates during the term of his employment agreement and prior to any change in control (as defined in the employment agreement) or after any 18-month period following a change in control, which we refer to as the “transition period,” and if the termination is a “qualifying termination,” then subject to certain conditions:

• | we will pay Dr. Bodor an amount equal to one times his annualized base salary in substantially equal installments in accordance with our regular payroll practices over the 12-month period immediately following the termination date, subject to limited exceptions;

• | we will pay Dr. Bodor an amount equal to one times his target annual cash incentive bonus for the calendar year in which his employment with us terminates, payable in a lump sum;

• | we will pay our share of premiums due Dr. Bodor and his eligible dependents under COBRA for the first 12 months of COBRA coverage, if timely elected by Dr. Bodor; and

• | if Dr. Bodor has any unvested equity-based awards as of the termination date, a pro rata portion of any unvested awards scheduled to vest on the next anniversary of the grant date will vest immediately.

If Dr. Bodor’s termination date occurs during the term of the employment agreement and within 90 days prior to a change in control, and if the termination is a qualifying termination and Dr. Bodor reasonably demonstrates within 30 days after the change in control that the qualifying termination arose in connection with or in anticipation of the change in control, then, we will:

• | pay Dr. Bodor an amount equal to two times his annualized base salary, payable in a lump sum;

• | pay Dr. Bodor an amount equal to two times his target annual cash incentive bonus for the calendar year in which his employment with us terminates, payable in a lump sum;

TABLE OF CONTENTS

• | pay our share of premiums due for Dr. Bodor and his eligible dependents for 18 months of coverage under COBRA, if timely elected by Dr. Bodor; and

• | pay Dr. Bodor an amount equal to the value of any unvested equity-based awards held by him as of the termination date that were forfeited as of the termination date.

If a change in control occurs during the term of his employment agreement and Dr. Bodor’s termination date occurs upon a change in control during the transition period, and if the termination is a qualifying termination, then, subject certain conditions:

• | we will pay Dr. Bodor an amount equal to two times his annualized base salary in substantially equal installments in accordance with our Company’s regular payroll practices over the 24-month period immediately following the termination date, subject to limited exceptions;

• | we will pay Dr. Bodor an amount equal to two times his target annual cash incentive bonus for the calendar year in which his employment with us terminates, payable in a lump sum;

• | we will pay our share of premiums due for Dr. Bodor and his eligible dependents under COBRA for the first 18 months of COBRA coverage, if timely elected by Dr. Bodor; and

• | if Dr. Bodor has any unvested equity-based awards as of the termination date, all such unvested awards will vest immediately on Dr. Bodor’s termination date.

If Dr. Bodor’s employment with us is terminated due to his death or disability, then, in addition to payment of accrued but unpaid salary and benefits, Dr. Bodor (or his estate) will be entitled to receive a pro rata portion of his target annual cash incentive award for the then-current year based on the portion of the year he was employed by us prior to termination.
In the event that the severance pay and other benefits provided for in the CEO Agreement or otherwise payable to Dr. Bodor constitute Section 280G “parachute payments” and would be subject to excise taxes, then such benefits will be either be delivered in full or delivered as to such lesser extent which would result in no portion of such severance pay and other benefits being subject to excise taxes, whichever results in the receipt by Dr. Bodor of the greatest amount of benefits.
Severance Agreements with Other Named Executive Officers
As of December 31, 2022, we had entered into severance agreements with each of our other named executive officers except for Dr. Bodor and Mr. Ryaboy. If we voluntarily terminate the employment of any such officer without “cause” (and other than as a result of his death or disability) or if he resigns for “good reason,” as defined in the applicable severance agreement, provided that such officer complies with certain conditions (including execution of a general waiver and release of claims and execution of a restrictive covenants agreement with respect to non-disclosure and non-competition) described in the applicable severance agreement, then he will be entitled to the benefits summarized below.
If such officer’s employment with us terminates at a time other than during the period from the date of a change in control to the 18-month anniversary of the Change in Control (the “transition period”), and if the termination is a qualifying termination, then, subject to certain conditions:

• | we will pay such officer an amount equal to his annualized base salary (the “severance”) in substantially equal installments in accordance with our regular payroll practices over the 12-month period immediately following the termination date, subject to limited exceptions;

• | we will pay such officer a pro rata cash incentive payment amount, payable in a lump sum;

• | we will pay our share of premiums due for such officer and his eligible dependents for the first 12 months of coverage under COBRA (the “COBRA benefit”); and

• | if such officer has any unvested equity-based awards as of the termination date, a pro rata portion of any unvested awards scheduled to vest on the next anniversary of the grant date will vest immediately.

If such officer’s termination date occurs during the transition period, and if the termination is a qualifying termination, then, subject to certain conditions we will pay the severance and COBRA benefits described above, plus:

• | we will pay such officer an amount equal to the sum of (i) his target annual cash incentive payment for the calendar year in which his employment with us terminates plus (ii) a pro rata cash incentive payment amount, payable in a lump sum; and

• | if such officer has any unvested equity-based awards as of the termination date, all such unvested awards will vest immediately on his termination date.

|43

TABLE OF CONTENTS

If such officer’s termination date occurs within 90 days prior to a change in control, and if the termination is a qualifying termination and he reasonably demonstrates within 30 days after the change in control that the qualifying termination arose in connection with or in anticipation of the change in control, then, in addition to the compensation he otherwise is entitled to receive in connection with a qualifying termination (not during a transition period), we will:

• | pay such officer an amount equal to his target annual cash incentive payment for the calendar year in which his or her employment with us terminates, payable in a lump sum; and

• | pay such officer an amount equal to the value of any unvested equity-based awards held by him as of the termination date that were forfeited as of the termination date.

In the event that the severance pay and other benefits provided for in the severance agreements constitute Section 280G “parachute payments” and would be subject to excise taxes, then such benefits will be either be delivered in full or delivered as to such lesser extent which would result in no portion of such severance pay and other benefits being subject to excise taxes, whichever results in the receipt by executive of the greatest amount of benefits.
LTIP
Under the LTIP, upon termination for cause, all unvested awards and all unexercised stock options and SARs will be forfeited. Upon termination due to death or disability, any unvested portion of an award will immediately become vested and exercisable in full and options and SARs will remain exercisable for twelve months after the date of termination. Upon termination for any other reason, the then currently vested and exercisable portion of any option or SAR will remain exercisable for three months after termination (unless the participant dies during that three-month period, in which case the post-termination exercise period will be extended to twelve months).
Any post-termination exercise period may, however, be extended by the compensation committee if the issuance of shares upon such exercise would then violate applicable registration requirements under the Securities Act. Any such post-termination exercise period may not, however, extend beyond the expiration date of any option or SAR. After giving effect to any accelerated vesting as provided above, all unvested and unexercisable portions of outstanding awards will be forfeited in connection with a termination of service.
Under the LTIP, unless otherwise provided in an award agreement, if a change in control, as defined in the LTIP, occurs that involves a sale of all or substantially all of our assets or a merger, consolidation, reorganization or statutory share exchange involving our Company, our board of directors or compensation committee are to take one or more of the following actions with respect to outstanding awards under the LTIP:

• | Arrange for the surviving or successor entity to continue, assume or replace some or all of the outstanding awards under the LTIP.

• | Accelerate the vesting and exercisability of outstanding awards prior to and conditioned upon the occurrence of the event and provide that unexercised options and SARs will be terminated at the effective time of the event.

• | Cancel any outstanding award in exchange for payment to the holder of the amount of the consideration that would have been received in the event for the number of shares subject to the award, less the aggregate exercise price (if any) of the award.

• | Provide that if an award is continued, assumed or replaced in connection with such an event and if within 18 months after the event a participant experiences an involuntary termination of service other than for cause, the participant’s outstanding awards will vest in full, will immediately become fully exercisable and will remain exercisable for one year following termination.

• | Make certain adjustments to awards as provided in the LTIP.

In the event of a change in control that does not involve a merger, consolidation, reorganization, statutory share exchange or sale of all or substantially all of our Company’s assets, our board of directors or compensation committee, in its discretion, may provide (1) that any outstanding award will become fully vested and exercisable upon the change in control or upon the termination of the participant’s service without cause within 18 months after the change in control, (2) that any outstanding option or SAR will remain exercisable during all or some specified portion of its remaining term, or (3) that any outstanding award will be canceled in exchange for payment to the participant of the amount of the consideration that would have been received in the change in control for the number of shares subject to the award less the aggregate exercise price (if any) of the award.
The form of option award agreement approved by the compensation committee for use under the LTIP provides that if, within 12 months of a change in control, an optionee’s employment is involuntarily terminated without cause or the optionee resigns for good reason, and if the option or a replacement thereof then remains outstanding, it will immediately become exercisable in full and remain exercisable for one year following termination.

TABLE OF CONTENTS

The form of RSU award agreement approved by the compensation committee for use under the LTIP provides that if, within 12 months of a change in control, a participant’s employment is involuntarily terminated without cause or the participant resigns for good reason, and if the award then remains outstanding, any unvested portion of the RSUs or a replacement thereof will immediately become vested.
The form of PSU award agreement approved by the compensation committee for use under the LTIP provides that if a change in control of our Company occurs before the scheduled vesting dates of the award, the performance period will be truncated and a pro rata portion of the number of PSUs determined to have been earned during the truncated performance period will vest as of the date of the change in control. The pro rata portion will be based on the portion of original performance period that elapsed prior to the date of the change in control.
The LTIP provides that in the event any payments or benefits provided under the LTIP taken together with other payments an individual may receive in connection with a change in control may constitute a “parachute payment” under Section 280G of the Code, such payments or benefits may be reduced to provide the individual with the best after-tax result. Specifically, the individual will receive either a reduced amount so that the excise tax imposed under Section 4999 of the Code is not triggered, or the individual will receive the full amount of the payments and benefits and then be liable for any excise tax.
Potential Payments
The following table sets forth quantitative information with respect to potential payments to be made to each of the named executive officers or their beneficiaries upon termination in various circumstances, assuming termination on December 31, 2022. In the following table, unless indicated otherwise, all equity is listed at its dollar value as of December 31, 2022 and all stock options are valued based on the difference between $25.53, the closing price for one share of our common stock on the NYSE on December 30, 2022 (the last trading day of 2022), and the applicable exercise price.

(1) | The LTIP provides that, in connection with a change in control, we may, among other actions, (i) arrange for the surviving or successor entity to continue, assume or replace outstanding awards under the LTIP, (ii) accelerate the vesting and exercisability of outstanding awards upon the occurrence of the change in control or (iii) cancel outstanding awards in exchange for payment of the amount of consideration that would have been received in the change in control for the number of shares subject to the award, less the aggregate exercise price (if any) of the award. The amounts shown assume acceleration of all outstanding awards under the LTIP in connection with a change in control.

(2) | Pursuant to agreements between us and each of our named executive officers each such named executive officer is entitled to the payments and benefits summarized above if his or her employment terminates within 90 days prior to a change in control, and if the termination is without cause or for good reason and the executive reasonably demonstrates within 30 days after the change in control that the qualifying termination arose in connection with or in anticipation of the change in control.

(3) | Upon termination of the executive officer’s employment by us without cause or by the executive for good reason or due to retirement or disability, a pro rata portion (based on the portion of the performance period that elapsed prior to the date of termination) of the number of PSUs that would have been earned at the end of the applicable performance periods if employment had continued will vest on the scheduled vesting date. Because the PSU awards are not accelerated under such circumstances, and because the determination regarding the number of outstanding PSUs to be earned cannot be made until after the applicable performance periods end on December 31, 2023, 2024, and 2025, no accelerated values for outstanding PSU awards are included in the table columns relating to retirement, disability and without cause and good reason terminations.

Upon a change in control of our Company, the performance period for the PSUs is truncated and a pro rata portion (based on the portion of original performance period that elapsed prior to the date of the change in control) of the number of PSUs determined to have been earned during the truncated performance period vests as of the date of the change in control. The amounts included in the table reflect the PSUs earned assuming the applicable performance periods had ended on December 31, 2022, prorated based on the portion of the original performance periods that had elapsed prior to December 31, 2022.
Upon the executive officer’s death, a pro rata portion of the target number of PSUs vest.

(4) | Mr. Baker’s employment was terminated during 2022. The amounts in this table represent the payments and benefits due to him under his severance agreement in connection with his termination.

CEO Pay Ratio
We determined that the 2022 annual total compensation of the median employee, determined as of December 31, 2020, other than our CEO, Robert Bodor, was $54,744; Dr. Bodor’s 2022 annual total compensation was $4,619,545; and the ratio of these amounts was 84-to-1.
For our 2022 CEO pay ratio analysis, we determined that we could use the same median employee that we identified in 2020, as permitted by SEC rules. There have been no changes in either our employee population or our employee compensation arrangements that we believe would significantly impact our 2022 pay ratio disclosure. Similarly, there has been no material change in our median employee’s circumstances that we reasonably believe would result in a significant change to our 2022 pay ratio disclosure. As of December 31, 2020, our total population consisted of 2,408 employees. To identify the median compensated employee, we used a Consistently Applied Compensation Measure (CACM) defined as the aggregation of base salary or regular wages and overtime pay. Further, we annualized salary and wages for individuals not employed for a full year.
This pay ratio is a reasonable estimate calculated in a manner consistent with SEC rules based on our payroll and employment records and the methodology described above. The SEC rules for identifying the median compensated employee and calculating the pay ratio based on that employee’s annual total compensation allow companies to adopt a variety of methodologies, to apply certain exclusions, and to make reasonable estimates and assumptions that reflect their compensation practices. As such, the pay ratio reported by other companies may not be comparable to the pay ratio reported above, as other companies may have different employment and compensation practices and may utilize different methodologies, exclusions, estimates and assumptions in calculating their own pay ratios.

(5) | Our Company-selected measure, which is the measure we believe represents the most important financial performance not otherwise presented in the table above that we used to link CAP for our NEOs for fiscal 2022 to our Company’s performance is our Company’s revenue in constant currency, a non-GAAP measure, which is GAAP revenue calculated to exclude the impact of foreign currency exchange rates.

Required Tabular Disclosure of Most Important Measures to Determine 2022 CAP
The items listed below represent the most important financial metrics we used to determine CAP for fiscal year 2022 as further described in our CD&A within the sections titled “Annual Incentive Program,” “Long-Term Incentive Program” and “2022 Long-Term Equity-Based Compensation.”

​ | Most Important Performance Measures | ​
​ | Revenue in Constant Currency(1) | ​
​ | 3-Year Cumulative TSR Performance relative to Russell 2000 Growth Index | ​
​ | Adjusted Operating Income(2) | ​

(1) | Revenue in constant currency is a non-GAAP financial measure that consists of GAAP revenue which is then adjusted to eliminate the impact of changes in foreign currency exchange rates.

(2) | Adjusted operating income is a non-GAAP financial measure that consists of GAAP income from operations which is then adjusted to eliminate the effect of items or events that the Committee determines in its discretion should be excluded for compensation purposes.

Relationship between Pay and Performance
The following charts present a graphical comparison of CAP to our current and former PEOs and the average CAP to our Non-PEO NEOs set forth in the Pay Versus Performance Table above, as compared against the following performance measures: our (1) TSR, (2) peer group TSR, (3) net income (loss), and (4) revenue in constant currency. The charts also provide a comparison of our TSR to the peer group TSR for the three-year period.

DIRECTOR COMPENSATION
Our director compensation program is designed to compensate our non-employee directors fairly for work required for a company of our size and scope and to align our non-employee directors’ interests with the long-term interests of our shareholders. Directors who are also our employees receive no additional compensation for serving on our board of directors. The compensation committee periodically reviews the compensation arrangements for our non-employee directors and makes recommendations to our board of directors. In September 2021, the compensation committee, with the advice of its compensation consultant, conducted a review of our director compensation program. This review analyzed the structure and the overall level and mix of compensation delivered by our director compensation program as compared to our peer group.
The non-employee director compensation program provides the directors with the option to elect whether to receive their annual equity award in the form of restricted stock units or deferred stock units (“DSUs”). This feature is designed to provide flexibility to our directors and to also make our director compensation program consistent with those of the companies in our peer group.
A summary of our non-employee director compensation program follows:

Annual cash retainer: | ​ | ​ | $50,000
| ​ | ​ |
Additional annual cash retainer for Chairman: | ​ | ​ | $80,000
| ​ | ​ |
Annual cash retainer for committee chairs: | ​ | ​ | Audit Committee: $20,000 Compensation Committee: $15,000 Nominating and Governance Committee: $10,000
| ​ | ​ |
Annual cash retainer for other committee members: | ​ | ​ | Audit Committee: $8,000 Compensation Committee: $6,000 Nominating and Governance Committee: $4,000
| ​ | ​ |
Annual equity award: | ​ | ​ | $145,000 grant date fair value of restricted stock units or deferred stock units (at the director’s election) which become vested in full on the earlier of the first anniversary of the grant date or the date of the next annual meeting of our shareholders
| ​ | ​ |
New director equity award: | ​ | ​ | Restricted stock units or deferred stock units (at the director’s election) with $145,000 grant date fair value, granted and vested on the date the director is first elected to the board
| ​ | ​ |
| ​ | ​ | In addition, a grant of pro-rata portion of the restricted stock units or deferred stock units (at the director’s election) which was granted to directors at the most recent annual meeting of shareholders, which will vest at the following annual meeting of shareholders
| ​ | ​ |
Meeting fees: | ​ | ​ | Generally none, but compensation committee has the discretion to provide for meeting fees if the number of board of directors meetings exceeds eight per year or if the number of meetings of any committee exceeds six per year

We have stock ownership guidelines for our non-employee directors. Each such director is expected to own shares of our common stock with a fair market value of at least five times the amount of the annual board member retainer, and to achieve this ownership level within three years after first joining our board of directors. Until a director has satisfied this ownership guideline, the director may not dispose of any shares of our common stock, except for sales which proceeds will be used to pay the exercise price in connection with an option exercise or to pay applicable income taxes in connection with the vesting, exercise or payout of any equity-based award. For purposes of this guideline, shares subject to an unvested or unexercised equity-based award will be counted as owned shares. All of our directors who are not significant shareholders have met these guidelines with the exception of Ms. Moonhie Chin. The compensation committee approved granting a one-year extension to Ms. Chin to meet the requirements of the stock ownership guidelines.

PROPOSAL 2—RATIFICATION OF SELECTION OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
The audit committee has selected Ernst & Young LLP (“EY”) as our independent registered public accounting firm for fiscal 2023, and the board of directors is asking shareholders to ratify that selection. Although current law, rules and regulations, as well as the audit committee charter, require our independent registered public accounting firm to be engaged, retained, and supervised by the audit committee, the board of directors considers the selection of an independent registered public accounting firm to be an important matter of shareholder concern and considers a proposal for shareholders to ratify such selection to be an opportunity for shareholders to provide direct feedback to the board of directors on a significant issue of corporate governance.
If the selection of EY as our independent registered public accounting firm for fiscal 2023 is not ratified by our shareholders, the audit committee will review its future selection of an independent registered public accounting firm in the light of that vote result.
Representatives of EY will be present at the Annual Meeting, will have an opportunity to make a statement if they so desire, and will be available to respond to appropriate questions.

​ | THE BOARD, UPON RECOMMENDATION OF THE AUDIT COMMITTEE, UNANIMOUSLY RECOMMENDS THAT SHAREHOLDERS VOTE “FOR” THE RATIFICATION OF ERNST & YOUNG LLP AS OUR INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR FISCAL 2023. | ​

AUDIT COMMITTEE REPORT
The following is the report of the audit committee. The audit committee has reviewed and discussed our audited financial statements for the fiscal year ended December 31, 2022 with our management. In addition, the audit committee has discussed with Ernst & Young LLP, our independent auditors (“EY”), the matters required to be discussed by the applicable requirements of the Public Company Accounting Oversight Board (“PCAOB”) and the SEC. The audit committee also has received the written disclosures and the letter from EY as required by the applicable requirements of the PCAOB regarding the independent accountant’s communications with the audit committee concerning independence, and the audit committee has discussed with EY the independence of EY.
Based on the audit committee’s review of the matters noted above and its discussions with our independent auditors and our management, the audit committee recommended to the board of directors that the audited financial statements be included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2022.
Each year, the audit committee evaluates the qualifications, performance, tenure and independence of our independent auditor and determines whether to re-engage the current independent auditor. In doing so, the audit committee considers the quality and efficiency of the services provided by the auditors, the auditors’ global capabilities and the auditors’ technical expertise and knowledge of our operations and industry. Based on this evaluation, the audit committee has appointed EY as independent auditor for the fiscal year ending December 31, 2023. The members of the audit committee and the Board believe that, due to EY’s knowledge of our Company and of the industry in which we operate, it is in the best interests of our Company and our shareholders to continue retention of EY to serve as our independent auditor. Although the audit committee has the sole authority to appoint the independent auditor, the Board is submitting the selection of EY to our shareholders for ratification as a matter of good corporate practice.

“Audit Fees” consisted of fees for the audit of our annual financial statements, including audited financial statements presented in our Annual Report on Form 10-K, audit of our internal control over financial reporting, review of the financial statements presented in our quarterly reports on Form 10-Q, and services that are normally provided by the independent registered public accountants in connection with statutory and regulatory filings or engagements for those fiscal years. This category also includes advice on audit and accounting matters that arose during, or as a result of, the audit or the review of interim financial statements and statutory audits required by non-U.S. jurisdiction.
“Audit-Related Fees” consisted of assurance and related services by EY that are reasonably related to the performance of the audit or review of our financial statements and are not reported above under “Audit Fees.”
“Tax Fees” consisted of fees for tax consultation and tax compliance services.
Pre-approval Policy. The audit committee has established a policy governing our use of the services of our independent registered public accountants. Under the policy, the audit committee is required to pre-approve all audit and non-audit services performed by our independent registered public accountants in order to ensure that the provision of such services does not impair the public accountants’ independence. In fiscal years 2022 and 2021, all fees identified above under the captions “Audit Fees,” “Audit-Related Fees” and “Tax Fees” that were billed by EY were approved by the audit committee in accordance with SEC requirements.
The audit committee has determined that the rendering of the services other than audit services by EY is compatible with maintaining their independence.

PROPOSAL 3—ADVISORY VOTE ON EXECUTIVE COMPENSATION
We are asking our shareholders to provide advisory approval of the compensation of our named executive officers included in this Proxy Statement, as we have described it above in “Compensation Discussion and Analysis.” While this vote is advisory and nonbinding, the compensation committee will consider the outcome of the vote when making future compensation decisions for our executive officers. We believe our compensation program aligns the interests of our executive officers and shareholders and serves the best interests of our shareholders.
The board of directors recommends that shareholders approve the following advisory resolution:
RESOLVED, that the compensation paid to the individuals identified in the Summary Compensation Table, as disclosed in this Proxy Statement pursuant to the compensation disclosure rules of the SEC (which disclosure includes the Compensation Discussion and Analysis section and the related compensation tables and accompanying footnotes and narratives), is hereby approved.

PROPOSAL 4—APPROVAL OF AN AMENDMENT TO THE PROTO LABS, INC. 2022 LONG-TERM INCENTIVE PLAN
Introduction
Our 2022 Long-Term Incentive Plan (the “2022 Plan”) was initially approved by the board of directors on July 8, 2022, subject to shareholder approval. Our shareholders approved the 2022 Plan at our special meeting of shareholders (the “Special Meeting”) on August 29, 2022. The initial share reserve under the 2022 Plan was 1,236,000 shares, plus any shares subject to outstanding awards under the 2012 Long-Term Incentive Plan (the “Prior Plan”) that expire, are cancelled or are forfeited.
As of March 22, 2023, there were 606,167 shares of our common stock remaining available for awards under the 2022 Plan. The compensation committee (referred to as the “Committee” in this Proposal 4) anticipates that such number of shares will not be sufficient to grant annual equity awards in 2024 in amounts determined to be appropriate by the Committee. As a result, the Committee recommended, and on March 28, 2023, the board of directors approved, an amendment to the 2022 Plan to increase the number of shares for issuance under the 2022 Plan by an additional 559,500 shares, subject to shareholder approval.
If our shareholders do not approve this proposal, the amendment to the 2022 Plan will not take effect and the 2022 Plan will continue in effect under its original terms.
Shareholder Approval and Board of Directors Recommendation
Shareholder approval of the amendment to the 2022 Plan is being sought in order to (i) satisfy the shareholder approval requirements of the New York Stock Exchange and (ii) obtain shareholder approval of the number of shares that may be subject to incentive stock options under Internal Revenue Code (“Code”) Section 422. The proposed amendment to the 2022 Plan does not extend the ten-year term of the 2022 Plan.
The maximum number of shares that may be issued under the 2022 Plan, if this amendment is approved by shareholders, will be 1,795,500, of which 1,165,667 shares would be available for future awards, plus any shares subject to awards under the Prior Plan that are forfeited.
The board of directors recommends that our shareholders vote FOR approval of the amendment to the 2022 Plan because it will provide us with a share reserve that will enable us to continue to provide a competitive mix of compensation to our key employees.
Basis for the Requested Share Reserve Increase
Long-term equity-based incentives play a critical role in our executive compensation program, motivating executives to make decisions that focus on long-term shareholder value creation, aligning executives’ interests with the interests of shareholders, providing additional incentives, and serving to attract and retain the best available people for positions of responsibility with the Company. Our ability to continue to promote our long-term business success and provide competitive levels of equity-based compensation is considered to be of utmost importance to our business. The board of directors believes that it is in the best interests of our shareholders to increase the number of shares available under the 2022 Plan to ensure sufficient shares for continued equity-based compensation.
As discussed in the proxy statement for the Special Meeting, when we sought shareholder approval of the 2022 Plan, we believed that the shares reserved for issuance under it (along with shares from the Prior Plan becoming available for future grant due to forfeitures and cancellations) would be sufficient to enable us to grant equity awards under the 2022 Plan for approximately three to four years. This estimate was based on a forecast that took into account various factors, such as future growth in the population of eligible participants, the rate of future compensation increases, the rate at which shares are returned to the 2022 Plan reserve through forfeitures, cancellations and the like, the level at which performance-based awards pay out, and our future stock price performance.
Since the time of that forecast, our stock price has differed substantially from what was estimated at that time. As a result, we believe the number of shares initially reserved for issuance under the 2022 Plan is sufficient for approximately two years of annual equity awards, which include grants already made in 2022 and 2023, and grants expected to be made later in in 2023 as well as grants in early 2024. While the shares remaining available under the current share reserve is expected to be sufficient for planned equity grants through early 2024, due to the need to grant increased numbers of shares subject to full-value awards based on the current stock price, we do not expect to have enough shares to make grants through the date of the 2024 Annual Meeting without amending the 2022 Plan to add more shares.

Each year, the Committee reviews our overall compensation strategy and determines allocations of cash and equity compensation in light of our pay-for-performance philosophy. We believe that equity compensation is critical in motivating key employees and that it effectively aligns employee compensation with shareholder interests. We are also committed to effectively managing our share reserves for equity compensation while minimizing shareholder dilution. If the amendment to the 2022 Plan is not approved and we are unable to grant equity compensation in the future, we may need to consider other compensation alternatives, such as increasing cash compensation, and we would be at a severe disadvantage if we could not use equity awards covering a meaningful number of shares to recruit and retain key talent in this competitive market.
We recognize that equity compensation awards dilute shareholder equity and must be used judiciously. Our equity compensation practices are designed to be in line with industry norms, and we believe our historical share usage has been responsible and mindful of shareholder interests. Certain provisions in the 2022 Plan are designed to protect our shareholders’ interests and to reflect corporate governance best practices, as described in further detail below.
Generally, we expect to continue making equity awards consistent with our practices over the past three years, and to maintain an average annual burn rate over the next three years in line with our average for the 2020-2022 period. On that basis, we expect that shares of common stock available for future awards if the amendment to the 2022 Plan is approved would be sufficient for equity awards grants for approximately one to two years.
In setting the number of additional shares to be available for issuance under the proposed amendment, we considered our estimated competitive usage needs going forward for existing employees and potential new hires for approximately the next one to two years, with such timing dependent on a variety of factors, including the price of our shares and hiring activity during the next few years, forfeitures of outstanding awards, and noting that future circumstances may require us to change our current equity grant practices. We cannot predict our future equity grant practices, the future price of our shares or future hiring activity with any degree of certainty at this time, and the share reserve under the amendment to the 2022 Plan could last for a shorter or longer time.
Expectations regarding future share usage under the 2022 Plan are naturally based on a number of assumptions regarding factors such as future growth in the population of eligible participants, the rate of future compensation increases, the rate at which shares are returned to the 2022 Plan reserve through forfeitures, cancellations and the like, the level at which performance-based awards pay out, and our future stock price performance. While the Committee believes that the assumptions utilized are reasonable, future share usage will differ from current expectations to the extent that actual events differ from the assumptions utilized.
Key Compensation Practices
The 2022 Plan includes a number of features that we believe are consistent with the interests of our shareholders and sound corporate governance practices, including the following:

• | No repricing of underwater options or stock appreciation rights without shareholder approval. The 2022 Plan prohibits, without shareholder approval, actions to reprice, replace, or repurchase options or stock appreciation rights (“SARs”) when the exercise price per share of an option or SAR exceeds the fair market value of the underlying shares.

• | No evergreen. The 2022 Plan does not have an evergreen or similar provision, which provides for an automatic replenishment of shares available for grant.

|57

TABLE OF CONTENTS

• | No liberal share recycling. We may not add back to the 2022 Plan’s share reserve shares that are delivered or withheld to pay the exercise price of an option award or to satisfy a tax withholding obligation in connection with any awards, shares that we repurchase using option exercise proceeds or shares subject to a SAR award that are not issued in connection with the stock settlement of that award upon its exercise.

• | No liberal definition of “change in control.” No change in control would be triggered by shareholder approval of a business combination transaction, the announcement or commencement of a tender offer or any board assessment that a change in control may be imminent.

• | No automatic accelerated vesting of equity awards upon a change in control.

• | No payment of dividends or dividend equivalents on unearned awards. The 2022 Plan prohibits the payment of dividends or dividend equivalents in connection with an award until it vests.

• | Annual limit on compensation to non-employee directors. The 2022 Plan contains an annual limit on the aggregate value of all awards granted during a calendar year to any non-employee director.

• | No excise tax gross-up benefits. The 2022 Plan does not provide for any gross-up payments to offset any excise tax expenses.

• | Clawback. The 2022 Plan requires the recapture or claw back of all or a portion of awards in connection with financial restatements and other events for officers.

Description of the 2022 Plan
The major features of the 2022 Plan are summarized below. The summary is qualified in its entirety by reference to the full text of the 2022 Plan as proposed to be amended, which is attached to this Proxy Statement as Appendix A.
Eligible Participants. Employees, consultants, advisors and non-employee directors of the Company are eligible to receive awards under the 2022 Plan. As of March 22, 2023, there were 2,507 employees, seven non-employee directors of the Company and an indeterminate number of consultants and advisors who are eligible to receive awards under the 2022 Plan.
Administration. The 2022 Plan is administered by the Committee. To the extent consistent with applicable law, the Committee may delegate its duties, power and authority under the 2022 Plan to any one or more of its members, or, with respect to awards to participants who are not themselves our directors or executive officers, to one or more of our other directors or executive officers or to a committee of the board comprised of one or more directors. The Committee may also delegate non-discretionary administrative duties to other persons, agents or advisors.
The Committee has the authority to determine the persons to whom awards will be granted, the timing, type and number of shares covered by each award, and the terms and conditions of the awards. The Committee may also establish and modify rules to administer the 2022 Plan, interpret the 2022 Plan and any related award agreement, cancel or suspend an award, accelerate the vesting of an award and otherwise modify or amend the terms of outstanding awards to the extent permitted under the 2022 Plan, and require or permit the deferral of the settlement of an award. Unless an amendment to the terms of an award does not materially impair the rights of the participant or is necessary to comply with applicable laws or stock exchange rules, a participant who would be adversely affected by such an amendment must consent to it.
Except in connection with equity restructurings and other situations in which share adjustments are specifically authorized, the 2022 Plan prohibits the Committee from repricing any outstanding “underwater” option or SAR awards without the prior approval of our shareholders. For these purposes, a “repricing” includes amending the terms of an underwater option or SAR award to lower the exercise price, canceling an underwater option or SAR award in conjunction with granting a replacement option or SAR award with a lower exercise price, canceling an underwater option or SAR award in exchange for cash, other property or grant of a new full value award, or otherwise making an underwater option or SAR award subject to any action that would be treated under accounting rules as a “repricing.”
Available Shares and Limitations on Awards. Currently, a maximum of 1,236,000 shares of our common stock may be the subject of awards and issued under the 2022 Plan. The proposed amendment would increase the number of shares available for issuance under the 2022 Plan by an additional 559,500 shares
The shares of common stock issuable under the 2022 Plan are authorized and unissued shares of our Company. The share limitations under the 2022 Plan are subject to adjustment for changes in our corporate structure or shares, as described below.
58|

TABLE OF CONTENTS

Any shares of common stock subject to an award under the 2022 Plan, or to an award under the Prior Plan that was outstanding on the date our shareholders approved the 2022 Plan, that expires, is cancelled or forfeited, or is settled or paid in cash will, to the extent of such expiration, cancellation, forfeiture or cash settlement, automatically replenish the 2022 Plan share reserve and become available for future awards. Any shares tendered or withheld to pay the exercise price or satisfy a tax withholding obligation in connection with any award, any shares repurchased by the Company using option exercise proceeds and any shares subject to a SAR award that are not issued in connection with the stock settlement of the SAR award on its exercise may not be used again for new grants.
Awards that may be settled solely in cash will not reduce the share reserve and will not reduce the shares authorized for grant to a participant in any calendar year. Awards granted or shares of our common stock issued under the 2022 Plan upon the assumption of, or in substitution or exchange for, outstanding equity awards previously granted by an entity acquired by us or any of our subsidiaries (referred to as “substitute awards”) will not reduce the share reserve under the 2022 Plan.
The 2022 Plan provides that the aggregate grant date fair value of all awards granted during any calendar year to any non-employee director, together with the amount of any cash fees or retainers paid to such non-employee director during such calendar year with respect to such individual’s service as a non-employee director, shall not exceed $750,000.
Share Adjustment Provisions. If certain transactions with our shareholders occur that cause the per share value of our common stock to change, such as stock splits, spin-offs, stock dividends or certain recapitalizations (referred to as “equity restructurings”), the Committee will equitably adjust (i) the class of shares issuable and the maximum number and kind of shares subject to the 2022 Plan, and (ii) outstanding awards as to the class, number of shares and price per share. Other types of transactions may also affect our common stock, such as reorganizations, mergers or consolidations. If there is such a transaction and the Committee determines that adjustments of the type previously described in connection with equity restructurings would be appropriate to prevent any dilution or enlargement of benefits under the 2022 Plan, the Committee will make such adjustments as it may deem equitable.
Clawback and Recoupment. With regard to Section 16 officers and any other management-level employee reporting directly to our chief executive officer, the Committee may cancel any award or require the participant to reimburse any previously paid compensation provided under the 2022 Plan or an award agreement in the event of certain accounting restatements, as well as additional events specified by the Committee, or as required by securities laws.
Types of Awards. The 2022 Plan permits us to award stock options, SARs, restricted stock awards, stock unit awards, performance awards, other stock-based awards and cash-based awards to eligible recipients. These types of awards are described in more detail below.
Options. Employees of our Company or any subsidiary may be granted options to purchase common stock that qualify as “incentive stock options” within the meaning of Section 422 of the Code, and any eligible recipient may be granted options to purchase common stock that do not qualify as incentive stock options, referred to as “nonqualified stock options.” The per share exercise price to be paid by a participant at the time an option is exercised may not be less than 100% of the fair market value of one share of our common stock on the date of grant (or 110% for incentive stock options granted to certain shareholders), unless the option is granted as a substitute award as described earlier. “Fair market value” under the 2022 Plan as of any date means the closing sale price of a share of our common stock on the New York Stock Exchange on that date.
The total purchase price of the shares to be purchased upon exercise of an option will be paid by the participant in cash unless the Committee allows exercise payments to be made, in whole or in part, (i) by means of a broker-assisted sale and remittance program, (ii) by delivery to us (or attestation as to ownership) of shares of common stock already owned by the participant, or (iii) by a “net exercise” of the option in which a portion of the shares otherwise issuable upon exercise of the option are withheld by us, or such other method permitted by the Committee. Any shares delivered or withheld in payment of an exercise price will be valued at their fair market value on the exercise date.
An option will vest and become exercisable at such time, in such installments and subject to such conditions as may be determined by the Committee, and no option may have a term greater than 10 years from its date of grant (or five years for incentive stock options granted to certain shareholders). No dividends or dividend equivalents may be paid or credited with respect to shares subject to an option award.
|59

TABLE OF CONTENTS

The aggregate fair market value of shares of our common stock with respect to which incentive stock options granted to any participant may first become exercisable during any calendar year may not exceed $100,000. Any incentive stock options that become exercisable in excess of this amount will be treated as nonqualified stock options. The maximum number of shares that may be issued upon the exercise of incentive stock option awards under the 2022 Plan is equal to the size of the 2022 Plan’s share reserve as described above, and as proposed to be increased.
Stock Appreciation Rights. A SAR award provides the right to receive a payment from us equal to the difference between (i) the fair market value as of the date of exercise of the number of shares of our common stock as to which the SAR is being exercised, and (ii) the aggregate exercise price of that number of shares. The Committee determines whether payment will be made in shares of our common stock, cash or a combination of both. The exercise price per share of a SAR award will be determined by the Committee, but may not be less than 100% of the fair market value of one share of our common stock on the date of grant, unless the SAR is granted as a substitute award as described earlier. No dividends or dividend equivalents may be paid or credited with respect to shares subject to a SAR award. A SAR award may not have a term greater than 10 years from its date of grant, and will be subject to such other terms and conditions, consistent with the terms of the 2022 Plan, as may be determined by the Committee.
Restricted Stock Awards. A restricted stock award is an award of our common stock that vests at such times and in such installments as may be determined by the Committee. Until it vests, the shares subject to the award are subject to restrictions on transferability and the possibility of forfeiture. The Committee may impose such restrictions or conditions to the vesting of restricted stock awards as it deems appropriate, including that the participant remain continuously in our service for a certain period or that we, or any of our subsidiaries or business units, satisfy specified performance goals. Any dividends or distributions payable with respect to shares that are subject to the unvested portion of a restricted stock award will be subject to the same restrictions and risk of forfeiture as the shares to which such dividends or distributions relate. Participants are entitled to vote restricted shares prior to the time they vest.
Stock Unit Awards. A stock unit award is a right to receive the fair market value of a specified number of shares of our common stock, payable in cash, shares, or a combination of both, that vests at such times, in such installments and subject to such conditions as may be determined by the Committee. Until it vests, a stock unit award is subject to restrictions and the possibility of forfeiture. Stock unit awards will be subject to such terms and conditions, consistent with the other provisions of the 2022 Plan, as may be determined by the Committee. The Committee may provide for the payment of dividend equivalents on stock unit awards and other stock-based awards, but any such dividend equivalents will be subject to the same restrictions and risk of forfeiture as the underlying units or other share equivalents to which such dividend equivalents relate.
Performance Awards. A performance award is an award of shares of common stock or units that are only earned if certain conditions are met. Any award under the 2022 Plan may be granted as a performance-based award if the Committee establishes one or more measures of corporate, business unit, or individual performance that must be attained, and the performance period over which the specified performance is to be attained, as a condition to the vesting, exercisability, lapse of restrictions, and/or settlement in cash or shares of the award. The Committee will determine the extent to which performance goals have been attained and other applicable terms and conditions have been satisfied and the degree to which vesting, exercisability, lapse of restrictions, and/or settlement in cash or shares of a performance award has been earned. The Committee may provide for the payment of dividend equivalents on performance-based awards, but any dividend equivalents will be subject to the same restrictions as the awards are. The Committee also has the ability to provide, in an individual award agreement or elsewhere, for the modification of a performance period and/or an adjustment or waiver of the achievement of performance goals upon the occurrence of certain events, which may include a change in control, a corporate transaction, a recapitalization, a change in the accounting practices of our company, or a participant’s death or disability.
Other Stock- and Cash-Based Awards. The Committee may grant awards of cash-based incentives, common stock and other awards that are valued by reference to and/or payable in shares of our common stock, or without reference to our common stock under the 2022 Plan. The Committee has discretion in determining the terms and conditions of such awards.
Vesting. The Plan allows for awards subject to either time-based vesting or performance-based vesting, or both.
Transferability of Awards. In general, no right or interest in any award under the 2022 Plan may be assigned, transferred, exchanged or encumbered by a participant, voluntarily or involuntarily, except by will or the laws of descent and distribution. However, the Committee may provide that an award (other than an incentive stock option) may be transferable by gift to a participant’s family member or pursuant to a domestic relations order. Any permitted transferee of such an award will remain subject to all the terms and conditions of the award applicable to the participant.

TABLE OF CONTENTS

Corporate Transactions; Change in Control. If a change in control occurs which is a corporate transaction, the Committee may, in its discretion, provide for one or more of the following with respect to awards under the 2022 Plan: (i) the continuation, assumption or replacement of outstanding awards; (ii) the acceleration of the vesting and exercisability of outstanding awards, in whole or in part, upon a change in control, or upon termination of a participant’s employment or other service under specified conditions within a specified period of time after the change in control; or (iii) the cancellation of awards in exchange for payment to participants in cash, shares or other consideration equal to the difference, if any, between the fair market value of the consideration that would be received in the corporate transaction for the number of shares subject to the award and the aggregate exercise price (if any) of the shares subject to the award. In the case of performance awards, in the event of a change in control, the Committee will determine to what extend the goals and other conditions have been met.
If a change in control occurs which is not a corporate transaction, the Committee may: (i) fully accelerate the vesting and exercisability of outstanding awards, upon the change in control, or upon termination of a participant’s employment or other service under specified conditions within a specified period of time after the change in control; (ii) extend the exercisability of an option or SAR; or (iii) cancel awards in exchange for payment to participants in cash, shares or other consideration.
The Committee may specify the action to be taken in an award agreement or may take the action prior to or coincident with the change in control and is not required to treat all awards or all participants similarly.
In the event of a dissolution or liquidation of our company, all outstanding awards will terminate.
For purposes of the 2022 Plan, the following terms have the meanings indicated:

• | A “corporate transaction” generally means (i) a sale or other disposition of all or substantially all of the assets of the Company, or (ii) a reorganization, merger, consolidation, share exchange or similar transaction involving the Company.

• | A “change in control” generally refers to a corporate transaction (as defined above), the acquisition by a person or group of beneficial ownership of 50% or more of the voting power of our stock, or our “continuing directors” ceasing to constitute a majority of our board.

Effect of Termination of Service. Unless otherwise set forth in an applicable agreement, if a participant’s employment or other service relationship with us and our subsidiaries is terminated, the 2022 Plan provides that unvested portions of his or her outstanding awards will be forfeited, and vested portions of outstanding option and SAR awards will continue to be exercisable for a period of three months after termination, unless the termination is for cause. In the event of a termination for “cause,” the vested but unexercised portions of options and SAR awards will also be terminated. “Cause” for termination is defined in any applicable employment agreement, or otherwise generally involves unsatisfactory performance of duties, violation of law, failure to comply with our policies or agreements with the participant, personal dishonesty, or conduct which may bring harm to our company. Upon termination due to death or disability, all outstanding awards will become fully vested, and the option and SAR awards may be exercised for a period of one year after the date of termination.
Parachute Payments. In the event that the benefits provided for in the 2022 Plan or otherwise payable to a participant constitute Section 280G “parachute payments” and would be subject to excise taxes, then such pay and benefits will be either be delivered in full or delivered as to such lesser extent which would result in no portion of such pay or benefits being subject to excise taxes, whichever results in the receipt by the participant of the greatest amount of benefits.
Effective Date of Plan Amendment. The amended 2022 Plan will become effective on the date that this proposal is approved by the Company’s shareholders. If our shareholders do not approve this proposal, the amendment to the 2022 Plan will not take effect and the 2022 Plan will continue under its original terms.
Term of the 2022 Plan. Unless terminated earlier, the 2022 Plan will terminate on August 29, 2032. Awards outstanding under the 2022 Plan at the time it is terminated will continue in accordance with their terms and the terms of the 2022 Plan unless otherwise provided in the applicable agreements.
Amendment or Termination of the Plan. The board of directors may amend or terminate the 2022 Plan from time to time. However, except in the case of adjustments upon changes in common stock, no amendment will be effective unless approved by the shareholders of the Company to the extent shareholder approval is necessary to satisfy applicable laws or the rules of the New York Stock Exchange. Termination, suspension or amendment of the 2022 Plan may not adversely affect any outstanding award without the consent of the affected participant.

TABLE OF CONTENTS

U.S. Federal Income Tax Consequences
The following is a summary of the principal United States federal income tax consequences to the Company and to participants subject to U.S. taxation with respect to awards granted under the 2022 Plan, based on current statutes, regulations and interpretations.
Non-qualified Stock Options. If a participant is granted a non-qualified stock option under the 2022 Plan, the participant will not recognize taxable income upon the grant of the option. Generally, the participant will recognize ordinary income at the time of exercise in an amount equal to the difference between the fair market value of the shares acquired at the time of exercise and the exercise price paid. The participant’s basis in the common stock for purposes of determining gain or loss on a subsequent sale or disposition of such shares generally will be the fair market value of our common stock on the date the option was exercised. Any subsequent gain or loss will be taxable as a capital gain or loss. The Company will generally be entitled to a federal income tax deduction at the time and for the same amount as the participant recognizes as ordinary income.
Incentive Stock Options. If a participant is granted an incentive stock option under the 2022 Plan, the participant will not recognize taxable income upon grant of the option. Additionally, if applicable holding period requirements (a minimum of two years from the date of grant and one year from the date of exercise) are met, the participant will not recognize taxable income at the time of exercise. However, the excess of the fair market value of the shares acquired at the time of exercise over the aggregate exercise price is an item of tax preference income potentially subject to the alternative minimum tax. If shares acquired upon exercise of an incentive stock option are held for the holding period described above, the gain or loss (in an amount equal to the difference between the fair market value on the date of sale and the exercise price) upon disposition of the shares will be treated as a long-term capital gain or loss, and the Company will not be entitled to any deduction. Except in the event of death, if the holding period requirements are not met, the incentive stock option will be treated as one that does not meet the requirements of the Code for incentive stock options and the tax consequences described for nonqualified stock options will generally apply.
Other Awards. The current federal income tax consequences of other awards authorized under the 2022 Plan generally follow certain basic patterns. An award of restricted stock results in income recognition by a participant in an amount equal to the fair market value of the shares received at the time the restrictions lapse and the shares vest, unless the participant elects under Code Section 83(b) to accelerate income recognition and the taxability of the award to the date of grant. Stock unit awards generally result in income recognition by a participant at the time payment of such an award is made in an amount equal to the amount paid in cash or the then-current fair market value of the shares received, as applicable. SAR awards result in income recognition by a participant at the time such an award is exercised in an amount equal to the amount paid in cash or the then-current fair market value of the shares received by the participant, as applicable. In each of the foregoing cases, the Company will generally have a corresponding deduction at the time the participant recognizes ordinary income, subject to Code Section 162(m) with respect to covered employees.
Excess Parachute Payments. Code Section 280G limits the deduction that the employer may take for otherwise deductible compensation payable to certain individuals if the compensation constitutes an “excess parachute payment.” Excess parachute payments arise from payments made to disqualified individuals that are in the nature of compensation and are contingent on changes in ownership or control of the employer or certain affiliates. Accelerated vesting or payment of awards under the 2022 Plan upon a change in control our company or its affiliates could result in excess parachute payments. In addition to the deduction limitation applicable to the employer, a disqualified individual receiving an excess parachute payment is subject to a 20% excise tax on the amount thereof.
Section 409A of the Code. The foregoing discussion of tax consequences of awards under the 2022 Plan assumes that the award discussed is either not considered a “deferred compensation arrangement” subject to Section 409A of the Code, or has been structured to comply with its requirements. If an award is considered a deferred compensation arrangement subject to Section 409A but fails to comply, in operation or form, with the requirements of Section 409A, the affected participant would generally be required to include in income when the award vests the amount deemed “deferred,” would be required to pay an additional 20% income tax on such amount, and would be required to pay interest on the tax that would have been paid but for the deferral.
Section 162(m) and Limits on our Company’s Deductions. Section 162(m) of the Code denies deductions to publicly held corporations for compensation paid to certain senior executives that exceeds $1,000,000.
Awards Under the 2022 Plan
Because all awards under the 2022 Plan are discretionary with the Committee, neither the number nor types of future 2022 Plan awards to be received by or allocated to particular participants or groups of participants is presently determinable.

3. | require nominating shareholders to disclose limited partners or business associates, except to the extent such investors own more than 5% of the Company’s shares.

Supporting Statement
Under SEC Rule 14a-19, the universal proxy card must include all director nominees presented by management and shareholders for election.1 Although the Rule implies each side’s nominees must be grouped together and clearly identified as such, in a fair and impartial manner, most rules for director elections are set in company bylaws.
For Rule 14a-19 to be implemented equitably, boards must not undertake bylaw amendments that deter legitimate efforts by shareholders to submit nominees. The bylaw amendments set forth in the proposed resolution would presumptively deter legitimate use of Rule 14a-19 by deterring legitimate efforts by shareholders to seek board representation through a proxy contest.
The power to amend bylaws is shared by directors and shareholders. Although directors have the power to adopt bylaw amendments, shareholders have the power to check that authority by repealing board-adopted bylaws. Directors should not amend the bylaws in ways that inequitably restrict shareholders’ right to nominate directors. This resolution simply asks the board to commit not to amend the bylaws to deter legitimate efforts to seek board representation, without submitting such amendments to shareholders. We urge the Board not to further amend its advance notice bylaws until shareholders have at least voted on this proposal.
Bloomberg’s Matt Levine speculates bylaws might require disclosure submissions “on paper woven from unicorns’ manes,”2 with requirements waived for the board’s nominees. While Mr. Levine depicts humorous and exaggerated possibilities, some companies are adopting amendments clearly designed to discourage fair elections.
Directors of at least one company (Masimo Corp.) recently adopted bylaw amendments that could deter legitimate efforts by shareholders to seek board representation through a proxy contest. Masimo’s advance notice bylaws “resemble the ‘nuclear option’ and offers a case study in how rational governance devices can become unduly weaponized, writes Lawrence Cunningham.3 Directors of other companies are considering similar proposals.
To ensure shareholders can vote on any proposal that would impose inequitable restrictions, we urge a vote FOR Fair Elections.

TABLE OF CONTENTS

THE BOARD OF DIRECTORS RECOMMENDS AGAINST THIS PROPOSAL
Our Board of Directors has carefully considered the above proposal, believes it is not in the best interests of the Company and our shareholders for the reasons set forth below, and recommends that shareholders vote against the proposal.
The Company’s advance-notice Bylaws are aligned with mainstream practices to ensure an informed shareholder vote and do not deter legitimate efforts to seek board representation.
The Company recently amended its Bylaws in light of SEC Rule 14a-19, taking a measured, balanced approach. Unlike the company referenced in the Supporting Statement (Masimo Corp.), the Company’s Bylaws do not include any provisions that would deter legitimate efforts by shareholders to seek board representation. The Company has no history of provisions or attempts to entrench its board and, in fact, is aligned with the mainstream with respect to its advance-notice Bylaws.
The first prong of the proposal would require shareholder approval for any advance-notice bylaw amendments that require the nomination of candidates more than 90 days before the annual meeting. This aspect of the proposal suggests that a director-nomination deadline of more than 90 days before the annual meeting is on its face unfair to shareholders. The Supporting Statement states: “The bylaw amendments set forth in the proposed resolution would presumptively deter legitimate use of Rule 14a-19 by deterring legitimate efforts by shareholders to seek board representation through a proxy contest. [...] Directors of at least one company (Masimo Corp.) recently adopted bylaw amendments that could deter legitimate efforts by shareholders to seek board representation through a proxy contest. [...] Directors of other companies are considering similar proposals.”
The Company’s Bylaws currently include standard advance-notice requirements, which provide that nominations by shareholders, other than those pursuant to our proxy-access provision, must be made pursuant to notice received at least 90 days prior to the first anniversary of the preceding year’s annual meeting. While the Company’s Board currently has no intention of extending this advance-notice period, it is not out of the question that circumstances could arise in the future warranting such a change. For example, regulatory changes may occur or governance best practices may evolve. If the Company’s Bylaws were amended to require shareholder approval for such a change, shareholder approval would extend the time period for implementing this change by a number of weeks, if not months. It is possible this delay may prevent the extension from being implemented on a timely basis which is an unnecessary risk to take on given the Board’s long track record of always approaching governance matters in a measured and balanced manner. Maintaining the flexibility typically given to boards of directors with respect to bylaw amendments is a much more prudent approach given the Company’s governance profile and the uncertainty as to the potential impact of this change if unintended circumstances occur.
The Board must maintain the ability to obtain sufficient information regarding director candidates and nominating shareholders to provide full and fair shareholder disclosure regarding nominees and their potential conflicts of interests.
The remainder of the proposal would require shareholder approval for any advance-notice bylaw amendments that “impose new disclosure requirements for director nominees, including disclosures related to past and future plans” or that would “require nominating shareholders to disclose limited partners or business associates, except to the extent such investors own more than 5% of the Company’s shares.” The Supporting Statement refers to requirements that “inequitably restrict shareholders’ right to nominate directors.” However, the language in the proposal is not specific enough to be limited to “inequitable” disclosure requirements, and instead captures disclosure requirements mandated by law or by legitimate shareholder concerns. In fact, the proposal would significantly limit the Board’s flexibility to respond to changing circumstances, laws, and regulations and thus may hinder the Board’s ability to require full and fair shareholder disclosure regarding director nominees and their potential conflicts of interest.
The Company may need to act quickly to impose new requirements for the nomination of director candidates, including to comply with applicable law or as the directors, in their capacities as fiduciaries for the Company, determine is in the best interest of the Company and our shareholders. If there is a change in law (e.g., new sanctions, antitrust laws or securities regulations) that requires new disclosure for director candidates, the Board would need to be able to quickly amend the Bylaws to impose new requirements in order to comply with the law.
The Company already collects information from director nominees and nominating shareholders for a variety of reasons, including pursuant to legal requirements – whether statutory or in order to ensure that the Company does not appoint a director who, for example, is conflicted or whose serving as a director may cause the Company
|65

TABLE OF CONTENTS

to violate state laws or federal statutes such as the Clayton Act. It is entirely conceivable that a change in federal or state law will require public companies to collect new information from director nominees or nominating shareholders, and if the proposal were to be approved and implemented, the Company may not be able to comply with that law.
In addition, changes in the structure of ownership or management of entities that make director nominations may require the Board to solicit additional information regarding a nominating shareholder, even under current laws and regulations. Similarly, existing laws, regulations and best practices include full and fair disclosure to the Company’s shareholders regarding director candidates and their potential conflicts of interest, and therefore the Board needs to retain sufficient flexibility to request complete information about such matters from director nominees, which could be significantly restricted if the proposal were implemented. The Company has a level playing field with respect to director nominees and only requests from shareholder nominees what it requests of its own nominees. The Board has no intention of changing this framework.
Accordingly, our Board of Directors believes the proposal is not in the best interests of the Company and its shareholders and recommends that shareholders vote against the proposal.

(1) determining the Service Providers to whom Awards will be granted, the timing of each such Award, the types of Awards and the number of Shares or amount of cash covered by each Award, the terms, conditions, performance criteria, restrictions and other provisions of Awards, and the manner in which Awards are paid or settled;

A-4|

TABLE OF CONTENTS

(4) taking such actions as are described in Section 3(c) with respect to Awards to Global Service Providers.
(c)Awards to Global Service Providers. The Committee may grant Awards to Global Service Providers, on such terms and conditions different from those specified in the Plan as may, in the judgment of the Committee, be necessary or desirable to comply with applicable foreign laws and regulatory requirements and to promote achievement of the purposes of the Plan. In connection therewith, the Committee may establish such subplans or annexes to Award Agreements and may modify exercise procedures and other Plan rules and procedures to the extent such actions are deemed necessary or desirable, and may take any other action that it deems advisable to obtain local regulatory approvals or to comply with any necessary local governmental regulatory exemptions.
(d)Acts of the Committee; Delegation. A majority of the members of the Committee shall constitute a quorum for any meeting of the Committee, and any act of a majority of the members present at any meeting at which a quorum is present or any act unanimously approved in writing by all members of the Committee shall be the act of the Committee. Any such action of the Committee shall be valid and effective even one or more of the members of the Committee at the time of such action are later determined not to have satisfied all of the criteria for membership in clauses (i) or (ii) of Section 2(j). To the extent not inconsistent with applicable law or stock exchange rules, the Committee may delegate all or any portion of its authority under the Plan to any one or more of its members or, as to Awards to Participants who are not subject to Section 16 of the Exchange Act, to one or more directors or executive officers of the Company, or to a committee of the Board comprised of one or more directors of the Company. The Committee may also delegate non-discretionary administrative responsibilities in connection with the Plan to such other persons as it deems advisable.
(e)Finality of Decisions. The Committee’s interpretation of the Plan and of any Award or Agreement made under the Plan and all related decisions or resolutions of the Board or Committee shall be final and binding on all parties with an interest therein.
(f)Indemnification. Each person who is or has been a member of the Committee or of the Board, and any other person to whom the Committee delegates authority under the Plan, shall be indemnified by the Company, to the maximum extent permitted by law, against liabilities and expenses imposed upon or reasonably incurred by such person in connection with or resulting from any claims against such person by reason of the performance of the individual’s duties under the Plan. This right to indemnification is conditioned upon such person providing the Company an opportunity, at the Company’s expense, to handle and defend the claims before such person undertakes to handle and defend them on such person’s own behalf. The Company will not be required to indemnify any person for any amount paid in settlement of a claim unless the Company has first consented in writing to the settlement. The foregoing right of indemnification shall not be exclusive of any other rights of indemnification to which such person or persons may be entitled under the Company’s Articles of Incorporation or Bylaws, as a matter of law, or otherwise.
4.Shares Available Under the Plan.
(a)Maximum Shares Available. Subject to the provisions of this Section 4 and to adjustment as provided in Section 12(a), the number of Shares that may be the subject of Awards and issued under the Plan shall be 1,795,500 plus any Shares subject to outstanding awards under the Prior Plan that expire, are cancelled, or are otherwise forfeited. Shares to be issued under the Plan shall be authorized and unissued Shares. In determining the number of Shares to be counted against this share reserve in connection with any Award, the following rules shall apply:
(1) Where the number of Shares subject to an Award is variable on the Grant Date, the number of Shares to be counted against the share reserve shall be the maximum number of Shares that could be received under that particular Award, until such time as it can be determined that only a lesser number of shares could be received.
|A-5

TABLE OF CONTENTS

(2) Where two or more types of Awards are granted to a Participant in tandem with each other, such that the exercise of one type of Award with respect to a number of Shares cancels at least an equal number of Shares of the other, the number of Shares to be counted against the share reserve shall be the largest number of Shares that would be counted against the share reserve under either of the Awards.
(3) Shares subject to Substitute Awards shall not be counted against the share reserve, nor shall they reduce the Shares authorized for grant to a Participant in any calendar year.
(4) Awards that may be settled solely in cash shall not be counted against the share reserve, nor shall they reduce the Shares authorized for grant to a Participant in any calendar year.
(b)Effect of Forfeitures and Other Actions. Any Shares subject to an Award, or to an award granted under the Prior Plan that is outstanding on the effective date of this Plan (a “Prior Plan Award”), that is cancelled, expires or forfeited or is settled for cash shall, to the extent of such cancellation, forfeiture, expiration or cash settlement, again become available for Awards under this Plan, the share reserve under Section 4(a) shall be correspondingly replenished as provided in Section 4(c) below. The following Shares shall not, however, again become available for Awards or replenish the share reserve under Section 4(a): (i) Shares tendered (either actually or by attestation) by the Participant or withheld by the Company in payment of the exercise price of a stock option issued under this Plan or the Prior Plan, (ii) Shares tendered (either actually or by attestation) by the Participant or withheld by the Company to satisfy any tax withholding obligation with respect to an Award or Prior Plan Award, (iii) Shares repurchased by the Company with proceeds received from the exercise of an option issued under this Plan or the Prior Plan, and (iv) Shares subject to a stock appreciation right award issued under this Plan or the Prior Plan that are not issued in connection with the stock settlement of that Award upon its exercise.
(c)Counting Shares Again Available. Each Share that again becomes available for Awards as provided in Section 4(b) shall correspondingly increase the share reserve under Section 4(a), with such increase based on the same share ratio by which the applicable share reserve was decreased upon the grant of the applicable award.
(d)Effect of Plans Operated by Acquired Companies. If a company acquired by the Company or any Subsidiary or with which the Company or any Subsidiary combines has shares available under a pre-existing plan approved by shareholders and not adopted in contemplation of such acquisition or combination, the shares available for grant pursuant to the terms of such pre-existing plan (as adjusted, to the extent appropriate, using the exchange ratio or other adjustment or valuation ratio or formula used in such acquisition or combination to determine the consideration payable to the holders of common stock of the entities party to such acquisition or combination) may be used for Awards under the Plan and shall supplement the share reserve under Section 4(a). Awards using such available shares shall not be made after the date awards or grants could have been made under the terms of the pre-existing plan, absent the acquisition or combination, and shall only be made to individuals who were not Employees or Non-Employee Directors prior to such acquisition or combination.
(e)No Fractional Shares. Unless otherwise determined by the Committee, the number of Shares subject to an Award shall always be a whole number. No fractional Shares may be issued under the Plan, but the Committee may, in its discretion, adopt any rounding convention it deems suitable or pay cash in lieu of any fractional Share in settlement of an Award.
(f)Limits on Awards to Non-Employee Directors. The aggregate grant date fair value (as determined in accordance with generally accepted accounting principles applicable in the United States) of all Awards granted during any calendar year to any Non-Employee Director, together with the amount of any cash fees or retainers paid to such Non-Employee Director during such calendar year with respect to such individual’s Service as a Non-Employee Director shall not exceed $750,000.
5.Eligibility. Participation in the Plan is limited to Service Providers. Incentive Stock Options may only be granted to Employees who are not Global Service Providers.

TABLE OF CONTENTS

6.General Terms of Awards.
(a)Award Agreement. Except for any Award that involves only the immediate issuance of unrestricted Shares, each Award shall be evidenced by an Agreement setting forth the number of Shares subject to the Award together with such other terms and conditions applicable to the Award (and not inconsistent with the Plan) as determined by the Committee. If an Agreement calls for acceptance by the Participant, the Award evidenced by the Agreement will not become effective unless acceptance of the Agreement in a manner permitted by the Committee is received by the Company within 30 days of the date the Agreement is delivered to the Participant. An Award to a Participant may be made singly or in combination with any form of Award. Two types of Awards may be made in tandem with each other such that the exercise of one type of Award with respect to a number of Shares reduces the number of Shares subject to the related Award by at least an equal amount.
(b)Vesting and Term. Each Agreement shall set forth the period until the applicable Award is scheduled to vest and, if applicable, expire (which shall not be more than ten years from the Grant Date), and consistent with the requirements of this Section 6, the applicable vesting conditions and any applicable performance period. The Committee may provide in an Agreement for such vesting conditions as it may determine. Unless the Committee provides otherwise, the vesting of Awards granted hereunder will continue to vest during any unpaid leave of absence.
(c)Transferability. Except as provided in this Section 6(c), (i) during the lifetime of a Participant, only the Participant or the Participant’s guardian or legal representative may exercise an Option or SAR, or receive payment with respect to any other Award; and (ii) no Award may be sold, assigned, transferred, exchanged or encumbered, voluntarily or involuntarily, other than by will or the laws of descent and distribution. Any attempted transfer in violation of this Section 6(c) shall be of no effect. The Committee may, however, provide in an Agreement or otherwise that an Award (other than an Incentive Stock Option) may be transferred pursuant to a domestic relations order or may be transferable by gift to any “family member” (as defined in General Instruction A(1)(a)(5) to Form S-8 under the Securities Act of 1933) of the Participant. Any Award held by a transferee shall continue to be subject to the same terms and conditions that were applicable to that Award immediately before the transfer thereof. For purposes of any provision of the Plan relating to notice to a Participant or to acceleration or termination of an Award upon the death or termination of Service of a Participant, the references to “Participant” shall mean the original grantee of an Award and not any transferee.
(d)Designation of Beneficiary. The Committee may permit each Participant to designate a beneficiary or beneficiaries to exercise any Award or receive a payment under any Award that is exercisable or payable on or after the Participant’s death. Any such designation shall be on a written or electronic form approved by the Committee and shall be effective upon its receipt by the Company or an agent selected by the Company.
(e)Termination of Service. Unless otherwise provided in an Agreement, and subject to Sections 6(i) and 12 of this Plan, if a Participant’s Service with the Company and all of its Affiliates terminates, the following provisions shall apply (in all cases subject to the originally scheduled expiration of an Option or Stock Appreciation Right Award, as applicable):
(1) Upon termination of Service for Cause, or upon conduct during a post-termination exercise period that would constitute Cause, all unexercised Options and SARs and all unvested portions of any other outstanding Awards shall be immediately forfeited without consideration.
(2) Upon termination of Service due to death or Disability, any unvested portion of an Award shall immediately become vested (and exercisable, if applicable), and the vested and exercisable portions of Options or SARs may be exercised for a period of twelve months after the date of such termination and shall terminate upon the expiration of such period.
(3) Upon a termination of Service for any reason other than Cause, death or Disability, all unvested and unexercisable portions of any outstanding Awards shall be immediately forfeited without consideration, but the currently vested and exercisable portions of Options
|A-7

TABLE OF CONTENTS

and SARs may be exercised for a period of three months after the date of such termination and shall, subject to the following sentence, terminate upon the expiration of such period. However, if a Participant dies during such three-month post-termination exercise period, then the applicable post-termination exercise period shall be extended to twelve months after the date of such termination.
(f)Rights as Shareholder. No Participant shall have any rights as a shareholder with respect to any Shares covered by an Award unless and until the date the Participant becomes the holder of record of the Shares, if any, to which the Award relates.
(g)Performance-Based Awards. Any Award may be granted as Performance-Based Award if the Committee establishes one or more measures of corporate, Subsidiary, business unit or individual performance which must be attained, and the performance period over which the specified performance is to be attained, as a condition to the grant, vesting, exercisability, lapse of restrictions and/or settlement in cash or Shares of such Award. In connection with any such Award, the Committee shall determine the extent to which performance measures have been attained and other applicable terms and conditions have been satisfied, and the degree to which the grant, vesting, exercisability, lapse of restrictions and/or settlement of such Award has been earned. Any Performance-Based Award shall additionally be subject to the requirements of Section 17 of this Plan. Except as provided in Section 17 with respect to Performance-Based Award, the Committee shall also have the authority to provide, in an Agreement or otherwise, for the modification of a performance period and/or an adjustment or waiver of the achievement of performance goals upon the occurrence of events that are unusual in nature or infrequently occurring, such as a Change of Control, a Corporate Transaction, an equity restructuring, a recapitalization, a divestiture, a change in the accounting practices of the Company, or the Participant’s death or Disability.
(h)Dividends and Dividend Equivalents. Any dividends, dividend equivalents or distributions paid with respect to Shares that are subject to the unvested portion of an Award will be subject to the same restrictions as the Shares to which such dividends or distributions relate. No dividends, dividend equivalents or distributions will be paid with respect to Shares subject to an Option or SAR Award. In its discretion, the Committee may provide in an Agreement for a Stock Unit Award or an Other Stock-Based Award that the Participant will be entitled to receive dividend equivalents on the units or other Share equivalents subject to the Award based on dividends actually declared and paid on outstanding Shares. Dividends and dividend equivalents on Performance-Based Awards will be subject to the same terms and conditions, including vesting conditions and the achievement of any applicable performance goals, as the original Award. The additional terms of any such dividend equivalents will be as set forth in the applicable Award Agreement, including any additional restrictions and whether such dividend equivalents will be credited with interest or deemed to be reinvested in additional units or Share equivalents. Any Shares issued or issuable during the term of this Plan as the result of the reinvestment of dividends or the deemed reinvestment of dividend equivalents in connection with an Award or a Prior Plan Award shall be counted against, and replenish upon any subsequent forfeiture, the Plan’s share reserve as provided in Section 4.
(i)Extension of Termination Date. If a Participant would otherwise be precluded from exercising an Option or SAR prior to the expiration of its scheduled term or prior to its termination following the termination of the Participant’s Service solely because the issuance of the Shares upon such exercise would violate applicable registration requirements under the Securities Act, then the Committee may provide that the period during which the Option or SAR may be exercised and the termination date of the Option or SAR shall be extended until the later of (i) the date that is 30 days after the exercise of the Option or SAR would no longer violate the registration requirements of the Securities Act, or (ii) the end of the applicable post-termination exercise period, but in no event later than the scheduled expiration date of the Option as set forth in the applicable Agreement.

7.Stock Option Awards.
(a)Type and Exercise Price. The Agreement pursuant to which an Option is granted shall specify whether the Option is an Incentive Stock Option or a Non-Statutory Stock Option. The exercise price at which each Share subject to an Option may be purchased shall be determined by the Committee and set forth in the Agreement, and shall not be less than the Fair Market Value of a Share on the Grant Date, except in the case of Substitute Awards (to the extent consistent with Code Section 409A and, in the case of Incentive Stock Options, Code Section 424).
(b)Payment of Exercise Price. The purchase price of the Shares with respect to which an Option is exercised shall be payable in full at the time of exercise. The purchase price may be paid in cash or in such other manner as the Committee may permit, including by payment under a broker-assisted sale and remittance program acceptable to the Committee or by withholding Shares otherwise issuable to the Participant upon exercise of the Option or by delivery to the Company of Shares (by actual delivery or attestation) already owned by the Participant (in each case, such Shares having a Fair Market Value as of the date the Option is exercised equal to the purchase price of the Shares being purchased).
(c)Exercisability and Expiration. Each Option shall be exercisable in whole or in part on the terms provided in the Agreement. No Option shall be exercisable at any time after its scheduled expiration. When an Option is no longer exercisable, it shall be deemed to have terminated.
(d)Incentive Stock Options.
(1) An Option will constitute an Incentive Stock Option only if the Participant receiving the Option is an Employee who is not a Global Service Provider, and only to the extent that (i) it is so designated in the applicable Agreement and (ii) the aggregate Fair Market Value (determined as of the Option’s Grant Date) of the Shares with respect to which Incentive Stock Options held by the Participant first become exercisable in any calendar year (under the Plan and all other plans of the Company and its Affiliates) does not exceed $100,000. To the extent an Option granted to a Participant exceeds this limit, the Option shall be treated as a Non-Statutory Stock Option. The maximum number of Shares that may be issued upon the exercise of Incentive Stock Options shall equal the maximum number of Shares that may be the subject of Awards and issued under the Plan as provided in the first sentence of Section 4(a) subject to adjustment as provided in Section 12(a).
(2) No Participant may receive an Incentive Stock Option under the Plan if, immediately after the grant of such Award, the Participant would own (after application of the rules contained in Code Section 424(d)) Shares possessing more than 10% of the total combined voting power of all classes of stock of the Company or an Affiliate, unless (i) the option price for that Incentive Stock Option is at least 110% of the Fair Market Value of the Shares subject to that Incentive Stock Option on the Grant Date and (ii) that Option will expire no later than five years after its Grant Date.
(3) For purposes of continued Service by a Participant who has been granted an Incentive Stock Option, no approved leave of absence may exceed three months unless reemployment upon expiration of such leave is provided by statute or contract. If reemployment is not so provided, then on the date six months following the first day of such leave, any Incentive Stock Option held by the Participant shall cease to be treated as an Incentive Stock Option and shall be treated for tax purposes as a Non-Statutory Stock Option.
(4) If an Incentive Stock Option is exercised after the expiration of the exercise periods that apply for purposes of Code Section 422, or otherwise fails to qualify as an Incentive Stock Option, such Option shall thereafter be treated as a Non-Statutory Stock Option.
(5) The Agreement covering an Incentive Stock Option shall contain such other terms and provisions that the Committee determines necessary to qualify the Option as an Incentive Stock Option.
|A-9

8.Stock Appreciation Rights.
(a)Nature of Award. An Award of Stock Appreciation Rights shall be subject to such terms and conditions as are determined by the Committee, and shall provide a Participant the right to receive upon exercise of the SAR all or a portion of the excess of (i) the Fair Market Value as of the date of exercise of the SAR of the number of Shares as to which the SAR is being exercised, over (ii) the aggregate exercise price for such number of Shares. The per Share exercise price for any SAR Award shall be determined by the Committee and set forth in the applicable Agreement, and shall not be less than the Fair Market Value of a Share on the Grant Date, except in the case of Substitute Awards (to the extent consistent with Code Section 409A).
(b)Exercise of SAR. Each SAR may be exercisable in whole or in part at the times, on the terms and in the manner provided in the Agreement. No SAR shall be exercisable at any time after its scheduled expiration. When a SAR is no longer exercisable, it shall be deemed to have terminated. Upon exercise of a SAR, payment to the Participant shall be made at such time or times as shall be provided in the Agreement in the form of cash, Shares or a combination of cash and Shares as determined by the Committee. The Agreement may provide for a limitation upon the amount or percentage of the total appreciation on which payment (whether in cash and/or Shares) may be made in the event of the exercise of a SAR.
9.Restricted Stock Awards.
(a)Vesting and Consideration. Shares subject to a Restricted Stock Award shall be subject to vesting conditions, and the corresponding lapse of forfeiture conditions and other restrictions, based on such factors and occurring over such period of time as the Committee may determine in its discretion. The Committee may provide whether any consideration other than Services must be received by the Company or any Affiliate as a condition precedent to the grant of a Restricted Stock Award, and may correspondingly provide for Company reacquisition or repurchase rights if such additional consideration has been required and some or all of a Restricted Stock Award does not vest.
(b)Shares Subject to Restricted Stock Awards. Unvested Shares subject to a Restricted Stock Award shall be evidenced by a book-entry in the name of the Participant with the Company’s transfer agent or by one or more Stock certificates issued in the name of the Participant. Any such Stock certificate shall be deposited with the Company or its designee, together with an assignment separate from the certificate, in blank, signed by the Participant, and bear an appropriate legend referring to the restricted nature of the Restricted Stock evidenced thereby. Any book-entry shall be subject to transfer restrictions and accompanied by a similar legend. Upon the vesting of Shares of Restricted Stock and the corresponding lapse of the restrictions and forfeiture conditions, and any necessary conditions precedent to the release of vested Shares (such as satisfaction of tax withholding obligations) have been satisfied, the corresponding transfer restrictions and restrictive legend will be removed from the book-entry evidencing such Shares or the certificate evidencing such Shares, and any such certificate shall be delivered to the Participant. Such vested Shares may, however, remain subject to additional restrictions as provided in Section 18(c). Except as otherwise provided in the Plan or an applicable Agreement, a Participant with a Restricted Stock Award shall have all the rights of a shareholder, including the right to vote the Shares of Restricted Stock.
10.Stock Unit Awards.
(a)Vesting and Consideration. A Stock Unit Award shall be subject to vesting conditions, and the corresponding lapse of forfeiture conditions and other restrictions, based on such factors and occurring over such period of time as the Committee may determine in its discretion. If a Stock Unit Award is a Performance-Based Award, the extent to which the goals are achieved over the specified performance period shall determine the number of Stock Units that will be earned and eligible to vest, which may be greater or less than the target number of Stock Units stated in the Agreement. The Committee may provide whether any consideration other than Services must be received by the Company or any Affiliate as a condition precedent to the settlement of a Stock Unit Award.
A-10|

TABLE OF CONTENTS

(b)Settlement of Award. Following the vesting of a Stock Unit Award, and the Committee’s determination that any necessary conditions precedent to the settlement of the Award (such as satisfaction of tax withholding obligations and compliance with applicable legal requirements) have been satisfied, settlement of the Award and payment to the Participant shall be made at such time or times in the form of cash, Shares (which may themselves be considered Restricted Stock under the Plan subject to restrictions on transfer and forfeiture conditions) or a combination of cash and Shares as determined by the Committee.
11.Cash-Based and Other Stock-Based Awards.
(a)Cash Incentive Awards. A Cash Incentive Award may be considered a Performance-Based Award, and may be granted to any Participant in such amounts and upon such terms and at such times as shall be determined by the Committee, and may be denominated in units that have a dollar value established by the Committee as of the Grant Date. Following the completion of the applicable performance period and the vesting of a Cash Incentive Award, payment of the settlement amount of the Award to the Participant shall be made at such time or times in the form of cash, Shares or other forms of Awards under the Plan (valued for these purposes at their grant date fair value) or a combination of cash, Shares and other forms of Awards as determined by the Committee and specified in the applicable Agreement.
(b)Other Stock-Based Awards. The Committee may from time to time grant Stock and other Awards that are valued by reference to and/or payable in whole or in part in Shares under the Plan. The Committee, in its sole discretion, shall determine the terms and conditions of such Awards, which shall be consistent with the terms and purposes of the Plan. The Committee may, in its sole discretion, direct the Company to issue Shares subject to restrictive legends and/or stop transfer instructions that are consistent with the terms and conditions of the Award to which the Shares relate.
12.Changes in Capitalization and Other Corporate Events.
(a)Adjustments for Changes in Capitalization. In the event of any equity restructuring (within the meaning of FASB ASC Topic 718 - Stock Compensation) that causes the per share value of Shares to change, such as a stock dividend, stock split, spinoff, rights offering or recapitalization through an extraordinary dividend, the Committee shall make such adjustments as it deems equitable and appropriate to (i) the aggregate number and kind of Shares or other securities issued or reserved for issuance under the Plan, (ii) the number and kind of Shares or other securities subject to outstanding Awards, (iii) the exercise price of outstanding Options and SARs, and (iv) any maximum limitations prescribed by the Plan with respect to certain types of Awards or the grants to individuals of certain types of Awards. In the event of any other change in corporate capitalization, including a merger, consolidation, reorganization, or partial or complete liquidation of the Company, such equitable adjustments described in the foregoing sentence may be made as determined to be appropriate and equitable by the Committee to prevent dilution or enlargement of rights of Participants. In either case, any such adjustment shall be conclusive and binding for all purposes of the Plan. No adjustment shall be made pursuant to this Section 12(a) in connection with the conversion of any convertible securities of the Company, or in a manner that would cause Incentive Stock Options to violate Section 422(b) of the Code or cause an Award to be subject to adverse tax consequences under Code Section 409A.
(b)Corporate Transactions. Unless otherwise provided in an applicable Agreement, in the event of a Change in Control that involves a Corporate Transaction, the Board or the Committee shall take one or more of the following actions with respect to outstanding Awards, which actions may vary among individual Participants and among Awards held by an individual Participant, and are conditioned in each case upon the closing or completion of the Corporate Transaction:
(1)Continuation, Assumption or Replacement of Awards. Arrange for the surviving or successor entity (or its Parent) to continue, assume or replace Awards outstanding as of the date of the Corporate Transaction (with such adjustments as may be required or permitted by Section 12(a)), and such Awards or replacements therefor to remain outstanding and be governed by their respective terms. A surviving or successor entity may elect to continue,
|A-11

TABLE OF CONTENTS

assume or replace only some Awards or portions of Awards. For purposes of this Section 12(b)(1), an Award shall be considered assumed or replaced if, in connection with the Corporate Transaction and in a manner consistent with Code Sections 409A and 424, either (i) the contractual obligations represented by the Award are expressly assumed by the surviving or successor entity (or its Parent) with appropriate adjustments to the number and type of securities subject to the Award and the exercise price thereof that preserves the intrinsic value of the Award existing at the time of the Corporate Transaction, or (ii) the Participant has received a comparable equity-based award that preserves the intrinsic value of the Award existing at the time of the Corporate Transaction and is subject to substantially similar terms and conditions as the Award.
(2)Acceleration. Accelerate the vesting (and exercisability, if applicable) of (i) some or all outstanding Options and SARs so that such Awards may be exercised in full for such limited period of time prior to the effective time of the Corporate Transaction as is deemed fair and equitable by the Board or Committee, with such Awards then terminating to the extent not exercised at the effective time of the Corporate Transaction, and (ii) some or all outstanding Full Value Awards or Cash Incentive Awards immediately prior to the effective time of the Corporate Transaction. In the case of Performance-Based Awards, the number of Shares or the amount of a Cash Incentive Award subject to such accelerated vesting shall be based on a determination by the Board or Committee of the degree to which any performance-based vesting or payment conditions will be deemed satisfied. The Board or Committee shall provide written notice of the period of accelerated exercisability of Options and SARs to all affected Participants, and any exercise of such accelerated Awards shall be conditioned upon the consummation of the Corporate Transaction and shall be effective only immediately before the effective time of the Corporate Transaction.
(3)Payment for Awards. Cancel some or all outstanding Awards at or immediately prior to the effective time of the Corporate Transaction in exchange for payments to the holders as provided in this Section 12(b)(3). The payment for any Award canceled shall be in an amount equal to the difference, if any, between (i) the fair market value (as determined in good faith by the Board or Committee) of the consideration that would otherwise be received in the Corporate Transaction for the number of Shares remaining subject to the Award, and (ii) the aggregate exercise price (if any) for the number of Shares remaining subject to such Award. If the amount determined pursuant to clause (i) of the preceding sentence is less than or equal to the amount determined pursuant to clause (ii) of the preceding sentence with respect to any Award, such Award may be canceled without payment of any kind to the affected Participant. The payment for any canceled Cash Incentive Award that was to be settled in Shares shall be in an amount equal to the settlement amount that was to form the basis for the calculation of the number of Shares to be issued. In the case of Performance-Based Awards, the number of Shares remaining subject to an Award or the settlement amount of a Cash Incentive Award shall be calculated based on a determination by the Board or Committee of the degree to which any performance-based vesting or payment conditions will be deemed satisfied. Payment of any amount under this Section 12(b)(3) shall be made in such form (including in shares of the surviving or successor entity or its Parent), on such terms and subject to such conditions as the Board or Committee determines in its discretion, which may or may not be the same as the form, terms and conditions applicable to payments to the Company’s shareholders in connection with the Corporate Transaction, and may, in the discretion of the Board or Committee, include subjecting such payments to vesting conditions comparable to those of the Award canceled, subjecting such payments to escrow or holdback terms comparable to those imposed upon the Company’s shareholders under the Corporate Transaction, or calculating and paying the present value of payments that would otherwise be subject to escrow or holdback terms.
(4)Termination After a Corporate Transaction. Provide that with respect to any Award that is continued, assumed or replaced under the circumstances described in Section 12(b)(1), if within 18 months after the Corporate Transaction the Participant experiences an involuntary termination of Service from the surviving or successor entity (or its Parent or subsidiary) for
A-12|

TABLE OF CONTENTS

reasons other than Cause, then (i) outstanding Options and SARs issued to the Participant that are not yet fully exercisable shall immediately become exercisable in full and shall remain exercisable for one year following the Participant’s termination of Service, and (ii) any Full Value Awards that are not yet fully vested shall immediately vest in full, with vesting in full for a Performance-Based Award determined as provided in Section 12(b)(2).
(5)Adjustments to Awards. Make such adjustments to some or all outstanding Awards as may be required or permitted by Sections 12(a) and 6(g).
(c)Other Change in Control. In connection with a Change in Control that does not involve a Corporate Transaction, the Board or Committee may provide (in the applicable Agreement or otherwise) for one or more of the following: (i) that any Award shall become fully vested (and exercisable, if applicable) upon the occurrence of the Change in Control or upon the involuntary termination of the Participant without Cause within 18 months of the Change in Control, (ii) that any Option or SAR shall remain exercisable during all or some specified portion of its remaining term, or (iii) that Awards shall be canceled in exchange for payments in a manner similar to that provided in Section 12(b)(3). The Committee will not be required to treat all Awards similarly in such circumstances.
(d)Dissolution or Liquidation. Unless otherwise provided in an applicable Agreement, in the event the shareholders of the Company approve the complete dissolution or liquidation of the Company, all outstanding Awards will terminate immediately prior to the consummation of any such proposed action. The Committee will notify each Participant as soon as practicable of such pending termination.
(e)Limitation on Change in Control Payments. If any payments to a Participant pursuant to Awards made under this Plan (including, for this purpose, the acceleration of the vesting and exercisability of any Award or the payment of cash or other property in exchange for all or part of any Award), taken together with any payments or benefits otherwise paid or distributed to the Participant by the Company or any corporation that is a member of an “affiliated group” (as defined in Section 1504 of the Code without regard to Section 1504(b) of the Code) of which the Company is a member (the “other arrangements”) would collectively constitute a “parachute payment” (as defined in Section 280G(b)(2) of the Code), and if the net after-tax amount of such parachute payment to the Participant is less than what the net after-tax amount to the Participant would be if the aggregate payments and benefits otherwise constituting the parachute payment were limited to three times the Participant’s “base amount” (as defined in Section 280G(b)(3) of the Code) less $1.00, then the aggregate payments and benefits otherwise constituting the parachute payment shall be reduced to an amount that shall equal three times the Participant’s base amount, less $1.00. Should such a reduction in payments and benefits be required, the Participant shall be entitled, subject to the following sentence, to designate those payments and benefits under this Plan or the other arrangements that will be reduced or eliminated (including, as applicable, a reduction in the number of Shares subject to Awards that will vest on an accelerated basis) so as to achieve the specified reduction in aggregate payments and benefits to the Participant and avoid characterization of such aggregate payments and benefits as a parachute payment. To the extent that the Participant’s ability to make such a designation would cause any of the payments and benefits to become subject to any additional tax under Code Section 409A, or if the Participant fails to make such a designation within the time prescribed by the Committee, then the Committee shall achieve the necessary reduction in such payments and benefits in the following order: (1) by reducing or eliminating the portion of the payments and benefits that are payable in cash; (2) by reducing or eliminating equity awards (or the accelerated vesting thereof) that are included as parachute payments; (3) by reducing or eliminating any non-cash, non-equity benefits; in each case, within each category, in reverse order beginning with payments and benefits which are to be paid or provided the furthest in time from the date of the Committee’s determination. For purposes of this Section 12(e), a net after-tax amount shall be determined by taking into account all applicable income, excise and employment taxes, whether imposed at the federal, state or local level, including the excise tax imposed under Section 4999 of the Code.
|A-13

TABLE OF CONTENTS

13.Plan Participation and Service Provider Status. Status as a Service Provider shall not be construed as a commitment that any Award will be made under the Plan to that Service Provider or to eligible Service Providers generally. Nothing in the Plan or in any Agreement or related documents shall confer upon any Service Provider or Participant any right to continued Service with the Company or any Affiliate, nor shall it interfere with or limit in any way any right of the Company or any Affiliate to terminate the person’s Service at any time with or without Cause or change such person’s compensation, other benefits, job responsibilities or title.
14.Tax Withholding. The Company or any Affiliate, as applicable, shall have the right to (i) withhold from any cash payment under the Plan or any other compensation owed to a Participant an amount sufficient to cover any required withholding taxes related to the grant, vesting, exercise or settlement of an Award, and (ii) require a Participant or other person receiving Shares under the Plan to pay a cash amount sufficient to cover any required withholding taxes before actual receipt of those Shares. In lieu of all or any part of a cash payment from a person receiving Shares under the Plan, the Committee may permit the individual to cover all or any part of the required withholdings (up to the Participant’s maximum individual statutory tax withholding rate) through a reduction in the number of Shares delivered or a delivery or tender to the Company of Shares held by the Participant or other person, in each case valued in the same manner as used in computing the withholding taxes under applicable laws.
15.Effective Date, Duration, Amendment and Termination of the Plan.
(a)Effective Date. The Plan became effective on the Effective Date, which is the date of its adoption for purposes of Treasury Regulation §1.422-2(b)(2)(i). No Awards shall be made under the Plan prior to its Effective Date.
(b)Duration of the Plan. The Plan shall remain in effect until all Shares subject to it shall be distributed, the Plan is terminated pursuant to Section 15(c), or the tenth anniversary of the Effective Date of the Plan, whichever occurs first (the “Termination Date”). Awards made before the Termination Date shall continue to be outstanding in accordance with their terms and the terms of the Plan unless otherwise provided in the applicable Agreements.
(c)Amendment and Termination of the Plan. The Board may at any time terminate, suspend or amend the Plan. The Company shall submit any amendment of the Plan to its shareholders for approval only to the extent required by applicable laws or regulations or the rules of any securities exchange on which the Shares may then be listed. No termination, suspension, or amendment of the Plan may materially impair the rights of any Participant under a previously granted Award without the Participant’s consent, unless such action is necessary to comply with applicable law or stock exchange rules.
(d)Amendment of Awards. Subject to Section 15(e), the Committee may unilaterally amend the terms of any Agreement previously granted, except that no such amendment may materially impair the rights of any Participant under the applicable Award without the Participant’s consent, unless such amendment is necessary to comply with applicable law or stock exchange rules or any compensation recovery policy as provided in Section 18(i)(2).
(e)No Option or SAR Repricing. Except as provided in Section 12(a), no Option or Stock Appreciation Right Award granted under the Plan may be (i) amended to decrease the exercise price thereof, (ii) cancelled in conjunction with the grant of any new Option or Stock Appreciation Right Award with a lower exercise price, (iii) cancelled in exchange for cash, other property or the grant of any Full Value Award at a time when the per share exercise price of the Option or Stock Appreciation Right Award is greater than the current Fair Market Value of a Share, or (iv) otherwise subject to any action that would be treated under accounting rules as a “repricing” of such Option or Stock Appreciation Right Award, unless such action is first approved by the Company’s shareholders.
16.Substitute Awards. The Committee may also grant Awards under the Plan in substitution for, or in connection with the assumption of, existing awards granted or issued by another corporation and assumed or otherwise agreed to be provided for by the Company pursuant to or by reason of a transaction involving a merger, consolidation, acquisition of property or stock, separation,
A-14|

TABLE OF CONTENTS

reorganization or liquidation to which the Company or an Affiliate is a party. The terms and conditions of the Substitute Awards may vary from the terms and conditions set forth in the Plan to the extent that the Committee at the time of the grant may deem appropriate to conform, in whole or in part, to the provisions of the awards in substitution for which they are granted.
17.Performance-Based Awards.
(a)Performance-Based Awards. If an Award is a Performance-Based Award, then the lapsing of restrictions thereon and the distribution of cash, Shares or other property pursuant thereto, as applicable, shall be subject to the achievement over the applicable performance period of one or more performance goals based on one or more of the performance measures specified in Section 17(b). The Committee will select the applicable performance measure(s) and specify the performance goal(s) based on those performance measures for any performance period, specify in terms of an objective formula or standard the method for calculating the amount payable to a Participant if the performance goal(s) are satisfied, and certify the degree to which applicable performance goals have been satisfied and any amount that vests and is payable in connection with an Award subject to this Section 17. In specifying the performance goals applicable to any performance period, the Committee may provide that one or more objectively determinable adjustments shall be made to the performance measures on which the performance goals are based, which may include adjustments that would cause such measures to be considered “non-GAAP financial measures” within the meaning of Rule 101 under Regulation G promulgated by the Securities and Exchange Commission, including adjustments for events that are unusual in nature or infrequently occurring, such as a Change in Control, acquisitions, divestitures, restructuring activities or asset write-downs, or for changes in applicable tax laws or accounting principles. The Committee may also adjust performance measures for a performance period in connection with an event described in Section 12(a) to prevent the dilution or enlargement of a Participant’s rights with respect to Performance-Based Award. The Committee may adjust any amount determined to be otherwise payable in connection with such an Award. The Committee may also provide, in an Agreement or otherwise, that the achievement of specified performance goals in connection with an Award subject to this Section 17 may be waived upon the death or Disability of the Participant.
18.Other Provisions.
(a)Unfunded Plan. The Plan shall be unfunded and the Company shall not be required to segregate any assets that may at any time be represented by Awards under the Plan. Neither the Company, its Affiliates, the Committee, nor the Board shall be deemed to be a trustee of any amounts to be paid under the Plan nor shall anything contained in the Plan or any action taken pursuant to its provisions create or be construed to create a fiduciary relationship between the Company and/or its Affiliates, and a Participant. To the extent any person has or acquires a right to receive a payment in connection with an Award under the Plan, this right shall be no greater than the right of an unsecured general creditor of the Company.
(b)Limits of Liability. Except as may be required by law, neither the Company nor any member of the Board or of the Committee, nor any other person participating (including participation pursuant to a delegation of authority under Section 3(c) of the Plan) in any determination of any question under the Plan, or in the interpretation, administration or application of the Plan, shall have any liability to any party for any action taken, or not taken, in good faith under the Plan.
(c)Compliance with Applicable Legal Requirements and Company Policies. No Shares distributable pursuant to the Plan shall be issued and delivered unless the issuance of the Shares complies with all applicable legal requirements, including compliance with the provisions of applicable state and federal securities laws, and the requirements of any securities exchanges on which the Company’s Shares may, at the time, be listed. The Committee may, in its discretion, to the extent permitted by Code Section 409A, if applicable, suspend the right to exercise Options or SARs to be settled in Shares, or delay the payment or settlement of any other Awards to be paid or settled in Shares, during any period in which the issuance of such Shares would not be in compliance with any applicable legal or securities exchange requirements. During any period in which the offering and issuance of Shares under the Plan are not registered under federal or state

securities laws, Participants shall acknowledge that they are acquiring Shares under the Plan for investment purposes and not for resale, and that Shares may not be transferred except pursuant to an effective registration statement under, or an exemption from the registration requirements of, such securities laws. Any book-entry or stock certificate evidencing Shares issued under the Plan that are subject to such securities law restrictions shall be accompanied by or bear an appropriate restrictive legend or stop transfer instruction. Notwithstanding any other provision of this Plan, the acquisition, holding or disposition of Shares acquired pursuant to the Plan shall in all events be subject to compliance with applicable Company policies, including those relating to insider trading, pledging or hedging transactions, minimum post-vesting holding periods and stock ownership guidelines, and to forfeiture or recovery of compensation as provided in Section 18(i).
(d)Other Benefit and Compensation Programs. Payments and other benefits received by a Participant under an Award made pursuant to the Plan shall not be deemed a part of a Participant’s regular, recurring compensation for purposes of the termination, indemnity or severance pay laws of any country or state and shall not be included in, nor have any effect on, the determination of benefits under any other employee benefit plan, contract or similar arrangement provided by the Company or an Affiliate unless expressly so provided by such other plan, contract or arrangement, or unless the Committee expressly determines that an Award or portion of an Award should be included to accurately reflect competitive compensation practices or to recognize that an Award has been made in lieu of a portion of competitive cash compensation.
(e)Governing Law. To the extent that federal laws do not otherwise control, the Plan and all determinations made and actions taken pursuant to the Plan shall be governed by the laws of the State of Minnesota without regard to its conflicts-of-law principles and shall be construed accordingly.
(f)Severability. If any provision of the Plan shall be held illegal or invalid for any reason, the illegality or invalidity shall not affect the remaining parts of the Plan, and the Plan shall be construed and enforced as if the illegal or invalid provision had not been included.
(g)Code Section 409A. It is intended that all Awards under the Plan will be exempt from, or will comply with, Code Section 409A, and to the maximum extent permitted the Awards the Plan will be limited, construed and interpreted in accordance with this intent. Notwithstanding anything to the contrary in the Plan or any Agreement, with respect to any Award that constitutes a deferral of compensation subject to Code Section 409A:
(1) If any amount is payable under such Award upon a termination of Service, a termination of Service will be deemed to have occurred only at such time as the Participant has experienced a “separation from service” as such term is defined for purposes of Code Section 409A; and
(2) If any amount shall be payable with respect to any such Award as a result of a Participant’s “separation from service” at such time as the Participant is a “specified employee” within the meaning of Code Section 409A, then no payment shall be made, except as permitted under Code Section 409A, prior to the first business day after the earlier of (i) the date that is six months after the Participant’s separation from Service or (ii) the Participant’s death. Unless the Committee has adopted a specified employee identification policy as contemplated by Code Section 409A, specified employees will be identified in accordance with the default provisions specified under Code Section 409A.
Each amount to be paid under an Award or this Plan shall be construed as a separate and distinct payment for purposes of Code Section 409A.
None of the Company, the Committee or any other person involved with the administration of this Plan shall (i) in any way be responsible for ensuring the exemption of any Award from, or compliance by any Award with, the requirements of Code Section 409A, (ii) have any duty or obligation to design or administer the Plan or Awards granted thereunder in a manner that minimizes a Participant’s tax liabilities, including the avoidance of any additional tax liabilities under Code Section 409A; or (iii) have any liability to any Participant for any such tax liabilities.

(h)Rule 16b-3. It is intended that the Plan and all Awards granted pursuant to it shall be administered by the Committee so as to permit the Plan and Awards to comply with Exchange Act Rule 16b-3. If any provision of the Plan or of any Award would otherwise frustrate or conflict with the intent expressed in this Section 18(h), that provision to the extent possible shall be interpreted and deemed amended in the manner determined by the Committee so as to avoid the conflict. To the extent of any remaining irreconcilable conflict with this intent, the provision shall be deemed void as applied to Participants subject to Section 16 of the Exchange Act to the extent permitted by law and in the manner deemed advisable by the Committee.
(i)Forfeiture and Compensation Recovery.
(1) The Committee may specify in an Agreement that the Participant’s rights, payments, and benefits with respect to an Award will be subject to reduction, cancellation, forfeiture or recovery by the Company upon the occurrence of certain specified events, in addition to any otherwise applicable vesting or performance conditions of an Award. Such events may include termination of Service for Cause, violation of any material Company or Affiliate policy, breach of noncompetition, non-solicitation or confidentiality provisions that apply to the Participant, a determination that the payment of the Award was based on an incorrect determination that financial or other criteria were met or other conduct by the Participant that is detrimental to the business or reputation of the Company or its Affiliates.
(2) Awards and any compensation associated therewith will be made subject to forfeiture, recovery by the Company or other action pursuant to any compensation recovery policy adopted by the Board or the Committee at any time, including in response to the requirements of Section 10D of the Exchange Act and any implementing rules and regulations thereunder, or as otherwise required by law. Any Agreement may be unilaterally amended by the Committee to comply with any such compensation recovery policy.
